Life quality vs the 'quality of life': assumptions underlying prospective quality of life instruments in health care planning

A Sceptics Report: Canada's Five Years Experience with Medical Termination (MAiD)

This article seeks to assess the results of legislation legalizing medical termination, known in Canada as "medical aide in dying" in 2016. Its focus, like that of previous authors, is to ask if the concerns of skeptics opposed to legalization have been realized or were they unfounded. These include the likelihood of a "slippery slope" with an expanding definition of eligibility and of MAiD deaths. Of similar concern at least since 1995 was the likelihood that, in the absence of the provision of palliative, rehabilitative, psychological and social services that medical termination would be a substitute for good medical care. These and other concerns are the basis for the review of MAiD in Canada clinically, legally and as an ethical construct.

Quality of Life Associated with Open vs Minimally Invasive Pancreaticoduodenectomy: A Prospective Pilot Study

BACKGROUND

This prospective study was designed to compare quality of life (QoL) among patients who underwent open (O-PD) vs minimally invasive pancreaticoduodenectomy (MI-PD), using a combination of validated qualitative and quantitative methodologies.

STUDY DESIGN

From 2017 to 2019, patients scheduled for pancreaticoduodenectomy (PD) were enrolled and presented with Functional Assessment of Cancer Therapy-Hepatobiliary surveys preoperatively, before discharge, at first postoperative visit and approximately 3 to 4 months after operation ("3 months"). Longitudinal plots of median QoL scores were used to illustrate change in each score over time. In a subset of patients, content analysis of semistructured interviews at postoperative time points (1.5 to 6 months after operation) was conducted.

RESULTS

Among 56 patients who underwent PD, 33 had an O-PD (58.9%). Physical and functional scores decreased in the postoperative period but returned to baseline by 3 months. No significant differences were found in any domains of QoL at baseline and in the postoperative period between patients who underwent O-PD and MI-PD. Qualitative findings were concordant with quantitative data (n = 14). Patients with O-PD and MI-PD reported similar experiences with complications, pain, and wound healing in the postoperative period. Approximately half the patients in both groups reported "returning to normal" in the 6-month postoperative period. A total of 4 patients reported significant long-term issues with physical and functional well-being.

CONCLUSIONS

Using a novel combination of qualitative and quantitative analyses in patients undergoing PD, we found no association between operative approach and QoL in patients who underwent O-PD vs MI-PD. Given the increasing use of minimally invasive techniques for PD and the steep learning curve associated with these techniques, continued assessment of patient benefit is critical.

Health-related quality of life associated with nocturnal leg cramps in primary care: a mixed methods study

BACKGROUND

Although nocturnal leg cramps are common, little research is available about their impact on quality of life. This mixed-methods study explored the impact of nocturnal leg cramps on health-related quality of life (HRQoL).

METHODS

The study included primary care patients (>50 years) who reported suffering from nocturnal leg cramps (2016-2017). In the quantitative phase, patients completed a questionnaire about their HRQoL (SF-36) and the frequency of their cramps, and we computed the SF-36 scores. Then, we conducted a qualitative study using semi-structured interviews with patients with various levels of HRQol to explore their perception of the impact of cramps on their lives.

RESULTS

A total of 114 patients (49%) agreed to participate in the quantitative study (mean age: 71, women: 62%) and 15 patients were included in the qualitative study (mean age: 69, women: 67%). The number of cramps in the previous week was low (mean: 1.6 (SD 1.5)). The SF-36 mean physical and mental summary scores were 43 and 50, respectively, and the domain scores were similar to a comparative general population. Whilst some patients reported little interference with their daily lives, others reported a major decrease in their HRQoL. SF-36 scores were not sufficient to describe the cramp-related impairment, as patients from all levels of SF-36 scores reported major impacts of NLC in the interviews.

CONCLUSIONS

Some patients describe a specific impact of cramps on their lives, regardless of their HRQoL. These patients should be the target of future intervention trials.

Disabling disability amid competing ideologies

This paper critiques current arguments advancing the potential for transhumanism and a range of biological and pharmacological enhancements to better human flourishing. It does so from a historical perspective weighing the individualistic and competitive evolutionary theories of Darwin with the cooperative and communal theories of Prince Peter Kropotkin a generation later. In doing so it proposes the transhumanist and enhancement enthusiasts operate within a paradigm similar to Darwin's, one that is atomist and individualistic. The critique, which considers the status of those with cognitive, sensory and physical limits, advances a vision of society as a cooperative and communal rather than individualistic and competitive. Within this framework the argument is not one of either/or but on the lexicographical superiority of the communal and social over the individualistic and competitive ethos underlying both Darwin and most contemporary transhumanist literature. This reordering of priorities, it is argued, reflects advances in contemporary biology and evolutionary thinking.

Quantifying life: Understanding the history of Quality-Adjusted Life-Years (QALYs)

Quality-Adjusted Life-Years (QALYs) are central to healthcare decision-making in Britain and abroad, yet their history is poorly understood. In this paper, we argue that a more in-depth and political history of the QALY is needed to allow a critical evaluation of its current dominance. Exploiting rich data from archives and 44 semi-structured interviews conducted between 2015 and 2018, we employ Multiple Streams Analysis to construct a complex and dynamic picture of how the idea of QALYs emerged and was adopted within UK health policy. Through its historical and political approach, the paper illuminates the relative roles in the policy-making process of experts (especially economists) and politicians as 'entrepreneurs' in the development of new ideas; how these were influenced by negotiation within established and emerging institutional structures; and the role of serendipity and crisis.

A review of the application, feasibility, and the psychometric properties of the individualized measures in cancer

PURPOSE

To identify from the published literature the feasibility and the application of the individualized measures [Patient Generated Index (PGI), Schedule for the Evaluation of Individual Quality of Life (SEIQOL), and the short form of it (the direct weighting SEIQOL-DW)] in the context of cancer and to summarize the evidence on the psychometric properties of these measures.

