Quality-of-life measurement in advanced cancer: assessing the individual

The experience of using the SEIQoL-DW with patients with advanced chronic obstructive pulmonary disease (COPD): issues of process and outcome

PURPOSE

To report the experience of using the SEIQoL-DW for the measurement of quality of life with patients with advanced COPD and consider its feasibility, acceptability and appropriateness for a Phase III randomised controlled trial (RCT).

METHODS

The SEIQoL-DW was administered according to its instructions within a Phase II RCT 3-5 times per patient, across 13 patients and the process audio-recorded. Quantitative and qualitative criteria were used to assess feasibility, acceptability and appropriateness. Qualitative analysis of the transcripts and fieldwork notes was conducted using Framework Analysis.

RESULTS

The SEIQoL-DW steps (of identifying five quality of life cues, rating their functioning and importance) were completed at 48/51 interviews. However, some respondents were overwhelmed by the scripted introduction, experienced difficulty with cue identification, and focused only on certain types of cues (Step 1); some had difficulty interpreting and rating the concept of Step 2; and some had difficulty interpreting 'importance' and manipulating the SEIQoL-DW disc (Step 3).

CONCLUSIONS

Patients with advanced COPD were able to complete the SEIQoL-DW but analysis of its administration identified practical and conceptual concerns which question the validity of the results obtained. Suggestions for the development of the SEIQoL-DW and future feasibility studies are given.

Somatically ill persons' self-nominated quality of life domains: review of the literature and guidelines for future studies

OBJECTIVE

To review which domains somatically ill persons nominate as constituting their QoL. Specific objective is to examine whether the method of enquiry affect these domains.

METHODS

We conducted two literature searches in the databases PubMed/Medline, CINAHL and Psychinfo for qualitative studies examining patients' self-defined QoL domains using (1) SEIQoL and (2) study-specific questions. For each database, two researchers independently assessed the eligibility of the retrieved abstracts and three researchers subsequently classified all QoL domains.

RESULTS

Thirty-six eligible papers were identified: 27 studies using the SEIQoL, and nine presenting data derived from study-specific questions. The influence of the method of enquiry on patients' self-nominated QoL domains appears limited: most domains were presented in both types of studies, albeit with different frequencies.

CONCLUSIONS

This review provides a comprehensive overview of somatically ill persons' self-nominated QoL domains. However, limitations inherent to reviewing qualitative studies (e.g., the varying level of abstraction of patients' self-defined QoL domains), limitations of the included studies and limitations inherent to the review process, hinder cross-study comparisons. Therefore, we provide guidelines to address shortcomings of qualitative reports amenable to improvement and to stimulate further improvement of conducting and reporting qualitative research aimed at exploring respondents' self-nominated QoL domains.

Evaluation of quality-of-life measures for use in palliative care: a systematic review

PURPOSE

In this literature review we evaluated the feasibility and clinimetric quality of quality-of-life (QoL) measurement instruments suitable for use in palliative care.

METHODS

We conducted a systematic literature review to identify instruments measuring (at least one domain of) QoL. We selected articles that present data on patients receiving palliative care and at least one measurement property. A checklist was used to describe the characteristics of the instruments, and a widely accepted rating list was used to evaluate the clinimetric aspects.

RESULTS

29 instruments were identified and evaluated, most of which were targeted at palliative patients in general. None of the instruments demonstrated satisfactory results for all measurement properties. Fourteen instruments received positive ratings for construct validity. Thirteen instruments were tested for reliability, but only two were tested adequately and had positive results (ICC>0.70). Responsiveness was not tested adequately for any of the instruments. Very few of the studies provided information on the interpretation of the scores. Overall, the MQOL, followed by the QUAL-E and the QODD, received the best ratings for their measurement properties.

CONCLUSIONS

Many measurement instruments were identified, but most had not yet been adequately evaluated. The evaluation of existing instruments with good content validity should have priority over the development of new instruments.

Patients' understanding of the concepts of health and quality of life

OBJECTIVE

The aim of this study was to identify how persons' with rheumatoid arthritis (RA) understand the concepts of health and quality of life (QoL).

METHODS

A phenomenograpic approach was used to gauge variations in understanding of health and QoL. Semistructured interviews were conducted with 22 persons having RA. The interviews were audiotaped, transcribed verbatim, and analyzed, resulting in a descriptive system consisting of categories and subcategories.

RESULTS

Health was primarily associated with being healthy/being free from disease, being able to function normally, experiencing well-being, and having a healthy lifestyle. Two above-mentioned domains, "being healthy" and "being able to function normally" overlapped with respondents' understanding of QoL. Additional perceived domains included attitudes towards life and, social and physical environments.

CONCLUSION

The results show that patients' understanding of the two concepts of health and QoL partially overlap and partially differ.

PRACTICE IMPLICATIONS

Patients' understanding of the concepts is individual and diverse, which needs to be taken into account in patient-physician consultations to ensure good communication. Furthermore, the interpretation of results based on patient-reported outcomes instruments measuring health status and/or QoL needs to be further studied over time to identify possible changes in these conceptions.

Factors associated with lower quality of life among patients receiving palliative care

AIM

This paper is a report of a study conducted to (1) assess the quality of life (QoL) and physical functioning status of patients diagnosed with advanced cancer and receiving palliative care; (2) determine if there was a statistically significant relationship between their physical functioning and QoL and (3) identify the demographic and disease-related variables related to their QoL.

BACKGROUND

Achieving the best possible QoL is a major goal in palliative care. However, research findings about the relationship between QoL and demographic variables have been inconsistent.

