Objective To evaluate and select essential medicine for diabetes mellitus based on the burden of disease. 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) Six guidelines were included, three of which were evidence-based and published from 2006 to 2011. (2) Five recommended medicines were included according to recommendations and evidence of WHOEML (2011), NEML (2009), CNF (2010) and other guidelines. They were metformin, glibenclamide, glipizide, rosiglitazone and pioglitazone. Domestic evidence of the first three drugs was evaluated. (3) The first three have been marketed with the specifications and dosage forms corresponding to guidelines in China. The FBG cost-effectiveness ratios of metformin with different dosage forms as immediate release compressed tablet, enteric-coated tablet and sustained release capsule were 3.37, 3.76 and 3.50 respectively. 2-hour BG cost-effectiveness ratios of metformin were 3.74, 4.00 and 3.71 respectively. The cost-effectiveness ratio of glibenclamide and glimepiride were 11.23 and 13.81 respectively. Conclusion We offer a recommendation for: (1) Metformin (immediate release tablet/capsule for oral use, 0.25 g), contraindicated in patients with renal insufficiency. (2) Glibenclamide (tablet, 2.5 mg; capsule, 1.75 mg) and glipizide (tablet, 2.5 or 5mg; dispersible tablet, 5 mg), contraindicated in children, women during pregnancy or lactation, patients in the perioperative period of major operation, patients after total pancreatectomy, and patients allergic or adversely reacted to sulfa drug. (3) Evidence-based and standardized primary healthcare guidelines as well as clinical and pharmacoeconomic studies on diabetes mellitus (large-scale, multi-centre, randomized and double-blinded) are needed to produce high-quality local evidence.
Objective To evaluate and select essential medicine for acute bronchitis using evidence-based methods based on the burden of disease. 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) Eight guidelines were included (seven foreign guidelines, one domestic guideline; five based on evidence, three based on expert consensus). (2) A result of six RCTs (n=816, low quality) indicated that pentoxyverine had efficiencies of 53% to 82% for cough relief. Among the six RCTs, a result of three RCTs (n=283) indicated that pentoxyverine was slightly less efficient than procaterol (RR=0.86, 95%CI 0.78 to 0.94, P=0.001); a result of two RCTs (n=233) indicated that pentoxyverine was slightly less efficient than Chinese medicinals decoction (RR=0.82, 95%CI 0.74 to 0.91, Plt;0.001). Adverse reaction of pentoxyverine (incidence: 0% to 2.4%) mainly covered nausea, palpitation, etc. Pentoxyverine cost 0.20 yuan (for adult) or 0.08 yuan (for child) daily, which was orally taken and applicable to the target population. (3) A result of six RCTs (n=403, low quality) indicated that the efficiencies of dextromethorphan for cough relief was 47.0% to 95.3%. Among the six RCTs, a result of one RCT (n=283) indicated that dextromethorphan hydrobromide (nasal drop) was more efficient than blank intervention (RR=3.71, 95%CI 1.91 to 7.21); a result of one RCT (n=43) indicated that dextromethorphan (for oral use) was more efficient than placebo (RR=1.74, 95%CI 1.13 to 2.66); a result of one RCT (n=300, moderate quality) indicated that dextromethorphan was more efficient than pentoxyverine (RR=1.16, 95%CI 1.07 to 1.26); a result of one observational study (n=121, low quality) indicated that dextromethorphan given for 5 days had an efficiency of 66.5%. Adverse reaction of dextromethorphan (incidence: 2% to 30%) mainly covered mouth dryness, dizziness, nausea, etc. Conclusion (1) We offer a b recommendation for dextromethorphan used in relieving dry cough due to acute bronchitis. (2) We offer a weak recommendation for pentoxyverine as symptomatic treatment for cough relief. (3) We make a recommendation against antibiotics, β2-agonist bronchodilators and mucolytic agents as routine use. (4) More large-scale, multi-center, double-blinded RCTs are needed in clinical and pharmacoeconomic studies of acute bronchitis in hopes of producing high-quality local evidence.
