The use of proxies and proxy-reported measures: a report of the international society for quality of life research (ISOQOL) proxy task force

Relationship Between Parental Distress and Proxy Symptom Reports in Pediatric Palliative Care

CONTEXT

In pediatric palliative care (PPC), patients often are not able to report symptoms so proxy reports from parents are used. Whether psychological distress in the proxies affects reports of patients' symptoms is unknown.

OBJECTIVE

To measure the influence of parents' distress on proxy-reported scores regarding symptoms by analyzing pairs of parents reporting on the same child.

METHODS

In a large prospective cohort study of PPC patients, we collected parents' reports of child symptoms (Memorial Symptom Assessment Scale) and their own psychological distress (Kessler-6). In this quasi-experimental design study, we examined data from pairs of parents reporting symptoms for the same child. Using regression modelling, we estimated the association between parental distress scores and patient total symptom scores across the entire sample accounting for clustering within families, and then measured the association within-families of the absolute differences of the two parents' distress and the difference in their symptom scores.

RESULTS

Among 152 parents in 76 families, 50.0% were female, 80.9% were White, and the mean age was 36.4 (SD 9.0) years. Across the sample, each 1-point increase in reported parental distress was associated with a 1.07 (95% CI, 0.87-1.28; P < 0.001) increase in proxy-reported patient symptom score. Within families, relative to the other parent, each 1-point increase in the difference of the distress scores was associated with a 0.33-point (95% CI, 0.32-0.35; P = 0.006) increase in the difference in symptom scores.

CONCLUSION

Psychological distress appears to influence proxy reports of symptoms which has implications for future research and clinical practice.

Feasibility of implementing a codesigned patient reported outcome measures (PROMs) collection system for older adults in acute and sub-acute hospital settings

PURPOSE

To test the feasibility of a co-designed PROMs collection system for hospitalised older adults.

METHODS

A mixed-methods feasibility study was conducted sequentially across one acute and one sub-acute ward, over a 12-week period. Patients aged ≥ 60 years who discharged from hospital were eligible. The EQ-5D-5L with added items on fatigue and cognition was administered on discharge and at 3-6 months post-discharge. Administration was by either a research assistant or volunteer using a variety of modes (tablet computer, phone, SMS). Feasibility was evaluated using a feasibility framework to capture demand, implementation, practicality, and acceptability. Descriptive statistics were applied. Interviews were conducted with volunteers and analysed using deductive content analysis.

RESULTS

Completion rates indicated high demand (discharge = 84%, n = 110/131; follow-up = 81%, n = 90/110). At discharge, most completed PROMs on the tablet (57%) and 9% were administered by a volunteer. Most required assistance using the tablet (67%) and the average time to administer PROMs was longest for the tablet (17.9 min, SD = 3.3), followed by phone (8.8 min, SD = 4.4) and SMS (1.3 min, SD = 0.5). Fewer participants reported acceptability with using the tablet (61%) compared to SMS (100%). At follow-up, most completed PROMs on the phone (82%) and the average time to administer PROMs was less than discharge (4.9 vs. 13.4 min). Volunteers reported administering PROMs to unwell patients was challenging.

CONCLUSION

A co-designed PROMs collection system demonstrated feasibility in hospitalised older adults with phone and SMS having greatest acceptability. Administration of PROMs by volunteers was not feasible.

Head-to-Head Comparisons of the Distributional Characteristics and Measurement Properties of the 3-Level and 5-Level Versions of the EQ-5D-Y: A Systematic Review

OBJECTIVES

This systematic review compared the distributional characteristics and measurement properties of EuroQol's EQ-5D-Y-3L and EQ-5D-Y-5L instruments, using results from published head-to-head comparative studies.

METHODS

The review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-COnsensus-based Standards for the selection of health Measurement INstruments (PRISMA-COSMIN) guideline. We searched 8 databases up to February 14, 2024 for studies on the measurement properties and distributional characteristics (missing data, ceiling/floor effects, consistency, and informativity) of both EQ-5D-Y versions. Measurement quality was assessed in terms of the proportion of tests meeting COSMIN recommended criteria for reliability, validity, and responsiveness.

