A comparison of hospital and community stay in patients who underwent compulsory admission before and after the 2007 Amendment to the Mental Health Act in Taiwan

Objective: The main purpose of this study was to assess the empirical findings of compulsory admission for psychiatric disorders before and after the 2007 amendment to the Mental Health Act in Taiwan.

Methods: A matched case-control study design was applied. Participants were selected using the National Health Insurance Research Database (NHIRD) in Taiwan. The control and case data were collected in 2006 and 2011, and the number of compulsory admission cases was recorded with a case-control ratio of 1:4, along with information on age (±3 years) and gender. In 2006, the number of patients recruited was 9265, including 1853 compulsorily admitted patients and 7412 voluntarily admitted patients. In 2011, the number of patients recruited was 4505, including 901 compulsorily admitted patients and 3604 voluntarily admitted patients.

Results: The data collected for the patients who underwent compulsory admission before and after the amended Mental Health Act included gender, diagnosis, Charlson Comorbidity Index Score (CCIS), length of stay in an acute hospital ward (days), hospital accreditation level, ownership, teaching hospital status, psychiatrist gender and age, and hospital location. Although the number of compulsory admission cases (1853 vs. 901) markedly decreased and the length of stay in an acute hospital ward (30.7 ± 25.0 days vs. 39.0 ± 22.6 days) increased from 2006 to 2011, the readmission rate was reduced from 52.6% in 2006 to 42.5% in 2011.

Conclusions: The average lengths of hospital stay and community survival time were greater for compulsorily admitted patients than those for voluntarily admitted patients. This result might be attributed to a number of changes implemented since the 2007 amendment of the Mental Health Act, including a strict review process for compulsory admissions and a new discharge planning process, which require further research for approval.
