Introduction: The use of telemedicine significantly increased during the COVID-19 pandemic and has become an integral component of many clinics. The impact of telemedicine on greenhouse gas emissions is poorly defined. The aim of this study was to evaluate the impact of telehealth on carbon emissions for patients of a neurosurgery spine clinic.
Methods: A retrospective analysis of all patients who had encounters with a neurosurgery spine clinic between Jan 2021 and Nov 2021 was performed. Carbon saving analyses were performed on various patient subgroups.
Results: A total of 6,797 patients were included with 71% having telehealth appointments. Without telehealth, 4480 patients would have driven to clinic and 322 would have flown. This group yielded an overall 495,467 kg CO2 in savings, with 276,412 kg CO2 saved by driving and the remainder by flying. Carbon savings from local patients alone was 42,237 kg CO2. In addition, all patients seen in the clinic from across the United States used telehealth, then this would have generated an additional 167,495 kg CO2 savings for a total of 662,962 kg CO2 savings. If our telehealth patient cohort had instead traveled for in-person visits, then 2970 trees would have been needed to offset the carbon waste generated.
Conclusion : Telehealth is an effective tool in reducing overall carbon emissions. Additional investigation into the use of telehealth in neurosurgical clinics is warranted.
