Strengths and limitations
One of the major advantages of this study is to determine which
knowledge patients lacked and the erroneous steps of insulin injection,
as well as related factors in order to shape the patient education and
target specific patients for education. However, some limitations should
be considered when interpreting the results. Firstly, KAP questionnaire
was focused only on insulin pen use, but not covered a broader domain in
treatment of diabetes. Secondly, patients in our study used only two
types of insulin pens (Insulin Aspart 70/30 and Insulin Glargine)
because of the hospital’s limited resources.
