van.boven@umcg.nlPurpose: Smart medication adherence monitoring devices can provide objective and granular drug utilization data and help patients engaging with their treatment.
In this proof-of-concept study, the acceptability and technical robustness of a novel smart pill bottle prototype (SPBP) were assessed in order to allow further optimization.Methods: The SPBP is an app-controlled automatic dispense system, capturing real-time data on a web-based platform, which sends text reminders and measures storage conditions.A heterogeneous group of ten volunteers was asked to dispense placebo capsules with the SPBP and to follow a predefined dosing schedule for a trial period of 2 weeks.
Afterwards, a questionnaire was filled out during a short interview.Primary outcome was dispense adherence as measured alarecre.com by the bottle.Other study outcomes included system acceptability (System Usability Scale [SUS]), self-reported adherence (MARS) and technical robustness of the bottle’s mechanics (electronic pill dispenser) and sensors (bottle temperature).
Results: The overall dispense adherence rate as measured by the SPBP was 88%.All participants completed the study and four participants had an adherence rate of 100% during the study.The dispense adherence rates corresponded well with participants’ self-reported adherence with an average MARS total score of 23.
6 (out of 25).Participants judged the system easy to use, with a mean SUS score of 79.3 (range: 57.
5– 97.5).The overall mean temperature difference between the bottle sensor and calibrated external sensor was − 0.
82°C (range: − 1.37°C to − 0.21°C).
Conclusion: The SPBP was well accepted and this study provides data for further optimization and follow-up studies.Smart adherence technologies such as these may change the way healthcare professionals, trialists and patients manage medication adherence.Keywords: smart device, real-time monitoring, medication management, electronic data, medication dispenser, mobile app.
