Abstract
This article describes the implications of shortages of pharmaceutical products used in conditioning and supportive care regimens of pediatric patients undergoing a hematopoietic stem cell transplantation in a tertiary care hospital. Between July 2011 and July 2016, a total of 84 individual shortages, affecting 22 different drugs (79.8% supportive care drugs; 20.2% chemotherapeutics) were detected with a mean duration of 85 days (SD 138) per individual drug shortage. Eighteen shortages were critical and very urgent. Sulfamethoxazol/trimethoprim, piperacillin/tazobactam, ranitidine, benzylpenicillin, ondansetron (supportive care) and methotrexate, melphalan (chemotherapeutics) had the longest supply disruptions. A variety of solutions could be identified including the purchase of a generic alternative (36.9%) for both oral and parenteral treatments (in a ratio 3:2). Urgent import from another (European) country was performed in 14 cases (16.7%). High impact solutions such as cohorting of patients and change of ongoing treatments (2.4%) were used for parenteral treatments only. Pharmaceutical modification was sometimes applied for oral treatments (2.4%). Due to persistent occurrence of these shortages, an efficient pharmacy workflow (electronic follow-up by end of 2016) and a multidisciplinary approach were needed.