Objective To evaluate and select essential medicine for bone fracture using evidence-based methods based on the burden of disease. 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) 17 guidelines were included, six of which were evidence-based or based on expert consensus. We found that for fracture, global guidelines recommended surgical treatment and analgesics, while domestic guidelines recommended Chinese patent drugs. (2) A result of one RCT (low quality) indicated that Shang Ke Jie Gu Pian (name of a Chinese patent drug) shortened the clinical recovery time of fracture (MD=–4.2, 95%CI –5.25 to –3.14). A result of one RCT indicated that Shang Ke Jiu Ji Pian had a higher total clinical efficiency compared with San Qi Pian (name of a Chinese patent drug) (RR=1.28, 95%CI 1.11 to 1.47). A result of one RCT (low quality) indicated that Shang Ke Jiu Ji Pian (name of a Chinese patent drug) had a better effect than Shenyang Hong Yao Pian (name of a Chinese patent drug) in promoting the growth of osteotylus (RR=1.48, 95%CI 1.27 to 1.73) and also it had a higher clinical recovery rate (RR=1.62, 95%CI 1.37 to 1.9) compared to Shenyang Hong Yao Pian. A result of one RCT (moderate quality) indicated that Shang Ke Jiu Ji Pian was slightly better than Die Da Wan (name of Chinese patent drug) in regard to the recovery score of fracture (MD=0.25, 95%CI 0.026 to 0.47). A result of one RCT (low quality) indicated that compared to fracture reduction alone Shang Ke Jiu Ji Pian efficiently relieved pain (MD=–25.9, 95% –32.6 to –19.19) and shortened pain time (MD=–38.6, 95% –41.44 to –35.77). A result of one quasi-RCT (low quality) indicated that Shang Ke Jiu Ji Pian had a higher efficiency in relieving pain than benorylate (RR=1.13, 95%CI 1.04 to 1.23). A result of one RCT (low quality) indicated that Shang Ke Jiu Ji Pian had a higher efficiency than Shenyang Hong Yao Pian in relieving pain and swelling (RR=2.4, 95%CI 1.88 to 3.02). A result of one RCT (moderate quality) indicated that Shang Ke Jiu Ji Pian was superior to Die Da Wan in relieving pain and swelling (MD=–0.4, 95%CI –0.60 to –0.2). A result of two RCT (n=198) indicated that Shang Ke Jie Gu Pian caused no adverse reaction. With good applicability, Shang Ke Jie Gu Pian (taken with warm water or rice wine) cost 7.47 yuan daily. Conclusion (1) We offer a b recommendation for Shang Ke Jie Gu Pian and Jie Gu Qi Li Pian used in the treatment of adult fracture. (2) We should carry out more large-sample and controlled trials and improve outcome indicator in order to produce high-quality local evidence.
Objective To evaluate and select essential medicine for uterine neoplasms using evidence-based methods based on the burden of disease. 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) Six guidelines were included, three of which were evidence-based. (2) Retrieved guidelines related to nine medicines (of three classes) for uterine neoplasms and five adjuvant drugs (of three classes) used after relevant surgery. (3) According to WHOEML (2011), NEML (2009), CNF (2010), other guideline and the quantity and quality of evidence, we offered a b recommendation for medroxyprogesterone acetate, oxytocin, ergometrine and a weak recommendation for testosterone propionate, methyltestosterone, tamoxifen, mifepristone, tranexamic acid, leonurus heterophyllus used in the treatment of uterine neoplasms. We offered a recommendation against danazol and aromatase inhibitors. (4) We found relevant domestic literature on mifepristone, methyltestosterone, tamoxifen, oxytocin and leonurus heterophyllus. Mifepriston combined with methyltestosterone or tamoxifen was recommended to use as a conservative therapy for uterine neoplasms. Oxytocin,and leonurus heterophyllus were used to reduce bleeding after the surgery of uterine neoplasms. As to daily expense, mifepriston (25 mg/d) cost 13.0 to 27.5 yuan, methyltestosterone (5 mg/d) 0.074 yuan, tamoxifen (20 mg/d) 0.6 to 1.4 yuan, leonurus heterophyllus (injection, 1 mL) 15 yuan and oxytocin (injection, 20 U) 1.5 yuan. (5) Results of domestic studies indicated that mifepristone, mifepristone plus methyltestosterone, and mifepristone plus tamoxifen were proved to be safe and applicable for the treatment of uterine neoplasms. Oxytocin and leonurus heterophyllus are effective in preventing postoperative bleeding and the combination of two effectively and safely promoted uterine contraction. Conclusion (1) We offer a recommendation for three medication plans used in the treatment uterine neoplasms during perimenopause, including: a) Mifepristone (25 mg/ tablet, once daily); b) Mifepristone (25 mg/ tablet, once daily) plus methyltestosterone (5 mg/tablet, once daily); c) Mifepristone (25 mg/ tablet, once daily) plus tamoxifen (10 mg/tablet, twice daily). The three plans mentioned above should be used from first day of menstrual cycle, continuously for three months. (2) Adjuvant drugs such as oxytocin (injection, 1 to 2 mL) and leonurus heterophyllus (injection, 10 U) can be applied to reduce vaginal bleeding flow after the surgery of uterine neoplasms. (3) Personnel in elementary healthcare institution should stick to drug indication, carefully make follow-up, and dynamically monitor the change of uterine neoplasms and menstruation so as to adjust medication plan according to patients’ situation.
