Hypothesis
What are the reasons for the poor accrual of patients in a consent-based clinical data registry?
Conclusion
There is significant variation in patient approach and consent rates across sites, influenced by different hospital policies and practices.
Supporting Evidence
- 70% of stroke patients were approached for consent.
- Consent rates varied widely across sites, from 41% to 86%.
- 17% of those approached refused to participate.
Takeaway
This study looked at how many stroke patients were asked to join a research study and how many said yes, finding big differences between hospitals.
Methodology
The study analyzed the percentage of eligible patients approached for participation and the consent rates across different sites.
Potential Biases
There may be selection biases due to differences in how hospitals approached potential participants.
Limitations
The study faced challenges in obtaining a representative sample due to variations in hospital policies and patient approach rates.
