Integrating cardiovascular diseases, hypertension, and diabetes with HIV services: a systematic review

ABSTRACT Non-communicable diseases (NCDs), including cardiovascular diseases (CVD), hypertension and diabetes together with HIV infection are among the major public health concerns worldwide. Health services for HIV and NCDs require health systems that provide for people’s chronic care needs, which present an opportunity to coordinate efforts and create synergies between programs to benefit people living with HIV and/or AIDS and NCDs. This review included studies that reported service integration for HIV and/or AIDS with coronary heart diseases, chronic CVD, cerebrovascular diseases (stroke), hypertension or diabetes. We searched multiple databases from inception until October 2015. Articles were screened independently by two reviewers and assessed for risk of bias. 11,057 records were identified with 7,616 after duplicate removal. After screening titles and abstracts, 14 papers addressing 17 distinct interventions met the inclusion criteria. We categorized integration models by diseases (HIV with diabetes, HIV with hypertension and diabetes, HIV with CVD and finally HIV with hypertension and CVD and diabetes). Models also looked at integration from micro (patient focused integration) to macro (system level integrations). Most reported integration of hypertension and diabetes with HIV and AIDS services and described multidisciplinary collaboration, shared protocols, and incorporating screening activities into community campaigns. Integration took place exclusively at the meso-level, with no micro- or macro-level integrations described. Most were descriptive studies, with one cohort study reporting evaluative outcomes. Several innovative initiatives were identified and studies showed that CVD and HIV service integration is feasible. Integration should build on existing protocols and use the community as a locus for advocacy and health services, while promoting multidisciplinary teams, including greater involvement of pharmacists. There is a need for robust and well-designed studies at all levels – particularly macro-level studies, research looking at long-term outcomes of integration, and research in a more diverse range of countries.

Interventions and approaches to integrating HIV and mental health services: a systematic review

Background: The frequency in which HIV and AIDS and mental health problems co‐exist, and the complex bi‐directional relationship between them, highlights the need for effective care models combining services for HIV and mental health. Here, we present a systematic review that synthesizes the literature on interventions and approaches integrating these services. Methods: This review was part of a larger systematic review on integration of services for HIV and non‐communicable diseases. Eligible studies included those that described or evaluated an intervention or approach aimed at integrating HIV and mental health care. We searched multiple databases from inception until October 2015, independently screened articles identified for inclusion, conducted data extraction, and assessed evaluative papers for risk of bias. Results: Forty‐five articles were eligible for this review. We identified three models of integration at the meso and micro levels: single‐facility integration, multi‐facility integration, and integrated care coordinated by a non‐physician case manager. Single‐site integration enhances multidisciplinary coordination and reduces access barriers for patients. However, the practicality and cost‐effectiveness of providing a full continuum of specialized care on‐site for patients with complex needs is arguable. Integration based on a collaborative network of specialized agencies may serve those with multiple co‐morbidities but fragmented and poorly coordinated care can pose barriers. Integrated care coordinated by a single case manager can enable continuity of care for patients but requires appropriate training and support for case managers. Involving patients as key actors in facilitating integration within their own treatment plan is a promising approach. Conclusion: This review identified much diversity in integration models combining HIV and mental health services, which are shown to have potential in yielding positive patient and service delivery outcomes when implemented within appropriate contexts. Our review revealed a lack of research in low‐ and middle‐ income countries, and was limited to most studies being descriptive. Overall, studies that seek to evaluate and compare integration models in terms of long‐term outcomes and cost‐effectiveness are needed, particularly at the health system level and in regions with high HIV and AIDS burden.

Integrating cervical cancer with HIV healthcare services: a systematic review

Background Cervical cancer is a major public health problem. Even though readily preventable, it is the fourth leading cause of death in women globally. Women living with HIV are at increased risk of invasive cervical cancer, highlighting the need for access to screening and treatment for this population. Integration of services has been proposed as an effective way of improving access to cervical cancer screening especially in areas of high HIV prevalence as well as lower resourced settings. This paper presents the results of a systematic review of programs integrating cervical cancer and HIV services globally, including feasibility, acceptability, clinical outcomes and facilitators for service delivery. Methods This is part of a larger systematic review on integration of services for HIV and non-communicable diseases. To be considered for inclusion studies had to report on programs to integrate cervical cancer and HIV services at the level of service delivery. We searched multiple databases including Global Health, Medline and Embase from inception until December 2015. Articles were screened independently by two reviewers for inclusion and data were extracted and assessed for risk of bias. Main results 11,057 records were identified initially. 7,616 articles were screened by title and abstract for inclusion. A total of 21 papers reporting interventions integrating cervical cancer care and HIV services met the criteria for inclusion. All but one study described integration of cervical cancer screening services into existing HIV services. Most programs also offered treatment of minor lesions, a ‘screen-and-treat’ approach, with some also offering treatment of larger lesions within the same visit. Three distinct models of integration were identified. One model described integration within the same clinic through training of existing staff. Another model described integration through co-location of services, with the third model describing programs of integration through complex coordination across the care pathway. The studies suggested that integration of cervical cancer services with HIV services using all models was feasible and acceptable to patients. However, several barriers were reported, including high loss to follow up for further treatment, limited human-resources, and logistical and chain management support. Using visual screening methods can facilitate screening and treatment of minor to larger lesions in a single ‘screen-and-treat’ visit. Complex integration in a single-visit was shown to reduce loss to follow up. The use of existing health infrastructure and funding together with comprehensive staff training and supervision, community engagement and digital technology were some of the many other facilitators for integration reported across models. Conclusions This review shows that integration of cervical cancer screening and treatment with HIV services using different models of service delivery is feasible as well as acceptable to women living with HIV. However, the descriptive nature of most papers and lack of data on the effect on long-term outcomes for HIV or cervical cancer limits the inference on the effectiveness of the integrated programs. There is a need for strengthening of health systems across the care continuum and for high quality studies evaluating the effect of integration on HIV as well as on cervical cancer outcomes.

