Abstract
Pressure ulcers result in financial losses, including the cost of unnecessary medical expenses because of extended hospital stays, treatment, and examination. This was a retrospective, observational, methodological study to develop quality indicators related to pressure ulcer development and validate risk adjustment factors for pressure ulcer development. We performed a literature review to develop risk adjustment factors, and an expert group performed a content validity test. To validate risk adjustment factors for pressure ulcer development using electronic medical records, 127 patients admitted to a long-term care hospital in South Korea from June to September 2015 were enrolled in the study. Pressure ulcer risk factors were peripheral vascular disease, end-stage disease, past pressure ulcer history, high risk group for pressure ulcer development, fever, haemoglobin, and albumin (all P < 0.05); only albumin (odds ratio: 0.210, P < 0.001) was significantly associated with pressure ulcer development as an independent risk factor. Further research with a large sample size is needed for the validation of risk adjustment factors. Risk-adjusted quality indicators for pressure ulcer development can be used to evaluate the quality of nursing care and compare outcomes after preventive pressure ulcer care activities or between long-term care hospitals.
