N2 - Disseminated intravascular coagulation (DIC) is a potentially life-threatening condition that causes systemic coagulation to be turned on and coagulation factors to be used up. However, the evidence for DIC in malaria patients is still not clear, and small case series and retrospective studies have shown varying results. This meta-analysis was intended for the evaluation of the evidence of DIC among malaria patients using a meta-analysis approach. The protocol for the systematic review was registered at PROSPERO as CRD42023392194. Studies that investigated DIC in patients with malaria were searched in Ovid, Scopus, Embase, PubMed, and MEDLINE. The pooled proportion with 95% confidence intervals (CI) of DIC among malaria patients was estimated using a random-effects model. A total of 1837 articles were identified, and 38 articles were included in the meta-analysis. The overall proportion of DIC in malaria was 11.6% (95% CI: 8.9%–14.3%, I2: 93.2%, 38 studies). DIC in severe falciparum malaria and fatal malaria was 14.6% (95% CI: 5.0–24.3%, I2: 95.5%, 11 studies) and 82.2% (95% CI: 56.2–100%, I2: 87.3, 4 studies). The estimates of DIC among severe malaria patients who had multi-organ dysfunction with bleeding, cerebral malaria, acute renal failure, and ≥2 complications were 79.6% (95% CI: 67.1–88.2%, one study), 11.9% (95% CI: 7.9–17.6%, one study), 16.7% (95% CI: 10.2–23.3%, ten studies), and 4.8% (95% CI: 1.9–7.7%, nine studies), respectively. The proportion estimates of DIC among the patients with malaria depended on the Plasmodium species, clinical severity, and types of severe complications. The information from this study provided useful information to guide the management of malaria patients. Future studies are needed to investigate the association between Plasmodium infection and DIC and to understand the mechanism of malaria-induced DIC.
