Quality of life and depression in patients with amyotrophic lateral sclerosis - does the country of origin matter?

BACKGROUND: Given the inevitable relentless progressing nature of amyotrophic lateral sclerosis (ALS), it is essential to identify factors influencing patients' wellbeing. The study aimed to prospectively assess factors influencing the quality of life (QoL) and depression in ALS patients compared to healthy controls (HCs) from Poland, Germany and Sweden and their relationship to socio-demographic and clinical factors. METHODS: 314 ALS patients (120 from Poland, 140 from Germany, 54 from Sweden) and 311 age-, sex- and education-level-matched HCs underwent standardized interviews for quality of life, depression, functional status and pain. RESULTS: Patients from all three countries showed similar levels of functional impairment (ALSFRS-R). Overall, ALS patients assessed their quality of life as lower compared to HCs (p < 0.001 for the anamnestic comparative self-assessment (ACSA), p = 0.002 for the Schedule for the evaluation of the subjective quality of life - SEIQoL- direct weighting (SEIQoL-DW). Also, the German and Swedish patients, but not the Polish, reported higher depression levels than the corresponding HCs (p < 0.001). Analysis of ALS groups revealed that functional impairment was related to a lower quality of life (ACSA) and higher depression levels among German ALS patients. Longer time since diagnosis predicted lower depression and (in male subjects) higher quality of life. CONCLUSIONS: ALS patients assess their quality of life and mood lower than healthy individuals within the studied countries. The relationships between clinical and demographic factors are moderated by country of provenance, which bears implications for the design and interpretation of scientific and clinical studies, which should reflect the complexity and heterogeneity of mechanisms determining QoL.

Determining impairment in the Swedish, Polish and German ECAS: the importance of adjusting for age and education.

Objective: Age and years of education are strong predictors of cognitive performance in several versions of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS) and cutoffs for the Swedish and Polish versions are not established yet. Here we evaluated the performance of healthy subjects on the national versions of the Swedish and Polish ECAS and compared cognitive performance on three European translations of the ECAS. Methods: The ECAS performances of healthy subjects from Sweden (n = 111), Poland (n = 124) and Germany (n = 86) were compared. Based on the test results on the national versions of ECAS, age- and education-adjusted cutoffs were compared for the German, Swedish and Polish versions, respectively. Results: Age and years of education correlated with performance in the ECAS. Swedish subjects under the age of 60 years and Swedish subjects with low education level scored significantly higher in memory than the respective German and Polish subgroups. German and Polish subjects over 60 years of age performed significantly better in language than the respective Swedish subgroup. The Polish cohort in total had lower executive scores compared to the Swedish cohort, and lower than the German subjects in the higher education subgroup. Conclusions: The results highlight the importance of establishing age- and education-adjusted ECAS cutoffs not only in general, but also for seemingly similar populations of different origins. The results should be taken into account when comparing cognition data across patient populations including in drug trials where an ECAS test result is being used as an inclusion criterium or outcome measure.

Religiosity in patients with amyotrophic lateral sclerosis, a cross-country comparison.

PURPOSE: Amyotrophic lateral sclerosis (ALS) is a progressive motor impairment leading to early death. Religiousness is one of the factors potentially alleviating the psychological burden of patients. However, its role might vary according to cultural context. Our study aimed to analyze religiosity, and its clinical, psychological and socio-demographic correlates in ALS patients and controls, comparing two European countries with different cultural backgrounds. METHODS: 268 Polish and German ALS patients, including 18 with locked-in syndrome (LIS) and 198 healthy controls (HC) were interviewed about religiousness, quality of life (Qol), depression, functional status and pain. A follow-up was conducted on 71 patients. RESULTS: Polish subjects had a significantly higher level of public, private and general religiosity than the German sample. Importantly, we found no difference in total and public religiousness between ALS patients and HC within either population. Only the private religiousness was significantly higher in German patients compared to controls. In the same sample, private religiousness correlated with functional impairment due to disease progression. In ALS groups and LIS patients, religiousness did not correlate with any disease-associated factors: disease duration, pain, Qol or depression. Follow-up comparisons in the ALS group revealed worsening functional status, increased depression and no significant change in religiosity. CONCLUSIONS: Religiosity was linked to the cultural background rather than ALS. Generally, it did not correlate with clinical, psychological and socio-demographic parameters and was stable throughout disease progression. The only exception was the relationship between the functional decline and private religiosity among German patients.

