Auntie Dong’s father was hospitalized again. After his condition improved, he was afraid to leave the hospital because he was afraid to go home and get a fever again, so he stayed in our department for a long time, and he also had frequent lung infections during his hospitalization. Why do patients get infections even when they are hospitalized? Many families think that hospitals are safe-havens. In fact, during hospitalization, there will be hospital-acquired infections, infections with very strong pathogenic bacteria, this infection is more difficult to control and aggravated by one attack, many patients will soon become life-threatening, because: 1. strong pathogenic bacteria, 2. extensive drug resistance bacteria, we have heard of drug-resistant bacteria or super drug-resistant bacteria, right? Later, we repeatedly persuaded my aunt to take my father out of the hospital before going back. Grandpa came home in good shape and was able to walk with support and put on weight. But two days ago, he was hospitalized again because of fever. The infection at home is usually a very low pathogenic bacteria, timely hospitalization can be controlled quickly, grandpa’s temperature was normalized on the same day, but during the hospitalization again because of the infection of gram-positive bacteria and fever again, after another anti-coccus treatment finally improved, and as soon as possible to avoid re-infection. Now Auntie Dong has the experience to know that patients will have recurrent lung infections in the hospital for a long period of time, so she rushes home when her condition is cured, and if fever or other discomfort occurs at home she immediately contacts our department, and we have established a very good relationship of continuity and coordination of medical services. Comprehensive, continuous and coordinated For elderly patients with poor physical condition, we just need to remember 2 points: 1. If you find any uncomfortable symptoms such as weakness, depression, fever, confused speech, poor appetite, etc., you need to go to the hospital or be hospitalized in time. 2. If the symptoms are relieved during hospitalization, you must be discharged as soon as possible to avoid hospital-acquired infections. Elderly people are prone to the following characteristics because of the decline in the function of various organs of the body, the compensatory capacity, reserve capacity and immunity of the body declines with age: 1. 2. Incognito onset. 3. Rapid onset and short duration of illness, and easy to develop consciousness disorders. 3. Prone to water and electrolyte disorders. 4. Prone to multiple organ failure. 5. Prone to sequelae and complications. 6. High incidence of malignant tumors. This explains why some elderly people are fine one day and die the next. This situation is common in clinical practice and requires all family members of elderly patients to be fully aware of the above characteristics, to identify the problem as soon as possible and send them to the hospital as soon as possible. For example, if your parent suddenly develops hallucinations and hallucinations for no apparent reason, it is possible that there is an insidious condition in the body, rather than a psychiatric illness, which is often treated as a psychiatric illness, causing further aggravation. It may be pneumonia in the elderly, but pneumonia in the elderly does not always present with fever, elevated blood levels, etc. and is often missed. Therefore, elderly people, especially the elderly, should pay close attention to any abnormalities and seek medical attention as soon as possible.
