Monks heading into a temple

Only a few years ago, communities of Buddhist monks were the main source of care for Thais with AIDS. Now, Thailand has a national program offering antiretroviral treatment to its HIV-positive citizens, the first of its kind in Asia.

At the closing session of the 2002 international AIDS conference at Barcelona, Dr. Paul Farmer, director of the pioneering Partners for Health AIDS treatment program in rural Haiti, made a prediction: “This is the summer when everything will change.” After nearly a week of intensive conference discussion about the global imperative to bring antiretroviral treatment to developing countries, his message couldn’t have been more clear.

As it turned out, Dr. Farmer was right. In the past two years, broadening access to antiretroviral treatment has taken center stage in global HIV/AIDS efforts. Health experts, activists, researchers, government and community leaders, and programmers are now committed to a future where even the poorest countries—which have 90 percent of the world’s HIV infection—will be able to offer life-saving AIDS medications to their citizens, a prospect unthinkable even a few years ago.

What has turned the once-unthinkable into reality was a historic combination of advances in drug formulation, dramatically lower costs, ambitious funding mechanisms, and new political will. While only a few years ago, AIDS patients on highly active antiretroviral therapy (HAART) had to juggle complex regimens of dozens of pills a day, treatment has been simplified to—in some cases—as few as two daily pills, not only less expensive but much easier to follow. The cost of standard antiretroviral medications has dropped precipitously, and the development of inexpensive generic versions holds the promise of even greater affordability. Governments, donors, and the public health community, encouraged by these changes, are showing a renewed energy and commitment to treatment. As funding becomes available through the Global Fund to Fight AIDS, Tuberculosis, and Malaria, President Bush’s Emergency Plan for AIDS Relief, and the WHO campaign to treat 3 million by 2005 (the “3 by 5 initiative”), treatment programs are rapidly being implemented in some of the poorest regions of the world—regions hit hard by AIDS.

Given the rapid pace of these developments and their potential for saving millions of lives, operations research has become critically important. Understanding how to design these new programs so that they are acceptable, functional, accessible, and cost-effective is key to their success. For example, making sure that patients adhere to their medication schedules—in other words, take all of their medication correctly and on time, every day for the rest of their lives—is essential to avoiding viral resistance and the development of deadly new HIV strains that make standard drugs ineffectual. Reducing stigma and discrimination—fear of which can prevent individuals from getting an HIV test and, if positive, from seeking treatment and support services—is also critically important. Promoting safer sex behaviors among HIV-positive individuals can help them avoid infecting others and re-infecting themselves.

Working with research and program partners around the world, the Horizons Program has launched a broad portfolio of operations research to increase global knowledge about implementation of HIV/AIDS treatment programs in sub-Saharan Africa, Asia, and Latin America. This issue of Horizons Report describes operations research in Thailand—which has an established HAART program—and Kenya, where treatment programs are still in their infancy. Critical treatment issues—adherence, protective behavior, monitoring and follow-up, and more—are a focus, as well as the research approaches needed to better understand how to solve treatment-related problems.

Thailand’s Access to Care Program

In 2000, Thailand became one of the first developing nations in the world to provide HIV-positive citizens with HAART. The Access to Care (ATC) program—which began with only 1,200 clients—now serves tens of thousands throughout the country, with plans for ongoing expansion until all Thais who need treatment are covered.

Using operations research to design treatment programs that are acceptable, functional, accessible, and cost-effective is key to their success.

To advise the Thai government as it prepares to further scale the program up, the Community Medicine Department of Chiang Mai University and the Ministry of Public Health conducted a rapid Situation Analysis of the program six months after its inception in the five northern provinces of Chiang Mai, Chiang Rai, Lampang, Lampoon, and Phayao, where HIV prevalence is among the highest in Thailand. With financial and technical support from Horizons, which is funded by the U.S. Agency for International Development, a research team examined operational issues in each province at one large provincial hospital and two district hospitals housing ATC treatment clinics, each serving anywhere between five and 50 clients.

A Situation Analysis assesses the capacity of a health system to deliver services. The researchers concentrated on delivery and logistics, the technical capacity of service providers, the quality and coverage of counseling services, follow-up and monitoring, patterns of client adherence to the drug regime, and the involvement of support groups for HIV-positive people, community-based organizations, and NGOs.

One hundred clients receiving treatment and 33 family caregivers were interviewed for the study; one client/service provider interaction was also observed at each of the 15 clinics. In addition, the team interviewed 20 clients from nine clinics who had dropped out of the program. To gain the perspectives of service providers, researchers interviewed five counselors, nine doctors, eighteen nurses, ten pharmacists, five hospital directors, eight NGO representatives, and one provincial health officer.

