Variations in provider conceptions of integrative medicine.

Consumers often turn to complementary and alternative medicine (CAM) and use it concurrently with conventional medicine to treat illnesses and promote wellness. However, prior studies demonstrate that these two paradigms are often not combined effectively. Consumers often do not tell physicians about CAM treatments or CAM practitioners about conventional treatments that they are using. This can lead to inefficient care and/or adverse interactions. There is also a lack of consensus about the structure and practice of integrative medicine among the various types of practitioners. This qualitative study aimed to identify key domains and develop a conceptual model of integrative medicine at the provider level, using a grounded theory approach. Purposive sampling was used to select 50 practitioners, including acupuncturists, chiropractors, internists/family practitioners, and physician acupuncturists in private practice and at academic medical centers in Los Angeles. We conducted semi-structured, in-depth interviews with practitioners and then identified core statements that describe practitioners' attitudes and behaviors toward integrative medicine. Core statements were free pile sorted to ascertain key domains of integrative medicine. Four key domains of integrative medicine were identified at the provider level: attitudes, knowledge, referral, and practice. Provider age, training, and practice setting also emerged as important factors in determining clinicians' "orientation" toward integrative medicine. "Dual-trained" practitioners, such as physician acupuncturists, exemplified clinicians with a greater orientation toward integrative medicine. They advocated an open-minded perspective about other healing traditions, promoting co-management with and making referrals to practitioners of other paradigms, and treating patients with both CAM and conventional healing modalities.

Emotional distress and mental health service use among urban homeless adolescents.

The Expanded Behavioral Model for Vulnerable Populations was used to examine the predisposing, enabling, and need factors associated with mental health service use in a homeless adolescent sample (N = 688). Among all youth, 32% perceived a need for help with mental health problems and 15% met Brief-Symptom Inventory (BSI) criteria for emotional distress. The rate of mental health service use in our sample was 32%. One enabling factor, having a case manager/discussed mental health concerns, and one need factor, which met criteria for BSI, were found to be associated with mental health service use in the past 3 months. The majority of youth who used mental health services had obtained services from crisis centers. Among those who perceived a need for help with mental health problems but who did not use services, the most common barrier was not knowing where to go or what service to use (57%). These findings suggest that due to the high prevalence of mental health problems among homeless youth, it would be helpful for service providers coming into contact with youth to make them aware of existing community resources for mental health services; making youth aware of these resources may in turn decrease the rate of crisis center use and instead allow youth to receive mental health services in outpatient settings that provide continuity of care.

Variation in complementary and alternative medicine (CAM) use across racial/ethnic groups and the development of ethnic-specific measures of CAM use.

OBJECTIVES: The use of complementary and alternative medicine (CAM) is likely to vary among racial/ethnic groups because its use is related to cultural and health beliefs. Understanding patterns of CAM use among ethnic groups could inform clinical practice and the study of CAM use in a diverse population. The authors compared CAM use among Asian-Americans, American Indians, African Americans, Latinos, whites, and other racial/ethnic groups in order to develop ethnic-specific measures of CAM use and explore factors associated with such CAM use across ethnic groups. DESIGN: A cross-sectional survey of a sample of 9187 adults representative of the California population was performed. OUTCOME MEASURES: Ethnic-specific constructs for Asian-Americans, American Indians, African Americans, Latinos, and whites were devised. RESULTS: The authors identified ethnic-specific CAM modalities for each ethnic group. Demographic and clinical factors associated with use of ethnic-specific CAM differed from the predictors of overall CAM use in the general population and varied by ethnicity. CONCLUSIONS: Patterns of CAM use and ethnic-specific CAM use vary across racial/ethnic groups. Evaluation of CAM use in ethnically diverse populations should recognize ethnic-specific modalities and variation across ethnicity.

Psychotropic medication use in a national probability sample of children in the child welfare system.

