RESUMO
Advance directives entail a refusal expressed by a still-healthy patient. Three consequences stem from that fact: (a) advance refusal is unspecific, since it is impossible to predict what the patient's conditions and the risk-benefit ratio may be in the foreseeable future; (b) those decisions cannot be as well informed as those formulated while the disease is in progress; (c) while both current consent and refusal can be revoked as the disease unfolds, until the treatment starts out, advance directives become effective when the patient becomes incapable or unconscious; such decisions can therefore not be revoked at any stage of the disease. Therefore, advance directives are binding for doctors only at the stage of advance treatment planning, i.e., only if they refer to an illness already in progress.

'Do not resuscitate' (DNR) imprints on the human body have recently appeared in medical practice. These non-standard DNR orders (e.g., tattoos, stamps, patches) convey the patient's refusal of resuscitation efforts should he be incapable of doing so. The article focuses on such innovative tools to express one's end-of-life wishes. Switzerland provides a unique example, as 'No Cardio-Pulmonary Resuscitation' stamps and patches have been commercialised. The article discusses the challenging legal questions as to the validity of non-standard DNR orders imprinted on the human body. It analyses the obligation of healthcare providers to honour such orders, either as an advance directive or an expression of an individual's presumed wishes, and withhold treatment. Finally, the article addresses the balancing of interests between the presumed wishes of an unconscious patient and his best interests of being resuscitated and potentially staying alive, a dilemma facing healthcare providers in a medical emergency.

This paper takes a novel approach to the active bioethical debate over whether advance medical directives have moral authority in dementia cases. Many have assumed that advance directives would lack moral authority if dementia truly produced a complete discontinuity in personal identity, such that the predementia individual is a separate individual from the postdementia individual. I argue that even if dementia were to undermine personal identity, the continuity of the body and the predementia individual's rights over that body can support the moral authority of advance directives. I propose that the predementia individual retains posthumous rights over her body that she acquired through historical embodiment in that body, and further argue that claims grounded in historical embodiment can sometimes override or exclude moral claims grounded in current embodiment. I close by considering how advance directives grounded in historical embodiment might be employed in practice and what they would and would not justify.

BACKGROUND: Routine mammography improves survival. To achieve health benefits, women must attend breast screening regularly at recommended time intervals. Maltese women are routinely invited to undergo mammography at three-year intervals at an organized breast screening programme (MBSP) or can opt to attend a private clinic. Previous research shows that health beliefs, particularly perceived barriers, were the most significant predictors of uptake to the first MBSP invitation. Whether these beliefs and other factors are predictive of adherence with recommended time intervals for mammography at organized or private screening in Malta is unknown. For the first time, this paper explores the predictors for Maltese women screened within or exceeding the recommended three-year frequency in organized or private screening in Malta. METHODS: Information was obtained from a cross-sectional survey of 404 women, aged 50 to 60 years at the time of their first MBSP invitation, where women's characteristics, knowledge, health beliefs and illness perceptions were compared. The main variable of interest was women's mammography attendance within a three-year interval (ADHERENT) or exceeding three years (NON-ADHERENT). Data were analysed using descriptive statistics, chi-square test, Mann Whitney test, Independent Samples t-test and Shapiro Wilk test. RESULTS: At the time of the survey, 80.2% (n = 324) had been screened within three years (ADHERENT), 5.9% (n = 24) had exceeded the three-year frequency (NON-ADHERENT) while 13.9% (n = 56) never had a mammogram. No significant associations were found between ADHERENT or NON-ADHERENT women in relation to sociodemographic or health status variables (p > 0.05). Knowledge of screening frequency was significantly associated with women's mammography adherence (χ2 = 5.5, p = 0.020). Health beliefs were the strongest significant predictors to describe the variance between ADHERENT and NON-ADHERENT screeners. When Mann Whitney test and Independent Samples t-test were applied on mammography adherence, perceived barriers and cues to action were found to be the most important predictors (p = 0.000, p = 0.039 respectively). CONCLUSIONS: To increase routine and timely mammography practices, women who are non-adherent to recommended time frequency guidelines should be targeted, together with their health beliefs, predominantly perceived barriers and cues to action.

