- MISSION Act’s Double-Edged Sword: Improved Access, Worsened Outcomes for Veterans Undergoing Cardiac Procedures
The implementation of the MISSION Act, designed to enhance healthcare access for veterans by allowing them to seek care outside the Veterans Affairs (VA) system, has yielded mixed results. While the policy has demonstrably reduced travel times for veterans who become geographically eligible for non-VA care, a recent analysis reveals a concerning trend: for those undergoing Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Grafting (CABG), the MISSION Act’s rollout was associated with an increase in 30-day Major Adverse Cardiovascular Events (MACE) rates.
The Promise of Access vs. The Reality of Outcomes
The core objective of the MISSION Act was to improve veterans’ access to healthcare, notably for those living further from VA facilities. This aspect of the policy appears to have been triumphant, with veterans experiencing shorter travel times to receive care. Though, this increased convenience has come at a cost for a specific patient population.
PCI and CABG: A Troubling Correlation
for veterans undergoing PCI and CABG, the shift towards non-VA care, facilitated by the MISSION Act, coincided with a statistically important worsening of 30-day MACE rates. This finding suggests that while access may have improved, the quality or effectiveness of care for these complex procedures may have been compromised when delivered outside the customary VA system.
Expert Commentary: The Importance of System and Team Expertise
The observed outcomes are not entirely surprising to some in the medical community. As one commentator noted, while procedures like atrial Fibrillation (AF) ablation are widely practiced and can be effectively performed in many major cities, complex interventions such as PCI, CABG, and Aortic Valve Replacement (AVR) demand more than just a skilled physician. They require a highly coordinated and experienced team, supported by robust institutional processes.
VA Hospitals: Strengths in Process and Dedication
Commentary highlights that VA hospitals, despite potential shortcomings in amenities, often excel in their operational processes and the dedication of their staff.This is supported by existing research, with several observational studies cited in the introduction of the analyzed paper indicating that VA cardiac catheterization labs have demonstrated better mortality rates compared to non-VA cath labs. this suggests a potential advantage in the standardized, team-based approach often found within the VA system for these critical procedures.
the “Wild West” of Healthcare Variability
The disparity in outcomes can be attributed to the significant variability in healthcare quality across the United States. While VA care is characterized by standardization, the broader US healthcare landscape, particularly in areas outside major medical centers, can be more unpredictable. This “Wild West” scenario means that while veterans might find care closer to home, the expertise and consistency of the teams performing complex cardiac procedures may vary considerably. This is analogous to healthcare systems in other countries, such as Canada, where specialized procedures are often concentrated in fewer centers, ensuring that physicians and teams gain extensive experience through high patient volumes.
Policy Lessons: The Need for Pilot Programs and evidence-Based Implementation
The findings from the MISSION Act’s implementation offer critical lessons for healthcare policy.
The Peril of Untested Policies
The commentator emphasizes the potential pitfalls of implementing large-scale policies without prior rigorous testing. The assumption that increased convenience automatically translates to better outcomes, especially for complex medical interventions, proved to be flawed. The policy’s focus on improving access, while laudable, overlooked the critical importance of maintaining the quality and consistency of care for high-risk procedures.
The Case for Randomized Controlled Trials (RCTs) in Policy
A strong argument is made for the necessity of piloting policy changes through rcts, similar to how new drugs and medical devices are evaluated.Policies, by their nature, can impact vast numbers of people, and their potential for unintended consequences, as seen with the MISSION Act’s impact on cardiac outcomes, underscores the need for evidence-based implementation. Just as clinical trials are essential to ensure the safety and efficacy of medical interventions, pilot programs and RCTs are crucial for validating the effectiveness and mitigating the risks of healthcare policies before widespread adoption. This proactive approach allows for mid-course corrections, preventing potential harm and ensuring that policy changes truly benefit the intended population.