METHOD

Three hundred patients with advanced cancer were recruited from four district hospitals in Hong Kong between February 2005 and July 2006. Their QoL and physical functioning status were assessed by face-to-face interview, using the McGill Quality of Life Questionnaire (Hong Kong version) and the Palliative Performance Scale respectively.

RESULTS

Participants reported reduced ambulation, inability to perform hobbies or housework, and the need for occasional assistance in self-care (mean: 64.6 out of 100, sd: 19.3, range: 20-100). QoL was fair (mean: 6.2 out of 10, sd: 1.5, range: 0.9-10). There was a weak positive association between physical functioning and QoL scores. Multiple regression analysis showed that patients who were older, female, had ever been married, or had higher physical functioning tended to have better QoL.

CONCLUSION

More could be done in symptom and psychosocial management to improve patients' QoL, in particular for those who are younger, male or single, or who have lower physical functioning.

Usefulness of chemotherapy beyond the second line for metastatic breast cancer: a therapeutic challenge

PURPOSE

Several lines of chemotherapy can be proposed for patients with metastatic breast cancer, but beyond the second line, agreement is lacking concerning the most appropriate therapeutic strategy.

METHODS

We conducted a retrospective analysis of the files of 162 patients, who had received at least 3 lines of chemotherapy (CT3) for metastatic breast cancer during a 5-year period (2000-2004), in order to analyze management practices and search for factors affecting survival from CT3 and predictive factors of non-progressive disease (NPD) after CT3.

RESULTS

Multivariate analysis identified seven factors which had a positive influence on survival from CT3 (SBR grade I, absence of adjuvant hormone therapy, free interval >or=2 years, absence of cerebromeningeal metastasis before CT, unique focus at initiation of CT3, use of polychemotherapy for CT2, and complete response to CT1 or CT2) and two predictive factors of NPD (histology and drug group used for CT3).

CONCLUSIONS

These factors should help determine the appropriate strategy for proposing a third line of chemotherapy.

Palliative day care--a study of well-being and health-related quality of life

AIM

The aim of the study was to study the outcomes of palliative day care, in terms of health-related quality of life and the emotional well-being of cancer patients participating in a palliative day care programme for a period of five weeks, compared with a group of palliative cancer patients not participating in day-care.

METHODS

The day care sample comprised of patients in a palliative day care programme delivered in two different day care facilities. Participants in the comparison group were recruited from a palliative home care service facility. All patients had a cancer diagnosis. The participants were invited to respond to two questionnaires once a week for a period of five weeks; the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-30) and the Mood Adjective List (MACL).

RESULTS

The participants in the day care group and the comparison group reported similar levels of perceived functioning and symptoms, as measured by the EORTC QLQ-30, with no significant differences between the groups. However, the day care group reported higher levels of emotional well-being as measured by the MACL than the comparison group reported, although these differences were not statistically significant.

Individual quality of life in chronic kidney disease: influence of age and dialysis modality

BACKGROUND AND OBJECTIVES

Novel individualized quality-of-life (IQOL) measures permit patients with chronic kidney disease (CKD) to nominate unique areas of their lives that contribute to their well-being. This study assessed for differences in domains nominated by patients with CKD. We also examined the strength of association between (1) multidimensional health-related quality-of-life measures and IQOL and (2) psychosocial factors and IQOL.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We performed a cross-sectional study of 151 patients who were undergoing peritoneal dialysis or hemodialysis or had stages 4 through 5 CKD. Patients completed the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQOL-DW), an instrument that assesses IQOL on the basis of patient-identified domains. Patients also completed health-related quality-of-life and psychosocial health measures.

RESULTS

Patients with CKD nominated many domains on the SEIQOL-DW, but family and health were the most common for all groups. Kidney disease was listed more frequently by peritoneal dialysis compared with hemodialysis patients or patients with CKD (31 versus 14 versus 5%, respectively). There were no significant differences in SEIQOL-DW scores between subgroups. SEIQOL-DW scores correlated with mental well-being and inversely correlated with chronic stress and depression.

CONCLUSIONS

Patients with advanced CKD demonstrate compromised quality-of-life scores comparable to dialysis patients. IQOL measures provide unique information that may help guide interventions that are better tailored to address patients' concerns about their well-being. These findings also suggest that renal clinics should have staff available to address psychosocial aspects of patient well-being.

[Evaluation of units for short-term terminal care in nursing homes]

The Units for short-term terminal care in 10 nursing homes were evaluated in terms of (a) meeting minimum care requirements for organisation, personnel and expertise and (b) changes in outcomes in patients. Interview with staff members show that 69% of the care requirements were met. Requirements for expertise development were better met (77%), and requirements for personnel and team were met less well (58%). The studies on patient outcomes show that the patients' functional status decreased as death approached, but symptoms did not decrease with similar rates. In addition, quality of life remained stable. We conclude that the minimum care requirements should be revised, taken into account the way the requirements are used in daily practise. The data seem to point at good quality of care. We advise a repetition of the last evaluation in 2003.

Shared decision making and serious mental illness

This study examined medication decision making by 84 persons with serious mental illness, specifically examining relationships among perceived coercion, decisional capacity, preferences for involvement and actual participation, and the outcomes of medication adherence and quality of life (QoL). Multiple and logistic regression analysis were used in this cross-sectional, descriptive study, controlling for demographic, socioeconomic, and utilization variables. Appreciation was positively related to medication adherence behaviors for the past 6 months. Women, older individuals, and those living independently were more likely to have taken all their medications over the past 6 months. Neither client participation, preference, nor preference-participation agreement was found to be associated with better medication adherence or QoL.

Individual quality of life: adaptive conjoint analysis as an alternative for direct weighting?

