End date September 2017
Trial size 100 participants
Trial identifier NCT02228642, PRO14030372


Patients with diabetes who develop low blood sugars (hypoglycemia) in the hospital are at risk for losing the ability to develop symptoms that warn them that they are having a low blood sugar. There is almost no available information investigating how the inability to feel symptoms of a low blood sugar contributes to the risk of this happening when people with diabetes are hospitalized. The purpose of this study is to develop a symptom score model that will help to identify patients at risk for low blood sugars in the hospital and to examine what happens to patients who do experience a low blood sugar in the hospital.

Additional Information

Official title A Prospective Investigation Into the Causes, Symptoms, and Outcomes in Patients With Diabetes Who Experience Hypoglycemia During Their Hospitalization
Principal investigator Mary T Korytkowski, MD
Description Patients who develop recurrent hypoglycemia are predisposed to developing hypoglycemia-associated autonomic failure (HAAF, impaired awareness). There is almost no information investigating the contribution of HAAF as a risk factor for hypoglycemia in hospitalized patients. Our central aim is to develop a validated inpatient hypoglycemic symptom score model to examine HAAF and its correlation with cognitive dysfunction, re-hospitalization rates, inpatient morbidity and mortality. This will be a prospective non-blinded study performed in a tertiary care center that will include non-critically insulin treated patients with Type 1 and 2 Diabetes. We will identify patients who have experienced moderate hypoglycemia (40-70 mg/dl) or severe hypoglycemia (< 40 mg/dl) within the prior 24 hours by daily generated computerized reports. Participants will be asked to complete a Hypoglycemia Symptom Scores Questionnaire and cognitive testing within 24-36 hours post event. Participants will be contacted at 6 and 12 months following the index hospitalization to obtain information regarding recurrent episodes of hypoglycemia, need for re-hospitalization, and occurrence of any new diabetes related complications.
