"It's because I think too much": Perspectives and experiences of adults with hypertension engaged in HIV care in northern Tanzania

Traditional and psychosocial factors associated with non-communicable diseases among people living with HIV in Cambodia: a cross-sectional study

We examined traditional and psychosocial factors associated with self-reported diabetes, hypertension, raised cholesterol, and multimorbidity among 4,089 people living with HIV in Cambodia. Participants were recruited from 20 antiretroviral therapy (ART) clinics across nine provinces and the capital city in 2021. Multiple logistic regression analyses assessed the associations between sociodemographic variables, HIV-related information, and psychosocial factors with the outcome variables. The prevalence of diabetes, hypertension, and raised cholesterol were 7.8%, 16.9%, and 6.6%, respectively. Non-adherence to ART (adjusted odds ratio [aOR]: 1.55, 95% confidence interval [CI]: 1.04-2.32), low self-efficacy in attending ART clinics regularly (aOR: 2.02, 95% CI: 1.16-3.53), and poor quality of life (aOR: 1.48, 95% CI: 1.13-1.94) were significantly associated with all outcomes. Interestingly, lower perceived social support was significantly associated with lower odds of hypertension (aOR: 0.52, 95% CI: 0.33-0.83) and multimorbidity (aOR: 0.40, 95% CI: 0.20-0.80). Past experiences with HIV-related stigma and discrimination were significantly associated with a higher likelihood of diabetes (aOR: 1.97, 95% CI: 1.23-3.15) and multimorbidity (aOR: 1.87, 95% CI: 1.23-2.85). Community-based interventions to enhance peer support and reduce stigma and discrimination may help decrease non-communicable diseases (NCDs), and integrating HIV and NCD programs could improve healthcare access among people living with HIV.

Community Health Worker Optimization of Antihypertensive Care in HIV (COACH): Study protocol for a pilot trial of an intervention to improve hypertension care among Tanzanians with HIV

OBJECTIVE

This study will evaluate the feasibility and preliminary effectiveness of the COACH (Community Health Worker Optimization of Antihypertensive Care in HIV) intervention, which integrates hypertension management into existing HIV care for people living with HIV (PLWH) in Tanzania.

METHODS

The study will be conducted at two HIV Care and Treatment Centers (CTCs) in Tanzania. In a single-arm pre-post feasibility trial, 100 PLWH with hypertension will be enrolled and will receive the six-month intervention. The COACH intervention includes six monthly hypertension educational sessions delivered by community health workers (CHWs) and integrated within HIV CTC visits, monthly blood pressure monitoring, follow up care coordination, fully subsidized antihypertensive medications, a standardized antihypertensive treatment algorithm, and training for providers. The intervention's implementation outcomes will be evaluated using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework, and the primary study outcome (reach of the intervention) will be the proportion of all scheduled intervention sessions attended by participants, a measure of feasibility. Secondary clinical effectiveness outcomes will include adherence to antihypertensive medication, blood pressure control, body mass index, cardiovascular risk, and hypertension knowledge.

SIGNIFICANCE

The COACH intervention has the potential to significantly improve hypertension management among PLWH in Tanzania by leveraging the existing HIV care infrastructure and CHWs. This study will provide crucial insights into the feasibility and potential effectiveness of the intervention in integrating hypertension care into HIV services, informing larger-scale implementation and policy changes in Tanzania and other resource-limitted settings.

Managing hypertension in rural Gambia and Kenya: Protocol for a qualitative study exploring the experiences of patients, health care workers, and decision-makers

Background

Hypertension is the single leading risk factor for premature death in Sub-Saharan Africa (SSA). Prevalence is high, but awareness, treatment, and control are low. Community-centred interventions show promise for effective hypertension management, but embedding such interventions sustainably requires a good understanding of the wider context within which they are being introduced. This study aims to conduct a systematic health system assessment exploring the micro (patients/carers), meso (health care workers and facilities), and macro (broader system) contexts in rural Gambia and Kenya.

