The pressure injury prevalence and practice improvements (PIPPI) study: A multiple methods evaluation of pressure injury prevention practices in an acute-care hospital.

Pressure injuries are a significant problem for immobile patients in acute care and can have a profound impact on patients' health and well-being, putting pressure on healthcare systems and strain on the healthcare economy. Nurses play a pivotal role in preventing pressure injuries. A study using multiple methods was conducted to explore pressure injury prevention practices in four inpatient units within a tertiary-level Australian Hospital. Quantitative and qualitative methods were used to gather data across a 9-month period. Observations, audits, surveys and interviews were used to collect data across five time points. Statistical analysis of the quantitative data was undertaken, and thematic analysis was used to analyse qualitative data. Data were integrated using a realist evaluation framework. Ethical approval for the study was granted. The quantitative results demonstrated significant reductions in pressure injury prevalence from 11.5% at commencement to 4.8% at completion of the study. Hospital-acquired pressure injuries also reduced from 4.6% to 1.9%. These results were achieved even though nursing knowledge and attitudes did not increase during the study period. Three qualitative themes were identified: Making Nursing Care Visible, Understanding the 'Why' and Engagement is Key. This study demonstrates that pressure injuries can be prevented with improvements in nursing care processes. Nurses' knowledge and attitudes towards pressure injury prevention did not change throughout this study and further research is required on how nurses' knowledge and attitudes contribute towards pressure injury prevention practices.
