Effectiveness of Remotely Delivered Interventions to Simultaneously Optimize Management of Hypertension, Hyperglycemia and Dyslipidemia in People With Diabetes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background:& nbsp;Remotely delivered interventions may be more efficient in controlling multiple risk factors in people with diabetes.& nbsp;Purpose:& nbsp;To pool evidence from randomized controlled trials testing remote management interventions to simultaneously control blood pressure, blood glucose and lipids.& nbsp;Data Sources:& nbsp;PubMed/Medline, EMBASE, CINAHL and the Cochrane library were systematically searched for randomized controlled trials (RCTs) until 20(th) June 2021.& nbsp;Study Selection:& nbsp;Included RCTs were those that reported participant data on blood pressure, blood glucose, and lipid outcomes in response to a remotely delivered intervention.& nbsp;Data Extraction:& nbsp;Three authors extracted data using a predefined template. Primary outcomes were glycated hemoglobin (HbA1c), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), systolic and diastolic blood pressure (SBP & DBP). Risk of bias was assessed using the Cochrane collaboration RoB-2 tool. Meta-analyses are reported as standardized mean difference (SMD) with 95% confidence intervals (95%CI).
& nbsp;Data Synthesis:& nbsp;Twenty-seven RCTs reporting on 9100 participants (4581 intervention and 4519 usual care) were included. Components of the remote management interventions tested were identified as patient education, risk factor monitoring, coaching on monitoring, consultations, and pharmacological management. Comparator groups were typically face-to-face usual patient care. Remote management significantly reduced HbA1c (SMD -0.25, 95%CI -0.33 to -0.17, p < 0.001), TC (SMD -0.17, 95%CI -0.29 to -0.04, p < 0.0001), LDL-c (SMD -0.11, 95%CI -0.19 to -0.03, p=0.006), SBP (SMD -0.11, 95%CI -0.18 to -0.04, p=0.001) and DBP (SMD -0.09, 95%CI -0.16 to -0.02, p=0.02), with low to moderate heterogeneity (I-2= 0 to 75). Twelve trials had high risk of bias, 12 had some risk and three were at low risk of bias.& nbsp;Limitations:& nbsp;Heterogeneity and potential publication bias may limit applicability of findings.& nbsp;Conclusions:& nbsp;Remote management significantly improves control of modifiable risk factors.& nbsp;
