    Role of histamine release in nonspecific vasodilatation during anodal and cathodal iontophoresis2004Inngår i: Microvascular research, ISSN 0026-2862, Vol. 67, nr 2, s. 192-196Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Nonspecific vasodilatation during iontophoresis is an important confounding factor in experimental pharmacology. In this investigation, we studied the involvement of sensory nerves and histamine-related reactions in causing nonspecific vasodilatation in a model of anodal and cathodal iontophoresis of sodium chloride. Firstly, we applied a mixture of local anesthetic (EMLA) cream to confirm its suppressive effect on nonspecific vasodilatation and to measure its efficacy in three different dosages (duration: 1, 2, and 3 h). We then investigated the role of histamine in nonspecific vasodilatation by giving an oral antihistamine drug (cetirizine) to subjects who had and had not been given EMLA. We found substantial suppression of the nonspecific vasodilatation in all EMLA-treated groups (all dosages) compared with untreated controls (with suppression rates of 60–65%). Dosage had no significant effect. A further suppression of nonspecific vasodilatation was seen after oral cetirizine during anodal and cathodal iontophoresis in both EMLA-treated and untreated groups. The antihistamine effect was most pronounced during anodal iontophoresis. These results suggest a histaminergic increase in perfusion that may be independent of neurogenic mechanisms and depend on polarity (anode or cathode). Local nerve blocks (EMLA) together with cetirizine may therefore be used to reduce nonspecific vasodilatation in both anodal and cathodal iontophoresis.

    Triage performance of Swedish physicians using the ATLS algorithm in a simulated mass casualty incident: a prospective cross-sectional survey2013Inngår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, Vol. 21, nr 90Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: In a mass casualty situation, medical personnel must rapidly assess and prioritize patients for treatment and transport. Triage is an important tool for medical management in disaster situations. Lack of common international and Swedish triage guidelines could lead to confusion. Attending the Advanced Trauma Life Support (ATLS) provider course is becoming compulsory in the northern part of Europe. The aim of the ATLS guidelines is provision of effective management of single critically injured patients, not mass casualties incidents. However, the use of the ABCDE algorithms from ATLS, has been proposed to be valuable, even in a disaster environment. The objective for this study was to determine whether the mnemonic ABCDE as instructed in the ATLS provider course, affects the ability of Swedish physician's to correctly triage patients in a simulated mass casualty incident.Methods: The study group included 169 ATLS provider students from 10 courses and course sites in Sweden; 153 students filled in an anonymous test just before the course and just after the course. The tests contained 3 questions based on overall priority. The assignment was to triage 15 hypothetical patients who had been involved in a bus crash. Triage was performed according to the ABCDE algorithm. In the triage, the ATLS students used a colour-coded algorithm with red for priority 1, yellow for priority 2, green for priority 3 and black for dead. The students were instructed to identify and prioritize 3 of the most critically injured patients, who should be the first to leave the scene. The same test was used before and after the course.Results: The triage section of the test was completed by 142 of the 169 participants both before and after the course. The results indicate that there was no significant difference in triage knowledge among Swedish physicians who attended the ATLS provider course. The results also showed that Swedish physicians have little experience of real mass casualty incidents and exercises.Conclusion: The mnemonic ABCDE doesn't significantly affect the ability of triage among Swedish physicians. Actions to increase Swedish physicians' knowledge of triage, within the ATLS context or separately, are warranted.

    Weak and strong points in training of prehospital command and control. Are results possible to measure?2008Inngår i: International Review of the Armed Forces Medical Services / Revue internationale des services de santé des forces armées, ISSN 0259-8582, Vol. 81, nr 3, s. 131-134Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [fr]

