Key result
Preoperative mild cognitive impairment (MCI) did not predict post-operative delirium among elderly patients undergoing elective surgery.

Does preoperative mild cognitive impairment predict post-operative delirium in elderly patients undergoing elective surgery?
Preoperative mild cognitive impairment is highly incident in elderly surgical patients but does not appear to predict post-operative delirium.
Answers are grounded in this paper and cite their sources.
Preoperative MCI screening should not guide delirium prophylaxis in elective surgery; leaves open its predictive value in other settings.
Post-operative delirium in elderly patients is associated with higher mortality and longer lengths of stay. This prospective observational study investigated the incidences of preoperative mild cognitive impairment (MCI) and post-operative delirium among elderly patients undergoing elective surgery at the authors’ institution, the relationship between MCI and delirium, and the impact of delirium on surgical morbidity and lengths of stay. The authors found that although MCI did not predict post-operative delirium, the high incidence of MCI in elective surgery patients warrants further study.

Newman et al. (2014) conducted an observational in Elderly patients undergoing elective surgery. Preoperative mild cognitive impairment (MCI) was evaluated on Post-operative delirium. Preoperative mild cognitive impairment (MCI) did not predict post-operative delirium among elderly patients undergoing elective surgery.
