Predictors of ICU mortality in septic patients in a resource-limited African setting: a prospective multicenter cohort study in Lubumbashi, DRC.
Article in Journal of anesthesia, analgesia and critical care, 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
backgroundSepsis remains a leading cause of intensive care unit (ICU) mortality globally, with the highest burden observed in low- and middle-income countries where diagnostic capacity, timely referral, and access to organ support are limited. However, commonly used prognostic tools rely on laboratory and monitoring resources that are often unavailable in such settings. This study aimed to identify independent predictors of ICU mortality among adults with sepsis in Lubumbashi, Democratic Republic of the Congo, and to develop a context-adapted prognostic score suitable for resource-constrained environments.
methodsWe conducted a prospective multicentre cohort study across three ICUs between January 2021 and April 2023. Adults meeting Sepsis-3 criteria were consecutively enrolled. Clinical status, basic laboratory parameters, therapeutic timing, and socioeconomic characteristics were recorded within 24 h of ICU admission. Independent predictors of 28-day mortality were identified using multivariable logistic regression. A simplified point-based prognostic model (SPARS-Basique) was constructed and evaluated for discrimination (AUROC) and calibration, with internal validation using bootstrap resampling (1,000 iterations). The outcome of interest was 28-day ICU mortality.
resultsSeven variables were independently associated with ICU mortality: delayed ICU admission > 5 days, low socioeconomic status, absence of health insurance, GCS ≤ 10, SpO
conclusionsSepsis mortality in Lubumbashi ICUs remains high and is influenced by both biological severity and structural barriers to timely care. The SPARS-Basique score demonstrated good internal performance for early risk stratification of ICU mortality in this cohort. However, as this was an exploratory derivation study in a modest sample, external validation in larger, independent cohorts is required before broader clinical application can be considered.
