Objectives: This study aimed to identify the main barriers which prevent patients with diabetes mellitus from accepting insulin therapy. Methods: This cross-sectional study was conducted from May to December, 2019. Convenience sampling was used to recruit participants from three Diabetes Clinics in Muscat. Eligible participants were interviewed in person based on a pre-prepared questionnaire. The questionnaire, which was administered in Arabic, includes demographic data, and 19 specific items on barriers to insulin therapy. Results: A total of 201 participants (response rate 93 %) were enrolled in the study. The commonest barriers were as follows: concern of frequent blood glucose checking (36.3%), long- term injections (33.8%), side-effects of insulin (29.9%), and weight gain (29.4%). Needle phobia was considered as a barrier by only 9% of the participants. Overall, 125 (62.2%) of the participants were willing to initiate insulin therapy despite of the presence of these barriers and only 20 (10%) of the participants were influenced by these barriers to the degree that they would reject insulin therapy. Conclusion: The majority of our participants had no identifiable reasons which would stop them from accepting insulin therapy. Effective strategies should be developed to address each of the main barriers to improve acceptance and adherence to insulin therapy.