The quality of life and depression in primary caregivers of patients with amyotrophic lateral sclerosis is affected by patient-related and culture-specific conditions.

Objective: To analyze the quality of life (QoL) and frequency of depression in primary caregivers of patients with amyotrophic lateral sclerosis (ALS) in two neighboring European countries. Methods: a cross-sectional study performed in 164 dyads of ALS patients and caregivers followed at clinical ALS centers in Poland and Germany between 2015 and 2018. The quality of life (Anamnestic Comparative Self-Assessment - ACSA, Quality of Life in Life-Threatening Illness - Family Carer Version - QOLLTI-F) and depression (ALS-Depression-Inventory 12-Items - ADI-12) of the caregivers was assessed and correlated with caregivers- and patient-related factors. Patient's clinical status was assessed by ALS Functional Rating Scale - revised and the Behavioral Score of the Edinburgh Cognitive and Behavioral ALS Screen. Results: the caregivers reported a positive QoL associated with functional and behavioral status of the patient, disease duration and caregivers's depression The most impaired domains of the QoL differed depending on the country of provenance, cultural background and/or social support of the caregivers. Depression was present in 1/3 of the caregivers and was significantly more frequent in the Polish group. It positively correlated with female gender, disease duration, sleep disturbances and functional decline. Both QoL and mood were significantly lower in the caregivers more burdened with the functional care of the patients. Conclusions: the wellbeing of caregivers of ALS patients is affected by patient-related and culture-specific conditions. Understanding the needs and background of psychological adaptation of the caregivers from various countries may translate into better QoL and local patient care.

Attitudes of caregivers towards prolonging and shortening life in advanced stages of amyotrophic lateral sclerosis.

INTRODUCTION: Inevitable disease progression in amyotrophic lateral sclerosis (ALS) forces patients and their caregivers (CGs) to reflect on end-of-life treatment. The CGs are often heavily burdened with their role of surrogate decision-makers. The aim of the study was to analyze attitudes of CGs and presumable attitudes of ALS patients from the CGs' perspective towards palliative care in advanced disease stages. MATERIAL AND METHODS: One hundred and sixty four CGs from Germany and Poland were interviewed regarding their own preferences and patients' ideational attitudes towards life-prolonging (invasive and non-invasive ventilation, tube feeding) and life-shortening methods (termination of measures, active measures if permitted by law). The data were correlated with patient- and CG-related factors: demographic and clinical data, care commitment, depression and quality of life (QoL). RESULTS: The CGs were mostly female spouses of ALS patients, with secondary/higher education. Nearly 70% (81% in Poland, 57% in Germany; p = 0.0001) reported positive attitudes towards life-prolonging methods, which positively correlated with religiousness and negatively with patients' age. Approximately 40% of CGs (25% and 51% respectively; p = 0.001) reported positive attitudes towards life-shortening methods. It positively correlated with time since diagnosis and negatively with the CG's QoL, religiosity and religious/spiritual faith as factors that significantly influenced end-of-life decisions. There was a strongly positive correlation between CGs' positive attitudes towards life-shortening methods and presumed positive patients' attitudes assessed by their CGs ( p < 0.000001). CONCLUSIONS: Although attitudes towards treatment differed between countries, the CGs of ALS patients were generally positive towards life-prolonging treatment. A greater acceptance of life-shortening methods in the case of longer disease duration and poorer QoL may indicate worse coping with disease progression and weaker adaptation mechanisms in CGs compared to those previously reported in ALS patients. A close resemblance of the CGs' answers to probable patients' attitudes reported by the CGs indicates that many GCs might actually express their own culturally shaped attitudes towards end-of-life methods. In light of earlier-reported discrepancies between presumed opinions of the CGs and of patients themselves, a greater focus should be placed on thorough discussions on future treatment options with ALS patients in the presence of their CGs, to stay in line with the patient's authentic will.

