    Cost and health outcome of primary percutaneous coronary intervention versus thrombolysis in acute ST-segment elevation myocardial infarction-Results of the Swedish Early Decision reperfusion Study (SWEDES) trial2010Ingår i: AMERICAN HEART JOURNAL, ISSN 0002-8703, Vol. 160, nr 2, s. 322-328Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. Methods Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. Results Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher in the PCI-treated group ($4,602 vs $3,807; P = .047), as well as the cost of drugs ($1,309 vs $1,202; P = .001), whereas the cost of hospitalization was lower ($7,344 vs $9,278; P = .025). The cost of investigations, outpatient care, and loss of production did not differ significantly between the 2 treatment arms. Total cost and quality-adjusted survival were $25,315 and 0.759 vs $27,819 and 0.728 (both not significant) for the primary PCI and thrombolysis groups, respectively. Based on the 1-year follow-up, bootstrap analysis revealed that in 80%, 88%, and 89% of the replications, the cost per health outcome gained for PCI will be andlt;$0, $50,000, and $100,000 respectively. Conclusion In a 1-year perspective, there was a tendency toward lower costs and better health outcome after primary PCI, resulting in costs for PCI in comparison to thrombolysis that will be below the conventional threshold for cost-effectiveness in 88% of bootstrap replications.

    A clinician’s experience of using the Cardiac Reader NT-proBNP point-of-care assay in a clinical setting2008Ingår i: European Journal of Heart Failure, ISSN 1388-9842, E-ISSN 1879-0844, Vol. 10, nr 3, s. 260-266Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The evaluation of natriuretic peptides has become increasingly valuable in a clinical setting, where information is often needed promptly.

    Objectives: To compare the usefulness of the recently released Roche Cardiac Reader ® NT-proBNP assay against the Roche Elecsys® NT-proBNP laboratory system in a clinical setting.

    Design and Results: Blood samples from 440 patients admitted for acute coronary syndromes, worsening of heart failure, or as policlinic heart failure patients were evaluated. The relation between the assays was analysed and the diagnostic concordance calculated. A good correlation was found between the assays (r=0.96, 95% CI: 0.94-0.97) with a diagnostic concordance of 0.93. A separate analysis was performed in the range where most clinical decisions are made (60-3000 ng/L), with a diagnostic concordance of 88%. The usefulness in a clinical setting where time is important was high.

    Conclusion: The Roche Cardiac Reader® NT-proBNP assay has been evaluated in a clinical setting. The point-of-care method shows good results, although with a restricted analytical range compared with the reference.

    Large early variation of residual platelet reactivity in Acute Coronary Syndrome patients treated with clopidogrel: Results from Assessing Platelet Activity in Coronary Heart Disease (APACHE).2015Ingår i: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 136, nr 2, s. 335-340Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    INTRODUCTION: There is a large inter-individual variation in response to clopidogrel treatment and previous studies have indicated higher risk of thrombotic events in patients with high residual platelet reactivity (HRPR), but the optimal time-point for testing is not established. The aim of this study was to investigate the optimal time-point for aggregometry testing and the risk of major adverse cardiac events associated with HRPR.

    METHOD AND RESULTS: We included 125 patients with ACS (73 with STEMI, and 71 received abciximab). The prevalence of HRPR varied substantially over time. The rate of HRPR in patients treated and not treated with abciximab were 43% vs 67% (p=0.01) before, 2% vs 23% (p=0.001) 6-8h after, 8% vs 9% (p=0.749) 3days after, and 23% vs 12% (p=0.138) 7-9 days after loading dose of clopidogrel. We found HRPR in 18% of the patients but only four ischemic events during 6months follow-up, with no significant difference between HRPR patients compared to the rest of the population. There were 3 TIMI major bleedings, all of which occurred in the low residual platelet reactivity (LRPR) group.

    CONCLUSION: There is a large variation in platelet reactivity over time, also depending on adjunctive therapy, which has a large impact on optimal time-point for assessment. We found HRPR in almost 1 in 5 patients, but very few MACE, and not significantly higher in HRPR patients. In a contemporary ACS population, with low risk for stent thrombosis, the predictive value of HRPR for ischemic events will probably be low.

    Management of pancreatic pseudocysts.1989Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 76, nr 6, s. 550-552Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Between 1969 and 1987, 68 patients with pancreatic pseudocysts were treated. The median cyst size was 10 cm (range 2-25 cm). Nine patients were managed conservatively with resolution of the pseudocyst occurring in eight patients. These patients had significantly smaller (median 4 cm) cysts compared with those in both percutaneously and surgically treated patients (P less than 0.01). In 22 patients the pseudocysts (median 9 cm) were punctured percutaneously under ultrasound guidance and the cyst fluid was aspirated or drained through a catheter. Complete resolution occurred in 13 patients after 1-4 (mean 1.8) punctures per patient, regression occurred in six patients after 1-4 (mean 2.0) puncture procedures per patient and three were unchanged. No complications were noted, except that two patients treated percutaneously required additional surgery. Thirty-seven patients were managed surgically (median cyst size 11 cm) with external drainage (12 patients), cystgastrostomy (17 patients), cystduodenostomy (three patients) cystjejunostomy (three patients) and pancreatic resection (two patients). Resolution of the cyst was noted in 29 patients, regression in five and three were unchanged. Five patients required additional surgery. Twelve complications were seen in ten patients (27 per cent), most frequently after external drainage. One patient died after surgical treatment. Mean hospital stay was 13 days among patients treated conservatively and 30 days in both percutaneously and surgically treated patients. Aspiration or catheter drainage of pseudocyst fluid guided by ultrasonography seems a safe and effective treatment of pancreatic pseudocysts and should be considered as initial therapy. If surgery is required cystgastrostomy is preferred.