Methods

This study will utilise various qualitative approaches. We will conduct (i) focus group discussions with people living with hypertensive to map a 'typical' patient journey through health systems, and (ii) in-depth interviews with patients and family carers, health care workers, decision-makers, and NCD partners to explore their experiences of managing hypertension and assess the capacity and readiness of the health systems to strengthen hypertension management. We will also review national guidelines and policy documents to map the organisation of services and guidance on hypertension management. We will use thematic analysis to analyse data, guided by the cumulative complexity model, and theories of organisational readiness and dissemination of innovations.

Expected findings

This study will describe the current context for the management of hypertension from the perspective of those involved in seeking (patients), delivering (health care workers) and overseeing (decision-makers) health services in rural Gambia and Kenya. It will juxtapose what should be happening according to health system guidance and what is happening in practice, drawing on the experiences of study participants. It will outline the various barriers to and facilitators of hypertension management, as perceived by patients, providers, and decision-makers, and the conditions that would need to be in place for effective and sustainable implementation of a community-centred intervention to improve the management of hypertension in rural settings.

Mapping evidence on barriers to and facilitators of diagnosing noncommunicable diseases among people living with human immunodeficiency virus in low- and middle-income countries in Africa: A scoping review

Objectives

To map the evidence on the barriers to and facilitators of diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries in Africa.

Introduction

Noncommunicable diseases are increasing among people living with HIV. Thus, strengthened and sustained diagnosis of noncommunicable diseases through integrated noncommunicable diseases and HIV care is needed to improve patient outcomes. However, there is paucity of evidence on the barriers and facilitators diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries.

Methods

The Arksey and O'Malley methodological framework was used. A comprehensive systematic search of academic databases (MEDLINE, Academic Search Complete, APA PsycInfo, CAB, and Health Source/Nursing) was performed via EBSCO search and PubMed. The articles were reviewed independently by three reviewers. The results were structured using Capability-Opportunity-Motivation-Behavior model and Theoretical Domains Framework.

Results

A total of 152 articles were retrieved for full-text review. Forty-one articles met the inclusion criteria. The identified barriers were relevant to all the Capability-Opportunity-Motivation-Behavior constructs and 14 Theoretical Domains Framework domains. A lack of knowledge and awareness of noncommunicable diseases, fear of stigma, financial problems and out-of-pocket payments were the most cited patient-level barriers. Healthcare providers (knowledge and awareness gaps, skill and competence deficiencies, unwillingness, burnout, low motivation, and apathy) were frequently cited. Lack of equipment, noncommunicable disease medications and supply chain challenges, lack of integrated noncommunicable disease and HIV care, and shortage of trained healthcare providers were identified as health-system-level barriers.

Conclusion

This scoping review is the first to identify barriers and facilitators using a theoretical framework. The most cited barriers include a lack of integrated HIV and noncommunicable disease care, equipment and logistics chain challenges for noncommunicable diseases, patients' and healthcare providers' lack of knowledge and awareness of noncommunicable diseases, and healthcare provider's skill and competency deficiencies. Addressing these issues is crucial for improving patient outcomes and reducing the burden on healthcare providers and health systems.

Determining the optimal diagnostic and risk stratification approaches for people with hypertension in two rural populations in Kenya and The Gambia: a study protocol for IHCoR-Africa Work Package 2

Background

Sub-Saharan Africa (SSA) has one of the highest prevalences of hypertension worldwide. The impact of hypertension is of particular concern in rural SSA, where access to clinics and hospitals is limited. Improvements in the management of people with hypertension in rural SSA could be achieved by sharing diagnosis and care tasks between the clinic and the community. To develop such a community-centred programme we need optimal approaches to identify and risk stratify patients with elevated blood pressure. The aim of the study is to improve the evidence base for diagnosis and risk estimation for a community-centred hypertension programme in two rural settings in SSA.

Methods

We will conduct a cross-sectional study of 1250 adult participants in Kilifi, Kenya and Kiang West, The Gambia. The study has five objectives which will determine the: (1) accuracy of three blood pressure (BP) measurement methods performed by community health workers in identifying people with hypertension in rural SSA, compared to the reference standard method; (2) relationship between systolic BP and cardiovascular risk factors; (3) prevalence of hypertension-mediated organ damage (HMOD); (4) accuracy of innovative point-of-care (POC) technologies to identify patients with HMOD; and (5) cost-effectiveness of different combinations of BP and HMOD measurements for directing hypertension treatment initiation.

