Quality-of-life measurement in surgical randomized controlled trials
1Department of Surgery, University of British Columbia, Vancouver, Canada.
Summary
Measuring quality of life in surgical trials is crucial for treatment decisions. Using validated instruments ensures reliable data for future clinical research and patient care.
Area of Science:
- Clinical Trials
- Health Outcomes Research
- Surgical Research
Background:
- Quality-of-life (QoL) measurement is increasingly vital in clinical trials.
- Its application in surgical trials is growing, highlighting its importance in treatment selection and clinical decision-making.
- Validated instruments are essential for reliable QoL data.
Purpose of the Study:
- To review the role and feasibility of quality-of-life measurement in surgical clinical trials.
- To emphasize the importance of using validated instruments over ad hoc measures.
- To encourage the integration of QoL assessment in future surgical trial designs.
Main Methods:
- Review of quality-of-life measurement methodologies in clinical trials.
- Distinction between generic and specific QoL instruments.
- Emphasis on the validation phases of QoL instruments (reproducibility, responsiveness, validity).
Main Results:
- Quality-of-life measurement is feasible and clinically significant in surgical trials.
- Validated generic and specific instruments provide reliable data.
- Ad hoc instruments lack rigorous methodology and yield interpretable results.
Conclusions:
- Quality-of-life assessment is a critical component of surgical clinical trials.
- Well-validated instruments should be prioritized for robust QoL data.
- Investigators should incorporate validated QoL measures in future surgical trial designs.