PURPOSE: While advance care planning holds promise, uptake is variable and it is unclear how well people engage with or comprehend advance care planning. The objective of this study was to explore how people with cancer comprehended advance care plans and examine how accurately advance care planning documentation represented patient wishes. METHODS: This study used a qualitative descriptive design. Data collection comprised interviews and an examination of participants' existing advance care planning documentation. Participants included those who had any diagnosis of cancer with an advance care plan recorded: Refusal of Treatment Certificate, Statement of Choices, and/or Enduring Power of Attorney (Medical Treatment) at one cancer treatment centre. RESULTS: Fourteen participants were involved in the study. Twelve participants were female (86%). The mean age was 77 (range: 61-91), and participants had completed their advance care planning documentation between 8 and 72 weeks prior to the interview (mean 33 weeks). Three themes were evident from the data: incomplete advance care planning understanding and confidence, limited congruence for attitude and documentation, advance care planning can enable peace of mind. Complete advance care planning understanding was unusual; most participants demonstrated partial comprehension of their own advance care plan, and some indicated very limited understanding. Participants' attitudes and their written document congruence were limited, but advance care planning was seen as helpful. CONCLUSIONS: This study highlighted advance care planning was not a completely accurate representation of patient wishes. There is opportunity to improve how patients comprehend their own advance care planning documentation.

BACKGROUND: Neonatal deaths are often associated with the complex decision to limit or withdraw life-sustaining interventions (LSIs) rather than therapeutic impasses. Despite the existence of a law, significant disparities in clinical procedures remain. This study aimed to assess deaths occurring in a Neonatal Intensive Care Unit (NICU) and measure the impact of a traceable Limitation or Withdrawal of Active Treatment (LWAT) file on the treatment of these newborns. METHODS: In this monocentric retrospective study, we reviewed all consecutive neonatal deaths occurring during two three-year periods among patients in the NICU at the North Hospital of Marseille: cohort 1 (from 2009 to 2011 without the LWAT file) and cohort 2 (from 2013 to 2015 after introduction of the LWAT file). Newborns included were: gestational age over 22 weeks, birth weight over 500 g, and admission and death in the same NICU. Deaths were categorized according to the classification described by Verhagen et al.: 1) children who died despite cardiopulmonary resuscitation (CPR) (no withholding nor withdrawing of LSIs), (2) children who died while the ventilator, without CPR (no withdrawing of LSIs, but CPR withheld), (3) children who died after LSIs were withdrawn, or (4) LSIs were withheld. RESULTS: 193 deaths were analyzed: 77 in cohort 1 and 116 in cohort 2. 50% of deaths followed the decision to limit or stop life-sustaining interventions. The mean age at death did not differ between the two cohorts (p = 0.525). An increase in the mortality rate after life-sustaining interventions were withdrawn was observed. The number of multidisciplinary decision meetings was statistically higher in cohort 2 (32.5% versus 55.2% p = 0.002), which were most often prompted due to neurological pathologies, with an increase in parental advice concerning the management of their child (p = 0.026). Even if the introduction of this file did not have an effect on patient age at death, it was significantly associated with a better understanding of end-of-life conditions (p = 0.019), including medication used to sedate and comfort the patient. CONCLUSIONS: Introduction of the LWAT file seems imperative to develop a personalized healthcare strategy for each child and situation.

Some authors have questioned the moral authority of advance directives (ADs) in cases in which it is not clear if the author of the AD is identical to the person to whom it later applies. This article focuses on the question of whether the latest results of neuroimaging studies have moral significance with regard to the moral authority of ADs in patients with disorders of consciousness (DOCs). Some neuroimaging findings could provide novel insights into the question of whether patients with DOCs exhibit sufficient psychological continuity to be ascribed diachronic personal identity. If those studies were to indicate that psychological continuity is present, they could justify the moral authority of ADs in patients with DOCs. This holds at least if respect for self-determination is considered as the foundation for the moral authority of ADs. The non-identity thesis in DOCs could no longer be applied, in line with clinical and social practice.

PURPOSE OF REVIEW: The aim of this review is to examine literature relating to the withdrawal of life-sustaining therapy (WLST). RECENT FINDINGS: Discussions regarding end-of-life issues in adults and children are not occurring comprehensively. Discussions relating to the WLST in the pediatric population varies by institution and may vary by race, age, health insurance, diagnosis, and severity of illness. Completing advance directives prior to placement of life-sustaining treatments is not consistent practice. With the WLST, differences in perspectives exist between medical specialties, within one specialty at different levels of training, and in physicians' ethical and psychological responses to the WLST. The timing of WLST appears to be influenced by ICU strain and communication issues. Study outcomes differ regarding the functionally favorable survival of patients who have had WLST. Universal guidelines for the WLST may not address individual patient circumstances. SUMMARY: Discussions of end-of-life issues early in the course of a patient's health care will contribute to the healthcare team's understanding and respect of the patient's wishes. This article addresses the withdrawal of left ventricular assist devices; attending physicians and physicians in training perspectives of WLST; do physicians distinguish between withholding and WLST; the timing of WLST; guidelines for the process of WLST; and pediatrics and end-of-life decisions.

