Optimizing influenza vaccination among oncology patients through quality improvement cycles.

285 Background: Influenza poses significant risks to cancer patients, who are especially vulnerable due to immunosuppression caused by both their disease and treatment. (Cooksley et al., 2005) Sidney Kimmel Cancer Center – Jefferson Health (SKCC)’s Quality Improvement (QI) initiative aimed to increase influenza vaccination rates among adult cancer patients in our Center City clinic from October 2023 to March 2024. At baseline in the 2022-2023 flu season, 49% of our patients had a documented vaccination against influenza, leaving most of our patient population at increased risk for influenza infection. Methods: A series of four Plan-Do-Study-Act (PDSA) cycles were implemented over the course of the vaccination season. Cycle 1 collected baseline data on vaccination status via electronic health records (EHRs) and identified gaps in patient knowledge and vaccine hesitancy. Cycle 2 trained medical assistants (MAs) to engage in effective vaccination conversations, emphasizing the use of presumptive communication techniques and the reconciliation of immunization records in EHRs. Cycle 3 integrated patient education materials on vaccination in the clinical encounter. Cycle 4 scaled assessment protocols across teams. Results: Cumulatively, 68% (2,592/3,824) of unique oncology patients had a documented influenza vaccination by the completion of the season in March 2024. Integration of vaccine reconciliation into the MA workflow was the iteration that led to the biggest increase in vaccination rate among the PDSA cycles tested. We surpassed our initial aim for the season (59%) in this metric. Conclusions: The QI project at SKCC demonstrates that layered strategies involving both patients and care teams can improve vaccination rates among adult cancer patients. Integration of vaccine assessment into clinic workflows was an effective tactic. Future efforts will focus on replicating these successes with other vaccines.
