Effectiveness of Texas Children's Hospital's Saturday Wellness Program for Children with special health care needs

Children with Special Health Care Needs comprise approximately 13% of children within the state of Texas. In addition to their primary diagnosis, it is estimated that approximately 18% of these children with special health care needs are overweight. Many times parents of children with special health care needs are extremely busy dealing with the daily responsibilities required to care for a child with a chronic illness, and thus, lose connections with their local communities and available resources for health needs such as obesity. Texas Children’s Hospital’s Wellness Program for Children with Special Health Care Needs is a family-centered wellness program to prevent obesity in this population; however, no formal evaluation of the program has been conducted. The purpose of this study was to assess the effectiveness of the Texas Children’s Saturday Wellness Program on weight status, nutrition knowledge, and the frequency of physical activity of children who participated in the program. A secondary data analysis was conducted with 50 children with special health care needs and their families who participated in the program during 2007 and 2008. A pre post-test study design was used with data collected immediately before and after participation in the 4 week program. Data measures included demographics (age, race, etc.), anthropometrics (height and weight), a quality of life survey focusing on nutrition and physical activity behaviors, and a knowledge survey on physical activity and nutrition. Of 50 participants, 33 (66%) completed the program. Children participating in the program showed a significant decrease in BMI (mean=29.83 to mean=29.22, BMI z score p<0.01), as well as frequency of physical activity (p<0.05) and knowledge (p<0.01). Texas Children’s Hospital’s wellness program for children with special health care needs provided a promising structure for a wellness program within a multi-ethnic special needs population; however, long term effect research is needed with a larger sample size and more comprehensive outcomes and process measures. Nonetheless, this program indicates the effectiveness and feasibility of a family-based approach to weight loss in children with special needs.^

Refugees from Myanmar and their health care needs in the US: A qualitative study at a refugee-resettlement agency

In response to the recent rapid influx of refugees from Myanmar, Interfaith Ministries for Greater Houston (IM), a refugee resettlement agency, started to support them in June 2007. The study looked at the refugees' perspectives and identified the gaps in their understanding on US health care system, health seeking behaviors and challenges in utilizing health care in United States. The major issues identified were non-compliance with tuberculosis prevention medication due to barriers in obtaining medication refills, barriers in accessing specialty care services, transportation issues, written and oral language barrier, difficulties in the application for and use of Medicaid and Gold Card, misunderstanding of emergency health services, lack of resources for health education, self-treatment with Western medicine and income too low to buy private health insurance. In order to transform them to healthy citizens able to contribute to the US workforce, several multi-faceted and comprehensive approaches and better coordination among agencies are recommended. ^

Using small area estimation and geographic information systems technology to target health services for the uninsured

The three articles that comprise this dissertation describe how small area estimation and geographic information systems (GIS) technologies can be integrated to provide useful information about the number of uninsured and where they are located. Comprehensive data about the numbers and characteristics of the uninsured are typically only available from surveys. Utilization and administrative data are poor proxies from which to develop this information. Those who cannot access services are unlikely to be fully captured, either by health care provider utilization data or by state and local administrative data. In the absence of direct measures, a well-developed estimation of the local uninsured count or rate can prove valuable when assessing the unmet health service needs of this population. However, the fact that these are “estimates” increases the chances that results will be rejected or, at best, treated with suspicion. The visual impact and spatial analysis capabilities afforded by geographic information systems (GIS) technology can strengthen the likelihood of acceptance of area estimates by those most likely to benefit from the information, including health planners and policy makers. ^ The first article describes how uninsured estimates are currently being performed in the Houston metropolitan region. It details the synthetic model used to calculate numbers and percentages of uninsured, and how the resulting estimates are integrated into a GIS. The second article compares the estimation method of the first article with one currently used by the Texas State Data Center to estimate numbers of uninsured for all Texas counties. Estimates are developed for census tracts in Harris County, using both models with the same data sets. The results are statistically compared. The third article describes a new, revised synthetic method that is being tested to provide uninsured estimates at sub-county levels for eight counties in the Houston metropolitan area. It is being designed to replicate the same categorical results provided by a current U.S. Census Bureau estimation method. The estimates calculated by this revised model are compared to the most recent U.S. Census Bureau estimates, using the same areas and population categories. ^

