Development of a patient-reported palliative care-specific health classification system: the POS-E

BackgroundGeneric preference-based measures are commonly used to estimate quality-adjusted life-years (QALYs) to inform resource-allocation decisions. However, concerns have been raised that generic measures may be inappropriate in palliative care.ObjectiveOur objective was to derive a health-state classification system that is amenable to valuation from the ten-item Palliative Care Outcome Scale (POS), a widely used patient-reported outcome measure in palliative care.MethodsThe dimensional structure of the original POS was assessed using factor analysis. Item performance was assessed, using Rasch analysis and psychometric criteria, to enable the selection of items that represent the dimensions covered by the POS. Data from six studies of patients receiving palliative care were combined (N = 1011) and randomly split into two halves for development and validation. Analysis was undertaken on the development data, and results were validated by repeating the analysis with the validation dataset.ResultsFollowing Rasch and factor analyses, a classification system of seven items was derived. Each item had two to three levels. Rasch threshold map helped identify a set of 14 plausible health states that can be used for the valuation of the instrument to derive a preference-based index.ConclusionCombining factor analysis and Rasch analysis with psychometric criteria provides a valid method of constructing a classification system for a palliative care-specific preference-based measure. The next stage is to obtain preference weights so the measure can be used in economic evaluations in palliative care

Systematic review of pharmacological therapies for the management of ischaemic pain in patients with non-reconstructable critical limb ischaemia

Background Critical limb ischaemia (CLI) is a severe manifestation of peripheral arterial disease, characterised by chronic ischaemic rest pain, ulcers or gangrene. Management of ischaemic pain is challenging in patients with no options for revascularisation and optimal pharmacological therapies have not been established.Objectives To identify and evaluate the effectiveness of pharmacological therapies to treat ischaemic pain secondary to non-reconstructable CLI.Methods This systematic review was reported in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. Comprehensive searches of three electronic databases, a PubMed-related articles link search, grey literature search and hand-searches of the bibliographies of relevant papers and textbooks were performed. Studies recruiting adult patients with CLI of any aetiology were eligible for inclusion. Surgical and revascularisation procedures, and all invasive interventions were excluded.Results Of 792 studies, six met full inclusion criteria. These studies researched the use of intravenous lidocaine, intravenous ketamine, oral gabapentin and the combination of transdermal buprenorphine and epidural morphine/ropivacaine infusion. All studies showed an improvement in severity of ischaemic pain in CLI but with varying side effect profiles and quality. The extracted studies showed substantial heterogeneity and therefore a meta-analysis was not performed.Conclusion The pharmacological management of pain secondary to non-reconstructable CLI is a challenging review topic. No recommendations of pharmacological agents can be made following this review but a number of novel approaches to manage pain in this cohort have shown positive results and require further investigation

Validation of the IPOS-Renal Symptom Survey in advanced kidney disease; a cross-sectional study

Context:The significant symptom burden in advanced renal disease is often poorly recognized by clinicians. Recently, the Integrated Palliative Outcome Score (IPOS) – Renal survey was developed from pre-existing tools to capture these symptoms and other common concerns. Objectives:We studied the validity and reliability of the IPOS-Renal survey (patient and staff versions) in an Australian population. Methods:Adult patients with advanced renal disease and nurses caring for them participated. We initially administered the IPOS-Renal survey simultaneously with other validated surveys, then re-tested the IPOS-Renal after 7-14 days. We tested the construct validity of (a) IPOS-Renal patient version in relation to the Edmonton Symptom Assessment Survey- revised and the KDQOL-SF v1.3 questionnaire; and (b) IPOS-Renal staff version in relation to the Support Team Assessment Schedule (STAS) survey. Results: 81 patients (65 haemodialysis, 10 peritoneal dialysis and 6 on supportive care; average age 64.9 years) and 53 nurses (average renal nursing experience 10.9 years) participated. Intra-class coefficients for test-retest reliability were >0.7 for most queries; Cronbach’s alpha for internal consistency was 0.84 (patient version) and 0.91 (staff version). In tests of construct validity, Spearman’s coefficient of correlation between surveys and their comparators for similar questions was significant, at 0.61 to 0.77 (patients) and 0.24 to 0.76 (staff). As expected, symptom scores and total symptom burden were negatively correlated with summary scores of quality of life. Conclusion:The IPOS-Renal surveys, patient and staff versions, have good test-retest reliability, internal consistency and construct validity in patients with advanced kidney disease and their nurses. We recommend their use in symptom assessment

Measuring health-related quality of life in patients with conservatively managed stage 5 chronic kidney disease: limitations of the Medical Outcomes Study Short Form 36: SF-36