Expected findings

This study will determine the accuracy of three methods for community BP measurement and POC technologies for HMOD assessment. Using the optimal methods in this setting it will estimate the prevalence of hypertension and provide the best estimate to date of HMOD prevalence in SSA populations. The cost-effectiveness of decision-making approaches for initiating treatment of hypertension will be modelled. These results will inform the development of a community-centred programme to improve care for hypertensive patients living in rural SSA. Existing community engagement networks will be used to disseminated within the research setting.

A Focused Group Perspective of Risk Factors for Hypertension Among Middle-Aged Adults in Rural Areas of Anambra State, Nigeria

PURPOSE

Recent records by the World Health Organization show that hypertension is more prevalent in Africa than in other parts of the world, and remains the foremost common risk factor for cardiovascular-related diseases, stroke, renal diseases, and death. However, little is known about the risk factors for hypertension by people from rural areas, especially among middle-aged adults. Therefore, the study examined the knowledge of the risk factors for hypertension among middle-aged adults in rural areas of Anambra state, Nigeria.

MATERIALS, AND METHOD

Focus group discussions were used to collect data from 40 middle-aged adults (20 males and 20 females). Two key themes stood out from the data collection guides. These are "awareness of hypertension and its' symptoms" and "knowledge of risk factors of hypertension".

RESULTS

The findings showed that the participants were aware of hypertension but lacked in-depth knowledge of the risk factors for the disease. Most participants did not believe that intake of certain foods like starchy foods and excess alcohol consumption could lead to one being hypertensive.

DISCUSSION AND CONCLUSION

There is a need for social workers to sensitize and enlighten the middle-aged adults in the study area on the risk factors for the disease.

Patient and provider perspectives on barriers to myocardial infarction care among persons with human immunodeficiency virus in Tanzania: A qualitative study

INTRODUCTION

People with HIV (PLWH) have an increased risk myocardial infarction (MI), and evidence suggests that MI is under-diagnosed in Tanzania. However, little is known about barriers to MI care among PLWH in the region.

METHODS

In this qualitative study grounded in phenomenology, semi-structured interviews were conducted in northern Tanzania. Purposive sampling was used to recruit a diverse group of providers who care for PLWH and patients with HIV and electrocardiographic evidence of prior MI. Emergent themes were identified via inductive thematic analysis.

RESULTS

24 physician and patient participants were interviewed. Most participants explained MI as caused by emotional shock and were unaware of the association between HIV and increased MI risk. Providers described poor provider training regarding MI, high out-of-pocket costs, and lack of diagnostic equipment and medications. Patients reported little engagement with and limited knowledge of cardiovascular care, despite high engagement with HIV care. Most provider and patient participants indicated that they would prefer to integrate cardiovascular care with routine HIV care.

CONCLUSIONS

PLWH face many barriers to MI care in Tanzania. There is a need for multifaceted interventions to educate providers and patients, improve access to MI diagnosis, and increase engagement with cardiovascular care among this population.

"High blood pressure comes from thinking too much": Understandings of illness among couples living with cardiometabolic disorders and HIV in Malawi

