End-of-life decisions in Australian medical practice.

OBJECTIVE: To estimate the proportion of medical end-of-life decisions in Australia, describe the characteristics of such decisions and compare these data with medical end-of-life decisions in the Netherlands, where euthanasia is openly practised. DESIGN: Postal survey, conducted between May and July 1996, using a self-administered questionnaire based on the questionnaire used to determine medical end-of-life decisions in the Netherlands in 1995. PARTICIPANTS: A random sample of active medical practitioners from all Australian States and Territories selected from medical disciplines in which there were opportunities to be the attending doctor at non-acute patient deaths, and hence to make medical end-of-life decisions. MAIN OUTCOME MEASURE: Proportion of Australian deaths that involved a medical end-of-life decision, using ratio-to-size estimation based on the sampled doctors' responses to the questionnaire. The response rate was 64%. RESULTS: The proportion of all Australian deaths that involved a medical end-of-life decision were: euthanasia, 1.8% (including physician-assisted suicide, 0.1%); ending of patient's life without patient's concurrent explicit request, 3.5%; withholding or withdrawing of potentially life-prolonging treatment, 28.6%; alleviation of pain with opioids in doses large enough that there was a probable life-shortening effect, 30.9%. In 30% of all Australian deaths, a medical end-of-life decision was made with the explicit intention of ending the patient's life, of which 4% were in response to a direct request from the patient. Overall, Australia had a higher rate of intentional ending of life without the patient's request than the Netherlands. CONCLUSIONS: Australian law has not prevented doctors from practising euthanasia or making medical end-of-life decisions explicitly intended to hasten the patient's death without the patient's request.

Using renal transplantation to evaluate a simple approach for predicting the impact of end-stage renal disease therapies on patient survival: observed/expected life span.

The effectiveness of therapy for a chronic disease can be assessed by evaluating the length of time that a patient survives after receiving treatment. We used a novel means for measuring the effectiveness of renal replacement therapy for patients with end-stage renal disease (ESRD): the ratio of observed life span divided by expected life span. This ratio incorporated observed life span for patients from the time of ESRD and expected life span based on state-specific life-table analyses. A total of 3,782 individuals with ESRD were analyzed (average follow-up, 14.2 +/- 4.9 years); 3, 192 patients in that group received a kidney transplant at some point during their course of ESRD. For each patient, we determined a curve of observed/expected life span. Separate patient groups were analyzed to determine the median population observed/expected life span or the percentage of patients who reached 0.5 observed/expected life span. Younger transplant recipients (<21 years) had a median observed/expected life span of 67%, significantly greater than the median observed/expected life span for those aged 21 to 40 years (49%; P = 0.01) and 41 to 60 years (47%; P = 0.01). Surprisingly, 57% of the patients aged older than 60 years reached their median observed/expected life span (P = 0.02 versus <21 years; P = not significant against all others). A Cox proportional hazards model identified era of immunosuppression (hazards ratio, 0.32) and atherosclerotic vascular disease-related ESRD (hazards ratio, 2.07) as significant variables influencing patient survival and observed/expected life span. This simple ratio is easy to use and may be a helpful tool for assessing the survival benefits of risk-factor modifications and therapeutic advances in transplantation and ESRD care.

Disability-free life expectancy of elderly people in a population undergoing demographic and epidemiologic transition.

