Summary

Organizational changes in a pediatric intensive care unit reduced salivary cortisol levels in one nursing team. Staff disruption in another team negated these stress-reducing effects, highlighting the importance of team cohesion.

Area of Science:

  • Occupational Health
  • Endocrinology
  • Nursing Research

Background:

  • Psychomental stress significantly impacts healthcare worker well-being and productivity.
  • Physiological stress markers, such as salivary cortisol, are underutilized in assessing workplace stress.
  • Pediatric critical care units present a highly stressful environment for nursing staff.

Purpose of the Study:

  • To identify organizational changes to mitigate stress in a pediatric intensive care unit.
  • To implement targeted interventions aimed at reducing workplace stressors.
  • To evaluate the impact of these organizational changes on nurses' physiological stress levels, measured by salivary cortisol.

Main Methods:

  • A repeated measurements observational cohort study design was employed.

Related Experiment Videos

  • 84 nurses from two independent teams (A and B) in a pediatric intensive care unit participated.
  • Salivary cortisol was measured every 2 hours and after stressful events, before and after intervention implementation.

    • Main Results:

    • Team B, which experienced stable staffing, showed a significant decrease in salivary cortisol levels at the start of the late shift post-intervention (p = 0.0009).
    • Team A, which underwent significant staff changes, did not exhibit a significant reduction in cortisol levels (p = 0.464).
    • A control group (early shift) demonstrated no significant changes in cortisol levels between study periods.

    Conclusions:

    • Organizational changes can effectively reduce physiological stress markers like cortisol in healthcare settings.
    • Disruption of social coherence due to high staff turnover can override the benefits of organizational interventions.
    • Maintaining team stability is crucial for maximizing the positive impact of workplace improvements on staff well-being.
