Evaluating the U.S. Global Health Policy Initiative

In understanding that the efforts made in improving global health affects the health of U.S. citizens, a policy analysis of President Barak Obama's Global Health Initiative was conducted. Using materials gathered from experts in the field of health and their findings and recommendations, paired with the current policies of other G8 countries that pledged to support the efforts of improving global health, the analysis was conducted using four specifically defined criteria. The set criteria determine the appropriateness, responsiveness, effectiveness and equity of Obama's GHI in comparison to other G8 country health policies and overall global health priorities. G8 countries without a specific global health policy, or with a policy that was not in English were excluded from this study and Switzerland, headquarters of the World Health Organization, was added due to its membership in the OECD, and the fact that it has a specific foreign health policy. In evaluating the U.S. Global Health Initiative it is clear that in terms of implementing foreign policy specific to health, the United States is on the forefront alongside the United Kingdom and Switzerland. Other G8 Countries have pledged monies and in order to Millennium Development Health Goals by 2015. The U.S. Global Health Policy does not address issues necessary to meet Millennium Development Goals in Health. Instead the Global Health Initiative is focused narrowly on Fighting and rolling back the HIV/Aids Epidemic based on President Bush's PEPFAR policy. Policy recommendations for a more effective and efficient Global Health Initiative include building upon the PEPFAR policy foundation in order to strengthen health systems worldwide, allowing individuals and communities to combat unnecessary death and disease through research, education, and other preventative methods.^

The global initiative to eradicate polio- A review of Nigeria's situation

Poliomyelitis is one of the worlds remaining vaccine preventable infectious diseases. In 1988 the World Health Assembly in its general assembly resolved to eradicate polio in the year 2000 and the Global Initiative to Eradicate Polio was launched. ^ This initiative sprang from the successful eradication of smallpox from the world in the year 1979, and the World Health Organization sought to eradicate polio from the world's populations by the year 2000. ^ Several years have passed since this objective was launched, and while some advances have been made, the goal of global eradication remains elusive. At this present time (2007), only four countries are considered polio endemic regions (areas in which the transmission of wild poliovirus has never been truncated). These countries are Nigeria, India, Pakistan and Afghanistan. ^ This descriptive study seeks to examine the process and progress of polio eradication worldwide, with particular emphasis on the polio eradication efforts in Nigeria, problems encountered and progress that has been made towards attaining this goal. ^ The methodology of this study is an extensive examination of documentation and data from the Global Initiative to Eradicate Poliomyelitis (GPEI), the World Health Organization through the World Health Organization Library Information Service (WHOLIS), UNICEF, the Centers for Disease Control and related peer reviewed journals. ^

Implementing the Global Plan of Action on workers' health: Components to protect health care workers

Health care workers are at risk for percutaneous injuries and infection with blood born pathogens due to needle stick injuries with contaminated needles. The most common pathogens transmitted are hepatitis B, and C and HIV/AIDS. According to the WHO Global Plan of Action (GPA) a large gap exist between and within countries with regards to the health status of workers and their exposure to occupational risk. Less than 15% of the world's work forces have access to occupational health services despite the availability of effective interventions that can prevent occupational hazards, or protect and promote health in the workplace. The 2006 World Health Report declared that there is a global crisis in the health care work force. 1 in 400 of the world's health care workers work in Sub-Saharan Africa. 1 in 3 work in the U.S or Canada. The shortage of health care workers is worst in Southeast Asia and Sub-Saharan Africa. These countries have the highest burden of exposure to contaminated sharps. They rarely, if ever monitor the exposure or health impact of occupational ailments and injuries on workers. Many injuries are unreported. Occupational health services in the developing world are virtually non existent. Many health care workers leave their home countries and go to work in other countries where the working conditions, occupational services included, are better. The inability of countries to provide the necessary numbers of health care workers to provide a high level of health coverage is a threat to national and international public health security. Immunizing health care workers against hepatitis B and providing them PEP, PPE, education and safety training is an essential part of increasing and maintaining the numbers of health care workers in the critical shortage areas. ^

