Prevalence and associated factors of inappropriate analgesic drug use among community-dwelling older adults with chronic musculoskeletal pain: a cross-sectional study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMusculoskeletal disorders are frequently associated with pain in older adults, and the use of inappropriate analgesics drugs is common. Understanding the patterns and factors of inappropriate analgesic use may help reduce its prevalence among older adults with chronic musculoskeletal pain.
methodsThis cross-sectional study evaluated 215 older adults aged ≥ 60 years who experienced chronic musculoskeletal pain and used oral medication to relieve pain within the previous 3 months. Participants were recruited through home visits using the community health register in Ban Phru, Hat Yai District, Songkhla Province (Southern Thailand) between July and December 2023. Analgesic use was determined by directly inspecting the drugs that participants were taking within the previous 3 months, regardless of whether they were prescribed or self-purchased. The name, dose, and source of each medication were recorded and cross-checked with the 2023 American Geriatrics Society Beers Criteria to identify potentially inappropriate drugs. This approach enabled differentiation into three patterns of inappropriate analgesic drug use: potentially inappropriate medication use, overtreatment, and undertreatment. Factors associated with the inappropriate use of analgesic drugs were analysed using multivariate logistic regression analysis.
resultsInappropriate analgesic drug use was prevalent in 66.5%. Regarding the prevalence rates by pattern, potentially inappropriate, overtreatment, and undertreatment were prevalent in 71.3%, 24.5%, and 33.6%, respectively. Non-prescribed polypharmaceutical packs (adjusted odds ratio [aOR] [95% confidence interval {CI}] = 11.45 [3.32, 72.15], P < 0.001) and pain interfering with enjoyment of life (aOR [95% CI] = 1.16 [1.04, 1.30], P = 0.007) were significantly associated with inappropriate analgesic drug use.
conclusionsInappropriate analgesic use was common, affecting 66.5% of community-dwelling older adults with chronic musculoskeletal pain. Non-prescribed polypharmaceutical packs and pain interference were significant predictors of inappropriate use. These findings underscore the influence of inappropriate self-medication, suggesting the need for greater attention from healthcare providers to promote safe and rational analgesic use in this population.
