ABSTRACT: BACKGROUND: There is growing evidence that even small and solo primary care practices can successfully transition to full Patient Centered Medical Home (PCMH) status when provided with support, including practice redesign, care managers, and a revised payment plan. Less is known about the quality and efficiency outcomes associated with this transition. OBJECTIVE: Test quality and efficiency outcomes associated with 2-year transition to PCMH status among physicians in intervention versus control practices. DESIGN: Randomized Controlled Trial. PARTICIPANTS: Eighteen intervention practices with 43 physicians and 14 control practices with 24 physicians; all from adult primary care practices. INTERVENTIONS: Modeled on 2008 NCQA PPC®-PCMH™, intervention practices received 18 months of tailored practice redesign support; 2 years of revised payment, including up to $2.50 per member per month (PMPM) for achieving quality targets and up to $2.50 PMPM for PPC-PCMH recognition; and 18 months of embedded care management support. Controls received yearly participation payments. MAIN MEASURES: Eleven clinical quality indicators from the 2009 HEDIS process and health outcomes measures derived from patient claims data; Ten efficiency indicators based on Thomson Reuter efficiency indexes and Emergency Department (ED) Visit Ratios; and a panel of costs of care measures. KEY RESULTS: Compared to control physicians, intervention physicians significantly improved TWO of 11 quality indicators: hypertensive blood pressure control over 2 years (intervention +23 percentage points, control -2 percentage points, p = 0.02) and breast cancer screening over 3 years (intervention +3.5 percentage points, control -0.4 percentage points, p = 0.03). Compared to control physicians, intervention physicians significantly improved ONE of ten efficiency indicators: number of care episodes resulting in ED visits was reduced (intervention -0.7 percentage points, control + 0.5 percentage points, p = 0.002), with 3.8 fewer ED visits per year, saving approximately $1,900 in ED costs per physician, per year. There were no significant cost-savings on any of the pre-specified costs of care measures. CONCLUSIONS: In a randomized trial, we observed that some indicators of quality and efficiency of care in general adult primary care practices transitioning to PCMH status can be significantly, but modestly, improved over 2 years, although most indicators did not improve and there were no cost-savings compared with control practices. For the most part, quality and efficiency of care provided in unsupported control practices remained unchanged or worsened during the trial.

ABSTRACT: BACKGROUND: Transition to a Patient-Centered Medical Home (PCMH) is challenging in primary care, especially for smaller practices. OBJECTIVE: To test the effectiveness of providing external supports, including practice redesign, care management and revised payment, compared to no support in transition to PCMH among solo and small (<2-10 providers) primary care practices over 2 years. DESIGN: Randomized Controlled Trial. PARTICIPANTS: Eighteen supported practices (intervention) and 14 control practices (controls). INTERVENTIONS: Intervention practices received 6 months of intensive, and 12 months of less intensive, practice redesign support; 2 years of revised payment, including cost of National Council for Quality Assurance's (NCQA) Physician Practice Connections(®) ─Patient-Centered Medical Home™ (PPC(®)-PCMH™) submissions; and 18 months of care management support. Controls received yearly participation payments plus cost of PPC(®)-PCMH™. MAIN MEASURES: PPC(®)-PCMH™ at baseline and 18 months, plus intervention at 7 months. KEY RESULTS: At 18 months, 5 % of intervention practices and 79 % of control practices were not recognized by NCQA; 10 % of intervention practices and 7 % of controls achieved PPC(®)-PCMH™ Level 1; 5 % of intervention practices and 0 % of controls achieved PPC(®)-PCMH™ Level 2; and 80 % of intervention practices and 14 % of controls achieved PPC(®)-PCMH™ Level 3. Intervention practices were 27 times more likely to improve PPC(®)-PCMH™ by one level, irrespective of practice size (p < 0.001) 95 % CI (5-157). Among intervention practices, a multilevel ordinal piecewise model of change showed a significant and rapid 7-month effect (p (time7) = 0.01), which was twice as large as the sustained effect over subsequent 12 months (p (time18) = 0.02). Doubly multivariate analysis of variance showed significant differential change by condition across PPC(®)-PCMH™ standards over time (p (time x group) = 0.03). Intervention practices improved eight of nine standards, controls improved three of nine (p (PPC1) = 0.009; p (PPC2) = 0.005; p (PPC3) = 0.007). CONCLUSIONS: Irrespective of size, practices can make rapid and sustained transition to a PCMH when provided external supports, including practice redesign, care management and payment reform. Without such supports, change is slow and limited in scope.

