Telemedicine in Spine Surgery: Outcomes for 138 Patients With Virtual Preoperative Assessment Compared to Historical Controls.

ABSTRACT

INTRODUCTION: COVID-19 has accelerated the use of telemedicine in all aspects of health care delivery, including initial surgical evaluation. No existing literature investigates the safety and efficacy of telemedicine to preoperatively evaluate spine surgery candidates. Our objectives were (1) Compare the change in visual analogue scale (VAS) scores between the telemedicine preoperative visit and in-person preoperative visit groups. (2) Compare the average surgical time, estimated blood loss (EBL), length of hospital stay (LOS), rates of intraoperative complications, rates of readmission, and rates of reoperation between the telemedicine preoperative visit and in-person preoperative visit groups. METHODS: The previously stated metrics were collected for 276 patients, 138 who were exclusively evaluated preoperatively with telemedicine and 138 historical controls who were evaluated preoperatively in person. We used χ2 and independent samples t tests to determine significance. RESULTS: There were no significant differences in the mean change in VAS scores (-2.7 ± 3.1 telemedicine vs. -2.2 ± 3.7 in-person, P = 0.317), mean percentage change in VAS scores (-40.5% ± 54.3% vs. -39.5% ± 66.6%, P = 0.811), mean surgical time (2.4 ± 1.4 hours vs. 2.3 ± 1.3 ours, P = 0.527), mean EBL (150.4 ± 173.3 mL vs. 156.7 ± 255.0 mL, P = 0.811), mean LOS (3.3 ± 2.4 days vs. 3.3 ± 2.5 days, P = 0.954), intraoperative complication rates (0.7% vs. 1.4%, P = 0.558), reoperation rates (7.9% vs. 4.3%, P = 0.208), or readmission rates (10.1% vs. 5.1%, P = 0.091) between the telemedicine preoperative visit and in-person preoperative visit groups. CONCLUSIONS: Preoperative evaluation via telemedicine leads to the same short-term surgical outcomes as in-person evaluation with no increased risk of surgical complications.