Objective To evaluate and select essential medicine for acute gastroenteritis 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 guidelines were included, two of which were evidence-based. (2) Recommended medicines included eight antidiarrheals (of four classes) and three antemetics. (3) According to WHOEML (2011), NEML (2009), CNF (2010), other guidelines and the quantity and quality of evidence, we offered a weak recommendation for ondansetron, metoclopramide, smectite, racecadotril and loperamide applied in the treatment of acute gastroenteritis. We made a recommendation against antibiotics, dexamethasone, kaolin-pectin, activated charcoal, attapulgite and bismuth subsalicylate. (4) Evidence from domestic studies: a result of 14 CCTs (n=1 635, low quality) indicated that in the significant efficiency and total efficiency, smectite (smecta) was superior to routine liquid infusion, norfloxacin, gentamicin or furaxone. Among these 14 CCTs, two CCTs reported smectite (smecta) caused nausea and vomiting (three cases); one CCT reported pain and distention in the abdomen (one case) and general discomfort (one case); and the rest reported no adverse reaction. A result of 10 CCTs (n=1 017, low quality) indicated that for acute diarrhea, racecadotril was superior to routine treatment in the significant efficiency (OR=2.55, 95%CI 1.64 to 3.94, Plt;0.01) and total efficiency (OR=4.32, 95%CI 2.96 to 6.30, Plt;0.01). A result of two CCTs (n=344, low quality) indicated that racecadotril was superior to smectite in the total efficiency in treating acute diarrhea. A result of two CCTs (n=1 056, low quality) indicated that racecadotril was superior to routine treatment in the total efficiency in treating acute adult diarrhea (OR=5.19, 95%CI 3.54 to 7.63, Plt;0.01). A result of two CCTs (n=182, low quality) reported children presented with nausea (two cases). A result of one CCT (n=947, low quality) reported adults presented with constipation (fifteen cases), anorexia (four cases), headache (nine cases) and abdominal pain (one case). Conclusion For acute gastroentitis, we offer a weak recommendation for smectite (powder, for oral use) used in adults (once 3 g, tid., mixed with warm water before intake), child under one year of age (3 g daily, bid.), and child above one year of age (once 3 g, qd. or bid.). Retention enema could be appiled to children with acute gastroenteritis. We also offer a weak recommendation for racecadotril (capsule) used in adults (one capsule, tid., taken continuously less than seven days). Due to the lack of evidence from clinical trials, we make a recommendation against racecadotril applied to women with pregnancy and lactation or children. In order to produce high-quality local evidence, we propose that (1) Further clinical studies should be standardized in diagnosis and criteria. (2) The design and implementation quality of clinical studies should be improved. (3) Original studies on pharmacoeconomic studies and drug applicability are needed.
