Quality-of-life assessment in osteoporosis: health-status and preference-based measures.

Health-status and preference-based approaches to assessing health-related quality of life (HR-QOL) in osteoporosis are reviewed. Osteoporosis-targeted health-status instruments [i.e. Osteoporosis Quality-of-Life Questionnaire (OQLQ), Osteoporosis Assessment Questionnaire (OPAQ), Quality-of-Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO), Osteoporosis-Targeted Quality-of-Life Questionnaire (OPTQoL), Osteoporosis Functional Disability Questionnaire (OFDQ), Quality-of-Life Questionnaire in Osteoporosis (QUALIOST)], which have been utilised to document the adverse impact of osteoporosis on HR-QOL in diverse clinical and epidemiological studies, are described first. Preference-based approaches to osteoporosis health-outcome measurement are then considered in both clinical and health policy settings. In the clinical setting, direct preference assessments [i.e. visual analogue scale (VAS), time tradeoff (TTO), standard gamble (SG)] using either experienced or described health outcomes have consistently shown significantly lower values for osteoporosis-related health states relative to usual or ideal health. In the health-policy context, preference-classification systems [i.e. EuroQoL (EQ-5D), Health Utilities Index (HUI)] for valuing health in economic studies are reviewed. At present, there is little evidence to guide the choice of one system over another for assessing the cost effectiveness of osteoporosis interventions; however, use of a consistent set of health-state values is essential. Further research is needed to characterise associations between osteoporosis-targeted health-status instruments and preference-based health-outcome measures. In addition, the longitudinal impact of osteoporosis and related fractures on HR-QOL must be documented.

[Health status indicators and the importance of their use in daily practice].

Health information undoubtedly has great social, political and economic importance. To have relevant information, it means to have basis for timely reporting, basis for action, and prerequisites for success. The purpose is to produce and use adequately appropriate information about health status, health risks and health outcomes in order to establish priorities. Health information should be useful and easy accessible to all potential users in every moment, from health care providers to the general public. Health indicators, as aggregated health statistical data, present measure instruments in this process, and because of that definition, development and implementation of basic set of health indicators at all levels (public health and clinic) must be the priority activity in the current moment of health sector reform in Bosnia and Herzegovina. Basic set of relevant and measurable indicators should be founded on different aspects of health and health care (health promotion, diseases prevention, clinical treatment, rehabilitation), monitoring and evaluation as a part of everyday's routine in health sector.

Self-reported health status of the general adult U.S. population as assessed by the EQ-5D and Health Utilities Index.

OBJECTIVE: This study aimed to describe the self-reported health status of the general adult U.S. population using 3 multi-attribute preference-based measures: the EQ-5D, Health Utilities Index Mark 2 (HUI2), and Mark 3 (HUI3). METHODS: We surveyed the general adult U.S. population using a probability sample with oversampling of Hispanics and non-Hispanic blacks. Respondents to this home-visit survey self-completed the EQ-5D and HUI2/3 questionnaires. Overall health index scores of the target population and selected subgroups were estimated and construct validity of these measures was assessed by testing a priori hypotheses. RESULTS: Completed questionnaires were collected from 4048 respondents (response rate: 59.4%). The majority of the respondents were women (52.0%); the mean age of the sample was 45 years, with 14.8% being 65 or older. Index scores (standard errors) for the general adult U.S. population as assessed by the EQ-5D, HUI2, and HUI3 were 0.87 (0.01), 0.86 (0.01), and 0.81 (0.01), respectively. Generally, younger, male and Hispanic or non-Hispanic black adults had higher (better) index scores than older, female and other racial/ethnic adults; index scores were higher with higher educational attainment and household income. The 3 overall preference indices were strongly correlated (Pearson's r: 0.67-0.87), but systematically different, with intraclass correlation coefficients between these indices ranging from 0.59 to 0.77. CONCLUSIONS: This study provides U.S. population norms for self-reported health status on the EQ-5D, HUI2, and HUI3. Although these measures appeared to be valid and demonstrated similarities, health status assessed by these measures is not exactly the same.

The Innsbruck Women's Health Study 1999: health status and behaviour.

