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.

Strategies for improving and expanding the application of health status measures in clinical settings. A researcher-developer viewpoint.

Health status instruments may be useful in clinical settings to screen for functional problems, monitor disease progression or therapeutic response, improve doctor-patient communications, assess quality of care, or provide case-mix adjustment for comparing other outcomes between patient groups. However, conceptual, practical, and attitudinal barriers have prevented their wider implementation. Aside from providing more data on how these measures influence the process and outcomes of clinical care, several strategies may help to improve and expand their application. Wider application would be promoted by training health care providers about the methods of health status assessment, their validity, and the available instruments; comparing newer functional measures and older scales with which clinicians are familiar (to make scores more meaningful); providing better data for the selection of instruments; and improving the responsiveness of these questionnaires to clinical changes. If health status measures are used in direct patient care, it is important to determine whether the goal is to screen for functional problems or to monitor patient changes over time. These different purposes may influence the selection of instruments, the types of patients targeted (e.g., based on age or diagnosis), and the frequency of patient assessment. Health status measures must be easily incorporated into the office routine, requiring that they be brief, easy to interpret, and not require complex training or scoring algorithms. In this setting, it may be helpful to provide clinicians not only with functional status scores, but with interpretations and recommendations about management or community resources to consider. The costs of health status measurement and data analysis will probably be borne by third-party payers, who must be persuaded of their utility. When health status measures are used for quality assurance, average scores for groups of patients should be adjusted for disease severity, comorbid conditions, demographic characteristics, socioeconomic status, and baseline health status. Furthermore, the sickest or most vulnerable members of a clinical population may be least able to provide valid health status information because of dementia, frailty, blindness, illiteracy, or inability to speak English. These patients may be of particular interest, and are likely to alter average health status scores for a population, so methods to assure complete ascertainment must be considered.

Alcohol dependence: the impact of cognitive behaviour therapy with or without naltrexone on subjective health status.

OBJECTIVES: To examine the health-related quality of life of alcohol-dependent patients across a 12-week cognitive behaviour treatment (CBT) program and identify whether the patient selection of the anticraving medication naltrexone further enhanced these outcomes. METHOD: One hundred and thirty-six consecutive alcohol-dependent subjects voluntarily participated and were offered naltrexone, of which 73 (54%) participants declined medication. A matched design was used. Of the 136 subjects, 86 (43 naltrexone and CBT; 43 CBT only) could be individually matched (blind to outcome measures) for gender, age, prior alcohol detoxification and dependence severity. Measures of health status and mental health wellbeing included the Rand Corporation Medical Outcomes Short Form 36 Health Survey (SF-36) and the General Health Questionnaire (GHQ-28). RESULTS: Pre-treatment, all had SF-36 and GHQ-28 scores markedly below national norms. Post-treatment, significant improvement in seven of the eight SF-36 subscales and all of the GHQ-28 subscales occurred, approximating national normative levels. Patients in the CBT + naltrexone group were significantly more likely to have increased days abstinent (p=0.002) and to complete the program abstinent (p=0.051). The adjunctive use of naltrexone did not provide additional benefit as reflected in SF-36 and GHQ-28 scores, beyond CBT alone. CONCLUSIONS: Patients who completed the CBT-based treatment program reported significant improvements in self-reported health status (SF-36) and wellbeing (GHQ-28). The adjunctive use of naltrexone demonstrated no additional improvement in these measures.

Validation and normative data of health status measures in older people: the Islington study.

BACKGROUND: Health related quality of life scales have been developed to measure a global picture of health and well-being from the patient's perspective. Separate validation of these measures in older people is important, as different areas of life are prioritized as important in older people and population norms for health status measures can differ with age. OBJECTIVES: The aims of this paper were to examine the validity and acceptability of two health status measures the 12-item Health Status Questionnaire (HSQ-12) and 12-item Short Form Health Survey SF-12, and to present population norms in older people. SETTING: A door-to-door survey in Islington, a borough of inner London. SUBJECTS AND METHODS: The subjects were allocated to complete either the SF-12 (n = 541) or the HSQ-12 (n = 544) by alternating the questionnaires with each household visited. The first 135 people who completed the HSQ-12 were visited approximately 18 months later. Acceptability was measured examining the completion rate of the scales, and on a three-point scale. The short-CARE was used to elicit psychiatric symptoms and diagnoses. We collected data on health and social care, and subjective health problems. RESULTS: Both scales distinguished between subjects with and without a variety of health states, including self-defined health problems, health problems diagnosed by valid scales, problems with vision and hearing, and receipt of health or social services. The HSQ-12, but not the SF-12, could distinguish between people with and without dementia, and had high completion rates for those living in the community but not in 24-hour care. Linear regression models demonstrated sensitivity to change in health status for the HSQ-12. CONCLUSION: The SF-12 and HSQ-12 are acceptable and valid as health status instruments in large community-based studies of older people. The HSQ-12, but not the SF-12, is acceptable and valid for people with dementia.

