Identifying Effective Approaches for Dissemination of Clinical Evidence--Correlation Analyses on Promotional Activities and Usage of a Guideline-Driven Interactive Case Simulation Tool in a Statewide HIV-HCV-STD Clinical Education Program.

Dissemination of the latest clinical evidence to community-based healthcare providers is a critical step to translate biomedical knowledge into clinical practice. We performed a study to analyze the correlations between the promotional activities and the usage of a guideline-driven interactive case simulation tool (ICST) for insomnia screening and treatment in a statewide HIV-HCV-STD clinical education program. For this purpose, we tracked users' interactions with the ICST and the sending of promotional email newsletters during a study period of 44 weeks.

Evaluation of an Enhanced Role-Based Access Control model to manage information access in collaborative processes for a statewide clinical education program.

Background: Managing information access in collaborative processes is a critical requirement to team-based biomedical research, clinical education, and patient care. We have previously developed a computation model, Enhanced Role-Based Access Control (EnhancedRBAC), and applied it to coordinate information access in the combined context of team collaboration and workflow for the New York State HIV Clinical Education Initiative (CEI) program. We report in this paper an evaluation study to assess the effectiveness of the EnhancedRBAC model for information access management in collaborative processes when applied to CEI.

Assessing the usage of a guideline-driven interactive case simulation tool for insomnia screening and treatment in an HIV clinical education program.

Interactive case simulation tools (ICSTs) are important vehicles to disseminate medical knowledge. We conducted a study to examine the usage of an insomnia screening and treatment case simulation tool in an HIV clinical education program. Using system usage diagrams (SUDs) as an instrument, we quantified visit frequency and length of stay for different types of system resources.

Cost-effectiveness of long-lasting insecticide-treated hammocks in preventing malaria in South-central Vietnam.

Background: Despite much success in reducing the burden of malaria in Vietnam, pockets of malaria persist and eliminating them remains an important development goal. In central Vietnam, insecticide-treated hammocks have recently been introduced to help counter the disease in the highly forested, mountainous areas, where other measures have so far been unsuccessful. This study assesses the cost-effectiveness of using long-lasting insecticide-treated hammocks in this area.

An enhancement of the role-based access control model to facilitate information access management in context of team collaboration and workflow.

Although information access control models have been developed and applied to various applications, few of the previous works have addressed the issue of managing information access in the combined context of team collaboration and workflow. To facilitate this requirement, we have enhanced the Role-Based Access Control (RBAC) model through formulating universal constraints, defining bridging entities and contributing attributes, extending access permissions to include workflow contexts, synthesizing a role-based access delegation model to target on specific objects, and developing domain ontologies as instantiations of the general model to particular applications. We have successfully applied this model to the New York State HIV Clinical Education Initiative (CEI) project to address the specific needs of information management in collaborative processes.

Social determinants of long lasting insecticidal hammock use among the Ra-glai ethnic minority in Vietnam: implications for forest malaria control.

Background: Long-lasting insecticidal hammocks (LLIHs) are being evaluated as an additional malaria prevention tool in settings where standard control strategies have a limited impact. This is the case among the Ra-glai ethnic minority communities of Ninh Thuan, one of the forested and mountainous provinces of Central Vietnam where malaria morbidity persist due to the sylvatic nature of the main malaria vector An. dirus and the dependence of the population on the forest for subsistence--as is the case for many impoverished ethnic minorities in Southeast Asia.

Plasmodium knowlesi malaria in Vietnam: some clarifications.

A recently published comment on a report of Plasmodium knowlesi infections in Vietnam states that this may not accurately represent the situation in the study area because the PCR primers used may cross-hybridize with Plasmodium vivax. Nevertheless, P. knowlesi infections have been confirmed by sequencing.

Epidemiology of forest malaria in central Vietnam: a large scale cross-sectional survey.

In Vietnam, a large proportion of all malaria cases and deaths occurs in the central mountainous and forested part of the country. Indeed, forest malaria, despite intensive control activities, is still a major problem which raises several questions about its dynamics.A large-scale malaria morbidity survey to measure malaria endemicity and identify important risk factors was carried out in 43 villages situated in a forested area of Ninh Thuan province, south central Vietnam.