OBJECTIVES: The aim of this study was to estimate the point prevalence of psychotropic medication use, and to describe relationships between child-level characteristics, provider type, and medication use among children in the child welfare system. METHODS: The National Survey of Child and Adolescent Well-Being is the first nationally representative study of children coming into contact with the child welfare system. We used data from its baseline and 12-month follow-up waves, and conducted weighted bivariate analyses on a sample of 3114 children and adolescents, 87% of whom were residing in-home. RESULTS: Overall, 13.5% of children in child welfare were taking psychotropic medications in 2001-2002. Older age, male gender, Caucasian race/ethnicity, history of physical abuse, public insurance, and borderline scores on the internalizing and externalizing subscales of the Child Behavior Checklist were associated with higher proportions of medication use. African-American and Latino ethnicities, and a history of neglect, were associated with lower proportions of medication use. CONCLUSIONS: These national estimates suggest that children in child welfare settings are receiving psychotropic medications at a rate between 2 and 3 times that of children treated in the community. This suggests a need to further understand the prescribing of psychotropic medications for child welfare children.

A Self-Report Measure of Clinicians' Orientation toward Integrative Medicine.

OBJECTIVE: Patients in the U.S. often turn to complementary and alternative medicine (CAM) and may use it concurrently with conventional medicine to treat illness and promote wellness. However, clinicians vary in their openness to the merging of treatment paradigms. Because integration of CAM with conventional medicine can have important implications for health care, we developed a survey instrument to assess clinicians' orientation toward integrative medicine. STUDY SETTING: A convenience sample of 294 acupuncturists, chiropractors, primary care physicians, and physician acupuncturists in academic and community settings in California. DATA COLLECTION METHODS: We used a qualitative analysis of structured interviews to develop a conceptual model of integrative medicine at the provider level. Based on this conceptual model, we developed a 30-item survey (IM-30) to assess five domains of clinicians' orientation toward integrative medicine: openness, readiness to refer, learning from alternate paradigms, patient-centered care, and safety of integration. PRINCIPAL FINDINGS: Two hundred and two clinicians (69 percent response rate) returned the survey. The internal consistency reliability for the 30-item total scale and the five subscales ranged from 0.71 to 0.90. Item-scale correlations for the five subscales were higher for the hypothesized subscale than other subscales 75 percent or more of the time. Construct validity was supported by the association of the IM-30 total scale score (0-100 possible range, with a higher score indicative of greater orientation toward integrative medicine) with hypothesized constructs: physician acupuncturists scored higher than physicians (71 versus 50, p<.001), dual-trained practitioners scored higher than single-trained practitioners (71 versus 62, p<.001), and practitioners' self-perceived "integrativeness" was significantly correlated (r=0.60, p<.001) with the IM-30 total score. CONCLUSION: This study provides support for the reliability and validity of the IM-30 as a measure of clinicians' orientation toward integrative medicine. The IM-30 survey, which we estimate as requiring 5 minutes to complete, can be administered to both conventional and CAM clinicians.

Racial and ethnic disparities in access to physicians with HIV-related expertise.

OBJECTIVE: Professional medical associations recommend that physicians who treat patients with human immunodeficiency virus (HIV) have a measurable form of disease-specific expertise, such as high HIV patient volume or infectious diseases certification. Although it is known that racial/ethnic minorities generally have worse access to care than do whites, previous work has not examined disparities in the use of physicians with HIV-related expertise. DESIGN, SETTING, AND PARTICIPANTS: We linked data from a prospective cohort study of 2,207 persons with HIV receiving care in the United States with a cross-sectional survey of 404 physicians caring for them. Using multivariate analysis, we estimated the association of patient race/ethnicity with the experience and training of their physicians, controlling for health status, socioeconomic status, demographic characteristics, and geographic variation in provider supply. RESULTS: Compared with white patients, African Americans were less likely to have an infectious diseases specialist as a regular source of care (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.37 to 0.95). Persons of Alaskan Native, American Indian, Asian, Pacific Islander, or mixed racial background were also less likely than whites to have an infectious diseases specialist (OR, 0.44; 95% CI, 0.23 to 0.83). Conversely, Latino patients had physicians whose HIV patient volume was, on average, 24% higher than the physicians of white patients (incident rate ratio, 1.24; 95% CI, 1.03 to 1.50). CONCLUSIONS: Some groups of racial/ethnic minorities are less likely than are whites to have infectious diseases specialists as a regular source of care. The finding that the physicians of Latino patients had relatively higher HIV caseloads suggests that this particular patient subpopulation has access to HIV expertise. Further work to explain racial/ethnic differences in access to physicians will help in the design of programs and policies to eliminate them.

