Advance directives in Spain. Perspectives from a medical bioethicist approach

Advance Care Planning in Spain

In the last decade in Spain, an important push has been given to the development of health policies that define the framework of action in the care of people with advanced chronic diseases. Respect for the autonomy of the patient, shared decision-making processes and advance care planning (ACP) are recognized into health plans as a key aspect in chronic care, frailty, and palliative care. A few but significant number of institutions, local governments, and healthcare professionals from different regions of Spain have started a rationale and roadmap for a new twist in Spain's theoretical, ethical and policy development, promoting ACP implementation into public health care systems. In 2020, a working group founded in 2017, evolved into the "Spanish Association of Shared Care Planning" (AEPCA). The Shared Care Planning (SCP) concept grows up after the two international consensus Delphi studies in 2017 and pretends to shift from the framework of ACP programs to a person-centred care approach. In the last years, several experiences show how professionals are more sensible and interested on the ACP process, but it cannot be said, for now, that it has taken effect in the global Spanish health system. Even both ACP and SCP are being used simultaneously in Spain, each day more people and autonomous communities embrace renewed concept and foundations of SCP, supporting the work of AEPCA on spreading the value of this process into the care of people who are coping with chronic diseases, vulnerability, and frailty.

End-of-Life Planning Depends on Socio-Economic and Racial Background: Evidence from the US Health and Retirement Study (HRS)

CONTEXT

Americans express a strong preference for participating in decisions regarding their medical care, yet they are often unable to participate in decision-making regarding their end-of-life care.

OBJECTIVE

To examine determinants of end-of-life planning; including, the effect of an individual's ageing and dying process, health status and socio-economic and racial/ethnic background.

METHODS

US observational cohort study, using data from the Health and Retirement Study (1992 - 2014) including 37,494 individuals. Random-effects logistic regression analysis was used to examine the relationship between the presence of a living will and a range of individual time-varying characteristics, including time to death, and several time-invariant characteristics.

RESULTS

End-of-life planning depends on several patient characteristics and circumstances, with socio-economic and racial/ethnic background having the largest effects. The probability of having a living will rises sharply late in life, as we would expect, and is further modified by the patient's proximity to death. The dying process, exerts a stronger influence on end-of-life planning than does the aging.

CONCLUSIONS

Understanding differences that increase end-of-life planning is important to incentivize patients' participation. Advance planning should be encouraged and accessible to people of all ages as it is inevitable for the provision of patient-centered and cost-effective care.

Advance directives and real-world end-of-life clinical practice: a case-control study

BACKGROUND

Advance directives (ADs) have been legally regulated to promote autonomy over health decisions among patients who later lose decision-making capacity.

AIMS AND OBJECTIVES

To analyse the differences in clinical practice at end of life among people who had completed an AD versus those who had not.

METHODS

Retrospective case-control study (1:2), matched by age, sex, year, cause of death and region of residence. The data sources used were the ADs registry, central registry of insured persons, hospital discharge, pharmacy and billing databases, and the mortality registry. Conditional logistic regression models (crude and adjusted by socioeconomic level) were performed. The outcome variable was the frequency of medical procedures performed during the last year of life.

RESULTS

1723 people with ADs who died in Catalonia during 2014-2015 were matched with 3446 dead controls (without ADs). Thoracentesis was the procedure with the greatest reduction among women with an AD (adjusted OR (ORadj) 0.54, 95% CI: 0.32 to 0.89) in conjunction with artificial nutrition (ORadj 0.54, 95% CI: 0.31 to 0.95). Intubation was the procedure with the greatest reduction (ORadj 0.56, 95% CI: 0.33 to 0.94) among men. Slight differences could be seen in the case of cancer deaths. There were no relevant differences when adjusting by socioeconomic level.

CONCLUSIONS

ADs are an effective tool to adjust the realisation of some procedures at end of life. These results can help better plan for the treatment of patients with ADs, as well as increase the awareness among clinical personnel, families and the general population.

