Systems reengineering to improve care

May 30, 2014 in Medical Technology

A strategy most often applied to industries such as manufacturing and aviation might unlock the potential for better care at lower cost, according to a new report from the President’s Council of Advisors on Science and Technology.

Systems engineering, common in other sectors of the economy, is an interdisciplinary approach to analyzing, designing and managing complex systems, with the aim of improving their efficiency, reliability and productivity.

For example, the PCAST report, “Better Health Care and Lower Costs: Accelerating Improvement Through Systems Engineering,” points out that, “by using tools such as alerts, redundancies, checklists, and systems that adjust for the human factor, U.S. commercial airlines have reduced fatalities from hundreds in the 1960s to approaching zero now, with the risk of dying now at 1 in 45 million flights. They have also been used in fields as diverse as manufacturing, space stations and satellites, and education.”

The study makes the case that similiar improvement strategies – so far only applied in a limited way in healthcare thanks largely the the strictures of the existing fee-for-service model – will be key to smarter use of data for better care delivery.

“The ability to look at high-quality data, measurement and analytics in real time is key to systems engineering in any sector of the economy but particularly in healthcare,” said Christine K. Cassel, MD, president and CEO of the National Quality Forum and co-chair of the PCAST Systems Engineering in Health Care Working Group, in a press statement.

“To improve healthcare, good, relevant, standardized and patient-centered measures and data must be more readily available in order for patients and providers to make more informed decisions and to drive improvements in care,” she added.

The PCAST report outlines several steps for applying systems engineering principles to healthcare, including increasing and improving the nationwide data sharing infrastructure, providing technical assistance to providers and training health professionals in systems engineering approaches.

Systems engineering has “often produced dramatically positive results in the small number of health care organizations that have incorporated it into their processes,” according to PCAST

A fundamental change in payment policies is essential to spurring wider adoption of these strategies, according to the report. Also critical will be higher-quality data measurement and analysis – with electronic health records and other health IT as essential tools.

PCAST recommends seven steps toward a systems engineering approach:
