Sepsis after major cancer surgery

Area of Science:

• Oncology
• Infectious Disease Epidemiology
• Health Services Research

Background:

• Cancer patients undergoing surgery face elevated risks of developing sepsis.
• This study evaluates postoperative sepsis incidence and risk factors after major cancer surgeries (MCS).

Purpose of the Study:

• To determine the incidence of postoperative sepsis following major cancer surgeries.
• To identify patient and hospital characteristics associated with increased sepsis risk.

Main Methods:

• Analysis of 2,502,710 patients undergoing 8 types of MCS from 1999-2009 using the Nationwide Inpatient Sample.
• Logistic regression and generalized estimating equations were used to assess predictors of sepsis and mortality.
• Linear regression analyzed trends in sepsis incidence and mortality.

Main Results:

• MCS-related sepsis incidence increased by 2.0% annually, while mortality remained stable.
• Esophagectomy patients and those with non-private insurance had higher odds of sepsis.
• Lung resection patients and those with perioperative liver failure had higher sepsis-related mortality odds.
• Increased hospital volume correlated with decreased odds of sepsis and associated mortality.

Conclusions:

• Postoperative sepsis incidence following MCS rose between 1999 and 2009, with stable mortality rates.
• Disparities in sepsis risk were linked to patient and hospital factors.
• Hospital volume emerged as a significant, modifiable factor for improving sepsis outcomes in cancer surgery patients.