© 2016, The Author(s). Purpose: Chronic kidney disease (CKD) negatively affects health-related quality of life (HRQoL), which is often measured using the Medical Outcomes Study Short Form 36 (SF-36) questionnaire. However, the adequacy of SF-36 in this population has not been reported. We aimed to determine floor and ceiling effects and responsiveness to change of SF-36 in patients with conservatively managed stage 5 CKD. Methods: SF-36 data were collected prospectively. Floor and ceiling effects were estimated for each SF-36 scale and summary measure based on raw scores. The minimal clinically important difference (MCID) was estimated using a combination of anchor-based and distribution-based methods. Responsiveness to change was assessed by comparing MCID for each scale and summary measure to its smallest detectable change. Results: SF-36 data were available for 73 of the 74 study participants. Using baseline data, floor and/or ceiling effects were detected for 3 of the 8 SF-36 scales. The anchor-based estimation of MCID based on differences in baseline functional status yielded the most reliable results. For the physical component summary, MCID was estimated at 5.7 points. Whilst the two SF-36 summary measures were responsive to change and free of floor and/or ceiling effects, six of the eight scales were not. Conclusions: This small study of patients with conservatively managed stage 5 CKD found that only the summary measures of SF-36 and 2 of its 8 scales can be used to assess changes in HRQoL over time. These findings suggest that in this population, alternative HRQoL assessment tools should be considered for future studies

Patient and health care professional decision-making to commence and withdraw from renal dialysis: A systematic review of qualitative research

Background and objectives. To ensure decisions to start and stop dialysis in end stage kidney disease are shared, the factors that affect patients and healthcare professionals in making such decisions need to be understood. This systematic review aims to explore how and why different factors mediate the choices about dialysis treatment. Design, setting, participants, and measurements. Medline, Embase, CINAHL and PsychINFO were searched for qualitative studies of factors that affect patients’ and/or healthcare professionals’ decisions to commence or withdraw from dialysis. A thematic synthesis was conducted. Results. Of 494 articles screened, 12 studies (conducted: 1985-2014) were included. These involved 206 predominantly haemodialysis patients and 64 healthcare professionals (age range: patients 26-93; professionals 26-61 years). (i) Commencing dialysis: patients based their choice on ‘gut-instinct’ as well as deliberating the impact of treatment on quality-of-life and survival. How individuals coped with decision-making was influential, some tried to take control of the problem of progressive renal failure, whilst others focussed on controlling their emotions. Healthcare professionals weighed-up biomedical factors and were led by an instinct to prolong life. Both patients and healthcare professionals described feeling powerless. (ii) Dialysis withdrawal: Only after prolonged periods of time on dialysis, were the realities of life on dialysis fully appreciated and past choice questioned. By this stage however patients were physically treatment dependent. Similar to commencing dialysis, individuals coped with treatment withdrawal in a problem or emotion-controlling way. Families struggled to differentiate choosing versus allowing death. Healthcare teams avoided and queried discussions regarding dialysis withdrawal. Patients however missed the dialogue they experienced during pre-dialysis education. Conclusions. Decision-making in end stage kidney disease is complex, dynamic, and evolves over time and towards death. The factors at work are multi-faceted and operate differently for patients and health professionals. More training and research on open-communication and shared decision-making is needed

A systematic review of the effectiveness of palliative interventions to treat rectal tenesmus in cancer

Background:Rectal tenesmus is a distressing symptom in patients with advanced cancer and challenging to treat. There is lack of consensus on the appropriate management of tenesmus in this patient population.Aim:To identify and examine the effectiveness of interventions to palliate rectal tenesmus caused by advanced cancer when surgery, radiotherapy or chemotherapy are no longer treatment options.Design:A systematic review of the literature following standard systematic review methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance.Data sources:A comprehensive search of the electronic databases MEDLINE, EMBASE and the Cochrane Library was conducted from date of inception to April 2016. PubMed ‘related articles’ search, grey literature search and hand-searches of the bibliographies of relevant papers and textbooks were also performed. Non-cancer patients were excluded. Any studies involving surgery or radiotherapy to treat tenesmus were excluded. Studies involving interventions to treat pelvic pain syndromes without specific outcome measures on severity of tenesmus were excluded. The quality of the studies was assessed using a National Institute for Health and Clinical Excellence–recommended quality assessment tool.Results:From 861 studies, 9 met full criteria and were selected. All were case series investigating the use of pharmacological interventions (diltiazem, nifedipine, methadone, mexiletine hydrochloride, lidocaine and bupivacaine), anaesthetic interventions (lumbar sympathectomy, neurolytic superior hypogastric plexus block), and endoscopic laser interventions. The included studies showed substantial heterogeneity, and therefore, a meta-analysis was not feasible.Conclusion:From this review, we identified a significant gap in research into the palliation of rectal tenesmus. A multimodal approach may be necessary due to the complexity of the pathophysiology of tenesmus. Future research should focus on randomised controlled trials of drug therapies whose potential effectiveness is suggested by case series

The Prepare for Kidney Care Study: prepare for renal dialysis versus responsive management in advanced chronic kidney disease

