Psychological well-being and quality of care: a factor-analytic examination of the palliative care outcome scale

Validation of the Integrated Palliative Care Outcome Scale (IPOS) in adults with cystic fibrosis

BACKGROUND

A primary palliative care model for cystic fibrosis (CF) recommends using the Integrated Palliative Care Outcome Scale (IPOS) for screening. Validation of the IPOS is needed.

METHODS

This secondary analysis utilized baseline data from a multisite trial of the palliative care model, Improving Life with CF. Adults with CF completed the IPOS, the Memorial Symptom Assessment Scale-CF (MSAS-CF), the CF Questionnaire-Revised (CFQ-R), the Patient Health Questionnaire (PHQ-8), the Generalized Anxiety Disorder (GAD-7), and the Perceived Stress Scale (PSS). IPOS structure was assessed using Cronbach α coefficients and a factor analysis. Construct validity was evaluated through bivariate relationships between IPOS scores and other questionnaire scores, and linear regressions assessing the extent to which the IPOS explains variance in quality-of-life domains.

RESULTS

The sample comprised 256 adults with complete IPOS data. α coefficients were .86 for the IPOS total score, .81 for the Physical Symptoms subscale, .79 for the Emotional Symptoms subscale, and .63 for the Communication/Practical Issues subscale. A two-component factor structure best aligned with the current subscales. IPOS scores were significantly associated with other measures; associations with MSAS-CF and CFQ-R subscales differentiated the IPOS Physical and Emotional subscales. The IPOS total score provided unique information about the variance in the CFQ-R Physical Functioning and Respiratory Symptoms domain scores.

CONCLUSIONS

In adults with CF, the IPOS has acceptable internal consistency and there is evidence of construct validity. These findings support adoption of the IPOS in the primary palliative care model for CF.

The Palliative Care Needs of Patients with Multiple Sclerosis, Parkinson's Related Diseases, and Motor Neurone Disease: A Secondary Analysis of the OPTCARE Neuro Trial Data

Background: Long-term neurological conditions include multiple sclerosis, Parkinson's-related diseases, and motor neurone disease. National and international guidelines recommend a palliative approach for advancing neurological disease, but there is little research describing and comparing the palliative care needs of these patients side by side. Objective: The aim of this study was to describe and compare the symptom burden and psychological distress of patients with multiple sclerosis, Parkinson's-related diseases, and motor neurone disease. Design: A cross-sectional secondary analysis of the OPTCARE Neuro trial data was performed. Setting/Subjects: Recruitment was from seven sites across the United Kingdom. Patients aged 18 years or older, severely affected by advanced stages of multiple sclerosis or Parkinson's-related diseases or any stage of motor neurone disease, with an unresolved symptom, and one other issue despite usual care were eligible. Measurements: Baseline demographics, Integrated Palliative care Outcome Scale (IPOS) Neuro, and Hospital Anxiety and Depression Scale (HADS) results were analyzed. Results: Data from 348 participants were analyzed. The mean IPOS Neuro-S24 score was 27, with no statistical difference found between groups (p = 0.341). The most common symptoms were poor mobility (68.5%), problems using legs (63%), and fatigue (34.8%). The HADS revealed that a quarter of participants met the criteria for a diagnosis of anxiety and depression. Conclusions: Multiple sclerosis, Parkinson's-related disease, and motor neurone disease patients who were eligible for the OPTCARE Neuro trial have unmet needs in the form of distressing physical and psychological symptoms. It is unclear how to address these needs. The answer likely lies in a collaborative approach between neurology, palliative care, psychology, and specialized allied health professionals. Future work should focus on investigating this.

Inclusion of Social Work in Comprehensive Palliative Care to Address Psychosocial Needs of Advanced Cancer Patients in Vietnam

The need for psychosocial care among patients with serious illnesses and available social work services continues to be great, especially in low- and middle-income countries. To evaluate the specific needs of Vietnamese cancer patients' quality of life (QOL), prevalence and severity of symptoms including depression and anxiety, and caregiver burden were assessed. Data on QOL, mood, caregiver burden, and other parameters were collected through face-to-face and phone- interviews. The QOL assessed by European Quality of Life scale version 5D (EQ5D) was poor but consistent with other studies of cancer patients. Assessed by the Hospital Anxiety and depression Scale (HADS), borderline or severe anxiety and depression were prevalent. Caregiver burden was high for one third of study participants. These results confirm the need among cancer patients for psycho-social support services that currently are rarely available in Vietnam. In light of this need, a comprehensive palliative care (CPC) service, including social work, was created to improve the quality of life (QOL) of Vietnamese cancer patients.

Strengthening Community End-of-Life Care through Implementing Measurement-Based Palliative Care

The increasing demand for palliative care in New Zealand presents a potential threat to the quality of service delivery. One strategy to overcome this is through the implementation of valid and reliable patient-reported outcome measures. This mixed-methods study aimed to (1) implement measurement-based palliative care (MBPC) in a community palliative care service in Auckland, New Zealand; (2) evaluate the clinical utility of MBPC perceived by clinicians; (3) describe patient characteristics as measured by the Integrated Palliative Care Outcome Scale (IPOS), the Australasian Modified Karnofsky Performance Scale (AKPS), and Phase of Illness (POI); and (4) evaluate the internal consistency of the IPOS. Participants were over 18 years of age from a community outpatient palliative care service. In a phased approach to implementation, healthcare staff were educated on each instrument used for patient assessment. Uptake and internal consistency were evaluated through descriptive statistics. An interpretive descriptive methodology was used to explore the clinical utility of MBPC through semi-structured interviews with seven clinical staff members. Individual patient assessments (n = 1507) were undertaken predominantly on admission, with decreasing frequency as patients advanced through to the terminal phase of their care. Mean total IPOS scores were 17.97 (SD = 10.39, α = 0.78). The POI showed that 65% of patients were in the stable phase, 20% were in the unstable phase, 9% were in the deteriorating phase, and 2% were in the terminal phase. Clinicians reported that MBPC facilitated holistic and comprehensive assessments, as well as the development of a common interdisciplinary language. Clinicians expressed discomfort using the psychosocial and spiritual items. Measurement-based palliative care was only partially implemented but it was valued by staff and perceived to increase the quality of service delivery. Future research should determine the optimal timing of assessments, cultural responsivity for Māori and Pacific patients, and the role of MBPC in decision support for clinicians.

Intelligent Palliative Care Based on Patient-Reported Outcome Measures

CONTEXT

The growth of patient reported outcome measures data in palliative care provides an opportunity for machine learning to identify patterns in patient responses signifying different phases of illness.

OBJECTIVES

The study will explore if machine learning and network analysis can identify phases in patient palliative status through symptoms reported on the Integrated Palliative Care Outcome Scale (IPOS).

METHODS

A partly cross-sectional and partially longitudinal observational study was undertaken using the Australasian Karnofsky Performance Scale (AKPS); Integrated Palliative Care Outcome Scale (IPOS); Phase of Illness (POI). Patient palliative records (n = 1507, 65% stable, 20% unstable, 9% deteriorating, 2% terminal) from 804 adult patients enrolled in a New Zealand palliative care service were analysed using a combination of statistical, machine learning and network analysis techniques.

RESULTS

Data from IPOS showed considerable variation with phase. Also, network analysis showed clear associations between items by phase. Six machine learning techniques identified the most important variables for predicting possible transition between phases of illness. Network analysis for all patients showed that Poor Appetite and Loss of Energy were central IPOS items, with Loss of Energy linked to Drowsiness, Shortness of Breath and Lack of Mobility on the one hand, and Poor Appetite linked to Nausea, Vomiting, Constipation and Sore and Dry Mouth on the other.

CONCLUSION

These preliminary results, when coupled with the latest technological developments in mobile apps and wearable technology, could point the way to increased use of digital therapeutics in continuous palliative care monitoring.

Psychometric Properties of the Persian Version of Palliative Care Outcome Scale (POS) in Adult Patients With Cancer

Background

Measuring the outcomes of palliative care plays an important role to improve the quality, efficiency, and availability of these services in patients with cancer. Using valid, reliable, and culturally appropriate tools has a considerable role to measure these outcomes. This study aimed to assess the psychometric properties of the translated version of the Palliative care Outcome Scale (POS).

