Impact of Mindfulness Training on Nursing Burnout and Care Quality in ICUs

Thesis Abstract

The escalating prevalence of burnout among critical care nurses and its detrimental impact on patient care outcomes necessitate evidence-based interventions within intensive care units (ICUs). This study investigates the impact of a structured mindfulness training program on nursing burnout and perceived care quality in ICUs, addressing the gap where mindfulness is variably adopted and its effects on both staff well-being and patient-centered outcomes remain inconclusive. The aim is to evaluate whether an eight-week mindfulness-based intervention reduces burnout levels and enhances perceived care quality among ICU nurses. Specific objectives include (1) assessing baseline levels of burnout, job satisfaction, and perceived care quality; (2) implementing a standardized mindfulness training module tailored for high-acuity environments; (3) examining post-intervention changes in burnout dimensions (emotional exhaustion, depersonalization, personal accomplishment) using validated instruments; (4) evaluating shifts in perceived care quality and safety climate; and (5) identifying moderating factors such as years of ICU experience and shift pattern. Theoretical underpinning integrates the Job Demands-Resources (JD-R) model to frame burnout processes and the Mindfulness-to-Meaning theory to explain adaptive outcomes of mindfulness practice on clinical performance. A quasi-experimental, non-equivalent control group design will be employed across four tertiary hospital ICUs. The population comprises registered ICU nurses with at least six months of continuous ICU experience. A total sample of 200 participants will be recruited, with 100 assigned to the intervention group and 100 to a wait-list control group, matched on unit, shift, and tenure. Data will be collected at three time points baseline (T0), immediately post-intervention (T1, eight weeks), and three-month follow-up (T2). Instruments include the Maslach Burnout Inventory–Human Services Survey (MBI-HSS) to assess emotional exhaustion, depersonalization, and personal accomplishment; the Nursing Practice Quality Scale (NPQS) to gauge perceived care quality and patient safety climate; the Five Facet Mindfulness Questionnaire (FFMQ) to measure mindfulness trait changes; and a demographic questionnaire. Intervention fidelity will be ensured through standardized delivery by trained facilitators, weekly practice logs, and session checklists. Data analyses will involve mixed-methods approaches quantitative analyses will utilize repeated-measures ANOVA and hierarchical multiple regression to detect intervention effects and potential moderators, with intention-to-treat handling and multiple imputation for missing data. Effect sizes will be reported (Cohen’s d, partial eta-squared). The qualitative component will comprise semi-structured interviews with a purposive subsample of 20 participants from the intervention group at T2 to explore perceived mechanisms and contextual factors, analyzed via thematic analysis adhering to Lincoln and Guba’s trustworthiness criteria. Anticipated findings include significant reductions in emotional exhaustion and depersonalization, with improvements in personal accomplishment and perceived care quality in the mindfulness group relative to controls, maintained at three-month follow-up. The study expects that higher baseline stress and longer ICU tenure may moderate effects, with novice nurses showing greater relative gains. The contribution to knowledge lies in providing robust, empirically grounded evidence on the feasibility, effectiveness, and mechanisms of mindfulness interventions in acute care settings, integrating JD-R theory with mindfulness processes to elucidate pathways from staff well-being to patient care outcomes. Practical implications include informing organizational strategies for workforce resilience, integration of mindfulness programs into continuing professional development, and policy recommendations for staffing and support in ICUs. The study concludes that structured mindfulness training can be a scalable, evidence-based approach to mitigating burnout and enhancing care quality in high-stress critical care environments, with sustained benefits corroborated by follow-up data and qualitative insights. Recommendations include broader implementation with unit-level management support, ongoing practice reinforcement, consideration of differential effects across roles and shifts, and future research to examine long-term patient outcomes and cost-effectiveness analyses.
