Effectiveness of telepharmacy diabetes services: A systematic review and meta-analysis

摘要

Purpose. Although pharmacist-provided diabetes services have been shown to be effective, the effectiveness of telepharmacy (TP) in diabetes management has not been clearly established. This systematic review and meta-analysis aims to evaluate the effectiveness of diabetes TP services. Methods. PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched (from inception through September 2021) to identify published studies that evaluated the effect of TP services in patients with diabetes mellitus and reported either glycosylated hemoglobin (HbA(1c)) or fasting blood glucose (FBG) outcomes. Mean difference (MD), weighted mean difference (WMD), relative risk (RR), and 95 confidence intervals were calculated using the DerSimonian and Laird random-effects model. Results. 36 studies involving 13,773 patients were included in the systematic review, and 23 studies were included in the meta-analysis. TP was associated with a statistically significant decrease in HbA(1c) (MD, -1.26; 95 CI, -1.69 to -0.84) from baseline. FBG was not significantly affected (MD, -25.32 mg/dL; 95 CI, -57.62 to 6.98). Compared to non-TP service, TP was associated with a lower risk of hypoglycemia (RR, 0.48; 95 CI, 0.30-0.76). In a subset of studies that compared TP to face-to-face (FTF) pharmacy services, no significant difference in HbA(1c) lowering was seen between the 2 groups (WMD, -0.09; 95 CI, -1.07 to 0.90). Conclusion. Use of TP was associated with reduction of HbA(1c) and the risk of hypoglycemia in patients with diabetes mellitus. High-quality randomized controlled trials are needed to validate the effectiveness of diabetes TP services relative to FTF services.
