A validated risk score to estimate mortality risk in patients with dementia and pneumonia: barriers to clinical impact

Influence of research evidence on the use of cardiovascular clinical prediction rules in primary care: an exploratory qualitative interview study

BACKGROUND

Cardiovascular clinical prediction rules (CPRs) are widely used in primary care. They accumulate research evidence through derivation, external validation, and impact studies. However, existing knowledge about the influence of research evidence on the use of CPRs is limited. Therefore, we explored how primary care clinicians' perceptions of and experiences with research influence their use of cardiovascular CPRs.

METHODS

We conducted an exploratory qualitative interview study with thematic analysis. Primary care clinicians were recruited from the WWAMI (Washington, Wyoming, Alaska, Montana and Idaho) region Practice and Research Network (WPRN). We used purposeful sampling to ensure maximum variation within the participant group. Data were collected by conducting semi-structured online interviews. We analyzed data using inductive thematic analysis to identify commonalities and differences within themes.

RESULTS

Of 29 primary care clinicians who completed the questionnaire, 15 participated in the interview. We identified two main themes relating to the influence of clinicians' perceptions of and experiences with cardiovascular CPR research on their decisions about using cardiovascular CPRs: "Seek and judge" and "be acquainted and assume." When clinicians are familiar with, trust, and feel confident in using research evidence, they might actively search and assess the evidence, which may then influence their decisions about using cardiovascular CPRs. However, clinicians, who are unfamiliar with, distrust, or find it challenging to use research evidence, might be passively acquainted with evidence but do not make their own judgment on the trustworthiness of such evidence. Therefore, these clinicians might not rely on research evidence when making decisions about using cardiovascular CPRs.

CONCLUSIONS

Clinicians' perceptions and experiences could influence how they use research evidence in decisions about using cardiovascular CPRs. This implies, when promoting evidence-based decisions, it might be useful to target clinicians' unfamiliarity, distrust, and challenges regarding the use of research evidence rather than focusing only on their knowledge and skills. Further, because clinicians often rely on evidence-unrelated factors, guideline developers and policymakers should recommend cardiovascular CPRs supported by high-quality evidence.

Triggering palliative care referrals through the identification of poor prognosis in older patients presented to emergency departments in rural Australia

Background: Without objective screening for risk of death, the palliative care needs of older patients near the end of life may be unrecognised and unmet. Aim: This study aimed to estimate the usefulness of the Criteria for Screening and Triaging to Appropriate aLternative care (CriSTAL) tool in determining older patients' risk of death within 3-months after initial hospital admission. Methods: A prospective cohort study of 235 patients aged 70+ years, who presented to two rural emergency departments in two adjacent Australian states, was utilised. The 'risk of death' of each patient was screened with the CriSTAL prognostic tool. Their 3-month follow-up outcomes were assessed through telephone interviews and a clinical record review. Findings: A CriSTAL cut-off score of more than 7 yielded a sensitivity of 80.7% and specificity of 70.81% for a 3-month risk of death. Palliative care services were only used by 31% of the deceased in their last trimester of life. Conclusion: Prognostic tools provide a viable means of identifying individuals with a poor prognosis. Identification can trigger an earlier referral to palliative care, which will benefit the patient's wellbeing and quality of life.

Palliative care for people with dementia

Dementia is the most common neurologic disease, affecting approximately 55 million people worldwide. Dementia is a terminal illness, although not always recognized as such. This chapter discusses the key issues in providing palliative care for people with living with dementia and their families. Common palliative care needs and symptoms are presented, including psychosocial, physical, emotional, and spiritual, and the need to actively anticipate and seek symptoms according to the dementia type and stage is emphasized. Families are hugely impacted by a dementia diagnosis, and throughout this chapter, they are considered in the unit of care, and also as a member of the care team. Multiple challenges particular to dementia palliative care are highlighted throughout, such as the lack of timely dementia diagnoses, difficulty with symptom prognostication, the person's inability to verbally express their symptoms and care preferences, and a low threshold for medication side effects. Finally, service models for dementia palliative care in community, residential, and acute hospital settings are discussed, along with the evidence for each. Overall, this chapter reinforces that the individual needs of the person living with dementia and their family must be considered to provide person-centered and comprehensive palliative care, enabling them to live well until death.

