Cultural models of healing and health: An ethnography of professional nurses and healers

Cultural models of the domains healing and health are important in how people understand health and their behavior regarding it. The biomedicine model has been predominant in Western society. Recent popularity of holistic health and alternative healing modalities contrasts with the biomedical model and the assumptions upon which that model has been practiced. The holistic health movement characterizes an effort by health care providers and others such as nurses to expand the biomedical model and has often incorporated alternative modalities. This research described and compared the cultural models of healing of professional nurses and alternative healers. A group of nursing faculty who promote a holistic model were compared to a group of healers using healing touch. Ethnographic methods of participant observation, free listing and pile sort were used. Theoretical sampling in the free listings reached saturation at 18 in the group of nurses and 21 in the group of healers. Categories consistent for both groups emerged from the data. These were: physical, mental, attitude, relationships, spiritual, self management, and health seeking including biomedical and alternative resources. The healers had little differentiation between the concepts health and healing. The nurses, however, had more elements in self management for health and in health seeking for healing. This reflects the nurse's role in facilitating the shift in locus of responsibility between health and healing. The healers provided more specific information regarding alternative resources. The healer's conceptualization of health was embedded in a spiritual belief system and contrasted dramatically with that of biomedicine. The healer's models also contrasted with holistic health in the areas of holism, locus of responsibility, and dealing with uncertainty. The similarity between the groups and their dissimilarity to biomedicine suggest a larger cultural shift in beliefs regarding health care. ^

Review: "Health service frameworks for small rural and remote communities: issues and options" by J. Humphreys, S. Mathews-Cowey, F. Rolley 1996

This monograph is a welcome investigation of current issues in rural health service delivery in smaller communities. The underlying assumption is that existing health service frameworks for rural and remote communities with populations of less than 230 are simply- not appropriate for their needs. With this in mind, the authors identify the strengths and weaknesses of frameworks presently utilised, and offer viable alternatives. They have made information accessible to those who wish to improve the delivery of rural health care, and have provided a catalyst for further research and dialogue on rural health issues...

Development and application of a predictive model of freshwater fish assemblage composition to evaluate river health in eastern Australia

Multivariate predictive models are widely used tools for assessment of aquatic ecosystem health and models have been successfully developed for the prediction and assessment of aquatic macroinvertebrates, diatoms, local stream habitat features and fish. We evaluated the ability of a modelling method based on the River InVertebrate Prediction and Classification System (RIVPACS) to accurately predict freshwater fish assemblage composition and assess aquatic ecosystem health in rivers and streams of south-eastern Queensland, Australia. The predictive model was developed, validated and tested in a region of comparatively high environmental variability due to the unpredictable nature of rainfall and river discharge. The model was concluded to provide sufficiently accurate and precise predictions of species composition and was sensitive enough to distinguish test sites impacted by several common types of human disturbance (particularly impacts associated with catchment land use and associated local riparian, in-stream habitat and water quality degradation). The total number of fish species available for prediction was low in comparison to similar applications of multivariate predictive models based on other indicator groups, yet the accuracy and precision of our model was comparable to outcomes from such studies. In addition, our model developed for sites sampled on one occasion and in one season only (winter), was able to accurately predict fish assemblage composition at sites sampled during other seasons and years, provided that they were not subject to unusually extreme environmental conditions (e.g. extended periods of low flow that restricted fish movement or resulted in habitat desiccation and local fish extinctions).

What are pregnant women told about models of maternity care in Australia? A retrospective study of women's reports

Objective To describe women’s reports of the model of care options General Practitioners (GPs) discussed with them at the first pregnancy consultation and women’s self-reported role in decisionmaking about model of care. Methods Women who had recently given birth responded to survey items about the models of care GPs discussed, their role in final decision-making, and socio-demographic, obstetric history, and early pregnancy characteristics. Results The proportion of women with whom each model of care was discussed varied between 8.2% (for private midwifery care with home birth) and 64.4% (GP shared care). Only 7.7% of women reported that all seven models were discussed. Exclusive discussion about private obstetric care and about all public models was common, and women’s health insurance status was the strongest predictor of the presence of discussions about each model. Most women (82.6%) reported active involvement in final decision-making about model of care. Conclusion Although most women report involvement in maternity model of care decisions, they remain largely uninformed about the breadth of available model of care options. Practical implications Strategies that facilitate women’s access to information on the differentiating features and outcomes for all models of care should be prioritized to better ensure equitable and quality decisions.

