Quality of life as outcome in the treatment of osteoporosis: the development of a questionnaire for quality of life by the European Foundation for Osteoporosis.

The morbidity of osteoporosis is caused by fractures. Vertebral fractures lead to pain and disability and a decrease in quality of life. A Working Party of the European Foundation for Osteoporosis has developed a specific questionnaire for patients with established vertebral osteoporosis. This questionnaire is intended for use in clinical trials. The questionnaire consists of questions and visual analogue scales in the following domains: pain, activities of daily living, jobs around the house, mobility, leisure and social activities, general health perception and mood. The questionnaire has been translated from English into French, German, Italian, Hebrew, Swedish and Dutch. The questionnaire is currently being validated in a multicentre study involving patients with stable osteoporosis and control subjects. Preliminary results indicate that the reproducibility is sufficient and that the questionnaire is able to discriminate between patients with vertebral osteoporosis and control subjects.

Impact of coronary artery bypass grafting on various aspects of quality of life.

OBJECTIVE: To prospectively study the improvement in quality of life (QoL) after coronary artery bypass surgery (CABG). PATIENTS AND METHODS: Consecutive patients (n = 2121) who underwent CABG at Sahlgrenska University Hospital between 1988 and 1991 received 3 questionnaires for the study of QoL: the Physical Activity Score, the Nottingham Health Profile and the Psychological General Well-being Index, which were responded both before surgery and at 3 months (n = 1059), 1 year (n = 1045) and 2 years (n = 1027) postoperatively. RESULTS: All differences were tested against baseline. The Physical Activity Score improved (mean 4.3 before CABG, 3.1, 3 months after (P < 0.0001), and 2.8, 2 years postoperatively (P < 0.0001)). The Nottingham Health Profile score improved (mean 20.5 before CABG, 11.4, 3 months (P < 0.0001), and 10.4, 2 years postoperatively (P < 0.0001)). The Psychological General Well-being Index improved (mean 91.1 before CABG, 103.8, 3 months (P < 0.0001), and 105.8 (P < 0.0001), 2 years after CABG). The subscale analyses of the Nottingham Health Profile and the Psychological General Well-being Index 2 years after CABG showed the greatest improvement in areas reflecting physical capacity and pain, to be followed by mental qualities. At 2 years after CABG only sexual problems were still markedly frequent, and independent predictors for sexual problems after surgery were preoperative problems (P < 0.00001), male sex (P < 0.0001), and diabetes mellitus (P = 0.0008). CONCLUSION: QoL was markedly and significantly improved after CABG. The major improvement was seen already at 3 months, with further slight improvement observed 2 years after surgery. The major improvement was found in areas reflecting physical capacity and pain, which is consistent with symptomatic and objective measurements after CABG. In contrast to the overall improvement in QoL sexual problems were still markedly common 2 years after CABG. The mechanism for this is not fully understood and needs further investigation.

Impact of a history of diabetes mellitus on quality of life after coronary artery bypass grafting.

AIM: To describe the improvement in various aspects of quality of life (QoL) after coronary artery bypass grafting (CABG), in relation to a previous history of diabetes mellitus. PATIENTS: All patients from western Sweden who underwent CABG between 1988 and 1991 without simultaneous valve surgery. METHODS: Patients were approached with three questionnaires: The Physical Activity Score, the Nottingham Health Profile and the Psychological General Well-being Index prior to surgery and 3 months, 1 and 2 years thereafter. RESULTS: All three questionnaires already showed a significant improvement in QoL after 3 months, remaining at a similar level 1 and 2 years after the operation. In terms of Physical Activity Score improvement was of similar magnitude in diabetic and non-diabetic patients. In terms of the Psychological General Well-Being Index significant and similar improvements were found in diabetic and non-diabetic patients at each evaluation. In terms of the Nottingham Health Profile there was a significant improvement both in diabetic and non-diabetic patients 3 months, 1 and 2 years after the operation. However, improvement was more marked in diabetic than in non-diabetic patients at each evaluation. CONCLUSION: For 3 months, 1 and 2 years after CABG various aspects of QoL as estimated with three different instruments, improved significantly both in diabetic and in non-diabetic patients compared with the situation prior to the operation. However, the three instruments differed somewhat. Thus, whereas in the Physical Activity Score, diabetic patients tended to improve less markedly than non-diabetic patients, the opposite was found in the Nottingham Health Profile.

