Associations Between Patient Characteristics and the Amount of Arthritis Medication Information Patients Receive.

Little is known about factors associated with the receipt of medication information among arthritis patients. This study explores information source receipt and associations between demographic and clinical/patient characteristics and the amount of arthritis medication information patients receive. Adult patients with osteoarthritis (OA) or rheumatoid arthritis (RA; n = 328) completed an online cross-sectional survey. Patients reported demographic and clinical/patient characteristics and the amount of arthritis medication information received from 15 information sources. Bivariate and multivariate linear regression analyses were used to investigate whether those characteristics were associated with the amount of medication information patients received. Arthritis patients received the most information from health professionals, followed by printed materials, media sources, and interpersonal sources. Greater receipt of information was associated with greater medication adherence, taking more medications, greater medication-taking concerns, more satisfaction with doctor medication-related support, and Black compared to White race. RA patients reported receiving more information compared to OA patients, and differences were found between RA patients and OA patients in characteristics associated with more information receipt. In conclusion, arthritis patients received the most medication information from professional sources, and both positive (e.g., greater satisfaction with doctor support) and negative (e.g., more medication-taking concerns) characteristics were associated with receiving more medication information.

The impact of co-morbidity on health-related quality of life in rheumatoid arthritis and osteoarthritis patients.

OBJECTIVES: We investigated whether comorbidities differentially impacted health-related quality of life (HRQOL) for rheumatoid arthritis (RA) and osteoarthritis (OA) patients. METHODS: Adult patients with self-reported doctor-diagnosed RA (n=159) or OA (n=149) were recruited from multiple sources and completed an online cross-sectional survey. Patients self-reported sociodemographic variables, arthritis severity and comorbid conditions. HRQOL was assessed using the SF-12v2 and comorbidity counts were assigned using an expanded Functional Comorbidities Index. HRQOL (8 domain and 2 composite (physical and mental health) scores) was compared with norm-based general US population scores and between RA and OA patients to determine if they significantly differed from one another. Linear regression was used to test whether comorbidity count was associated with the physical and mental health of RA and OA patients. RESULTS: OA and RA patients experienced significantly worse HRQOL across all dimensions compared with that of the general US population. There were no significant differences between RA and OA patients on any HRQOL dimension. A higher comorbidity count was associated with worse physical (p=0.0007) and mental (p=0.0295) health scores when controlling for patient gender, age, education, and arthritis severity. CONCLUSIONS: Arthritis negatively impacted patients' HRQOL. OA patients in our sample perceived their condition as similarly disabling in terms of physical and mental health as RA patients. Arthritis patients with more chronic comorbid conditions may be at particular risk for poor physical and mental health. Providers should discuss management of comorbid conditions with arthritis patients.

Opt-out HIV testing in prison: informed and voluntary?

HIV testing in prison settings has been identified as an important mechanism to detect cases among high-risk, underserved populations. Several public health organizations recommend that testing across health-care settings, including prisons, be delivered in an opt-out manner. However, implementation of opt-out testing within prisons may pose challenges in delivering testing that is informed and understood to be voluntary. In a large state prison system with a policy of voluntary opt-out HIV testing, we randomly sampled adult prisoners in each of seven intake prisons within two weeks after their opportunity to be HIV tested. We surveyed prisoners' perception of HIV testing as voluntary or mandatory and used multivariable statistical models to identify factors associated with their perception. We also linked survey responses to lab records to determine if prisoners' test status (tested or not) matched their desired and perceived test status. Thirty-eight percent (359/936) perceived testing as voluntary. The perception that testing was mandatory was positively associated with age less than 25 years (adjusted relative risk [aRR]: 1.45, 95% confidence interval [CI]: 1.24, 1.71) and preference that testing be mandatory (aRR: 1.81, 95% CI: 1.41, 2.31) but negatively associated with entry into one of the intake prisons (aRR: 0.41 95% CI: 0.27, 0.63). Eighty-nine percent of prisoners wanted to be tested, 85% were tested according to their wishes, and 82% correctly understood whether or not they were tested. Most prisoners wanted to be HIV tested and were aware that they had been tested, but less than 40% understood testing to be voluntary. Prisoners' understanding of the voluntary nature of testing varied by intake prison and by a few individual-level factors. Testing procedures should ensure that opt-out testing is informed and understood to be voluntary by prisoners and other vulnerable populations.