BACKGROUND: the major purpose of health and social policy in old age is to increase quality of life of elderly people. In many demographically developing countries, life expectancy is increasing very rapidly, but little information is available on survival free of disability. OBJECTIVES: to determine prevalence and severity of disability among the elderly population and to compare disability-free life expectancy and self-care life expectancy among different age groups and between men and women. DESIGN: a cross-sectional multi-stage random sample survey and routine life tables for Thailand. SETTING: national population of Thailand. SUBJECTS: 4,048 elderly subjects aged 60+ years. RESULTS: prevalence rates (95% CI) of long-term disability and dependency in self-care activities of daily living were 19% (95% CI 17.8, 20.2) and 6.9% (6.1, 7.7) respectively. Rates of disabilities increased with age and women were more disabled than men. The life expectancy and disability-free life expectancy at age 60 for men were 20.3 years and 16.4 years, and for women were 23.9 years and 18.2 years respectively. Self-care life expectancies at age 60, calculated from the prevalence of needing help with basic self-care activities, were 18.6 years and 21.3 years for men and women respectively. Women spent proportionately more of their longer life expectancy in a disabled state than men. Men and women can, respectively, expect that 19% and 24% of their life expectancy at age 60 will be spent in a disabled state, but may expect only about 10% of their life expectancy to be spent unable to manage basic self-care activities of daily living. CONCLUSION: long-term disability is common in old age, affecting a quarter of people over 60 years. However, self-care problems are much less common and suggest that the social and health care consequences of demographic transitions are over-estimated by use of simple questions about limiting long-standing disability. Self-care life expectancy provides a useful monitoring tool for censuses and national disability surveys.

An internalist view on the value of life and some tricky cases relevant to it.

If we understand death as the irreversible loss of the good life, we can give meaning to the idea that for suffering patients in the end stage of their illness, life may become an evil and death no longer a threat. Life may lose its good already in the living person. But what does the good of life consist in, then? I defend an internalist view according to which the goodness of life is intrinsically related to the attitudes, concerns, interests and experiences of the person who is leading the life. This results in the contention that the core of what we understand as the value of the person's life is to be identified with what makes life go well for the person living the particular life. This internalist view does not presuppose (or imply) hedonism or mentalism, nor does it pose an experience requirement. Something may be good for you, because it is valuable as seen from your authentic viewpoint, even if you do not actually experience this goodness, or think otherwise because you are mistaken about your own well-being. To test this position, and the authenticity-requirement it includes, I discuss three cases of patients who are persistent in denying that in their life any value is left and who contend that death is not worse than further living. Internalism acknowledges that in the life of these patients there may be 'functionings' and 'beings' that are worthwhile, where the test of value is at least partially independent of subjective assessment. Still, internalism claims that something truly valuable can only contribute to the good of one's life of it has positive meaning as seen from the attitudinal viewpoint that identifies oneself.

A method for constructing complete annual U.S. life tables.

OBJECTIVES: This report describes a method for constructing complete annual U.S. life tables and for extending the age coverage of the life table to age 100. Previously, annual life tables were based on an abridged methodology and were closed with the age category 85 years and over. In the United States, approximately one-third of the population survives beyond age 85 years. This fact, coupled with improvements in age reporting and the availability of higher quality old-age mortality data, recommends that the life table be closed at an older age. METHODS: The method, similar to that used to construct the decennial life tables, uses vital statistics and census data to calculate death rates for ages under 85 years and Medicare data for ages 85 years and over. Previously, the annual life tables were abridged, and used only vital statistics and census data. CONCLUSIONS: The complete life table methodology described in this report produces estimates of life expectancy at ages 100 years and younger that are consistent with previously published life tables. Complete life tables based on 1996 mortality data compared favorably with published 1996 abridged life tables and with the 1989-91 decennial life tables. The methodology was implemented beginning with final mortality data for 1997.

Effect of postthrombotic syndrome on health-related quality of life after deep venous thrombosis.