In the schedule for the evaluation of individual quality of life (SEIQoL) the weights for five individualized quality of life domains have been derived by judgment analysis and direct weighting (DW). We studied the feasibility and validity of adaptive conjoint analysis (ACA) as an alternative method to derive weights in 27 cancer patients and 20 patients with rheumatoid arthritis. Further, we assessed the convergence between direct weights and weights derived by ACA, and their correlation with global quality-of-life scores. All respondents finished the ACA task, but one in five respondents were upset about the ACA task. Further, the task was vulnerable to judgment ‘errors’, such as inconsistent answers. The agreement between the two weights was low. Both weighted index scores were strongly correlated to the unweighted index score. The relationships between the index score and scores on a visual analogue scale for global individual quality of life and global quality of life were similar whether or not the index score was calculated with DW weights, with ACA weights, or without using weights. We conclude that, because weights did not improve the correlation between the index score and global quality of life scores, it seems sufficient to use the unweighted index score as a measure for global individual quality of life.

Proxy assessment of quality of life in patients with prostate cancer: how accurate are partners and urologists?

OBJECTIVES

To assess the ability of partners and clinicians to make proxy judgements on behalf of patients with prostate cancer relating to selection of life priorities and quality of life (QoL).

DESIGN

47 consecutive patients with histologically proven adenocarcinoma, and their partners, were recruited. The partners were asked to assess, by proxy, the QoL of the patient by completion of a series of interview-led questionnaires assessing global QoL (SEIQoL-DW), health-related QoL (FACT-P) and overall QoL (visual analogue score [VAS]). The patients' clinicians were asked to complete the SEIQoL-DW and VAS by proxy as soon as possible after a consultation with the patient.

SETTING

Patients with histologically proven adenocarcinoma, their partners and their clinicians.

MAIN OUTCOME MEASURES

Proxy scores for SEIQoL-DW, FACT-P and VAS, as provided by partners and clinicians.

RESULTS

25 partners made a proxy assessment of the patients. The results showed that partners were able to select similar QoL cues to those of the patients (Spearman-Rank correlation 0.89). Comparison of the QoL scores obtained from patients and partners in proxy using the questionnaires showed no statistically significant difference (paired t-test). Urologists were poor predictors of areas of life (cues) that were important to their patients. The doctors overemphasized the importance of survival, postoperative complications, urinary symptoms, sexual ability, activities of daily living and finance, but underestimated the importance of wife, family, home and religion. Comparison of the QoL scores obtained from patients and urologists by proxy showed a significantly lower score when assessed by urologists using the SEIQoL-DW questionnaire.

CONCLUSIONS

Partners are able to accurately assess, by proxy, the areas of life that are of importance to patients. Clinicians, however, who are charged with making decisions on behalf of patients, are very poor judges of their patients' life priorities and QoL. This illustrates that conventional views held by most doctors regarding the priorities patients set themselves when planning treatment should be called into question and consequently suggests that the way in which doctors and patients arrive at treatment decisions must be reviewed.

Depression and quality of life in patients with amyotrophic lateral sclerosis

INTRODUCTION

There is increasing debate on the issue of whether to facilitate the end-of-life decisions of severely disabled patients with diseases such as amyotrophic lateral sclerosis (ALS). Our two studies were intended to explore the emotional state and quality of life of patients with ALS.

METHODS

Two studies were performed to investigate depression and the quality of life in ALS patients: one was a longitudinal study, the other a comparison of ALS patients to normal control subjects.

RESULTS

These studies found no correlation between physical disability in ALS and either depression or the quality of life. The severity of depression was found to be inversely related to educational status. In ALS patients the quality of life was comparable with healthy controls.

DISCUSSION

The rationale for not providing life-sustaining treatment to severely disabled patients is that a poor quality of life is expected after such treatment. Our studies have shown, however, that ALS patients can experience a satisfactory quality of life without depressive manifestations even if they are severely physically impaired, including in the terminal phase.

Methodological issues related to assessing and measuring quality of life in patients with cancer: implications for patient care

Consideration of quality-of-life issues by all members of the healthcare team is essential in caring for people with cancer. In cancer research, quality of life is generally classified as health-related quality of life or individual quality of life. This paper discusses the instruments used to measure quality-of-life outcomes, and the relevance of such findings for healthcare staff in planning and providing effective and patient-centred care. Visual analogue scales (VASs) and questionnaires are commonly used to measure quality of life; however, both types of instruments are criticized because the content may not be relevant to individual patients, and do not distinguish differences between statistical and clinical significances in the findings. Using a combination of questionnaires and VASs may overcome some of these criticisms. In order to interpret the difference between statistical and clinical significance of findings and the associated implications for patient care, a mixed-methods approach to data collection is recommended in quality-of-life studies. This provides meaning and understanding to the quantitative data and individual perspectives on patients' experiences of having cancer. Information from such studies may also be more effective in helping healthcare staff identify relevant issues when planning cancer care services at individual, local and national level.

Quality of life before and one year following stem cell transplantation using an individualized and a standardized instrument

OBJECTIVE

The aim was to prospectively measure quality of life in patients with malignant blood disorders following stem cell transplantation (SCT) using an individualized and a standardized measure.

METHODS

Twenty-two consecutive patients were assessed before and one year following SCT, using a generic and disease-related version of the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) and the EORTC QLQ-C30. Results of the QLQ-C30 were compared with Swedish norm values.

RESULTS

A majority of the patients reported concerns related to health before as well as one year after SCT, recorded by both instruments. Mean scores produced by the SEIQoL-DW, and four scales of the EORTC QLQ-C30, showed a change over time, indicating improved quality of life one year after SCT. In comparison with Swedish norm values for the EORTC QLQ-C30, SCT recipients reported a worse functioning.