    Dans l'évaluation des entraînements et des exercices militaires, les points faibles sont souvent exprimés en termes généraux. C'est pourquoi il est difficile de savoir précisément ce qui nécessite une amélioration. Les leçons qui devraient en être tirées ont rarement été observées. Il est nécessaire d'avoir une approche méthodique et quantitative de ce problème et des outils sont maintenant disponibles. Les indicateurs de performance ont déjà été testés sur un exercice militaire, et se sont avérés applicables. La présente étude s'est intéressée de plus près à ces indicateurs de performance. Les critères mis en place pour les usages civils devraient pouvoir être utilisés dans dix cas sur onze. L'indicateur de performance où l'objectif n'est le plus souvent pas atteint est de pouvoir évacuer le premier patient en moins de 15 minutes. Le prochain pas est d'appliquer ces indicateurs à l'entraînement militaire de base, aux entraînements officiels de préparation aux missions ainsi qu'aux exercices réalisés dans la zone de mission.

    Simulation-assisted burn disaster planning2013Inngår i: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 39, nr 6, s. 1122-1130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of the study was to evaluate the Swedish medical systems response to a mass casualty burn incident in a rural area with a focus on national coordination of burn care. Data were collected from two simulations of a mass casualty incident with burns in a rural area in the mid portion of Sweden close to the Norwegian border, based on a large inventory of emergency resources available in this area as well as regional hospitals, university hospitals and burn centres in Sweden and abroad. The simulation system Emergo Train System (R) (ETS) was used and risk for preventable death and complications were used as outcome measures: simulation I, 18.5% (n = 13) preventable deaths and 15.5% (n = 11) preventable complications; simulation II, 11.4% (n = 8) preventable deaths and 11.4% (n = 8) preventable complications. The last T1 patient was evacuated after 7 h in simulation I, compared with 5 h in simulation II. Better national coordination of burn care and more timely distribution based on the experience from the first simulation, and possibly a learning effect, led to a better patient outcome in simulation II. The experience using a system that combines both process and outcome indicators can create important results that may support disaster planning.

    Performance indicators for initial regional medical response to major incidents: a possible quality control tool2012Inngår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, E-ISSN 1757-7241, Vol. 20, nr 81Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    Timely decisions concerning mobilization and allocation of resources and distribution of casualties are crucial in medical management of major incidents. The aim of this study was to evaluate documented initial regional medical responses to major incidents by applying a set of 11 measurable performance indicators for regional medical command and control and test the feasibility of the indicators.

    Methods

    Retrospective data were collected from documentation from regional medical command and control at major incidents that occurred in two Swedish County Councils. Each incident was assigned to one of nine different categories and 11 measurable performance indicators for initial regional medical command and control were systematically applied. Two-way analysis of variance with one observation per cell was used for statistical analysis and the post hoc Tukey test was used for pairwise comparisons.

    Results

    The set of indicators for regional medical command and control could be applied in 102 of the130 major incidents (78%), but 36 incidents had to be excluded due to incomplete documentation. The indicators were not applicable as a set for 28 incidents (21.5%) due to different characteristics and time frames. Based on the indicators studied in 66 major incidents, the results demonstrate that the regional medical management performed according to the standard in the early phases (1–10 min after alert), but there were weaknesses in the secondary phase (10–30 min after alert). The significantly lowest scores were found for Indicator 8 (formulate general guidelines for response) and Indicator 10 (decide whether or not resources in own organization are adequate).

    Conclusions

    Measurable performance indicators for regional medical command and control can be applied to incidents that directly or indirectly involve casualties provided there is sufficient documentation available. Measurable performance indicators can enhance follow- up and be used as a structured quality control tool as well as constitute measurable parts of a nationally based follow-up system for major incidents. Additional indicators need to be developed for hospital-related incidents such as interference with hospital infrastructure.

