The multiple location time weighted index: Using patient activity spaces to calculate primary care service areas

Geographic health planning analyses, such as service area calculations, are hampered by a lack of patient-specific geographic data. Using the limited patient address information in patient management systems, planners analyze patient origin based on home address. But activity space research done sparingly in public health and extensively in non-health related arenas uses multiple addresses per person when analyzing accessibility. Also, health care access research has shown that there are many non-geographic factors that influence choice of provider. Most planning methods, however, overlook non-geographic factors influencing choice of provider, and the limited data mean the analyses can only be related to home address. This research attempted to determine to what extent geography plays a part in patient choice of provider and to determine if activity space data can be used to calculate service areas for primary care providers. ^ During Spring 2008, a convenience sample of 384 patients of a locally-funded Community Health Center in Houston, Texas, completed a survey that asked about what factors are important when he or she selects a health care provider. A subset of this group (336) also completed an activity space log that captured location and time data on the places where the patient regularly goes. ^ Survey results indicate that for this patient population, geography plays a role in their choice of health care provider, but it is not the most important reason for choosing a provider. Other factors for choosing a health care provider such as the provider offering "free or low cost visits", meeting "all of the patient's health care needs", and seeing "the patient quickly" were all ranked higher than geographic reasons. ^ Analysis of the patient activity locations shows that activity spaces can be used to create service areas for a single primary care provider. Weighted activity-space-based service areas have the potential to include more patients in the service area since more than one location per patient is used. Further analysis of the logs shows that a reduced set of locations by time and type could be used for this methodology, facilitating ongoing data collection for activity-space-based planning efforts. ^

A qualitative and quantitative assessment of cancer patients' perceptions of barriers to treatment

This study examined barriers that cancer patients experience in obtaining treatment. The principal aim of the study was to conduct a comprehensive quantitative and qualitative assessment of barriers to cancer treatment for Texas cancer patients. The three specific aims of the study were to: (1) conduct a review and critique of published and unpublished research on barriers to cancer treatment; (2) conduct focus groups for the qualitative assessment of cancer patients' perceived barriers to cancer treatment; and (3) survey a representative sample of cancer patients regarding perceived barriers to treatment. The study was guided by the Aday and Andersen access framework of predisposing, enabling, and need determinants of care-seeking.^ To address the first specific aim, a total of 732 abstracts were examined, from which 154 articles were selected for review. Of these 154 articles, 57 that related directly to research on barriers to cancer treatment were chosen for subsequent analysis. Criteria were applied to each article to evaluate the strength of the study design, sampling and measurement procedures. The major barriers that were consistently documented to influence whether or not cancer patients sought or continued required treatment included problems with communication between the patient and provider, lack of information on side effects, the cost of treatment and associated difficulties in obtaining and maintaining insurance coverage, and the absence of formal and informal networks of social support. Access barriers were generally greater for older, minority women, and patients of lower socioeconomic status.^ To address the second specific aim, a total of eight focus groups (n = 44) were conducted across the State of Texas with cancer patients identified by the Texas Community Oncology Network, American Cancer Society, and community health centers. One important finding was that cost is the greatest hurdle that patients face. Another finding was that with the health care/insurance crisis, an increasing number of physicians are working with their patients to develop individually-tailored payment plans. For people in rural areas, travel to treatment sites is a major barrier due to the travel costs as well as work time forfeited by patients and their family members. A third major finding was the patients' family and church play important roles in providing social and emotional support for cancer patients.^ To address the third aim, a total of 910 cancer patients were surveyed during October and November, 1993. Approximately 65% of the cancer patients responded to the survey. The findings showed that the major barriers to treatment included costs of medications and diagnostic tests, transportation, lack of social support, problems understanding the written information regarding their disease as well as losing coverage or having higher premiums or copayments once they were diagnosed (particularly among blacks).^ Significant differences in reported barriers were found between racial groups. The minority respondents (i.e., blacks and Hispanics) tended to experience more barriers to treatment compared to the white respondents. More specifically, Hispanics were more likely to report transportation as a barrier to treatment than both white and blacks. Future research is needed to better understand the problems that minority cancer patients experience in receiving treatment. (Abstract shortened by UMI.) ^

