2014 News

Craig Paxton, of Cattaneo & Stroud, authored the California Healthcare Foundation (CHCF) 2014 Physician Almanac: California Physicians: Surplus or Scarcity?

The number of physicians in California increased 39% from 1993 to 2011, and has outpaced the state’s 20% growth rate in the general population. Demand for physician services is expected to increase with the aging of the state’s population and the implementation of the Affordable Care Act. Ensuring access to care is also a concern, as close to one-third of California’s physicians are near retirement age.

California Physicians: Surplus or Scarcity? describes the current market landscape for physician services in California.

Key findings include:

  • Physician supply varies by region, with both Inland Empire and San Joaquin Valley significantly below the recommended levels
  • 20% of California physicians devote fewer than 20 hours a week to patient care.
    Slightly more than 30% of California physicians were over the age of 60 — only New Mexico has an older population of physicians.
  • While 38% of the state’s population is Latino, only 4% of physicians are.
    More than three-quarters of California physicians attended medical school in other states or in foreign countries.