ABSTRACT: This study examines whether the general level and rate of change of fatigue over time is different for those rheumatoid arthritis
(RA) patients with and those without a history of affective disorder (AD). Four hundred fifteen RA patients from a national
panel had yearly telephone interviews to obtain fatigue and distress reports, and a one-time semistructured assessment of
the history of depression and generalized anxiety disorder. Growth-curve analysis was used to capture variations in initial
fatigue levels and changes in fatigue over 7 years for those with and without a history. RA patients with a history of major
AD reported levels of fatigue that were 10% higher than those without a history in the 1st year of the study. Their fatigue
reports remained elevated over 7 years. Further analysis showed that the effects of a history of AD on fatigue are fully mediated
through current distress, although those with a history had a significantly smaller distress-fatigue slope. Thus, a history
of AD leaves RA patients at risk for a 7-year trajectory of fatigue that is consistently higher than that of patients without
a history. The elevation in fatigue reports is, at least in part, a function of enduring levels of distress.

ABSTRACT: Asthma, a leading chronic disease of children, currently affects about 6.2 million (8.5%) children in the United States. Despite advances in asthma research and availability of increasingly effective therapy, many children do not receive appropriate medications to control the disease, have over-reliance on reliever medication, and lack systematic follow-up care. The situation is even worse for poor inner-city and minority children who have significantly worse asthma rates, severity, and outcomes. National Asthma Education and Prevention Program Guidelines recommend a multimodal, chronic care approach.
The authors assessed the effectiveness of practice redesign and computerized provider feedback in improving both practitioner adherence to National Asthma Education and Prevention Program Guidelines (NAEPP), and patient outcomes in 295 poor minority children across four Federally Qualified Health Centers (FQHC).
In a nonrandomized, two-group (intervention versus comparison), two-phase trial, all sites were provided redesign support to provide quarterly well-asthma visits using structured visit forms, community health workers for outreach and follow-up, a Web-based disease registry for tracking and scheduling, and a provider education package. Intervention sites were given an additional Web-based, computerized patient-specific provider feedback system that produced a guideline-driven medication assessment prompt.
Logistic regression results showed that providers at intervention sites were more than twice as likely on average to prescribe guideline-appropriate medications after exposure to our feedback system during the Phase I enrollment period than providers at comparison sites (exp(B) = 2.351, confidence interval [CI] = 1.315-4.204). In Phase II (the post-enrollment visit period), hierarchical linear models (HLMs) and latent growth curves were used to show that asthma control improved significantly by .19 (SE = .05) on average for each of the remaining four visits (about 11% of a standard deviation), and improved even more for patients at intervention sites. These results show that implementation of practice redesign support guided by a pediatric chronic care model can improve provider adherence to treatment guidelines as well as patients' asthma control.
The addition of patient-specific feedback for providers results in quicker adoption of guideline recommendations and potentially greater improvements in asthma control compared to the basic practice redesign support alone.

ABSTRACT: Correlates of selective comparisons by mothers of high-risk infants and individuals with rheumatoid arthritis showed that mothers were especially likely to make downward comparisons. Arthritis patients making downward comparisons were rated by their health care providers as more positively adjusted, independent of actual severity of illness. Implications for support providers are discussed.

ABSTRACT: To assess changes in health status of women with fibromyalgia (FM) over 5 years and determine whether baseline employment status influences health outcomes adjusting for other baseline factors.
Two hundred eighty-seven women with FM were recruited from a national sample of rheumatologists and interviewed by phone at baseline and annually for 4 years. Data were collected on pain, fatigue, Center for Epidemiologic Studies Depression Scale and Modified Health Assessment Questionnaire (M-HAQ) scores, demographic characteristics, and employment status. At the end of the study, 211 participants remained. Data were analyzed using multilevel modeling techniques. Bootstrap methods adjusted for the cluster sampling.
The participants' mean +/- SD age was 47 +/- 11 years, their mean +/- SD education level was 14 +/- 2 years, 90% were white, 50% employed, 64% married, and their median household income was >or=$50,000. Mean +/- SD scores at baseline were 57.2 +/- 24 for pain, 75.4 +/- 22 for fatigue, 22.9 +/- 13 for depression, and 0.73 +/- 0.5 for the M-HAQ. Multilevel modeling indicated that all health status measures declined significantly over time except for pain. Rates of change varied from -1.22 for fatigue to -0.03 for the M-HAQ. Except for pain, patients who were employed at baseline had better health status over time. The employment and time interaction was not significant, indicating that health status changed at the same rate regardless of employment status. Other significant factors were age and income.
Employed women with FM have better health status at baseline and maintain that advantage over time. Employment does not seem to provide a protective health benefit.

