[Compliance, concordance, adherence]

Area of Science:

• Pharmacology
• Health Informatics
• Patient Adherence Research

Background:

• Ambulatory pharmacotherapy often involves deviations from prescribed drug dosages, primarily underdosing.
• Accurate medication dosing histories are crucial for understanding patient adherence.
• Electronic monitoring offers a more precise method for tracking medication events compared to traditional methods.

Purpose of the Study:

• To highlight the evolution and impact of electronic monitoring in tracking medication adherence.
• To demonstrate how electronic data replaces anecdotal evidence in understanding prescription discrepancies.
• To showcase the benefits of electronic monitoring in improving patient care and medication management.

Main Methods:

• Utilizing electronic time-stamping of medication events, starting with eyedrop dispensers in 1977.
• Implementing electronically monitored packages for oral dosage forms since 1988.
• Leveraging automatic, inviolable data collection with high sampling rates (60/hr).

Main Results:

• Electronic monitoring reveals frequent and significant deviations in ambulatory pharmacotherapy, mostly downward dosing.
• Data show previously unrecognized patterns, including time-of-day and day-of-week effects on medication adherence.
• The 'white coat effect' in medication management has been identified through electronic monitoring.

Conclusions:

• Electronic monitoring provides objective, high-resolution data on medication-taking behavior.
• This technology facilitates a better understanding of discrepancies between prescribed and actual drug dosing.
• Improved medication management strategies can be developed based on electronic monitoring insights, enhancing patient care.
