Approximately 30 percent of the individuals newly reported each year with HIV disease also represents new AIDS cases. This significant proportion of late diagnoses (i.e. AIDS) indicates the need for increased HIV testing, education and linkage to care in North Carolina. OBJECTIVE: This paper describes how HIV affects North Carolinians and examines the link between public health marketing campaigns and linking HIV positive patients to HIV care and treatment. METHOD: A public health marketing campaign that includes advertisements on television stations and specific web sites will be available at given times throughout the calendar year. The advertisements will include a specific call to action (either a web site address or phone number to get more information) which can be measured an evaluated to determine if the individual gets further information about getting tested for HIV and/or get into HIV care. RESULTS: A marketing campaign using television commercials was launched in June 2012. The television commercials aired during three separate time periods: June 2012 - August 2012, December 2012 - February 2012 and January 2013 - May 29, 2013. Results from that campaign showed that 54 individuals called to get more information on getting tested for HIV or getting into care for HIV. 32 of those individuals were linked to HIV care and medications. CONCLUSIONS: This campaign taught us valuable lessons, including the importance of using not only television, but expanding to the use of web sites. Many of the individuals that we want to reach use the internet as the primary means of getting information, meeting people and communication. The question then becomes, “Can advertisements encourage people to get tested for HIV or motivate them to get into care if they are HIV positive?” 4 INTRODUCTION Purpose and Urgency Thirty years after the epidemic began Human Immunodeficiency Virus (HIV) continues to remain problematic in North Carolina. HIV does not discriminate and can affect anyone of any race, gender or sexual identity. Even with HIV medication and treatment available, many HIV positive individuals find it challenging to pay for and stay adherent to these medications. While much has been achieved in the field of HIV, much work is yet to be accomplished. The HIV epidemic remains an urgent issue that must be addressed by local and state governments along with the scientific community. HIV is a communicable disease and North Carolina reports an average of 1,200 – 1,400 newly diagnosed HIV cases per year (North Carolina HIV/STD Surveillance Unit, 2015). Many of the individuals who are diagnosed with HIV do not have health insurance and cannot afford HIV medications. Even those who have health insurance may not be able to afford co-pays and multiple doctor visits. As important as surveillance, identification of new cases, and insurance coverage are, the bigger issue is medication adherence. For those who test HIV positive, it is imperative to get onto a treatment regimen and stay on it. A study conducted by Dr. Myron (Mike) Cohen at the University of North Carolina at Chapel Hill determined that an HIV positive individual who is taking their HIV medication as prescribed has a 96% chance of not transmitting the disease to their partner (Cohen, 2011). HIV is a disease that continues to stigmatize those who are positive. The majority of HIV cases in North Carolina are in the African American community – which is disproportionately 5 affected by this disease. Many African Americans who test positive are often ostracized by their families, churches or communities. This can result in HIV positive individuals hiding their disease and refusing to seek treatment until they are in medical crisis. This paper will give an overview of the HIV epidemic in North Carolina and explore the use of public health marketing campaigns in reaching the African American community, specifically men who have sex with other men (MSM), about the importance of getting tested and getting linked to care. Overview of HIV in the United States According to the Centers for Disease Control and Prevention (CDC), HIV affects the human immune system (CDC, 2015) by breaking down the specific cells in the immune system, known as T cells, making an individual more susceptible to infections. Once the T cells in the immune system are eliminated, it can advance to a more severe form known as Acquired Immune Deficiency Syndrome (AIDS). There is no cure for HIV, so once someone tests positive for this disease, then they will have it for the rest of their life (CDC, 2015). HIV is transmitted through sexual contact, or the use of contaminated drug injection paraphenalia that has been shared with someone who is HIV positive. It is not transmitted through casual contact. Once the T cells in the body drop below 200 and an opportunistic infection is identified, a patient will then be diagnosed with AIDS. It is possible to be diagnosed with HIV and AIDS at the same time. The CDC estimates that there are approximately 1.2 million people in the United States who are living with HIV disease. Of that number, it is estimated that 156,000 people are unaware that they are HIV positive (CDC, 2015). That translates to 1 in 8 people who are not aware that 6 they are HIV positive. In 2012, it is estimated that 13,000 people with an AIDS diagnosis died (CDC, 2015). In the United States, African Americans and Latinos are disproportionately affected by HIV disease. Gay and bisexual men, along with Men Having Sex with Men (MSM), are the group that has the highest number of reported cases of HIV. This population is being disproportionately affected by HIV and other sexually transmitted diseases. According to a report, a study