Abstract 18980: Improving Anticoagulation Knowledge and Quality of Life in Older Adults Using Tablet Mobile Applications
Background: Older adults with cardiovascular diseases who require oral anticoagulation therapy (AT) report difficulty managing medications and diet, which affects therapeutic benefit and quality of life (QOL). Mobile health (mHealth) tools such as health applications (app) via smartphones or tablets can assist in managing AT but such tools have not been tested among older adults including Spanish speaking elders.
Objective: The objective of the study was to test the feasibility of an mHealth intervention composed of culturally appropriate and age-sensitive components to improve QOL in older adults on AT.
Methods: The pilot study used a single-arm, experimental, pre-post design to assess the feasibility of a 12-week mHealth-based intervention in older adults with AT by examining changes in outcomes (ie, knowledge, adherence, QOL, perception, depression) and usability of the warfarin app on a 10-inch tablet computer after 3-month use.
Results: Twenty older patients from two anticoagulation clinics have enrolled in the study - average age 67.7 ± 9.8 years; predominantly male (14/20, 70%); Caucasians (9/20, 45%), Hispanics (8/20, 40%); high school completion (13/20, 65%); living with family (16/20, 80%); average number of comorbidity 3.4 (±1.4). Fifteen participants completed 3-month follow-ups; two dropped due to inability to use the app; one died; two are currently on use of the app. Outcomes were improved from baseline to 3 months (see Table). The mean satisfaction with and mean usefulness of the app were 5.4 of 7 (±1.5) and 5.4 of 7 (±1.4) in usability survey after 3 months.
Conclusions: Our findings suggest that on-going mHealth intervention for older adults with chronic diseases show promise in being able to enhance anticoagulation knowledge and QOL with the treatment. The satisfaction of mHealth intervention using the health app was moderate to high in this sample. The findings can be used to modify the health app to make the mHealth intervention more elder-friendly.