METHODS

Ovid Medline, PubMed, Embase, and CINAHL were searched up to April 2016. All studies were included if they reported information about the psychometric properties of the individualized measures and included patients diagnosed with any type of cancer at any age. Effect size (ES) was calculated to test for the responsiveness.

RESULTS

Fifty-four full articles were reviewed. Full-text assessment of these articles resulted in 27 eligible studies that were included in our analysis. The majority of the studies (81%) reported data on the SEIQOL-DW, and only 15% on the PGI. Fourteen areas of quality-of-life (QOL) concerns were identified by patients using the PGI with the top 4 being family (90%), health (85%), finance (85%), and work (80%). At the global level, the correlation between the individualized and standard measures ranged from 0.45 to 0.49 and, at the symptom level, from 0.26 to 0.51. The ES of the individualized measures was high (ranged from 0.98 to 1.0) in the studies that expected high positive change compared to standard QOL measures (ES = 0.1).

CONCLUSION

Individualized measures are feasible and acceptable among people with cancer and could easily be incorporated clinically and used in a research context. Individualized measures are sensitive to change and cover a wide range of patients QOL concerns in comparison with standard measures.

Health-related quality of life in patients with serious non-specific symptoms undergoing evaluation for possible cancer and their experience during the process: a mixed methods study

PURPOSE

The purpose of this research was to measure changes in HRQoL during the diagnostic evaluation of patients presenting with non-specific symptoms possibly attributable to cancer, to describe their experiences of HRQoL and to merge these findings with intent to obtain a more comprehensive understanding of their HRQoL experience during this stressful life event.

METHODS

A convergent mixed methods (MM) design was used and involved quantitative data about HRQoL measured by the EORTC-QLQ-C30 instrument and qualitative interview data about patients' HRQoL experiences. Participants completed the EORTC-QLQ-C30 questionnaire prior to and after evaluation. The baseline questionnaire informed the purposive sampling for the qualitative interview study, and open-end questions matched to the EORTC-QLQ-C30 constructs were used in the semi-structured interviews.

RESULTS

A total of 838 patients were enrolled in the quantitative study; 680 (81 %) also completed follow-up. Twenty-one patients participated in interviews. The MM findings are the meta-inferences drawn by looking across the matched quantitative and qualitative findings: physical function, social function, role function, emotional function, cognitive function, social function, symptoms and quality of life.

CONCLUSION

The survey results illustrate that HRQoL improved over time and the qualitative findings confirmed and further expanded the survey results. The MM analysis underlines that the HRQoL experience cannot be observed independently from context. Participants adapted to their situation over time, and this may change their perceptions of HRQoL. These findings can be used to enhance evidence-based care as clinicians need to be aware of how the context influences the HRQoL experience.

Anthropometric measures change and quality of life in elderly people: a longitudinal population-based study in Southern Brazil

PURPOSE

To analyze the effects of anthropometric measures change on quality of life (QoL) in elderly, using measured anthropometric data on body mass index (BMI) and waist circumference (WC).

METHOD

Population-based cohort study investigating a sample of elderly (≥60) assessed in 2009 (n = 1705) and followed up in 2013 (n = 1197). QoL was evaluated in 2013 using the CASP-19. Variables evaluated as exposure including BMI and WC in 2009 (both standardized), categories of anthropometric measures change from 2009 to 2013 (excess weight = BMI ≥ 25.0 kg/m²; large WC = top quartile), and the absolute BMI and WC change in same period. Multivariate linear regressions adjusted for possible confounding factors and mediators were used.

RESULTS

Both BMI and WC at baseline were associated with lower QoL scores, even after adjustment for confounding variables (β _BMI = -0.9; 95 % CI -1.5; -0.3 and β _WC = -1.0; 95 % CI -1.7; -0.4). Additionally, QoL scores were lower among elderly with excess weight (β = -1.4; 95 % CI -2.9; 0.0) or large WC (β = -3.3; 95 % CI -5.2; -1.4) in both waves than among those whose BMI and WC were always normal, but changes in anthropometric measures did not affect QoL. The presence of chronic diseases was a partial mediator of these associations, especially for effects of BMI change. Anthropometric measures change treated as a continuous variable was not associated with QoL.

CONCLUSIONS

Having excess weight and large WC in both waves was associated with lower QoL scores in elderly, but changing the anthropometric measures did not affect this outcome. Maintaining weight and WC within normal limits during aging can help to preserve QoL.

Putting Gino's lesson to work: Actor-network theory, enacted humanity, and rehabilitation

This article argues that rehabilitation enacts a particular understanding of "the human" throughout therapeutic assessment and treatment. Following Michel Callon and Vololona Rabeharisoa's "Gino's Lesson on Humanity," we suggest that this is not simply a top-down process, but is cultivated in the application and response to biomedical frameworks of human ability, competence, and responsibility. The emergence of the human is at once a materially contingent, moral, and interpersonal process. We begin the article by outlining the basics of the actor-network theory that underpins "Gino's Lesson on Humanity." Next, we elucidate its central thesis regarding how disabled personhood emerges through actor-network interactions. Section "Learning Gino's lesson" draws on two autobiographical examples, examining the emergence of humanity through rehabilitation, particularly assessment measures and the responses to them. We conclude by thinking about how rehabilitation and actor-network theory might take this lesson on humanity seriously.

Quality of life and health of opioid-dependent subjects in India

BACKGROUND AND OBJECTIVES

The quality of life (QoL) of substance abusers is known to be severely impaired. This study was carried out to assess the impact of opioid dependence on the QoL of subjects and compared it with the normal subjects.

MATERIALS AND METHODS

Based on specified inclusion criteria a total of 47 subjects were recruited from a tertiary care center from India. The WHOQoL-BREF scale domain scores obtained at baseline were compared to that of normal subjects. An assessment of dysfunction and reasons for continuing and other parameters were assessed.

