Effect of a one time guideline based educational video intervention on osteoporosis related knowledge
Abstract
INTRODUCTION: Osteoporosis remains underdiagnosed and undertreated, partly due to insufficient patient knowledge. This study aimed to assess osteoporosis-related knowledge and to evaluate the immediate and short-term effects of a one-time educational intervention through a guideline-based video in an adult online population. MATERIALS AND METHODS: In this prospective, randomized controlled trial, adults aged ≥ 18 years were recruited via an established online panel. Participants were randomized to an intervention group, which viewed a standardized educational video on osteoporosis, or a control group without intervention. Osteoporosis knowledge was assessed using the Facts on Osteoporosis Quiz (FOOQ) and the Osteoporosis Knowledge Assessment Tool (OKAT). Knowledge retention was evaluated in the intervention group after one week. Between-group comparisons were performed using Man-Whitney U tests, χ² tests, and odds ratios. RESULTS: A total of 513 participants were included (intervention group: n = 198; control group: n = 315), with no significant differences in baseline demographic or clinical characteristics. Immediately after the intervention, osteoporosis-related knowledge was significantly higher in the intervention group compared with controls, as measured by both OKAT (11.6 vs. 8.8 points, p < 0.0001) and FOOQ (13.2 vs. 11.1 points, p < 0.0001). The proportion of participants with poor knowledge (FOOQ ≤ 10 points) was lower in the intervention group (20.7% vs. 41.3%; OR…
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: 513 participants or records.