DISCHARGE PLANNING: A PROCESS MODEL

As the requirements for health care hospitalization have become more demanding, so has the discharge planning process become a more important part of the health services system. A thorough understanding of hospital discharge planning can, then, contribute to our understanding of the health services system. This study involved the development of a process model of discharge planning from hospitals. Model building involved the identification of factors used by discharge planners to develop aftercare plans, and the specification of the roles of these factors in the development of the discharge plan. The factors in the model were concatenated in 16 discrete decision sequences, each of which produced an aftercare plan.^ The sample for this study comprised 407 inpatients admitted to the M. D. Anderson Hospital and Tumor Institution at Houston, Texas, who were discharged to any site within Texas during a 15 day period. Allogeneic bone marrow donors were excluded from the sample. The factors considered in the development of discharge plans were recorded by discharge planners and were used to develop the model. Data analysis consisted of sorting the discharge plans using the plan development factors until for some combination and sequence of factors all patients were discharged to a single site. The arrangement of factors that led to that aftercare plan became a decision sequence in the model.^ The model constructs the same discharge plans as those developed by hospital staff for every patient in the study. Tests of the validity of the model should be extended to other patients at the MDAH, to other cancer hospitals, and to other inpatient services. Revisions of the model based on these tests should be of value in the management of discharge planning services and in the design and development of comprehensive community health services.^

Pilot study assessment of indoor air quality in two dental settings: Particulate matter and volatile organic compounds

Objective: To assess the indoor environment of two different types of dental practices regarding VOCs, PM2.5, and ultrafine particulate concentrations and examine the relationship between specific dental activities and contaminant levels. Method: The indoor environments of two selected dental settings (private practice and community health center) will were assessed in regards to VOCs, PM 2.5, and ultrafine particulate concentrations, as well as other indoor air quality parameters (CO2, CO, temperature, and relative humidity). The sampling duration was four working days for each dental practice. Continuous monitoring and integrated sampling methods were used and number of occupants, frequency, type, and duration of dental procedures or activities recorded. Measurements were compared to indoor air quality standards and guidelines. Results: The private practice had higher CO2, CO, and most VOC concentrations than the community health center, but the community health center had higher PM2.5 and ultrafine PM concentrations. Concentrations of p-dichlorobenzene and PM2.5 exceeded some guidelines. Outdoor concentrations greatly influenced the indoor concentration. There were no significant differences in contaminant levels between the operatory and general area. Indoor concentrations during the working period were not always consistently higher than during the nonworking period. Peaks in particulate matter concentration occurred during root canal and composite procedures.^

Assessing the relationship between obesity and type II diabetes among South Asian Indians in Houston A population based study

Objective: My study aimed at determining the association between obesity and diabetes prevalence in South Asian Indian immigrants in Houston, Texas. To also compare the prevalence odds of diabetes given obesity, using WHO-BMI criteria and recommended Asian ethnic-specific BMI criteria for obesity, as well as using WHO-standard waist circumference criteria and ethnic-specific criteria for abdominal obesity, across gender and age, in this population. ^ Methods: My study was a secondary data analysis based on a cross-sectional study carried out on adult South Asian Indians who attended a local community health fair in Houston, in 2007. They recruited 213 voluntary, eligible, South Asian Indian participants aged between 18 to 79 years. Self reported history of Diabetes was obtained and height, weight, waist and hip circumference were measured. I classified BMI based on WHO-standard and ethnic-specific criteria, according to gender and age groups of 18–35 years, 36–64 years and 65 years and over. Waist circumference was also classified based on WHO-standard NCEP criteria and currently recommended ethnic-specific IDF criteria and analysis was done stratifying by gender and age groups. ^ Results: The prevalence of diabetes in this population was 14.6%, significantly higher in older age groups (25.8%) and males (19.2%). The prevalence of DM was statistically similar in individuals who were overweight/obese compared to those not overweight/obese, however in overweight/obese individuals, there was a statistically significant difference in the prevalence of DM between WHO and ethnic-specific criteria for both BMI and waist circumference. In older adults and in males, ethnic-specific criteria identified significantly more as overweight/obese compared to WHO-standard criteria. ^ Conclusions: Ethnic-specific criteria for both BMI and waist circumference give a better estimate for obesity in this South Asian Indian population. Diabetes is highly prevalent in migrant South Asian Indians even at low BMI or waist circumference levels and significantly more in males and older age groups, hence adequate awareness should be created for early prevention and intervention.^