Capacity of Care Providers

To prepare care providers—doctors, nurses, pharmacists, and counselors—for the start of the ATC program, the Thai Ministry of Public Health sponsored two days of training. Physicians and pharmacists received guidelines on the medications they were to dispense, while nurses and counselors (the latter for the provincial hospitals only) were trained in how to prepare patients to receive HAART. After the first six months of the program, care providers attended a second meeting, where a counseling manual was distributed.

Map of Thailand The research team analyzed staff capacity by examining job responsibilities, technical competence, confidence to do their job, experience, and attitudes throughout three stages of treatment: preparation (before clients received HAART), the first month of the drug regimen, and the months of treatment following the first month.

Most of the health providers surveyed—95 percent—had positive attitudes about the ATC program overall, citing the value of its services to clients and their improved health as a result of receiving HAART. Yet 76 percent felt that their workload had increased since the program began, although most acknowledged that the problem could be resolved by adjusting their schedules to allow them to concentrate more on the ATC program.

“As professionals dedicated to healing, most are very enthusiastic about working with ATC clients,” said Dr. Simon Baker, Horizons/Population Council, a principal investigator. “They have seen people who were about to die join the program and make a remarkable recovery, so they feel these drugs are making a world of difference.”

Despite their enthusiasm for the program, the providers faced a number of obstacles. During the first month of HAART, more than half of the ATC clients interviewed had adverse side effects, and about half of the doctors and pharmacists and a third of the nurses reported that they did not feel confident about managing side effects.

After the first month, the occurrence of side effects decreased and the health of clients began to improve. Yet one-third of care providers, particularly nurses and pharmacists, reported difficulties in interpreting lab results. Nurses and counselors also reported difficulties in managing the increasing dropout rate during this stage and in motivating clients to continue their medication.

Counseling Roles

Counseling was available at all 15 of the ATC clinics in the study, covering four basic topics: taking medications, recognizing and managing side effects, general health, and safer sex behaviors. While only the five provincial hospitals had trained counselors, all ATC nurses had received training in counseling and provided most of the counseling at the ten district hospitals.

During the preparation phase, nine of 12 hospitals reported that they provided clients with counseling or information two weeks before starting HAART; the other three hospitals started this on the same day that clients began their treatment. Counseling during this phase lasted an average of 26 minutes for individual counseling and 40 minutes for group counseling.

But confidence in providing individual counseling varied by topic and type of health provider. About two-thirds of the nurses, counselors, and pharmacists involved in counseling felt very confident about providing general health counseling. But nearly half did not feel confident about providing safer sex counseling. While 70 percent of pharmacists expressed confidence about counseling patients about the side effects of antiretroviral drugs, only a third of the nurses and none of the counselors did.

Over the course of the first month of treatment, counselors played less of a role than did nurses and pharmacists, largely because the focus of counseling shifted to discussing reactions to the medications and difficulties with adherence. After the first month of treatment, care providers reported that far fewer clients needed counseling because many had worked out problems with dosages and side effects. By this stage, professional counselors had generally stopped working directly with clients; nurses and pharmacists were responsible for most of the counseling.

Quality of Counseling

The researchers also assessed the quality of counseling by observing one-on-one counseling sessions between clients and doctors, nurses, and pharmacists that took place after the preparation stage. These were generally quite short, seven minutes on average. In two-thirds of the observations, service providers started the session by asking clients about problems they were having, but the researchers found that few attempted to draw out details of these problems or to provide information. Care providers tended to ask questions that required simple yes/no answers, and if the client was not forthcoming, the discussion ended quickly. Researchers noted that little effort was made to motivate clients to continue to adhere to medication.

The experience was quite different during a group counseling session observed in a provincial hospital moderated by an NGO representative that focused on the practical problems clients face when taking antiretrovirals. With the help of a nurse, a health worker, and a pharmacist, who each contributed to the discussion from the perspective of their expertise, the two-hour session examined issues and problems in considerable detail, and the clients appeared comfortable about discussing their feelings with the group.

Despite the inconsistency in quality of counseling observed by the research team, an overwhelmingly high percentage of clients expressed satisfaction with all of the counseling services—both one-on-one and group—that they had received. Nearly all of the clients (98 percent) felt that they had had an opportunity to talk about their problems, and 95 percent expressed satisfaction that their problems had been solved.

“One important cultural factor to consider when analyzing quality of counseling is that Thais do not have the same tradition of counseling found in Western nations, or even a strong understanding of the concept,” said Dr. Baker. “Health providers often ‘talk at’ clients or provide information rather than engage in an interactive discussion of personal issues that is key to good counseling.”

Supporting Adherence

To encourage adherence to HAART, the ATC program implemented follow-up procedures—including letter or phone reminders and home visits—to help clients follow medication regimens and remember clinic appointments. But less than half of current clients and dropouts reported that they had been reminded by letter or phone call of an upcoming appointment.

Nearly half of nurses, counselors, and pharmacists did not feel confident about providing safer sex counseling.