African American women's health self-assessment: health status and the sense of coherence.

This descriptive study examines the relationship between health self-assessment, health status, and the sense of coherence (SOC) in a random sample of 48 African American women. Sense of coherence and health status were measured by Antonovsky's Orientation to Life Questionnaire and the Perception of Health Status Scale, respectively; health self-assessment was determined by placement on a rung of the Cantril ladder. Women who viewed their current health status as devoid of acute, chronic, or serious health problems had a significantly stronger SOC than those with serious, chronic, and degenerating health problems. Generally, women did not differ on the meaningfulness they attached to their lives based on their health status; however, women with no acute health concerns and those with serious health problems differed significantly on this subscale. The women's SOC was significantly different based on the amount of pain being experienced, particularly on the manageability scale, indicating their inability to handle pain. The women's overall health self-assessment was negatively related to their SOC. A strong SOC was negatively related to two dimensions of health status: perception of pain and current health status. A strong SOC was negatively related to overall health status. Implications to promote the health of African American women are discussed.

Using composite health status measures to assess the nation's health.

Research in progress at the National Center for Health Statistics for evaluating the usefulness of composite measures of health status for assessing the nation's health is described. Three measures suitable for use in the general population, the Health Insurance Experiment-Functional Limitations (HIE-FL), the Health Utility Index (HUI), and the Quality of Well-being (QWB) scale, have been mapped to data collected in the 1980 National Health Interview Survey (NHIS). Analysis using current algorithms for making composite function status measures according to the QWB methods suggests that traditional single indicators of health tend to overestimate the level of health by about 10%. When symptoms and problems are added to the composite function score, the overestimate as measured by the single indicator is at least 50%. The authors are continuing to validate these algorithms, to develop similar ones for the HIE-FL and HUI, and to extend the analysis to data collected in 1977, 1979, and 1984. Current results indicate that to realize fully the benefits of composite measures, well-established, valid, and reliable measures of health-related quality of life should be included as part of the regular NHIS data collection procedures.

Assessment of the impact of cancer on work, recreation, home management and sleep using a general health status measure.

A general health status measure (the UK Sickness Impact Profile) was used to assess health-related quality of life in 212 cancer patients [143 women, mean (SD-standard deviation) age 55.3 (11.7) years] compared to 105 age-sex matched control subjects [71 women, mean (SD) age 54.7 (12.2) years]. The four main areas of impairment in the cancer patient group were work, recreation and pastimes, home management and sleep and rest. The majority of patients were unable to work or working shorter hours due to their disease. A diagnosis of cancer was likewise found to have a major impact on active leisure pursuits and led to reduced participation in social and community activities. Patients had particular problems in carrying out household chores and maintenance or repair work in the house. Many patients had difficulty sleeping at night and tended to sleep during the day or rest for much of the day. The majority of studies of quality of life in oncology patients concentrate upon alterations in symptoms, such measures would fail to detect impairment in the aspects described above. Greater attention should be directed towards addressing issues such as changes in employment status and the need for help in the home to improve the overall care of cancer patients.

Ulcerative colitis and Crohn's disease health status scales for research and clinical practice.

We report the development of ulcerative colitis (UC) and Crohn's disease (CD) Health Status Scales that improve on existing inflammatory bowel disease (IBD) activity measures by their added association with health status. We surveyed 991 members of the Crohn's and Colitis Foundation of America (CCFA) and analyzed the half with greater disease activity (114 UC, 330 CD, ostomies excluded). Our analysis strategy involved (a) identification of items that discriminated active from inactive disease, (b) factor analysis to reduce the items to clusters sharing common symptom relationships, and (c) regression analysis to select those variables best associated with a composite measure of health status (health care use, daily function, psychologic distress). The factor analyses yielded two indexes for UC and CD: "Diarrhea," and "Other GI symptoms" (Cronbach's alpha 0.59-0.84). The regression analyses for both diseases showed that poorer well-being, the Diarrhea index, and dependence on medication for pain were associated with poorer health status. For UC, lower educational attainment and lower steroid dose, and for CD, the Other GI symptoms index and eye disease, also correlated with poorer health status. By design, the UC and CD Scales are better predictors of health status than the survey version of the CD Activity Index (CDAI), explaining 17 and 21% more of the variance of the health status measure. The final UC and CD Health Status Scales can be used in research and clinical care. They contain symptom items used to assess disease activity and also correlate with health status. Prospective assessment is needed to confirm their accuracy in assessing prognosis and treatment response.

