Prevalence of Delirium and Its Related Factors in Burn Patients; a Systematic Review andMeta-Analysis

Considering the importance of deliriumdisorder in burn patients and its complications, the present systematic review andmeta-analysis aimed to determine the prevalence of deliriumand its related factors in burn patients.

A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, and Web of Science, as well as Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted fromMedical Subject Headings such as "Prevalence", "Delirium", and "Burns" from the earliest to the 17th of July, 2023.

In total, 2,710 burn patients participated in ten original studies. Among the participants, 64.6% were male. In the ten studies, the reported pooled prevalence of delirium among burn patients was 20.5% (95% CI: 10.9% to 35.0%; I2=96.889%; P<0.001). Also, factors such as total body surface area, duration of hospitalization, mortality, days on ventilator, alcoholism, benzodiazepine dose, methadone dose, age, male gender, ICU days, operation days, wound care under anesthesia, and opioid dose had a significant correlation with the prevalence of delirium in burn patients.

Health managers and policymakers can reduce the prevalence of delirium in burn patients by eliminating or reducing factors associated with it.
