Most people will experience at least one wrong medical diagnosis in their lifetime, resulting in health problems, psychological suffering and financial cost, according to a new report. Because diagnostic errors are generally discovered in retrospect(回顾), researchers said more work needs to be done to improve medical teams and find ways to avoid errors that can change people’s life in the distant future.

“Diagnosis is a collective effort that often involves a team of health care professionals---from primary care physicians to nurses.” said John Ball, chair of the committee which wrote the report. “The type of a single physician observing a patient case and deciding a diagnosis is not always accurate, and a diagnostic errors, we have to look more broadly at the entire process of how a diagnosis is made.”

The researcher, said there are not enough data on diagnostic errors, and efforts to improve diagnosis and reduce errors have not been frequent. The medical culture discourages transparency and makes it more difficult to correct them. The blame lies in cooperation and communication between members of medical teams treating patients, patients themselves, and their families. Besides this, researchers found the healthcare system is not designed for the collaboration needed in the diagnostic process and that diagnosis will continue to worsen if new ideas are not put forward.

The committee recommended more information, from electronic health records to test results, be made more easily available to families and caregivers, to help them better learn and understand what is going on with their health. Creating an environment for patients to question a diagnosis or add information about their condition could also help better influence diagnosis.

Most significantly, the researchers said methods need to be established to make communication between doctors and patients easier. Doctors are not encouraged or paid to communicate with patients as much as they should be.
