Objective To analyze the rationality of emergency medication in the West China Hospital after Lushan earthquake based on the actual drug use of earthquake victims. Methods We applied DDDs and DUI as evaluation index, input data using Excel software, and analyzed if the emergency medication was required for the injury/illness and the rationality of emergency medication. Results Earthquake victims mainly had trauma and wound infection and they were given antibiotics as main treatment one week after the earthquake. Drugs for the respiratory system and digestive system were mainly used in patients who mainly manifested as non-traumatic diseases and internal diseases four weeks after the earthquake. Among 49 kinds of drugs which could be calculated for the value of DUI, injection accounted for a larger proportion than non-injection (59.18% vs. 40.82%). The results showed that, the medication (DUI=1) only accounted for 12.24%; the medication (DUIlt;1, Mean=0.65) accounted for 38.78%, which implied insufficient drug use; the medication (DUIgt;1, Mean=1.77) accounted for 46.94%, which implied drug overuse. Conclusion Medication for every system is basically timely and rational when treating symptoms and causes in the West China Hospital within one month after Lushan earthquake. However, the rationality of emergency medications using DUI=1 under normal conditions still needs to be further verified.
Objective To analyze drug use for 23 sick and wounded hospitalized in the departments of gynaecology, obstetrics and paediatrics in the West China Second University Hospital, during one month after Lushan earthquake, so as to provide references for the drug use for the sick and wounded women and children. Methods Medication information was retrospectively investigated in the departments of gynaecology, obstetrics and paediatrics in the West China Second University Hospital during one month after Lushan earthquake. We extracted data including hospitalization duration, medication prescriptions, types and costs of essential medicines, types and costs of antibiotic medicines using the HIS system. Discharge diagnosis was standardized and classified according to ICD-10. Indicators of rational drug use included defined daily dose (DDD), defined daily dose statistic (DDDs), drug utilization index (DUI), children defined daily dose (cDDD), children drug utilization index (cDUI), proportion of essential medicines, proportion of antibiotic medicines, mismatch of medicine and diagnosis, repeated drug use, improper combination of drug, incorrect usage and dosage, and frequently drug change. Medication information was evaluated and discussed by the prescription working group. Discrepency was resolved by consulting with the panel. Results A total of 23 sick and wounded women and children were assessed during one month after Lushan Earthquake. There were 13 sick and wounded children in the department of pediatrics (mainly manifested as bronchial pneumonia) and 10 sick and wounded women in the department of gynaecology and obstetrics (mainly involved in cesarean delivery). Proportions of essential medicines were 13/13 in the department of pediatrics and 9/10 in the department of gynaecology and obstetrics. Proportions of antibiotic medicines were 10/13 in the department of pediatrics and 8/10 in the department of gynaecology and obstetrics. Irrational drug use was mainly caused by improper use of antibiotics. Conclusion The drug use for 23 hospitalized sick and wounded is rational in the departments of gynaecology, obstetrics and paediatrics in the West China Second University Hospital during one month after Lushan earthquake. Evaluation methods of rational drug use in high-risk population are urgently needed. Using cDDD and cDUI is an active exploration for the evaluation of pediatric drug use, which needs more practice to test and improve.
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.

Methods The medical records of 265 patients who underwent the surgeries from January to December 2009 were randomly extracted, and the medication rationality was evaluated according to "Guiding Principles of Clinical Use of Antibiotics" and "Notice of Medical Department Office about Antibiotics Clinical practice Management Related Questions". Results All of the 265 perioperative patients were treated with antimicrobial drugs with a utilization rate of 100.00%, and the unreasonable rate of perioperative prophylactic use of antimicrobial agents was 63.89%. The main reasons included over-extended medication indications, high starting points, inappropriate time points of prophylactic medication, long duration of prophylactic medication and unreasonable drug combination. Conclusion The perioperative prophylactic use of antimicrobial agents is clinically unreasonable. It is necessary to carry out training on the rational use of antimicrobial agents to enhance the management of antimicrobial drug use and regulate the use of antimicrobial agents in perioperation.

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.
Objective To investigate the awareness of rational use of drug (RUD) on medical workers in hospitals of different ranks, the establishment and execution of relevant strategies in hospitals of different ranks, and the main factors affecting RUD on medical workers, so as to provide references for the generalization of RUD. Methods A certain number of different ranks of hospitals in Chengdu and Zigong were randomly selected by the convenience sample method. Medical workers in each hospital were selected through face-to-face interviews with a self-designed questionnaire. Monte Carlo Chi-square analysis was applied on the hospital ranks and formulation of RUD guidelines, and logistic regression analysis was performed on the awareness of RUD knowledge of the respondents. Results Among 700 questionnaires distributed, 672 were retrieved (response rate 96.0%). The numbers of respondents who were familiar with the Pharmaceutical Affairs Councils (PACs) as well as the Pharmacy and Therapeutics Committees (PTCs) were 217 (32.29%) and 83 (12.35%), respectively. The number of respondents who understood the concept of essential medicine was 502 (74.71%). A total of 441 (61.16%) medical workers had been trained on RUD, 199 (29.61%) medical workers denied there were PTCs in their hospitals, and 60.71% of the medical workers mentioned that the use of drug was monitored and controlled with the feedback in their hospitals. The result of logistic regression analysis indicated that the professional title (P=0.038), awareness of essential medicine (Plt;0.001) and participation of RUD training (P=0.008) were the factors influencing the awareness of RUD. Conclusion Both management and education should be executed at the same time to elevate the level of rational use of drug. In order to increase the level of RUD we should complete monitoring institution and improving RUD awareness of workers. Additionally enhancing the rationality of medication should be performed by establishing guidelines of treatment or medication. Improving personal knowledge, scientific information and medication custom should be performed by standardizing regulations, strengthening management, emphasizing education and promoting communication between doctors and patients.
