Lumbar fusion during the COVID-19 pandemic: greater rates of morbidity and longer procedures.

Background: The coronavirus disease 2019 (COVID-19) pandemic has altered the standard of care for spine surgery in many ways. However, there is a lack of literature evaluating the potential changes in surgical outcomes and perioperative factors for spine procedures performed during the pandemic. In particular, no large database study evaluating the impact of the COVID-19 pandemic on spine surgery outcomes has yet been published. Therefore, the aim of this study was to evaluate the impact of the COVID-19 pandemic on perioperative factors and postoperative outcomes of lumbar fusion procedures. Methods: This retrospective cohort study utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, which was queried for all adult patients who underwent primary lumbar fusion in 2019 and 2020. Patients were grouped into cohorts based on 2019 (pre-pandemic) or 2020 (intra-pandemic) operation year. Differences in 30-day readmission, reoperation, and morbidity rates were evaluated using multivariate logistic regression. Differences in total relative value units (RVUs), RVUs per minute, and total operation time were evaluated using quantile (median) regression. Odds ratios (OR) for length of stay were estimated via negative binomial regression. Results: A total of 27,446 patients were included in the analysis (12,473 cases in 2020). Unadjusted comparisons of outcomes revealed that lumbar fusions performed in 2020 were associated with higher rates of morbidity, pneumonia, bleeding transfusions, deep venous thrombosis (DVT), and sepsis. 2020 operation year was also associated with longer length of hospital stay, less frequent non-home discharge, higher total RVUs, and higher RVUs per minute. After adjusting for baseline differences in regression analyses, the differences in bleeding transfusions, length of stay, and RVUs per minute were no longer statistically significant. However, operation year 2020 independently predicted morbidity, pneumonia, DVT, and sepsis. In terms of perioperative variables, operation year 2020 predicted greater operative time, non-home discharge, and total RVUs. Conclusions: Lumbar fusion procedures performed amidst the COVID-19 pandemic were associated with poorer outcomes, including higher rates of morbidity, pneumonia, DVT, and sepsis. In addition, surgeries performed in 2020 were associated with longer operative times and less frequent non-home discharge disposition.

Telemedicine in Spine Patients: Utilization and Satisfaction Remain High Even After Easing of COVID-19 Lockdown Restrictions.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The objectives of the present study were to 1) define telemedicine utilization rates during and after the initial height of the COVID-19 lockdown period and 2) determine patient satisfaction with telemedicine during and after the initial height of the COVID-19 lockdown period for spine patients at an orthopedic specialty hospital. SUMMARY OF BACKGROUND DATA: Previous studies have shown high patient satisfaction with telemedicine during the initial height of the COVID-19 pandemic. However, there exists limited data about spine telemedicine utilization and patient satisfaction after the reopening of in-person office visits and easing of restrictions on elective surgical care. METHODS: All patients who had an in-person or telemedicine visit at an urban tertiary specialty hospital from April 1, 2020 to April 15, 2021 were identified. Rates of overall telemedicine utilization over time were delineated. Patient satisfaction with telemedicine, as assessed through a series of questionnaires, was also evaluated over time. RESULTS: Overall, 60,368 patients were identified. Of these, 19,568 patients (32.4%) had a telemedicine visit. During the peak initial coronavirus lockdown period, rate of overall telemedicine utilization on average was greater than 90%. After the peak period, the rate of overall telemedicine utilization on average was at approximately 29% of all visits per month. The percentage of patients who would have been definitely comfortable if the telemedicine visit had been in-person increased over the entire study period (P<0.001). Despite this, patient satisfaction based on survey responses remained statistically similar throughout the study period (P>0.05). CONCLUSION: The rate of telemedicine utilization in spine patients remains high, at approximately 1/3 of all visits, even after the initial peak coronavirus lockdown period. In addition, patient satisfaction with telemedicine remained consistent throughout the study period, regardless of pandemic restrictions on in-person visits. LEVEL OF EVIDENCE: III.

Appropriate Telemedicine Utilization in Spine Surgery: Results From a Delphi Study.

STUDY DESIGN: Delphi expert panel consensus. OBJECTIVE: To obtain expert consensus on best practices for appropriate telemedicine utilization in spine surgery. SUMMARY OF BACKGROUND DATA: Several studies have shown high patient satisfaction associated with telemedicine during the COVID-19 peak pandemic period as well as after easing of restrictions. As this technology will most likely continue to be employed, there is a need to define appropriate utilization. METHODS: An expert panel consisting of 27 spine surgeons from various countries was assembled in February 2021. A two-round consensus-based Delphi method was used to generate consensus statements on various aspects of telemedicine (separated as video visits or audio visits) including themes, such as patient location and impact of patient diagnosis, on assessment of new patients. Topics with ≥75% agreement were categorized as having achieved a consensus. RESULTS: The expert panel reviewed a total of 59 statements. Of these, 32 achieved consensus. The panel had consensus that video visits could be utilized regardless of patient location and that video visits are appropriate for evaluating as well as indicating for surgery multiple common spine pathologies, such as lumbar stenosis, lumbar radiculopathy, and cervical radiculopathy. Finally, the panel had consensus that video visits could be appropriate for a variety of visit types including early, midterm, longer term postoperative follow-up, follow-up for imaging review, and follow-up after an intervention (i.e., physical therapy, injection). CONCLUSION: Although telemedicine was initially introduced out of necessity, this technology most likely will remain due to evidence of high patient satisfaction and significant cost savings. This study was able to provide a framework for appropriate telemedicine utilization in spine surgery from a panel of experts. However, several questions remain for future research, such as whether or not an in-person consultation is necessary prior to surgery and which physical exam maneuvers are appropriate for telemedicine.Level of Evidence: 4.

Early Peri-operative Outcomes Were Unchanged in Patients Undergoing Spine Surgery During the COVID-19 Pandemic in New York City.

BACKGROUND: Healthcare resources have been greatly limited by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic halting non-essential surgical cases without clear service expansion protocols. QUESTIONS/PURPOSES: We sought to compare the peri-operative outcomes of patients undergoing spine surgery during the SARS-CoV-2 pandemic to a matched cohort prior to the pandemic. METHODS: We identified a consecutive sample of 127 adult patients undergoing spine surgery between March 9, 2020, and April 10, 2020, corresponding with the state of emergency declared in New York and the latest possible time for 1-month surgical follow-up. The study group was matched one-to-one based on age, gender, and body mass index with eligible control patients who underwent similar spine procedures prior to the SARS-CoV-2 outbreak. Surgeries performed for infectious or oncologic indications were excluded. Intra- and post-operative complication rates, re-operations, hospital length of stay, re-admissions, post-operative visit format, development of post-operative fever and/or respiratory symptoms, and SAR-CoV2 testing. RESULTS: A total of 254 patients (127 SARS-CoV-2 pandemic, 127 matched controls) were included. One hundred fifty-eight were male (62%), and 96 were female (38%). The mean age in the pandemic group was 59.8 ± 13.4 years; that of the matched controls was 60.3 ± 12.3. All patients underwent general anesthesia and did not require re-intubation. There were no significant differences in 1-month post-operative complication rates (16.5% pandemic vs. 12.6% control). There was one death in the pandemic group. No patients tested positive for the virus. CONCLUSION: This study represents the first report of post-operative outcomes in a large group of spine surgical patients in an area heavily affected by the SARS-CoV-2 pandemic.