    Quality control in disaster medicine training: Initial regional medical command and control as an example2010Inngår i: American journal of disaster medicine, ISSN 1932-149X, Vol. 5, nr 1, s. 35-40Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: The aim of this study was to show the possibility to identify what decisions in the initial regional medical command and control (IRMCC) that have to be improved. DESIGN: This was a prospective, observational study conducted during nine similar educational programs for regional and hospital medical command and control in major incidents and disasters. Eighteen management groups were evaluated during 18 standardized simulation exercises. MAIN OUTCOME MEASURE: More detailed and quantitative evaluation methods for systematic evaluation within disaster medicine have been asked for. The hypothesis was that measurable performance indicators can create comparable results and identify weak and strong areas of performance in disaster management education and training. Methods: Evaluation of each exercise was made with a set of 11 measurable performance indicators for IRMCC. The results of each indicator were scored 0, 1, or 2 according to the performance of each management group. RESULTS: The average of the total score for IRMCC was 14.05 of 22. The two best scored performance indicators, No 1 "declaring major incident" and No 2 "deciding on level of preparedness for staff" differed significantly from the two lowest scoring performance indicators, No 7 "first information to media" and No 8 "formulate general guidelines for response." CONCLUSION: The study demonstrated that decisions such as "formulating guidelines for response and "first information to media" were areas in initial medical command and control that need to be improved. This method can serve as a quality control tool in disaster management education programs.

    Gastrointestinal microcirculation and cardiopulmonary function during experimentally increased intra-abdominal pressure2009Inngår i: Critical Care Medicine, ISSN 0090-3493, E-ISSN 1530-0293, Vol. 37, nr 1, s. 230-239Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: The aim of this study was to assess gastric, intestinal, and renal cortex microcirculation parallel with central hemodynamics and respiratory function during stepwise increase of intra-abdominal pressure (IAP).

    Design: Prospective, controlled animal study.

    Setting: Research laboratory, University Hospital.

    Subjects: Twenty-six anesthetized and mechanically ventilated pigs.

    Interventions: Following baseline registrations, CO2 peritoneum was inflated (n = 20) and IAP increased stepwise by 10 mm Hg at 10 mins intervals up to 50 mm Hg and subsequently exsufflated. Control animals (n = 6) were not insufflated with CO2.

    Measurements and Main Results: The microcirculation of gastric mucosa, small bowel mucosa, small bowel seromuscular layer, colon mucosa, colon seromuscular layer, and renal cortex were selectively studied at all pressure levels and after exsufflation using a four-channel laser Doppler flowmeter (Periflex 5000, Perimed). Central hemodynamic and respiratory function data were registered at each level and after exsufflation. Cardiac output decreased significantly at IAP levels above 10 mm Hg. The microcirculation of gastric mucosa, renal cortex and the seromuscular layer of small bowel and colon was significantly reduced with each increase of IAP. The microcirculation of the small bowel mucosa and colon mucosa was significantly less affected compared with the serosa (p < 0.01).

    Conclusions: Our animal model of low and high IAP by intraperitoneal CO2-insufflation worked well for studies of microcirculation, hemodynamics, and pulmonary function. During stepwise increases of pressure there were marked effects on global hemodynamics, respiratory function, and microcirculation. The results indicate that intestinal mucosal flow, especially small bowel mucosal flow, although reduced, seems better preserved in response to intra-abdominal hypertension caused by CO2-insufflation than other intra-abdominal microvascular beds.

    Increased transmucosal uptake of E. coli K12 in porcine small bowel following experimental short term abdominal compartment syndrome2009Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Background: Abdominal compartment syndrome (ACS) may lead to bacterial translocation and possibly be of importance for development of multiorgan failure. However, the underlying mechanisms have not been fully elucidated. In a porcine model we recently demonstrated preserved intestinal mucosal blood flow during experimental short duration ACS. In the present study we used the same model to determine mucosal barrier function and morphology in the small bowel and colon of pigs before and after short term ACS.

    Methods: The study comprised 12 anaesthetized pigs exposed to experimental ACS and 6 control animals. Via laparotomy, samples of small bowel and colon were taken out for studies before short term ACS, where the abdomen was inflated with CO2 and IAP was increased stepwise by 10 mm Hg at 10-minute intervals up to 50 mm Hg, and again 10 minutes after exsufflation. Mucosal microcirculation was measured by laser Doppler flowmetry, and mucosal tissues were mounted in modified Ussing chambers for assessment of barrier function (E. coli K12 uptake and 51Cr-EDTA permeability). Specimens were also fixed in formaldehyde, stained with eosin-hematoxylin and evaluated blindly using an 8-grade scale for assessment of mucosal damage.

