Until recently, clinical practitioners focused almost exclusively on providing individual patients with safe and accurate treatment. Physicians favored methods that yielded the best outcomes for patients solely on a case-by-case basis.
However, the needs of the medical sector are changing. An increase in demand has highlighted the variation that exists in patient treatments. Approaching surgeries on a case-by-case basis inherently adds an element of inconsistency for both patient outcomes and patient costs. To tackle this rise in demand and address the variable patient outcomes, there is a need for doctors to shift their focus to a view that includes both accuracy and clinical variability.
The difference in patient expenses for the same procedures, even though their needs and circumstances are identical, can be sizable. Unfortunately, traditional analytics do not allow medical establishments to get a handle on these variations, contributing to the estimated $750 billion of wasted healthcare spending every year.
One of the driving factors in surgical variation and waste is the use of different supplies for the same clinical purpose — some with substantial cost and outcomes variances. Significant progress can be achieved by identifying and reducing disparate supply utilization within comparable supply categories.
Comparable supply categories, custom-built by Olive clinical experts, group supply items that surgeons can substitute for another. For example, there are currently 199 items identified in the Olive supply category for biopsy forceps. Under traditional UNSPSC commodity classification, these items would be fragmented across 10 different categories (endoscopic specimen retrieval forceps, endoscopic retrievers or sets, surgical clamps or clips or forceps, etc.) rendering direct comparison impossible. Olive’s innovative categorization process enables her to identify where variation exists and to find lower-cost supply options. Put simply, Olive identifies ways to reduce the cost of a procedure without changing the technique of the procedure.
The system currently includes five hierarchical layers and 5,800-plus distinct categories covering more than 1.6 million items. The supply use variation is viewed relative to specific procedures and surgical cohorts, allowing surgeons to see exactly where cost savings are possible. Along with the comparable supply items, practitioners can also analyze outcome and efficiency measures within the cohort, producing a more comprehensive picture of the opportunity.
The number of supply items on the market is enormous, with the average hospital using more than 200,000 distinct supplies within the surgical space. Given this large number, manual categorization would be incredibly cumbersome and time-consuming for human workers. But never fear, Olive is up to the task! Her automated system of layered machine learning models predict the placement of supply items into categories based on an item’s name, manufacturer information and cost.
Olive’s system uses a model factory, or series of independently trained machine learning models, with binary classification methods for each supply category. Olive then combines and evaluates the results from all models to determine an item’s best category placement. Using many binary machine learning models, as opposed to a single multi-class model, has proven to be more accurate and trustworthy in the automated process. Olive’s superhuman ability to rapidly categorize supplies facilitates the discovery of supply variation and opportunities within relevant cohorts.
Physicians will always need to focus on quality and the best outcomes for their patients. However, there is a pressing need to expand physician perspectives to understand and reduce unnecessary variation leading to waste. Positioning this data with the correct clinically relevant factors, such as comparable supply categories, is crucial.
Providers must take the time to dig into their data and apply new tools that allow them to gain insight into the variation, then act. Machine learning models, such as the ones deployed by Olive, are enabling clinically driven insights that can change the way physicians deliver care. Tackling clinical variability with a clinically driven approach is the first step toward eliminating a healthcare system’s wasted spending.
Healthcare looks quite different than it did just a few short years ago. The COVID-19 crisis has created a distinct “before” and “after” for the world, and especially for healthcare.
Artificial intelligence (AI) is revolutionizing healthcare data analytics and changing the way we predict, learn and act based on insights gained through AI-powered data models.
