HIV knowledge and health-seeking behavior in Zambézia Province, Mozambique

BOHEMIA a cluster randomized trial to assess the impact of an endectocide-based one health approach to malaria in Mozambique: baseline demographics and key malaria indicators

BACKGROUND

Many geographical areas of sub-Saharan Africa, especially in rural settings, lack complete and up-to-date demographic data, posing a challenge for implementation and evaluation of public health interventions and carrying out large-scale health research. A demographic survey was completed in Mopeia district, located in the Zambezia province in Mozambique, to inform the Broad One Health Endectocide-based Malaria Intervention in Africa (BOHEMIA) cluster randomized clinical trial, which tested ivermectin mass drug administration to humans and/or livestock as a potential novel strategy to decrease malaria transmission.

METHODS

The demographic survey was a prospective descriptive study, which collected data of all the households in the district that accepted to participate. Households were mapped through geolocation and identified with a unique identification number. Basic demographic data of the household members was collected and each person received a permanent identification number for the study.

RESULTS

25,550 households were mapped and underwent the demographic survey, and 131,818 individuals were registered in the district. The average household size was 5 members and 76.9% of households identified a male household head. Housing conditions are often substandard with low access to improved water systems and electricity. The reported coverage of malaria interventions was 71.1% for indoor residual spraying and 54.1% for universal coverage of long-lasting insecticidal nets. The median age of the population was 15 years old. There were 910 deaths in the previous 12 months reported, and 43.9% were of children less than 5 years of age.

CONCLUSIONS

The study showed that the district had good coverage of vector control tools against malaria but sub-optimal living conditions and poor access to basic services. The majority of households are led by males and Mopeia Sede/Cuacua is the most populated locality in the district. The population of Mopeia is young (< 15 years) and there is a high childhood mortality. The results of this survey were crucial as they provided the household and population profiles and allowed the design and implementation of the cluster randomized clinical trial. Trial registration NCT04966702.

"If it weren't for my traditional healer, I would be dead": Engaging traditional healers to support people living with HIV in rural Mozambique

Across rural sub-Saharan Africa, people living with HIV (PLHIV) commonly seek out treatment from traditional healers. We report on the clinical outcomes of a community health worker intervention adapted for traditional healers with insight into our results from qualitative interviews. We employed a pre-post intervention study design and used sequential mixed methods to assess the impact of a traditional healer support worker intervention in Zambézia province, Mozambique. After receiving a positive test result, 276 participants who were newly enrolled in HIV treatment and were interested in receiving home-based support from a traditional healer were recruited into the study. Those who enrolled from February 2016 to August 2016 received standard of care services, while those who enrolled from June 2017 to May 2018 received support from a traditional healer. We conducted interviews among healers and participants to gain insight into fidelity of study activities, barriers to support, and program improvement. Medication possession ratio at home (based on pharmacy pick-up dates) was not significantly different between pre- and post-intervention participants (0.80 in the pre-intervention group compared to 0.79 in the post-intervention group; p = 0.96). Participants reported receiving educational and psychosocial support from healers. Healers adapted their support protocol to initiate directly observed therapy among participants with poor adherence. Traditional healers can provide community-based psychosocial support, education, directly observed therapy, and disclosure assistance for PLHIV. Multiple factors may hinder patients' desire and ability to remain adherent to treatment, including poverty, confusion about medication side effects, and frustration with wait times at the health facility.

Barriers and facilitators to antiretroviral adherence and retention in HIV care among people living with HIV in the Comarca Ngäbe-Buglé, Panama

Introduction

Panama’s HIV epidemic is far from under control. One of the populations with the fastest-growing epidemic among the Indigenous peoples of the Comarca Ngäbe-Buglé (CNB). The CNB is an administratively autonomous Indigenous region in Western Panama that is home to over 200,000 individuals of Ngäbe and Buglé ethnicities. This population is unique and, in several ways, represents the early stages of the AIDS epidemics in high-income countries. The CNB is the most impoverished region in Panama and is relatively isolated from outside influences, with limited roads, electricity, and an internet connection, including medical assistance. Around 1.5% of all rapid HIV tests are positive, compared to a national prevalence of 0.9%; in CNB, diagnosis tends to be late. In CNB, 56.3% of individuals had an initial CD4 count of <350 cells/mm3. Antiretroviral treatment (ART) dropout in this region is five times higher than the national average; there is high early mortality due to opportunistic infections. Using the Social-Ecological Theory for Health as a framework, this study aims to describe the facilitators and barriers associated with ART adherence and retention in HIV care among people living with HIV (PLHIV) in the CNB. A better understanding of factors that obstruct adherence could lead to more effective HIV care and prevention in CNB.

Methods

We conducted 21 semi-structured interviews with PLHIV who reside across all three regions of the CNB and have attended an antiretroviral (ART) clinic at least once. Deductive thematic analysis was used to uncover themes related ART adherence and retention in HIV care at the individual, social and structural levels.

Discussion

This unique, isolated population of rural Indigenous peoples has high infection rates, late diagnosis, poor ART adherence, and high AIDS-related death rates. The CNB is an important region to examen ART adherence and retention in care. We determined that psychological health, social support, and discrimination acted as individual-level facilitators and barriers to adherence and retention. Notably, structural barriers included difficult access to ART care due to travel costs, ART shortages, and uncooperative Western/Traditional medical systems. Recommended interventions used in other Low- and Middle-Income settings include increasing peer and family-level support and community knowledge and understanding of HIV infection. Additionally, our study suggests structural interventions, including decreasing the cost and distance of traveling to the ART clinic, by decentralizing services, decreasing food scarcity, and increasing collaboration between Western and Traditional providers.

