HealthTree Patient Portal mediated myeloma patient-reported vaccination and antibiotic use.

Abstract

e20567 Background: Multiple myeloma (MM) is a cancer of the immune system. Infection is a major cause of morbidity and mortality in MM. Vaccines are the first line of prevention for infectious diseases. Anti-microbial prophylaxis may improve patient (pt) outcomes, but real-world use has not been well characterized. In order to engage the pt community regarding vaccination we utilized HealthTree (www.healthtree.org). Methods: An investigator-submitted online survey asking about infection prophylaxis and vaccinations was fielded to 4,944 pts from May 10, 2019, to January 9, 2020. The HealthTree platform queries pts about sharing data for research purposes. De-identified responses were aggregated and reviewed. The study was determined to be exempt by the Western Institutional Review Board. Results: 458 MM pts participated in the surveys and were able to select more than one option with the total response indicated below. Abbreviated questions and simplified responses are noted in Table including: 1. Have you ever been vaccinated in the last 5 years with a pneumococcal vaccine (PV)? 2. In the last 3 flu seasons, have you received the influenza vaccine (FV)? 3. After you began myeloma treatment, did you ever receive the anti-Varicella Zoster Virus (VZV, shingles) vaccine? 4. Were you (or are you currently) treated with anti-viral prophylaxis? 5. Were you (or are you currently) treated with antibiotic bactrim? 6. Were you (or are you currently) treated with levofloxacin prior to stem cell transplant or at the beginning of your MM therapy? Conclusions: Both FV and PV were fairly high in this self-selected cohort of volunteers compared with a large health system ( http://ow.ly/O8Dx30b9Wuc ) and a global registry ( http://ow.ly/Uofg30h6Qen ). Most did not receive an anti-VZV vaccine, but a few received a live vaccine. Anti-viral prophylaxis was common, but not universal. Anti-PJP and levofloxacin use were reported by a minority of participants. Pt reported interventions via an online portal can help investigators survey the pt community and result in hypothesis generating research questions including investigating vaccine: types, dosing, sequencing, and use of anti-infective interventions.