RESULTS

Eighteen studies were included. The Y-5L reduced ceiling effects by 0.8% to 16.5% and had a slightly higher evenness index, indicating greater informativity. Both versions showed sufficient construct validity across patient and general population samples, with the Y-5L slightly outperforming the Y-3L in known-group validity. Both the Y-3L and Y-5L versions showed sufficient test-retest reliability for mobility, pain/discomfort, and worried, sad, or unhappy and inconsistent reliability for looking after myself and usual activities, indicating similar performance across these dimensions. The Y-5L showed better responsiveness (standardized effect size range = 0.03-2.05) than Y-3L (range = 0.13-0.94). In proxy-reported data, the Y-5L appears to have slightly lower test-retest reliability than the Y-3L, despite demonstrating better agreement with self-reported data.

CONCLUSIONS

Both EQ-5D-Y versions demonstrated varying psychometric performances across the evaluated populations, with the Y-5L slightly outperforming the Y-3L in responsiveness and proxy-child agreement. The availability of the Y-5L expands the options of health-related quality-of-life instruments for assessing pediatric populations. Further research is needed to assess its performance across diverse populations and administrative modes.

Proxy reporting in health: a scoping review of instructions, perspectives, and reporting experiences

BACKGROUND

Informal carers ('proxies'), who typically provide unpaid care and have a personal relationship with the care recipient, are often asked to report on the health of individuals who are unable to self-report. However, this task is not without its challenges. Little is known about how proxies approach this task, which poses challenges for optimal questionnaire design.

PURPOSE

The review had three aims: (1) to identify the questionnaire perspective instructions provided to proxies i.e., whether the proxy was asked to answer from their own (proxy-proxy) or the person's (proxy-patient) perspective when reporting, (2) identify which perspective instruction the proxies followed, if reported, and (3) what information, if any, was captured about the proxy's experience of reporting about someone else. In the proxy-proxy perspective, proxies report from their own perspective, but in the proxy-patient perspective they report from the perspective of the person living with the condition.

METHODS

A systematic search was conducted across Medline, Psych Info, CINAHL, and Embase. Only published articles meeting the criteria of informal carers providing proxy reports for adults were considered.

RESULTS

Of 5816 publications, 60 articles were eligible for full-text review, and 12 were included for data extraction. Instructions varied, with proxies asked to adopt both proxy-proxy and proxy-patient perspectives in eight studies and only the proxy-patient in four of them. Whether proxies followed the provided instructions consistently is not known. Proxies' reporting experiences were not reported in the included studies.

CONCLUSION

Proxies are provided with different perspective instructions, but proxy adherence to instructions is not known. Additionally, proxy reporting experience was not described. Providing clear instructions, evaulating proxy adherence to instructions and collecting proxies' reporting experiences can inform optimal questionnaire design to help proxies better report about the health of others.

Participation at home of adults with multiple disabilities and influencing factors from their parents' perspective

PURPOSE

To understand participation at home of adults with multiple disabilities and the indicators of their engagement from the parents' perspective as well as to explore the influencing environmental factors.

METHODS

A qualitative, descriptive design was used. Participants had to be the parent of an adult presenting multiple disabilities aged between 21 and 65 with no degenerative diagnosis. Semi-structured interviews were conducted using an interview guide, anchored in the Human Development Model - Disability Creation Process and developed through an iterative process. Data were analyzed using a 6-step qualitative analysis process.

RESULTS

The majority (5/8) of participating parents were aged between 56 and 61 years and were the parents of an adult with multiple disabilities aged between 21 and 41. Two themes for participation were generated: communication to build relationships, and they are disabled, but not so much whereas four themes relating to environmental factors were generated: context as a determinant of meaningful activity, the effects of the caregiver's attitude on social participation, the importance of the relationship of trust, and facilitating participation through adaptations.

CONCLUSION

Non-verbal communication and context of realization of activities of adults with multiple disabilities should be considered as they contribute to making participation meaningful.

