In CRICO Strategies' 2016 study, they found that there are often communication breakdowns among medical professionals, as well as between medical professionals and patients. Which of these numbers reflect what they found from 2009-2013 in the Harvard hospitals they studied? Healthcare miscommunication was a factor in between one-fourth and one-third of all medical malpractice claims. It cost the hospital system $1.7 million. Less than one-third of very severe cases involving injury (as opposed to disease) involved failures in communication. There were less than 1,500 deaths.
