Abstract
With a 19.2% HIV prevalence, South Africa has the largest HIV/AIDS epidemic worldwide. Despite a recent scale-up of public sector HIV resources, including community-based programs to expand HIV care, suboptimal rates of antiretroviral therapy (ART) initiation and adherence persist. As community stakeholders with basic healthcare training, community health workers (CHWs) are uniquely positioned to provide healthcare and insight into potential strategies to improve HIV treatment outcomes. The study goal was to qualitatively explore the self-perceived role of the CHW, unmet CHW needs, and strategies to improve HIV care in rural KwaZulu-Natal, South Africa. Focus groups were conducted in May–August 2014, with 21 CHWs working in Msinga subdistrict. Interviews were audio-recorded, transcribed, and translated from Zulu into English. A hybrid deductive and inductive analytical method borrowed from grounded theory was applied to identify emergent themes. CHWs felt they substantially contributed to HIV care provision but were inadequately supported by the healthcare system. CHWs' recommendations included: (1) sufficiently equipping CHWs to provide education, counseling, social support, routine antiretroviral medication, and basic emergency care, (2) modifying clinical practice to provide less stigmatizing, more patient-centered care, (3) collaborating with traditional healers and church leaders to reduce competition with ART and provide more holistic care, and (4) offsetting socioeconomic barriers to HIV care. In conclusion, CHWs can serve as resources when designing and implementing interventions to improve HIV care. As HIV/AIDS policy and practice evolves in South Africa, it will be important to recognize and formally expand CHWs' roles supporting the healthcare system.
Introduction
I
Despite these successes, only 42% of people living with HIV were on ART as of 2013, 7 –15 and at least one-third of all deaths in South Africa can still be attributed to AIDS. 3 Studies reveal unnecessary delays in ART initiation 7,10,16 and also an increasing likelihood that a patient will default as time passes. 17 Barriers to linkage to and retention in HIV care include denial, stigma, insufficient patient education, poor social support, socioeconomic limitations including transportation issues, fear of long-term therapy and its side effects, and lack of efficiency and accessibility within the healthcare system. 7,8,10 –12,14,18 –22 However, research on strategies to improve linkage to and retention in ART in sub-Saharan Africa remains limited. 23
In the setting of an already overburdened and rapidly expanding healthcare system, one component of the aforementioned scale-up has been the increasing use of community health workers (CHWs). The umbrella term “community health worker” was proposed in 1989 by a World Health Organization Study Group to describe a variety of community health aides who have “shorter training than professional workers,” are “supported by the health system but not necessarily a part of its organization,” are “members of the communities where they work,” “selected by the communities,” and “answerable to the communities for their activities.” 24 As community stakeholders with basic healthcare training, CHWs act as human resources, bridging their communities with the world of evidence-based medicine. 25 Strong evidence supports using community-based interventions to strengthen health services such as HIV/AIDS, tuberculosis (TB), and maternal and child health. 5,26 –30 Recent systematic reviews demonstrate that treatment outcomes among patients primarily receiving care from CHWs or nurses are comparable to outcomes among patients cared for by doctors. 31,32 In addition, CHW systems are cost-effective and rapidly scalable units of the healthcare system. 33
In South Africa, CHWs, also known as community caregivers or home-based caregivers, have been employed by NGOs and the Department of Health for the duration of the HIV/AIDS epidemic. The CHW role varies depending on the community's healthcare needs; they most commonly serve as educators and mediators between patients with HIV or TB and the formal healthcare system. 25,34 However, CHWs often take on a larger role that is underappreciated and unrecognized, 35 making it difficult to identify approaches for improving CHW effectiveness. Thus far, research on the inner workings of CHW systems has been sparse, 25,36 but it is urgently needed to ensure appropriate and sustainable implementation of community-based interventions across sub-Saharan Africa. 33
The CHW perspective is valuable, as it encompasses both patient and healthcare provider perspectives. By means of CHWs' frequent contact with patients in their home environments, CHWs are privy to information that patients do not share with healthcare providers in the formal clinic setting. CHWs also directly witness—and attempt to mitigate—patients' daily challenges. Thus, CHWs are uniquely positioned to provide insight into potential strategies to systematically improve HIV care and overall health outcomes. They are also the individuals who are best situated to elucidate the resources that CHWs need to provide and expand community-based care to better meet patients' needs. The goal of this qualitative study was to describe the self-perceived role of the CHW, identify unmet needs that prevent CHWs from fulfilling this role, and explore recommended strategies for addressing barriers to the provision of optimal HIV care.
