Abstract

OBJECTIVE: To establish the effectiveness of a brief, partly web-based group intervention, HypoAware, in patients with problematic hypoglycemia, in terms of the reduction of severe hypoglycemic episodes, impaired hypoglycemia awareness, and worries. RESEARCH DESIGN AND METHODS: A two-arm, cluster randomized controlled trial was conducted in insulin-treated patients with problematic hypoglycemia in eight Dutch clinics comparing HypoAware with care as usual. Primary outcomes included self-reported severe hypoglycemia, impaired hypoglycemia awareness (Gold score), and worries and distress about hypoglycemia (Hypoglycemia Fear Survey-II/Problem Areas In Diabetes scale hypo-item), assessed at baseline, and at 2, 4, and 6 months of follow-up. We used t tests, nonparametric tests, and intention-to-treat generalized estimation equation (GEE) analyses with linear, logistic, and Poisson or negative binomial models. RESULTS: We enrolled 137 participants. Adjusted GEE analyses over four time points showed a nonsignificant 33% fewer episodes of severe hypoglycemia in the HypoAware group compared with the control group (relative risk [RR] 0.67 [95% CI 0.39–1.16], P = 0.150); a significant reduced odds of impaired awareness (odds ratio 0.38 [95% CI 0.15–0.95], P = 0.038), a trend toward 20% fewer worries about hypoglycemia (RR 0.80 [95% CI 0.64–1.01], P = 0.059), and a significant 30% less hypo-distress (RR 0.70 [95% CI 0.56–0.88], P = 0.002). Over the 6-month study duration, participants experienced a median of 2.5 events of severe hypoglycemia (interquartile range [IQR] 1–10) in the control condition versus 1 event (IQR 0–6.5) in the HypoAware group (P = 0.030). There was no significant change in HbA1c level within and between both groups. CONCLUSIONS: HypoAware resulted in fewer severe hypoglycemic episodes, significantly improved hypoglycemia awareness, and less hypo-distress in comparison with usual care, and deserves further dissemination.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