[The results of a comprehensive evaluation of the health status of the population, of public health resources and of the socioeconomic status of the territories of the Russian Federation].

Population health in the Russian Federation was assessed over the course of 5 years using a universal method with ranking of territories according to Euclidian distance, which is a variant of cluster analysis. The same method was used in study of the ratio of territories as to their provision with public health resources and some resultant socioeconomic parameters. Under condition of the socioeconomic crisis involving the whole country, the population health rapidly reacted to changes by developing new and progress of the existing negative tendencies, which led to shift of some territories, particularly of the Northern ones, in the ranked series. As a rule, there are more problems with population health at territories with more strained socioeconomic situation.

Health insurance and subjective health status: data from the 1987 National Medical Expenditure survey.

OBJECTIVES: The relationship between health insurance and subjective health status was investigated. It was hypothesized that persons without health insurance would have lower levels of subjective health status than those with health insurance and that this relationship would hold for both poor and nonpoor persons. METHODS: Data from the 1987 National Medical Expenditure Survey were analyzed to examine the relationship between health insurance and self-reported health status. The analysis controlled for sociodemographic and attitudinal variables and medical conditions. RESULTS: Persons without health insurance had significantly lower levels of subjective health status than did persons with insurance. This adverse effect persisted after adjustments were made for the effects of age, sex, race, income, attitude toward the value of medical care and health insurance, and medical conditions. The detrimental effect of lacking health insurance on subjective health status was present for persons at all income levels and was greater than the effect on subjective health status found for 2 of the 11 reported medical conditions. CONCLUSIONS: Lacking health insurance is associated with clinically significant lower levels of subjective health status in both poor and non-poor persons.

Issues in measuring change in self-perceived oral health status.

An important goal of a health care intervention or system is to improve the health of an individual or a population. The challenge for health services research is to measure and explain this change. However, the issue of how changes in health status should be defined and measured has been given relatively little attention. This paper draws on the rather sparse literature to examine some issues involved in measuring changes in oral health status and illustrates these using data from a longitudinal study of the oral health of older adults. The paper draws a distinction between quantitative and qualitative change and the challenges involved with each. Four different ways of assessing change are reviewed and their strengths and weaknesses highlighted. Global transition judgements, although relatively simple measures of change, incorporate patients' values and avoid the statistical problems associated with measures such as change scores. Nevertheless, the measurement of change in oral health status is complex and controversial and no approach is universally accepted. Consequently, the decision as to which strategy to adopt is far from simple.

[Health status in patients with chronic obstructive pulmonary disease].

Health status is usually impaired in patients with moderate to severe chronic obstructive pulmonary disease. Generic and specific questionnaires have been used as measures of the health status. They can provide information on the patient's status that cannot be established using physiological evaluations. Health status is improved by smoking cessation, bronchodilators and rehabilitation. Inhaled corticosteroids can be useful in patients with more severe disease or more frequent exacerbations. No progress in health status has been observed with oral corticosteroids nor mucomodifiers. For patients with severe chronic respiratory failure, health status can sometimes be improved with long-term oxygenotherapy and supplemental oxygenotherapy during exercise.

Year 2000 health status indicators: a profile of California.

OBJECTIVES: To examine the health status of Californians using a set of 18 health status indicators (HSIs) corresponding to goals set forth in Healthy People 2000 and to develop a health status profile for use in research and surveillance, policy development program planning, and program evaluation. METHODS: Federal, state, and county data were used to evaluate California's performance on 18 indicators of health status related to mortality, disease incidence, and health risks. RESULTS: By 1994, California had achieved Year 2000 objectives associated with seven HSIs and significant declines in mortality associated with two other HSIs. Nationally, California was ranked among the states with the lowest rates for infant mortality, lung cancer, female breast cancer, and syphilis but among states with the highest rates for homicide, AIDS, measles, tuberculosis, late prenatal care, childhood poverty, and poor air quality. CONCLUSIONS: California's experience may provide a useful model for other state and local health agencies monitoring the health status of populations using HSIs associated with Year 2000 objectives.

Health behavior and health status: concepts, methods, and applications.

