Quality Improvement Interventions to Enhance Vaccine Uptake in Cancer Patients: A Systematic Review.

Abstract

Cancer patients, because of their compromised immune responses, face a higher risk of preventable infections, leading to increased morbidity and mortality. Despite this, vaccination rates among these patients are suboptimal, and research on effective interventions to improve vaccination rates is limited. We conducted a comprehensive search in PubMed and Cochrane Library for studies investigating quality improvement (QI) interventions targeting vaccine uptake in cancer patients. Two authors independently screened, extracted data, and analyzed studies, resolving any discrepancies through consensus. Thirteen studies met the inclusion criteria, published between 2014 and 2022. Seven studies focused on the influenza vaccine, five on the pneumococcal vaccine, and one on both. Twelve studies used multiple interventions, whereas one used a single intervention. Most interventions aimed to enhance patient and family knowledge and identify eligible patients before their appointments. All studies demonstrated improved vaccine uptake after implementing the interventions. A variety of QI interventions have effectively increased pneumococcal and influenza vaccine uptake among cancer patients. Future research should address roadblocks to implementation and explore the effect of these interventions on other vaccines.
