Does Physicians' Clinical Competence, Communication Ability, or Cultural Background Influence Potentially Inappropriate Prescribing of Benzodiazepines and Z-Drugs Among Older Adults With Insomnia?
Article in Pharmacoepidemiology and drug safety, 2024. 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
objectiveThe objective of this study is to estimate the association between physician's age, sex, clinical and communication competencies, and cultural background on benzodiazepines and Z-drugs (BDZ) prescribing to older adults with insomnia.
methodsA cohort of international medical graduates (IMGs) who completed their pre-residency licensure exam in 1998-2004 were linked to all U.S. Medicare patients they provided care to in 2014-2015. Their care records in Parts A, B, and D from all physicians were extracted. The first outpatient visit for insomnia to a study IMG was identified for each patient in that period. The outcome was incident BDZ prescribing by the study physician following the visit. Main exposures were physician age, sex, citizenship at birth, and clinical and communication competency as measured on the licensure exam. The association between physician characteristics and BDZ prescribing, adjusting for physician and patient covariates, was estimated using generalized estimating equations multivariable logistic regression.
resultsWe analyzed 28 018 patients seen by 4069 unique physicians. IMGs born in all other regions of the world were less likely to prescribe BDZs compared to U.S.-born IMGs, with physicians from the United Kingdom being least likely (OR 0.54 [95%CI 0.34-0.85]). Neither physician's clinical competency nor communication ability were associated with BDZ prescribing (OR per 10% increase, respectively: 0.95 [95%CI 0.88-1.02] and 0.98 [95%CI 0.93-1.04]). Older physicians remain more likely to prescribe BDZ (OR per 5-year increase 1.04 [95%CI 1.00-1.08]).
conclusionsThe associations between cultural background and physician's age on BDZ prescribing highlight the potential targets for remedial solutions to reduce the use of potentially inappropriate medications.