Mental health and mental health problems among users of AAC: a scoping review

Functional communication is crucial for mental health and for coping with mental health problems. People with disabilities are at increased risk of mental health problems, and people who use augmentative and alternative communication (AAC) are reported to be at greater risk of depression and anxiety than people without impairments. This scoping review summarizes existing knowledge about the mental health and mental health problems of people who use AAC. The review includes nine publications, published between 2001 and 2022. These mainly report on adults and elderly people who use AAC. Four of the nine publications included people who use AAC due to acquired impairments. None of the studies reported the prevalence of mental health problems and only a few addressed factors of positive mental health. The results indicate a shortage of theoretical accounts for most of the publications included, and the publications are not built on each other. The scarcity of knowledge is discussed in relation to the idea that the need for communicative support is a need based on communicative functioning rather than any diagnostic category and thus not visible in much of the health literature based on diagnostic categories. Several implications for practice and research are suggested.

Valuing quality of life for economic evaluations in cancer: navigating multiple methods

INTRODUCTION

Utility values offer a quantitative means to evaluate the impact of novel cancer treatments on patients' quality of life (QoL). However, the multiple methods available for valuing QoL present challenges in selecting the most appropriate method across different contexts.

AREAS COVERED

This review provides cancer clinicians and researchers with an overview of methods to value QoL for economic evaluations, including standalone and derived preference-based measures (PBMs) and direct preference elicitation methods. Recent developments are described, including the comparative performance of cancer-specific PBMs versus generic PBMs, measurement of outcomes beyond health-related QoL, and increased use of discrete choice experiments to elicit preferences. Recommendations and considerations are provided to guide the choice of method for cancer research.

EXPERT OPINION

We foresee continued adoption of the QLU-C10D and FACT-8D in cancer clinical trials given the extensive use of the EORTC QLQ-C30 and FACT-G in cancer research. While these cancer-specific PBMs offer the convenience of eliciting utility values without needing a standalone PBM, researchers should consider potential limitations if they intend to substitute them for generic PBMs. As the field advances, there is a greater need for consensus on the approach to selection and integration of various methods in cancer clinical trials.

Challenges and Recommendations for Proxy Reporting in Aging Research: A Brief Commentary

The US has an aging population that is under-represented in research. Many older adults face barriers to research participation, such as mobility issues, comorbidities, and declining physical and cognitive health, which make it harder for them to understand study processes and give informed consent. Proxies can be family members, paid or unpaid caregivers, or healthcare providers who provide health information for older adults. Proxy reporting is an important resource in aging research, but it is fraught with several challenges that can impact data accuracy and validity. In this paper, we describe these challenges and possible solutions to enhance proxy reporting and the participation of older adults in aging research.

Long-term durability between parent and child patient-reported outcomes in eosinophilic esophagitis

BACKGROUND

Because young children cannot self-report symptoms, there is a need for parent surrogate reports. Although early work suggested parent-child alignment for eosinophil esophagitis (EoE) patient-reported outcomes (PROs), the longitudinal alignment is unclear.

OBJECTIVE

We sought to assess the agreement and longitudinal stability of PROs between children with EoE and their parents.

METHODS

A total of 292 parent-child respondents completed 723 questionnaires over 5 years in an observational trial in the Consortium of Eosinophilic Gastrointestinal Disease Researchers. The change in and agreement between parent and child Pediatric Eosinophilic Esophagitis Symptom Score version 2 (PEESSv2.0) and Pediatric Quality of Life Eosinophilic Esophagitis Module (PedsQL-EoE) PROs over time were assessed using Pearson correlation and Bland-Altman analyses. Clinical factors influencing PROs and their agreement were evaluated using linear mixed models.

RESULTS

The cohort had a median disease duration equaling 3.7 years and was predominantly male (73.6%) and White (85.3%). Child and parent PEESSv2.0 response groups were identified and were stable over time. There was strong correlation between child and parent reports (PEESSv2.0, 0.83;PedsQL-EoE, 0.74), with minimal pairwise differences for symptoms. Longitudinally, parent-reported PedsQL-EoE scores were stable (P ≥ .32), whereas child-reported PedsQL-EoE scores improved (P = .026). A larger difference in parent and child PedsQL-EoE reports was associated with younger age (P < .001), and differences were driven by psychosocial PRO domains.

