Effectiveness of VoxQR (Voice QR Code) In Enhancing Knowledge Medication Adherence for Geriatric Hypertensive Patients in Koronadal City

Abstract

This study examined the effectiveness of VoxQR (Voice-powered QR codes) in enhancing knowledge and medication adherence among geriatric hypertensive patients in Koronadal City, where nonadherence to antihypertensive medication is a common issue due to cognitive decline and difficulty understanding treatment regimens. A quasi-experimental design was employed, and patients aged 60 and above were selected using purposive sampling. Data were gathered using a validated questionnaire that measured adherence and knowledge before and after the intervention. Results showed notable improvements, including a shift in medication adherence from moderate-low to moderate high levels, increased understanding of medication purpose, dosage, and timing. These findings indicate that VoxQR significantly enhanced medication adherence and knowledge, suggesting that voice-based QR technology is a practical and accessible tool for supporting chronic disease management in older adults.