The role of companionship, esteem, and informational support in explaining physical activity among young women in an online social network intervention.

The primary objective of the current study was to examine the relationship between social support and physical activity within the theory of planned behavior (TPB) theoretical framework. This study used data from the Internet Support for Healthy Associations Promoting Exercise randomized controlled trial. A total of 134 female undergraduate students participated in the study, which included baseline and post measures of perceived social support for physical activity (esteem, informational, and companionship), TPB variables related to physical activity (perceived behavioral control, intention, and attitude), and physical activity behavior. Path analysis revealed a significant indirect relationship between change in companionship support and physical activity mediated by change in intention (.13, p < .01) and a significant direct relationship between change in esteem support and change in physical activity (.26, p = .03). The model explained 27% of the variance in physical activity and 59% of the variance in intention. Overall, change in social support exerted a small to medium amount of influence on change in physical activity in this modified TPB model when controlling for traditional model constructs. Encouraging companionship and esteem support should be considered as a strategy for increasing physical activity in this population.

Conflicting medication information: prevalence, sources, and relationship to medication adherence.

Conflicting medication information has been defined as contradictory information about a medication topic from two or more sources. The objective of this study was to determine whether arthritis patients are exposed to conflicting medication information, to document sources of conflicting information, and to explore whether conflicting information is associated with sociodemographic factors, clinical characteristics, and medication adherence. Using an online survey, arthritis patients (N = 328) reported how often they received conflicting information about 12 medication topics as well as sources of conflicting information, demographic/clinical characteristics, and medication adherence. A linear regression model, which controlled for various demographic/clinical factors, determined whether conflicting information was associated with medication adherence. The majority of patients (80.1%) received conflicting information and were most likely to receive conflicting information about medication risks. Physicians, media sources, and the Internet were the most common sources of conflicting information. Less conflicting information (B =-0.13, p < .05), more information source use (B = 0.22, p < .01), and lower perceived regimen complexity (B =-0.17, p < .05) were associated with better medication adherence. In conclusion, conflicting medication information is pervasive, comes from a variety of sources, and may negatively affect patient health outcomes. To potentially decrease exposure to conflicting information, providers should direct patients to high-quality medication information sources.

Differences in effectiveness of the active living every day program for older adults with arthritis.

OBJECTIVE: The authors explored whether demographic and psychosocial variables predicted differences in physical activity for participants with arthritis in a trial of Active Living Every Day (ALED). METHOD: Participants (N = 280) from 17 community sites were randomized into ALED or usual care. The authors assessed participant demographic characteristics, self-efficacy, outcome expectations, pain, fatigue, and depressive symptoms at baseline and physical activity frequency at 20-wk follow-up. They conducted linear regression with interaction terms (Baseline Characteristic × Randomization Group). RESULTS: Being female (p ≤ .05), less depressed (p ≤ .05), or younger (p ≤ .10) was associated with more frequent posttest physical activity for ALED participants than for those with usual care. Higher education was associated with more physical activity for both ALED and usual-care groups. DISCUSSION: ALED was particularly effective for female, younger, and less depressed participants. Further research should determine whether modifications could produce better outcomes in other subgroups.

The impact of vasculitis on patients' social participation and friendships.

OBJECTIVES: Our objective is to explore how vasculitis affects patients' friendships and social participation. METHODS: Vasculitis patients (n=221) completed an online questionnaire that asked if, and how, relationships with friends have changed since receiving a vasculitis diagnosis. Participants' written responses were imported into Atlas.ti, and two independent researchers used both structured and unstructured coding to identify themes. After reaching 100% consensus on the themes present in each participant's responses, the coders determined how themes were interrelated across participants. RESULTS: Over half of patients (52%) expressed that vasculitis negatively impacted their friendships and 25% noted a negative impact on their social participation. At times, this negative impact was related to structural changes in patients' social networks due to loss of friendships. Reduced social participation was also associated with friends' inability to understand vasculitis and its effects, vasculitis-related fatigue, and lifestyle changes such as not being able to drink alcohol and avoiding infection-prone events. Additionally, patients withdrew from social engagements due to fatigue or because of physical symptoms and side effects. CONCLUSIONS: The unique circumstances associated with a rare chronic illness like vasculitis can create significant barriers to friendships, including loss of these relationships. Interventions designed to help patients cope with the social impact of vasculitis are implicated, especially if they increase patients' ability to engage in dialogue about their illness with their friends.

