Data-driven OR scheduling algorithms to smooth patient outflows, maximize throughput and reduce surgical backlogs.

An Opportunity to Help

COVID-19 paralyzed healthcare systems worldwide, delaying millions of procedures and creating an unprecedented surgical backlog.

One promising approach to reducing this backlog uses data models to reduce variability and optimize elective surgical schedules. Far better at identifying effective resource combinations than humans, these models can significantly aid decision-makers if properly integrated.


Decision variables required for a block schedule - impossible to optimize without digital assistance.

The Impact of Scheduling

Research from the Institute for Healthcare Improvement found that nearly 70% of all the diversions from the ICU were associated with variability in the elective caseload. When elective surgery peaked, so did diversions. In fact, up to 80% of variability in the OR is due to variations in the elective caseload—more than from emergencies, cancellations or add-on cases.

Addressing variability in the schedule smooths peaks in the patient flow, prevents ICU diversions, and improves surgical throughput. Osler OR tackles this variability to improve outcomes for patients, and remove barriers for providers.

Osler | The Surgical Scheduling Solution

Osler OR is a web based application that trains on a hospital’s historical data. The trained system can then easily be used in many ways:

  • Prediction

    Osler OR can predict the performance of a new schedule, allowing administrators to observe the impact of changes before they’re made.

  • Schedule Generation

    Osler OR generates block schedules in minutes based on historical performance, schedule requirements, and hospital constraints. If something changes, hospitals are now only minutes away from the new best schedule

  • Reporting, Analytics and Informatics

    Osler OR presents surgical data in a configurable reporting dashboard with easily digested trends and plots.

Osler’s Impacts

Osler OR helps decision support specialists optimize surgical scheduling.

Peaks in surgical demand stress hospital resources and create downstream challenges. Osler will help planners optimize their OR block schedules to reduce variability and create a more uniform pattern of resource utilization.

Increase OR throughput to address the surgical backlog. Osler schedules optimize for OR utilization, on-time-ends, and other important key performance indicators for greater all-around performance with existing resources.

Osler OR generates schedules in minutes, allowing administrators to create a new best schedule if circumstances change. The performance of new schedules is predicted so new processes can be simulated before implementation.

Success Criteria

Osler will be judged by its improvements in factors influencing throughput, utilization, and consistent performance of the perioperative department.