Cardiometabolic disorders (CMD) such as hypertension and diabetes are increasingly prevalent in sub-Saharan Africa, placing people living with HIV at risk for cardiovascular disease and threatening the success of HIV care. Spouses are often the primary caregivers for people living with CMD, and understanding patients' and partners' conceptions of CMD could inform care. We conducted semi-structured interviews with 25 couples having a partner living with HIV and either hypertension or diabetes. Couples were recruited from HIV clinics in Malawi and were interviewed on beliefs around symptoms, causation, prevention, and treatment for CMD. Data were analyzed at the individual and dyadic levels using framework analysis and Kleinman's theory of explanatory models as a lens. On average, participants were 51 years old and married for 21 years. Approximately 57%, 14%, and 80% had hypertension, diabetes, and HIV. Couples endorsed a combination of biomedical explanatory models (beliefs around physical and mental health) and traditional explanatory models (beliefs around religion and natural remedies), although tended to emphasize the biomedical model. Half of couples believed stress was the main cause of hypertension. For diabetes, diet was believed to be a common cause. In terms of prevention, dietary changes and physical activity were most frequently mentioned. For disease management, medication adherence and diet modifications were emphasized, with some couples also supporting herbal remedies, stress reduction, and faith in God as strategies. Participants were generally more concerned about CMD than HIV due to poor access to CMD medications and beliefs that CMD could lead to sudden death. Within couples, partners often held many of the same beliefs but diverged around which etiological or preventive factors were most important (e.g., stress versus diet) and the best diet for CMD. Health education programs should involve primary partners to build knowledge of CMD and address overlap with HIV, and reinforce accurate information on lifestyle factors for the prevention and treatment of CMD.

Six month incidence of major adverse cardiovascular events among adults with HIV in northern Tanzania: a prospective observational study

OBJECTIVES

We aimed to prospectively describe incident cardiovascular events among people living with HIV (PLWH) in northern Tanzania. Secondary aims of this study were to understand non-communicable disease care-seeking behaviour and patient preferences for cardiovascular care and education.

DESIGN

A prospective observational study.

SETTING

This study was conducted at the Majengo HIV Care and Treatment Clinic, an outpatient government-funded clinic in Moshi, Tanzania PARTICIPANTS: Adult patients presenting to an HIV clinic for routine care in northern Tanzania were enrolled from 1 September 2020 to 1 March 2021.

INTERVENTIONS

At enrolment, participants completed a survey and a resting 12-lead ECG was obtained. At 6 month follow-up, a repeat survey regarding interim health events and repeat ECG was obtained.

PRIMARY AND SECONDARY OUTCOME MEASURES

Interim major adverse cardiovascular events (MACE) were defined by: self-reported interim stroke, self-reported hospitalisation for heart failure, self-reported interim myocardial infarction, interim myocardial infarction by ECG criteria (new pathologic Q waves in two contiguous leads) or death due to cardiovascular disease (CVD).

RESULTS

Of 500 enrolled participants, 477 (95.4%) completed 6 month follow-up and 3 (0.6%) died. Over the 6 month follow-up period, 11 MACE occurred (3 strokes, 6 myocardial infarctions, 1 heart failure hospitalisation and 1 cardiovascular death), resulting in an incidence rate of 4.58 MACE per 100 person-years. Of participants completing 6 month follow-up, 31 (6.5%) reported a new non-communicable disease diagnosis, including 23 (4.8%) with a new hypertension diagnosis.

CONCLUSIONS

The incidence of MACE among PLWH in Tanzania is high. These findings are an important preliminary step in understanding the landscape of CVD among PLWH in Tanzania and highlight the need for interventions to reduce cardiovascular risk in this population.

'My people perish for lack of knowledge': barriers and facilitators to integrated HIV and hypertension screening at the Kenyatta National Hospital, Nairobi, Kenya

INTRODUCTION

HIV and cardiovascular disease (CVD) are the two main causes of death in Kenya with hypertension as CVD's leading risk factor and HIV infection a risk factor for hypertension. We qualitatively evaluated the feasibility of integrated HIV and hypertension screening at Kenyatta National Hospital.

METHODS

We conducted two focus group discussions (FGDs) in November 2020 (female FGD: n=7; male FGD: n=8) to elicit facilitators, barriers and viability of integrated diagnosis and management of both conditions at HIV testing service (HTS) facilities. Participants were selected using convenience sampling and were not pair matched. All participants had received HTS. All female clients had confirmed hypertension, while male relatives had been contacted for HIV and hypertension screening through a modified assisted partner services model-where a trained healthcare provider supports notification. Transcripts were coded independently, and the codebook was developed and revised through consensus discussion. Data were analysed using thematic content analysis.

