The aim of the study was to evaluate the association of death within 8 days after discharge to home from the emergency department with a non-causative diagnosis in a prospective cohort study. METHODS: The records from the emergency department were filed by personal identification number and included information on gender, age, admission, discharge and diagnosis. The cause of death was obtained from a nation-wide registry by record linkage. Mortality per 100,000 within 8 days and the hazard ratio and 95% confidence intervals (CIs) were calculated for all causes of death in a time-dependent analysis. RESULTS: A non-causative diagnosis had been given to 11% of those who died within 8 days after discharge home. The mortality per 100,000 within 8 days was 208.5, within 15 days 347.4 and within 30 days 648.6. In the analysis of deaths within 8 days, the hazard ratio was higher for men than women and increasing age was significantly associated with high mortality. The hazard ratio for non-causative diagnosis was 0.44 (95% CI 0.20-0.96) as compared to causative diagnosis, adjusted for gender and age. CONCLUSION: The mortality rate within 8 days of discharge found in the present study is considerably higher than findings in previous studies. Death shortly after discharge of patients with non-causative diagnosis may indicate a misjudgement of the patients' condition at the time of discharge.
