e21687 Background: The American College of Surgeons and American Geriatrics Society recommend a geriatric/frailty assessment (GA) in the preoperative evaluation. We previously reported the development and implementation of the electronic Rapid Fitness Assessment (eRFA) in geriatric clinics. The eRFA captures data on multiple GA domains, including functional activity, social support, emotional well-being, weight loss, polypharmacy, and cognitive function. We now report the feasibility of clinical implementation of the eRFA in diverse thoracic surgery outpatient settings. Methods: Over 5 months, the eRFA was implemented until used by 5 surgeons in 2 outpatient clinics. All patients presenting for initial consultation were to complete the self-reported components of the eRFA by themselves or with the help of caregivers using a tablet or desktop computer, before coming to the clinic or in the clinic. A nurse performed the timed “get up and go” test and MiniCog test. A summary report was prepared for the clinician by the time of the encounter, and the data were stored in a database and as part of the electronic medical record. Time to complete the eRFA was recorded. Results: Since initiation in 9/2016, 78% of patients (65/83; median age, 71 [range, 20-88]; 31F:34M) completed the eRFA at initial consultation with a thoracic surgeon. Median time to complete was 9 min (range, 2-50); 75% of surveys were completed by the patient alone, 23% with a caregiver, and 3% by a caregiver alone. A large number of geriatric syndromes were uncovered: 26% of patients (17/65) had abnormalities in word recall, clock drawing, and/or timed “get up and go”; 41% (27/65) needed assistance with activities of daily living; 9% needed a cane or other support to ambulate; and 26% had at least 1 fall in the last year. Conclusions: Administration of the eRFA, an electronic assessment of patient frailty, is feasible in the initial evaluation of thoracic surgery patients. Future steps include characterization of functional reserve of patients considered for surgery, creation of prognostic models, and development of clinical trials to assess means of improving outcomes in this population of patients at risk.