Barriers to adolescent and young men's access of reproductive health care

Purpose. The purpose of this study was to identify the health needs and barriers that young men face in accessing health care and family planning services and to identify what health centers can do to attract young men to the clinic. A focus group format was used to elicit ideas from participants. ^ Methods. Forty-eight young men participated in nine focus groups. The young men were asked about the health issues they have, the barriers they face in accessing reproductive health care, and what clinics can do to attract young men to the clinic. Thematic analysis principles were used to identify the main themes that emerged in the focus groups. ^ Results. Sexually transmitted infections (STIs), mental health problems, and drug use were the major health issues that were mentioned in the majority of the focus groups. The main barriers discussed in the focus groups were attitudinal factors such as young men thinking it is unmanly to seek help, emotional factors such as young men not seeking help because of their ego or pride, and institutional factors such as the location of the clinic. The main suggestions for improvements in the health clinic included decreasing waiting times, emphasizing the fact that the clinics are free for males, having more female nurses, and encouraging clinic staff to treat the young men with respect. Young men suggested advertising and promoting the clinic in schools, in the community, and through the media. Focus group participants also provided their input about the design and format of the clinic flyer. ^ Conclusions. Many studies focus on the reproductive health care needs of adolescent and young females. This study has helped to show that young men also have health care needs and face barriers to accessing reproductive health care services.^

Social support, health status and health services utilization among the noninstitutionalized elderly: An analysis of the Supplement on Aging to the 1984 national health interview survey

The association between Social Support, Health Status, and Health Services Utilization of the elderly, was explored based on the analysis of data from the Supplement on Aging to the National Health Interview Survey, 1984 (N = 11,497) using a modified framework of Aday and Andersen's Expanded Behavioral Model. The results suggested that Social Support as operationalized in this study was an independent determinant of the use of health services. The quantity of social activities and the use of community services were the two most consistent determinants across different types of health services use.^ The effects of social support on the use of health services were broken down into three components to facilitate explanations of the mechanisms through which social support operated. The Predisposing and Enabling component of Social Support had independent, although not uniform, effects on the use of health services. Only slight substitute effects of social support were detected. These included the substitution of the use of senior centers for longer stay in the hospital and the substitution of help with IADL problems for the use of formal home care services.^ The effect of financial support on the use of health services was found to be different for middle and low income populations. This differential effect was also found for the presence of intimate networks, the frequencies of interaction with children and the perceived availability of support among urban/rural, male/female and white/non-white subgroups.^ The study also suggested that the selection of appropriate Health Status measures should be based on the type of Health Services Utilization in which a researcher is interested. The level of physical function limitation and role activity limitation were the two most consistent predictors of the volume of physician visits, number of hospital days, and average length of stay in the hospital during the past year.^ Some alternative hypotheses were also raised and evaluated, when possible. The impacts of the complex sample design, the reliability and validity of the measures and other limitations of this analysis were also discussed. Finally, a revised framework was proposed and discussed based on the analysis. Some policy implications and suggestions for future study were also presented. ^

Race and discourse analysis: Building a dialogue in health service research and health care settings

Using a framework for discourse analysis developed by Van Dijk, the investigator will pinpoint the pathological forms of discourse on race, defined as 'race talk' in three professional domains: health services research, public health provider organizations, and literature on multiculturalism. Attention will then turn to developing an analytical strategy for building more meaningful dialogue on race. The retrieval of potential resources for dialogue will be drawn from the third domain. Analysis will focus on enhancing the prospects of converting 'race talk' into dialogue. This will be accomplished by characterizing the normative preconditions as formal procedural requirements for dialogue and then supplementing these conditions with others related specifically to race. From here, the practical implications of combining procedural requirements and resources in each of the domains will be considered. Finally, the author will attempt to determine how these selected resources might be employed to transform 'race talk' in practice and lay the groundwork for a dialogue of understanding. ^

Community participation in health services

This study critically analyzes and synthesizes community participation (CP) theory across disciplines, defining and beginning to map out the elements of CP according to a preliminary framework of structure, process, intermediate outcomes, and ultimate outcomes. The first study component sought to determine the impact of Sight N' Soul, a CP project utilizing neighborhood health workers (NHWs), on appointment missing in an indigent urban African-American population. It found that persons entering the vision care system through contact with an NEW were about a third less likely to miss an appointment than those persons entering the system through some other avenue. While theory in this area remains too poorly developed to hypothesize causal relationships between structure, process, and outcomes, a summary of the elements of Sight N' Soul's structure and process both developed the preliminary framework and serves as a first step to mapping these relationships. The second component of the study uncovered the elements of structure and process that may contribute to a sustained egalitarian partnership between community people and professionals, a CP program called Project HEAL. Elements of Project HEAL's structure and process included a shared belief in the program; spirituality; contribution, ownership, and reciprocation; a feeling of family; making it together; honesty, trust, and openness about conflict; the inevitability of uncertainty and change; and the guiding interactional principles of respect; love, care, and compassion; and personal responsibility. The third component analyzed the existing literature, identifying and addressing gaps and inconsistencies and highlighting areas needing more highly developed ethical analysis. Focal issues include the political, economic, and historical context of CP; the power of naming; the issue of purpose; the nature of community; the power to muster and allocate resources; and the need to move to a systems view of health and well-being, expanding our understanding of the universe of potential outcomes of CP, including iatrogenic outcomes. Intermediate outcomes might include change in community, program, and individual capacity, as well as improved health care delivery. Ultimate outcomes include increased positive interdependencies and opportunities for contribution; improved mental, physical, and spiritual health; increased social justice; and decreased exploitation. ^