    The cost-effectiveness of radiofrequency catheter ablation as first-line treatment for paroxysmal atrial fibrillation: results from a MANTRA-PAF substudy.2015Ingår i: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, nr 1, s. 48-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    AIM: The aim of this prospective substudy was to estimate the cost-effectiveness of treating paroxysmal atrial fibrillation (AF) with radiofrequency catheter ablation (RFA) compared with antiarrhythmic drugs (AADs) as first-line treatment.

    METHODS AND RESULTS: A decision-analytic Markov model, based on MANTRA-PAF (Medical Antiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation) study data, was developed to study long-term effects and costs of RFA compared with AADs as first-line treatment. Positive clinical effects were found in the overall population, a gain of an average 0.06 quality-adjusted life years (QALYs) to an incremental cost of €3033, resulting in an incremental cost-effectiveness ratio of €50 570/QALY. However, the result of the subgroup analyses showed that RFA was less costly and more effective in younger patients. This implied an incremental cost-effectiveness ratio of €3434/QALY in ≤50-year-old patients respectively €108 937/QALY in >50-year-old patients.

    CONCLUSION: Radiofrequency catheter ablation as first-line treatment is a cost-effective strategy for younger patients with paroxysmal AF. However, the cost-effectiveness of using RFA as first-line therapy in older patients is uncertain, and in most of these AADs should be attempted before RFA (MANTRA-PAF ClinicalTrials.gov number; NCT00133211).

    Abciximab bolus with optional infusion in intervention for ST-elevation myocardial infarction2013Ingår i: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 47, nr 4, s. 230-235Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives. The standard abciximab regimen is a bolus dose followed by a 12-h infusion. Whether the bolus dose alone is sufficient for ST-elevation myocardial infarction patients receiving a high loading dose of clopidogrel is unknown. Design. In an observational study, 693 consecutive patients were treated with abciximab during percutaneous coronary intervention for ST-elevation myocardial infarction. Totally 354 patients received standard strategy of abciximab bolus and infusion followed by 339 patients that recieved abciximab bolus only (271 patients) or bolus and infusion if suboptimal result (68 patients) in combination with a higher loading dose of clopidogrel (600 mg) the modified strategy. Results. The two groups were similar regarding baseline characteristics and in hospital bleeding events. At 30 days, the composite of death, re-infarction or target vessel revascularization was 9.1% in the standard and 7.5% in the modified strategy (p = 0.45). The rate of stent thrombosis was lower in the modified strategy group with 0% and 2.3% in the standard group (pandlt;0.001) and the mean total medical cost was lower in the modified strategy group with 8032 and 8665 in the standard group (pandlt;0.001). Conclusions. In primary percutaneous coronary intervention with a loading dose of 600 mg clopidogrel, it seems safe and cost-saving to give abciximab bolus with optional infusion.

    Costs of bleeds relating to acute coronary syndrome therapies.2010Ingår i: Journal of Medical Economics, ISSN 1369-6998, Vol. 13, nr 2, s. 236-240Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To estimate the costs to manage selected types of bleeding complications in patients with acute coronary syndrome (ACS) treated with antithrombotics, including antiplatelet, and fibrinolytic therapies: decrease in haemoglobin >3 g/dL, puncture site, and bleeding requiring transfusion of blood products.

    Methods: Retrospective chart reviews of ACS patients experiencing decrease in Hb, puncture site, or bleeding requiring transfusion were conducted in hospitals in France, Germany, Italy, Spain and Sweden to determine the total length of stay (LOS), stay post-bleeding, procedures to identify the extent of bleeding, number and types of transfusion products, patient demographics, reason for hospital admission and disposition upon discharge. Country-specific costs were applied to estimate the average cost per patient by type of bleeding event.

    Results: Records of 158 ACS patients with the bleeding complications were examined (26.9% decrease in Hb, 35.5% puncture site, and 37.8% transfusion). The average LOS was 10.6 days for decreasing Hb, 7.7 days for puncture site bleeding, and 11.3 days for patients receiving transfusions due to these bleeding events. The average costs per patient ranged between €3,986 and €10,252. The LOS ranged widely both within and across countries.

    Limitations: The study has a small sample size and costs are confounded by co-morbidities.

    Conclusions: The estimated costs for decreasing Hb, puncture site bleeding and bleeding resulting in transfusions provide a tool for researchers to conduct economic analyses of bleeding events associated with therapies for ACS.

    Impact of age on the effect of pre-hospital P2Y12 receptor inhibition in primary percutaneous coronary intervention for ST-segment elevation myocardial infarction: the ATLANTIC-Elderly analysis2018Ingår i: EuroIntervention, ISSN 1774-024X, E-ISSN 1969-6213, Vol. 14, nr 7, s. 789-797, artikel-id EIJ-D-18-00182Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    AIMS: The aim of the study was to examine the main results of the ATLANTIC trial in patients with ST-elevation myocardial infarction (STEMI), randomised to pre- versus in-hospital ticagrelor, according to age.

    METHODS AND RESULTS: Patients were evaluated by age class (<75 vs. ≥75 years) for demographics, prior cardiovascular history, risk factors, management, and outcomes. Elderly patients (≥75 years; 304/1,862) were more likely to be women, diabetic, lean, with a prior history of myocardial infarction and CABG, and with comorbidities (p<0.01 for all). Elderly patients presented more frequently with acute heart failure and less frequently had thromboaspiration, a stent implanted (p<0.01) and an aggressive antithrombotic regimen. Elderly patients had lower rates of pre- and post-PCI ≥70% ST-segment elevation resolution (43.9% vs. 51.6%; p=0.035), of pre- and post-PCI TIMI 3 flow (17.1% vs. 27.5%, p=0.0002), and a higher rate of the composite of death/MI/stroke/urgent revascularisation (9.9% vs. 2.9%; OR 3.67, 95% CI [2.27; 5.93], p<0.0001) and mortality (8.5% vs. 1.5%; OR 6.45, 95% CI [2.75; 15.11], p<0.0001). There was a non-significant trend towards more frequent major bleedings among elderly patients (TIMI major 2.3% vs. 1.1%; OR 2.13, 95% CI [0.88; 5.18], p=0.095). There was no significant interaction between time of ticagrelor administration (pre-hospital versus in-lab) and class of age for all outcomes.