RESULTS

WHOQoL-BREF domains (Physical, Psychological, Social relationships and Environment) showed significantly lower scores and the difference was statistically significant.

INTERPRETATION AND CONCLUSIONS

The results showed that QoL is an important parameter in assessment of substance abusers and can be used for long-term prognosis of these individuals.

Parallels and problems of normalization in rehabilitation and universal design: enabling connectivities

PURPOSE

Universal design (UD) is oriented to creating products, buildings, outdoor spaces and services for use by all people to the fullest extent possible according to principles of enabling equal citizenship. Nevertheless its theoretical basis has been under-explored, a critique that has also been leveled at rehabilitation. This commentary explores parallels between UD and dominant rehabilitation discourses that risk privileging or discrediting particular ways of being and doing.

METHODS

Commentary.

RESULTS

Drawing from examples that explore the intersection of bodies, places and technologies with disabled people, I examined how practices of normalization risk reproducing the universalized body and legitimated forms of mobility, and in so doing perpetuates the "othering" of difference. To address these limitations, I explored the postmodern notion of multiple creative "assemblages" that are continually made and broken over time and space. Assemblages resist normalization tendencies by acknowledging and fostering multiple productive dependencies between human and non-human elements that include diverse bodies, not just those labeled disabled.

CONCLUSION

In exploring the potential of enhancing creative assemblages and multiple dependencies, space opens up in UD and rehabilitation for acknowledging, developing, and promoting a multiplicity of bodily forms and modes of mobility. Implications for Rehabilitation Universal design and rehabilitation both risk perpetuating particular ideas about what disabled people should be, do, and value, that privilege a limited range of particular bodily forms. The notion of "assemblages" provides a conceptual tool for rethinking negative views of dependence and taken for granted independence goals. In exploring the potential of enhancing various dependencies, space opens up for reconsidering disability, mobility and multiple ways of "doing-in-the-world".

Clinical, psychosocial, and central correlates of quality of life in myotonic dystrophy type 1 patients

AIMS

To identify sociodemographic, clinical, and central correlates of health-related quality of life (HRQoL) in DM1 patients.

METHODS

200 DM1 patients had assessments of muscular impairment, CTG repeats, and intelligence. Validated instruments were used to assess sociodemographic and clinical factors as well as social support, social participation, daytime sleepiness, fatigue, personality, mood, and quality of life. Regression analysis was used to identify correlates of SF-36 physical and mental component summary scores.

RESULTS

Patients scored lower on all SF-36 physical health subscales compared with normative data but did not differ with respect to mental health function. Regression analysis revealed that psychological distress, fatigue, severe muscular impairment, emotional stability, not having worked within the last 12 months, and lower intellectual quotient were associated with lower scores in physical health function. Moreover, neuroticism, daytime sleepiness, dissatisfaction with social participation, and lower conscientiousness were associated with lower scores in mental health function.

CONCLUSION

DM1 has an impact on SF-36 physical summary scores but not on mental summary scores. Factors such as fatigue, daytime sleepiness, psychological distress, unemployment, and social participation dissatisfaction that significantly affect HRQoL in DM1 are amenable to treatment and psychosocial interventions, namely by providing care that integrate health, social, and community services.

The social and ethical implications of changing medical technologies: the views of people living with genetic conditions

This article presents empirical data on subjective levels of health and quality of life for individuals with early- or late-onset genetic conditions. Twelve adults with an early-onset condition (cystic fibrosis) and 12 adults with a late-onset condition in the family (Huntington's disease) participated in semi-structured interviews. Questions investigated perceptions of the body, quality of life and views on medical technology and testing. Transcripts were thematically analysed using a qualitative methodology (interpretative phenomenological analysis). The article focuses on the superordinate theme of 'What is a life worth living?'. Different emphases in judgements and definitions of quality of life were uncovered. At the same time the article emphasizes the convergence between the two groups in terms of overall views of quality of life and confirms that the voices of people living with genetic conditions should form part of wider bioethical debates arising from such advances.

Domains and determinants of quality of life in schizophrenia and systemic lupus erythematosus

BACKGROUND

The World Health Organization Quality of Life-Bref (WHOQOL-Bref) scale was designed to measure quality of life (QOL) in both medical and psychiatric illnesses. There have been a few studies to date that compare aspects of QOL in medical and psychiatric illnesses.

AIM

The aim of the study was to compare QOL in patients with systemic lupus erythematosus (SLE), a chronic medical illness and schizophrenia, a chronic psychiatric disorder.

MATERIALS AND METHODS

In a prospective design, 50 patients with SLE and 50 patients with schizophrenia were assessed on measures of QOL by using the WHOQOL-Bref scale, demographic factors, disease severity, and psychiatric comorbidity.

RESULTS

There was a significant difference between the SLE group and the schizophrenia group on the social domain of the WHOQOL-Bref scale but not on other domains. Patients with SLE had lower scores, except on social domain. Disease severity correlated with scores on the physical domain and environmental domain in both illnesses. The presence of psychiatric comorbidity was associated with significantly lower QOL scores in SLE. The presence of insight was associated with nonsignificantly lower QOL scores in schizophrenia. There was a significant association between QOL scores and both income and religious belief system in SLE, while age and duration of illness correlated with QOL scores in schizophrenia.

CONCLUSION

Although the QOLs in schizophrenia and SLE were comparable on all domains except the social domain, the factors that mediate QOL in both these illnesses are different.

Comparing two versions of the Schedule for Evaluation of Individual Quality of Life in patients with advanced cancer

BACKGROUND

The aim was to compare two individualized patient reported outcomes or the Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW) measuring quality of life in general, and the disease-related version (SEIQoL-DR) measuring quality of life related to disease. Both instruments have been used in clinical practice settings within oncology. The instruments were compared with regard to feasibility, the areas nominated by patients as important and patients' ratings of how they were doing in these areas (Index scores).

