Improving vaccine administration in patients with solid malignancies in the outpatient setting.

Abstract

194 Background: Pneumococcal and influenza vaccinations are recommended for all patients with any malignancy in accordance with the Infectious Disease Society of America. Patients undergoing chemotherapy for solid tumors have a 40-50 fold higher risk for the development of invasive pneumococcal disease compared to healthy adults with a case fatality rate of 35% and should receive the sequential 13-valent pneumococcal conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPSV23). In the outpatient setting, lack of provider knowledge, complexity of the pneumococcal vaccine regimen and disruption in work-flow of a busy clinic can lead to low rates of administration. Towards this end, we conducted a quality project to improve administration of both pneumococcal and influenza vaccines by at least 50% at one of our outpatient oncology clinics at Montefiore Medical Center in Bronx, NY during a 4 month period. Methods: We first provided provider and nursing education with regard to safety and efficacy of the vaccines in both the clinic as well as the infusion setting. Nurses were then prompted to screen patients and offer the vaccines during intake prior to all infusions and clinic visits. We created bulk orders which allowed nurses greater control of releasing vaccine orders previously entered by the director of the clinic. We also posted “cheat-sheets” on optimal timing, safety and sequence of administration of the vaccines in every patient room and nursing station. After our first cycle, we identified that there was a delay in work-flow in the outpatient clinic with delivery of the vaccines to the clinic from the pharmacy. We therefore obtained a secure vaccine fridge that was placed at the nursing station, which allowed nurses easy access to the vaccines. Results: When vaccine administration during the 2018-2019 influenza season was compared to the 2019-2020 influenza season, we found that these interventions improved the administration of the influenza vaccine by 70%. There was a dramatic increase in the number of PCV-13 vaccines administered by 350% (more than 5-fold) and increase in PPVS-23 by 12.5%. No immediate adverse reactions during this cycle were reported to our nurse manager. Conclusions: A simple intervention of improved work-flow of vaccine administration and increased education of providers and nurses translated to a dramatic improvement in the administration of influenza and PCV-13 vaccines in a busy outpatient oncology clinic.
