Cross-sectional study on knowledge of chronic kidney disease among medical outpatient clinic patients

Chronic kidney disease (CKD) is a major health concern worldwide. There are limited studies which look into the actual knowledge level of CKD among the general population both locally and internationally. This study aims to assess the knowledge level of CKD among patients in a secondary hospital in Malaysia.

Consecutive sampling of patients attending the Medical Outpatient Clinic was performed in this crosssectional study. Respondents were given self-administered questionnaires which contain questions on demographic characteristics and knowledge on CKD.

Out of 300 respondents, 78.6% (n=236) of the respondents completed the questionnaire. Majority of respondents (73.7%, n=174) scored less than 4 out of 7 marks on knowledge on CKD. Respondents who were younger, males, having higher education status, professionals/executives and earned higher monthly income were more likely to have a higher mean knowledge score of CKD. Respondents who have heard of CKD were also significantly associated with higher mean knowledge score of CKD.

The study findings suggest that our Malaysian population is still inadequately informed on CKD, especially those who are at risk of developing CKD and its complications, and also among those of the lower socioeconomic group. In order for successful primary and secondary prevention of CKD, more importance should be placed on increasing awareness on CKD among these atrisk groups.
