To determine the predictors of pressure injuries among residents living in Sri Lankan nursing homes.
A prospective multi-site longitudinal cohort study design.
Semi-structured observations and chart audits were used to gather data on 17 predictors of pressure injury from a consecutive sample of 210 residents (aged ≥ 60 years old) from nine nursing homes in Sri Lanka. Data were collected at baseline and followed up every week until the study endpoint: a new pressure injury or reaching the maximum 12 weeks of data collection, from July to October 2023. Validated semi-structured data collection forms and chart audits were utilised. Binary logistic regression was used to identify the predictors of pressure injuries. Generalised linear mixed models were used to assess the association between predictors and the development of new pressure injuries.
The cumulative incidence of pressure injuries was 17.1% (36/210) during the 12 weeks. The number of medical devices and baseline pressure injuries predicted the development of new pressure injuries. Each additional medical device increased the likelihood of developing a pressure injury by 2.3-fold, and individuals with a baseline pressure injury were 2.1 times more likely to develop a new pressure injury.
Multiple medical devices and baseline pressure injuries are predictors of pressure injury in older residents living in nursing homes.
This study provides evidence of pressure injury predictors among older residents living in nursing homes. Early identification of high-risk residents with an existing pressure injury and those with multiple medical devices is important for nurses and managers at nursing homes. Accurately assessing residents' risk of a pressure injury may result in implementing various preventive strategies that may ultimately help prevent future pressure injuries.

Preventing pressure injuries among nursing home residents is a significant challenge that necessitates understanding the barriers and facilitators from the perspective of staff. This qualitative study aimed to describe these factors within Sri Lankan nursing homes. Semi-structured interviews were conducted with 15 nursing home staff members from nine nursing homes in and near the Colombo district, Sri Lanka. The study was informed by the capability, opportunity, motivation, and behaviour model that guided both data collection and analysis. Data were analysed using content analysis. Using deductive coding based on capability, opportunity, and motivation, followed by inductive analysis, four primary categories emerged: focusing on skincare is foundational for pressure injury prevention, pressure injury knowledge is critical for prevention, pressure injury prevention is a low organisational priority, and overcoming challenges to enact pressure injury prevention. Key facilitators included access to skincare products, maintaining clean and dry skin, recognising risk factors, proactively managing risks, and understanding the broader implications of pressure injuries on residents and their families. Conversely, barriers encompassed limited training, varying staff support, inadequate resources, and the complexities of managing multiple tasks. This research highlights that enhancing knowledge and allocating resources effectively can improve the implementation of pressure injury prevention strategies in Sri Lankan nursing homes.
