Background: Current medication adherence telemonitoring systems have several limitations prompting the need for simpler, low-cost and widely applicable tools. To meet these needs, we propose a novel method consisting in sending a digital feedback of medication intake by just reading a pre-defined Quick Response (QR) code attached on the pills box. Methods: To assess the potential clinical applicability of the proposed QR code-based task, its feasibility was tested among elderly with heart diseases. The primary endpoint was the learning success defined as a correct execution of all QR code-based digital task steps within 10 min. Study outcomes were compared between patients 65-75 years old (younger cohort) and those aged >75 years (older cohort) admitted to the Cardiology ward of a tertiary center. Results: A total of 262 patients were included: 128 (48.9%) were younger and 134 (51.1%) older. Despite a baseline low smartphone use in the overall population (41.2%), patients learning success of the digital task was as high as 75.6%, with lower rates among older vs. younger (67.9% vs. 83.6%, p = 0.005). After adjustment no significant independent association between age and success in learning the QR code-based task was found. Differently, increasing age was a negative independent predictor of smartphone use. The learning time was overall small, but longer in the older group (126 ± 100 vs. 100 ± 60 s, p = 0.03). Conclusions: The QR code-based digital task was highly feasible for elderly with heart diseases suggesting its potential large-scale clinical application and encouraging the investigation of QR code-based systems for medication adherence telemonitoring.

Abstract
Background: Current medication adherence telemonitoring systems have several limitations prompting the need for simpler, low-cost and widely applicable tools. To meet these needs, we propose a novel method consisting in sending a digital feedback of medication intake by just reading a pre-defined Quick Response (QR) code attached on the pills box. Methods: To assess the potential clinical applicability of the proposed QR code-based task, its feasibility was tested among elderly with heart diseases. The primary endpoint was the learning success defined as a correct execution of all QR code-based digital task steps within 10 min. Study outcomes were compared between patients 65-75 years old (younger cohort) and those aged >75 years (older cohort) admitted to the Cardiology ward of a tertiary center. Results: A total of 262 patients were included: 128 (48.9%) were younger and 134 (51.1%) older. Despite a baseline low smartphone use in the overall population (41.2%), patients learning success of the digital task was as high as 75.6%, with lower rates among older vs. younger (67.9% vs. 83.6%, p = 0.005). After adjustment no significant independent association between age and success in learning the QR code-based task was found. Differently, increasing age was a negative independent predictor of smartphone use. The learning time was overall small, but longer in the older group (126 ± 100 vs. 100 ± 60 s, p = 0.03).
