BACKGROUND

We examined the impact of vancomycin-resistant Enterococcus (VRE) bloodstream infection (BSI) on outcomes of allogeneic hematopoietic cell transplantation (HCT) utilizing the Center for International Blood and Marrow Transplant Research database.

METHODS

Adult and pediatric patients (N = 7128) who underwent first HCT for acute leukemia or myelodysplastic syndrome from 2008 through 2012 were analyzed as 3 groups-VRE BSI, non-VRE BSI, without BSI-according to BSI status at 100 days (D100) after allogeneic HCT. Multivariable models examined the effect of VRE BSI for overall survival (OS) and nonrelapse mortality (NRM) at 1 year.

RESULTS

Of 7128 patients, 258 (3.2%) had VRE BSI, 2398 (33.6%) had non-VRE BSI, and 4472 (63%) had no BSI. The median time to VRE BSI and non-VRE BSI were D11 and D15, respectively. Compared with non-VRE BSI patients, VRE BSI patients were older, had advanced-stage acute leukemia, and received umbilical cord blood (UCB) allografts. In multivariable models, VRE BSI was associated with lower OS (relative risk [RR], 2.9;(99% confidence interval [CI], 2.2-3.7) and increased NRM (RR, 4.7; 99% CI, 3.6-6.2) (P < .0001) for both. Other predictors for worse OS and increased NRM were non-VRE BSI, older age, advanced disease stage, UCB allograft, - mismatch, comorbidity index ≥3, and cytomegalovirus seropositivity (P < .001 for all variables).

CONCLUSIONS

VRE BSI is associated with lowest OS and highest NRM compared with patients without BSI or non-VRE BSI. Novel interventions that address the pathophysiology of VRE BSI have the potential of improving survival after HCT.

Institutions have developed professionalism policies to help guide physician social media behavior in light of professionalism lapses that have resulted in serious consequences. Prior research has gathered perspectives on online professionalism; however, the public's views remain poorly understood. Importantly, the impact of physician social media behavior on patient trust is unknown. To determine whether patients' trust might change based on their physicians' social media behavior, we conducted a cross-sectional survey across three U.S. cities ( = 491). The survey assessed patient trust using hypothetical scenarios. Most respondents reported they would have less trust if their physician posted racist comments online, wrote a disrespectful patient narrative, appeared intoxicated in a photograph, or wrote profanity. Respondent age and education impacted change in trust. We conclude that physicians' social media behavior may affect patient trust. Better understanding of how physicians' online presence impacts their relationships with patients can help guide policy and inform educational efforts.