How health care delay and avoidance decisions are affected by finances and health insurance

Objective. To identify how an individual's finances and health insurance coverage affects their decision whether to avoid or delay medical care. Methods. Secondary data analysis of The Effects of Financial and Insurance Considerations on Health Care Utilization 2007 telephone survey data. Study inclusion criteria. 18 years old, Harris County resident, and had a need for medical care within the past year. Post weighing was done to correct for non-response bias. Results. Survey decision makers were predominately minorities (60%), Female (70%), and insured (71%). Ninety-two percent of participants sought care when needed, however, of this population 39% delayed medical care. Fifty-six percent of participants who delayed medical care sought care in the Doctor's office. For those who replied "Yes" to considering health insurance and finances in deciding to avoid medical care, 61% stated that they were confused about their insurance coverage as the explanation why. Fifty-five percent of Respondents indicated that delaying medical care was due to not knowing whether medical care was necessary. Conclusion. Additional research needs to be conducted to examine the relationship between onset of medical symptoms and final medical diagnosis to identify whether survey participants who delayed or avoided medical care actions were appropriate responses to their initial medical symptoms and final diagnosis. ^

Has implementation of integrated mental health services in primary care programs positively impacted health outcomes among the mentally ill in developing countries?

Objective. The World Health Organization (WHO) estimates that nearly 450 million people suffer from a mental disorder in the world. Developing countries do not have the health system structure in place to support the demand of mental health services. This study will conduct a review of mental health integration in primary care research that is carried out in low-income countries identified as such from the World Bank economic analysis. The research follows the standard of care that WHO has labeled appropriate in treatment of mental health populations. Methods. This study will use the WHO 10 principles of mental health integration into primary care as the global health standard of care for mental health. Low-income countries that used these principles in their national programs will be analyzed for effectiveness of mental health integration in primary care. Results. This study showed that mental health service integration in primary care did have an effect on health outcomes of low-income countries. However, information did not lead to significant quantitative results that determined how positive the effect was. Conclusion. More ethnographic research is needed in low-income countries to truly assess how effective the program is in integrating with the health system currently in place.^ ^

PREPAID MENTAL HEALTH SERVICES: A NATIONAL PERSPECTIVE

The purpose of this 1982 national survey of all operational prepaid health plans, or PHPs (including health maintenance organizations), was to provide information on the current coverage of PHP mental health and substance abuse services, benefits and service provision, general and mental health organization characteristics, mental health service costs, and physical and mental health service utilization.^ Two survey instruments were designed, pretested and distributed to all operational PHPs throughout the United States. A total of 237 PHPs were surveyed, of which 205 (86.50 percent) completed and returned both questionnaires.^ One result of the rapid growth in the PHP field over the past ten years has been the expansion in both the number of PHPs as well as the organizational characteristics of these PHPs. However, little attention in the research literature has been given to the application of empirical results to the PHP arrangements. This project has attempted to contribute to current knowledge regarding prepaid mental health services from a national perspective, and explore, on a preliminary descriptive basis, the variety of potential service delivery arrangements for physical and mental health services (total services) and for mental health services.^ The study emphasized that PHPs must continue to monitor the costs and utilization of mental health services, particularly in light of the apparent elimination of data collection and statistical summary responsibilities within the federal government regarding PHP activities as well as the proposed legislation to eliminate mandated mental health and substance abuse services from basic health plan benefits for federally qualified PHPs. ^

Systematic review of current trends of cardiovascular disease (CVD) and association between health insurance coverage and CVD mortality among women aged 60--65 in Texas in 2000--2011

