Why Your PRN Strategy Is Failing Your Long-Term Retention
Retention problems that PRN alone can’t fix
Hospitals and post-acute facilities are pouring money into PRN and contract coverage, yet nurse turnover and burnout remain stubbornly high. Recent national retention reports estimate the average cost of turnover for one staff RN at roughly $50,000–$60,000, with the average hospital losing millions of dollars per year due to RN turnover alone. (NSI National Health Care Retention & RN Staffing Report)
High turnover also drives additional workload for remaining staff, creating a cycle of burnout, dissatisfaction, and further exits. (International Journal of Nursing Studies – Worldwide Prevalence and Associated Factors of Nursing Staff Turnover)
Many leaders respond by adding more PRN shifts and short-term contracts, assuming that filling the schedule is the same as stabilizing the workforce. In reality, a PRN-heavy model without a retention strategy can accelerate turnover by normalizing chronic vacancies and overburdening core staff. (Journal of Healthcare Management – The Race to Retain Nursing Workforce in Healthcare)
The vicious cycle: PRN, overtime, and burnout
When core positions are left vacant, remaining nurses often work extra hours, rotate into unfamiliar units, or pick up overtime just to keep the unit afloat. A large hospital-based study found that nurses working 12 hour shifts or longer had significantly higher odds of high burnout, job dissatisfaction, and intention to leave compared with nurses working 8 hour shifts or less.
(BMJ Open – Association of 12 h Shifts and Nurses’ Job Satisfaction, Burnout and Intention to Leave)
Burnout is not just an emotional issue; it is a proven retention driver. A national analysis of U.S. nurses reported that about one third of nurses who left their most recent job cited burnout as a key reason for leaving. (JAMA Network Open – Prevalence of and Factors Associated With Nurse Burnout in the US)
When organizations repeatedly rely on PRN and overtime instead of addressing root causes—such as staffing levels, leadership support, and workload design—burnout becomes embedded in the system. (JAMA Network Open – Prevalence of and Factors Associated With Nurse Burnout in the US; International Journal of Nursing Studies – Worldwide Prevalence and Associated Factors of Nursing Staff Turnover)
What most organizations get wrong about PRN staffing
Most organizations fall into three common traps.
1. Treating PRN as the strategy, not a tool
PRN pools, local per diem, and travelers are essential, but they were never designed to replace a stable core workforce. Empirical research has shown that high turnover and inadequate staffing are associated with poorer quality, more adverse events, and lower patient satisfaction. (Journal of Operations Management – The Impact of Nurse Staffing on Turnover and Quality)
If PRN usage simply grows in proportion to vacancies, the organization is managing scarcity, not building stability.
2. Ignoring the leadership–retention connection
Multiple studies demonstrate that leadership style and the work environment have a significant impact on nurse retention and intent to stay. An integrative review concluded that transformational leadership is consistently associated with better nurse retention, higher job satisfaction, and healthier work environments. (Nursing Reports – Transformational Leadership and Nursing Retention: An Integrative Review)
Other work has found strong relationships between supportive leadership, job satisfaction, and nurse retention in clinical settings. (International Journal of Research and Scientific Innovation – Leadership Style and Job Satisfaction on Retention Among Nurses; Lex Localis – Influence of Nursing Leadership on Staff Retention)
When leadership gaps exist—weak support, poor communication, inconsistent accountability—no amount of PRN coverage will rebuild trust or engagement.
3. Using PRN to mask structural issues
PRN is often deployed to cover underlying problems: unsafe ratios, inefficient workflows, or chronic underinvestment in certain units. Evidence indicates that frequent staff turnover and inadequate staffing weaken continuity of care and can worsen quality and safety outcomes, especially in high-acuity and long-term care settings. (Health Affairs – High Nursing Staff Turnover in Nursing Homes Offers Important Lessons; Journal of Operations Management – The Impact of Nurse Staffing on Turnover and Quality)
Filling holes with PRN may keep the doors open today, but it does not fix the structural drivers of turnover.
Kace Premier philosophy: PRN as a bridge, not a bandage
A more effective approach is to treat PRN and contract staffing as part of a broader, retention-focused workforce strategy rather than as the entire plan.
