ABSTRACT
BACKGROUND: Hospital-based Special Care Units (SCU) for dementia show promise as effective models of care. However, limited research describes hospital-wide benefits.
OBJECTIVE: To describe patient-level outcomes and hospital service-level outcomes of a SCU.
DESIGN: Pre-post analyses of SCU-patient data and hospital service-unit incident report data.
SETTING, PARTICIPANTS: 2-years of SCU-patient admissions and 4-years of hospital incident-reports from four medical wards (2-years pre-post SCU).
METHODS: Admission and discharge severity of SCU-patients’ behaviour was prospectively measured by specialist SCU nurses. One-year hospitalisation rates, length-of-stay, diagnosis and patient demographics were retrospectively obtained from medical records. Hospital service-unit data included 4 years of monthly incident report rates for falls, pressure injury and occupational violence (OV) across four medical wards. Analysis of count data used Poisson and Negative Binomial Regression models.
RESULTS: 121 SCU admissions involved 107 unique patients. Median SCU LoS was 23 days (interquartile range [IQR], 13-50), and stabilisation of behaviour severity took 11 days (IQR 6-12). Barriers to discharge related to substitute decision-making and care facility availability. After SCU discharge, yearly hospitalisation rates for ‘all-reasons’ decreased by 68% (Incident Rate Ratio [IRR], 0.32, 95% CI, 0.23-0.43), and 83% for behaviour-related admissions (IRR 0.17, 95% CI, 0.11-0.28). For hospital service-unit outcomes, falls-per-month decreased by 21% (IRR 0.79, 95% CI 0.64-0.99) after SCU implementation and OV by 26% (IRR, 0.74, 95% CI 0.59-0.94).
CONCLUSIONS: A hospital-based SCU reduced hospital health service demand through decreased SCU-patient readmissions and was associated with decreased falls and OV rates across hospital medical wards.