Methods

This methodological study was conducted in two outpatient clinics related to Shohada Tajrish and Baqiyatallah hospitals in Tehran in 2019-2020. The translation was done using the Forward-Backward approach after gaining permission from the developer. Face validity was tested with 10 patients with cancer through cognitive interviewing, as well as content validity with four experts. Construct validity was performed by (n = 203) exploratory factor analysis and confirmation (N = 150). To assess the reliability, internal consistency was assessed by using Cronbach's alpha coefficient, and relative stability was assessed using the interclass correlation coefficient (ICC). Furthermore, interpretability and ceiling and floor effects were assessed.

Results

A total of 353 patients with cancer under palliative care were included in the study. Then, three psychological (30%), physical (12.25%), and social factors (12.08%) with a cumulative variance of 54.34% were extracted in exploratory factor analysis. Confirmatory factor analysis showed that the model has a good fit of information. Cronbach's alpha coefficient for scale was 0.719. Furthermore, the ICC was 0.812. The scale was interpretable, and ceiling and floor effects were 0%.

Conclusion

Persian version of the POS was evaluated as a valid and reliable tool. Therefore, it can be used by the clinician to monitor the consequences of palliative care in Iranian cancer patients.

The AMBER care bundle for hospital inpatients with uncertain recovery nearing the end of life: the ImproveCare feasibility cluster RCT

BACKGROUND

Patients admitted to hospital with a terminal illness and uncertain recovery often receive inconsistent care and do not have the opportunity to die in their preferred place of death. Previous end-of-life care packages, such as the Liverpool Care Pathway for the Dying Patient, have sometimes been badly implemented. The AMBER (Assessment; Management; Best practice; Engagement; Recovery uncertain) care bundle was developed to remedy this. It has not been evaluated in a randomised trial, but a definitive trial would face many hurdles.

OBJECTIVE

To optimise the design of and determine the feasibility of a pragmatic, multicentre, cluster randomised controlled trial of the AMBER care bundle compared with best standard care.

DESIGN

A feasibility cluster randomised controlled trial including semistructured interviews with patients and relatives, focus groups with health-care professionals, non-participant observations of multidisciplinary team meetings, a standard care survey, heat maps and case note reviews. Retrospective data were collected from the family or close friends of deceased patients via a bereavement survey.

SETTING

Four general medical wards at district general hospitals in England.

PARTICIPANTS

There were 65 participants (control, n = 36; intervention, n = 29). There were 24 interviews, four focus groups, 15 non-participant meeting observations, six case note reviews and three heat maps, and 15 of out 23 bereavement, standard care surveys were completed.

INTERVENTION

The AMBER care bundle is implemented by a nurse facilitator. It includes the development and documentation of a medical plan, consideration of outcomes, resuscitation and escalation status and daily plan revisiting. The AMBER care bundle encourages staff, patients and families to talk openly about their preferences and priorities should the worst happen.

MAIN OUTCOME MEASURES

Two 'candidate' primary outcomes were selected to be evaluated for a future definitive trial: Integrated Palliative care Outcome Scale patient/family anxiety and communication subscale and 'howRwe'. The secondary outcome measures were Integrated Palliative care Outcome Scale symptoms, Australian-modified Karnofsky Performance Status scale, EuroQol-5 Dimensions, five-level version, Client Service Receipt Inventory, recruitment rate, intervention fidelity and intervention acceptability.

RESULTS

Data were collected for 65 patients. This trial was not powered to measure clinical effectiveness, but variance and changes observed in the Integrated Palliative care Outcome Scale subscale indicated that this measure would probably detect differences within a definitive trial. It was feasible to collect data on health, social and informal care service use and on quality of life at two time points. The AMBER care bundle was broadly acceptable to all stakeholders and was delivered as planned. The emphasis on 'clinical uncertainty' prompted health-care professional awareness of often-overlooked patients. Reviewing patients' AMBER care bundle status was integrated into routine practice. Refinements included simplifying the inclusion criteria and improving health-care professional communication training. Improvements to trial procedures included extending the time devoted to recruitment and simplifying consent procedures. There was also a recommendation to reduce data collected from patients and relatives to minimise burden.

LIMITATIONS

The recruitment rate was lower than anticipated. The inclusion criteria for the trial were difficult to interpret. Information sheets and consent procedures were too detailed and lengthy for the target population. Health-care professionals' enthusiasm and specialty were not considered while picking trial wards. Participant recruitment took place later during hospital admission and the majority of participants were lost to follow-up because they had been discharged. Those who participated may have different characteristics from those who did not.

CONCLUSIONS

This feasibility trial has demonstrated that an evaluation of the AMBER care bundle among an acutely unwell patient population, although technically possible, is not practical or feasible. The intervention requires optimisation.

A brief, patient- and proxy-reported outcome measure in advanced illness: Validity, reliability and responsiveness of the Integrated Palliative care Outcome Scale (IPOS)

BACKGROUND

Few measures capture the complex symptoms and concerns of those receiving palliative care.

AIM

To validate the Integrated Palliative care Outcome Scale, a measure underpinned by extensive psychometric development, by evaluating its validity, reliability and responsiveness to change.

DESIGN

Concurrent, cross-cultural validation study of the Integrated Palliative care Outcome Scale - both (1) patient self-report and (2) staff proxy-report versions. We tested construct validity (factor analysis, known-group comparisons, and correlational analysis), reliability (internal consistency, agreement, and test-retest reliability), and responsiveness (through longitudinal evaluation of change).

SETTING/PARTICIPANTS

In all, 376 adults receiving palliative care, and 161 clinicians, from a range of settings in the United Kingdom and Germany.

RESULTS

We confirm a three-factor structure (Physical Symptoms, Emotional Symptoms and Communication/Practical Issues). Integrated Palliative care Outcome Scale shows strong ability to distinguish between clinically relevant groups; total Integrated Palliative care Outcome Scale and Integrated Palliative care Outcome Scale subscale scores were higher - reflecting more problems - in those patients with 'unstable' or 'deteriorating' versus 'stable' Phase of Illness (F = 15.1, p < 0.001). Good convergent and discriminant validity to hypothesised items and subscales of the Edmonton Symptom Assessment System and Functional Assessment of Cancer Therapy-General is demonstrated. The Integrated Palliative care Outcome Scale shows good internal consistency (α = 0.77) and acceptable to good test-retest reliability (60% of items k_w > 0.60). Longitudinal validity in form of responsiveness to change is good.

CONCLUSION

The Integrated Palliative care Outcome Scale is a valid and reliable outcome measure, both in patient self-report and staff proxy-report versions. It can assess and monitor symptoms and concerns in advanced illness, determine the impact of healthcare interventions, and demonstrate quality of care. This represents a major step forward internationally for palliative care outcome measurement.

Managing uncertain recovery for patients nearing the end of life in hospital: a mixed-methods feasibility cluster randomised controlled trial of the AMBER care bundle

BACKGROUND

The AMBER (Assessment, Management, Best Practice, Engagement, Recovery Uncertain) care bundle is a complex intervention used in UK hospitals to support patients with uncertain recovery. However, it has yet to be evaluated in a randomised controlled trial (RCT) to identify potential benefits or harms. The aim of this trial was to investigate the feasibility of a cluster RCT of the AMBER care bundle.

METHODS

This is a prospective mixed-methods feasibility cluster RCT. Quantitative data collected from patients (or proxies if patients lack capacity) were used (i) to examine recruitment, retention and follow-up rates; (ii) to test data collection tools for the trial and determine their optimum timing; (iii) to test methods to identify the use of financial resources; and (iv) to explore the acceptability of study procedures for health professionals and patients. Descriptive statistical analyses and thematic analysis used the framework approach.

