Validation of the Edmonton Symptom Assessment Scale

BACKGROUND

The Edmonton Symptom Assessment Scale (ESAS) is a nine-item patient-rated symptom visual analogue scale developed for use in assessing the symptoms of patients receiving palliative care. The purpose of this study was to validate the ESAS in a different population of patients.

METHODS

In this prospective study, 240 patients with a diagnosis of cancer completed the ESAS, the Memorial Symptom Assessment Scale (MSAS), and the Functional Assessment Cancer Therapy (FACT) survey, and also had their Karnofsky performance status (KPS) assessed. An additional 42 patients participated in a test-retest study.

RESULTS

The ESAS "distress" score correlated most closely with physical symptom subscales in the FACT and the MSAS and with KPS. The ESAS individual item and summary scores showed good internal consistency and correlated appropriately with corresponding measures from the FACT and MSAS instruments. Individual items between the instruments correlated well. Pain ratings in the ESAS, MSAS, and FACT correlated best with the "worst-pain" item of the Brief Pain Inventory (BPI). Test-retest evaluation showed very good correlation at 2 days and a somewhat smaller but significant correlation at 1 week. A 30-mm visual analogue scale cutoff point did not uniformly distinguish severity of symptoms for different symptoms.

CONCLUSIONS

For this population, the ESAS was a valid instrument; test-retest validity was better at 2 days than at 1 week. The ESAS "distress" score tends to reflect physical well-being. The use of a 30-mm cutoff point on visual analogue scales to identify severe symptoms may not always apply to symptoms other than pain.

[Outcome quality of gerontopsychiatric day-clinic treatment: changes in life-satisfaction:]

OBJECTIVE

The variety of institutional treatments in psychiatry, as well as financial aspects make it necessary to evaluate these institutions for the quality of their medical care. At the Central Institute of Mental Health in Mannheim, the quality of treatment at the geronto-psychiatric day-clinic is assessed on the level of outcome quality.

METHOD

The patients are examined at admission, at discharge, half a year and one year after discharge. Psychopathology, activities of daily living, social situation and quality of life are assessed by means of standardized instruments.

RESULTS

Preliminary results show that at discharge, patients are less depressed, have achieved a higher level of social activities and contacts and that their quality of life improved in most domains. In some domains of quality of life improvement is highly correlated with the amelioration of depressive symptoms, in others not.

CONCLUSION

Whether these effects of treatment will last, has to be studied in follow-up examinations.

Recurrent headache, coping, and quality of life in children: a review

OBJECTIVES

To clarify the concepts of coping with pain and quality of life (QoL) and to present a literature review of the strategies that children with recurrent headaches use to cope with their pain, the impact of recurrent headaches on children's QoL, and the influence of personal and situational variables on headache, coping, and QoL in children.

METHODS

The literature search encompassed published articles that were found by means of a CD-ROM search of MEDLINE (1966 to December 1998) and PsycLIT (1974 to December 1998) and the snowball method.

RESULTS

In pediatric headache research, only three studies have been found in which children report the use of various coping strategies, and only two studies considered QoL. Demographic factors and psychological variables such as depression, anger, and anxiety influence headache prevalence. The impact of headache-related variables such as headache type, severity, perceived cause, and prior experience on QoL has only been studied in adults.

CONCLUSIONS

More research on coping and QoL is needed in pediatric headache. The conceptual model that is presented in this article may serve as a guide.

[Quality of life in the course of deinstitutionalisation-- part IV of the Berlin Deinstitutionalisation Study]

As part of the Berlin Deinstitutionalisation Study, quality of life was assessed in 142 patients at two points of time. Discharged patients were reassessed one year after discharge. Patients who stayed in hospital were reinterviewed 1 1/2-2 years after the initial assessment. Discharged patients had more leisure activities, more often a "good friend", and more frequent social contacts. They were less often victim of a crime within the last year. In a cross-sectional comparison, they were significantly more satisfied with their life than patients who were still in hospital. In the latter group, only satisfaction with mental health improved significantly between first and second interview. Discharged patients became significantly more satisfied with their life in general, with leisure activities, with accommodation, and with mental health between initial assessment and follow-up. The findings demonstrate an improvement of quality of life in long-term hospitalised patients after discharge.

SF-36 health survey: tests of data quality, scaling assumptions, and reliability in a community sample of Chinese Americans

BACKGROUND

Chinese Americans are one of the fastest growing ethnic groups in the United States; however, language and cultural obstacles have challenged health workers and policy makers seeking to understand the health status and needs of this population.

OBJECTIVES

This study is the first to use a large-scale probability design to evaluate the 36-item Short-Form Health Survey (SF-36) in a Chinese population (n = 1,501).

METHODS

Using the International Quality of Life Assessment Project protocols, we examine summated-rating scaling assumptions, item-internal consistency, item-discriminant validity, and reliability.

RESULTS

Similar to previous studies, our tests indicated that the SF-36 generally met minimum psychometric criteria with high reliability and satisfactory scaling success rates for most scales. However, the performance of the vitality and mental health scales was less satisfactory with regard to discriminant validity and scaling success rates. Notably, our results indicate that VT3 and VT4 ("feel worn out" and "tired", respectively) formed a separate "fatigue" cluster more highly correlated with the mental health scale. However, MH4 and MH5 ("downhearted and blue" [reverse coded] and "been a happy person") were more highly correlated with the vitality scale, suggesting that it may be more meaningful to reorganize the vitality and mental health items along the dimensions of well-being and distress.

CONCLUSIONS

These results are interpreted within a cultural framework; however, additional work is needed to better understand the relationship between vitality and mental health for Chinese Americans.

Loratadine/pseudoephedrine for nasal symptoms in seasonal allergic rhinitis: a double-blind, placebo-controlled study

In this double-blind, placebo-controlled, crossover, parallel study, we treated 20 adults who had seasonal allergic rhinitis with once-daily fixed-combination loratadine/pseudoephedrine sulfate to observe its effect on relieving symptoms, primarily nasal congestion. Acoustic rhinometry detected a trend toward improvement in nasal patency, although the difference between pre- and post-treatment measures was not statistically significant. Endoscopic inferior turbinate photography documented that treatment led to statistically significant reductions in the amount of nasal edema and nasal secretions. The results of a quality-of-life questionnaire suggested that treatment alleviated nasal and ocular symptoms of rhinoconjunctivitis. An analysis of subjective visual analog scale scores showed a trend toward improvement in most but not all nasal symptoms. We conclude that once-a-day fixed-combination loratadine/pseudoephedrine is effective in relieving nasal congestion in patients with seasonal allergic rhinitis.

[Schizophrenia and the quality of life]

This paper discusses opportunities and constraints for psychiatry to exert an influence on the quality of life of people suffering from schizophrenia. Using the example of neuroleptic drug treatment, the opportunities to both positively and adversely affect quality of life by means of psychiatric treatment are illustrated. De-institutionalisation was used as an example for demonstrating the effect of the quality of mental health services. The fact that efforts on the part of professional helpers to achieve improvements in their patients' quality of life are constrained by existing economic and socio-cultural conditions is shown by discussing the stigmatization of people with schizophrenia and their situation on the labour market.