BACKGROUND: Postthrombotic syndrome (PTS) is a frequent chronic complication of deep venous thrombosis, yet its impact on health-related quality of life has not been well characterized. We compared generic and venous disease-specific quality of life in patients with and without PTS, and assessed whether quality of life correlated with severity of PTS. METHODS: Subjects with previous deep venous thrombosis were participants in a study of the effects of exercise after deep venous thrombosis. We ascertained PTS and its severity using a validated clinical scale. Subjects completed generic (the 36-Item Short-Form Health Survey) and disease-specific (Venous Insufficiency Epidemiologic and Economic Study quality-of-life questionnaire [VEINES-QOL] and its validated subscale of 10 items on venous symptoms [VEINES-Sym]) quality-of-life measures. Age- and sex-adjusted mean quality-of-life scores were compared in patients with and without PTS, and by severity of PTS. RESULTS: Of the 41 subjects (mean age, 51.2 years), 19 (46%) had PTS. Subjects with PTS had significantly worse disease-specific quality-of-life scores than those without PTS (mean +/- SD VEINES-QOL score, 44.5 +/- 11.6 vs 54.8 +/- 5.4, respectively [P<.001]; mean +/- SD VEINES-Sym score, 45.6 +/- 11.4 vs 54.1 +/- 6.7, respectively [P =.003]), which worsened significantly with increasing severity of PTS. We found no differences in generic quality-of-life scores between subject groups. CONCLUSIONS: Postthrombotic syndrome has a significant impact on disease-specific quality of life that may not be captured by generic quality-of-life measures. Patient-based quality-of-life measures correlated well with physician-assessed PTS. Further research is indicated to assess the value of including quality of life as a routine measure of outcome in clinical studies of patients with deep venous thrombosis and PTS.

Satisfaction of life and late psycho-social outcome after severe brain injury: a nine-year follow-up study in Aquitaine.

In view of assessing their late outcome and satisfaction of life, 79 out of 158 severe traumatic brain injury (STBI) patients who received inpatient rehabilitation in Aquitaine in 1993 were followed by phone interview. Results showed that 9 years on average after their injury, 65 to 85% of these patients were independent for daily living, whereas 35 to 55% only were independent in social life. Most of the patients were satisfied with their autonomy (67%), family life (66%) and financial status (41%), but they were dissatisfied with leisures (36%), vocational adjustment (28%) and sexual life (32%). Satisfaction of life was mostly related to age, gender, physical autonomy, need of help because of cognitive impairment and functional outcome as assessed by the Glasgow Outcome Scale. Severe traumatic brain injury (STBI) stands in industrialised countries as a major Public Health problem and a dreadful human drama for the patients, their families and the community [2]. A great number of STBI patients survive with severe disability, most of them being young adults. The most severely impaired may live only with their parents or in high-cost nursing homes. From a psychological point of view, STBI causes a total and sudden breakdown of the mental states, personality and conditions of life. Life plans and projects are definitively disrupted, satisfaction of life is deeply changed. Rehabilitation aims at improving functional outcome of persons with STBI, and at improving their overall quality of life. Planning for rehabilitation and re-entry into community of STBI patients need to be provided with precise data on their late outcome and disability level. Despite that the concepts of quality and satisfaction of life are difficult to define and moreover to assess, these are also major factors to take into account. The aims of the present study were to assess the late psycho-social outcome of patients hospitalized in Aquitaine for rehabilitation of a STBI 7 to 10 years after their injury, and to ask for their satisfaction of life and subjective feeling of quality of life.

Living with cystic fibrosis: impact on global quality of life.

BACKGROUND: Because of better health care, most people with cystic fibrosis (CF) now survive into adulthood, raising issues related to quality of life. Few studies have focused on satisfaction with broader life domains in people with CF. The aim of this article was to examine the impact of living with CF from a global quality of life perspective. METHODS: The sample consisted of 86 adults with CF recruited from the Norwegian Competence Centre for Cystic Fibrosis and a control group of 1021 individuals from the general population (GP). The Norwegian version of the Quality of Life Scale was used to measure global quality of life (satisfaction with broader life domains) in both groups. RESULTS: The mean global quality of life score was 84.88 for the CF group and 83.33 for the GP group. This difference was significant after controlling for age, sex, educational level, and marital status, indicating that people with CF have better global quality of life. The groups also differed significantly on other specific measures of life satisfaction. Persons with forced expiratory volume in 1 second values below 30% of predicted values reported the lowest mean global quality of life value. CONCLUSIONS: These results suggest the existence of a type of response shift in the CF group through changes in life standards and goals. However, people with CF who have low forced expiratory volume in 1 second values may need special attention from health care professionals on issues related to global quality of life.

Quality of life in geriatric generalized anxiety disorder: a preliminary investigation.