Coronary Artery Bypass↗

Improvement in various estimates of quality of life after coronary artery bypass grafting in patients with and without a history of hypertension.

OBJECTIVE: To describe various estimates of the quality of life (QOL) prior to and for 2 years after coronary artery bypass grafting (CABG) for patients with a history of hypertension compared with nonhypertensives. METHODS: Patients in western Sweden in whom CABG had been performed between 1988 and 1991 participated. Their QOL was estimated from the Physical Activity Score, the Nottingham Health Profile, and the Psychological General Well-being Index. RESULTS: All three questionnaires detected a significant improvement in QOL already at 3 months, which persisted at 1 and 2 years both for hypertensive and for nonhypertensive patients. With the Physical Activity Score and the Psychological General Well-being Index the improvement in QOL of hypertension patients was less marked 3 months after the operation compared with that of nonhypertensives (P < 0.05). Two years after the CABG improvement was less marked for hypertensive patients than it was for nonhypertensive patients in terms of the Physical Activity Score (P < 0.01). With the Nottingham Health Profile the improvement was similar for hypertensive and nonhypertensive patients at each evaluation after the operation. With all three measures the results indicated that hypertensive patients had a worse QOL that did nonhypertensive patients. However, in a multivariate analysis considering other risk indicators simultaneously, a history of hypertension did not appear as an independent risk indicator for an adverse QOL 2 years after CABG. CONCLUSION: There was a significant improvement in various QOL estimates after CABG both for hypertensive and for nonhypertensive patients. The degree of improvement tended to be less marked for hypertensive patients than it was for nonhypertensive patients, especially 3 months after the operation and concerning physical activities. Hypertensives had a worse QOL than did nonhypertensives. However, the differences were small and could mainly be explained in terms of factors other than hypertension.

Does lowering the blood pressure improve the mood? Quality-of-life results from the Hypertension Optimal Treatment (HOT) study.

Nine-hundred-and-twenty-two hypertensive patients were included in a substudy to the Hypertension Optimal Treatment study, which aimed to investigate the impact on quality of life of lowering the pressure and of intensified therapy. Seven-hundred-and-eighty-one patients completed both baseline and follow-up questionnaires (intention-to-treat population), while 610 patients were included in a per protocol analysis. Patients were randomized to three diastolic BP levels (DBPs), i.e. < or =90 mmHg, < or =85 mmHg and < or =80 mmHg. Two self-administered validated questionnaires, the Psychological General Well-Being index and the Subjective Symptoms Assessment Profile (SSA-P) were completed at baseline and after 6 months. The lower the DBP achieved, the greater the improvement in well-being (p < 0.05). The increase in well-being from baseline to 6 months was significant in target groups < or =80 mmHg (p < 0.01) and < or =85 mmHg (p < 0.05). The SSA-P domains, cardiac symptoms and dizziness improved in all groups but the sex life score deteriorated in the < or =80 and < or =85 mmHg groups in male patients. In all target groups, headaches were reduced (p < 0.001), while swollen ankles (p < 0.001) and dry cough in the < or =80 mmHg group (p < 0.001) increased. Although more intensive antihypertensive therapy is associated with a slight increase in subjective symptoms, it is nonetheless still associated with improvements in patients' well-being.

Gender differences in health-related quality of life among postmyocardial infarction patients: brief report. CAST Investigators. Cardiac Arrhythmia Suppression Trials.

