ImportanceThe health of the US population is decreasing, and novel strategies are needed to reverse the trajectory. The surgical episode may be an opportune time to screen for poor health behaviors and social needs, yet little is known about the feasibility or acceptability of such efforts.ObjectiveTo assess the feasibility and acceptability of a pilot program that engages patients in health behavior change and addresses unmet social needs at the time of surgery.Design, Setting, and, ParticipantsThis quality improvement study was conducted among 10 338 patients seen in a preoperative clinic for elective surgery between February 8 and August 31, 2021. Patients who received a referral for institutional resources were contacted via telephone to complete follow-up surveys 30 to 90 days after surgery and between July 1, 2021, and March 31, 2022.InterventionsImplementation of a tool to screen patients for smoking and food insecurity in a preoperative clinic. Those who screened positive were offered referrals for institutional resources. Telephone surveys were conducted with patients who accepted referrals to understand attitudes toward addressing health behaviors and social needs.Main Outcomes and MeasuresScreening and referral rates, patient-perceived acceptability of addressing health behaviors and social needs at the time of surgery, smoking cessation rates, and resolution of food insecurity.ResultsA total of 10 338 patients (6052 women [58.5%]; mean [SD] age, 56.5 [17.9] years) were evaluated in the preoperative clinic. Of the 10 338 patients, 7825 (75.7%) were successfully screened. Of the 641 identified smokers, 152 (23.7%) accepted a referral for smoking cessation counseling. Of the 181 identified patients with food insecurity, 121 (66.9%) accepted a referral for nonmedical needs assistance. On follow-up surveys, 64 of 78 smokers (82.1%) agreed that the preoperative appointment was an appropriate time to discuss smoking cessation, and 34 of 78 smokers (43.6%) reported quitting smoking. Similarly, 69 of 84 patients with food insecurity (82.1%) agreed it was a good or very good idea for health systems to address nonmedical needs at the time of surgery, and 27 patients (32.1%) reported no longer being insecure about food since their preoperative visit.Conclusions and RelevanceThis study suggests that it is feasible to address patients’ foundational health at the time of surgery. Most patients agreed that these interventions were appropriate during the perioperative period. These results support using the surgical episode as an opportunity to address foundational health.
