1 · What the graph read from it

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.

2 · The registry

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

backgroundNurse staffing in psychiatric inpatient care is difficult to plan because reliable measures of patient demand are lacking. Existing indicators are not well established across diverse patient groups. The Health of the Nation Outcome Scales (HoNOS), routinely collected in Switzerland, may provide a pragmatic proxy for patient acuity to inform staffing decisions. DESIGN AND

methodsWe conducted a multicentre cross-sectional study (Match

resultsData from 107 psychiatric inpatient units in 13 hospitals (25,294 patient cases) showed wide variation in unit structures and patient mental health status but relatively little variation in staffing patterns. The median number of beds was 21, and the typical early shift included 2 registered nurses. Regression analyses indicated that higher HoNOS total scores and several single items were significantly associated with increased RN staffing, with the total score showing the strongest effect. A 20% increase in the HoNOS total score corresponded to 48.5 additional registered nurse hours per week or 1.3 full-time equivalents per year. Comparing predicted with reported staffing, smaller units tended to fall below and larger units above their predicted levels.

conclusionsRoutinely collected clinical data, particularly HoNOS scores, were linked to nurse staffing in psychiatric inpatient care. Patient acuity and unit size were both associated with staffing, indicating that routine data can provide a pragmatic basis for more transparent and sustainable workforce planning.
