KNOWLEDGE, ATTITUDE AND FACTORS ASSOCIATED WITH SELF-EFFICACY IN SCREENING AND TREATMENT OF HEPATITIS C AMONG PRIMARY CARE DOCTORS IN SELANGOR Introduction: Primary care doctors (PCDs) play an increasingly important role in the management of hepatitis C. It is essential for PCDs to have good self-efficacy in screening and treating hepatitis C to achieve good outcomes. This study aimed to determine the knowledge and attitude towards andother factors associated with self-efficacy in screening and treating hepatitis C. Methods: This cross-sectional study was conducted using an online Google Form. PCDs workingat primary healthcare clinics were selected via simple random sampling. The online form contained items on sociodemographic and practice characteristics and a validated questionnaire on knowledge,attitude and self-efficacy towards screening and treating hepatitis C. Data were statistically analysed. Results: A total of 242 PCDs were included in the analysis. The median age was 35 years(interquartile range [IQR]=5). The majority of the PCDs were women (83.9%) and Malay (71.9%)and had a median working experience of 6 years (IQR=6). The mean self-efficacy score was 12.67(standard deviation=3.38). The factors associated with a higher level of self-efficacy in screening and treating hepatitis C were postgraduate qualification, training within the last one year, better knowledge and attitude scores and prior experience in treating hepatitis C. Conclusion: The identified factors are crucial in improving the self-efficacy among PCDs in hepatitis C care services. Policymakers are suggested to implement training programmes and encourage continuous medical education, exposure to patient management and postgraduate certification in family medicine to help PCDs in treating hepatitis C better.
