Many surveys have pointed out that the proportion of patients with various types of psychological disorders in the community is 4-8% of the population. The recently accepted report of the “Current Situation of Depressive Disorders and Related Services in Beijing”, led by Professor Cai Zhuoji, President of the Chinese Mental Health Association, points out that the lifetime prevalence of depressive disorders in Beijing community residents is 6.87%, and the prevalence of >60 years old is 8.18%. In the Epidemiological Survey of Anxiety Disorders in Baoding, the lifetime prevalence of anxiety disorders in local residents was 4.52%, and in the Epidemiological Survey of Anxiety Disorders in Urban and Rural Residents of Liaoning Province, Li Ning et al. pointed out that the lifetime prevalence of anxiety disorders reached 7.21%. In April 2005, the Chinese Medical Association found in an interview and analysis of 2,400 patients attending tertiary general hospitals in Beijing, Shanghai, Guangzhou, and Chengdu that depression and anxiety symptoms were prevalent in neurology, cardiovascular medicine, and gastroenterology patients, with an incidence of up to 25%. depression and anxiety, especially in patients with Parkinson’s disease, stroke, coronary heart disease, functional dyspepsia, postpartum, and menopausal syndrome have a higher percentage of depression/anxiety than other patients, but the undiagnosed rate is higher than 90%; only 1/6 patients with depression/anxiety are treated accordingly; Chen Jigen et al. pointed out that 20.84% of elderly people in the community have depressive disorders, so many scholars believe that the Therefore, many scholars believe that there is no great difference between the prevalence of anxiety and depression in the general population or community in China and some western countries, while the diagnosis and treatment rates are even lower. Patients attending community hospitals in China are predominantly middle-aged and elderly people with some common and chronic diseases, such as hypertension, coronary heart disease, diabetes, post-stroke, post-infarction, tumor, Parkinson’s disease and other disease patients. These populations are the high prevalence of anxiety-depression disorders. The causes of anxiety and depression in these patients are complex, including the disease itself, such as the damage to brain function caused by stroke, and social and psychological factors, such as the impairment of social function due to physical disability caused by the disease, the large amount of medical expenses, the psychosomatic torture caused by the disease, the worry and concern about the recurrence of the disease, the excessive fear of the Ministry due to the lack of understanding of the disease, and the weakening of social support factors due to long-term illness. Anxiety and depression are induced by the weakening of social support factors, and the social, psychological and physical relationships are further complicated by the depressed and unstable moods and further impairment of family and social roles caused by anxiety and depression. Secondly, patients with anxiety and depression also have many somatization symptoms, such as chest tightness, dizziness, headache, palpitations, shortness of breath, insomnia, weakness, and numbness of the limbs, etc. These symptoms are often not specific and are one of the symptoms of many cardiovascular diseases, so they are often the reason why many patients come to the clinic, and many clinicians, especially community doctors, have difficulty identifying them, and it is difficult to distinguish them from the patients’ original diseases. It is difficult for many clinicians, especially those in the community, to recognize it and differentiate it from the patient’s existing disease. The examination and treatment around these symptoms often consume a lot of time and energy of both doctors and patients and take up a lot of valuable medical resources, and the results are often unsuccessful and even aggravate the anxiety and depression. If the anxiety and depression symptoms are not detected, treated, and intertwined with existing chronic diseases, they become long-term, chronic, and complicated, resulting in deterioration of patients’ quality of life, loss of well-being, impairment of social functions, long term recovery from the disease, and a continuous increase in medical expenses. According to WHO, the total social burden of depressive disorders will rise to the second place after cardiovascular diseases by 2020, which should attract attention and consideration of countermeasures. In this regard, to cut off this vicious circle, it is necessary to identify and analyze the anxiety and depression symptoms early and identify them from the original disease. Of course, the presence of anxiety or depressive symptoms in these patients does not necessarily mean that they can be diagnosed as anxiety or depression, because according to the diagnostic criteria of our country or international psychiatry, these anxiety and depression, which are often caused or induced by physical diseases and cannot be explained by the primary disease, can be called anxiety or depressive states. However, the emergence of these anxiety and depression symptoms should still be actively intervened and try to improve or eliminate them, otherwise if they are allowed to develop, not only will the patient’s pain not be relieved at all, but the treatment of the disease itself will also bring difficulties and will increase unnecessary medical expenses, and in the long run these patients may also eventually develop into anxiety depression.
