Objective To investigate drug usage and costs of pneumonia inpatients in Karamay Central Hospital in 2014 and to provide baseline for evidence-based pharmacy study of single disease in respiratory system. Methods The information of drug use and expenditure of pneumonia inpatients were collected from the hospital information system (HIS). We analyzed the data including frequency, proportion and cumulative proportion by Excel 2007 software. Results A total of 309 inpatients were included, among the 78.96% were more than 60 years old. Among the antibiotics single therapy, the frequency of cefoperazone and sulbactam was the highest. Among the antibiotics combination therapy, the frequency of β-lactam antibiotics was the highest. Conclusion Pneumonia inpatients in Karamay Central Hospital are mainly older patients. The β-lactam antibiotics is used most in clinical practice.
The current quantitative methods of bilirubin have disadvantages such as high cost and low sensitivity. Due to the negative correlation between the level of serum bilirubin and the risk of cardiovascular diseases, a fluorescent ratiometric film sensor was developed aiming at bilirubin detection at low level concentration. Blue-emitting and red-emitting gold nanoclusters were assembled into the same film using layer-by-layer self-assembly technology. Detection of bilirubin was achieved based on the intensity ratio of the two nanoclusters. Bilirubin exposure causes fluorescent quenching of the film. The fluorescence intensity ratio of the two cluster probes had quantitative relationship versus bilirubin concentration. Based on this film sensor, a portable fluorescence detection system was designed for the ratiometric sensing of bilirubin. The hardware of the system was mainly composed of main control chip STM32F407, TSL237 and TSL238T optical frequency sensor. A light-avoiding dark room and detection light path were designed through three-dimensional printing to reduce the interference from ambient light and improve detection accuracy. Experimental results showed that the proposed detection system had strong anti-interference, good stability and accuracy. The linear coefficient of bilirubin detected by this system was 0.987. The system presented good results in reproducible experiments and possessed a good linear relationship with the data obtained by standard spectrofluorometer. The portable system is expected to detect serum bilirubin at low levels.
The purpose of this paper is to discuss the evaluation standard of rationality of medical examination from different perspectives, so as to provide theoretical evidence for medical department to establish the evaluation standard of the rationality of medical examination. By researching the relevant literature in the field of rational medical examination and combing the existing research results, this paper discusses the evaluation criteria of the rationality of medical examination from four dimensions: technology, ethics, law, and health economy. The following four suggestions are proposed for the current status of medical examination: construct clinical pathway management to avoid excessive medical examination; establish the internal supervision and evaluation mechanism to improve the professional quality of medical staff; improve medical examination-related policies, laws, and regulations, carry out specialized legislation; apply diagnosis-related group payment method, control the cost of medical examination.
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.
Objective To explore the change of constitution in thyroid diseases of West China Hospital between 2000 and 2012， in order to provide clinical evidence. Methods Clinical data， including gender， age， and pathological diagnosis of patients with thyroid disease who underwent primary thyroid surgery in our hospital from 2000 to 2012 were collected retrospectively and analyzed statistically. Results A total of 9 642 patients were enrolled， including 1 893 male patients and 7 749 female patients. The ratio of male to female patients was 1 to 4.09. In male patients， the proportion of thyroid carcinoma were significantly higher than those of female group （P=0.02）；in male patients younger than 45 group， the proportion of thyroid carcinoma were significantly higher than those of female group （P＜0.01）. There was no statistical difference on the proportion between male and female patients older than 45 group （P=0.90）. Proportion of thyroid carcinoma， especially proportion of papillary thyroid carcinoma （PTC） increased in general. Proportion of Hashimoto thyroiditis （HT） increased in general too. HT with thyroid carcinoma accounted for an increasing proportion of all patients with HT. Proportion of nodular goiter （NG） increased at first and then declined. Proportion of thyroid adenoma （TA） decreased on the whole. Conclusions Proportion of thyroid carcinoma， especially proportion of PTC increase in recent years on the whole in patients underwent surgery. All these changes need to be given sufficient attention.
