Clinical impact of the etoposide injection shortage

Drug shortages have become a constant challenge in patient care over the past two decades. In 2018, there was a shortage of etoposide injection in the United States. The purpose of this study was to analyze the impact of the etoposide injection shortage.

This single-center, retrospective chart review included patients prescribed an etoposide-containing chemotherapy regimen between January 2018 and August 2018. The primary objective was to determine the percentage of patients who required a change in treatment due to the etoposide injection drug shortage. For the secondary objectives, the following was compared between patients who received etoposide injection versus alternative etoposide formulations (etopophos injection or oral etoposide): adverse events, medication errors, treatment delays, disease progression, and drug costs.

Twenty-two patients were included in this study. Overall, seven (32%) patients required a change in treatment due to the etoposide injection shortage. Of the seven patients, six required the use of an alternative etoposide formulation and one patient had etoposide omitted in at least one treatment cycle. There were no significant differences in adverse events, medication errors, treatment delays, or disease progression when comparing patients who received etoposide injection versus alternative etoposide formulations. The average drug cost per cycle was significantly higher in the patients who required a change in treatment.

To our knowledge, this is the first study to characterize the clinical impact of the etoposide injection shortage. Results from this study highlight the direct impact that drug shortages have on patient care.
