Intensive care patients eligible for intermediate care unit-level care: a single-centre prospective cohort study in Belgium.
Article in Critical care science, 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
objectiveTo estimate the number of intensive care unit hospitalization days that could have been managed at an intermediate care unit level and to assess the impact of intermediate care unit-eligible patients on intensive care unit-free days, hospital-free days, and nursing workload.
methodsThis single-center, prospective cohort study included all patients admitted to the intensive care unit of an academic hospital between June 1, 2021, and May 31, 2022. All adult (> 18 years of age) patients with an intensive care unit stay exceeding 24 hours were eligible for inclusion. Data from a total of 1,547 patients were analysed. Daily, intensive care unit head nurses identified patients eligible for intermediate care unit management based on predefined criteria. Nursing workload was quantified using the Nursing Activities Score, and 16,478 Nursing Activities Score assessments, recorded at the end of each nursing shift, were collected.
resultsA total of 1,457 intensive care unit hospitalization days (16.7% of the total) were classified as eligible for intermediate care unit-level management. An increase in cumulative intermediate care unit days was significantly associated with fewer intensive care unit - and hospital-free days (adjusted incidence rate ratio = 0.98 [95%CI 0.97 - 0.99] for both). A strong negative correlation was observed between the monthly proportion of intermediate care unit-eligible intensive care unit days and the intensive care unit occupancy rate (R = -0.703, p = 0.011). By shift, the median Nursing Activities Score for intensive care unit patients was 72.4 [59.6 - 87.5] compared to 63.5 [52.6 - 72.8] for intermediate care unit-eligible patients in the morning, 71.5 [58.1 - 86.6] versus 56 [47.8 - 66.1] in the afternoon and 66.1 [53.5 - 81.1] versus 53.9 [45 - 64.7] during night shifts (p < 0.001 for all).
conclusionThis study highlights the potential impact of early identification of intermediate care unit-eligible patients on optimizing the use of intensive care unit beds and improving the organization of patient care. A lower Nursing Activities Score might help select patients for intermediate care unit care, supporting the clinical relevance of such a score in the daily assessment of intensive care unit patients.