Objective To evaluate the rationality of drug treatment for cardiovascular diseases in aged people and the effects of evidence-based practice. Methods Descriptive study was conducted to compare the therapies for the patients suffering from cardiovascular diseases before and after evidence-based practice by investigating drug use during 1998-1999 (211 cases) and 2002-2003 (211 cases). Results Among antihypertensive drugs, the ACEIs and diuretics played a more important role than before. CCBs and ACEIs were still the most frequently used drugs, and drug combination was more common, comparing to that before evidence-based practice. Lipid lowering drugs and ACEIs were used more common in coronary heart disease. Quality of life of patients was more emphasized and combination use of anti-anxiety drugs was adopted. When treating heart failure, β-receptor blockers, aldadinc and ACEIs were more frequently used. Conclusions After evidence-based practice, drug use is much more based on evidence instead of experience and textbook. As a result, the rate of reaching ideal blood pressure is higher than before. The rate of rational drug use before and after evidence-based practice has increased from 42% to 78%, respectively.
ObjectiveTo evaluate the rationality of antibiotics use by analyzing the prescription reviewing results.MethodsThe review data of antibiotic prescriptions in Beijing Hospital was randomly selected from 2016 to 2019, from which unreasonable prescriptions and the antimicrobial agents were analyzed, and the use of antibiotics and unreasonable prescriptions annually were compared.ResultsThe evaluation of rational use of antibiotics involved 79 701 outpatient prescriptions from 2016 to 2019. There were 10 drugs in the top five irrational rates of outpatient antibiotics, primarily cephalosporin and quinolones, accounting for 50% and 30%, respectively. The primarily unreasonable problems were over prescription (common in gastroenterology and dermatology), unsuitable indications (common in otolaryngology), inappropriate usage and dosage (common in urology, dermatology and gastroenterology), and failure to write clinical diagnosis or incomplete clinical diagnosis (common in obstetrics and gynecology and general surgery). During the four years, the proportion of antibiotics prescriptions and the irrational rate decreased annually.ConclusionsThe use of antibiotics in outpatient department of Beijing Hospital has achieved initial results, however, there are still some problems. We should further strengthen the management of antibiotics usage, strengthen training and learning, and increase medical cooperation to promote rational drug use in clinic.
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 investigate drug usage and costs of chronic obstructive pulmonary disease (COPD) inpatients in Karamay Central Hospital in 2014 and to provide evidence and reference for evidence-based pharmacy study on COPD. Methods The information of drug use and expenditure of COPD inpatients were collected from the hospital information system (HIS). We analyzed the data including frequency, proportion and cumulative proportion by Excel 2007 software. Results A total of 194 inpatients with COPD/AECOPD were included in Karamay Central Hospital in 2014, the average age was 74.28±7.81 years old. Fifty-three drugs were used for COPD treatment; the total frequency were 1 798 times and per capita cost was 7 419.78 yuan. The top three used drugs were budesonide suspension, montelukast tablets and methylprednisolone injection. In total expenditure, the cost of piperacillin-tazobactam, imipenem/cilastatin and moxifloxacin injection ranked top three. Conclusion The top 3 used drugs are budesonide suspension, montelukast tablets and methylprednisolone injection for COPD inpatients in Karamay Central Hospital in 2014, while the top 3 total expenditure drugs are piperacillin-tazobactam, imipenem/cilastatin and moxifloxacin injection.
Objective The Chengdu initiative essential medicine policy is part of the Special Healthcare Program of Comprehensive Reform for Coordinated and Balanced Urban-rural Development. We aimed to investigate the current situation of medicine use in rural hospitals and community health service centers, so as to provide evidence for policy-makers to select essential medicines and facilitate rational use of medicines. Method We selected 7 township/community health institutions from which to collect medicine use information, including medicine category, number of medicine categories, cost and consumption. Descriptive analysis and the ABC classification method were applied for statistical analysis. Results The number of medicine categories used in the community health institutions was four times greater than that in the township health institutions. Traditional Chinese medicine preparations accounted for 40% of the total medicine cost. Polypharmacy, overuse of injections, and improper use of antibiotics were major manifestations of the irrational use of medicines. Conclusion The selection and use of essential medicines should be base on high quality evidence as well disease burden, the economic situation and specific demands in different areas. Drug and therapeutics committees should be set up to perform dynamic monitoring, education, evaluation and continual improvement of an essential medicines list.
