Evaluation of days alive out of hospital as an outcome after intensive care admission: a national retrospective cohort study.

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
backgroundDays alive out of hospital (DAOH) is defined as the number of days a patient spends alive and out of hospital in a predefined period. Current understanding of the performance of this outcome measure in the intensive care (ICU) population is limited thus we aimed to investigate the relationship between DAOH and prognostic indicators in patients admitted to ICU and to compare the performance of DAOH at 30-days (DAOH30), 90-days (DAOH90) and 180-days (DAOH180).
methodsIn a retrospective cohort study, all patients aged over 18 years admitted to ICU in New Zealand between 1st January 2017 and 31st December 2023 were eligible for inclusion. DAOH was calculated using merged data from the Australian and New Zealand Intensive Care Society (ANZICS) Adult Patient Database (APD) and the National Minimum Dataset (NMDS) data.
results72,546 admissions recorded in the ANZICS APD were linked to NMDS. Median (interquartile range [IQR]) DAOH30 was 15 days (0–22), median (IQR) DAOH90 was 72 days (40–81) and median (IQR) DAOH180 was 160 days (117–171). DAOH90 was negatively correlated with age (ρ= -0.19, p < 0.001) and Acute Physiology and Chronic Health Evaluation (APACHE) II score (ρ = -0.42 p < 0.001). DAOH90 was lower in patients receiving invasive ventilation, vasoactive support and renal replacement therapy and those admitted with severe traumatic brain injury (TBI). Lower median DAOH90 was associated with increased variation in outcome across multiple subgroups. A floor effect was observed for DAOH30 (with a median DAOH30 value of zero days) in patients with high APACHE II score, severe TBI and patients undergoing renal replacement therapy or tracheostomy insertion. The time for the excess hazard of hospitalisation and mortality to reach baseline were 37.3 and 18.6 days respectively but were prolonged in certain patient subgroups.
conclusionsOur study provides evidence to support the use of DAOH for patients admitted to ICU, however DAOH30 is unlikely to be a suitable measure.