MATERIAL AND METHODS

The study included 40 patients with gastrointestinal cancer. All patients completed both versions of the instrument on a touch screen computer in relation to a medical consultation. Firstly, the participants were invited to nominate the five domains she/he currently considered to be most important in life. Secondly, they were asked to rate how they were doing in each of these domains. Finally, they were asked to quantify the relative importance of each area. Cohen's effect sizes were calculated to illuminate the clinical importance of mean value differences.

RESULTS

Both instruments took less than ten minutes to complete and the procedure was considered feasible by both patients and interviewers. The proportion of patients nominating the same areas in the two versions did not differ, however, the SEIQoL-DW Index score was significantly higher than the corresponding score for the SEIQoL-DR. The detected difference in the mean score measured by effect size was medium.

CONCLUSION

The magnitude of the effect size of the difference in Index score imply that the two versions tap into different constructs, i.e. quality of life (QoL) versus health-related QoL (HRQL), supporting the construct validity of the two versions of the instrument. The SEIQoL-DW and the SEIQoL-DR should be considered as complementary rather than interchangeable when used in patients with cancer.

A systematic review of quality of life in adults with muscle disease

We reviewed the literature on how muscle disease affects quality of life compared to healthy controls, and the factors that influence the effects of muscle disease on quality of life. We also wanted to know whether quality of life differed between muscle diseases. We searched online databases and identified 26 relevant studies. The quality of each study was assessed, results sections analysed and a database of factors associated with quality of life developed. We graded the level of evidence supporting the association between each factor and quality of life as inconclusive, moderate or high. Compared to controls, muscle disease compromised quality of life in all areas of functioning. There was little evidence to suggest that quality of life differed significantly between muscle diseases. There was a high level of evidence suggesting that disease severity, pain, fatigue, and mood significantly affect quality of life. There was a moderate level of evidence suggesting that illness perceptions, coping strategies, age and gender affect quality of life. Several factors had an inconsistent level of evidence.

Eugenics and the genetic challenge, again: all dressed up and just everywhere to go

Dashiell Hammett’s reaction was “sharp and angry, snarling” when he read, at her request, a work in progress by his friend and lover, Lillian Hellman. “He spoke as if I had betrayed him.” His judgment was absolute and his advice unsparing: “Tear this up and throw it away. It’s worse than bad—it’s half good.” That is exactly what I thought of Matti Häyry’sRationality and the Genetic Challengeas, for the third time in the evening, I penned a note in its margins and sent it sailing across the room in disgust. Cambridge University Press knows its book binding, however, and the spine of the text was undamaged.

Enhancing who? Enhancing what? Ethics, bioethics, and transhumanism

Transhumanists advance a "posthuman" condition in which technological and genetic enhancements will transform humankind. They are joined in this goal by bioethicists arguing for genetic selection as a means of "enhancing evolution," improving if not also the species then at least the potential lives of future individuals. The argument of both, this paper argues, is a new riff on the old eugenics tune. As ever, it is done in the name of science and its presumed knowledge base. As ever, the result is destructive rather than instructive, bad faith promoted as high ideal. The paper concludes with the argument that species advancement is possible but in a manner thoroughly distinct from that advanced by either of these groups.

Has the time come for cost-effectiveness analysis in US health care?

Cost-effectiveness analysis (CEA) is a powerful analytic tool for assessing the value of health care interventions but it is a method used sparingly in the US. Despite its growing acceptance internationally and its endorsement in the academic literature, most policy analysts have assumed that US decision makers will resist using CEA to inform coverage decisions. This study sought to clarify the extent to which CEA is understood and accepted by US decision makers, including regulators, private and public insurers, and purchasers, and to identify their points of difficulty with its use. We conducted half-day workshops with a sample of six California-based health care organizations that spanned a range of public and private perspectives regarding coverage of health care services. Each workshop included an overview of CEA methods, a priority-setting exercise that asked participants (acting as ‘social decision makers’) to rank condition treatment pairs prior to and following provision of cost-effectiveness information; and a facilitated discussion of obstacles and opportunities for using CEA in their own organizations. Pre and post-questionnaires inquired as to obstacles toward implementing CEA, attitudes toward rationing, and views on the use of CEA in Medicare and in private insurance coverage decision-making. In post-workshop surveys major obstacles identified included: fears of litigation, concerns about the quality and accuracy of studies that were commercially sponsored, and failure of CEAs to address shorter horizon cost implications. Over 90% of participants felt that CEA should be used as an input to Medicare coverage decisions and 75% supported its use in such decisions by private insurance plans. Despite the wide acceptance of CEA, at the conclusion of the workshop, 40% of the sample remained uncomfortable with support of ‘rationing’ per se. We suggest that how cost-effectiveness analysis is framed will have important implications for its acceptability to US decision makers.

Future directions for investigation of fatigue in chronic hepatitis C viral infection

Fatigue is a common and often debilitating symptom for people living with chronic hepatitis C viral infection. Numerous published reports in the past decade have attempted to address the nature and aetiology of fatigue in chronic hepatitis C; however, this field is plagued with lack of clarity about how hepatitis C virus (HCV)-related fatigue occurs and when it is experienced by the infected person. Consequently, both patients and clinicians alike are unclear about how to mediate or prevent the negative consequences of HCV-related fatigue. In the following article, the authors identify areas of ambiguity and incongruity that have evolved primarily from the underlying assumptions and methodological decisions of researchers in the field of HCV-related fatigue. Research related to fatigue in chronic illness is drawn upon to suggest future directions for investigations and interventions in the field of HCV-related fatigue. Future research needs to move beyond the subjective symptomatology of HCV-related fatigue and begin to account for the multidimensional and contextualised nature of the fatigue experience.

