Abstract
BACKGROUND: Norwegian Municipal Inpatient Acute Care (MIPAC) services were established as part of the 2012 Coordination Reform. The intention was to prevent unnecessary hospital admissions by redirecting and maintaining less urgent patients at the primary care level, which provides inpatient acute healthcare services closer to patients' home. However, the role MIPAC plays in the patient trajectory and how trajectories vary across different units and settings is less clear. OBJECTIVE: Therefore, this study aimed to (1) describe the general patient transfer trajectories for MIPAC patients and (2) examine facility and regional variations in MIPAC patients' sources of admission and discharge destinations. DESIGN: A cross-sectional study using aggregated register data. METHODS: The study involved 36 662 admissions across 185 MIPAC units in 2019. Descriptive statistics were used to describe patient transfer trajectories, and a random-effects multinomial logistic model was applied to assess the association between facility and regional factors and patients' admission sources and discharge destinations. RESULTS: The findings revealed distinct admission and discharge patterns based on facility and regional factors. Notably, intermunicipal units with 5 and more municipalities collaborating had higher relative risk ratios (RRR) for discharging to hospital (RRR = 1.50, 95%CI: 1.30-1.72) compared with independent MIPAC units. Large MIPAC units with more than 5 beds had increased relative risk ratios of patients admitted from the hospital than from home (RRR = 4.29, 95%CI: 1.56-11.78). Additionally, regional disparities existed, with units in the Central (RRR = 2.29, 95%CI: 1.56-3.38) and Western Norway health authorities (RRR:1.58, 95%CI: 1.22-2.06) displaying higher nursing home discharge rates than units in the South-Eastern Norway health authority. CONCLUSIONS AND IMPLICATIONS: This study confirms the Norwegian MIPAC services' adherence to admission avoidance policies and identifies significant variations in service delivery across regions and facilities. The Norwegian MIPAC model also has potential to inspire other countries in developing admission avoidance services in the primary care setting.
