Semiotics of ICU Physicians' Views on End-of-life Care and Quality of Dying in a Critical Care Setting: A Qualitative Study

Background and aim

While intensive care unit (ICU) mortality rates in India are higher when compared to countries with more resources, fewer patients with clinically futile conditions are subjected to limitation of life-sustaining treatments or given access to palliative care. Although a few surveys and audits have been conducted exploring this phenomenon, the qualitative perspectives of ICU physicians regarding end-of-life care (EOLC) and the quality of dying are yet to be explored.

Methods

There are 22 eligible consultant-level ICU physicians working in multidisciplinary ICUs were purposively recruited and interviewed. The study data was analyzed using reflexive thematic analysis (RTA) with a critical realist perspective, and the study findings were interpreted using the lens of the semiotic theory that facilitated the development of themes.

Results

About four themes were generated. Intensive care unit physicians perceived the quality of dying as respecting patients' and families' choices, fulfilling their needs, providing continued care beyond death, and ensuring family satisfaction. To achieve this, the EOLC process must encompass timely decision-making, communication, treatment guidelines, visitation rights, and trust-building. The contextual challenges were legal concerns, decision-making complexities, cost-related issues, and managing expectations. To improve care, ICU physicians suggested amplifying patient and family voices, building therapeutic relationships, mitigating conflicts, enhancing palliative care services, and training ICU providers in EOLC.

Conclusion

Effective management of critically ill patients with life-limiting illnesses in ICUs requires a holistic approach that considers the complex interplay between the EOLC process, its desired outcome, the quality of dying, care context, and the process of meaning-making by ICU physicians.

Which has more influence on a family's assessment of the quality of dying of their long-term care resident with dementia: Frequency of symptoms or quality of communication with healthcare team?

OBJECTIVE

Symptoms present at the end of life and the quality of communication with the healthcare team have both been shown to impact family assessments of the quality of dying of their loved one with dementia. However, the relative contributions of these two factors to family assessments have not yet been investigated. To address this knowledge gap, we explored which of these two factors has more influence on family assessments of the quality of dying of long-term care (LTC) residents with dementia.

METHOD

This is a secondary analysis of a mortality follow-back study. Ninety-four family members of LTC residents who had died with dementia assessed the quality of dying (very good or not very good), the frequency of symptoms, and the quality of communication with the healthcare team using a self-administered questionnaire mailed 1 month after the resident's death. Logistic regression analyses were performed to determine the relative contributions of the two independent variables of primary interest (frequency of symptoms and quality of communication) to the families' assessments of the quality of dying.

RESULTS

Multivariate analyses revealed that the quality of communication with the healthcare team was closely linked to the quality of dying (p = 0.009, OR = 1.34, 95% CI = 1.09-1.65), whereas the frequency of symptoms was not (p = 0.142, OR = 1.05, 95% CI = 0.98-1.11) after controlling for potential confounders.

SIGNIFICANCE OF RESULTS

Our findings show that healthcare providers' ability to engage in the end-of-life conversations with families outweighs the frequency of symptoms in family assessments of the quality of dying of their relative with dementia. Enhancing healthcare providers' ability to communicate with families about the end-of-life care could improve families' perceptions of the quality of dying of their relative with dementia and, consequently, ease their grieving process.

To hydrate or not to hydrate? The effect of hydration on survival, symptoms and quality of dying among terminally ill cancer patients

Background

Artificial nutrition and hydration do not prolong survival or improve clinical symptoms of terminally ill cancer patients. Nonetheless, little is known about the effect of artificial hydration (AH) alone on patients’ survival, symptoms or quality of dying. This study explored the relationship between AH and survival, symptoms and quality of dying among terminally ill cancer patients.

Methods

A pilot prospective, observational study was conducted in the palliative care units of three tertiary hospitals in Taiwan between October 2016 and December 2017. A total of 100 patients were included and classified into the hydration and non-hydration group using 400 mL of fluid per day as the cut-off point. The quality of dying was measured by the Good Death Scale (GDS). Multivariate analyses using Cox’s proportional hazards model were used to assess the survival status of patients, the Wilcoxon rank-sum test for within-group analyses and the Mann-Whitney U test for between-groups analyses to evaluate changes in symptoms between day 0 and 7 in both groups. Logistic regression analysis was used to assess the predictors of a good death.

