Who is this presentation for?

  • Professionals interested in the application of machine learning to improving patient care

Prerequisite knowledge

  • Familiarity with machine learning (useful but not required)

What you'll learn

  • Understand how to study and model rare events in the healthcare space using small and medium data approaches on a subset of big data to improve patient care
  • Discover tips for working well with a range of stakeholders and how to engage all project members so everyone is invested in the project and nobody is surprised

Description

Many hospitals rely on rapid response teams (RRTs) to intervene when patients experience a rapid decline. When hospital staff observe a patient in decline, they raise an RRT event, summoning the team to the patient’s bedside.

RRT events are rare, occurring in less than 0.5% of all hospital patients, but response teams are a substantial resource, deployed to achieve the best possible patient outcomes. However, optimizing their utilization is a constant challenge. Teams, include medical professionals versed in critical care, use the time between routine rounds and events to monitor patients, looking for early indications of possible decline. Sometimes it’s clear who warrants additional attention, but often shift changes, patient movements, and subtle changes in patient conditions complicate the process.

Emily Spahn explores the creation of a patient-risk model that uses machine-learning techniques to produce a patient risk score, in order to assist the RRT in focusing their efforts. This proof-of-concept project uses electronic health records to model the likelihood of a patient experiencing near future health declines indicative of an RRT event. The model produces a simple patient risk score on a scale of 0 to 10. By highlighting patients at risk, the hope is that early intervention can avoid an RRT event altogether.

Emily discusses the technical challenges of this modeling effort—which uses tools from the Hadoop and Python ecosystems to study these rare events—and shares the approaches taken to bring consultants, technology providers, and hospital administration and staff onto same page, guiding the project toward success.
