Situation: A survey on the health of Thai people based on their medical checkup found that some people did not realize they were ill. More than one-third of diabetes patients did not know that they had the illness and more than half of people with hypertension had never been diagnosed with the condition. Some groups of people were unaware of the importance of medical checkups and did not have a necessary medical checkup. Meanwhile, some groups of people who live in urban areas and have access to such services have medical checkups that are more than necessary and unreasonable. This results partly from their long-standing familiarity with medical checkups. Besides, there is not an organization that manages to set the list of necessary medical checkups, examine and control the standard of medical checkups and inform people of rapidly changing medical technologies. Most medical checkups emphasize laboratory tests, many of which lack information to support their effectiveness and efficiency and may have negative impacts on the people who are initially diagnosed with some illnesses, based on such tests, although actually they are not ill. This means a waste, exposes diagnosed people to unnecessary treatment or additional medical checkups and causes concerns. Meanwhile, the people who are diagnosed with no illness can be neglectful and fail to control their risk factors. This may result from the facts that they are not ill or have some hidden illnesses that are not detected through medical checkups due to some flaws of technologies applied for medical checkups.
