Post-operative Functional Disability in Unrecognized Cognitive Impairment (POF) Study
Post-operative Functional Disability in Unrecognized Cognitive Impairment (POF) Study: an Observational Cohort Study in Patients Undergoing Non-cardiac Surgery
Study Overview
Status
Conditions
Detailed Description
The primary aim of this study is to (1) determine the prevalence of CI preoperatively in older surgical adults using virtual or telephone cognitive instruments, (2) determine the diagnostic accuracy of the AD8, CDC single cognitive question, and T-MoCA against the TICS-M, and (3) compare the trajectory of preoperative and postoperative outcomes between those with and without CI. The outcomes include functional disability, IADL, sleep disturbances, quality of health, frailty, pain and depression.
In a preoperative assessment 1-30 days prior to their scheduled surgery, patients will be asked via telephone to complete TICS-M and T-MoCA and an online questionnaire, including the AD8, CDC single cognitive question, World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), IADL, EuroQol 5 Dimension (EQ-5D-5L), Geriatric Depression Scale (GDS), 5-item FRAIL questionnaire, (FRAIL), visual analog pain scale (VAS pain), Single-item Sleep Quality Scale (SQS), Pittsburgh Sleep Quality Index (PSQI), and STOP questionnaire. These questionnaires will be repeated at follow-up visits at 30-, 90-, and 180-days post-surgery. At the hospital on post-operatively days 1-3, the Confusion Assessment Method (CAM), SQS, and VAS pain will be administered during the in-person visit. Chart review of delirium will also be conducted during patients' stay at the hospital.

Primary Outcome Measures

Time Frame: Pre-surgery, 30-, 90- and 180-days post-surgery

|
Prevalence of cognitive impairment via remote (virtual/telephone) assessment
Time Frame: Pre-surgery, 30-, 90- and 180-days post-surgery
|
Prevalence of cognitive impairment via remote (virtual/telephone) assessment as detected by the CDC Single Cognitive Question.
The CDC Single Cognitive Question is a yes/no question where answers of yes indicate cognitive impairment.
|
Pre-surgery, 30-, 90- and 180-days post-surgery
|
The diagnostic accuracy (sensitivity, specificity, and AUC)
Time Frame: Pre-surgery
|
The diagnostic accuracy (sensitivity, specificity, and AUC [Area under the Receiver Operating Characteristic Curve (ROC)]) of the T-MoCA, AD8, and CDC Single Cognitive Question compared against the TICS-M.
|
Pre-surgery
|
The trajectories and prevalence or incidence of patient-reported outcomes
Time Frame: Pre-surgery, 30-, 90- and 180-days post-surgery
|
The trajectories and prevalence or incidence of functional disability as measured through the WHODAS 2.0 (World Health Organization Disability Assessment Schedule 2.0) in participants with CI vs those without.
A five-point rating scale is used for each question (none = 0, mild = 1, moderate = 2, severe = 3, extreme/cannot do = 4), and a higher WHODAS score indicates greater disability.
|