Caregivers' divergent perspectives on patients' well-being and attitudes towards hastened death in Germany, Poland and Sweden.

Background: During the course of amyotrophic lateral sclerosis (ALS), patients and their families are faced with existential decisions concerning life-prolonging and -shortening measures. Correct anticipation of patient's well-being and preferences is a prerequisite for patient-centered surrogate decision making. Methods: In Germany (N = 84), Poland (N = 77) and Sweden (N = 73) patient-caregiver dyads were interviewed. Standardized questionnaires on well-being (ADI-12 for depressiveness; ACSA for global quality of life) and wish for hastened death (SAHD) were used in ALS patients. Additionally, caregivers were asked to fill out the same questionnaires by anticipating patients' perspective (surrogate perspective). Results: Caregivers significantly underestimated patients' well-being in Germany and Poland. For Swedish caregivers, there were just as many who underestimated and overestimated well-being. The same was true for wish for hastened death in all three countries. For Swedish and Polish patients, caregivers' estimation of well-being was not even associated with patients' responses and the same was true for estimation of wish for hastened death in all three countries. Older caregivers and those with the most frequent encounter with the patient were the closest in their rating of well-being and wish for hastened death to the patients' actual state, while caregivers with chronic disease him/herself were more likely to underestimate patient's well-being. Discussion: Despite distinct cultural differences, there was a clear discrepancy between patients' and caregivers' perspective on patients' well-being and preferences towards life in all three countries. This possible bias in caregivers' judgment needs to be taken into account in surrogate decision making.

Healthcare provision in amyotrophic lateral sclerosis: procedures, queries and pitfalls in Germany and Poland.

There are a number of physical restrictions that develop in the course of amyotrophic lateral sclerosis (ALS). While loss of speech and motor control may be partially compensated by the support of assistive devices, swallowing difficulty and respiratory insufficiency require medical interventions (percutaneous endoscopic gastrostomy, noninvasive, and invasive ventilation). Based on the data collected within the NEEDSinALS study, we found major differences in personal satisfaction with the financing, healthcare provision, medical infrastructure, and regulations of German and Polish ALS patients, despite minor differences in economic burden caused by the disease. In order to explain this phenomenon, we thoroughly reviewed the legal basis, structure and organization of the healthcare systems in Germany and Poland to determine the range of obstacles in the everyday lives of patients and their caregivers that are attempting to attain an assistive device or care after the start of medical interventions.

An observational study on quality of life and preferences to sustain life in locked-in state.

OBJECTIVE: This is an observational study on well-being and end-of-life preferences in patients with amyotrophic lateral sclerosis (ALS) in the locked-in state (LIS) in a Polish sample within the EU Joint Programme-Neurodegenerative Disease Research study NEEDSinALS (NEEDSinALS.com). METHODS: In this cross-sectional study, patients with ALS in LIS (n = 19) were interviewed on well-being (quality of life, depression) as a measure of psychosocial adaptation, coping mechanisms, and preferences towards life-sustaining treatments (ventilation, percutaneous endoscopic gastroscopy) and hastened death. Also, clinical data were recorded (ALS Functional Rating Scale-revised version). Standardized questionnaires (Anamnestic Comparative Self-Assessment [ACSA], Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), ALS Depression Inventory-12 items [ADI-12], schedule of attitudes toward hastened death [SAHD], Motor Neuron Disease Coping Scale) were used, which were digitally transcribed; answers were provided via eye-tracking control. In addition, caregivers were asked to judge patients' well-being. RESULTS: The majority of patients had an ACSA score >0 and a SEIQoL score >50% (indicating positive quality of life) and ADI-12 <29 (indicating no clinically relevant depression). Physical function did not reflect subjective well-being; even more, those with no residual physical function had a positive well-being. All patients would again choose the life-sustaining techniques they currently used and their wish for hastened death was low (SAHD <10). Caregivers significantly underestimated patient's well-being. INTERPRETATION: Some patients with ALS in LIS maintain a high sense of well-being despite severe physical restrictions. They are content with their life-sustaining treatments and have a strong will to live, which both may be underestimated by their families and public opinion.

