Clinical Predictive Models of Sudden Cardiac Arrest: A Survey of the Current Science and Analysis of Model Performances

Background

More than 500 000 sudden cardiac arrests (SCAs) occur annually in the United States. Clinical predictive models (CPMs) may be helpful tools to differentiate between patients who are likely to survive or have good neurologic recovery and those who are not. However, which CPMs are most reliable for discriminating between outcomes in SCA is not known.

Methods and Results

We performed a systematic review of the literature using the Tufts PACE (Predictive Analytics and Comparative Effectiveness) CPM Registry through February 1, 2020, and identified 81 unique CPMs of SCA and 62 subsequent external validation studies. Initial cardiac rhythm, age, and duration of cardiopulmonary resuscitation were the 3 most commonly used predictive variables. Only 33 of the 81 novel SCA CPMs (41%) were validated at least once. Of 81 novel SCA CPMs, 56 (69%) and 61 of 62 validation studies (98%) reported discrimination, with median c‐statistics of 0.84 and 0.81, respectively. Calibration was reported in only 29 of 62 validation studies (41.9%). For those novel models that both reported discrimination and were validated (26 models), the median percentage change in discrimination was −1.6%. We identified 3 CPMs that had undergone at least 3 external validation studies: the out‐of‐hospital cardiac arrest score (9 validations; median c‐statistic, 0.79), the cardiac arrest hospital prognosis score (6 validations; median c‐statistic, 0.83), and the good outcome following attempted resuscitation score (6 validations; median c‐statistic, 0.76).

Conclusions

Although only a small number of SCA CPMs have been rigorously validated, the ones that have been demonstrate good discrimination.

Critical Care Nurses’ Perceptions of Futile Care and Its Effect on Burnout

• Background Nurses’ perceptions of futile care may lead to emotional exhaustion.

• Objectives To determine the relationship between critical care nurses’ perceptions of futile care and its effect on burnout.

• Methods A descriptive survey design was used with 60 critical care nurses who worked full-time and had a minimum of 1 year of critical care experience at the 2 participating hospitals (350–470 beds). Subjects completed a survey on demographics, the Moral Distress Scale, and the Maslach Burnout Inventory. Six research questions were tested. The results of the following question are presented: Is there a relationship between frequency of moral distress situations involving futile care and emotional exhaustion?

• Results A Pearson product moment correlational analysis indicated a significant positive correlation between the score on the emotional exhaustion subscale of the Maslach Burnout Inventory and the score on the frequency subscale of the Moral Distress Scale. Moral distress accounted for 10% of the variance in emotional exhaustion. Demographic variables of age, education, religion, and rotation between the critical care units were significantly related to the major variables.

• Conclusions In critical care nurses, the frequency of moral distress situations that are perceived as futile or nonbeneficial to their patients has a significant relationship to the experience of emotional exhaustion, a main component of burnout.

Intensive care nurses' and physicians' experiences with demands for treatment: some implications for clinical practice

OBJECTIVE

This study was conducted to develop an empiric description of intensive care unit (ICU) physicians' and nurses' (participants) experiences providing life-sustaining treatments at the insistence of family members, treatments that they believed should have been withheld or withdrawn. From this description, steps to minimize or prevent their sources of distress in such situations are suggested.

DESIGN

Semistructured, open-ended interviews. Participants were asked to describe cases in which treatment had been provided primarily in response to demands from family members.

PARTICIPANTS

Six physicians and 6 nurses from 6 university-affiliated ICUs in Canada. All were members of a task force developing a multicenter policy to address demands for treatment, and physician members were heads of their ICUs.

OUTCOME MEASURES

Systematic analysis of interview transcripts and synthesis of findings.

RESULTS

Participants recalled 28 cases in which treatment had been provided at the insistence of family members. Many cases described were very distressing for both medical staff and family members. Consistently problematic areas included: (1) suffering of dying patients, (2) the marked distress of family members, and (3) a breakdown in the relationship between care providers and families.

CONCLUSIONS

Conflict with family members about decisions to limit life-sustaining treatment can be very stressful for health care providers. Three important areas that give rise to distress were identified in this study. These key sources of distress should be looked for. They could be addressed by: (1) identifying to family members the importance of minimizing suffering and ongoing bodily injury of patients at risk for dying, (2) by doing so addressing directly the distress of family members by the provision of emotional support, and when appropriate directed toward helping them accept that the patient is dying, and (3) pursuing efforts to maintain or create a good relationship with family members despite disagreement about the appropriateness of continuing life-sustaining treatment.

Hospice quality improvement programs: an initial examination

Recognizing that little is known about use of quality improvement (QI) processes to enhance care of the dying, 11 large hospices exchanged information about their QI programs. These hospices reported monitoring from 3 to 50 outcomes measured by various indicators and methods. Agencies that related QI to their organization's mission, goals, and strategic plan were more likely to have dedicated QI staff; a more intense, comprehensive, and participatory QI program; and more QI projects resulting in performance enhancement. Both accomplishments and difficulties were identified in several areas, including establishing benchmarks, involving staff, and using computer technology to manage and analyze QI data.

Ethical decisions in perioperative elder care

Settings involving the extremes of age and illness are the most complex in ethical deliberation and require sound principles that can be clearly applied to individual situations. This article discusses how one's view of the aging process effects clinical decision making. The basic principles of medical ethics (autonomy, beneficence, nonmaleficence, and justice) are discussed along with alternative ethical paradigms that may be more appropriate to the elderly population. Issues such as informed consent, do not resuscitate orders in the operating room, and controversies in end-of-life palliative care specifically impact the role of the anesthesiologist. Anesthesiologists, as medical professionals in a health care team, have a great stake in ethical decision making and the ethics of health care policy.

Futile care: confronting the high costs of dying

The costs of futile care for the dying are great. Futility can present challenges because of the monetary costs of such care, its negative effects on staff members, and the burden it creates in allocating limited resources. Administrators can work to recognize and form a better understanding of futility and thus develop strategies for decreasing non-beneficial care. The author discusses issues surrounding futile care and offers suggestions for administrators to decrease spending related to the administration of futile care for the dying.
