Many researches have shown that 95% of pressure ulcers are preventable. Prevention is far more cost-effective than the treatment. Therefore, prevention is the best strategy to reduce the pressure ulcer occurrence. It’s crucial that patients who are at risk are accurately identified before the appropriate measures can be implemented. The Braden Scale is used widely in various healthcare settings. The complete study process has shown it to have the highest predictive power. It’s easily understood and user-friendly. It only takes less than a minute to complete the assessment. As a result, the Braden Scale facilitates the healthcare professionals to accurately identify the risk and implement the necessary preventive actions in a timely manner.
The purpose of this prospective study design were to evaluate the validity of Braden Scale on ventilated patients. There were eighty subjects selected from a medical center in Taipei, Taiwan. The criteria were being ventilated more than 24 hours, stay longer than 24 hours, not receiving inotropic agents and free from pressure ulcers. The demographic information was collected and the Braden Scale was used. The data was analyzed by the statistical software SPSS version 20.0.
The data showed the optimal cut-off point for the Braden Scale in ventilated patients was 15 with sensitivity and specificity of 40% and 41.3%, respectively. The cumulative incidence was 6.25% (5/80) and incidence density was 0.30% (5/1,663). In this study, it indicated no direct relationship between pressure ulcer occurrence and characteristics of the subjects (p>0.05). However, based on the odds ratio (OR), the development of pressure ulcer on ventilated patients has a strong relationship to age, gender, cardiovascular disease, diabetes mellitus, hemodialysis, the length on ventilator and the cumulative scores of Braden Scale. These factors can be utilized as guidelines for clinical practitioners to identify patients at risk efficiently and initiate patient-centered care to eliminate the incidence of pressure ulcers.
Key words: ventilated patients, Braden Scale, cut-off point, incidence of pressure ulcer, risk factors of pressure ulcer
