Postoperative delirium (POD) is a common neuropsychiatric disorder characterized by inattention, fluctuating levels of consciousness, and disorganized thinking. POD can have serious consequences, including institutionalization and death. Risk stratification may target prevention to individuals at greater risk of POD. The objective of this study was to identify all published POD risk prediction models (RPMs) and to compare them with regard to their clinical practicability and predictive and discriminative performance. PubMed and EMBASE were searched from inception to January 1, 2013, for articles describing POD RPMs. Studies were included if they presented data from a cohort study, examined one or more RPMs, examined POD as an outcome, and assessed the performance of the RPM(s). Thirty of 2,246 articles were included, and 37 RPMs were found. Sixteen and six studies described individuals who had undergone cardiovascular and orthopedic surgery, respectively. The Confusion Assessment Method (CAM) for the intensive care unit checklist was the most often used diagnostic method (65%), followed by the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition criteria (16%). Predictors most often used in RPMs were age (20), preoperative Mini-Mental State Examination score (10), and preoperative increased alcohol use (7). Thirty RPMs were not validated, three were validated internally, and four were validated externally. Size of the models was not associated with their discriminatory performance. Instead of creating steadily new RPMs, existing RPMs should be further tested, improved, and meta-analytically integrated. It may be too early to implement a particular PODRPM in clinical practice with confidence.

“…Known risk factors include poor preoperative functional status, cognitive impairment, depression, alcoholism, vascular disease, comorbidity, and older age. 4,[8][9][10][11][12][13][14][15][16] Delirium is associated with a poorer postoperative outcome and it prolongs the hospital stay. Furthermore long-term cognitive function of the patients who suffered from postoperative delirium can be impaired with a poor functional status.…”

Postoperative delirium, morbidity, and mortality in our elderly patients with secondary perionitis of colorectal origin is described. This is a chart-based retrospective analysis of 63 patients who were operated on at the University Hospital Basel from April 2001 to May 2004. Postoperative delirium occurred in 33%. Overall morbidity was 71.4%. Surgery-related morbidity was 43.4%. Mortality was 14.4%. There was no statistical significance between delirium, morbidity and mortality (P = 0.279 and P = 0.364). There was no statistically significant correlation between the analyzed scores (American Society of Anesthesiologists classification, Mannheimer Peritonitis Index, Acute Physiology and Chronic Health Evaluation score II, physiological and operative surgical severity and enumeration of morbidity and mortality score' or short 'cr-POSSUM') and postoperative delirium, morbidity or mortality. Postoperative delirium occurred in one-third of the patients, who seem to have a trend to higher morbidity. Even if the different scores already had proven to be predictive in terms of morbidity and mortality, they do not help the risk stratification of postoperative delirium, morbidity, or mortality in our collective population.

“…9 Despite the strength of the IQCODE, only a few studies have dealt with its usefulness for predicting postoperative delirium. 13,14 The results of this pilot study have prompted us to further investigate and compare the usefulness of the IQCODE and other cognitive screening tests for predicting postoperative delirium in a larger sample size. Additionally, the development and validation of a new informantbased questionnaire that is suitable for use as a screening test for postoperative delirium is being considered.…”

Background and Purpose Preexisting cognitive impairment is the strongest risk factor for delirium. We performed a pilot study to investigate whether the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), which is a good complement to direct cognitive testing, could be useful for predicting postoperative delirium in elderly patients. Methods Between June 2013 and May 2014, 37 patients aged 70 years or older underwent the Korean version of the Mini-Mental State Examination (K-MMSE) and completed the IQCODE (IQCODE-K) before elective spine surgery in the Spine Center at the Seoul National University Bundang Hospital. Delirium was assessed daily from the day after surgery until discharge. A Mann-Whitney U test was used to compare the K-MMSE scores and the IQCODE-K scores between the groups with and without postoperative delirium. Results A total of three of 37 (8.1%) patients developed delirium during their hospital stay. The K-MMSE scores were not different between the two groups (p=0.105), whereas the IQCODE-K scores of patients with delirium were significantly higher than those of patients without delirium (p=0.021), indicating greater cognitive and functional decline over the previous 10 years. Conclusions The IQCODE may be a suitable tool for assessing preoperative cognitive function and predicting postoperative delirium in elderly patients.