ABSTRACT: This study examined the association between history of depression and day-to-day coping with rheumatoid arthritis (RA) pain. The sample was 188 RA-diagnosed participants, 73 of whom were identified by a structured clinical interview as having a history of major depression. None had current major depression. All participated in a 30-day prospective study in which they made end-of-day ratings of their arthritis pain, the strategies for how they coped with their pain, their appraisals of daily pain, and daily mood. Hierarchical linear models evaluated whether individuals with and without depression history differed in their average pain and the other daily measures; and separately, whether they differed in their within-person associations between pain and the daily measures (e.g., the day-to-day contingency between pain and mood). All analyses controlled for current mild depressive symptoms, neuroticism, and age. Previously depressed individuals were indistinguishable from their never depressed peers in their average pain and the other daily measures; however, the previously depressed exhibited significantly stronger associations between pain and several aspects of their daily emotional experience, suggesting more pain-contingent well-being. For individuals with a history of depression, increases in daily pain corresponded with more frequent efforts to cope with their pain by venting their emotions, significantly stronger impairments in mood, and, if they were also presently distressed, reduced perceptions of control over their pain, compared to the never depressed. Patterns suggest that formerly depressed individuals exhibit a hidden vulnerability in how they manage chronic pain. This vulnerability is best revealed by a daily process approach.

ABSTRACT: The structure of the job and the daily experience of work are challenges for workers with rheuma-toid arthritis. Yet little is known about how these two factors interact to put workers with chronic pain at risk for worse pain on a given day. This exploratory 20 workday diary study of 27 workers with rheumatoid arthritis used hierarchical linear modeling to examine how the structure of the job and neuroticism moderate the relationship between daily undesirable work events (daily stressors), and pain reports within a day. On days with more undesirable work events compared to days with fewer events, individuals with jobs associated with job "strain" (high demand/low control) reported greater midday pain, irrespective of neuroticism and negative mood, than workers with other com-binations of demand and control. These findings demonstrate the utility of analyzing fluctuating within-person relationships among pain, mood, and daily work stressors within the context of the structure of the job, and helps to explain why daily work stressors result in worse health outcomes for some but not all workers with RA.

ABSTRACT: To estimate the rate of change in functional limitations for patients with rheumatoid arthritis (RA) as a function of age, duration of illness, and sex.
Patients with RA (n = 700) aged 21-65 years in 1988 were interviewed yearly for 6 years in The National Rheumatoid Arthritis Study. Functional limitations scores based on a Rasch measurement model of 20 Health Assessment Questionnaire items were analyzed in mixed-effects models to estimate the rate of change in functional ability as a function of age, duration of illness, sex, and interactions.
Models for both patient age and duration of illness significantly predicted limitations in functional ability for men and women. The model for age included a significant cubic effect; the model for duration of illness included a significant linear effect only. Sex was significant in both models and no interactions were significant in either model. The AIC index of fit, an indicator of the information value of the model, favored the model for duration of illness over the model for age. While both models showed higher levels of functional limitations in women than men, the rate of change for women was similar to men.
Limitation in functional ability in RA progressed in a linear manner with duration of illness and progressed at the same rate for both men and women, but functional limitations were greater for women.