    CONCLUSIONS: Elderly patients, who represented one sixth of the patients randomised in the ATLANTIC trial, had less successful mechanical reperfusion and a sixfold increase in mortality at 30 days, probably due to comorbidities and possible undertreatment. The effect of early ticagrelor was consistent irrespective of age.

    Economic Analysis of Ticagrelor Therapy From a US Perspective2015Ingår i: Journal of the American College of Cardiology, ISSN 0735-1097, E-ISSN 1558-3597, Vol. 65, nr 5, s. 465-476Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND Based on results of the PLATO (Platelet Inhibition and Patient Outcomes) trial comparing ticagrelor with clopidogrel therapy, the U.S. Food and Drug Administration approved ticagrelor in 2011 for reducing thrombotic cardiovascular events in patients with acute coronary syndrome (ACS) with the proviso that it be taken with low-dose aspirin. OBJECTIVES This study sought to assess the cost and cost effectiveness of ticagrelor therapy relative to clopidogrel in treating ACS patients from the perspective of the U.S. health care system. METHODS We estimated within-trial resource use and costs using U.S. low-dose aspirin patients in PLATO (n = 547). Quality-adjusted life expectancy was estimated using the total PLATO population (n = 18,624), combined with baseline risk and long-term survival data from an external ACS patient cohort. Study drugs were valued at current costs. Cost effectiveness was assessed, as was the sensitivity of results to sampling and methodological uncertainties. RESULTS One year of ticagrelor therapy, relative to that of generic clopidogrel, cost $29,665/quality-adjusted life-year gained, with 99% of bootstrap estimates falling under a $100,000 willingness-to-pay threshold. Results were robust to extensive sensitivity analyses, including variations in clopidogrel cost, exclusion of costs in extended years of life, and a recalibrated estimate of survival reflecting a lower underlying mortality risk in the United States. CONCLUSIONS For PLATO-eligible ACS patients, a U.S. perspective comparison of the current standard of dual antiplatelet therapy of aspirin with clopidogrel versus aspirin plus ticagrelor showed that the ticagrelor regimen increased life expectancy at an incremental cost well within accepted benchmarks of good value for money.

    CMT rapport: kostnader och kostnadseffektivitet av ett införande av dabigatran hos patienter med förmaksflimmer2011Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Förmaksflimmer är den vanligaste arytmin i Sverige och orsakar stora kostnader inom hälso- och sjukvården. Förutom att patienterna vanligen drabbas av försämrad livskvalitet går det också åt stora resurser för komplikationer i form av tromboembolier och stroke. De flesta behandlingar inom förmaksflimmer kombineras med antikoagulationsbehandling för att förebygga eller förhindra uppkomst av tromboembolier och ischemisk stroke. Vid denna behandling krävs noggrann dosering för att sänka risken för stroke utan att kraftigt höja risken för blödningar. Warfarin har under lång tid varit det mest effektivaantikoagulationsläkemedlet för skydd mot tromboembolier vid  förmaksflimmer. Ett annat behandlingsalternativ är acetylsalicylsyra (ASA). Ett nytt antikoagulationsläkemedel som heter dabigatran (Pradaxa®) har nyligen godkänts som förebyggande behandling av stroke och systemisk embolism hos patienter med förmaksflimmer. Dabigatran har i en stor studie, (RE-LY), visat sig reducera risken för stroke jämfört med warfarin.

    Det övergripande syftet med denna rapport är att beräkna hälsoekonomiska konsekvenser i form av kostnader och kostnadseffektivitet av ett införande av dabigatran (Pradaxa®) som förebyggande behandling av stroke och systemisk embolism hos patienter med förmaksflimmer. I grundanalysen analyseras dabigatran 150 mg två gånger per dag för personer som är under 80 år och dabigatran 110 mg två gånger per dag för personer 80 år eller äldre. Jämförelser görs med warfarin och ASA, och warfarinbehandlingen delas dessutom in i tre subgrupper; välinställda, dåligt inställda samt warfarin-naïva patienter.

    En simuleringsmodell har skapats för att beräkna långsiktiga kostnader och effekter för de olika behandlingsalternativen. Effekterna mäts i antal förhindrade stroke, antal vunna levnadsår samt antal vunna kvalitetsjusterade levnadsår (QALYs). Priset för de båda dagliga doserna av dabigatran (150 mg gånger två och 110 mg gånger två) är 25,39 kronor per dag.

    Analyserna i den här rapporten visar att kostnaden för förmaksflimmer i Sverige beräknas till drygt 4,1 miljarder kronor år 2010. Denna kostnad förväntas sjunka vid införande av dabigatran, till följd av besparingar inom vården av stroke och ett sänkt produktionsbortfall. Kostnaden per vunnet QALY för dabigatran 150 mg / 110 mg jämfört med warfarin, hos patienter som är 65 år gamla och följs upp i 20 år, har beräknats till 74 216 kronor. Vid jämförelse med välinställd warfarinbehandling höjs kostnaden per vunnet QALY till 107 186 kronor. Om dabigatran 110 mg två gånger dagligen jämförs med ASA leder det till lägre kostnader och bättre effekter, vilket innebär att dabigatran 110 mg två gånger dagligen är en dominant behandling för patienter som inte är lämpliga för warfarinbehandling.

    Ett införande av dabigatran leder till kostnadsförskjutningar inom flera olika områden. En ökad kostnad uppkommer för läkemedel, medan  sänkta kostnader uppkommer till följd av färre stroke. För patienten innebär dabigatran lägre risk för stroke och färre besök i sjukvården.