Specialist versus generic models of psychiatry training and service provision for people with intellectual disabilities

Background  Models of service provision and professional training differ between countries. This study aims to investigate a specialist intellectual disabilities model and a generic mental health model, specifically comparing psychiatrists’ knowledge and competencies, and service quality and accessibility in meeting the mental health needs of people with intellectual disabilities. Method  Data were collected from consultant and trainee psychiatrists within a specialist intellectual disabilities model (UK) and a generic mental health model (Australia). Results  The sample sizes were 294 (UK) and 205 (Australia). Statistically significant differences were found, with UK participants having positive views about the specialist intellectual disabilities service model they worked within, demonstrating flexible and accessible working practices and service provision, responsive to the range of mental health needs of the population with intellectual disabilities, and providing a wide range of treatments and supports. The UK participants were knowledgeable, well trained and confident in their work. They wanted to work with people with intellectual disabilities. In all of these areas, the converse was found from the Australian generic mental health service model. Conclusions  The specialist intellectual disabilities model of service provision and training has advantages over the generic mental health model.

Mixture models of nucleotide sequence evolution that account for heterogeneity in the substitution process across sites and across lineages

Molecular phylogenetic studies of homologous sequences of nucleotides often assume that the underlying evolutionary process was globally stationary, reversible, and homogeneous (SRH), and that a model of evolution with one or more site-specific and time-reversible rate matrices (e.g., the GTR rate matrix) is enough to accurately model the evolution of data over the whole tree. However, an increasing body of data suggests that evolution under these conditions is an exception, rather than the norm. To address this issue, several non-SRH models of molecular evolution have been proposed, but they either ignore heterogeneity in the substitution process across sites (HAS) or assume it can be modeled accurately using the distribution. As an alternative to these models of evolution, we introduce a family of mixture models that approximate HAS without the assumption of an underlying predefined statistical distribution. This family of mixture models is combined with non-SRH models of evolution that account for heterogeneity in the substitution process across lineages (HAL). We also present two algorithms for searching model space and identifying an optimal model of evolution that is less likely to over- or underparameterize the data. The performance of the two new algorithms was evaluated using alignments of nucleotides with 10 000 sites simulated under complex non-SRH conditions on a 25-tipped tree. The algorithms were found to be very successful, identifying the correct HAL model with a 75% success rate (the average success rate for assigning rate matrices to the tree's 48 edges was 99.25%) and, for the correct HAL model, identifying the correct HAS model with a 98% success rate. Finally, parameter estimates obtained under the correct HAL-HAS model were found to be accurate and precise. The merits of our new algorithms were illustrated with an analysis of 42 337 second codon sites extracted from a concatenation of 106 alignments of orthologous genes encoded by the nuclear genomes of Saccharomyces cerevisiae, S. paradoxus, S. mikatae, S. kudriavzevii, S. castellii, S. kluyveri, S. bayanus, and Candida albicans. Our results show that second codon sites in the ancestral genome of these species contained 49.1% invariable sites, 39.6% variable sites belonging to one rate category (V1), and 11.3% variable sites belonging to a second rate category (V2). The ancestral nucleotide content was found to differ markedly across these three sets of sites, and the evolutionary processes operating at the variable sites were found to be non-SRH and best modeled by a combination of eight edge-specific rate matrices (four for V1 and four for V2). The number of substitutions per site at the variable sites also differed markedly, with sites belonging to V1 evolving slower than those belonging to V2 along the lineages separating the seven species of Saccharomyces. Finally, sites belonging to V1 appeared to have ceased evolving along the lineages separating S. cerevisiae, S. paradoxus, S. mikatae, S. kudriavzevii, and S. bayanus, implying that they might have become so selectively constrained that they could be considered invariable sites in these species.

Allied health growth: What we do not measure we cannot manage

Background Data describing the Australian allied health workforce is inadequate and so insufficient for workforce planning. National health policy reform requires that health-care models take into account future workforce requirements, the distribution and work contexts of existing practitioners, training needs, workforce roles and scope of practice. Good information on this workforce is essential for managing services as demands increase, accountability of practitioners, measurement of outcomes and benchmarking against other jurisdictions. A comprehensive data set is essential to underpin policy and planning to meet future health workforce needs. Discussion Some data on allied health professions is managed by the Australian Health Practitioner Regulation Agency; however, there is limited information regarding several core allied health professions. A global registration and accreditation scheme recognizing all allied health professions might provide safeguards and credibility for professionals and their clients. Summary Arguments are presented about inconsistencies and voids in the available information about allied health services. Remedying these information deficits is essential to underpin policy and planning for future health workforce needs. We make the case for a comprehensive national data set based on a broad and inclusive sampling process across the allied health population.

