Evaluation of a multifactorial approach to reduce the prevalence of pressure injuries in regional Australian acute inpatient care settings.

Abstract

The aim of the study was to compare the changes in the prevalence of pressure injuries from 2008 to 2014 in relation to staff behaviour in acute/subacute inpatient care settings. In 2008, the large regional health district Hunter New England Local Health District implemented an initiative called the Crystal Model which resulted in changes in their policy and an e-learning education program for all nursing staff. A retrospective cross sectional study compared data from the 2008, 2010 and 2014 point prevalence surveys of PI in acute services. These were collected as part of an annual pressure injury prevention and management quality audit for adult inpatients. The total number of participants included 1407 participants in 2008, 1331 participants in 2010 and 1199 participants in 2014. From 2008 to 2014 there was a 15.7% decrease in percentage of patients with hospital-acquired pressure injuries and the percentages of each stage of pressure of injury 1-4 decreased. From 2008 to 2014 the completion and documentation of risk assessment, the documentation of repositioning and the implementation of pressure-relieving equipment increased. A multifactorial model can reduce the prevalence of pressure injuries in acute inpatient settings. The theories of knowledge translation and the modified Theory of Planned Behaviour can be utilised to analyse changes in health professionals habituated pressure injury prevention practice.
