The Braden Scale for Predicting Pressure Sore Risk
Nursing Research
|July 1, 1987
Summary
The Braden Scale effectively identifies patients at risk for pressure sores. It demonstrates high reliability and strong predictive validity, making it a valuable tool for healthcare professionals in preventing these injuries.
Area of Science:
- Nursing
- Clinical Assessment
- Patient Safety
Background:
- Pressure sores pose a significant risk to patient well-being and healthcare costs.
- Early identification of at-risk individuals is crucial for effective prevention strategies.
Purpose of the Study:
- To evaluate the reliability and predictive validity of the Braden Scale for Pressure Sore Risk.
- To establish the scale's sensitivity and specificity in identifying patients prone to pressure sores.
Main Methods:
- The Braden Scale, comprising six subscales, was assessed for content and construct validity.
- Three reliability studies were conducted with varying rater qualifications and locations.
- Two prospective studies evaluated the scale's predictive validity, sensitivity, and specificity.
Main Results:
- Reliability coefficients ranged from r = .83 to r = .99, with highest reliability observed among registered nurses (RNs).
- Using a cut-off score of 16, the scale achieved 100% sensitivity in both predictive validity studies.
- Specificity ranged from 64% to 90%, indicating a strong ability to correctly identify those not at risk.
Conclusions:
- The Braden Scale demonstrates highly satisfactory reliability, particularly when used by RNs.
- The scale offers superior sensitivity and specificity compared to previously reported instruments for pressure sore risk assessment.
- The Braden Scale is a validated and effective tool for the early identification and prevention of pressure sores.
