Healthcare Staffing Metrics Every Facility Should Track

Low HCAHPS scores, medication errors, and high turnover.

Any of these metrics points to a common, but often overlooked, culprit: inefficient healthcare staffing.

When healthcare facilities are understaffed, clinicians are overworked, and staffing solutions are reactive rather than proactive, organizations experience a domino effect of negative consequences that impact patient care, staff well-being, and facility budgets.

Don’t wait for the negative outcomes. Hospitals and clinics must continuously track healthcare staffing metrics to address concerns early on.

Stop putting out fires. Get your staffing metrics back in the green.

In this article, we’ll explore the top staffing metrics each facility should track, provide benchmarks, and help you understand what red flags to watch.

Assess these patient care and safety metrics

Wondering how to measure healthcare staffing effectiveness?

Facilities must consider a range of metrics from patient-to-staff ratios to hospital-acquired infection rates and patient satisfaction scores. These not only help healthcare leaders understand important information about overall patient safety, but also serve as indicators of deeper issues.

Patient-to-staff ratio

Appropriate patient-to-staff ratios should be non-negotiable.

Regardless of changes in federal mandates or specific state nurse-to-patient ratios, healthcare facilities should be proactive in maintaining safe staffing ratios.

The nurse staffing shortage, leaves of absence, and last-minute call outs are not excuses. Facilities must foresee all these situations, plan for them, and have several staffing solutions available when these needs arise.

Why?

If this metric is not protected, all other patient care and safety metrics are affected.

What is a reasonable nurse-to-patient ratio benchmark?

Reasonable nurse-to-patient staffing ratios vary significantly across healthcare settings. Recommended or mandated benchmarks depend on unit type, acuity level, and patient age, among other factors.

For instance, intensive care units (ICUs) typically require 1 registered nurse (RN) for every 1–2 patients, providing care 12–24 hours per day. However, in a nursing home, 2–4 hours of direct care per resident day is generally adequate.

Medication error rate

“The Influence of Nurses’ Characteristics on Medication Administration Errors: An Integrative Review” offers a broad overview of the prevalence of medication errors in healthcare settings and the factors that are associated with those errors:

Medication errors, especially medication administration errors, are a frequent cause of morbidity and mortality, causing between 44,000 and 98,000 deaths per year in the United States.
Medication administration errors are among the most common medical errors to occur in acute care settings and can result in prolonged hospital stays.
Although system errors contribute to medication errors, a significant number occur during medication administration, which is typically the responsibility of nurses.
Nurse staffing levels and heavy workloads have been strongly associated with medication errors in acute care settings.
Psychological factors among nurses, such as burnout and compassion fatigue, have also been associated with medication errors.

In short, a high or increasing rate of medication errors is an indicator of inefficient nursing staff performance, which may, in turn, be caused by understaffing.

Hospital-acquired infection rate

“On any given day, 1 in 31 hospital patients and 1 in 43 nursing home residents has an HAI. About half of hospital patients and 1 in 12 nursing home residents receive an antimicrobial medication.”
– HAI and Antimicrobial Use Prevalence Surveys

A recent study titled “Nurse Staffing and Hospital-Acquired Infections in Rural Versus Non-Rural Hospitals” highlights the importance of addressing hospital-acquired infections (HAIs), both for patient safety and financial considerations.

HAIs lead to approximately 98,000 deaths in the United States.
They also add billions of dollars to healthcare costs each year, an estimated $31,000 per case.
Costs associated with HAIs are not reimbursed by Medicare or Medicaid. Furthermore, the Centers for Medicare & Medicaid Services (CMS) Hospital-Acquired Condition (HAC) Reduction Program reduces payments to hospitals based on their performance regarding HAIs.

A key finding from a study titled “Closing the Gap on Infection Prevention Staffing Recommendations: Results from the Beta Version of the APIC Staffing Calculator” was the correlation between staffing levels and infection outcomes. The study found that programs with staffing levels below expectations were more likely to have higher standardized infection ratios (SIRs).

