Hypothesis
How do chronic pain patients' treatment preferences change after participating in N-of-1 trials?
Conclusion
Many patients undergoing N-of-1 trials for chronic pain changed their treatment preferences, but not always in line with the trial results.
Supporting Evidence
- 40% of participants changed their treatment preferences after the trial.
- Patients often retained their initial preferences despite trial results.
- Treatment superiority varied significantly based on how it was defined.
Takeaway
When people with chronic pain try out personalized treatment trials, about 40 out of 100 of them might change their minds about what treatment they want, but sometimes they stick with their original choice even if the trial suggests a different option.
Methodology
This observational study analyzed chronic pain patients' treatment preferences before and after N-of-1 trials, focusing on changes in preferences and the influence of trial results.
Potential Biases
Potential biases may arise from patients' prior experiences and expectations influencing their treatment preferences.
Limitations
The study design is observational and may not definitively establish causality between N-of-1 trial participation and changes in treatment preferences.
Participant Demographics
The mean age of participants was 55 years, with 45% female and 30% non-white.
