ASHP survey of ambulatory care responsibilities of pharmacists in managed care and integrated health systems--2001.

The results of a 2001 national survey of the ambulatory care responsibilities of pharmacists in managed care organizations (MCOs) and integrated health systems are reported and compared with the results of similar surveys conducted in 1997 and 1999. Three hundred and seventy-six MCOs and integrated health systems participated in the telephone survey. The surveyelicited data about organizational structure and pharmacist functions in the ambulatory care environment. Survey respondents were asked about 24 specific ambulatory care pharmacist functions. The performance of functions was related to five "enabling" factors: pharmacists on interdisciplinary care teams, automated dispensing systems, integrated electronic medical records, very supportive medical staff, and very supportive senior management. Twenty previously measured functions decreased since 1999. Decreases were greatest in negotiating pharmaceutical contracts (-28%), administering immunizations (-27%), and immunization screening (-24%). Enabling factors supported continued expansion. Two clusters of functions, patient-related and population-related activities, were identified and supported differentially by enabling factors. Group-model and staff-model HMOs had the most enabling factors and the broadest scope of pharmacist functions. Independent practice associations had fewer enabling factors and a different mix of functions, with an emphasis on population-focused functions. Ambulatory care functions of pharmacists have expanded to new areas and have decreased in more traditional areas, perhaps because of the current pharmacist shortage and the increase in the number of prescriptions and patients.

ASHP survey of ambulatory care responsibilities of pharmacists in managed care and integrated health systems--1999.

The results of a 1999 national survey of the ambulatory care responsibilities of pharmacists in managed care organizations (MCOs) and integrated health systems are reported and compared with the results of a similar survey conducted in 1997. Four hundred MCOs and integrated health systems participated in the telephone survey. The survey elicited data about organizational structure and pharmacist functions in the ambulatory care environment. Survey recipients were asked about 24 specific ambulatory pharmacist functions. The performance of functions was related to five "enabling" factors: pharmacists on interdisciplinary teams, automated dispensing systems, integrated electronic medical records, and "very supportive" medical staff and senior management. Thirteen functions were reported to be routine activities for more than 50% of the respondents, compared with nine functions in 1997. The top four functions-using pharmacoeconomic data to make formulary decisions, conducting medication management programs, tracking adverse drug reactions, and providing written information with each new prescription-were performed in 75% or more of organizations. Some 15-18% of respondents indicated they would add specialized pharmacy-managed clinics, services to determine patient use of herbal products and dietary supplements, and Internet prescription services within 12 months, suggesting this expansion is likely to continue. Enabling factors supported expansion. Two clusters of functions were identified that related to either population-focused or patient-focused activities, and these were supported differentially by enabling factors. Group-model and staff-model HMOs had the most enabling factors and the greatest scope of pharmacist functions. Independent practice associations had fewer enabling factors and a different mix of pharmacist functions, with an emphasis on population-focused functions, suggesting that a second model of ambulatory care pharmacist activity may be emerging. Ambulatory care functions of pharmacists in integrated health-system settings have expanded broadly since 1997.

Effect of satisfaction with one's abilities on positive and negative affect among individuals with recently diagnosed rheumatoid arthritis.

OBJECTIVE: The purpose of this study was to examine the effect that self-evaluation processes have on psychologic well-being among individuals with rheumatoid arthritis (RA). METHODS: The study used a longitudinal research design with 4 data collection points. Participants were 227 adults with recently diagnosed RA. Data were collected via mailed questionnaire and telephone interview. Two dimensions of psychologic well-being were assessed--positive affect and negative affect. RESULTS: We found that, among participants who viewed the abilities being evaluated as very important, greater satisfaction at time 1 was associated with less negative affect at time 2 and time 4. Satisfaction was not associated with positive affect at any of the time points, however. CONCLUSION: Study findings indicate that dissatisfaction with illness-related abilities can exacerbate psychologic distress. The findings also highlight the need for research examining the role that positive affect plays in adaptation to RA.

Correlates of changes in mood following a mood induction in osteoarthritis patients.

OBJECTIVE: To determine the relationship of mood management skills, and affective and cognitive states to changes in moods following mood induction among people with osteoarthritis. METHODS: After completing questionnaires, participants underwent a negative mood induction. Momentary moods were assessed prior to, immediately following, and several minutes after the mood induction. RESULTS: A specific mood management skill, mood clarity, consistently predicted changes in positive mood following the mood induction: people who scored high on mood clarity experienced less diminution in positive affect. In contrast, changes in negative affect were unrelated to mood management skills. However, people who scored higher on measures of depressive symptoms and pessimism rebounded from the negative induced mood less strongly than others. CONCLUSION: Positive and negative emotional states operate largely independently and are differentially influenced by mood clarity, depressive symptoms, and pessimism. High levels of mood clarity may be adaptive in illnesses such as osteoarthritis because negative affective experiences that may be unavoidable need not preclude positive affective states.