Shared decision making in advanced chronic kidney disease (CKD) requires unbiased information on survival and person-centred outcomes known to matter to patients: quality of life, symptom burden and support from family and healthcare professionals. To date, when deciding between dialysis and conservative care, patients have had to rely on evidence from small observational studies. Clinicians recognize that like is not being compared with like in these studies, and interpret the results differently. Furthermore, support differs considerably between renal units. What patients choose therefore depends on which renal unit they attend. To address this, a programme of work has been underway in the UK. After reports on survival and symptoms from a small number of renal units, a national, mixed-methods study-the Conservative Kidney Management Assessment of Practice Patterns Study-mapped out conservative care practices and attitudes in the UK. This led to the Prepare for Kidney Care study, a randomized controlled trial comparing preparation for dialysis versus preparation for conservative care. Although powered to detect a positivist 0.345 difference in quality-adjusted life years between the two treatments, this trial also takes a realist approach with a range of person-centred secondary outcomes and embedded qualitative research. To understand generalizability, it is nested in an observational cohort study, which is nested in a CKD registry. Challenges to recruitment and retention have been rapidly identified and addressed using an established embedded mixed methods approach-the QuinteT recruitment intervention. This review considers the background to and progress with recruitment to the trial

The effects of opioids on cognition in older adults with cancer and chronic non-cancer pain: A systematic review

ContextOpioids are prescribed to manage moderate to severe pain and can be used with older adults; however, they may lead to several adverse effects, including cognitive impairment.ObjectiveTo identify, appraise and synthesise evidence on i) the impact of opioids on cognition in older adults with cancer/chronic non-cancer pain, and ii) screening tools/neuropsychological assessments used to detect opioid-induced cognitive impairment.MethodsA systematic literature review following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PROSPERO Registration CRD42018092943). MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Library and Web of Science were searched up to December 2018. Randomised controlled trials, quasi-experimental studies and observational studies of adults aged ≥65 with cancer/chronic non-cancer pain taking opioids were included. A narrative synthesis was conducted.ResultsFrom 4,036 records, 10 met inclusion criteria. Five studies used one screening tool and five used a range of neuropsychological assessments; assessing 14 cognitive domains. Most studies demonstrated no effect of opioid use on cognitive domains, whilst four studies showed mixed effects. In particular, attention, language, orientation, psychomotor function and verbal working/delayed episodic memory were worsened. Changes to cognitive function were predominantly observed in studies with higher mean doses of opioids (120mg–190.7mg oral morphine equivalent daily dose).ConclusionBoth improvements and impairments to cognition were observed in studies with higher mean opioid doses. In clinical practice, a brief screening tool assessing attention, language, orientation, psychomotor function, and verbal working/delayed episodic memory, may be beneficial to detect worsening cognition in older adults with chronic pain using opioids

What are the main symptoms and concerns reported by patients with advanced chronic heart failure?—a secondary analysis of the Palliative care Outcome Scale (POS) and Integrated Palliative care Outcome Scale (IPOS)

© Annals of Palliative Medicine. All rights reserved. There is a lack of valid disease-specific patient-reported outcome measures (PROMs) for detecting symptoms and concerns in patients with advanced chronic heart failure (CHF). The Palliative care Outcome Scale (POS) and Integrated Palliative care Outcome Scale (IPOS) are specifically developed to capture the main symptoms and concerns of people severely affected by advanced disease. The aim of this study was to determine whether POS and IPOS captures the main symptoms and concerns self-reported by patients with advanced CHF. A secondary analysis of existing POS/IPOS data collected in three longitudinal studies was conducted. POS and IPOS start with an open-ended question for patients to report their main problems and concerns, followed by subsequent closed questions on a range of symptoms and other concerns. Descriptive statistics were used to report the results. The 102 participants from the three datasets had median age 81 years (SD ±9.84 years); 62% male; 87% white. A total of 107 concerns were reported in the first, open POS/IPOS question seeking the patient’s main concerns. Of these, 83 (77%) were reflected in the subsequent IPOS/POS closed questions. The high correspondence between the free-text responses and the closed questions indicates that most issues are captured by the POS/IPOS items. In conclusion, the generic versions of POS and IPOS do capture the main problems and concerns of patients with advanced CHF. Minor adaptations and further psychometric validation of POS and IPOS are needed in this population

Experiences of transitioning between settings of care from the perspectives of patients with advanced illness receiving specialist palliative care and their family caregivers: A qualitative interview study

Background: Transitions between care settings (hospice, hospital and community) can be challenging for patients and family caregivers and are often an under-researched area of health care, including palliative care. Aim: To explore the experience of transitions between care settings for those receiving specialist palliative care. Design: Qualitative study using thematic analysis. Setting/participants: Semi-structured interviews were conducted with adult patients (n = 15) and family caregivers (n = 11) receiving specialist palliative care, who had undergone at least two transitions. Results: Four themes were identified. (1) Uncertainty about the new care setting. Most participants reported that lack of information about the new setting of care, and difficulties with access and availability of care in the new setting, added to feelings of uncertainty. (2) Biographical disruption. The transition to the new setting often resulted in changes to sense of independence and identity, and maintaining normality was a way to cope with this. (3) Importance of continuity of care. Continuity of care had an impact on feelings of safety in the new setting and influenced decisions about the transition. (4) Need for emotional and practical support. Most participants expressed a greater need for emotional and practical support, when transitioning to a new setting. Conclusions: Findings provide insights into how clinicians might better negotiate transitions for these patients and family caregivers, as well as improve patient outcomes. The complexity and diversity of transition experiences, particularly among patients and families from different ethnicities and cultural backgrounds, need to be further explored in future research