Heart disease is the leading cause of death among women in the United States. The prognosis for heart disease is worse for women than for men. Also, although women are less likely than men to initially present with a myocardial infarction (MI), they are more likely to die following an MI. A number of factors have been identified that partially account for the gender difference in post-MI morbidity and mortality. However, limited data are available on the sex differences in clinical, psychosocial, and demographic factors that may combine to explain the poorer prognosis for women following an acute MI. The Cardiac Arrhythmia Suppression Trials collected detailed demographic, clinical, and psychosocial data on 2,043 men and 448 women following acute MIs. Analyses indicate that women had a worse clinical, socioeconomic, and psychosocial profile than did men. In addition, significant differences in psychosocial profiles persisted after controlling for demographic and clinical data, suggesting that women presenting with MIs have a cluster of complex factors that put them at high risk for morbidity and mortality following an MI. Future longitudinal studies that include adequate numbers of women as well as reliable assessments of both clinical and psychological variables are needed to better understand the factors that influence the poor prognosis for women with coronary heart disease.

Improvement in quality of life and exercise capacity after coronary bypass surgery.

BACKGROUND: Outcome after coronary artery bypass grafting is usually evaluated by exercise stress testing. Increased exercise capacity and reduced angina pectoris have been equated with improved quality of life, but this represents a limited view. OBJECTIVE: To prospectively evaluate the effects of coronary artery bypass grafting on quality of life and exercise capacity and their interrelationship. METHODS: In a consecutive series of patients (N = 2365) who underwent coronary artery bypass grafting, we administered a questionnaire to assess quality of life before and 2 years after surgery. A standardized exercise test was performed during the year before surgery and 2 years after. A preoperative exercise test was performed by 726 patients. Among these patients, 462 completed a quality-of-life questionnaire preoperatively and 578 did so postoperatively. Preoperative and postoperative exercise tests were obtained from 362 patients. RESULTS: The improvement in quality of life was related to the severity of preoperative angina (P < .001) and female sex (P = .004) and was inversely related to preoperative exercise performance (P = .04). The improvement in exercise capacity was greater among men (P < .001) and was inversely related to preoperative exercise capacity (P < .001). CONCLUSIONS: The greatest improvement in quality of life after coronary artery bypass grafting appeared in those patients with the most impaired exercise capacity, those with the most severe angina pectoris, and women. Improvement in exercise capacity was greatest in patients with the poorest preoperative exercise capacity and in men. These findings indicate that exercise testing is of limited value as a measure of quality of life and that assessment by a questionnaire has a complementary place.

Validity and reliability of the Spanish version of the Psychological General Well-Being Index.

The Psychological General Well-Being Index (PGWBI) was adapted for use in Spain. The American version was translated and back-translated independently by three bilinguals and the comprehensibility of a consensuated version was tested in a pilot study. The construct validity and internal consistency of the questionnaire were tested in 104 patients (52 high blood pressure patients attending a primary health care centre and 52 end-stage renal disease patients undergoing hemodialysis). Concurrently to the PGWBI, patients were administered the General Health Questionnaire (GHQ-12) and three psychosocial categories of the Sickness Impact Profile (SIP-PD). Patients in the dialysis group were administered the PGWBI on two occasions, two weeks apart. The PGWBI was moderately to highly correlated with the GHQ-12 (r = -0.71) and with the SIP-PD (r = -0.69). Overall internal consistency as measured by Cronbach's alpha coefficient was 0.94. By dimensions, PGWBI alpha coefficients ranged from 0.56 (Self-control) to 0.88 (Anxiety). No differences were found in mean PGWBI scores between the two groups of patients studied. Two-week test-retest intraclass correlation coefficient was 0.76. The similarity of the operating characteristics supports the contention that the Spanish and American versions of the PGWBI are conceptually equivalent. More research is needed on the reliability and responsiveness of the different dimensions of the questionnaire. Our results suggest that only global scores should be used when making individual comparisons.

Quality of life on treatment with metoprolol in dilated cardiomyopathy: results from the MDC trial. Metoprolol in Dilated Cardiomyopathy trial.

