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

backgroundCritical illness represents a major global health-care burden and critical care is an essential component of hospital care. There are few data describing the prevalence, treatment, and outcomes of critically ill patients in African hospitals.

methodsThis was an international, prospective, point prevalence study in acute hospitals across Africa. Investigators examined all inpatients aged 18 years or older, regardless of location, to assess the coprimary outcomes of critical illness and 7-day mortality. Patients were classified as critically ill if at least one vital sign was severely deranged. Data were collected for the available resources at each hospital and care provided to patients.

findingsWe included 19 872 patients from 180 hospitals in 22 African countries or territories between September, 2023 and December, 2023. The median age was 40 (IQR 29-59) years, and 11 078/19 862 (55·8%) patients were women. There were 967/19 780 (4·9%) deaths. On census day, 2461/19 743 (12·5%) patients were critically ill, with 1688/2459 (68·6%) cared for in general wards. Among the critically ill, 507/2450 (20·7%) patients died in hospital. Mortality for non-critically ill patients was 458/17 205 (2·7%). Critical illness on census day was independently associated with subsequent in-hospital mortality (adjusted odds ratio 7·72 [6·65-8·95]). Of the critically ill patients with respiratory failure, 557/1151 (48·4%) were receiving oxygen; of the patients with circulatory failure, 521/965 (54·0%) were receiving intravenous fluids or vasopressors; and of patients with low conscious level, 387/784 (49·4%) were receiving an airway intervention or placed in the recovery position.

interpretationOne in eight patients in hospitals in Africa are critically ill, of whom one in five dies within 7 days. Most critically ill patients are cared for in general wards, and most do not receive the essential emergency and critical care treatments they require. Our findings suggest a high burden of critical illness in Africa and that improving the care of critically ill patients would have the potential to save many lives.
