Effect of Hospital Linens on Unit-Acquired Pressure Injuries for Adults in Medical ICUs: A Cluster Randomized Controlled Trial.
Article in Critical care explorations, 2021. 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
Researchers have shown in laboratory studies that different types of fabrics were associated with changes in skin moisture, friction, shear, and temperature that may predispose patients to pressure injury. There was an association between type of fiber used in hospital linens and pressure injury development in previous clinical studies. We examined if bed linens made from a newly developed synthetic fiber fabric affected occurrence rate, time to development, and severity of unit-acquired pressure injury in critically ill adult inpatients.
designCluster randomized controlled trial.
settingFive adult medical ICUs within one quaternary care center in the Midwest United States. PATIENTS: Patients were assigned to a unit based on bed availability. In total, there were 3,332 patients in the study.
interventionsParticipating medical ICUs were randomly assigned to cotton fiber or synthetic fiber linens for the first 6 months of the study period, and assignment reversed after a 14-day washout period for the final 6 months. MEASUREMENTS AND MAIN
resultsUnit-acquired pressure injury occurrence rate, time to first unit-acquired pressure injury, and severity were evaluated using generalized mixed effect models with patient as a random effect, and a marginal Cox proportional hazards model with repeated admissions from the same patient accounted for by use of a sandwich estimator of the variance. There were 1,706 patients on cotton fiber linens and 1,626 patients on synthetic fiber linens. Groups were similar on demographics except race and admitting diagnosis groupings. Occurrence rate (
conclusionsLinen type did not affect unit-acquired pressure injury occurrence rate, severity, or timing. Standard unit-acquired pressure injury prevention efforts may be more cost-effective than investment in synthetic fiber linens.