Injection Drug User Quality of Life Scale (IDUQOL): findings from a content validation study

Background

Quality of life studies among injection drug users have primarily focused on health-related measures. The chaotic life-style of many injection drug users (IDUs), however, extends far beyond their health, and impacts upon social relationships, employment opportunities, housing, and day to day survival. Most current quality of life instruments do not capture the realities of people living with addictions. The Injection Drug Users' Quality of Life Scale (IDUQOL) was developed to reflect the life areas of relevance to IDUs. The present study examined the content validity of the IDUQOL using judgmental methods based on subject matter experts' (SMEs) ratings of various elements of this measure (e.g., appropriateness of life areas or items, names and descriptions of life areas, instructions for administration and scoring).

Methods

Six SMEs were provided with a copy of the IDUQOL and its administration and scoring manual and a detailed content validation questionnaire. Two commonly used judgmental measures of inter-rater agreement, the Content Validity Index (CVI) and the Average Deviation Mean Index (AD_M), were used to evaluate SMEs' agreement on ratings of IDUQOL elements.

Results

A total of 75 elements of the IDUQOL were examined. The CVI results showed that all elements were endorsed by the required number of SMEs or more. The AD_M results showed that acceptable agreement (i.e., practical significance) was obtained for all elements but statistically significant agreement was missed for nine elements. For these elements, SMEs' feedback was examined for ways to improve the elements. Open-ended feedback also provided suggestions for other revisions to the IDUQOL.

Conclusion

The results of the study provided strong evidence in support of the content validity of the IDUQOL and direction for the revision of some IDUQOL elements.

Selected Primary Care Issues and Comorbidities in Children Who Are on Maintenance Dialysis: A Review for the Pediatric Nephrologist

Ten-year survival of all children who initiate dialysis at any age now approaches 70%, and in the older child this number is closer to 80%. These children will live with chronic kidney disease and its myriad of associated comorbidities during and throughout their childhood. Their care is complex and requires both teamwork and careful attention paid to maintaining lines of communication among patient, family, and both the facility-based nephrology team and caregivers who are outside the hospital setting. Irrespective of their need for dialysis, children with ESRD deserve and require developmentally appropriate care and anticipatory guidance with respect to primary care issues of childhood. The child who is on dialysis often is cared for solely or in large part by a nephrology service, therefore this review discusses issues that are particularly important to pediatric nephrologists in relation to selected primary care issues and comorbidities for the child who is on dialysis, with an emphasis on medical and psychosocial issues, and with particular weight placed on issues that are pertinent to the adolescent dialysis patient.

Measuring quality of life in prosthetic practice: benefits and challenges

There is an increasing awareness that the inclusion of quality of life as an outcome measure is important in ensuring a client-centred and holistic assessment. This review outlines the benefits of quality of life as an outcome measurement in the field of prosthetics. It introduces the key concepts and challenges in the definition and assessment of quality of life post-amputation, including the relative advantages and disadvantages of adopting generic, disease/condition specific, dimension specific and individualized measures of quality of life. In conclusion, the review delineates and recommends issues and guidelines for consideration when undertaking quality of life research and assessment. A co-ordinated approach by practitioners in the field of prosthetics is necessary to ensure the inclusion of quality of life as an outcome measure and to ensure its measurement in a standardized and rigorous manner.

Hospice - the ideology and perspectives in Estonia

BACKGROUND

Death and dying tend to be taboo for much of humankind. Themes about death and life ending have not been popular in Estonia because of its cultural traditions and history.

AIMS

To describe the attitudes of Estonian professionals towards death and dying and to describe some future visions of hospice service in Estonia.

METHODS

The theoretical view in this work comes from hospice conception and empirical data gained from structured interviews with professionals who are connected with dying people in their everyday work.

FINDINGS

Some ideas of the hospice conception (e.g. pain control and psychosocial support) are used in hospitals and general care centres in Estonia, but there is little respect towards dying people and their needs. The idea of interdisciplinary teamwork is not in use.

Children's and young people's experiences of chronic renal disease: a review of the literature, methodological commentary and an alternative proposal

AIM

The aims of this paper were to review and critique existing research literature on children's and young people's experiences of chronic renal disease and to propose alternative approaches that may be more fruitful in addressing existing research shortcomings.

BACKGROUND

Chronic renal disease, which results in approximately 1.6-4 new cases per year per million population in the 0-15 years age group, is a serious illness that causes severe and irreversible reduction in kidney function. Despite modern medical advances, its significance and implications for the lives of the children and young people concerned are profound.

METHOD

Salient literature for this review was obtained using the major health and social science electronic databases such as Medline, CINAHL, Psyclit and Sociofile. Manual searching of relevant books, journals and 'grey literature', combined with the genealogy approach, extended and strengthened the search.

CONCLUSIONS

Research in this area focuses mainly on two areas, namely psychological adjustment and adaptation to end-stage renal disease. This research is grounded within a framework of empirical psychology that values objectivity, measurement and quantification. This predominantly psychometric approach is critiqued for simplifying the complex experience of end-stage renal disease and for pathologizing children and young people with this disease. We identify a significant gap in the research literature, namely the lack of research that takes into account these children's and young peoples'own perspectives of their experiences.

RELEVANCE TO CLINICAL PRACTICE

Chronic renal disease has a significant impact on children's and young people's lives. Understanding the experiences of these children is important for the provision of effective healthcare. Conducting child-centred qualitative research in this area would allow us to explore vital questions of meaning, perception and understanding. If health and social care organizations claim to provide 'consumer-focused' services, it behoves us to develop first a clearer understanding of the lives and experiences of children and families who seek our help and to use this knowledge and understanding to plan and provide more grounded and responsive services.

Injection Drug Use Quality of Life scale (IDUQOL): a validation study

BACKGROUND

Existing measures of injection drug users' quality of life have focused primarily on health and health-related factors. Clearly, however, quality of life among injection drug users is impacted by a range of unique cultural, socioeconomic, medical, and geographic factors that must also be considered in any measure. The Injection Drug User Quality of Life (IDUQOL) scale was designed to capture the unique and individual circumstances that determine quality of life among injection drug users. The overall purpose of the present study was to examine the validity of inferences made from the IDUQOL by examining the (a) dimensionality, (b) reliability of scores, (c) criterion-related validity evidence, and (d) both convergent and discriminant validity evidence.

