The prescription rates of glucagon for hypoglycemia by pediatricians and physicians are low in Japan.

PURPOSE: Hypoglycemia is a common and life-threatening complication in type 1 diabetes mellitus (T1DM) patients. Current guidelines recommend glucagon for treating hypoglycemia in out-of-hospital settings; however, glucagon is reportedly underused in such patients. We conducted a doctor-oriented, questionnaire-based survey of pediatricians and physicians to determine the glucagon prescription rate and identify the reason(s) for its underuse in T1DM patients.

METHODS

A questionnaire was mailed to 415 pediatricians and 200 physicians employed at 66 facilities with >100 general wards throughout Hyogo, Japan. The following variables were surveyed: doctor's specialty, glucagon prescription rate, familiarity with glucagon use guidelines, barriers to prescribing glucagon, and attitude changes after education.

RESULTS

After 16 doctors were found to have retired, 599 doctors were enrolled; 305 (187 pediatricians and 118 physicians) returned a completed questionnaire. In all, 45 pediatricians and 104 physicians were treating T1DM patients, of whom 24% and 28% reported prescribing glucagon, respectively. The guideline familiarity rate among pediatricians was lower than that among physicians. The major barrier to prescribing glucagon was the complex preparation procedure required by patients/caregivers. More than half of the doctors who did not prescribe glucagon began doing so after being educated about the guidelines.

CONCLUSION

The glucagon prescription rate was low among both pediatricians and physicians in Japan.
