The effect of nurse‐led telephone‐based interventions on glycosylated hemoglobin levels in people with type 2 diabetes: A meta‐analysis

Abstract

AbstractBackgroundTelenursing interventions can contribute to achieving optimal glycemic control.AimThis meta‐analysis aimed to determine the effect of nurse‐led telephone‐based interventions on glycosylated hemoglobin (HbA1c) levels in people with type 2 diabetes.MethodsWe searched electronic databases for studies published in English up to January 2023. This study was conducted in accordance with the PRISMA 2020 checklist. The intervention effects were pooled using a random‐effects model. Two authors independently assessed the risk of bias using the Cochrane Collaboration tool.ResultsEight studies involving 1179 people with type 2 diabetes were included in this study. Interventions were performed for 15–30 min and 5–16 calls. There was no evidence of a significant publication bias. The evaluation of meta‐analysis data showed that nurse‐led telephone‐based interventions significantly reduced HbA1c levels in people with type 2 diabetes (mean difference = −0.53, 95% Confidence Interval [−0.89, −0.17], p = .003).Linking Evidence to ActionNurse‐led telephone‐based interventions focused on reducing glycosylated hemoglobin levels in people with type 2 diabetes can be used as an effective intervention to achieve glycemic control. We recommend holding an average of 15–25 min interviews once or twice a week.