METHODS

An exploratory factor analysis using principal axis factoring in SPSS 12.0 was conducted to determine whether the use of a total score on the IDUQOL was advisable. Reliability of scores from the IDUQOL was obtained using internal consistency and one-week test-retest reliability estimates. Criterion-related validity evidence was gathered using variables such as stability of housing, sex trade involvement, high-risk injection behaviours, involvement in treatment programs, emergency treatment or overdose over the previous six months, hospitalization and emergency treatment over the subsequent six month period post data collection. Convergent and discriminant validity evidence was gathered using measures of life satisfaction, self-esteem, and social desirability.

RESULTS

The sample consisted of 241 injection drug users ranging in age from 19 to 61 years. Factor analysis supports the use of a total score. Both internal consistency (alpha = .88) and one-week test-retest reliability (r = .78) for IDUQOL total scores were good. Criterion-related, convergent, and discriminant validity evidence supports the interpretation of IDUQOL total scores as measuring a construct consistent with quality of life.

CONCLUSION

The findings from this study provide initial evidence to support the use of the IDUQOL total score. The results of the study also suggest the IDUQOL could be further strengthened with additional attention to how some IDUQOL domains are described and satisfaction is measured.

Evaluating health-related quality-of-life studies in paediatric populations: some conceptual, methodological and developmental considerations and recent applications

Although numerous paediatric-based health-related quality-of-life (HR-QOL) instruments are currently in use, there still remain conceptual, methodological and developmental issues to address. This paper provides an up-to-date critical review of the HR-QOL literature in paediatric medicine. Our analysis indicates that there is no consensus on how HR-QOL and overall QOL should be defined and measured in children. It is recommended that future studies focus on operationalising and distinguishing these constructs from each other and from traditional health-status measures. A clear empirical basis for generating instrument items and for prioritising specific domains must be described. Researchers should consider using the data gathered during their first interviews as a springboard from which to test their ideas of HR-QOL and QOL, reformulate concepts and subsequently retest their notions before developing instruments. Related to methodological challenges, consistency and agreement are still used interchangeably when comparing child and parent reports of children's HR-QOL. The Pearson correlation is a measure of co-variation in scores, and not a measure of agreement. We recommend that researchers focus on determining agreement as opposed to consistency. Few, if any, attempts have been made to account for the possibility that a response shift may have occurred in the evaluation of HR-QOL. Most studies have compared HR-QOL scores of children with illness with their healthy peers. As such, there is a dearth of knowledge regarding the normative process of adaptation within the context of illness. It is recommended that researchers focus on gathering data using a relative standard of comparison. We further recommend that researchers interpret HR-QOL data in line with their intended purpose. Regarding developmental consideration, particular attention ought to be paid to developing instruments that consider children's emerging sense of self, cognitive capacity and emotional awareness. Instruments that include items that are age appropriate are more likely to maximise reliability and validity of reports. The results of many HR-QOL instruments are applied in pharmacotherapeutic and pharmacoeconomic assessments. However, there has been relative infrequent application of economically valid HR-QOL tools (utility scales) and the use of HR-QOL scales as outcome measures in paediatric drug trials. As such, few cost-utility analyses have been performed to inform paediatric decision making. In addition, many of the concerns in the development of HR-QOL instruments should also be applied to the utility scales such that they reflect adequately children's preferences for health states.

Wellness Lifestyles I: A Theoretical Framework Linking Wellness, Health Lifestyles, and Complementary and Alternative Medicine

Scholarship concerning complementary and alternative medicine (CAM) practices within the United States could benefit from incorporating sociological perspectives into the development of a comprehensive research agenda. We review the literature on health and wellness emphasizing definitions and distinctions, the health lifestyles literature emphasizing issues of both life choices and life chances, and studies of CAM suggesting utilization as an aspect of a wellness lifestyle. This review forms the foundation of a new theoretical framework for CAM research based on the interrelationship of CAM with health promotion, wellness, and health lifestyles. To date, few studies have sought to bring these various elements together into a single, comprehensive model that would enable an assessment of the complexity of individual health and wellness in the context of CAM. We argue that attention to literatures on health measurement and health lifestyles are essential for exploring the effectiveness and continuing use of CAM.

A new instrument for assessing quality of life in atopic dermatitis: international development of the Quality of Life Index for Atopic Dermatitis (QoLIAD)

BACKGROUND

Atopic dermatitis (AD) is a chronic or chronically relapsing inflammatory skin condition that can have a considerable impact on those affected. There are a number of instruments available to measure outcome in dermatological conditions but none have been developed specifically for AD. In addition, most measure symptoms and/or daily functioning, which are potential influences on quality of life (QoL) rather than assessments of the construct itself.

OBJECTIVES

The aim of the current study was to develop a new instrument specifically designed to measure QoL in adults with AD-the Quality of Life Index for Atopic Dermatitis (QoLIAD).

METHODS

The instrument was developed based on the needs-based model of QoL and was produced in several different countries simultaneously. Its content was derived from 65 in-depth interviews with relevant patients in the U.K., Italy and the Netherlands. The initial version of the measure was produced in U.K. English and translations were produced for the Netherlands, Italy, Germany, France and the U.S.A. using a dual translation panel methodology. A Spanish version was developed using the same adaptation process after the instrument was finalized. Field-test interviews were conducted with approximately 20 patients in each country to assess face and content validity. The instrument [in addition to the Dermatology Life Quality Index (DLQI) and the Psychological General Well-Being Schedule (PGWB)] was then administered to up to 300 AD patients in each country at two time points to finalize the instrument and test its psychometric properties.

