Systematic screening using FRAX® leads to increased use of, and adherence to, anti-osteoporosis medications: an analysis of the UK SCOOP trial.

Summary: In the large community-based SCOOP trial, systematic fracture risk screening using FRAX^® led to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care. Introduction: In the SCreening of Older wOmen for Prevention of fracture (SCOOP) trial, we investigated the effect of the screening intervention on subsequent long-term self-reported adherence to anti-osteoporosis medications (AOM). Methods: SCOOP was a primary care–based UK multicentre trial of screening for fracture risk. A total of 12,483 women (70–85 years) were randomised to either usual NHS care, or assessment using the FRAX^® tool ± dual-energy X-ray absorptiometry (DXA), with medication recommended for those found to be at high risk of hip fracture. Self-reported AOM use was obtained by postal questionnaires at 6, 12, 24, 36, 48 and 60 months. Analysis was limited to those who initiated AOM during follow-up. Logistic regression was used to explore baseline determinants of adherence (good ≥ 80%; poor < 80%). Results: The mean (SD) age of participants was 75.6 (4.2) years, with 6233 randomised to screening and 6250 to the control group. Of those participants identified at high fracture risk in the screening group, 38.2% of those on treatment at 6 months were still treated at 60 months, whereas the corresponding figure for the control group was 21.6%. Older age was associated with poorer adherence (OR per year increase in age 0.96 [95% CI 0.93, 0.99], p = 0.01), whereas history of parental hip fracture was associated with greater rate adherence (OR 1.67 [95% CI 1.23, 2.26], p < 0.01). Conclusions: Systematic fracture risk screening using FRAX^® leads to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care. [ABSTRACT FROM AUTHOR]
