SACRAMENTO, Calif. — For the first time, California’s inspector general has declared that a state prison is providing above-average medical care to inmates.

A report released Friday found that the California City Correctional Facility is providing a “proficient” level of care to nearly 2,200 male inmates. That’s the highest of three possible grades.

Inspectors say California City has a system to make sure inmates receive care without delays, unlike some other prisons.

The state has leased the privately built prison 110 miles north of Los Angeles since 2013, but it is staffed with state employees. Most of the inmates are lower-security with relatively few chronic health problems.

Officials previously found that 17 state prisons are providing adequate care. Another 11 prisons still provide substandard care after 10 years of oversight to improve conditions.
