Abstract Background An optimal cytomegalovirus (CMV) prevention strategy following solid organ transplantation (SOT) remains uncertain. This study reports on the rates of CMV events following a change in a local prevention guideline involving increased surveillance, earlier transition to oral valganciclovir, and decreased CMV‐immunoglobulin use. Methods A retrospective cohort study utilizing historical controls evaluated the rates of CMV invasive disease pre‐ and post‐intervention among pediatric heart, liver, and kidney recipients. Outcomes were recorded for the 4 years pre‐ and post‐intervention, 9/2009‐10/2017. Logistic regression was used to estimate the risk of a CMV event. Results There was no difference in the rates of CMV invasive disease between the two study groups ( P = 1). An increase in the detection of CMV events occurred ( P = .04), predominantly asymptomatic CMV infection. This increase was independently associated with increased surveillance testing among high‐risk heart and liver recipients, aOR 1.08 (1.06‐1.12). Surprisingly, 28.9% of CMV events occurred during antiviral prophylaxis. Conclusions Modification of the local CMV prevention guideline did not result in an increase in CMV invasive disease. CMV events occurred while on prophylaxis, highlighting a potential difference from adult solid organ transplant (SOT) and emphasizing the potential need for monitoring on prophylaxis in the pediatric population.