Evaluation of CHIP perinatal program outcomes in Harris County, Texas

This study compared initial year trends in prenatal care and birth outcomes of women enrolled in the Texas Children's Health Insurance Program (CHIP) Perinatal program to trends in Medicaid program women. The study utilized claims data from Community Health Choice (CHC), a health plan in Harris County, Texas that provides coverage to both populations. Quarterly data was analyzed and compared for the first two years of the CHIP Perinatal program (2007-2008) to determine if outcome trends for the CHIP program improved over the outcome trends seen with those enrolled in Medicaid. Study findings indicate an increase in the quarterly prenatal care utilization for the CHIP Perinatal population from 2007 to 2008 and the associated birth weights of babies delivered also had marginal improvements during the same timeframe. Enrollees in Medicaid continued to have overall better outcomes than those enrolled within the CHIP Perinatal program. However, the study showed that the rate of improvement in both prenatal care utilization and birth outcomes were greater for the CHIP Perinatal enrollees than those enrolled in Medicaid. ^ The majority of these improvements were significant when comparing each coverage program and from year to year. Lastly, the study showed that there was a correlation between prenatal care utilization and birth outcomes. However, further analysis of the data could not conclusively indicate that access to prenatal care services provided by the CHIP Perinatal program contributed to the increases observed in utilization and birth outcomes for the study's sample population.^

The Hospital Study of the City of Houston and Harris County

In 1941 the Texas Legislature appropriated $500,000 to the Board of Regents of the University of Texas to establish a cancer research hospital. The M. D. Anderson Foundation offered to match the appropriation with a grant of an equal sum and to provide a permanent site in Houston. In August, 1942 the Board of Regent of the University and the Trustees of the Foundation signed an agreement to embark on this project. This institution was to be the first one in the medical center, which was incorporated in October, 1945. The Board of Trustees of the Texas Medical Center commissioned a hospital survey to: - Define the needed hospital facilities in the area - Outline an integrated program to meet these needs - Define the facilities to be constructed - Prepare general recommendations for efficient progress The Hospital Study included information about population, hospitals, and other health care and education facilities in Houston and Harris County at that time. It included projected health care needs for future populations, education needs, and facility needs. It also included detailed information on needs for chronic illnesses, a school of public health, and nursing education. This study provides valuable information about the general population and the state of medicine in Houston and Harris County in the 1940s. It gives a unique perspective on the anticipated future as civic leaders looked forward in building the city and region. This document is critical to an understanding of the Texas Medical Center, Houston and medicine as they are today. SECTIONS INCLUDE: Abstract The Abstract was a summary of the 400 page document including general information about the survey area, community medical assets, and current and projected medical needs which the Texas Medical Center should meet. The 123 recommendations were both general (e.g., 12. “That in future planning, the present auxiliary department of the larger hospitals be considered inadequate to carry an added teaching research program of any sizable scope.”) and specific (e.g., 22. That 14.3% of the total acute bed requirement be allotted for obstetric care, reflecting a bed requirement of 522 by 1950, increasing to 1,173 by 1970.”) Section I: Survey Area This section basically addressed the first objective of the survey: “define the needed hospital facilities in the area.” Based on the admission statistics of hospitals, Harris County was included in the survey, with the recognition that growth from out-lying regional areas could occur. Population characteristics and vital statistics were included, with future trends discussed. Each of the hospitals in the area and government and private health organizations, such as the City-County Welfare Board, were documented. Statistics on the facilities use and capacity were given. Eighteen recommendations and observations on the survey area were given. Section II: Community Program This section basically addressed the second objective of the survey: “outline an integrated program to meet these needs.” The information from the Survey Area section formed the basis of the plans for development of the Texas Medical Center. In this section, specific needs, such as what medical specialties were needed, the location and general organization of a medical center, and the academic aspects were outlined. Seventy-four recommendations for these plans were provided. Section III: The Texas Medical Center The third and fourth objectives are addressed. The specific facilities were listed and recommendations were made. Section IV: Special Studies: Chronic Illness The five leading causes of death (heart disease, cancer, “apoplexy”, nephritis, and tuberculosis) were identified and statistics for morbidity and mortality provided. Diagnostic, prevention and care needs were discussed. Recommendations on facilities and other solutions were made. Section IV: Special Studies: School of Public Health An overview of the state of schools of public health in the US was provided. Information on the direction and need of this special school was also provided. Recommendations on development and organization of the proposed school were made. Section IV: Special Studies: Needs and Education Facilities for Nurses Nursing education was connected with hospitals, but the changes to academic nursing programs were discussed. The needs for well-trained nurses in an expanded medical environment were anticipated to result in significant increased demands of these professionals. An overview of the current situation in the survey area and recommendations were provided. Appendix A Maps, tables and charts provide background and statistical information for the previous sections. Appendix B Detailed census data for specific areas of the survey area in the report were included. Sketches of each of the fifteen hospitals and five other health institutions showed historical information, accreditations, staff, available facilities (beds, x-ray, etc.), academic capabilities and financial information.

