BackgroundDeep brain stimulation (DBS) is an important treatment for Parkinson's disease, tremor and dystonia in appropriately selected patients. The Canada Health Act emphasizes equity and "reasonable access to medically necessary hospital and physician services." How to define "reasonable access" has not been well studied. We aimed to assess access to DBS implantation surgery and to determine the time required from initial assessment through to surgery and which step(s) delay the implantation.MethodsDBS implants from 2016 to 2023 at the University of Alberta were analyzed. The neurologists' decision to proceed with DBS marks the start of the workup. The time required to see a neurosurgeon, psychiatrist, neuropsychologist and healthcare allies and to receive DBS surgery was assessed. The impact of COVID-19 was studied.ResultsThe total time from starting the workup to DBS surgery was 387.76 ± 125.19 days prior to COVID-19, and marked delay occurred during and post-COVID-19 (840.15 ± 165.41 days and 839.78 ± 300.66 days, respectively). Most workups were done within 6 months pre-COVID-19, although a big range existed due to variable factors. The longest delay to surgery was from consent to DBS implantation, owing to a lack of operative time. There has not been a recovery post-pandemic.ConclusionsTime to DBS implantation surgery from initial decision is lengthy and more than doubled over the course of the COVID-19 pandemic. The biggest delay was in the time from consent to implantation surgery, which has not improved despite the pandemic having ended.