    The Cost of Thromboembolic Events and their Prevention among Patients with Atrial Fibrillation2011Ingår i: Journal of Atrial Fibrillation, ISSN 1941-6911, Vol. 2, nr 4, s. 00-00Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. People with AF have a significantly increased risk of thromboembolic events, including stroke, and the main treatment is therefore aimed at preventing thromboembolic events via anticoagulation with warfarin or acetylsalicylic acid. However, the development of new anticoagulation treatments has prompted a need to know the current cost of AF-related thromboembolic events, for future cost-effectiveness comparisons with the existing treatments. In this study, we estimated the cost of thromboembolic events and their prevention among Swedish AF patients in 2010.

    Methods: The relevant costs were identified, quantified, and valued. The complications included were ischaemic and haemorrhagic stroke, gastrointestinal bleeding, and other types of major bleeding caused by AF. Treatments intended to lower the risk of ischaemic stroke were also included. A societal perspective was used, including productivity loss due to morbidity. Patients with a CHADS2 score of 1 or higher were included.

    Results: Among the 9 340 682 inhabitants of Sweden, there are 118 000 patients with AF and at least one more risk factor for stroke, comprising 1.26% of the population. Of these patients, 43.3% are treated with warfarin, 28.3% use acetylsalicylic acid, and 28.3% are assumed to have no anticoagulation treatment. The cost of AF-related complications and its prevention in Sweden was estimated at €437 million for 2010, corresponding to €3 712 per AF patient per year. The highest cost was caused by stroke, and the second highest by the cost of monitoring the warfarin treatment. As the prevalence of AF is expected to increase in the future, AF-related costs are also expected to rise.

    Conclusion: Thromboembolic events cause high costs. New, easily-administered treatments that could reduce the risk of stroke have the potential to be cost-effective.

    Cost-effectiveness of dabigatran compared with warfarin for patients with atrial fibrillation in Sweden2013Ingår i: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 34, nr 3, s. 177-183Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Patients with atrial fibrillation have a significantly increased risk of thromboembolic events such as ischaemic stroke, and patients are therefore recommended to be treated with anticoagulation treatment. The most commonly used anticoagulant consists of vitamin K antagonist such as warfarin. A new oral anticoagulation treatment, dabigatran, has recently been approved for stroke prevention among patients with atrial fibrillation. The purpose of this study was to estimate the cost-effectiveness of dabigatran as preventive treatment of stroke and thromboembolic events compared with warfarin in 65-year-old patients with atrial fibrillation in Sweden. less thanbrgreater than less thanbrgreater thanA decision analytic simulation model was used to estimate the long-term (20-year) costs and effects of the different treatments. The outcome measures are the number of strokes prevented, life years gained, and quality-adjusted life years (QALYs) gained. Costs and effect data are adjusted to a Swedish setting. Patients below 80 years of age are assumed to start with dabigatran 150 mg twice a day and switch to 110 mg twice a day at the age of 80 years due to higher bleeding risk. The price of dabigatran in Sweden is Euro2.82 (Swedish kronor 25.39) per day for both doses. The cost per QALY gained for dabigatran compared with warfarin is estimated at Euro7742, increasing to Euro12 449 if dabigatran is compared with only well-controlled warfarin treatment. less thanbrgreater than less thanbrgreater thanDabigatran is a cost-effective treatment in Sweden, as its incremental cost-effectiveness ratio is below the normally accepted willingness to pay limit.

    Direct valuation of health state among patients with chest pain: Does income level matterManuskript (preprint) (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    There is still uncertainty over where to include the production loss caused by morbidity in cost-effectiveness analyses. This loss could be included as a cost; but if individuals take their own income into consideration when valuing health states, this would lead to double counting. The purpose of this study was to find out whether individuals’ incomes can explain their valuations of their own current health states.

    The sample consisted of 156 patients (312 observations) admitted to hospital with chest pain (the FRISC II trial). These patients valued their own current health states by using the time trade-off method (TTO) and a visual analogue scale (VAS). They also answered the EQ-5D instrument and stated their monthly income. Income level was additionally controlled via their taxed income at the tax agency, together with their income generated from capital. Generalised estimation equations were used to test whether the EQ- 5D dimensions and monthly gross income could explain the variation in the valuations of the health states.

    The results indicate that neither self-stated nor taxed income could explain the variation in the valuations made by TTO. However, self-stated income (but not taxed income) was a significant variable in explaining variation in the VAS valuations.

    These findings support the inclusion of the production loss caused by morbidity in the analysis, as these costs are not, or at least not to any great extent, implicitly incorporated in the individuals’ QALY weights when TTO is used to value the health states. Using a VAS, some income effects may be included.

    Software-based on-site estimation of fractional flow reserve using standard coronary CT angiography data.2016Ingår i: Acta Radiologica, ISSN 0284-1851, E-ISSN 1600-0455, Vol. 57, nr 10, s. 1186-1192Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The significance of a coronary stenosis can be determined by measuring the fractional flow reserve (FFR) during invasive coronary angiography. Recently, methods have been developed which claim to be able to estimate FFR using image data from standard coronary computed tomography angiography (CCTA) exams.

    PURPOSE: To evaluate the accuracy of non-invasively computed fractional flow reserve (cFFR) from CCTA.

    MATERIAL AND METHODS: A total of 23 vessels in 21 patients who had undergone both CCTA and invasive angiography with FFR measurement were evaluated using a cFFR software prototype. The cFFR results were compared to the invasively obtained FFR values. Correlation was calculated using Spearman's rank correlation, and agreement using intraclass correlation coefficient (ICC). Sensitivity, specificity, accuracy, negative predictive value, and positive predictive value for significant stenosis (defined as both FFR ≤0.80 and FFR ≤0.75) were calculated.