Quality of life in heart failure patients is receiving increased attention as a reflection of a treatment's potential secondary benefit of general well-being and daily functioning. The Metoprolol in Dilated Cardiomyopathy (MDC) trial was conducted as a large, multicenter trial to establish the effects of metoprolol on mortality and need for heart transplantation in patients with symptomatic idiopathic cardiomyopathy. It was found that metoprolol was well tolerated, improved symptoms and cardiac function, and prevented clinical deterioration in patients with symptomatic idiopathic dilated cardiomyopathy. Quality of life was evaluated as a secondary endpoint in 345 out of 383 randomized patients using a disease-specific questionnaire, the Quality of Life in Heart Failure Questionnaire, depicting physical activity, somatic symptoms, emotions, and life satisfaction. In a comparison of patients treated with metoprolol or placebo, patients treated with metoprolol noted a significantly more favorable response than those treated with placebo in terms of the overall treatment evaluation (p < 0.05). Additionally, an analysis of the changes from baseline to 18 months, using 95% confidence intervals, revealed that patients treated with metoprolol showed a significant improvement from baseline to 18 months in life satisfaction, physical activity, and the total score, while patients treated with placebo did not change at all. The improvement in quality of life was supported by the correlations with improvement in traditional clinical parameters.

Quality of life assessment after laparoscopic and open fundoplications. Results of a prospective, clinical study.

BACKGROUND: In the evaluation of different treatment alternatives, assessment of the patients' own perceived situation can give important clinical information in addition to the conventional efficacy variables used. METHODS: Fifty patients with chronic gastroesophageal reflux disease (GERD) were operated on with either an open fundoplication (n = 25; 17 men; mean age, 51.5 years) or with a fundoplication through the laparoscope (n = 25; 16 men; mean age, 49.8 years). In each case adequate control of the GERD was achieved with the operation, also when objectively assessed. Twelve months after surgery the quality of life was studied by using a battery of self-administered questionnaires (the Psychological General Well-being (PGWB) index and the Gastrointestinal Symptom Rating Scale (GSRS), and a visual analogue scale, depicting specific reflux-related symptoms (RVAS). RESULTS: After antireflux surgery the overall PGWB scores were normalized with no obvious difference between the two procedures. In the GSRS scale, however, differences were shown between the two procedures, with more dyspeptic and indigestion symptoms in patients having a laparoscopic total fundic wrap. CONCLUSION: These data emphasize the clinical efficacy of antireflux surgery, with normalization of the quality of life in terms of well-being after these procedures. It should be noted that these instruments are sensitive enough to pick up significant differences between different antireflux procedures and should therefore be frequently used in the attempt to refine and optimize long-term therapeutic alternatives in reflux disease.

Psychosocial factors and their role in symptomatic gastroesophageal reflux disease and functional dyspepsia.

Patients with symptoms of GERD and dyspepsia are among the most common consulters in general practice and are different from their counterparts in the community who choose not to consult although they suffer from similar symptoms. They represent a heterogeneous group with considerable symptom overlap. They have a relatively poor quality of life and endoscopic findings can only explain symptoms in about half of these patients. Thus psychosocial factors which could contribute to their morbidity should be explored. While some studies have methodological shortcomings, main findings are that key psychological factors are anxiety, tension, neuroticism, somatization, fears of malignancy, negative assessment of health, depression, a poor social network and less effective coping strategies. Physical illness is likely to bring on psychological distress due to discomfort or threat of ill health. Cognizance of psychosocial factors will facilitate an understanding of the underlying problems and will improve diagnosis and selection of optimal treatment.

Relevance of norm values as part of the documentation of quality of life instruments for use in upper gastrointestinal disease.

This article presents the relevance of norm values to a battery of Quality of Life questionnaires for use in upper gastrointestinal disorders. The derivation of reference values offers an important contribution by confirming the ability of the questionnaires to differentiate patients from healthy controls. Two self-administered questionnaires, the Psychological General Well-being (PGWB) index and the Gastrointestinal Symptom Rating Scale (GSRS) were used. The norm values were derived in a randomly selected sample from a Swedish population consisting of 4624 individuals (reference group). The patients comprised more than 900 patients with gastroesophageal reflux disease (GORD) included in clinical trials. In the reference group, males reported significantly higher values on well-being as compared with women, whereas women reported more pronounced gastrointestinal symptoms than men. Generally, the younger persons and the group aged 60-70 years reported the highest well-being. Among gastrointestinal patients women scored lower and reported more symptoms than men. With increasing age, well-being improved and symptoms declined. Even though the well-being and symptoms scores differed between patient and the reference group similar patterns in terms of age and gender were observed. In summary, the results show that there are differences with respect to gender and age among normal controls as well as in GORD patients. These aspects have to be considered in clinical studies. The results also support the discriminative ability of the Quality of Life instruments.

