ObjectiveTo overview of systematic reviews (SRs) of Yiqi Fumai (YQFM) injection in the treatment of chronic heart failure (CHF). MethodsThe PubMed, Cochrane Library, EMbase, Web of Science, CNKI, CBM and WanFang Data databases were electronically searched to collect SRs of YQFM injection in the treatment of CHF from January 1, 2007 to October 31, 2022. Two reviewers independently screened literature, extracted data and assessed methodological quality, risk of bias, report quality and evidence quality by using AMSTAR-2, ROBIS scale, PRISMA, and GRADE system. ResultsA total of 7 SRs were included. The evaluation results showed that the quality of all SRs was low, a few SRs were assessed as having a low risk of bias, and all SRs were relatively completely reported. A total of 46 results were extracted from the included SRs, including 3 with moderate quality evidence, 12 with low quality evidence and 31 with very low quality evidence. ConclusionYQFM may be an effective and safe treatment, but current evidence quality is low.
ObjectiveTo retrieve and summarize the clinical studies on traditional Chinese medicine for heart failure prevention and treatment and to observe the distribution of evidence in the field of heart failure by using the method of evidence map.MethodsPubMed, Web of Science, EMbase, CNKI, WanFang Data and VIP databases were searched from January 2000 to January 2020. Clinical studies, systematic reviews, guidelines, and clinical pathways related to traditional Chinese medicine for heart failure prevention and treatment were included, and the distribution characteristics of evidence were analyzed by using charts and text descriptions.ResultsA total of 8 580 papers were included, including 8 398 clinical studies (6 821 randomized controlled trials, 1 109 non-randomized controlled trials and 468 observational studies), 160 systematic reviews, and 22 guidelines, expert consensus and pathway studies. The number of clinical studies domestically and abroad showed an overall growth trend. The sample size was concentrated in 60- 100 cases. Coronary atherosclerotic heart disease was the most common comorbidity of heart failure. AMSTAR scores of systematic reviews were primarily 4 to 8. The results of high-quality randomized controlled trials and systematic reviews showed that traditional Chinese medicine combined with conventional Western medicine in the treatment of heart failure had certain advantages in improving heart function, quality of life and prognosis.ConclusionsHigh-quality clinical studies show that traditional Chinese medicine has certain advantages in the efficacy and safety of heart failure prevention and treatment; however, few studies have high methodological quality. In the future, multi-center, large sample size, and high methodological quality clinical studies are needed to further explore the efficacy and safety of traditional Chinese medicine therapy in the field of heart failure.
ObjectiveTo overview the systematic reviews of the efficacy of cancer patient decision aids (PDAs) for treatment decision-making. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CINAHL, JBI, CNKI, VIP, CBM and WanFang Data databases were electronically searched to collect the systematic reviews relevant to the objective from inception to September 2023. Literature screening, data extraction, methodological quality assessment of the included literature, and summary and grading of the evidence were carried out independently by two researchers, and duplication of original studies in the included systematic evaluations was investigated using the corrected covered area (CCA). ResultsA total of 17 systematic reviews were included, of which 13 (76.47%) were low- or very low-quality studies. A total of 64 pieces of evidence were included, of which only 26 (40.62%) were of moderate quality, and the original studies included in the included literature had a low degree of overlap (CCA=0.05). The results of meta-analysis showed that PDAs could increase decision-related knowledge, reduce decision conflict and regret in cancer patients' treatment decision (P<0.05). However, there was no significant difference in decision satisfaction, anxiety or depression (P>0.05). ConclusionPDAs can improve cancer patients' knowledge related to treatment decision, reduce decision conflicts and regrets, and have no significant negative effects on decision preparation, satisfaction, anxiety, and depression. However, the existing systematic reviews are of low quality and limited to a few cancer types.
ObjectivesTo evaluate the quality of methodology and evidence of the exiting systematic reviews (SRs) of acupuncture therapy for post-stroke spastic paralysis.MethodsCNKI, CBM, The Cochrane Library, PubMed and EMbase databases were electronically searched to collect SRs of acupuncture therapy for post-stroke spastic paralysis from inception to December 16th, 2018. Two reviewers independently screened literature, extracted data, and evaluated the quality of methodology and evidence by AMSTAR 2 scale and GRADE system.ResultsA total of 7 SRs were included. The results showed that acupuncture therapy had obvious advantages in treating post-stroke spastic paralysis without obvious adverse reactions. The results of AMSTAR 2 scale showed that the failure of key items 2 and 7 resulted in extremely low methodological quality. The results of GRADE system showed that 46.15% of which were low-level evidence quality, 42.31% were medium, 11.54% were extremely low, and no evidence quality were high.ConclusionsCurrent evidence shows that acupuncture and moxibustion therapy is effective in treating spastic paralysis after stroke, however, the quality of the SRs is low. The studies are required to be standardized and combined with the characteristics of TCM to obtain high quality evidence in the future.
