Abstract
BACKGROUND: Biobehavioral interventions including relaxation, distraction, and mindfulness meditation exercises have been shown to decrease perioperative stress, anxiety, and pain. Our aims were to 1) quantify pediatric surgical patient-reported pre-operative exposure to and post-operative use of biobehavioral interventions; 2) understand barriers and facilitators to incorporation of biobehavioral interventions into clinical practice; and 3) evaluate associated patient-reported outcomes. METHODS: We conducted an embedded mixed-methods study with a quantitative focus. Data were collected as part of the 18-hospital ENhanced Recovery In CHildren Undergoing Surgery (ENRICH-US) clinical trial for children, ages 10-18 years, undergoing elective gastrointestinal surgery. Patients/caregivers were surveyed about preoperative exposure to and postoperative use of biobehavioral interventions. Four semi-structured group interviews with 20 pediatric surgery providers were conducted. Outcomes included pain-related functional disability, health-related quality of life (HRQoL), and perioperative nervousness. RESULTS: 41 % (n = 67) of 164 enrolled patients/caregivers reported preoperative exposure to and 71 % (n = 117) reported postoperative use of a biobehavioral intervention(s). Barriers to incorporation of biobehavioral interventions included lack of standardized workflows, clinician knowledge, and resources. Potential facilitators included media and peer-counseling. After adjusting for individual and hospital characteristics, those who reported using a biobehavioral intervention(s) were 70 % less likely to report worsened postoperative nervousness (95 % CI 0.10-0.91; p = 0.03). Reported use of a biobehavioral intervention(s) was not found to be associated with pain-related functional disability or HRQoL. CONCLUSIONS: Use of a biobehavioral intervention(s) may stabilize postoperative nervousness of children undergoing surgery. There is a need for redesign of clinical workflows and clinician training to facilitate integration of biobehavioral interventions.
