Healthcare Systems Engineering

Our Mission

Northeastern University’s Healthcare Systems Engineering (HSyE) program is a university-level Institute that has focused on improving healthcare efficiency, quality, logistics, safety, flow, effectiveness, and access for more than 30 years. We have a simple mission: To broadly impact healthcare improvement through education, research, and application in systems engineering methods. We accomplish this mission through our HSyE undergraduate and graduate academic programs, national experiential coop education and summer internship programs, three federally-awarded healthcare IE centers, competitive scholarships, and strategic partnerships. We rely on deep industry-university partnerships to advance the shared missions of healthcare improvement and workforce development.

What Is Systems Engineering?

Healthcare Systems Engineering (HSE) methods range from lean six-sigma tools to advanced mathematical models used in many other industries to study, improve, and optimize process quality, delays, cost, efficiency, and effectiveness - national priorities also identified by the IOM. Recent healthcare applications include improvements in scheduling, readmissions, cost reductions, cancer care, and health services planning.

Systems engineers use a variety of methods to model, analyze, predict, improve, and optimize the performance of complex systems, sometimes supported by informatics to harness information in new and innovative ways. While these methods have a long but periodic history of use within clinical, operations, and administrative healthcare processes, their focus has been insignificantly positioned to dramatically move the U.S. healthcare system forward. Within healthcare, systems engineering applications span the spectrum from local "micro-system" process improvement activities to more global "macro-system" optimization problems, ranging methodologically from simple process improvement methods to advanced mathematical and computer modeling.

Why Healthcare?

Healthcare is the largest industry in the United States yet riddled with system problems, costing over $2.3 trillion per year, comprising 16-18% of our gross domestic product, and increasing steadily at twice the rate of inflation. Numerous studies agree that roughly 30% of total U.S. healthcare costs are attributable to inefficient poorly designed processes, prompting publications by the National Academy of Engineering (NAE) and Institute of Medicine (IOM) to advocate much greater application of systems engineering, operations research, management science, and related methods used in other industries. Each IOM dimensions of the care system - efficiency, effectiveness, safety, access, equity, patient-centered - can be improved by systems engineering, with examples including patient flow, appointment and staff scheduling, facility layout, disease screening, treatment optimization, regional planning, and pandemic response problems.

The estimated national impact of adverse events and medical errors due to poor processes are staggering, including 1.4 million injured patients, millions of hospital days, 98,000 deaths, and almost $9 billion annually. Significant practice and process variability abounds, a far cry from "six sigma" aspirations in manufacturing and with estimates that 57,000 additional patients would survive and $9.5 million would be saved annually if all U.S. hospitals simply performed as well as the current best. The increasing interest within many hospitals in such manufacturing engineering approaches as lean, quality control, and others underscore the pressure to produce higher quality care, more efficiently, at lower costs. Yet progress remains frustratingly slow.
