PURPOSE: Fever is frequently encountered in ICU. It is unclear if targeted temperature control is beneficial in critically ill patients with suspected or confirmed infection. We conducted a systemic review and meta-analysis to answer this question.

METHODS: We systematically reviewed major databases before January 2020 to identify randomized controlled trials (RCTs) that compared antipyretic with placebo for temperature control in non-neurocritical ill adult patients with suspected or confirmed infection. Outcomes of interest were 28-day mortality, temperature level, hospital mortality, length of stay, shock reversal, and patient comfort.

RESULT: 13 RCTs enrolling 1963 patients were included. No difference in 28-day mortality between antipyretic compared with placebo (risk ratio [RR] 1.03; 95% CI 0.79-1.35). Lower temperature levels were achieved in the antipyretic group (MD [mean difference] -0.41; 95% CI -0.66 to -0.16). Antipyretic use did not affect the risk of hospital mortality (RR 0.97; 95% CI 0.73-1.30), ICU length of stay (MD -0.07; 95% CI -0.70 to 0.56), or shock reversal (RR 1.11; 95% CI 0.76-1.62).

CONCLUSION: Antipyretic therapy effectively reduces temperature in non-neurocritical ill patients but does not reduce mortality or impact other outcomes.
