Psychiatry and general health care.

The paper presents a study of psychiatric morbidity in the general health care program of a Health Maintenance Organization. Mental health services are built into the program as an integral component of primary care teams in internal medicine and pediatrics. The following were some of the findings: 15.7% of patients visiting the Health Center over a two-year period presented emotional problems; 72% were treated by primary care clinicians alone and 28% by mental health clinicians. Treatment by primary and mental health clinicians is broken down by diagnostic categories. A study of patients with chronic emotional problems revealed that they tended to be high utilizers of all Health Center services for both physical and emotional difficulties. Chronic patients represented 2% of all patients who visited in 1974; of these, 54% were seen by mental health clinicians and 46% by primary care clinicians. In the case of patients with non-chronic emotional problems, over a two-year period, there was an increase in the per cent seen by primary clinicians. The use of psychoactive drugs by primary physicians and the advantages and difficulties of developing a program of integrated health-mental services are described.

The mental health of children in an HMO program.

Collaboration between pediatricians and mental health clinicians in an HMO has provided a useful method of identifying and caring for the usual spectrum of developmental and situational disturbances in children and the associated parent-child conflicts. A social worker is included in the primary-care team in pediatrics; other mental health resources are available when indicated. In 1974, 5.7% of total visits and 8.9% of all children under 19 years of age were noted to have emotional problems. A follow-up study carried out early in 1976 disclosed that most of the observed emotional problems were resolved or quiescent.

Integrating mental health services into primary medical care.

Primary care clinicians occupy a strategic position in relation to the emotional problems of their patients. Integrating mental health and primary medical services promotes available, coordinated, accessible, and less stigmatizing treatment by recognizing an indivisibility of the total person in illness and in health. Federal efforts to encourage Health Maintenance Organization (HMO) development as part of a national health program prompts serious attention to organizational arrangements for developing such an integrated program for medical-mental health care. We have found a team collaborative model in which mental health providers are members of a primary care team to be useful and promising. Supportive services are provided on a continuing basis through patterned relationships. Shared responsibility for patient care between physicians, nurse practitioners, physician assistants, and mental health workers provides built-in peer review and encourages intrateam consultation.

Constructing social metrics for health status indexes.

Health status indexes used to make collective decisions satisfying the principles of equality and social minimum must incorporate a social metric for health. Any index or indicator applied to populations for determining health status or to health programs for evaluating outcome must confront the question of who prefers which states of health under which circumstances? Utility models, psychometric scaling, and empirical social decision valuation have been used to measure preferences for states of health. Efforts should be directed toward constructing social metrics for health that are prospective, context-independent, relevant, community-wide, ratio scalled, sensitive, empirically validated, and applicable to program evaluation. These efforts represent the application of normative social theory to research, an important advance in uncovering the mysteries of social action and its consequences.

Quality of life following intensive care.

Evaluations of intensive care have largely focused on survival, cost, or functional status; however, these may not be the only outcomes of interest to patients, families, and health care providers. Quality of life is an important consideration in evaluating intensive care because it influences decisions about the use of life-sustaining treatment. A study was conducted to assess the quality of life of survivors of intensive care to determine the relationship of perceived quality of life to other outcomes of intensive care. Patients at least 55 years old who received medical intensive care during 1983 (n = 69) were interviewed to determine social characteristics, functional status, psychological well-being, and their perceived quality of life using a new 11-item Perceived Quality of Life scale. Functional status correlated only moderately with perceived quality of life (r = 0.49, p = 0.0001). Objective measures of patients' material and social resources did not predict satisfaction. To evaluate outcome adequately, it is necessary to assess perceptions of life quality from patients who have received life-sustaining treatment.

Evaluating quality-of-life and health status instruments: development of scientific review criteria.

The Medical Outcomes Trust is a depository and distributor of high-quality, standardized, health outcomes measurement instruments to national and international health communities. Every instrument in the Trust library is reviewed by the Scientific Advisory Committee against a rigorous set of eight attributes. These attributes consist of the following: (1) conceptual and measurement model; (2) reliability; (3) validity; (4) responsiveness; (5) interpretability; (6) respondent and administrative burden; (7) alternative forms; and (8) cultural and language adaptations. In addition to a full description of each attribute, we discuss uses of these criteria beyond evaluation of existing instruments and lessons learned in the first few rounds of instrument review against these criteria.

Further development and testing of the migraine-specific quality of life (MSQOL) measure.

