Knowledge and competence of primary healthcare physicians in the management of diabetes-related chronic kidney disease

Background: Diabetes mellitus (DM) is a primary cause of chronic kidney disease (CKD), a significant and growing global health issue. Primary healthcare physicians (PHPs) are crucial in detecting, managing, and preventing CKD, but many lack the necessary knowledge and skills to effectively diagnose and manage the disease. This study assessed the knowledge and competence of PHPs in managing diabetes-related CKD.

Materials and methods: This cross-sectional study was conducted among all Primary Healthcare Physicians (PHPs) working at Primary Healthcare Center (PHC) in King Abdulaziz Medical City of the National Guard, Jeddah, Saudi Arabia. An online questionnaire was sent to all PHPs and data were collected from January 2024 to February 2024. Data analysis performed utilizing RStudio (version 4.3.1). Categorical variables were expressed as frequencies and percentages, whereas mean and standard deviations were computed for continuous variables. Kruskal-Wallis rank sum test was used to determine differences in confidence scores across various demographic and occupational characteristics. A multivariable linear regression analysis was performed to identify factors related to confidence.

Results: Of 141 PHPs, 122 filled online questionnaire yielding a response rate of 86.5%. responded. The majority (90.2%) were 18-45 years of age, 68.0% were qualified as family physicians, 38.0% belonged to the specialized poly clinic, and 54.9% had less than 5 years of experience. PHPs showed a varied levels of confidence and knowledge. While 76.2% were confident about the stages of kidney disease and 65.6% acknowledged the importance of the urine albumin-creatinine ratio (uACR) test, 58.1% were uncertain of interpreting uACR results and CKD diagnostic criteria. More than 60.0% were uncertain of the treatment steps postdiagnosis and prediction of CKD prognosis. Age, qualification, specialization in family medicine, and clinic affiliation were significantly related to confidence levels.

Conclusion: The study underscores notable gaps in PHPs' knowledge and confidence concerning CKD screening, diagnosis, and management. Continuous education and targeted interventions are essential for the improvement of PHPs' competence and patient outcomes in the management of CKD.
