Background and objective Sepsis and septic shock are major healthcare issues in surgical patients admitted to the surgery ward or ICU, affecting millions of people worldwide annually, with a mortality rate between one in three and one in six of those affected. The incidence and mortality of sepsis vary greatly by region, with the highest prevalence in Sub-Saharan Africa, Oceania, South Asia, East Asia, and Southeast Asia. Of all sepsis cases in 2017, 33.1 million people suffered from ill health due to underlying infectious diseases, and 15.8 million suffered from underlying injuries or non-communicable diseases.  Methods This prospective observational study was conducted at the Jimma University Medical Centre (JUMC) in Jimma town in southwest Ethiopia, from April 2023 to October 2023. All surgical patients aged ≥15 years who presented with or developed septic shock at the Jimma University Medical Centre were included. Results The study involved a total of 61 patients. The median age of the patients was 45 years [interquartile range (IQR): 40-60 years], and 77% (n=47) of the patients were male. The most frequent source of infection in this study was community-acquired infection (83.3%, n=49). The most common focus of sepsis was the intra-abdominal infection of the digestive system (82%, n=50). Lactate level testing and blood cultures before administering antibiotics were not done for all septic shock patients. Source control surgery was performed in 52.5% (n=32) of patients after developing septic shock, and 84.4% (n=27) of surgeries were performed within 24 hours. The 30-day mortality rate was 80.3%, with an ICU mortality rate of 78.94%. The median length of stay in the ICU was three days (IQR: 1-5 days), and the median length of hospital stay was six days (IQR: 2-15 days). Conclusions The mortality rate in our cohort was higher compared to that in studies from high-income and low-income countries. There was poor adherence and compliance with the Surviving Sepsis Campaign (SSC) (the one-hour bundle) guidelines. The length of stay in hospitals and ICUs was lower compared to studies from high-income countries due to the high early mortality rates.