CONCLUSIONS

In addition to well-known disease and treatment-related problems, areas not typically included in standardized instruments were nominated in the disease-related SEIQoL-DW. Such areas included positive aspects, e.g. a changed view of life and oneself. The results support the use of the generic and disease-related SEIQoL-DW to achieve a comprehensive picture of patient's clinical situation under treatment or when recovering from illness.

Quality of life in palliative care: being at ease in the here and now

Quality of Life (QoL) is an important issue for users of hospice services and may be assessed in a quantitative way. This study set out to evaluate the effectiveness of the Schedule for the Evaluation of Individual Quality of Life – Direct Weighting (SEIQoL-DW). A sequential mixed methods design was used to examine both quantitative and qualitative factors relating to quality of life. Five participants were recruited from an inpatient specialist palliative care (hospice) unit in East Anglia. Each participant completed the SEIQoL-DW followed by unstructured interviews, which were analysed using Giorgi’s (1985) psychological phenomenological method.

It was found that SEIQoL-DW provided an opening or ‘window’ onto participants’ QoL as they travelled from their past to their future. Themes emerging from the unstructured interviews suggest that QoL was about ‘being at ease’ in the ‘here and now’ and was influenced by past experiences and future expectations. Existential and spiritual issues, which were not all captured by the SEIQoL-DW, were of more importance than physical symptoms. This needs to be taken into account when caring for those nearing the end of their lives and particularly when using medications that have an adverse effect on mental acuity.

Health state utilities: a framework for studying the gap between the imagined and the real

OBJECTIVES

Health state utilities play an important role in decision analysis and cost-utility analysis. The question whose utilities to use at various levels of health-care decision-making has been subject of considerable debate. The observation that patients often value their own health, but also other health states, higher than members of the general public raises the question what underlies such differences? Is it an artifact of the valuation methods? Is it adaptation versus poor anticipated adaptation? This article describes a framework for the understanding and study of potential mechanisms that play a role in health state valuation. It aims at connecting research from within different fields so that cross-fertilization of ideas may occur.

METHODS

The framework is based on stimulus response models from social judgment theory. For each phase, from stimulus, through information interpretation and integration, to judgment, and, finally, to response, we provide evidence of factors and processes that may lead to different utilities in patients and healthy subjects.

RESULTS

Examples of factors and processes described are the lack of scope of scenarios in the stimulus phase, and appraisal processes and framing effects in the information interpretation phase. Factors that play a role in the judgment phase are, for example, heuristics and biases, adaptation, and comparison processes. Some mechanisms related to the response phase are end aversion bias, probability distortion, and noncompensatory decision-making.

CONCLUSIONS

The framework serves to explain many of the differences in valuations between respondent groups. We discuss some of the findings as they relate to the field of response shift research. We propose issues for discussion in the field, and suggestions for improvement of the process of utility assessment.

Change in what matters to palliative patients: eliciting information about adaptation with SEIQoL-DW

This study was carried out to investigate the usefulness of the SEIQoL-DW to elicit information about response shifts in palliative patients. The instrument measures individual quality of life and allows respondents to choose, rate and weight important areas of life (cues). We explored patients' reconceptualizations (ie, change in cues) and their value change (ie, change of cues weights). Results of 21 patients showed what mattered to these patients and how they had adjusted to deteriorating health. There is a risk that repeated measurements do not provide all the information that is potentially present and relevant to explore response shifts. But clear instructions to interviewers, such as careful listening, probing self-evident cues such as health and family, and accurate recording of cues on the forms may overcome this risk. Future research is recommended to explore the possibilities of regular assessments to facilitate better adjustment of patients.

Making them more vulnerable: nursing insights on the irony of using questionnaires

TOPIC

Nursing insights on the experience of using standardized questionnaires during hospice care.

PURPOSE

To explore and describe the experience of hospice staff using questionnaires on hospice clients: whether such instruments help or hinder the holistic, compassionate hospice practice and to set this topic on the research agenda in the hope of generating critical reflection on this important aspect of hospice care.

SOURCES

A cross-section of hospice staff interviewed about their experience with administering the questionnaires. (Findings from research conducted with hospice clients on their experience of questionnaires are published separately.)

CONCLUSIONS

The initial findings indicate that staff perceive questionnaires as negatively impacting on their efforts to engage in holistic and compassionate hospice practice and point to a major irony that questionnaires, designed for the supportive care of the vulnerable, actually make the vulnerable more vulnerable.

The Prognostic Value of Measuring Health-Related Quality of Life in Hospice Patients

PURPOSE

Better prognostic instruments are sorely needed for patients near the end of life. Health-related quality of life instruments designed for hospice patients have not been previously studied for their prognostic properties. This study evaluated the prognostic property of the Missoula-Vitas Quality of Life Index (MVQOLI) with hospice patients.

METHODS

A prospective, cross-sectional cohort design included all consecutive patients admitted to a hospice over a 19-month period. At admission to hospice, patients were asked to complete an MVQOLI. In addition, hospice nurses completed three functional status instruments. All patients were followed until death, study closure, or loss to follow-up.

RESULTS

The sample included 1047 patients, but only 231 (22%) were able to complete an MVQOLI at admission. Functional status data were collected on nearly all of the patients. The Karnofsky performance score, modified activity of daily living score, and descriptive symptom score were significantly associated with survival time. Using Cox regression models these functional status assessments were strongly associated with survival time (p<0.001). However, the MVQOLI scores were not significantly associated with survival time, except for the function subscale (p=0.045).

