a Adapted from the American Medical Association (2001-2015).

In 2013, there were 209,927 primary care providers in the United States.

This translates to ~1 primary care provider per 140 adult U.S. residents with CKD stages 1-4.
Chart Explanation: In 2013, there were 209,927 primary care providers in the United States. The numbers of primary care providers has increased by ~29,000 (~14% increase) since 1999. The percentage listing general practice as their specialty has declined over this period, while the percentage listing family medicine or internal medicine as their specialty has increased. There were approximately 140 adult (>=20 years) CKD patients per U.S. primary care provider in 2013, using NHANES estimates.
The American Medical Association (AMA) tracks data on all physicians in the United States, starting in medical school. Current demographic, training, practice and specialty data are available through the AMA Physician Masterfile. The Physician Characteristics volumes (AMA, 2001-2013) produce yearly counts of physicians by specialty, and counts of physicians listed as “providing medical care” (versus research, teaching, or administrative tasks) were counted here; resident/fellow/staff and office- and hospital-based physicians were included.

Limitations of IndicatorPhysicians may not keep information current; not all physicians are members of AMA and thus may be harder to track over time; specialty is self-reported and may not reflect patient care
Analytic ConsiderationsCKD/ESRD prevalence data can be used for population denominator (per patient); only those listed as providing patient care should be included
