Advancing Health Services Research to Eliminate Health Care Disparities.

Findings from health services research highlight continuing health care disparities in the United States, especially in the areas of access to health care and quality of care. Although attention to health care disparities has increased, considerable knowledge gaps still exist. A better understanding of how cultural, behavioral, and health system factors converge and contribute to unequal access and differential care is needed. Research-informed approaches for reducing health care disparities that are feasible and capable of sustained implementation are needed to inform policymakers. More important, for health equity to be achieved, it is essential to create a health care system that provides access, removes barriers to care, and provides equally effective treatment to all persons living in the United States.

Methodological Approaches to Understanding Causes of Health Disparities.

Understanding health disparity causes is an important first step toward developing policies or interventions to eliminate disparities, but their nature makes identifying and addressing their causes challenging. Potential causal factors are often correlated, making it difficult to distinguish their effects. These factors may exist at different organizational levels (e.g., individual, family, neighborhood), each of which needs to be appropriately conceptualized and measured. The processes that generate health disparities may include complex relationships with feedback loops and dynamic properties that traditional statistical models represent poorly. Because of this complexity, identifying disparities' causes and remedies requires integrating findings from multiple methodologies. We highlight analytic methods and designs, multilevel approaches, complex systems modeling techniques, and qualitative methods that should be more broadly employed and adapted to advance health disparities research and identify approaches to mitigate them.

Determining the Long-Term Effectiveness of a Group-Based Physical Activity Program.

OBJECTIVE: In 2015, only half (48%) of older adults in the United States (≥60 years) reported engaging in any kind of physical activity. Few studies examine the impact of evidence-based programs when adopted in community-based settings. The purpose of this study is to assess the effectiveness of EnhanceFitness (EF) upto 12-months. METHOD: EF was offered to older adults in South Florida. A total of 222 EF classes were offered between October 2008 and December 2014. Program consisted of a 1-hour session held three times a week. Even though participation was required for 4 months, 1,295 participants continued the program for at least 1 year. RESULTS: All participants showed significant improvement in outcome measures. A mean change of 1.5, 1.7, and 1.9 was seen in number of chair stands at 4, 8, and 12 months (p < .001), respectively. The number of arm curls performed improved from 16.8 at baseline to 18.8, 18.8, and 19.2 at 4-, 8-, and 12-months, respectively. Participants improved their up-and-go time by decreasing from 9.1 (baseline) to 8.7 (4 months) to 8.6 (12 months; p = .001). DISCUSSION: Randomized controlled trials are commonly used to determine the efficacy of an intervention. These interventions when disseminated at the population level have the potential to benefit large masses. EF is currently offered at more than 700 locations. This tremendous success of EF brings attention to an important question of continuous monitoring of these programs to ensure program consistency and intended outcomes. The model used by the Healthy Aging Regional Collaborative could be replicated by other communities.

Evaluating the Factors Associated With the Completion of a Community-Based Group Exercise Program Among Older Women.

Despite the well-known benefits of exercise, only 50% of U.S. women met recommended physical activity levels in 2014. To combat this issue, the Healthy Aging Regional Collaborative of South Florida has been offering the EnhanceFitness (EF) program in community-based settings since 2008. In the current study, we examined the factors associated with the program completion among older women (≥ 60 years). During the first 4 years, 3,829 older women attended EF sessions. Of these, 924 (24.2%) attended the recommended 32 sessions within first 4 months. Results revealed that women who lived in Miami-Dade County, were ≥ 80 years, and did not report depression and/or risk factors for chronic conditions were more likely to complete EF. Black women were less likely to complete the program. Recognition of these factors might help identify at-risk individuals. More efforts are needed to improve completion rates. Theory-based interventions would allow comprehensive understanding of all factors and, therefore, should be explored in the future.

The influence of gender on colorectal cancer knowledge, screening intention, perceived risk and worry among African Americans in South Florida.

The aim of this study was to examine if gender differences exist for colorectal cancer (CRC) knowledge, intention to screen, perceived risk and cancer worry among African Americans for CRC. African American males and females (N = 336) aged 45 years or older living in southeast Florida were recruited to participate in a cross-sectional survey that assessed intentions to screen as well as CRC knowledge, cancer worry, perceived risk. No significant differences were found between men and women in their intention to screen for CRC or in their worry about cancer. Results did suggest that men and women differed significantly about their understanding of CRC knowledge. Findings also showed that there were differences in perceived risk between genders, with female study participants possessing lower levels of risk than men. Study results suggest that future interventions need to ensure that females understand their risk for CRC and understand the benefits associated with CRC screening. Findings also suggest that interventions promoting CRC screening may need to be tailored if increased participation in CRC screening is to be achieved for women.

