For 30 years, hospitals, insurers and other healthcare providers have sought ways to track patient outcomes to better determine which medical procedures are most effective and which physicians need to show improvement or be weeded out.

Until now, that ability has largely eluded them. But now, Beverly Grove-based OutcomeMD Inc. is one of a small group of health tech startups aiming to deliver that holy grail of healthcare metrics. OutcomeMD has developed a software platform that interacts with patients and tracks their symptoms before and after they undergo medical procedures.

In the two years since officially launching the platform, OutcomeMD has been tracking patient symptoms and outcomes for health insurers, hospitals, surgery centers, individual doctor practices and organizations such as the Veterans Affairs Greater Los Angeles Health Care System.
