Coping with loss of hospital, rural town realizes: We don’t need a hospital
Two studies -- published in 2013 and 2019 -- brought into question the effectiveness of UBT, but a paper published today in the American Journal of Obstetrics and Gynecology "really puts a nail in that coffin," according to principal investigator Thomas Burke, MD, FACEP, FRSM, director of the Global Health Innovation Lab in the Emergency Department at Massachusetts General Hospital and an associate professor at Harvard Medical School and the Harvard T.H. Chan School of Public Health.
The reason we undertook this study is that those two trials caused a great deal of confusion and controversy regarding UBT. We decided to take an extremely rigorous approach, bringing together all of the world's literature on this technique and inviting independent investigators to join. It was a massive project." Thomas Burke, principal investigator
Burke and his colleagues conducted a systematic review and meta-analysis of 91 randomized control trials, nonrandomized studies, and case series, and found an overall success rate of 85.9 percent for UBT.
"So what this really teaches us is that the challenges experienced in these two trials were about the program implementation, not the device itself," he said. "There's no question the device works fine. But saving a life is much more complex than just handing someone a device that's new to their practice. We need to study how to integrate the device into a health system so that good uptake, appropriate use, and best practice result in quality care."
Burke pointed out that it is "exquisitely clear" that in many areas of the world, maternal mortality drops significantly when UBT is used. "They have saved many lives," he said. "But there are still places where one in six women lose their lives from pregnancy-related causes and in 2020 that should never be. It's an embarrassment to humankind." Source:
