A service evaluation of outcomes in two in-patient recovery units

Community-care unit model of residential mental health rehabilitation services in Queensland, Australia: predicting outcomes of consumers 1-year post discharge

AIMS

Community care units (CCUs) are a model of residential psychiatric rehabilitation aiming to improve the independence and community functioning of people with severe and persistent mental illness. This study examined factors predicting improvement in outcomes among CCU consumers.

METHODS

Hierarchical regression using data from a retrospective cohort (N = 501) of all consumers admitted to five CCUs in Queensland, Australia between 2005 and 2014. The primary outcome was changed in mental health and social functioning (Health of the Nation Outcome Scale). Secondary outcomes were disability (Life Skills Profile-16), service use, accommodation instability, and involuntary treatment. Potential predictors covered service, consumer, and treatment characteristics. Group-level and individualised change were assessed between the year pre-admission and post-discharge. Where relevant and available, the reliable and clinically significant (RCS) change was assessed by comparison with a normative sample.

RESULTS

Group-level analyses showed statistically significant improvements in mental health and social functioning, and reductions in psychiatry-related bed-days, emergency department (ED) presentations and involuntary treatment. There were no significant changes in disability or accommodation instability. A total of 54.7% of consumers demonstrated reliable improvement in mental health and social functioning, and 43.0% showed RCS improvement. The majority (60.6%) showed a reliable improvement in psychiatry-related bed-use; a minority demonstrated reliable improvement in ED presentations (12.5%). Significant predictors of improvement included variables related to the CCU care (e.g. episode duration), consumer characteristics (e.g. primary diagnosis) and treatment variables (e.g. psychiatry-related bed-days pre-admission). Higher baseline impairment in mental health and social functioning (β = 1.12) and longer episodes of CCU care (β = 1.03) increased the likelihood of RCS improvement in mental health and social functioning.

CONCLUSIONS

CCU care was followed by reliable improvements in relevant outcomes for many consumers. Consumers with poorer mental health and social functioning, and a longer episode of CCU care were more likely to make RCS improvements in mental health and social functioning.

Longitudinal analysis of statistical and clinically significant psychosocial change following mental health rehabilitation

Purpose: With appropriate mental health rehabilitation, schizophrenia is increasingly associated with reports of recovery and stability. However, there is little empirical evidence evaluating the efficacy of services delivering this care. This study evaluated the effectiveness of rehabilitation for improving psychosocial function in consumers with schizophrenia.Methods: An electronic database of standardized assessment instruments mandated and maintained by the health service was retrospectively reviewed to extract ratings of psychosocial function, daily living skills, and mood state from consecutive admissions to an inpatient rehabilitation service. Outcomes were compared at admission, discharge, and one-year follow-up to identify statistically significant change. Individual reliable and clinically significant change was also assessed by comparison with a normative group of clients functioning independently in the community.Results: From admission to discharge the rehabilitation group made statistically significant gains in psychosocial function and daily living skills. Improvements were reliable and clinically significant in one-quarter to one-third of individual consumers. Approximately half sustained their improvements at follow-up, although this represented only a small fraction of the overall cohort. Consumers not demonstrating gains exhibited psychometric floor effects at admission.Conclusions: Rehabilitation can produce statistically and clinically significant immediate improvement in psychosocial function for a sub-set of consumers with elevated scores at admission. The durability of any gains is less clear, and strategies promoting longer-term maintenance are encouraged. Furthermore, currently mandated outcome measures are confounded by issues of sensitivity and reporting compliance, and exploration of alternative instruments for assessing recovery is recommended.Implications for RehabilitationRoutinely collected standardized outcome measures can be used to investigate the effectiveness of mental health rehabilitationIn addition to statistical significance, the clinical significance of outcomes should be evaluated to identify change that is individually meaningfulCurrently mandated outcomes instruments do not adequately evaluate many individuals' recovery journeyMental health service evaluation and quality improvement processes would likely benefit from adoption of recovery-oriented measures.