OBJECTIVE: To examine the impact of late-life generalized anxiety disorder (GAD) on health-related quality of life. METHOD: We compared quality of life in 75 treatment-seeking older adults with GAD, 39 of whom had psychiatric comorbidity, with 32 older adults without psychiatric illness. We examined predictors of quality of life in these samples. We also compared data from the GAD patients to published norms from a large national sample of older adults with chronic medical conditions or major depression. RESULTS: Older GAD patients reported worse health-related quality of life across most domains than asymptomatic older individuals. There were no differences in quality of life between GAD patients with and without psychiatric comorbidity, and comorbidity did not predict quality of life in multivariate regression analyses. Presence of GAD or symptoms of anxiety or depression were significantly related to impairment in every domain of quality of life. Comparisons with national norms suggest that older GAD patients report overall worse quality of life than individuals with recent acute myocardial infarction or type II diabetes, and are comparable in quality of life to individuals with major depression. CONCLUSION: Results suggest that late-life GAD is associated with substantial impairment in quality of life, and these findings cannot be explained by psychiatric comorbidity.

Assessment of disease impact in patients with intermittent claudication: discrepancy between health status and quality of life.

OBJECTIVE: To describe similarities and differences between health status and quality of life in patients with intermittent claudication. METHODS: This was an observational study in the vascular outpatient department of a teaching hospital; it concerned 200 consecutive patients with intermittent claudication. Health status was assessed with the RAND-36, and quality of life was assessed with a reduced version of the World Health Organization Quality of Life assessment instrument-100. Scores were compared with those of sex- and age-matched healthy controls. Mann-Whitney U tests were used to detect statistically significant differences ( P < .01) between patients and healthy controls. Pearson correlations were calculated between health status and quality-of-life scores. Differences between correlations were examined by using Fisher z statistics. The upper and lower 10% of quality-of-life scores were compared with the response quartiles of the health status scores. RESULTS: Health status was significantly impaired in all domains. Quality of life was significantly worse with respect to aspects of physical health and level of independence and one global evaluative facets overall quality of life and general health. Quality-of-life assessment with the World Health Organization Quality of Life instrument disclosed patient-reported problems that had not been identified in health status. Conversely, patients did not regard all objective functional impairments as a problem. Pearson correlations ranged from 0.20 to 0.74. There were patients with excellent and very poor quality-of-life scores in nearly all the quartiles of the corresponding health status domains. CONCLUSIONS: Health status and quality of life represent different outcomes in patients with intermittent claudication. In addition to functional restrictions as measured in health status, quality of life also permits a personal evaluation of these restrictions. Objective functioning and subjective appraisal of functioning are complementary and not identical. Combining these measures should direct treatment in a way that meets patients' needs.

Obesity adversely affects health related quality of life before and after radical retropubic prostatectomy.

PURPOSE: Obesity adversely affects surgical procedures and outcomes. We used a validated health related quality of life measure to examine the effects of obesity on disease specific health related quality of life before and following radical retropubic prostatectomy. MATERIALS AND METHODS: From June 2000 to April 2003, 575 consecutive patients with prostate cancer were approached to participate in a prospective, health related quality of life study. Health related quality of life was assessed before surgery, and 1, 4, 12, 24 and 36 months postoperatively. Repeated measures mixed models were constructed to determine the independent effects of body mass index on health related quality of life. RESULTS: Of 472 consenting subjects 376 (80%) completed a baseline and at least 1 followup survey. Higher body mass index was associated with worse preoperative hormonal/vitality function (p = 0.0009) and bother (p = 0.02), and delayed recovery of bowel function (p = 0.01) and bother (p = 0.01) health related quality of life. There were no measurable differences postoperatively in hormonal/vitality, urinary or sexual health related quality of life associated with higher body mass index. Increased body mass index was associated with prostate specific antigen recurrence (p = 0.05) and adjuvant treatment (p = 0.02). Adjuvant treatment was independently associated with worse bowel function (p = 0.01) and bother (p = 0.01) health related quality of life in obese patients. At 24 months bowel health related quality of life in obese patients no longer significantly differed from that in nonobese patients. CONCLUSIONS: Obesity is associated with worse preoperative hormonal/vitality health related quality of life, slower recovery of bowel function and bother health related quality of life after radical retropubic prostatectomy, and prostate specific antigen recurrence. Impaired health related quality of life recovery in obese patients is influenced by disease recurrence and resultant adjuvant therapies. Despite these findings obese patients should not be dissuaded from considering prostatectomy as definitive treatment for localized prostate cancer.