Results

There were no differences in survival (p = 0.337) or symptom improvement between the hydration and non-hydration group, however, patients with AH had higher GDS scores.

Conclusions

AH did not prolong survival nor significantly improve dehydration symptoms of terminally ill cancer patients but it may influence the quality of dying. Communication with patients and their families on the effect of AH may help them better prepared for the end-of-life experience.

Association of sleep duration with risk of all-cause mortality and poor quality of dying in oldest-old people: a community-based longitudinal study

Background

While sleep duration has been shown to be associated with health outcomes, few studies have been conducted among the oldest old. In addition, the impact of sleep duration on quality of dying is unknown. We aimed to evaluate how sleep duration affects all-cause mortality and quality of dying in people aged 80 + .

Methods

This community-based longitudinal study was performed by using data from 15,048 individuals aged ≥80 with information on sleep duration in the Chinese Longitudinal Healthy Longevity Survey. Cox and logistic regression models with penalized splines were applied to explore the shape of the association between sleep duration and all-cause mortality and poor quality of dying respectively and identify the interval of sleep duration resulting in the lowest risk of both.

Results

During a median follow-up of 3.1 years, 11,582 deaths including 4116 individuals who experienced poor quality of dying were recorded. Sleep duration showed a U-shaped association with all-cause mortality and sleeping about 8 h had the minimum risk of death; a J-shaped association was found between sleep duration and poor quality of dying. Compared with sleep duration of 7–9 h, the adjusted hazard ratio of total deaths was 1.08 (95% CI 1.03–1.13) for short duration (< 7 h) and 1.12 (95% CI 1.07–1.17) for long duration (> 9 h); the adjusted odds ratio of poor QOD was 1.10 (95% CI 1.01–1.21) for long duration, but this association was restricted to those with baseline unhealthy status (P-interaction = 0.04).

Conclusions

Sleeping a little longer may be better for individuals over 80 years old, and sleep duration of 7–9 h per day is optimal for both survival and good quality of life near death.

Quality of dying and death desired by residents of Kagawa Prefecture, Japan: a qualitative study

Background

Achieving a desirable death is an urgent aging-related problem in Japan. However, measures of the quality of death and dying in Japan are lacking. This study aimed to identify components of a desirable death in the residents of Kagawa prefecture, Japan, through focus group interviews.

Methods

A group interview was conducted with 30 residents aged 20–80 (M_age = 50.9, SD = 22.1 years; 43.3% ≥ 65 years; 40.0% unemployed) who had experienced the death of a closely associated person. Participants were grouped into four generations with diverse characteristics (e.g., age, sex, occupation). The interview lasted 1–2 h and involved one interviewer, one observer, and one recorder. The interview theme was “What is a desirable death?” Participants were asked “What do you want to achieve before you die?” or “What would a close friend want to experience when death is near?” We then extracted important items related to “desirable death” using serialization and observation records, while also consulting three analysts. The analysis results of the four generations were ultimately integrated into final categories.

Results

The most common experience of a familiar death was that of parents, followed by grandparents. Half of participants had witnessed the death. Through category analysis, eight important categories related to desirable death were ultimately extracted. Nine items were identified as common to all generations. While the elderly generation had wide-ranging opinions, the younger generations’ opinions tended to concentrate on satisfaction with life and family relations.

Conclusion

Eight concepts were extracted as important factors of a desirable death from the residents of Kagawa prefecture, Japan.

End of life care for long-term care residents with dementia, chronic illness and cancer: prospective staff survey

Background

Little is known about the quality of end of life care in long-term care (LTC) for residents with different diagnostic trajectories. The aim of this study was to compare symptoms before death in LTC for those with cancer, dementia or chronic illness.

Methods

After-death prospective staff survey of resident deaths with random cluster sampling in 61 representative LTC facilities across New Zealand (3709 beds). Deaths (n = 286) were studied over 3 months in each facility. Standardised questionnaires - Symptom Management (SM-EOLD) and Comfort Assessment in End of life with Dementia (CAD-EOLD) - were administered to staff after the resident’s death.

