A CNA sits with a nursing home resident who's enjoying a cup of coffee.

Certified nursing assistants, or CNAs, are important members of a direct care nursing team. They’re commonly employed in long-term care facilities, hospices, home health, and hospitals. As caregivers, CNAs are responsible for reducing the risk of patient harm. The care they provide prevents adverse events, such as pressure ulcers and falls, that cost the healthcare industry billions of dollars a year.

A balanced workload helps reduce the risk of patient harm, while helping with retention, but in many states, there’s no limit to the number of patients a CNA cares for on a given shift. We’ve compiled the CNA patient ratio laws by state below. But first, some context about the work of a CNA and how care standards are quantified.

How Direct Care Nursing Teams Work

The most common workplaces for CNAs are post-acute care facilities, which include assisted living, skilled nursing facilities, and nursing homes. In these settings, nursing care is divided among disciplines. Licensed nursing professionals and aids provide hands-on care to residents. Direct care nursing staff consists of:

  • Registered nurses (RNs)
  • Licensed practical nurses (LPNs)
  • Certified nursing assistants (CNAs)

A healthcare administrator, such as a director of nursing (DON), oversees staff and residents. Because they round on residents and families throughout the day, the DON may count in nurse staffing hours.

Per nursing home regulations, residents’ time with nursing staff is measured in staffing hours per resident per day (HPRD). This metric is used to measure how much nursing attention a resident gets in a 24-hour period. Some states have guidelines for HPRD, whereas others have mandated CNA-to-patient ratios.

State Guidelines for CNA-to-Patient Ratios

If you’re looking to improve your facility’s patient safety standards and the positions you’ll need to fill, you may be wondering, “What is the legal CNA-to-patient ratio in a hospital?” The answer isn’t clear cut, as there’s wide variance in CNA patient ratio laws by state (and additional differences among types of facilities). For example, the CNA-to-patient ratio in North Carolina may be different than in Illinois, where facilities may face fines if they don’t meet staffing standards.

The federal government recommends residents in nursing homes receive 4.1 HPRD of direct nursing care per day. However, this isn’t mandated — it’s up to individual states to define safe staffing standards — but properly staffing your facility with the right balance of CNAs can go a long way toward improving CMS compliance, in addition to providing better care for residents.

This doesn’t let facilities off the hook, though. The Centers for Medicare and Medicaid Services (CMS) holds nursing homes accountable for their conditions with a public reporting and rating system. The Five Star Quality Rating System is designed to offer information to the public about nursing home staffing data, including:

  • Nurse staffing hours per resident per day
  • Nurse turnover
  • Administrator turnover

The report is released quarterly and is meant to encourage facilities to be transparent about staffing. Facilities must also submit an annual assessment that addresses residents’ needs and the facility’s ability to meet them. While CMS can’t enforce staffing ratios, it recommends facilities have “sufficient staff” to meet the needs of residents within a 24-hour period.

Public reporting is available on Medicare’s Care Compare site, which shows data about nurse staffing and time with residents.

Care Standards by State

States without staffing ratio mandates refer to CMS guidelines, which state the facility must have “sufficient staff” to care for all residents. This language leaves it up to facilities to define what appropriate staffing means for their residents. This is why it’s so important to understand the nuances of CNA patient ratio laws by state. Here are some questions to ask when considering what sufficient staffing means at your facility:

  • With these staffing ratios, will caregivers be able to uphold high-quality standards of care (such as skin breakdown prevention, fall prevention, etc.)?
  • Could these staffing ratios put a nurse’s license at risk?
  • Will residents’ families feel safe leaving a loved one in your facility?
  • Would you send a loved one to your own facility?

Other states have mandates to determine staffing standards, such as:

  • The number of direct care staff (RN, LPN, or CNA) per resident
  • CNA-to-patient ratios
  • Hours per resident per day (HPRD)

In certain states, such as Delaware and California, facilities may submit a waiver to bypass staffing minimums. Read about the CNA patient ratio laws by state for more details.