Family Caregiver's Depression, Confidence, Satisfaction, and Burden Regarding End-of-Life Home Care for People With End-Stage Dementia

To detect differences between two care services units: regarding family-caregiver (FC) depression, perceived-burden and confidence in the provision of care to people with end-stage dementia (PWESD); examine predictors such as FC age, depression, confidence in the provision of care to PWESD and satisfaction with the community-home-care service to burden; and explore a mediation model.The participants were 139 FC, caring for PWESD living at home. The questionnaire was composed of FC background characteristics, perceived-burden, satisfaction with the community-home-care services, depression, and confidence in the provision of care to the PWESD. HCUs' FC felt significantly more burdened than HHUs' FC. Furthermore, satisfaction with the community-home-care services mediated the relationship between FC confidence in the provision of care to the PWESD and FC burden. The study results may affect the development of end-of-life care policies and services which meet the needs of PWESD and their FC.

Emotion work and feeling rules: Coping strategies of family caregivers of people with end stage dementia in Israel-A qualitative study

Background

End stage dementia is an inevitable phase following a prolonged deterioration. Family caregivers for people with end stage dementia who live in their home can experience an emotional burden. Emotion work and “feeling-rules” refers to socially shared norms and self-management of feelings, as well as projecting emotions appropriate for the situation, aiming at achieving a positive environment as a resource for supporting others’ wellbeing.

Objectives

Exploring and describing the experience of family caregivers of people with end stage dementia at home, in Israel, unpacking their emotional coping and the emotional-strategies they use, and placing family caregivers' emotion work in a cultural context.

Method

We conducted fifty qualitative interviews using semi structured interviews analyzed through a thematic content analysis approach.

Findings

Four characteristics of emotion work were identified: (1) sliding between detachment and engagement, (2) separating the person from their condition (3), adoption of caregiving as a social role and a type of social reinforcement, and (4) using the caregiving role in coping with loneliness and emptiness. The emotional coping strategies are culturally contextualized, since they are influenced by the participants’ cultural background.

Discussion

This article’s focus is transparent family caregivers' emotion work, a topic which has rarely been discussed in the literature is the context of caring for a family member with dementia at home. In our study, emotion work appears as a twofold concept: the emotion work by itself contributed to the burden, since family caregivers' burden experience can evolve from the dissonance between their “true” feelings of anger and frustration and their expected “acceptable” feelings (“feeling-rules”) formed by cultural norms. However, emotion work was also a major source of coping and finding strength and self-meaning. Understanding and recognizing the emotion work and the cultural and religious influence in this coping mechanism can help professionals who treat people with end stage dementia to better support family-caregivers.

Discussing Personalized Prognosis Empowers Patients with Amyotrophic Lateral Sclerosis to Regain Control over Their Future: A Qualitative Study

The ENCALS survival prediction model offers patients with amyotrophic lateral sclerosis (ALS) the opportunity to receive a personalized prognosis of survival at the time of diagnosis. We explored experiences of patients with ALS, caregivers, and physicians with discussing personalized prognosis through interviews with patients and their caregivers, and in a focus group of physicians. Thematic analysis revealed four themes with seven subthemes; these were recognized by the focus group. First, tailored communication: physician’s communication style and information provision mediated emotional impact and increased satisfaction with communication. Second, personal factors: coping style, illness experiences, and information needs affected patient and caregiver coping with the prognosis. Third, emotional impact ranged from happy and reassuring to regret. Fourth, regaining control over the future: participants found it helpful in looking towards the future, and emphasized the importance of quality over quantity of life. Personalized prognosis can be discussed with minimal adverse emotional impact. How it is communicated—i.e., tailored to individual needs—is as important as what is communicated—i.e., a good or poor prognosis. Discussing personalized prognosis may help patients with ALS and their caregivers regain control over the future and facilitate planning of the future (care). For many patients, quality of life matters more than quantity of time remaining.

Ethical challenges in end-stage dementia: Perspectives of professionals and family care-givers

BACKGROUND

In Israel, caring for people with end-stage dementia confined to home is mainly done by home care units, and in some cases by home hospice units, an alternative palliative-care service. Because life expectancy is relatively unknown, and the patient's decision-making ability is poor, caring for this unique population raises ethical dilemmas regarding when to define the disease as having reached a terminal stage, as well as choosing between palliative and life-prolonging-oriented care.