conducted in 21 major cities found that one in three black gay and bisexual men are HIV positive (MMWR, 2010). Women and injection drug users (IDU) continue to make up a significant proportion of new diagnoses of HIV disease. IDU has become a particular concern recently due to the 2015 outbreak of HIV among IDU in Scott County, Indiana. Many states are trying to learn from this situation and implement their own prevention plans. Historically, several major urban areas such as New York City, San Francisco, Miami and Chicago have reported the highest number of new HIV cases. Over the past several years, there has been a transition. These cities continue to report high numbers of HIV cases, but states in the South are reporting high numbers of newly reported HIV cases. In 2012, the states comprising the southern portion of the United States reported over 48% of all newly diagnosed cases of HIV. During that same year, North Carolina reported 1,389 new cases of HIV and ranked 8th in the country for newly diagnosed cases of HIV (NC Epi Profile, 2015). Overview of HIV in North Carolina As of December 2013, there were 36,300 North Carolinians living with HIV. Of that number, approximately 6,500 do not know that they are HIV positive. On average, North 7 Carolina reports 1,400 – 1,500 newly diagnosed cases of HIV each year. The counties in North Carolina with the highest rates of HIV infection is Mecklenburg, Edgecombe, Cumberland, Durham and Guilford (NC Epi Profile, 2015). The demographic breakdown of HIV cases in North Carolina is similar to the reporting at the national level. African American men and women are disproportionately affected by this disease. According to the North Carolina Epidemiological Profile for December 2013, the largest group of individuals living with HIV is African American (18,377) followed by White/Caucasian (7,071). The age group with the highest number of newly diagnosed HIV cases is ages 20-29. Of the newly diagnosed cases of HIV reported in 2013, the highest risk of exposure was MSM(656 cases). Heterosexual transmission for HIV is also a high risk with 499 HIV cases reported in 2013. But MSM and IDU risk exposures made up 63% of the newly reported HIV cases in 2013 (NC Epi Profile, 2015). Barriers / Challenges to HIV Testing and Treatment There are several barriers to getting tested for HIV, begin diagnosed with HIV or AIDS and being treated for HIV. There is a great deal of stigma associated with HIV. Because of how the disease can be transmitted (through sexual contact or sharing of contaminated needles), many HIV positive patients face HIV related stigma. This is defined as negative attention or abuse that is directed towards someone who is HIV positive (AVERT, 2014). Some of the stigmatizing factors include place of residence and lack of HIV knowledge (in the patient, medical providers or general population). In addition to stigma, several of the myths associated with HIV and AIDS that were noted over 30 years ago still remain. Many people believe that HIV can be spread through casual contact and eating or drinking after someone who is HIV positive. 8 Living in a rural community is a stigmatizing factor. Many cities in North Carolina have small populations where “everyone knows everyone”. People do not want to get tested or treated for HIV where they live because they know someone who works in the medical clinics or health departments where testing and treatment are offered. Many individuals who do want to get tested for HIV will travel out of their city or even out of state to ensure that they will not be recognized. Those who are HIV positive, live in a rural area and are in need of HIV treatment are challenged due to the lack of infectious disease doctors in rural counties. Many travel two to three hours one way just to see an HIV specialist. Those living outside of rural areas face stigmatizing factors as well. Many individuals who are diagnosed with HIV are ostracized from their families, friends and churches. Some patients who are not shut out must deal with family members who are uneducated about HIV and how it is transmitted. They are forced to eat off of paper plates and use plastic cups and plastic utensils or they have to live in sheds or outbuildings away from the main house and family. Churches can openly discriminate by asking HIV positive patients and their families to leave and not attend services or participate in church activities. This is very challenging to a family dynamic because the church is the core of the community. Many families have generations that have attended the same church. For those HIV patients who rely on the church as a source of faith and fellowship, not having that in their life can be devastating and affect their health. Transportation can prove to be a major barrier in staying healthy, getting to HIV care appointments and getting HIV medications. HIV patients living in rural and urban communities must have a source of transportation in order to get back and forth to doctor’s appointments. Many HIV patients who do not have transportation or live in an area that does not have a mass 9 transit system must rely on family or friends to help get them to medical appointments. There may then be the added pressure of being able to trust people and ensuring that they can be discreet when taking them to appointments. In addition to these barriers, trust is also an issue. Many individuals do not want to be tested for HIV because they do not trust government health care. The Tuskegee syphilis study was conducted in 1932 and continued for 40 years. The study used African American men to examine the effects of syphilis. Unfortunately, many late diagnoses occur because a patient may not