Reconfirming the role of life events for the timing of depressive episodes. A two-year prospective follow-up study.

BACKGROUND: Since the 1960s the association of stressful life events and depression seemed to be firmly established. However, a few recent studies did not confirm those earlier findings. One of the reasons discussed for the inconsistencies was the sampling of milder depressed neurotic out-patients in the earlier studies vs. more severely ill endogenous type in-patients in recent studies. METHODS: This investigation was carried out with 50 consecutively admitted in-patients with endogenous depression according to ICD 9 and unipolar major depression according to DSM-III-R as ascertained by SCID. The control sample consisted of 26 healthy volunteers. Life events and chronic distressing life conditions were recorded with the Munich Interview for the Assessment of Life Events and Conditions (MEL) every 3 months over a period of 2 years along with psychopathological symptoms and recurrencies. Hence the design was prospective in the sense that life events were recorded for one 3-month cross-section, the depressive reaction for the subsequent one. BDI scores taken at the respective cross section were used to control for depressive bias of the subjective part of the patient's life event evaluation. RESULTS: Three months prior to the index hospitalization patients were more often affected by life events and conditions than controls. The number of stressful conditions prior to the index hospitalization indicated the time to relapse after discharge. Controls showed more desirable positive conditions than patients. Relapse patients suffered more often stressful life events and conditions than non-relapsers 3 months prior to their relapse. Multivariate analysis indicates that the cumulative number of life events within the 2-year course is the best predictor of the BDI score at the end of the follow-up period. LIMITATIONS: Since the subjective component of life event assessment by MEL displayed a higher impact on the course of depression than the objective part of the assessment, confounding of subjective ratings, attributional styles, and depressive symptoms may be a problem although controlled for in this study. CONCLUSION: The results support the importance of stressful life events and chronic distressing conditions for the 2-year course and outcome of major depression in an in-patient sample. Since the overall consistency of significant results was more pronounced in the subjective than in the objective part of the MEL the results fit best a circular pathogenetic model of interactions between life events, their individual evaluation by the patient, and depressive symptoms.

Quality of life in patients on chronic dialysis: self-assessment 3 months after the start of treatment. The Necosad Study Group.

The aim of the present multicenter study was to assess quality of life of Dutch dialysis patients 3 months after the start of chronic dialysis treatment. The quality of life was compared with the quality of life of a general population sample, and the impact of demographic, clinical, renal function, and dialysis characteristics on patients' quality of life was studied. New end-stage renal disease (ESRD) patients who were started on chronic hemodialysis or peritoneal dialysis in 13 dialysis centers in The Netherlands were consecutively included. Patients' self-assessment of quality of life was measured by the SF-36, a 36-item Short Form Health Survey Questionnaire encompassing eight dimensions: physical functioning, social functioning, role-functioning physical, role-functioning emotional, mental health, vitality, bodily pain, and general health perceptions. One hundred twenty hemodialysis and 106 peritoneal dialysis patients completed the SF-36. Quality of life of hemodialysis and peritoneal dialysis patients was substantially impaired in comparison to the general population sample, particularly with respect to role-functioning physical and general health perceptions. Mean role-functioning physical and general health perceptions scores of the hemodialysis patients corresponded with the lowest scoring 8% and 12%, respectively, of the reference group. Mean role-functioning physical and general health perceptions scores of the peritoneal dialysis patients corresponded with the lowest scoring 10% and 12%, respectively, of the reference group. Hemodialysis patients showed lower levels of quality of life than peritoneal dialysis patients on physical functioning, role-functioning emotional, mental health, and pain. However, on the multivariate level, we could only demonstrate an impact of dialysis modality on mental health. A higher number of comorbid conditions, a lower hemoglobin level, and a lower residual renal function were independently related to poorer quality of life. The variability of the SF-36 scores explained by selected demographic, clinical, renal function, and dialysis characteristics was highest for physical functioning (29.7%). Explained variability of the other SF-36 dimensions ranged from 6.9% for general health perceptions to 15.4% for vitality. We conclude that quality of life of new ESRD patients is substantially impaired. Comorbid conditions, hemoglobin, and residual renal function could explain poor quality of life only to a limited extent. Further research exploring determinants and indices of quality of life in ESRD patients is warranted. From a clinical perspective, we may conclude that quality of life should be considered in the monitoring of dialysis patients.

