ObjectiveTo analyze and reduce the defects in nursing records for blood transfusion by continuous quality improvement (CQI) method, in order to prevent blood transfusion related medical disputes. MethodsIn October 2014, CQI team was established to analyze the reason for transfusion record defects and make standardized process and quality monitoring forms for nursing record of blood transfusion. Six months after the implementation of CQI, 40 records were randomly selected before the CQI implementation (April to September 2014) and after the implementation (April to September 2015) for comparison and analysis. ResultAfter 6 months of implementation of CQI, nursing record defects of blood transfusion decreased significantly from 228 to 55 items. ConclusionUsing CQI method can effectively reduce nursing record defects of blood transfusion. CQI can also improve the quality of nursing records and prevent medical disputes caused by blood transfusion.
ObjectiveTo assess the comparative efficacy of all kinds of selenium supplementation in the treatment of patients with Kashin-Beck disease (KBD) by network meta-analysis. MethodsWe searched seven electronic databases including PubMed, EMbase, The Cochrane Library (Issue 7, 2016), CBM, VIP, WanFang Data and CNKI databases up to July 2016. All randomized controlled trials (RCTs) assessing the effect of selenium supplementation on KBD were included. Two reviewers independently screened literatures, extracted data and assessed the risk bias of included studies, and then meta-analysis was performed by using Stata13.1 software. ResultsA total of 16 RCTs involving 2 883 participants were included. Direct meta-analysis comparison showed that:Compared with placebo or blank group, sodium selenite (OR=5.00, 95%CI 3.21 to 7.78), selenium supplement salt (OR=7.60, 95%CI 2.34 to 24.67), and combination of sodium selenite and vitamin E (OR=11.05, 95%CI 2.61 to 46.80) had higher metaphysis X-ray improvement (P < 0.05). Ranking on efficacy indicated that combination of sodium selenite and vitamin E were highest, followed by selenium supplement salt, sodium selenite, sodium selenite plus vitamin C, vitamin C, and placebo/blank. ConclusionBased on the results of network meta-analysis, selenium supplement (sodium selenite, combination of sodium selenite and vitamin C, combination of sodium selenite and vitamin E, as well as selenium salt) is more effective than placebo or no treatment in promoting the repairement of metaphysis impairment. The effect of combination of sodium selenite and vitamin E are highest.