[Results of a survey of 549 patients regarding long-term clinical outcome and quality of life four years after PTCA]

BACKGROUND

Quality control becomes increasingly important in interventional cardiology. Since in most health care systems, clinical treatment of patients who underwent percutaneous transluminal coronary angioplasty (PTCA) is left to general practitioners, important information on the clinical long-term outcome is lost for the cardiologic centers. Aim of this study was to evaluate the clinical status of these patients 4 years after treatment with a PTCA at our institution.

PATIENTS AND METHODS

Inclusion criterion was the treatment with a PTCA within July 1, 1989 to June 30, 1991 (549 patients). A questionnaire was sent to all patients (45 +/- 7 months after PTCA). Four time-points were defined: before PTCA (T1), directly after PTCA (T2), 3 months after PTCA (T3) and actual status (T4).

RESULTS

Questionnaires of 500/549 (91.1%) patients could be analyzed. One-hundred and fifteen patients (23%) had to undergo reinterventions: 69 (13.8%) had a re-PTCA and 46 (9.2%) patients an operative revascularization. At T4, 11.2% patients still had disturbing angina. Within the study period 35 patients (7%) died. Two-hundred and nineteen patients attended a rehabilitation institution. At T4, the amount of patients with little angina was not different comparing patients with/without the attendance of a rehabilitation institution (60.7% vs 66.4% p = 0.29). The rate of new pensioners after PTCA (n = 114 [22.8%]) was higher in the group of patients who attended a rehabilitation (68 patients [13.6%] with vs 48 patients [9.2%] without attendance, p = 0.0036). The attendance of a rehabilitation institution, however, had positive effects on changes of the life style and eating habits.

CONCLUSIONS

This retrospective inquiry was found to be a useful tool (response rate 91.1%) for quality control in interventional cardiology. Important information concerning the quality of the interventions (low reintervention rate) and the long-term outcome of our patients (low rate with severe angina at T4) could be acquired.

Quality and costs of community-based residential supports, village communities, and residential campuses in the United Kingdom

The costs, nature, and benefits of residential supports were examined for 86 adults with mental retardation living in village communities, 133 adults living in newly built residential campuses, and 281 adults living in dispersed housing schemes (small community-based group homes and supported living). Results indicated that (a) the adjusted comprehensive costs of provision in dispersed housing schemes were 15% higher than in residential campuses and 20% higher than in village communities; (b) dispersed housing schemes and village communities offered a significantly greater quality of care than did residential campuses; and (c) there appeared to be distinct patterns of quality of life benefits associated with dispersed housing schemes and village communities, with both approaches offering a greater quality of life than did residential campuses.

Depression and anxiety as predictors of outcome after myocardial infarction

OBJECTIVE

The objective of this study was to investigate the significance of emotional distress immediately after a myocardial infarction as a predictor of physical, psychological, and social outcomes and resource use.

METHODS

In an epidemiological survey, demographic and cardiological data were obtained for all patients from a defined geographical area who had had a myocardial infarction (according to diagnostic criteria of the Monitoring Trends and Determinants in Cardiovascular Disease [MONICA] trial). Hospital survivors were interviewed and were asked to complete self-report assessments on mental state and quality of life. Full replies were available at baseline for 347 subjects. Self-report follow-up questionnaire information was collected 3 months and 1 year later.

RESULTS

Fifteen percent of patients scored as probable cases of anxiety or depression. They were more likely than noncases to report preinfarct distress and poor adjustment (as indicated on the 36-item Medical Outcome Study short form). There was an improvement at 3 months, but there was little overall or individual change after that time. Anxiety and depression did not predict subsequent mortality but did significantly predict poor outcome at 1 year on all dimensions of the 36-item short form quality-of-life measure and on specific measures of everyday activity and reports of chest pain, use of primary care resources, and secondary prevention lifestyle changes.

CONCLUSIONS

Subjects who are distressed in the hospital are at high risk of adverse psychological and quality-of-life outcomes during the ensuing year. Our findings strengthen the argument for in-hospital identification and treatment of patients with depression and anxiety after myocardial infarction.

[Mental disorders and the course of opiate dependence]

OBJECTIVE

The present study investigates the hypothesis of a relationship between mental disorders and symptoms on the one hand and the extent of drug consumption and the addiction-related problems of opiate dependents on the other hand.

METHODS

In a five-year follow-up study in Hamburg among 350 opiate dependents who, at the time of the initial survey, were in contact with the drug help system, 219 clients (63%) could be interviewed at (so far) three different times of investigation. Standardised questionnaires like the EuropASI, CIDI, SCL-90-R, STAI and BDI were used for the interviews.

RESULTS

The general life situation of the surveyed persons has on the whole improved in the course of the last two to three years. Also the average drug consumption clearly decreased. Between mental disorders/disturbances and drug dependence or drug-related problems, a linear correlation could be found: An unfavourable course of mental disorders and symptoms correlates with a problematic current life situation of the client. There is also a global relationship between increased drug consumption and the emergence of mental symptoms like depressiveness and anxiety and the psychosocial functional level.

CONCLUSIONS

The expected relationship between mental disturbances and the extent of drug consumption is not very marked. This is in support of the basic assumption that specific constellations of drug consumption and mental disorders do not exist isolated, but that they are related, as elements of a complex pattern, to the development of other areas of life.

Predictors of barriers to treatment and therapeutic change in outpatient therapy for antisocial children and their families

This study examined the role of parent psychopathology and quality of life in predicting barriers to participation in outpatient treatment and therapeutic change among clinically referred children. Children (N = 169) referred for oppositional, aggressive, and antisocial behavior and their families participated. The major findings were that (1) higher levels of parent psychopathology and lower levels of quality of life predicted the subsequent emergence of perceived barriers to treatment in the parents and therapeutic changes among the children, (2) these effects were not explained by socioeconomic disadvantage or severity of child dysfunction, (3) perceived barriers and therapeutic changes were related and this relation was not explained by other family and child predictors, (4) as the level of perceived barriers increased among families, the amount of therapeutic change and the proportion of children who made a marked change decreased, and (5) parent perception of the relevance and demandingness of treatment were salient dimensions contributing to the relation between perceived barriers and therapeutic change. The conceptual and applied implications of relating barriers to treatment and therapeutic change are discussed.

Sports, recreation and employment following spinal cord injury--a pilot study

STUDY DESIGN

A pilot postal survey.

OBJECTIVE

To examine the levels of sporting/recreational activities, education and employment in people with spinal cord injury (SCI) and to assess if involvement in sport and recreation is associated with higher levels of education and employment.

