The eDosette Study: Optimizing medication use and safety in community dwelling seniors

This study is a trial of the eDosette, an electronic device that provides information about how and when a patient takes their medications, and any side effects experienced, to their family doctor and pharmacist.

Possible Research Results

Anticipated findingsWe anticipate that the eDosette will demonstrate that older adults do not always take medications as prescribed. The timely communication of these findings to the primary care team will result in a reduction in medication complexity and improved medication adherence.

Impact of findingsThe eDosette will be able to provide previously unavailable information about how an older adult takes their medications to their primary care team. In addition, older adults will be given the opportunity to more easily report medication side effects as they occur. This eDosette has the potential to make an ongoing economic impact through its potential to reduce waste from improperly taken medications, and by reducing hospital and emergency visits from adverse drug events. If this project does result in older adults taking their medication correctly, there is potential to relieve that part of caregiver burden which will hopefully improve the caregiver’s quality of life and the older adults’ health. The eDosette device was created to empower older adults to manage their medications appropriately and provide an automatic way for them to let their primary care team know when they’re in danger of experiencing a possible side effect.

About the Project

As our population ages, the number of chronic medical conditions and medications given to the elderly increases. It is, therefore, not surprising to find that frail elderly patients have trouble keeping track of and taking their medications as told by their doctor. Blister packs and dosettes can simplify taking pills, however they do not provide any information about how and which pills a patient may be taking.

This study is looking to see whether the eDosette can help the frail elderly take their medications better. More importantly, the study will determine whether the information sent by the eDosette will allow family doctors and pharmacists to match patients' medications to their ability to safely self-administer them, while keeping in mind what is best for each patient. This study will be able to show how frail elderly patients are taking their medications, how the eDosette can prompt improved medication regimes, and lastly, further refine the eDosette device for a larger future study.
