HbSS poor vaccine responders were at increased future recurrence risk for ACS (p=0.003), pneumonia (p=0.036) or both (p=0.011), compared to good vaccine responders.
Seniors resembled better cardiac complications (p < 0.05) and both resident and senior anesthesiologists failed to resemble the ACS calculator in assessing return to the operating room and pneumonia (p < 0.05).
