In its proposal to the Physician-Focused Payment Model Technical Advisory Committee of the CMS, the AAFP noted these key findings:
In a simulation model, a permanent 10% increase in Medicare fees for primary care ambulatory visits resulted in a six-fold annual return on investment in the form of lower Medicare costs for other services, primarily inpatient and post-acute care.
The Rhode Island insurance commissioner reported that a 23% increase in primary care spending between 2007 and 2011 was associated with an 18% reduction in total spending—a 15-fold return on investment.
Additionally, a 2016 Portland State University study found that every $1 increase in primary care expenditures in Oregon’s Patient-Centered Primary Care Home (PCPCH) program resulted in a $13 savings in specialty care, ED, inpatient care, and other healthcare services. Practice teams promoting six core attributes of primary care achieved $240 million in savings in the first three years of the program—$41 in savings per patient, per quarter.
