Introduction: Sepsis is global health priority and the leading cause of death in critical care. The SEPSIS 3 criteria introduced in 2016 is the latest tool in diagnosing sepsis. It uses SOFA and qSOFA scores in place of the SIRS criteria for better ability to predict mortality in patients with suspected infections. The performance of these scores in critical care units outside high-income countries remains largely unknown.

Methods: We compared the performance of SOFA and qSOFA in predicting the in-hospital mortality of an adult critical care unit in Kenya. We conducted a retrospective review of all patients admitted to the critical care units with suspected infection between 1 January 2017 and 31 December 2017. A standardized electronic data collection tool was be used to collect demographic, clinical and outcome data on the participants. Area under the receiver operating characteristic curves (AUROC) with 95% confidence intervals was used to compare SOFA and qSOFA.

Results: We enrolled 450 patients with a mean age of 56 years [SD ± 19.10] and 57.60% were male. Majority of the patients, 352 (78.20%), presented through the emergency department. Pneumonia was the commonest source of infection 293 (65.10%). There were 92 deaths (mortality rate of 20.44%). The majority of patients, 371 (82.44%) manifested a SOFA score of ≥ 2 and 190 (42.22%) had a qSOFA score of ≥ 2. SOFA score was superior in predicting in hospital mortality compared to qSOFA with an AUROC = 0.799 [0.752-0.846] vs. 0.694 [0.691-0.748, P < 0.001].

Conclusion: A SOFA score of two or more is better than qSOFA score in predicting in-hospital mortality among adult critical care patients with suspected infection. This finding suggests that SOFA is an appropriate tool in the initial diagnosis sepsis in critical care setting in a developing country.
