Intelligent Early Warning: A Comparison of the Rothman Index with MEWS and NEWS


PeraHealth is transforming healthcare through the intelligent use of data. By providing a clear, contextual picture of patient condition at both the organizational and individual patient level, PeraHealth solutions enable healthcare organizations to improve clinical decision support and enhance the care delivery process. Helping clinicians to identify and intervene earlier on at-risk patients helps address a range of clinical and operational imperatives including improving patient safety, improving performance in value based purchasing programs, and driving operational efficiencies.

The focus of this paper is on how PeraHealth solutions compare to other early warning systems; specifically, the challenges facing early warning systems and how the Rothman Index (RI) and PeraHealth’s clinical surveillance solutions provide clinicians with insights into patient condition that are early, actionable, and effective.

The RI identifies more patients at risk, and does so with fewer than half the false positives of NEWS and fewer than a third the false positives of MEWS.