Health-Seeking Behaviors in Mozambique: A Mini-Study of Ethnonursing

In settings where traditional medicine is a crucial part of the healthcare system, providing culturally competent healthcare services is vital to improving patient satisfaction and health outcomes. Therefore, this study sought to gain insight into how cultural beliefs influence health-seeking behaviors (HSBs) among Mozambicans. Participant observation and in-depth interviews (IDIs) were undertaken using the ethnonursing method to investigate beliefs and views that Mozambicans (living in Pemba City) often take into account to meet their health needs. Data were analyzed in accordance with Leininger’s ethnonursing guidelines. Twenty-seven IDIs were carried out with 12 informants from the Makonde and Makuwa tribes. The choice of health service was influenced by perceptions of health and illness through a spiritual lens, belief in supernatural forces, dissatisfaction with and dislike of the public medical system on grounds of having received poor-quality treatment, perceived poor communication skills of health professionals, and trust in the indigenous medical system. This study confirmed the need for health professionals to carefully take cultural influences into consideration when providing care for their patients. We recommend an educational intervention that emphasizes communication skills training for healthcare workers to ensure successful physician/nurse–patient relationships.

How beliefs in traditional healers impact on the use of allopathic medicine: In the case of indigenous snakebite in Eswatini

Snakebite is a major public health problem in Eswatini and serious envenomations can be responsible for considerable morbidity and mortality if not treated correctly. Antivenom should be administered in hospital in case of adverse reactions and any delays due to distance, transport, costs, antivenom availability and cultural beliefs can be critical. Myths and superstition surround snakes, with illness from snakebite considered a supernatural phenomenon best treated by traditional medicine since healers can explore causes through communication with the ancestors. Traditional consultations can cause significant delays and the remedies may cause further complications. Four rural focus group discussions were held in varying geographical regions to establish why people may choose traditional medicine following snakebite. The study revealed four themes, with no apparent gender bias. These were 'beliefs and traditions', 'logistical issues', 'lack of knowledge' and 'parallel systems'. All snakes are feared, regardless of geographical variations in species distribution. Deep-seated cultural beliefs were the most important reason for choosing traditional medicine, the success of which is largely attributed to the 'placebo effect' and positive expectations. Collaboration and integration of the allopathic and traditional systems assisted by the regulation of healers and their methods could improve future treatment success. The plight of victims could be further improved with more education, lower costs and improved allopathic facilities.

Use of herbal remedies in the management of sleeping sickness in four northern provinces of Angola

ETHNOPHARMACOLOGICAL RELEVANCE

This study reports for the first time on the use of folk medicine to treat sleeping sickness and its symptoms in four endemic provinces in northern Angola. By interviewing both traditional practitioners and confirmed patients, it highlights reasons to recourse to folk medicine, the plant species used for this affection as well as arises awareness about the use of particular plants showing potential risks.

AIM OF THE STUDY

The aims of this explorative study were three-fold. Firstly, it informed on access to, and use of plant-based medicine as first-choice treatment by infected persons. Secondly, it aimed at collecting comprehensive data from patients and traditional healers on herbal remedies in order to identify plant species used in the management of the disease. Thirdly, it served as contribution for primary indication of potential risk of use associated with the studied plants and their preparation.

MATERIALS AND METHODS

The study was conducted in 4 endemic provinces of Angola, namely Bengo, Zaire, Kwanza Norte and Uíge. We explored the use of herbal remedies by conducting structured and semi-structured interviews within two distinct study populations. The first group comprises 30 patients who had been diagnosed for trypanosomiasis and treated by the reference treatment. The second group included 9 traditional practitioners who had already treated sleeping sickness. The plants that were cited during the interviews were collected during field walks under supervision of a traditional healer, then authenticated and deposited at the National Herbarium in Luanda.

RESULTS

Of the 30 included patients, 12 (40%) had turned to folk medicine in the management of trypanosomiasis and related symptoms. 7 medicinal plants were reported by this group. Considering the key motivation to consult a traditional practitioner, two main factors accounted for half of the cases: "past experience with folk medicine" and "family habit". Out of 9 traditional practitioners' interviewees, 26 medicinal plants were cited. Roots and leaves were the most used plant parts, and decoction was the common mode of preparation. Evidence for antitrypanosomal activity in the scientific literature was found for 56% (17 of 30) of the identified plant species. The most cited plant was Crossopteryx febrifuga (UR = 6). Some of the cited plants, as for example Aristolochia gigantea, raised concern about potential toxicity.

CONCLUSIONS

With 40% of infected persons having turned first to folk medicine before consulting a medical doctor, this explorative study points out that plant-based medicines play an important role in local dynamics of health care. It highlights the need for primary assessment of potential risk of use related to the herbal recipes, and for reporting it to the concerned population. This first ethnobotanical study on trypanosomiasis in endemic provinces of Angola provides information on 30 plants, of which some had been identified as promising for further pharmacological research. Our results provide a first step towards the validation and valorization of Angolan herbal remedies for sleeping sickness.

