Diabetes knowledge among patients with type 2 diabetes at the University of Santo Tomas Hospital using the Filipino version of Michigan Diabetes Knowledge Test (Filipino-DKT)

ABSTRACT

@#<p style="text-align: justify;"><strong>Background:</strong> A well-informed patient with Type 2 diabetes may be more compliant with treatment. This study aims to evaluate the diabetes-related knowledge and socio demographic determinants of patients seen at University of Santo Tomas Hospital through a translated and validated Filipino-DKT questionnaire.</p><p style="text-align: justify;"><strong>Methods:</strong> Standard translation procedure was used to produce the Filipino version of the DKT2. A convenience sample of 112 outpatients with Type 2 diabetes was identified for six months at the University of Santo Tomas Hospital, Philippines. All data were collected using the Filipino-DKT and a demographic questionnaire.</p><p style="text-align: justify;"><strong>Results:</strong> The Filipino-DKT demonstrated an acceptable Cronbach's alpha of 0.70 and an acceptable average inter-item correlation of 0.40 (p<0.001). The test-retest reliability was excellent, with a Pearson coefficient r of 1.00 (p<0.001). Our study demonstrated that of the 112 patients with diabetes who answered the general knowledge test, the majority had average knowledge of 78.64%, while 16.07% had poor knowledge. A total of 55 participants on insulin answered the second part of Filipino-DKT that measures insulin knowledge. Surprisingly, 56% of the subjects on insulin had poor knowledge, and only 7% had good knowledge. Results showed that the majority (56%) had poor knowledge. Participants who reported poor control of their diabetes (HbA1c >7%) also reported lower levels of knowledge about diabetes and insulin use. There was no association between duration of diabetes, family history of diabetes, and type of diabetes with knowledge of diabetes.</p><p style="text-align: justify;"><strong>Conclusion:</strong> The Filipino diabetic knowledge of diabetes is poor and not related to age, sex, and duration of diabetes. Filipino-DKT is an acceptable, reliable, and valid measure of diabetes knowledge used in our clinical practice and research.</p>
