Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For Phase 1, 211 randomly selected patients 65 years of age or older of either gender will be enrolled presenting to the Brigham and Women's Hospital Weiner Center for Preoperative Evaluation (CPE) scheduled for elective joint replacement surgery. The Brigham and Women's Hospital performs more than 600 joint replacement procedures each year in patients 65 years of age or older. This is the age range where cognitive impairment becomes prevalent and postoperative cognitive and non-cognitive morbidity is common. Exclusion criteria will be patients diagnosed with dementia or cognitive impairment; scheduled for a procedure affecting the brain or cerebrovasculature (i.e. intracranial neurosurgery, carotid endarterectomy, cardiac surgery); planned to go to an ICU postoperatively; with uncorrected vision or hearing impairment (who cannot see the pictures or read or hear instructions); unable to use their dominant hand (limited ability to draw); and/or unable to speak, read or understand English. The investigators will use the CPE computerized scheduling system, which is updated continuously in real time and captures relevant information such as age and procedure to identify potential subjects. When patients check in with the receptionist for their appointment they will be notified that they may be eligible to participate in a study involving patients 65 years of age or older. The receptionist will then provide them with a brochure about the study that includes information about the purpose of the study, the risks to the patient, and potential benefits to society. The patient will then be asked if they are willing to speak with one of the study investigators and only those patients that agree to speak with a study investigator will be approached. A member of the study team will then contact the patient and verify that they satisfy the inclusion criteria and discuss the goals and risks of the study and ask them to participate. After all questions have been answered and the patient has had an opportunity to read the consent form, written consent will be obtained. After obtaining consent the patient will be interviewed by a member of the study team to obtain information about their years of education and self-reported functional status according to standardized scales for basic and instrumental activities of daily living (ADLs and IADLs, respectively). Grip strength as an index of frailty and mood assessed with the Geriatric Depression Scale-Short (GDS). An investigator will also administer a survey to assess the patient's perspective about the importance of preoperative cognitive screening. Information about ASA physical status, medications, and Charlson comorbidity index will be extracted subsequently from the patient's electronic medical record and patient interview. The patient will then be administered the MiniCog a simple cognitive screening tools that take just 2-4 min to complete and has little or no education, language, or race bias. During this phase of the project, a trained study team member will administer the test in the quiet of the evaluation room. The practitioner conducting the actual preoperative evaluation will be blinded to the cognitive test results and will complete a questionnaire about the patient's cognitive status based on their interactions during the visit. A trained, blinded member of the study team will score the test. Discharge to place other than home will be used as the primary outcome to determine the relationship between pre-existing cognitive impairment and patient outcome (Aim 2). As a secondary outcome delirium will be assessed once per day on postoperative days 1, 2, and 3 by a member of the study team using the Confusion Assessment Method (CAM) a well-validated measure of delirium in surgical patients. Other secondary outcomes that will be evaluated will include the use of restraints, hospital length of stay (LOS), complications (including in-hospital falls), 30 d readmission rate, and 30 d, 6 month, 1 year and 5 year mortality. Data will be extracted from the medical record and the BWH Balanced Scorecard. Phase 2 will examine the feasibility of implementing routine structured cognitive screening for elective surgical procedures into a busy preoperative evaluation center. 500 patients will be enrolled according to the criteria outlined above and ask CPE practitioners to administer the structured cognitive screen to all patient ≥ 65 years of age scheduled for a surgical procedure as part of their routine preoperative evaluation. A study team member will train the CPE staff in administration of the MiniCog prior to beginning this phase of the study; the test will be administered as part of the routine CPE visit. Outcome measures will be rate of successful testing (a score-able test), and impact of testing on patient flow. The latter will be obtained by extracting and comparing data from the CPE's computerized patient flow tracking system on time spent with a provider in a preoperative evaluation room and total duration of the CPE visit (check-in time to departure time) between enrolled subjects and age and procedure matched patients seen in the CPE the previous year.