RESULTS

In total, 894 patients were screened, of whom 220 were eligible and 19 of those eligible (8.6%) declined to participate. Recruitment to the control arm was challenging. Of the 728 patients screened for that arm, 647 (88.9%) were excluded. Overall, 65 patients were recruited (81.3% of the recruitment target of 80). Overall, many were elderly (≥80 years, 46.2%, n = 30, mean = 77.8 years, standard deviation [SD] = 12.3 years). Over half (53.8%) had a non-cancer diagnosis, with a mean of 2.3 co-morbidities; 24.6% patients (n = 16) died during their hospital stay and 35.4% (n = 23) within 100 days of discharge. In both trial arms, baseline IPOS subscale scores identified moderate patient anxiety (control: mean 13.3, SD 4.8; intervention: mean 13.3, SD 5.1), and howRwe identified a good care experience (control: mean 13.1, SD 2.5; intervention: mean 11.5, SD 2.1). Collecting quantitative service use and quality of life data was feasible. No patient participants regarded study involvement negatively. Focus groups with health professionals identified concerns regarding (i) the subjectivity of the intervention's eligibility criteria, (ii) the need to prognosticate to identify potential patients and (iii) consent procedures and the length of the questionnaire.

CONCLUSIONS

A full trial of the AMBER care bundle is technically feasible but impractical due to fundamental issues in operationalising the intervention's eligibility criteria, which prevents optimal recruitment. Since this complex intervention continues to be used in clinical care and advocated in policy, alternative research approaches must be considered and tested.

Tools Measuring Quality of Death, Dying, and Care, Completed after Death: Systematic Review of Psychometric Properties

Introduction

Measuring the quality of care at the end of life and/or the quality of dying and death can be challenging. Some measurement tools seek to assess the quality of care immediately prior to death; others retrospectively assess, following death, the quality of end-of-life care. The comparative evaluation of the properties and application of the various instruments has been limited.

Objective

This systematic review identified and critically appraised the psychometric properties and applicability of tools used after death.

Method

We conducted a systematic review according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by systematically searching MEDLINE, Embase, CINAHL, and PsycINFO for relevant studies. We then appraised the psychometric properties and the quality of reporting of the psychometric properties of the identified tools using the COSMIN (Consensus-based Standards for the selection of health Measurement Instruments) checklist. The protocol of this systematic review has been registered on PROSPERO (CRD42016047296).

Results

The search identified 4751 studies. Of these, 33 met the inclusion criteria, reporting on the psychometric properties of 67 tools. These tools measured quality of care at the end of life (n = 35), quality of dying and death (n = 22), or both quality of care at the end of life and dying and death (n = 10). Most tools were completed by family carers (n = 57), with some also completed by healthcare professionals (HCPs) (n = 2) or just HCPs (n = 8). No single tool was found to be adequate across all the psychometric properties assessed. Two quality of care at the end of life tools—Care of the Dying Evaluation and Satisfaction with Care at the End of Life in Dementia—had strong psychometric properties in most respects. Two tools assessing quality of dying and death—the Quality of Dying and Death and the newly developed Staff Perception of End of Life Experience—had limited to moderate evidence of good psychometric properties. Two tools assessing both quality of care and quality of dying and death—the Quality Of Dying in Long-Term Care for cognitively intact populations and Good Death Inventory (Korean version)—had the best psychometric properties.

Conclusion

Four tools demonstrated some promise, but no single tool was consistent across all psychometric properties assessed. All tools identified would benefit from further psychometric testing.

Change in multidimensional problems and quality of life over three months after HIV diagnosis: a multicentre longitudinal study in Kenya and Uganda

Background

Evidence on patient-reported outcomes of newly diagnosed HIV patients is scarce, and largely cross-sectional. This prospective cohort study describes the prevalence of, and changes in, patient-reported outcomes in the three months after HIV diagnosis, in 11 HIV outpatient centres in Kenya and Uganda.

Methods

Adults were recruited within 14 days of result, completing self-report measures four times at monthly intervals. Multilevel mixed-effects linear regression (quality of life continuous outcomes) and ordinal logistic regression (symptoms and concerns categorical outcomes) modelled change over time, with repeated observations grouped within individuals adjusted for demographic/clinical characteristics, and multiple imputation for missing data.

Results

438 adults were enrolled and 234 (53·4%) initiated ART. Improvement was found for MOS-HIV physical health (from 46·3 [95% CI 45·1–47·3], to 53·7 [95% CI 52.8–54·6], p < 0.001), and mental health (from 46·4 [95% CI 45·5–47·3] to 54·5 [95% CI 53·7–55·4], p < 0.001). POS subscale ‘interpersonal problems’ improved but remained burdensome (OR = 0·91, 95% CI = 0·87–0·94, p < 0.001; 22·7% reported severe problems at final time point). The scores for the existential POS subscale (OR = 0·95, 95% CI = 0.90–1·00, p = 0.056) and physical/psychological problems POS subscale (OR = 0·97, 95% CI = 0.92–1·02, p = 0.259) did not improve.

Participants who initiated ART had worsening physical/psychological (OR = 0·64, 95% CI = 0·41–0·99, p = 0·045) and interpersonal problems (OR = 0·64, 95% CI = 0·42–0·96, p = 0·033).

Conclusion

Although some self-reported outcomes improve over time, burden of interpersonal problems remains substantial and existential concerns do not improve.

A Rasch Analysis of the Integrated Palliative Care Outcome Scale

CONTEXT

Accurate assessment of a patient's palliative care needs is essential for the timely provision of treatment and support. The Integrated Palliative Care Outcome Scale (IPOS) is an ordinal measure possessing acceptable psychometric properties, but its ability to discriminate precisely between individual symptom levels has not been rigorously investigated.

OBJECTIVES

The study aimed to conduct Rasch analysis of the IPOS to evaluate and enhance precision of the instrument.

METHODS

Responses of 300 community-dwelling palliative care patients were subjected to Rasch analysis using the partial credit model.

RESULTS

Initial analysis supported the use of the Rasch model and acceptable reliability (person separation index = 0.77) was observed; however, unsatisfactory model fit was found. Local dependency between items was resolved through the creation of super-items, which increased model fit, reliability (person separation index = 0.80), and unidimensionality. There were no misfitting super-items or differential item functioning by age, rater, sex, or ethnicity. The IPOS showed satisfactory coverage of symptoms within the present clinical sample, with the ability to assess higher severity patients.

CONCLUSION

The modified IPOS showed excellent reliability for a clinical measure in assessing the overall palliative care needs of a patient. The provided ordinal-to-interval conversion table accounts for unique contribution of each symptom to the overall symptom burden and easy to use without the need to modify the original IPOS format.

Validity, Reliability, and Responsiveness of the Thai Palliative Care Outcome Scale Staff and Patient Versions Among Cancer Patients

BACKGROUND

Palliative care is now part of Universal Health Coverage goals. Measurement of person-centered outcomes is central to determining quality and effectiveness. Guidance in psychometrics requires tools applied in new settings to have their properties tested.

OBJECTIVES

To translate staff and patient versions of the Palliative care Outcome Scale (POS, version 2) into Thai, and to determine its psychometric properties among cancer patients in a Thai public hospital.

DESIGN

The Thai POS was subjected to cross-cultural translation: forward translation, backward translation, review by experts, and content validity index measurement. The patient-rated and staff-rated versions were completed by 379 nurses. We tested internal consistency, known-group comparison, responsiveness, and agreement.

SETTING/PARTICIPANTS

About 379 Thai cancer patients were admitted to Maharaj Nakorn Chiang Mai Hospital.

RESULTS

We found good internal consistency (Cronbach's alpha 0.9), good discrimination between known groups (significant difference in scores between high and low performance status groups; Z ranged from -9.95 to -7.80; P < 0.001), good responsiveness (improvements in at Time 2; Z ranged from -14.01 to -6.31; P < 0.001), and acceptable to good patient-staff agreement on ratings (weighted kappa range 0.31-0.73).

CONCLUSION

The Thai POS is valid and reliable. These findings enable researchers and clinicians to apply the POS in primary research and routine clinical practice to both determine the effectiveness of interventions and improve care. This is the first validation in the region of a multidimensional person-centered outcome measure designed specifically for patients and families with advanced disease.

