Composite Measures for Profiling Hospitals on Surgical Morbidity

Q: What is the clinical evidence from this study?

Study design: Observational. Population: Surgical morbidity. Intervention: Composite measure of surgical morbidity vs. Standard ACS-NSQIP approach (simple rates of risk-adjusted morbidity). Primary outcome: Hospital morbidity in the subsequent year (discrimination of future performance) (OR 2.65, 95% CI 1.83-3.85).

Key result

A composite measure better discriminated future hospital morbidity for ventral hernia repair than the standard approach (bottom vs top 20% OR 2.65, 95% CI 1.83-3.85 vs OR 1.30, 95% CI 0.87-1.96).

Why the study?

Does a novel composite measure improve the reliability of hospital morbidity rankings compared to the standard risk-adjusted morbidity approach in patients undergoing surgical procedures?

Key Points

To determine whether a novel composite measure combining multiple quality indicators improves the reliability and predictive validity of hospital surgical morbidity rankings compared to standard risk-adjusted morbidity.
Analyzed ACS-NSQIP data (2008–2009) for patients undergoing colectomy, ventral hernia repair, abdominal aortic aneurysm (AAA) repair, and lower extremity bypass surgery.
Developed a composite measure integrating morbidity, reoperation, length of stay, and morbidity from related procedures, weighted using empirical Bayes reliability adjustments.
Assessed predictive performance by evaluating how effectively composite and standard measures from 2008 predicted hospital morbidity rates in 2009.
Composite measures explained a higher proportion of hospital-level variation in morbidity than standard measures across all four procedures: ventral hernia repair (58% vs 8%), colon resection (33% vs 14%), AAA repair (51% vs 38%), and lower extremity bypass (32% vs 3%).
For ventral hernia repair, hospitals in the lowest-performing quintile based on the composite measure had nearly threefold higher morbidity the following year compared to the top quintile (OR: 2.65; 95% CI: 1.83–3.85), whereas the standard approach showed a non-significant difference (OR: 1.30; 95% CI: 0.87–1.96).

Does a novel composite measure improve the reliability of hospital morbidity rankings compared to the standard risk-adjusted morbidity approach in patients undergoing surgical procedures?

Population

Patients in the ACS-NSQIP database undergoing colectomy, ventral hernia repair, abdominal aortic aneurysm repair, or lower extremity bypass surgery between 2008 and 2009.

Exposure

Novel composite measure combining quality indicators from morbidity, reoperation, length of stay, and morbidity with other potentially related procedures, empirically weighted and adjusted for reliability.

Comparator

Standard ACS-NSQIP approach for assessing hospital rates of risk-adjusted morbidity.

Outcome

Proportion of hospital-level variation in morbidity explained and ability of 2008 measures to predict morbidity in 2009.

Main Result

Odds Ratio: 2.65 (95% CI 1.83–3.85)

A novel composite measure better reflects hospital quality and discriminates future performance than simple rates of risk-adjusted morbidity across multiple surgical procedures.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Composite morbidity measures may boost ranking reliability; leaves open whether they guide better surgical quality or outcomes.

Dimick et al. (2012) conducted an observational in Surgical morbidity. Composite measure of surgical morbidity vs. Standard ACS-NSQIP approach (simple rates of risk-adjusted morbidity) was evaluated on Hospital morbidity in the subsequent year (discrimination of future performance) (OR 2.65, 95% CI 1.83-3.85). A composite measure better discriminated future hospital morbidity for ventral hernia repair than the standard approach (bottom vs top 20% OR 2.65, 95% CI 1.83-3.85 vs OR 1.30, 95% CI 0.87-1.96).