The Use of Advance Directives in Specialized Care Units: A Focus Group Study With Healthcare Professionals in Madrid

Eight focus groups were conducted in four public hospitals in Madrid to explore healthcare professionals' perceptions of advance directives (ADs) in order to improve the understanding of their lack of success among physicians and patients. A purposive sample of sixty healthcare professionals discussed ADs and reasons for their infrequent use. Three main themes were identified: perceptions about their meaning, appraisals of their use in clinical practice, and decision-making about them. Healthcare professionals perceived a lack of clarity about their definition and implementation. There is insufficient awareness of their efficacy in improving the quality of clinical relationships and decision-making, and they are often perceived only as a bureaucratic procedure. Advance directives are not integrated in the clinical practice of Madrid's healthcare specialist services because their application is exceedingly complex, because of insufficient education about them (for both professionals and citizens), and because of lack of procedural clarity. Consequently, healthcare professionals are not aware of how ADs could improve clinical decision-making, of when and for whom their use is appropriate, and of who has responsibility for providing ADs-related information to patients. These circumstances contribute to patients' lack of interest in completing these documents and to physicians' sceptical views about their usefulness.

What do Galicia's nurses know about living wills?

OBJECTIVE

To analyse the level of knowledge and attitudes concerning living wills of nurses working in 3 hospitals of Servizo Galego de Saúde (Spain).

METHOD

Descriptive, cross-sectional, multi-centre study. Stratified sampling was carried out with nurses from the University Hospital Complexes of Ourense, Ferrol and Vigo. A sample size of 239 individuals was calculated. The data was collected during the first semester of 2018 using a validated self-administered questionnaire («Cuestionario de conocimientos y actitudes de los profesionales sanitarios en el proceso de declaración de voluntades vitales»).

RESULTS

A total of 262 nurses participated. Fifty percent believe that health professionals are obliged to inform about living wills. Two percent consider that they have enough information on the subject, and this is demonstrated in the knowledge questions, where between 61%-93% fail in the questions related to the documentation, use, and their legal aspects. Eighty-four percent consider that they have the obligation to uphold the values and beliefs of patients, and 89% that patients have the right to receive and decide on the right care. Thirteen percent consider that patients are not well informed about living wills, and 83% would recommend to chronic patients that they complete a living will.

CONCLUSIONS

Nurses have a great lack of knowledge about the legal aspects and the use of living wills, which makes them feel unable to inform their patients about them. Despite of the lack of knowledge, their attitude is positive and most of them state that they would recommend them to their patients.

What are the ethical questions raised by the integration of intensive care into advance care planning?

A major goal of intensive care units (ICUs) is to offer optimal management, but for many patients admitted to the ICU, they are unlikely to yield any lasting benefit. In this context, the ICU physician remains a key intermediary, particularly when a decision regarding possible limitation or withdrawal of life-sustaining therapy becomes necessary. The possibility of admission to the ICU, and the type of care the patient would like to receive there, should be integrated into the healthcare project in agreement with the patient, regardless of the stage of disease that the patient suffers from. These dispositions should be recorded in the patient's file, and should respect the progressive nature of both the disease itself, and the discussions necessary in such complex situations. The ICU physician can serve as a valuable consultant for the treating physician, in particular to guide patient choices when formalizing their healthcare preferences in the form of advance care planning (ACP) or advance directives (AD). Ideally, the best time to address this issue is before the patient's clinical situation deteriorates towards an acute emergency, and providing complete and transparent information to inform the patient's choices.

Impact of a stay in the intensive care unit on the preparation of Advance Directives: Descriptive, exploratory, qualitative study

BACKGROUND

Our objective was to assess, through a qualitative, exploratory study, the thought processes of patients regarding the formulation of advance directives (AD) after a stay in the ICU.

METHODS

The study was conducted from May to July 2016 using telephone interviews performed by four senior ICU physicians. Inclusion criteria were: patients discharged from ICU to home>3 months earlier. Semi-directive interviews with patients focused on 5 main points surrounding AD.

RESULTS

In total, among 159 eligible patients, data from 94 (59%) were available for analysis. Among all those interviewed, 83.5% had never heard of "advance directives". Only 2% had executed AD before ICU admission, and 7% expressed a desire to prepare AD further to their ICU stay. Among the barriers to preparation of AD, lack of information was the main reason cited for not executing AD. Patients noted the following in their AD: withdrawal of life-support in case of vegetative/minimally conscious state or when there is no longer any hope, in case of uncontrollable pain, and if impossible to wean from mechanical ventilation.

