Hospital-acquired infections are infections that occur in all populations in medical institutions, including those acquired by patients, chaperones and medical staff in hospitals. A survey in the 1980s found that the incidence of hospital-acquired infections was as high as 8.4% – 9.7%, with teaching hospitals and tertiary general hospitals being the highest. Hospital infections not only prolong patients’ hospitalization, increase pain and economic burden, but also can directly or indirectly lead to patient death, China’s survey shows that hospital infections prolong patients’ hospitalization for 10.37-20.57 days, and the United States estimates that 75,000-150000 people die from hospital infections every year. Now due to the abuse of antibacterial drugs and a variety of invasive diagnostic techniques widely carried out, especially the increase in the number of immunodeficient patients or the use of immunosuppressive drugs, the incidence of hospital infections is climbing, the severity of the disease can not be estimated, the past two years a number of neonatal infections in hospitals and the outbreak of hepatitis C after hemodialysis is a high warning that we must pay attention to the prevention of hospital infection! Why do hospital infections occur? This is related to the characteristics of the hospital population itself and the special environment of the hospital! First of all, the physical condition of patients in hospitals is poor, most patients suffer from chronic underlying diseases, immune deficiency, vulnerable to a variety of pathogens; and the high development of modern medicine, the frequent use of invasive treatment technology, although saving the lives of many patients, but inevitably also increased the chances of patients infected with other pathogens; especially tumors, autoimmune diseases, immune deficiency or deficiencies, etc. Diseases and other patients not only long hospitalization, but also often use immunosuppressants and other drugs, the ability to resist pathogens is weaker, especially prone to hospital infections; antibacterial drugs are a double-edged sword, properly used to cure the disease, but improper use will lead to additional hospital infections; if they are suffering from infectious diseases and treatment in general hospitals, more infectious to other patients and medical staff, artificially increasing the The occurrence of hospital-acquired infections! Secondly, the special environment of the hospital is also prone to hospital infections: hospital patients, highly dense crowd, a variety of pathogens are relatively concentrated; if the hospital building design process is not very reasonable, ventilation and lighting is not good, the environment is crowded, also prone to hospital infections, the SARS outbreak in 2003, China’s most famous hospital is because of the hospital design, ventilation is not good and caused serious hospital infections, when the dean The face of the people of the country shed tears of both guilt, but also helpless! More is a great warning: hospital infection is very terrible! Must be actively prevented! How to prevent hospital infections? 1, strengthen physical exercise, timely vaccination of various vaccines, improve the living environment to avoid or reduce illness. 2, once you feel unwell, must go to the regular medical institutions for timely treatment, the best choice of beautiful environment, fresh air, good ventilation, spacious hospital to seek medical treatment! 3, if suffering from viral hepatitis, tuberculosis, measles, chickenpox and other infectious diseases must be treated in infectious disease specialist hospitals, because infectious disease specialist hospitals can make patients recover quickly, short hospitalization time, more scientific and effective measures to prevent hospital infections, and hospitalization environment as a garden, fresh air, oxygen, sunlight, ward process design is reasonable, better ventilation, to avoid cross-infection between personnel, at present has No hospital infection has occurred, so it is beneficial to patients, escorts, medical staff and society! 4, reasonable treatment: in the hospital must work closely with medical staff, choose the appropriate treatment methods, so as to not only treat the disease, but also minimize or avoid hospital infections, especially in the use of antibacterial, immunosuppressive drugs should be repeatedly deliberate! Avoid curing the original disease, and infected with other bacteria, viruses, fungi and other annoying pathogens! 5, hospitals to strengthen the prevention and treatment of hospital infections: medical staff to strictly enforce the standard prevention, good disinfection of the hospital environment, strengthen ward ventilation, standardized procurement and disinfection of medical equipment use, rational use of antibacterial drugs, especially to do a good job of medical staff hand disinfection and prevention of disease transmission through blood, through equipment; once the hospital infection must do a good job of disinfection and isolation, reporting, treatment work, particularly serious hospital Infections should even be stopped after the occurrence of patients!
