Prescribing patterns and medication costs in patients on maintenance haemodialysis and peritoneal dialysis.

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
backgroundPolypharmacy is a significant clinical issue for patients on dialysis but has been incompletely studied. We investigated the prevalence and costs of polypharmacy in a population-based cohort of participants treated with haemodialysis (HD) or peritoneal dialysis (PD).
methodsWe studied adults ≥20 years of age in Alberta, Canada receiving maintenance HD or PD as of 31 March 2019. We characterized participants as users of 0-29 drug categories of interest and those ≥65 years of age as users/non-users of potentially inappropriate medications (PIMs). We calculated the number of drug categories, daily pill burden, total annual cost and annual cost per participant and compared this to an age- and sex-matched cohort from the general Alberta population.
resultsAmong 2248 participants (mean age 63 years; 39% female) on HD (n = 1781) or PD (n = 467), the median number of prescribed drug categories was 6 [interquartile range (IQR) 4-8] and the median daily pill burden was 8.0 (IQR 4.6-12.6), with 5% prescribed ≥21.7 pills/day and 16.5% prescribed ≥15 pills/day. Twelve percent were prescribed at least one drug that is contraindicated in kidney failure. The median annual per-participant cost was ${\$}$3831, totalling ≈${\$}$11.6 million annually for all participants. When restricting to the 1063 participants ≥65 years of age, the median number of PIM categories was 2 (IQR 1-2), with a median PIM pill burden of 1.2 pills/day (IQR 0.5-2.4). Compared with PD participants, HD participants had a similar daily pill burden, higher use of PIMs and higher annual per-participant cost. Pill burden and associated costs for participants on dialysis were >3-fold and 10-fold higher, respectively, compared with the matched participants from the general population.
conclusionParticipants on dialysis have markedly higher use of prescription medications and associated costs than the general population. Effective methods to de-prescribe in the dialysis population are needed.