Implementation cost analysis of a community-based exercise program for seniors in South Florida.

The objective of the study was to measure the costs of implementing the EnhanceFitness program to elderly residents of South Florida. The Health Foundation of South Florida's Healthy Aging Regional Collaborative implemented EnhanceFitness as part of their initiative to make evidence-based healthy aging programs available to South Florida seniors. Cost data were collected from agencies participating in the delivery of EnhanceFitness classes in South Florida. Cost questionnaires were e-mailed to program coordinators from agencies participating in the delivery of EnhanceFitness classes. Program coordinators worked with accounting staff to complete the questionnaires. Questionnaires were returned via e-mail. Costs were presented from the perspective of participating agencies. Total costs were divided by the number of classes being offered by each agency to determine cost per class per month. Average monthly costs per class were $1,713 during the first year of implementation and $873 during the second year of implementation. The cost measurements, combined with information from the literature on cost savings attributable to EnhanceFitness participation, suggest that EnhanceFitness has the potential to generate a net societal cost savings among program participants. The results are useful for community agencies considering implementing EnhanceFitness for their populations.

Factors associated with the completion of falls prevention program.

Falls and fear of falling can affect independence and quality of life of older adults. Falls prevention programs may help avoiding these issues if completed. Understanding factors that are associated with completion of falls prevention programs is important. To reduce fear of falling and increase activity levels, a Matter of Balance (MOB) and un Asunto de Equilibrio (ADE) workshops were offered to 3420 older adults in South Florida between 1 October 2008 and 31 December 2011. Workshops were conducted in English or Spanish over eight, 2-hour sessions. Participants completed a demographic and a pre-post questionnaire. Factors associated with program completion were identified using logistic regression. For MOB, females were more likely to complete the program (OR = 2.076, P = 0.02). For ADE, females, moderate and extreme interference by falls in social activities were found to affect completion (OR = 2.116, P = 0.001; OR = 2.269, P = 0.003 and OR = 4.133, P = 0.008, respectively). Different factors predicted completion of both programs. Awareness of these factors can help lower the attrition rates, increase benefits and cost effectiveness of program. Future research needs to explore why certain groups had a higher likelihood of completing either program.

Intermediate outcomes of a chronic disease self-management program for Spanish-speaking older adults in South Florida, 2008-2010.

INTRODUCTION: The prevalence and negative health effects of chronic diseases are disproportionately high among Hispanics, the largest minority group in the United States. Self-management of chronic conditions by older adults is a public health priority. The objective of this study was to examine 6-week differences in self-efficacy, time spent performing physical activity, and perceived social and role activities limitations for participants in a chronic disease self-management program for Spanish-speaking older adults, Tomando Control de su Salud (TCDS). METHODS: Through the Healthy Aging Regional Collaborative, 8 area agencies delivered 82 workshops in 62 locations throughout South Florida. Spanish-speaking participants who attended workshops from October 1, 2008, through December 31, 2010, were aged 55 years or older, had at least 1 chronic condition, and completed baseline and post-test surveys were included in analysis (N=682). Workshops consisted of six, 2.5-hour sessions offered once per week for 6 weeks. A self-report survey was administered at baseline and again at the end of program instruction. To assess differences in outcomes, a repeated measures general linear model was used, controlling for agency and baseline general health. RESULTS: All outcomes showed improvement at 6 weeks. Outcomes that improved significantly were self-efficacy to manage disease, perceived social and role activities limitations, time spent walking, and time spent performing other aerobic activities. CONCLUSION: Implementation of TCDS significantly improved 4 of 8 health promotion skills and behaviors of Spanish-speaking older adults in South Florida. A community-based implementation of TCDS has the potential to improve health outcomes for a diverse, Spanish-speaking, older adult population.

Domestic abuse against elder women and perceived barriers to help-seeking.

The study's (n = 447) purposes were to (1) describe relationships of abuser behavior to elder women's perception of barriers to help-seeking; (2) compare fit of model to participants' levels of abuse, race-ethnicity, age, and gender and relationship of identified close other; and (3) determine extent to which the model differentiated relationship of abuser to participant and level of abuse. Analyses identified six factors contributing to the overall barrier score, accounting for 84% of total variance (χ2/df = 1.527, CFI = .989, RMSEA = .034), including three internal and two external factors and a single abuser behavior factor that were invariant across participant characteristic; however, covariances did differ.

Evaluation of a community-based falls prevention program in South Florida, 2008-2009.

