Project Summary/Abstract: Healthcare provider burnout is pervasive in oncology, and it imparts harm to providers and patients, increases healthcare and workforce disparities, and exacerbates projected physician and nursing shortages. Although burnout is primarily caused by organizational stressors, supportive and cooperative interdisciplinary teams foster psychological safety and are protective against burnout. For this reason, interventions to improve burnout require organization-directed approaches that address team dynamics and working environment (as opposed to only focusing on individual resilience). Although there has been a multitude of small studies investigating several interventions to prevent burnout, the evidence base remains extremely low due to the poor quality of data and measurement approaches. As a first step to address the critical and unmet need for evidence-based, acceptable, and scalable team-based interventions to improve burnout, we developed Compassion Centered Spiritual Health Team Intervention (CCSH-TI), which includes mindfulness and compassion-based approaches to bolster compassion for self and others and to improve psychological safety and team civility. CCSH-TI is delivered by hospital chaplains who comprise a well-established and highly acceptable non-sectarian clinical service present in nearly two-thirds of all US hospitals and trained to provide emotional, psychosocial, and spiritual care to a broad range of patients and staff. The current proposal will use a phase 1 clustered randomized, wait-list controlled, and mixed-method study to (1) examine the feasibility and acceptability of CCSH-TI and (2) develop and validate a novel, low-burden ambulatory assessment “toolkit” to improve the measurement of psychological safety and burnout. Employees (n = 80; nurses, advanced practice providers (APPs), physicians, staff) working at an NCI-designated Comprehensive Cancer Center will be randomized by team to CCSH-TI or wait-list. We will evaluate CCSH-TI feasibility (accrual, retention, CCSH-TI attendance) and acceptability (satisfaction, credibility, perceived benefit). Focus groups will identify contextual determinants of feasibility, acceptability, and implementation success. At pre/post-intervention and 12-week follow-up, we will conduct 3-day ambulatory assessments: (1) Ecological Momentary Assessments (EMA) of social connection, incivility, and burnout; and (2) Electronically Activated Recorder (EAR), a method of periodically and unobtrusively sampling acoustic observations that has been validated and established outside the healthcare environment. We will develop and validate EAR behavioral codebooks tailored to the healthcare environment to quantify behavioral indices of psychological safety, incivility, and interprofessional teamwork. This proposal is an innovative and ‘real world’ approach to increase access, equity, and inclusion of burnout prevention and mitigation among all healthcare providers and that impro...