Cardiovascular disease (CVD) is highly preventable, yet it is a leading cause of death among women in Texas. The primary goals of this research were to examine past and current trends of CVD, as well as identify whether there is an association between the insurance coverage and mortality from CVD among women aged 60–65 in Texas between 2000 and 2011. ^ The systematic review of the research is based on the guidelines and recommendations set by the Centre for Reviews and Dissemination for conducting reviews in health care. Over 47 citations of peer-reviewed articles from Ovid MEDLINE and PubMed databases and five websites were identified, of which 7 studies met inclusion criteria for the first systematic review to examine the trends of CVD in Texas. Ten citations of peer-reviewed articles from Ovid MEDLINE and PubMed databases and five web sites were reviewed for the second systematic review (to study the association between insurance coverage and cardiovascular health among Texas women 60–64 years of age), of which 3 studies met inclusion criteria and were included in the research. The results of the study highlighted key gaps in the existing literature and important areas for the further research, as well as determined directions for future public health CVD prevention programs in Texas. ^ Based on the conducted research, the major determinants of premature mortality among women attributed to cardiovascular disease are based on individual level characteristics, more specifically sex, age, race/ethnicity, and education. The results indicate that African American and non-Hispanic white women are more likely to have higher CVD mortality rates than Hispanic women due to higher prevalence of cardiac risk factors. The data also shows higher levels of mortality from CVD in the southeastern United States, with Texas ranking as the third state with the highest prevalence of CVD among women. According to the Texas Department of State Health Services, there are approximately 56,000 deaths caused by CVD annually in Texas, which represents about one death every ten minutes. Coronary artery disease and stroke were the causes of 31.2 percent of all female deaths in Texas in 2009, meaning that approximately 68 women die from any form of cardiac disease in Texas each day. ^ The data of the reviewed studies indicate that women' lack of health insurance was significantly associated with a higher prevalence of cardiovascular disease. The uninsured women were more likely to be unaware of their risk factors and more likely to have undiagnosed diabetes—a co-morbidity factor of CVD. One of the studies also reports strong correlation between state rates of uninsured and lower rates of preventive care. Given these strong correlations, those who were chronically uninsured were at a higher risk of mortality than the insured, due to prolonged periods of time without basic access to preventive and medical care. ^ Suggested recommendations to decrease CVD mortality rates in Texas are consistent with the existing literature and include state policy development that addresses elimination of health disparities, consideration of potential benefits of universal health coverage by the legislative policymakers, and maintenance of solid partnerships between public health agencies and hospitals to educate on, diagnose, and treat CVD among the female population in Texas. ^

Health promotion attitudes and practices of Texas nurse practitioners

The purpose of this descriptive cross-sectional survey was to examine the health promotion attitudes and practices of Texas nurse practitioners and to evaluate the applicability of the Theory of Reasoned Action and the Theory of Planned Behavior as a theoretical model to guide nurse practitioner health promotion research. A questionnaire developed to elicit responses regarding demographic information, practice characteristics, behavior, behavior intention, attitudes toward health promotion, subjective norm and perceived behavioral control for health promotion practices was mailed to the home address of 727 Texas nurse practitioners. The majority of the 442 respondents reported positive attitudes toward health promotion. Texas nurse practitioners provide health promotion for more than 50% of their patients. Significant barriers to the provision of health promotion cited by Texas nurse practitioners were lack of time, lack of reimbursement and lack of patient desire to change behavior. The findings of this study support the use of the Theory of Reasoned Action and the Theory of Planned Behavior in nurse practitioner research. ^

Environmental tobacco smoke exposure, respiratory and cardiovascular health in restaurant and bar workers in Mexico

