Summary

Quality improvement efforts in surgery show varied trends. While hepatectomy outcomes improved, pancreatectomy surgical site infections increased, highlighting areas needing focused quality improvement initiatives.

Area of Science:

  • Surgical quality improvement
  • Healthcare outcomes research
  • Medical data analysis

Background:

  • Traditional quality improvement often uses hospital-wide benchmarking.
  • Quality improvement can be inconsistent across different surgical procedures.
  • Examining procedure-specific outcomes trends is crucial for targeted improvement.

Purpose of the Study:

  • To identify surgical procedures requiring enhanced quality improvement efforts.
  • To analyze trends in risk-adjusted outcomes for common surgical procedures.
  • To pinpoint specific adverse events and procedures with worsening trends.

Main Methods:

  • Analysis of 1,255,575 operations from 2008-2015 in the American College of Surgeons NSQIP database.
  • Inclusion of ten common procedures: colectomy, esophagectomy, hepatectomy, hysterectomy, pancreatectomy, proctectomy, total hip arthroplasty, total knee arthroplasty, thyroidectomy, and ventral hernia repair.
  • Construction of trends in risk-adjusted, standardized, smoothed rates for 6 outcomes: mortality, pneumonia, renal failure, surgical site infection, unplanned intubation, and urinary tract infection (UTI).

Main Results:

  • Overall adverse event rates: mortality 1.08%, pneumonia 1.44%, renal failure 0.67%, surgical site infection 5.28%, unplanned intubation 1.11%, UTI 1.86%.
  • Hepatectomy showed the most improvement across outcomes (36.2 events avoided/10,000 procedures).
  • Urinary tract infection (UTI) rates improved across the most procedures (98.9 events avoided/10,000 procedures).
  • Pancreatectomy demonstrated improved mortality, unplanned intubation, and UTI rates, but a significant increase in surgical site infection rates (p < 0.05).

Conclusions:

  • Hepatectomy outcomes improved most significantly.
  • Urinary tract infection rates showed the greatest improvement across procedures.
  • Increased surgical site infection rates following pancreatectomy necessitate urgent, focused quality improvement efforts.
