A meta-avaliação como instrumento para a qualificação da avaliação de políticas públicas de saúde

Trata-se da meta-avaliação de um processo avaliativo desenvolvido por secretários e assessores técnicos municipais de uma região de saúde do estado de São Paulo, com foco nos critérios de utilidade e participação. É uma pesquisa qualitativa, cuja base empírica foi 1) o material produzido em sete oficinas realizadas com os representantes municipais, com vistas à avaliação de um aspecto da linha de cuidados em saúde sob a ótica da integralidade; e 2) as entrevistas semiestruturadas realizadas com os mesmos atores após a finalização do processo avaliativo. Para a avaliação do critério de utilidade, utilizou-se principalmente o referencial de KIRKHART (2000), com o objetivo de ampliar a análise para além do uso instrumental dos achados avaliativos e focá-la na identificação de influências múltiplas exercidas por um fenômeno complexo como um processo avaliativo. A análise do critério participação se deu com base no referencial de COUSINS e WHITMORE (1998), buscando a identificação no material empírico de decisões ou aspectos contextuais que fizeram com que a opção participativa fosse aprofundada ou limitada no processo em foco. O trabalho destaca a importância de explicitar pressupostos que baseiam a metodologia da avaliação/ meta-avaliação escolhida, e a necessidade de se buscar referenciais teóricos de análise compatíveis com a opção realizada, frisando a inexistência de posturas neutras ou estudos totalmente objetivos; e a importância de capacitar avaliadores a acompanharem a demanda dos participantes de um processo participativo com a flexibilidade necessária para conferir-lhe o maior aproveitamento possível. Conclui-se pela viabilidade, com vantagens, da realização de processos participativos locais com gestores na Saúde Pública, destacando a possibilidade de ganhos em formação e o enriquecimento dos processos de negociação em nível do território, de forma coerente à política de construção das regiões de saúde no SUS.

Predicting health programme participation: A gravity‐based, hierarchical modelling approach

Statistical analyses of health program participation seek to address a number of objectives compatible with the evaluation of demand for current resources. In this spirit, a spatial hierarchical model is developed for disentangling patterns in participation at the small area level, as a function of population-based demand and additional variation. For the former, a constrained gravity model is proposed to quantify factors associated with spatial choice and account for competition effects, for programs delivered by multiple clinics. The implications of gravity model misspecification within a mixed effects framework are also explored. The proposed model is applied to participation data from a no-fee mammography program in Brisbane, Australia. Attention is paid to the interpretation of various model outputs and their relevance for public health policy.

A Sexual Health Programme Implemented in a Psychiatric Inpatient Unit

Research has shown that people with a mental illness are an at-risk group for sexually transmitted infections. A programme for preventing risk behaviours for sexually transmitted infections among people with psychiatric disorder was designed and implemented by mental health occupational therapists. This programme used an interactive didactic approach to provide education and awareness of sexual health issues to acute psychiatric inpatients. Twenty-four participants completed a sexual health questionnaire, which was designed for this study, both before and after attending the programme. They had a higher than expected knowledge of sexually transmitted infections and safe sex practices at pre-test. The education programme resulted in a statistically significant but modest increase in sexual health knowledge. These findings indicate that there are benefits in providing sexual health education to clients with a mental illness. Further programme development should be directed towards sexual health decision-making and behaviour change.

Meta-evaluation to improve learning, evaluation capacity development and sustainability : Findings from a participatory evaluation project in Nepal

Recent studies suggest that meta-evaluation can be valuable in developing new approaches to evaluation, building evaluation capacities, and enhancing organizational learning. These new extensions of the concept of meta-evaluation are significant, given the growing emphasis on improving the quality and effectiveness of evaluation practices in the South Asian region. Following a review of the literature, this paper presents a case study of the use of concurrent meta-evaluation in the four-year project Assessing Communication for Social Change which developed and trialled a participatory impact assessment methodology in collaboration with a development communication Non-government organization (NGO) in Nepal. Key objectives of the meta-evaluation included to: continuously develop, adapt and improve the impact assessment methodology, Monitoring and Evaluation (M&E) systems and process and other project activities; identify impacts of the project; and build capacities in critical reflection and review. Our analysis indicates that this meta-evaluation was essential to understanding various constraints related to the organizational context that affected the success of the project and the development of improved M&E systems and capacities within the NGO. We identified several limitations of our meta-evaluation methods, which were balanced by the strengths of other methods. Our case study suggests that as well as assessing the quality, credibility and value of evaluation practices, meta-evaluations need to focus on important contextual issues that can have significant impacts on the outcomes of participatory evaluation projects. They include hierarchical organizational cultures, communication barriers, power/knowledge relations, and the time and resources available. Meta-evaluations also need to consider wider issues such as the sustainability of evaluation systems and approaches.

Conjugated linoleic acid and human health: a critical evaluation of the evidence

Purpose of review: This review critically evaluates studies investigating the effects of conjugated linoleic acid on human health, including effects on body composition, blood lipids, liver metabolism, insulin sensitivity and immune function. It focuses mainly on human intervention studies, but includes some reference to animal and cellular studies which provide insight into potential molecular mechanisms of action of conjugated linoleic acid. Recent findings: Human studies continue to report inconsistent effects of conjugated linoleic acid on human health. Some of these reports are based on overinterpretation of marginal effects of supplementation. Recent data suggest that the effects of the substance may be isomer dependent and that cis-9, trans-11 and trans-10, cis-12 conjugated linoleic acids have opposing effects on blood lipids and on metabolism in adipocytes and hepatic cells. Summary: Claims that conjugated linoleic acid is beneficial for health remain as yet unconvincing. Human studies investigating the effects of conjugated linoleic acid supplements have tended to use mixtures of isomers and have been inconsistent. More recent studies have attempted to use relatively pure preparations of single isomers and these studies suggest that the effects of conjugated linoleic acid may be isomer-specific. These recent data suggest a relative detrimental effect of trans-10, cis-12 conjugated linoleic acid on blood lipids. There appears to be little effect of conjugated linoleic acid on immune function and the effects on insulin sensitivity remain unclear.