Does adherence-related support from physicians and partners predict medication adherence for vasculitis patients?

Few studies have explored mediators between medication-related support and medication adherence for individuals with rare, systemic autoimmune conditions. Using the Information-Motivation-Behavioral Skills model, we tested whether depressive symptomatology and medication adherence self-efficacy mediated the relationship between adherence support and changes in medication adherence among vasculitis patients, and whether support from physicians and partners differentially affected medication adherence. Vasculitis patients (n = 172) completed baseline and follow-up questionnaires about their medication adherence and perceived adherence support. Bootstrapped mediation analyses tested the effects of physician and partner support on changes in medication adherence. Adherence self-efficacy mediated the relationship between physician support and changes in medication adherence (B = 0.05, SE = 0.03, 95% CI 0.01, 0.13). Neither self-efficacy nor depressive symptomatology mediated the effects of partner support. Although physicians spend little time with patients, they can increase patients' confidence about taking medications correctly and potentially improve health outcomes by bolstering medication adherence.

Patients with rare diseases using pharmacists for medication information.

OBJECTIVES: To determine whether patients with a rare illness (1) use pharmacists for medication information more or less frequently than physicians and the Internet, (2) perceive pharmacists as a more or less credible medical information resource than physicians and the Internet, and (3) obtain different types of medication information from pharmacists, physicians, and the Internet. DESIGN: Cross-sectional survey. SETTING: Online data collected between 2008 and 2009. PATIENTS: Adult, English-proficient vasculitis patients (n = 232) who were taking at least one medication to treat their vasculitis. INTERVENTION: Administration of online survey. MAIN OUTCOME MEASURES: Patient use of pharmacists, physicians, and the Internet for medication information; perceived credibility of pharmacists, physicians, and the Internet as sources of medication information; and types of medication information obtained from pharmacists, physicians, and the Internet. RESULTS: Participants consulted physicians and the Internet more than pharmacists for medication information; only 96 participants (41.4%) ever used pharmacists for vasculitis medication information. Females and participants who used community pharmacies were significantly more likely to consult pharmacists for medication information as compared with males and patients who did not use community pharmacies. Participants perceived pharmacists were a less credible source of medication information than physicians and the Internet. Participants used physicians and/or the Internet more than pharmacists for five of eight types of medication information, including adverse effects and drug effectiveness. CONCLUSION: Vasculitis patients consulted sources other than pharmacists for medication information. Several factors, including perceived pharmacist credibility and a noncommunity-based pharmacy, may contribute to infrequent patient use of pharmacists as a medication information source. Future qualitative research should document how patients with rare disease perceive and interact with pharmacists to understand why many view pharmacists as only moderately credible sources of medication information.

Use and perceived credibility of medication information sources for patients with a rare illness: differences by gender.

Patients with rare illnesses may use medication information sources that are appreciably different from those used by patients with more common illnesses. This article's purpose is to describe vasculitis patients' most frequently used medication information sources, determine which sources patients perceive as credible, and explore gender differences in source use and perceived credibility. Using an online questionnaire, patients (n = 232) indicated how often they obtained medication information from 12 sources during the previous year and rated the credibility of 6 sources. The authors used multivariate analysis of covariance and follow-up contrasts to test for gender differences in source use and conducted t tests to compare patients' perceived credibility ratings. Patients used physicians and the Internet most often to obtain medication information and rated them as the most credible sources. Male patients used their spouse/partner more often and rated them as more credible than did female patients. Female patients were more likely to use medication package inserts and the Internet and were less likely to use nurses than were male patients. There appear to be similarities and differences between the information-seeking behaviors of vasculitis patients and other patient populations. Because male patients view their spouse/partner as a credible information source, providers may want to involve the spouse/partner in prescription decision making.

