California’s new emergency nurse-to-patient staffing ratios for acute psychiatric hospitals took effect June 1, closing a regulatory gap that had left freestanding psychiatric facilities without mandated minimums for more than two decades. But leaders are raising concerns about behavioral healthcare access and workforce turnover.
Here are six things health system and hospital leaders should know about the staffing rules:
1. What are the California emergency psychiatric staffing rules?
The emergency regulations require psychiatric hospitals to staff at least one licensed nurse for every six adult patients and at least one licensed nurse for every five patients younger than 18.
Licensed vocational nurses, psychiatric technicians or a combination of both should not exceed 50% of the licensed nurses on the unit. Any licensed nurse included in the nurse-to-patient ratio should be awake and on duty in the hospital.
2. When did the state implement the nursing ratios?
In 1999, Gov. Gray Davis signed a bill that directed the state to set fixed nurse-to-patient ratios for general acute care hospitals, acute psychiatric hospitals and specialty hospitals.
Final regulations were issued in the summer of 2003, and hospitals were required to comply by Jan. 1, 2004. However, those regulations covered only psychiatric units inside general acute care hospitals and state-run psychiatric hospitals. Freestanding acute psychiatric hospitals not operated by the state were left out, a gap that persisted for more than two decades.
That gap closed after a 2025 state budget bill directed the California Department of Public Health to adopt emergency regulations specifically for acute psychiatric hospitals by Jan. 31, 2026. The agency delayed that deadline to June 1, 2026, following pushback from hospitals and the public, and the new ratios took effect on that date.
The current rules remain emergency regulations, and CDPH has until July 31, 2027, to finalize permanent rules.
3. Why were the emergency staffing rules implemented?
The staffing requirements were prompted by an investigative series into widespread dysfunction, abuse and understaffing at California behavioral health hospitals published by the San Francisco Chronicle.
4. How are psychiatric hospitals being affected?
Hospital leaders warned the staffing requirements could further strain access to psychiatric care in a state already facing bed shortages and workforce challenges. California has about 7,000 psychiatric inpatient beds — roughly 2,000 short of demand. In 24 of the state’s 58 counties, residents do not have access to acute psychiatric beds. For adolescents, access is available in only 15 counties.
According to a June 9 California Hospital Association statement, the counties that closed beds were Kern, Contra Costa, Madera and San Diego, with each losing an average of 15% of their acute psychiatric beds. Contra Costa was hit hardest, losing 29%.
Walnut Creek, Calif.-based John Muir Health was forced to temporarily close 21 psychiatric beds, effective June 1, including a 10-bed child psychiatric unit serving patients younger than 12 and an 11-bed adult psychiatric unit — a direct result of California’s emergency nurse-to-patient staffing ratio order.
The system holds roughly 10% to 15% of all inpatient psychiatric capacity in the state for children younger than 12, making the closures especially significant.
The California Department of Public Health recently approved temporary rule waivers for 23 hospitals, including John Muir.
Experienced behavioral health staff have also taken a hit.
To meet the ratios, many hospitals are letting go of experienced behavioral health technicians and mental health counselors, positions not included under the regulations. These workers, many with years or decades of experience, are being replaced by freshly hired nurses, in many cases recent graduates with no psychiatric training.
In the first weeks of the new regulations, hospitals have reported dozens of nurse resignations, including newly hired staff who struggle with the tough realities of psychiatric care. On the other side of the spectrum, some experienced RNs who have worked in these hospitals for years are now being asked to do work that falls below their licensure level.
5. How much does this cost?
The implementation of ratios were estimated to cost more than $145.2 million statewide, including $107.7 million for salaries and benefits and $37.5 million for recruitment, training and onboarding costs.
Hospitals that fail to meet the ratios are required to reduce patient capacity. Violations would carry fines of $15,000 for the first violation and $30,000 for the second and each subsequent violation.
6. What are the ripple effects?
It remains unclear whether California’s psychiatric nursing pipeline can sustain this workforce shift over time, and how this is affecting nurses across the state as they enter into psychiatric care as fresh graduates.
About half of the state’s acute psychiatric hospitals are in counties identified as a Registered Nurse Shortage Area and/or Licensed Vocational Nurse Shortage Area, according to the California Department of Health Care Access and Information. The 2025 NSI National Health Care Retention & RN Staffing Report found registered nurse turnover averages 16.4% nationally, with more than 1 in 5 newly hired RNs leaving within their first year.
Nursing leaders have also found a widening gap between what a nursing degree certifies and what a hospital unit demands in practice.
Although hospitals have struggled to implement the new staffing ratios, National Nurses United has supported the changes. The union represents more than 100,000 nurses across California.
RNs represented by the California Nurses Association celebrated the “long-awaited safe” nurse-to-staff ratios, stating they should “dramatically improve the care behavioral health patients receive” and “save lives.”
