A new survey from The Kaiser Family Foundation and The Commonwealth Fund asked primary care providers—physicians, nurse practitioners, and physician assistants—about their views of and experiences with the Affordable Care Act (ACA) and other changes in health care delivery and payment, as well as their thoughts on the future of primary care. In this first brief based on the survey, many providers reported seeing an increased number of patients since the coverage expansions went into effect, but not an accompanying compromise in quality of care. A large majority of primary care providers are satisfied with their medical practice, but a substantial percentage of physicians expressed pessimism about the future of primary care. Similar to the population overall, providers' views of the ACA are divided along party lines. A second brief will report on providers' reactions to other changes occurring in primary care delivery and payment.
