Background and purpose Little data is available on the effect of mindfulness amongst pediatric hematology-oncology professionals. The purpose was to further document change in biological and psychological stress following a mindfulness-based stress reduction (MBSR) program. Materials and methods We led two pre-post interventional studies (n = 12 and n = 25) and measured changes on hair cortisol concentrations, perceived stress, psychological distress and burnout. Results Professionals did not change on biological stress (d = 0.04), but improved on self-reported measures (median d = 0.58). Effects were maintained over 3 months for psychological distress, anxiety, depression, and burnout (median d = 0.66). Effects were larger if trainees participated to the retreat and if they reported higher baseline perceived stress. Conclusion In pediatric hematology-oncology professionals, an MBSR program was related with improvements in self-reported stress over 3 months. Components of the program and characteristics of trainees may influence the impact of MBSR.