OBJECTIVES: The aim of this study is to report descriptive results of a recent survey on women's health and to analyse associations between perceived health status and health behaviour. METHODS: A cross-sectional survey on 609 women aged 20 to 95 years was performed in Innsbruck (Austria) in 1999. RESULTS: Self-reported poor health status was 6% in the 20-39 age group, 10% in the 40-59 age group and 20% in the 60 and older age group. Age and physical activity were significant predictors for health status. Women who performed physical activities on a regular basis had a more than 70% reduced risk of poor health status. Concerning the prevalence of self-reported morbidity, urogenital disorders (35%), allergies (32%), and headache (42%) were most frequent in younger women whereas skeletal disorders such as rheumatic diseases (41%), osteoporosis (39%), and invertebral disc damage (39%) in older women. Important health behaviour-related problems to be found were 40% smoking among women under 40, and 42% overweight or obesity among women over 60. Stress affected 37% of women under 60 years of age. CONCLUSIONS: Physical activity, smoking, overweight and stress revealed to be key-indicators for improving women's health.

A model of health status for rheumatoid arthritis. A factor analysis of the Arthritis Impact Measurement Scales.

Health status is a key aspect of quality of life that may be addressed and affected by health care. The measurement of this construct requires the identification of unique and relevant components of health status that can be operationally defined by specific scales or scale groupings. We explored the components of health status that are operationalized by the Arthritis Impact Measurement Scales (AIMS). Prior testing has shown that the AIMS measures delineate at least 3 components of health status: Physical Function, Psychological Status, and Pain. This 3-component model, however, can be theoretically and empirically restrictive. Using AIMS responses from a rheumatoid arthritis (RA) patient population, our investigation, through factor analyses, identifies 5 components of health status in this chronic disease: Lower Extremity Function, Upper Extremity Function, Affect, Symptom, and Social Interaction. It is proposed that these intuitively reasonable and measurable components constitute the core of the health status construct for individuals with RA. These 5 components could also prove central to the assessment of health status in other rheumatic diseases. Future studies of health status in RA should include tested measures to assess these 5 components.

Disease course in systemic lupus erythematosus: changes in health status, disease activity, and organ damage after 2 years.

OBJECTIVE: To examine changes in health status, disease activity, and organ damage after 2 years and to study possible disease variables predicting change in health status, disease activity, and organ damage at followup in systemic lupus erythematosus (SLE). Second, to compare changes in health status in patients with SLE to that of matched patients with rheumatoid arthritis (RA) and matched healthy controls. METHODS: A 2 year longitudinal observational study, measuring health status (Short-Form 36. visual analog scale for pain and fatigue, modified Health Assessment Questionnaire, patient global assessment of disease activity), disease activity, and organ damage in 87 patients with SLE. Health status measures in SLE were compared to 65 matched RA patients selected from the Oslo RA register and to 77 matched healthy controls from the population register. RESULTS: On a group level the SLE patients showed stable health status measures and disease activity scores 2 years after baseline, but organ damage scores increased significantly. Increase in organ damage was significantly and independently predicted by baseline scores of disease activity and organ damage, health status, and disease activity by the respective baseline scores. Changes in health status measures over 2 years were similar in SLE, RA, and healthy controls. CONCLUSION: Our 2 year longitudinal observational SLE study showed a stable course of health status and disease activity, whereas organ damage increased. Disease activity and organ damage at baseline predicted the latter. Our results indicate the value of careful monitoring of disease activity over time in SLE and individually tailored treatment guided by the predictors of course and outcome.

Examining emotional, physical, social, and spiritual health as determinants of self-rated health status.

PURPOSE: To determine whether individuals' perceptions of their emotional, physical, social, and spiritual health constitute elements of their self-rated health status operationalized with a commonly employed single indicator. DESIGN: Secondary analysis of cross-sectional survey data. Structural equation modeling with LISREL was used. SETTING: The Yukon Health Promotion Survey, Yukon Territory, Canada, 1993. SUBJECTS: The population-based sample was made up of 742 women and 713 men between 15 and 90 years of age; 80.3% responded. MEASURES: Self-rated health status was operationalized with the "excellent, good, fair, poor" indicator derived from the question: "In general, compared to other people your age, would you say your health is...." Social, spiritual, emotional, and physical health status were also self-rated from excellent to poor. RESULTS: The model's fit of the data was acceptable. Only physical health status significantly contributed to the variance in self-rated health status (55.1% of the variance was explained). Emotional, social, and spiritual health were found to have no effect on individuals' ratings of their health status. CONCLUSIONS: Although recent conceptualizations have broadened in much of the theoretical and political discourse about health, especially in health promotion, the self-rated health status indicator measures only physical health status.

