Objective To investigate the spectrum of diseases and the current situation of antibiotic use in rural hospitals and community health service centers in Chengdu, so as to provide evidence for selecting essential medicines and promoting rational use of antibiotics. Method We selected 7 township/community health institutions, from which we collected inpatient and outpatient information. Information about antibiotic use was also collected, including categories, cost, and dosage. A standard questionnaire was used to investigate physicians’ prescription behavior for principal diseases. Result Urban and rural areas had different spectrums of diseases. The major diseases in urban areas included diabetes mellitus, hypertension, chronic obstructive pulmonary disease, and respiratory tract infection; while those in rural areas were infectious diseases of the respiratory system, digestive system, and urinary system. The physicians’ prescription behavior was mainly based on their personal experience. Antibiotics accounted for 30-50% of the total medicine cost. The top four types of antibiotics with the highest cost were cephalosporins, penicillin, quinolones, and macrolides. Conclusion Based on the different spectrums of diseases, essential drug lists and standard treatment guidelines appropriate for rural health care should be developed to improve the rational use of drugs. Factors such as the average cost of daily dose and the course of treatment should be taken into consideration to reduce the overall cost of medicine. An antimicrobial resistance monitoring system and special training courses on rational use of antibiotics should be utilized in the rural health institutions.

Objective To comparatively analyze the rationality of emergency medication after Wenchuan earthquake with that after Lushan earthquake in West China Hospital of Sichuan University, based on the use of medicine of the victim’s disease spectrum. Method By using Excel, defined daily dose system (DDDs) and drug utilization index (DUI) were used as the evaluation indexes to analyze the rationality of emergency medication in West China Hospital of Sichuan University within one month after Wenchuan earthquake and Lushan earthquake. Results Within one month after Wenchuan and Lushan earthquake, there were 1 839 and 488 victims treated in the hospital, respectively. Within one month after the two earthquakes, the variation tendency of DDDs of drugs and number of victims was consistent, and the consistency was better in Lushan earthquake than that in Wenchuan earthquake. Among the 60 drugs which DDDs were ranked top five in their pharmacological class (top ten for antimicrobials) in Wenchuan earthquake, the majority of them were injections (injections vs. non-injections: 70.0% vs. 30.0%); the results showed that the medication (DUI=1) only accounted for 10.0%, the medication (DUI<1) accounted for 28.3%, which implied that the use of drugs was insufficient, the medication (DUI>1) accounted for 61.7%, which implied that drugs were overused; the average of DUI was 1.61. And in Lushan earthquake, injections also accounted for a larger proportion than non-injections (63.3%vs. 36.7%); the results showed that the medication (DUI=1) accounted for 15.0%, the medication (DUI<1) accounted for 38.3%, the medication (DUI>1) accounted for 46.7%; the average of DUI was 1.30. Conclusions Base on the DUI, we draw the conclusion that the rationality of emergency drug use and the timeliness of emergency drug supply were better in Lushan earthquake than those in Wenchuan earthquake. But the rationality of using the DUI, which is an evaluation index for normal conditions, to evaluate the emergency conditions still needs to be further verified.
ObjectiveTo investigate and analyze the antibiotic use in Sichuan Province. MethodsAntibiotic use of inpatients was investigated in 23 hospitals on the day of June 25, 2011. ResultsThe percentage of antibiotic use was 42.4% in the total 27 144 inpatients, the range of which was between 24.3% and 63.3% for each hospital. And 63.8% of the antibiotic use was for therapeutic purpose, and 72.2% used only one antibiotic drug. A total of 36.9% of the patients receiving antibiotic treatment for therapeutic use sent samples for pathogenic detection. With the increase of the size of the hospital (judged by the number of beds), antimicrobial drug utilization decreased with statistical significance (χ2=411.834, P=0.000). With the improvement of regional economic level (judged by per-capita GDP of each region), the hospital antimicrobial usage decreased with statistical significance (χ2=500.093, P=0.000). The three types of antimicrobial drug most frequently used were other β-lactam antibiotics, penicillin and third generation cephalosporin. ConclusionAntibiotic use is reasonable in Sichuan Province as a whole. However, it is necessary to reduce irrational use of antimicrobial agents continuously, and to strengthen the management of clinical antibiotic usage among inpatients.
