Some say California's doctor shortage is a pipeline problem — build more medical schools, mint more graduates. But a 2025 study in the Annals of Internal Medicine tracked 712,000 physicians and found clinical attrition jumped 40 percent between 2013 and 2019. The cause: prior authorization paperwork, insurance bureaucracy, and understaffing. Pipeline gaps didn't even register.

Here's the boardroom angle Sacramento keeps ducking: a 2024 Health Affairs study found private equity-owned physician practice sites grew from 816 in 2012 to 5,779 by 2021, with a single PE firm holding majority market share in 50 specialty-and-metro markets. After acquisition, physician turnover jumped 13 percentage points — a 265 percent increase. California Governor Newsom vetoed AB 3129, the bill that would have brought attorney-general scrutiny to those deals.

Said Dr. Frances Mei Hardin, an ENT surgeon who left clinical medicine last year: "Build all the medical schools you want. The graduates will keep walking out the back door." The patients left holding the bill are farmworkers in Tulare and working families in San Bernardino who can't drive three hours to see a specialist.
