Hospital operational efficiency: how to improve results

Hospital operational efficiency is not a long-term goal; it is already a precondition for operating profitably. Data from the Anahp Observatory 2025 shows that total expense per hospital discharge reached R$ 23,563.42 in 2024, at a time when net revenue per discharge fell 7.7% compared with the previous year. Hospitals that do not control their operational processes therefore absorb this pressure directly in their margins.

Operational efficiency does not mean cutting costs indiscriminately, however. It means doing more with the same resources, reducing invisible waste and making sure each stage of the process (from care to payment) runs without rework.

The six practices below can be applied immediately, with a direct impact on results.

What hospital operational efficiency is

Hospital operational efficiency is a healthcare institution’s ability to deliver its services with the least possible waste of resources (time, staff, materials and capital). All of this without compromising the quality of care.

That is exactly why it differs from cost cutting. Cutting costs reduces inputs; operational efficiency optimizes the use of the inputs that already exist. A hospital that cuts its nursing staff to save money, but raises its average length of stay and hospital infection rate, reduces costs and destroys efficiency at the same time.

The starting point is always diagnosis: understanding where waste happens, what that waste costs and which process changes deliver the greatest return. The following practices act on these fundamental points.

1. Reduce the average length of stay

The average length of stay (ALOS) is one of the operational indicators with the greatest direct financial impact. In 2024, the average at Anahp hospitals reached 3.99 days, the lowest level in four years, the result of a systematic management effort.

Each day less in the hospital frees a bed for a new patient, speeds up revenue turnover and reduces hospitality, nursing and materials costs. Reducing ALOS does not depend on clinically inappropriate early discharge, but on eliminating unnecessary waiting days: waiting for a test, waiting for a result, waiting for a physician to sign the discharge.

The most effective levers are: standardizing discharge criteria, integrating clinical and administrative teams, and using systems that forecast discharge in advance to organize bed flow.

2. Control staff costs with a focus on productivity

At 39.03% of total expenses, staff is a hospital’s largest cost — and the least flexible. Cutting headcount is rarely the right answer; increasing the productivity of the existing team almost always is.

The path starts with measurement. How many discharges per bed does each team produce? What is the average time of each stage of the care process? Where is there idle time and where is there overload? Without this data, any staffing decision is based on perception, not evidence.

With the data in hand, it is possible to redistribute workload, identify scheduling bottlenecks and make well-grounded hiring or reallocation decisions. Staff productivity is not just an HR issue but a central financial indicator.

3. Automate the revenue cycle

Manual billing is one of the biggest sources of invisible waste in Brazilian hospitals. Coding errors, incomplete documentation and late submission cause denials, rework and payment delays, without the impact showing up clearly in conventional reports.

In 2024, the average managerial initial denial rate at Anahp hospitals was 15.89%. Much of this volume stems from avoidable failures in the billing process: information that differs between the medical record and the form, procedures not documented at the right time, incorrect codes.

Automating the revenue cycle (from clinical auditing to issuing the XML) reduces these errors at the source, speeds up claim submission and shortens the average time to payment. The result is more revenue captured and less working capital tied up.

4. Actively manage the inventory of materials and drugs

Materials and drugs account for a significant share of hospital expenses — and one of the most prone to waste. Expired products, excess idle stock, duplicate purchases and unrecorded use of OPME are recurring sources of loss that go unnoticed in day‑to‑day operations.

Efficient inventory management starts with adopting methods such as FEFO (first expired, first out) for drugs and materials with an expiration date, and with periodic inventory counts that reconcile what was used with what was billed. Discrepancies between these two numbers point to either waste or underbilling, and both compromise financial results.

Integrating the inventory system with billing makes it possible to identify, in real time, whether a material used in care was properly recorded on the patient’s claim.

5. Standardize care protocols

Clinical variability is cost variability. When two physicians take different approaches to the same diagnosis (one orders three tests, the other orders seven), the hospital bears the difference without necessarily getting a better clinical outcome.

Standardized care protocols reduce this variability by defining, based on evidence, which tests, drugs and procedures are indicated for each condition. In addition to improving the quality of care, well-implemented protocols reduce the average cost per hospital stay and make negotiations with payers easier, since they gain more predictability about what will be billed.

Adopting protocols does not limit clinical autonomy; it sets a quality floor and reduces unnecessary variability.

6. Monitor operational indicators every week

Reactive management is expensive. When managers only find out at the monthly close that the average time to payment has gone up, weeks of problems have already piled up. The same goes for the occupancy rate, the denial rate and the cost per discharge.

Weekly monitoring of operational indicators makes it possible to spot deviations early, before they become a trend. There is no need to track dozens of metrics: a dashboard with five to seven key indicators, updated every week, already changes management’s ability to respond.

The priority indicators for weekly tracking are: average time to payment, initial denial rate, operational occupancy rate, average length of stay and volume of open claims by payer.

Efficiency is much more than cutting expenses

Efficient hospitals are not necessarily the ones that spend the least. They are the ones that know where every real goes, identify waste and have processes that work without depending on constant manual effort.

The six practices presented here tackle the main drivers of inefficiency. Each one, implemented on its own, already delivers results, but together they build a more predictable, more profitable and more sustainable operation.

Rivio was founded to transform hospital management through artificial intelligence. In a landscape under growing pressure from costs, regulatory complexity and operational inefficiencies, we believe technology is the way to bring financial predictability, scale and intelligence back to healthcare’s administrative processes.

By automating analysis, reducing rework and supporting decisions with reliable data, we help hospitals operate more efficiently, free up their teams’ time and create the conditions to focus on what really matters: quality of care and the patient experience.

FAQ: frequently asked questions about operational efficiency in hospitals

What is operational efficiency in hospitals?

It is the ability to deliver healthcare services with the least possible waste of resources such as time, staff, materials and capital, without compromising the quality of care. Unlike cost cutting, operational efficiency optimizes the use of existing resources.

How can hospitals reduce costs without compromising quality?

The main levers are: reducing the average length of stay, automating billing to lower denials, actively managing inventory, standardizing care protocols and monitoring indicators weekly. These actions tackle waste without compromising the quality of care.

Which indicators should be monitored to improve hospital efficiency?

The most relevant for weekly tracking are: average time to payment, initial denial rate, operational occupancy rate, average length of stay and volume of open claims by payer. With these five data points, managers have visibility into the main cost and revenue drivers of the operation.