ObjectiveTo analyze the clinical distribution and changes of antimicrobial resistance profiles of Staphylococcus aureus (SA), as well as to provide the basis for the prevention and treatment of infection. MethodsThe clinical data and the antimicrobial resistance profiles of SA were collected from Jan, 2008 to Dec, 2014 in West China Hospital of Sichuan University. The WHONET 5.5 software was used to analyze the resistance data. ResultsA total of 5 698 SA isolates were included within 7 years. Of all strains, 2 721 (47.8%) were isolated from secretion, 1 638 (28.75%) were from respiratory tract specimens, 451 (7.9%) were from pus, and 362 (6.4%) were from blood. 811 (49.5%) SA isolates from respiratory tract specimens were Methicillin-resistant Staphylococcus aureus (MRSA), which was higher than those from secretion, pus and blood. 1052 (18.5%) SA strains were isolated from the dermatological department, 604 (10.6%) were from the orthopedics department, 472 (8.3%) were from the intensive care unit (ICU), 471 (8.3%) were from the department of burn, and the detection rate of MRSA from ICU (341, 72.2%) was the highest. During last 7 years, the total separation rate of SA was 8.2%, among them 1 858 (32.6%) MRSA were isolated, and the detection rate was 32.6%. The resistant rate of SA to erythromycin, clindamycin, tetracycline, gentamicin, rifampin, ciprofloxacin, levofloxacin and moxifloxacin had a statistically significant decrease from 2008 to 2014, while the resistant rate of SA to trimethoprim/sulfamethoxazole had increased. No vancomycin, linezolid, teicoplanin or tigecycline resistant strain was detected. The resistance rates of MRSA to common antibiotics such as penicillin G, erythromycin, clindamycin, tetracycline, gentamicin, rifampin and fluoroquinolones were higher than those of MSSA, while the resistance rate of MRSA to trimethoprim/sulfamethoxazole was lower than MSSA. ConclusionCompared with the monitoring data in China, the drug resistance of SA in West China Hospital is well controlled. However, experience-directed antibiotic treatment of MRSA infection is still limited. MRSA infection remains a serious problem in critically ill patients. The rational use of antibiotics and application of effective infection control measures are important to decrease the MRSA infection.
Objective Inappropriate drug dosage is a serious problem in pediatrics, mainly due to the lack of clinical evidence in children, suitable preparation formulation, and standardized methods for dose adjustment. A method for evaluating and monitoring appropriate dosage in pediatrics is urgently needed. The drug utilization index (DUI) based on the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) has been widely used in the assessment of appropriate dosage in adults. We explored possible methods for assessing appropriate dosage in children. Methods Based on our previous studies, we discuss cDUI in the assessment of appropriate dosage in children as follows: the meaning of cDDD, the establishment of a standardized system, and the classified evaluation of dosage in pediatrics. Results Although the definition of cDDD draws on the concept of defined daily dose (DDD), the meaning of cDDD is different from that of the latter. Specifically, the purpose of cDDD is to evaluate appropriate pediatric dose, while DDD is a unit of measurement. cDDD could be used to assess dose rationality for common and serious pediatric diseases, and would be refined over time. A single cDDD should be assigned per drug and indication and given per drug and route of administration. The influence of age, weight, diagnosis, and administration route on the dosage should be considered. Classified evaluation should be used and weight should be given to the above mentioned factors in order to evaluate the appropriate dose objectively and comprehensively. Conclusion Dosage regulation in pediatrics has an important role in improving medical quality and protecting the safety, effectiveness, and economy of medical therapy in children. The establishment of a cDUI system is a good try in pediatric dosage evaluation. Although there are still defects within this proposed system and methodology, the principle seems feasible.
ObjectiveTo probe into the writing quality and rational use of drugs for Emergency Department prescriptions in West China Hospital of Sichuan University. MethodsFrom January 2012 to December 2013, the prescriptions for emergencies were selected randomly. According to prescription management method and standard management of hospital prescription comment requirement, the quality of prescription was analyzed. ResultsFrom 2012 to 2013, the qualified prescription rate increased from 91.45% to 96.70%. The average number of drugs on each prescription was 1 or 2; the utilization rate of antibacterials was below 20.00%; the utilization rate of essential drugs increased from 60.68% to 66.15%; the utilization rate of generic drug name approached 100.00%. However, the utilization rate of injections increased from 82.92% to 85.67%. ConclusionBy prescription reviews, we have listed the problems, and intervened irrational prescription to improve the rate of qualified prescriptions. The high rate of injection utilization is a warning for us to take more effective, more specific and stricter intervention measures.
