Hypothesis
Can a new toolkit effectively measure the impact of different electronic patient record (EPR) system features on clinical consultations?
Conclusion
The ALFA method allows for precise observation of clinical consultations and can demonstrate differences between EPR systems.
Supporting Evidence
- The ALFA toolkit allows for the aggregation and navigation of multiple observations.
- Statistical comparisons showed significant differences in coding times between EPR systems.
- Four channels of video were found to be optimal for observing consultations.
- The outputs from the ALFA toolkit can be used to create UML models for software development.
- Patients generally accepted the multichannel video recording method.
Takeaway
The ALFA toolkit helps doctors see how different computer systems affect their consultations, making it easier to choose the best one.
Methodology
The study involved filming live consultations with 22 general practitioners using different EPR systems and analyzing the data collected through various methods.
Potential Biases
The study may be biased due to the small sample size and the specific settings of the pilot.
Limitations
The pilot data only included one clinician per system, limiting the ability to generalize findings.
Participant Demographics
General practitioners from four different practices were involved in the study.