Measuring health-related quality of life in patients with advanced cancer: a systematic review of self-administered measurement instruments

PURPOSE

Patient-reported outcome measures (PROMs) are becoming increasingly important in clinical practice. The implementation of PROMS in routine practice is challenging because information regarding psychometric quality of measurement instruments is fragmented and standardization is lacking. The aim of this study is to evaluate the quality of self-administered HRQoL measurement instruments for use in patients with advanced cancer in clinical practice.

METHODS

A systematic literature search was performed in PubMed, Embase, PsycINFO, and CINAHL to identify studies concerning self-administered HRQoL measurement instruments in patients with advanced cancer between January 1990 and September 2016. Quality of the measurement instruments was assessed by predefined criteria derived from the COSMIN checklist.

RESULTS

Sixty-nine articles relating to 39 measurement instruments met the inclusion criteria. Information regarding important measurement properties was often incomplete. None of the instruments performed sufficient on all measurement properties. Considering available information, the EORTC QLQ-C15-PAL appeared to have adequate psychometric properties, together with the EORTC QLQ-BM22.

CONCLUSIONS

Many of the existing HRQoL measurement instruments have not yet been evaluated in an adequate manner. Validation of self-administered HRQoL measurement instruments is an ongoing development and should be prioritized. This review contributes to improved clarity regarding the availability and quality of HRQoL measurement instruments for patients with advanced cancer and supports health care professionals in an adequate selection of suitable PROMs in clinical practice.

Quality of Life in Palliative Care

Introduction

A main goals of palliative care is to improve the health-related quality of life (QOL) of patients with advanced illnesses. The objective of this narrative review is to provide an updated synopsis on the use of QOL questionnaires in the palliative care setting.

Areas covers

Focusing on the palliative cares setting, we will define QOL, discuss how QOL instruments can be used clinically and in research, review approaches to validate these questionnaires, and how they can be used in utility analyses.

Expert opinion/commentary

Several QOL questionnaires, such as EORTC-QLQ-C30, McGill QOL questionnaire and EQ-5D have been validated in the palliative care setting. However, significant gaps impede their application, including lack of determination of their responsiveness to change and minimal clinically important differences, the need to conduct more psychometric validation on QOL questionnaires among patients at various stages of disease trajectory, and the paucity of studies examining utility and cost-effectiveness. Further research is needed to address these knowledge gaps so QOL questionnaires can be better used to inform clinical practice and research.

Does the EQ-5D capture the concerns measured by the Palliative care Outcome Scale? Mapping the Palliative care Outcome Scale onto the EQ-5D using statistical methods

BACKGROUND

The main measure to generate utility data for economic evaluations is the EQ-5D, but no study has tested whether or how to map from palliative care measures to the EQ-5D.

AIMS

To assess the level of conceptual overlap between palliative outcomes and the EQ-5D, and the feasibility of mapping between them to obtain utilities for the Palliative care Outcome Scale.

DESIGN

A cross-sectional secondary analysis of data from three studies.

SETTING/PARTICIPANTS

Patients receiving palliative care and bereaved relatives, recruited from three tertiary National Health Service hospitals in South London.

METHODS

The overlap between both measures was assessed using principal component analysis. The Palliative care Outcome Scale was mapped onto the EQ-5D using three regression models.

RESULTS

Spearman's correlations between both instruments were low (mean rho = 0.11). The principal component analysis showed the Palliative care Outcome Scale is associated with only two EQ-5D dimensions (pain; and anxiety/depression). No Palliative care Outcome Scale items loaded onto the mobility, self-care and usual activities dimensions of the EQ-5D. The mapping models performed poorly at predicting utilities from Palliative care Outcome Scale data (mean absolute error >0.3 and R² <0.10). Hence, none of the models can be recommended as acceptable for calculating utilities from Palliative care Outcome Scale responses.

CONCLUSION

Differences between the Palliative care Outcome Scale and the EQ-5D do not undermine the qualities of either instrument when used for their own purposes. However, due to conceptual differences, the EQ-5D does not capture some of the concerns measured by the Palliative care Outcome Scale, and therefore, mapping onto the EQ-5D is unlikely to provide an appropriate basis for estimating utilities for conducting economic evaluations in palliative care studies.

Measuring the quality of life of people at the end of life: The McGill Quality of Life Questionnaire-Revised

BACKGROUND

The McGill Quality of Life Questionnaire has been widely used with people with life-threatening illnesses without modification since its publication in 1996. With use, areas for improvement have emerged; therefore, various minor modifications were tested over time.

AIM

To revise the McGill Quality of Life Questionnaire (McGill Quality of Life Questionnaire-Revised) while maintaining or improving its psychometric properties and length, keeping it as close as possible to the McGill Quality of Life Questionnaire to enable reasonable comparison with existing McGill Quality of Life Questionnaire literature.

DESIGN

Data sets from eight studies were used (four studies originally used to develop the McGill Quality of Life Questionnaire, two to develop new McGill Quality of Life Questionnaire versions, and two with unrelated purposes). The McGill Quality of Life Questionnaire-Revised was developed using analyses of measurement invariance, confirmatory factor analysis, and calculation of correlations with the McGill Quality of Life Questionnaire's global quality of life item.

SETTING/PARTICIPANTS

Data were from 1702 people with life-threatening illnesses recruited from acute and palliative care units, palliative home care services, and oncology and HIV/AIDS outpatient clinics.

RESULTS

The McGill Quality of Life Questionnaire-Revised consists of 14 items (plus the global quality of life item). A new Physical subscale was created combining physical symptoms and physical well-being and a new item on physical functioning. The Existential subscale was reduced to four items. The revised Support subscale, renamed Social, focuses more on relationships. The Psychological subscale remains unchanged. Confirmatory factor analysis results provide support for the measurement structure of the McGill Quality of Life Questionnaire-Revised. The overall scale has good internal consistency reliability ( α = 0.94).

CONCLUSION

The McGill Quality of Life Questionnaire-Revised improves on and can replace the McGill Quality of Life Questionnaire since it contains improved wording, a somewhat expanded repertoire of concepts with fewer items, and a single subscale for the physical domain, while retaining good psychometric properties.

Measurement of Quality of Life in Palliative Care: Evidence for Criterion-Oriented Validity of a Single-Item Approach

BACKGROUND

Assessment of quality of life is of central importance in palliative care to understand patients' needs and improve their treatment. However, due to the severely compromised state of health of the severely ill or dying patients, the possibility of an adequate assessment with longer questionnaires is limited.

OBJECTIVE

Investigation of the criterion-oriented validity of a single item to measure quality of life in palliative care patients.

DESIGN

In a cross-sectional study, correlations of the single item with established questionnaires were analyzed.

PARTICIPANTS/SETTING

At Malteser Hospital Bonn and Bonn University Hospital, 72 palliative patients, mainly suffering from cancer, were investigated.

MEASUREMENTS

Clinical symptoms were measured by the Minimal Documentation System (MIDOS) and quality of life was assessed by the single item "How satisfied are you currently with your physical and emotional well-being?" on a 7-point scale as well as by the Functional Assessment of Cancer Therapy-General (FACT-G) and the Palliative Outcome Scale (POS).

RESULTS

Seventy-one of 72 patients filled in the single item and the POS, 64 patients the FACT-G. There was a high correlation between the assessment of quality of life by the single item and the FACT-G (r = 0.695, p < 0.01) as well as the POS (r = -0.630, p < 0.01).

CONCLUSIONS

The study confirms the criterion-oriented validity of the single item to measure quality of life in palliative care patients. This can be seen as a first step to validate this economic instrument. Future studies should focus on the analysis of further psychometric aspects (e.g., reliability, sensitivity to change) of the single item.

Spanish modified version of the palliative care outcome scale-symptoms renal: cross-cultural adaptation and validation

BACKGROUND

Patients with chronic kidney disease (CKD) have a high symptoms burden that is related to a poor health-related quality of life (HRQoL) and high costs of care. Validated instruments may be useful for assessing the symptoms and monitoring outcomes in these patients. The Palliative care Outcome Scale-Symptoms Renal (POS-S Renal) is a patient-reported outcome measure for assessing symptoms in CKD stage 4-5. This study is the first cross-cultural adaptation and psychometric analysis of this clinical tool. The purpose of this study is to carry out a cross-cultural adaptation of the POS-S Renal for Spanish-speaking patients, and to perform an analysis of the psychometric properties of this questionnaire.