CONCLUSION

The ideal time to engage patients in these discussions is most likely well before an acute health event occurs, although this warrants further investigation both before and after ICU admissions.

Are advance directives helpful for good end of life decision making: a cross sectional survey of health professionals

Background

This paper joins the debate over changes in the role of health professionals when applying advance directives to manage the decision-making process at the end of life care. Issues in relation to advance directives occur in clinical units in Lithuania; however, it remains one of the few countries in the European Union (EU) where the discussion on advance directives is not included in the health-care policy-making agenda. To encourage the discussion of advance directives, a study was designed to examine health professionals’ understanding and preferences related to advance directives. In addition, the study sought to explore the views of health care professionals of the application of Advance Directives (AD) in clinical practice in Lithuania.

Methods

A cross-sectional survey was conducted by interviewing 478 health professionals based at major health care centers in Kaunas district, Lithuania. The design of the study included the use of a questionnaire developed for this study and validated by a pilot study. The collected data were analyzed using standard descriptive statistical methods.

Results

The analysis of knowledge about AD revealed some statistically significant differences when comparing the respondents’ profession and gender. The analysis also indicated key emerging themes among respondents including tranquility of mind, the longest possible life expectancy and freedom of choice.

Further, the study findings revealed that more than half of the study participants preferred to express their will while alive by using advance directives.

Conclusions

The study findings revealed a low level of knowledge on advance directives among health professionals. Most health professionals agreed that AD’s improved end-of-life decision making while the majority of physicians appreciated AD as the best tool for sharing responsibilities in clinical practice in Lithuania. More physicians than nurses preferred the presence of advance directives to support their decision making in end-of-life situations.

[Validation of the knowledge and attitudes of health professionals in the Living Will Declaration process]

OBJECTIVE

Evaluate the validity and reliability of the knowledge and attitudes of health professionals questionnaire on the Living Will Declaration (LWD) process.

DESIGN

Cross-sectional study structured into 3 phases: (i)pilot questionnaire administered with paper to assess losses and adjustment problems; (ii)assessment of the validity and internal reliability, and (iii)assessment of the pre-filtering questionnaire stability (test-retest).

LOCATION

Costa del Sol (Malaga) Health Area. January 2014 to April 2015.

PARTICIPANTS

Healthcare professionals of the Costa del Sol Primary Care District and the Costa del Sol Health Agency. There were 391 (23.6%) responses, and 100 participated in the stability assessment (83 responses).

MAIN MEASUREMENTS

The questionnaire consisted of 2 parts: (i)Knowledge (5 dimensions and 41 items), and (ii)Attitudes (2 dimensions and 17 items).

RESULTS

In the pilot study, none of the items lost over 10%. In the evaluation phase of validity and reliability, the questionnaire was reduced to 41 items (29 of knowledge, and 12 of attitudes). In the stability evaluation phase, all items evaluated met the requirement of a kappa higher than 0.2, or had a percentage of absolute agreement exceeding 75%.

CONCLUSIONS

The questionnaire will identify the status and areas for improvement in the health care setting, and then will allow an improved culture of LWD process in general population.

[Social-health characteristics of subjects who make a living will]

INTRODUCTION

The Living Will (LW) is well publicised, and still largely unknown to the general public and health professionals.

OBJECTIVE

To describe the characteristics of the subjects that formalize a LW related to socio-demographic situation, health status, degree of dependence, healthcare characteristics and psychosocial aspects.

METHOD

Descriptive observational study conducted in the Health Area of Albacete including 123 people who formalized the LW in a Will Register in 2011. Study variables included: self-perceived health, functional status, morbidity, socio-demographic characteristics, use of health services, attitudes towards the LW, and psychosocial aspects.

RESULTS

Those that made an LW, were mainly women (64.2%), had a mean age of 53.3 years (SD: 14.5), higher levels of education (61% with at least secondary education), and a lifestyle other than living with a partner, and with children (67.5%). The majority were self-sufficient for their daily living activities (98.4% to 94.3% for basic and instrumental), and suffered from chronic disease (73.2%). Despite lasting relationships with their physicians (9.4 years; SD: 7.9), there was very little talk about the end of life (18.3%). More than a half had a family member who had previously signed a document (54.5%). More than two-thirds (68.5%) considered this document useful in the death of a relative, and also a 56.7% had also served as a caregiver of a terminal patient.

