Nurse turnover is the rate at which nurses leave their positions over a set period, whether they quit, transfer to a different unit, or are let go. In 2024, the national registered nurse turnover rate was 16.4%, and the cost of replacing a single bedside RN averages about $40,000. It’s one of the most persistent problems in healthcare, affecting hospital budgets, staff morale, and patient safety in measurable ways.
Types of Nurse Turnover
Not all turnover looks the same. The two broadest categories are internal and external. Internal turnover means a nurse changes positions within the same organization, moving from one unit or role to another. External turnover means they leave the employer entirely, either for a different hospital, a non-clinical role, or retirement. Internal turnover can still disrupt a unit’s staffing and team dynamics, but external turnover is what drives the most significant costs, since the organization loses the nurse altogether and must recruit, hire, and train a replacement.
Turnover is also split into voluntary and involuntary. Voluntary turnover, by far the larger share, happens when nurses choose to leave. Involuntary turnover covers firings, layoffs, or contract non-renewals. The distinction matters because the strategies for reducing each type are completely different. Voluntary departures point to workplace problems an organization can fix. Involuntary ones are usually individual performance issues or budget decisions.
How Turnover Varies by Specialty
Some hospital units lose nurses far faster than others. Behavioral health has the highest turnover at 22.8%, followed by step-down units at 20.3% and emergency departments at 19.1%. Critical care and medical/surgical units hover around 18%. On the lower end, pediatrics (12.2%) and women’s health (13.3%) tend to retain nurses more effectively.
The cumulative toll is striking. Over the past five years, three specialties have seen cumulative turnover exceed 100%: step-down (120.8%), telemetry (117.6%), and emergency services (112.9%). That means these departments have effectively replaced their entire nursing staff in under four and a half years. The constant churn makes it difficult to build experienced teams, and the remaining nurses absorb extra workload each time a colleague leaves, which feeds a cycle of burnout and further departures.
Why Nurses Leave
The single biggest driver is burnout caused by patient overload. When a nurse is responsible for too many patients in a shift, they can’t deliver all the care those patients need or catch complications early enough. A landmark Penn Nursing study found that each additional patient assigned per nurse was associated with a 23% increase in the odds of burnout and a 15% increase in job dissatisfaction. Those aren’t small margins. A nurse carrying six patients instead of four faces compounding stress that builds shift after shift.
Trust in leadership is the other major factor. In survey data from hospital nurses across two states, over 69% said they lacked confidence that management would resolve clinical care problems nurses reported. During the pandemic, that figure rose to 78%. Nearly half of nurses before the pandemic felt that management’s actions showed patient safety wasn’t a top priority, and that concern grew to 58% during the pandemic. When nurses feel their concerns are ignored, especially about patient safety, they start looking for jobs elsewhere.
New graduates are especially vulnerable. About 24% of nurses leave the profession before completing their first year. The transition from school to practice is steep, and without structured support, many new nurses feel overwhelmed and underprepared for the realities of bedside care.
How Turnover Affects Patients
Nurse turnover isn’t just an HR problem. It has direct, measurable effects on patient outcomes. Research from the Upjohn Institute found that a 10 percentage point increase in nursing turnover resulted in a 9.4% to 17.4% increase in discharge death rates in nursing homes. Facility-acquired bedsores increased by 6.1% to 26.5% relative to baseline. The same study found that higher turnover led to increased use of catheters, which raise the risk of urinary tract infections, and physical restraints, both markers of lower-quality care.
Regulatory surveys reflect the damage too. A 10 percentage point increase in nurse turnover was associated with 2.2 additional deficiency citations per annual survey, a 19.3% increase. These deficiencies represent real failures in care standards that inspectors identify during facility reviews.
The mechanism is straightforward. Experienced nurses know their patients, recognize subtle changes in condition, and understand the routines of their unit. When turnover is high, units are staffed with newer nurses who are still learning, supplemented by temporary or traveling nurses who don’t know the facility’s workflows. That gap in institutional knowledge leads to missed warning signs and delayed interventions. Each additional patient per nurse is also linked to a 7% increase in the likelihood of a patient dying within 30 days of admission and a 7% increase in failure-to-rescue, the failure to catch and respond to post-surgical complications before they become fatal.
The Financial Cost
Replacing a bedside registered nurse costs between $28,400 and $51,700, with the average landing around $40,038. That figure covers recruitment, onboarding, training, and the lost productivity during the months it takes a new hire to reach full competency. For a mid-sized hospital that loses 50 nurses in a year, the tab can exceed $2 million before accounting for the overtime and travel nurse contracts needed to cover the gaps.
These costs compound in specialties with the highest turnover. An emergency department that replaces its entire staff every four years is spending continuously on recruitment and orientation, money that could otherwise go toward equipment, staffing improvements, or better compensation for the nurses who stay.
What Reduces Turnover
The strongest evidence supports nurse residency programs for new graduates. These structured programs typically include a reduced patient load during the transition period, classroom education, and an assigned mentor or preceptor. The two most widely adopted models, developed by the University Health Consortium/AACN and Versant, both report 93% retention rates among new nurse residents. In facilities that tracked turnover before and after implementing residency programs, first-year turnover dropped from 50% to 10% in one study and from 17% to 7.1% in another. Those are dramatic reductions that pay for themselves quickly given the cost of each departure.
Beyond residency programs, the research consistently points to staffing ratios as the lever with the most impact. Reducing the number of patients per nurse directly lowers burnout and dissatisfaction, the two strongest predictors of voluntary turnover. Leadership engagement matters as well. Programs succeed when chief nursing officers actively champion them and when organizations appoint dedicated coordinators to manage the residency experience.
The Bigger Picture
Federal projections estimate a shortage of roughly 109,000 registered nurses and 246,000 licensed practical nurses by 2038. Rural areas will be hit hardest, with an 11% projected RN shortage in nonmetropolitan areas compared to just 2% in metropolitan areas. Every nurse who leaves the profession, rather than simply changing employers, deepens that gap. High turnover isn’t just cycling nurses between hospitals. It’s pushing experienced clinicians out of bedside care entirely, and the pipeline of new graduates isn’t large enough to compensate when nearly a quarter leave within their first year.
The combination of an aging population needing more care and a workforce that’s burning out faster than it’s being replaced makes nurse turnover one of the defining challenges in American healthcare for the next two decades.