BACKGROUND: Many hospitalized adults do not have the capacity to make their own health care decisions and thus require a surrogate decision-maker. While the ethical standard suggests that decisions should focus on a patient's preferences, our study explores the principles that surrogates consider most important when making decisions for older hospitalized patients. OBJECTIVES: We sought to determine how frequently surrogate decision-makers prioritized patient preferences in decision-making and what factors may predict their doing so. DESIGN AND PARTICIPANTS: We performed a secondary data analysis of a study conducted at three local hospitals that surveyed surrogate decision-makers for hospitalized patients 65 years of age and older. MAIN MEASURES: Surrogates rated the importance of 16 decision-making principles and selected the one that was most important. We divided the surrogates into two groups: those who prioritized patient preferences and those who prioritized patient well-being. We analyzed the two groups for differences in knowledge of patient preferences, presence of advance directives, and psychological outcomes. KEY RESULTS: A total of 362 surrogates rated an average of six principles as being extremely important in decision-making; 77.8% of surrogates selected a patient well-being principle as the most important, whereas only 21.1% selected a patient preferences principle. Advance directives were more common to the patient preferences group than the patient well-being group (61.3% vs. 44.9%; 95% CI: 1.01-3.18; p = 0.04), whereas having conversations with the patient about their health care preferences was not a significant predictor of surrogate group identity (81.3% vs. 67.4%; 95% CI: 0.39-1.14; p = 0.14). We found no differences between the two groups regarding surrogate anxiety, depression, or decisional conflict. CONCLUSIONS: While surrogates considered many factors, they focused more often on patient well-being than on patient preferences, in contravention of our current ethical framework. Surrogates more commonly prioritized patient preferences if they had advance directives available to them.

Metabolic syndrome (MetS), conventionally defined by the presence of at least three out of five dismetabolic traits (abdominal obesity, hypertension, low plasma HDL-cholesterol and high plasma glucose and triglycerides), has been associated with both breast cancer (BC) incidence and prognosis. We investigated the association between the prevalence of MetS and a score of adherence to the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) recommendations for the prevention of cancer in a cross-sectional study of BC patients. The DIet and ANdrogen-5 study (DIANA-5) for the prevention of BC recurrences recruited 2092 early stage BC survivors aged 35-70. At recruitment, all women completed a 24-hour food frequency and physical activity diary on their consumption and activity of the previous day. Using these diaries we created a score of adherence to five relevant WCRF/AICR recommendations. The prevalence ratios (PRs) and 95% confidence intervals (CIs) of MetS associated with the number of recommendations met were estimated using a binomial regression model. The adjusted PRs of MetS decreased with increasing number of recommendations met (p < 0.001). Meeting all the five recommendations versus meeting none or only one was significantly associated with a 57% lower MetS prevalence (95% CI 0.35-0.73). Our results suggest that adherence to WCRF/AICR recommendations is a major determinant of MetS and may have a clinical impact.

OBJECTIVES: Conflict is common between physicians and surrogate decision makers around end-of-life care in ICU. Involving experts in conflict management improve outcomes, but little is known about what differences in conflict management styles may explain the benefit. We used simulation to examine potential differences in how palliative care specialists manage conflict with surrogates about end-of-life treatment decisions in ICUs compared with intensivists. DESIGN: Subjects participated in a high-fidelity simulation of conflict with a surrogate in an ICU. In this simulation, a medical actor portrayed a surrogate decision maker during an ICU family meeting who refuses to follow an advance directive that clearly declines advanced life-sustaining therapies. We audiorecorded the simulation encounters and applied a coding framework to quantify conflict management behaviors, which was organized into two categories: task-focused communication and relationship building. We used negative binomial modeling to determine whether there were differences between palliative care specialists' and intensivists' use of task-focused communication and relationship building. SETTING: Single academic medical center ICU. SUBJECTS: Palliative care specialists and intensivists. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We enrolled 11 palliative care specialists and 25 intensivists. The palliative care specialists were all attending physicians. The intensivist group consisted of 11 attending physicians, 9 pulmonary and critical care fellows, and 5 internal medicine residents rotating in the ICU. We excluded five residents from the primary analysis in order to reduce confounding due to training level. Physicians' mean age was 37 years with a mean of 8 years in practice. Palliative care specialists used 55% fewer task-focused communication statements (incidence rate ratio, 0.55; 95% CI, 0.36-0.83; p = 0.005) and 48% more relationship-building statements (incidence rate ratio, 1.48; 95% CI, 0.89-2.46; p = 0.13) compared with intensivists. CONCLUSIONS: We found that palliative care specialists engage in less task-focused communication when managing conflict with surrogates compared with intensivists. These differences may help explain the benefit of palliative care involvement in conflict and could be the focus of interventions to improve clinicians' conflict resolution skills.