Therapeutic decisions in ALS patients: cross-cultural differences and clinical implications.

OBJECTIVE: Quantitative analysis of decision-making on therapeutic options in different sociocultural context in amyotrophic lateral sclerosis (ALS). METHODS: ALS patients (n = 244) were consecutively recruited in Germany (n = 83), Poland (n = 83), and Sweden (n = 78) in a prospective cross-cultural study ( www.NEEDSinALS.com ). They were interviewed on preferences for therapeutic techniques including invasive (IV) and non-invasive ventilation (NIV), as well as percutaneous endoscopic gastrostomy (PEG) and on hypothetical termination of these using quantitative questions. Using standardized questionnaires, religiousness, personal values, quality of life, and depressiveness were assessed. RESULTS: NIV was most frequently used in Germany and PEG in Sweden. Swedish patients were most liberal on initiation and termination of PEG, NIV and IV. Polish patients were mostly undecided and were least likely to consider discontinuing supportive management. Current use was partly associated with age, gender and state of physical function; also, financial support explained some variance. Future preferences on therapeutic options from the patient's perspective were also closely associated with cultural factors. The more oriented towards traditional and conservative values, the less likely patients were to decide for invasive therapeutic devices (IV, PEG), the least likely to have ideations to discontinue any device and the more likely to have an undecided attitude. CONCLUSIONS: Current use of therapeutic options is determined by medical condition in analogy to clinical guidelines. For future considerations, other factors such as cultural background are crucial, yielding hurdles to be regarded in the implementation of advanced directives in a multicultural environment.

Existential decision-making in a fatal progressive disease: how much do legal and medical frameworks matter?

BACKGROUND: Healthcare legislation in European countries is similar in many respects. Most importantly, the framework of informed consent determines that physicians have the duty to provide detailed information about available therapeutic options and that patients have the right to refuse measures that contradict their personal values. However, when it comes to end-of-life decision-making a number of differences exist in the more specific regulations of individual countries. These differences and how they might nevertheless impact patient's choices will be addressed in the current debate. MAIN TEXT: In this article we show how the legal and medical frameworks of Germany, Poland and Sweden differ with regard to end-of-life decisions for patients with a fatal progressive disease. Taking Amyotrophic Lateral Sclerosis (ALS) as an example, we systematically compare clinical guidelines and healthcare law, pointing out the country-specific differences most relevant for existential decision-making. A fictional case report discusses the implications of these differences for a patient with ALS living in either of the three countries. Patients with ALS in Germany, Poland and Sweden are confronted with a similar spectrum of treatment options. However, the analysis of the normative frameworks shows that the conditions for making existential decisions differ considerably in Germany, Poland and Sweden. Specifically, these differences concern (1) the legal status of advance directives, (2) the conditions under which life-sustaining therapies are started or withheld, and (3) the legal regulations on assisted dying. CONCLUSION: According to the presented data, regulations of terminating life-sustaining treatments and the framework of "informed consent" are quite differently understood and implemented in the legal setting of the three countries. It is possible, and even likely, that these differences in the legal and medical frameworks have a considerable influence on existential decisions of patients with ALS.
