ObjectiveComparing the worldwide Essential Medicines Lists for Children (EMLcs) and National Essential Medicine List (NEML) of China (2012 edition), to provide evidence for establishing EMLc of China.
MethodWe searched the official websites of WHO and Ministry of Health of some countries to identify published EMLcs. We compared the situation of updating, the number and classification of medicines, and the dosage forms between these EMLcs and NEML of China (2012).
ResultBy August 2013, the WHO, India and South Africa had established EMLc. The number of medicines of NEML of China (2012) ranked first in the four lists. The WHO, India and China classified the medicines by pharmacologic action, while South Africa classified it by anatomical therapeutic chemical (ATC) classification. Except the WHO, India, South Africa and China did not have specific medicines for neonatal care or medicines for diseases of joints. The main administration routes in these four lists were oral administration, injection, and topical application. There were medicine restrictions in EMLcs of WHO and India, while no medicine restrictions in lists of South Africa and China.
ConclusionMedicines listed in NEML of China (2012) do not match children's disease burden of China. The applicable dosage forms for children are few and the medicine restrictions are absent for the list. So this list is not suitable for Children.
ObjectiveTo access the current study status and the existing problems of studies on National Essential Medicines System (NEMS) in China based on systematic review methods, and provide the evidence-based evidence and references to the studies of this field.
MethodsThe following databases such as PubMed, EMbase, The Cochrane Library (Issue 3, March 2014), CNKI, WanFang Data, VIP and CBM were electronically searched to collect studies related to the policy analysis, implementation background, implementation strategies, implementation situation, implementation problem and implementation effects about NEMS in China. The retrieval time was from inception to December 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and finally conducted analysis on study types, study time, source journals, authors' units, study themes, etc. of the included studies.
ResultsA total of 1 607 articles were finally included, encompassing 56.38% qualitative studies and 43.62% quantitative studies. The number of published studies per year, the number of quantitative studies as well as the number of financiallysupported studies out of the total studies published per year had increased by year since 2009. The study topics focused on every parts during the implementation of NEMS in different proportions. The proportion of the national studies in the quantitative studies was lower than that of others. The regional distribution involved in the quantitative studies was unbalanced, and the ratio of which located on the East, the Central and the West of China was 2 to 1 to 1.
ConclusionThe implementation of NEMS and related studies are mutually promoted. More studies are needed to be carried out on remote areas as well as West China. Although the studies related to these areas tend to be standardized and evidence-based, but more in-depth studies should be well advanced. Most of the topics of the studies are widely covered, and the topics of further studies should be enforced in the detail of implementation links. Most of the studies focus on primary medical institutions, and more studies are also needed for supporting and expanding the implementation of NEMS in second and three degree medical institutions.
Objective To investigate current situation of medical service and management in Gaozha Central Township Health Center (GzC), so as to provide baseline data for township health centers in both key techniques research and product development of drugs allocation and delivery. Methods A questionnaire combined with a special interview was carried out, which included the general information, human resources, medical service and management, and the practice of essential medicine list. Results a) The hardware condition of GzC was not good enough, and the economic status of the service recipients was lower than the average level of both Wuzhong City and China mainland; b) The constituent ratio of general practitioner (GP) and nurse, and GP and laboratorian were all lower than those of national level, while, the constituent ratio of GP and technician was a little bit higher. GzC was in short of medical technical personnel and, especially, the professional pharmacists. The logistics technical workers were as the same proportion as the nurses. The medical technical personnel without professional education background accounted for 3.4%, and about 38% of the staff members had no college degree, about 86.2% had at most primary profession titles. There was no personnel turnover of GzC in recently years; c) The bed utilization ratio was lower than national level (46.4% vs. 60.7%), while the average duration of stay and the in-patient and out-patient service workload of GP were longer or heavier than national level (8 vs. 4.8, 9 vs. 8.3, 4 vs. 1.3); d) The out-patient service in 2010 decreased 26.9% compared to 2009; and the in-patient service in 2010 decreased 42.4%; e) The average medical expense per outpatient and per inpatient increased 127.3% and 56.2%, respectively in 2010 compared to 2009; and f) Essential medicine list was put into practice in April 1st of 2010 and there was only 195 species available in GzC, which has not met the requirements of the national essential medicine list. Conclusion In order to meet the standards of general rural township health center in western China, GzC needs to cope with challenges of insufficient hardware conditions, short of staff, unreasonable personnel structure, low educational background and professional title of the staff, none human resources flow and low technical level of medical service. GzC dose well in drug expenses control, and the hospitalization costs are lower than those of the national level. However, it increases rapidly in 2010. The management of GzC may be influenced by zero-profit sale of the essential drugs, and appropriate subsidy and policy support are necessary to maintain its service quality. And it is required to complement the medicine based on the evidences, to carry out staff training and usage guidance of essential medicine, and to finally guarantee the safe and reasonable use of medicines.