Methods
Setting
Approximately 180,000 traditional Zulu people live in the rural, resource-limited Msinga subdistrict 37 of the KwaZulu-Natal Province of South Africa. This province, where 37.4% of pregnant women are infected with HIV, has the highest HIV prevalence in the world. 38 Healthcare in Msinga is provided by a 350-bed district government hospital, 16 satellite primary healthcare clinics, and a local NGO.
Participant recruitment and informed consent
Twenty-one CHWs with ≥2 years of experience working in Msinga were recruited by phone for participation in one of three focus groups. 21 To provide a sample with broad geographic representation of the Msinga neighborhoods, these participants were purposively selected from a list of all 51 CHWs working for the aforementioned local NGO's home-based care branch. 21 Since it was founded in 1999, this NGO has been employing CHWs for community outreach, with a particular focus on HIV/AIDS. Thus, the CHWs interviewed represent a convenience sample. Participants gave written informed consent allowing focus group interviews to be recorded and were reimbursed for travel expenses.
Data collection
In a private conference room, the lead researcher together with a native Zulu-speaking research team member conducted three focus groups, each of 2.5 h duration (seven participants per group). A semi-structured interview guide was used to explore CHWs' perspectives on their roles in their patients' healthcare, ways in which patients can be supported regarding ART and HIV care, challenges that limit CHWs' abilities to support their patients, and potential strategies to address barriers to HIV care. Open-ended questions and probes were used to facilitate open discussion. Audio-recorded interviews were professionally transcribed and translated into English.
Data analysis
Thematic analysis of transcripts was conducted using an established hybrid approach of deductive and inductive coding borrowed from grounded theory. 39 –42 Initially, a codebook was constructed using deductive (theory driven) themes from the literature. Transcripts and notes were reviewed during data collection to detect emerging inductive (data driven) themes and to revise the interview guide as necessary. Using Atlas.ti software, the final coding guide was applied to the entire dataset. Prominent patterns and themes were identified by means of data displays for relevant codes and simple frequencies.
Ethics
This study was approved by institutional review boards at the South African Medical Association (SAMA) in Pretoria, South Africa and Yale University in New Haven, Connecticut.
Results
All 21 CHWs were women, of mean age 44.3 ± 11.7 years, and were working in a cumulative total of 21 neighborhoods served by 12 different clinics. Fourteen had ≥10 years of experience working as CHWs.
CHWs' roles and unmet needs
CHWs' main roles included providing a consistent, long-term source of education, counseling, and treatment support for patients and their families, and facilitating linkages to healthcare and social services. This involved helping patients to understand the role of ART in their lives, facilitating evolving motivations for treatment adherence over time, and combating pill fatigue (Table 1, Quotes 1–3). For example, patients who initially began ART due to fear of dying and then subsequently recovered found themselves needing to focus on new reasons for remaining on treatment. Some patients noticed their improving physical health, including trends in viral loads and CD4 counts, and decided they were cured or had reached a state of health where it would now be safe to skip ART doses (Table 1, Quote 4).
CHW, community health worker.
CHWs worked to encourage ART initiation and adherence by continually reinforcing the education that patients received during HIV/ART counseling and literacy classes. Furthermore, CHWs felt they could address denial by repeatedly visiting patients at home and carefully educating them together with their families on general health issues, including, but not limited to, HIV. Through this type of sustained interaction, some patients and family members who initially refused to believe in the existence of HIV as a disease eventually came to terms with their HIV diagnosis and accepted the necessity of taking ART (Table 1, Quotes 5 and 6). For patients who were concerned about ART side effects or were struggling to reconcile the idea of evidence-based ART with their traditional belief systems, ongoing support and counseling from CHWs and family members, especially after the literacy classes at the healthcare facility had ended, was crucial for successful ART initiation and adherence. For patients choosing not to disclose their HIV status to partners or family members, their CHWs were the only community members positioned to reinforce their ART adherence and monitor their disease progression.
