Knowledge and Management of Insulin Therapy in Patients with Diabetes in Primary Care: a Study in Russas, Ceará

This descriptive and quantitative study evaluated the knowledge and management of insulin therapy among 26 insulin-dependent patients at the Mutirão Primary Health Unit, Russas, Ceará, between March and April 2025. Using a structured questionnaire, sociodemographic, clinical, and insulin-related practices were characterized. A predominance of type 2 diabetes (92%) and elderly patients (69.23%) was observed, with only 12% distinguishing between rapid- and long-acting insulins. Insulin use was positively rated by 73.08%, but knowledge gaps (88.46% knew only the insulin they used) and inadequate practices, such as needle reuse (14 patients), indicate a need for health education. Adherence was high (84.62%), though 15.38% skipped doses. Multidisciplinary educational interventions, emphasizing the pharmacist’s role, are crucial to promote self-care, reduce complications, and improve clinical outcomes.
