About 7.5 percent of immunity tests and 12.2 percent of biomedical tests provide inaccurate results, a survey has warned. The warning was released at the 2nd hospital quality forum themed “hospital safety” held in Ho Chi Minh City on Wednesday. At the event, the Center for Standardization and Quality Control in Medical Laboratories of HCMC announced the results of the latest survey on the quality of medical testing. Accordingly, besides inaccuracies found in immunity and biomedical tests, about 8.9 percent of hematological tests are also proven to be erroneous. The survey also shows that a high proportion of district hospitals and private testing centers are unqualified in terms of medical testing, said Tran Huu Tam, director of the center. Dr Maria Dung, a member of the medical program under the Germany-Vietnam cooperation project, said that there are many differences between the pathological conclusions made by doctors in central Thai Binh and Nghe An Provinces and those made by doctors at Bach Mai Hospital based on the same X-ray films of patients. The program has collected and reviewed 1,022 X-ray films of patients in the provinces and their related medical records, Dr Maria said. At the forum, Dr Nguyen Trong Khoa, deputy head of the Health Ministry’s Medical Examination and Treatment Management Department, said the ministry will issue a list of 83 quality criteria to hospitals, the first of its kind in Vietnam, with an aim to improve medical treatment quality.
