Abstract [en]

Aim. This paper reports a study to identify risk factors associated with pressure ulcer development among a mixed group of adult patients undergoing surgery. Background. Few studies have been carried out with patients undergoing surgery to assess the risk of pressure ulcer development, and so there is a little knowledge of the risk factors for this group. However, studies among non-surgical patients have shown that nutritional predictors such as low serum albumin level and low body mass index (BMI) are of great importance. An additional predictive factor may be low blood pressure. It is important to study these predictors further among patients undergoing surgery, using techniques such as multiple regression techniques, designed to identify the most important predictors for pressure ulcer development. Methods. A prospective comparative study was carried out in 1996-1998 with 286 adult patients undergoing surgical treatment. The data were collected from patient records by Registered Nurses preoperatively, for seven days postoperatively and thereafter once a week for up to 12 weeks. Perioperative data were also collected. The Risk Assessment Pressure Sore Scale was used, and data were collected on general physical condition, activity, mobility, moisture, food intake, fluid intake, sensory perception, friction and shear, body temperature and serum albumin. Results. Forty-one (14.3%) patients developed pressure ulcers during the observation period. The most common type was non-blanchable erythema. Those who developed pressure ulcers were significantly older, weighed less, and had a lower BMI and serum albumin. More women than men developed pressure ulcers. Risk factors identified in multiple stepwise regression analyses were female gender, American Society of Anaesthesiologists (ASA) status or New York Heart Association (NYHA) status and food-intake. Conclusion. Special attention, with regard to risk of pressure ulcer development, should be paid to patients undergoing surgery who have low ASA or NYHA scores, low food intake and/or are women. © 2005 Blackwell Publishing Ltd.

Abstract [en]

Background. The ability to assess the risk of a patient developing pressure sores is a major issue in pressure sore prevention. Risk assessment scales should be valid, reliable and easy to use in clinical practice.

Aim.  To develop further a risk assessment scale, for predicting pressure sore development and, in addition, to present the validity and reliability of this scale.

Methods. The risk assessment pressure sore (RAPS) scale, includes 12 variables, five from the re-modified Norton scale, three from the Braden scale and three from other research results. Five hundred and thirty patients without pressure sores on admission were included in the study and assessed over a maximum period of 12 weeks. Internal consistency was examined by item analysis and equivalence by interrater reliability. To estimate equivalence, 10 pairs of nurses assessed a total of 116 patients. The underlying dimensions of the scale were examined by factor analysis. The predictive validity was examined by determination of sensitivity, specificity and predictive value.

Results.  Two variables were excluded as a result of low item–item and item–total correlations. The average percentage of agreement and the intraclass correlation between raters were 70% and 0·83, respectively. The factor analysis gave three factors, with a total variance explained of 65·1%. Sensitivity, specificity and predictive value were high among patients at medical and infection wards.

Conclusions.  The RAPS scale is a reliable scale for predicting pressure sore development. The validity is especially good for patients undergoing treatment in medical wards and wards for infectious diseases. This indicates that the RAPS scale may be useful in clinical practice for these groups of patients. For patients undergoing surgical treatment, further analysis will be performed.
