Knowledge, attitude and practice towards insulin self-administration and associated factors among diabetic patients at Zewditu Memorial Hospital, Ethiopia

BACKGROUND: Diabetes mellitus is a common health problem worldwide. Proper insulin administration plays an important role in long term optimal blood sugar control. Adequate knowledge and attitude about insulin self-administration could also improve the management of diabetes and eventually improve the quality of life. This study aimed to assess knowledge, attitude and practice towards insulin self-administration and associated factors among diabetic patients at Zewditu Memorial Hospital (ZMH), Ethiopia. METHODS: An institution-based cross-sectional study was conducted among 245 diabetic patients who were selected by systematic random sampling during follow-up at ZMH. The data was collected using an interviewer-administered structured questionnaire and analyzed by SPSS v.20. Binary logistic regression was used to identify associated factors of patients’ knowledge and P < 0.05 was used to declare the association. RESULTS: Among 245 patients enrolled, 53.9% were male with a mean age of 53.26 ±13.43 years and more than 84% of the patients can read and write. The overall patients’ knowledge was 63.4%. Better knowledge was observed concerning timing (78.4%) and site of insulin injection (89.4%), while knowledge on the angle of inclination during insulin administration (43.3%) and complications of insulin therapy (49%) were low. Patients who were male gender, never married, government or NGO employees, urban residents, who completed elementary and higher education had a higher knowledge than their comparators. The majority (62%) of the study patients had a favorable attitude on insulin self-administration. Although the majority 177(72.2%) of the study patients have administered insulin themselves, only 120(49.0%) of the patients injected insulin appropriately at 45(0). Frequent repetition of the injection site was practiced among 176(71.8%) patients and 139(56.7%) injected insulin before or immediately after food intake. CONCLUSION: Patients’ knowledge and attitude seem suboptimal and malpractice of insulin self-administration was reported. Therefore, the gaps should be addressed through patient education and demonstration of insulin injection during each hospital visit.
