Abstract
BACKGROUND: Emergency colon cancer surgery is associated with increased mortality and complication risk, which can be due to differences in the organization of hospital care. This study aimed. OBJECTIVE: To explore which structural factors in the preoperative, perioperative and postoperative periods influence outcomes after emergency colon cancer surgery. METHODS: An observational study was performed in 30 Dutch hospitals. Medical records from 1738 patients operated in the period 2012 till 2015 were reviewed on the type of referral, intensive care unit (ICU) level, surgeon specialization and experience, duration of surgery and operating room time, blood loss, stay on specialized postoperative ward, complication occurrence, reintervention and day of surgery and linked to case-mix data available in the Dutch Colorectal Audit. Multivariate logistic regression analysis was used to estimate the influence of these factors on 30-day mortality, severe complication and failure to rescue (FTR), after adjustment for case-mix. RESULTS: Patients operated by a non-Gastro intestinal/oncology specialized surgeon have significantly increased mortality (Odds Ratio (OR) 2.28 [95% confidence interval (95% CI) 1.23-4.23]) and severe complication risk (OR 1.61 [95% CI 1.08-2.39]). Also, duration of stay in the operating room was significantly associated with increased risk on severe complication (OR 1.03 [95% CI 1.01-1.06]). Patients admitted to a non-specialized ward have significantly increased mortality (OR 2.25 [95% CI 1.46-3.47]) and FTR risk (OR 2.39 [95% CI 1.52-3.75]). A low ICU level (basic ICU) was associated with a lower severe complication risk (OR 0.72 [95% CI 0.52-1.00]). Surgery on Tuesday was associated with a higher mortality risk (OR 2.82 [95% CI 1.24-6.40]) and a severe complication risk (OR 1.77, [95% CI 1.19-2.65]). CONCLUSION: This study identified a non-specialized surgeon and ward, operating room, time and day of surgery to be risk factors for worse outcomes in emergency colon cancer surgery.