CONCLUSION

The MVQOLI global, total, and four of the five weighted-domain baseline scores were not associated with survival time in hospice patients. Other methods for prognostication at the end of life are needed.

Objective physical activity and self-reported quality of life in patients receiving palliative chemotherapy

There is little objective data on how cancer and its therapy affect physical activity. The main aims of this pilot study were 1) to compare physical activity in patients receiving palliative chemotherapy and healthy controls, and 2) to explore the relationship between patients' activity, quality of life (QoL), and clinical performance status. A miniaturized electronic meter objectively recorded activity for one week in 20 patients with upper gastrointestinal cancer receiving palliative chemotherapy and in 13 age-matched healthy controls. Patients also completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F; fatigue), and Functional Assessment of Anorexia and Cachexia Therapy (FAACT; anorexia/cachexia) quality-of-life questionnaires. The patients' median estimated total energy expenditure was 8% lower (P=0.0003), median time spent upright was approximately two hours/day less (P=0.0002), and median steps taken/day was 43% lower (P=0.002) than that of the control group. Neither estimated energy expenditure nor average steps taken/day correlated significantly with EORTC QLQ-C30 physical functioning, fatigue, or global health status/QoL. There was no correlation with the FAACT "Trial Outcome Index" (TOI), but the FACIT-F TOI and both estimated energy expenditure and the average steps taken/day correlated significantly (r=0.59, P=0.009 and r=0.59, P=0.008). It is concluded that patients receiving palliative chemotherapy were less active than healthy controls; however, the relationship between physical activity and QoL requires further characterization.

Patient Expectations of Quality of Life Following Lumbar Spinal Surgery

Spinal surgery is one of the most frequently performed surgeries in the United States. In 2003, almost 450,000 cases were performed for problems related to lumbar herniated disks, stenosis, and degenerative changes. It has been reported that patient expectations play a role in perceived quality of life (QOL). Because surgery is frequently a last resort for patients with spinal disease, patients often have high expectations of their outcomes of surgery. Patient expectations of surgical outcome may play an important role in recovery and perceived QOL. The research on patient expectations of surgery in the spinal surgery literature is limited. This study examined the relationships between perceived QOL, expectations, and level of optimism. A sample of 57 patients completed questionnaires designed to measure perceived QOL, expectations, and optimism before lumbar spinal surgery and 3 months after surgery. The major findings of the study are as follows: (a) patients with higher degrees of optimism reported better perceived QOL; (b) increased fulfillment of expectations was associated with better postoperative QOL; and (c) both expectations and level of optimism were significant predictors of postoperative QOL. These findings will help nurses better understand how patients' expectations can affect their perceived QOL while recovering from lumbar spinal surgery.

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.

Changes in and correlates of individual quality of life in advanced cancer patients admitted to an academic unit for palliative care

Changes in individual quality of life (IQoL) and its correlates in patients admitted to an academic palliative care unit are reported. Correlates tested were pain, fatigue, and reconceptualization (changes in content of quality of life, a measure of adaptation). IQoL was measured with a structured interview method that derives an IQoL score from evaluations of individually nominated life areas. Twenty-nine patients were included in the study and interviewed shortly after unit admission. Sixteen patients were interviewed before discharge (more than 1 week between interviews). The results show that mean IQoL scores improved notably. Pain and IQoL correlated negatively and moderately at admission, and correlations between fatigue and pain at discharge and IQoL were negative and strong. An increasing number of changes in life areas was moderately associated with worsening IQoL. Life area's most often nominated were relationships with family members and friends, symptoms and aspects related to maintaining control.

Anxiety, depression and quality of life of cancer patients undergoing radiation therapy: a cross-sectional study in a community hospital outpatient centre

The purpose of the present study is to determine the impact of illness characteristics and psychopathological comorbidity on the quality of life (QoL) of radio-oncological patients in health-related and individual dimensions. Sixty-three of 93 eligible patients (40 women and 23 men) were included in the study during their radiation therapy visit to an outpatient centre annexed to a community hospital in Southern Bavaria, Germany. In a semi-structured interview, we elicited individually relevant life domains rated by the patients according to the 'Schedule for the Evaluation of Individual Quality of Life - Direct Weighting'. In addition, the participants completed the 'European Organization for Research and Treatment of Cancer (EORTC) QoL Questionnaire Core 30' and the 'Hospital Anxiety and Depression Scale'. We also assessed the demand for psychotherapy and utilization of psycho-oncological services. In total, 9.5% of the examined patients suffer from clinically relevant anxiety and/or depression [total Hospital Anxiety and Depression Scale (HADS) score >19]. There was a weak positive correlation between Karnofsky's Performance Status and QoL. Anxiety and depression were significantly correlated with impaired QoL, especially with impaired individual QoL. There was no association between psychopathological comorbidity and the requirement for psycho-oncological support. Conversely, patients who report difficulties in accepting help had a significantly lower QoL. Psychopathological comorbidity has a considerable influence on QoL of patients undergoing radiotherapy. Measuring the individual QoL appears as an adapted needs assessment and helps the psychotherapist in focusing on the patient's problems and desires. Furthermore, the patient's QoL is a main target in providing or planning mental health care in non-university oncological services.

Association of complementary methods with quality of life and life satisfaction in patients with gynecologic and breast malignancies

GOALS OF WORK

In gynecological oncology, there is growing interest in the use of complementary and alternative medicine (CAM) methods. The lack of data regarding side effects, the lack of any survival advantages, and the costs of these methods appear to have no influence on patients' decisions on whether to use CAM. Our interest was to evaluate the association between CAM use and the patients' quality of life/life satisfaction (QoL/LS).