Due to their reluctance to leave clinically deteriorating patients to fend for themselves, CHWs often found themselves providing food for patients or collecting ART on their behalf in ways that extended beyond their scope of work (Table 1, Quotes 7–9). For this reason, CHWs called for stronger support from their supervisors and other members of their CHW networks, including more consistent patient follow-up from social workers (Table 1, Quote 10). CHWs also frequently had to intervene during extenuating circumstances such as life-threatening illness or childbirth when the ambulance's arrival was delayed. Thus, CHWs requested access to supplies, particularly gloves, for personal and patient protection against infection (Table 1, Quotes 11 and 12). CHWs also expressed a need for clinic-issued badges or nametags that would formalize their roles in the healthcare system, thus enabling them to advocate for patients at clinics, hospitals, and police stations (e.g., when patients needed to obtain legal documents to facilitate their healthcare) (Table 1, Quotes 13 and 14).
Recommended strategies to improve ART initiation and adherence
Reducing stigma from healthcare providers and family members through education
To minimize the patient experience of stigma and isolation, CHWs suggested that medical staff discontinue stigmatizing practices such as dividing patients into separate waiting areas based on HIV status or using hand gestures to indicate a patient's status (Table 2, Quotes 1–3). Healthcare staff should be reminded that, despite the high prevalence of HIV in this region, a diagnosis of HIV is never routine for the individual patient and always requires thorough pre- and post-test counseling (Table 2, Quote 4).
ART, antiretroviral therapy; CHW, community health worker.
In addition to medical staff training, community awareness and education campaigns were suggested as a way to disseminate knowledge to uninfected family members regarding signs and symptoms of HIV, how ART works and how to use it, and what to do if a family member tests HIV positive. Overall, this strategy would potentially reduce stigma both in the community and at home by helping community members to appreciate HIV as a medical illness and to become more supportive of patients taking ART.
Reducing competition by collaborating with alternative medicine providers and establishing HIV/ART community support groups
CHWs advised their patients not to take traditional herbs concurrently with their ART because of their potentially dangerous side effects and the lack of knowledge about possible drug interactions with ART. For example, patients amenable to taking ART would likely have difficulty doing so if they simultaneously used herbal remedies that caused nausea and vomiting (Table 2, Quote 1). Nevertheless, CHWs reported that many patients demonstrate unwavering faith in traditional healing and religion, in which case discouraging the use of herbal remedies or prayer could conceivably erode patients' trust in the healthcare system (Table 2, Quotes 2 and 3). To better reach this patient population and reduce competition-related barriers to patients' linkage to and retention in ART, CHWs suggested that the healthcare system join forces with traditional healers and religious leaders through education and collaboration (Table 2, Quote 4 and 5). Cooperation between traditional and formal healthcare systems would be attractive to patients and likely to positively impact their engagement in care and adherence to treatment.
CHWs also felt that education campaigns could help patients living in communities with strong traditional influence begin to recognize their HIV-related symptoms as having a biomedical, as opposed to spiritual, origin (Table 2, Quote 6). Given the positive and empowering impact of social networks, community-based patient support groups, where patients can actively observe the health benefits of ART in their peers with HIV, were suggested to reduce community stigma and encourage patients to initiate ART (Table 2, Quote 7). It was noted, however, that these interventions would need to be sensitively designed to encourage sufficient participation from these stigmatized patients.
Reducing transportation barriers to healthcare access
CHWs expressed an urgent need to find alternative ways to help patients obtain their medications and access emergency care (Table 2, Quote 1). One suggestion was the designation of a nonemergency vehicle that would be used to support home-based care services for patients who intermittently need help with ART collection and transportation to the hospital (Table 2, Quotes 2–4). In addition, designating community halls or other physical structures to be used as shelters for ART collection during bad weather might allow mobile clinic units to continue distributing ART to patients living in areas only serviced by mobile clinic units. Finally, patients from rural areas frequently moved to bigger cities for temporary employment, which required them to transfer care to their new local clinic. CHWs felt that the transfer-of-care referral process was complicated, inconvenient, and confusing for many patients (and even CHWs), and they recommended simplifying or streamlining the process to improve retention rates among mobile patients (Table 2, Quote 5).
Promoting patient-centered care by mitigating food insecurity and triaging patients based on socioeconomic and medical need
CHWs consistently found themselves defending the formal healthcare system to patients to counteract dissatisfaction due to long wait times and negative interactions with healthcare staff (Table 2, Quotes 1 and 2). Since low socioeconomic status frequently limited patients' abilities to access healthcare and remain adherent to treatment, CHWs strongly recommended a triaging system to help clinic staff become more attentive to particularly resource-limited or “high-risk” patients (Table 2, Quotes 3–7). Such patients' hospital and clinic visits were typically rare, invaluable opportunities to enable ART initiation and adherence as well as pivotal moments in patients' lives where dissatisfaction might lead them to choose traditional healing over ART.