OBJECTIVES

Exploring and describing differences and similarities of professional staff members' (PSMs') and family caregivers' perceptions of caring for people with end-stage dementia in two different settings.

DESIGN

Qualitative research, using semi-structured interviews analyzed through a thematic content-analysis approach.

PARTICIPANTS

Sixty-four interviews were conducted (24 PSMs and 40 family caregivers) in two care-settings-home hospice unit and home care unit.

ETHICAL CONSIDERATIONS

The study was approved by the Ethics Committee (BBL00118-17).

FINDINGS

We found dilemmas regarding palliative care to be the main theme, including definition of the disease as terminal, choosing "comfort" over "life-prolonging," clarifying patients' wishes and deciding whether or not to use artificial feeding.

DISCUSSION

Both PSMs and family caregivers deal with ethical dilemmas and have reached different conclusions, both legitimate. Comprehending dementia as a terminal disease influenced participants' perceptions of the relevancy of palliative care for people with end-stage dementia. Discrepancies between PSMs and family caregivers in caring for people with end-stage dementia were found in both home hospice unit and home care unit environments, raising potential conflicts regarding decisions for end-of-life care.

CONCLUSIONS

Communication between PSMs and family caregivers is crucial for the discussion about the discrepancies regarding the unique dilemmas of caring for people with end-stage dementia and bridging the gap between them. Lack of communication and resources can hamper the provision of an acceptable solution for quality and equality of care in the best interest of people with end-stage dementia.

Discussing personalized prognosis in amyotrophic lateral sclerosis: development of a communication guide

BACKGROUND

Personalized ENCALS survival prediction model reliably estimates the personalized prognosis of patients with amyotrophic lateral sclerosis. Concerns were raised on discussing personalized prognosis without causing anxiety and destroying hope. Tailoring communication to patient readiness and patient needs mediates the impact of prognostic disclosure. We developed a communication guide to support physicians in discussing personalized prognosis tailored to individual needs and preferences of people with ALS and their families.

METHODS

A multidisciplinary working group of neurologists, rehabilitation physicians, and healthcare researchers A) identified relevant topics for guidance, B) conducted a systematic review on needs of patients regarding prognostic discussion in life-limiting disease, C) drafted recommendations based on evidence and expert opinion, and refined and finalized these recommendations in consensus rounds, based on feedback of an expert advisory panel (patients, family member, ethicist, and spiritual counsellor).

RESULTS

A) Topics identified for guidance were 1) filling in the ENCALS survival model, and interpreting outcomes and uncertainty, and 2) tailoring discussion to individual needs and preferences of patients (information needs, role and needs of family, severe cognitive impairment or frontotemporal dementia, and non-western patients). B) 17 studies were included in the systematic review. C) Consensus procedures on drafted recommendations focused on selection of outcomes, uncertainty about estimated survival, culturally sensitive communication, and lack of decisional capacity. Recommendations for discussing the prognosis include the following: discuss prognosis based on the prognostic groups and their median survival, or, if more precise information is desired, on the interquartile range of the survival probability. Investigate needs and preferences of the patients and their families for prognostic disclosure, regardless of cultural background. If the patient does not want to know their prognosis, with patient permission discuss the prognosis with their family. If the patient is judged to lack decisional capacity, ask the family if they want to discuss the prognosis. Tailor prognostic disclosure step by step, discuss it in terms of time range, and emphasize uncertainty of individual survival time.

CONCLUSION

This communication guide supports physicians in tailoring discussion of personalized prognosis to the individual needs and preferences of people with ALS and their families.

Antimicrobial use at the end of life: a scoping review

OBJECTIVE

To examine antibiotic use in patients approaching end of life, in terms of frequency of prescription, aim of treatment, beneficial and adverse effects and contribution to the development of antimicrobial resistance.

DESIGN

Scoping review DATA SOURCES: An information scientist searched Ovid MEDLINE, Ovid EMBASE, The Cochrane library, PubMed Clinical Queries, NHS Evidence, Epistemonikos, SIGN, NICE, Google Scholar from inception to February 2019 for any study design including, but not limited to, randomised clinical trials, prospective interventional or observational studies, retrospective studies and qualitative studies. The search of Ovid MEDLINE was updated on the 10 June 2020.

