There are often hidden “killers” in general hospitals, and these killers are the “psychological disorders” hidden in general hospitals. They are hidden because they change their faces and manifest themselves in various forms of physical symptoms in various departments, and they are killers because they are indeed very harmful to patients and extremely wasteful of medical resources. Faced with these “killers”, many doctors are at their wits’ end. On the one hand, these “killers” are difficult to identify, non-psychiatric or psychological doctors do not know how to diagnose and identify and deal with them, and improper handling can lead to medical disputes, so that both patients and doctors are hurt. The most important thing is to uncover the true nature of these killers. Some data show that 21%-26% of internal medicine outpatients have psychological problems, the prevalence of psychological disorders in patients with chronic somatic diseases is 25%, in patients without somatic diseases is 17.5%, the lifetime prevalence of patients with chronic somatic diseases reaches 42% (mostly substance abuse, emotional or anxiety disorders), in patients without chronic somatic diseases is 33.4%, 33 -60% of short-course general medical-surgical patients have significant psychosocial factors and psychological disorders. First let’s look at the more common “killers” around us: depressive disorders Depression is a state of mind, is characterized by a significant depression, loss of interest or pleasure in activities that are usually enjoyable. The most common symptoms are: 1. significant depressed mood; 2. loss of interest or pleasure; 3. decreased self-confidence or low self-esteem; 4. feeling worthless and guilty; 5. feeling a bleak future; 6. self-injurious or suicidal thoughts or behaviors; 7. sleep disorders; 8. eating disorders; 9. decreased libido; 10. decreased energy, easy fatigue, and reduced activity; 11. difficulty or decreased concentration. Such patients are often found in departments other than psychology, such as cardiovascular medicine, gastroenterology, neurology, oncology …… and, in particular, the rate of depression in patients with chronic somatic diseases is very high, such as acute heart attack 25%, diabetes mellitus 27%, stroke 23%, coronary heart disease 27%, cancer 42 Many patients often neglect their mental health, only emphasize their physical symptoms, or are unwilling to admit or conceal their depressed mood, making it difficult for non-psychiatrists to detect, and patients’ families do not pay enough attention to it, and will think that the patient’s depressed mood performance caused by physical illness is It is more normal and the treatment of physical illness is the most important. However, from a psychological point of view, depression is potentially very harmful, from having a negative impact on one’s physical condition, life, work and social life to committing suicide, which ranks among the top three diseases causing the highest percentage of deaths. Depression in general hospitals is often insidious, perhaps mild but persistent, and causes a lot of suffering to both the person and the family. It is a disorder that needs to be treated and is treatable; the key is early detection. Although insidious, we can still detect the problem in general by asking some simple questions to uncover the “killer”. We can ask: 1. Do you feel depressed, depressed, and pessimistic about your future every day; 2. Are you uninterested in things that usually interest you; 3. If these states (lasting more than two weeks), you should consider whether you are in a state of depression, and consider whether to carry out drug intervention or psychological guidance treatment. These four sentences are a relatively simple and easy to grasp way to identify the “killer”, which summarizes the core symptoms of the diagnostic criteria for depression, as reflected in a large scale survey of 1884 patients in six European countries (Belgium, France, Germany, the Netherlands, Spain and the UK), so depression is not scary, what is scary is What is scary is that it is not detected, so that this “killer” becomes a big pest in the treatment of patients and a stumbling block for doctors of various disciplines. If everyone is more vigilant and raises mental health awareness, the world of psychology will become a beautiful place, so let’s uncover the psychological “killers” hidden in general hospitals.