    RESULTS: The mean cFFR value for the whole group was 0.81 and the corresponding mean invFFR value was 0.84. The cFFR sensitivity for significant stenosis (FFR ≤0.80/0.75) on a per-lesion basis was 0.83/0.80, specificity was 0.76/0.89, and accuracy 0.78/0.87. The positive predictive value was 0.56/0.67 and the negative predictive value was 0.93/0.94. The Spearman rank correlation coefficient was ρ = 0.77 (P < 0.001) and ICC = 0.73 (P < 0.001).

    CONCLUSION: This particular CCTA-based cFFR software prototype allows for a rapid, non-invasive on-site evaluation of cFFR. The results are encouraging and cFFR may in the future be of help in the triage to invasive coronary angiography.

    European registry on patients with ST-elevation myocardial infarction transferred for mechanical reperfusion with a special focus an early administration of abciximab-EUROTRANSFER Registry2008Ingår i: American Heart Journal, ISSN 0002-8703, E-ISSN 1097-6744, Vol. 156, nr 6, s. 1147-1154Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Abciximab is established as adjunct to primary percutaneous coronary intervention (PCI). Based on some smaller studies, ST-segment elevation myocardial infarction (STEMI) networks in various European countries have adopted the start of abciximab before transfer to the catheterization laboratory (cathlab) hospital as part of their routine treatment options. Although a recently published study did not reveal improved clinical outcome when starting abciximab before the cathlab, a potential benefit from such early administration, in particular in the setting of transfer networks, remains unclear and has been the subject of debate.

    Methods: Data of consecutive patients with STEMI transferred for primary PCI in hospital/ambulance-feeded STEMI networks treated between November 2005 and January 2007 at 15 PCI centers from 7 European countries were collected in the web-based EUROTRANSFER Registry.

    Results: Data from a total of 1,650 patients were collected. Abciximab was administered to 1086 patients (66%), of whom 727 received early abciximab (EA group: abciximab started before admission to cathlab, at least 30 minutes before balloon). Another 359 patients received late abciximab (LA group: periprocedural administration of abciximab in the cathlab). Preprocedural TIMI 3 flow was observed in 17.7% of patients with EA and in 8.9% in the LA group (P < .0001). Thirty-day mortality was 3.9% in the EA group versus 7.5% with LA (OR 0.49, 95% CI 0.29-0.85, P = .011), and composite 30-day outcome including death, repeated myocardial infarction, and urgent revascularization was present in 5.5% and 10.3%, respectively (OR 0.5 1, 95% CI 0.32-0.81, P = .004). These differences remain statistically significant in favor of early abciximab after accounting and adjustment for differences between the groups by means of a multivariate regression model and propensity score.

    Conclusions: Patients in STEMI networks transferred for primary PCI who have received abciximab before transfer rather than in the cathlab had more patent arteries before PCI and showed lower rates for death and the composite clinical outcome at 30-day follow-up.

    Early abciximab administration before primary percutaneous coronary intervention improves clinical outcome in diabetic patients with ST-segment elevation myocardial infarction (EUROTRANSFER Registry)2012Ingår i: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 223, nr 1, s. 212-218Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Diabetes is an important determinant of prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Limited data are available concerning benefits and risks of upstream abciximab administration in diabetic patients. Thus, the objective of the study was to assess the impact of early abciximab administration before primary angioplasty (PCI) for STEMI in diabetic patients. Methods: Data were gathered for 1650 consecutive STEMI patients transferred for primary PCI from hospital networks in seven countries in Europe from November 2005 to January 2007 (the EURO-TRANSFER Registry population). Patients were stratified by diabetes mellitus presence and then by abciximab administration strategy (early - more than 30 min before PCI vs. late). Results: Diabetes mellitus was diagnosed in 262 (15.9%) patients. Patients with diabetes mellitus were high-risk individuals, with advanced age, higher prevalence of comorbidities and increased risk of ischemic events during follow-up in comparison to non-diabetic patients. A total of 1086 patients who received abciximab were identified. Strategy of early abciximab administration was associated with enhanced infarct-related artery patency before PCI, and improved epicardial flow after PCI in both diabetic and non-diabetic patients. Importantly, early abciximab in diabetic patients led to the decrease in ischemic events, including 30-day (OR 0.260, 95% CI 0.089-0.759, p = 0.012) and 1-year (OR 0.273, 95% CI 0.099-0.749, p = 0.012) mortality reduction. However, only a trend toward improved survival was confirmed after adjustment for potential confounders. On the contrary, the reduction of 30-day (OR 0.620, 95% CI 0.334-1.189, p = 0.16) and 1-year (OR 0.643, 95% CI 0.379-1.089, p = 0.10) mortality rates was not significant among non-diabetic patients. Conclusions: Early administration of abciximab improves infarct-related artery patency before and after primary PCI, and leads to improved survival in diabetic STEMI patients.