    Results: Transmucosal passage of E. coli was three-fold increased in the small bowel after ACS (22.6 [18.2 – 54.4] units) vs. baseline (8.1 [2.0 – 13.9]; P< 0.050) with a significant correlation to alterations of mucosal microcirculation. In the colon bacterial passage was unchanged, whereas 51Cr-EDTA permeability after ACS increased to 181% of baseline (P<0.05) and was correlated to significant mucosal histopathological changes (P<0.03).

    Conclusion: Short term ACS with reperfusion induced significant dysfunction of the intestinal mucosal barrier. The response patterns concerning barrier dysfunction differed between small bowel and colonic mucosa, with increased bacterial passage and paracellular permeability, respectively.

    Multipel Small Bowel Ligation Compared to Conventional Primary Repair after Abdominal Gunshot Wound with Haemorrhagic Shock2009Inngår i: Scandinavian Journal of Surgery, ISSN 1457-4969, E-ISSN 1799-7267, Vol. 98, nr 1, s. 41-47Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aims: The aim of this study was to evaluate the effects of early rapid control of multiple bowel perforations on cardiovascular function in combined abdominal missile trauma and haernorrhagic shock compared with conventional surgery.

    Methods: Eighteen anesthetised pigs were injured with a standardised abdominal missile trauma. The animals were bled to a mean arterial pressure of 50 mm Hg for 30 minutes, after which they were resuscitated and had laparotomy. They were divided into conventional surgery group (n=9) with primary resection and anastomosis of bowel injuries and early rapid multiple bowel ligation group (n=9). Repeated measurement analysis of variance was used for analysis.

    Results: There was profound hypotension, reduced cardiac output, increased vascular resistance and lactic acidaemia in both groups. Lactic acidaemia persisted longer in the early rapid multiple bowel ligation group. There were no significant differences in mean arterial pressure, cardiac output, stroke volume or systemic vascular resistance between the groups. The mean operation time was significantly shorter in the early rapid multiple bowel ligation group (13.3 (1.5) (SEM) minutes, compared with 116.4 (1.74) (SEM) minutes in the conventional surgery group, p = <0.001).

    Conclusions: Damage control principles have shortened the operating time in our model but did not improve the cardiovascular function and caused more lactic acidaemia than conventional repair.

    Performance indicators as quality control for testing and evaluating hospital management groups: a pilot study.2006Inngår i: Prehospital and Disaster Medicine, ISSN 1049-023X, E-ISSN 1945-1938, Vol. 21, nr 6, s. 423-426Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: An important issue in disaster medicine is the establishment of standards that can be used as a template for evaluation. With the establishment of standards, the ability to compare results will improve, both within and between different organizations involved in disaster management.

    OBJECTIVE: Performance indicators were developed for testing in simulations exercises with the purpose of evaluating the skills of hospital management groups. The objective of this study is to demonstrate how these indicators can be used to create numerically expressed results that can be compared.

    METHODS: Three different management groups were tested in standardized simulation exercises. The testing took place according to the organization's own disaster plan and within their own facilities. Trained observers used a pre-designed protocol of performance indicators as a template for the evaluation.

    RESULTS: The management group that scored lowest in management skills also scored lowest in staff skills. CONCLUSION: The use of performance indicators for evaluating the management skills of hospital groups can provide comparable results in testing situations and could provide a new tool for quality improvement of evaluations of real incidents and disasters.

    Improved Staff Procedure Skills Lead to Improved Management Skills: An Observational Study in an Educational Setting2009Inngår i: Prehospital and Disaster Medicine, ISSN 1049-023X, E-ISSN 1945-1938, Vol. 24, nr 5, s. 376-379Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Good staff procedure skills in a management group during incidents and disasters are believed to be a prerequisite for good management of the situation. However, this has not been demonstrated scientifically. Templates for evaluation results from performance indicators during simulation exercises have previously been tested. The aim of this study was to demonstrate the possibility that these indicators can be used as a tool for studying the relationship between good management skills and good staff procedure skills.