CONCLUSIONS

There is strong longitudinal alignment between child and parent reports using EoE PROs. These data provide evidence that parent report is a stable proxy for objective EoE symptoms in their children.

Seeking residents' views regarding Australian residential aged care: A scoping review

OBJECTIVE

This scoping review aimed to explore topics on which the views of residents of Australian residential aged care facilities (RACFs) have been sought.

METHODS

Scoping review methodology as outlined by Arksey and O'Malley was used to identify, explore and report on the range of literature regarding views of RACF residents. Seven electronic databases were searched using broad search terms relevant to the RACF context. Descriptive numerical analysis was completed for publication year, journal name and target profession, research methods and participant types. Thematic analysis then focussed on the aims of the included studies.

RESULTS

Four thousand two hundred and ninety studies were screened, and 104 publications met the inclusion criteria. A broad range of topics were explored by researchers, with the largest number of papers focused on residents' views of systems within RACFs (n = 24) and new programs and interventions (n = 21). Smaller topic areas included health conditions and health-care services (n = 13), socialisation (n = 13), physical activity (n = 3), self-care (n = 4), leisure (n = 4), general everyday life (n = 20) and aspects of the residential aged care environment (n = 15). There was limited exploration of meaningful activity (n = 13). The inclusion of residents with cognitive impairment was inconsistent, and the voices of other stakeholders were often privileged.

CONCLUSIONS

Voices of residents must be heard in order to prioritise the health and well-being of this population. More research which focuses on what is important to residents is needed and must include residents with cognitive impairment more effectively. Identification of optimal research methods with this population would make an important contribution in this area.

Understanding the influence of different proxy perspectives in explaining the difference between self-rated and proxy-rated quality of life in people living with dementia: a systematic literature review and meta-analysis

PURPOSE

Proxy assessment can be elicited via the proxy-patient perspective (i.e., asking proxies to assess the patient's quality of life (QoL) as they think the patient would respond) or proxy-proxy perspective (i.e., asking proxies to provide their own perspective on the patient's QoL). This review aimed to identify the role of the proxy perspective in explaining the differences between self-rated and proxy-rated QoL in people living with dementia.

METHODS

A systematic literate review was conducted by sourcing articles from a previously published review, supplemented by an update of the review in four bibliographic databases. Peer-reviewed studies that reported both self-reported and proxy-reported mean QoL estimates using the same standardized QoL instrument, published in English, and focused on the QoL of people with dementia were included. A meta-analysis was conducted to synthesize the mean differences between self- and proxy-report across different proxy perspectives.

RESULTS

The review included 96 articles from which 635 observations were extracted. Most observations extracted used the proxy-proxy perspective (79%) compared with the proxy-patient perspective (10%); with 11% of the studies not stating the perspective. The QOL-AD was the most commonly used measure, followed by the EQ-5D and DEMQOL. The standardized mean difference (SMD) between the self- and proxy-report was lower for the proxy-patient perspective (SMD: 0.250; 95% CI 0.116; 0.384) compared to the proxy-proxy perspective (SMD: 0.532; 95% CI 0.456; 0.609).

CONCLUSION

Different proxy perspectives affect the ratings of QoL, whereby adopting a proxy-proxy QoL perspective has a higher inter-rater gap in comparison with the proxy-patient perspective.

Poststroke Communication Ability Predicts Patient-Informant Discrepancies in Reported Activities and Participation

BACKGROUND

Participation in life situations has been identified by people with aphasia (PWA) as an ultimate outcome of rehabilitation and is often measured with patient-reported outcome measures (PROMs) or informant-reported measures. It is known that PWA and informants do not always produce similar scores on measures of activities and participation. However, systematic differences between PWA and informants and the causes of these differences are not well understood. Here, we investigated these differences as a function of language impairment, perceived level of activity and participation success, and depressive symptoms.

METHOD

Participants were 29 PWA-informant dyads who completed a performance-based language assessment and three measures related to different aspects of activities and participation. Outcome variables were PWA-informant difference scores in the activities and participation measures.