Objective To investigate the performance of Essential Medicine List (EML) policy over the past one year in Xintian Township Health Center (XTHC), so as to provide references for the delivery, storage and compensation mechanism of essential medicine for township hospitals. Methods Focus interview combined with a questionnaire was carried out to investigate the supply and usage of EML, the situation of both diagnosis-treatment services and the income-expenditure change before and after EML policy. Results a) It showed that there was an increasing trend with the preparation rate of EML from 62.2% before implementation to 87.3% after, and the proportion of EML income to total medicine expenses increased from 39.3% to 90.6% in XTHC. But problems still existed such as incomplete and old variety of medicine; b) The numbers of outpatient-time and inpatient-time kept growing, while medical cost for both average clinic cost and average hospitalization cost decreased to different extent; c) Although the gross income increased slightly, this center was still running in the red with the limited amount of financial assistance; and d) The proportion of medical care and drug kept decreasing while the proportion of drug cost and examination cost kept increasing. Compared with the situation in 2009, the proportion of examination cost from 2010 to 2011 had increased by 30%, and it still remained at the previous level after EML implementation. Conclusion The implementation of EML does not completely change the predicament of “Make compensation for doctors by selling drugs” in township health center. Owing to the sale policy of zero price difference and the poor performance of compensation for township health centers, XTHC is still running under deficit. Evidence-based medicine selection and research on compensation mechanism for underdeveloped areas are urgently needed.
Objective To evaluate the efficacy and safety of Polyunsaturated phosphatidylcholine (PPC) for chronic hepatitis. Methods We searched EMBASE (1980May,2003), MEDLINE(1966May,2003), CBM (1979May,2003), The Cochrane Library Issue 2, 2003 and handsearched 8 related Chinese journals. Randomized controlled trials(RCT) comparing PPC versus placebo/no treatment for chronic hepatitis were included with no restrictions of blinding, language and publication. Two reviewers independently performed data extraction and assessed the quality . Data were entered and analyzed by RevMan 4.2 software supplied by the Cochrane Collaboration .Results Six high quality trials involving 568 patients were included. Four studies involving 451 patients showed the clinical effective rate of PPC for chronic hepatitis was 52.5% while the control group was 37.5% with statistical difference [RR1.81,95%CI(1.41,2.33),Z=4.69, Plt;0.00001].A meta-analysis involving three studies with 100 patients showed the PPC can statically improve histopathology of chronic hepatitis comparing with control group [RR 2.58,95%CI (1.61,4.15),Z=3.91,Plt;0.0001].No serious adverse events were reported.Conclusions PPC is a safe medicine used for treating chronic viral hepatitis and may relieve clinical symptoms and signs.At the same time ,it has positive effect on hepatic histopathology for patients .However ,more high quality clinical trials are required.
Objective?To evaluate and select essential antihypertensive medicine using evidence-based approaches based on the burden of disease for township health centers located in eastern, central and western regions of China. Methods?By means of the approaches, criteria, and workflow set up in the second article of this series, we referred to the recommendations of evidence-based or authority guidelines from inside and outside China, collected relevant evidence from domestic clinical studies, and recommended essential medicine based on evidence-based evaluation. Data were analyzed by Review Manager (RevMan) 5.1 and GRADE profiler 3.6 to evaluate quality of evidence. Results?(1) Five clinical guidelines on hypertension were included, two of which were evidence-based. (2) Totally there were nine classes and 70 antihypertensive medicines listed in the guidelines. (3) According to WHOEML (2011), NEML (2009), CNF (2010), other guidelines, and the quantity and quality of evidence, we offered a b recommendation for nifedipine, verapamil and enalapril and a weak recommendation for hydrochlorothiazide, indapamide, spironolactone, propranolol, metoprolol and amlodipine. We made a recommendation against furosemide and timolol due to the lack of evidence from guidelines. (4) Nine recommended medicines have been marketed with the dosage forms and specifications corresponding to guidelines in China. The prices of metoprolol, amlodipine and enalapril were higher than those of other six (daily cost: metoprolol 3.80 to 7.60 yuan, amlodipine 2.16 to 4.32 yuan, and enalapril 0.86 to 6.88 yuan). As a whole, the prices of recommended antihypertensive medicine were affordable. (5) Results of domestic studies indicated that three bly-recommended medicines (including nifedipine, verapamil and enalapril) were safe, effective, economical and applicable. Conclusion?(1) We offer a b recommendation for nifedipine, verapamil and enalapril as antihypertensive medicine and a weak recommendation for hydrochlorothiazide, indapamide, spironolactone, propranolol, metoprolol and amlodipine. (2) There is lack of high-quality evidence from relevant domestic studies, especially on long-term safety and pharmacoeconomic evidence. (3) We propose that more studies should be carried out on the safety, efficacy and pharmacoeconomics of six medicines for which we make a weak recommendation to produce high-quality local evidence.