O que sabe o agente comunitário de saúde ?

A partir da formalização do Programa de Agentes Comunitários de Saúde e do Programa Saúde da Família pelo Ministério da Saúde (anos 90), as discussões sobre a reorientação dos modelos assistenciais ganham destaque. O Programa Saúde da Família passa a ser visto por boa parte dos profissionais de saúde coletiva como um modelo capaz de imprimir mudanças não apenas na atenção em si como também na dinâmica dos processos. Ao propor a substituição das estratégias tradicionais, voltadas para a doença e centradas no hospital, a nova proposta voltase, entre outros aspectos, para a ação preventiva e para a promoção da saúde. Busca contemplar também a atenção às necessidades de saúde da população adscrita, a família e seu território, ações intersetoriais e tem na equipe multiprofissional pilar importante no cuidado. O Agente Comunitário de Saúde se apresenta como ator importante na possibilidade de mudança de modelo assistencial; atuando intensamente na produção do cuidado assim como na organização de tal assistência. Criam-se conflitos acerca da percepção de potencialidades e da possibilidade de interação entre os diversos aspectos envolvidos neste contexto. Este trabalho buscou investigar a percepção de Agentes Comunitários de Saúde do município de Petrópolis RJ acerca dos saberes envolvidos na sua prática. A estratégia metodológica utilizada para coleta de dados em campo foi a de entrevistas semi estruturadas. O corpo textual gerado pelas entrevistas foi analisado com base na teoria da Análise do Discurso. Este estudo concluiu que o saber do Agentes Comunitários de Saúde aponta para uma posição que vai além de ser ponte ou de fazer ponte. Argumenta que a potencialidade deste saber é a de ser como a linha de costura entre comunidade e as propostas de cuidado. Esta imagem indica que ao pertencer em algum momento a ambos tecidos, e ao fazer o movimento de pertencer ora ao tecido comunidade e hora ao tecido UBS, o ACS pode aproximar essas partes na busca da construção de algo mais unificado. Como em uma colcha de retalhos, onde cada tecido mantém suas características e padronagens iniciais, mas aos serem costurados, formam algo único, inteiro.

Tensões entre as concepções e as políticas públicas de Educação Profissional em Saúde de nível médio no Estado do Rio Grande do Sul

A presente tese parte das questões relativas às tensões políticas/organizativas ou de concepção, existentes historicamente entre a saúde e a educação, referentes à Educação Profissional em Saúde; busca responder até que ponto as políticas educacionais respondem às necessidades de formação dos trabalhadores técnicos da saúde no Estado do Rio Grande do Sul, como também de que forma a autonomia estadual repercute sobre as políticas de saúde e de educação na área da educação profissional em saúde, visto que o processo de descentralização se dá de forma distinta nestes dois campos. O objetivo geral do estudo foi apreender as tensões de natureza conceptual, política e legal, historicamente construídas, na relação entre as necessidades de formação técnica em saúde e as políticas educacionais, identificando implicações sobre a regulação da Educação Profissional em Saúde no Estado do Rio Grande do Sul. Esta tese sustenta-se no materialismo histórico como teoria e método. Parte das concepções marxianas sobre o trabalho constituído das relações sociais em diferentes épocas históricas, da educação formal como parte da totalidade dos processos sociais e do Estado como um complexo de relações que materializa o modo de produção capitalista da sociedade. Estas concepções teóricas subsidiaram a revisão da literatura sobre a organização do trabalho em saúde e as políticas públicas de formação dos trabalhadores do nível médio na área da saúde. O caminho metodológico percorrido partiu da análise de documentos legais e escuta dos agentes formuladores das políticas de Educação Profissional em Saúde, membros dos Conselhos de Saúde e de Educação do Estado do Rio Grande do Sul. Os resultados mostraram que as políticas de Educação Profissional, tanto do setor saúde como da educação, são ainda transversalizadas pela dinâmica da sociedade do capital, onde o Estado alinha-se na defesa dos interesses do setor privado, tanto na prestação de serviços, como na formação dos trabalhadores de saúde. Foi confirmada a hipótese de que as contradições dos campos da saúde e da educação se refletem nas políticas públicas, dificultando a transformação dos modelos de atenção à saúde e de formação dos trabalhadores do nível médio. A superação destas dificuldades poderá ser alcançada a partir de propostas de políticas públicas integradas entre os campos da saúde e da educação, sustentadas na reflexão teórica, no sentido da integração entre trabalho e ensino, para a formação dos trabalhadores de saúde do nível médio.