METHODS

The English version of the POS-S Renal was culturally adapted and translated into Spanish using a double forward and backward method. An expert panel evaluated the content validity. The questionnaire was pilot-tested in 30 patients. A total of 200 patients with CKD stage 4-5 filled in a modified Spanish version of the POS-S Renal and the MSAS-SF. Statistical analysis to evaluate the psychometric properties of the questionnaire was carried out.

RESULTS

The content validity index (CVI) was 0.97, which indicated that the content of the instrument is an adequate reflection of the symptoms in advanced CKD (ACKD). The factor analysis indicated a two-factor solution explaining 35.05% of total variance. The confirmatory factor analysis (CFA) demonstrated that the two factor model was well supported (comparative fit index = 0.98, root mean square error of approximation = 0.068). This assessment tool demonstrated a satisfactory test-retest reliability (r = 0.909 to factor 1, r = 0.695 to factor 2, r = 0.887 to total score), good internal consistency to factor 1 (α = 0.78) and moderate internal consistency to factor 2 (α = 0.56). Concurrent criterion-related validity with MSAS-SF was also demonstrated, with r = 0.860, which indicated a high degree of correlation with a validated instrument that has been used in patients with ACKD.

CONCLUSIONS

The Spanish modified version of the POS-S Renal is a reliable and valid instrument that can be used to assess symptoms in Spanish patients with CKD stage 4-5.

Psychometric Properties of a Generic, Patient-Centred Palliative Care Outcome Measure of Symptom Burden for People with Progressive Long Term Neurological Conditions

BACKGROUND

There is no standard palliative care outcome measure for people with progressive long term neurological conditions (LTNC). This study aims to determine the psychometric properties of a new 8-item palliative care outcome scale of symptom burden (IPOS Neuro-S8) in this population.

DATA AND METHODS

Data were merged from a Phase II palliative care intervention study in multiple sclerosis (MS) and a longitudinal observational study in idiopathic Parkinson's disease (IPD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). The IPOS Neuro-S8 was assessed for its data quality, score distribution, ceiling and floor effects, reliability, factor structure, convergent and discriminant validity, concurrent validity with generic (Palliative care Outcome Scale) and condition specific measures (Multiple Sclerosis Impact Scale; Non-motor Symptoms Questionnaire; Parkinson's Disease Questionnaire), responsiveness and minimally clinically important difference.

RESULTS

Of the 134 participants, MS patients had a mean Extended Disability Status Scale score 7.8 (SD = 1.0), patients with an IPD, MSA or PSP were in Hoehn & Yahr stage 3-5. The IPOS Neuro-S8 had high data quality (2% missing), mean score 8 (SD = 5; range 0-32), no ceiling effects, borderline floor effects, good internal consistency (Cronbach's α = 0.7) and moderate test-retest reliability (intraclass coefficient = 0.6). The results supported a moderately correlated two-factor structure (Pearson's r = 0.5). It was moderately correlated with generic and condition specific measures (Pearson's r: 0.5-0.6). There was some evidence for discriminant validity in IPD, MSA and PSP (p = 0.020), and for good responsiveness and longitudinal construct validity.

CONCLUSIONS

IPOS Neuro-S8 shows acceptable to promising psychometric properties in common forms of progressive LTNCs. Future work needs to confirm these findings with larger samples and its usefulness in wider disease groups.

The Palliative Outcome Scale (POS) applied to clinical practice and research: an integrative review

Objective:

to identify and evaluate the evidence found in the international scientific literature on the application of the Palliative Outcome Scale (POS) in clinical practice and research in Palliative Care (PC).

Method:

integrative literature review, through the search of publications in journals indexed in PubMed / MEDLINE, LILACS, SciELO and CINAHL databases, between the years 1999 and 2014.

Results:

the final sample consisted of 11 articles. In the data analysis, the articles were classified into 2 units of analysis (studies using the POS as a resource in research and studies using the POS in clinical practice), in which the information was presented in the form of sub-themes related to publications of the selected studies, highlighting the synthesis of the results.

Conclusion:

POS emerged as an important tool for measuring outcomes to assess the quality of life of patients and families, of the quality of care provided and the PC service organization. The international scientific literature on the application of POS proved to be relevant to the advancement and consolidation of the field of knowledge related to PC.

Screening for depression in advanced disease: psychometric properties, sensitivity, and specificity of two items of the Palliative Care Outcome Scale (POS)

CONTEXT

Depression is common among patients with advanced disease but often difficult to detect.

OBJECTIVES

To assess the Palliative care Outcome Scale (POS) (10 items) against the Geriatric Depression Scale (GDS)-10 total score and the Hospital Anxiety and Depression Scale (HADS)-Depression subscale total score and determine if the POS has appropriate items to screen for depression among people with advanced disease.

METHODS

This was a secondary analysis performed on five studies. Four psychometric properties were assessed: data quality, scaling assumptions, acceptability, and internal consistency (reliability). Receiver operating characteristic (ROC) curves were used to determine the area under the curve. Sensitivity, specificity, positive and negative predictive values, false positive and negative rates, and positive and negative likelihood ratios were computed.

RESULTS

The overall sample had 416 patients from Germany and England: 144 had cancer and 267 had nonmalignant conditions. Prevalence of depression across the sample was 17.5%. Floor and ceiling effects were rare. Cronbach's alpha coefficients for POS items 7 and 8 summed, GDS-10 and HADS-Depression items varied: 0.61 (heart failure) and 0.80 (cancer). Two items combined (Item 7-feeling depressed and Item 8-feeling good about yourself) consistently presented the highest area under the ROC curve, ranging from 0.76 (95% CI 0.60, 0.93) (Germany, lung cancer) to 0.97 (95% CI 0.91, 1.0) (heart failure), highest negative predictive value, and lowest false negative rate. For the overall sample, the cutoff 2/3 presented a negative predictive value of 89.4% (95% CI 84.7, 92.8) and false negative rate of 10.6 (95% CI 7.2, 15.3).

CONCLUSION

POS items 7 and 8 summed are potentially useful to screen for depression in advanced disease populations.

Reliability and validity of the Menopausal Symptom Scale

Menopausal symptom experiences differ by racial/ethnic group. Thus, health care professionals who use instruments to measure menopausal symptoms need to be aware of cultural sensitivities. The purpose of this study was to examine the psychometric properties of the Menopausal Symptom Scale among Korean women. Data from 229 Korean women between the ages of 40 and 65 years, selected by convenience sampling, were collected during 2010-2011. Psychometric properties were evaluated through content validity and item analysis, construct validity, discriminant validity, criterion-related validity, floor/ceiling effects, and internal consistency reliability. Exploratory and confirmatory factor analyses revealed four factors explaining 65% of variance in the items. Discriminant validity and the criterion-related validity were supported. No significant floor/ceiling effects were found. Cronbach's alpha values ranged from 0.90 to 0.95. The Menopausal Symptom Scale developed for Korean menopausal women appeared to be a valid and reliable instrument. It appeared that it measured psychological symptoms more comprehensively and in a culturally-specific or ethnic-specific manner in menopausal women of Asian or traditional cultures. It will be necessary to broaden the scale of research to other ethnic groups and countries to verify the psychometric properties specific to the ethnic group or country.

Informed palliative care in nursing homes through the interRAI Palliative Care instrument: a study protocol based on the Medical Research Council framework

BACKGROUND

Nursing homes are important locations for palliative care. Through comprehensive geriatric assessments (CGAs), evaluations can be made of palliative care needs of nursing home residents. The interRAI Palliative Care instrument (interRAI PC) is a CGA that evaluates diverse palliative care needs of adults in all healthcare settings. The evaluation results in Client Assessment Protocols (CAPs: indications of problems that need addressing) and Scales (e.g. Palliative Index for Mortality (PIM)) which can be used to design, evaluate and adjust care plans. This study aims to examine the effect of using the interRAI PC on the quality of palliative care in nursing homes. Additionally, it aims to evaluate the feasibility and validity of the interRAI PC.

