SEVERITY OF PSYCHIATRIC-DISORDER IN DAY HOSPITAL AND INPATIENT ADMISSIONS

This study assessed whether severity of psychiatric disorder varies ac ross day hospital and in-patient units according to local need, and wh ether severity of disorder predicts length of stay and therefore costs . Data were collected for a consecutive series of 2230 in-patients and 712 day patients using the Social Behaviour Scale (data completed by nurses) and diagnosis and Clinical Global Impression (CGI) (completed by doctors). Severity of illness of subjects admitted to in-patient un its, but not to day hospitals, was associated with under-privileged ar ea score (UPA). Length of in-patient stay is most accurately predicted by Clinical Global Impression and six other variables relating to dia gnosis, demographic status and individual hospital. Improved resource allocation for mental health services could be achieved if severity of disorder was routinely collected.
