Does preoperative impaired sensorium increase postoperative morbidity and mortality in patients undergoing nonemergent general surgical operations?
p-value: p=< .05
Preoperative impaired sensorium is an independent risk factor for postoperative morbidity and mortality in nonemergent general surgery, highlighting the importance of cognitive assessment in preoperative risk stratification.
Gajdos et al. (2014) conducted a cohort in Nonemergent general surgical operations (n=294,037). Preoperative impaired sensorium vs. No preoperative impaired sensorium was evaluated on Rates of postoperative complications and death (p=< .05). Preoperative impaired sensorium was associated with significantly elevated rates of postoperative complications and death following nonemergent general surgical operations (P < .05).