ABSTRACT: To evaluate how a prior affective disorder (major depression or generalized anxiety disorder) affects current fatigue among individuals with rheumatoid arthritis (RA). To determine whether that relationship is mediated by self-efficacy expectations.
Forty-eight RA patients with a prior affective disorder and 74 without a history of affective disorder completed a mailed questionnaire that included the Multidimensional Assessment of Fatigue and indicators of neuroticism and self efficacy.
RA patients with a history of affective disorder reported higher levels of fatigue than those with no previous affective disturbance. Controlling for neuroticism and self efficacy, affective disorder history continued to predict current fatigue. Mediational analyses revealed both direct and indirect effects (via self efficacy) of history of affective disorder on the experience of fatigue in RA.
History of affective disorder independently predicts higher levels of fatigue in RA patients, and self efficacy plays a mediating role in this relationship.

ABSTRACT: The purpose of this study was to assess the effects of paid employment on health related quality of life among women with fibromyalgia compared to a group of women who were otherwise healthy. Participants were recruited from 118 rheumatology practices randomly sampled from the membership of the American College of Rheumatology. Three hundred and sixty-five patients were referred to the study and 287 completed a telephone interview. At the end of each interview, participants were asked to nominate 2 individuals to serve as control subjects. Because of lagging enrollment of control subjects, we initiated an additional method of asking control subjects to nominate controls. Of 381 control subjects nominated for the study, 286 or 75% completed the initial interview. As with patients, controls completed a computer assisted phone interview with a trained interviewer similar to that of the patient. The mean age of women with FMS was 47 years, most were married (59.6%), 87.8% were of white race and non-Hispanic ethnicity, 47.7% were employed, had an average of 14 years of education and household annual incomes generally exceeded $20,000, with 40.4% having incomes in excess of $50,000. There we no significant differences between women with FMS and those without FMS on these characteristics. Women with FMS had significantly worse physical and mental health related quality of life measured by SF-12 Physical (PCS) and Mental (MCS) Component Summary Scores; those who were not employed had significantly worse PCS scores but there were no differences by employment for MCS. Ordinal regression analysis adjusting for demographic characteristics showed that there were significant main effects for condition and employment on PCS in that those with FMS and those who were not employed had worse PCS scores. Initially, we also found an interaction effect between condition and employment in that the beneficial effects of employment was restricted to the FMS cases. However, when adjustments were made for the double nesting design, the interaction effect was no longer significant. For MCS, FMS cases had significantly worse health related quality of life, but there were no main effects for employment and no interactions were significant. Our results concur with findings in community studies that employed women report better quality of life than those not employed, but only for the physical dimension of quality of life. The findings regarding MCS are intriguing in that women with FMS are not very different from controls and that employment has little effect on the mental health component of quality of life.

ABSTRACT: To assess health status differences of women with fibromyalgia syndrome (FM) who are employed and not employed, and to evaluate whether employment and family work influence the health status of women with FM as it does for women in community studies.
Participants were 287 women recruited from 118 randomly selected rheumatology practices. They completed telephone interviews that collected data on demographic characteristics, health status, symptoms, family work, and social support. One hundred thirty-seven were employed and 150 were not employed. Formal statistical analysis, including estimation and testing, focused on the relationship between employment and 4 health status measures: Modified Health Assessment Questionnaire (MHAQ), visual analog scale (VAS) for pain on the interview day, number of painful areas, and VAS for fatigue on the interview day. The relationship between employment and these measures was evaluated using analysis of variance, chi-square, linear regression, and ordinal logistic regression.
The majority of participants reported high levels of symptoms and poor health status. In the bivariate analyses, employed women reported significantly less pain, less fatigue, and better functional status than those who were not employed. In the multivariate analyses, employment remained a significant factor in explaining number of painful areas, functional status (MHAQ), and fatigue, with employed women reporting better health status than those not employed. Employment was not associated with pain on the day of the interview when other factors were considered in the analysis. The psychological demands of family work were consistently related to all dependent measures of health status, as those with greater psychological demands reported worse health status.
As in community studies, employed women with FM report better health status than women who are not employed. The demands of family work exert a serious and significant effect on every dimension of health status and should be the focus of greater clinical attention. Further followup will assess whether employment has a protective effect for women with FM as in community studies or whether women with less severe FM tend to remain in the workforce.

