Partial COVID-19 vaccination associated with reduction in postoperative mortality and SARS-CoV-2 infection

BACKGROUND: There are currently no data to guide decisions about delaying surgery to achieve full vaccination. METHODS: We analyzed data from patients undergoing surgery at any of the 1,283 VA medical facilities nationwide and compared postoperative complication rates by vaccination status. RESULTS:...

Sumario:BACKGROUND: There are currently no data to guide decisions about delaying surgery to achieve full vaccination. METHODS: We analyzed data from patients undergoing surgery at any of the 1,283 VA medical facilities nationwide and compared postoperative complication rates by vaccination status. RESULTS: Of 87,073 surgical patients, 20% were fully vaccinated, 15% partially vaccinated, and 65% unvaccinated. Mortality was reduced in full vaccination vs. unvaccinated (Incidence Rate Ratio 0.77, 95% CI [0.62, 0.94]) and partially vaccinated vs. unvaccinated (0.75 [0.60, 0.94]). Postoperative COVID-19 infection was reduced in fully (0.18 [0.12, 0.26]) and partially vaccinated patients (0.34 [0.24, 0.48]). Fully vaccinated compared to partially vaccinated patients, had similar postoperative mortality (1.02, [0.78, 1.33]), but had decreased COVID-19 infection (0.53 [0.32, 0.87]), pneumonia (0.75 [0.62, 0.93]), and pulmonary failure (0.79 [0.68, 0.93]). CONCLUSIONS: Full and partial vaccination reduces postoperative complications indicating the importance of any degree of vaccination prior to surgery.