Objective To evaluate and select essential medicine for middle-aged and elderly women with primary osteoporosis using evidence-based methods based on the burden of disease. 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) 18 guidelines were included, 14 of which were evidence-based or based on expert consensus. Recommended medicines included bisphosphonates, calcitonin, estrogen, parathyroid hormone, selective estrogen receptor modulator, strontium and Chinese patent drug. (2) A result of one quasi-RCT (very low quality) indicated that caltrate D had a better effect on elderly women with primary osteoporosis than calcium gluconate in improving bone mineral density (BMD) (MD=0.04, 95%CI 0.02 to 0.06) and ameliorating bone ache ( RR=2.64, 95%CI 1.40 to 4.96). A few cases treated by caltrate D presented with adverse reaction such as gastrointestinal discomfort, poor appetite, constipation and nausea which disappeared later. Caltrate D (calcium carbonate D3) with good applicability cost 1.00 yuan daily. (3) A result of one RCT (low quality) indicated that alendronate had a better effect than caltrate D in improving L2-L4 BMD (MD=0.06, 95%CI 0.017 to 0.10) and ameliorating bone ache (RR=1.8, 95%CI 1.40 to 2.52). A result of two RCTs (moderate quality) indicated that alendronate plus calcium carbonate plus vitamin D6 had a better effect than calcium carbonate plus vitamin D in improving L2-L4 BMD (MD=0.05, 95%CI 0.02 to 0.08) and reducing blood alkaline phosphatase (MD=–31.9, 95%CI –54.99 to –8.81). There were slight adverse effects mainly including gastrointestinal reaction. Alendronate with fairly poor applicability cost 2.67 yuan daily. (4) A result of one RCT (moderate quality) indicated that after a 3-month treatment, Xian Ling Gu Bao Jiao Nang (name of a Chinese patent drug, abbreviated as XLGB) plus calcium preparation had a better effect than calcium preparation alone (MD=10, 95%CI 0.05 to 0.15). A result of one RCT (moderate quality) indicated that given for 3 to 6 months, XLGB plus calcium preparation was superior to calcium preparation alone in increasing the density of Ward’s triangle and the great femoral trochanter. A result of one RCT (low quality) indicated that XLGB plus calcitriol had a better effect than calcitriol alone in pain relief (RR=1.26, 95%CI 1.04 to 1.52). There were slight adverse effects mainly including reaction in the digestive system, the circulatory system and the skin. XLGB with good applicability cost 4.58 yuan daily. Conclusion We offer a weak recommendation for alendronate applied to middle-aged and elderly women with primary osteoporosis and pain and fracture caused by primary osteoporosis. We also offer a b recommendation for caltrate D and XLGB applied to middle-aged and elderly women with primary osteoporosis and pain and fracture caused by primary osteoporosis. In addition, we propose that the census on elder people with osteoporosis in rural areas should be carried out. More clinical and pharmacoeconomic studies of large-sample, high-quality on alendronate and its calcium preparation for adult osteoporosis are needed in China.
Objective To evaluate and select essential medicine for children with fever and adult gastrointestinal flu caused by common cold 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) 12 guidelines were included, 11 of which were evidence-based or based on expert consensus. We offered a recommendation for medicines used in the treatment including analgesics and antipyretics, decongestants, antihistamines, cough-relieving drug, phlegm-removing drug and drug for gastrointestinal symptoms. (2) A result of four RCTs (very low quality) indicated that in the treatment of children with cold, ibuprofen suspension had an antipyretic effect similar to paracetamol solution (for oral use) with a pooled result of 6-hour efficiency in relieving fever (RR 1.48, 95%CI 0.66 to 3.30, P=0.34). The major adverse effects of ibuprofen suspension included gastrointestinal reaction and profuse sweats (RR=1.23, 95%CI 0.72 to 2.11, P=0.45). With good applicability, ibuprofen suspension (for oral use with no need to be supervised) cost 1.93 yuan daily. (3) A result of three RCTs (low quality) indicated that after given for 30 minutes and one hour, paracetamol solution (suppository) was fairly superior to ibuprofen suspension in lowering the high temperature caused by fever (given for 30 min: MD= –0.16°C, 95%CI –0.21 to –0.11, Plt;0.01; given for one hour: MD= –0.19°C, 95%CI –0.28 to 0.10, Plt;0.01). As to adverse reaction, paracetamol solution (suppository) mainly included anal irritation, skin rashes and profuse sweats, which had a comparative result of incidence with ibuprofen suspension (RR=1.84, 95%CI 0.62 to 5.44, P=0.27). For children with fever, paracetamol solution (suppository) cost 0.90 yuan daily. With good applicability, paracetamol solution (suppository) was administered via the anus. Conclusion (1) We offer a b recommendation for ibuprofen suspension (2 g/100 mL) or acetaminophen (0.1 g/suppository) as symptomatic treatment used in children with fever, pain and discomfort caused by common cold, and for Huo Xiang Zheng Qi Jiao Nang (0.3 g/ capsule) used in adults with gastrointestinal flu. We also offer a weak recommendation for acetylcysteine (injection, 300 mg/mL, 10 mL/ampoule) used in patients with paracetamol poisoning. (2) In order to produce high-quality local evidence, we proposed that large-scale, well-designed, high-quality clinical and pharmacoeconomic studies on ibuprofen suspension and acetaminophen suppository in the treatment of children with fever, pain and discomfort caused by common cold should be further carried out. Besides, we proposed that large-scale, well-designed, high-quality clinical and pharmacoeconomic studies on Chinese patent drugs of Huo Xiang Zheng Qi used in chidren and Huo Xiang Zheng Qi Jiao Nang used in adults should further carried out. Moreover, we suggest that epidemiological investigation as well as clinical and pharmacoeconomic studies of acetylcysteine injection for paracetamol poisoning should be carried out and the instructions of acetylcysteine injection should be added in the guidelines of essential medicine in China. Finally, further studies on evidence of oxymetazoline, dextromethorphan and other Chinese patent drugs with the effect of relieving cough and treating cold should be carried out.