    Hypothesis: Good and structured work (staff procedure skills) in a hospital management group during simulation exercises in disaster medicine is related to good and timely decisions (good management skills).

    Methods: Results from 29 consecutive simulation exercises in which staff procedure skills and management skills were evaluated using quantitative measurements were included. The statistical analysis method used was simple linear regression with staff procedure skills as the response variable and management skills as the predictor variable.

    Results: An overall significant relationship was identified between staff pro-cedure skills and management skills (p ≤0.05).

    Conclusions: This study suggests that there is a relationship between staff procedure skills and management skills in the educational setting used. Future studies are needed to demonstrate if this also can be observed during actual incidents.

    Performance indicators - from theory to implementation: one method of scientific approach to disaster medicine2009Inngår i: Urgence Pratique, ISSN 1244-1791, Vol. 93, s. 41-44Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    The objective of this paper is to demonstrate a possible tool for the use of a quantitative research method that can be applied in disaster medicine.

    Method: Stepwise, using the technique of concept and process modelling, key processes in forms of performance indicators for command and control at disaster and major incidents were identified. A standard was linked to each indicator. Based in these indicators, an educational program was developed. In this program results from examinations were expressed in numbers and can thereby allow statistical methods to be applied.

    Results: Application of this model on prehospital command and control demonstrated weak and strong points. The method has been implemented in 13 out 21 regions and is used as a quality control tool.

    Conclusions: The use of performance indicators developed by using results from modelling processes could possibly serve as a tool for conducting quantitative research in disaster medicine.

    A new system for transmission of on-line information from scene of accident and ambulances to hospitals2003Inngår i: International Journal of Disaster Medicine, ISSN 1503-1438, Vol. 1, nr 2, s. 127-131Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. The 'Swede information system' was introduced in a county with approximately 450,000 inhabitants in April 2000. The implementation of this information system, intended to be operative in major incidents and disasters, has included the introduction of new technologies as well as new standard operating procedures for both ambulance crews and hospital staff. The objective of this study was to see how this information system with digitally mediated transmission was used as a daily routine during a 2-month period, 1 year after its introduction. Methods. The Swede information system sends on-line information from ambulances to emergency wards in the county. The technique used is a LAN (local area net) for communication within the site of the accident, Mobitex® from the ambulances to a data server and from this by Internet to the hospitals. During March and April 2001 all events when an ambulance was dispatched were recorded. All cases when the system was used to notify the receiving hospital were recorded as well as all cases when the ambulance crew alerted the hospital through the alert function. All technical problems and any period of time when the system was 'out of use' were noted. Results. During the period of the study, the system was successfully used to transfer data from the scene to hospital in a total of 3353 missions, including transport of a patient from the scene to an emergency department. Of these, in 150 transports the transferred data served as a base for immediate support on arrival at the hospital that was of critical importance for primary management in the hospital. In all, 2883 different kinds of medical data were transmitted. The local help-desk was notified of problems with the system on 11 occasions; six of these were technical problems and the rest were user-related. The IS Swede system was not operational during parts of 3 days (<5%) of the time. Conclusions. Despite the introduction of new equipment and new standard operating procedures, IS Swede was accepted within the organization to a degree which could be considered operational in major incidents. Technical problems with IS Swede caused only minor disturbances during the study period.

    Comparison of an on-line information system with a conventional ambulance file system regarding the retrieval of information after missions2005Inngår i: International Journal of Disaster Medicine, ISSN 1503-1438, Vol. 3, nr 1-4, s. 37-40Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: To determine if an on-line information system is superior to a conventional ambulance file system regarding the possibility of retrieving information as follow-up in daily use and also with reference to disaster situations.

    Materials and methods: The study was designed as a prospective study where two systems that have been operational for several years were compared. One system was a system primarily built for on-line registration and the other a conventional ambulance file system.