want to know, think that they could not be HIV positive or a doctor does not think to test a patient for HIV. Symptoms of HIV disease can mimic symptoms of a flu virus. Patients who go to a hospital emergency room for medical care could wait for hours to see a doctor, nurse practitioner, or physician assistant. When working with a patient, medical providers may not ask for a sexual history and if they present with headache, nausea, diarrhea and weight loss may be misdiagnosed and sent home. According to a report in Infectious Disease News, primary and secondary syphilis is also a concern for MSM. Physicians are being encouraged to screen MSM for all sexually transmitted diseases anytime they can and they must discuss sexual history (Infectious Disease News, 2015). The CDC recommends that MSM have an annual screening that includes testing for HIV, syphilis, chlamydia and gonorrhea. MSM who have multiple partners should be screened every six months (Infectious Disease News, 2015). 10 METHOD What is Social Marketing and how does it work? HIV prevention and education are critical in helping to control the number of new HIV cases. One of the methods used to reach individuals with HIV prevention and education messages is social marketing. In the 1970s, Philip Kotler and Gerald Zaltman realized that some of the same principles that were used to sell products could be used to sell ideas and beliefs. They define social marketing as a tool that “seeks to influence social behaviors not to benefit the marketer, but to benefit the target audience and the general society” (Weinreich, 2006). Social marketing uses four main elements – product, place, promotion and price - to reach the selected target audience. While there are several benefits to using social marketing, such as reaching a large number of people at one time, there are some challenges. In the fast paced digital world that we live in, people want information quickly and attention span may be limited. Depending on the audience, there may be many different messages that need to be created for multiple outlets. For example, if Twitter is used for an HIV prevention message it can only be 140 characters. The message would need to be very concise and impactful. If a print advertisement is placed in a newspaper or put on a web site, there may be more flexibility with the creation of the message. A social marketing campaign can be created around a health behavior that an agency would like to change. There are six phases that should be incorporated into a campaign - problem description, formative research, strategy development, intervention design, evaluation and implementation (CDC, n.d.). Messages regarding healthy eating, exercise or safe sex can be developed and branded. Then the campaign can be placed into television advertisements, print ads and electronic media such as Twitter and Facebook. 11 In order to create awareness and promote education and prevention messages, many community organizations, local health departments and federal agencies have created HIV social marketing campaigns. These campaigns are designed to promote changes and encourage healthier behavior with the call to action being “get tested for HIV” or “talk to your doctor about HIV medications and care”. Some of these campaigns have existed for several years. Literature Review of HIV Social Marketing Campaigns CDC Campaigns The Centers for Disease Control and Prevention (CDC) established the Act Against AIDS campaign in 2009. This is a large initiative that focuses on five different components – HIV awareness, HIV testing, HIV prevention, HIV care and treatment and HIV providers. Act Against AIDS has several smaller campaigns under its umbrella and was created due to lack of awareness about the disease (CDC, 2015). Act Against AIDS focuses messages to high-risk groups while attempting to raise awareness among all populations. Included under the Act Against AIDS campaign arethe following social marketing campaigns including “We Can Stop HIV One Conversation at a Time”, “Let’s Stop HIV Together”, “Take Charge. Take the Test.”, “Testing Makes Us Stronger”, “Reasons/Razones”, “Start Talking. Stop HIV”, “HIV Treatment Works”, “Prevention IS Care” and “One Test. Two Lives.” Each of these initiatives focus on one population – African American MSM, Latino MSM, gay and bisexual men, African American women and HIV medical providers. One of the campaigns that specifically focuses on young, African American MSM is “Testing Makes Us Stronger”. The goal of the campaign is to promote HIV testing with the focus being empowerment – black gay and bisexual men should feel empowered and they can achieve 12 this by getting tested for HIV and knowing their HIV status. Positive images of young, African American men are shown. Some of these photos depict men standing together embracing or holding hands. These types of images can help connect the audience to the campaign and make them feel like “that could be me”. There are many promotional materials for this campaign including posters and flyers that can be displayed in local health departments, clinics and medical offices. Along with those, there are materials for providers that can be used to discuss HIV treatment and care options with patients. The CDC wants to ensure that women are being tested for HIV. There are high numbers of African American women that are being diagnosed with this disease. Of the 1.1 million people currently living in the U.S. who are HIV positive, 24% are women. (Kaiser Family Foundation, 2015). “Take Charge. Take the Test.” was created in 2012 and encourages African American women between the ages of 18 and 34 to get tested for HIV (CDC, 2015). Through the information included in this campaign, they are educated on the risk factors for HIV and encouraged to get tested for HIV so that they can feel empowered and take control of their health. Other Community Based Campaigns within the U.S. While the CDC conducts multiple national and international campaigns, local social marketing campaigns have also been created to address specific local needs. In San Francisco, the “Healthy Penis” campaign was created to address a sharp increase in syphilis cases. The campaign was targeted in neighborhoods with the highest concentrations of gay and bisexual men. There were posters and palm cards that were distributed in clubs, bus shelters and other high traffic areas promoting the need to get tested for syphilis. 