Outline of Final Research Achievements

The presence of pressure ulcers may affect patient discharge destination; however, no related large-scale survey has been conducted in Japan. In this retrospective observational cohort study, Japanese Diagnosis Procedure Combination database was used. We assessed 340,124 inpatients aged 65 years or older admitted from their own homes. To examine the association between pressure ulcer status (none, healed, healing, stable, worsened, or developed) and discharge to home, we used multivariable logistic regressions. The prevalence of pressure ulcer on admission was 1.9%; the overall proportion of hospital-acquired pressure ulcers was 1.1%. With reference to the group without pressure ulcers, poor pressure ulcer status (developed < worsened < stable < healing < healed) was significantly associated with decreased probability of discharge to home. In conclusion, pressure ulcer status may have a great impact on hospital discharge destination among elderly patients admitted from their own homes.
