Empowering Family Glaucoma Risk Communication Using QR-Code-Mediated Online Intervention.

PURPOSE:Attempts at engaging relatives of glaucoma patients in education and screening have had limited success. This study explores the feasibility of an electronic intervention to facilitate direct yet reliable glaucoma risk communication between open-angle glaucoma patients (probands) and their first-degree relatives (FDRs). DESIGN:Prospective survey and assessment of intervention. PARTICIPANTS:Fifty adult probands, engaging 140 FDRs. METHODS:Phase I was an iterative process involving creating a customized website and Quick Response (QR)-code-based intervention designed with input from probands, FDRs of patients, community members, and researchers. In phase II, the intervention was deployed in a clinical setting; this involved recruiting probands who had a smartphone and were willing to use the QR-code to message their FDRs a standard message, including a website link about glaucoma risk in FDRs and the importance of getting examined. Follow-up interviews were conducted with probands 1 to 2 weeks after their clinic visit to assess the impact of the intervention. Demographic data, website analytics, and participant feedback were collected and analyzed. MAIN OUTCOME MEASURES:Increased awareness of glaucoma risk among FDRs and enhanced discussions. RESULTS:At the time of the first interview, probands reported that 70% of the FDRs were aware of the probands' glaucoma diagnosis, but only 26% had undergone glaucoma screening. Ninety percent of probands had no issues using the QR-codes. Website analytics recorded 73 visits from 51 distinct internet protocol addresses (IPs). After receiving the standard message, 95% of FDRs followed up with the probands, actively discussing glaucoma. Of the probands, 84% completed the follow-up interview 1 to 2 weeks after enrollment. Fifty-nine percent of the FDRs were reported to have scheduled screening appointments. The collected feedback revealed that 96% of probands found the intervention helpful, fostering glaucoma discussions with their FDRs and improving probands' comfort level in discussing health issues with FDRs from baseline (very comfortable: 88%, comfortable: 8%, neutral: 2%, and very uncomfortable: 2%) to the follow-up interview (very comfortable: 98% and comfortable: 2%). CONCLUSIONS:This innovative online method of communicating the risk of glaucoma to FDRs of probands prompted and increased the comfort level of familial discussions of glaucoma. More than half of FDRs reported making an appointment to get screened for glaucoma.
