  1. Methods of evaluation of the effects of care Course for Young Psychiatrists Addis Ababa, 28th April 2006 David Goldberg

  2. What are the real aims of your care? • Acute illnesses – include measures of symptom severity • Chronic illnesses – spend less time on symptom severity, use a brief measure, remember Quality of Life • ALWAYS include disability measures • Usually include satisfaction measures

  3. What are the real aims of your care? • Acute illnesses – include measures of symptom severity • Chronic illnesses – spend less time on symptom severity, use a brief measure, remember Quality of Life • ALWAYS include disability measures • Usually include satisfaction measures

  4. Other indicators of care • Unmet Need – measures include the “CAN”, Camberwell Assessment of Need • Economic measures – if you can reduce the cost of care, politicians in your country will be greatly interested!

  5. Evaluation design • Before/after evaluations • Controlled studies • Short/long term outcomes

  6. Design of the Evaluation There are two sorts of control groups: • Random assignment of individuals to the new treatment or the “usual treatment” (called “TAU”) • Choosing two different places with comparable patients, and introducing the new treatment in only one of them Evaluations without a control group are a waste of everyone’s time!

  7. Methods of evaluation of success of training courses Course for Young Psychiatrists Addis Ababa, 28th April 2006 David Goldberg

  8. Evaluation: impact on clinicians • Is it possible to bring about a change in clinician knowledge, attitudes or skills? • Does the intervention improve morale or confidence? • How satisfied are the clinicians with the intervention?

  9. Assessing knowledge • Self-evaluation • Instructor’s opinions • objective measures

  10. Assessing Attitudes • Questionnaires (e.g. Depression Attitude Questionnaire; Attitudes to Psychiatry) • Interviews • structured • semistructured

  11. Skill acquisition • Observed Structured Clinical Examinations • rate against predefined scorecard. Both of these are “before and after”: • Videotaped interviews with real or role-played patients • rated ‘blind’ using structured rating scales • Changes in ability to identify or assess accurately emotional disorder using comparison of patient GHQ rating and PCP rating; numbers of patients identified; prescriptions issued

  12. Improvement in morale/confidence • Self-rated linear analogue scales • Interviews • Post-training assessment rated against pre-training self-assessment of needs/objectives

  13. Evaluation: Impact on process and outcome of care Process of care: • frequency and length of visits • prescription of medication • referrals • use of investigations Outcome of care: • hospitalisations • numbers improved, symptom free

  14. Evaluation: Impact on process and outcome of care • Patient satisfaction • Compliance • Clinical outcome • symptoms • disability • Economic outcome - how many return to work?
