Improving flu vaccination rates among adult patients with cancer at Kaiser Permanente.

326 Background: Vaccines protect cancer patients from developing severe illness, hospitalization, and death. At Kaiser Permanente (KP) South Sacramento Medical Center (KPSSC), oncology patients on active chemotherapy had an overall flu vaccination rate of 13% between September 1, 2022, and December 1, 2022. Our aim was to increase this rate to 33% during the 2023 flu season. Methods: In conjunction with the ASCO Quality Training Program, we applied quality improvement initiatives to improve flu vaccination. Our population of interest included adult cancer patients on active chemotherapy at KPSCC. We evaluated the barriers to vaccination assessment by distributing surveys to infusion nurses. We performed three Plan-Do-Study-Act (PDSA) cycles for quality improvement and monitored flu vaccination rates. Cycle 1 (9/11/2023 to 11/5/2023): We distributed the ASCO flu vaccine handout at oncology clinic. We had medical assistants and infusion nurses administer flu vaccines during clinic visits and chemotherapy sessions. Cycle 2 (11/6/2023 to 11/21/2023): We added the vaccine handout in Chinese and Spanish and updated our receptionists’ script to strongly encourage patients to receive flu vaccine. Cycle 3 (11/22/2023 to 12/6/2023): KP flu clinic set up an onsite flu vaccine cart one half day per week in the oncology clinic. Results: Barriers to vaccination assessment in the clinic included lack of time (60%), difficulty remembering to ask (10%), and non-influenza season (10%). Our interventions resulted in an increased flu vaccination rate from 13% in 2022 to 36% in 2023. During cycle 1, 298 out of 615 patients received their vaccine (48.5%). During cycle 2, 16 out of 118 patients received their vaccine (13.6%). PDSA cycle 3 resulted in 14 out of 178 patients receiving their vaccine (7.9%). Conclusions: Promoting vaccine awareness via active engagement with nurses and medical assistants early on and having onsite vaccine availability in the oncology clinic were keys to improve the overall flu vaccination rate. While most vaccines were administered at the beginning of flu season, the addition of language-tailored vaccine handouts and having an onsite vaccine cart towards the end of the season did result in late season vaccinations. Our findings do support the importance of providing timely vaccine information in the oncology clinic. Our future goal is to expand these efforts to other KP Northern California oncology centers to establish stable onsite vaccine availability in clinics and include additional vaccine types.
