Résumé

Introduction : the development of health information and communication technologies (HICTs) could modify thequality and cost of healthcare services delivered to an aging population. However, the acceptance of HICTs—aprerequisite for users to benefit from them—remains a challenge. This population-based study aimed to 1)explore the acceptance of HICTs by community-dwelling older adults as well as the factors associated to theoverall acceptance/refusal of HICTs; 2) identify the factors associated with confidentiality (i.e., access to dataallowed to physicians only versus to all caregivers) in the subgroup of older adults willing to accept HICTs. Methods : A total of 3195 community-dwelling 69–83 year-old members of the Lausanne cohort 65+ were in-cluded. In 2017, participantsfilled out a 9-item questionnaire to assess their acceptance of HICTs (“yes withoutreluctance”;“yes but with reluctance”;“no”). A bivariate analysis was conducted to examine gender and age differences in the acceptance of HICTs. A multivariable logistic regression was performed to model 1) acceptingall or rejecting all HICTs items; 2) willing to share HICTs items with physicians only versus all caregivers.Results:The answer“acceptance without reluctance”ranged from 26.4% to 70.4% across HICTs and was themost frequent answer to six out of nine HICT items. For every HICT item, the acceptance rate decreased acrossage categories in women. Overall, 20.2% accepted all the HICTs without reluctance and 9.9% rejected them all.Older age and a lower level of education were significantly associated with both accepting all HICTs withoutreluctance (OR = 0.78 and OR = 0.65, respectively) and rejecting all HICTs (OR = 1.54 and OR = 2.89, re-spectively). Women and participants with health vulnerability (depressive symptoms, difficulty in activities ofdaily living (ADLs)) were less likely to accept data accessibility to non-physicians. Conclusion : Acceptance of HICTs was relatively high. To deploy HICTs in the older population, demographic, socioeconomic and health profiles, alongside confidentiality concerns, should be considered.