CONCLUSIONS

Middle-aged people, predominantly women, formalized an LW most often. They are usually chronic, but self-sufficient for their daily living activities, and are convinced that they can influence their health situation.

Study of the factors influencing the preparation of advance directives

The aim of the study is to analyze the factors influencing the decision to prepare advance directives (AD) related to socio-demographic situation, health status, degree of dependence, healthcare characteristics and psychosocial aspects. This is a case-control study conducted using a personal interview. We compared 123 subjects who had completed AD with 123 subjects who had not and who belonged to two health centers in the Albacete Health District. Study variables included self-perceived health, functional status, morbidity, socio-demographic characteristics, use of health services, attitudes toward AD and psychosocial aspects. We found a predominance of women (64.2%) among those who prepared AD, with a mean age of 53.3 years. Preparing AD was associated with secondary or higher education (OR=2.5), a lifestyle other than living with a partner and with children (OR=2.5), chronic medication use (OR=3.2), higher than average number of specialist visits (OR=4.0), a longer-term relationship with the family physician (OR=3.5), a family history of having AD (OR=17.3) and with lower levels of social interaction (OR=3.0). The results suggest that several factors, resulting from both the socio-demographic situation and health or functional status, can affect the decision to formalize AD.

End-of-life decisions: a cross-national study of treatment preference discussions and surrogate decision-maker appointments

BACKGROUND

Making treatment decisions in anticipation of possible future incapacity is an important part of patient participation in end-of-life decision-making. This study estimates and compares the prevalence of GP-patient end-of-life treatment discussions and patients' appointment of surrogate decision-makers in Italy, Spain, Belgium and the Netherlands and examines associated factors.

METHODS

A cross-sectional, retrospective survey was conducted with representative GP networks in four countries. GPs recorded the health and care characteristics in the last three months of life of 4,396 patients who died non-suddenly. Prevalences were estimated and logistic regressions were used to examine between country differences and country-specific associated patient and care factors.

RESULTS

GP-patient discussion of treatment preferences occurred for 10%, 7%, 25% and 47% of Italian, Spanish, Belgian and of Dutch patients respectively. Furthermore, 6%, 5%, 16% and 29% of Italian, Spanish, Belgian and Dutch patients had a surrogate decision-maker. Despite some country-specific differences, previous GP-patient discussion of primary diagnosis, more frequent GP contact, GP provision of palliative care, the importance of palliative care as a treatment aim and place of death were positively associated with preference discussions or surrogate appointments. A diagnosis of dementia was negatively associated with preference discussions and surrogate appointments.

CONCLUSIONS

The study revealed a higher prevalence of treatment preference discussions and surrogate appointments in the two northern compared to the two southern European countries. Factors associated with preference discussions and surrogate appointments suggest that delaying diagnosis discussions impedes anticipatory planning, whereas early preference discussions, particularly for dementia patients, and the provision of palliative care encourage participation.

Stability over time in the preferences of older persons for life-sustaining treatment

OBJECTIVE

To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability.

DESIGN

Longitudinal cohort study.

SETTING

Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later.

RESULTS

86 percent of the patients did not change preferences. Sex, age, marital status, hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did.

CONCLUSION

Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning.

A critical review of advance directives in Germany: attitudes, use and healthcare professionals' compliance

OBJECTIVE

Recent legal changes in Germany make non-compliance with advance directives (ADs) a criminal offence. This article assesses the evidence on attitudes towards, use of, and physician compliance with ADs in Germany.

METHODS

Critical review: studies on ADs, identified from a systematic review of culture and end-of-life care in Germany (11 electronic databases, 3 journals, reference lists, and grey literature), were included. An interpretative synthesis of findings revealed cross-cutting themes.

