Hypothesis
Does double-blind control of the data manager affect data entry reliability?
Conclusion
Double-blind control of the data manager should be considered an avoidable cost, and electronic control is more effective for monitoring data-entry reliability.
Supporting Evidence
- Double-blind control did not improve data entry reliability.
- Entries near the end of the insertion sheet had more mistakes.
- Electronic monitoring was more effective than manual checks.
Takeaway
The study found that having a double-blind control for data entry doesn't help reduce mistakes, and using electronic checks is better than manual ones.
Methodology
A cross-sectional survey using data from 6446 medical charts with a single data manager for data entry and double-blind control.
Potential Biases
Using a single data manager may reduce inter-data manager bias but could introduce systematic errors.
Limitations
The study was based on a single data manager, making it difficult to generalize the conclusions.
Participant Demographics
3462 females and 2984 males from a Greek survey.
