Abstract
Background
Surgical resection is a mainstay of treatment for colorectal cancer (CRC). Minimally invasive surgery (MIS) has been shown to have improved outcomes compared to open procedures for colorectal malignancy. While use of MIS has been increasing, there remains large variability in its implementation at the hospital and patient level.
Objective
The purpose of this study was to identify disparities in sex, race, location, patient income status, insurance status, hospital region, bed size and teaching status for the use of MIS in the treatment of CRC.
Methods
This was a retrospective cohort study using the Nationwide Inpatient Sample Database. Between 2008 and 2017, there were 412,292 hospitalizations of adult patients undergoing elective colectomy for CRC. The primary outcome was use of MIS during hospitalization.
Results
Overall, the frequency of open colectomies was higher than MIS (56.56% vs. 43.44%). Black patients were associated with decreased odds of MIS use during hospitalization compared to White patients (OR 0.921, p = 0.0011). As the county population where patients resided decreased, odds of MIS also significantly decreased as compared to central counties of metropolitan areas. As income decreased below the reference of $71,000, odds of MIS also significantly decreased. Medicaid and uninsured patients had decreased odds of MIS use during hospitalization compared to private insurance (OR 0.751, p < 0.0001 and OR 0.629, p < 0.0001 respectively). Rural and urban non-teaching hospitals were associated with decreased odds of MIS as compared to urban teaching hospitals (OR 0.523, p < 0.0001 and OR 0.837, p < 0.0001 respectively). Hospitals with a small bed size were also associated with decreased MIS during hospitalizations (OR 0.888, p < 0.0001).
Conclusions
Marked hospital level and socioeconomic disparities exist for utilization of MIS for colorectal cancer. Strategies targeted at reducing these gaps have the potential to improve surgical outcomes and cancer survival.
