title: Reinventing the community hospital: a retrospective population-based cohort study of a natural experiment using register data.
abstract: To investigate whether implementation of municipal acute bed units (MAUs) resulting from the Norwegian Coordination Reform (2012) was associated with reductions in hospital admissions, particularly for the elderly.
  
  
  
  A municipality-based retrospective comparative cohort study using monthly population-based registry data analysed with fixed-effects log-log regressions.
  
  
  
  Norwegian municipalities and hospitals.
  
  
  
  All patients admitted to secondary hospital care in Norway between 2010 and 2014, excluding psychiatric admissions, with additional focus on admission type and elderly age subgroups.
  
  
  
  Monthly admission rates in total and by age group for all patients, patients admitted with acute conditions and with acute conditions at internal medicine departments.
  
  
  
  The introduction of MAUs was associated with a small yet significant overall negative effect on hospital admissions. The reduction in all admissions was significant for the entire population (-1.2%, 95% CI -2.0% to -0.0%) and slightly stronger for those aged 80 years and above (-1.9%, 95% CI -3.0% to -1.0%). The more detailed analysis of the elderly population aged 80 years and above revealed that effects were affected by the institutional characteristics of the MAUs. The significant effects ranged between -1.6% and -8.6%, depending on the availability of physicians on duty at the MAUs, the MAUs location or combinations thereof.
  
  
  
  Introduction of MAUs following implementation of the Norwegian Coordination Reform in 2012 was associated with a significant reduction in hospital admissions primarily for the elderly. Our findings suggest that this type of intermediate care is a viable option in an effort to alleviate the burden on hospitals by reducing the acute secondary care admission volume. Further examinations focused on cost-effectiveness, health status of patients, number of patients treated at the MAUs and comparing other intermediate care alternatives would all add important perspectives to the issue.