CHWs reported that patients were notably more receptive to healthcare staff when food parcels were provided during home-based care visits; patients seemed to feel that this gesture was a sign that their struggles were being acknowledged and that providers cared about their overall well-being (Table 2, Quotes 8 and 9). Provision of food parcels or social welfare grants to reward patients who initiate, regularly take their ART, and achieve viral suppression would encourage adherence while simultaneously helping to strengthen patient–provider relationships and address food insecurity.
Discussion
People with HIV in sub-Saharan Africa report a need for support ranging from “instrumental” support (i.e., material, medical, and financial assistance) to informational and emotional support. 21,43 CHWs serve a key role in HIV-related care by providing a consistent source of home-based HIV/ART education, counseling, and support for patients and family members. By building relationships with patients over time, CHWs can effectively mitigate barriers to care such as stigma, denial, inadequate patient education, and poor social support. 25 Evidence also suggests that patients would benefit from the formal expansion of CHW roles to include patient support group activities 44,45 and collaborative partnerships with traditional healers. 46,47 This is consistent with studies from Mozambique and Lesotho showing that there is an unmet patient need for health-related social support 43 and suggesting that this need can be met, at least in part, by CHWs. 36 Beyond the scope of the CHW role, CHWs spoke to a need for the expansion of government assistance programs to reduce socioeconomic barriers to care and for modifications to routine clinical practice to provide less stigmatizing, more patient-centered care. These recommended strategies target barriers to care for the individual patient as well as the broader social drivers of HIV/AIDS described in formerly published frameworks for HIV prevention and treatment such as Auerbach's socio-economical model. 48,49
Through longitudinal education and counseling, CHWs are uniquely positioned to intervene at points in the HIV care continuum highly susceptible to attrition. 25,50 Emerging evidence suggests that counseling can be adapted to facilitate rapid ART initiation in a way that reduces pre-ART loss to follow-up without later compromising patient adherence. 51 To support this type of intervention, CHW training should include enhanced HIV/ART education and counseling skills. 52 Closer working relationships with clinic staff, nurses, and social workers, for example, would fortify CHWs' skills and also provide opportunities to obtain guidance on managing difficult patients. Although in Mozambique patients most often receive informational and emotional support from family or friends, as opposed to healthcare staff, 43 these types of support may be especially effective when provided by CHWs. Specifically, CHWs' community membership may make them more approachable to patients while their working relationship with the healthcare system provides them with a level of healthcare knowledge and ability to navigate the system that surpasses the average community member.
CHW programs must be sufficiently structured and monitored to prevent challenges that many such programs have faced in the past, namely unmanageable workloads, lack of clear scope of work, insufficient supervision, lack of accountability, inadequate resources to effectively perform their assigned tasks, and lack of recognition from official healthcare providers. 53 In South Africa, the current CHW role does not formally include responsibilities such as providing extended home-based care for physically weak or socially isolated patients, helping with logistical issues such as transportation to a healthcare facility, collecting medications, and assisting with childbirth while waiting for an ambulance. Nevertheless, CHWs feel compelled to act in these capacities, because it is clear to them that providing these services improves patient outcomes and, in their absence, patients will suffer. The extent of the CHW role must be recognized so that CHWs can be appropriately trained and equipped to engage in such activities. 53,54 Deployment of CHWs without the supplies and resources they require to accomplish tasks is unproductive, discouraging to CHWs, and detrimental to CHW credibility, 53 and it exposes CHWs to unnecessary risk. Failure to define their scope of work also creates risk of unmanageable workloads and demands that compete with their primary responsibilities. 55
Engaging medically stable patients in community support groups, or “community-based adherence clubs”, is a promising and low-cost strategy for improving HIV care, particularly retention in ART. Often facilitated by CHWs, such groups can provide support within the community, reduce challenges associated with denial and stigma, and reduce the frequency of patient visits, thus minimizing congestion at local clinics. 44 A 2015 study in urban Cape Town demonstrated that patients engaged in adherence clubs had significantly lower viral loads and higher CD4 counts after 4 and 12 months on ART compared with patients managed at primary care facilities. 45 This type of group intervention could be adapted for use in rural South Africa and facilitated on a monthly basis by experienced CHWs selected by their local clinics or communities.
