"We learn while doing": informal training experiences of critical care nurses managing dialysis technologies in intensive care units.
Article in BMC nursing, 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
backgroundAcute kidney injury (AKI) is among the most prevalent life-threatening complications in intensive care units (ICUs), with continuous renal replacement therapy (CRRT) being the primary mode of renal support for haemodynamically unstable patients. Despite the technical complexity of CRRT, formal training programmes for ICU nurses remain inconsistent across healthcare settings. This study explored the informal training experiences of critical care nurses managing dialysis-dependent patients in Al-Ahsa, Saudi Arabia.
methodsA qualitative descriptive design was employed, guided by reflexive thematic analysis as described by Braun and Clarke. Semi-structured in-depth interviews were conducted with 20 purposively sampled ICU nurses with direct CRRT management responsibilities across healthcare facilities affiliated with King Faisal University, Al-Ahsa. Data were analysed through six iterative phases of thematic analysis. Ethical approval was obtained from the Institutional Review Board of King Faisal University.
resultsFour overarching themes were generated: (1) "Figuring It Out on the Floor", nurses described learning CRRT management primarily through observation and immediate bedside practice; (2) "The Colleague Is the Textbook", experienced peers served as informal educators, transmitting practical knowledge through demonstration and narration; (3) "Anxiety Behind the Machine", nurses articulated persistent fear of error that gradually transformed into competence through repeated exposure; and (4) "Gaps the System Does Not See", participants identified a systemic absence of structured CRRT training and called for formalised competency frameworks.
conclusionsCritical care nurses in this setting rely heavily on informal, peer-mediated learning to acquire CRRT competencies in the absence of standardised institutional training. These findings highlight an urgent need for structured simulation-based CRRT education, written protocols, and competency assessment frameworks. Nursing leaders and ICU educators must recognise and address the informal learning burden carried by frontline nurses to safeguard patient safety and support workforce development. CLINICAL
