Abstract
Objective To assess the effects of management by diabetes specialist nurse (DSN) on blood glucose control. Methods A comprehensive search of databases was carried out including PubMed, the Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) , Chinese Biomedical Literature Database (CBM), China Scientific Journal Database (VIP) and Wanfang Database from their inception to November 2013 in any language to identify trials. Searching of relevant publications was undertaken to identify additional trials. Randomized controlled trials and quasirandomized controlled trials dealing with the effects of management by DSN on glycosylated hemoglobin (HbA1c) were included in the review. Two investigators performed data extraction and quality assessment independently. Statistic analysis were carried out using RevMan5.2 software. Results Eighteen trials were included finally. Meta-analysis showed that management by DSN can better control the blood glucose of patients(WMD=-0.63, 95%CI-0.88--0.38), but the effect was influenced by intervention time, location and type of the diabetes mellitus. Conclusions The presence of a DSN can improve patients' blood glucose control, especially in the long-term control of blood glucose. Key words: Diabetes mellitus; Meta-analysis; Diabetes specialist nurse