Measuring social health in the patient-reported outcomes measurement information system (PROMIS): item bank development and testing.

PURPOSE: To develop a social health measurement framework, to test items in diverse populations and to develop item response theory (IRT) item banks. METHODS: A literature review guided framework development of Social Function and Social Relationships sub-domains. Items were revised based on patient feedback, and Social Function items were field-tested. Analyses included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), two-parameter IRT modeling and evaluation of differential item functioning (DIF). RESULTS: The analytic sample included 956 general population respondents who answered 56 Ability to Participate and 56 Satisfaction with Participation items. EFA and CFA identified three Ability to Participate sub-domains. However, because of positive and negative wording, and content redundancy, many items did not fit the IRT model, so item banks do not yet exist. EFA, CFA and IRT identified two preliminary Satisfaction item banks. One item exhibited trivial age DIF. CONCLUSION: After extensive item preparation and review, EFA-, CFA- and IRT-guided item banks help provide increased measurement precision and flexibility. Two Satisfaction short forms are available for use in research and clinical practice. This initial validation study resulted in revised item pools that are currently undergoing testing in new clinical samples and populations.

Use of complementary and alternative medicine among patients with arthritis.

INTRODUCTION: Previous studies suggest that people with arthritis have high rates of using complementary and alternative medicine (CAM) approaches for managing their arthritis, in addition to conventional treatments such as prescription medications. However, little is known about the use of CAM by diagnosis, or which forms of CAM are most frequently used by people with arthritis. This study was designed to provide detailed information about use of CAM for symptoms associated with arthritis in patients followed in primary care and specialty clinics in North Carolina. METHODS: Using a cross-sectional design, we drew our sample from primary care (n = 1,077) and specialist (n = 1,063) physician offices. Summary statistics were used to calculate differences within and between diagnostic groups, practice settings, and other characteristics. Logistic regression models clustered at the site level were used to determine the effect of patient characteristics on ever and current use of 9 CAM categories and an overall category of "any use." RESULTS: Most of the participants followed by specialists (90.5%) and a slightly smaller percentage of those in the primary care sample (82.8%) had tried at least 1 complementary therapy for arthritis symptoms. Participants with fibromyalgia used complementary therapies more often than those with rheumatoid arthritis, osteoarthritis, or chronic joint symptoms. More than 50% of patients in both samples used over-the-counter topical pain relievers, more than 25% used meditation or drew on religious or spiritual beliefs, and more than 19% used a chiropractor. Women and participants with higher levels of education were more likely to report current use of alternative therapies. CONCLUSION: Most arthritis patients in both primary care and specialty settings have used CAM for their arthritis symptoms. Health care providers (especially musculoskeletal specialists) should discuss these therapies with all arthritis patients.

Effect of couple illness perception congruence on psychological adjustment in women with rheumatoid arthritis.

OBJECTIVE: To characterize similarities and differences in illness perceptions between women with rheumatoid arthritis (RA) and their husbands, and examine whether illness perception congruence predicted wives' subsequent psychological adjustment. DESIGN: Women with RA and their husbands (N=190 couples) recruited from community and clinical settings completed mailed surveys at baseline and 4-month follow-up. MAIN OUTCOME MEASURES: Data for this investigation included illness perceptions in partners and illness severity, marital variables, and psychological adjustment in wives. RESULTS: In general, wives and husbands had similar views of RA. Couple congruence concerning women's personal control over RA and its cyclic nature predicted better psychological adjustment in women 4 months later. Post hoc tests showed better psychological adjustment in wives from couples with similar optimistic beliefs about personal control, illness coherence, and RA consequences, when compared to those in couples with similar pessimistic beliefs. Furthermore, when partners disagreed about RA's consequences, wives fared better when husbands overestimated rather than underestimated their beliefs. In contrast, couple congruence about the emotions and timeline of RA was unrelated to adjustment. CONCLUSION: It may be important for husbands to understand wives' views on their control over RA and its cyclic nature. Furthermore, wives may benefit when they share optimistic views with their husbands about RA, and when their husbands avoid underestimating RA's consequences. Developing interventions to enhance partners' illness understanding may be beneficial.

Disparities in pain management between cognitively intact and cognitively impaired nursing home residents.