RESULTS

PWA ratings of activities and participation were not statistically significantly associated with performance-based language severity. Hierarchical regression models with both language impairment and informant-reported scores as predictor variables explained 53%-71% of the variance in PWA-informant difference scores (all p < .05). In particular, mild communication challenges were associated with the PWA reporting significantly worse participation than the informant perceived. In contrast, more severe communication challenges were associated with the PWA reporting significantly better participation than the informant perceived.

DISCUSSION

These findings highlight the importance of measuring participation by PROM. The PWA's experience of participation is not related to their level of language impairment and is predictably different from their care partners' perspective. As others have also reported, "mild" aphasia is not so mild to the PWA. Similarly, "severe" may not be so severe to the PWA. Further research is needed to connect these findings with counseling and caregiver education. Research on response processes (e.g., response shift) is also warranted.

Healthcare consumer acceptability of routine use of the EQ-5D-5L in clinical care: a cross-sectional survey

PURPOSE

Patient reported outcome measures, such as the EQ-5D-5L, provide a measure of self-perceived health status or health-related quality of life. Understanding the consumer acceptability of a patient reported outcome measure can help to decide about its implementation across a healthcare organisation and possibly increase the likelihood of its use in clinical care. This study established the acceptability of the EQ-5D-5L from the perspective of clients receiving healthcare, and determined if acceptability varied by client sub-types.

METHODS

A cross-sectional survey explored clients' experience of the EQ-5D-5L. Eligible clients were aged ≥ 18 years and completed the EQ-5D-5L on admission and discharge to one of two multi-disciplinary community health services. Likert scale items explored acceptability, and open-ended questions determined if the EQ-5D-5L reflects experience of illness. Associations between acceptability and client characteristics were established using χ2 test. Open-ended questions were analysed using content analysis.

RESULTS

Most of the 304 clients (mean age 70 years, SD 16) agreed that the EQ-5D-5L: was easy to use/understand (n = 301, 99%) and useful (n = 289, 95%); improved communication with their therapist (n = 275, 90%); and made them feel more in control of their health (n = 276, 91%). Most clients also agreed that they wished to continue using the EQ-5D-5L (n = 285, 93%). Clients aged ≥ 60 years reported lower acceptability. Clients noted that the EQ-5D-5L did not capture experience of illness related to fatigue, balance/falls, cognition, and sleep.

CONCLUSION

The EQ-5D-5L is acceptable for use in care but does not capture all aspects of health relevant to clients, and acceptability varies by subgroup.

Contrasting Views of Autism Spectrum Traits in Adults, Especially in Self-Reports vs. Informant-Reports for Women High in Autism Spectrum Traits

There is uncertainty among researchers and clinicians about how to best measure autism spectrum dimensional traits in adults. In a sample of adults with high levels of autism spectrum traits and without intellectual disability (probands, n = 103) and their family members (n = 96), we sought to compare self vs. informant reports of autism spectrum-related traits and possible effects of sex on discrepancies. Using correlational analysis, we found poor agreement between self- and informant-report measures for probands, yet moderate agreement for family members. We found reporting discrepancy was greatest for female probands, often self-reporting more autism-related behaviors. Our findings suggest that autism spectrum traits are often underrecognized by informants, making self-report data important to collect in clinical and research settings.

Predictors of Deterioration in Mental Well-Being and Quality of Life among Family Caregivers and Older People with Long-Term Care Needs during the COVID-19 Pandemic

BACKGROUND

During the COVID-19 pandemic, reduced access to care services and fear of infection prompted families to increase home care for their older relatives with long-term care needs. This had negative effects on both members of the caring dyad, impacting their quality of life (QoL) and mental well-being. This study investigated the factors that influenced the mental well-being and QoL of 239 dyads, before and after the first pandemic wave in Italy.

METHODS

Data were collected through a survey on the use of health and social care services and interventions by older care recipients living in the community and their family caregivers. Factors associated with deterioration of mental well-being and QoL in older care recipients (mean age 86.1 years old) and their family caregivers after the pandemic were studied.