Objective To evaluate and select essential medicine for acute and chronic gastritis 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 guidelines for acute gastritis and seven guidelines for chronic gastritis were included. The recommended included omeprazole, ranitidine and domperidone. (2) A result of three CCTs (n=315, low quality) indicated that omeprazole was superior to famotidine and ranitidine in alleviating symptoms of chronic gastritis such as pain or discomfort in the upper abdomen, regurgitation, a burning sensation in the heart, distention and fullness in the upper abdomen (71.2% vs. 47.3%, 94.4% vs. 84.3%, Plt;0.05). A result of one RCT (n=100, low quality) and two CCTs (n=213, low quality) indicated that in HP eradication rates, omeprazole triple therapy and the control intervention had no significant difference (OR=1.09, 95%CI 0.44 to 2.70, Pgt;0.05). A result of one RCT (n=100, low quality) indicated that omeprazole caused no adverse reaction. A result of five CCTs (n=528, low quality) indicated that adverse reaction of omeprazole included poor appetite (two cases), nausea and vomiting (four cases), headache or vertigo (one case) and increased transaminase (one case). Omeprazole cost eight yuan (tablet) or four yuan (capsule) daily. (3) HP eradication rates of ranitidine bismuth citrate was higher than the control group (OR=2.05, 95%CI 1.29 to 3.25, P=0.002). A result of 15 RCTs (n=3 638, high quality) indicated adverse reaction of ranitidine bismuth citrate mainly included symptoms in the digestive system. A result of one RCT (n=100, low quality) indicated ranitidine bismuth citrate and omeprazole triple therapy had no significant difference (Pgt;0.05) and ranitidine bismuth citrate caused no adverse reaction. Ranitidine cost 0.36 yuan (tablet), 0.40 yuan (capsule) or 2.7 to 5.4 yuan (injection) daily. (4) A result of two CCTs (n=133, low quality) indicated that compared with the control intervention, domperidone was more efficient without adverse reaction in improving indigestion, promoting gastric emptying effect, and alleviating pain and distention in the upper abdomen, belching and regurgitation. Domperidone cost 1 to 1.3 yuan daily. (5) All kinds of recommended medicines are listed and legalized in China Pharmacopoeia (2010) and CNF (2010). (6) In clinical setting, above-recommended medicines should be applied strictly according to the CNF (2010) and the National Clinical Prescription Guidelines for Essential Medicine. Conclusion For acute and chronic gastritis, indigestion and HP eradication: (1) We offer a b recommendation for omeprazole (immediate release tablet/capsule for oral use, 10 mg/tablet) which should be cautiously used in children, elderly people, and women during pregnancy or lactation. (2) We offer a b recommendation for ranitidine (immediate release tablet/capsule for oral use, 150 mg/tablet) which should be cautiously used in patients with severe insufficiency in the liver or kidney, women in the pregnancy or lactation, and children under eight years of age.