METHODS

This study covers phases 0, I and II of the Medical Research Council (MRC) framework for designing and evaluating complex interventions, with a longitudinal, quasi-experimental pretest-posttest design and with mixed methods of evaluation. In phase 0, a systematic literature search is conducted. In phase I, the interRAI PC is adapted for use in Belgium and implemented on the BelRAI-website and a practical training is developed. In phase II, the intervention is tested in fifteen nursing homes. Participating nursing homes fill out the interRAI PC during one year for all residents receiving palliative care. Using a pretest-posttest design with quasi-random assignment to the intervention or control group, the effect of the interRAI PC on the quality of palliative care is evaluated with the Palliative care Outcome Scale (POS). Psychometric analysis is conducted to evaluate the predictive validity of the PIM and the convergent validity of the CAP 'Mood' of the interRAI PC. Qualitative data regarding the usability and face validity of the instrument are collected through focus groups, interviews and field notes.

DISCUSSION

This is the first study to evaluate the validity and effect of the interRAI PC in nursing homes, following a methodology based on the MRC framework. This approach improves the study design and implementation and will contribute to a higher generalizability of results. The final result will be a psychometrically evaluated CGA for nursing home residents receiving palliative care.

A psychometric validation of two brief measures to assess palliative need in patients severely affected by multiple sclerosis

CONTEXT

Most patient-reported outcome measurement tools in multiple sclerosis (MS) are geared toward less severely affected patients. Palliative care outcome measures have not been validated in patients with MS.

OBJECTIVES

To assess the psychometric properties of the Core-Palliative Care Outcome Scale (Core-POS) and POS-MS-Symptoms (POS-MS-S) in patients severely affected by MS.

METHODS

Secondary analyses were conducted on data from a Phase II trial of palliative care in MS. Patients completed assessments using the following five scales: Core-POS, POS-MS-S, the Multiple Sclerosis Impact Scale, the United Kingdom Neurological Disability Scale, and the Expanded Disability Status Scale. Data quality, scaling assumptions, acceptability, internal consistency, and construct validity of the Core-POS and POS-MS-S were determined using standard psychometric methods.

RESULTS

The 46 participants had a mean ±SD age of 52.8 ±10.6 years. The mean Expanded Disability Status Scale score was 7.9 ± 1.2. Missing data were low (0 and 0.2% for the Core-POS and POS-MS-S, respectively), and floor and ceiling effects were absent. Internal consistency was good (Cronbach's alpha for the Core-POS and POS-MS-S were 0.72 [95% CI 0.56-0.84] and 0.81 [95% CI 0.72-0.89], respectively). Construct validity was consistent with a priori hypotheses 17 of 20 times.

CONCLUSION

Psychometric analyses confirm that the Core-POS and POS-MS-S are acceptable, reliable, and valid in patients severely affected by MS.

Living with breathlessness: a survey of caregivers of breathless patients with lung cancer or heart failure

BACKGROUND

Breathlessness is a common, distressing symptom in patients with advanced disease. With increasing focus on home death for patients, carers are expected to support breathless people at home. Little is known about how carers experience breathlessness and the differences in caring for someone with breathlessness and malignant or non-malignant disease.

AIM

To compare experiences of caring for a breathless patient with lung cancer versus those with heart failure and to examine factors associated with caregiver burden and positive caring experiences.

DESIGN

Cross-sectional survey of caregivers of breathless patients.

SETTING/PARTICIPANTS

Participants were recruited from two London hospitals.

INCLUSION CRITERIA

caregivers of patients with breathlessness and heart failure or lung cancer. Measures included self-completion of Short Form version of Zarit Burden Interview, a 'positive caring experiences' scale and Palliative Care Outcome Scale. We compared caregiver reports between heart failure and lung cancer. Multiple regression analyses were used to examine factors related to burden and positive caring experiences.

RESULTS

In total, 51 heart failure and 50 lung cancer caregivers were recruited. Most were spouses (72%) and women (80%). Severity of patient breathlessness was similar in both groups. Caregiver concerns were mostly similar across conditions. Higher burden was associated with poorer 'quality of patient care' and worse carer psychological health (R (2) = 0.37, F = 12.2, p = 0.01). Caregiver depression and looking after more breathless patients were associated with fewer positive caring experiences (R (2) = 0.15, F = 4.4, p = 0.04).

CONCLUSIONS

Those who care for breathless patients report high levels of unmet needs and burden, equally severe for heart failure and lung cancer caregivers. Caregivers of patients with more severe breathlessness report fewer positive caring experiences and should be targeted by services with increased support in managing this symptom.

Reliability and concurrent validity of the Palliative Outcome Scale, the Rotterdam Symptom Checklist, and the Brief Pain Inventory

BACKGROUND

Some domains of the questionnaires used to measure symptoms and quality of life (QOL) in patients with advanced cancer seem to measure similar dimensions or constructs, so it would be useful for clinicians to demonstrate the interchangeability of equivalent domains of the questionnaires in measuring the same constructs.

OBJECTIVE

This study investigated the reliability and concurrent validity of the Palliative Outcome Scale (POS), the Rotterdam Symptom Checklist (RSCL), and the Brief Pain Inventory (BPI), used to measure symptom control in patients with advanced cancer.

DESIGN

This was an evaluative study.

SETTING/SUBJECTS

Subjects were patients with advanced cancer attended by Spanish primary care physicians.

MEASUREMENTS

Secondary analysis was performed of 117 outpatients who completed the POS, BPI, and RSCL at two different times, with an interval of 7 to 10 days. Bland and Altman analyses and plot, repeatability coefficient, as well as Spearman correlations were carried out.

RESULTS

There were 117 included patients. Mean age was 69.4 (11.5) years, gender was 60% male, 37.6% completed only elementary school, diagnoses were mainly digestive and lung cancer, with a low functional rate and presence of oncologic pain. First and second questionnaire rounds showed significant correlations and agreement. Agreement was shown between pain intensity of BPI and pain and physical scales of RSCL, and between physical symptoms of RSCL and of POS, with significant correlations in equivalent dimensions.

CONCLUSION

BPI, POS, and RSCL have shown adequate reliability and moderate concurrent validity among them.

Cognitive interviewing of bereaved relatives to improve the measurement of health outcomes and care utilisation at the end of life in a mortality followback survey

PURPOSE

The evaluation of end of life care via bereaved relatives is increasingly common. We aimed to improve the measurement of health outcomes and care utilisation at the end of life with this population.

METHODS

A cross-sectional study of 20 bereaved relatives of cancer patients was conducted. In phase I, nine underwent a cognitive interview for 65-150 min using five measures: Client Service Receipt Inventory, Life Before Death survey care satisfaction items, Palliative care Outcome Scale (POS), EQ-5D and Core Bereavement Items (CBI). In phase II, items/scales were revised and tested with a further 11 participants. Content analysis explored information processing and errors.

RESULTS

All 20 participants understood most questions despite finding them demanding and intense. Judging the accuracy of information and formulating final answers posed more difficulties than recalling facts. Uncertainty and missing data on care utilisation were often due to estimating averages; consequently categories were introduced. Participants perceived the care satisfaction rating scale to be positively biased; a very poor category was added. POS was seen to ask relevant but sometimes difficult questions, whilst the EQ-5D produced fewer missing data but lacked intermediate categories. CBI had terms that participants felt were unfamiliar, unrealistic, unclear or too strong; hence, we changed to the Texas Revised Inventory of Grief (with no problems identified).

CONCLUSIONS

Cognitive interviewing helped select measures and make changes that improved the measurement of health outcomes and care utilisation at the end of life with bereaved relatives. The use of both generic and specific health measures and cost measurement in bereavement is encouraged.

How to analyze palliative care outcome data for patients in Sub-Saharan Africa: an international, multicenter, factor analytic examination of the APCA African POS

CONTEXT

The incidence of life-limiting progressive disease in sub-Saharan Africa presents a significant clinical and public health challenge. The ability to easily measure patient outcomes is essential to improving care.

OBJECTIVES

The present study aims to determine the specific factors (if any) that underpin the African Palliative Care Association African Palliative Outcome Scale to assist the analysis of data in routine clinical care and audit.

