Popis: PURPOSE The purpose of this study was to compare the effect of pressure injuries on mortality, hospital length of stay, healthcare costs, and readmission rates in hospitalized patients. DESIGN A case-control study. SUBJECTS AND SETTING The sample comprised 5000 patients admitted to a tertiary hospital located in Seoul Korea; 1000 patients with pressure injuries (cases) were compared to 4000 patients who acted as controls. METHODS We retrospectively extracted clinical data from electronic health records. Study outcomes were mortality, hospital length of stay, healthcare costs, and readmission rates. The impact of pressure injuries on death and readmission was analyzed via multiple logistic regression, hospital deaths within 30 days were analyzed using the survival analysis and Cox proportional hazards regression, and impact on the length of hospitalization and medical costs were analyzed through a multiple linear regression. RESULTS Developing a pressure injury was significantly associated with an increased risk of in-hospital mortality (odds ratio [OR], 3.94; 95% confidence interval [CI], 2.91-5.33), 30-days in-hospital mortality (OR, 2.18; 95% CI, 1.59-3.00), and healthcare cost (β = 11,937,333; P < .001). Pressure injuries were significantly associated with an extended length of hospitalization (β = 20.84; P < .001) and length of intensive care unit (ICU) stay (β = 8.16; P < .001). Having a pressure injury was significantly associated with an increased risk of not being discharged home (OR, 5.55; 95% CI, 4.35-7.08), along with increased risks of readmission (OR, 1.30; 95% CI, 1.05-1.62) and emergency department visits after discharge (OR, 1.70; 95% CI, 1.29-2.23). CONCLUSIONS Development of pressure injuries influenced mortality, healthcare costs, ICU and hospital length of stay, and healthcare utilization following discharge (ie, readmission or emergency department visits). Hospital-level efforts and interdisciplinary approaches should be prioritized to develop interventions and protocols for pressure injury prevention.