Reviewed current conceptualizations of how health behavior and health status are linked. Although many health providers assume a near perfect relationship between health behavior and health status, empirical verification of this assumption has been difficult. For many diseases, the link between health behavior and health status is weak, nonexistent, or untested. Problems associated with the definition, conceptualization, and measurement of both health behavior and health status are discussed. The impact of treatment effectiveness (i.e., inert, weak, and strong treatments; treatments with linear versus nonlinear health-behavior relationships; and the effect of under- and overtreatment) on health behavior and health status linkages is illustrated.

Measuring health status in chronic airflow limitation.

A health status instrument for use in clinical trials must be valid (measuring what it is supposed to measure) and responsive (able to detect clinically important change). Approaches to measuring health status in clinical trials include using a battery of instruments, a general instrument which provides a profile of the patient's health, an instrument that generates a health utility, or an instrument that focuses on the problems associated with a particular disease. Disease-specific instruments have been used in clinical trials in chronic airflow limitation (CAL). The Oxygen Cost Diagram is simple and easy to administer, but responsiveness and validity are unproven. The Transition Dyspnoea Index is valid and responsive, but is difficult to use in trials in which multiple measurements are desired. The Chronic Respiratory Disease Questionnaire has proved valid and responsive in controlled trials in CAL patients. Health status measures should be included in all clinical trials in CAL.

Health status by gastrointestinal diagnosis and abuse history.

BACKGROUND & AIMS: Standardized assessment of health status by diagnosis (functional vs. organic) and the relative influence of abuse history on health status have not been studied previously. The aim of this study was to estimate the health status and abuse history for gastrointestinal diagnoses among patients seen in a tertiary-care gastroenterology clinic and to evaluate the relative predictive effects of diagnosis and abuse history on health status. METHODS: Standardized measures of sexual and physical abuse history and six health status measures were estimated for the patients by diagnosis. Analysis of covariance was performed to determine the relative contributions of diagnosis type and abuse history on the health status measures. RESULTS: Patients with functional gastrointestinal diagnoses had poorer health status and a higher frequency of severe types of abuse than patients with structural diagnoses. Independent of abuse history, functional diagnosis was significantly associated with greater pain severity and psychological distress and poorer daily function. Independent of diagnosis, abuse history significantly contributed to greater pain severity, more days in bed, more psychological distress, and poorer daily function. CONCLUSIONS: The type of diagnosis and abuse history independently contributed to the health status of this population. Therefore, medical symptoms alone may not be sufficient to understand patients' health status. Attention must also be paid to contributing psychosocial factors.

Weighted health status in the Medicare population: development of the Weighted Health Index for the Medicare Current Beneficiary Survey (WHIMCBS).

We present an approach to constructing an aggregate index of health at the population level with data from Medicare beneficiaries using the 1991 (N = 12,667), 1995 (N = 15,590), and 1997 (N=17,058) Medicare Current Beneficiary Survey (MCBS). Similar to other work with survey data, we develop a weighted health status index from which one can calculate a point in time health status score for any beneficiary. Scores range from 1.0, representing "excellent health and no activity limitation", to 0.0, representing deceased. Sequences of numerically weighted health states experienced over time can be summed to calculate years of healthy life for beneficiaries. We test both the stability of the scoring system when developed on independent samples, as well as the sensitivity of years of healthy life calculations to changes in scoring assumptions. Findings suggest that, in addition to mortality, morbidity appears to play a significant role in the years of healthy life accrued by Medicare beneficiaries since entry into the Medicare program. Further, the index scoring system is highly stable when derived on independent samples. Finally, calculations of years of healthy life are robust to changes in scoring assumptions. The weighted health index for Medicare current beneficiaries (WHIMCBS) is a stable overall index of health and may be a useful ongoing indicator of health within the Medicare population.

Health status of the rural elderly according to farm work history: the Iowa 65 + rural health study.

In a geographically defined survey of 3,097 rural Iowans who were at least 65 yr of age, we examined the association between prior farm experience (greater than or equal to 25 yr) and various measures of current health status; we controlled for age, current working status, and, where appropriate, smoking and alcohol consumption. Health status was indexed by self-reported morbid conditions, symptoms, and physical function. After controlling for smoking behavior, it was found that both men and women with previous farm exposure currently experience a greater prevalence of all nine respiratory symptoms employed in the study relative to non-farmers. Farm men report a lower prevalence of Parkinson's disease and prostate conditions, but report a greater prevalence of stroke and a lower level of self-perceived health status. Women with a farm work history experience a greater level of physical function and fewer symptoms associated with mental illness. Overall significant benefits as well as risks associated with a history of farm work were identified. However, of those who survived to age 65, extended exposure to farm work did not have a major impact on the overall current health status of men and women.