Do specialist self-referral insurance policies improve access to HIV-experienced physicians as a regular source of care?

Health insurance policies that require prior authorization for specialty care may be detrimental to persons with HIV, according to evidence that having a regular physician with HIV expertise leads to improved patient outcomes. The objective of this study is to determine whether HIV patients who can self-refer to specialists are more likely to have physicians who mainly treat HIV. The authors analyze cross-sectional survey data from the HIV Costs and Services Utilization Study. At baseline, 67 percent of patients had insurance that permitted self-referral. In multivariate analyses, being able to self-refer was associated with an 8-12 percent increased likelihood of having a physician at a regular source of care that mainly treats patients with HIV. Patients who can self-refer are more likely to have HIV-experienced physicians than are patients who need prior authorization. Insurance policies allowing self-referral to specialists may result in HIV patients seeing physicians with clinical expertise relevant to HIV care.

A longitudinal analysis of unmet need for oral treatment in a national sample of medical HIV patients.

This longitudinal study examines perceived unmet dental need in a nationally representative probability sample of HIV-infected persons in medical care. A logistic regression analysis modeled the relationship between unmet need and explanatory variables. We estimate that 40% of HIV/AIDS patients report an unmet need associated with being male, being unemployed, injecting drugs, being heterosexual, lacking dental insurance, and having less education. Disparities in unmet need are related to socioeconomic status rather than to disease stage or ethnicity.

Pipeline, profession, and practice program: evaluating change in dental education.

This article describes the conceptual and analytical framework that will be used to assess the effectiveness of the Pipeline, Profession, and Practice: Community-Based Dental Education Program. The evaluation will use a mixed method qualitative and quantitative data collection, analysis, and triangulation. Baseline measures are reported using data from the 2003 ADEA survey of dental school seniors. Baseline measures show the dental schools are confronting a major recruitment challenge that will require short and long pipeline efforts to attract and retain underrepresented and low-income (URM/LI) persons. Gaps were found between the perceptions of URM and non-URM students in the adequacy of the curricula. The majority of all seniors described the current extramural clinical rotations as positive experiences, but URMs were more likely to report the experience improved their ability to care for diverse groups.

Racial and ethnic differences in patients' preferences for initial care by specialists.

PURPOSE: To examine racial and ethnic differences in patients' preferences for initial care by specialists, and to determine whether trust in the physician and health beliefs account for these differences. METHODS: We conducted a cross-sectional study of 646 patients in the waiting room of three academic-based internal medicine outpatient practices. We asked subjects about their preference to see their primary care provider or a specialist first regarding the actual health problem that had brought them to see their physician as well as regarding three hypothetical scenarios (2 weeks of new-onset exertional chest pain, 2 months of knee pain, and rash for 4 weeks). We examined the relation among patients' preference for initial care by a specialist and their demographic characteristics, global ratings of their primary care physician and health plan, trust in their primary care physician, and other health beliefs and attitudes. RESULTS: Averaged for the three scenarios and actual health problem, 13% of patients preferred to see a specialist first. Adjusting for all other covariates, blacks (risk ratio [RR] = 0.55; 95% confidence interval [CI]: 0.20 to 0.92) and Asians (RR = 0.46; 95% CI: 0.19 to 0.75) were much less likely to prefer a specialist than were whites. Patients with less confidence in their primary care physician and greater certainty about needed tests and treatments were more likely to prefer a specialist. These variables, however, did not explain the difference in preference for specialist care among blacks, Asians, and whites. CONCLUSION: Blacks and Asians are less likely than whites to prefer initial care by a specialist. Future studies should examine whether differences in preference for care lead minorities to underutilize appropriate specialty care or lead whites to overuse specialty care.

Disparities in HIV treatment and physician attitudes about delaying protease inhibitors for nonadherent patients.

