Systematic review of the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes

BackgroundType 1 and 2 diabetes care, especially within primary health-care settings, has traditionally involved doctor-led clinics. However, with increasing chronic disease burden, there is scope for nurses to expand their role in assisting diabetes self-management. AimsThis study aimed to determine the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes. MethodsMethodology from the Joanna Briggs Institute Method for Systematic Review Research and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, including identifying publications, assessing study quality, summarizing evidence and interpreting findings. The search strategy involved using the Medical Subject Headings and keyword variations when searching MEDLINE (Ovid), Scopus, PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Inclusion criteria were samples with Type 1 or 2 diabetes, mean age of >= 18 years, English language studies and publication date of January 2011-December 2021. ResultsOverall, 34 articles from 16 countries met inclusion criteria. Though not always clinically significant, results indicated that nurse-led care had beneficial impacts on glycated haemoglobin values, with reductions from 0.03% to 2.0%. This was evident when nurses received formal training, used treatment algorithms, had limited medical support, utilized technology and offered defined culturally sensitive and appropriate diabetes care. ConclusionsFindings support nurse-led Type 1 and 2 diabetes care. Although further research is required, changes may necessitate increased recognition of nurse-led care and funding. Nurse-led care models should differ according to health-care settings.
