RESUMEN
Objective To approach the strategies of prevention and treatment of elderly patients with diabetic foot by analyzing the common pathogens and their drug- resistance.Methods136 isolated strains of drug resistance pathogens from 68 elderly patients with infected diabetic foot were retrospectively studied in our hospital from January 2008 to June 2010.Results Bacterial pathogens and fungal pathogens accounted for 92.6％ and 7.4 ％,respectively.The bacterial pathogens included gram-positive bacteria (58.7％) and gram-negative bacilli (41.3％).Among the gram-positive bacteria,staph were most common.Furthermore,the incidence of methicillin resistant staphylococcus aureus (MRSA) and methicillin resistant coagulase negative staphylococcus (MRCNS) increased year by year.Vancomycin-resistant gram-positive bacteria did not appear.Among the gram-negative bacilli,enterobacteriaceae were the most common pathogens.Patients with mixed infections accounted for 61.8％.Fungous infections were all in the form of mixed infection,increasing with years.Conclusions Pathogenic bacteria and its drug resistance should be timely monitored to control and prevent the diabetic foot in the elderly patients.
RESUMEN
Objective To study the causes, epidemiology and control measures of outbreak of MRSA nosocomial infections. Methods The epidemiologic survey was carried out for 7 cases infected with MRSA within short term in the department of neurosurgery. The risk factors and epidemiological trends was analyzed. Results Some measures, such as strengthening training of health worker with MRSA prevention and control knowledge, enhancing their awareness of infection prevention and control, and controlling patients infected with MRSA effectively using warning mechanisms of MRSA infection outbreaks, should be taken to control the outbreak and spread of MRSA promptly. Conclusions Nosocomial MRSA infection is preventable and controllable.
RESUMEN
Objective To judge the hospital crisis and to provide the approaches and strategies to avoid the hospital crisis. Methods To conduct specific diagnosis of important risk factors of hospitals using expert diagnostics and crisis identification. Results Combined with the index system and weight affecting public hospitals' crisis, to focus on preventing risk factors directly, which had severe affection and put great weight on hospital crisis. To raise up the containments, managing strategies and mechanisms for public hospitals' crisis. Conclusions It is an effective method to warn and prevent hospital crisis by the way of establishing public hospital crisis value with fuzzy comprehensive evaluation system.
RESUMEN
OBJECTIVE To improve the compliance of medical institutions in the prevention and treatment of influenza A(H1N1) by introduction of game theory.METHODS Solving the mixed strategy Nash equilibrium with the application of game theory model.RESULTS There was inevitable relationship between the proportion of inspections,amercement amount and compliance of prevention and treatment.CONCLUSIONS If the health administration departments decrease the proportion of inspection,the probability will be reduced on the attitude of the medical staff;If the health administration departments increase the proportion of inspection,the probability will also be increased.
