Objective To explore the concept of impaired hypoglycemic awareness in patients with diabetes mellitus and to provide theoretical basis for guiding clinical practice of medical staff and related research. Methods Publications related to impaired awareness of hypoglycemia were searched from CNKI, Wanfang Database, Web of Science, PubMed and EMbase,and Walker and Avant concept analysis method was used to analyze the concept of impaired awareness of hypoglycemia. Results A total of 35 publications were included.The defining attributes of impaired awareness of hypoglycemia were diabetic patients receiving insulin therapy, repeated exposure to hypoglycemia and decreased or vanishing awareness of hypoglycemia.The antecedents were general demographic factors, history of hypoglycemia, strict blood glucose control, anxiety and fear,etc.The outcomes were cognitive impairment, increased risk of cardiovascular events, and psychosocial burden.The concept was mainly assessed by the Gold Score, Clarke Scale, Pedersen Questionnaire and Hypoglycemia Awareness Questionnaire. Conclusion Concept analysis of impaired hypoglycemic awareness,enables correct understanding, prevention and cognition of the condition, which can provide reference for future research on impaired awareness of hypoglycemia.