ObjectiveTo re-evaluate the systematic review and meta-analysis (SR/MAs) of the efficacy of robot-assisted pedicle screw placement. MethodsThe CNKI, VIP, WanFang Data, SinoMed, PubMed, Embase, Cochrane Library, and Web of Science databases were electronically searched to collect SR/MAs of robot-assisted pedicle screw placement from inception to April 28, 2023. Two reviewers independently screened literature, extracted data and then assessed the quality of reports, methodological quality, risk of bias, and the strength of evidence quality by using PRISMA, AMSTAR-Ⅱ, ROBIS, and GRADE tool. ResultsA total of 20 SR/MAs were included. The results of the included studies showed that robot-assisted pedicle screw placement was more accurate and had a lower number of complications compared with freehand pedicle screw placement. The quality of reports, methodology, and evidence for pedicle screw placement efficiency in all SR/MAs were low or extremely low, with a high risk of bias. The main reasons included high heterogeneity of included studies, unclear research methods and selection criteria, and missing key reporting processes. ConclusionRobot-assisted pedicle screw placement may have better clinical efficiency than traditional freehand pedicle screw placement. But the quality of relational SR/MAs is low.
Objective To overview the systematic reviews about the efficacy and safety of respiratory fluoroquinolones for community-acquired pneumonia (CAP). Methods We electronically searched databases including China National Knowledge Internet, WanFang Data, VIP, PubMed, Embase and The Cochrane Library to collect systematic reviews or Meta-analyses about respiratory fluoroquinolones for CAP from inception to November 2, 2017. Two reviewers independently screened literatures, extracted data, and then AMSTAR tool was used to assess the methodological quality of included studies. Results A total of 18 systematic reviews/Meta-analyses were included. The results of quality assessment indicated the scores ranged from 5 to 10. Among the 11 items, the item 1 of " Was an ‘a priori’ design provided” and item 4 " Was the status of publication (i.e. grey literature) used as an inclusion criterion” appeared to be the most problematic. The results of overview suggested that: the efficacy of respiratory fluoroquinolones might be similar to β-lactams plus macrolides combination treatment for CAP. However, respiratory fluoroquinolones might be more safety. In addition, the efficacy of respiratory fluoroquinolones sequential therapy for CAP was similar to that of continuous intravenous therapy, but the adverse reactions of the former were fewer. Conclusions Respiratory fluoroquinolones might be similar in efficacy for CAP to other antibiotics recommended by the guidelines with less adverse reactions. However, it can increase multi-drug resistance and potential tuberculosis drug resistance, we should strictly follow the principle of rational use of antibiotics to avoid abuse.
ObjectiveTo evaluate the risk of bias and reliability of conclusions of systematic reviews (SRs) of lung cancer screening. MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 2, 2016), Web of Knowledge, CBM, WanFang Data and CNKI to collect SRs of lung cancer screening from inception to February 29th, 2016. The ROBIS tool was applied to assess the risk of bias of included SRs, and then GRADE system was used for evidence quality assessment of outcomes of SRs. ResultsA total of 11 SRs involving 5 outcomes (mortality, detection rate, survival rate, over-diagnosis and potential benefits and harms) were included. The results of risk of bias assessment by ROBIS tool showed:Two studies completely matched the 4 questions of phase 1. In the phase 2, 6 studies were low risk of bias in the including criteria field; 8 studies were low risk of bias in the literature search and screening field; 3 studies were low risk of bias in the data abstraction and quality assessment field; and 5 studies were low risk of bias in the data synthesis field. In the phase 3 of comprehensive risk of bias results, 5 studies were low risk. The results of evidence quality assessment by GRADE system showed:three studies had A level evidence on the outcome of mortality; 1 study had A level evidence on detection; 1 study had A level evidence on survival rate; 3 studies on over-diagnosis had C level evidence; and 2 studies on potential benefits and harms had B level evidence. ConclusionThe risk of bias of SRs of lung cancer screening is totally modest; however, the evidence quality of outcomes of these SRs is totally low. Clinicians should cautiously use these evidence to make decision based on local situation.