SETTING

National Spinal Injuries Centre (NSIC), Stoke Mandeville Hospital, Aylesbury, UK.

METHODS

Forty-five subjects, who met the following criteria: SCI at level C5 or below, wheelchair dependent, aged between 18 and 50 at the time of injury, injured at least 10 years ago, admitted to the NSIC within 6 months of injury and resident in the UK, completed a 26-item postal questionnaire.

RESULTS

Among the 45 subjects 47% participated in physical activities (20% in sport; 27% in recreation), 33% were employed (29% full-time) and 18.5% had undergone further education at the time of the survey. Participation in sports as well as employment status decreased after injury (P<0.01) usually as a result of poor access to sports and work facilities. Only 4% of investigated SCI patients started to practise physical activity after the accident whilst 42% stopped.

CONCLUSIONS

Levels of sporting/recreational activities and employment decreased significantly after injury. No significant correlation was found between sport/recreation involvement and education/employment status. Further investigation with a large number of participants that will enable additional analysis of subgroups, such as level of injury and functional independence, is required.

Oral health related quality of life--views of the public in the United Kingdom

OBJECTIVE

This study was designed to determine the United Kingdom public's perception of how oral health affects quality of life (QoL) and to determine socio-demographic variations in these perceptions.

RESEARCH DESIGN

The vehicle for this study was the ONS Omnibus Survey in the UK. A random probability sample of 2,668 eligible addresses was selected from the British Postcode Address File. Setting The data were collected by qualitative, face-to-face interviews with respondents, nation-wide, in their homes, about how their oral health status affected their QoL.

PARTICIPANTS

1,778 adults aged 16 years or older across the UK took part in the study.

RESULTS

75% (1,340) believed their oral health either enhanced or reduced their QoL. Most frequently, this was perceived as being the result of its effect on eating. comfort and appearance. Other ways in which QoL was affected are also presented. Sociodemographic variations were apparent. For example, people from higher socio-economic backgrounds believed that their oral health enhanced their QoL to a greater degree (OR=1.46, CI=1.20, 1.78) than the lower socio-economic groups. Women claimed that their oral health had a greater negative effect on QoL than did men (OR=1.36, CI=1.11, 1.64). Younger people (16-64 years old) reported that their oral health status reduced and enhanced QoL more than older adults (65 years and over) (OR=1.59, CI=1.23, 2.04).

CONCLUSIONS

The study shows that the UK public perceives oral health as affecting their QoL in a variety of physical, social and psychological ways and that significant socio-demographic variations exist in these perceptions.

[Measurement of quality of life in patients with dementia of Alzheimer type and their caregivers: Schedule for the Evaluation of Individual Quality of Life (SEIQoL)]

Twelve patients with mild to moderate Alzheimer's Disease (AD) and their caregivers were interviewed with the SEIQoL. The SEIQoL measures quality of life by taking into account the relevant determinants for a particular individual. The subject rates 5 areas in life most important to the quality of life. The relative contribution of each area to the overall quality of life is then calculated with a multiple regression analysis programme developed for the purpose. Next the SEIQoL Index score, validity and reliability are computed. One patient was unable to complete the interview. The remaining (8 women, 3 men, mean age 71.3 years) had a mean SEIQoL Index score of 79.9 (median: 85.4), which is comparable to healthy Dutch elderly. The caregivers (10 spouses, 2 daughters; mean age 67.4 years), on the other hand, had a lower SEIQoL Index score: 62.2 (median: 63.8). Validity and reliability were good for both groups. Thus, caregivers in this pilot study experienced a lower quality of life than AD patients and healthy Dutch elderly. The SEIQoL allows quantitative measurement of completely individualised quality of life for AD patients and their caregivers.

Valuing health-related quality of life. A review of health state valuation techniques

Given the growing need to value health-related quality of life, a review of the literature relating to health state valuation techniques was undertaken to appraise the current theoretical and empirical evidence available to inform on the techniques, to identify consensus, identify disagreement and identify important areas for future research. A systematic search of the literature was conducted, covering standard gamble (SG), time trade-off (TTO), visual analogue scale (VAS), magnitude estimation (ME) and person trade-off (PTO) techniques. The basic concepts of practicality, reliability, theoretical validity and empirical validity formed the criteria for reviewing the performance of valuation techniques. In terms of practicality and reliability, we found little evidence relating to ME and PTO. SG, TTO and VAS have been shown to be practical on a range of populations. There is little difference between the reliability of SG, TTO and VAS, and present evidence does not offer a basis to differentiate between them. When considering the theoretical basis of techniques, we conclude that choice-based methods (i.e. SG, TTO and PTO) are best placed to reflect the strength of preference for health, with the choice between these techniques depending on the study characteristics and the perspective employed. Empirical evidence relating to the theoretical perspective of the techniques has shown that there are problems with all techniques in terms of descriptive validity.

Patients with cancer holding their own records: a randomised controlled trial

BACKGROUND

The burden of cancer care in general practice is increasing. Patient-held records may facilitate effective, coordinated care, but no randomised controlled trials of their use in cancer care have been conducted, and concerns about possible negative effects remain.

AIM

To evaluate the use of a supplementary patient-held record in cancer care.

METHOD

Six hundred and fifty radiotherapy outpatients with any form of cancer were randomised either to hold a supplementary record or to receive normal care. It was explained to record holders that the supplementary record was intended to improve communication with health professionals and act as an aide memoire. After three months, patients' satisfaction with communication and with participation in their own care were assessed. Global health status, emotional functioning, and cognitive functioning were measured using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire.

RESULTS

There were no significant differences between groups in any of the outcome measures. Patients in both groups expressed a high level of satisfaction with communication and participation in their care. Mean (SD) scores in the intervention and control groups were: global health status, 66.8 (24.2) and 65.3 (23.7); emotional functioning, 75.0 (24.6) and 77.4 (22.8); cognitive functioning, 84.5 (21.0) and 84.0 (21.3).

CONCLUSION

A supplementary patient-held record for radiotherapy outpatients appears to have no effect on satisfaction with communication, participation in care, or quality of life.

Sense of coherence and illness appraisal in older women's quality of life

The purpose of this descriptive, correlational study was to test a conceptual model of proposed relationships between physical health limitation, the sense of coherence, illness appraisal, and quality of life in a sample of 137 older women. The typical respondent was 76, widowed, with an income less than $12,000, and several health problems. Hierarchical multiple regression analysis indicated that physical health limitation, particularly symptom bother and functional health, had a significant negative influence on quality of life. However this effect was mediated by sense of coherence and illness appraisal. Regardless of the level of symptoms or functional health, women with higher sense of coherence and more positive illness appraisals had higher levels of quality of life. The findings support the proposed model and further our understandings regarding the protective role of personality resources in perceived quality of life in older women with chronic illnesses.

