Why the study?
Parkinson disease is not currently included in Society of Thoracic Surgeons risk stratification models, leaving a need for large-scale contemporary data on cardiovascular surgery outcomes in this population.
Does comorbid Parkinson disease increase the risk of adverse outcomes and resource utilization in patients undergoing cardiovascular surgery?
Does comorbid Parkinson disease increase the risk of adverse outcomes and resource utilization in patients undergoing cardiovascular surgery?
Patients with Parkinson disease undergoing cardiovascular surgery have similar in-hospital survival to those without the condition, but face significantly higher rates of in-hospital complications, longer lengths of stay, and non-home discharges.
Anticipate higher resource use after CV surgery in Parkinson disease; leaves open causality and mitigation pending prospective studies.
Background: Notably, movement disorders like Parkinson disease (PD) are not currently included in the Society of Thoracic Surgeons risk stratification models. This study aimed to provide large-scale contemporary data describing cardiovascular surgery outcomes in patients with PD. Methods: Between 2016 and 2019, the Nationwide Inpatient Sample included 1,051,725 discharges for coronary artery bypass grafting (CABG), valve, aortic, or other cardiovascular surgery. Among these were 4675 patients (0.44%) with a diagnostic code for PD. Balancing-score matching and logistic regression were used to evaluate the influence of PD on cardiovascular surgery outcomes. Conclusions: Cardiovascular surgery can be performed safely on patients with PD with no increased hospital mortality, but these procedures are associated with more frequent complications, more frequent nonhome discharges, longer hospital length of stay, and higher costs. Surgeons may consider involving neurologic disorder experts to optimize the care of this vulnerable population.
