Improving return rates for health-care outcome

Area of Science:

• Health Services Research
• Clinical Research Methodology
• Psychiatric Patient Monitoring

Background:

• Follow-up studies are crucial for quality assurance in psychiatric care.
• Patient attrition can significantly impact the validity of follow-up data.
• Existing methods for improving follow-up rates require optimization.

Purpose of the Study:

• To evaluate the effectiveness of abbreviating the SF-36 Health Status Survey in reducing patient attrition.
• To assess the impact of a token monetary incentive on follow-up data return rates.
• To compare the efficacy of questionnaire abbreviation and monetary incentives in minimizing data loss.

Main Methods:

• Adult psychiatric patients (n=146) were randomly assigned to different study arms.
• One group received a shortened SF-36 questionnaire.
• Another group received the standard SF-36 plus a treatment assessment form, with or without a monetary incentive.

Main Results:

• Both questionnaire abbreviation and monetary incentives independently reduced patient attrition by 10%.
• A diminishing returns effect was observed for both interventions.
• No specific interaction effects were detailed, but further study was recommended.

Conclusions:

• Shortening questionnaires and providing small monetary incentives are effective strategies to reduce data loss in psychiatric follow-up.
• The effectiveness of these methods may plateau, indicating a need for careful consideration of implementation.
• Further investigation into the synergistic or interactive effects of questionnaire length and incentives is recommended for optimizing follow-up protocols.