Patient satisfaction scores

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey asks discharged patients 32 questions about their recent hospital stays, including:

Communication with nurses and doctors
Responsiveness of hospital staff
Cleanliness and the hospital environment
Communication about medicines
Discharge information
Care coordination
Information about symptoms

It is evident that HCAHPS scores are largely dependent on the state of the nursing workforce:

Overall staffing levels
Percentage of experienced staff vs. new nurses
Percentage of long-term staff vs. temporary nurses
Levels of staff burnout and overall job satisfaction

Analyze healthcare workforce stability and retention metrics

The following metrics are essential to guide effective healthcare workforce planning.

Nurse turnover rate

Nurse turnover has far-reaching impacts on a healthcare facility.

Open shifts must be filled.
Continuity of care may be compromised.
Potential candidates must be evaluated and offers made, with all the resume reviews and interviews that work implies.
Recruits must be onboarded and trained, occupying valuable resources.

In short, it is no simple task to replace staff. Therefore, facilities should assess and strive to reduce their nurse turnover rate.

How do I calculate nurse turnover rate?

Healthcare facilities can calculate turnover on a monthly, quarterly, or annual basis. Organizations can also track the turnover rate within specific groups, such as new hires or units.

In any of these cases, simply divide the total number of separations during the period by the average headcount during that same period and multiply by 100.

Turnover rate = (# of separations / average headcount) x 100

Voluntary vs. involuntary separation rate

Nurse turnover is a complex issue that may be caused by various factors and may be voluntary or involuntary for clinicians.

A case study carried out at Cincinnati Children’s Hospital serves as an example of how healthcare facilities can significantly reduce voluntary separation:

By implementing retention strategies informed by exit interviews, the hospital reduced employee turnover by up to 70% in some areas.
The reasons for leaving shifted from hospital- and supervisor-driven concerns to personal, non-hospital-driven issues.
Retention and engagement were most effectively impacted when actions were taken at the departmental or business-unit level.

In the context of continuing nurse staffing shortages, reducing voluntary separation metrics should be a top priority for healthcare facilities. As the case study found, reasons for turnover may be varied and should be addressed at the unit level. However, common reasons include:

Stress
Job dissatisfaction
Managerial style
Supervisory support
Work schedules

Retention rate (by unit and by shift)

Another important metric to understand and address workforce stability is the retention rate by unit and shift.

A study titled “Newly Licensed RN Retention: Hospital and Nurse Characteristics” found the following retention rates per shift type:

Rotating shifts: 83%
Day shifts: 84%
Evening shifts: 88%
Night shifts: 89%

Interestingly, the shift type that has the worst retention rate is the rotating shift, indicating nurses’ desire for predictability and control over their schedules. Another interesting finding is that night shifts had the highest retention rate in this study. This may reflect the impact of night shift differentials on retention.

This particular study found no differences in retention by unit type. However, a 2025 article published by Becker’s Clinical Leadership indicated the following turnover rates by nursing specialty:

Behavioral health: 22.8%
Step-down: 20.3%
Emergency: 19.1%
Critical care: 18.3%
Medical-surgical: 18%
Telemetry: 17.4%
Burn center: 17%
Surgical services: 13.7 %
Women’s health: 13.3%
Pediatrics: 12.2%

These statistics offer a snapshot of potential problem areas for healthcare administrators and indicate where retention efforts could be concentrated. However, each facility is different, and retention rates and strategies should be considered individually.

Staff satisfaction scores

Don’t wait for the exit interview.

Staff satisfaction metrics enable healthcare facilities to proactively reduce turnover rates. The following are the areas healthcare workers consider most important based on a 2025 study titled “Charting Employee Satisfaction in U.S. Hospitals: Insights into Job Fulfillment, Stressors, and Involvement.”