Using a short food frequency questionnaire to estimate dietary calcium consumption: a tool for patient education.

OBJECTIVE: To develop a short food frequency questionnaire (FFQ) assessing calcium intake and a prediction equation for estimating total calcium intake from the short FFQ. METHODS: Data were collected from 536 women via mailed questionnaires at 3 time points. Stepwise regression analyses were used to identify those foods and beverages included in the Black Health Habits and History Questionnaire (HHHQ) that explained the most variance in participants' dietary calcium intake. A prediction equation was developed to estimate total calcium intake based only on information from the foods/beverages identified. RESULTS: Calcium obtained from 15 foods/beverages explained 97.2% of the variance in total calcium intake. The mean absolute difference between total calcium intake estimated from the 15 foods/beverages and the full HHHQ was less than 50 mg at each time point. CONCLUSION: Findings suggest that a short FFQ can provide estimates of total dietary calcium consumption comparable to the full Block HHHQ.

Health salience: reclaiming a concept from the lost and found.

This paper describes development of a new measure to assess one dimension of health motivation, the salience of health concerns. The new, five-item, measure was administered to 578 women as part of a larger investigation examining the determinants of exercise and calcium consumption. The study used a cross-sectional survey research design. Data were analyzed separately for premenopausal and menopausal women, allowing us to cross-validate our findings in two independent samples. Our findings suggest that the new measure has many desirable psychometric properties. It is internally consistent (Cronbach's alpha = 0.85 and 0.86 for premenopausal and menopausal women, respectively). For both samples, factor analysis revealed that over 60% of the total item variance was explained by a single underlying factor. All factor loadings exceeded 0.74. The measure also correlated in predictable ways with measures of other health beliefs, differentiated among women in different stages of change with respect to exercise and calcium consumption, and discriminated between women on the basis of their information-seeking behavior. We discuss the potential applications of this new measure in future research. Hopefully, the measure will facilitate research on the role that health salience plays in the behavior change process.

Do people with rheumatoid arthritis develop illness-related schemas?

OBJECTIVE: To assess, using both qualitative/inductive and quantitative data, whether people with rheumatoid arthritis (RA) have schemas related to arthritis. METHODS: Themes identified from interview and focus group transcripts were used to develop 1) questionnaire items, and 2) statements participants were asked to recall during home interviews. Two hundred one people with RA completed questionnaires and recall tasks of the type used in cognitive research, followed 10 days later by another recall assessment by telephone. RESULTS: Qualitative methods, item-level questionnaire data, and category-level recall data yielded convergent results supporting 4 final categories: mastery, support, loss of independence, and depression. Regression analyses indicated that category of earlier recollections predicted subsequent recollections assessed via phone. CONCLUSIONS: Results from widely different methods offer at least partial support for arthritis schemas and suggest that the concepts identified are meaningful to patients as well as to researchers.

Behavioral and social research in rheumatology.

The recent literature on behavioral and social research in rheumatology covers the descriptive epidemiology of the behavioral, psychologic, and social impact of rheumatic diseases, the identification of risk factors and predictors of psychosocial outcomes, and cognitive and behavioral interventions used in the management of rheumatic disease. Past studies focused primarily on behavioral and social outcomes in rheumatoid arthritis and osteoarthritis. Recent work has continued to explore these issues in rheumatoid arthritis and osteoarthritis, but a number of studies are examining psychosocial impact and interventions in other rheumatic conditions, such as fibromyalgia and systemic sclerosis. The continued understanding of these consequences of rheumatic disease will enhance the quality of life in individuals who have these conditions.

Osteoporosis prevention in premenopausal women: using a stage model approach to examine the predictors of behavior.

The precaution adoption process model was used to examine the predictors of 2 behaviors recommended to reduce the risk of developing osteoporosis: calcium consumption and weight-bearing exercise. A total of 452 premenopausal women completed a mailed questionnaire assessing stage in the precaution adoption process and 12 knowledge and attitudinal variables. Participants were also given an opportunity to request information about osteoporosis. In all, 11 of the 12 knowledge and attitudinal variables were associated with calcium stage; 8 were associated with exercise stage. Information requests were associated with both calcium and exercise stage. Findings provide substantial support for the precaution adoption process model and suggest that the model can be usefully applied in this area to increase understanding of why many women do not practice behaviors that could reduce their risk of developing osteoporosis.

Arthritis and perceptions of quality of life: an examination of positive and negative affect in rheumatoid arthritis patients.