RESULTS

Main barriers to diagnosis and management included limited public awareness of hypertension risk factors and on improved treatment outcomes for those on lifelong HIV treatment, high cost of hypertension care despite free HIV care and healthcare system challenges especially medication stockouts. Strong support systems at family and healthcare levels facilitated care and treatment for both conditions. Participants recommended improved public awareness through individual-level communication and mass media campaigns, decentralised screening services for both HIV and hypertension, and either free or subsidised hypertension care services delivered alongside HIV treatment services. Most felt that an integrated HIV and hypertension service model was viable and would improve healthcare outcomes.

CONCLUSION

Patient-centred care models combining HIV and hypertension services hold promise for integrated service delivery.

Six-month blood pressure and glucose control among HIV-infected adults with elevated blood pressure and hyperglycemia in northern Tanzania: A prospective observational study

BACKGROUND

People with HIV in sub-Saharan Africa are increasingly developing age-related comorbidities. The purpose of this prospective observational study was to describe 6-month outcomes among Tanzanians with HIV and elevated blood pressure or hyperglycemia under current care pathways.

METHODS

Adults presenting for routine HIV care were enrolled and underwent blood pressure and blood glucose measurements. Participants with abnormal blood pressure or glucose were referred for further care, as per current guidelines. Participants' blood pressure and point-of-care glucose were re-evaluated during their 6-month follow-up visit. Elevated blood pressure was defined as systolic ≥140 mmHg or diastolic ≥90 mmHg. Hyperglycemia was defined as fasting glucose ≥126 mg/dl or random glucose ≥200 mg/dl. An electrocardiogram was obtained at enrollment and at follow-up. Interim myocardial infarction and interim myocardial ischemia were defined as new pathologic Q waves and new T-wave inversions, respectively.

RESULTS

Of 500 participants, 155 had elevated blood pressure and 17 had hyperglycemia at enrolment. At 6-month follow-up, 7 (4.6%) of 155 participants with elevated blood pressure reported current use of an anti-hypertensive medication, 100 (66.2%) had persistent elevated blood pressure, 12 (7.9%) developed interim myocardial infarction, and 13 (8.6%) developed interim myocardial ischemia. Among 17 participants with hyperglycemia, 9 (56%) had persistent hyperglycemia at 6 months and 2 (12.5%) reported current use of an anti-hyperglycemic medication.

CONCLUSIONS

Interventions are needed to improve non-communicable disease care pathways among Tanzanians with HIV.

Hypertension in an Emergency Department Population in Moshi, Tanzania; A Qualitative Study of Barriers to Hypertension Control

BACKGROUND

Sub-Saharan Africa has a high prevalence of hypertension with a low rate of awareness, treatment adherence, and control. The emergency department (ED) may represent a unique opportunity to improve hypertension screening, awareness, and linkage to care. We conducted a qualitative study among hypertensive patients presenting to the ED and their healthcare providers to determine barriers to hypertension care and control.

METHODS

In northern Tanzania, between November and December 2017, we conducted three focus group discussions among patients with hypertension presenting to the emergency department and three in-depth interviews among emergency department physicians. In our study, hypertension was defined as a single blood pressure of ≥160/100 mm Hg or a two-time average of ≥140/90 mm Hg. Barriers to care were identified by thematic analysis applying an inductive approach within the framework method.

RESULTS

We enrolled 24 total patients into three focus groups and performed three in-depth interviews with individual providers. Thematic analysis identified two major domains: 1) patient knowledge, attitudes, and practices, and 2) structural barriers to hypertension care. Four major themes emerged within the knowledge, attitudes, and practices domain, including disease chronicity, provider communication, family support, and fear-based attitudes. Within the structural domain, several themes emerged that identified barriers that impeded hypertension follow-up care and self-management, including cost, access to care, and transportation and wait time.

CONCLUSION

Patients and physicians identified multiple barriers and facilitators to hypertension care. These perspectives may be helpful to design emergency department-based interventions that target blood pressure control and linkage to outpatient care.