Leadership: Effective leadership is the most mentioned factor related to high employee satisfaction. It is essential for a supportive and empowering work environment; it contributes to open communication and provides clear direction and purpose.
Workplace culture: Various studies have found that employees who perceive their workplace culture as inclusive and supportive are more committed to their organizations and express lower intention to leave.
Career growth: For healthcare workers, clear career paths and opportunities for professional development contribute to higher job satisfaction, motivation, and loyalty to the organization.
Financial compensation: Competitive pay is necessary for job satisfaction, but not enough on its own to retain staff long term. Employees also need to feel valued and supported in other ways.
Additional perks: Benefits, such as bonuses, health benefits, and other incentives, enhance job satisfaction by providing employees with a sense of security and appreciation.
Work-life balance: Flexible schedules and remote work opportunities contribute positively to employee satisfaction. Workers who can balance their work and personal lives are more likely to experience higher job satisfaction and lower stress.

Review operational efficiency metrics

How often should administrators review operational efficiency staffing data?

The short answer is constantly. A single unfilled shift can have long-lasting effects.

Shift fill rate

The shift fill rate is the percentage of required shifts that are filled in a given period.

What is a healthy shift fill rate?

The truth is that any shift fill rate below 100% is problematic; it indicates shifts went unfilled, potentially placing patients at risk. A declining trend in a facility’s shift fill rate indicates a need for both short-term staffing solutions and long-term recruitment.

Short-term solutions, such as internal float pools, nurse staffing agencies, and digital platforms, allow facilities to cover last-minute needs and maintain safe staffing ratios and manageable workloads.
Long-term recruitment efforts ensure a solid core of in-house staff who are familiar with facility procedures and policies. A majority of in-house staff is also important for effective teamwork and continuity of care.

Time-to-fill open healthcare positions

In addition to measuring their shift fill rates, facilities should assess how quickly they can fill open shifts. If it takes several days or even weeks to cover the schedule gaps left by employees on leave, facilities must find more effective solutions for on-demand staffing needs.

Agency-to-permanent staff ratio

There is no doubt that staffing agencies play an important role in maintaining healthcare operations. However, overreliance can significantly strain budgets.

Data from Premier, a healthcare improvement company, indicates that average hospital hourly wage rates have increased 34% since 2019, whereas agency rates have increased 63%.

Tracking agency-to-permanent staff ratios can help chief nursing officers and chief financial officers determine whether it would be in their facilities’ best interests to invest in long-term recruitment in order to reduce agency staffing.

Float pool utilization rate

How does float pool utilization affect staffing costs?

Facilities that rely heavily on nurse staffing agencies should consider expanding their internal float pool to reduce agency spending and overtime rates.

Internal float pool staff are also more familiar with facility policies and procedures and are more likely to have worked with a given unit’s core staff in the past.

PRN and supplemental staff utilization ratio

Facilities should ensure that their core internal staff can cover most of their staffing needs. However, supplemental staff will still be needed in various situations.

Patient census surges
Planned employee leaves of absence
Staff turnover
Last-minute call outs

Although in an ideal scenario, facilities would be able to cover all their staffing needs with internal staff, they must also plan for the inevitable supplemental staffing needs. Relying—to a certain extent—on external PRN staff allows facilities to reduce overtime and protect internal staff from burnout.

Track these financial metrics to protect your budget

What are the most important staffing metrics for healthcare facilities to track from a financial standpoint?

Identify preventable expenses and take control of your budget.

Overtime rate and percentage of your labor budget

Staff overtime rates strain facilities’ already-tight budgets. Healthcare facilities must pay employees time and a half for hours worked beyond their regular schedules.

Healthcare administrators should also consider the long-term financial impacts of mandatory overtime on staff turnover.

As with reliance on supplemental staff, facilities should assess the percentage of their budgets being dedicated to paying overtime rates to determine whether resources would be better spent hiring additional employees.

Cost per hire and impact of turnover in healthcare

The “2025 NSI National Health Care Retention & RN Staffing Report” places the average cost of replacing a bedside RN at $61,110. Based on report estimates, the average hospital could save $289,000 per year by reducing turnover by just 1%.