    Early abciximab administration before primary percutaneous coronary intervention improves clinical outcome in elderly patients transferred with ST-elevation myocardial infarction Data from the EUROTRANSFER registry2010Ingår i: INTERNATIONAL JOURNAL OF CARDIOLOGY, ISSN 0167-5273, Vol. 143, nr 2, s. 147-153Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Limited data are available concerning benefits and risks of early abciximab (EA) administration before primary percutaneous coronary intervention (PPCI) in elderly ST-segment elevation myocardial infarction (STEMI) patients. The objective of the study was to assess the impact of EA before PPCI in elderly (andgt;= 65 years) patients. Methods and results: We identified 545 patients andlt;65 years (354 with EA administration (andgt;30 min before PPCI), 191 late abciximab (LA)), and 541 patients andgt;= 65 years of age (373 EA, 168 LA) in the EUROTRANSFER Registry database. Elderly patients were more likely to have comorbidities, angiographic PCI complications, and bleeding events. EA promotes infarct-related artery patency before PPCI and improves myocardial reperfusion after PPCI in both age groups, but the risk of 30-day death (EA vs. LA: andlt;65 years, 2.0% vs. 1.6%; p = 0.999; andgt;= 65 years, 5.9% vs. 14.3%; p = 0.001) and 30-day death + reinfarction (EA vs. LA: andlt;65 years, 2.5% vs. 2.1%; p = 0.999; andgt;= 65 years, 7.5% vs. 17.3%; p = 0.001) was reduced in elderly patients only. There was no difference in bleedings, especially major bleedings requiring transfusion (EA vs. LA: patients andlt;65 years, 2.3% vs. 0%, p = 0.055; andgt;= 65 years, 2.4% vs. 3%; p = 0.448) between groups. Conclusions: Patients andgt;= 65 years of age have a substantially increased risk of angiographic PCI complications, death and bleeding events compared with their younger counterparts. Strategy of EA before PPCI improves reperfusion parameters and clinical outcome in elderly patients and is not associated with elevated risk of major bleeding.

    Compilation of cost-effectiveness evidence for different heart conditions and treatment strategies2011Ingår i: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 45, nr 2, s. 72-76Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Objectives. Despite the continuing interest in health economic research, we could find no accessible data set on cost-effectiveness, useful as practical information to decision makers who must allocate scarce resources within the cardiovascular field. The aim of this paper was to present cost-effectiveness ratios, based on a systematic literature search for the treatment of heart diseases. Design. A comprehensive literature search on cost-effectiveness analyses of intervention strategies for the treatment of heart diseases was conducted. We compiled available cost-effectiveness ratios for different heart conditions and treatment strategies, in a cost-effectiveness ranking table. The cost-effectiveness ratios were expressed as a cost per quality adjusted life year (QALY) or life year gained. Results. Cost-effectiveness ratios, ranging from dominant to those costing more than 1,000,000 Euros per QALY gained, and bibliographic references are provided for. The table was categorized according to disease group, making the ranking table readily available. Conclusions. Cost-effectiveness ranking tables provide a means of presenting cost-effectiveness evidence. They provide valid information within a limited space aiding decision makers on the allocation of health care resources. This paper represents an extensive compilation of health economic evidence for the treatment of heart diseases.

    Use of cost-effectiveness data in priority setting decisions: experiences from the national guidelines for heart diseases in Sweden2014Ingår i: International Journal of Health Policy and Management, ISSN 2322-5939, E-ISSN 2322-5939, Vol. 3, nr 6, s. 323-332Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The inclusion of cost-effectiveness data, as a basis for priority setting rankings, is a distinguishing feature in the formulation of the Swedish national guidelines. Guidelines are generated with the direct intent to influence health policy and support decisions about the efficient allocation of scarce healthcare resources. Certain medical conditions may be given higher priority rankings i.e. given more resources than others, depending on how serious the medical condition is. This study investigated how a decision-making group, the Priority Setting Group (PSG), used cost-effectiveness data in ranking priority setting decisions in the national guidelines for heart diseases.

    METHODS: A qualitative case study methodology was used to explore the use of such data in ranking priority setting healthcare decisions. The study addressed availability of cost-effectiveness data, evidence understanding, interpretation difficulties, and the reliance on evidence. We were also interested in the explicit use of data in ranking decisions, especially in situations where economic arguments impacted the reasoning behind the decisions.

    RESULTS: This study showed that cost-effectiveness data was an important and integrated part of the decision-making process. Involvement of a health economist and reliance on the data facilitated the use of cost-effectiveness data. Economic arguments were used both as a fine-tuning instrument and a counterweight for dichotomization. Cost-effectiveness data were used when the overall evidence base was weak and the decision-makers had trouble making decisions due to lack of clinical evidence and in times of uncertainty. Cost-effectiveness data were also used for decisions on the introduction of new expensive medical technologies.

    CONCLUSION: Cost-effectiveness data matters in decision-making processes and the results of this study could be applicable to other jurisdictions where health economics is implemented in decision-making. This study contributes to knowledge on how cost-effectiveness data is used in actual decision-making, to ensure that the decisions are offered on equal terms and that patients receive medical care according their needs in order achieve maximum benefit.

    Reaching agreement in uncertain circumstances: the practice of evidence-based policy in the case of the Swedish National Guidelines for heart diseases2017Ingår i: Evidence and Policy: A Journal of Research, Debate and Practice, ISSN 1744-2648, nr 4, s. 687-707Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper explores the practice of evidence-based policy in a Swedish healthcare context. The study focused on how policymakers in the specific working group, the Priority-Setting Group (PSG), handled the various forms of evidence and values and their competing rationalities, when producing the Swedish National Guidelines for heart diseases that are based on both clinical and economic evidence and are established to support explicit priority-setting in healthcare. The study contributes to the theoretical and practical debate on evidence-based policy (EBP) by illustrating how the practical tensions of coming to agreement were managed, to a large extent, through deliberation and by creativity.

    Frailty is independently associated with 1-year mortality for elderly patients with non-ST-segment elevation myocardial infarction2014Ingår i: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 21, nr 10, s. 1216-1224Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: For the large population of elderly patients with cardiovascular disease, it is crucial to identify clinically relevant measures of biological age and their contribution to risk. Frailty is denoting decreased physiological reserves and increased vulnerability. We analysed the manner in which the variable frailty is associated with 1-year outcomes for elderly non-ST-segment elevation myocardial infarction (NSTEMI) patients. METHODS AND RESULTS: Patients aged 75 years or older, with diagnosed NSTEMI were included at three centres, and clinical data including judgment of frailty were collected prospectively. Frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale. Of 307 patients, 149 (48.5%) were considered frail. By Cox regression analyses, frailty was found to be independently associated with 1-year mortality after adjusting for cardiovascular risk and comorbid conditions (hazard ratio 4.3, 95% CI 2.4-7.8). The time to the first event was significantly shorter for frail patients than for nonfrail (34 days, 95% CI 10-58, p = 0.005). CONCLUSIONS: Frailty is strongly and independently associated with 1-year mortality. The combined use of frailty and comorbidity may constitute an important risk prediction concept in regard to cardiovascular patients with complex needs.