Knowledge gaps of STIs in Africa; Systematic review

Sexually Transmitted Infections (STIs) are ambiguous burden of tremendous health, social and economic consequences. The current systematic review was conducted in order to determine awareness and knowledge of Africans toward sexually transmitted infections, not only concerning HIV/AIDS, but also other STIs such as gonorrhea, syphilis, HBV, HCV and HPV. A systematic review of literature was conducted, studies were retrieved and selected after fulfilling the inclusion criteria as well as passing the assessment procedure. Related data was extracted, quantitative analysis was conducted among participants who responded to questions related to HIV, HBV, HCV, HPV or STIs knowledge, sensitivity analysis as well as subgroup analysis were also conducted. Seventy four articles addressing knowledge among 35 African countries were included and 136 questions were analyzed and synthesized. The question "does using condom reduces HIV transmission?" was answered by 1,316,873 Africans in 35 countries, 66.8% [95% Cl; 62.6, 70.9] answered yes. While the question "is sexual contact a possible route of HBV transmission?" was answered by 7,490 participants in 5 countries; 42.5% [95% Cl; 20.4, 64.7] answered yes. The differences observed among populations are highlighting the possibility for improvement by directing light toward specific populations as well as addressing specific awareness knowledge to ensure that the general as well as the related specific preventive knowledge is improved.

Individual factors associated with time to non-adherence to ART pick-up within HIV care and treatment services in three health facilities of Zambézia Province, Mozambique

Introduction

Mozambique has made significant gains in addressing its HIV epidemic, yet adherence to visit schedules remains a challenge. HIV programmatic gains to date could be impaired if adherence and retention to ART remains low. We investigate individual factors associated with non-adherence to ART pick-up in Mozambique.

Methods

This was a retrospective cohort of patients initiating ART between January 2013 and June 2014. Non-adherence to ART pick-up was defined as a delay in pick-up ≥ 15 days. Descriptive statistics were used to calculate socio-demographic and clinical characteristics. Adherence to ART pick-up was assessed using Kaplan Meier estimates. Cox proportional hazards model was used to determine factors associated with non-adherence.

Results

1,413 participants were included (77% female). Median age was 30.4 years. 19% of patients remained adherent to ART pick-up during the evaluation period, while 81% of patients were non-adherent to ART pick-up. Probability of being non-adherent to ART pick-up by 166 days following initiation was 50%. In univariate analysis, being widowed was associated with higher adherence to ART pick-up than other marital status groups (p = 0.01). After adjusting, being ≥35 years (aHR: 0.843, 95% CI: 0.738–0.964, p = 0.012); receiving efavirenz (aHR: 0.932, 95% CI: 0.875–0.992, p = 0.026); and being urban (aHR: 0.754, 95% CI: 0.661–0.861, p<0.0001) were associated with improved adherence. Non-participation in a Community ART Support Group (CASG) was associated with a 43% increased hazard of non-adherence to ART pick-up (aHR 1.431, 1.192–1.717, p<0.0001)

Conclusions

Interventions should focus on the first 6 months following ARV initiation for improvements. Younger persons and widows are two target groups for better understanding facilitators and barriers to visit schedule adherence. Future strategies should explore the benefits of joining CASGs earlier in one´s treatment course. Finally, greater efforts should be made to accelerate the scale-up of viral load capacity and HIV resistance monitoring.

Using the COMMVAC taxonomy to map vaccination communication interventions in Mozambique

BACKGROUND

Improved communication about childhood vaccination is fundamental to increasing vaccine uptake in low-income countries. Mozambique, with 64% of children fully vaccinated, uses a range of communication interventions to promote uptake of childhood immunisation.

OBJECTIVES

Using a taxonomy developed by the 'Communicate to Vaccinate' (COMMVAC) project, the study aims to identify and classify the existing communication interventions for vaccination in Mozambique and to find the gaps.

METHODS

We used a qualitative research approach to identify the range of communication interventions used in Mozambique. In-depth semi-structured interviews were carried out with key purposively selected personnel at national level and relevant documents were collected and analysed. These data were complemented with observations of communication during routine vaccination and campaigns in Nampula province. We used the COMMVAC taxonomy, which organises vaccination communication intervention according to its intended purpose and the population targeted, to map both routine and campaign interventions.

RESULTS

We identified interventions used in campaign and routine vaccination, or in both, fitting five of the seven taxonomy purposes, with informing or educating community members predominating. We did not identify any interventions that aimed to provide support or facilitate decision-making. There were interventions for all main target groups, although fewer for health providers. Overlap occurred: for example, interventions often targeted both parents and community members.

CONCLUSIONS

We consider that the predominant focus on informing and educating community members is appropriate in the Mozambican context, where there is a high level of illiteracy and poor knowledge of the reasons for vaccination. We recommend increasing interventions for health providers, in particular training them in better communication for vaccination. The taxonomy was useful for identifying gaps, but needs to be more user-friendly if it is to be employed as a tool by health service managers.

Mixed methods inquiry into traditional healers' treatment of mental, neurological and substance abuse disorders in rural South Africa

BACKGROUND

Traditional healers are acceptable and highly accessible health practitioners throughout sub-Saharan Africa. Patients in South Africa often seek concurrent traditional and allopathic treatment leading to medical pluralism.

METHODS & FINDINGS

We studied the cause of five traditional illnesses known locally as "Mavabyi ya nhloko" (sickness of the head), by conducting 27 in-depth interviews and 133 surveys with a randomly selected sample of traditional healers living and working in rural, northeastern South Africa. These interviews were carried out to identify treatment practices of mental, neurological, and substance abuse (MNS) disorders. Participating healers were primarily female (77%), older in age (median: 58.0 years; interquartile range [IQR]: 50-67), had very little formal education (median: 3.7 years; IQR: 3.2-4.2), and had practiced traditional medicine for many years (median: 17 years; IQR: 9.5-30). Healers reported having the ability to successfully treat: seizure disorders (47%), patients who have lost touch with reality (47%), paralysis on one side of the body (59%), and substance abuse (21%). Female healers reported a lower odds of treating seizure disorders (Odds Ratio (OR):0.47), patients who had lost touch with reality (OR:0.26; p-value<0.05), paralysis of one side of the body (OR:0.36), and substance abuse (OR:0.36) versus males. Each additional year of education received was found to be associated with lower odds, ranging from 0.13-0.27, of treating these symptoms. Each additional patient seen by healers in the past week was associated with roughly 1.10 higher odds of treating seizure disorders, patients who have lost touch with reality, paralysis of one side of the body, and substance abuse. Healers charged a median of 500 South African Rand (~US$35) to treat substance abuse, 1000 Rand (~US$70) for seizure disorders or paralysis of one side of the body, and 1500 Rand (~US$105) for patients who have lost touch with reality.

