Factors influencing insulin usage among type 2 diabetes mellitus patients: A study in Turkish primary care.

Background: DM (diabetes mellitus) patients with poorly regulated blood glucose levels are at risk of increased morbidity and mortality. There are different factors that cause resistance to the initiation of insulin therapy such as beliefs and perceptions concerning diabetes and its treatment and the nature and consequences of insulin therapy.

Objectives: We aimed to explore the reasons for this reluctance and how these obstacles could be overcome so that DM patients who require insulin could initiate therapy.

Methods: This was a cross-sectional, descriptive study of diabetic patients with glycated haemoglobin A (HbA) levels above 7.0%, who were followed-up at a primary care and endocrinology outpatient clinic.

Results: Ninety-four patients (57.4% females, 42.6% males) were recruited for this study. Most patients (57.4%) considered that insulin was a drug of last resort. Among all patients, 34.1% thought that insulin lowered blood glucose levels to an extreme degree and 14.9% disagreed. The patients thought that self-injection was hard (27.6%), required someone else to administer the injection (27.6%), insulin injection was painful (33.0%). 59.6% of all patients believed that their religion did not restrict the use of insulin, 52.1% stated that their family physicians had sufficiently informed them.

Conclusion: Our most significant finding is that a lack of adequate information relating to insulin appears to be the major factor behind DM patients' refusal of insulin treatment. The fact that patients consider insulin treatment as a final solution to DM could be related to resistance to the initiation of insulin therapy. [Box: see text].