13 In 2007, the Bronx had the highest HIV death rate in New York City. Almost one in four residents were diagnosed with AIDS (NYC Dept of Health, 2011). As a result, the New York City Department of Health created and launched “the Bronx Knows” which was designed as an initiative to encourage and increase voluntary HIV testing for residents between the ages of 13 and 64. The campaign featured posters encouraging residents to get tested. The health department partnered with community health organizations, churches, hospitals and others to conduct over 600,000 tests. Of that number, 4,800 were diagnosed with HIV. “Get Real. Get Tested. Get Treatment.” Campaign Development In early 2006, the State Health Director for North Carolina gave the Branch Head at the Communicable Disease Branch, North Carolina Division of Public Health a directive – develop an HIV testing campaign utilizing social marketing and street outreach to get people tested for HIV. During this same time, the CDC issued new guidelines for routine HIV testing. The guidelines stated that everyone between the ages of 13 and 64 should be tested for HIV and those at high risk for contracting HIV should be tested at a minimum of once per year (MMWR, 2006). “Get Real. Get Tested.” was developed with three goals in mind: 1) to test and educate people for HIV and sexually transmitted diseases, 2) identify persons living with HIV/AIDS who need care, and 3) to link HIV-positive patients to care. The campaign was billed as “North Carolina’s HIV education and testing campaign”. Once a plan was established, a media partner was brought on board to help create and produce campaign television and radio commercials. These commercials began airing during prime time programming across multiple media outlets in North Carolina. By getting educational messages out to the general public, we believe that 14 they will be more inclined to be tested for HIV and other sexually transmitted diseases and to learn about prevention methods and education. These commercials featured local people who worked at local health departments and HIV service organizations. This was done intentionally so that when someone went to one of these places to get tested; they would feel more comfortable seeing someone that they recognized. The call to action on each of these commercials was to a phone number which the viewer could call and get more information about HIV or get information on where they could get tested for HIV in their area. This method provided some anonymity for people that had specific questions about HIV and their status, but may have been concerned about going to local organization to ask the questions in person. In order to generate interest, the staff at the Communicable Disease Branch met with local health departments across the state and also met with media to create awareness, screen the campaign commercials and discuss the importance of getting tested for HIV. Once that took place, the staff at the Branch began the second phase of the campaign. Activities The second phase of the campaign began in December 2006 with the first “Get Real. Get Tested.” community testing event in Fayetteville. In advance of this testing event, the campaign commercial was aired in Fayetteville and multiple media interviews were conducted in order to promote the testing event. The staff at the Communicable Disease Branch partnered with the local health department in order to determine the best areas to offer testing. There were multiple locations set up for HIV screening including door to door, clubs and community locations such 15 as a grocery or discount store. The promotion that was done for this event resulted in over 300 people getting tested. These testing events continued across the state through 2009. Beginning in 2010, the campaign went through some changes. Due to decreased resources, both financial and personnel, the staff at the Branch began to focus on specific groups to screen for HIV. At that time, there were two issues that needed to be addressed: the number of new HIV cases begin reported in African American men was increasing and emphasis needed to be placed on getting into HIV care and treatment. The decision was made to create two new commercials, one focusing specifically on African American men who have sex with other men and the second focusing on the importance of HIV positive individuals getting into HIV care and treatment. In creating the first commercial, it was somewhat controversial because a commercial featuring MSM and targeting MSM had never been done at the local level. The commercial had to be done in such a way that the subtle messages would reach the right audience. The individuals featured in the commercial were young African American men who were known in the community. The call to action was a phone number and web site address that viewers could use to get more information on HIV and getting tested. The commercials used in the campaign took four to six weeks to create