BACKGROUND: Current HIV treatment guidelines recommend delaying antiretroviral therapy for nonadherent patients, which some fear may disproportionately affect certain populations and contribute to disparities in care. OBJECTIVES: To examine the relationship of physician's attitude toward prescribing protease inhibitors (PIs) to nonadherent patients with disparities in PI use and with health outcomes. DESIGN: Prospective cohort study. PATIENTS AND SETTING: A national probability sample of HIV-infected adults in the United States and their health care providers was surveyed between January 1996 and January 1998. We analyzed data on 1717 patients eligible for PI treatment and the 367 providers who cared for them. MEASUREMENTS: Providers' attitude toward prescribing PIs to nonadherent patients, time until patients' first receipt of PIs, mortality, and physical health status. MAIN RESULTS: Eighty-nine percent of providers agreed that patient adherence is important in their decision to prescribe PIs (Selective) while 11% disagreed (Nonselective). Patients who had a Selective provider received PIs later than those with a Nonselective provider (P =.05). Adjusting for patient demographics and health characteristics and provider demographics, HIV knowledge, and experience, Latinos, women, and poor patients received PIs later if their provider had a Selective attitude but as soon as others if their provider had a Nonselective attitude. African-American patients received PIs later than whites, irrespective of their providers' prescribing attitude. Patients with Selective providers had similar odds of mortality than those with Nonselective providers (odds ratio, 1.1; 95% confidence interval, 0.6 to 2.0), but had slightly worse adjusted physical health status at follow-up (49.1 vs 50.4, respectively; P =.04), after controlling for baseline physical health status and other patient and provider covariates. CONCLUSIONS: Most providers consider patient adherence an important factor in their decision to prescribe PIs. This attitude appears to account for the relatively later use of PI treatment among Latinos, women, and the poor. Given the rising HIV infection rates among minorities, women, and the poor, further investigation of this treatment strategy and its impact on HIV resistance and outcomes is warranted.

Sociodemographic differences in access to care among Hispanic patients who are HIV infected in the United States.

This study evaluated associations between sociodemographic factors and access to care, use of highly active antiretroviral therapy, and patients' ratings of care among Hispanic patients who are HIV infected; we used data from the HIV Cost and Services Utilization Study. Gender, insurance, mode of exposure, and geographic region were associated with access to medical care. Researchers and policymakers should consider sociodemographic factors among Hispanic patients who are HIV positive when designing and prioritizing interventions to improve access to care.

A framework for evaluating safety-net and other community-level factors on access for low-income populations.

The framework presented in this article extends the Andersen behavioral model of health services utilization research to examine the effects of contextual determinants of access. A conceptual framework is suggested for selecting and constructing contextual (or community-level) variables representing the social, economic, structural, and public policy environment that influence low-income people's use of medical care. Contextual variables capture the characteristics of the population that disproportionately relies on the health care safety net, the public policy support for low-income and safety-net populations, and the structure of the health care market and safety-net services within that market. Until recently, the literature in this area has been largely qualitative and descriptive and few multivariate studies comprehensively investigated the contextual determinants of access. The comprehensive and systematic approach suggested by the framework will enable researchers to strengthen the external validity of results by accounting for the influence of a consistent set of contextual factors across locations and populations. A subsequent article in this issue of Inquiry applies the framework to examine access to ambulatory care for low-income adults, both insured and uninsured.

Effects of community factors on access to ambulatory care for lower-income adults in large urban communities.

This study examines the effects of community-level and individual-level factors on access to ambulatory care for lower-income adults in 54 urban metropolitan statistical areas in the United States. Drawing on a conceptual behavioral and structural framework of access, the authors developed multivariate models for insured and uninsured lower-income adults to assess the adjusted effects of community- and individual-level factors on two indicators of access: having a usual source of care, and having at least one physician visit in the past year. Several community factors influenced access, but they did so differently for insured and uninsured adults and for the two measures of access used. The findings of this sttudy confirm that public policies and community environment have measurable and substantial impacts on access to care, and that expanded public resources, such as Medicaid payments and safety-net clinics, can lead to measurable improvements in access for vulnerable populations residing in large urban areas.

Complementary and alternative medicine use and substitution for conventional therapy by HIV-infected patients.