CONCLUSIONS

While not all healers elect to treat MNS disorders, many continue to do so, delaying allopathic health services to acutely ill patients.

Traditional healer treatment of HIV persists in the era of ART: a mixed methods study from rural South Africa

BACKGROUND

Human immunodeficiency virus (HIV) substantially contributes to the burden of disease and health care provision in sub-Saharan Africa, where traditional healers play a major role in care, due to both their accessibility and acceptability. In rural, northeastern South Africa, people living with HIV often ping-pong between traditional healers and allopathic providers.

METHODS

We conducted 27 in-depth interviews and 133 surveys with a random sample of traditional healers living in Bushbuckridge, South Africa, where anti-retroviral therapy (ART) is publicly available, to learn: (1) healer perspectives about which HIV patients they choose to treat; (2) the type of treatment offered; (3) outcomes expected, and; (4) the cost of delivering treatment.

RESULTS

Healers were mostly female (77%), older (median: 58.0 years; interquartile range [IQR]: 50-67), with low levels of formal education (median: 3.7 years; IQR: 3.2-4.2). Thirty-nine healers (30%) reported being able to cure HIV in an adult patients whose (CD4) count was >350cells/mm³. If an HIV-infected patient preferred traditional treatment, healers differentiated two categories of known HIV-infected patients, CD4+ cell counts <350 or ≥350 cells/mm³. Patients with low CD4 counts were routinely referred back to the health facility. Healers who reported offering/performing a traditional cure for HIV had practiced for less time (mean = 16.9 vs. 22.8 years; p = 0.03), treated more patients (mean 8.7 vs. 4.8 per month; p = 0.03), and had lower levels of education (mean = 2.8 vs. 4.1 years; p = 0.017) when compared to healers who reported not treating HIV-infected patients. Healers charged a median of 92 USD to treat patients with HIV.

CONCLUSION

Traditional healers referred suspected HIV-infected patients to standard allopathic care, yet continued to treat HIV-infected patients with higher CD4 counts. A greater emphasis on patient education and healer engagement is warranted.

Adapting an adherence support workers intervention: engaging traditional healers as adherence partners for persons enrolled in HIV care and treatment in rural Mozambique

BACKGROUND

Systematic adaptation of evidence-informed interventions that increase retention in care and improve adherence to antiretroviral therapy (ART) are essential to ending the HIV epidemic in rural sub-Saharan Africa. We selected and adapted an adherence support worker intervention employed in Malawi for use by traditional healers in rural Mozambique. Given the levels of trust and dependence previously expressed by persons living with HIV (PLHIV) for traditional medicine, we adapted the program to engage traditional healers within the allopathic health system.

METHODS

Adaption followed a theoretically driven approach to intervention adaption: the Assessment-Decision-Administration-Production-Topical Experts-Integration-Training-Testing (ADAPT-ITT) model. Three rounds of performance feedback, based on theater presentations of the adapted intervention for stakeholders and idea generation, were completed with 12 groups from March to July 2016 to develop the final model. We offered healer support to 180 newly diagnosed HIV-infected patients.

RESULTS

Traditional healers were an acceptable group of community health workers to assist with patient adherence and retention. Traditional healers, clinicians, and interested community members suggested novel strategies to tailor the adherence support worker intervention, revealing a local culture of HIV denialism, aversion to the health system, and dislike of healthcare providers, as well as a preference for traditional treatments. Proposed changes to the intervention included modifications to the training language and topics, expanded community-based activities to support acceptability of an HIV diagnosis and to facilitate partner disclosure, and accompaniment to the health facility by healers to encourage delivery of respectful clinical care. PLHIV, healers, and clinicians deemed the intervention socially acceptable during focus groups. We subsequently recruited 180 newly diagnosed HIV-infected patients into the program: 170 (94%) accepted.

CONCLUSIONS

Systematic translation of interventions, even between regions with similar social and economic environments, is an important first step to successful program implementation. Efforts previously limited to community health workers can be tailored for use by traditional healers-an underutilized and often maligned health workforce. It proved feasible to use theater-based performances to demonstrate delivery of the intervention in low-literacy populations, generating discussions about social norms, community concerns, and the merits of an acceptable strategy to improve retention and adherence to ART.

Legal and regulatory framework for health worker retention in Mozambique: Public health law research to strengthen health systems and services

Realizing the fundamental contribution of human resources to public health, the World Health Organization (WHO) issued policy recommendations for health worker retention. We reviewed Mozambique's laws and regulations and assessed the extent to which this legal and regulatory framework governing public sector health workers aligns with the WHO health worker retention recommendations. We provide guidance for future analysis of non-binding policies that may fill gaps identified in our review. We also indicate how to link legal analysis to the cycle by which research informs policy, policy informs practice, and practice leads to improvements in health systems and population health. Finally, we demonstrate the relevance of understanding and analyzing the impact of domestic laws on global health. Future research should assess implementation of health worker allowances and any associations with increased hiring, more equitable distribution, and improved retention - all are essential to public health in Mozambique.Journal of Public Health Policy advance online publication, 26 May 2016; doi:10.1057/jphp.2016.22.