ABSTRACT: To compare 3 commonly used psychiatric symptom checklists (the Center for Epidemiological Studies Depression Scale [CES-D], the Positive and Negative Affect Schedule, and the Endler Multidimensional Anxiety Scales [EMAS]) to determine their sensitivity, specificity, and ability to discriminate between a disorder (Major Depression [MD], Generalized Anxiety Disorder [GAD]), and no disorder. To compare the checklists for their ability to discriminate between type of disorder (MD and GAD). To evaluate the discriminant ability of the subscales, particularly positive affect; whether the somatic items in the CES-D artificially inflate affective scores; and the optimal cut off score for the CES-D.
We compared the 3 scales to diagnostic criterion of MD, GAD, and comorbid disorder using receiver operator characteristic (ROC) and logistic regression analyses. The sample consisted of a national panel of 415 individuals with rheumatoid arthritis (RA).
Each of the scales had high sensitivity and specificity (areas under the curve: CES-D = 0.92, negative affect = 0.88, positive affect and EMAS = 0.82). The CES-D, however, demonstrated better sensitivity and specificity than the positive affect and the EMAS, but not the negative affect scale.
All 3 self-reports have high combined sensitivity and specificity as measures of affective disorders among RA patients.

ABSTRACT: Claims data are a problematic indicator of underlying clinical diagnosis. They are attractive because of their affordability, a criterion especially salient in resource-shy environments such as the Medicaid Managed Care Organization. This study tested the validity of administrative medical and pharmaceutical claims stratified by treatment modality to identify true pediatric asthma patients. Primary and secondary data were used. Secondary data consisted of 1997 medical and pharmaceutical claims. Primary data consisted of chart data collected through expert chart review. We stratified claims by treatment modality hypothesized to better identify true asthma patients. Claim patterns were analyzed for support of expectations. Expert chart review determined true asthma status on study sample. We found that claims are patterned in accordance with hypotheses about stratification groups. The combined use of both medical and pharmaceutical claims was more effective in identifying asthmatics than the use of either set of claims by itself. The Medicaid Managed Care Organization can begin to identify its asthma population using the stratification meth.

ABSTRACT: Little is known about the role of psychological factors in the functional recovery process of hip fracture patients. This study employed a prospective cohort design to test the hypothesis that hospitalized hip fracture patients with greater reported self-efficacy for conducting rehabilitation therapy would have a greater likelihood of recovering to a pre-fracture level of locomotion function six months after the fracture. This hypothesis was tested controlling for pre-fracture level of function and depressive symptoms reported during hospitalization for surgical repair. An original measure of rehabilitation therapy self-efficacy was evaluated prior to hypothesis testing. Study patients were recruited from two hospitals, interviewed during hospitalization and followed up six months later. Patients included in hypothesis test analyses (n = 24) were mostly women (82%) with a mean age of 79 years. Results showed that patients with higher self-efficacy scores had a greater likelihood of locomotion recovery, controlling for pre-fracture locomotion function level (adjusted odds ratio (AOR) = 1.21; 95% confidence interval (CI) = 1.00-1.45; P= 0.05). This positive association between rehabilitation therapy self-efficacy and likelihood of locomotion recovery persisted after adding depressive symptoms (the Center for Epidemiological Studies-depression (CES-D) score) to this logistic regression model (AOR for self-efficacy = 1.18; 95% CI = 0.99-1.42; P= 0.07). It is concluded that rehabilitation therapy self-efficacy is a potentially important psychological factor in helping hip fracture patients recover locomotion functioning.

ABSTRACT: In a study of 92 patients with rheumatoid arthritis, we examined patients' beliefs about the causes of their illness, disease flares, and disease remissions, and about the selective incidence of the disease. Numerous self-report measures were used to elucidate the patients' attitudes and perceptions; the tendency of patients to present themselves in socially desirable ways was taken into account and was found not to influence the study results. The causes for the illness that were most frequently cited by patients were heredity (34.7%), autoimmune factor (24.4%), personal behaviors (22.8%), and psychological stress (22.8%). Patients who were more actively searching for the causes of the illness and who continued to ask “Why me?” reported greater functional problems and a greater sense of helplessness. The most frequently cited causes for symptom flares were psychological stress (45.5%), changes in weather (34.0%), and excessive physical activity (34.1%). Symptom remissions were most frequently believed to be related to medication changes (49.4%) and the absence of psychological stress (21.0%). Several of these causal beliefs were related to perceptions of helplessness and the illness' predictability and to health care providers' assessments of disease severity and patients' psycho-social adjustment.
