Background & Aim: Pressure ulcers are one of the indicators of the quality of nursing and health care. Nurses, as one of the main members of the health team, play an important role in the prevention of pressure ulcer in health care centers. Therefore, this study aimed to determine the knowledge, attitude, and practice of nurses in preventing pressure ulcer. Materials & Methods: This descriptive cross-sectional study was conducted in 2018. Through complete enumeration, all the employed intensive care unit nurses in the educational centers of Iran University of Medical Sciences were studied. Out of the 328 questionnaires, 308 questionnaires were completed by the participants. For data collection, Pieper Pressure Ulcer Knowledge Test (PPUKT) and Beeckman et al’s attitude toward pressure ulcer questionnaire were used. Data were analyzed by SPSS software version 16, using independent t-test, Chi-square, Fisher’s exact, and one-way ANOVA. Results: According to the results, the mean score of knowledge and attitude of nurses regarding the prevention of pressure ulcer were 63.10 ± 47.31, 39.39 ± 10.22, respectively. The knowledge and attitude of the majority of nurses, regarding the prevention of pressure ulcer was at an undesirable level. Different groups of gender, background of continuous education, work experience, and experience in ICU had a significant difference in knowledge score. There were significant differences between different groups of gender, working hours per week, work experience, and work experience in ICU in terms of attitude score. Conclusion: Considering the undesirable level of knowledge and attitude of nurses about the standards of prevention of pressure ulcers and the importance of improving the safety of patients admitted to the intensive care unit, it is suggested to develop appropriate educational planning to improve the knowledge and attitude of health care providers, especially nurses, in the area of prevention of pressure ulcer.

Pressure ulcer is a signifcant problem in elderly and critically ill patients, causing pain, decreasing quality of life and leading to prolonged hospital stay. Treatment of pressure ulcer to improve health status is a cost-effective approach. So, preventing the ulcers will be economical. Pressure ulcer is considered as a damage or necrosis of skin and its layers, which happens when there is a considerable pressure over the tissues. If the capillary arterie's pressure reaches 70 mmHg (2 times more than the normal pressure) pressure ulcer happens and depending on the depth of the ulcer, will be divided into 4 stages. The most important point for preventing the ulcers is reducing the pressure. Patients should be repositioned to relieve or minimize the tissue pressure. Considering the type of the ulcer, the necessary treatment (dressing, Antibiotic Therapy, debridement or surgery) should be performed.

Introduction: Bed sore is an important complication of operation. Long immobility, hypotension and hypothermia in perioperative period predispose patients to bed sore. The prevention of bed sore is a priority in caring for immobilized patients and different methods have been used for this purpose. Hydrocolloid dressing is one of these methods. Materials and Methods: This study is a quasi-experimental research. Subjects consisted of 60 patients aged 40-70 years who had eligibility criteria for this study. Subjects were selected with convenience sampling and randomly allocated to two 30-patient groups (experimental and control). In experimental group, hydrocolloid dressing was used before surgery. No procedure was performed for control group. After surgery sacral area was examined on three occasions to detect bed sore: immediately, 24 and 48 hours after surgery. The data were collected by demographic questionnaire and staging bed sore checklist and analyzed by SPSS statistic program and use of descriptive methods such as Chi square, Fisher exact test, t test, ANOVA and least significant difference (LSD). Results: Incidence of bed sore was 13.3% in experimental group and %36.7 in control group. Chi square test showed significant difference between incidence of bed sore in two groups (p=0.03). Incidence of bed sore in two groups had no relationship with respect to gender and number of grafts. There was a significant relationship between bed sore and age, body mass index and duration of hypothermia, immobility and cardiopulmonary bypass (p