The utility of measuring both positive and negative affective states for assessing rheumatoid arthritis (RA) patients was examined in 3 independent samples of male and female RA patients (Sample A: 179 women, 48 men; Sample B: 177 women, 24 men; Sample C: 134 women, 38 men). Confirmatory factor analyses of each sample indicated that positive and negative affect constituted separate, negatively correlated factors. The relations among disease variables, coping, and affects were consistent with a model in which coping mediates the relationship between disease variables and positive and negative affect. Patients with higher pain and limitation from RA had higher levels of maladaptive coping, and maladaptive coping was associated with lower positive affect and higher negative affect. Those RAs with higher activity limitation also reported less adaptive coping, which was associated with less positive affect.

Appraisal of and coping with arthritis-related problems in household activities, leisure activities, and pain management.

PURPOSE: We examined whether or not there are systematic differences in how people appraise different types of illness-related problems and in how they cope with these problems. METHODS: Two hundred thirty-five adults with recently diagnosed rheumatoid arthritis completed a mailed questionnaire followed by a telephone interview. A series of stress appraisal and coping variables were assessed in relation to three areas: household activities, leisure activities, and pain management. RESULTS: Pain differed significantly from household and leisure activities with regard to several appraisal and coping variables. Participants reported the least control over problems with pain, while attaching the most importance to pain control. Leisure activities also stood out as unique on several variables. Participants perceived greater ability and were more satisfied with their ability in relation to leisure activities. CONCLUSION: These findings show that, at least early in the disease, appraisal and coping strategies differ across the areas of household activities, leisure activities, and pain management.

Measuring health status among survivors of burn injury: revisions of the Burn Specific Health Scale.

This study examined the reliability of a revised version of the Burn Specific Health Scale (BSHS). Two hundred fifty-four former patients recruited from eight burn centers in the southeastern United States participated in the study. Data were collected via chart review and mailed questionnaire. Factor analyses were used to identify seven subscales containing a total of 31 items. Subsequent analyses provided strong support for the reliability and validity of the revised measure. Each subscale exhibited a high level of reliability (Cronbach's alpha ranged from 0.82 to 0.94). Each subscale also correlated in a predictable manner with measures used for validation. The revised measure should improve the ability of both researchers and clinicians to assess the impact of non-fatal burn injury accurately and comprehensively.

Psychological and educational interventions to reduce arthritis disability.

The extent of disability attributable to arthritis is briefly summarized and the World Health Organization's (WHO) classification scheme for progression from pathology to disability described. The types of outcomes that have been examined in evaluations of psychological and educational interventions aimed at preventing arthritis disability are described and classified according to the WHO scheme where appropriate. Next, the most common components included in psychological and educational interventions for arthritis are reviewed. These are (1) providing general information, (2) teaching illness self-management skills, (3) training in biofeedback, (4) applying cognitive-behavioural techniques, (5) using other psychotherapeutic techniques, and (6) enhancing social support. This is followed by a discussion of issues pertinent to assessing the efficacy of various intervention components, citing specific examples of intervention research. Finally, the conclusion that certain types of psychological interventions appear to be effective in mitigating arthritis disability is drawn and the contribution of social science theory to intervention efficacy acknowledged.

Coping with rheumatoid arthritis: is one problem the same as another?

This study examined how individuals with rheumatoid arthritis (RA) cope with illness-related problems in four different areas: daily activities, leisure activities, work, and social relationships. Eighty-five people with RA took part in the study. They participated in an in-depth interview that focused on the types of changes they had experienced in their lives as a result of their arthritis and how they had coped with these changes. Audiotapes of the interviews were transcribed and content analyzed to assess participants' coping behavior. In addition, standardized measures of psychological and physical functioning were administered shortly following the original interview and at a 4-month follow-up. Three major findings emerged. First, people relied less heavily on behavioral coping strategies when dealing with problems involving social relationships than when dealing with problems involving daily activities, leisure activities, or work. Second, there was little consistency in individuals' use of either cognitive or behavioral strategies across different problem areas. Finally, individuals who exhibited limited flexibility in their coping responses experienced poorer psychological functioning compared with more flexible copers. Implications of these findings for health education practice and future research on coping with RA are discussed.

Psychological well-being among people with recently diagnosed rheumatoid arthritis. Do self-perceptions of abilities make a difference?

OBJECTIVE: Satisfaction with abilities and perceived importance of abilities are 2 factors involved in the process of self-evaluation. We examined the role that these factors play in adjustment to rheumatoid arthritis (RA). METHODS: Data were collected, via telephone interview and mailed questionnaire, from 234 individuals with recently diagnosed RA. Disease severity information was obtained from participants' physicians. RESULTS: Consistent with study hypotheses, satisfaction was associated with psychological well-being only among those who viewed as very important the abilities being evaluated. CONCLUSION: These findings increase understanding of the conditions under which low levels of satisfaction are likely to be associated with psychological distress.