Quality of life: a reflection of symptoms and concerns.

BACKGROUND: Upper gastrointestinal complaints are common in the general population. Most patients consulting have no or only minimal markers of disease. It is important to evaluate new methods for the assessment and follow-up of treatment of these new patient groups. METHODS AND RESULTS: Recent publications on Quality of Life (QOL) and upper gastrointestinal disease are reviewed with the specific aim of relating the effect of disease symptoms and patient concerns to the outcome of investigations. We found that QOL is adversely affected in upper gastrointestinal disorders and that effective treatment medically or surgically normalizes the scores. There is a good correlation between degree of symptoms and QOL outcome. Patients' concern affects the outcome. CONCLUSION: QOL assessments are helpful in evaluating the impact of upper gastrointestinal disease.

Quality of life and regulatory issues.

Since Quality of Life is increasingly more often used as a therapeutic endpoint in clinical trials, it is essential that the same level of scientific rigour is applied to these assessments. The draft guidelines issued by the Food and Drug Administration as well as with the Common Market are therefore welcomed.

The development of a European questionnaire for quality of life in patients with vertebral osteoporosis.

The complaints of vertebral osteoporosis usually result from wedge or crush fractures and biconcave deformities. These are caused by a decrease of bone mass and deterioration of bone structure leading to loss of strength. Treatment of osteoporosis should result in an increase of bone mass, and the incidence of new vertebral fractures should diminish. However, new vertebral fractures are not always accompanied by pain, and disability does not well correlate with the number of vertebral fractures. Patients with osteoporosis often have other problems e.g. with taking a shower, preparing meals, gardening, walking stairs, visiting friends and attending social activities. In addition, pain and disability may influence mood and lead to depression. The assessment of quality of life should be a primary endpoint in clinical trials in patients with osteoporosis and in individual patients care. Recently, the European Foundation for Osteoporosis (EFFO) has decided a develop a questionnaire for patients with vertebral osteoporosis, i.e. patients with vertebral deformities. The questionnaire is meant for use in clinical trials. A questionnaire was made including 48 questions and 6 visual analogue scales. The questions concern the following domains: pain, activities of daily living, jobs around the house, moving, leisure and social activities, general health perception and mood. The questionnaire ("Qualeffo") has now entered the validation phase. The first study in 8 centres concerns the within-subject reproducibility, the internal coherence, and the specificity by comparing osteoporotic patients with a control group not suffering from osteoporosis or backpain.

Effects of 12 weeks of ramipril treatment on the quality of life in patients with moderate congestive heart failure: results of a placebo-controlled trial. Ramipril Study Group.

The assessment of quality of life (QoL) has become recognized as an important tool for evaluating heart failure therapy. The angiotensin-converting enzyme inhibitor ramipril (mean dose 8 mg) was evaluated in 223 patients with moderate chronic congestive heart failure at 24 centers in 4 Nordic countries following a randomized, double-blind, placebo-controlled, parallel group design. The follow-up period was 12 weeks. QoL was evaluated using a questionnaire with 47 items, including the disease-specific Severe Heart Failure Questionnaire, the Sleep Dysfunction Scale, and the Psychological General Well-Being Index. In both treatment groups the total score increased from baseline to 12 weeks for both the Severe Heart Failure Questionnaire and for the Psychological Well-Being Index, reflecting relief of symptoms and improved well-being. However, no significant differences between the placebo and ramipril groups could be detected. Only a trend toward improvement in sleep on ramipril compared with placebo therapy was observed. In conclusion, in this placebo-controlled trial no significant effects of 12-week ramipril treatment of QoL could be demonstrated in patients with moderate congestive heart failure.
