Predictive value of the Braden scale for hospital-acquired pressure injuries and the association with the prevention interventions
Introduction: Hospital-acquired pressure injuries (HAPI) are considered adverse events related to nursing care. As part of improving the quality of care, preventive nursing interventions such as screening and mobilization are essential. Objectives: To compare the predictive values of the Braden total score and the mobility dimension score on the development of HAPI. To measure the moderating effect of prevention interventions between the level of risk and the prevalence of HAPI. Methods: The design was correlational descriptive. A secondary analysis was done with routine data from electronics health records between March 1, 2016 and March 31, 2018. Descriptive statistics and univariable and multivariable logistic regression were performed. Results: HAPI prevalence among the 22,883 care episodes studied was 3.6%. The mobility score was predictive of the development of HAPI (OR=17.2, p < 0.01) as well as the total score (OR=13.9, p < 0.01). The mobilization interventions had a moderating effect when the interaction was considered low risk (OR=0.6, p < 0.01) and moderate risk (OR=0.5, p < 0.01) by Braden’s total score, but not for a high risk level. Discussion and conclusion: This study confirms the association between the development of HAPI and preventive interventions. It demonstrates the importance of using valid tools to screen for risk and implement mobilization interventions in order to have a positive impact on outcomes and thus improve the quality of care.
