Evaluation of a Pharmacist-Developed, Nurse-Driven Protocol for Management of Parenteral Anticancer Therapy Infusion Reactions in an Ambulatory Infusion Center

Intravenous anticancer therapy can be associated with hypersensitivity- and/or infusion-related reactions (IRRs) which may result in life-threatening symptoms. As part of a quality improvement project, oncology pharmacists developed and implemented a nurse-driven, symptom-based IRR protocol. The objective of the evaluation was to evaluate IRR treatment failure after implementation of a symptom-based protocol in an ambulatory infusion center. Secondary objectives included determining the most common anticancer agents requiring IRR treatment, documentation of ED visits or hospital admissions within 72 h of treatment, documentation of mortality due to an IRR, and evaluating whether there were multiple documented IRRs to the same medication.A total of 456 patients, who received an infusion of anticancer therapy at Grady Health System (GHS) between February 2014 and March 2018, were retrospectively evaluated. Patients were included if they received a protocol-specific medication for infusion reaction management of a parenterally administered anticancer agent. The primary outcome was the rate of treatment failure within 72 h of treatment for an IRR.Seventy-eight patients experiencing 108 IRRs were included in the analysis. Five percent of IRRs consisted of rigors only, 57% of IRRs were mild/moderate severity, 31% of IRRs were severe/anaphylactic severity and 7% of IRRs were rigors in addition to a mild/moderate/severe reaction. Of the 108 IRRs, treatment failure within 72 h was observed in eight reactions; six were evaluated in the emergency department and two required a hospital admission. Overall, 93% of reactions resolved in the infusion center and patients were discharged home; there were no patient deaths. The most common offending agents were paclitaxel and oxaliplatin.Following implementation of a novel pharmacist-developed, symptom-based nurse-driven protocol, infusion reaction treatment failure occurred in 7% of IRRs evaluated. Although the failure rate was low, additional nurse education and improved access to protocol-directed medications may optimize use of the protocol.