RESULTS

The initial version of the QoLIAD had 56 items that reflected the areas of need fulfillment identified in the qualitative interviews as having been affected by AD: mental and emotional stimulation, physical and emotional stability, security, sharing and belonging, self-esteem, personal development and fulfillment. Comments from patients in field-test interviews resulted in the removal of 14 items, to leave a 42-item instrument that was considered relevant and acceptable. The number of patients participating in the survey were 286 in the U.K., 46 in the Netherlands, 213 in France, 187 in Germany, 178 in the U.S.A. and 83 in Spain. Application of the Rasch model to these data identified the final 25-item QoLIAD. Unidimensionality was confirmed, with deviation of the total scale from the Rasch model evident at a single time point in one country only (the U.K.). All language versions, with the exception of the Dutch measure, had test-retest reliability coefficients in excess of 0.85. The test-retest in the Netherlands was 0.80. However, this country had the smallest sample size and the corresponding reliability for the DLQI was only 0.40. The QoLIAD had adequate internal consistency and the initial indications of construct validity were good. The levels of association with the DLQI indicated that the two instruments measure related but distinct constructs.

CONCLUSIONS

The QoLIAD is a practical, reliable, valid and culturally applicable instrument for measuring the impact of AD and its treatment on QoL in clinical trials or in routine clinical practice.

Assessing the quality of life of patients in phase I and II anti-cancer drug trials: interviews versus questionnaires

This paper discusses two different approaches to assessing quality of life in the context of cancer clinical trial participation. Drawing on empirical evidence from a study of patients' experiences of phase I and II anti-cancer drug trial participation, the paper demonstrates how different methods of collecting data about an individual's quality of life (questionnaires and interviews) can lead to alternative conclusions about patients' trial experience and the impact of trial involvement on their quality of life. Data obtained from the quality of life questionnaires interestingly revealed no statistically significant differences in any of the scores over time while in-depth interviews uncovered something of the psychological, emotional and social impact of taking part in a clinical trial from the perspective of the patient. The paper concludes by reflecting on some of the methodological issues that arise when assessing the quality of life of patients with a life threatening disease in clinical trials.

Quality of life in psychogenic nonepileptic seizures

PURPOSE

Psychogenic nonepileptic seizures (PNESs) are events that alter or seem to alter the neurologic function and, in their appearance, resemble epileptic seizures (ESs). In patients with ESs the psychological and medical aspects of epilepsy greatly influence the health-related quality of life (HRQOL). The relation between these factors and PNESs is not well established. In this study, we compared HRQOL in patients with PNESs with that of patients with ESs.

METHODS

We evaluated 105 patients admitted to the Epilepsy Monitoring Unit of University Hospital between January 20, 2001, and January 20, 2002. Only patients with the definite diagnosis of ESs or PNESs were analyzed (n = 85). Patients completed an epilepsy-specific quality-of-life instrument (QOLIE-89), the Profile of Mood States (POMS), and Adverse Events Profile (AEP). We used t tests and regression analyses to contrast HRQOL in PNESs and ESs and to elucidate the main factors associated with HRQOL in patients with PNESs.

RESULTS

In our sample, 45 patients had PNESs, and 40 had ESs. The overall HRQOL and scores on 13 of 19 QOLIE-89 subscales were significantly lower (i.e., worse) in PNES than in ES patients. AEP and scores on five of six POMS subscales also were worse in PNES patients than in ES patients. PNES versus ES diagnosis, POMS depression/dejection, and AEP were significant predictors of HRQOL, jointly explaining 65% variation in HRQOL. The lower HRQOL in PNESs versus ESs was in part explained by depression and AEP.

CONCLUSIONS

Patients with PNESs have a lower HRQOL and worse mood problems than do patients with ESs. This disadvantage is primarily due to depression and medication side effects, although these factors influence QOL in much the same way in PNES and ES patients. These baseline HRQOL data on patients with PNESs can be used to evaluate the effects of treatment in this patient population.

The relative health related quality of life of veterans with Parkinson's disease

OBJECTIVES

To use databases of the US Veterans Health Administration (VHA) to describe the impact of Parkinson's disease on health related quality of life (HRQoL) of veterans; to compare the HRQoL of veterans with Parkinson's disease with that of veterans reporting eight other neurological or chronic conditions; and to estimate the unique effect of Parkinson's disease on HRQoL.

METHODS

Respondents to the VHA 1999 large national health survey of veteran enrollees with a diagnosis of Parkinson's disease in VHA treatment files for the fiscal years 1997-1999 were identified by merging databases. The survey incorporated the Veterans SF-36, a well validated generic measure of HRQoL and functional status. This was used to compare patient groups. Mean physical (PCS) and mental (MCS) component summary scores were calculated for Parkinson's disease and eight other diseases by multivariable regressions that adjusted for age, sex, race, education, and 15 mental and physical co-morbid conditions that were self reported in the survey.

RESULTS

Of 887 775 survey respondents, 14 530 (1.64%) had a Parkinson's disease diagnosis. Controlling for sociodemographic factors and co-morbidities, veterans with Parkinson's disease had PCS and MCS below veterans with angina/coronary heart disease, arthritis, chronic low back pain, congestive heart failure, diabetes, and stroke. Veterans with spinal cord injury reported slightly lower PCS than veterans with Parkinson's disease (32.38 v 32.72; 0.03 of 1 SD). Veterans with depression reported markedly lower MCS than veterans with Parkinson's disease (35.94 v 41.48; 0.55 of 1 SD). The unique effect of having Parkinson's disease on HRQoL was to lower PCS and MCS by 4.10 and 3.42 points (0.41 and 0.34 of 1 SD), respectively.

CONCLUSIONS

The analysis quantifies the negative impact of Parkinson's disease on HRQoL, after controlling for sociodemographic factors and co-morbidities. Compared with eight other chronic conditions, Parkinson's disease imposes a relatively heavy burden on US veterans in the VHA health care system.

Quality of life as a concept for developing learning disability nursing practice?