Understanding barriers and facilitators to clinic attendance and medication adherence among adults with hypertensive urgency in Tanzania

Hypertensive urgency is a major risk factor for cardiovascular events and premature deaths. Lack of medication adherence is associated with poor health outcomes among patients with hypertensive urgency in resource-limited settings. To inform the development of tailored interventions to improve health outcomes in this population, this study aimed at understanding facilitators and barriers to clinic attendance and medication adherence among Tanzanian adults with hypertensive urgency. We conducted in-depth interviews with 38 purposively selected participants from three groups: 1) patients with hypertension attending hypertension clinic, 2) patients with hypertension not attending hypertension clinic, and 3) clinic health workers. Interviews were conducted using a semi-structured guide which included open-ended questions with prompts to encourage detailed responses. In their narrative, patients and healthcare workers discussed 21 types of barriers/facilitators to clinic attendance and medication adherence: 12 common to both behaviors (traditional medicine, knowledge and awareness, stigma, social support, insurance, reminder cues, symptoms, self-efficacy, peer support, specialized care, social services, religious beliefs); 6 distinct to clinic attendance (transport, clinic location, appointment, patient-provider interaction, service fragmentation, quality of care); and 3 distinct to medication adherence (drug stock, side effects, medicine beliefs). The majority of identified barriers/facilitators overlap between clinic attendance and medication adherence. The identified barriers may be surmountable using tailored supportive intervention approaches, such as peer counselors, to help patients overcome social challenges of clinic attendance and medication adherence.

A community health worker delivered intervention to address hypertension among adults engaged in HIV care in northern Tanzania: Outcomes from a pilot feasibility study

Current care models are inadequate to address the dual epidemic of hypertension and HIV in sub‐Saharan Africa. We developed a community health worker (CHW)‐delivered educational intervention, integrated into existing HIV care to address hypertension in persons living with HIV. A detailed educational curriculum was created with five sessions: three in‐person clinic sessions and two telephone sessions. The intervention was piloted among hypertensive adults at one HIV clinic in northern Tanzania over a 4‐week period. Primary outcomes were feasibility, fidelity, and acceptability of the intervention. Secondary outcomes included hypertension care engagement and systolic and diastolic blood pressure (SBP and DBP). Among 16 eligible participants, 14 (64% women, median age of 54.5 years) were recruited into the study, and 13 (92.9%) completed all five intervention sessions. The intervention was delivered with 98.8% fidelity to the curriculum content. Hypertension care engagement improved following the intervention. At baseline, two (15.4%) participants had seen a doctor previously for hypertension, compared to 11 (84.6%) participants post‐intervention (P = .0027). No participant was using antihypertensives at baseline, compared to 10 (76.9%) post‐intervention (P = .0016). Pre‐intervention median SBP was 164 (IQR 152–170) mmHg, compared to post‐intervention SBP of 146 (IQR 134–154) mmHg (P = .0029). Pre‐intervention median DBP was 102 (IQR 86–109) mmHg, compared to post‐intervention DBP of 89 (IQR 86–98) mmHg (P = .0023). A CHW‐delivered educational intervention, integrated into existing HIV care, is feasible and holds promise in improving hypertension care engagement and reducing blood pressure. Further research is needed to evaluate the efficacy and scale‐up of our intervention.

Hypertension among adults enrolled in HIV care in northern Tanzania: comorbidities, cardiovascular risk, and knowledge, attitudes and practices

Introduction

the epidemiology of non-communicable diseases (NCDs) among people living with HIV (PLHIV) in sub-Saharan Africa is poorly described. In this observational study we examined a cohort of hypertensive PLHIV in northern Tanzania and described comorbidities, cardiovascular risk, and hypertension knowledge, attitudes and practices.

Methods

consecutive patients attending an HIV clinic were screened for hypertension; those who met hypertension study criteria were enrolled. Participants completed a hypertension knowledge, attitudes and practices survey, and underwent height, weight, and waist circumference measurements and urine dipstick, fasting blood sugar, and lipid panel analyses. Kidney disease was defined as 1+ proteinuria, diabetes mellitus was defined as fasting glucose >126mg/dL, and 10-year atherosclerotic cardiovascular disease (ASCVD) risk was defined per the Pooled Cohorts Equations.

