Abstract
Objective: The objective of this study was to investigate the readmission rate, and the level of patient disturbance and community care associated with readmission following Community Treatment Orders (CTOs) in New South Wales, Australia.
Method: The readmission rates of all patients given CTOs within a 4-year period and a matched comparison group were investigated. The following factors were compared before, during and following a CTO: medication non-compliance, number of clinical services and duration of disturbed behaviour preceding hospitalisations.
Results: Of 123 patients on CTOs (mean length, 288 days; SD, 210 days), 38 were readmitted during the CTO, the majority in the first 3 months and a further 21 patients were readmitted following termination of the CTO. Evidence of lower severity of illness in the comparison patients prevented meaningful evaluation of the readmission rates of the two groups. While on CTOs, patients receiving depot medications showed high compliance and a significantly reduced readmission rate compared with that of patients receiving oral medications. In the 2 months prior to hospitalisations during CTOs, compared with those before or after CTOs, patients received more frequent consultations and showed a shorter duration of medication non-compliance and disturbed behaviour. The level of services in the 3 months following discharge were comparable for patients on CTOs and the comparison group.
Conclusions: CTOs may reduce rehospitalisations by use of depot medication. Earlier and possibly more frequent readmissions in the CTO group shortened the disturbance associated with illness recurrence. It would appear that to establish a control group with equivalent severity of disorder necessary to evaluate the impact of CTOs requires a random allocation design.
