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.
ObjectivesTo evaluate the methodological bias and the reliability of the conclusions of systematic reviews (SRs) of lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library, PROSPERO, CNKI, CBM, WanFang Data and VIP to collect systematic reviews and meta-analysis about lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia from inception to August 31st, 2016. Two reviewers independently screened literature and extracted data, then AMSTAR tool was used to assess the methodological quality of included studies and the GRADE tool was used to grade the evidence quality of outcome measures included in the SRs. ResultsA total of eight relevant SRs were included and containing three main outcome measures. The assessment results of AMSTAR tool suggested that:four SRs were of high quality, and the other four were of medium quality. GRADE results showed:for serum phosphorus level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, four SRs were low, low, low and very low; compared with sevelamer, one SR was low. For serum calcium level, compared with placebo, the quality of the evidence of three SRs were high, medium and low, respectively; compared with calcium carbonate or conventional phosphorus binder, five SRs were low, low, low, very low and very low; compared with sevelamer, one SR was very low. For serum iPTH level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, five SRs were medium, low, low, very low and very low; compared with sevelamer, one SR was low. ConclusionAt present, methodological quality assessment for the treatment of hyperphosphatemia in chronic kidney disease with lanthanum carbonate is generally not high and the level of evidence for the conclusion is generally low. In drug safety, especially in the occurrence of adverse events of the digestive system is still controversial, and a large amount of high quality experimental is needed to demonstrate the safety of its long-term use. Clinicians need to be cautious in using these evidence to make clinical decisions.
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.
Objective To overview the systematic reviews/meta-analyses of efficacy of FNB used as a postoperative analgesic technique among patients undergoing TKR. Methods We electronically searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data and VIP from inception to July, 2016. Two reviewers independently screened literature and extracted data. AMSTAR tool was used to assess the methodological quality of included studies. The primary outcome was pain scores and the consumption of opoid medicine to evaluate the effectiveness of FNB. Results A total of 16 systematic reviews/meta-analyses were included, involving the FNBvs. LIA, PMDI, EA, PCA and ACB, respectively. The results of quality assessment indicated medium scores with 3 to 9 scores. The overviews’ results showed that: at rest, FNB was not superior to LIA at 6h after TKR; it was superior to PMDI at 12h after TKR; it was also superior to PCA and LIA, but not superior to ACB at 24h after TKR. On movement, FNB was superior to PCA and LIA at 24h after TKR; it was also superior to PCA at 48h after TKR. As to the consumption of opoid medicine, the consumption in FNB group was more than LIA group at 12h after TKR. In addition, the consumption in FNB group was less than PCA and LIA at 24h after TKR, and it was also less than PCA and ACB at 48h. The satisfaction of patients who received FNB was better than ACB, EA and PCA. Conclusion The current overview shows that FNB is more effective than PCA and LIA, the patients’ satisfaction is better. Due to the limitations of the quantity and quality of included studies, the above conclusions are needed to be verified by more studies.
Objectives To overview the systematic reviews/meta-analyses of safety of femoral nerve block (FNB) used as a postoperative analgesic technique in patients undergoing total knee arthroplasty (TKA). Methods We searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data, and VIP from inception to July, 2016. Two reviewers independently screened literature, extracted data and used AMSTAR to evaluate the methodological quality of the included studies. The major indexes used to evaluate the safety of FNB were the incidence rates of symptoms including nausea, vomiting, sedation, retention of urine, dizziness, pruritus, hypotension, falls, nenous thromboembolism and deep infection. Results A total of 12 systematic reviews/meta-analyses were included.They assessed the safety of FNB compared with local infiltration analgesia (LIA), periarticular multimodal drug injection (PMDI), epidural analgesia (EA), patient-controlled intravenous analgesia of opioids (PCA) and adductor canal block (ACB), respectively. The methodological quality of included studies were medium, with the scores between 3 to 10. The results of overview indicated that: FNB had lower incidence rates of nausea and vomiting compared with EA and PCA, but had higher than ACB. FNB had lower incidence rates of sedation and retention of urine compared with EA and PCA. FNB had lower incidence rates of dizziness compared with EA and PCA, and lower incidence rate of hypotension compared with EA. Conclusion Current evidence suggests that FNB is safer than EA and PCA. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
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.
ObjectiveTo evaluate the quality of methodology and evidence of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture therapy for bronchial asthma. MethodsCNKI, CBM, VIP, WanFang Data, PubMed, The Cochrane Library and Web of Science databases were electronically searched to collect SRs/MAs of acupuncture therapy for bronchial asthma from inception to October 31, 2021. Four reviewers independently screened literature, extracted data, and applied the AMSTAR 2 to evaluate the quality of methodology of the included studies and the GRADE system to assess the certainty of evidence for outcomes. ResultsA total of 14 SRs/MAs were included and their main conclusions were that acupuncture therapy was beneficial in improving the clinical efficacy of bronchial asthma treatment. The evaluation of AMSTAR 2 showed that the methodological quality of all studies was all extremely low. The evidence grading of GRADE system showed that, in the total of 59 outcomes, 7 were graded as medium-level, 24 as low-level, 28 as extremely low-level, and none was graded as high-level. ConclusionThe current evidence shows the advantages of acupuncture therapy for bronchial asthma but the reliability of SRs/MAs is low. High-quality clinical studies are still needed to verify the efficacy of acupuncture therapy for bronchial asthma.
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 overview the systematic reviews/meta-analyses (SRs/MAs) of effectiveness and safety of spinal manipulation for low back pain or neck pain. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 1, 2015), CBM, CNKI, WanFang Data and VIP to collect SRs/MAs of spinal manipulation for low back pain or neck pain from inception to January 30th, 2015. Two reviewers independently screened literature, extracted data, and then AMSTAR tool was used to assess the methodological quality of included SRs/MAs. ResultsA total of 21 SRs/MAs were included. Twenty of them assessed the methodological quality of included original randomized controlled trials (RCTs) with different tools:2 used Jadad scale, 5 used PEDro scale, 6 used Cochrane bias risk assessment tool and 7 used other tools. The assessment results of AMSTAR tool suggested that:among 11 items, the item 1 of "Was an ‘a priori’ design provided" (18 SRs/MAs did not provide) and item 4 of "Was a list of studies (included and excluded) provided" (18 SRs/MAs did not provide) appeared to be the most problematic, followed by item 10 of "Was the likelihood of publication bias assessed" (14 SRs/MAs did not assess the publication bias) and item 11 of "Was the conflict of interest stated" (14 SRs/MAs did not provide the conflict of interest and 4 were incomplete). ConclusionThe methodological quality of included SRs/MAs is poor. The limited evidence showed that spinal manipulation is more effective for acute low back pain than chronic low back pain, and the short term effect is better than the long term one. Different spinal manipulation techniques have various effects but are all safe. Chiropractic manipulation may have the best effect. Due to the limitation of quality and quantity of included SRs/MAs, there may be potential bias in the above conclusion that needs more high quality studies to verify.
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.