Texas Medical Center --- Its Origins

This document details the people and institutions who were instrumental in the establishment and development of the Texas Medical Center (TMC). Biographical information about the founders, role the M. D. Anderson Foundation, and opening of the main institutions in the early 1950s is detailed. A copy of a speech given in 1958 by W. B. Bates, one of the trustees of the M. D. Anderson Foundation, on the history and development of the TMC is significant because he was one of the founders of the TMC. This document was commissioned by the Houston Chamber of Commerce in 1971 as the Texas Medical Center began a new phase of expansion with the pending addition of The University of Texas Medical School at Houston. It includes information about each of the 21 institutions which comprised the TMC at that time.

Distributed System for Cognitive Stimulation Over Interactive TV.

Descripción y evaluación de sistema de estimulación cognitiva a través de la TDT orientada a personas con enfermedad de Parkinson, con supervisión por parte de sus terapeutas de forma remota. Abstract: This paper details the full design, implementation, and validation of an e-health service in order to improve the community health care services for patients with cognitive disorders. Specifically, the new service allows Parkinson’s disease patients benefit from the possibility of doing cognitive stimulation therapy (CST) at home by using a familiar device such as a TV set. Its use instead of a PC could be a major advantage for some patients whose lack of familiarity with the use of a PC means that they can do therapy only in the presence of a therapist. For these patients this solution could bring about a great improvement in their autonomy. At the same time, this service provides therapists with the ability to conduct follow-up of therapy sessions via the web,benefiting from greater and easier control of the therapy exercises performed by patients and allowing them to customize new exercises in accordance with the particular needs of each patient. As a result, this kind of CST is considered to be a complement of other therapies oriented to the Parkinson patients. Furthermore, with small changes, the system could be useful for patients with a different cognitive disease such as Alzheimer’s or mild cognitive impairment.

O agente comunitário e o usuário de álcool: discursos sobre a concepção e a assistência na Atenção Básica

Estima-se que 52% da população mundial faz uso de álcool, sendo a droga mais consumida no mundo. Ao usuário, o álcool torna-se prejudicial devido às consequências nos níveis biológicos, sociais e funcionais. Assim, a redução do uso abusivo da substância é um dos objetivos da Organização Mundial de Saúde (OMS) e uma das prioridades na agenda de saúde pública mundial. No Brasil, a Política do Ministério da Saúde para a Atenção Integral aos Usuários de Álcool e Outras Drogas teve como objetivo a criação de uma rede de atenção integral a eles - a RAPS (Rede de Atenção Psicossocial). A RAPS é considerada um grande avanço da Reforma Psiquiátrica, já que integra os diversos pontos de atenção disponíveis no Sistema Único de Saúde (SUS). Um dos pontos da RAPS é a Atenção Básica (AB), que através da atuação das equipes da Estratégia Saúde da Família (ESF) tem a possibilidade de monitoração, prevenção do uso e colaboração na reinserção social dos usuários de álcool e outras drogas devido à proximidade e criação de vínculo entre o serviço e usuário. Para que o vínculo seja estabelecido o Agente Comunitário de Saúde (ACS) é a peça fundamental, visto que conhece a comunidade e reconhece suas necessidades, além de ser a figura que medeia as relações entre a equipe de saúde e os usuários. Assim sendo, o objetivo deste estudo foi descrever e analisar o discurso de ACS sobre o uso de álcool e a assistência prestada na AB. Trata-se de um estudo qualitativo de teor descritivo, cuja pesquisa ocorreu em cinco municípios da região central do Estado de Santa Catarina. Foram realizadas entrevistas semiestruturadas, analisadas através do método da Análise de Conteúdo. A análise das entrevistas resultou na formulação de duas categorias e quatro subcategorias empíricas. Os resultados evidenciaram que os ACS percebem o consumo de álcool como inerente a população em virtude da cultura caracterizada pelo consumo habitual e festivo da droga. Eles percebem que o uso do álcool torna-se um problema quanto à definição social atribuída pela comunidade, ressaltando as consequências para a família e outras perdas vivenciadas pelos usuários com base nas repercussões sociais. Quanto à assistência prestada por eles aos usuários de álcool, os resultados indicaram uma prática desprovida de instrumentos ou habilidades para a abordagem adequada do uso, evidenciando uma prática infundada pelos ACS. A prática está pautada também nas crenças em relação aos usuários de álcool, que estão muito ligadas aos estigmas relacionados a estes usuários em geral e não em evidências científicas. Conclui-se que a partir do conhecimento das percepções e práticas deste profissional, é possível direcionar ações que potencialize a prática dos ACS, já que são profissionais com grandes possibilidades de atuação diante da prevenção e tratamento do abuso de álcool e reabilitação social do usuário