1. Stabilize the core, then flex
Research on turnover and staffing suggests that improving baseline staffing levels and work conditions is central to reducing turnover and protecting quality. (Journal of Healthcare Management – The Race to Retain Nursing Workforce in Healthcare; International Journal of Nursing Studies – Worldwide Prevalence and Associated Factors of Nursing Staff Turnover)
In practice, that means:
• Prioritizing permanent hires for high-impact units.
• Using PRN as a temporary bridge during transitions or volume surges.
• Monitoring how often PRN is covering what should be permanent FTEs.
2. Build retention through leadership
Leadership investments are retention strategies. Reviews of nursing leadership have found that transformational and supportive leadership styles are associated with higher job satisfaction, stronger organizational commitment, and greater intention to stay. (Nursing Reports – Transformational Leadership and Nursing Retention: An Integrative Review)
Studies of leadership style also show that nurses are more likely to remain when they perceive strong, fair, and communicative leadership. (International Journal of Research and Scientific Innovation – Leadership Style and Job Satisfaction on Retention Among Nurses; Lex Localis – Influence of Nursing Leadership on Staff Retention)
For Kace Premier, that translates into partnering with organizations that are willing to invest in leadership development and align staffing decisions with healthy work environments.
3. Align staffing models with human capacity
Evidence from nursing and occupational health research indicates that long shifts and excessive working hours are consistently linked to higher burnout and intention to leave. (BMJ Open – Association of 12 h Shifts and Nurses’ Job Satisfaction, Burnout and Intention to Leave; Journal of Occupational Health – Long Working Hours and Burnout in Health Care Workers)
A retention-focused model uses PRN to prevent core staff from regularly exceeding sustainable hours, sets guardrails for consecutive shifts and weekly hours, and explicitly rejects “coverage at any cost” in favor of protecting long-term workforce capacity.
Practical implications for healthcare leaders
To convert PRN from a cost center into a stability tool, leaders can take several concrete steps.
1. Audit PRN usage against vacancy and overtime data
Compare where PRN hours are highest with where turnover, overtime, and vacancy rates are highest. High turnover has been shown to undermine quality and safety, particularly in settings such as nursing homes where consistent staffing is critical. (Health Affairs – High Nursing Staff Turnover in Nursing Homes Offers Important Lessons; International Journal of Nursing Studies – Worldwide Prevalence and Associated Factors of Nursing Staff Turnover)
If PRN is consistently used to cover chronic vacancies in the same units, you are looking at a structural staffing issue rather than a temporary gap.
2. Set clear “stability thresholds”
Define thresholds for when PRN is appropriate—such as census spikes, seasonal surges, or short-term leaves—and when volume signals deeper structural issues that require permanent roles, workflow redesign, or leadership intervention.
Use metrics such as PRN hours as a percentage of total hours, overtime per FTE, and early turnover (less than one year) by unit. These data points connect directly to the financial impact of turnover highlighted in national retention reports. (NSI National Health Care Retention & RN Staffing Report)
3. Integrate PRN into culture, not just the schedule
Even supplemental staff affect culture and quality. Studies on turnover and workplace climate note that frequent staff changes and weak team cohesion can harm both staff morale and patient outcomes. (Journal of Healthcare Management – The Race to Retain Nursing Workforce in Healthcare; Journal of Operations Management – The Impact of Nurse Staffing on Turnover and Quality)
Treat PRN clinicians as part of the team by:
• Providing quick orientation to unit norms and communication practices.
• Including them in safety huddles and debriefs.
• Clarifying how their role supports stability, not just “coverage.”
4. Tie staffing strategy to quality and financial goals
Analyses based on national retention reports and industry summaries highlight that each percentage-point change in RN turnover can cost or save the average hospital hundreds of thousands of dollars per year. (NSI National Health Care Retention & RN Staffing Report; Becker’s Hospital Review – The Cost of Nurse Turnover in 24 Numbers)
Connect staffing mix decisions directly to:
• Target reductions in turnover and vacancy.
• Improvements in patient outcomes such as falls, readmissions, and patient satisfaction.
• Labor expense goals tied to sustainable workloads, not just lower hourly rates.
If your organization is relying heavily on PRN and contract staff just to get through each schedule, you are likely managing symptoms rather than solving the retention problem. Current evidence links high turnover, long hours, and weak leadership to burnout, quality issues, and escalating labor costs.
