Clavien-Dindo Analysis of NSQIP Data Objectively Measures Patient-Focused Quality

Area of Science:

• Surgical Quality Improvement
• Patient Safety
• Health Services Research

Background:

• Current quality measures are often administrative burdens, not reflecting provider performance.
• Surgeon-developed measures, such as the NSQIP, align better with clinical practice and outcomes.
• The study investigates the impact of NSQIP participation on surgical outcomes.

Purpose of the Study:

• To test the hypothesis that NSQIP participation improves surgical outcomes.
• To assess the association between NSQIP and measurable improvements in postoperative adverse events.
• To evaluate the effectiveness of combining NSQIP with the Clavien-Dindo system for quality measurement.

Main Methods:

• Comparative analysis of elective general surgical cases from 2014 to 2017.
• Utilized the Clavien-Dindo severity scaling system to grade postoperative adverse events (AEs).
• Calculated patient population burden of AEs by summing grades and dividing by case volume.

Main Results:

• Case volume increased by 67% from 2014 to 2017.
• The ratio of patient burden to case volume improved from 0.92 to 0.73.
• While overall AE incidence was not significantly different, most AEs decreased; sepsis-related respiratory care emerged as a key improvement target.

Conclusions:

• NSQIP participation is associated with improved surgical performance and reduced patient burden.
• Combining NSQIP with Clavien-Dindo provides objective, patient-specific surgical quality measurement.
• Perioperative morbidity impact has decreased, demonstrating the value of this combined approach.