Results

Primary diagnoses at the time of death were dementia (49%), chronic illness (30%), cancer (17%), and dementia and cancer (4%). Residents with cancer had more community hospice involvement (30%) than those with chronic illness (12%) or dementia (5%). There was no difference in mean SM-EOLD in the last month of life by diagnosis (cancer 26.9 (8.6), dementia 26.5(8.2), chronic illness 26.9(8.6). Planned contrast analyses of individual items found people with dementia had more pain and those with cancer had less anxiety. There was no difference in mean CAD-EOLD scores in the week before death by diagnosis (total sample 33.7(SD 5.2), dementia 34.4(SD 5.2), chronic illness 33.0(SD 5.1), cancer 33.3(5.1)). Planned contrast analyses showed significantly more physical symptoms for those with dementia and chronic illness in the last month of life than those with cancer.

Conclusions

Overall, symptoms in the last week and month of life did not vary by diagnosis. However, sub-group planned contrast analyses found those with dementia and chronic illness experienced more physical distress during the last weeks and months of life than those with cancer. These results highlight the complex nature of LTC end of life care that requires an integrated gerontology/palliative care approach.

Quality of dying and death in the ICU. The euroQ2 project

PURPOSE

Knowledge of families' perspective of quality of intensive care unit (ICU) care is important, especially with regard to end-of-life (EOL) care. Adaptation of the US-developed "Quality of dying and death questionnaire" (QODD) to a European setting is lacking. The primary aim of this study is to examine the euroQODD's usability and its assessments of EOL care in a cohort of Danish and Dutch family members.

METHODS

Family members of patients dying in an ICU after a stay of at least 48h were sent the euroQODD three weeks after the patient died. Selected patient characteristics were obtained from hospital records. A total of 11 Danish and 10 Dutch ICU's participated.

RESULTS

217 family members completed the euroQODD part of the euroQ2 questionnaire. Overall rating of care was high, a median of 9 in Netherlands and 10 in Denmark on a 0-10 scale (p<0.001). The Danish were more likely to report adequate pain control all or most of the time (95% vs 73%; p<0.001). When decisions were made to limit treatment, the majority of family members agreed (93%). Most (92%) reported some participation in the decision-making, with half (50%) making the decision jointly with the doctor. About 18% would have preferred greater involvement. Factor analysis identified a six-indicator unidimensional quality of dying and death construct with between-country measurement invariance. However, in its current form the euroQODD instrument requires modeling the six items as reflective (or effect) indicators, when they are more accurately conceived as causal indicators.

CONCLUSIONS

The majority of family members were satisfied with the quality of EOL care and quality of dying and death. They agreed with decisions made to limit treatment and most felt they had participated to some extent in decision-making, although some would have preferred greater participation. Addition of items that can be accurately treated as effect indicators will improve the instrument's usefulness in measuring the overall quality of dying and death.

End-of-Life Care and Quality of Dying in 23 Acute Geriatric Hospital Wards in Flanders, Belgium

OBJECTIVES

To describe the nursing and medical interventions performed in the last 48 hours of life and the quality of dying of patients dying in acute geriatric hospital wards.

METHODS

Cross-sectional descriptive study between October 1, 2012 and September 30, 2013. Twenty-three acute geriatric wards in 13 hospitals in Flanders, Belgium. Patients hospitalized for more than 48 hours before dying in the participating wards. Structured after-death questionnaires, filled out by the nurse, the physician, and the family carer most involved in end-of-life care. Main outcome measures were several nursing and medical interventions reported to be performed in the last 48 hours of life and the quality of dying.

RESULTS

Of 993 patients, we included 338 (mean age 85.7 years; 173 women). Almost 58% had dementia and nearly half were unable to communicate in the last 48 hours of their life. The most frequently continued or started nursing and medical interventions in the last 48 hours of life were measuring temperature (91.6%), repositioning (83.3%), washing (89.5%), oxygen therapy (49.7%), and intravenous fluids and nutrition (30%). Shortness of breath, lack of serenity, lack of peace, and lack of calm were symptoms reported most frequently by nurses and family carers.

CONCLUSION

Many nursing and medical interventions are continued or started in the last hours of a patient's life, which may not always be in their best interests. Furthermore, patients dying in acute geriatric wards are often affected by several symptoms.
