Drug prescription before and after dialysis initiation in older patients: a nationwide study.
Article in BMC geriatrics, 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
backgroundOlder patients on dialysis have a complex regimen of drugs to manage their chronic kidney disease (CKD), associated complications, and co-morbidities. Our aim was to describe drug use in the year before and after dialysis initiation in the older population.
methodsWe included all patients aged ≥ 65 years initiating chronic dialysis in France between 2010 and 2019 identified from the national kidney replacement therapy registry and matched with the national health data system. Drug use prevalence was described by pharmacotherapeutic classes, based on anatomical therapeutic chemical codes, and estimated quarterly for patients with ≥ 1 drug dispensing in the year before and after the initiation of dialysis. Analysis was stratified according to dialysis modality, sex, and age at dialysis initiation.
resultsAmong 55,238 patients included, hyper-polypharmacy (≥ 10 drugs) rose to 76% at dialysis initiation, and slightly decreasing afterwards. Non-CKD-related drugs, including insulins, psychotropic, analgesic and non-antihypertensive cardiovascular drugs, showed stable prevalence, except for proton pump inhibitors (PPI) use which rose sharply before dialysis (40.8% to 54.8%) and then stabilized. Conversely, CKD-related drugs varied. At dialysis initiation, antihypertensives (except diuretics), potassium binders, and hypouricemic agents use declined, while calcium supplementation rose then stabilized. Vitamin D and phosphate binder use increased steadily. Trends in drug use patterns were similar across dialysis modality, sex and age.
conclusionPrescription changes occur at dialysis initiation, particularly for CKD-related drugs. Hyperpolypharmacy was highly prevalent, yet much of it is likely appropriate given the complex clinical profile of older dialysis patients. Further work is needed to explain the high prevalence of PPI.