RESULTS

The importance attached by family caregivers to the skills and training of healthcare professionals was a protective factor against the deterioration in the well-being of older care recipients. Similarly, the importance associated by family caregivers to the help received from healthcare professionals was a protective factor for QoL. Financial hardship of older care recipients was a risk factor for deterioration in caregivers' mental well-being, while support from other family members was a protective factor for QoL.

CONCLUSIONS

The presence of attentive healthcare professionals, a supportive family environment, and economic support can reduce the burden on both the caregiver and the older care recipient. These aspects need to be considered in any future emergency situation and when planning care services for community-dwelling older people.

Child-Parent Agreement in the Assessment of Health-Related Quality of Life Using the CHU9D and the PedsQLTM

OBJECTIVE

This study examined the inter-rater agreement between child-self and parental proxy health-related quality of life (HRQoL) ratings (overall and domain level) using two different generic child-specific measures, the Child Health Utility 9D (CHU9D) and the Pediatric Quality of Life Inventory (PedsQLTM), in a community-based sample of Australian children. A secondary objective was to investigate the impact of age on child-parent agreement across the dimensions of the two measures.

METHODS

A total of 85 child-parent dyads (children aged 6-12 years) recruited from the community completed the self and proxy versions of the CHU9D and the PedsQLTM, respectively. The inter-rater agreement was estimated using Concordance Correlation Coefficients (CCC) and Gwet's Agreement Coefficient (AC1) for the overall sample and across age-groups.

RESULTS

Agreement was low for overall HRQoL for both the CHU9D (CCC = 0.28) and the PedsQLTM (CCC = 0.39). Across the CHU9D dimensions, agreement was the highest for 'sad' (AC1 = 0.83) and lowest for 'tired' (AC1 = 0.31). The PedsQLTM demonstrated stronger agreement (AC1 = 0.41-0.6) for the physical health dimension but weaker for the psychosocial dimensions (AC1 < 0.4). Except for the 'tired' dimension, agreement was consistent across age-groups with the CHU9D, whilst the PedsQLTM showed poor agreement for most of the psychosocial health items among the older age-groups only (8-10 and 11-12 years).

CONCLUSION

This study highlights that the agreement between child and parent proxy reported HRQoL may be influenced by both the measure used and the age of the child. These findings may have implications for the economic evaluation of healthcare interventions and services in child populations when both child and proxy perspectives are considered in the assessment of child HRQoL.

Development of consensus-based considerations for use of adult proxy reporting: an ISOQOL task force initiative

AIMS

Many large-scale population-based surveys, research studies, and clinical care allow for inclusion of proxy reporting as a strategy to collect outcomes when patients are unavailable or unable to provide reliable self-report. Prior work identified an absence of methodological guidelines regarding proxy reporting in adult populations, including who can serve as a proxy, and considerations for data collection, analysis, and reporting. The primary objective of this work by the ISOQOL Proxy Task Force was to review documents and clinical outcome assessment measures with respect to proxy reporting and to develop, through consensus, considerations for proxy reporting.

METHODS

We assembled an international group with clinically relevant and/or methodological expertise on proxy use in adult populations. We conducted a targeted review of documentation based on regulatory, non-regulatory, professional society, and individual measure sources. Using a standardized collection form, proxy-related information was extracted from each source including definitions of a proxy, characteristics of a proxy, domains addressable or addressed by a proxy, and observer-reporting.

RESULTS

The definition of proxy was inconsistent across 39 sources, except regulatory documents which defined a proxy as a person other than the patient who reports on an outcome as if she/he were the patient. While proxy report was discouraged in regulatory documentation, it was acknowledged there were instances where self-report was impossible. Many documentation sources indicated proxies would be well-justified in certain contexts, but did not indicate who could act as a proxy, when proxies could be used, what domains of patient health they could report on, or how data should be reported. Observer-reported outcomes were typically defined as those based on observed behaviors, however there was not a consistent differentiation between proxy and observer reporting. Based on information extracted from these resources, we developed a checklist of considerations when including proxy-reported measures or using proxies in study design, data collection, analysis, interpretation and reporting of proxy reported data.