The rate of home visits was quite low. Among clients receiving HAART, 20 percent reported that a health care provider visited them at home in the first month of starting HAART, and 11 percent reported that a volunteer from a support organization for HIV-positive people had visited them. After the first month, home visit rates for clients dropped to 5 percent. Among treatment dropouts, the home visit rate was 30 percent for the first month and 25 percent after the first month, higher percentages that likely reflect the greater problems experienced by dropouts.

The researchers also found several patterns of nonadherence to HAART that included missing tablets (13 percent had missed a tablet within the last four days), not taking the medication on time (28 percent), and not following instructions (25 percent). Clients reported different reasons for their nonadherence. “Busy with other things” and “away from home” were the major reasons ATC clients gave for forgetting to take medication.

Overall, ATC client records revealed a high dropout rate of 30 percent after six months among all of the hospitals in northern Thailand. The primary cause for this was the severity of side effects that clients experienced. Among clients interviewed in this study who were receiving HAART, 15 percent reported severe side effects and 43 percent reported moderate side effects in the first month. Among dropouts, though, the rate of severe side effects in the first month was 40 percent and of moderate side effects was 20 percent. After the first month, none of the clients who adhered to HAART reported severe side effects, compared to 29 percent of those who dropped out.

Clients who adhered to their HAART regimen reported marked improvements in their health. Ninety-seven percent reported improved physical health, while 90 and 96 percent reported that their mental health and general outlook on life, respectively, had improved. In addition, 78 percent said that their ability to work had also improved.

Community Involvement

All 15 hospitals in the study had support groups for clients. Ten of the hospitals included representatives of groups for HIV-positive people in establishing selection criteria for clients to receive HAART. At eight hospitals, organizations of people living with HIV/AIDS helped follow up HAART clients; eight hospitals also invited HIV-positive individuals to talk about their own HAART experiences to those starting therapy. People living with HIV/AIDS also undertook home visits, as requested, but this was informally arranged. During these visits, they provided physical and emotional support, offered information on taking medication, encouraged clients to adhere to their medication schedules, and made referrals to other services. Half of the representatives of organizations for HIV-positive people surveyed for the Situation Analysis reported that they had received training in antiretroviral medication from international NGOs.

Fifteen representatives of support organizations for HIV-positive people were interviewed for the study, and several made suggestions about how to improve the ATC program. These included strengthening procedures for follow-up and for home visits, giving organizations of people living with HIV/AIDS a more active role in client monitoring and follow-up, and offering them more training in counseling and health education.

Most health providers agreed that members of these organizations could play an important role in monitoring patients’ medication adherence at home, and also felt that they should moderate group counseling sessions because they understand what clients are experiencing as they begin and continue HAART treatment.

The study also found that NGOs involved in HIV/AIDS treatment, care, and support provided a wide range of services to ATC clients. During home visits, NGO outreach workers provided physical and mental support and health care education, made referrals, and accompanied clients who were unable to get to health care facilities by themselves. They sometimes also provided education and counseling on taking antiretroviral medication. Some of the NGOs were involved in strengthening the capacity of HIV-positive volunteers to undertake outreach activities and provided technical and financial assistance to newly established groups of people living with HIV/AIDS.

Next Steps

According to Dr. Baker, the Situation Analysis has been well received by ATC program managers and public health officials in Thailand, who have used its findings to consider how to improve provider skills and confidence; patient counseling, monitoring, and follow-up; and involvement of local resources to strengthen adherence to HAART and reduce the dropout rate.

“The study has been a useful tool to help health officials in northern Thailand identify where they need to put resources and energy to make ATC even better,” he said. “Even program managers whose clinics were not involved in the study are familiar with the study’s results and use them to advocate for improvement.”

With support from the Ministry of Health and hospital officials, Horizons and its study partners have used the insights gained from the Situation Analysis to design an intervention study. The research evaluates the use of practical guidelines and a strengthened clinic counseling intervention with and without a peer-based component to reduce dropout rates and promote short- and long-term HAART adherence.

“The study has been a useful tool to help health officials identify where they need to put resources and energy.”

To date, health providers have been trained to provide HAART counseling and to use practical guidelines detailing how to provide antiretroviral medication, and HIV-positive volunteers have been trained to provide peer education to individuals taking these medications. In Chiang Mai, Chiang Rai, Lampang, and Lampoon provinces, 45 hospitals have been assigned to one of three study arms. In Arm 1, the health providers will provide HAART counseling and use the practical guidelines. Arm 2 will be the same as Arm 1, except that HIV-positive volunteers will provide peer education, counseling, and support at the hospital and at clients’ homes. Arm 3, the control arm, will provide the standard of care that is currently offered in the ATC program. Findings from this research will be used to help strengthen and scale up the ATC program throughout Thailand.