RESULTS

Thirty-two studies (1996-2009) were identified. Key themes were: awareness; utilization; compliance; and bindingness of ADs. There was a positive trend between awareness of ADs and study publication date. Use varied between patient groups (0.3-62%) and was low amongst the general population (2.5-10%). Fears about ADs' purpose and possible abuse were identified. Physician discomfort in discussing ADs and non-compliance were reported. Physicians preferred legally binding ADs, though conflicting results were reported for patients' desired level of bindingness.

CONCLUSION

Although there is increasing awareness of ADs in Germany, there remains low use, poor communication, fears of abuse, some non-compliance and contradictory evidence regarding desired bindingness.

PRACTICAL IMPLICATIONS

Although legal changes will hopefully improve compliance, low awareness, communication difficulties and uncertainties surrounding ADs must be addressed if use is to increase.

Culture and end of life care: a scoping exercise in seven European countries

AIM

Culture is becoming increasingly important in relation to end of life (EoL) care in a context of globalization, migration and European integration. We explore and compare socio-cultural issues that shape EoL care in seven European countries and critically appraise the existing research evidence on cultural issues in EoL care generated in the different countries.

METHODS

We scoped the literature for Germany, Norway, Belgium, The Netherlands, Spain, Italy and Portugal, carrying out electronic searches in 16 international and country-specific databases and handsearches in 17 journals, bibliographies of relevant papers and webpages. We analysed the literature which was unearthed, in its entirety and by type (reviews, original studies, opinion pieces) and conducted quantitative analyses for each country and across countries. Qualitative techniques generated themes and sub-themes.

RESULTS

A total of 868 papers were reviewed. The following themes facilitated cross-country comparison: setting, caregivers, communication, medical EoL decisions, minority ethnic groups, and knowledge, attitudes and values of death and care. The frequencies of themes varied considerably between countries. Sub-themes reflected issues characteristic for specific countries (e.g. culture-specific disclosure in the southern European countries). The work from the seven European countries concentrates on cultural traditions and identities, and there was almost no evidence on ethnic minorities.

CONCLUSION

This scoping review is the first comparative exploration of the cultural differences in the understanding of EoL care in these countries. The diverse body of evidence that was identified on socio-cultural issues in EoL care, reflects clearly distinguishable national cultures of EoL care, with differences in meaning, priorities, and expertise in each country. The diverse ways that EoL care is understood and practised forms a necessary part of what constitutes best evidence for the improvement of EoL care in the future.

New regulation of the right to a dignified dying in Spain: repercussions for nursing

Preserving dignity during the dying process requires reviewing the roles of those involved in the treatment, care methods and decision-making. This article examines the participation and responsibility assigned to nurses regarding decision-making in the final stages of life, as laid out in the Rights to and Guarantee of Dignity for the Individual During the Process of Death Act. This text has been analysed on the levels of socio-cultural practice and discourse practice, using the critical discourse analysis methodology. The results show that, although the law is another result of the social trend of patient empowerment, the responsibility of the nurses is not recognised, and they are left out of the decision-making process in the final stages of life.

[Knowledge and attitude regarding previous instructions for the patients of a public hospital of Madrid]

INTRODUCTION

The level of knowledge and attitudes of patients towards the previous instructions is a little known subject given that their introduction in the Community of Madrid (CM) is recent.

AIMS

To assess the level of knowledge and implementation of advance directives in patients admitted to an Internal Medicine Service of a public hospital in the CM, the attitudes of patients regarding these documents and their correlation with demographic variables.

PATIENTS AND METHODS

A cross-sectional study through structured survey of opinion, closed and voluntarily given to all patients admitted in the Internal Medicine Unit of the University Hospital Alcorcon Foundation on the dates May 20 and June 3, 2008 was carried out.

RESULTS

A total of 155 patients were included, the questions being answered by the patients per se by 57% and by members of theirs families in 42%. Mean age of the patients was 77 years, 50.9% were male and 86.45% were Catholic. Only 7 patients (4.5%) knew what the advance directives were and only one patient had done them. On learning of their existence, 49 patients (31.6%) would like to do the advance instructions. Of the respondents, 80.6% were in favor of having the advance directives document in their medical history and 72.9% do not believe that having these advance directives would change the attitude of their doctor.

CONCLUSIONS

Although the regulation of advance directives in the Community of Madrid has already been in force for 5 years, little is known about these documents and they are still in a period of diffusion.

