December 1st of every year is designated as World AIDS Day, a day devoted to increasing knowledge and awareness about the impact of HIV/AIDS around the world. This year is no different, and over the last few months and years some exciting things have been happening regarding HIV/AIDS.

The year 2013 has become known as the “turning point” or “tipping point” in the HIV/AIDS epidemic. This describes the fact that 2.3 million people began anti-retroviral medication in 2013 while only 2.1 million new infections were diagnosed. In other words, more people are receiving treatment and fewer people are becoming infected than ever before. If we keep this accelerating HIV scale-up through 2020, UNAIDS predicts we could see the end of HIV/AIDS by 2030

In the United States there has been a lot of media coverage, over the last year or two, surrounding pre-exposure prophylaxis (PrEP) for use by HIV-negative people to prevent HIV infection. PrEP is daily medication regimen utilizing an HIV drug called Truvada. Studies have shown that people who take PrEP as directed were 92% less likely to contract HIV. However, although it is increasing, PrEp usage remains lower than anticipated. Some barriers include a lack of PrEP awareness in people who are most at risk for HIV, some medical provider resistance to prescribing PrEP and some inconsistent insurance coverage. Additionally, PrEP continues to suffer from an image problem. When PrEP first became available, many critics were skeptical of its effectiveness in real-world settings and thought that it would undo years of work to educate folks about the dangers of HIV/AIDS. Critics also thought that being able to take a daily drug to prevent HIV would promote promiscuity and unsafe sex. A recent study in JAMA Internal Medicine proves the critics wrong on some of their fears.

An HIV/AIDS vaccine has been on the horizon ever since the epidemic was discovered. However, as we learned more about HIV, it became apparent that developing a vaccine was going to be a challenging effort. While there continue to be many HIV vaccines at various stages of development, scientists are excited about one being developed by one of the scientists who identified HIV as the cause of AIDS, Dr. Robert Gallo. His team at the University of Maryland School of Medicine’s Institute of Human Virology is beginning human trials on a potentially groundbreaking HIV vaccine. Instead of targeting different HIV viral markers to help the immune system recognize and eliminate HIV-infected cells, Dr. Gallo and his team’s vaccine targets HIV when it enters the body to prevent it from infecting cells.

All of these promising developments relating to HIV/AIDS should not overshadow the challenges that still lie ahead. Many people do not know they have HIV because they’ve never been tested. The Berkshire town of Reading in the UK is expanding its HIV testing program by offering free tests because it has more than double the UK average of HIV-positive people. The number of HIV-positive people in Russia continues to increase and has reached almost 1 million people. Some countries are passing anti-gay legislation and there is a direct link between criminalizing laws and increased rates of HIV. These are the challenges some parts of the world face in the efforts to end the HIV/AIDS epidemic.

World AIDS Day provides a way for everyone to get involved in the fight against HIV/AIDS. It’s an annual day to think about the people who’ve lost their lives to AIDS-related illnesses and to champion efforts to prevent more people from losing their lives due to HIV/AIDS related causes. This December 1st do a little research, learn about the burden of HIV/AIDS in your community, and decide how to get involved. Together we can end HIV/AIDS in our lifetime.

Investing in Healthcare to Put a Dent in Poverty

Health and poverty are intricately related. Evidence suggests that there is a positive correlation between health and poverty. People with limited resources in low- and middle-income countries (LMICs) are reported to have limited access to healthcare compared to their wealthier counterparts (Wagstaff, 2002). However, other evidence has shown that health expenditure can push households into poverty (Kruk et al, 2009). Tackling either is a priority for governments to improve the welfare of people. The poor are more likely to need healthcare for many reasons including a lack of safe drinking water, a balanced diet, adequate shelter, and protection against harsh environmental conditions. Because of the increased need for healthcare, the poor incur increased spending on already limited resources, and are likely to experience catastrophic expenditure. Reducing healthcare expenditure by the poor has the potential to be a viable mechanism against deepening of poverty.

Reducing extreme poverty is a major goal of the Millennium Development Goals (MDGs) and was also considered in the formulation of the post-2015 agenda. Countries all over the world are grappling with measures to reduce income inequality and poverty. In developing countries, this is more apparent through the increase of micro credit schemes, subsidies, and social safety nets for the most vulnerable. However, evidence has shown that in spite of efforts from nations and development partners, more needs to be done to eradicate extreme poverty (Laterveer et al. 2003). Poverty and access to healthcare have been subjects of research and policy. Poverty can be viewed not only as a conception of material and income deprivation (Deaton and Zaidi, 2002) but also as the lack of opportunities for an individual to lead a life he/she values (Sen, 1999). Using this concept, empowering people to live healthy lives can be seen as an initiative to overcome poverty. However, when poverty is viewed as a deprivation of income and assets, initiatives are channeled that directly improve household expenditure; when in relation to health, initiatives that lower expenditure on health to avoid catastrophic expenditure.

