BACKGROUND:This cross-sectional survey aimed to establish the prevalence of infectious diseases and vaccination uptake in long-term allogeneic hematopoietic stem cell transplants (HSCT) survivors in New South Wales, in order to reduce long-term post-HSCT morbidity and mortality and enhance long-term care. PATIENTS AND METHODS:Hematopoietic stem cell transplants survivors aged over 18 years and transplanted between 2000-2012 in New South Wales (NSW) were eligible to participate. Survivors self-completed the Sydney Post BMT Study survey, FACT-BMT (V4), Chronic Graft versus Host Disease (cGVHD) Activity Assessment Self Report, Lee Chronic GvHD Symptom Scale, DASS21, Post Traumatic Growth Inventory, and the Fear of Recurrence Scale. RESULTS:Of the 583 HSCT survivors contacted, 441 (78%) completed the survey. Respondents included 250 (57%) males and median age was 54 years (range 19-79 years). The median age at the time of transplant was 49 years (Range: 17-71), the median time since HSCT was 5 years (Range: 1-14) and 69% had cGVHD. Collectively, 41.7% of survivors reported a vaccine preventable disease (VPD) with the most common being influenza-like-illness (38.4%), varicella zoster/shingles (27.9%), pap smear abnormalities (9.8%), pneumococcal disease (5.1%), and varicella zoster (chicken pox) (4.6%). Only 31.8% had received the full post-HSCT vaccination schedule, and the majority (69.8%) of these had received the vaccines via their General Practitioner. cGVHD was not found to be a significant factor on multivariate analysis for those who were vaccinated. There was a trend toward lower vaccination rates in patients in a lower income strata. CONCLUSIONS:Vaccinating post-HSCT survivors to prevent infections and their consequences have an established role in post-HSCT care. Improving rates of post-HSCT vaccination should be a major priority for BMT units.
