National survey evaluating the introduction of new and alternative staffing models in intensive care (SEISMIC-R) in the UK.
Observational study in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05917574 (A Study to Evaluate the Introduction of New Staffing Models in Intensive Care), which is not on this map. Cited by 1 paper.
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.

Abstract
objectiveTo report on the findings from a national survey of UK intensive care units (ICUs) exploring nurse staffing models currently in use and changes since COVID-19.
designA survey was designed and distributed using a web-based platform to senior unit leads via Intensive care national audit & research centre contacts.
participantsSenior nurses representing the 331 National Health Service adult ICUs across the UK (across 231 hospitals/155 trusts), including the Channel Islands and Isle of Man. OUTCOME MEASURES: A 15-item survey.
resultsA total of 196 survey responses representing 300 units, majority general and single units, resulting in a 90.6% unit-level response rate. ICU unit characteristics included the average number of total, level 3 and level 2 critical care beds of 26.36 (SD=21.48), 15.67 (SD=15.33) and 10.96 (SD=8.86), respectively. Most units reported nurse to patient ratios compliant with national guidelines and service specifications. Post-COVID-19 changes to ICU nurse staffing establishments were reported by 44% respondents, including increases in non-registered staff. However, limited data were provided regarding decision-making around and changes to bedside allocation of nurses since COVID-19.
conclusionsIncreased numbers and use of non-registered staff within the ICU is indicative of an alternative staffing model to address nursing shortages. However, more research is needed to understand how this staffing group is being used compared with, and alongside, registered nurses. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov: NCT05917574.
