"A Matter of Life and Death": Mitigating the Gray Digital Divide in Using Health Information Technologies in the...

A pervasive issue in healthcare is that elderly populations have fallen far behind in using healthcare technologies, a phenomenon known as the gray digital divide. Even more concerningly, the COVID-19 pandemic has dramatically catalyzed health digitization with the potential for lasting demographic-wide impacts. Against this backdrop and drawing on both the digital divide literature and the unified theory of acceptance and use of technology (UTAUT2), we investigated elderly populations' usage of healthcare technologies through analyzing HINTS 6 (2022) survey data. Results show a widespread first- and second-level digital divide in using health information technologies (HITs) between people aged 65 and up and people aged 18-64, including Internet access, health-related Internet use, health-related social media use, health app use, use of wearable electronic health devices, telehealth visits, and accessing online medical records. Moreover, this study finds that education consistently positively predicts Internet use and use of various HITs by the elderly; income is the next reliable predictor but not as consistent as education. Health-related variables are less consistent in predicting the elderly's use of HITs. Theoretical and practical implications of these results are discussed to inform the mitigation of the gray digital divide in healthcare.