Predictors of quality of life in patients at one year after heart transplantation.

BACKGROUND: A multivariate approach to the study of relationships between quality of life and demographic, physical, and psychosocial variables after heart transplantation has not been examined in a large, multi-site sample. The purpose of this study was to describe quality of life, examine relationships between quality of life and demographic, physical, and psychosocial variables, and identify predictors of quality of life in patients who were 1 year post heart transplantation. METHODS: Data were collected from a nonrandom sample of adult patients (n = 232) who were 1 year post heart transplantation at a Midwestern or Southern medical center. Nine self-administered instruments and chart review were used to gather data from patients. All tools had adequate psychometric support. Descriptive statistics, Pearson correlations, and step-wise multiple regression were used to analyze data. Level of significance was set at 0.05. RESULTS: Patients were most satisfied with the areas of quality of life regarding social interaction and least satisfied with their psychological state. Patients experienced an average amount of stress, were coping fairly well, reported overall good quality of life, and were very satisfied with the outcome of their transplant surgery. Nine out of 16 variables were significant predictors of quality of life and explained 66% of the variance in quality of life: less stress, more helpfulness of information from health care providers, better health perception, better compliance with the transplant regimen, more effective coping, less functional disability, less symptom distress, older age, and fewer complications. CONCLUSIONS: Predictors of quality of life at 1 year after heart transplantation were primarily psychological. Additional variance in quality of life was explained by physical, somatic sensation, demographic, and health status variables. Knowledge of these factors provides (1) information to identify patients who are at risk for poor quality of life at 1 year after heart transplantation and (2) direction for the development of interventions to improve quality of life.

Impact of intermittent claudication on quality of life. The Scottish Vascular Audit Group.

OBJECTIVES: Surgical treatment of intermittent claudication is aimed primarily at improving quality of life, rather than survival. The aim of this study was to examine the impact of claudication on quality of life and the ability of surgeons to judge this. DESIGN AND MATERIALS: 201 claudicants rated their quality of life and completed an SF36 health status questionnaire prior to their first consultation. Following the consultation, the surgeons rated their perceptions of the patients' quality of life. CHIEF OUTCOME MEASURES: SF36 scores were compared with population norms. Multiple linear regression analysis determined the factors influencing quality of life. Agreement between surgeon and patient ratings of quality of life was expressed as a kappa coefficient. MAIN RESULTS: Compared to population norms, claudicants had significantly reduced quality of life in all respects. The severity of disease, as measured by stopping distance, was a significant predictor of general health, pain, vitality and physical and social parameters. Mental and emotional wellbeing were also reduced, but were not related to disease severity. The agreement between patient and surgeon assessments of quality of life was not high (k = 0.4). Patients had a higher perception of their quality of life than their surgeons. CONCLUSIONS: Intermittent claudication impairs quality of life in all respects. The type of treatment offered to patients should reflect their quality of life at presentation, but subjective assessments by surgeons may not be sufficiently accurate. Health status questionnaires have been used almost exclusively in research, but they may also be of use in clinical settings as an objective measure of quality of life.

Life events and depression in a community sample of siblings.