Health status of Victorian special school children.

OBJECTIVE: This study sought to determine the health status and health needs of a sample of students attending special schools for the intellectually disabled in Victoria, Australia. METHODOLOGY: Two hundred and forty-nine students not previously seen by a Community Child Health Medical Officer (CCHMO) were assessed at school. Data on student, parent and staff needs were obtained through personal interviews and documented on a standard questionnaire. Health status was documented using data obtained from parents and teachers as well as the clinical assessment. RESULTS: Comparison of the number of problems reported by parents with the number confirmed at examination showed significant underreporting of vision, hearing and general medical problems. However, behaviour problems were nearly all reported. Many students had multiple problems with 63% having 2-4 problems and 11% having 5-8 problems. Ninety-nine (40%) of the 249 children seen had newly detected problems; vision (24), hearing (24) and obesity (9) were the most common. Two hundred and forty-four (98%) had known problems and 27% of these had insufficient information available from parents or staff to completely ascertain their health status. In 115 cases the primary problem was intellectual impairment of unknown cause. Down's syndrome was the next most common underlying diagnosis (30) followed by autism (24), epilepsy (21) and cerebral palsy (15). The most common secondary diagnoses were asthma (16), congenital heart defects (12), seizures (8) and skin problems (8). Many students required referral for further management both for newly detected problems (64%) and known problems (18%). Parents required counselling and/or discussion on a number of issues for both newly detected problems (66%) and known problems (39%); when counseling had taken place parent and staff concerns had reduced significantly by the time of the follow-up assessment. CONCLUSIONS: This study demonstrates that in those students with known intellectual impairment there were many with other unrecognized health problems and unmet needs. These findings have implications for health services provided to children attending special schools.

The quality of health data obtained in a new survey of elderly Americans: a validation study of the proposed Medicare Beneficiary Health Status Registry (MBHSR).

The Medicare Beneficiary Health Status Registry (MBHSR) is a proposed new survey program that would collect health status indicators annually from large probability samples of Medicine beneficiaries. For reasons of economy, the MBHSR would use mail survey procedures with telephone follow-up of nonrespondents. Because of concerns about response rates and the validity and reliability of the data obtained by such methods, a large-scale (N = 1,922) field test was conducted. The field test assessed the validity of MBHSR survey reports of past medical treatment and conditions by comparing those reports with Medicare claims data. It assessed the (internal) reliability of MBHSR survey responses by comparing responses with logically related survey questions from the MBHSR. Analyses indicate that the MBHSR survey procedures using a combination of mail data collection with telephone follow-up of nonrespondents produced relatively high levels of sensitivity and specificity in identifying medical treatments and procedures previously recorded in Medicare claims data. In addition, the MBHSR Field Test obtained, in general, relatively high levels of internal consistency in survey reports.

Health status in systemic lupus erythematosus compared to rheumatoid arthritis and healthy controls.

OBJECTIVE: To examine health status in systemic lupus erythematosus (SLE), using both generic and arthritis-specific instruments, and compare the health status in patients with SLE to matched patients with rheumatoid arthritis (RA) and matched healthy controls. As well, to study possible correlations between health status measures and demographic and disease variables in the patients with SLE. METHODS: Patients were recruited from the Oslo county registers of patients with SLE and RA, and the healthy controls from the county population register. Measures of health status (Medical Outcome Survey SF-36, joint pain and fatigue on visual analog scale, Modified Health Assessment Questionnaire) were obtained from 82 SLE and 82 RA patients matched for age, sex, and disease duration, and from 74 age and sex matched healthy controls. Disease activity and organ damage were assessed in the patients with SLE. RESULTS: Patients with SLE were significantly more affected in all dimensions of health status compared to controls, except in the SF-36 category role-emotional. Further, patients with SLE were significantly less affected than patients with RA with regard to physical function and joint pain, but scores were similar in all other dimensions of health status. Scores of health status correlated more strongly to the damage index than to disease activity, indicating that health status measures capture some of the same concept as the damage index, namely the consequence of the disease over time. CONCLUSION: Our study showed that patients with SLE and RA have a multidimensional involvement of health status compared to healthy controls. The findings call for a biopsychosocial approach in the management of SLE.