The World Health Organization (WHO; 2000) has advocated for health financing measures that provide financial protection from catastrophic health expenditure. Catastrophic expenditure is a leading cause of impoverishment in many countries. Efforts to prevent catastrophic expenditure oh health have been primarily through insurance. However, in many LMICs it is not effective and/or is beyond the reach of the poor either by being too costly or by not providing adequate coverage (McIntyre, 2006). Thus, the world health report (WHO, 2010) advocated for universal public finance (UPF) as a strategy to promote universal health coverage. UPF means that governments finance interventions for people regardless of who receives it and who provides it. UPF has been in practice in many high-income countries where many necessary interventions are covered. In LMICs however, UPF is limited by targeting a set of interventions tagged as the essential health package, which means many services are excluded and require user payments at the point of care.

For example, extended cost-effectiveness analysis (EECA) was used to assess the effectiveness and reduction in financial risk afforded by a public package of interventions initiated by the government of Ethiopia (Verguet et al, 2015). The interventions examined included services for vaccination, treatment of some conditions, caesarean section surgery, and tuberculosis DOTS. Their analysis focused on UPF where there is no out-of-pocket expenditure to cover costs incurred for each of the nine interventions. They estimated the annual number of deaths averted and the annual total financial protection afforded by the reduction in out-of-pocket expenditure associated with each intervention. The results for intervention costs, health gains and financial protection varied across the interventions but it was concluded that the interventions were cost-effective and prevented cases of poverty among those at lowest income level. Such evidence can be used to convince governments to increase funding of health services with the objective of improving health status of citizens and eradicating extreme poverty among the population.

Corporate Responsibility and Duty of Care - Health Insurance and Assistance

"Between one in two and one in three expatriates has no international health insurance" International Private Medical Insurance Magazine REPORT: International And Expatriate Healthcare And Insurance 2014

I believe this to be a very accurate statement notably, with regard to the African continent (where I spend most of my time), this figure might even be flattering to some companies employing expat staff in Africa.

The globally mobile population has grown dramatically. There are over 50 million expatriates, and by 2020 this will be 60 million. 232 million people now live away from their country of birth. Between one in two and one in three expatriates has no international health insurance, although a minority is covered by domestic health insurance. Several countries seek to get expatriates and migrants to pay for healthcare or have compulsory health insurance.

This is a disturbing issue, as too many companies are happy to send their staff abroad, or to remote work sites, without any or inadequate medical cover; be it insurance or assistance. This shows very poor duty of care. In discussions with some of these companies, when trying to assist them with advice on even basic assistance packages or client managed services, their responses are troubling; when viewed against the light of corporate responsibility and duty of care. To defer the responsibility to the employee and abdicate corporate responsibility, should be cause for concern.

The duty of care of the employer, is a term that is often thrown about and The UN Global Compact, is one way that companies are being encouraged to show a greater duty of care, although some would cynically say that Corporate Social Responsibility is a box-ticking exercise, companies are just paying lip service, but do no more than is necessary to avoid affecting the bottom line. The UN Global Compact, is engaging over 8,000 companies in more than 145 countries on human rights, labour standards, environment and anti-corruption, hopefully at the same time pushing to commit to a sustainable workforce, via duty of care and corporate social responsibility.

The level of care offered by companies, will depend where the company is registered, as to what laws could be enforceable, hence most companies register an off-shore shell for hiring, staffing and contracts. (this is in itself a topic for another day – relating to contracts, taxes etc.)

Possibly other avenues should be explored, with respect to medical assistance/insurance; by pushing that investors use their muscle, ensuring that their investment capital is being well managed. Staff that cannot be properly cared for (ex-pat and local), via medical cover that is in place, place a further drain on company resources, shifting capital away from its intended purpose. A well managed corporate health care plan, ensures ongoing confidence in the company.

Till now I have only been speaking about expat staff, but the issue of medical care for local staff would also need to be addressed, in fact poor care for expat staff, could be viewed as an indicator of poor care for local staff. The ever growing impact of business on society means that staff, investors and consumers expect corporate power to be exerted responsibly, the corporate community will have to step up its game and build greater trust with respect to duty of care. Business are being expected to do more in areas that used to be the exclusive domain of the public sector – ranging from health, education and to community investment.

Having insurance/assistance programs from reputable companies, linked to well managed onsite managed health care programs, which is in place for ALL staff, makes good business sense. This then empowers staff to work safely in environments that might be deemed risky, allowing them to work with confidence and be fully focused on their daily tasks.
