Ownership conversions between nonprofit and for-profit statuses impact operational priorities and care quality. The changes in reimbursement policies have significantly influenced these organizations, enhancing care quality and financial stability. Recent transparency measures and charity care requirements further ensure accountability. The findings underscore the vital role of nonprofit healthcare providers in delivering high-quality, accessible care and inform future research considerations.