and get on the air. Due to the subject matter, this particular commercial took nine months. The second commercial featured a local infectious disease doctor who met with two “patients”. The doctor looked directly into the camera and talked about the importance of getting on and adhering to an HIV medication treatment plan. 16 RESULTS Campaign Results / Successes Beginning in 2012, a marketing campaign was launched using these two television commercials. The television commercials aired during three separate time periods: June 2012 August 2012, December 2012 - February 2012 and January 2013 - May 29, 2013. Results from that campaign showed that 54 individuals called to get more information on getting tested for HIV or getting into care for HIV. 32 of those individuals were linked to HIV care and medications. While the campaign results were not viewed successful by the CDC, the staff at the Communicable Disease Branch felt it was a success because of the people that were directly linked to HIV care and medications. Getting an HIV positive person on HIV medications will help reduce the possibility of transmitting the disease to someone else. Campaign Results / Challenges Even with the challenges, there were many successes during the “Get Real. Get Tested.” campaign. In 2009, the State Lab for Public Health in North Carolina has reported a73% increase in HIV tests processed from 144,000 in 2006 to 250,000 in 2009. Between 2006 and 2012, there were over 4,500 people who were tested for HIV and sexually transmitted diseases at a Get Real Get Tested event. The campaign was presented at state and national conferences. There were several organizations across the country and internationally that wanted to know how to conduct a similar type of campaign. The major problem with this social marketing approach was that people visiting the web site or calling the number could not be tracked. Because “Get Real. Get Tested.” is a campaign that is managed by the Division of Public Health; there was no ability to have a separate web 17 site. There was one web page that was on the Division web site and it was very hard to find. Many young people do use government web sites to get information. There was no way to track the number of people that visited the web site as a result of the commercial and there were no staff available to track the number of calls that were generated as a result of the commercial. Management at the Communicable Disease Branch assigned staff from the AIDS Drug Assistance Program (ADAP) to handle any incoming calls from people who saw the commercial. A basic tracking system was put in place to capture demographics, location and any treatment history or questions pertaining to HIV. CONCLUSIONS / RECOMMENDATIONS Future Research It is critical that further work be conducted with MSM to better understand how they would best be reached with public health messages. Currently, North Carolina is experiencing a sharp increase in syphilis and MSM are being disproportionately affected. While the “Get Real. Get Tested. Get Treatment.” campaign did not use social media, it is important that this component be considered moving forward. In early 2015, the Communicable Disease Branch conducted two focus groups with MSM to learn how they were communicating with each other. All of the focus group participants were using social media (Facebook, Instagram, other MSM sites) to meet and communicate with each other. Additional focus groups should also include potential public health messages to determine the response with an opportunity to develop messages that they feel would be appropriate. 18 Leadership Recommendations My leadership training throughout this program has shown me some areas where I could improve when conducting future public health or social marketing campaigns. When I came into public health, I had one job that was fairly straightforward – establish a team that will be dedicated to an a public health marketing campaign focused on HIV testing and education. In order for this project to be successful, I had to become extroverted. The job involved talking to my team on a daily basis and working with several staff at local health departments and community organizations that would require building strong relationships and a lot of public speaking. During the campaign, my leadership style developed so that I was always working to include my team and other staff working on the campaign. I still remained thoughtful and intuitive, but I learned to understand their strengths and weaknesses as well as promote their ideas. Another step in making the campaign successful was promoting their leadership to upper management. I was always conscious of acknowledging their skills and strengths. I did not want to be the only “face” of the campaign. Individuals from the team took the lead on several events and presented the campaign at state and national conferences. I would consider this one of the strengths of my leadership style. I believe that it is important to build the skills of others so that they remain happy and reach their full potential – I don’t ever want to hold anyone back. This is one of the most important lessons that I have learned in the public health leadership program – the power of inclusion. A team that is part of an organization or a project will dictate success or failure. As Claudia Fernandez states, “positive personal regard” focuses on how a team speaks to one another, how we appreciate one another and how we listen to each 19 other (Fernandez, 2007). Ensuring that a public health marketing team is cohesive and working together can help ensure a successful campaign. References: AVERT, (2014). “HIV and AIDS Stigma and Discrimination”.
