Complications Associated With Mortality in the National Surgical Quality Improvement Program Database

Area of Science:

• Surgical outcomes research
• Patient safety and quality improvement
• Health services research

Background:

• Postoperative mortality is often multifactorial, making cause attribution difficult.
• Understanding key complications is vital for targeted clinical interventions.
• This study aimed to identify postoperative complications most independently associated with 30-day mortality.

Purpose of the Study:

• To determine which postoperative complications have the strongest independent association with 30-day mortality.
• To inform clinical focus on the most impactful complications affecting patient survival.

Main Methods:

• Analysis of 2012-2013 National Surgical Quality Improvement Program data.
• Multivariable least absolute shrinkage and selection operator regression to adjust for risk factors.
• Population attributable fraction method used to calculate attributable mortality.

Main Results:

• Over 1.19 million patients analyzed; 0.77% experienced 30-day mortality.
• Bleeding, respiratory failure, and septic shock were the leading causes of attributable mortality.
• Complications like UTI and pneumonia impacted mortality differently across age groups.

Conclusions:

• Focusing resources on high-impact complications like respiratory failure and infections is recommended.
• Special attention is needed for complications affecting younger patients due to their longer life expectancy.