STUDY SELECTION

Studies reporting antibiotic use in patients approaching end of life in any setting and clinicians' attitudes and behaviour in relation to antibiotic prescribing in this population DATA EXTRACTION: Two reviewers screened studies for eligibility; two reviewers extracted data from included studies. Data were analysed to describe antibiotic prescribing patterns across different patient populations, the benefits and adverse effects (for individual patients and wider society), the rationale for decision making and clinicians behaviours and attitudes to treatment with antibiotics in this patient group.

RESULTS

Eighty-eight studies were included. Definition of the end of life is highly variable as is use of antibiotics in patients approaching end of life. Prescribing decisions are influenced by patient age, primary diagnosis, care setting and therapy goals, although patients' preferences are not always documented or adhered to. Urinary and lower respiratory tract infections are the most commonly reported indications with outcomes in terms of symptom control and survival variably reported. Small numbers of studies reported on adverse events and antimicrobial resistance. Clinicians sometimes feel uncomfortable discussing antibiotic treatment at end of life and would benefit from guidelines to direct care.

CONCLUSIONS

Use of antibiotics in patients approaching the end of life is common although there is significant variation in practice. There are a myriad of intertwined biological, ethical, social, medicolegal and clinical issues associated with the topic.

Components of palliative care interventions addressing the needs of people with dementia living in long-term care: A systematic review

BACKGROUND

People with dementia requiring palliative care have multiple needs, which are amplified in long-term care settings. The European Association for Palliative Care White Paper offers recommendations for optimal palliative care in dementia integral for this population, providing useful guidance to inform interventions addressing their specific needs.

AIM

The aim of this study is to describe the components of palliative care interventions for people with dementia in long-term care focusing on shared decision-making and examine their alignment to the European Association for Palliative Care domains of care.

DESIGN

Systematic review with narrative synthesis (PROSPERO ID: CRD42018095649).

DATA SOURCES

Four databases (MEDLINE, CINAHL, PsycINFO and CENTRAL) were searched (earliest records - July 2019) for peer-reviewed articles and protocols in English, reporting on palliative care interventions for people with dementia in long-term care, addressing European Association for Palliative Care Domains 2 (person-centred) or 3 (setting care goals) and ⩾1 other domain.

RESULTS

Fifty-one papers were included, reporting on 32 studies. For each domain (1-10), there were interventions found aiming to address its goal, although no single intervention addressed all domains. Domain 7 (symptom management; n = 19), 6 (avoiding overly aggressive treatment; n = 18) and 10 (education; n = 17) were the most commonly addressed; Domain 5 (prognostication; n = 7) and 4 (continuity of care; n = 2) were the least addressed.

CONCLUSION

Almost all domains were addressed across all interventions currently offered for this population to various degrees, but not within a singular intervention. Future research optimally needs to be theory driven when developing dementia-specific interventions at the end of life, with the European Association for Palliative Care domains serving as a foundation to inform the best care for this population.

Survival time tool to guide care planning in people with dementia

OBJECTIVE

To develop survival prediction tables to inform physicians and patients about survival probabilities after the diagnosis of dementia and to determine whether survival after dementia diagnosis can be predicted with good accuracy.

METHODS

We conducted a nationwide registry-linkage study including 829 health centers, i.e., all memory clinics and ≈75% of primary care facilities, across Sweden. Data including cognitive function from 50,076 people with incident dementia diagnoses ≥65 years of age and registered with the Swedish Dementia Register in 2007 to 2015 were used, with a maximum follow-up of 9.7 years for survival until 2016. Sociodemographic factors, comorbidity burden, medication use, and dates of death were obtained from nationwide registries. Cox proportional hazards regression models were used to create tables depicting 3-year survival probabilities for different risk factor profiles.

RESULTS

By August 2016, 20,828 (41.6%) patients in our cohort had died. Median survival time from diagnosis of dementia was 5.1 (interquartile range 2.9-8.0) years for women and 4.3 (interquartile range 2.3-7.0) years for men. Predictors of mortality were higher age, male sex, increased comorbidity burden and lower cognitive function at diagnosis, a diagnosis of non-Alzheimer dementia, living alone, and using more medications. The developed prediction tables yielded c indexes of 0.70 (95% confidence interval [CI] 0.69-0.71) to 0.72 (95% CI 0.71-0.73) and showed good calibration.

CONCLUSIONS

Three-year survival after dementia diagnosis can be predicted with good accuracy. The survival prediction tables developed in this study may aid clinicians and patients in shared decision-making and advance care planning.