Relation between symptoms of depression and health status outcomes in acutely ill hospitalized older persons.

BACKGROUND: Older patients often have poor health status outcomes after hospitalization. Symptoms of depression are common in hospitalized older persons and may be a risk factor for these poor outcomes. OBJECTIVE: To determine whether symptoms of depression predict worse health status outcomes in acutely ill, older medical patients, independent of health status and severity of illness at hospital admission. DESIGN: Prospective cohort study. SETTING: Medical service of a teaching hospital. PATIENTS: 572 hospitalized medical patients older than 70 years of age. MEASUREMENTS: 15 symptoms of depression, health status, and severity of illness were measured at admission. The main outcome was dependence in basic activities of daily living at discharge and 30 and 90 days after discharge. Other outcome measures were dependence in instrumental activities of daily living, fair or poor global health status, and poor global satisfaction with life. RESULTS: The median number of symptoms of depression on admission was 4. Patients with 6 or more symptoms on admission (n = 196) were more likely than patients with 0 to 2 symptoms (n = 181) to be dependent in basic activities of daily living (odds ratio, 2.47 [95% CI, 1.58 to 3.86]) after controlling for demographic characteristics and severity of illness. At each subsequent time point, patients with more symptoms of depression on admission were more likely to be dependent in basic activities of daily living. This association persisted after adjustment for dependence in basic activities of daily living, severity of illness, and demographic characteristics on admission. The odds ratios comparing patients who had 6 or more symptoms with those who had 0 to 2 symptoms were 3.23 (CI, 1.76 to 5.95) at discharge, 3.45 (CI, 1.81 to 6.60) 30 days after discharge, and 2.15 (CI, 1.15 to 4.03) 90 days after discharge. At each time point, patients with 6 or more symptoms of depression were more likely to have more dependence in instrumental activities of daily living, worse global health status, and less satisfaction with life. CONCLUSIONS: Symptoms of depression identified a vulnerable group of hospitalized older persons. The health status of patients with more symptoms of depression was more likely to deteriorate and less likely to improve during and after hospitalization. This association was not attributable to health status or severity of illness on admission. The temporal sequence and magnitude of this association, its consistency over time with different measures, and its independence from the severity of the somatic illness strongly support a relation between symptoms of depression on admission and subsequent health status outcomes.

The changing landscape for the elimination of racial/ethnic health status disparities.

The elimination of racial/ethnic health status disparities is a compelling national health objective. It was etched in sharp relief by the 1985 report of the U.S. Department of Health and Human Services Secretary's Task Force on Black and Minority Health and considerable attention has been devoted to the problem since that report. But the problem persists, disparities are not fully explained and effective policies to reduce them have been elusive, a situation presenting both opportunities and challenges. Important advances towards reducing racial/ethnic health disparities may be made by better understanding the complex bidirectional relationship between and among the multiple factors, biological and non-biological, influencing morbidity and mortality. The landscape in which these influences are felt is anything but static. In this paper selected components of the landscape that are critical to the elimination of racial/ethnic health status disparities are reviewed. These factors underscore the importance of adopting and maintaining a perspective on health disparities that encompasses a broad array of health determinants.

Health status assessment in a hypertension section of an internal medicine clinic.

The authors obtained health status instrument information with the SF-36 and COOP charts distributed in random order (along with selected items from the Hypertension Technology of Patient Experience [TyPE] tool) to patients attending the hypertension section of an internal medicine clinic. The goal was to examine and compare potential associations of clinical, demographic, and/or treatment variables with SF-36/COOP health status scale variables in a nonuniversity urban clinic. One hundred fifty-eight pairs of health status instruments were returned (62% response rate). One hundred (64%) had a diagnosis of hypertension, 81 (51%) were males, 94 (60%) were older than 65 years, and 122 (78%) were white. Clinical, demographic, and treatment measurements were studied using regression analysis; the estimated regressions accounted for 4-32% of the variation in the COOP scales and 8-19% in the SF-36 scales. The number of coexisting diseases, gender, and diagnosis of hypertension were the most frequent significant variables associated with health status scale outcomes for each health status instrument. For most COOP and some SF-36 scales, there was a significant hypertension by gender interaction indicating that women with a hypertension diagnosis report better health status than women seen for other conditions; hypertension diagnosis had little effect on men's reported health status for most scales. Further study is necessary to confirm these results, yet the regression models developed in this study suggest that health status as assessed by these instruments is affected by multiple and not always obvious factors.