    Frailty as a Predictor of Short-Term Outcomes for Elderly Patients with non-ST-Elevation Myocardial Infarction (NSTEMI)Manuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    Background – For the large and growing population of elderly patients with cardiovascular disease it is important to identify clinically relevant measures of biological age and their contribution to risk. Frailty is an emerging concept in medicine denoting increased vulnerability and decreased physiologic reserves. We analyzed how the variable frailty predicts short-term outcomes for elderly NSTEMI patients.

    Methods and Results – Patients, aged 75 years or older, with diagnosed NSTEMI were included at three centers, and clinical data including judgement of frailty were collected prospectively. Frailty was defined according to the Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS). Of 307 patients, 150 (48.5%) were considered frail. Frail patients were slightly older and presented with a greater burden of comorbidity. By multiple logistic regression, frailty was found to be a strong independent risk factor for inhospital mortality, one-month mortality (OR 3.8, 95% CI 1.3 to 10.8) and the primary composite outcome (OR 2.2, 95% CI 1.3 to 3.7). Particularly frail patients with a high comorbidity burden manifested a markedly increased risk for the primary composite outcome. By multiple linear regression, frailty was identified as a strong independent predictor for prolonged hospital care (frail 13.4 bed days, non-frail 7.5 bed days; P<0.0001).

    Conclusions - Frailty is a strong independent predictor of in-hospital mortality, one-month mortality, prolonged hospital care and the primary composite outcome. The combined use of frailty and comorbidity may constitute an ultimate risk prediction concept regarding cardiovascular patients with complex needs.

    Frailty Is Independently Associated With Short-Term Outcomes for Elderly Patients With Non-ST-Segment Elevation Myocardial Infarction2011Ingår i: Circulation, ISSN 0009-7322, E-ISSN 1524-4539, Vol. 124, nr 22, s. 2397-2404Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: For the large and growing population of elderly patients with cardiovascular disease, it is important to identify clinically relevant measures of biological age and their contribution to risk. Frailty is an emerging concept in medicine denoting increased vulnerability and decreased physiological reserves. We analyzed the manner in which the variable frailty predicts short-term outcomes for elderly non-ST-segment elevation myocardial infarction patients.

    Methods and results: Patients aged ≥ 75 years, with diagnosed non-ST-segment elevation myocardial infarction were included at 3 centers, and clinical data including judgment of frailty were collected prospectively. Frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale. The impact of the comorbid conditions on risk was quantified by the coronary artery disease-specific index. Of 307 patients, 149 (48.5%) were considered frail. By multiple logistic regression, frailty was found to be strongly and independently associated with risk for the primary composite outcome (death from any cause, myocardial reinfarction, revascularization due to ischemia, hospitalization for any cause, major bleeding, stroke/transient ischemic attack, and need for dialysis up to 1 month after inclusion) (odds ratio, 2.2; 95% confidence interval, 1.3-3.7) in-hospital mortality (odds ratio, 4.6; 95% confidence interval, 1.3-16.8), and 1-month mortality (odds ratio, 4.7; 95% confidence interval, 1.7-13.0).

    Conclusions: Frailty is strongly and independently associated with in-hospital mortality, 1-month mortality, prolonged hospital care, and the primary composite outcome. The combined use of frailty and comorbidity may constitute an ultimate risk prediciton concept in regard to cardiovascular patients with complex needs.

    The effectiveness and cost-effectiveness of biomarkers for the prioritisation of patients awaiting coronary revascularisation: a systematic review and decision model.2010Ingår i: Health Technology Assessment, ISSN 1366-5278, Vol. 14, nr 9, s. 1-178Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To determine the effectiveness and cost-effectiveness of a range of strategies based on conventional clinical information and novel circulating biomarkers for prioritising patients with stable angina awaiting coronary artery bypass grafting (CABG).

    DATA SOURCES: MEDLINE and EMBASE were searched from 1966 until 30 November 2008.

    REVIEW METHODS: We carried out systematic reviews and meta-analyses of literature-based estimates of the prognostic effects of circulating biomarkers in stable coronary disease. We assessed five routinely measured biomarkers and the eight emerging (i.e. not currently routinely measured) biomarkers recommended by the European Society of Cardiology Angina guidelines. The cost-effectiveness of prioritising patients on the waiting list for CABG using circulating biomarkers was compared against a range of alternative formal approaches to prioritisation as well as no formal prioritisation. A decision-analytic model was developed to synthesise data on a range of effectiveness, resource use and value parameters necessary to determine cost-effectiveness. A total of seven strategies was evaluated in the final model.

    RESULTS: We included 390 reports of biomarker effects in our review. The quality of individual study reports was variable, with evidence of small study (publication) bias and incomplete adjustment for simple clinical information such as age, sex, smoking, diabetes and obesity. The risk of cardiovascular events while on the waiting list for CABG was 3 per 10,000 patients per day within the first 90 days (184 events in 9935 patients with a mean of 59 days at risk). Risk factors associated with an increased risk, and included in the basic risk equation, were age, diabetes, heart failure, previous myocardial infarction and involvement of the left main coronary artery or three-vessel disease. The optimal strategy in terms of cost-effectiveness considerations was a prioritisation strategy employing biomarker information. Evaluating shorter maximum waiting times did not alter the conclusion that a prioritisation strategy with a risk score using estimated glomerular filtration rate (eGFR) was cost-effective. These results were robust to most alternative scenarios investigating other sources of uncertainty. However, the cost-effectiveness of the strategy using a risk score with both eGFR and C-reactive protein (CRP) was potentially sensitive to the cost of the CRP test itself (assumed to be 6 pounds in the base-case scenario).

