title: Effectiveness of psychiatric inpatient care.
abstract: There is a growing demand for evaluating the process and outcome of mental health care. Most healthcare providers routinely collect and register data related to the process of treatment, and it is important to acquire more knowledge about how to make use of these databases. The aim of this study was to investigate the outcome of psychiatric inpatient care in relation to different clinical factors, using the Global Assessment of Functioning Scale (GAF) as a measure of outcome. Another objective was to explore the ability of routinely collected and registered data to provide valuable information about patients and their care. The studied psychiatric inpatient sample consisted of 816 care episodes with GAF ratings made both at admission and at discharge for 648 patients. Variables used in the study included GAF score at admission and at discharge, age, gender, diagnosis, length of stay and ward affiliation. The overall mean GAF change was 20.74, and the overall effect size Cohen's d 1.67, which corresponds to a large effect. The mean GAF change for women was 21.6, with an effect size of 1.80, and for men 19.4 with an effect size of 1.52. The effect size spectra including all groups of diagnoses ranged from 1.03 (substance-related disorders) to 2.33 (other mood disorders). Length of stay and ward affiliation also showed significant results concerning GAF change. Some limitations in this study could depend on the absence of randomization procedures and a control group. Another limitation concerns the insufficient control of the inpatient care interventions performed. The results support the capacity of the GAF to function as a measure of outcome in relation to different clinical factors, such as length of stay and diagnosis. Support was also found for the importance and usefulness of routinely collected and registered data.