Closing the mental health gap in low-income settings by building research capacity: perspectives from Mozambique

BACKGROUND

Neuropsychiatric disorders are the leading cause of disability worldwide, accounting for 22.7% of all years lived with disability. Despite this global burden, fewer than 25% of affected individuals ever access mental health treatment; in low-income settings, access is much lower, although nonallopathic interventions through traditional healers are common in many venues. Three main barriers to reducing the gap between individuals who need mental health treatment and those who have access to it include stigma and lack of awareness, limited material and human resources, and insufficient research capacity. We argue that investment in dissemination and implementation research is critical to face these barriers. Dissemination and implementation research can improve mental health care in low-income settings by facilitating the adaptation of effective treatment interventions to new settings, particularly when adapting specialist-led interventions developed in high-resource countries to settings with few, if any, mental health professionals. Emerging evidence from other low-income settings suggests that lay providers can be trained to detect mental disorders and deliver basic psychotherapeutic and psychopharmacological interventions when supervised by an expert.

OBJECTIVES

We describe a new North-South and South-South research partnership between Universidade Eduardo Mondlane (Mozambique), Columbia University (United States), Vanderbilt University (United States), and Universidade Federal de São Paulo (Brazil), to build research capacity in Mozambique and other Portuguese-speaking African countries.

CONCLUSIONS

Mozambique has both the political commitment and available resources for mental health, but inadequate research capacity and workforce limits the country's ability to assess local needs, adapt and test interventions, and identify implementation strategies that can be used to effectively bring evidence-based mental health interventions to scale within the public sector. Global training and research partnerships are critical to building capacity, promoting bilateral learning between and among low- and high-income settings, ultimately reducing the mental health treatment gap worldwide.

The effects of utility evaluations, biomedical knowledge and modernization on intention to exclusively use biomedical health facilities among rural households in Mozambique

In resource-limited settings, the choice between utilizing biomedical health services and/or traditional healers is critical to the success of the public health mission. In the literature, this choice has been predicted to be influenced by three major factors: knowledge about biomedical etiologies; cultural modernization; and rational choice. The current study investigated all three of these predicted determinants, applying data from a general household survey conducted in 2010 in Zambézia Province of Mozambique involving 1045 randomly sampled rural households. Overall, more respondents (N = 802) intended to continue to supplement their biomedical healthcare with traditional healer services in comparison with those intending to utilize biomedical care exclusively (N = 243). The findings strongly supported the predicted association between rational utility (measured as satisfaction with the quality of service and results from past care) with the future intention to continue to supplement or utilize biomedical care exclusively. Odds of moving away from supplementation increase by a factor of 2.5 if the respondent reported seeing their condition improve under government/private biomedical care. Odds of staying with supplementation increase by a factor 3.1 if the respondent was satisfied with traditional care and a factor of 16 if the condition had improved under traditional care. Modernization variables (education, income, religion, and Portuguese language skills) were relevant and provided a significant component of the best scientific model. Amount of biomedical knowledge was not a significant predictor of choice. There was a small effect on choice from knowing the limitations of biomedical care. The findings have implications for public healthcare promotion activities in areas where biomedical care is introduced as an alternative to traditional healing.

Engagement of Traditional Healers and Birth Attendants as a Controversial Proposal to Extend the HIV Health Workforce

"Medical pluralism" is the use of multiple health systems and is common among people living with HIV/AIDS in sub-Saharan Africa. Healers and traditional birth attendants (TBAs) often are a patient's first and/or preferred line of treatment; this often results in delayed, interrupted, or abandoned diagnosis and therapy. Literature from the study of medical pluralism suggests that HIV care and treatment programs are infrequently and inconsistently engaging healers around the world. Mistrust and misunderstanding among patients, clinical providers, and traditional practitioners make the development of effective partnerships difficult, particularly regarding early HIV diagnosis and antiretroviral therapy. We provide recommendations for the development of successful collaboration health workforce efforts based on both published articles and case studies from our work in rural Mozambique.

Sociocultural and structural factors contributing to delays in treatment for children with severe malaria: a qualitative study in southwestern Uganda

Malaria is a leading cause of pediatric mortality, and Uganda has among the highest incidences in the world. Increased morbidity and mortality are associated with delays to care. This qualitative study sought to characterize barriers to prompt allopathic care for children hospitalized with severe malaria in the endemic region of southwestern Uganda. Minimally structured, qualitative interviews were conducted with guardians of children admitted to a regional hospital with severe malaria. Using an inductive and content analytic approach, transcripts were analyzed to identify and define categories that explain delayed care. These categories represented two broad themes: sociocultural and structural factors. Sociocultural factors were 1) interviewee's distinctions of “traditional” versus “hospital” illnesses, which were mutually exclusive and 2) generational conflict, where deference to one's elders, who recommended traditional medicine, was expected. Structural factors were 1) inadequate distribution of health-care resources, 2) impoverishment limiting escalation of care, and 3) financial impact of illness on household economies. These factors perpetuate a cycle of illness, debt, and poverty consistent with a model of structural violence. Our findings inform a number of potential interventions that could alleviate the burden of this preventable, but often fatal, illness. Such interventions could be beneficial in similarly endemic, low-resource settings.

Assessing spatial patterns of HIV knowledge in rural Mozambique using geographic information systems

OBJECTIVES

To conduct a cross-sectional mapping analysis of HIV knowledge in Zambézia Province, Mozambique, and to examine spatial patterns of HIV knowledge and associated household characteristics.