INTRODUCTION: Many older adults experience fear of falling, which may reduce participation in routine activities. A Matter of Balance (MOB) and Un Asunto de Equilibrio (ADE) workshops were offered in South Florida to reduce fear of falling and increase activity levels in older adults. The objectives of this study were to evaluate the effectiveness of the lay leader model of the programs in the first year of their implementation and to further report on participant outcome measures. METHODS: We analyzed reach, adoption, and implementation data for participants who attended workshops between October 1, 2008, and December 31, 2009, who were aged 60 years or older, and who had both baseline and posttest outcome data. Workshops were in English and Spanish and consisted of 8 two-hour sessions. Participants completed a 7-item baseline and posttest questionnaire that consisted of a falls management scale, a social activity item, and modified version of Physician-Based Assessment and Counseling on Exercise. We analyzed outcome data on multiple characteristics using a general linear model. A class evaluation questionnaire measured participant satisfaction. RESULTS: Results for 562 participants who provided both baseline and posttest data showed significant improvement on 6 of 7 questions for MOB and all questions for ADE (P < .001). The 391 participants who provided evaluation data indicated that the programs were effective, beneficial, and well organized. CONCLUSION: Lay leaders successfully implemented the programs in community settings. The programs were effective in reducing fear of falling among older adults.

Breast cancer screening practices of safety net clinics: results of a needs assessment study.

BACKGROUND: For low income and uninsured populations, safety net clinics are an important source of health care, including preventive services such as mammography screening. However, little is known about how well breast health is coordinated within the safety net clinic environment and what barriers patients encounter. METHODS: A needs assessment was conducted among eight community-based safety net clinics located in Montgomery County, Maryland to learn about breast cancer referral and screening procedures. Structured in-depth interviews were conducted with clinic staff during the summer of 2008. RESULTS: Safety net clinics reported that they routinely identified women who need mammography screening and referred women to mammography screening facilities. However, clinics were not aware of the limited number of free or low cost mammography screening slots available in the county or the waiting time to receive mammography services. Overall, screening barriers were common in the safety net system and only a few procedures were in place to help women overcome these barriers. CONCLUSION: Safety net clinics face multiple barriers in providing and coordinating breast cancer screening services for low income or uninsured patients. These barriers prevent the efficient allocation of mammography screening services and prevent underserved women from accessing an important preventive health service.

Colorectal cancer screening adherence in African-American men and women 50 years of age and older living in Maryland.

African Americans experience disproportionate incidence and mortality rates from colorectal cancer (CRC). This health disparity is partially explained by low participation in screening. This study aimed to identify factors influencing adherence to colorectal cancer screening among African Americans. Telephone interviews were conducted with African Americans living in Maryland (57% response rate). A total of 504 respondents agreed to participate. The survey primarily assessed participation in CRC screening, health beliefs and attitudes about CRC screening, and demographics. Nearly 77% of respondents reported being adherent to CRC screening guidelines. Of those not adherent, nearly 50% reported not ever receiving a physician recommendation to be screened. Having health insurance was a strong correlate of adherence. Study participants with greater perceived CRC risk were more likely to be adherent. Further, those who reported that they were caregivers were less likely to be adherent to screening. Findings indicate that those who were the primary care takers of children or disabled persons were less likely to participate in CRC screening. Efforts are needed to ensure that caregivers do not neglect their own preventive health, including CRC screening. Further, access to care and health insurance coverage also appear to be an important factor for participation in CRC screening. Ensuring that those who do not have adequate healthcare coverage are not excluded from participation in CRC screening due to cost should be an important priority if reduction in CRC health disparity is to be achieved.

Health care provider tobacco cessation counseling among current African American tobacco users.

Tobacco use is the leading cause of preventable mortality and morbidity in the United States. Patients advised to quit use of tobacco products by their health care providers are more likely to quit, yet it has been documented that patients are not receiving this advice. The aim of this study was to investigate whether or not current African American tobacco users were receiving provider-initiated advice to quit. A cross-sectional survey identified 245 self-reported African American tobacco users residing in Maryland. Study variables collected included sociodemographics, access to care, smoking status, and assessed if tobacco cessation counseling was ever provided. Among those surveyed, only 42% reported ever being counseled to quit tobacco use and, of those who had a recent clinical encounter (within the past year), only 20% reported being counseled. Multivariate logistic regression identified that having a regular source of health care, living in an urban setting, and being female increased chances of being advised to quit tobacco use. Overall, findings indicate that African Americans are not being screened or receiving cessation counseling as recommended by leading health agencies. Health care provider training to promote better integration of tobacco screening and tobacco cessation counseling during the patient encounter is needed.

