The evaluation of chronic psychiatric care.

During the past two decades the reduction in the size of the mental hospital population in this country has closely followed statistical predictions for bed requirements both in Canada and in the province of Ontario. The decrease has been most pronounced among chronic non-retarded patients. While these patients are now less evident in hospital statistics, it is suggested that improvements in their state may be more apparent than real, owing to differences in the terminology and numerators employed in presenting mental health statistics. Further, concern has been expressed about the quality of care received by former chronic patients now scattered through the community in a variety of after-care programs. Readmission rates have greatly increased in absolute terms and as a proportion of total admissions. The evaluation of the management of chronic psychiatric patients is discussed.
