  1. Abbreviations: N Number of patients, RR Rate Ratio (Rate Interv /Rate Control), p probability, 95% CI 95% confidence interval
  2. Sub-group analyses: (1) Only controls surviving Lead days: Controls who survived the intervention group’s median lead days in the hospital. Excluded: Controls who died during the first 4-5 days and their matches. (2) Only intervention patients with an index emergency hospital episode. Excluded: Intervention patients with index episode in the municipality or planned hospitalisation and their matches
  3. Final model adjustment variables: Emergency admissions: Fixed effect: Count of emergency admissions last year, Site. Random effect: site, triplet-stratum ID.
  4. Final model adjustment variables: Sum emergency inpatient days: Fixed effect: Quintile of lead days, Sum emergency bed days last year, Site. Random effect: site, triplet-stratum ID
  5. Final model adjustment variables: Count 30-day Readmissions: Fixed effect: Quintile of lead days, Count re-admissions last year, Site. Random effect: site, triplet-stratum ID.
