Think aloud protocols offer a novel method for data collection in community pharmacies, revealing previously unrecognized e-prescribing weaknesses and enhancing vigilance. Challenges included pharmacy interruptions and participant recall during think aloud sessions.
Area of Science:
- Pharmacy Practice
- Health Informatics
- Human-Computer Interaction
Background:
- Think aloud protocol is an underutilized data collection method in community pharmacy settings.
- E-prescribing technology implementation presents unique challenges in pharmacy practice.
Purpose of the Study:
- To describe the application of think aloud protocols in community pharmacies.
- To identify issues arising from e-prescribing technology use.
- To report on the benefits and challenges of using think aloud protocols for examining e-prescribing systems.
Main Methods:
- Employed think aloud protocol combined with direct observation.
- Recruited 16 pharmacists and pharmacy technicians from seven community pharmacies.
- Participants verbalized thoughts while processing electronic prescriptions.
Main Results:
- Identified previously unrecognized weaknesses in e-prescribing systems.
- Increased participant awareness and vigilance in processing electronic prescriptions.
- Observed challenges included pharmacy interruptions and difficulty maintaining verbalization.
Conclusions:
- Think aloud protocol provides a novel method for understanding technology use issues in community pharmacy.
- This method yields objective data on e-prescribing, beyond user opinion.
- Identified real-time challenges and potential patient safety issues, informing system redesign.
