In the 45 participants using ADTs, the BGAT and HARPdoc interventions both reduced SH incidence by more than 50% (P<0.0001) and yielded improvements in hypoglycemia awareness (P<0.05). HARPdoc outperformed BGAT in reducing SH at month 24 (P=0.01). HARPdoc also mitigated unhelpful hypoglycemia beliefs (P<0.0001), diabetes distress (P<0.05), and anxiety symptoms (P<0.05); BGAT demonstrated no significant impacts in these respects. Neither HARPdoc nor BGAT had significant effects on depression symptoms.

Data from trial participants who utilized ADTs including continuous glucose monitors or automated insulin delivery systems were extracted. Generalized linear mixed effects models with Poisson distribution or linear mixed effects models were employed to evaluate SH incidence, and Gold questionnaire, Attitudes to Awareness of Hypoglycemia (A2A), Problem Areas in Diabetes (PAID), Hospital Anxiety and Depress Scale (HADS)-anxiety, and HADS-depression scores as measures of hypoglycemia awareness, unhelpful hypoglycemia beliefs, diabetes distress, and anxiety and depression symptoms, respectively.

A subgroup analysis of the Hypoglycemia Awareness Restoration Programme for people with type 1 diabetes and problematic hypoglycemia (HARPdoc) trial was conducted to explore the impact of Blood Glucose Awareness Training (BGAT, a hypoglycemia awareness training program) and the HARPdoc (a psychoeducation addressing unhelpful hypoglycemia beliefs) in reducing severe hypoglycemia (SH) in individuals using advanced diabetes technologies (ADTs).

Psychoeducation (BGAT and HARPdoc) was effective in reducing SH in people using ADTs. HARPdoc may also provide greater long-term SH reduction and improves psychological wellbeing in this patient group.