METHODS

A population-based cluster survey was administered in 2010; data were analysed from 201 enumeration areas in three geographically diverse districts: Alto Molócuè, Morrumbala and Namacurra. We assessed HIV knowledge scores (0-9 points) using previously validated assessment tools. Using geographic information systems (GIS), we mapped hot spots of high and low HIV knowledge. Our multivariable linear regression model estimated HIV knowledge associations with distance to nearest clinic offering antiretroviral therapy, respondent age, education, household size, number of children under five, numeracy, literacy and district of residence.

RESULTS

We found little overall HIV knowledge in all three districts. People in Alto Molócuè knew comparatively most about HIV, with a median score of 3 (IQR 2-5) and 22 of 51 (43%) enumeration areas scoring ≥4 of 9 points. Namacurra district, closest to the capital city and expected to have the best HIV knowledge levels, had a median score of 1 (IQR 0-3) and only 3 of 57 (5%) enumeration areas scoring ≥4 points. More HIV knowledge was associated with more education, age, household size, numeracy and proximity to a health facility offering antiretroviral therapy.

CONCLUSIONS

HIV knowledge is critical for its prevention and treatment. By pinpointing areas of poor HIV knowledge, programme planners can prioritize educational resources and outreach initiatives within the context of antiretroviral therapy expansion.

Barriers to health care in rural Mozambique: a rapid ethnographic assessment of planned mobile health clinics for ART

BACKGROUND

In Mozambique, 1.6 million people are living with HIV, and over 60% of the population lives in rural areas lacking access to health services. Mobile health clinics, implemented in 2013 in 2 provinces, are beginning to offer antiretroviral therapy (ART) and basic primary care services. Prior to introduction of the mobile health clinics in the communities, we performed a rapid ethnographic assessment to understand barriers to accessing HIV care and treatment services and acceptability and potential use of the mobile health clinics as an alternative means of service delivery.

METHODS

We conducted assessments in Gaza province in January 2013 and in Zambezia Province in April-May 2013 in districts where mobile health clinic implementation was planned. Community leaders served as key informants, and chain-referral sampling was used to recruit participants. Interviews were conducted with community leaders, health care providers, traditional healers, national health system patients, and traditional healer patients. Interviewees were asked about barriers to health services and about mobile health clinic acceptance.

RESULTS

In-depth interviews were conducted with 117 participants (Gaza province, n = 57; Zambezia Province, n = 60). Barriers to accessing health services included transportation and distance-related issues (reliability, cost, and travel time). Participants reported concurrent use of traditional and national health systems. The decision to use a particular health system depended on illness type, service distance, and lack of confidence in the national health system. Overall, participants were receptive to using mobile health clinics for their health care and ability to increase access to ART. Hesitations concerning mobile health clinics included potentially long wait times due to high patient loads. Participants emphasized the importance of regular and published visit schedules and inclusion of community members in planning mobile health clinic services.

CONCLUSION

Mobile health clinics can address many barriers to uptake of HIV services, particularly related to transportation issues. Involvement of community leaders, providers, traditional healers, and patients, as well as regularly scheduled mobile clinic visits, are critical to successful service delivery implementation in rural areas.

Incomplete adherence among treatment-experienced adults on antiretroviral therapy in Tanzania, Uganda and Zambia

OBJECTIVES

To characterize antiretroviral therapy (ART) adherence across different programmes and examine the relationship between individual and programme characteristics and incomplete adherence among ART clients in sub-Saharan Africa.

DESIGN

A cross-sectional study.

METHODS

Systematically selected ART clients (≥18 years; on ART ≥6 months) attending 18 facilities in three countries (250 clients/facility) were interviewed. Client self-reports (3-day, 30-day, Case Index ≥48 consecutive hours of missed ART), healthcare provider estimates and the pharmacy medication possession ratio (MPR) were used to estimate ART adherence. Participants from two facilities per country underwent HIV RNA testing. Optimal adherence measures were selected on the basis of degree of association with concurrent HIV RNA dichotomized at less than or greater/equal to 1000 copies/ml. Multivariate regression analysis, adjusted for site-level clustering, assessed associations between incomplete adherence and individual and programme factors.

RESULTS

A total of 4489 participants were included, of whom 1498 underwent HIV RNA testing. Nonadherence ranged from 3.2% missing at least 48 consecutive hours to 40.1% having an MPR of less than 90%. The percentage with HIV RNA at least 1000 copies/ml ranged from 7.2 to 17.2% across study sites (mean = 9.9%). Having at least 48 consecutive hours of missed ART was the adherence measure most strongly related to virologic failure. Factors significantly related to incomplete adherence included visiting a traditional healer, screening positive for alcohol abuse, experiencing more HIV symptoms, having an ART regimen without nevirapine and greater levels of internalized stigma.

CONCLUSION

Results support more in-depth investigations of the role of traditional healers, and the development of interventions to address alcohol abuse and internalized stigma among treatment-experienced adult ART patients.

Poor clinical outcomes for HIV infected children on antiretroviral therapy in rural Mozambique: need for program quality improvement and community engagement

INTRODUCTION

Residents of Zambézia Province, Mozambique live from rural subsistence farming and fishing. The 2009 provincial HIV prevalence for adults 15-49 years was 12.6%, higher among women (15.3%) than men (8.9%). We reviewed clinical data to assess outcomes for HIV-infected children on combination antiretroviral therapy (cART) in a highly resource-limited setting.

