The Psychometric Properties of the Braden Scale to Assess Pressure Injury Risk in Acute Care: A Systematic Review.

AIM

To analyse existing knowledge on the psychometric properties of the Braden Scale when used within the acute care setting.

DESIGN

Systematic review and narrative synthesis.

METHODS

A database search was conducted in June 2023 and updated in February 2024, seeking studies testing the psychometric properties of the Braden scale in the acute care setting. Data were sourced from five electronic databases (CINAHL, EMBASE, MEDLINE, Scopus and Web of Science). Study selection, data extraction and assessment of risk of bias were completed, with two reviewers independently conducting each stage and an independent reviewer arbitrating discrepancies. Data were extracted using a customised template and synthesised narratively. Risk of bias was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

RESULTS

Thirty-seven studies met the inclusion criteria. Internal consistency was reported between 0.64 and 0.78 (Cronbach's alpha). Inter-rater reliability was high, reported as ranging from 0.946 to 0.964 (intra-class correlations) or 0.86 to 0.949 (Pearson's correlation). Most validity studies tested predictive validity with wide variances reported.

CONCLUSION

The Braden Scale is reliable for assessing the risk of PI in acute care, but the validity of the scale is variable. Further research investigating validity beyond predictive validity is required.

RELEVANCE TO CLINICAL PRACTICE

Nurses working in acute care can use the Braden Scale with confidence of scale reliability. However, validity is variable and warrants a cautious approach. The true value resides in the capacity to trigger recognition of pressure injury risk.

TRIAL REGISTRATION

The protocol was registered a priori with the International Prospective Register of Systematic Reviews PROSPERO ref: CRD42023407545.
