Surgical Case Duration Accuracy

Can you afford to say no to 30% higher case duration accuracy for your operating room?

Case duration accuracy is essential for running an efficient operating room. It’s the building block of your plan. Everything else you do is built upon this simple attribute. You use the case duration for determining how many cases you can do in each operating room and in what order you will do them. You also rely on its accuracy to decide the number of staff you will need at different hours. It impacts your planning for your pre-op area, your PACU bays, and even has ramifications for when beds need to be available for the patient to go back to their ward.

You would think an attribute with such profound effect on the operations of not only the operating room but also the hospital at large would be scrutinized very closely. Yet, it seems most organizations have bought into the idea that the best they can do is rely on simple historical averages and surgical team estimates. It has been shown over and over in academic publications that such simplistic approaches are inaccurate and do have costly consequences on operating suite utilization and patient, physician, and staff satisfaction.

If your hospital is using an EMR such as Epic or Cerner, you probably feel pretty good when their scheduling module gives you the option to use their “prediction” for case duration. If you dig deeper, this prediction is some variation of taking the last say 10 procedures of the given type, maybe throwing away the highest and lowest of the bunch and doing an average! Basically using 5th grade math on sample size of 10 to decide the single most important attribute of your planning for a multimillion dollar resource!

Think about all the possible factors that impact a procedure:

  • Patient
  • Providers
    • Surgeon(s)
    • Anesthesiologist(s)
    • Scrub nurse(s) and tech(s)
    • Circulator nurse(s) and tech(s)
  • Facility / Room
    • Bed census
    • Equipment
    • Staff
    • Day of week
    • Time of day
  • Procedure
    • Procedure type
    • Surgeon comments
    • Procedure modifiers
    • Anesthesia type
    • Implants/Tissues
  • Prior Events
    • Timing of prior perioperative milestones
    • Case delays
    • Cancellations
    • Turnover

Any single of one of these factors can have drastic impact on how the case will progress and the duration of the surgery. Now let’s think back to what our scheduling system used! We throw all of this info (which we incidentally capture & document anyways) away and just picked the procedure type. Is it any wonder why such predictions can be grossly inaccurate?

Let’s think of an analogy! Imagine you wanted to drive from point A to point B! You rely on an application such as Google Maps or Waze to tell you how long it will take you to make the trip. The app can take a number of factors into consideration: distance, possible routes, traffic conditions, current construction projects, weather conditions, …. Very similar to our surgical case, any number of these factors can impact the duration of the trip. Would you rely on an app that throw all this info out except for the distance?

The good news is that we don’t have to settle for just one dimension (procedure type) and only a handful of data points and simple math! With today’s technology, we can take all the factors we listed above into consideration. We can run multiple sophisticated algorithms over all of our data and pick the ones with the best predictive ability! We can continuously train these algorithms as new information is captured. Every day that your team is performing more cases, they are creating more data to build smarter predictions from. It’s a shame that for many, this throve of insight is sitting unused in an EMR database and not being leveraged to make your team more successful.

At Leap Rail, we put over 1,500 distinct dimensions from your existing data in your EMR to use for predicting the surgical case duration. In our deployments for our customers, we have achieved over 30% higher accuracy in predicting case duration. This improved level of accuracy has allowed our customers to have a much better visibility into their operations. They can plan for rooms, resources, equipment, and staff much more confidently. They can give physicians reliable start times or when their add-on case might be accommodated with higher confidence.

By using Leap Rail’s state of art technology and benefiting from their existing data through artificial intelligence and machine learning, our customers are not only delivering a higher quality of care, they are a lot more efficient with their resources, and their physicians and surgical teams are a lot more satisfied

Are you curious if your organization is ready to take advantage of artificial intelligence and machine learning for your perioperative environment? We have developed an AI Readiness Survey just to help you answer this question. It only takes 2-minute to complete and will tell you how big of an opportunity your organization is sitting on without realizing! What are you waiting for?