[Dying with dignity. A study of living wills]

OBJECTIVE

To describe the profile of persons who exercise their right to draw up a living will, to analyze physicians' knowledge of living wills and attitudes toward them, and to compare the regulations pertaining to this right in the distinct autonomous regions of Spain.

METHOD

A descriptive study that included an analysis of a systematic sample of 931 living wills registered in the autonomous region of Valencia (Spain), a self-administered structured questionnaire administered to a sample of 84 physicians working in emergency departments and intensive care units (45% response rate), and a comparison of the regional legislation covering living wills.

RESULTS

A total of 1.6% of inhabitants aged 16 or over had registered a living will (female/male ratio: 1.8/1). Most (73.8%) used a standard document drawn up by a particular religious faith. The most common reasons for writing a living will were to limit therapeutic efforts (99%) and obtain pain-relieving drugs (98%). Although 61 physicians (72.6%) frequently attended the terminally ill, only 6% consulted the register of living wills in these situations and 28% did not know how to consult this register. There is wide variation among regions in the minimum age for registering a living will, in the procedure to be followed if the signer is pregnant, in designating a person as having the authority to make a living will, and in the number of registration points available to deposit living wills.

CONCLUSIONS

Most persons registering a living will are healthy individuals with a particular religious faith who reject certain treatments. Most health professionals do not check whether critically ill patients have made a living will. Exercising the rights contained in living wills is complicated by the diversity of criteria among different regions.

Interventions to promote the use of advance directives: an overview of systematic reviews

OBJECTIVE

To identify, appraise and synthesise the results of systematic reviews of the literature (SRLs) that examines the effectiveness of interventions to increase advance directive (AD) completion rate.

METHODS

Narrative review of the literature-an overview of SRLs focused on interventions to improve patients' AD completion rate.

RESULTS

Seven SRLs were located. A wide range of interventions was identified in order to determine their influence on the AD completion rate.

CONCLUSION

The most effective method of increasing the use of ADs is the combination of informative material and repeated conversations over clinical visits. The use of passive informative material in isolation does not significantly increase AD completion rates. However, when interactive informative interventions are employed, the AD completion rate increases and the majority of the studies identify multiple sessions as the most effective method for direct interaction between patients and health care professionals.

PRACTICE IMPLICATIONS

The progressive ageing of the population and the provision of quality care during the process of ageing and dying, have given rise to the Governments' interest in developing moral autonomy and regulating tools as ADs. In order to put legislation into practice it is necessary to set up successful interventions to expand ADs use.

[COPD. A model for using advanced directives and care planning]

Decision-making in COPD is complicated by the lack of clear prognostic factors. In this clinical situation it is also necessary to include the desires, values and choices of patients. The problem is more complex in the critical episodes, where the patients are incapable to make decisions. The instruments that allow incapable patients to represent themselves, the kind of patients who could benefit from its use, and the Spanish legislation on the matter, are presented in the first part of the work. The paper goes on to explain how to apply advance directives to the case of COPD. The article concludes that the appropriate use of advance directives and advanced care planning increases the quality of decisions at the end of the life of the patients with COPD."

Advance Directives and Proxies' Predictions About Patients' Treatment Preferences

The accuracy of proxies when they interpret advance directives or apply substituted decision-making criteria has been called into question. It therefore became important to know if the Andalusian Advance Directive Form (AADF) can help to increase the accuracy of proxies' predictions. The aim of this research was to compare the effect of the AADF on the accuracy of proxies' predictions about patients' preferences with that gained from informative and deliberative sessions about end-of-life decision making. A total of 171 pairs of patients and their proxies were randomized to three groups. The control group's answers to the Life Sustaining Preferences Questionnaire (LSPQ) were compared with their proxies' answers to the same questionnaire. In one intervention group, the patients had already completed the AADF and given it to their proxies, who used it to guide their own answers to the LSPQ. In the second intervention (discussion) group, both patients and proxies attended two educative sessions guided by trained nurses and later filled in the LSPQ. Comparisons of accuracy and other variables showed a strong association with the discussion group. The findings show that promoting communication between patients and their proxies improves the accuracy of proxies' predictions much more than isolated use of the AADF form.
