Clinical characteristics and influencing factors of hypoglycemia in hospitalized patients with type 2 diabetes mellitus: A cross‐sectional study

AIM: Analysed clinical characteristics and influencing factors for hypoglycemia in hospitalized patients with type 2 diabetes mellitus (T2DM), and providing a scientific reference for precision nursing care of hypoglycemia in hospitalized patients with T2DM. DESIGN: A cross‐sectional study. METHODS: This study involved 378 hospitalized patients diagnosed with T2DM who have suffered hypoglycemia. Through questionnaires and electronic medical records to obtain the data concerning the general information, clinical symptoms, all recorded blood glucose information, and the diabetes knowledge and self‐management level of the patients. The clinical characteristics and influencing factors for hypoglycemia were analysed on the basis of the classification of hypoglycemia published by the American Diabetes Association in 2020. RESULTS: Among 378 patients, 207 patients (54.76%) were experiencing Grade 1 hypoglycemia and 171 patients (45.24%) were experiencing Grade 2 hypoglycemia. Hypoglycemia and Grade 2 hypoglycemia in patients with T2DM occurred predominantly within the first 3 days of hospitalization. Hypoglycemia occurred most frequently after breakfast (74 cases, 19.6%), of which Grade 1 hypoglycemia and Grade 2 hypoglycemia accounted for 50%, respectively. Multivariable logistic regression identified risk factors for Grade 2 hypoglycemia in hospitalized patients with type 2 diabetes: older age, longer duration of diabetes, low body weight, diabetic nephropathy stages 4–5, diabetic autonomic neuropathy, inadequate self‐management ability and diabetes knowledge, and lower educational background. CONCLUSIONS: Hypoglycemia in type 2 diabetes occurs in the first 3 days during the hospitalization and most often after breakfast during the full day. Identifying high‐risk individuals and providing a scientific reference for precision nursing care of hypoglycemia in hospitalized patients with T2DM.