Perimenopause and the quality of life

The purposes of this study are to describe the frequency and distress of symptoms associated with perimenopause, to examine the changes in the quality of life (QOL) related to perimenopause, and to examine the relationships between symptoms associated with perimenopause and the QOL. A cross-sectional, correlational design was employed. Two hundred fourteen perimenopausal women completed the Women's Health Assessment Scale (WHAS) and the Quality of Life Scale. It was found that vasomotor symptoms were not central to the list of symptoms associated with perimenopause. More women reported psychosomatic complaints as opposed to vasomotor complaints. Compared to the premenopausal period, women during perimenopause experienced slightly, yet significantly decreased, levels of QOL. Multiple regression analysis demonstrated that the psychosomatic symptom category was the sole predictor of the QOL during perimenopause. In summary, psychosomatic symptoms occur most frequently and are most distressful for perimenopausal women in this study. It may be important to manage psychosomatic symptoms to improve the QOL for perimenopausal women.

Posttraumatic stress disorder symptoms, psychological distress, personal resources, and quality of life in four groups of Holocaust child survivors

The objective of the present study was to inquire into the long-term effects of child survivors' Holocaust experience. To this end, 170 Holocaust survivors who were born after 1926 completed questionnaires with regard to psychological distress, Posttraumatic Stress Disorder (PTSD), Quality of Life (QoL), Self-identity, and Potency. The survivors were divided into four groups based on the setting of their experience during the Holocaust: Catholic Institutions, Christian foster families, concentration camps, and hiding in the woods and/or with partisans. Results showed that survivors who had been with foster families scored significantly higher on several of the measures of distress, whereas survivors who had been in the woods and/or with partisans scored significantly higher on several of the positive measures, QoL, potency, and self-identity. The discussion focuses on understanding the different experiences according to developmental theory and sense of control. It was concluded that there are group differences between child survivors according to their Holocaust experience.

Postoperative quality of life in vestibular schwannoma patients measured by the SF36 Health Questionnaire

OBJECTIVE

To quantify the postoperative quality of life in patients following surgical treatment for vestibular schwannoma.

STUDY DESIGN

Patient self-assessment using the short form 36 (SF36) multidimensional quality of life health questionnaire. Sex- and age-matched normalized scores were calculated using a standardized process and accepted normative data.

SETTING

Tertiary referral skull base unit.

RESULTS

An 80% response rate (90 patients) was achieved. The postoperative quality of life in vestibular schwannoma patients, as quantified by seven of the eight SF36 health scales was less than the appropriate matched healthy standard. Comparison of a variety of preoperative patients and tumor factors-different operative approaches (translabyrinthine and retrosigmoid), tumor size (group cut of points of tumor diameter 1.5 mm and 2.5 mm), patient sex, and ranking of patient age-showed no statistically significant difference in measured quality of life outcomes for each of these traditional predictors.

CONCLUSION

Reduced quality of life in patients after surgical treatment for vestibular schwannoma, coupled with the low tumor growth rates and minimal preoperative symptoms, supports a conservative approach to patient management. The advantages and disadvantages of a variety of approaches used to measure the quality of life after surgical treatment of vestibular schwannoma and their impact on clinical decision making for patients, are discussed.

Long-term quality of life of patients with head and neck cancer

OBJECTIVES

To describe prospectively the long-term changes of quality of life and mood in patients with squamous cell carcinoma of the head and neck treated with surgery and/or radiotherapy.

PATIENTS AND METHODS

One hundred seven patients completed the European Organization for Research and Treatment of Cancer (EORTC) Core Questionnaire, the EORTC Head and Neck Cancer Module, and the Center for Epidemiological Studies Depression Scale before treatment, and 6, 12, 24, and 36 months later.

RESULTS

There was limited deterioration of physical and role functioning and of many head and neck symptoms at 6 months, with improvement thereafter. After 36 months only physical functioning, taste/ smell, dry mouth, and sticky saliva were significantly worse, compared with baseline. Female sex, higher cancer stage, and combination treatment were associated with more symptoms and worse functioning. Despite physical deterioration, there was a gradual improvement of depressive symptomatology and global quality of life.

CONCLUSION

Treatment for head and neck cancer results in short-term morbidity, most of which resolves within 1 year. Despite an initially high level of depressive symptomatology, there is gradual improvement of psychological functioning and global quality of life over the course of 3 years. In this prospective study, the impact of the disease and its treatment in long-term survivors seems to be less severe than it is often assumed to be.

Effects of melatonin on the quality of life in patients with delayed sleep phase syndrome

OBJECTIVE

The purpose of this study was to compare health-related quality of life of delayed sleep phase syndrome (DSPS) patients with a random Dutch sample and four samples of patients with other chronic conditions. We also investigated the effectiveness of treatment with 5 mg of melatonin on the quality of life of DSPS patients.

METHODS

Forty-three DSPS patients completed a quality-of-life questionnaire (Medical Outcome Study Short Form-36 [MOS SF-36] health survey) just before and 2-9 months after participation in a clinical trial involving the administration of melatonin. Scores were compared with responses to the same survey by a random Dutch sample and by patients with sleep apnea, clinical depression, migraine, and osteoarthritis.

RESULTS

MOS SF-36 scales scores were significantly lower in DSPS patients relative to age- and gender-adjusted norms for the Dutch sample. Some health dimensions were more affected, and others less affected, by DSPS compared with the other chronic conditions. Melatonin treatment improved all scales except the scale "role due to emotional problems."

CONCLUSION

DSPS has a unique significant quality-of-life burden that seems to be improved by treatment with melatonin.

Psychological functioning and quality of life following bone marrow transplantation: a 3-year follow-up study

OBJECTIVE

To assess changes in quality of life and psychological distress following bone marrow transplantation (BMT) and variables related to this change.

METHODS

One hundred twenty-five consecutive patients who underwent bone marrow transplantation (BMT) at the Leiden University Medical Centre between 1987 and 1992 filled in questionnaires measuring quality of life, functional limitations, psychological distress, anxiety, depression, self-esteem, and health locus of control. Measurements were taken before the BMT; 1 month after discharge; and 6 months, 1 year, and 3 years after the BMT.

RESULTS

Three years after BMT, a quarter of the patients continued to experience serious functional limitations. Thirteen percent of the patients scored >4 on the General Health Questionnaire (GHQ-12), a percentage comparable to general population prevalence. Quality of life was reported to be good to excellent by almost 90% of the patients at three years. Changes in quality of life could be explained entirely by changes in functional limitations and somatic symptoms. Changes in psychological distress were also related to these measures, and furthermore to baseline psychological functioning.

CONCLUSION

Although patients were doing well three years after BMT, there was a group of patients needing help. In interventions special attention should be given to patients with ongoing psychological problems. Emphasis should be on coping with physical limitations.

Depression is strongly associated with alexithymia in the general population

OBJECTIVE

This study examines how alexithymia and depression are related to each other in men and women in a sample of Finnish general population (n = 2018).

