Summary
Tablet PC and digital pen (d-pen) offer efficient data entry for mammography clinical trials, matching traditional methods in speed and user satisfaction. The d-pen shows superior accuracy and speed in handwriting recognition review.
Area of Science:
- Radiology
- Medical Informatics
- Clinical Trials Data Management
Background:
- Efficient data collection is crucial for mammography clinical trials.
- Evaluating new technologies for data entry can improve trial processes.
Purpose of the Study:
- To assess speed, accuracy, ease of use, and user satisfaction of electronic data entry platforms.
- To compare these platforms against traditional paper data entry in mammography trials.
Main Methods:
- Four platforms tested: personal digital assistant (PDA), Tablet PC, digitizer Tablet/PDA Hybrid (DTP Hybrid), and digital pen (d-pen).
- Five radiologists entered data for 20 mammograms using three methods each.
- Data entry times, help requests, handwriting recognition accuracy, and user satisfaction were recorded.
Main Results:
- Tablet PC and d-pen demonstrated comparable speed to paper entry.
- d-pen verification time was significantly lower than secondary electronic entry of paper forms (p<0.001).
- Users reported high satisfaction with Tablet PC, d-pen, and paper methods.
Conclusions:
- Tablet PC and d-pen are effective, user-friendly data entry solutions for mammography trials.
- d-pen offers faster and more accurate handwriting recognition review than manual keyboard entry.
