Development and Implementation of the DHAPP Military eHealth Information Network System.

BACKGROUND: As the Joint United Nations Programme on HIV/AIDS, the Global Fund, and the US President's Emergency Plan for AIDS Relief focus on reaching 90-90-90 goals, military health systems are scaling up to meet the data demands of these ambitious objectives. METHODS: Since 2008, the US Department of Defense HIV/AIDS Prevention Program (DHAPP) has been working with military partners in 14 countries on implementation and adoption of a Military eHealth Information Network (MeHIN). Each country implementation plan followed a structured process using international eHealth standards. DHAPP worked with the private sector to develop a commercial-off-the-shelf (COTS) electronic medical record (EMR) for the collection of data, including patient demographic information, clinical notes for general medical care, HIV encounters, voluntary medical male circumcision, and tuberculosis screening information. RESULTS: The COTS software approach provided a zero-dollar software license and focused on sharing a single version of the EMR across countries, so that all countries could benefit from software enhancements and new features over time. DHAPP also worked with the public sector to modify open source disease surveillance tools and open access of HIV training materials. Important lessons highlight challenges to eHealth implementation, including a paucity of technology infrastructure, military leadership rotations, and the need for basic computer skills building. CONCLUSION: While not simple, eHealth systems can be built and maintained with requisite security, flexibility, and reporting capabilities that provide critical information to improve the health of individuals and organizations.

Assessing the impact of public health interventions on the transmission of pandemic H1N1 influenza a virus aboard a Peruvian navy ship.

BACKGROUND: Limited data exist on transmission dynamics and effectiveness of control measures for influenza in confined settings. OBJECTIVES: To investigate the transmission dynamics of a 2009 pandemic H1N1 influenza A outbreak aboard a Peruvian Navy ship and quantify the effectiveness of the implemented control measures. METHODS: We used surveillance data and a simple stochastic epidemic model to characterize and evaluate the effectiveness of control interventions implemented during an outbreak of 2009 pandemic H1N1 influenza A aboard a Peruvian Navy ship. RESULTS: The serological attack rate for the outbreak was 49·1%, with younger cadets and low-ranking officers at greater risk of infection than older, higher-ranking officers. Our transmission model yielded a good fit to the daily time series of new influenza cases by date of symptom onset. We estimated a reduction of 54·4% in the reproduction number during the period of intense control interventions. CONCLUSION: Our results indicate that the patient isolation strategy and other control measures put in place during the outbreak reduced the infectiousness of isolated individuals by 86·7%. Our findings support that early implementation of control interventions can limit the spread of influenza epidemics in confined settings.

The role of disease surveillance in achieving IHR compliance by 2012.

The World Health Organization's revised International Health Regulations (IHR (2005)) call for member state compliance by mid-2012. Variation in disease surveillance and core public health capacities will affect each member state's ability to meet this deadline. We report on topics presented at the preconference workshop, "The Interaction of Disease Surveillance and the International Health Regulations," held at the 2010 International Society for Disease Surveillance conference in Park City, Utah. Presenters were from the Pan American Health Organization (PAHO), the U.S. Department of Health and Human Services (HHS), the Centers for Disease Control and Prevention (CDC), the Armed Forces Health Surveillance Center, U.S. Naval Research Unit Six, the Philippines' National Epidemiologic Center, and the French armed forces. The topics addressed were: an overview of the revised IHRs; disease surveillance systems implemented in Peru, the Philippines, and by the French armed forces; the capacity building efforts of the CDC; partnerships and contributions to IHR compliance from HHS; and the application of the IHRs to special populations. Results from the meeting evaluation indicate that many participants found the information useful in better understanding current efforts of the U.S. government and international organizations, areas for collaboration, and how the IHRs apply to their countries' public health systems. Topics to address at future workshops include progress and challenges to IHR implementation across all member states and additional examples of how disease surveillance supports the IHRs in resource-constrained countries. The preconference workshop provided the opportunity to convene public health experts from all regions of the world. Stronger collaborations and support to better detect and respond to public health events through building sustainable disease surveillance systems will not only help member states to meet IHR compliance by 2012, but will also improve pandemic preparedness and global health security.
