Abstract
BACKGROUND: The involuntary admission regulated under the Mental Health Act has become an increasingly important issue in the developed countries in recent years. Most studies about the distribution and associated factors of involuntary admission were carried out in the western countries; however, the results may vary in different areas with different legal and socio-cultural backgrounds. AIMS: The aim of this study was to investigate the proportion and associated factors of involuntary admission in a psychiatric emergency service in Taiwan. METHODS: The study cohort included patients admitted from a psychiatric emergency service over a two-year period. Demographic, psychiatric emergency service utilization, and clinical variables were compared between those who were voluntarily and involuntarily admitted to explore the associated factors of involuntary admission. RESULTS: Among 2,777 admitted patients, 110 (4.0%) were involuntarily admitted. Police referrals and presenting problems as violence assessed by psychiatric nurses were found to be associated with involuntary admission. These patients were more likely to be involuntarily admitted during the night shift and stayed longer in the psychiatric emergency service. CONCLUSIONS: The proportion of involuntary admissions in Taiwan was in the lower range when compared to Western countries. Dangerous conditions evaluated by the psychiatric nurses and police rather than diagnosis made by the psychiatrists were related factors of involuntary admission. As it spent more time to admit involuntary patients, it was suggested that multidisciplinary professionals should be included in and educated for during the process of involuntary admission.