METHODS

We studied rates of 2-year mortality and loss to follow-up (LTFU) for children <15 years of age initiating cART between June 2006-July 2011 in 10 rural districts. National guidelines define LTFU as >60 days following last-scheduled medication pickup. Kaplan-Meier estimates to compute mortality assumed non-informative censoring. Cumulative LTFU incidence calculations treated death as a competing risk.

RESULTS

Of 753 children, 29.0% (95% CI: 24.5, 33.2) were confirmed dead by 2 years and 39.0% (95% CI: 34.8, 42.9) were LTFU with unknown clinical outcomes. The cohort mortality rate was 8.4% (95% CI: 6.3, 10.4) after 90 days on cART and 19.2% (95% CI: 16.0, 22.3) after 365 days. Higher hemoglobin at cART initiation was associated with being alive and on cART at 2 years (alive: 9.3 g/dL vs. dead or LTFU: 8.3-8.4 g/dL, p<0.01). Cotrimoxazole use within 90 days of ART initiation was associated with improved 2-year outcomes Treatment was initiated late (WHO stage III/IV) among 48% of the children with WHO stage recorded in their records. Marked heterogeneity in outcomes by district was noted (p<0.001).

CONCLUSIONS

We found poor clinical and programmatic outcomes among children taking cART in rural Mozambique. Expanded testing, early infant diagnosis, counseling/support services, case finding, and outreach are insufficiently implemented. Our quality improvement efforts seek to better link pregnancy and HIV services, expand coverage and timeliness of infant diagnosis and treatment, and increase follow-up and adherence.

Antiretroviral therapy program expansion in Zambézia Province, Mozambique: geospatial mapping of community-based and health facility data for integrated health planning

OBJECTIVE

To generate maps reflecting the intersection of community-based Voluntary Counseling and Testing (VCT) delivery points with facility-based HIV program demographic information collected at the district level in three districts (Ile, Maganja da Costa and Chinde) of Zambézia Province, Mozambique; in order to guide planning decisions about antiretroviral therapy (ART) program expansion.

METHODS

Program information was harvested from two separate open source databases maintained for community-based VCT and facility-based HIV care and treatment monitoring from October 2011 to September 2012. Maps were created using ArcGIS 10.1. Travel distance by foot within a 10 km radius is generally considered a tolerable distance in Mozambique for purposes of adherence and retention planning.

RESULTS

Community-based VCT activities in each of three districts were clustered within geographic proximity to clinics providing ART, within communities with easier transportation access, and/or near the homes of VCT volunteers. Community HIV testing results yielded HIV seropositivity rates in some regions that were incongruent with the Ministry of Health's estimates for the entire district (2-13% vs. 2% in Ile, 2-54% vs. 11.5% in Maganja da Costa, and 23-43% vs. 14.4% in Chinde). All 3 districts revealed gaps in regional disbursement of community-based VCT activities as well as access to clinics offering ART.

CONCLUSIONS

Use of geospatial mapping in the context of program planning and monitoring allowed for characterizing the location and size of each district's HIV population. In extremely resource limited and logistically challenging settings, maps are valuable tools for informing evidence-based decisions in planning program expansion, including ART.

Symptomatic HIV-positive persons in rural Mozambique who first consult a traditional healer have delays in HIV testing: a cross-sectional study

OBJECTIVE

Delays in HIV diagnosis and initiation of antiretroviral therapy are common even among symptomatic individuals in Africa. We hypothesized that antiretroviral therapy delays might be more common if traditional healers (THs) were the first practitioners consulted.

DESIGN

Cross-sectional study.

METHODS

We interviewed 530 newly diagnosed HIV-infected adults (≥18 years of age) who were clinically symptomatic at the time of HIV testing in 2 rural districts in Zambézia Province, Mozambique. We ascertained their previous health care seeking behavior, duration of their symptoms, CD4 cell counts at the time of entry into care, and treatment provided by TH(s).

RESULTS

Of 517 patients (97.5%) with complete histories, 62% sought care from a healer before presenting to the local health facility. The median time to first health facility visit from first relevant symptom was 2 months [interquartile range (IQR): 1-4.5] for persons who had not visited a healer, 3 months (IQR: 2-6) for persons visiting 1 healer, and 9 months (IQR: 5-12) for persons visiting >1 healer (P < 0.001). Healers diagnosed 56% of patients with a social or ancestral curse and treated 66% with subcutaneous herbal remedies. A nonsignificant trend toward lower CD4 cells for persons who had seen multiple healers was noted.

CONCLUSIONS

Seeking initial care from healers was associated with delays in HIV testing among symptomatic HIV-seropositive persons. We had no CD4 evidence that sicker patients bypass THs, a potential inferential bias. Engaging THs in a therapeutic alliance may facilitate the earlier diagnosis of HIV/AIDS.

Using verbal and social autopsies to explore health-seeking behaviour among HIV-positive women in Kenya: a retrospective study

BACKGROUND

There is limited understanding of the factors that influence decisions to seek HIV care and treatment services in community settings. The aim of this study was to explore the socio-cultural and health system factors affecting health-seeking behaviour among deceased women in Kenya who were living with HIV at the time of death.

METHODS

Out of a total of 796 deaths for which a caregiver was available to provide information, retrospective data were drawn from verbal and social autopsies administered to caregivers of 218 women who had died of AIDS-related illnesses aged 15 to 49 years. Information was collected on essential elements of the care-seeking process from the onset of severe illness episodes and analysed using qualitative and quantitative techniques.

