Helping spine surgeons detect pre-surgical psychological distress in complex spine patients: an observational pilot study.

Abstract

Retrospective analysis. Analysis of a standardized, pre-surgical psychological evaluation program for complex spine surgery. Adult spinal deformity (ASD) patients have a high rate of comorbid mental health conditions. Although there is a body of literature demonstrating the impact of psychological factors, including anxiety and depression, on spine surgery outcome, it is estimated that spine surgeons utilize a psychological assessment only about one third of the time prior to a patient's spine surgery. At this time, there is not a widely reported pre-surgical psychological evaluation program for ASD patients. 129 consecutive complex spine surgery candidates receiving a pre-surgical psychological evaluation were analyzed between January 1st 2014 and December 31st 2018. Based on the available literature and professional experience in our facility, a color code for patients was developed from Green (low psychological or psychosocial co-morbidity) to Red (high psychological or psychosocial co-morbidity). Univariate analysis was used to evaluate between color grades and demographics, mental health disorders and outcomes. 83% of complex spine patients had at least one psychological disorder or psychosocial barrier. Only 17% had a combination of realistic expectations for surgery, a good support plan, and were without a history of mental illness. The pre-surgical psychological color criteria were validated in showing higher rates of major depression, anxiety disorder, and bipolar disorder in moderate to severe color grades (p < .001) in addition to higher PHQ-9 and GAD-7 scores (p < .001). Patients having a more severe color grade had lower rates of a discharge home and were taking higher morphine equivalent dosages (MEDs) at their six-month follow-up, though both did not reach statistical significance (p = .07 and p = .08; respectively). A comprehensive pre-surgical psychological evaluation may be beneficial to risk stratify and counsel patients being evaluated for surgical reconstruction of adult spinal deformities. 3.