    CONCLUSIONS: Formally employing more information in the prioritisation of patients awaiting CABG appears to be a cost-effective approach and may result in improved health outcomes. The most robust results relate to a strategy employing a risk score using conventional clinical information together with a single biomarker (eGFR). The additional prognostic information conferred by collecting the more costly novel circulating biomarker CRP, singly or in combination with other biomarkers, in terms of waiting list prioritisation is unlikely to be cost-effective.

    Assessing the cost effectiveness of using prognostic biomarkers with decision models: case study in prioritising patients waiting for coronary artery surgery2010Ingår i: BRITISH MEDICAL JOURNAL, ISSN 0959-535X, Vol. 340Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective To determine the effectiveness and cost effectiveness of using information from circulating biomarkers to inform the prioritisation process of patients with stable angina awaiting coronary artery bypass graft surgery. Design Decision analytical model comparing four prioritisation strategies without biomarkers (no formal prioritisation, two urgency scores, and a risk score) and three strategies based on a risk score using biomarkers: a routinely assessed biomarker (estimated glomerular filtration rate), a novel biomarker (C reactive protein), or both. The order in which to perform coronary artery bypass grafting in a cohort of patients was determined by each prioritisation strategy, and mean lifetime costs and quality adjusted life years (QALYs) were compared. Data sources Swedish Coronary Angiography and Angioplasty Registry (9935 patients with stable angina awaiting coronary artery bypass grafting and then followed up for cardiovascular events after the procedure for 3.8 years), and meta-analyses of prognostic effects (relative risks) of biomarkers. Results The observed risk of cardiovascular events while on the waiting list for coronary artery bypass grafting was 3 per 10 000 patients per day within the first 90 days (184 events in 9935 patients). Using a cost effectiveness threshold of 20 pound 000-30 pound 000 ((sic)22 000-(sic)33 000; $32 000-$48 000) per additional QALY, a prioritisation strategy using a risk score with estimated glomerular filtration rate was the most cost effective strategy (cost per additional QALY was andlt;410 pound compared with the Ontario urgency score). The impact on population health of implementing this strategy was 800 QALYs per 100 000 patients at an additional cost of 245 pound 000 to the National Health Service. The prioritisation strategy using a risk score with C reactive protein was associated with lower QALYs and higher costs compared with a risk score using estimated glomerular filtration rate. Conclusion Evaluating the cost effectiveness of prognostic biomarkers is important even when effects at an individual level are small. Formal prioritisation of patients awaiting coronary artery bypass grafting using a routinely assessed biomarker (estimated glomerular filtration rate) along with simple, routinely collected clinical information was cost effective. Prioritisation strategies based on the prognostic information conferred by C reactive protein, which is not currently measured in this context, or a combination of C reactive protein and estimated glomerular filtration rate, is unlikely to be cost effective. The widespread practice of using only implicit or informal means of clinically ordering the waiting list may be harmful and should be replaced with formal prioritisation approaches.

    Cost-effectiveness of ticagrelor in acute coronary syndromes2013Ingår i: Expert review of pharmacoeconomics & outcomes research, ISSN 1473-7167, E-ISSN 1744-8379, Vol. 13, nr 1, s. 9-18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ticagrelor is a reversibly binding oral P2Y(12) inhibitor, which belongs to a novel chemical class of antiplatelet agents named cyclopentyl-triazolo-pyrimidines. Ticagrelor administered with acetylsalicylic acid has been shown to reduce the rate of the composite end point of death from vascular causes, myocardial infarction or stroke without an increase in the rate of overall major bleeding compared with clopidogrel plus acetylsalicylic acid in patients with acute coronary syndromes. In addition to these clinical findings, it has been shown that the cost per quality-adjusted life year with ticagrelor is below the generally acceptable thresholds for cost-effectiveness compared with clopidogrel. Healthcare decision-makers need to consider the costs and cost-effectiveness when prioritizing treatments among scarce healthcare resources. This is of particular importance in cases similar to ticagrelor, where the novel treatment is expected to improve effectiveness at a higher acquisition cost. In this article, the authors review and discuss the health-economic evidence of ticagrelor.

    Ticagrelor treatment in patients with acute coronary syndrome is cost-effective in Sweden and Denmark2014Ingår i: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 48, nr 3, s. 138-147Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives. To evaluate the cost-effectiveness of treating patients with acute coronary syndromes (ACS) for 12 months with ticagrelor compared with generic clopidogrel in Sweden and Denmark. Design. Decision-analytic model to estimate lifetime costs, life-expectancy, and quality-adjusted life years (QALYs) with ticagrelor and clopidogrel. Event rates, healthcare resource use, and health-related quality of life during 12 months of therapy were estimated from the PLATelet inhibition and patient Outcomes (PLATO) trial. Beyond 12 months, quality-adjusted survival and costs were estimated conditional on events occurring during the 12 months of therapy. When available, country-specific data were employed in the analysis. Incremental cost-effectiveness ratios are presented from a healthcare perspective and a broader societal perspective including costs falling outside the healthcare sector in 2010 local currency. Results. The cost per QALY with ticagrelor compared with generic clopidogrel was SEK 25 022 and DKK 26 892 for Sweden and Denmark, respectively, from a healthcare perspective. The cost per QALY from a broader societal perspective was SEK 24 290 and DKK 25 051 for Sweden and Denmark, respectively. Conclusion. The cost per QALY of treating ACS-patients with ticagrelor compared with generic clopidogrel is below the conventional thresholds of cost-effectiveness in Sweden and Denmark.