CONCLUSION

Our targeted review highlights a lack of clarity in capturing, interpreting and reporting data from proxies in adult populations. We provide a checklist of considerations to assist researchers and clinicians with including proxies in research studies and clinical care. Lastly, our review identified areas where further guidance and future research are necessary.

Key considerations to reduce or address respondent burden in patient-reported outcome (PRO) data collection

Patient-reported outcomes (PROs) are used in clinical trials to provide evidence of the benefits and risks of interventions from a patient perspective and to inform regulatory decisions and health policy. The collection of PROs in routine practice can facilitate monitoring of patient symptoms; identification of unmet needs; prioritisation and/or tailoring of treatment to the needs of individual patients and inform value-based healthcare initiatives. However, respondent burden needs to be carefully considered and addressed to avoid high rates of missing data and poor reporting of PRO results, which may lead to poor quality data for regulatory decision making and/or clinical care.

Agreement between older adult patient and caregiver proxy symptom reports

BACKGROUND

Proxy report is essential for patients unable to complete patient-reported outcome (PRO) measures themselves and potentially beneficial when the caregiver perspective can complement patient report. In this study, we examine agreement between self-report by older adults and proxy report by their caregivers when completing PROs for pain, anxiety, depression, and other symptoms/impairments.

METHODS

Four PROs were administered by telephone to older adults and their caregivers followed by re-administration within 24 h in a random subgroup. The PROs included the PHQ-9 depression, GAD-7 anxiety, PEG pain, and SymTrak multi-dimensional symptom and functional status scales.

RESULTS

The sample consisted of 576 older adult and caregiver participants (188 patient-caregiver dyads, 200 patients without identified caregiver). The four measures had good internal (Cronbach's alpha, 0.76 to 0.92) and test-retest (ICC, 0.63 to 0.92) reliability whether completed by patients or caregivers. Total score and item-level means were relatively similar for both patient and caregiver reports. Agreement for total score as measured by intraclass correlation coefficient (ICC) was better for SymTrak-23 (0.48) and pain (0.58) than for anxiety (0.28) and depression (0.25). Multinomial modeling showed higher (worse) patient-reported scale scores were associated with caregiver underreporting, whereas higher caregiver task difficulty was associated with overreporting.

CONCLUSION

When averaged over individuals at the group level, proxy reports of PRO scores by caregivers tend to approximate patient reports. For individual patients, proxy report should be interpreted more cautiously for psychological symptoms as well as when patient-reported symptoms are more severe, or caregiver task difficulty is high.

Preferences for home care to enable home death among adult patients with cancer in late palliative phase - a grounded theory study

BACKGROUND

The wish to be cared for and to die at home is common among people with end-stage cancer in the western world. However, home deaths are declining in many countries. The aim of this study was to explore the preferences for home care over time to enable home death among adult patients with cancer in the late palliative phase.

METHODS

A qualitative method was applied according to grounded theory (Corbin & Strauss, 2008). Data was collected using individual interviews (n = 15) with nine adult patients. One to two follow up interviews were conducted with four patients. Sampling, data collection and constant comparative analysis were undertaken simultaneously.

RESULTS

The findings are presented as a conceptual model of patients' preferences for care to enable home death. The core category "Hope and trust to get the care I need to die at home" showed that the preference to die at home seemed stable over time and did not change with deterioration in health status and progression in illness. Five categories were related to the core category. The categories "being in the present", "be safe and in charge" and "be seen and acknowledged" describe the patients' preferences to live a meaningful life until death and be the same person as always. These preferences depended on the categories describing characteristics of healthcare personnel and the organisation of care: "reliable, compassionate and competent healthcare personnel" and "timely, predictive, continuous and adaptive organisation".

CONCLUSION

An important preference over time was to be here and now and to live as meaningful a life as possible until death. Moreover, the patients preferred to retain control over their lives, to be autonomous and to be seen as the person they had always been. To achieve this, person-centred care provided by healthcare personnel with competence, skills and enough/ample time were required. In addition, home care needed to be organised in a way that ensured continuity and predictability. Systematic implementation of a person-centred care model and the use of advanced home care plans with continued re-evaluation for patients' preferences of home care were proposed measures to enable home death.