Development and evaluation of a web-based breast cancer cultural competency course for primary healthcare providers.

BACKGROUND: To develop and evaluate a continuing medical education (CME) course aimed at improving healthcare provider knowledge about breast cancer health disparities and the importance of cross-cultural communication in provider-patient interactions about breast cancer screening. METHODS: An interactive web-based CME course was developed and contained information about breast cancer disparities, the role of culture in healthcare decision making, and demonstrated a model of cross-cultural communication. A single group pre-/post-test design was used to assess knowledge changes. Data on user satisfaction was also collected. RESULTS: In all, 132 participants registered for the CME with 103 completing both assessments. Differences between pre-/post-test show a significant increase in knowledge (70% vs. 94%; p < .001). Ninety-five percent of participants agreed that the web based training was an appropriate tool to train healthcare providers about cultural competency and health disparities. CONCLUSION: There was an overall high level of satisfaction among all users. Users felt that learning objectives were met and the web-based format was appropriate and easy to use and suggests that web-based CME formats are an appropriate tool to teach cultural competency skills. However, more information is needed to understand how the CME impacted practice behaviors.

Cancer prevention and control: a role for medical assistants?

This study aimed to assess medical assistants' willingness to engage in patient education and counseling about cancer prevention and control. A questionnaire was mailed to 402 medical assistants living in Maryland in June 2006 to assess attitudes and practices about counseling and educating patients on cancer prevention and control topics. Findings reveal that medical assistants are engaging patients in discussions about cancer prevention, with diet/nutrition and exercise being most often discussed. Medical assistants are willing to counsel and educate patients on cancer prevention and control topics.

Colorectal cancer screening preferences among African Americans: which screening test is preferred?

African Americans are diagnosed at late stages and suffer disproportionately higher mortality rates from colorectal cancer (CRC). Increasing their participation in CRC screening can help reduce these disparities. In-depth personal interviews were conducted with 60 African Americans to understand if CRC test preferences exist and to identify what attributes of screening tests influence test preferences. Most individuals interviewed preferred colonoscopy as compared to FOBT. Previous participation in CRC screening influenced how individuals made decisions about CRC screening. Enabling individuals without CRC screening experience to first complete FOBT might prepare them to later participate in colonoscopy screening.

Preventive health patient education and counseling: a role for medical assistants?

Collaborative office-based team approaches may provide a unique means to increase the low rates of preventive services delivery. This study aimed to assess what role medical assistants may have in the delivery of preventive services to patients. A 35-item questionnaire was mailed to 402 medical assistants living in Maryland in July 2005. The questionnaire assessed current levels of preventive service delivery, attitudes toward patient education, and willingness to educate patients. A total of 281 surveys were returned for a response rate of 71%. Study findings revealed that a fair amount of preventive services delivery was already being delivered in health care settings by medical assistants. Medical assistants were more likely to discuss diet/nutrition and exercise with patients. Findings also highlight that medical assistants held positive beliefs about educating patients and nearly all respondents (90%) were willing to deliver preventive services. Given the increased presence of medical assistants in the health care setting, it may be feasible to delegate some preventive care delivery to this willing team member. Future research needs to explore how to better incorporate and delegate preventive health care delivery in medical settings.

Screening patients with a family history of colorectal cancer.

OBJECTIVES: To compare screening practices and beliefs in patients with and without a clinically important family history. DESIGN: We mailed a brief questionnaire asking about family history and a second, longer survey asking about knowledge of and beliefs about colorectal cancer to all respondents with a family history and a random sample of respondents without a family history of colorectal cancer. We reviewed electronic medical records for screening examinations and recording of family history. PARTICIPANTS: One thousand eight hundred seventy of 6,807 randomly selected patients ages 35-55 years who had been continuously enrolled in a large multispecialty group practice for at least 5 years. MEASUREMENTS: Recognition of increased risk, screening practices, and beliefs-all according to strength of family history and patient's age. RESULTS: Nineteen percent of respondents reported a family history of colorectal cancer. In 11%, this history was strong enough to warrant screening before age 50 years. However, only 39% (95% CI 36, 42) of respondents under the age of 50 years said they had been asked about family history and only 45% of those with a strong family history of colorectal cancer had been screened appropriately. Forty-six percent of patients with a strong family history did not know that they should be screened at a younger age than average risk people. Medical records mentioned family history of colorectal cancer in 59% of patients reporting a family history. CONCLUSIONS: More efforts are needed to translate information about family history of colorectal cancer into the care of patients.
