P05 - Improving Care Transitions through Risk Reduction with Machine Learning Support

‐ Mar 24, 2021 10:00am

Problem: The ambulatory care management team at Carilion Clinic lacked the necessary tools to demonstrate readmission risk reduction for patients undergoing care transitions.

Purpose: This quality improvement project aimed to determine if implementing a real-time workflow management system which supported the prioritization, intervention tracking, and coordination of transitions of care, would result in readmission avoidance through risk reduction.

Background: The accountable care strategies team implemented an electronic transition tracking tool (T3), as one aspect of Carilion’s readmission reduction program.

Evidence from the literature: Approximately 20% of Medicare beneficiaries are readmitted within 30 days following hospital- or facility-based care (Fischer et al., 2014). Many health systems across the country have developed strategies to reduce hospital readmissions after the passage of the Patient Protection and Affordable Care Act and its requirement for the implementation of a hospital readmissions reduction program (ACA, 2010). While there are a variety of readmission risk stratification tools used to identify patients, the predictive performance of these tools, according to Kansagara et al., (2011), has been marginal due in part to the complex factors contributing to a readmission. These researchers recommend incorporating a larger data set to include social determinants of health (Kansagara et al., 2011). Patient’s social determinants have a significant impact on their readmission risk, thus ambulatory care programs which address these factors are essential (Calvillo-King et al., 2013).

EBP question: 1) Is there an impact on readmission for a patient who undergoes risk reduction strategies by a nurse using an automated patient prioritization tool with predictive interventions?

Methods: The ambulatory care management team uses a relationship-based model, partnering with patients in self-care which is grounded in Dorothea Orem’s theory of self-care (Petiprin, 2016). The aim is to support personal agency in the achievement of effective self-management. A tool was needed to replace a manual system which could identify and prioritize at risk patients and track interventions and readmissions. A real-time data system was implemented called T3; it aggregates patients from both in and out of network hospitals. T3 also ingests information from Jvion, a machine-learning platform that provides a readmission risk scoring and associated interventions. A dashboard displays patients and their risk scores, along with recommended interventions. Ambulatory care nurses working remotely select a patient for outreach, review machine-recommended interventions, and use nursing judgement for a patient-centric approach. Readmissions prevented are recorded using specific criteria.

Outcomes: On average. 2200 patients were managed each month and received risk reduction interventions. Over 11 months, 212 patients had a readmission prevented. With the average cost of a hospital stay at $11,200.00, these 212 prevented readmissions would have cost well over 2 million dollars. Most importantly, the team saved patients from sustaining additional health complications due to a readmission.

Implications for practice: Health systems focusing on readmission reduction need to consider using a predictive tool which incorporates social determinants of health and recommends targeted interventions. Prioritizing discharged patients, managing and tracking interventions, and recording readmissions prevented by ambulatory care nurses will demonstrate improved quality of care transitions.

Learning Objective:

  • After completing this learning activity, the participant will be able to assess innovations being used by other professionals in the specialty and evaluate the potential of implementing the improvements into practice.