Methodological standards for the development and evaluation of clinical prediction rules: a review of the literature

Clinical prediction rules (CPRs) that predict the absolute risk of a clinical condition or future outcome for individual patients are abundant in the medical literature; however, systematic reviews have demonstrated shortcomings in the methodological quality and reporting of prediction studies. To maximise the potential and clinical usefulness of CPRs, they must be rigorously developed and validated, and their impact on clinical practice and patient outcomes must be evaluated. This review aims to present a comprehensive overview of the stages involved in the development, validation and evaluation of CPRs, and to describe in detail the methodological standards required at each stage, illustrated with examples where appropriate. Important features of the study design, statistical analysis, modelling strategy, data collection, performance assessment, CPR presentation and reporting are discussed, in addition to other, often overlooked aspects such as the acceptability, cost-effectiveness and longer-term implementation of CPRs, and their comparison with clinical judgement. Although the development and evaluation of a robust, clinically useful CPR is anything but straightforward, adherence to the plethora of methodological standards, recommendations and frameworks at each stage will assist in the development of a rigorous CPR that has the potential to contribute usefully to clinical practice and decision-making and have a positive impact on patient care.

Prospective Validation of a Checklist to Predict Short-term Death in Older Patients After Emergency Department Admission in Australia and Ireland

BACKGROUND

Emergency departments (EDs) are pressured environment where patients with supportive and palliative care needs may not be identified. We aimed to test the predictive ability of the CriSTAL (Criteria for Screening and Triaging to Appropriate aLternative care) checklist to flag patients at risk of death within 3 months who may benefit from timely end-of-life discussions.

METHODS

Prospective cohorts of >65-year-old patients admitted for at least one night via EDs in five Australian hospitals and one Irish hospital. Purpose-trained nurses and medical students screened for frailty using two instruments concurrently and completed the other risk factors on the CriSTAL tool at admission. Postdischarge telephone follow-up was used to determine survival status. Logistic regression and bootstrapping techniques were used to test the predictive accuracy of CriSTAL for death within 90 days of admission as primary outcome. Predictability of in-hospital death was the secondary outcome.

RESULTS

A total of 1,182 patients, with median age 76 to 80 years (IRE-AUS), were included. The deceased had significantly higher mean CriSTAL with Australian mean of 8.1 (95% confidence interval [CI] = 7.7-8.6) versus 5.7 (95% CI = 5.1-6.2) and Irish mean of 7.7 (95% CI = 6.9-8.5) versus 5.7 (95% CI = 5.1-6.2). The model with Fried frailty score was optimal for the derivation (Australian) cohort but prediction with the Clinical Frailty Scale (CFS) was also good (areas under the receiver-operating characteristic [AUROC] = 0.825 and 0.81, respectively). Values for the validation (Irish) cohort were AUROC = 0.70 with Fried and 0.77 using CFS. A minimum of five of 29 variables were sufficient for accurate prediction, and a cut point of 7+ or 6+ depending on the cohort was strongly indicative of risk of death. The most significant independent predictor of short-term death in both cohorts was frailty, carrying a twofold risk of death. CriSTAL's accuracy for in-hospital death prediction was also good (AUROC = 0.795 and 0.81 in Australia and Ireland, respectively), with high specificity and negative predictive values.

CONCLUSIONS

The modified CriSTAL tool (with CFS instead of Fried's frailty instrument) had good discriminant power to improve certainty of short-term mortality prediction in both health systems. The predictive ability of models is anticipated to help clinicians gain confidence in initiating earlier end-of-life discussions. The practicalities of embedding screening for risk of death in routine practice warrant further investigation.

Predicting mortality in patients treated differently: updating and external validation of a prediction model for nursing home residents with dementia and lower respiratory infections

OBJECTIVE

To evaluate whether a model that was previously developed to predict 14-day mortality for nursing home residents with dementia and lower respiratory tract infection who received antibiotics could be applied to residents who were not treated with antibiotics. Specifically, in this same data set, to update the model using recalibration methods; and subsequently examine the historical, geographical, methodological and spectrum transportability through external validation of the updated model.

DESIGN

1 cohort study was used to develop the prediction model, and 4 cohort studies from 2 countries were used for the external validation of the model.