BACKGROUND: HIV-infected patients commonly use complementary and alternative medicine (CAM), but it is not known how often CAM is used as a complement or as a substitute for conventional HIV therapy. OBJECTIVES: To evaluate the prevalence and factors associated with CAM use with potential for adverse effects and CAM substitution for conventional HIV medication. DESIGN AND PARTICIPANTS: Cross-sectional survey of U.S. national probability sample of HIV-infected patients (2,466 adults) in care from December 1996 to July 1997. MAIN OUTCOME VARIABLES: Any CAM use, CAM use with potential for adverse effects, and use of CAM as a substitute for conventional HIV therapy. Substitution was defined as replacement of some or all conventional HIV medications with CAM. RESULTS: Fifty-three percent of patients had recently used at least one type of CAM. One quarter of patients used CAM with the potential for adverse effects, and one-third had not discussed such use with their health care provider. Patients with a greater desire for medical information and involvement in medical decision making and with a negative attitude toward antiretrovirals were more likely to use CAM. Three percent of patients substituted CAM for conventional HIV therapy. They were more likely to desire involvement in medical decision-making (odds ratio, 1.8; 95% confidence interval, 1.0-3.2) and to have a negative attitude toward antiretrovirals (odds ratio, 7.8; 95% confidence interval, 3.0-19.0). CONCLUSIONS: Physicians should openly ask HIV-infected patients about CAM use to prevent adverse effects and to identify CAM substitution for conventional HIV therapy.

Health care for homeless women.

OBJECTIVE: Homelessness is a significant and growing problem in the United States. Women and families are the fastest growing segments of the homeless population. Homelessness increases the risk of having health problems and encountering barriers to care. This study determines how much perceived unmet need for medical care there is among homeless women, what homeless women perceive to be barriers to health care, and how barriers and other factors are associated with unmet needs. DESIGN: Cross-sectional study of homeless women, utilizing structured interviews. SETTING AND PARTICIPANTS: Community-based probability sample of 974 homeless women aged 15 to 44 years. MAIN OUTCOME MEASURES: Perceived unmet need for medical care in the past 60 days. Relationship between unmet need and demographic variables, place of stay, source of health care, insurance, and perceived barriers to care. RESULTS: Of the 974 women, 37% reported unmet need for medical care. Controlling for other factors, the odds of unmet need were lower among those with a regular source of care (odds ratio [OR] to.35, 95% confidence interval [CI],.21 to 58), while having health insurance was not significantly associated. The odds of unmet need were higher among those who experienced the barriers: not knowing where to go (OR 2.27, 95% CI, 1.40 to 3.69), long office waiting times (OR 1.89, 95% CI 1.27 to 2.83) and being too sick to seek care (OR 2.03, 95% CI, 1.14 to 3.62). CONCLUSIONS: There is significant unmet need for medical care among homeless women. Having a regular source of care was more important than health insurance in lowering the odds of unmet need. Homeless women must be educated regarding sources of care, and clinics serving the homeless must decrease waiting times.

Use of faith-based social service providers in a representative sample of urban homeless women.

There are few quantitative studies on the characteristics of homeless persons who use faith-based social service providers. To help address the lack of information in this area, we analyzed survey data on 974 participants in the University of California at Los Angeles (UCLA) Homeless Women's Health Study, a representative sample of homeless women at shelters and meal programs in Los Angeles County. The primary objective of this analysis was to estimate the association of religious affiliation, race/ethnicity, income, and other client characteristics with the use of faith-based programs. In interviews at 78 homeless shelters and meal programs, study respondents provided information about their religious affiliation and other social and demographic characteristics. The names of the organizations were examined, and those with names that referenced specific religions or contained words connoting religiosity were designated as "faith based." At the time they were selected for study participation, 52% of respondents were using the services of faith-based providers. In multivariate logistic regression analysis, lower odds of using these providers were estimated for participants with no religious affiliation (compared with Christian respondents) and for African Americans and Latinas (compared with whites). There is evidence of systematic differences between the clients of faith-based and secular social service providers. The benefits of increased funding through a federal faith-based policy initiative may accrue primarily to subgroups of clients already using faith-based programs.
