Out-of-Hospital Management of Diabetic Emergencies in Germany: Structural and Process Quality.

AIMS: To collect and analyse representative data of structural and process quality in the management of diabetic emergencies in Germany in 2020. METHODS: A standardised questionnaire comprising detailed items concerning clinically relevant parameters on the structural and process quality of out-of-hospital management of diabetic emergencies was sent nationwide to medical directors of emergency medical service districts (EMSDs). Results were compared with those from a similar study conducted in 2001. RESULTS: The return rate of the questionnaires represented 126 EMSDs, serving a total population of > 40.1 million. Only 4% of ambulances carried glucagon (6% in 2001). In 2020, blood glucose determination increased significantly to 71% of all emergency interventions and to 29% of suspected cardiac emergencies (24% and 15%, respectively, in 2001). In 100% of EMSDs severe hypoglycaemia (SH) was treated by paramedics by administering intravenous dextrose before the arrival of a doctor compared to 63% in 2001. The potential value of nasal glucagon was acknowledged by 43% of responders. In selected patients, treatment of SH was conducted without hospital admission in 78% of EMDs (60% in 2001). Fifty-three percent of medical directors acknowledged the need for further training in diabetic emergencies (47% in 2001). Cooperation for medical education between emergency teams and a diabetes centre was reported by 14% (41% in 2001). CONCLUSION: Structural and process quality of the management of diabetic emergencies in Germany has improved considerably since 2001. Persisting deficiencies could be improved by providing better medical equipment in ambulances and ongoing education to the entire emergency teams.

Accumulation of severe hypoglycemia at weekends and in warm seasons in patients with type 1 diabetes but not with type 2 diabetes.

AIMS: To determine the influence of daytime, weekdays and seasons on the frequency of severe hypoglycemia (SH) in a German population. METHODS: Prospective population-based observational study capturing all episodes of SH between 2007 and 2014 in the Lippe-Detmold area. SH was defined as a symptomatic event requiring treatment with intravenous glucose or administration of glucagon and being confirmed by a blood glucose measurement of <2.8mmol/l. RESULTS: A total of 1080 episodes of SH in 747 patients were registered. 37.5% of cases (405/1080) were related to T1DM, 51.9% (561/1080) to T2DM, 3.2% (35/1080) to pancreatic diabetes and 7.3% (79/1080) to non-diabetic individuals. In cases with T1DM we observed a significantly higher event rate of SH at weekends versus the rest of the week: 2.87 events/weekend-hour versus 2.15 events/weekday-hour (p=0.004), especially on Saturdays. We found significantly increased incidences of SH in spring (31.2%) and summer (26.7%) versus autumn (20.3%) and winter (21.8%). There were no corresponding significant seasonal variations of HbA1c and insulin doses. The seasonal distribution of SH in subjects with T2DM was balanced with no peak incidence at weekends. CONCLUSIONS: For the risk of SH, time factors appear to contribute more substantially in individuals with T1DM than in patients with T2DM. The enhanced frequency of SH in patients with T1DM at weekends and in warm seasons was probably caused by short-term changes in behavior. Intensification of diabetes care and education with better adjustment of insulin doses in these susceptible periods could be an appropriate approach to prevent SH.

Substantial increase in incidence of severe hypoglycemia between 1997-2000 and 2007-2010: a German longitudinal population-based study.

OBJECTIVE: To compare the incidences of severe hypoglycemia and corresponding clinical circumstances in a German population between 2007-2010 and 1997-2000. RESEARCH DESIGN AND METHODS: A screening for severe hypoglycemia was performed in the Lippe-Detmold area in Germany to sensitively detect severe hypoglycemia. This was defined as a symptomatic event requiring treatment with intravenous glucose and being confirmed by a blood glucose measurement of <50 mg/dL. RESULTS: Severe hypoglycemia increased considerably from 264 events in 1997-2000 to 495 events in 2007-2010, which translated into an increase in frequency of severe hypoglycemia among all emergency admissions from 0.68 to 0.83% (P = 0.015). This was mostly related to intensification of antihyperglycemic therapy, particularly in the increasingly morbid group of hypoglycemic patients with type 2 diabetes indicated by lower HbA(1c), more comedication (3.3 vs. 7.7 drugs), and more concomitant diseases (3.6 vs. 4.4) (all P values <0.001). CONCLUSIONS: Within a 10-year period, there was an intensification of antihyperglycemic therapy in increasingly comorbid subjects, leading to a considerably higher incidence of severe hypoglycemia.