METHODS

Alexithymia was screened using the 20-item version of the Toronto Alexithymia Scale. Level of depression was assessed using the 21-item Beck Depression Inventory (BDI). Life satisfaction was estimated with a structured scale.

RESULTS

The prevalence of alexithymia was 12.8% in men and 8.2% in women. However, the prevalence of alexithymia was 32.1% among those having BDI scores of > or = 9, but only 4.3% among the nondepressed subjects (p < 0.001). The BDI scores explained 29.2% of the variation in TAS-20 scores. Alexithymia was associated with several sociodemographic factors if depression was not taken into account. However, after including depression in the logistic regression models, only depression and low life satisfaction were associated with alexithymia, both in men and women.

CONCLUSION

These results suggest that alexithymia has a close relationship to depression in the general population. The impact of social factors on alexithymia may be primarily explained by depression. Depression must be taken into account as a confounding factor when studying alexithymia in general populations due to the strong association between alexithymia and depression.

Experiences of micturition problems, indwelling catheter treatment and sexual life consequences in men with prostate cancer

Men with prostate cancer (n=25) were interviewed, focusing on experiences of micturition problems, indwelling catheter treatment and sexual life consequences. Narrations were found to be practical and technical descriptions rather than emotional, and experiences were described with reduction and negligence regarding personal well-being and the impact of problems. Phenomenological-hermeneutic analysis was used and findings ordered in subthemes and themes of meaning. Micturition problems, catheter treatment and sexual life problems were all phenomena that radically affected the clients' autonomy and life quality and changed the life continuum. Impact from the disease was either accepted or not and related to what had already been borne in life. Experiences were linked together, each of them giving rise to feelings of physical deterioration and fear of ridicule, and hidden from others. Maintaining self-image and social role was important and connected with the degree of perceived deprivation of life content. Responsibility for medical decisions was left to professionals while everyday problems with micturition, catheters and sexual life were regarded as the men's sole responsibility. Findings were interpreted to mean that comparing the personal situation with that of others worse off made the life situation look better. The clinical implication of this study was that because the men came forward with their problems when given time to talk in their own way these areas should be given time and interest in the nursing care. Interpretation did not provide a unified picture of problems. Thus, nurses will have to seek men's individual experience actively and give legitimacy to patients' problems by opening up opportunities to speak about otherwise concealed problems. Then it may be possible to provide solutions that may ease the men's burdens.

Mental quality of life: an indicator of unmet needs in patients with diabetes

This exploratory study investigates the quality of life needs of 173 individuals being treated for type 2 diabetes over a six month period of time. It samples patients whose primary care providers practice the most current model for delivering care, diabetes disease management. These physicians utilized a multidisciplinary diabetes education program to facilitate the patient-provider knowledge-based partnership essential in discase management. Patient quality of life changes were measured by the SF-36. A paired samples t-test showed significant diminishment in patients' mental quality of life indicating diminished overall emotional functioning, negatively impacting quality of life; possibly due to the effects of time. Multiple regression results also indicated that patients at risk for major depression and at risk for major depression superimposed on dysthymia experienced significantly diminished mental quality of life. These findings suggest that enhanced mental health assessment and mental health services provided by social workers in diabetes education programs and/or primary care settings would improve patient mental quality of life.

Impact of advertisement and clinic populations in symptoms and perception of irritable bowel syndrome

BACKGROUND

This study assessed the impact of recruitment on irritable bowel syndrome clinical trials, by determining whether irritable bowel syndrome patients recruited from advertisement or a specialty clinic differ in clinical and physiologic measures.

METHODS

We prospectively surveyed 657 irritable bowel syndrome patients who either: (i) were referred from a functional bowel disease clinic (52%); or (ii) responded to advertisement for clinical trials (48%), using questionnaires about bowel and psychological symptoms, and quality of life. In a subset of 42 irritable bowel syndrome patients (29 advertisement and 15 clinic patients), rectal discomfort thresholds were measured before and after repetitive sigmoid stimulation.

RESULTS

While the advertisement population more commonly consulted primary care physicians, the clinic population more commonly consulted gastroenterologists. The clinic population reported more prevalent and severe abdominal pain, and higher psychological symptom scores, while the advertisement population had greater quality of life. In the visceral perception studies, both subgroups were hypersensitive to rectal distension.

CONCLUSION

Compared to the clinic population, the advertisement population had less severe abdominal pain and psychological symptoms, better quality of life but similar visceral perception. The differences in clinical self-reports may have consequences for enrolment of these different patient populations into clinical trials.

Positive effects of illness reported by myocardial infarction and breast cancer patients

This study investigated the positive effects or changes that patients identified in their lives following a myocardial infarction (MI) or breast cancer. One hundred and forty-three patients were assessed in hospital following a first-time MI and 52 breast cancer patients were assessed on referral for radiotherapy. Approximately 3 months later both groups were asked if any positive changes had taken place in their lives following their illness. Patients' written responses to a single open-ended question were read independently by three judges who identified seven major positive themes. Approximately 60% of each patient group reported positive changes from their illness and the reporting of such changes was unrelated to illness severity. The most common theme reported by MI patients was healthy lifestyle change (68%), whereas, for breast cancer patients, it was improved close relationships with others (33%). These results are discussed in terms of the way patients make sense of and adapt to chronic illness.

An Italian-Australian comparison of quality of life among people with intellectual disability living in the community

This paper reports the measurement of both objective and subjective quality of life in samples of people either with intellectual disability or from the general adult population, drawn from Australia and Italy. Measures were made using the Comprehensive Quality of Life Scale. Generally, it was found that the scores for all groups were comparable. This finding is consistent with the provision of generally decent objective living conditions in both countries and subjective well-being homeostasis, wherein subjective quality of life is held within a predictable range. These results are discussed in the context of measurement difficulties imposed by the need for simple Likert scales and subjective data which are strongly negatively skewed.

Subjectively healthy elderly consuming a liquid nutrition supplement maintained body mass index and improved some nutritional parameters and perceived well-being

OBJECTIVE

To evaluate regular use of a liquid nutrition supplement by subjectively healthy elderly persons in terms of body mass index, nutrient intake, selected biochemical parameters, and perceived quality-of-life changes, and to identify advantages and limitations of use.

DESIGN

A 16-week intervention study in which subjects were assigned randomly to either a supplemented group or a control group and compared in terms of intergroup and intragroup differences in weight, food intake, blood values, and quality-of-life indexes. Adherence to protocol was monitored by monthly visits with an interviewer and food intake records.

SUBJECTS/SETTING

Seventy-one independent living, older Canadian adults (mean age = 70 +/- 7 years) consuming on average less than 4 servings of fruit and vegetables daily and a supplement-free diet before the study. Subjects were without functional limitations and did not require therapeutic diets or medical treatments that affect nutritional status. Data were collected in home interviews. Blood for analysis was obtained from a subsample of 36 subjects.

INTERVENTION

Inclusion of six 235-mL cans of liquid nutrition supplement weekly into the self-selected dietary patterns of the supplemented group.