Objective To provide baseline data for further evidence-based evaluation and selection of essential medicine by analyzing the inpatient disease constitution in 8 pilot township health centers located in eastern, central and western China in 2010. Methods The analysis was performed to compare the similarities and differences of both systematic diseases and top 15 single diseases of inpatients in 8 pilot township health centers located in eastern, central and western China in 2010. The Microsoft Excel 2003 and SPSS 13.0 softwares were used for data classification and analysis, and the frequency and composition were used as describing statistical indicators. Results a) The top 5 systematic diseases were respiratory, digestive, circulatory, urinary tract and urogenital systems, as well as the trauma and toxicosis, with accumulative constituent ratio accounting for 71.0%-81.6%; b) The inpatients suffering from top 15 systematic diseases were 10 630, accounting for 61.10%. Each of the respiratory and digestive system contained 6 single diseases including 4 acute and 2 chronic ones, with inpatients accounting for 99.2% and 93.8%, respectively; the circulatory system contained 3 single diseases which were all chronic with inpatient ratio of 84.6%; and c) The chronic diseases were in majority within the top 15 single diseases, which were most commonly seen rather than acute diseases in the pilot township health centers in eastern and central China. The inpatients’ acute diseases were more often seen than chronic diseases in well-off and fundamental township health centers. Conclusion a) The top 5-6 systematic diseases are stable in the pilot township health centers in eastern, central and western China in 2010. The common single inpatient diseases are centralized, which benefits the selection and adjustment of essential medicine for the pilot township health centers in China; b) The capacity building of the western, fundamental and well-off township health centers to diagnose and treat inpatients suffering acute diseases should be promoted; c) The capacity building of the central and general township health centers to diagnose and manage inpatients suffering chronic diseases should be promoted; d) The capacity building of the eastern and well-off township health centers to provide outpatient service should be promoted. The function of the eastern township health centers needs further clarification and improvement; and e) More attention should be paid to diseases prevention, control and treatment for women, children, the elderly and the population with high burden of diseases.
Objective To evaluate and select essential medicine for chronic obstructive pulmonary diseases (COPD) using evidence-based methods based on the burden of disease. 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) Nine guidelines were included (eight foreign guidelines, one domestic guideline; seven based on evidence, two based on expert consensus). (2) A result of one domestic RCT (n=72, high quality) indicated that tiotropium could significantly improve pulmonary function of severe COPD patient complicated with respiratory failure and increase their quality of life (SGRQ score: MD=–10.8%, 95%CI –12.2% to –9.4%). A result of one RCT (n=156, moderate quality) with 3-month follow-up indicated that tiotropium could significantly improve the proportion of measured value to expected value of FEV1 in patients with mild and moderate COPD in stationary phase (MD=10.3%, 95%CI 8.1% to 12.5%). A result of two RCTs (n=160, low quality) indicated that compound ipratropium bromide had efficiencies of 84.2% to 87.5% for moderate and severe COPD. A result of one RCT (n=60, moderate quality) indicated that salmeterol/fluticasone (inhalation) was superior to placebo for improving mild and moderate COPD in stationary phase. A result of one RCT (n=725, moderate quality) indicated that tiotropium combined with salmeterol/fluticasone for COPD in stationary phase was superior to tiotropium alone. A result of one RCT (n=110, low quality) indicated that nebulized budesonide inhalation had an efficiency of 86.8% for acute exacerbation of COPD (AECOPD) and an incidence of 7.9% as to adverse reaction that mainly included laryngo-pharyngeal irritation. (3) Imipenem, meropenem, cefoperazone/ sulbactam and ceftazidime were effective for COPD with low drug resistance rates in treating COPD caused by non-ICU pathogens (less than 8%). Conclusion (1) We offer a b recommendation for tiotropium, ipratropium, salbutamol, formoterol, salmeterol and theophylline used in the treatment of COPD in stationary and exacerbation phases, a b recommendation for streptococcus pneumoniae and influenza vaccines in preventing the deterioration of COPD, a b recommendation for inhaled corticosteroids (ICS) used in the treatment of COPD in stationary phase and a b recommendation for corticosteroids (for oral use) for AECOPD. (2) We offer a b recommendation for cefoperazone/sulbactam, imipenem and meropenem used in the treatment of moderate and severe AECOPD. (3) We offer a weak recommendation for ceftazidime, ciprofloxacin, lavofloxacin, moxifloxacin, amoxicillin amp; clavulanate potassium, amoxicillin, azithromycin, clarithromycin and doxycycline as first-line and second-line antibiotics for mild and moderate AECOPD, and a weak recommendation for compound sulfamethoxazole, cefatriaxone, cefotaxime and cefuroxime used in the treatment of severe and extremely severe COPD, mucolytic agents used in the treatment of stable COPD with difficult expectoration. (4) We make a recommendation against antibiotics, expectorants and corticosteroids (for oral use) as routine use in stationary phase of COPD.
