Pressure Ulcer Prevention, Nursing Supervision Model, Supervisory BehaviorsAbstract
The purposes of this one-group quasi-experimental research were to compare the supervisory behaviors of nursing administrators and the competency of professional nurses in preventing pressure ulcers between before and after using a new nursing supervision model to prevent such pressure ulcers. The sample were composed of two groups: 1) 12 head nurses and sub-head nurses at Thung Song hospital, and 2) 52 registered nurses at Thung Song hospital in Nakhon Si Thammarat province who were all selected by simple random sampling. The research tools were: a) a nursing supervision model, which included supervision manual and nursing practice guideline on pressure ulcer prevention, b) a questionnaire on supervision behaviors of nursing administrators, and c) a questionnaire on competency of professional nurses in preventing pressure ulcers. Both questionnaires were validated by five experts. The content validity indexes of both tools were 0.80 and Cronbach 's alpha coefficient were 0.98 and 0.96, respectively. Data were analyzed by descriptive statistics, Wilcoxon-signed rank test, and paired t-test. The results were as follows.
1. After using the developed supervision model, nursing administrators perceived their supervisory behaviors at a high level and, indeed, the supervisory behaviors were significantly higher than before using the developed model (p<.001).
2. After using the developed nursing supervision model, professional nurses also reported their competency in preventing pressure ulcers at a high level. Lastly, the competency of professional nurses in preventing pressure ulcers after using the developed nursing supervision model were significantly higher than before using the developed supervision model (p<.001).
The nursing supervision model to prevent pressure ulcers should be continuously used and follow-up periodically in every 3 months, 6 months, and 1 year. Furthermore, the model should be applied to nursing care of patients.
