Background: Critical care nurses who care for postoperative cardiac surgery patients need such specialty knowledge as atrial electrograms (AEGs). An inadequate audit trail exists for psychometric performance of instruments to measure knowledge of AEGs.Objectives: The aim of this study was to revise a previously tested instrument and assess evidence for content validity (content validity index), internal consistency (Cronbach α), and stability (correlation coefficient, r) reliability against the a priori criterion of 0.80. Methods: The multiple-choice response, self-administered, paper-and-pencil instrument was revised to 20 items and named the Drake Atrial Electrogram Assessment Survey (DAEGAS). A panel of 6 AEG experts reviewed the DAEGAS for content validity evidence. The instrument was further revised to 19 items (13 knowledge and 6 AEG interpretation) and tested with 76 critical care nurses from the greater Houston metropolitan area.Results: The content validity index was 0.93. Cronbach α was .51, and test-retest r was 0.74. Cronbach α increased to .60 and r was 0.73 with removal of 3 items: 2 items with a negative item-total correlation and 1 item that was transitioned to a sample question.Discussion: Content validity evidence exceeded the a priori criterion. Internal consistency and stability reliability estimates did not meet the criterion, albeit the latter met the criterion recommended by psychometricians for a new instrument. Recommendations include further development of the DAEGAS to improve internal consistency estimates and testing for evidence of other forms of validity.Reliable and valid assessment of critical care nurse knowledge of AEGs will require improved psychometric performance of the DAEGAS.

Background Critical care nurses working in urban settings have reported obstacles in caring for dying patients. However, the perceptions of such obstacles by nurses working in critical access hospitals (CAHs), which are located in rural areas, are unknown. Objective To study stories and experiences related to obstacles in providing end-of-life care reported by CAH nurses. Methods This exploratory, cross-sectional study presents the qualitative stories and experiences of nurses working in CAHs as reported on a questionnaire. Quantitative data have been previously reported. Results Sixty-four CAH nurses provided 95 categorizable responses. Two major categories emerged: (1) family, physician, and ancillary staff issues and (2) nursing, environment, protocol, and miscellaneous issues. Issues with family behaviors were families’ insistence on futile care, intrafamily disagreement about do-not-resuscitate and do-not-intubate orders, issues with out-of-town family members, and family members’ desire to hasten the patient’s death. Issues with physician behaviors were providing false hope, dishonest communication, continuation of futile treatments, and not ordering pain medications. Nursing-related issues were not having enough time to provide end-of-life care, already knowing the patient or family, and compassion for the dying patient and the family. Conclusion Family issues and physician behaviors are common obstacles in rural nurses’ provision of end-of-life care. Education of family members on end-of-life care is challenging because it is most families’ first experience with intensive care unit terminology and technology. Further research on end-of-life care in CAHs is needed.