Results

of 555 screened patients, 105 met hypertension criteria and 91 (86.7%) were enrolled. The prevalence of diabetes mellitus, kidney disease, and overweight or obesity was 8.8%, 28.6%, and 86.7%, respectively. Almost all participants (n=86, 94.5%) had two or more medical comorbidities. More than half (n=39, 52.7%) had intermediate or high 10-year risk for an ASCVD event. While only 3 (3.3%) participants were able to define hypertension correctly, most would seek care at a medical facility (n=89, 97.8%) and take medication chronically for hypertension (n=79, 87.8%).

Conclusion

we found a high burden of medical comorbidity and ASCVD risk among hypertensive PLHIV in northern Tanzania. Integration of routine NCD screening in the HIV clinical setting, in combination with large-scale educational campaigns, has the potential to impact clinical outcomes in this high-risk population.

"If They Give Their Mind to HIV, They Don't Last as Long": An Explanatory Model of HIV Infection in a Limited-Resource Setting Informs Person-Centered Care

Explanatory models describe individuals' perceptions of their illness experiences, which can guide culturally relevant care. We constructed an explanatory model of the experience of living with human immunodeficiency virus (HIV) in the Dominican Republic. Following qualitative descriptive methodology, we conducted interviews in Spanish using a semi-structured interview guide developed using Kleinman's explanatory model framework. Two bilingual researchers coded interview transcripts following conventional content analysis. We used deductive codes from Kleinman's framework and inductive codes external to the framework to construct the codebook. We arranged codes by shared meaning into categories and constructed themes that reflected shared findings from inductive categories and deductive codes. Twenty-six persons living with HIV participated. They provided rich descriptions of their experiences represented by four cross-cutting themes, which informed the explanatory model. By incorporating this in-depth understanding of patients' illness experiences into care delivery, nurses can cultivate culturally meaningful and trusting patient-centered partnerships that improve health.

Knowledge, attitudes, and preventive practices regarding ischemic heart disease among HIV-positive individuals in northern Tanzania

OBJECTIVES

To describe knowledge, attitudes, and practices (KAP) regarding ischemic heart disease (IHD) among adults with HIV in Tanzania.

METHODS

Adults presenting for routine HIV care at a clinic in northern Tanzania were consecutively enrolled and were administered a standardised KAP survey. For each participant, an IHD knowledge score was calculated by tallying correct answers to the IHD knowledge questions, with maximum score 10. Individual 5-year risk of cardiovascular event was calculated using the Harvard NHANES model. Associations between participant characteristics and IHD knowledge scores were assessed via Welch's t-test.

RESULTS

Among the 500 participants, the mean (SD) age was 45.3 (11.4) years and 139 (27.8%) were males. Most participants recognised high blood pressure (n = 313, 62.6%) as a risk factor for IHD, but fewer identified diabetes as a risk factor (n = 241, 48.2%), or knew that aspirin reduces the risk of a secondary cardiovascular event (n = 73, 14.6%). Higher IHD knowledge score was associated with post-primary education (mean 6.27 vs. 5.35, p = 0.001) and with >10% 5-year risk of cardiovascular event (mean 5.97 vs. 5.41, p = 0.045). Most participants believed there were things they could do to reduce their chances of having a heart attack (n = 361, 72.2%). While participants indicated that they adhered to their prescribed medications (n = 488, 97.6%), only 106 (21.2%) attended regular health check-ups.

CONCLUSION

Efforts are needed to improve gaps in IHD knowledge, and increase uptake of cardiovascular preventative practices among Tanzanian adults with HIV.

Patient perspectives on integrated healthcare for HIV, hypertension and type 2 diabetes: a scoping review

INTRODUCTION

Antiretroviral therapy has reduced mortality and led to longer life expectancy in people living with HIV. These patients are now at an increased risk of non-communicable diseases (NCDs). Integration of care for HIV and NCDs has become a focus of research and policy. In this article, we aim to review patient perspectives on integration of healthcare for HIV, type 2 diabetes and hypertension.

