Characterisation and management of therapy-interrupting system errors associated with the use of the HomeChoice cycler for automated peritoneal dialysis.
Article in BMC health services research, 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
backgroundMethodological and technical education of nurses is required to address challenges of technology integration in peritoneal dialysis (PD). We analysed the nature of therapy interrupting system errors in automated peritoneal dialysis (APD) cyclers of a German PD reference care centre and provide applicable resolution proposals.
methodsWe documented therapy interrupting system errors of HomeChoice Pro and HomeChoice Claria cyclers (Baxter, BX, Unterschleißheim, Germany) including the years 2015-2023. We systematically characterise and suggest resolution strategies to these errors based on routinely collected health data and user experience to safely guide nephrology professionals and patients during troubleshooting. The 'reporting of studies conducted using observational routinely collected health data' (RECORD)-statement was considered.
resultsWe identified 49 different therapy interrupting system errors which were assigned to eight major categories: Errors associated to the pressure chamber (N=18), the Digitalboard/EEPROM (N=18, Electrically Erasable Programmable Read Only Memory), air in set (N=3), opening of the set's door (N=3), those associated to the energy system (N=3), the heater system (N=3) and a variety of errors resulting in an abrupt termination or non-commencement of the treatment session without clear group assignment (undefined, N=1) or without sufficient documentation. In total, 138 error incidents were documented during the observational timeframe. In frequential order errors were attributed to the pressure chamber (21.74%,), and air in set (19.57%) where specifically error 2240 occurred in 17.39% of total cases, the Digitalboard/EEPROM (17.39%), the energy or battery (16.67%; No. 1032 in 19/23 cases), the set's door (7.25%) and the heater (4.35%). In 17 cases (12.32%) no error number was documented by the patient or staff. One error cause was registered as undefined (0.72%). Overall, errors were rarely occurring in <0.25% of treatment sessions performed in the observational timeframe.
conclusionThese findings may be useful to guide training purposes for nephrology personnel and persons doing APD. For the manufacturer, the information provided may be helpful to improve error management and information transmission to the persons doing APD with the HomeChoice devices.