Patient self-efficacy and health locus of control: relationships with health status and arthritis-related expenditure.

OBJECTIVE: To explore the relationship between measures of self-efficacy, health locus of control, health status and direct medical expenditure among community-dwelling subjects with rheumatoid arthritis (RA) and osteoarthritis (OA). METHODS: This analysis is part of a larger ongoing study of the costs and outcomes of arthritis and its treatments. Community-dwelling RA and OA respondents completed questionnaires concerning arthritis-related expenditure, health status, arthritis related self-efficacy and health locus of control. RESULTS: Data were obtained from 70 RA respondents and 223 OA respondents. The majority of respondents were female with a mean age of 63 yr for RA respondents and 68 yr for OA respondents. Among the RA respondents, those with higher self-efficacy reported better health status and lower overall costs. Health locus of control was not consistently correlated with health status. OA respondents with higher self-efficacy reported better health status and lower costs. Health locus of control had more influence. OA respondents with higher external locus of control reported worse pain and function. A higher belief in chance as a determinant of health was correlated with more visits to general practitioners and a higher cost to both the respondent and the health system. CONCLUSION: Higher self-efficacy, which is amenable to change through education programmes, was associated with better health status and lower costs to the respondent and the health system in this cross-sectional study. Locus of control had less of an influence; however, the tendency was for those with higher external locus of control to have higher costs and worse health status. As the measurement of these constructs is simple and the outcome potentially affects health status, these results have implications for future intervention studies to improve quality of life and reduce the financial impact of arthritis on both the health-care system and patients.

Predictors of elderly mortality: health status, socioeconomic characteristics and social determinants of health.

This paper uses longitudinal survey data from Taiwan to investigate the predictors of elderly mortality. The empirical analysis confirms a relationship between socioeconomic characteristics and mortality, but this relationship weakens considerably when estimates are conditional on the health status at the time of the first wave survey. In terms of predictive power, the models with an activities of daily living index fare better (as opposed to models with self-evaluated health or self-reported illnesses). Having said that there is a payoff to the consideration of self-evaluated health jointly with other 'objective' health indicators. Other findings include a strong association between life satisfaction and survival, which prevails even after controlling for other explanatory variables.

Association between physical health status with selected factors.

A study, to determine the physical health status of children between the age of three to five years and its association with selected factors, was conducted in a village of Udupi district of Karnataka state in 1998. The objectives of the study were to assess the physical health status of children between the age of three and five years, to identify the selected factors under study like employment status of parents, age of parents, educational status of parents, birth order of the child, number of siblings of the child, gender of the child, child care arrangements and socio-economic status of parents and to find out the association between physical health status of children between the age of three and five years and selected factors. The study used system's model. Co-relational survey approach was used and data were collected from 100 samples. Tools were developed by the investigator and purposive sampling was used for selection of sample elements. A significant association was observed between the physical health status of the children and the employment status of the mother [chi square = 4.003, p < 0.05], and no significant association was found between physical health status and age of parents, educational status of parents, birth order of the child, number of siblings of the child, gender of the child, child care arrangements and socio economic status of parents.

Socio-demographic variables are limited predictors of health status in multiple sclerosis.

BACKGROUND AND OBJECTIVES: Self-reported health status measures reflect disease impact from the patient's perspective. However, such measures are not designed for individual patient use and are rarely used to guide clinical practice. Nevertheless, if strong predictors of health status can be demonstrated in large datasets, these could be used to identify people at risk of poor health states and help target interventions. The aim of this study was to examine the predictive value of routinely collected socio-demographic variables on health status. METHOD: Data for 638 patients with multiple sclerosis (MS) on the eight health dimensions of the Medical Outcomes Study 36-item Short Form Health Survey (SF-36) were collected either by a postal survey or hospital attendance and analysed by multiple regression analyses. RESULTS: Several sociodemographic variables, such as unemployment and manual social class had some predictive value on health status, but the effect was not strong (maximum cumulative variance explained 53 %). CONCLUSIONS: Sociodemographic variables that we studied were limited predictors of health status in MS and are of limited value in guiding clinical practice.