STATISTICAL ANALYSIS

Results were analyzed by Student t tests or Wilcoxon rank sum test, analysis of variance, and multiple stepwise regression.

RESULTS

Body mass index, energy intake, and consumption of fruit and vegetables did not change throughout the study. In the supplemented group, statistically significant increases occurred from baseline to termination of the study in these nutrients: protein, calcium, iron, magnesium, and folate. Serum albumin, folate, ferritin, hemoglobin, and zinc values were within the normal range for the supplemented and control groups. Scores for the Medical Outcomes Study 36-Item Short-Form Health Status scales increased for the supplemented group from baseline to termination for vitality and general health perception. Values for the General Well-Being Questionnaire improved for anxiety and general well-being. Of the dietary predictors, folate intake explained the most variance for vitality and for general well-being, 8.6% and 14.2%, respectively.

APPLICATIONS

A liquid nutrition supplement could be recommended to the elderly when energy maintenance and increases in nutrient intake are necessary and convenience is an important consideration. Dietetics professionals should address the issues of affordability of the supplement, the role of food in achieving nutritional adequacy, and overall quality of life of clients. Folate intake as a predictor of perceived general well-being and vitality requires further investigation.

Complete resolution of heartburn symptoms and health-related quality of life in patients with gastro-oesophageal reflux disease

BACKGROUND

Medical treatments for gastro-oesophageal reflux disease (GERD) vary in their ability to completely resolve heartburn and other symptoms. Although GERD reduces health-related quality of life (HRQL) little is known about the relationship between resolution of heartburn symptoms with medical therapy and HRQL. We evaluated the association between complete resolution of heartburn symptoms and functioning and well-being in three samples of patients with GERD.

METHODS

We analysed baseline and follow-up assessments of heartburn symptoms and HRQL scores from three clinical trials (total n=1351) comparing omeprazole and ranitidine for acute symptomatic treatment of GERD. Heartburn symptoms were measured using patient diaries and/or patient self-report. HRQL was assessed using the Psychological General Well-Being Index (PGWB) in all three clinical trials and the SF-36 Health Survey in two clinical trials. Resolution of heartburn symptoms was defined as no heartburn reported during the assessment period.

RESULTS

We observed statistically significant differences favouring patients with no heartburn symptoms on the PGWB total score (P=0.018 to P < 0.0001) and anxiety (P=0.002 to P < 0.0001), general health (P=0.05 to P < 0. 0001), positive well-being (P=0.028 to P < 0.0001) and vitality (P=0. 05 to P < 0.0001) sub-scale scores at 4-14 weeks. Patients with no heartburn reported better SF-36 pain (P=0.005 to P < 0.0001) and general health perceptions (P=0.032 to P < 0.0001) compared with patients still experiencing heartburn symptoms at 4-24 weeks. SF-36 physical component summary scores were significantly better in patients with no heartburn symptoms compared with patients with heartburn symptoms at 4-24 weeks (P=0.013 to P=0.009), while mental component summary scores were only significantly different at 24 weeks (P=0.0005) in one of the two studies where the SF-36 was utilized.

CONCLUSIONS

Complete resolution of heartburn symptoms was consistently associated with improvement in HRQL; the greatest impact was observed on measures of psychological well-being and physical functioning and well-being. Effective treatment of GERD that completely resolves heartburn results in clinically significant improvement in patient HRQL.

Measuring quality of life in paediatric patients

The purpose of this paper is to highlight important considerations in the measurement of health-related quality of life (HR-QOL) in paediatric populations. Considerations specific to the evaluation of HR-QOL in children include children's understanding of the questions being asked, their understanding of their own disease, using parents as proxies, time perception problems and simply the fact that children are continually changing. We provide a review of the currently available literature regarding paediatric HR-QOL assessments to examine the different instruments and approaches taken to assess HR-QOL in paediatrics. Asthma-specific measures are discussed as examples of condition-specific HR-QOL instruments because of the considerable amount of methodological and developmental work that has been conducted in this disease. Our search strategy revealed 15 main generic and 5 main asthma-specific instruments that met our criteria for inclusion. The main points high-lighted for each instrument are the description of domains, respondent (i.e. the child, parent or clinician), age group, number of items, format of instrument (usually self-administered or by interview), original country and language, and the existence of translations. For the various studies in which the different instruments are used, the issues of patient population tested, sample size, reliability and validity are addressed. Although this paper does not attempt to be an exhaustive study of paediatric HR-QOL instruments, we provide an overview of the main generic and asthma-specific instruments, as well as an examination of the different methods used in assessing paediatric HR-QOL. Many challenges exist in the measurement of HR-QOL in paediatric patients. With increased attention to the considerations high-lighted, the field will continue to grow, and the usefulness and application of HR-QOL measures in paediatric patients is likely to improve.

Quality of life in depression: daily life determinants and variability

Identifying daily influences on subjective well-being can be helpful in understanding the burden of depression. This study used experience sampling methodology (ESM) to examine the contribution of mood states, physical complaints and enjoyment of activities to a momentary measure of quality of life (mQoL), assessed by responses to the question 'In general, how is it going with you right now?' Sixty-three depressed and 22 healthy control subjects completed ESM self-reports during daily activities, 10 times per day for 6 days. In comparison to control subjects, depressed subjects had lower levels of mQoL, positive mood, and enjoyment of activity, higher negative mood, and more frequent and severe complaints. Depressed subjects were more likely than control subjects to be doing nothing and less likely to be engaged in work. Multilevel regression analysis showed that positive mood and enjoyment of the current activity were associated with higher mQoL, whereas negative mood and complaints were associated with lower mQoL. In depressed subjects, mQoL was more variable over time than in control subjects. In contrast to the ESM results, only negative mood and depression were significant predictors of global measures of QoL. We conclude that QoL has important situational determinants that can in part explain the impact of depression on daily functioning and well-being.

Item response models for longitudinal quality of life data in clinical trials

Assessment of quality of life is becoming standard in clinical trials. A popular method for measuring quality of life is with instruments which utilize multiple-item subscales, in which each item is scored on a Likert scale. Most statistical methods for the analysis of quality of life data in clinical trials do not explicity consider the properties and psychometric features which were of interest in scale development. In this regard, the measurement and statistical summarization of quality of life data, along with the clinical interpretation, can be somewhat disjoint from the psychometric concerns of the development process. The aim of this paper is to address the complicated issues present in analysing multiple-item ordinal quality of life data in clinical trials while maintaining fidelity to the psychometrical foundations upon which quality of life instruments are built. Accomplishing this will require the development of item response models which recognize the longitudinal aspects of clinical trial designs as well as the potential problem of informatively missing data. A general item response modeling approach is presented for longitudinal multiple-item quality of life data measured on ordinal scales with model components for missing data mechanisms and latent trait regression on treatment indicators and other covariates.

