The Reevaluation Of Systemic Early Neuromuscular Blockade (ROSE) study, conducted by the NHLBI PETAL Clinical Trials Network, is an ideal trial for which to perform a concurrent qualitative implementation study (NCT02509078). NMB has the potential to substantially reduce mortality in ARDS. Yet NMB remains incompletely adopted for reasons that are poorly understood but likely relate to clinical equipoise, historical concerns about safety, and the inherent difficulties in providing complex practices in the intensive care unit (ICU). A better understanding of provider views regarding NMB will provide essential data to aid interpretation of study results and design an implementation study should ROSE demonstrate a survival benefit with NMB.