This paper offers a critical examination of how the concept of Quality of Life might be used to enhance learning disability nursing practice. Quality of Life will increasingly influence the provision and evaluation of services and practice in the field of learning disability. Attempting to define and assess Quality of Life is, however, problematic because of the complexity and multidimensional nature of the concept. The use of domains to measure Quality of Life is advocated by many researchers for both objective and subjective measures and use of Quality of Life as an evaluation tool is seen as a way of improving the life quality of people with learning disabilities. However, there are concerns that the use of such an approach could perpetuate professional agendas rather than empower people with learning disabilities themselves. To date, Quality of Life approaches have not had a major impact on learning disability nursing. However, it is suggested that they can be helpful as sensitizing concepts, a basis for collaborative care planning and a framework for evaluation. Recommendations are made for education, practice and research.

HALYS and QALYS and DALYS, Oh My: similarities and differences in summary measures of population Health

Health-adjusted life years (HALYs) are population health measures permitting morbidity and mortality to be simultaneously described within a single number. They are useful for overall estimates of burden of disease, comparisons of the relative impact of specific illnesses and conditions on communities, and in economic analyses. Quality-adjusted life years (QALYs) and disability-adjusted life years (DALYs) are types of HALYs whose original purposes were at variance. Their growing importance and the varied uptake of the methodology by different U.S. and international entities makes it useful to understand their differences as well as their similarities. A brief history of both measures is presented and methods for calculating them are reviewed. Methodological and ethical issues that have been raised in association with HALYs more generally are presented. Finally, we raise concerns about the practice of using different types of HALYs within different decision-making contexts and urge action that builds and clarifies this useful measurement field.

Selecting human health metrics for environmental decision-support tools

Environmental decision-support tools often predict a multitude of different human health effects due to environmental stressors. The accounting and aggregating of these morbidity and mortality outcomes is key to support decision making and can be accomplished by different methods that we call human health metrics. This article attempts to answer two questions: Does it matter which metric is chosen? and What are the relevant characteristics of these metrics in environmental applications? Three metrics (quality adjusted life years (QALYs), disability adjusted life years (DALYs), and willingness to pay (WTP)) have been applied to the same diverse set of health effects due to environmental impacts. In this example, the choice of metric mattered for the ranking of these environmental impacts and it was found for this example that WTP was dominated by mortality outcomes. Further, QALYs and DALYs are sensitive to mild illnesses that affect large numbers of people and the severity of these mild illnesses are difficult to assess. Eight guiding questions are provided in order to help select human health metrics for environmental decision-support tools. Since health metrics tend to follow the paradigm of utility maximization, these metrics may be supplemented with a semi-quantitative discussion of distributional and ethical aspects. Finally, the magnitude of age-dependent disutility due to mortality for both monetary and nonmonetary metrics may bear the largest practical relevance for future research.

Regional differences in functional status among the aged

This study investigated regional differences in functional status among aged Medicare beneficiaries in the United States, and the degree to which population risk factors and certain geographic/environmental attributes of communities accounted for the regional differences. Four years of the Medicare Current Beneficiary Survey (1992-1995) were pooled together yielding 37,150 person-year observations of functional status for a sample of aged Medicare beneficiaries residing in the community or nursing homes. Multinomial logit models, estimated on a four-category functional status scale, produced strong empirical evidence of substantial regional differences in the prevalence of functional independence, functional limitations, IADL limitations, and ADL limitations, that could not be attributed to regional population composition, socio-demographic factors, lifestyle characteristics, and chronic medical conditions. Although such population risk factors accounted for much of the regional variations in functional status among older men, the notably higher prevalence of IADL and ADL limitations among older women residing in the Deep South could not be similarly attributed to such risk factors. Rather, the empirical results suggest that a significant portion of the harmful effects associated with residence in the Deep South among older women may be attributed to a higher prevalence of residence in counties characterized by lower population density and/or higher poverty concentration.

"Are you better?" A qualitative study of the meaning of recovery

PURPOSE

Research into the meaning of illness has often focused on an individual's transition into a state of being ill, for example the adoption of a sick role. The question "Are you better?" addresses the transition out of this state and is fundamental to the patient-clinician relationship, guiding decisions about treatment. However, the question assumes that all patients have the same meaning for "being better." The purpose of this study was to explore the meaning of the concept of recovery (getting better) in a group of people with upper limb musculoskeletal disorders.

METHODS

Qualitative (grounded theory) methods were used. Individual interviews were conducted with 24 workers with work-related musculoskeletal disorders of the upper limb. The audiotaped interviews were transcribed and coded for content. Categories were linked, comparisons made, and a theory built about how people respond to the question "Are you better?"

RESULTS

The perception of "being better" is highly contextualized in the experience of the individual. Being better is not only reflected in changes in the state of the disorder (resolution) but could be an adjustment of life to work around the disorder (readjustment) or an adaptation to living with the disorder (redefinition). The experience of the disorder can be influenced by factors such as the perceived legitimacy of the disorder, the comparators used to define health and illness, and coping styles, which in turn can influence being better.

CONCLUSION

Two patients could mean very different things when saying that they are better. Some may not actually have a change in disease state as measured by symptoms, impairments, or function.

Future states: the axioms underlying prospective, future-oriented, health planning instruments

Proscriptive planning exercises are critical to and generally accepted as integral to health planning at varying scales. These require specific instruments designed to predict future actions on the basis of present knowledge. At the macro-level of health economics, for example, a number of future-oriented Quality of Life Instruments (QL) are commonly employed. At the level of individual decision making, on the other hand, Advance Directives (AD's) are advanced as a means by which healthy individuals can assure their wishes will be carried out if at some future point they are incapacitated. As proscriptive tools, both instrument classes appear to share an axiomatic set whose individual parts have not been rigorously considered. This paper attempts to first identify and then consider a set of five axioms underlying future oriented health planning instruments. These axioms are then critiqued using data from a pre-test survey designed specifically to address their assumptions. Results appear to challenge the validity of the axioms underlying the proscriptive planning instruments.