OBJECTIVE: To evaluate the longitudinal performance of the migraine-specific quality of life (MSQOL) instrument. METHODS: Psychometric tests evaluated data obtained from 1383 migraineurs who completed the 20-item MSQOL questionnaire during a noncomparative, long-term, observational study of zolmitriptan (Zomig), 5 mg, for the acute treatment of migraine attacks of any intensity. RESULTS: There was a relationship between a history of a high frequency of migraine attacks and low baseline MSQOL scores, indicating a lower quality of life. Principal components analyses confirmed three domains and an overall score. Cronbach alpha coefficients for the overall score (.93) indicated high internal consistency. Responsiveness analysis over 180 days of treatment indicated a significantly greater improvement in MSQOL scores (P <.05) in treatment responders compared with nonresponders. The average effect size (0.25) and Guyatt responsiveness statistic (0.46) for the MSQOL instrument exceeded those for the eight domains of the Medical Outcomes Study Short Form Health Survey (MOS SF-36) (-0.05 to 0.14 and 0.01 to 0.12, respectively). Change from baseline for responders in MSQOL total score was 4.7 to 5.4 compared with 1.1 to 2.7 for nonresponders. CONCLUSIONS: Cumulative evidence for the MSQOL instrument meets established criteria for validity, consistency, and reproducibility and shows moderate responsiveness to treatment. This instrument fulfils the need for an MSQOL measure to be used as an adjuvant measure in the assessment of long-term outcomes of therapy.

The rating form of IBD patient concerns: a new measure of health status.

Health status assessment for persons with chronic illness includes not only symptoms, but also an appraisal of the psychosocial concomitants of illness. In this national study of persons with inflammatory bowel disease (IBD), we standardized a disease-specific 25-item measure of perceived health status: the Rating Form of IBD Patient Concerns (RFIPC). Factor analysis yielded four indices: a) impact of disease (e.g., being a burden, loss of energy, loss of bowel control); b) sexual intimacy; c) complications of disease (e.g., developing cancer, having surgery, dying early); and d) body stigma (e.g., feeling dirty or smelly). A higher level of IBD concerns was associated with greater disease severity, female gender, and lower educational status. When controlling for these factors, as well as disease type and age, we found that concerns about: a) impact of disease was positively associated with poorer perception of health and well-being, greater psychological distress (SCL-90), and poorer daily function (Sickness Impact Profile) (p less than 0.0001); b) sexual intimacy was related to poorer psychologic function (p less than 0.01); and c) complications of disease was related to several measures of poorer daily function (p less than 0.0001 to 0.01). This standardized measure of the worries and concerns of persons with IBD may be used in clinical care and research to evaluate the effects of interventions on IBD patient outcomes.

Measuring preferences for health states worse than death.

Previous research indicates that persons assigning values to ranges of health states consider some states to be worse than death. In a study of decisions regarding life-sustaining treatments, the authors adapted and assessed existing methods for their ability to identify and quantify preferences for health states near to or worse than death in a population of well adults and nursing home residents. The cognitive burdens involved in these decisions were also evaluated. Hypothetical health states based on six attributes of functional status were constructed to describe severe constant pain, dementia, and coma. The methods of rank order, category scaling, time tradeoff, and standard gamble were adapted to quantify states worse than death. Cognitive burden was assessed using completion rates, interviewer assessments, respondents' self-reporting, and investigators' evaluations. For both respondent groups, all methods showed similar degrees of cognitive burden for those able to complete the tasks and were similar in their ability to identify and quantify preferences. The majority of nursing home residents, however, were unable to complete or comprehend the measurement tasks. Most respondents evaluated their current health and severe constant pain as better than death; dementia and coma were more often considered equal to or worse than death. These results indicate that respondents can and do evaluate some health states as worse than death. The authors recommend systematic inclusion of states worse than death to describe a more complete range of preference values and routine assessment of the cognitive burdens of assessment techniques to evaluate methodologies.

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.

A comparison of diabetic foot ulcer patients managed in VHA and non-VHA settings.

OBJECTIVE: To compare patients with diabetes and new onset foot ulcers treated in Veterans Health Administration (VHA) and non-VHA settings. METHODS: The treatment of patients with new onset diabetic foot ulcers was prospectively monitored in three VHA and three non-VHA hospitals and outpatient settings until ulcer healing, amputation, or death. RESULTS: Of the 302 individuals enrolled in this study, 47% were veterans receiving VHA care. There were no significant differences between veterans and nonveterans in baseline wound classification, diabetes severity, or comorbid conditions. Veterans received significantly fewer sharp debridements, total contact casts, and custom inserts than their nonveteran counterparts, and they had significantly more x-rays, local saline irrigations, IV antibiotics, and prescriptions for bed rest. The percentage of amputations was higher in veterans but did not achieve statistical significance. CONCLUSIONS: Many commonly held stereotypes of veteran men were not found. Veterans and nonveterans with foot ulcers were similar in terms of health and foot history, diabetes severity, and comorbid conditions. There was considerable variation in treatment of diabetic foot ulcers between VHA and non-VHA care. Yet this variation did not result in statistically significant differences in ulcer outcomes.

Does workplace health promotion decrease medical claims?

We examined the relationship between workplace health promotion and medical claims in 38 textile plants, considering also the effects of demographic and contextual variables (i.e., average worker age, sex ratio, racial composition, plant product, and access to medical services). Number of claims per worker varied threefold among plants but was independent of plant workforce's sex ratio, racial composition, and access to medical services. Worker age predicted claims; in a linear regression model, age, sex, race, plant product, and access explained 23% of variance in claims. Health promotion was also related to claims, and its inclusion in the model (with interaction terms involving plant product) explained 54% of variance in claims, with the deletion of race, sex, and access from the reduced model. We concluded that effective health promotion must address the contexts of different types of plant product.