This study tests the association between residents' cognitive impairment and nursing homes' pain management practices. We used chart abstraction to collect data on 551 adults in six North Carolina nursing homes. From the standard data collected in the Minimum Data Set, 24% of residents experienced pain in the preceding week. Reports of pain decreased as cognitive abilities declined: nurses completing the Minimum Data Set reported pain prevalence of 34%, 31%, 24%, and 10%, respectively, for residents with no, mild, moderate, and severe cognitive impairment (P<0.001), demonstrating a "dose-response"-type result. Eighty percent of cognitively intact residents received pain medications, compared to 56% of residents with severe impairment (P<0.001). Cognitively impaired residents had fewer orders for scheduled pain medications than did their less cognitively impaired peers. Yet the presence of diagnoses likely to cause pain did not vary based on residents' cognitive status. We conclude that pain is underrecognized in nursing home residents with cognitive impairment and that cognitively impaired residents often have orders for "as needed" analgesics when scheduled medications would be more appropriate.

Views of treatment decision making from adolescents with chronic illnesses and their parents: a pilot study.

OBJECTIVE: Shared decision making may increase satisfaction with health care and improve outcomes, but little is known about adolescents' decision-making preferences. The primary purpose of this study is to describe the decision-making preferences of adolescents with chronic illnesses and their parents, and the extent to which they agree. DESIGN: Survey. SETTING AND PARTICIPANTS: Participants were 82 adolescents seen at one of four paediatric chronic illness subspecialty clinics and 62 of their parents. MAIN VARIABLES: Predictor variables include sociodemographics, health parameters, risk behaviour, and physical and cognitive development. The main outcome variable is preferences for decision-making style. RESULTS AND CONCLUSIONS: When collapsed into three response categories, nearly equal percentages of adolescents (37%) and parents (36%) preferred shared decision making. Overall, the largest proportion of adolescents (46%) and parents (53%) preferred passive decision making compared to active or shared decision making. Across five response choices, 33% of pairs agreed. Agreement was slight and not significant. Improved general health perceptions (OR=0.76, 95% CI=0.59-0.99) and improved behaviour (OR=0.75, 95% CI=0.56-0.99) were significantly associated with parents' preferences for less active decision making. Older age was significantly associated with agreement (OR 1.58, 95% CI=1.09-2.30) between parents and adolescents. The paucity of significant predictor variables may indicate physicians need to inquire directly about patient and parent preferences.

Older adults in the rural South are not meeting healthful eating guidelines.

OBJECTIVE: To evaluate diet quality of rural older adults using national dietary guidelines and the Healthy Eating Index (HEI). DESIGN: Five to six 24-hour recalls were conducted at monthly intervals over a 6-month period, using the Nutrition Coordinating Center food grouping system to calculate intake. SUBJECTS: Included in this cross-sectional study were 63 females and 59 males aged 65 to 93 years residing in two rural North Carolina counties; one third of each sex group was African American, Native American, or white. Inclusion criteria included age>65 years, education

Healthy coping, negative emotions, and diabetes management: a systematic review and appraisal.

PURPOSE: The purpose of this systematic review is to assess the literature pertinent to healthy coping in diabetes management and to identify effective or promising interventions and areas needing further investigation. METHODS: A PubMed search identified 186 articles in English published between January 1, 1990, and July 31, 2006, addressing diabetes and emotion, quality of life, depression, adjustment, anxiety, coping, family therapy, behavior therapy, psychotherapy, problem solving, couples therapy, or marital therapy. RESULTS: Connections among psychological variables, behavioral factors, coping, metabolic control, and quality of life are appreciable and multidirectional. Interventions for which well-controlled studies indicate benefits for quality of life and/or metabolic control include general self-management, coping/problem-solving interventions, stress management, support groups, cognitive-behavioral therapy, behavioral family systems therapy, cognitive-analytic therapy, multisystemic therapy, medications for depression, and the Pathways intervention integrating case management, support of medication, and problem-solving counseling. CONCLUSIONS: Psychological, emotional, related behavioral factors, and quality of life are important in diabetes management, are worthy of attention in their own right, and influence metabolic control. A range of interventions that achieve benefits in these areas provide a base for developing versatile programs to promote healthy coping.