RESULTS

Results from the quantitative data showed that poor women were less likely to access formal health services (OR = 0.2; p < 0.001) compared to non-poor women. The qualitative data showed that socioeconomic status, poor knowledge and understanding of AIDS-related illness, distance to facility and transportation costs, medical pluralism, stigma, low HIV risk perception, lack of family support and health care system barriers contributed to delays/constraints in seeking care.

CONCLUSIONS

The findings highlight important issues that have implications for addressing challenges faced by women living with HIV, including non-adherence to treatment regimen and late diagnosis of HIV. Provision of transportation subsidies as part of the national social safety-net strategy can help in addressing financial constraints associated with transportation costs among poor women living with HIV.

Disparities in pediatric oncology patient education and linguistic resources: results of a national survey of pediatric oncologists

BACKGROUND

Extensive patient and family education is required at the time of a new diagnosis of pediatric cancer yet little data exist regarding the availability and linguistic competency of new cancer diagnosis education provided by pediatric oncology institutions.

PROCEDURE

Using the American Society of Pediatric Hematology/Oncology (ASPHO) membership list, a web-based survey was conducted among a cohort of pediatric oncologists to determine pediatric oncologists' assessment of institutional resources for new cancer diagnosis education and the availability of linguistically appropriate education.

RESULTS

Of 1,294 ASPHO members sent email survey invitations, 573 (44.3%) responded with 429 meeting eligibility criteria. Oncologists at academic institutions reported their institutions had more availability of resources for new diagnosis education compared with those from non-academic institutions (mean 78.6 vs. 74.3; 0 [not at all]-100 [well equipped]; P = 0.05). The mean score increased with volume of new cancer diagnoses/year: small (<75) = 73.4; medium (75-149) = 76.7; large (>150) = 84.5 (P < 0.001). Oncologists at large volume institutions reported more availability of an established patient education protocol (50.8% vs. 38.1%, P < 0.001) and increased use of dedicated non-physician staff (79.9% vs. 66.1%, P = 0.02), but less use of websites for patient education (17.2% vs. 33.3%, P = 0.001). Availability of linguistically appropriate education improved with increasing institution size: small (76.4), medium (82.3), and large (84.0) patient volume (P < 0.011).

CONCLUSION

According to pediatric oncologists, a disparity in educational and linguistic resources for new pediatric cancer diagnosis education exists depending on institution type and size.

Educational intervention increased referrals to allopathic care by traditional healers in three high HIV-prevalence rural districts in Mozambique

INTRODUCTION

Delayed uptake of clinical services impedes favorable clinical outcomes in Mozambique. Care is delayed among patients who initiate care with traditional healers; patients with conditions like human immunodeficiency virus (HIV) or tuberculosis are rarely referred to the health system in a timely fashion.

METHODS

We conducted a pre-post educational intervention with traditional healers, assessing healer referral rates and HIV knowledge in three rural districts in Zambézia Province.

RESULTS

The median monthly referral rate prior to the intervention was 0.25 patients (interquartile range [IQR]: 0-0.54) compared with a post-intervention rate of 0.34 patients (IQR: 0-0.71), a 35% increase (p=0.046). A median HIV knowledge score of 67% (IQR: 59-78) was noted 4-months pre-intervention and a median score of 81% (IQR: 74-89) was recorded 2½ months post-intervention (p<0.001). One hundred and eleven healers referred 127 adults, 36 pregnant women, and 188 children to health facilities. Referred patients were most likely to be diagnosed with bronchopneumonia (20% adults; 13% children) and/or malaria (15% adults; 37% children). Of 315 non-pregnant persons referred, 3.5% were tested for HIV and 2.5% were tested for tuberculosis.

DISCUSSION

We engaged traditional healers with some success; referral rates were low, but increased post-intervention. Once seen in the clinics, patients were rarely tested for HIV or tuberculosis, though symptoms suggested screening was indicated. We found increased referral rates through an inexpensive intervention with traditional healers, a viable, cost-effective method of directing patients to health facilities. However, quality improvement within the clinics is necessary before a substantial impact can be expected.

Comprehensive knowledge of HIV among women in rural Mozambique: development and validation of the HIV knowledge 27 scale

Background

The relationship between HIV knowledge and HIV-related behaviors in settings like Mozambique has been limited by a lack of rigorously validated measures.

Methods

A convenience sample of women seeking prenatal care at two clinics were administered an adapted, orally-administered, 27 item HIV-knowledge scale, the HK-27. Validation analyses were stratified by survey language (Portuguese and Echuabo). Kuder-Richardson (KR-20) coefficients estimated internal reliability. Construct validity was assessed with bivariate associations between HK-27 scores (% correct) and selected participant characteristics. The association between knowledge, self-reported HIV testing, and HIV infection were evaluated with multivariable logistic regression.

Results

Participants (N = 348) had a median age of 24; 188 spoke Portuguese, and 160 spoke Echuabo. Mean HK-27 scores were higher for Portuguese-speaking participants than Echuabo-speaking participants (68% correct vs. 42%, p<0.001). Internal reliability was strong (KR-20>0.8) for scales in both languages. Higher HK-27 scores were significantly (p≤0.05) correlated with more education, more media items in the home, a history of HIV testing, and participant work outside of the home for women of both languages. HK-27 scores were independently associated with completion of HIV testing in multivariable analysis (per 1% correct: aOR:1.02, 95%CI:0.01–0.03, p = 0.01), but not with HIV infection.

Conclusions

HK-27 is a reliable and valid measure of HIV knowledge among Portuguese and Echuabo-speaking Mozambican women. The HK-27 demonstrated significant knowledge deficits among women in the study, and higher scores were associated with higher HIV testing probability. Future studies should evaluate the role of the HK-27 in longitudinal studies and in other populations.
