Systematic review of short-term prognostic factors of HIV patients admitted to an intensive care unit

Abstract

Introduction: Knowing the short-term prognostic factors of critically ill HIV patients admitted to intensive care units (ICUs) in the era of combination antiretroviral therapy (cART) is important for the adoption of preventive measures and more effective treatment. To identify the most significant and common factors that determine short-term mortality, a systematic review of the relevant literature was carried out. Method: An internet search was conducted in three databases indexing scientific articles (PubMed, Scopus, and Web of Science) for studies investigating the prognostic factors of mortality or short-term survival (in ICUs and elsewhere in hospitals following ICU admission) of critically ill HIV-infected patients. The articles were selected according to pre-established criteria and evaluated independently by two researchers. The variables collected were author, year, study location, study type, number of patients with HIV, mortality, significant factors in simple logistic regression and multiple regression, main causes of admission, and inclusion criteria. Results: Twenty-six articles were selected for systematic review. Fifteen dealt with factors that determine mortality in the ICU, nine with hospital mortality following ICU admission, and two with both. Conclusions: Factors associated with the severity of acute disease, such as prognostic scores, albumin, and organ failure (shock and respiratory failure), seem to be more important as determinants of short-term mortality than those associated with HIV.
