Their patients had a low ED utilization rate over a twelve-month period. The metrics were adjusted for severity of illness represented by the physicians RAF/HCC score.

Research by the Centers for Disease Control shows more than 21 million Americans over 65 visit the Emergency Department (ED) annually -- an increase of more than four million from a decade ago. In Hawaii, seniors are using the ED in record numbers.  In fact, a study of Hawaiian primary care physicians (PCPs) showed 53% had patient ED utilization rates exceeding the national average

According to a recent study, hospitalization can be debilitating to seniors, and can often prevent them from living independent lives. Additional studies show the majority of emergency room visits are “potentially preventable.”

Because of this, MDX Hawai’i, a network of healthcare providers that serves over 28,000 Medicare Advantage recipients, is recognizing physicians who keep patients healthy and out of the ED.

Throughout 2018, more than 100 physicians will receive MDX Hawai`i Excellence in Kupuna Care awards based on a list of quality metrics. In addition, MDX Hawai`i will offer a series of continuing medical education (CME) webinars to review best practices and offer testimonials from top-performing physicians.