ObjectiveTo overview of systematic reviews of the efficacy and safety of antimicrobials in the prevention of postpartum infection after vaginal delivery, and to provide evidence for the rational use of antimicrobials. MethodsThe CNKI, WanFang Data, VIP, PubMed, Embase, and Cochrane Library databases were searched to collect systematic reviews/meta-analyses on antibiotic prophylaxis for transvaginal delivery from inception to June 25, 2023. The data of the included systematic reviews were extracted by 2 investigators independently, and the methodological quality, risk of bias, and report quality were evaluated by AMSTAR 2.0 scale, ROBIS tool, and PRISMA, respectively. And a pool of outcomes for assessing the effectiveness of antimicrobials in prevention of postpartum infection after transvaginal delivery was developed. ResultsA total of 7 systematic reviews were included. And the AMSTAR 2.0 indicated that most studies (5/7) were from very low quality to low quality. The ROBIS tool showed 3 studies with low risk of bias, 3 with high risk of bias, and 1 with unclear risk of bias. The results of the PRISMA statement showed that the included system evaluation reports were relatively complete. The present evidence showed that prophylactic use of antimicrobials may be beneficial and recommended in women with Ⅲ-Ⅳ perineal fissures, with no significant benefit in women with manual placenta removal, but prophylactic use of antimicrobials was recommended considering their invasive nature, but it was controversial whether antimicrobials should be used in the categories of vaginal assisted delivery, perineal lateralization, and spontaneous delivery (without complications). ConclusionAntimicrobial prophylaxis may not be recommended for all the pregnant women undergoing vaginal delivery to prevent the postpartum infection, but considering the low methodological quality of the included systematic review and the inconsistent outcomes in this field, the conclusion should be further verified by future research with high-quality.
ObjectivesTo provide an overview of whether the clinical decision support system (CDSS) was effective in reducing medication error and improving medication safety and to assess the quality of available scientific evidence.MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data, VIP and CNKI databases were electronically searched to collect systematic reviews (SRs) on application of clinical decision support system in the medication error and safety from January, 1996 to November, 2018. Two reviewers independently screened literature, extracted data and then evaluated methodological quality of included SRs by using AMSTAR tool.g AMSTAR tool.ResultsA total of 20 SRs including 256 980 healthcare practitioners and 1 683 675 patients were included. Specifically, 16 studies demonstrated moderate quality and 4 demonstrated high quality. 19 SRs evaluated multiple process of care outcome: 9 were sufficient evidence, 6 were limited evidence, and 7 were insufficient evidence which proved that CDSS had a positive effect on process outcome. 13 SRs evaluated reported patient outcomes: 1 with sufficient evidence, 3 with limited evidence, and 9 without sufficient evidence.ConclusionsCDSS reduces medication error by inconsistently improving process of care measures and seldom improving patient outcomes. Larger samples and longer-term studies are required to ensure a larger and more reliable evidence base on the effects of CDSS intervention on patient outcomes.
ObjectiveTo overview the systematic reviews on efficacy and safety of hyperbaric oxygen in treatment of diabetic foot.MethodsCNKI, CBM, VIP, WanFang Data, The Cochrane Library, PubMed and EMbase databases were searched to collect systematic reviews or meta-analyses on the efficacy and safety of hyperbaric oxygen therapy for diabetic foot from inception to November 17th, 2019. Two researchers independently screened literature and extracted data. Then, AMSTAR 2 tool and PRISMA statement were used to evaluate the methodological quality and reporting quality of included systematic reviews, and the outcome indicators were comprehensively analyzed.ResultsA total of 10 systematic reviews were included. The results of AMSTAR 2 suggested that 6 systematic reviews were of extremely low quality, 3 of low quality, and 1 of high quality. The PRISMA score ranged from 16.5 to 27. The results of the included systematic reviews showed that hyperbaric oxygen therapy might be superior to other interventions in ulcer healing rate and large amputation rate without increasing the risk of adverse events. ConclusionsThe existing systematic reviews/meta-analysis evidence shows that hyperbaric oxygen therapy may have certain curative effect on diabetic foot, however, its methodology and report quality evaluation are insufficient.