A 2026 study titled “Operationalizing the RETAIN Framework: Calculating the Cost of Nurse Turnover in Practice” found the following estimates grounded in actual financial records:

The turnover rate in a cohort of 1,501 medical-surgical nurses across 7 hospitals reached 24%.
These vacancies took an average of 21.7 weeks to fill, and 75.5% were covered by high-cost contract labor.
When a contract nurse filled a vacancy, turnover costs rose to $85,498 per nurse.
The total annual system cost was $27.9 million.
Sensitivity analyses indicated that reducing turnover and reliance on contract nurses could save more than $20 million.

Financial leaders must understand that nurse retention strategies offer a significant return on investment.

Aside from quantifiable costs, turnover implies huge time investments in onboarding and training new staff, which impacts productivity and disrupts patient care.

Cost per patient day

Data from the Kaiser Family Foundation indicates that the average cost of an inpatient hospital stay per day is $3,297.

Ironically, hospitals that are understaffed—theoretically saving money on labor—may lose millions of dollars in unnecessary patient stays. Therefore, ensuring adequate staffing—using a combination of long-term and supplemental staff—can actually save a facility money.

Prioritize these compliance and credentialing metrics

Which staffing metrics are most important for regulatory compliance?

Credential compliance rate

In 2023, the U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG) and law enforcement partners launched a multi-state coordinated law enforcement action to arrest individuals selling false and fraudulent nursing degree diplomas and transcripts, resulting in the apprehension of 25 people.

Credential verification is not simply an administrative task to cross off a to-do list. Credential compliance is non-negotiable for ensuring patient safety—not to mention protecting facilities from liability.

Time-to-credential new hires

Before new nurse hires can begin providing care, healthcare facilities must ensure compliance with various requirements:

Holding a valid, active license in the state
Passing background checks for criminal, drug abuse, or sexual harassment history
Meeting federal and state labor laws regarding employment and workplace policies
Completing training on safety standards during the onboarding process, including Occupational Safety and Health Administration (OSHA) and Health Insurance Portability and Accountability Act (HIPAA) trainings

The longer the time to credential, the longer shifts stay unfilled, compromising patient care.

Mandatory training completion rate

Your facility’s mandatory training completion rate is the percentage of employees who have completed the required training out of the total number of employees required to complete it.

A high rate suggests that employees are well-prepared and compliant with training mandates. A low completion rate indicates various potential issues:

Lack of employee engagement
Inadequate training programs
Insufficient monitoring and follow-up

Low mandatory training completion rates can leave employees lacking the necessary skills and knowledge, potentially impacting their performance and compliance.

What should I do when my staffing data indicates a shortage?

When any staffing key performance indicators (KPIs) are concerning, healthcare facilities must take action.

First step: Fill open shifts

Is the hospital-acquired infection rate in your facility high?
Are staff satisfaction scores low?
Are you struggling with nurse turnover?

Any of these issues could indicate inadequate staffing levels.

Ensure you have effective staffing solutions at your disposal, ready to be deployed at a moment's notice. Using tech-enabled platforms, such as Nursa, streamlines on-demand access to qualified, credentialed nurses when any of these metrics turn red, and your facility needs immediate coverage.

Address the root cause of staffing issues

Over the next 30 to 90 days, you can make significant headway in turning around problematic metrics.

Expand your internal float pool if you have been relying too heavily on agencies.
Initiate retention initiatives based on staff satisfaction scores and feedback from nurse leader rounding.
Use PRN clinicians to help ensure scheduling equity for internal staff and protect your core team from burnout.

Stop reacting: Plan for staffing needs proactively

Track and analyze trend data to forecast staffing needs 60 to 90 days out, rather than filling gaps after they've already opened. Planning ahead gives you more options, control, and flexibility.

Is an employee scheduled to go on maternity leave within the next 3 months?

A travel nursing contract may be the best solution to cover the schedule gap.

Is an employee nearing retirement?

Don’t wait for the 2-week notice. Begin your recruitment process now.

The bottom line

When your facility is understaffed, you need to fill the gaps. Period.

Analyze which staffing solution best meets your needs for each situation.

Nursa helps healthcare facilities cover last-minute staffing needs by connecting them directly with qualified, credentialed nurses on demand.

Healthcare facilities can sign up for free and post PRN shifts as needed to maintain healthcare staffing metrics in the green.
