The scientific program, chaired by Professor Opher Baron, of the Rotman School of Management, University of Toronto, hosted a morning of research presentations on the applications of analytics to healthcare. An internationally recognized line-up of experts in different scientific disciplines presented data driven work in the context of the healthcare industry.
Each presentation explored a current challenge in the field and how analytics can offer insights to move us towards effective solutions. The presentations were calibrated for a broad audience to make the insights accessible for students, alumni, and practitioners.
4th Annual Research Roundtable: Data Analytics in Healthcare
March 23, 8:00am-1:00pm
Presentations
Opening Remarks by Opher Baron, Distinguished Professor of Operations Management, Rotman School of Management
Title: Applied Artificial Intelligence in Healthcare: From Compute to Care
Presenter: Muhammad Mamdani, PharmD, MA, MPH, Vice President, Data Science and Advanced Analytics, Unity Health Toronto
Abstract: Advances in data science and the application of artificial intelligence (AI) are having transformational impacts on society from smartphones to self-driving cars. Healthcare is among the most data-rich sectors and is well positioned to benefit from AI applications. While there has been considerable activity in health AI research, its application in clinical practice has been limited. The presentation will use case examples to review the development and implementation of data science and AI solutions into clinical practice to improve patient outcomes and hospital efficiency. Specific examples include the development and application of algorithms to improve staffing efficiency, predict emergency department patient volumes, and predict patient death and need for intensive care.

Title: How Risky is that Risk Sharing Agreement? Potential Unintended Consequences of Six Common Pharmaceutical Risk Sharing Agreements
Presenter: Greg Zaric, Professor, Ivey Business School and Editor in Chief of Health Care Management Science
Abstract: Pharmaceutical risk sharing agreements (RSAs) are commonly used to manage uncertainties in costs and/or clinical benefits when new drugs are added to a formulary. However, existing mathematical models of RSAs ignore the impact of RSAs on clinical and financial risk.

Title: Emerging opportunities for health monitoring and protection
Presenter: Ali Vahit Esensoy, PhD Adjunct Faculty, IHPME and MIE, University of Toronto, Senior Director, Data Science, Klick Consulting
Abstract: Klick Applied Sciences is an interdisciplinary research lab focused on developing digital technologies for health. One arm of our work entails investigating new approaches to measurement and prediction of health states using novel datasets, digital technologies and sensors. In this talk we will discuss the changing landscape of health data and how it enabled the Klick team to identify risk factors and symptoms for COVID-19 in the early days of the pandemic, develop a new biomarker of prediabetes, and reduce the clinician workload for symptom management for an autoimmune disorder.

Title: Pi in the Sky: Drone-delivered defibrillators for out-of-hospital cardiac arrest
Presenter: Timothy Chan, Professor, Industrial Engineering, Canada Research Chair in Novel Optimization and Analytics in Health, Department of Mechanical and Industrial Engineering, University of Toronto
Abstract: This talk presents several research projects related to optimizing drone delivery of defibrillators to out-of-hospital cardiac arrest (OHCA) victims. The first project combines optimization and queuing to design a hypothetical drone network to reduce response time to OHCAs in a large region surrounding Toronto, Ontario. The second project develops machine learning-based dispatch rules so drones are prioritized to cases where they are most likely to beat an ambulance. The third project describes initial feasibility studies of actual drone flights to deliver defibrillators.

Title: Predicting Delays in Queues with Invisible Customers
Presenter: Arik Senderovich, Assistant Professor at University of Toronto & Scientific Advisor, Product Strategy and Algorithms at mindzie
Authors: Yoav Kerner, Ricky Roet-Green, Arik Senderovich, Yaron Shaposhnik, and Yuting Yuan
Abstract: We consider queueing settings in which we observe only a subset of the arriving customers. These situations are prominent in healthcare environments in which the data on some of the patients is missing due to technological limitations or privacy concerns. For example, when the data is collected using a Real-Time Location System, some of the patients might not be wearing their electronic badges that track their locations during their visit.
In such settings, we consider the problem of predicting delays of observed customers upon their arrival. In the paper, we start off by presenting an exact analysis of the expected delay for an observed customer in M/M/1 queues, which illustrates the analytical difficulties of the problem in more general cases. We perform an empirical comparison between the performance of the theoretical solution and machine learning (ML) approaches that use various levels of information available in simulated M/M/1 data. We show that ML methods based on simple temporal differences between so called observed `events of interest’ are competitive with our theoretical predictor. We present the dependence of the approach on the proportion of invisible customers and on the traffic intensity.

Title: A fast and granular agent-based simulation model of COVID-19
Presenter: Dionne M. Aleman, PhD, PEng, Associate Professor, Industrial Engineering, University of Toronto
Abstract: Most COVID-19 projections are based on compartmental models, which require only high-level information about a disease and population to make high-level predictions. For nuanced assessment of policy interventions to slow disease spread, agent-based simulation (ABS) models that treat individuals uniquely are more appropriate but can be computationally unwieldy and even intractable. The Medical Operations Research Lab’s Pandemic Outbreak Planner (morPOP) is a computationally tractable, memory efficient ABS that considers the unique demographic, comorbidity, and behavior characteristics of each individual. It has been used to model H1N1 and pandemic influenza in the Greater Toronto Area (6 million agents) and is currently used to model COVID-19 in Newfoundland & Labrador (520,000 agents). Specific scenarios examined with morPOP include school mitigation measures and the effectiveness of NL’s travel ban, allowing public health officials to make evidence-based decisions about appropriate measures to enact.

Keynote Presentation – Bridging patient care silos: Co-location of cross functional teams to streamline patient flow
Presenters: Anita L Tucker, Professor of Operations & Technology Management, Boston University Questrom School of Business & Dr. Christopher S. Manasseh, Clinical Associate Professor, Family Medicine, Boston University School of Medicine; Vice Chair of Family Medicine Inpatient and Hospital Services, Boston Medical Center
Abstract: Boston Medical Center’s Dedicated Observation Unit uses co-located, cross-functional teams. They are equipped to treat a wider variety of more severely sick patients than the typical observation unit and have a collocated cross-functional team structure. This enables use of exclusion criteria—rather than the typical inclusion criteria—which enables the unit to efficiently treat patients. They also can take more patients, freeing up in-patient beds for others. This research tests the impact of this approach on patient outcomes and length of stay.