SETTING

Nursing homes in the Netherlands and the USA.

PARTICIPANTS

157 untreated residents were included in the development of the model; 239 untreated residents were included in the external validation cohorts.

OUTCOME

Model performance was evaluated by assessing discrimination: area under the receiver operating characteristic curves; and calibration: Hosmer and Lemeshow goodness-of-fit statistics and calibration graphs. Further, reclassification tables allowed for a comparison of patient classifications between models.

RESULTS

The original prediction model applied to the untreated residents, who were sicker, showed excellent discrimination but poor calibration, underestimating mortality. Adjusting the intercept improved calibration. Recalibrating the slope did not substantially improve the performance of the model. Applying the updated model to the other 4 data sets resulted in acceptable discrimination. Calibration was inadequate only in one data set that differed substantially from the other data sets in case-mix. Adjusting the intercept for this population again improved calibration.

CONCLUSIONS

The discriminative performance of the model seems robust for differences between settings. To improve calibration, we recommend adjusting the intercept when applying the model in settings where different mortality rates are expected. An impact study may evaluate the usefulness of the two prediction models for treated and untreated residents and whether it supports decision-making in clinical practice.

Changing practice in dementia care in the community: developing and testing evidence-based interventions, from timely diagnosis to end of life (EVIDEM)

Background

The needs of people with dementia and their carers are inadequately addressed at all key points in the illness trajectory, from diagnosis through to end-of-life care. The EVIDEM (Evidence-based Interventions in Dementia) research and development programme (2007–12) was designed to help change this situation within real-life settings.

Objectives

The EVIDEM projects were (1) evaluation of an educational package designed to enhance general practitioners’ (GPs’) diagnostic and management skills; (2) evaluation of exercise as therapy for behavioural and psychological symptoms of dementia (BPSD); (3) development of a toolkit for managing incontinence in people with dementia living at home; (4) development of a toolkit for palliative care for people with dementia; and (5) development of practice guidance on the use of the Mental Capacity Act (MCA) 2005.

Design

Mixed quantitative and qualitative methods from case studies to large database analyses, including longitudinal surveys, randomised controlled trials and research register development, with patient and public involvement built into all projects.

Setting

General practices, community services, third-sector organisations and care homes in the area of the North Thames Dementia and Neurodegenerative Diseases Research Network local research network.

Participants

People with dementia, their family and professional carers, GPs and community mental health team members, staff in local authority social services and third-sector bodies, and care home staff.

Main outcome measures

Dementia management reviews and case identification in general practice; changes in behavioural and psychological symptoms measured with the Neuropsychiatric Inventory (NPI); extent and impact of incontinence in community-dwelling people with dementia; mapping of pathways to death of people with dementia in care homes, and testing of a model of collaborative working between primary care and care homes; and understandings of the MCA 2005 among practitioners working with people with dementia.

Results

An educational intervention in general practice did not alter management or case identification. Exercise as a therapy for BPSD did not reduce NPI scores significantly, but had a significant positive effect on carer burden. Incontinence is twice as common in community-dwelling people with dementia than their peers, and is a hidden taboo within a stigma. Distinct trajectories of dying were identified (anticipated, unexpected and uncertain), and collaboration between NHS primary care and care homes was improved, with cost savings. The MCA 2005 legislation provided a useful working framework for practitioners working with people with dementia.

Conclusions

A tailored educational intervention for general practice does not change practice, even when incentives, policy pressure and consumer demand create a favourable environment for change; exercise has potential as a therapy for BPSD and deserves further investigation; incontinence is a common but unrecognised problem for people with dementia in the community; changes in relationships between care homes and general practice can be achieved, with benefits for people with dementia at the end of life and for the UK NHS; application of the MCA 2005 will continue to improve but educational reinforcements will help this. Increased research capacity in dementia in the community was achieved. This study suggests that further work is required to enhance clinical practice around dementia in general practice; investigate the apparent beneficial effect of physical activity on BPSD and carer well-being; develop case-finding methods for incontinence in people with dementia; optimise working relationships between NHS staff and care homes; and reinforce practitioner understanding of the MCA 2005.