Examining whether the information-motivation-behavioral skills model predicts medication adherence for patients with a rare disease.

The information-motivation-behavioral skills (IMB) model has been used to explain and promote medication adherence among patients with diabetes and HIV. The objective of this study was to examine whether the IMB model predicted medication adherence among vasculitis patients. Adult vasculitis patients (n=228) completed online questionnaires at baseline and 3-month follow-up. Linear regressions were calculated to determine the direct effects of information and motivation on medication adherence (P<0.05). A mediation analysis using a bootstrapping approach was used to test whether behavioral skills significantly mediated the effect of information and motivation on medication adherence. Participants reported high levels of information (M=4.0; standard deviation [SD]=0.68), moderate levels of motivation (M=2.7; SD=1.00), and high levels of behavioral skills (M=4.1; SD=0.74). In the regression model, only behavioral skills (B=0.38; P<0.001) were significantly associated with medication adherence; however, mediation analysis revealed that behavioral skills significantly mediated the effects of information and motivation on medication adherence. The results support the IMB-hypothesized relationships between information, motivation, behavioral skills, and medication adherence in our sample. Findings suggest that providers should work with vasculitis patients to increase their medication-related skills to improve medication adherence.

Four methods of estimating the minimal important difference score were compared to establish a clinically significant change in Headache Impact Test.

OBJECTIVE: To estimate the smallest decrease in Headache Impact Test (HIT) scores that reflects meaningful clinical change among patients with chronic daily headache (CDH). STUDY DESIGN AND SETTING: We applied four methods of estimating the minimum important difference (MID) to data from 71 patients with CDH who participated in a clinical trial. The HIT was administered at baseline and at the 6-week follow-up assessment. Patients were considered to have experienced meaningful improvement if they reported that their headache condition was "somewhat better" or "much better" at the 6-week follow-up. RESULTS: Mean HIT scores at baseline and 6 weeks for all patients were 64.5 (standard deviation SD = 6.0) and 62.6 (SD = 5.7), respectively. HIT scores decreased 3.7 (SD = 4.4) and 1.4 (SD = 3.6) units, respectively, among patients who reported "somewhat better" change and those who reported no change at 6 weeks. Estimates of the MID of the HIT ranged from -2.7 to -2.3. CONCLUSIONS: The method that we judge to be most valid estimated the MID of the HIT at -2.3 units (95% confidence interval = -4.3, -0.3). This suggests that a between-group difference in HIT change scores of 2.3 units over time among patients with CDH reflects improvement in patients' headache condition that may be considered clinically significant.

Identifying supports and barriers to physical activity in patients at risk for diabetes.

INTRODUCTION: Recent clinical trials have demonstrated that increasing physical activity among patients at risk for diabetes can prevent or delay the onset of type 2 diabetes. In this study, we surveyed primary care patients at risk for diabetes to 1) describe physical activity habits, supports, and barriers; 2) identify characteristics associated with increased physical activity; and 3) develop and assess the psychometric properties of an instrument that measures influences on physical activity. METHODS: A cross-sectional sample of 522 high-risk adults who attended 14 North Carolina primary care family practices were mailed a survey about physical activity and supports of and barriers to physical activity. Risk status was determined by the American Diabetes Association's diabetes risk test. Exploratory principal components factor analyses were conducted on the influences on physical activity instrument. Predictive logistic regression models were used for the dichotomous outcome, meeting recommended Healthy People 2010 activity levels. RESULTS: Of the 258 respondents (56% response rate), 56% reported at least 150 minutes of moderate or vigorous activity per week. Higher education remained a significant demographic predictor of activity (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.08-2.75). Participants were less likely to be physically active if they reported that activity is a low priority (OR, 0.45; 95% CI, 0.23-0.89), were worried about injury (OR, 0.42; 95% CI, 0.25-0.69), or had difficulty finding time for activity (OR, 0.38; 95% CI, 0.17-0.87). CONCLUSION: Participants at risk for diabetes who prioritize physical activity, make time for activity, and are less worried about injury have higher odds of being physically active. Primary care practice and community interventions should consider targeting these areas of success to increase physical activity in sedentary individuals at risk for diabetes.
