The eDosette study – Optimizing medication use and safety in community dwelling seniors

The information from this study allows clinicians to optimize and individualize patients’ prescribed medications, improving safety and effectiveness.

Research Results

Findings: The eDosette was successfully implemented in all participants’ homes. The image data captured by the eDosette was successfully used to generate participant-specific Medication Administration Records (MARs). By analyzing these MARs, specific medication administration times, medication use patterns and participant medication adherence rates could be reported. Participant adherence rates ranged from a low of 64% to a maximum of 100%. No relevant side-effect alerts were generated by any participant during the entire study. Overall, participant feedback was positive for acceptability and usability.

About the Project

As our population ages, the burden of chronic medical conditions increases and patients self-manage increasingly complex medication regimes. It is common for medications not to be taken as prescribed. This can be due to medication complexity, side effects or discordance between doctor and patient about treatment goals.

Dosette boxes simplify taking pills, however they do not provide any data and how and which pills a patient may be taking. This study was a trial of an eDosette box (electronic Dosette box) which transmits data on a MAR to doctors and pharmacists about which medications the patient is actually taking, as well as a side effect alert button.