METHODS

Using self-reported data collected from patients with HIV infection in eastern and southern Africa, an exploratory factor analysis was undertaken with 1337 patients; subsequently, a confirmatory analysis was done on two samples from separate data sets (n = 445).

RESULTS

Using exploratory factor analysis initially, both two- and three-factor solutions were examined and found to meet the criteria for simple structure and be readily interpretable. Then using confirmatory factor analysis on two separate samples, the three-factor solution demonstrated better fit, with Goodness-of-Fit Index values greater than 0.95 and Normative Fit Index values close to 0.90. The resulting three factors were 1) physical and psychological well-being, 2) interpersonal well-being, and 3) existential well-being.

CONCLUSION

This analysis presents an important new opportunity in the analysis of outcome data for patients with progressive disease. It has advantages over both the total scoring of multidimensional scaling (which masks differences between domains) and of item scoring (which requires repeated analyses). The three factors map well onto the underlying concept and clinical goals of palliative care, and will enable audit of facility care.

Proxy assessment of patients before and after radiotherapy for brain metastases. Results of a prospective study using the DEGRO brain module

PURPOSE

Proxies of patients with poor performance status could give useful information about the patients' quality of life (QoL). We applied a newly developed questionnaire in a prospective QoL study of patients undergoing radiotherapy for brain metastases in order to make the first move to validate this instrument, and we compared the results with scores obtained using validated patient-completed instruments.

MATERIALS AND METHODS

From January 2007 to June 2010,  166 patients with previously untreated brain metastases were recruited at 14 centers in Germany and Austria. The EORTC-QLQ-C15-PAL and the brain module BN20 were used to assess QoL in patients at the start of treatment and 3 months later. At the same time points, 141 of their proxies estimated the QoL with the new DEGRO brain module (DBM), a ten-item questionnaire rating the general condition as well as functions and impairment by symptoms in areas relevant to patients with brain metastases.

RESULTS

At 3 months, 85 of 141 patients (60%) with initial response by a proxy were alive. Sixty-seven of these patients (79% of 3-month survivors) and 65 proxies completed the second set of questionnaires. After 3 months, QoL significantly deteriorated in all items of proxy-assessed QoL except headache. Correlations between self-assessed and proxy-assessed QoL were high in single items such as nausea, headache, and fatigue.

CONCLUSIONS

The high correlation between self-assessment and proxy ratings as well as a similar change over time for both approaches suggest that in patients with brain metastases, proxy assessment using the DBM questionnaire can be an alternative approach to obtaining QoL data when patients are unable to complete questionnaires themselves. Our self-constructed and first applied DBM is the only highly specific instrument for patients with brain metastases, but further tests are needed for its final validation.

Symptoms and quality of life in late stage Parkinson syndromes: a longitudinal community study of predictive factors

BACKGROUND

Palliative care is increasingly offered earlier in the cancer trajectory but rarely in Idiopathic Parkinson's Disease(IPD), Progressive Supranuclear Palsy(PSP) or Multiple System Atrophy(MSA). There is little longitudinal data of people with late stage disease to understand levels of need. We aimed to determine how symptoms and quality of life of these patients change over time; and what demographic and clinical factors predicted changes.

METHODS

We recruited 82 patients into a longitudinal study, consenting patients with a diagnosis of IPD, MSA or PSP, stages 3-5 Hoehn and Yahr(H&Y). At baseline and then on up to 3 occasions over one year, we collected self-reported demographic, clinical, symptom, palliative and quality of life data, using Parkinson's specific and generic validated scales, including the Palliative care Outcome Scale (POS). We tested for predictors using multivariable analysis, adjusting for confounders.

FINDINGS

Over two thirds of patients had severe disability, over one third being wheelchair-bound/bedridden. Symptoms were highly prevalent in all conditions - mean (SD) of 10.6(4.0) symptoms. More than 50% of the MSA and PSP patients died over the year. Over the year, half of the patients showed either an upward (worsening, 24/60) or fluctuant (8/60) trajectory for POS and symptoms. The strongest predictors of higher levels of symptoms at the end of follow-up were initial scores on POS (AOR 1.30; 95%CI:1.05-1.60) and being male (AOR 5.18; 95% CI 1.17 to 22.92), both were more predictive than initial H&Y scores.

INTERPRETATION

The findings point to profound and complex mix of non-motor and motor symptoms in patients with late stage IPD, MSA and PSP. Symptoms are not resolved and half of the patients deteriorate. Palliative problems are predictive of future symptoms, suggesting that an early palliative assessment might help screen for those in need of earlier intervention.

Palliative patients cared for at home by PAMINO-trained and other GPs - health-related quality of life as measured by QLQ-C15-PAL and POS

Background

To maintain patients’ quality of life is one of the major goals in palliative home care provided by general practitioners (GPs). GPs need adequate training to care for palliative patients. The paper seeks to evaluate whether a specific training in Germany (PAMINO) has any improving impact on the care of palliative patients and their health-related quality of life.

Methods

From September 2007 until June 2009, GPs and their palliative care patients with cancer participated in a study to evaluate palliative courses for GPs offered by a regional palliative care initiative (PAMINO). For a period of six months at most or until death, patients were asked monthly to judge their quality of life on the Quality of Life Questionnaire Core 15 Palliative (QLQ-C15-PAL) of the European Organization for Research and Treatment of Cancer (EORTC) and on the Palliative Care Outcome Scale (POS). The ‘Overall quality of life’ scale of the QLQ-C15-PAL takes values between 0 and 100 with higher values indicating a higher quality of life. The POS sum scale takes values between 0 and 40 with higher values indicating worse care outcomes. Patients cared for by PAMINO-trained GPs and patients cared for by other GPs (control group) are compared using t-tests for differences in group means.

Results

One hundred patients participated in the study; 96 patients filled out the questionnaires at least once. On the QLQ-C15-PAL, mean quality of life of the patient groups of PAMINO-trained and other GPs were 37.7 (SD = 25.5) and 39.4 (SD = 26.3) (p = .76), respectively. On the POS, respective mean values of 13.6 (SD = 5.8) and 12.0 (SD = 6.5) (p = .26) were given. Patients cared for by a PAMINO-trained GP did not report better quality of life and care outcomes than patients cared for by other general practitioners.

Conclusions

Patients cared for by PAMINO-trained and other GPs in our study did not report differences in quality of life. Quality of life and care outcomes of all patients were better than of palliative patients in institutional or specialized care, emphasizing the ability of GPs to provide adequate care for these vulnerable patients. However, conclusions need to be drawn cautiously since the study had a small sample size.

Measuring the quality of dying and quality of care when dying in long-term care settings: a qualitative content analysis of available instruments

CONTEXT

Long-term care (LTC) settings have become a significant site for end-of-life care; consequently, instruments that assess the quality of dying and care may be useful in these settings.

OBJECTIVES

To evaluate the content of available measurement instruments to assess the quality of dying and care when dying.

METHODS

Qualitative content analysis to categorize items as structure of care, process of care, satisfaction with health care (the first three representing quality of care and its evaluation), quality of dying, or patient factors.

RESULTS

Instruments that measure mostly quality of care and its evaluation are the Family Perception of Physician-Family Caregiver Communication, End-of-Life in Dementia (EOLD) Satisfaction With Care, Family Perception of Care Scale, Toolkit of Instruments to Measure End-of-Life Care after-death bereaved family member interview (nursing home version), and the Family Assessment of Treatment at the End-of-Life Short version. Instruments measuring quality of dying are the EOLD-Comfort Assessment in Dying, EOLD-Symptom Management, Mini-Suffering State Examination, and Palliative Care Outcome Scale. The Quality of Dying in Long-Term Care measures care and dying. The Minimum Data Set-Palliative Care measures mostly dying and patient factors. The instruments differ in dementia specificity, time of administration, and respondent.

CONCLUSION

Instruments that assess quality when dying differ in several ways and most do not measure a single construct, which is relevant to guiding and evaluating care. Comparing psychometric properties and usefulness of instruments that measure similar constructs is the next step in determining which are best suited for use in LTC.