O idoso e sua participação - aspectos da vida urbana componentes da cidade amiga do idoso

Esta investigação teve por objetivo analisar a participação de idosos em direção à promoção da saúde considerando a articulação com oito aspectos da vida urbana do projeto cidade amiga do idoso (espaços abertos e prédios, transporte, moradia, participação social, respeito e inclusão social, participação cívica e emprego, comunicação e informação, e apoio comunitário e serviços de saúde) do bairro Vila Tibério, município de Ribeirão Preto, estado de São Paulo, Brasil. Trata-se de pesquisa descritiva de abordagem qualitativa sustentada pelos conceitos e princípios da promoção da saúde, a partir da perspectiva da participação social e do estabelecimento de ambientes saudáveis, motivo do alinhamento com os aspectos da vida urbana do Projeto Cidade Amiga do Idoso. A pesquisa atendeu aos preceitos éticos, sendo sua realização aprovada por Comitê de Ética em Pesquisa. A captação do empírico se deu por meio da realização de grupos focais com base no Protocolo de Vancouver, desenvolvido pelo Government of British Columbia, somando 32 idosos e 6 representantes de prestadores de serviços em 5 grupos focais. Adicionalmente, foi aplicado instrumento de avaliação funcional para verificar condição de independência ou dependência dos 32 idosos, sendo feita avaliação qualitativa da capacidade autorreferida pelos idosos, segundo a escala utilizada. Realizou-se análise de conteúdo na vertente temática para o material dos grupos, com a identificação de três temas: território: lugar de vida e cidadania, formação de redes de suporte social ao idoso e participação dos idosos na vida do bairro. A violência, o abandono presentes no território, em especial nos espaços coletivos, trazem preocupação e medo aos idosos, pois dificultam a livre circulação no território. Por outro lado, há no bairro certa tradição e possibilidade de serem construídas relações de amizade e apoio, que permitem ao idoso sentir-se acolhido, sendo enfatizado que as relações de amizade e mesmo as institucionalizadas, como por exemplo, o trabalho dos agentes comunitários de saúde, são necessárias às relações de convivência e sustentação na vida dos idosos. É trazida a importância dos jornais do bairro e de seu papel como elemento constitutivo da rede apoio na área de comunicação e informação dentro do território. A vinculação ao mundo do trabalho, com atividades remuneradas, ainda é uma forma que os idosos encontram de se manterem próximos aos amigos e participantes da vida em comunidade. Há dificuldade em ampliar a participação dos idosos por diferentes motivos que vão desde a dificuldade de mobilidade dentro do bairro, acesso à informação sobre as atividades disponíveis, ausência de canais mais ágeis de comunicação, baixa adesão aos processos de participação social no campo da saúde e assistência social, trabalho dos idosos como cuidadores de outros idosos familiares ou de netos. Situações que dificultam maior adesão aos processos de participação social, embora seja assinalada a importância destes processos para a melhoria do bairro. O conjunto dos resultados aponta que os idosos apresentam muitas dificuldades para ampliar sua participação nos processos coletivos no bairro, que por vezes se mostra hostil em suas condições a este grupo. Por outro lado se fazem presentes potencialidades, nas brechas e sugestões que indicam a possibilidade para se situarem no processo de construção da Promoção da Saúde no território em que estão inseridos, utilizando de suas características, perfis de vida e atuação para agir com autonomia e constituírem-se como protagonistas dos processos e de ações no território. Com a ciência dos limites, credita-se a esta investigação a possibilidade de que os elementos aqui discutidos possam oferecer subsídios para que as políticas voltadas ao envelhecimento saudável nos âmbitos da saúde, segurança, educação, assistência social, dentre outras possam se repensadas ou reestruturadas

Salud comunitaria y acción social en el control epidemiológico del tracoma infantil, España (1932-1939)

En el contexto de la endemia tracomatosa que afectó a diversas regiones españolas hasta la década de 1960, se analizan los determinantes epidemiológicos del tracoma infantil y su abordaje desde el modelo de asistencia preventiva que encerraba el concepto de salud comunitaria que se perfiló en el período de entreguerras. La detección precoz de casos, unida a actividades preventivas, educativas, terapéuticas y de inspección, como las que llevaron a cabo las enfermeras visitadoras, contribuyeron al control de la enfermedad. Los resultados reafirman la validez de las estrategias de intervención horizontal de mejora de las condiciones higiénicas y de los factores medioambientales que explicaban la prevalencia del tracoma.
