The geriatric population has a greater incidence of postoperative delirium as compared to the rest of the general population. This paper will be a summation of the article submitted this year in the American Journal of Critical Care, Postoperative Delirium after Colorectal Surgery in Older Adults (Mangnall, Gallagher, & Stein-Parbury, 2011) in which postoperative delirium was evaluated by nursing researchers on patients 50 years of age and greater.

There were 54% women, 46% men, mean age was 71.81, and 64% were married. The researches then assessed these patients using the Confusion Assessment Method, an algorithmic tool, otherwise known as CAM for 72 hours post surgically. “Nurses, particularly in critical care and acute surgical units, have the most frequent contact with postoperative patients and therefore are in the best position to detect cognitive changes associated with delirium” (Milisen, Lemiengre, Braes, & Foreman, 2005).
