    Identifying Older Adults at Risk of Delirium Following Elective Surgery: A Systematic Review and Meta-Analysis

    Watt J, Tricco AC, Talbot-Hamon C, Rios P, Grudniewicz A, Wong C, Sinclair D. Straus SE. Identifying Older Adults at Risk of Delirium Following Elective Surgery: A Systematic Review and Meta-Analysis. Journal of General Internal Medicine. 2018;33(4):500-509. DOI: 10.1007/s11606-017-4204-x.

     

    Altmetric:

     

    Bottom Line:

    • Potentially modifiable prognostic factors including frailty, psychotropic medication use, smoking status, and the availability of caregiver support in the perioperative period should be studied further to improve patient outcomes
    • Even in the setting of elective surgery, delirium was common (1 in 6 older adults) and associated with other adverse postoperative complications including death

    Impact:

    • This review aims to improve clinician-patient discussions on informed consent prior to elective surgery in older adults and to help researchers and policy-makers develop interventions that effectively target modifiable risk factors for post-operative complications

    Identifying Older Adults at Risk of Harm Following Elective Surgery: A Systematic Review and Meta-Analysis

    Watt J, Tricco AC, Talbot-Hamon C, Rios P, Grudniewicz A, Wong C, Sinclair D. Straus SE. Identifying Older Adults at Risk of Harm Following Elective Surgery: A Systematic Review and Meta-Analysis. BMC Medicine. 2018;16(1):2. DOI: 10.1186/s12916-017-0986-2.

     

    Altmetric:

     

    Bottom Line:

    • Postoperative complications were common (1 in 4 older adults). Frailty, which is often synonymous with someone's biological age, was associated with increased risk of postoperative complications; however, neither chronological age nor ASA status were associated this outcome. Potentially modifiable prognostic factors (e.g. frailty) should be studied further to improve patient outcomes

    Impact:

    • This review aims to improve clinician-patient discussions on informed consent prior to elective surgery in older adults and to help researchers and policy-makers develop interventions that effectively target modifiable risk factors for post-operative complications
