The process of diagnosis and linkage to care in cases of hepatitis C virus (HCV) infection remains an obstacle to disease control. The aims of this study were to evaluate predictive factors for not undergoing RNA testing among patients with positive HCV serology and impact of incorporating an automated electronic alert with recommendations in clinical practice. We collected HCV antibody tests requested from October 2011 to September 2014 to evaluate the rate of RNA testing and predictive factors for not undergoing RNA testing. Since October 2014, an automated alert notification has been implemented to remind physicians for testing RNA after a positive HCV test and referral to specialist care. 41 403 HCV antibody tests were requested from 34 073 patients. 870 (2.55%) patients tested positive. After a median of follow‐up of 57.0 months (range 45.6‐82.1), 37.6% did not have RNA testing. The independent predictors for not undergoing RNA testing were primary care serology requests ( P < 0.001), no history of drug use ( P = 0.005) and a lack of social support ( P = 0.015). The intervention impact was evaluated in a pre‐alert cohort (October 2011‐September 2014) and a post‐alert cohort (October 2014‐September 2015). After the incorporation of the alert, the rate of RNA testing increased from 62.4% to 77.7% ( P < 0.001). Incomplete assessment of HCV infection is a challenge in primary care. The implementation of an automated alert for recommending RNA testing after a positive HCV antibody test is feasible in clinical practice and increases the rate of patients with RNA testing.