Endemic tuberculosis, the homeless, and public transportation: A merging of geographical information systems surveillance and the Houston Tuberculosis Initiative Surveillance project

To reach the goals established by the Institute of Medicine (IOM) and the Centers for Disease Control's (CDC) STOP TB USA, measures must be taken to curtail a future peak in Tuberculosis (TB) incidence and speed the currently stagnant rate of TB elimination. Both efforts will require, at minimum, the consideration and understanding of the third dimension of TB transmission: the location-based spread of an airborne pathogen among persons known and unknown to each other. This consideration will require an elucidation of the areas within the U.S. that have endemic TB. The Houston Tuberculosis Initiative (HTI) was a population-based active surveillance of confirmed Houston/Harris County TB cases from 1995–2004. Strengths in this dataset include the molecular characterization of laboratory confirmed cases, the collection of geographic locations (including home addresses) frequented by cases, and the HTI time period that parallels a decline in TB incidence in the United States (U.S.). The HTI dataset was used in this secondary data analysis to implement a GIS analysis of TB cases, the locations frequented by cases, and their association with risk factors associated with TB transmission. ^ This study reports, for the first time, the incidence of TB among the homeless in Houston, Texas. The homeless are an at-risk population for TB disease, yet they are also a population whose TB incidence has been unknown and unreported due to their non-enumeration. The first section of this dissertation identifies local areas in Houston with endemic TB disease. Many Houston TB cases who reported living in these endemic areas also share the TB risk factor of current or recent homelessness. Merging the 2004–2005 Houston enumeration of the homeless with historical HTI surveillance data of TB cases in Houston enabled this first-time report of TB risk among the homeless in Houston. The homeless were more likely to be US-born, belong to a genotypic cluster, and belong to a cluster of a larger size. The calculated average incidence among homeless persons was 411/100,000, compared to 9.5/100,000 among housed. These alarming rates are not driven by a co-infection but by social determinants. The unsheltered persons were hospitalized more days and required more follow-up time by staff than those who reported a steady housing situation. The homeless are a specific example of the increased targeting of prevention dollars that could occur if TB rates were reported for specific areas with known health disparities rather than as a generalized rate normalized over a diverse population. ^ It has been estimated that 27% of Houstonians use public transportation. The city layout allows bus routes to run like veins connecting even the most diverse of populations within the metropolitan area. Secondary data analysis of frequent bus use (defined as riding a route weekly) among TB cases was assessed for its relationship with known TB risk factors. The spatial distribution of genotypic clusters associated with bus use was assessed, along with the reported routes and epidemiologic-links among cases belonging to the identified clusters. ^ TB cases who reported frequent bus use were more likely to have demographic and social risk factors associated with poverty, immune suppression and health disparities. An equal proportion of bus riders and non-bus riders were cultured for Mycobacterium tuberculosis, yet 75% of bus riders were genotypically clustered, indicating recent transmission, compared to 56% of non-bus riders (OR=2.4, 95%CI(2.0, 2.8), p<0.001). Bus riders had a mean cluster size of 50.14 vs. 28.9 (p<0.001). Second order spatial analysis of clustered fingerprint 2 (n=122), a Beijing family cluster, revealed geographic clustering among cases based on their report of bus use. Univariate and multivariate analysis of routes reported by cases belonging to these clusters found that 10 of the 14 clusters were associated with use. Individual Metro routes, including one route servicing the local hospitals, were found to be risk factors for belonging to a cluster shown to be endemic in Houston. The routes themselves geographically connect the census tracts previously identified as having endemic TB. 78% (15/23) of Houston Metro routes investigated had one or more print groups reporting frequent use for every HTI study year. We present data on three specific but clonally related print groups and show that bus-use is clustered in time by route and is the only known link between cases in one of the three prints: print 22.
