Providers’ perspectives on adherence to hormonal therapy in breast cancer survivors. Is there a role for the digital health feedback system?
- 14 Downloads
Despite the benefits of hormonal therapy (HT) adherence remains suboptimal in ER positive breast cancer patients. Medication adherence is challenging to assess and tends to be overestimated. The Digital Health Feedback System (DHFS) consists of an ingestible sensor attached to a pill that sends intake date and time to a smart phone or computer. Patients can share this information with health care providers and other persons. The DHFS can also send reminders. This mixed methods study examined providers’ perceptions of HT medication adherence. The potential role of the DHFS in enhancing medication tracking and adherence was also explored. We conducted semi-structured interviews with key informants (N = 10). Questions examined perceptions about adherence barriers and facilitators, challenges tracking adherence, and views on the DHFS. Findings informed the development of a survey that was administered online (N = 19). Providers emphasized the importance of fostering open and trustful communication around adherence. The most mentioned challenges to assessing adherence were the patient not disclosing discontinuation immediately (78.9%) and over-reporting adherence (57.9%). The perceived potential benefits of DHFS were the ability to track adherence better (94.7%) and reminders to take the medication (68.4%). Safety to ingest a sensor was a major perceived barrier (8 4.2%). Interventions that target providers and doctor-patient communication are warranted to enhance adherence and reduce communication delays around HT discontinuation. DHFS has the potential to enhance HT adherence by directly targeting barriers. Future studies should also examine the feasibility of adopting the DHFS with cancer patients.
