Abstract

Study objective

The growing number of older persons undergoing surgery are at a higher risk of neurocognitive disorder due to multimorbidity and age-related changes. Previous reviews estimated postoperative neurocognitive disorder or cognitive dysfunction (POCD) prevalence without accounting for the sample size or study quality. The prevalence of POCD in this population requires further investigation. This systematic review and meta-analysis applies systematic weighting to estimate the pooled prevalence of POCD in older non-cardiac surgical patients.

Design

Systematic review and meta-analysis.

Setting

MEDLINE, MEDLINE ePub, Embase, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews for relevant articles.

Patients

Non-cardiac surgical patients aged ≥60 years old.

Interventions

Perioperative cognitive assessments.

Measurement

The primary outcome was the prevalence of POCD.

Main results

Thirty-nine studies (n = 12,921) were included with mean age of 70.0 ± 8.9 years and 44.3 % women. The overall prevalence of POCD was 23 % (95 % CI: 20 %, 27 %) at day 7, 16 % (95 % CI: 7 %, 25 %) at 1 month, 10 % (95 % CI: 8 %, 13 %) at 3 months and 3 % (95 % CI: 2 %, 4 %) at 1 year. Our meta-regression showed a higher prevalence of POCD in abdominal surgeries at day 7 (β = 0.13, 95 % CI: 0.03–0.22, P = 0.01) and 3 months (β = 0.49, 95 % CI: 0.40–0.58, P < 0.001), versus orthopedic surgeries.

Conclusions

The overall prevalence of POCD in older non-cardiac surgical populations was 23 %, 16 %, 10 %, and 3 % at day 7, 1 month, 3 months, and 1 year, respectively. Abdominal surgery had a higher prevalence of POCD than orthopedic surgery. The substantial risk of POCD calls for cognitive screening, risk mitigation and interventions to improve surgical outcomes. Through routine preoperative cognitive screening and addressing modifiable risk factors, the incidence and impact of POCD can be markedly reduced, enhancing patient outcomes and recovery.

期刊介绍： The Journal of Clinical Anesthesia (JCA) addresses all aspects of anesthesia practice, including anesthetic administration, pharmacokinetics, preoperative and postoperative considerations, coexisting disease and other complicating factors, cost issues, and similar concerns anesthesiologists contend with daily. Exceptionally high standards of presentation and accuracy are maintained. The core of the journal is original contributions on subjects relevant to clinical practice, and rigorously peer-reviewed. Highly respected international experts have joined together to form the Editorial Board, sharing their years of experience and clinical expertise. Specialized section editors cover the various subspecialties within the field. To keep your practical clinical skills current, the journal bridges the gap between the laboratory and the clinical practice of anesthesiology and critical care to clarify how new insights can improve daily practice.