Caregivers' experiences seeking hospice care for loved ones with dementia

As the prevalence of dementia continues to grow, informal caregivers face unique challenges as they approach the end of life, and access to support and palliative care is often limited. I used a phenomenological approach to explore the experiences of caregivers actively seeking formal end-of-life care, in particular hospice care, for a loved one with dementia. In-depth interviews with 11 caregivers about 14 patients revealed five themes, including: setting the stage for heartbreak, reaching the boiling point, getting through the front lines, settling for less, and welcoming death. Nurses must recognize the complex needs of caregivers, educate caregivers on the disease process, and adjust to palliative goals sooner to meet the needs of caregivers. Prevalence of these issues must be further examined through quantitative study to evaluate the need to reconsider current hospice eligibility criteria based on prognosis.

[Evaluation of a family booklet on comfort care in dementia by professional and family caregivers]

Families of nursing home residents with dementia are usually involved in care and treatment decisions. To this end, family needs to be informed on the course of the dementia and possible palliative care. Based on a Canadian booklet, we developed an adapted version for use in the Netherlands. Elderly care physicians (n = 30), nurses (n = 38), and bereaved families (n = 59) evaluated the booklet and possible implementation strategies. All respondents confirmed that in general, there is a need of an information brochure on comfort care and end-of-life issues for families. Most (93%) families believed they would have found the booklet useful when received earlier. Compared to the physicians, nurses more frequently found the booklet useful to most or all families (p = 0.04). Acceptance, as measured on an 8-item scale, was highest among families and lowest among physicians. Overall usefulness was often perceived as high (means 7.9 to 8.3; scale range 0-10; SD 0.9 to 1.4) and did not differ across groups of respondents (p = 0.29). All respondents agreed that professional caregivers should have a role in providing the booklet. Additionally, half (53%; no difference across groups) favoured availability of the booklet through families' own initiative; some already before admission. In conclusion, there is a high need for written information on palliative care. The booklet is highly appreciated. A further improved version may support professional and family caregivers in practice.

Antibiotics and mortality in patients with lower respiratory infection and advanced dementia

OBJECTIVES

To describe long-term mortality rate and to assess associations between mortality rate and antibiotic treatment of lower respiratory infection in patients with advanced dementia; antibiotic treatment allocation was independent of mortality risk-leaving less room for biased associations than in previous multicenter observational studies.

DESIGN

Prospective study (2004-2009). Multilevel Cox proportional hazard analyses with adjustment for mortality risk were used to assess associations between antibiotics and mortality using time-dependent covariates.

SETTING

A US Department of Veterans Affairs nursing home.

PARTICIPANTS

Ninety-four residents with advanced dementia who developed 109 episodes.

MEASUREMENTS

Survival, treatment, mortality risk, illness severity, fluid intake, and several other patient characteristics.

RESULTS

Ten-day mortality was 48%, and 6-month mortality was 74%. Antibiotics were used in 77% of episodes. Overall, antibiotics were not associated with mortality rate (Hazard Ratio [HR] 0.70, Confidence Interval [CI] 0.38-1.30); however, antibiotics were associated with reduced 10-day mortality rate (HR 0.51, CI, 0.30-0.87; rate after 10 days: 1.5, CI 0.42-5.2). Benefit from antibiotics was less likely with inadequate fluid intake, and when experiencing the first episode.

CONCLUSION

In our sample of male nursing home residents with advanced dementia and lower respiratory infection, mortality was substantial despite antibiotic treatment. Antibiotics prolonged life but in many cases only for several days. Treatment decisions should take into account that antibiotics may delay death but may also prolong the dying process, indicating a need for accurate prediction of mortality and study of characteristics that may alter effectiveness of antibiotics.

Framework for the impact analysis and implementation of Clinical Prediction Rules (CPRs)

Clinical Prediction Rules (CPRs) are tools that quantify the contribution of symptoms, clinical signs and available diagnostic tests, and in doing so stratify patients according to the probability of having a target outcome or need for a specified treatment. Most focus on the derivation stage with only a minority progressing to validation and very few undergoing impact analysis. Impact analysis studies remain the most efficient way of assessing whether incorporating CPRs into a decision making process improves patient care. However there is a lack of clear methodology for the design of high quality impact analysis studies.We have developed a sequential four-phased framework based on the literature and the collective experience of our international working group to help researchers identify and overcome the specific challenges in designing and conducting an impact analysis of a CPR.There is a need to shift emphasis from deriving new CPRs to validating and implementing existing CPRs. The proposed framework provides a structured approach to this topical and complex area of research.
