Seeing Workforce Variability Before It Becomes Overtime

Workforce shortages are often treated as staffing problems. Our recent study suggests another perspective: when hospitals make workforce variation visible earlier, they may improve redeployment decisions, reduce reactive overtime, and strengthen workforce governance.

Hospitals rarely operate with perfectly stable demand.

Occupancy changes.

Professionals become unexpectedly unavailable.

Vacancies remain open.

Patient complexity varies.

One clinical area may experience a staffing deficit while another temporarily has capacity that could be safely redeployed.

The traditional response to these situations is often reactive:

a gap appears, and additional coverage is requested.

But what if the organization could identify the imbalance before overtime became necessary?

This question was central to our recently published study, Visual Management of Nursing Staffing to Improve Workforce Balance and Reduce Overtime Coverage: A Longitudinal Quality Improvement Study, in IJQHC Communications.

The intervention was not simply a dashboard

The visual management system combined a Kanban-based workforce board with a structured managerial routine.

Information on planned staffing, absences, vacancies, hospital occupancy, internal redeployment, overtime coverage, and related expenditure was brought into the same decision process.

The underlying logic was:

make imbalance visible → evaluate available capacity → redeploy safely when possible → use overtime as an escalation option

This distinction matters.

Visual management was not treated as a technology project.

It was a decision-support and governance process.

What did we observe?

The study analysed monthly data from January 2024 through May 2026.

Before implementation, mean monthly overtime coverage was 108.8 events.

After implementation, it decreased to 23.4 events, representing a 78.4% reduction.

Mean monthly overtime-related expenditure decreased from BRL 22,221.69 to BRL 6,071.42, a 72.7% reduction.

During follow-up, 459 internal staff redeployments were recorded, with estimated avoided expenditure of approximately BRL 99,916.

Hospital occupancy remained sustained during the post-implementation period.

Interrupted time-series analysis also identified a substantial immediate level reduction following implementation.

These findings should, however, be interpreted appropriately.

This was a single-centre quality improvement study. The intervention was temporally associated with the observed changes; it does not establish that visual management alone caused them.

That limitation is important.

But so is the operational question raised by the findings.

Perhaps the problem is not only workforce quantity

Healthcare workforce discussions frequently focus on numbers:

How many professionals do we have?

How many vacancies exist?

How much overtime are we using?

These are necessary questions.

But they may not be sufficient.

Another set of questions concerns organizational capability:

Can leaders see staffing imbalance early?

Can they compare demand and available capacity across units?

Can professionals be safely redeployed?

Are decisions based on shared information?

Is overtime the first response—or the final escalation option?

These are workforce governance questions.

Visibility changes when decisions happen

One of the most relevant lessons from the intervention was not simply that information became available.

It became available before the decision.

That difference is fundamental.

Retrospective indicators explain what happened.

Operational visibility can influence what happens next.

If a staffing deficit is recognized only after a unit is already under pressure, options are limited.

If the same deficit is identified earlier, managers may have time to evaluate capacity elsewhere, coordinate redistribution, and avoid unnecessary extraordinary coverage.

Visibility therefore changes the timing of management.

And timing changes the range of possible decisions.

From staffing management to workforce governance

This also connects with our previous research on organizational maturity and quality governance.

In Organizational Maturity as a Tool for Quality Governance, we observed that organizational maturity evolved through capabilities involving coordination, monitoring, standardization, and sustained improvement.

The workforce intervention provides a practical example of how those capabilities can become visible in daily operations.

Organizational maturity supports governance.

Governance organizes information and accountability.

Operational visibility supports earlier decisions.

Those decisions can influence measurable outcomes.

This suggests that workforce management should not be separated from the broader discussion on healthcare quality governance.

More data are not necessarily the answer

Hospitals already generate enormous amounts of information.

The challenge is often not data scarcity.

It is connecting the right information to the right decision at the right time.

A dashboard without a management routine may become decoration.

An indicator without responsibility may become noise.

Visibility without authority to act may produce frustration rather than improvement.

For visual management to function as a governance mechanism, information must be connected to:

  • responsibility;

  • decision-making;

  • escalation rules;

  • coordination between units;

  • follow-up;

  • and organizational learning.

Questions for healthcare leaders

Instead of asking only whether staffing is adequate, perhaps we should also ask:

Can we detect imbalance before it becomes overtime?

Do we distinguish structural workforce shortages from temporary operational variation?

Can capacity be safely shared across units?

Are staffing, absenteeism, occupancy, and demand analysed together?

Do our dashboards trigger decisions—or simply produce reports?

Do recurring overtime events generate organizational learning?

These questions move the discussion from scheduling toward governance.

And that may be increasingly important as hospitals face workforce shortages, financial constraints, rising complexity, and greater pressure to maintain safe care.

The objective should not be to minimize staffing.

It should be to use available workforce capacity more intelligently while protecting patients and professionals.

Perhaps this is the broader lesson from visual workforce management:

before adding resources, organizations should first understand whether they can see, coordinate, and use the resources they already have.
