BACKGROUND: There is limited quantitative evidence to investigate short-term suicide rates although the risk of suicide in psychiatric patients is exceptionally high in the early post-discharge period. This study aimed to explore the trends of the 30 days suicide rate after discharge using population-based data from Korea.
METHODS: This study was conducted on psychiatric patients aged 15 years or older discharged between 2010 and 2018. Patients were extracted from the National Health Insurance Claim Database (NHICD) and information on suicide was obtained from the National Statistical Office. Age-standardized suicide rate (ASR) and Standardized Mortality Ratio (SMR) within 30 days after discharge was estimated and tested using joinpoint regression.
RESULTS: Of the 1,576,028 patients discharged from hospitals from 2010 to 2018, 53.9 % were male and 47.9 % were aged between 40 and 59 years. The 30 days ASRs for psychiatric patients after discharge varied from 174.9 to 218.0 per 100,000 patients with no clear trend excluding patients with schizophrenia and anxiety disorder. The SMR for suicide within 30 days after discharge was 66.8 in 2016-2018, and patients aged 20 to 39, female, and patients with depression had high SMRs compared to other groups. LIMITATIONS: Factors that may impact the suicide were not considered in this study. Since the NHICD data is collected for payment of medical expenses, there may be scope for inaccuracies.
CONCLUSIONS: The 30 days suicide rate after psychiatric discharge has failed to decrease between 2010 and 2018. This study recommends early interventions after discharge and intensive interventions for patient groups who may be vulnerable to suicide.