BACKGROUND: The overall aim of the GENESiS project is to identify quantitative trait loci (QTLs) for anxiety/depression, and to examine the interaction between these loci and psychosocial adversity. Here we present life-events data with the aim of clarifying: (i) the aetiology of life events as inferred from sibling correlations; (ii) the relationship between life events and measures of anxiety and depression, as well as neuroticism; and (iii) the interaction between life events and neuroticism on anxiety/depression indices. METHODS: We assessed the occurrence of one network and three personal life-event categories and multiple indices of anxiety/depression including General Health Questionnaire, Anhedonic Depression, Anxious Arousal and Neuroticism in a large community-based sample of2150 sib pairs, 410 trios and 81 quads. Liability threshold models and raw ordinal maximum likelihood were used to estimate within-individual and between-sibling correlations of life events. The relationship between life events and indices of emotional states and personality were assessed by multiple linear regression and canonical correlations. RESULTS: Life events showed sibling correlations of 0-37 for network events and between 0-10 and 0.19 for personal events. Adverse life events were related to anxiety and depression and, to a less extent, neuroticism. Trait-vulnerability (as indexed by co-sib's neuroticism, anxiety and depression) accounted for 11% and life events for 3% of the variance in emotional states. There were no interaction effects. CONCLUSIONS: Life events show moderate familiality and are significantly related to symptoms of anxiety and depression in the community. Appropriate modelling of life events in linkage and association analyses should help to identify QTLs for depression and anxiety.

Response shift in quality of life measurement in early-stage breast cancer patients undergoing radiotherapy.

In medicine, response shift refers to a change--as a result of an event such as a therapy--in the meaning of one's self-evaluation of quality of life. Due to response shift, estimates of side effects of radiotherapy may be attenuated if patients adapt to treatment toxicities. The purpose of our study was to assess to what extent two components of response shift, scale recalibration and changes in values, occur in early-stage breast cancer patients undergoing radiotherapy and to examine what the implications would be for treatment evaluation. In the week before start of post-operative radiotherapy, 46 patients filled out a questionnaire consisting of quality of life items of the SF-36 and the Rotterdam symptom checklist (RSCL) (pretest). During radiotherapy, patients were asked to fill out the questionnaire twice: a posttest (quality of life at that moment) and a thentest (quality of life before treatment, retrospectively), supposedly using the same internal standard. Changes in values were studied by asking the patients on the two occasions to rate the importance of seven attributes representing various domains of quality of life. Patients were also asked whether their quality of life with respect to the measured aspects had changed since the pretest (subjective transition scores). Significant scale recalibration effects were observed in the areas of fatigue and overall quality of life. When the groups were divided according to their subjective transition scores, significant scale recalibration effects were found in case of worsened quality of life for fatigue and overall quality of life, and in case of improved quality of life for fatigue and psychological well-being. The mean importance ratings remained fairly stable over time, except for 'skin reactions', which obtained less importance at the end of radiotherapy than before. In conclusion, effects of scale recalibration were observed that would have significantly affected quality of life evaluations, in that the impact of radiotherapy on fatigue and overall quality of life would have been underestimated. Changes in internal values were observed only for 'skin reactions'.

Negative life events associated with deliberate self-harm in an African population in Uganda.

Negative life events associated with deliberate self-harm (DSH) were investigated in an African context in Uganda. Patients admitted at three general hospitals in Kampala, Uganda were interviewed using a Luganda version (predominant language in the study area) of the European Parasuicide Study Interview Schedule I. The results of the life events and histories module are reported in this paper. The categories of negative life events in childhood that were significantly associated with DSH included those related to parents, significant others, personal events, and the total negative life events load in childhood. For the later-life time period, the negative life events load in the partner category and the total negative life events in this time period were associated with DSH. In the last-year time period, the negative life events load related to personal events and the total number of negative life events in this time period were associated with DSH. A statistically significant difference between the cases and controls for the total number of negative life events reported over the entire lifetime of the respondents was also observed, which suggests a dose effect of negative life events on DSH. Gender differences were also observed among the cases. In conclusion, life events appear to be an important factor in DSH in this cultural environment. The implication of these results for treatment and the future development of suicide interventions in this country are discussed.
