Operative volume in colon surgery: a matched cohort analysis

Area of Science:

• Colorectal Surgery
• Health Services Research
• Surgical Outcomes

Background:

• Previous research linked higher colectomy volumes to lower mortality.
• The impact of surgical volume on resource utilization remained less understood.

Purpose of the Study:

• To investigate the association between colectomy procedure volume and key healthcare metrics.
• To analyze the relationship between surgeon/hospital volume, costs, complications, length of stay, and mortality.

Main Methods:

• Utilized data from the National Inpatient Sample for analysis.
• Employed propensity score matching to control for confounding factors.

Main Results:

• Higher colectomy volumes (surgeon and hospital) were associated with lower costs, fewer complications, and shorter length of stay.
• High-volume surgeons demonstrated significantly fewer complications, shorter length of stay, and lower costs compared to low-volume surgeons.
• No significant difference in mortality was observed based on surgeon volume.

Conclusions:

• Individual surgeon volume is a significant factor influencing length of stay and healthcare costs in colectomy procedures.
• While disease burden is a primary driver, surgeon experience impacts resource utilization and patient outcomes beyond mortality.