A psychometric evaluation of measures of spirituality validated in culturally diverse palliative care populations

CONTEXT

Despite the need to accurately measure spiritual outcomes in diverse palliative care populations, little attention has been paid to the properties of the tools currently in use.

OBJECTIVES

This systematic review aimed to appraise the psychometric properties, multifaith appropriateness, and completion time of spiritual outcome measures validated in multicultural advanced cancer, HIV, or palliative care populations.

METHODS

Eight databases were searched to identify relevant validation and research studies. A comprehensive search strategy included search terms in three categories: palliative care, spirituality, and outcome measurement. Inclusion criteria were: validated in advanced cancer, HIV, or palliative care populations and in an ethnically diverse context. Included tools were evaluated with respect to psychometric properties (validity, reproducibility, responsiveness, and interpretability), multifaith appropriateness, and time to complete.

RESULTS

A total of 191 articles were identified, yielding 85 tools. Twenty-six tools (representing four families of measures and five individual tools) met the inclusion criteria. Twenty-four tools demonstrated good content validity and 12 demonstrated adequate internal consistency. Only eight tools demonstrated adequate construct validity, usually because specific hypotheses were not stated and tested. Seven tools demonstrated adequate test-retest reliability; two tools showed adequate responsiveness, and two met the interpretability criterion. Data on the religious faith of the population of validation were available for 11 tools; of these, eight were tested in multifaith populations.

CONCLUSION

Results suggest that, at present, the McGill Quality of Life Questionnaire, the Measuring the Quality of Life of Seriously Ill Patients Questionnaire, and the Palliative Outcome Scale are the most appropriate multidimensional measures containing spiritual items for use in multicultural palliative care populations. However, none of these measures score perfectly on all psychometric criteria, and their multifaith appropriateness requires further testing.

Predictors of Quality of Life in Elderly Hospice Patients with Cancer

PURPOSE: While quality of life is the focus of care in hospices, limited research has been conducted on the quality of life of cancer patients in hospice home care. The purpose of this study was to explore the predictors of quality of life of older adults who are receiving hospice care in their homes. METHODS: A secondary analysis of data from a larger study was conducted using linear regression and including the following predictor variables: age, functional status, number of symptoms endorsed, overall symptom distress, pain intensity, and depressive symptoms. The outcome variable was quality of life. RESULTS: The sample consisted of 533 adults with an average age of 78.1 years (SD=7.4). A regression model that included symptom distress, number of symptoms, depression, and functional status accounted for 46% of the variance in quality of life. Pain, age, and caregiver depression did not contribute to predicting quality of life and therefore were not included in the final model. CONCLUSIONS AND IMPLICATIONS: Because both physical symptoms and depression are predictors of quality of life, a continued focus is needed on these factors by those providing care to older adults with cancer near the end of life.

Psychometric properties of instruments to measure the quality of end-of-life care and dying for long-term care residents with dementia

Purpose

Quality of care for long-term care (LTC) residents with dementia at the end-of-life is often evaluated using standardized instruments that were not developed for or thoroughly tested in this population. Given the importance of using appropriate instruments to evaluate the quality of care (QOC) and quality of dying (QOD) in LTC, we compared the validity and reliability of ten available instruments commonly used for these purposes.

Methods

We performed prospective observations and retrospective interviews and surveys of family (n = 70) and professionals (n = 103) of LTC decedents with dementia in the Netherlands.

Results

Instruments within the constructs QOC and QOD were highly correlated, and showed moderate to high correlation with overall assessments of QOC and QOD. Prospective and retrospective ratings using the same instruments differed little. Concordance between family and professional scores was low. Cronbach’s alpha was mostly adequate. The EOLD–CAD showed good fit with pre-assumed factor structures. The EOLD–SWC and FPCS appear most valid and reliable for measuring QOC, and the EOLD–CAD and MSSE for measuring QOD. The POS performed worst in this population.

Conclusions

Our comparative study of psychometric properties of instruments allows for informed selection of QOC and QOD measures for LTC residents with dementia.

The use of two common palliative outcome measures in clinical care and research: a systematic review of POS and STAS

The Palliative Care Outcome Scale (POS) and the Support Team Assessment Schedule (STAS) are outcome measures assessing quality of care in palliative care patients. This review aims to appraise their use in clinical care and research. Five electronic databases were searched (February 2010) for original papers describing the validation or use of POS and/or STAS. Of the 83 papers included, 43 studies were on POS, 39 on STAS and one study using both. Eight STAS studies validated the original version, four an adaptation; 20 studies applied the STAS in another culture and 19 in other languages. POS papers reported included: 14 adapted POS versions, 12 translations of the POS and 15 studies of use in different cultures. Both measures have been used in cancer, HIV/AIDS and in mixed groups. POS has also been applied in neurological, kidney, pulmonary and heart disease. Both tools were used in different areas such as the evaluation of care or interventions, description of symptom prevalence and implementation of outcome measures in clinical practice. Overall, they seem to be well accepted tools for outcome measurement in palliative care, both in clinical care and research.

Expert opinion on detecting and treating depression in palliative care: A Delphi study

BACKGROUND

There is a dearth of data regarding the optimal method of detecting and treating depression in palliative care. This study applied the Delphi method to evaluate expert opinion on choice of screening tool, choice of antidepressant and choice of psychological therapy. The aim was to inform the development of best practice recommendations for the European Palliative Care Research Collaborative clinical practice guideline on managing depression in palliative care.

METHODS

18 members of an international, multi-professional expert group completed a structured questionnaire in two rounds, rating their agreement with proposed items on a scale from 0-10 and annotating with additional comments. The median and range were calculated to give a statistical average of the experts' ratings.

RESULTS

There was contention regarding the benefits of screening, with 'routine informal asking' (median 8.5 (0-10)) rated more highly than formal screening tools such as the Hospital Anxiety and Depression Scale (median 7.0 (1-10). Mirtazapine (median 9 (7-10) and citalopram (median 9 (5-10) were the considered the best choice of antidepressant and cognitive behavioural therapy (median 9.0 (3-10) the best choice of psychological therapy.

CONCLUSIONS

The range of expert ratings was broad, indicating discordance in the views of experts. Direct comparative data from randomised controlled trials are needed to strengthen the evidence-base and achieve clarity on how best to detect and treat depression in this setting.

The measurement of spirituality in palliative care and the content of tools validated cross-culturally: a systematic review

CONTEXT

Despite the need to assess spiritual outcomes in palliative care, little is known about the properties of the tools currently used to do so. In addition, measures of spirituality have been criticized in the literature for cultural bias, and it is unclear which tools have been validated cross-culturally.

OBJECTIVES

This systematic review aimed to identify and categorize spiritual outcome measures validated in advanced cancer, human immunodeficiency virus (HIV), or palliative care populations; to assess the tools' cross-cultural applicability; and for those measures validated cross-culturally, to determine and categorize the concepts used to measure spirituality.

METHODS

Eight databases were searched to identify relevant validation and research studies. An extensive search strategy included search terms in three categories: palliative care, spirituality, and outcome measurement. Tools were evaluated according to two criteria: 1) validation in advanced cancer, HIV, or palliative care and 2) validation in an ethnically diverse context. Tools that met Criterion 1 were categorized by type; tools that also met Criterion 2 were subjected to content analysis to identify and categorize the spiritual concepts they use.

RESULTS

One hundred ninety-one articles were identified, yielding 85 tools. Fifty different tools had been reported in research studies; however, 30 of these had not been validated in palliative care populations. Thirty-eight tools met Criterion 1: general multidimensional measures (n=21), functional measures (n=11), and substantive measures (n=6). Nine measures met Criterion 2; these used spiritual concepts relating to six themes: Beliefs, practices, and experiences; Relationships; Spiritual resources; Outlook on life/self; Outlook on death/dying; and Indicators of spiritual well-being. A conceptual model of spirituality is presented on the basis of the content analysis. Recommendations include consideration of both the clinical and cultural population in which spiritual instruments have been validated when selecting an appropriate measure for research purposes. Areas in need of further research are identified.

CONCLUSION

The nine tools identified in this review are those that have currently been validated in cross-cultural palliative care populations and, subject to appraisal of their psychometric properties, may be suitable for cross-cultural research.