METHODS

The framework for scoping reviews developed by Arksey and O'Malley and updated by Peter et al was applied for this review. The databases PubMed, Web of Science and Cochrane library were searched. Broad search terms for HIV, NCDs (specifically type 2 diabetes and hypertension) and healthcare integration were used. As the review aimed to identify definitions of patient perspectives, they were not included as an independent term in the search strategy. References of included publications were searched for relevant articles. Titles and abstracts for these papers were screened by two independent reviewers. The full texts for all the publications appearing to meet the inclusion criteria were then read to make the final literature selection.

RESULTS

Of 5502 studies initially identified, 13 articles were included in this review, of which 11 had a geographical origin in sub-Saharan Africa. Nine articles were primarily focused on HIV/diabetes healthcare integration while four articles were focused on HIV/hypertension integration. Patient's experiences with integrated care were reduced HIV-related stigma, reduced travel and treatment costs and a more holistic person-centred care. Prominent concerns were long waiting times at clinics and a lack of continuity of care in some clinics due to a lack of healthcare workers. Non-integrated care was perceived as time-consuming and more expensive.

CONCLUSION

Patient perspectives and experiences on integrated care for HIV, diabetes and hypertension were mostly positive. Integrated services can save resources and allow for a more personalised approach to healthcare. There is a paucity of evidence and further longitudinal and interventional evidence from a more diverse range of healthcare systems are needed.

Hypertension Care for People With HIV in Tanzania: Provider Perspectives and Opportunities for Improvement

One in three people with HIV (PWH) has hypertension. However, most hypertensive PWH in sub-Saharan Africa are unaware of their hypertension diagnosis and are not on treatment. To better understand barriers to hypertension care faced by PWH, we interviewed 15 medical providers who care for patients with HIV and hypertension in northern Tanzania. The data revealed barriers at the patient, provider, and system level and included: stress, depression, and HIV-related stigma; lack of hypertension knowledge; insufficient hypertension training; inefficient prescribing practices; challenges with counselling; capacity limitations in hypertension care; high costs of care; and lack of routine hypertension screening and follow-up. Opportunities for improvement focused on prioritizing resources and funding towards hypertension care. System-related challenges were the underlying cause of barriers at individual levels. Strategies that focus on strengthening capacity and utilize existing HIV platforms to promote hypertension care delivery are urgently needed to improve cardiovascular outcomes among PWH.

Recognition and management of clinically significant drug-drug interactions between antiretrovirals and co-medications in a cohort of people living with HIV in rural Tanzania: a prospective questionnaire-based study

BACKGROUND

The extent to which drug-drug interactions (DDIs) between antiretrovirals (ARVs) and co-medications are recognized and managed has not been thoroughly evaluated in limited-resource settings.

OBJECTIVES

This prospective questionnaire-based study aimed to determine the prevalence and risk factors for unrecognized/incorrectly managed DDIs in people living with HIV followed-up at the Chronic Diseases Clinic of Ifakara (CDCI) and enrolled in the Kilombero and Ulanga Antiretroviral Cohort (KIULARCO).

METHODS

We prospectively included ARV-treated adults receiving ≥1 co-medication coming for a follow-up visit at the CDCI between March and July 2017. Using a structured questionnaire, physicians were requested to identify potentially clinically significant DDIs in the prescribed treatment, to provide recommendations for their management and to indicate any hurdles to implement the recommendations. Prescriptions were subsequently screened for DDIs using the Liverpool DDIs database. Identified clinically significant DDIs and their recommended management according to the DDIs database were compared with the information provided in the questionnaires.

RESULTS

Among 334 participants, the median age was 47 years (IQR = 40-56 years), 69% were female and 82% had ≥1 non-communicable disease (NCD). Overall, 129 participants had ≥1 clinically relevant DDI, which was not recognized and/or incorrectly managed in 56 participants (43%). Of those, 6 (11%) were due to limited monitoring options or medication affordability issues. In the multivariable logistic regression, the presence of ≥1 NCD was associated with an increased risk for unrecognized/incorrect DDI management (OR = 15.8; 95% CI = 1.8-139.6).

CONCLUSIONS

Recognition/appropriate management of DDIs is suboptimal, highlighting the need for educational programmes, pharmacovigilance activities and increased access to medications and monitoring options. This should become a focus of HIV programmes given the increasing burden of NCDs in sub-Saharan Africa.