MATERIALS AND METHODS

One thousand thirty women with breast cancer of gynecologic malignancies were asked to participate in this study, which included a questionnaire and a personal interview on CAM. User status was compared with the patient's own description of her QoL/LS and with the cancer type.

MAIN RESULTS

CAM was used by 48.7% of all women (n = 502). Breast cancer patients stated that they used CAM in 50.1% and women with gynecological cancer in 44.0%. The use of mistletoe was widespread (77.3%) and was more often seen in breast cancer patients than in gynecological cancer patients (74.4% vs 67.0%). CAM users less frequently stated an overall deterioration of their health status (35.1%) compared to nonusers (50.1%). CAM use resulted in a stated improvement in family conditions (6%) in comparison with the nonusers (2%).

CONCLUSIONS

With regard to patients' perception of health status, CAM use is associated with a better coping with their disease. Most other categories of LS are not affected by CAM use. Patient-oriented information comparing standard therapies with CAM methods should be made widely available, and patients' expectations of CAM use should be discussed between the physician and the patient.

What Happens to People after Malignant Cord Compression? Survival, Function, Quality of Life, Emotional Well-being and Place of Care 1 Month after Diagnosis

AIMS

To present further findings from the Scottish Cord Compression Study, in which the diagnosis, management and outcome of 319 patients with a definitive diagnosis of malignant cord compression (MCC) were examined.

MATERIALS AND METHODS

In total, 256 (80%) patients in the study consented to be interviewed shortly after diagnosis and at follow-up interviews. One hundred and twenty-eight patients were interviewed 1 month after diagnosis (40% of the total; 57% [128/224] of patients alive 1 month after diagnosis; 68% [128/188] of patients who also consented to follow-up). Survival data of the whole MCC population and data from interviewing 128 patients 1 month after diagnosis are presented.

RESULTS

The median survival of all patients was 59 days (95% confidence interval [CI] 43-75 days). The median Karnofsky performance status was 50 (interquartile range 40-60), indicating a need for considerable nursing and medical care, and was poorest for patients with lung cancer (median 40; interquartile range 30-60). The place of care was dependent on mobility at diagnosis; patients walking at diagnosis were more likely to be at home, whereas patient requiring assistance or who were unable to walk were more likely to be in institutional care (P = 0.019). Mobility and bladder function were determined by mobility and bladder function at diagnosis (P < 0.001). Of those unable to walk at diagnosis, 7% regained full mobility. Of those catheterised at presentation, 28% regained full bladder function. Forty-seven per cent (56/120, 95% CI 40-54) of patients interviewed were in pain despite oncological treatment and 18% (22/ 120; 95% CI 8-19) reported the pain as severe (visual analogue scale > 7). The median quality-of-life (Schedule for Evaluation of Individualised Quality of Life) score was 72/100, and was higher in patients with a better performance status (P = 0.026). A minority of patients (8%) screened positive for anxiety and depression using the Hospital Anxiety and Depression scale.

CONCLUSIONS

Notwithstanding the difficulties in following up this group of patients, this paper reports valuable findings detailing the experience of patients with MCC 1 month after diagnosis and treatment.

Advances in How Clinical Nurses Can Evaluate and Improve Quality of Life for Individuals With Cancer

PURPOSE/OBJECTIVES

To describe advances in the ways that clinical nurses understand, assess, and work to improve quality of life (QOL) for individuals with cancer since the 1995 Oncology Nursing Society's State-of-the-Knowledge Conference on QOL.

DATA SOURCES

Published research and clinical articles.

DATA SYNTHESIS

The number of QOL assessment tools and methods for understanding QOL results has increased. However, scant literature has focused on how clinical oncology nurses evaluate QOL and the methods they use to affect QOL for individuals with cancer.

CONCLUSIONS

Based on the nurse-patient relationship, clinical nurses are able to assess QOL in individuals with cancer and intervene appropriately to improve QOL.

IMPLICATIONS FOR NURSING

Clinical nurses can involve individuals with cancer in rating their QOL to assist in providing high-quality care that is directed at positively affecting QOL.

[The need for autonomy in the process of care-conceptual framework and research perspectives]

The article reflects the difference between independence and self-determination or autonomy in care relations. We consider that independence is only a fiction even for people with no functional limitations. Compared with this are people in need of care always confronted with professional interventions in their daily life which limit their self-determination. Even if participation and therefore also autonomy are part of the goal setting process in care a hierarchy in the relation of professional nurses and client is hardly to neglect. Quality of care with methods of evidence based nursing has must always take into account the client's implicit knowledge and experience which we call the "internal" evidence. Only the respect of the internal evidence can reduce the structural hierarchy between nurse and client. The article exemplifies these general conditions in care with nurse-client communication and the challenges of quality of care and quality of life.

Patients’ subjective symptoms, quality of life and intake of food during the recovery period 3 and 12 months after upper gastrointestinal surgery

Few studies describe patients' quality of life and their experienced symptoms during the recovery period after having undergone upper gastrointestinal surgery at 3 and 12 months. The aims of this study were to explore patients' quality of life and symptoms preoperatively and at 3 and 12 months following upper gastrointestinal surgery and to describe and compare patients' experiences of appetite, food intake, weight changes, tiredness and sleeping patterns. A descriptive and comparative quantitative design was used. Three instruments were used: the Gastrointestinal Symptom Rating Scale, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and the Eating Dysfunction Scale. A questionnaire was used to investigate symptoms such as mood, appetite, sleep, activities and well-being. Twenty-four patients were included in the study. The major results were that anxiety levels and global health status decreased and that patients felt more disappointed after 12 months compared with after 3 months. Four patients at 3 months after surgery and eight patients at 12 months regained their weight compared with the situation before surgery. The contribution of nursing care activities focusing on the importance of food intake and the patients' current and historical medical records in relation to their health status should continue to be examined and researched over a longer period of time.