Objective Healthcare risk has become a popular topic in medical research field all over the world. With the increasing of healthcare safety adverse events and medical conflict cases every year, publications about this topic have been rapidly increased in China, but research on the essentials and categories of healthcare risk are still lacked. This paper aims to summarize the essentials and categories of healthcare risk research systematically through analyzing domestic studies in healthcare risk over the past decade, so as to provide decision-making evidences and policy suggenstions on healthcare risk management in China. Methods We searched the China Academic Journal Network Publishing Database of CNKI (1999-2010), in which those papers’ title containing the phrase of healthcare risk had been brought into our research, then we summerized the domestic concepts and contents in healthcare risk by essential analysis and frequency statistics. Results 255 papers were included, including 26 Class B papers (accounting for 10.20%), six Class C papers (accounting for 2.35%) and 223 Class D papers (accounting for 87.45%); but there were only 79 papers (accounting for 35.11% ) which had a clear definition of healthcare risk. From these papers, we found the essentials of healthcare risk included object, consequences, process and causes, and the research category of healthcare risk included prevention and treatment of risk, causes and effects of factors, risk sharing mechanisms, healthcare risk of special diseases, concept and characteristics, education and training, management method, risks of medical appliances, the species and object of healthcare risk, the category of healthcare risk, the research methods of healthcare risk etc. Conclusion At present, the study of healthcare risk focuses on the risk control and how to release risks from the results, besides, systematic studies are lacked, and the unified definition of healthcare risk has not been formed, Therefore, we recommend that systematic study of the healthcare risks should be strengthened, the definition of healthcare risk should be unified, and the early warning, monitoring, evaluating, and identifying methods should be positively developed, providing decision-making evidences to establish healthcare risk management system in China.
Objective To observe the effect of combination of antihypertensive and lipid lowering therapy on arterial stiffness in elderly patients with mild to moderate essential hypertension. Methods A total of 216 elderly patients with mild to moderate essential hypertension were enrolled and treated by hydrochlorothiazide as the basic therapy for two weeks. Then the patients were randomly divided into four groups. Namely, the intensified antihypertensive and lipid lowering therapy group (hydrochlorothiazide 25 mg/d, Candesartan 8 mg/d, Rosuvastatin 10 mg/d, n=54), the intensified antihypertensive treatment group (hydrochlorothiazide 25 mg/d, Candesartan 8 mg/d, n=54), the antihypertensive and lipid lowering therapy group (hydrochlorothiazide 25 mg/d, Rosuvastatin 10 mg/d, n=54), and the control group (hydrochlorothiazide 25 mg/d, n=54). After 12-month treatment, the blood pressure, blood lipid and carotid-radial pulse wave velocity (crPWV) of each group were recorded. Results Twelve months later, the SBP, DBP, PP and crPWV of each group were significantly lower than before (Plt;0.05). There was interactive effect of antihypertensive and lipid lowering therapy in lowering SBP, DBP, PP and crPWV (F=40.765, 4.869, 24.829, and 53.149, respectively, all Рlt;0.05). Conclusion The combination of antihypertensive and lipid lowering therapy can significantly lower the crPWV of elderly patients with hypertension and improve the arterial stiffness; it is superior to single treatment of either antihypertensive or lipid lowering.
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.
Objective To assess the efficacy and safety Losartan for essential hypertension associated withhyperuricemia. Methods Included randomized controlled trials of Losartan versus Valsartan. Electronic searchconducted in CENTRAL, the Cochrane Library (until 2008, Issue 4), PubMed, EMBASE, Chinese Biomedicine database,Chinese Scientific Journals Full-text Database, and China Journal Full-text Database (until 2008, Issue 10). Two reviewers extracted data independently. RevMan 5.0 software developed by the Cochrane Collaboration was used for Metaanalysis.Results Only 7 trials with 1 136 eligible patients were included in the systematic review. Meta-analysis showedno significant difference in reductions of systolic blood pressure, diastolic blood pressure, and adverse events betweenLosartan and Valsartan groups. However, a significant difference of serum uric acid reduction was observed betweenLosartan and Valsartan group. Losartan play a significant role of decreased serum uric acid levels. Conclusions Based on this systematic review, Losartan is effective and well tolerated in reducing BP and serum uric acid levels. Further large randomized, double blind, placebo controlled trials are needed in long-term safety and efficacy and different subgroups of Losartan.
