Stressors associated with coronary bypass surgery.

J A Carr, M J Powers

    Nursing Research

    Summary

    This study developed a stressor scale for coronary bypass surgery patients. Cardiothoracic nurses perceived significantly more patient stress than patients themselves reported.

    Area of Science:

    • Cardiovascular Surgery
    • Psychological Stress
    • Patient Experience

    Background:

    • Coronary bypass surgery (CBS) is a significant medical procedure associated with patient stress.
    • Understanding patient and healthcare provider perceptions of stressors is crucial for improving care.
    • Existing instruments may not fully capture the nuances of CBS-related stressors.

    Purpose of the Study:

    • To design and validate an instrument measuring the incidence and severity of stressors in coronary bypass surgery patients.
    • To assess the agreement between patient and nurse perceptions of these stressors.
    • To provide a reliable tool for evaluating patient psychological responses to CBS.

    Main Methods:

    • Development of a 30-item stressor scale, with items sourced from literature and expert input.
    • Pilot testing with seven patients for initial scale refinement.
    • Content validity established through diverse item sourcing and validation.
    • Reliability assessed using coefficient alphas.
    • Two-way analysis of variance used to compare patient and nurse stress ratings.

    Main Results:

    • The developed stressor scale demonstrated strong content validity and homogeneity reliability.
    • Patients (n=30) and nurses (n=18) rated the stressfulness of items on a 5-point scale.
    • Cardiothoracic nurses consistently rated items as significantly more stressful for patients compared to patients' self-ratings.
    • Discrepancies in stress perception between patients and nurses were observed.

    Conclusions:

    • The new instrument is a valid and reliable tool for assessing stressors in coronary bypass surgery patients.
    • A significant disparity exists between patient and nurse perceptions of surgical stress.
    • These findings highlight the need for tailored interventions addressing both patient-reported and nurse-perceived stressors.
