Objective To investigate the current status of case management for children with diabetes in 31 provinces regions,and to provide references for the construction of case management model for children with diabetes. Methods Using convenient sampling,a self-designed electronic questionnaire was adopted to conduct across-sectional survey of nursing managers and diabetes nurses from 89 hospitals in 31 provinces of China from May 16 to May 31,2019. Results A total of 28 children’s hospitals,49 general hospitals and 12 maternal and child health care institutions were investigated. Among them,23 hospitals(25.84%) carried out case management for children with diabetes. However,among the 178 respondents,only 124(69.66%) were aware of case management. The implementation rales of pediatric diabetes case management in children’s hospitals and tertiary hospitals were better than those in non-children-specialized hospitals and secondary hospitals. The top 3 reasons why hospitals did not develop case management for diabetic children included the little knowing about case management among relevant professional personnel,imperfection of operation system and the shortage of staff. Conclusion Case management for diabetic children is far beyond fully covered in domestic hospitals. Taking full advantage of children’s hospitals and tertiary hospitals will facilitate the establishment of standardized work procedures and effective evaluation system,in order to provide high-quality services for diabetic children.