Environmental tobacco smoke (ETS) is a well established health hazard, being causally associated to lung cancer and cardiovascular disease. ETS regulations have been developed worldwide to reduce or eliminate exposure in most public places. Restaurants and bars constitute an exception. Restaurants and bar workers experience the highest ETS exposure levels across several occupations, with correspondingly increased health risks. In Mexico, previous exposure assessment in restaurants and bars showed concentrations in bars and restaurants to be the highest across different public and workplaces. Recently, Mexico developed at the federal level the General Law for Tobacco Control restricting indoors smoking to separated areas. AT the local level Mexico City developed the Law for the Protection of Non-smokers Health, completely banning smoking in restaurants and bars. Studies to assess ETS exposure in restaurants and bars, along with potential health effects were required to evaluate the impact of these legislative changes and to set a baseline measurement for future evaluations.^ A large cross-sectional study conducted in restaurants and bars from four Mexican cities was conducted from July to October 2008, to evaluate the following aims: Aim 1) Explore the potential impact of the Mexico City ban on ETS concentrations through comparison of Mexico City with other cities. Aim 2). Explore the association between ETS exposure, respiratory function indicators and respiratory symptoms. Aim 3). Explore the association between ETS exposure and blood pressure and heart rate.^ Three cities with no smoking ban were selected: Colima (11.5% smoking prevalence), Cuernavaca (21.5% smoking prevalence) and Toluca (27.8% smoking prevalence). Mexico City (27.9% smoking prevalence), the only city with a ban at the time of the study, was also selected. Restaurants and bars were randomly selected from municipal records. A goal of 26 restaurants and 26 bars per city was set, 50% of them under 100 m2. Each establishment was visited during the highest occupancy shift, and managers and workers answered to a questionnaire. Vapor-phase nicotine was measured using passive monitors, that were activated at the beginning and deactivated at the end of the shift. Also, workers participated at the beginning and end of the shift in a short physical evaluation, comprising the measurement of Forced Expiratory Volume in the first second (FEV1) and Peak Expiratory Flow (PEF), as well as blood pressure and heart rate.^ A total of 371 establishments were invited, 219 agreed to participate for a 60.1% participation rate. In them, 828 workers were invited, 633 agreed to participate for a 76% participation rate. Mexico City had at least 4 times less nicotine compared to any of the other cities. Differences between Mexico City and other cities were not explained by establishment characteristics, such as ventilation or air extraction. However, differences between cities disappeared when ban mechanisms, such as policy towards costumer's smoking, were considered in the models. An association between ETS exposure and respiratory symptoms (cough OR=1.27, 95%CI=1.04, 1.55) and respiratory illness (asthma OR=1.97, 95%CI=1.20, 3.24; respiratory illness OR=1.79, 95%CI=1.10, 2.94) was observed. No association between ETS and phlegm, wheezing or respiratory infections was observed. No association between ETS and any of the spirometric indicators was observed. An association between ETS exposure and increased systolic and diastolic blood pressure at the end of the shift was observed among non-smokers (systolic blood pressure beta=1.51, 95%CI=0.44, 2.58; diastolic blood pressure beta=1.50, 95%CI=0.72, 2.28). The opposite effect was observed in heavy smokers, were increased ETS exposure was associated with lower blood pressure at the end of the shift (systolic blood pressure beta=1.90, 95%CI=-3.57, -0.23; diastolic blood pressure beta=-1.46, 95%CI=-2.72, -0.02). No association in light smokers was observed. No association for heart rate was observed. ^ Results from this dissertation suggest Mexico City's smoking ban has had a larger impact on ETS exposure. Ventilation or air extraction, mechanisms of ETS control suggested frequently by tobacco companies to avoid smoking bans were not associated with ETS exposure. This dissertation suggests ETS exposure could be linked to changes in blood pressure and to increased respiratory symptoms. Evidence derived from this dissertation points to the potential negative health effects of ETS exposure in restaurants and bars, and provides support for the development of total smoking bans in this economic sector. ^

A systematic review examining the relationship between oral health care practices and the oral lesions commonly associated with HIV/AIDS, and the implications for people living in developing countries

Oral lesions, which may be bacterial, fungal or viral in nature may be characteristic of HIV/ AIDS, and have been observed on the oral mucosa as early signs of underlying disease. Some studies have suggested that there may be a correlation between poor oral hygiene, and the oral lesions seen among people living with HIV/AIDS.^ The objective of this study was to assess the nature of the relationship between oral health care practices, and the occurrence of oral lesions commonly seen in association with HIV/AIDS. A systematic review of the literature was conducted, and the databases searched were Medline and PubMed. Concepts that made up the search were oral hygiene promotion, HIV/AIDS and oral health care. Out of the 410 items identified through the search, only 11 met the inclusion criteria.^ The use of 0.12%–2% chlorhexidine gluconate, was found to be effective in reducing oral Candida counts in some studies, while other studies did not find such an association. However, 0.12%–2% chlorhexidine gluconate was consistently found to be effective in the management of periodontal lesions in people infected with HIV/AIDS. ^ Dental procedures such as treatment and filling of dental cavities, scaling and polishing, and use of fluoridated tooth paste were also found to be effective in the management of oral lesions seen in association with HIV/AIDS.^ The overall findings from the studies reviewed, suggest that effective oral health care may be necessary to reduce the morbidity, and mortality associated with the oral lesions seen among people living with HIV/AIDS. However, better designed studies with larger sample sizes need to be developed in order to ascertain the effectiveness of routine oral hygiene, and health care practices among people living with HIV/AIDS.^