Head and neck cancer: To what extent can psychological factors explain differences between health-related quality of life and individual quality of life?

AIMS

To assess the extent to which individualised quality of life (QoL) was related to standardised health-related quality of life (HR-QoL), and to assess how much of the variation in each of these measures could be explained by psychological variables.

METHODS

Fifty-five patients with newly diagnosed head and neck cancer completed the following outcome measures: the Patient Generated Index (PGI), the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and the Short Form 12 version 2 (SF-12v2). Explanatory factors were measured with the following: the Illness Perceptions Questionnaire-Revised (IPQ-R), the Beliefs about Medicines Questionnaire (BMQ), the Hospital Anxiety and Depression Scale (HADS), and the Brief COPE (a shortened version of the COPE).

MAIN FINDINGS

Standardised and individualised QoL measures were correlated only partly. The PGI correlated only with EORTC QLQ-C30 domains of emotional and cognitive functioning and SF-12 domains of mental health, emotional role, social, and physical role. The underlying psychological factors explaining each of the three outcome measures were different.

CONCLUSIONS

Respondent-generated measures such as the PGI could be used as an adjunct to more standardised measures of HR-QoL clinically. This has implications for assessing the impact of head and neck cancer on individualised QoL and also for improving patients' outcome through interventions aimed at targeting underlying psychological factors.

Feasibility and validity of a computer administered version of SEIQoL-DW

Computer administrered QoL instruments are increasingly used to assess outcomes. Our aim was to assess the feasibility and validity of an electronic version of the SEIQoL-DW. Pharmacy students (n = 40; mean age 25; 92% women) were administrated both the touch screen and the paper-and-pen versions in a cross-over study. The majority of the students (65 %) preferred the computer version, while almost a third (27%) preferred the paper and pen version. There was no overall order effect and the SEOQoL-DW index mean scores differed with 1.2 between the two versions. Those respondents completing the computer version first had higher scores than those completing the computer version second. The ICC comparing the formats was 0.77 (CI: 0.57-0.88) and the limits of agreement method showed that 85% of the observations were within +/- 1-10 units. Most students (82%) judged their QoL as being equivalent to their SEIQoL-DW score. The computer version of the SEIQoL-DW seems to be feasible and acceptable and seems to be valid alternative to the paper and pen version. However, further validation studies in larger patient populations are needed.

Problems eliciting cues in SEIQoL-DW: quality of life areas in small-cell lung cancer patients

The Schedule of Individual Quality of Life - Direct Weighting (SEIQoL-DW) is an individualized approach in the measurement of quality of life in which patients can choose, value and weight five areas that they consider important for their quality of life. Although a number of studies have reported on the feasibility of the administration of the instrument, little is known about how patients choose and define these five areas, the so-called 'cues'. This article describes problems in the elicitation of cues experienced in a qualitative, exploratory study among small-cell lung cancer patients (n = 31) in the Netherlands. Cues originate from patient-interviewer interaction which is best described as an area of tension between the patient's answers and the instrument instructions. As a result, the interviewer may inadvertently introduce bias while attempting to elicit cues, ultimately affecting patients' SEIQoL-DW measures. In order to prevent possible unnoticed interviewer bias special attention should be paid to the interviewer behaviour. Methods to record the meaning of cues should be considered. More research is needed in order to investigate differences in nominating cues with and without the use of the prompt list.

Descriptive and prognostic value of patient-reported outcomes: the bortezomib experience in relapsed and refractory multiple myeloma

PURPOSE

Bortezomib, a boronic acid dipeptide, has been recently introduced as a new approach to treating multiple myeloma (MM). The goal of this work was to evaluate the added value of patient-reported outcomes (PRO) in the interpretation of bortezomib clinical trial outcomes.

PATIENTS AND METHODS

Two hundred two patients with relapsed, refractory MM were treated with bortezomib as part of the SUMMIT (Study of Uncontrolled Multiple Myeloma Managed with Proteasome Inhibition Therapy) study. Patients were administered the following four PRO measures at several time points: the European Organisation for Research and Treatment of Cancer (EORTC) core Quality of Life Questionnaire (QLQ-C30) and the myeloma-specific module (QLQ-MY24), the Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue scale, and the Functional Assessment of Cancer Therapy (FACT)/Gynecologic Oncology Group (GOG) Neurotoxicity (Ntx) scale. Minimal important difference (MID) thresholds were used to define patients as improved, stable, or worsened. A survival analysis was conducted to assess the predictive power of PRO data.

RESULTS

For the total population, there was a positive change between baseline and best end point. Consistent with the clinical responses, change in PRO scores showed statistically significant differences between response groups with PRO improvement in patients with complete response (CR) or partial response (PR), mostly stable scores in patients with minor response or no change, and deterioration in most scores for patients with progressive disease. Change in scores for neuropathy-related symptoms was reasonably stable. In contrast, fatigue scores significantly improved for patients with CR or PR. When various MID thresholds were applied, the proportion of improved patients exceeded 35% for several domains within all change group definitions. Moreover, survival analysis results demonstrated the additional prognostic information PRO data can provide to supplement clinical data.

CONCLUSION

This study demonstrated the complementary value for PRO assessments in further interpreting clinical response, the impact of adverse effects, and patient prognosis in clinical trials.

