Insulin pen injection technique survey in patients with type 2 diabetes in mainland China in 2010

Abstract

The insulin injection skill of patients with diabetes in mainland China was poor, and the incidence of lipohypertrophy, bleeding, and needle reuse was high. Frequency of daily insulin injection and needle reuse may relate to the incidence of lipohypertrophy and bleeding. The bleeding and bruising at the injection sites may be associated with suboptimal absorption of injected insulin. Improved education in optimal insulin injection technique, including reducing needle reuse and correct rotation of injection sites should be emphasized.