Dementia patients may express wishes that do not conform to or contradict earlier expressed preferences. Our understanding of the difference between their prior preferences and current wishes has important consequences for the way we deal with advance directives. Some bioethicists and gerontologists have argued that dementia patients change because they undergo a 'response shift'. In this paper we question this assumption. We will show that proponents of the response shift use the term imprecisely and that response shift is not the right model to explain what happens to dementia patients. We propose a different explanation for the changed wishes of dementia patients and conclude that advance directives of dementia patients cannot be simply put aside.

AIM: The aim of this study was to evaluate adherence to an intervention optimizing in-hospital monitoring practice, by introducing early warning scoring (EWS) of vital parameters. BACKGROUND: Interventions comprising EWS systems reduce in-hospital mortality, but evaluation of adherence to such interventions is required to correctly interpret interventional outcome. METHOD: Adherence was evaluated with a mixed-methods approach. Quantitative data, obtained pre-interventionally (2009) and postinterventionally (2010 and 2011), were used to calculate and compare time intervals between scorings of vital parameters. Semi-structured interviews were used to evaluate the implementation process. RESULTS: We found significant reductions in time intervals between measurements of vital parameters in 2011 compared to 2009. Scorings of vital parameters were repeated within 8 hours in 71-77% of patients scoring total modified EWS levels of 0, 2 or 4. The theme Motivation by clinical relevance and meaningfulness was identified as crucial to the implementation process. CONCLUSION: High adherence to an intervention may be strongly related to nurses' perceived clinical relevance of the intervention.

Physicians who allow a suicide attempt to happen, which from an ex ante viewpoint was completely voluntary, cannot be held punishable for homicide or failing to provide medical assistance when the suicide corresponds to the putative will of the patient according to plausible information supplied by an authorized person with healthcare proxy. Guidelines for resuscitation also play a central role in the forensic practice for assessment of whether and when resuscitation can be terminated; therefore, it is urgently advised to follow and implement these guidelines: deviations are possible if they can be factually justified. The currently declared will of a Jehovah's Witness to refuse an allogeneic blood transfusion is binding for the physician. If the patient does not have the ability to reason at the decisive time for evaluating the indications for a blood transfusion and an advance directive has been made, this directive is the guiding principle for medical actions. If such a directive is not available, the putative will must be elucidated. If this is not possible, the objective welfare of the patient must be upheld and the blood transfusion carried out (in dubio pro vita).

BACKGROUND: Perioperative care demands consideration of individual treatment goals. We evaluated the attitudes of medical staff towards a short standardized advance directive (SSAD) as a means of improving patient-orientated care at the transition from operating theater to general or intensive care wards. METHOD: Multicenter anonymized standardized multiple-choice questionnaire among physicians and nurses from various operative and anesthesiology departments. Questions addressing demographic parameters and attitudes towards advance directives in acute care settings (eleven 4stepped Likert items). Univariate analysis of group comparisons using the chi-square and Kruskal-Wallis rank-sum test. Multivariable analysis of significant differences employing ordinal logistic regression. RESULTS: The overall return rate was 28.2 % (169 questionnaires). Of these, 19.5 % said that existing advance directives were regularly reassessed preoperatively. SSAD was expected to provide improved emergency care by 82.3 and 76.6 % thought that it would help to better focus intensive care resources according to patients' needs. DISCUSSION: Our study shows the dilemma of insufficiently structured directives for changing treatment goals as well as a high number of legal procedures to obtain proxy decisions due to missing out-patient advance health planning. From a medical staff perspective there is strong support for the concept of SSAD based on medical, ethical, economic and organizational reasons.

We argue that an advance directive (AD) is not invalidated by personality changes in dementia, as is claimed by Rebecca Dresser. The claim is that a new person results under such personality changes, and that the former person cannot write an AD for the new person. After stating the argument against ADs in cases of dementia, we provide a detailed examination of empirical studies of personality changes in dementia. This evidence, though not strong due mainly to low sample sizes and different notions of personal identity, does not support Dresser's position. Given the weakness in the empirical evidence, we turn to a philosophical defense of ADs based on a social contract view supporting the current interests of those writing ADs. Additionally, we argue that personality change is not equivalent to change in personal identity, as would be required by the argument against ADs in cases of dementia.

Advance directives (ADs) have been hailed for two decades as the best way to safeguard patients' autonomy when they are totally or partially incompetent. In many national contexts they are written into law and they are mostly associated with end-of-life decisions. Although advocates and critics of ADs exchange relevant empirical and theoretical arguments, the debate is inconclusive. We argue that this is so for good reasons: the ADs' project is fraught with tensions, and this is the reason why they are both important and deeply problematic. We outline six such tensions, and conclude with some positive suggestions about how to better promote patients' autonomy in end-of-life decision. We argue that ADs should continue to be an option but they cannot be the panacea that they are expected to be.
