quantifying clinical care: how strategic retention reduces overtime and protects operating margins

Healthcare organisations can use retention to reduce vacancy-related costs, manage overtime and enhance workforce stability.

the case for strategic retention.

Healthcare leaders are working with very tight staffing budgets. The ongoing healthcare workforce shortage means clinicians are challenging to replace, and every unfilled role can lead to weeks of scheduling pressure, overtime, and recruitment effort.

Reducing those vacancies starts with retaining experienced clinicians. Stronger retention provides healthcare organisations with a more stable workforce to plan your operations around, making it easier to ensure adequate shift cover and avoid repeatedly filling the same gaps.

That stability offers financial, operational, and clinical value. Retaining experienced clinicians can lower vacancy-related staffing costs, reduce overtime, and make scheduling more predictable. Furthermore, greater workforce stability can support better patient outcomes.

Here's how stronger retention can help healthcare organisations reduce the impact of workforce gaps and turnover.

lowering the cost of workforce gaps.

The cost of turnover continues long after a clinician leaves, and recruitment is only one element of this. While a position remains vacant, healthcare organisations still need to maintain the necessary workforce capacity to deliver care. That can mean incurring additional costs to cover the gap until a permanent replacement is in place.

A 2026 Nursing Outlook study found that 75.5% of backfill hours were covered by agency staff. When an agency nurse was used to cover a vacancy, the researchers calculated an average turnover cost of $85,498 per nurse. Across the healthcare system studied, annual turnover costs reached $27.9 million.

Stronger nurse retention can reduce how often healthcare organisations incur these costs. For hard-to-fill clinical roles in particular, preventing avoidable departures can have a meaningful effect on staffing expenditure.

Actionable Tip: 

Calculate the cost of turnover in your hardest-to-fill clinical roles, including the cost of covering vacancies as well as recruitment and induction. Use the results to build the financial case for retaining staff in the roles where turnover costs the most.

create more predictable shift schedules.

A vacancy can disrupt schedules for much longer than just a few shifts. The same Nursing Outlook research found that nursing vacancies took an average of 21.7 weeks to fill, leaving managers to plan months of cover with fewer permanent clinicians available.

Retention gives managers more certainty about the capacity, skills, and qualifications available across their teams. This makes it easier to plan shifts further in advance and identify gaps in cover before you need to make last-minute changes.

This visibility is particularly important for compliance. Healthcare organisations need to maintain cover while meeting requirements for working hours, rest periods, and clinical qualifications. Retaining experienced clinicians gives you more options to balance these requirements without repeatedly putting extra pressure on the same individuals.

Scheduling technology can support this process by matching availability, qualifications, and working-hour limits with cover needs, reducing the manual effort needed to create compliant rotas.

Actionable Tip: 

Review recurring gaps in cover alongside staff turnover patterns. Identify the roles, teams, and shifts where vacancies are creating the most rota pressure.

reduce overtime costs.

Overtime can provide short-term cover when a vacancy leaves a team short-staffed. But when that vacancy lasts for months, additional hours can become a recurring expense that puts labour budgets under pressure.

UConn Health highlights just how significant this expense can become. A state audit found that employees earned $19.4 million in overtime, including shift premiums. UConn Health said workforce shortages and difficulties in filling roles contributed to overtime, while contractual provisions, including double and triple time rates, could drive costs even higher. The audit recommended increasing staffing levels to reduce the reliance on significant overtime.

For healthcare organisations facing similar challenges, stronger retention can help by cutting down on vacancies that require your existing clinicians to work additional hours over extended periods.

Actionable Tip: 

Compare overtime hours and costs with turnover rates by team or clinical role. Use the results to identify where persistent vacancies are putting the most pressure on labour budgets and prioritise retention efforts accordingly.

ease administrative pressure.

High turnover not only creates replacement costs; it also adds to the administrative workload for nurse managers. Each departure can mean another round of staffing, recruitment, and onboarding tasks on top of their existing responsibilities.

A 2024 Journal of Nursing Administration study found that high turnover, broad spans of control, and the time spent on staffing, scheduling, and recruitment can put significant pressure on the nurse manager role.

That administrative burden is also a major source of frustration. McKinsey found that nine of the 10 activities nurse managers identified as most frustrating were administrative tasks, including managing call-out cover, incident reports, and complaints.

Stronger retention can reduce one source of this recurring workload. Fewer departures mean fewer vacancies, recruitment cycles, and onboarding requirements for managers to contend with, giving you more capacity to engage with your teams and focus on clinical priorities.

Actionable Tip: 

Identify which staffing, scheduling, recruitment, and onboarding tasks consume the most management time. Simplify workflows and automate repetitive tasks so nurse managers have more time to engage with their teams, support retention, and address care priorities.

support better patient outcomes.

Workforce stability can influence the quality of care patients receive. When experienced clinicians stay, healthcare organisations maintain greater continuity across the teams providing that care.

A BMJ study utilising nine years of monthly healthcare worker and patient data found that lower staff turnover rates for nurses and senior doctors were associated with improved health outcomes. Specifically for nurses, higher monthly turnover was linked to an increased 30-day mortality risk, especially among patients admitted due to emergencies.

The findings show why the value of retention should not be measured solely by workforce costs. Patient outcomes can provide an additional indicator of the impact linked to a more stable workforce.

Practical Tip: 

Evaluate retention alongside relevant patient quality and safety measures. This can help leaders understand if changes in workforce stability are reflected in patient outcomes.

make retention a core workforce strategy.

Healthcare organisations can strengthen retention by addressing the conditions that shape the clinician experience. Workmonitor 2026 highlights factors like workload, career development and manager support as important in their decision to stay.

The measures outlined here can help leaders decide where to start. Identify where turnover is creating the most significant financial and operational strain, then concentrate retention efforts on the roles and teams where they can achieve the greatest impact. This could involve improving workforce development, establishing clearer upskilling and reskilling opportunities, or empowering managers with more capacity to support their teams.

Randstad can help healthcare organisations identify workforce and skills shortages, strengthen workforce planning and integrate retention into a long-term workforce strategy. With stronger retention, leaders can devote less time to addressing recurring vacancies and more time building the workforce capacity their organisation needs.
