Class of 2012 Abstract / Specific Aims: To compare and evaluate the therapies prescribed, the incidence of adverse drug events, and the time to clinical cure in transplant patients with a cytomegalovirus (CMV) infection at an academic medical center before and during the foscarnet nationwide shortage.
Methods: This study was a retrospective chart review to compare CMV treatment prescribed and clinical outcomes in pediatric and adult transplant patients at an academic medical center. Transplant patients were evaluated over a 16 month time period between December 2009 and March 2011. The average dose (mg/kg) and prevalence ganciclovir, foscarnet, and cidofovir prescribed in transplant patients with CMV infection were evaluated. Additionally, the incidence of adverse drug events including acute renal dysfunction and myelosuppression were characterized. Main Results: There were 30 subjects diagnosed with CMV disease during the evalutaion period. Of all of the patients treated for CMV before the shortage, 79% received ganciclovir, 43% received foscarnet, and 21% received cidofovir. Following the shortage in September 2010, the usage of the antiviral agents changed to 100%, 25%, and 13% respectively. Overall the usage of ganciclovir increased while the usage of foscarnet decreased when there was a shortage of medication.
Conclusions: The antiviral prescribing patterns changed significantly during the foscarnet shortage. The average dose and incidence of ganciclovir increased which likely contributed to serious adverse events. Due to the limited amount of patients treated for CMV and the short time frame, clinical cure could not be determined at this time. Drug shortages are a serious problem and significantly influence patient outcomes.