Several studies have recognized the influence of traditional belief systems on ART success and the need for integrated healthcare services. 46,47 Consistent with our findings, at least one study in KwaZulu-Natal has demonstrated that the use of traditional medicine is associated with nonadherence to ART. 47 Healthcare providers and CHWs often express a mistrust toward traditional healers, yet they play an important role in Zulu and African culture and society. 46 Indeed, some traditional healers perceive themselves as having a complementary role in HIV care and do not necessarily view their remedies as substitutes for ART. 46 Neglecting to directly address the use of alternative medicine and the role of traditional healers in HIV care undermines patients' trust in the formal healthcare system and represents a missed opportunity to engage patients in the HIV care continuum through patient-centered, holistic medical care. Patient education in clinics and communities should address the controversial issue of religion and traditional healing and strategies for safely combining ART with traditional remedies so as to minimize medication interactions. CHWs recommended negotiation skill training for healthcare providers to help address patients' preferences for alternative therapies. CHWs can also support healthcare providers by brokering relationships between patients, healthcare providers, religious leaders, and traditional healers.
The need for improvements in clinical practice, particularly better patient–provider relations and systematized patient care engagement and follow-up, has emerged in other South African studies. 21,56 –59 Acknowledging the limitations of an overburdened healthcare system, staff training should be designed to encourage the provision of destigmatized, patient-centered care and to ensure adequate patient counseling at time of diagnosis. 50 There is also growing evidence supporting the need to improve access to HIV care by addressing a patient's socioeconomic circumstances. 21,48,60 Food insecurity 60,61 and transportation costs 62 are common barriers to the maintenance of chronic medications and the receipt of emergency healthcare; loss to follow-up from ART is essentially unavoidable for patients without the financial means to reach the clinic to regularly collect medications. 60,62 Given long clinic waiting times that may require patients to return the next day, combined with CHWs' reports of patients becoming acutely ill and dying at home for lack of means to reach a healthcare facility, government systems need to develop methods for assisting patients who present to the clinic appearing particularly ill or socioeconomically destitute.
CHWs in this study also offered several tangible strategies to directly mitigate socioeconomic strain, thereby contributing to the limited research on interventions to address financial barriers. 63 To ameliorate the burden of transportation costs and improve access to both urgent and routine care, CHWs suggested strengthening the ambulance system and devising alternative ways to distribute ART to patients for whom financial limitations are a major barrier. To further offset socioeconomic barriers to care, CHWs suggested the use of stipends and cash transfers, which have been effective at improving linkage to care and reducing loss to follow-up in countries such as Tanzania and Uganda. 64 Previously, in South Africa, patients with low CD4 counts could obtain disability grants, 65 but this practice was formally discontinued because of concerns, without clear evidence, 65 that patients were intentionally not taking ART to keep their CD4 low and thus remain eligible for disability. 66,67 Thus, government disability grants could be reframed to reward monthly ART collection or viral suppression and potentially re-categorized as chronic illness, basic income, or unemployment grants. Financial incentives, while logistically challenging to implement, may be more effective at encouraging engagement in care than merely subsidizing transportation costs and may also increase household and family support for ART.
The main limitation of this study was the lack of data triangulation. However, by design, this study was meant to focus on CHWs' unique experiences and allow for their meaningful self-reflection. Also, due to the qualitative nature of this work, our findings may not be generalizable beyond KwaZulu-Natal, South Africa. Despite these limitations, the synthesis of our findings with other recent studies lays the groundwork for several salient, practical, and potentially low-cost interventions to improve HIV-related healthcare in rural South Africa.
In summary, CHWs support HIV-related healthcare provision but feel that their role is unrecognized and, consequently, inadequately supported by the healthcare system. Their suggestions for improving HIV care include acknowledging and expanding CHWs' roles, and sufficiently training them to provide services, including education, counseling, social support, home- and community-based ART distribution, and basic emergency medical care. Clinic and hospital staff would benefit from additional training to reduce stigma, negative patient–provider interactions, and the perception of competition with alternative medicine. CHWs can also work more closely with healthcare staff and traditional healers to facilitate the provision of more patient-centered and holistic medical care. Finally, several strategies for reducing socioeconomic strain and disease-related disability were provided. Moving forward, policymakers may benefit from recognizing and expanding CHWs' roles supporting the healthcare system as well as obtaining feedback from CHWs regarding interventions to improve HIV care.
