Preoperative Psychological Evaluation Outcomes, Reasoning, and Demographic and Diagnostic Correlates.

Purpose: Little is known about associations between preoperative psychiatric, disordered eating, and substance use diagnoses with the clinical decision to require follow-up after the preoperative psychological evaluation. To determine the proportion of patients who require follow-up (no required follow-up (NFU), required follow-up (RFU), placed on hold (POH)) from the preoperative psychological evaluation, associations with diagnoses, and noted reasons for follow-up.
Materials and Methods: The sample included 508 patients (77.6% female; 64.4% White) pursuing bariatric metabolic surgery with completed psychological evaluations between August 2019 and December 2020 at a Midwest medical center. Patient demographics, psychological evaluation outcome and corresponding reasoning, and psychiatric, disordered eating, and substance use diagnoses were extracted from the health record. Descriptive and bivariate analyses determined associations between demographics and diagnoses with psychological evaluation outcomes and corresponding reasoning.
Results: The breakdown of psychological evaluation outcomes was 60.6% (n = 308) NFU, 38.4% (n = 195) RFU, and 1.0% (n = 5) POH. Demographic correlates of RFU included higher BMI, being single, lower educational attainment, unemployment, public/no insurance, and receiving multiple or any psychiatric diagnosis (all p-values < 0.05). Diagnostic correlates of RFU included anxiety, depression, not having a current trauma or stressor-related disorder, disordered eating, and substance use diagnoses (all p-values < 0.001). RFU/POH was primarily due to psychiatric (61%) reasons.
Conclusion: Higher rates of RFU were observed for patients with higher economic need and with psychiatric, disordered eating, or substance use diagnoses. Future work should establish preoperative programming to assist patients with addressing ongoing psychiatric concerns prior to bariatric metabolic surgery.
