Improving care for patients dying in the intensive care unit

Moral distress and its influencing factors: A cross-sectional study in China

Objective:

The purpose of this study was to describe the current situation of moral distress and to explore its influencing factors among Chinese nurses.

Methods:

This is an exploratory, descriptive design study. A total of 465 clinical nurses from different departments in three Grade-III, Level-A hospitals in Jinan, Shandong Province, completed the questionnaires, including demographics questionnaire, Chinese version of Moral Distress Scale–Revised, and Job Diagnostic Survey.

Ethical considerations:

The study was approved by the university ethics board and the local health service director.

Results:

The total score of Moral Distress Scale–Revised was 36.01 ± 24.02 points. The mean frequency and intensity scores of moral distress were 1.13 ± 0.49 and 1.09 ± 0.58, respectively. The level of moral distress among Chinese clinical nurses was low, and the frequency and intensity of moral distress were on low to moderate level. The level of moral distress experienced by clinical nurses is associated with demographics features and job characteristics, including age, education degree, department, task significance, autonomy, and dealing with others.

Conclusion:

Our conclusion suggests that hospital and organizational administrations should attach much importance to the moral distress experienced by clinical nurses in China. Further studies should focus on interventions about how to reduce the levels of the frequency and intensity of moral distress among clinical nurses.

Comparison of APACHE III, APACHE IV, SAPS 3, and MPM0III and influence of resuscitation status on model performance

BACKGROUND

There are few comparisons among the most recent versions of the major adult ICU prognostic systems (APACHE [Acute Physiology and Chronic Health Evaluation] IV, Simplified Acute Physiology Score [SAPS] 3, Mortality Probability Model [MPM]0III). Only MPM0III includes resuscitation status as a predictor.

METHODS

We assessed the discrimination, calibration, and overall performance of the models in 2,596 patients in three ICUs at our tertiary referral center in 2006. For APACHE and SAPS, the analyses were repeated with and without inclusion of resuscitation status as a predictor variable.

RESULTS

Of the 2,596 patients studied, 283 (10.9%) died before hospital discharge. The areas under the curve (95% CI) of the models for prediction of hospital mortality were 0.868 (0.854-0.880), 0.861 (0.847-0.874), 0.801 (0.785-0.816), and 0.721 (0.704-0.738) for APACHE III, APACHE IV, SAPS 3, and MPM0III, respectively. The Hosmer-Lemeshow statistics for the models were 33.7, 31.0, 36.6, and 21.8 for APACHE III, APACHE IV, SAPS 3, and MPM0III, respectively. Each of the Hosmer-Lemeshow statistics generated P values < .05, indicating poor calibration. Brier scores for the models were 0.0771, 0.0749, 0.0890, and 0.0932, respectively. There were no significant differences between the discriminative ability or the calibration of APACHE or SAPS with and without “do not resuscitate” status.

CONCLUSIONS

APACHE III and IV had similar discriminatory capability and both were better than SAPS 3, which was better than MPM0III. The calibrations of the models studied were poor. Overall, models with more predictor variables performed better than those with fewer. The addition of resuscitation status did not improve APACHE III or IV or SAPS 3 prediction.

Nurse-physician perspectives on the care of dying patients in intensive care units: collaboration, moral distress, and ethical climate

OBJECTIVE

To explore registered nurses' and attending physicians' perspectives on caring for dying patients in intensive care units (ICUs), with particular attention to the relationships among moral distress, ethical climate, physician/nurse collaboration, and satisfaction with quality of care.

DESIGN

Descriptive pilot study using a survey design.

SETTING

Fourteen ICUs in two institutions in different regions of Virginia.

SUBJECTS

Twenty-nine attending physicians who admitted patients to the ICUs and 196 registered nurses engaged in direct patient care.

INTERVENTIONS

Survey questionnaire.

MEASUREMENTS AND MAIN RESULTS

At the first site, registered nurses reported lower collaboration (p<.001), higher moral distress (p<.001), a more negative ethical environment (p<.001), and less satisfaction with quality of care (p=.005) than did attending physicians. The highest moral distress situations for both registered nurses and physicians involved those situations in which caregivers felt pressured to continue unwarranted aggressive treatment. Nurses perceived distressing situations occurring more frequently than did physicians. At the second site, 45% of the registered nurses surveyed reported having left or considered leaving a position because of moral distress. For physicians, collaboration related to satisfaction with quality of care (p<.001) and ethical environment (p=.004); for nurses, collaboration was related to satisfaction (p<.001) and ethical climate (p<.001) at both sites and negatively related to moral distress at site 2 (p=.05). Overall, registered nurses with higher moral distress scores had lower satisfaction with quality of care (p<.001), lower perception of ethical environment (p<.001), and lower perception of collaboration (p<.001).

CONCLUSIONS

Registered nurses experienced more moral distress and lower collaboration than physicians, they perceived their ethical environment as more negative, and they were less satisfied with the quality of care provided on their units than were physicians. Provider assessments of quality of care were strongly related to perception of collaboration. Improving the ethical climate in ICUs through explicit discussions of moral distress, recognition of differences in nurse/physician values, and improving collaboration may mitigate frustration arising from differences in perspective.