Dermic diffusion and stratum corneum: a state of the art review of mathematical models

Transdermal biotechnologies are an ever increasing field of interest, due to the medical and pharmaceutical applications that they underlie. There are several mathematical models at use that permit a more inclusive vision of pure experimental data and even allow practical extrapolation for new dermal diffusion methodologies. However, they grasp a complex variety of theories and assumptions that allocate their use for specific situations. Models based on Fick's First Law found better use in contexts where scaled particle theory Models would be extensive in time-span but the reciprocal is also true, as context of transdermal diffusion of particular active compounds changes. This article reviews extensively the various theoretical methodologies for studying dermic diffusion in the rate limiting dermic barrier, the stratum corneum, and systematizes its characteristics, their proper context of application, advantages and limitations, as well as future perspectives.

Community Health Managers: A Pilot Pedagogic Experience in the University of Rosario

The “Grupo de Estudios en Sistemas Tradicionales de Salud” from the School of Medicine of Universidad del Rosario, in agreement with the “Instituto de Etnobiología”, has designed a training course for a new health agent (the community health manager) meant to consider in its curriculum the difficulties, deficiencies and successes of the Primary Health Care Program. In particular, we have attended OMS suggestions in terms of adequate training of local leaders who should look for self-responsibility and selfdetermination in health care coverage. This training proposal is meant to take into account diverse cultures and traditions in order to offer health care models able to consider cultural particularities, epidemiological profiles, and contextual possibilities, with an intercultural point of view. Hence, the training course’s objective is to offer working tools so that community leaders be able to value and promote traditional health knowledge and practices; seek for food security by means of recovery of traditional productive systems or adaptation of appropriate technologies; environment conservation; use of medicinal plants especially in self-care, and stimulation of community and institutional health promotion activities. Preliminary evaluation suggests that this new health agent will be able to set bridges between communities and health care offers available, always looking for healthy ways of life, culturally and environmentally friendly.

Theory of planned behaviour and implementation intentions in dental attendance

The thesis used a model of health behaviour to examine the predictors of dental attendance. Older respondents who had strong intentions, low perceived vulnerability, stable plans to attend, and were influenced by significant others were more likely to have attended the dentist for preventive care in the last 12 months. The portfolio concludes that attachment theory is a useful conceptual framework for enhancing our understanding of the antecedents and consequences of childhood sexual abuse.

Maximising clinical trial participation - how important is the social context?

Individuals participate in clinical research for a variety of reasons, dependant not only on the trial phase and their own clinical status but also their sense of optimism, altruism, clinician influence, or financial gain. Practical factors influencing participation may include geographical access, motivation, availability, and language spoken. Widely-used health psychology models (e.g the Theory of Reasoned Action, the Health Belief Model) demonstrate that, in addition to these factors, the primary reason for non-participation in clinical research is social perception of risk. These models detail how beliefs and attitudes toward clinical research develop within, and are influenced by, an individual's social context. Perceived social benefits and barriers toward participation are considered alongside perceived susceptibility and severity of side-effects from participation, or symptoms of disease. A major factor in such models is the subjective norm i.e. individuals' beliefs that important others expect or wish him/her to perform this behaviour, and the motivation to act in accordance with their expectations or wishes. This includes, but is not limited to, the role of the media, peers and family members, clarification of risk associated with trial participation and discussion of comparative risk, and risk equivalence between trials and same treatment outside trials.
The workshop will involve a 30 minute presentation from the discussion leaders and a 30 minute group-work session to explore how an understanding of the social context of participation in clinical research can maximise appropriate clinical trial participation.

Mental health care system optimization from a health-economics perspective: where to sow and where to reap?

Health care expenditure (as % of GDP) has been rising in all OECD countries over the last decades. Now, in the context of the economic downturn, there is an even more pressing need to better guarantee the sustainability of health care systems. This requires that policy makers are informed about optimal allocation of budgets. We take the Dutch mental health system in the primary care setting as an example of new ways to approach optimal allocation.
