Barriers to adherence to endotracheal tube suctioning guidelines among intensive care nurses at a Tanzanian national hospital: A qualitative study.
Article in PloS one, 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
backgroundEndotracheal tube suctioning (ETS) is a critical procedure for mechanically ventilated patients. Evidence-based guidelines exist to ensure its safe performance; however, adherence remains suboptimal, especially in resource-limited settings. This study aimed to explore the barriers to ETS guideline adherence among ICU nurses at Muhimbili National Hospital (MNH), Tanzania.
methodsAn exploratory qualitative study was conducted in the medical and surgical ICUs of MNH. Seventeen ICU nurses with ≥1 year of experience were purposively sampled. Semi-structured interviews were performed, audio-recorded, transcribed verbatim, and analyzed using inductive thematic analysis following Braun and Clarke's framework.
resultsThree key barriers emerged: (1) Resource scarcity, including critical shortages of staff, equipment, and supplies; (2) Human and behavioral challenges, such as knowledge deficits and resistance to change away from routine practice; and (3) Guideline accessibility and usability, concerning poor accessibility and a perception that guidelines were not tailored to the local context.
conclusionNon-adherence to ETS guidelines primarily reflects systemic constraints rather than individual neglect. Strengthening adherence requires multi-level interventions: improving staffing and resources, providing continuous training, and adapting international guidelines to the local context.
