Serious illness early warning and household verification are usually implemented through government health departments and community health service centers. They will select specific groups for screening according to a series of screening indicators and policy requirements. These people are usually at high risk of some major diseases, such as hypertension, diabetes, tuberculosis and so on.
During the verification process, medical staff will visit patients at home to find out their health status, medical history and whether they have received corresponding treatment. They will also provide relevant health education, disease management advice and medical services to promote early detection and treatment of diseases.
In a word, the purpose of early warning and door-to-door inspection of serious illness is to screen and intervene the seriously ill people in advance, so as to implement early intervention and treatment and prevent the deterioration and spread of the disease.
