the headwind study - part 2

Conditions: Diabetes; Diabetes Mellitus, Type 1

Summary: to analyse driving behavior of individuals with type 1 diabetes in eu- and progressive hypoglycaemia while driving in a real car. based on the driving variables provided by the car the investigators aim at establishing algorithms capable of discriminating eu- and hypoglycemic driving patterns using machine learning neural networks (deep machine learning classifiers).

hypoglycaemia is among the most relevant acute complications of diabetes mellitus. during hypoglycaemia physical, psychomotor, executive and cognitive function significantly deteriorate. these are important prerequisites for safe driving. accordingly, hypoglycaemia has consistently been shown to be associated with an increased risk of driving accidents and is, therefore, regarded as one of the relevant factors in traffic safety. despite important developments in the field of diabetes technology, the problem of hypoglycaemia during driving persists. automotive technology is highly dynamic, and fully autonomous driving might, in the end, resolve the issue of hypoglycemia-induced accidents. however, autonomous driving (level 4 or 5) is likely to be broadly available only to a substantially later time point than previously thought due to increasing concerns of safety associated with this technology. therefore, solutions bridging the upcoming period by more rapidly and directly addressing the problem of hypoglycemia-associated traffic incidents are urgently needed. on the supposition that driving behaviour differs significantly between euglycaemic state and hypoglycaemic state, the investigators assume that different driving patterns in hypoglycemia compared to euglycemia can be used to generate hypoglycemia detection models using machine learning neural networks (deep machine learning classifiers).

Eligibility criteria:
inclusion criteria: * informed consent as documented by signature * type 1 diabetes mellitus as defined by who for at least 1 year or confirmed c-peptide negative (\ 4 mmol/l) * age between 21-60 years * hba1c ≤ 9.0 % * functional insulin treatment with good knowledge of insulin self- management * passed driver's examination at least 3 years before study inclusion. possession of a valid, definitive swiss driver's license. * active driving in the last 6 months. exclusion criteria: * contraindications to the drug used to induce hypoglycaemia (insulin aspart), known hypersensitivity or allergy to the adhesive patch used to attach the glucose sensor. * pregnancy or intention to become pregnant during the course of the study, lactating women or lack of safe contraception * other clinically significant concomitant disease states as judged by the investigator * physical or psychological disease likely to interfere with the normal conduct of the study and interpretation of the study results as judged by the investigator * renal failure * hepatic dysfunction * coronary heart disease * other cardiovascular disease * epilepsy * drug or alcohol abuse * inability to follow the procedures of the study, e.g. due to language problems, psychological disorders, dementia, etc. of the participant * participation in another study with an investigational drug within the 30 days preceding and during the present study * total daily insulin dose \>2 iu/kg/day * specific concomitant therapy washout requirements prior to and/or during study participation * current treatment with drugs known to interfere with metabolism or driving performance
