High-dose influenza vaccine use among patients receiving hemodialysis in the United States, 2010-2013.

ABSTRACT: BACKGROUND:Standard influenza vaccines may be of limited benefit to patients with end-stage renal disease (ESRD). These patients may benefit from high-dose influenza vaccine, currently indicated for patients aged ?65?years. Studies in other populations have demonstrated that high-dose vaccine elicits a stronger immunological response. We compared vaccine uptake in the United States and predictors of receipt for high-dose and standard influenza vaccines. METHODS:Using data from the United States Renal Data System (2010-2013), we conducted a cohort study of 421,482 adult patients on hemodialysis. We examined temporal trends in uptake of high-dose or standard trivalent influenza vaccine each influenza season, and used multivariate logistic regression to assess the association between individual-level variables (e.g., demographics, comorbidities) and facility-level variables (e.g., facility size and type) with vaccine receipt. RESULTS:The proportion of patients with ESRD who were vaccinated with any influenza vaccine increased from 68.3% in 2010 to 72.4% in 2013. High-dose vaccines were administered to 0.9% of patients during the study period, and 16.7% of high-dose vaccines were administered to patients <65?years of age. Among patients aged ?65?years, older patients (>79 vs. 65-69?years: OR, 1.29; 95% CI, 1.19-1.41) and patients at hospital-based versus free-standing dialysis facilities (OR, 2.31; 95% CI, 2.13-2.45) were more likely to receive high-dose vaccine, while blacks (vs. whites [OR, 0.66; 95% CI, 0.61-0.71]) and patients with longer duration of ESRD (>9 vs. 0?years: OR, 0.66; 95% CI, 0.55-0.78) were less likely to receive the high-dose vaccine. CONCLUSIONS:While the overall influenza vaccination rate has increased, use of high-dose vaccine among patients with ESRD was very low. Being an older patient, living in the Midwest, and receiving care at hospital-based facilities were the strongest predictors of receiving high-dose vaccine.

Project description:Rationale & objectiveStudies of patients on maintenance dialysis therapy suggest that standard-dose influenza vaccine (SDV) may not prevent influenza-related outcomes. Little is known about the comparative effectiveness of SDV versus high-dose influenza vaccine (HDV) in this population.Study designCohort study using data from the US Renal Data System.Setting & participants507,552 adults undergoing in-center maintenance hemodialysis between the 2010 to 2011 and 2014 to 2015 influenza seasons.ExposuresSDV and HDV.OutcomesAll-cause mortality, hospitalization due to influenza or pneumonia, and influenza-like illness during the influenza season.Analytic approachPatients were eligible for inclusion in multiple yearly cohorts; thus, our unit of analysis was the influenza patient-season. To examine the relationship between vaccine dose and effectiveness outcomes, we estimated risk differences and risk ratios using propensity score weighting of Kaplan-Meier functions, accounting for a wide range of patient- and facility-level characteristics. For nonmortality outcomes, we used competing-risk methods to account for the high mortality rate in the dialysis population.ResultsWithin 225,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. We observed similar risk estimates for HDV and SDV recipients for mortality (risk difference, -0.08%; 95% CI, -0.85% to 0.80%), hospitalization due to influenza or pneumonia (risk difference, 0.15%; 95% CI, -0.69% to 0.93%), and influenza-like illness (risk difference, 0.00%; 95% CI, -1.50% to 1.08%). Our findings were similar among adults younger than 65 years, as well as within other subgroups defined by influenza season, age group, dialysis vintage, month of influenza vaccination, and vaccine valence.LimitationsResidual confounding and outcome misclassification.ConclusionsThe HDV does not appear to provide additional protection beyond the SDV against all-cause mortality or influenza-related outcomes for adults undergoing hemodialysis. The additional cost and side effects associated with HDV should be considered when offering this vaccine. Future studies of HDV and other influenza vaccine strategies are warranted.

Project description:BackgroundLive attenuated influenza vaccine (LAIV) is safe in healthy children ⩾2years. The original clinical trials excluded individuals with underlying conditions; however, post-marketing data suggest LAIV may be safe for these populations.MethodsWe analyzed MarketScan Commercial Claims Databases from 2010 to 2012 to describe hospitalizations within 14days of vaccination among LAIV recipients. We evaluated LAIV recipients aged 2-18years and defined underlying conditions by presence of inpatient or outpatient ICD-9 code during the previous calendar year. We excluded asthma and immunocompromising conditions. We defined risk windows as 1-7days and 8-14days after vaccination; the control period was 12-4days prior to and 15-23days after vaccination. We conducted a self-controlled case series analysis using a conditional Poisson regression model to estimate incidence-rate ratios (IRR).Results1,216,123 children aged 2-18years received LAIV from 2010 to 2012. 634 children met our inclusion criteria and were hospitalized during the observation period (12days prior to vaccination to 23days after vaccination). Of those hospitalized, 72 (11.4%) had non-asthma, non-immunocompromising underlying conditions. Children with non-asthma, non-immunocompromising underlying conditions had an all-cause hospitalization IRR of 1.1 (95% CI 0.6-2.0, p=0.83) in the 1-7day risk period and 0.9 (95% CI 0.4-1.7, p=0.67) in the 8-14day risk period. Children with no underlying conditions had an all-cause hospitalization IRR of 0.9 (0.8-1.2, p=0.60) in the 1-7day risk period and 1.1 (95% CI 0.9-1.3, p=0.53) in the 8-14day risk period. There were no differences in all-cause hospitalization risk in individuals with non-asthma, non-immunocompromising underlying conditions compared to those without underlying conditions in the 1-7day (p=0.88) or 8-14day (p=0.24) risk period.ConclusionsWe found no evidence of differences in post-LAIV hospitalization risk among children with non-asthma, non-immunocompromising underlying conditions compared to healthy children.
