Rising costs, medical errors, and low quality in healthcare reflect problems with system organization. NECSI's healthcare systems research focuses on improving the structure of provider organizations: how to lower costs, improve preventative medicine, and enhance patient care—including dramatic reductions in medical errors.


Lowering Costs, Improving Quality

NECSI research analyzes how healthcare costs and quality can be improved, from prevention to complex diagnosis.

Improving Organization

The public health system, NECSI research suggests, can be organized better to promote everything from efficiency to infection control.

Global Response to Health Threats

In the era of global connectivity, it is easier than ever for epidemics to spiral into pandemics. NECSI analysis shows how best to contain them.
