Improving Planned Surgical Case Duration Accuracy by Leveraging the EHR and Predictive Modeling

Study Overview
=================
Brief Summary
-----------------
The investigators are studying the duration it takes surgeons to complete their respective surgical cases. The hospital hopes to improve the overall operating room scheduling accuracy from this project.

Official Title
-----------------
Improving Planned Surgical Case Duration Accuracy by Leveraging the EHR and Predictive Modeling - A Randomized Control Trial

Conditions
-----------------
Operative Time

Intervention / Treatment
-----------------
* Other: standard scheduling process
* Other: assigned a planned case duration value from predictive model


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: A surgeon or OR staff member in the Department of Surgery Gynecology and Colorectal service Exclusion Criteria: Any new surgeon that starts their practice during the study Surgery will take place at a location other than the Main hospital or Josie Robertson Surgical Center Cases where input data was not available prior to the prediction generation including late add-on cases such as urgent and emergent cases that are placed on the schedule less than 24 hours before the surgery

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| standard scheduling process<br>Scheduling office assigns start time and room for case and places case on schedule. At this point a default case duration is evaluated by the scheduling office, to see if the value is considered excessively short or excessively long. | Other: standard scheduling process<br>* Scheduling office assigns start time and room for case and places case on schedule. At this point a default case duration is evaluated by the scheduling office, to see if the value is considered excessively short or excessively long. Depending on the assessment, the scheduling office will either keep the default value, use the value that the surgeon placed in the notes (if available), or the scheduling office provides their own estimation.<br>|
| assigned a planned case duration value from predictive model<br>Predictive model calculates new duration for case at 3AM the day before surgery, and the predictions are made available on a SecureShare-site. | Other: assigned a planned case duration value from predictive model<br>* Predictive model calculates new duration for case at 3AM the day before surgery, and the predictions are made available on a SecureShare-site. Model predictions are then read by scheduling manager sometime between 7am-10am from the SecureShare site, and the scheduling manager will in EPIC/OpTime, overwrite the current estimate with the new duration value that was generated by the predictive model.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| duration it takes surgeons to complete their respective surgical cases | All Gynecology (GYN) and Colorectal (CRS) Surgeons at MSKCC will be included. To test the hypothesis that the developed surgical case duration prediction model compared to the current process of estimating surgical case durations, will show improved prediction accuracy, measured by mean absolute error. | 1 year |
