Feasibility and effectiveness of a digital voice assistant for improving anti-osteoporosis medication adherence, and osteoporosis knowledge and attitudes, in postmenopausal women with osteoporosis: A 12-month randomised controlled trial
Abstract
Digital voice assistants (DVAs) are feasible for delivering a digital health intervention designed to improve osteoporosis self-management in postmenopausal women with osteoporosis. However, the DVA intervention did not improve anti-osteoporosis drug adherence, nor did it enhance osteoporosis knowledge or attitudes in this population.
Purpose: To determine feasibility and effectiveness of a digital voice assistant (DVA) intervention for improving anti-osteoporosis medication adherence, and osteoporosis knowledge and attitudes, in postmenopausal women with osteoporosis.
Methods: This 12-month single-blinded, randomised controlled trial included 50 postmenopausal women with osteoporosis randomised to DVA (N = 25) or control (N = 25) for 6 months, followed by a 6-month follow-up period. DVA participants received an Amazon Alexa device that delivered osteoporosis education videos, medication reminders and interactive quizzes. Control participants received emails with links to osteoporosis information. Anti-osteoporosis medication possession ratio (MPR; acceptable adherence defined as ≥ 0.8) was determined using Pharmaceutical Benefits Schedule data. Osteoporosis knowledge was measured using the Osteoporosis Knowledge Assessment Tool (OKAT) and medication attitudes were measured using the Adherence Evaluation of Osteoporosis Treatment (ADEOS-12) questionnaire.
Results: The mean ± SD age of participants was 64.3 ± 6.1 years and 6-month DVA intervention adherence (number of DVA…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 50 participants or records.
