“…Some potential explanations for the lack of evaluation are the scarcity of human resources (program staff have not been trained on process and impact evaluation), and the low priority given to effectiveness and impact of programs when allocating of resources. Some strategies for overcoming this barrier include partnerships with academic and research sectors to support program evaluation, as demonstrated by the work of project GUIA during 8 years of partnership with recognized government and research institutions in the U.S. and Brazil [46,47]. Formal evaluations of these programs will require natural experiment designs.…”

For more than a decade, physical activity classes have been offered in public places at no cost to the participants in some Latin American cities, however, internal and external validity evidence of these programs is limited. The goals of this study were to assess, report, and compare the external validity of the Recreovia program (RCP) in Colombia, and the Academia da Cidade program (ACP) in Brazil. Interviews to assess external validity of the RCP and ACP were conducted in 2012. The interview guide was developed based on the RE-AIM framework. Seventeen key informants were selected to participate in the study. Interviews were recorded and transcribed verbatim. Transcripts were analyzed using a constant comparative qualitative method and experts validated common themes. RCP and ACP key informants reported that both programs reach underserved population. There is no information available about effectiveness. Both programs take place in public spaces (e.g., parks and plazas), which are selected for adoption mainly based on community demand. RCP and ACP offer free physical activity classes with educational and cultural components, have a strong organizational structure for implementation, and differ on schedule and content of classes. Funding sources were reported to play an important role on long-term maintenance. Facilitators and barriers were identified. Programs are similar in the reach and adoption elements; the main differences were found on implementation and maintenance, whereas information on effectiveness was not found. Reporting external validity of these programs is useful to bridge the gap between research and practice.

“…In recent years, ERGMs have found wide application in empirical research in the field of health and medical care . Recent examples include the study of referral networks among cancer services organisations , genetic variation in human social networks , the effects of collaboration among institutions on the promotion of physical activity , the impact of physicians' collaboration networks on hospitalisation cost and hospital readmission rate and the relation between competition for patients and relational coordination among hospitals . While addressing very different empirical settings, and interested in very different problems, what these studies have in common is a clear methodological commitment to modelling network mechanisms directly , rather than just attempting to ‘control for’ unspecified dependence among the observations.…”

Using original data that we have collected on referral relations between 110 hospitals serving a large regional community, we show how recently derived Bayesian exponential random graph models may be adopted to illuminate core empirical issues in research on relational coordination among healthcare organisations. We show how a rigorous Bayesian computation approach supports a fully probabilistic analytical framework that alleviates well-known problems in the estimation of model parameters of exponential random graph models. We also show how the main structural features of interhospital patient referral networks that prior studies have described can be reproduced with accuracy by specifying the system of local dependencies that produce - but at the same time are induced by - decentralised collaborative arrangements between hospitals.

“…This study is also unique in that it uses whole networks as the unit of analysis and makes statistical comparisons of different kinds of networks on network characteristics. To our knowledge, few other investigators have performed similar analyses (Fujimoto et al, 2009;Gould, 1993;Parra et al, 2011).…”

“…While this is a method commonly used in network delineation (Marsden, 1990), there may be partners that were forgotten or otherwise excluded that may have been collected if we had used a snowball sampling method or another method of partner collection. We also used previously published methods (Harris et al, 2008;Parra et al, 2011) to account for non-responders and symmetrized data to a highest level of contact and collaboration. This may have increased the number of network ties, but would do so for all networks.…”
