Objective: Pressure ulcers, following cancer and heart disease, are considered as the third most costly health problem. In addition to high cost of treatments, considerable time is spent on care for patients. This study tends to evaluate the therapeutic outcomes of reconstruction of pressure ulcer injuries by flap coatings. Methods: This study is prospective; 85 patients with pressure ulcer who referred to Taleghani Hospital in Kermanshah during 2015-2016 for treatment by muscular coating flaps were followed up 1 week and 3 months after discharge. A questionnaire based on main objectives of the project including demographic information, treatment complications, treatment outcome, reconstruction, number of flaps to assess the success of flap coating in patients was completed for each patient. Considering the 95% confidence level and the 9% accuracy, treatment success rate was 76%, with a minimum sample size of 85 in each group. Reconstruction was done again if the treatment was unsuccessful. Data was analyzed by SPSS software version 22. Results: The success rate of pressure ulcer reconstruction by coating flaps significantly increased after 1 week and 3 months (P<0.05, 50.6% and 90.5%, respectively). The success rate of pressure ulcer reconstruction by coating flaps significantly increased after 1 week and 3 months in terms of age, gender, and BMI (P<0.05). Conclusion: The success of pressure ulcer reconstruction increased by coating flaps after 3 months. Therefore, it is suggested that further studies be developed in the future. Second, this study did not have control group. Therefore, it is recommended to consider this in future studies.