Individualized assessment of quality of life in idiopathic Parkinson's disease

The purpose of this study was to assess quality of life (QoL) of patients with idiopathic Parkinson's disease (IPD). The Parkinson's Disease Questionnaire (PDQ-39) was compared with an individualized QoL tool: the Schedule for Evaluation of Individual Quality of Life Direct Weighting (SEIQoL-DW). One hundred twenty-three patients underwent interviews using these tools, together with the Mini Mental State examination, Beck Depression Inventory, a qualitative pain assessment, and the Palliative Care Assessment tool (for symptoms). The SEIQoL-DW was well tolerated and demonstrated that QoL not only was broad and highly individualistic but also was determined more by psychosocial than physical issues. Of the 87 domains nominated by patients, the most common were family (87.8%), health (52.8%), leisure activities (36.6%), marriage (35%), and friends (30.9%). The SEIQoL index score was predicted by depression but not by disease stage. However, the PDQ-39 was predicted by disease stage, the number of symptoms, and depression. Direct comparison of the tools confirmed that the SEIQoL index score was predicted by the PDQ-39 domains of social support, cognitive impairment, and emotion. The use of the SEIQoL-DW challenges current thinking within IPD research regarding QoL and its assessment using the PDQ-39.

Management strategies for patients with amyotrophic lateral sclerosis from diagnosis through death

BACKGROUND

Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder that is inevitably fatal. There are no effective treatments to stop or reverse the natural course of the disease. The role of the physician is to provide comfort and optimize quality of life.

REVIEW SUMMARY

Management of patients with ALS is a process extending over months to years. It begins with breaking the news of the diagnosis and extends through the terminal phase. Medication may extend lifespan by a small amount. However, most efforts are centered around symptom management. Areas of importance include respiration, nutrition, secretions, communication, pseudobulbar affect, therapy and exercise, spasticity and cramps, pain, depression and suicide, spirituality and religion, cognitive changes, the development of advance directives, and care at the end of life. Multidisciplinary ALS clinics provide much-needed support for patients with ALS and their caregivers.

CONCLUSION

Although physicians cannot cure ALS or even halt progression, there is much that can be done to manage the physical and emotional symptoms, thereby maintaining or enhancing quality of life.

The SEIQoL and functional status: how do they relate?

Over recent years, an emphasis has emerged in the UK and international policy documents, over the involvement of people in the delivery of health care. However, evaluations of health services still largely rest on outcome measures that reflect professional concerns. As new health services are being developed, new patient-centred outcome measures are needed to evaluate them. This paper aims at exploring the possibility of individual quality of life as an outcome measure for health services. As a first step, it aims to elucidate the relationship of functional outcome measures to the Schedule for the Evaluation of Individual Quality of Life (SEIQoL) in groups of people whose age or medical diagnosis serve as the basis for health service design. Its objectives are to study the relation of SEIQoL scores and life areas to functional status in an older population and in a group of people with chronic obstructive pulmonary disease (COPD). Older people selected their health most frequently as one of the most important areas in their life (9.9%, vs. 8.6% for people with COPD) and were more satisfied with it (U = 2,512, p = 0.007). People's health status did not impact on the way they defined their quality of life, but on their level of satisfaction with discrete life areas. The weights attributed to health were significantly negatively correlated to people's overall quality of life score in the overall sample (rho = -0.34, p < 0.001). In the light of recent national and international policy documents advocating for the development of new, more person-centred health services, our results support the proposition of the authors of SEIQoL, that individual quality of life measures have the potential to bring a significant contribution to the evaluation of health services.

Individual and health-related quality of life assessment in amyotrophic lateral sclerosis patients and their caregivers

We performed a cross-sectional study aimed to address the quality of life (QoL) and putative associated variables in amyotrophic lateral sclerosis (ALS) patients and their respective caregivers, using both health-related (WHOQOL-BREF) and individual (SEIQoL-DW) QoL instruments. Further, we sought to investigate concordance within patient-caregiver pairs for ratings of respective QoL. Thirty-seven patient-caregiver pairs were included in the study. QoL was rated low by both patients and caregivers, and there was no significant difference between them on scores of overall QoL, even if caregivers showed higher scores on the physical and psychological WHOQOL-BREF domains compared to patients. No correlation could be found between QoL of both patients and caregivers and all the examined socio-demographic variables. Moreover, concordance between patients and respective caregivers was low for ratings of QoL, suggesting that their QoL is not necessarily interrelated, and that these couples do not actually represent a unique psychological entity. Interestingly, physical dysfunction, measured with the ALS-FRS, was not significantly correlated with caregivers' individual QoL scores. The most frequently nominated SEIQoL-DW cues were related to health (physical and psychological) and family for both patients and caregivers, and there was high agreement for the choice of areas important for subject's QoL. Interestingly, patients and caregivers who endorsed spirituality as a significant domain reported better QoL. Our study confirms that ALS has a negative impact on QoL in both patients and caregivers. However, caregivers who present lower QoL levels are not always those who have to look after the most physically or psychologically impaired patients. Major attention on QoL issues of both patients and caregivers, family status, and health perception, integrated with the medical evaluation, could lead to a better understanding of the problems related to the caregiving experience, and could help couples dealing with this life-threatening disease.

Quality of life as an endpoint in Phase I oncology clinical trials of novel chemotherapy drugs

This paper examines the rationale, utility and feasibility of including quality of life as an outcome measure in Phase I trials of new applications of chemotherapy drugs. Typically, Phase I trials in oncology are designed to assess safety and maximal tolerated dose; however, it is argued that when subjectively assessed, self perceived quality of life is as important as physical toxicity. The outcomes of studies that have applied quality-of-life assessment in Phase I trials are reviewed, and recommendations are made for future research based on both methodologic and practical considerations.
