Is the short form 36 (SF-36) suitable for routine health outcomes assessment in health care for older people? Evidence from preliminary work in community based health services in England.

STUDY OBJECTIVE

To examine the short form 36 (SF-36) health status measure when used to assess older people's views of the outcome of community based health care.

DESIGN

Completion of a structured questionnaire, before and after intervention alongside in-depth interviews with a subsample of the interviewees.

SETTING

Community based continence and mental health services in two health authorities in the North West Health Region.

PATIENTS

Forty seven older people newly referred to mental health services or continence services between December 1992 and April 1993 participated.

MAIN RESULTS

The SF-36 showed minimal change over time for both patient groups. The more detailed in-depth interviews showed that people experienced positive changes and derived value from contact with services in a number of important ways. For many reasons these benefits were not reflected in their SF-36 scores.

CONCLUSIONS

The SF-36 is not likely to be the "measure of choice" for this type of evaluation, particularly where it involves older patient groups who have high levels of comorbidity. The content of the SF-36 and its lack of detail for individual assessment of change means it masks rather than illuminates patients' views of outcome.
