Evaluation of a new mobile diagnostic imaging services at a tertiary Spinal Cord Rehabilitation Program during the COVID-19 pandemic

ABSTRACT

Background: As a standalone tertiary spinal cord rehabilitation program, our patients requiring diagnostic imaging during their inpatient stay need to be transported to an acute care hospital to receive these services. Over the course of inpatient rehabilitation, patients routinely travel to acute care hospitals for diagnostic imaging for surgical follow-up, musculoskeletal injuries, vascular complications such as deep vein thrombosis and other medical complications. Due to travel and wait time, patients typically miss at least a half day of therapy to attend imaging appointments. At the beginning of the COVID-19 pandemic, an urgent need arose to develop a new approach to diagnostic imaging due to a significant reduction in access to acute care diagnostic imaging and in order to reduce the risk of patient exposure to COVID-19. Objective: The goal of this initiative was to implement a new, mobile diagnostic imaging service that would minimize external travel during inpatient rehab, reduce risk of exposure to COVID-19, reduce lost therapy hours, while at least remaining cost-neutral. In order to evaluate this service, the costs and benefits associated with this mobile x-ray and ultrasound service were examined. Methods: With the support of Joint Department of Medical Imaging, our SCI rehab program partnered with STL Diagnostic Imaging to provide onsite x-ray and ultrasound imaging.The service began on May 11, 2020 and consisted of mobile x-ray imaging twice per week and mobile ultrasound scans once per week for two hours each. All imaging was conducted in patient rooms by STL technologists. Monthly STL billing costs were compared to estimated transportation costs for patients. Typical transportation costs range from $60-$284 depending on mode of transportation. Results: Between May 11, 2020 and January 28, 2021, 144 patients received 203 x-ray images over 67 x-ray days and 81 patients received 105 ultrasound scans over 37 ultrasound days. Over this timeframe, the approximate savings in transportation costs ranged from $7114 to $20,753. In addition, it is estimated that 225 - 450 lost therapy hours were avoided since patients did not have to travel for imaging and therefore avoided missing scheduled therapy appointments. Although not formally evaluated, physician, patient and nursing staff satisfaction regarding this new service has also been extremely positive. Conclusion: Although implemented out of necessity during the pandemic, this partnership to provide mobile diagnostic imaging has been cost-effective and beneficial to patients.
