Knowledge, attitude and practices of insulin therapy among patients with type 2 diabetes: a cross-sectional study

Abstract

ObjectivesThis study aimed to assess the knowledge, attitude and practices of patients with type 2 diabetes on insulin regarding insulin therapy.DesignA cross-sectional study.SettingThis study was conducted at the Dubai Diabetes Center from 1 December 2018 to 1 March 2020.ParticipantsFace-to-face interviews were conducted for 350 participants with type 2 diabetes at the Dubai Diabetes Center. Interviews followed the structured format of a questionnaire designed to obtain demographic details and score participants on knowledge, attitude and practices. We included patients aged >18 years and receiving insulin therapy. Patients with type 1 diabetes, pregnant women with gestational diabetes, those aged <18 years or those with a history of dementia were excluded.ResultsThe median age of participants was 61 years (first quartile, 53 years; third quartile, 67 years); 35.7% were male individuals and 64.3% were female individuals. The median percentage scores for knowledge, attitude and practices were 62.5% (62.5%, 75%), 85.7% (71.4%, 100%) and 77.7% (66.6%, 88.8%), respectively. Highly educated participants had a high level of knowledge. Significant negative correlations were found between the percentage knowledge scores and participants’ age and between the participants’ percentage attitude scores and haemoglobin A1C levels; Spearman’s correlations were −0.182 (p<0.001) and −0.14 (p=0.008), respectively. A significant positive Spearman’s correlation of 0.123 (p=0.021) was found between the percentage knowledge and percentage practice scores. No correlations were found among knowledge levels, participants’ haemoglobin A1c levels and duration of insulin use.ConclusionPatients with type 2 diabetes receiving insulin therapy and attending the Dubai Diabetes Center had adequate knowledge, a positive attitude and correct practice regarding insulin therapy. However, knowledge of specific facts did not always translate into correct behaviours and practices.