    Results: In all aspects data regarding ambulance missions and patients were more thoroughly registered in the conventional file system. Also data were easier to retrieve with less time consumption compared to the on-line system.

    Conclusion: The on-line information system studied was less accurate for storing and retrieving information than a conventional ambulance file system. Thus, more technical development is needed before this on-line system can be recommended for use in major incidents or disasters.

    Performance indicators for major incident medical management: a possible tool for quality control?2004Inngår i: International Journal of Disaster Medicine, ISSN 1503-1438, Vol. 2, nr 1-2, s. 52-55Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: The objective was to determine the outcome when applying a set of proposed performance indicators on previously published reports from major incidents.

    Methods: A set of 20 different performance indicators were proposed. These indicators were applied to 13 reports from major incidents issued by the KAMEDO organization.

    Results: The most frequently reported problems were command and control at the scene (11/13) followed by communication and command and control at the strategic level. In 25% of the published reports there was enough information available to apply the performance indicators, and in these the goal and/or objective was met in 67%.

    Conclusion: Performance indicators for the medical management of major incidents and disaster can to a limited extent be applicable to retrospective studies. Performance indicators might be a tool for evaluating the medical response if reports are made with a different template. Further studies are needed in order to validate which indicators to use.

    Performance indicators for prehospital command and control in training of medical first responders2004Inngår i: International Journal of Disaster Medicine, ISSN 1503-1438, Vol. 2, nr 3, s. 89-92Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of this study was to determine if a set of performance indicators could indicate what part of medical command and control needs to be improved in a training concept designed for medical officers at major incidents. A set of 11 different performance indicators previously proposed was used as a template when examining ambulance staff in medical command and control. The results were graded 0 to 2 where 0 = not acceptable, 1 = partially correct and 2 = correct. A total of 46 examinations comprising more than 200 students was included. Performing a correct second report (score 1.15), the ability to establish general guidelines for medical response (score 1.20), setting level of medical ambition (score 1.24) and informing media (score 1.33) had significantly lower scores than the other performance indicators. Performance indicators for medical management in a major incident can be used in a training setting for identifying areas that need improvement.

    Staff procedure skills in management groups during exercise in disaster medicine2006Inngår i: Prehospital and Disaster Medicine, ISSN 1049-023X, E-ISSN 1945-1938, Vol. 22, nr 4, s. 318-324Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: In stressful situations such as the management of major incidents and disasters, the ability to work in a structured way is important. Medical management groups initially are formed by personnel from different operations that are on-call when the incident or disaster occurs.

    OBJECTIVE: The aim of this study was to test if performance indicators for staff procedure skills in medical management groups during simulations could be used as a quality control tool for finding areas that require improvement.

    METHODS: A total of 44 management groups were evaluated using performance indicators in which results could be expressed numerically during simulations.

    RESULTS: The lowest scores were given to documentation and to the introduction of new staff members. The highest score was given the utilization of technical equipment.

    CONCLUSIONS: Staff procedure skills can be measured during simulations exercises. A logging system may lead to enhancing areas requiring improvement.

    Can performance indicators be used for pedagogic purposes in disaster medicine training?2009Inngår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, E-ISSN 1757-7241, Vol. 17, nr 15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Although disaster simulation trainings were widely used to test hospital disaster plans and train medical staff, the teaching performance of the instructors in disaster medicine training has never been evaluated. The aim of this study was to determine whether the performance indicators for measuring educational skill in disaster medicine training could indicate issues that needed improvement.

    METHODS: The educational skills of 15 groups attending disaster medicine instructor courses were evaluated using 13 measurable performance indicators. The results of each indicator were scored at 0, 1 or 2 according to the teaching performance.

    RESULTS: The total summed scores ranged from 17 to 26 with a mean of 22.67. Three indicators: 'Design', 'Goal' and 'Target group' received the maximum scores. Indicators concerning running exercises had significantly lower scores as compared to others.

    CONCLUSION: Performance indicators could point out the weakness area of instructors' educational skills. Performance indicators can be used effectively for pedagogic purposes.