Impact of osteoarthritis and analgesic treatment on quality of life of an elderly population

To determine the quality of life of elderly patients with osteoarthritis (OA) compared with that of their peers with no chronic illnesses and to investigate the associations between analgesic use and quality of life.

SUBJECTS

Patients >65 years of age with OA taking analgesics with (n = 33) and without (n = 26) comorbidities, and control patients with no chronic illness and not taking analgesics (n = 37).

METHODS

Quality of life was assessed by the SF-36 and level of pain was measured by a visual analog scale. Multiple regression analysis was used to determine the medication characteristics and additional patient factors significantly associated with SF-36 scores.

RESULTS

OA patients had significantly (p < 0.05) lower scores than control patients in all quality-of-life domains. OA patient scores were lowest for the domains of role-physical, bodily pain, and physical functioning. OA patients with comorbidities also had poorer general and mental health. Pain- and analgesic-related factors were significantly (p < 0.05) associated with physical health status, reduced vitality, general health, and social functioning. A better quality of life was associated with noncompliance, fewer visits to the physician, and taking oral nonsteroidal antiinflammatory agents. Presence of adverse drug reactions and sleep disturbance did not influence SF-36 scores significantly.

CONCLUSIONS

Quality of life of elderly OA patients with and without additional comorbidities was significantly poorer than that of their healthy peers, particularly in the domains associated with physical status, but also affecting vitality, social functioning, and general health. Level of pain suffered and perceived effectiveness of analgesic medication in pain control were important factors associated with quality of life.

Observational study in adult hypopituitary patients with untreated growth hormone deficiency (ODA study). Socio-economic impact and health status. Collaborative ODA (Observational GH Deficiency in Adults) Group

OBJECTIVE

The aim of the present study was to assess the socio-economic impact at baseline and after one year of follow-up of clinical and health status characteristics and laboratory tests of adult-onset GH deficiency (AGHD), a well-known clinical entity, in a large group of Spanish hypopituitary patients with untreated AGHD.

DESIGN AND METHODS

A total of 926 eligible patients with GHD (GH </= 5 ng/ml after stimulation) and at least one further pituitary hormone deficiency were retrospectively studied; 356 of these were followed for one year. Complete physical examination, IGF-I, lipid and routine biochemistry measurements and health-related quality of life (HRQoL) with the specific QoL-Assessment of Growth Hormone Deficiency in Adults (AGHDA) questionnaire were assessed at baseline and at 12 months in the prospective study. Health status and health-economic evaluation were measured by a specific questionnaire and a patient diary and compared with Spanish population study results.

RESULTS

Clinical characteristics and laboratory tests of AGHD showed a higher incidence of cardiovascular risk factors and mortality compared with the general population (hypercholesterolaemia in 29% vs 18% and hypertension in 22.1% vs 14. 9%). QoL-AGHDA scores for patients were significantly worse (P<0.01) and direct health costs were higher than in the general population.

CONCLUSIONS

Hypopituitary GHD adults had more cardiovascular risk factors, higher mortality, worse HRQoL and higher absolute health costs than the general population in Spain.

The impact of spinal cord injury on men's time use

BACKGROUND

Despite evidence of the relationship between time use and health and well-being, and the World Health Organization's recognition of activity limitation as a measure of dis-ability, there has been limited investigation into the activity patterns of persons with disabilities.

METHODS

Interviews and time diaries to provide preliminary descriptive and analytical information about the daily time use patterns of men with a spinal cord injury (SCI) living in the community (n=312) compared with the time use data of able-bodied men (n=3617) collected as part of the 1992 Canadian General Social Survey. The study also examined relationships between time use by men with SCI and selected factors (severity of disability and socioeconomic status).

FINDINGS

Statistically different time use patterns between the SCI and able-bodied subjects. The men with spinal cord injury spent on average 7.2 h in leisure activities (able-bodied men=6.0 h); 4.7 (7.7) h in productivity; 3.7 (2.3) h in personal care; and 8.5 (8.0) h sleeping. The SCI men's lesser productivity time was accounted for largely by the lack of time spent in paid work. The average time use of the SCI sample showed the most time spent in passive leisure pursuits such as watching TV and listening to the radio. The sample rated their satisfaction with their time use as mediocre, but levels of adjustment to disability were moderate to high. Regression analysis revealed that severity of disability (lesion level, functional independence, environment) did not predict the amount of time spent in personal care, productivity, leisure, or sleep. Socioeconomic status had a mild predictive relationship with time allocation.

IMPLICATIONS

The findings suggest men with SCI are socially isolated relative to their able-bodied peers. Recommendations are made and include both methodological considerations for further time use studies with persons with SCI, and policy recommendations. The latter focus on the need for rehabilitation, education and resources that go beyond functional independence such that persons with SCI can expand both their leisure and productivity roles and become better socially and economically integrated into society.

Patients' perception of recovery after third molar surgery

PURPOSE

This study evaluated patients' perceptions of recovery after third molar surgery.

METHODS

Two hundred forty-nine patients (age 13 to 37 years) at 2 clinical centers were enrolled in a prospective study before the surgical removal of third molars. Each patient was given a 21-item Health-Related Quality of Life instrument (HRQOL) to be completed each postoperative day (POD) for 14 days. The instrument was designed to assess patients' perception of recovery: pain, oral function, general activity measures, and other symptoms. Pain dimensions were recorded with a 7-point Likert-type scale; all other conditions were measured on 5-point Likert-type scales. The impact of each predictor variable such as age, gender, and length of surgery on recovery was assessed with Cochran-Mantel-Haenszel statistics, controlling for clinical center.

RESULTS

After the 14-day postoperative period, 201 of the original 249 patients returned the completed HRQOL instrument; the 48 patients who did not return their diary had third molar conditions and surgery similar to the 201 patients who responded. On POD 1, 63.5% of patients reported their worst pain as severe (score, 5 to 7/7) at some time during the day. By POD 7, only 15% of patients reported their worst pain as severe. Average pain levels were much less; 29% reported their average pain as severe (score, 5 to 7/7) on POD 1, decreasing to 5.5% by POD 7. Patients experienced substantial interference in oral function; chewing, 85%; mouth opening 78.5%, and speaking 37.5% on POD 1. By POD 6, oral function had improved; chewing, 19%, mouth opening, 15%; and speaking, 1.5%. General measures also were affected on POD 1; social activity, 61.5%; recreation, 70.5%; and daily routine, 60%. Patients assumed a more normal lifestyle by POD 5. Swelling seemed to be at its maximum on PODs 1 and 2 (day 1, 53%; day 2, 61%) and decreased markedly by POD 5 (10%). Food collection in the surgical sites posed the biggest problem for patients on POD 9 (20%). Age was not a predictor of prolonged recovery. However, surgery time 30 minutes or longer, or having all third molars below the occlusal plane, did prolong recovery. Females also reported a longer recovery period.

CONCLUSIONS

This information is valuable to patients deciding on third molar surgery and to clinicians providing informed consent.

