Ethical issues in the critically ill patient

A Qualitative Analysis of Ethical Problems Experienced by Physicians and Nurses in Intensive Care Units in Turkey

In this qualitative study, we aimed to identify and compare the ethical problems perceived by physicians and nurses in intensive care units at Baskent University hospitals in Turkey. A total of 21 physicians and 22 nurses were asked to describe ethical problems that they frequently encounter in their practice. The data were analyzed using an interactive model. The core problem for both physicians and nurses was end-of-life decisions (first level). In this category, physicians were most frequently concerned with euthanasia while nurses were more concerned with do-not-resuscitate orders (second level). At the third level, we saw that almost all of the participants’ responses related to negative perceptions about euthanasia. Communication and hierarchical problems were the second most reported main category. Nurses were more likely to cite problems with hierarchy than physicians. At the third level, a large percentage of nurses described communication problems with authority and hierarchical problems with physicians. In the same category, physicians were most often concerned with communication problems with patients’ relatives. The ethical problems were reported at different frequencies by physicians and nurses. We asked the participants about ethical decision-making styles. The results show that nurses and physicians do not follow a systematic pattern of ethical decision making.

Ethical decision making in intensive care units: a burnout risk factor? Results from a multicentre study conducted with physicians and nurses

BACKGROUND

Ethical decision making in intensive care is a demanding task. The need to proceed to ethical decision is considered to be a stress factor that may lead to burnout. The aim of this study is to explore the ethical problems that may increase burnout levels among physicians and nurses working in Portuguese intensive care units (ICUs). A quantitative, multicentre, correlational study was conducted among 300 professionals.

RESULTS

The most crucial ethical decisions made by professionals working in ICU were related to communication, withholding or withdrawing treatments and terminal sedation. A positive relation was found between ethical decision making and burnout in nurses, namely, between burnout and the need to withdraw treatments (p=0.032), to withhold treatments (p=0.002) and to proceed to terminal sedation (p=0.005). This did not apply to physicians. Emotional exhaustion was the burnout subdimension most affected by the ethical decision. The nurses' lack of involvement in ethical decision making was identified as a risk factor. Nevertheless, in comparison with nurses (6%), it was the physicians (34%) who more keenly felt the need to proceed to ethical decisions in ICU.

CONCLUSIONS

Ethical problems were reported at different levels by physicians and nurses. The type of ethical decisions made by nurses working in Portuguese ICUs had an impact on burnout levels. This did not apply to physicians. This study highlights the need for education in the field of ethics in ICUs and the need to foster inter-disciplinary discussion so as to encourage ethical team deliberation in order to prevent burnout.

Review article: scoring systems for assessing prognosis in critically ill adult cirrhotics

BACKGROUND

Cirrhotic patients admitted to intensive care units (ICU) still have poor outcomes. Some current ICU prognostic models [Acute Physiology and Chronic Health Evaluation (APACHE), Organ System Failure (OSF) and Sequential Organ Failure Assessment (SOFA)] were used to stratify cirrhotics into risk categories, but few cirrhotics were included in the original model development. Liver-specific scores [Child-Turcotte-Pugh (CTP) and model for end-stage liver disease (MELD)] could be useful in this setting.

AIM

To evaluate whether ICU prognostic models perform better compared with liver-disease specific ones in cirrhotics admitted to ICU.

METHODS

We performed a structured literature review identifying clinical studies focusing on prognosis and risk factors for mortality in adult cirrhotics admitted to ICU.

RESULTS

We found 21 studies (five solely dealing with gastrointestinal bleeding) published during the last 20 years (54-420 patients in each). APACHE II and III, SOFA and OSF had better discrimination for correctly predicting death compared with the CTP score. The MELD score was evaluated only in one study and had good predictive accuracy [receiver operator characteristic (ROC) curve: 0.81). Organ dysfunction models (OSF, SOFA) were superior compared with APACHE II and III (ROC curve: range 0.83-0.94 vs. 0.66-0.88 respectively). Cardiovascular, liver and renal system dysfunction were more frequently independently associated with mortality.

CONCLUSIONS

General-ICU models had better performance in cirrhotic populations compared with CTP score; OSF and SOFA had the best predictive ability. Further prospective and validation studies are needed.

A concept analysis of palliative care in the United States

PURPOSE

The purpose of this analysis is to trace the evolution of the concept of palliative in the United States, explicate its meanings, and draw comparisons with other related concepts such as hospice care and terminal care.

METHODS

Rodgers' evolutionary method was used as an organizing framework for the concept analysis. Data were collected from a review of CINAHL, MEDLINE, CANCERLIT, PsycINFO and Sociological Abstracts databases using 'palliative care' and 'United States' as keywords. Articles written in the English language, with an abstract, published between 1965 and 2003 were considered. Data were synthesized to identify attributes, antecedents and consequences of palliative care.

FINDINGS

There has been a significant evolution in understanding of the palliative care concept in the United States over the last few decades, which has resulted in the emergence of new models of palliative care. Four attributes of the current palliative care concept were identified: (1) total, active and individualized patient care, (2) support for the family, (3) interdisciplinary teamwork and (4) effective communication. Results reinforce that cure and palliation are not mutually exclusive categories.

CONCLUSIONS

The scope of palliative care has evolved to include a wide range of patient populations who may not be appropriately termed 'dying' but for whom alleviation of suffering and improvement of quality of life may be very relevant goals. The ultimate success of the new models of palliative care will eventually rest upon the commitment of health professionals to recognize and integrate the changing concept of palliative care into everyday practice.
