Assessing Hospital Surgical Quality

Area of Science:

• Healthcare quality improvement
• Surgical outcomes research
• Health services research

Background:

• Hospital performance benchmarking is crucial for quality improvement.
• Credible benchmarking requires standardized surgical procedures and patient risk assessment.
• Variability in patient types and procedures complicates direct comparisons.

Purpose of the Study:

• To develop a novel hospital surgery report card for performance improvement.
• To enable accurate benchmarking of surgical outcomes across institutions.
• To identify specific areas of strength and deficiency in surgical programs.

Main Methods:

• Utilized Medicare data for general, orthopedic, and vascular surgery patients.
• Employed a matching methodology: each hospital patient was matched to 10 typical and 10 well-resourced control patients.
• Matching was based on 200 characteristics, including procedures, comorbidities, socio-demographics, and multimorbidity.
• Hospitals were graded based on outcome differences between matched patient sets.
• Examined 20 high-volume Pennsylvania hospitals, providing detailed report cards for two examples.

Main Results:

• Significant variations in quality and performance grades were observed among hospitals.
• Hospital A demonstrated better outcomes than matched controls, while Hospital B had significantly worse outcomes.
• Analysis of 20 large Pennsylvania hospitals revealed 5 with significantly higher mortality and 2 with significantly lower mortality than controls.

Conclusions:

• Surgical programs gain valuable insights from comparing their outcomes against national benchmarks.
• Understanding performance for specific patient subsets (e.g., with/without multimorbidity) is essential.
• Matching-based detailed reports effectively highlight program-specific deficiencies and strengths for various surgeries and patient types.