Quality of life assessment in MND: development of a social withdrawal scale

A scale to measure 'social withdrawal,' was developed specifically for use with MND patients. Scale design was based upon patient-focused interviews which were used to explore patients' concerns. The impact the condition had upon their social interactions with others was salient for all patients and affected their overall quality of life. Using issues raised by patients, a 23-item scale was generated to specifically and quantitatively measure social withdrawal and this scale was psychometrically evaluated. The scale was administered to a sample of 23 patients at varied stages of progression of MND, and to a control group of patients with arthritis with similar levels of physical disability. For MND patients withdrawal from the community was found to be closely related to severity of physical symptoms and depression. Specific patients were identified who are particularly susceptible to withdrawal and depression. Comparison of the pattern of withdrawal in the MND and arthritis patient groups suggested that there may be differences between the factors governing social withdrawal in different patient populations.

[Quality of life in children with sickle cell disease in Amsterdam area]

OBJECTIVE

To determine the differences in quality of life between children with sickle cell disease and healthy immigrant children.

DESIGN

Descriptive, comparative.

METHOD

The quality of life of children with sickle cell disease between 5 and 15 years old being treated in the Emma Children's Hospital AMC in Amsterdam, the Netherlands, was assessed by using a questionnaire for parents (TNO-AZL Children's Quality of Life Questionnaire (TACQOL) parent form) if the child was between 5 and 11 years old and a questionnaire for children (TACQOL child form) if the child was between 8 and 15 years old. The study period was April-October 1998. The questionnaires were completed by 45 (parents of) patients. The results were compared with a healthy reference group of immigrant children. Statistical analysis was performed using the Student t-Test.

RESULTS

Children with sickle cell disease as well as their parents scored significantly lower on the items general physical, motor and independent daily functioning and on occurrence of negative emotions. No significance was observed for the items cognitive functioning and school performance nor for social functioning or occurrence of positive emotions.

CONCLUSION

In children, sickle cell disease leads to compromised physical and possibly also psychological wellbeing, as well as the experience of decreased independence in daily functioning, but not to compromised cognitive or social aspects of the quality of life.

Health-related quality of life measurements in the assessment of pain clinic results

Following the World Health Organization (WHO) classification of impairment, disability and subjective quality of life, chronic pain disorder has been examined. In this overview impairment has been restricted to non-malignant pain. Disability has been subdivided into disorder-oriented and ailment-oriented symptoms. The disorder-oriented symptoms are pain and depression, the latter emphasizing that pain is an unpleasant sensation. Both pain and depression are essentially subjectively reported symptoms which are unidimensionel, implying that they often are measured by use of visual analog scales. However, the Major Depression Inventory (MDI) and the Symptom Checklist 90 (SCL-90) are appropriate questionnaires itemizing the respective dimensions. The ailment-oriented symptoms have negative social well-being as their core-symptoms, including reduced role-functioning. The Short-Form (SF-36) is an appropriate scale in this respect. Subjective quality of life is essentially measuring positive well-being and the most appropriate measurement instrument is the Psychological Well-Being Schedule (PGWB) or its subscales, among which is the WHO (Five) well-being index.

Methodological issues in the assessment of health-related quality of life in palliative care trials

Palliative care aims at improving the patient's quality of life. Clinical trials, therefore, often include the patient's subjective evaluation of symptoms and psychosocial problems, so-called health-related quality of life (HRQL), as end-points. Unfortunately, there are frequently methodological weaknesses in the assessment of HRQL. This paper discusses four criteria which can be used in the evaluation of the quality of such studies: I. The authors should document that they have included the relevant HRQL issues in the questionnaire. If a trial misses important issues, its results may be misleading. II. The sample size should be sufficient to detect meaningful differences. Many trials are too small. III. The assessment of HRQL should have the appropriate timing, reflecting the research questions. The symptoms and the benefit resulting from treatments are not constant over time and often have cyclic patterns. The results may therefore be dependent on the timing of the administration of questionnaires to patients and on the time frames specified in the instructions. IV. The data must be reasonably complete. Incomplete data cannot be avoided in palliative care research, but missing data due to administrative failures or unrealistic schedules must be avoided. A pilot study may show whether a study is feasible. Missing data are likely to bias results. Many published palliative care studies are suboptimal with regard to one or more of these four criteria. This should be considered when reading published studies and when new trials are planned.

Fatigue. Measures and relation to pain

Fatigue describes reduced capacity to sustain force or power output, reduced capacity to perform multiple tasks over time and simply a subjective experience of feeling exhausted, tired, weak or having lack of energy. Pain and fatigue have several components in common, such as being subjective, prevalent in most patients with cancer and caused by multiple factors of both a physical and psychological nature. In order to explore the relationship between fatigue and pain, data from five studies were used: two random samples from the Norwegian population (n=2323 and n=1965), Hodgkin's disease survivors (n=459), palliative care patients (n=434) and patients with bone metastases (n=94). All patients had completed one or more of the following instruments: EORTC QLQ-C30, SF-36 and/or Fatigue Questionnaire. The level of fatigue was much higher in the two palliative care populations (54.4 and 63.2) as compared to the normal population samples (25.0). Patients with bone metastases had significantly more pain (72.0) than the patients in the palliative care trial (47.4) and norms (20.5). In the two palliative care and bone metastases populations fatigue was almost unchanged over time, while pain was reduced. In the palliative care population a high level of fatigue (80.3) and pain (57.8) was reported 0-1 month before death. The relationship between pain, fatigue and the health-related quality of life domains should be explored in more detail, especially in follow-up studies in order to assess possible changes over time. In addition, the validity of the existing instruments measuring fatigue should be investigated for use in patients with advanced disease and short life expectancy.

Quality of life of cardiac arrhythmia patients after radiofrequency catheter ablation

Radiofrequency catheter ablation (RFCA) has been used to treat cardiac arrhythmias in Thailand since 1992. The effect of this procedure on quality of life has not been systematically studied. The purpose of this study was to assess the impact of RFCA on quality of life in patients with cardiac arrhythmias. Data were collected by interviewing 30 patients from February 1998 to August 1998, before and two months after RFCA. The questionnaire used for this study was created by researchers using Zhan's conceptual framework and SF36 in 4 dimensions--life satisfaction, self-concept and psycho-social well being, health functioning and physical well being, socio-economic and social well being. The questionnaire was validated by experts. Its reliability was tested by using Cronbach's test that gave an alpha coefficient of 0.81. Our study showed that the overall quality of life scores 2 months after RFCA (mean = 179.467, SD = 17.005) were higher than before RFCA (mean = 131.567, SD = 18.680). The results also showed a statistically significant difference (p = 0.000).

CONCLUSION

It was found that RFCA significantly improved the quality of life of patients with various cardiac arrhythmias. However, this study consisted of a small sample size. Further work in this area with a large sample size is needed to confirm this finding.
