Study Design. Retrospective cohort review. Objective. The objective of this study was to identify depression using the Mental Component Score (MCS-12) of the Short Form-12 (SF-12) survey and to correlate with patient outcomes. Summary of Background Data. The impact of preexisting depressive symptoms on health-care related quality of life (HRQOL) outcomes following lumbar spine fusion is not well understood. Methods. Patients undergoing lumbar fusion between one to three levels at a single center, academic hospital were retrospectively identified. Patients under the age of 18 years and those undergoing surgery for infection, trauma, tumor, or revision, and less than 1-year follow-up were excluded. Patients with depressive symptoms were identified using an existing clinical diagnosis or a score of MCS-12 less than or equal to 45.6 on the preoperative SF-12 survey. Absolute HRQOL scores, the recovery ratio (RR) and the percent of patients achieving minimum clinically important difference (MCID) between groups were compared, and a multiple linear regression analysis was performed. Results. A total of 391 patients were included in the total cohort, with 123 (31.5%) patients reporting symptoms of depression based on MCS-12 and 268 (68.5%) without these symptoms. The low MCS-12 group was found to have significantly worse preoperative Oswestry disability index (ODI), visual analogue scale back pain (VAS Back) and visual analogue scale leg pain (VAS Leg) scores, and postoperative SF-12 physical component score (PCS-12), ODI, VAS Back, and VAS Leg pain scores (P < 0.05) than the non-depressed group. Finally, multiple linear regression analysis revealed preoperative depression to be a significant predictor of worse outcomes after lumbar fusion. Conclusion. Patients with depressive symptoms, identified with an MCS-12 cutoff below 45.6, were found to have significantly greater disability in a variety of HRQOL domains at baseline and postoperative measurement, and demonstrated less improvement in all outcome domains included in the analysis compared with patients without depression. However, while the improvement was less, even the low MCS-12 cohort demonstrated statistically significant improvement in all HRQOL outcome measures after surgery. Level of Evidence: 3
Study Design: This was a prospective cohort study. Objective: The objective of this study was to design and test a novel spine neurological examination adapted for telemedicine. Summary of Background Data: Telemedicine is a rapidly evolving technology associated with numerous potential benefits for health care, especially in the modern era of value-based care. To date, no studies have assessed whether. Methods: Twenty-one healthy controls and 20 patients with cervical or lumbar spinal disease (D) were prospectively enrolled. Each patient underwent a telemedicine neurological examination as well as a traditional in-person neurological examination administered by a fellowship trained spine surgeon and a physiatrist. Both the telemedicine and in-person tests consisted of motor, sensory, and special test components. Scores were compared via univariate analysis and secondary qualitative outcomes, including responses from a satisfaction survey, were obtained upon completion of the trial. Results: Of the 20 patients in the D group, 9 patients had cervical disease and 11 patients had lumbar disease. Comparing healthy control with the D group, there were no significant differences with respect to all motor scores, most sensory scores, and all special tests. There was a high rate of satisfaction among the cohort with 92.7% of participants feeling “very satisfied” with the overall experience. Conclusions: This study presents the development of a viable neurological spine examination adapted for telemedicine. The findings in this study suggest that patients have comparable motor, sensory, and special test scores with telemedicine as with a traditional in-person examination administered by an experienced clinician, as well as reporting a high rate of satisfaction among participants. To our knowledge, this is the first telemedicine neurological examination for spine surgery. Further studies are warranted to validate these findings.
