Prescribing patterns in older people with advanced chronic kidney disease towards the end of life.
Article in Clinical kidney journal, 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
Background: Advancing age and chronic kidney disease (CKD) are risk factors for polypharmacy. Polypharmacy is associated with negative healthcare outcomes. Deprescribing, the systematic rationalization of potentially inappropriate medications, is a proposed way of addressing polypharmacy. The aim of this study was to describe longitudinal prescribing patterns of oral medications in a cohort of older people with advanced CKD in their last years of life. Methods: The European QUALity (EQUAL) study is a European, prospective cohort study of people ≥65 years with an incident estimated glomerular filtration rate (eGFR) of ≤20 mL/min/1.73 m Results: Data from 563 participants were analysed (comprising 2793 study visits) with a median follow-up time of 2.2 years (interquartile range 1.1-3.8) pre-death. Participants' numbers of prescribed oral medications increased steadily over the years approaching death-7.3 (95% confidence interval 6.9-7.7) 5 years pre-death and 8.7 (95% confidence interval 8.4-9.0) at death. Over the years pre-death, the proportion of people prescribed (i) proton-pump inhibitors and opiates increased and (ii) statins, calcium-channel blockers and renin-angiotensin-aldosterone system inhibitors decreased, whilst (iii) beta-blockers, diuretics and gabapentinoids remained stable. At their final visits pre-death 14.6% and 5.1% were prescribed opiates and gabapentinoids, respectively. Conclusion: Elderly people with advanced CKD experienced persistent and increasing levels of polypharmacy as they approached the end of life. There was evidence of cessation of certain classes of medications, but at a population level this was outweighed by new prescriptions. This work highlights the potential for improved medication review in this setting to reduce the risks associated with polypharmacy. Future work should focus at the individual patient-clinician level to better understand the decision-making process underlying the observed prescribing patterns.