Self-Care for Older People (SCOPE): A cluster randomized controlled trial of self-care training and health outcomes in low-income elderly in Singapore

UNLABELLED Population aging is associated with a higher prevalence of chronic health conditions. Previous studies have shown that older persons, specifically those with chronic conditions, often lack sufficient knowledge about their condition and thus frequently have poor self-care skills. Efforts to increase general health screenings and improve access to chronic condition management resources are hampered by a lack of disease and health awareness. Self-Care for Older People (SCOPE) study, a cluster randomized controlled trial in Singapore, was designed to evaluate the impact of a self-care program for chronic disease awareness and management of specific health measures and quality of life of older people over eighteen months. SCOPE provided self-care education targeted at older people with low income and low education in order to improve health-related knowledge. A total of 378 low-income older people with no or minimal disability, defined as having difficulty in one or more activities of daily living (ADL), were recruited from senior activity centers. The measurements taken included self-reported health conditions, health and disease knowledge questions, and biomarkers (HbA1c, blood pressure, peak expiratory flow, lipid panel, albumin, and creatinine). SCOPE was also designed to provide information for policy makers on chronic disease burden and healthcare facility utilization among community-dwelling older adults. TRIAL REGISTRATION NUMBER NCT01672177.

Integrating HIV and substance use services: a systematic review

Introduction: Substance use is an important risk factor for HIV, with both concentrated in certain vulnerable and marginalized populations. Although their management differs, there may be opportunities to integrate services for substance use and HIV. In this paper we systematically review evidence from studies that sought to integrate care for people living with HIV and substance use problems.

Community participation in general health initiatives in high and upper-middle income countries: A systematic review exploring the nature of participation, use of theories, contextual drivers and power relations in community participation

Community participation is commonly regarded as pivotal in enabling the success of many health initiatives. However, the theoretical constructs, and evidence about the contextual drivers and relational issues that shape participation is lacking. The aim of this systematic review was to examine the evidence for published academic literature on community participation in relation to general, non-disease specific health initiatives, including the use of theories to inform community participation, and the study of contextual drivers and relational issues that influence community participation, with a focus on high and upper-middle income countries. We searched multiple databases including Medline, Embase, Scopus, LILACs and Global Health from January 2000 to September 2016. We screened papers for inclusion, then conducted data extraction and a narrative synthesis of the data. Only papers that focused on general health were included. Disease-specific literature was excluded. 27,232 records were identified, with 23,468 after duplicate removal. 79 papers met our final inclusion criteria. Overall, our findings show that strategies to encourage community participation in health initiatives can be categorized along a continuum that varies from less to more participation and control among the community. Our analysis of reported outcomes demonstrates that community participation in general health initiatives can contribute to positive process, social and health outcomes. Social outcomes are more often associated with increasing community participation in our selection of papers. Overall, our findings reaffirm the understanding that community participation is a complex process that is strongly influenced by the context in which it occurs, and that social factors such as power relations must be carefully considered. There is a need for more robustly designed studies to improve the theorization of community participation, and to draw out a better understanding of how tangible and intangible elements such as power, influence community participation and its outcomes.

Patient pathways and perceptions of hypertension treatment, management, and control in rural Bangladesh: a qualitative study

Purpose Hypertension is an increasing threat to global public health, a leading cause of premature death, and an important modifiable risk factor for cardiovascular and cerebrovascular disease. Despite evidence on the efficacy of antihypertensive medication for blood-pressure control and mortality prevention, a large proportion of individuals are undiagnosed and untreated, especially in resource-constrained settings. This qualitative study explored patient pathways to care, as well as knowledge of and adherence to hypertension care. Methods We conducted in-depth interviews with 20 hypertensive patients in two rural districts in Bangladesh. Interviews were conducted and transcribed in Bangla and translated to English. QSR NVivo 10 software was used for analyses. We mapped patient pathways and report here on patient experiences accessing care from local pharmacies, the government, and private clinics. Results Overall, most patients reported hypertension awareness prior to diagnosis and were conscious about consequences of hypertension. However, patients had little knowledge about prevention and treatment strategies. Most patients considered hypertension an important disease, albeit reporting taking medication only when symptomatic. Patients were aware of dietary advice; however, they were largely sedentary. Qualified doctors in both private and government settings diagnosed hypertension in the majority of the patients, and some were diagnosed by an informal provider and a few reported self-care at home. Patients followed three pathways: specialized hospitals for acute care, private hospitals/local pharmacy for nonacute symptoms, and incidental hypertension identification while being treated for another condition. Conclusion We identify barriers to access to hypertension prevention and care that prevented patients from seeking and receiving treatment from government facilities. Challenges included a lack of support to enable community screening by government health workers, long waiting times, and inadequate supplies for hypertension treatment. Expanding community-health workers’ scope in the dissemination of chronic-disease information may improve patient pathways to hypertension care in rural communities in Bangladesh.

Perspectives on acceptance and use of an mHealth intervention for the prevention of atherosclerotic cardiovascular disease in Singapore: A mixed methods study (Preprint)

Background Cardiovascular disease, including atherosclerotic cardiovascular disease (ASCVD), is a growing public health threat globally and many individuals remain undiagnosed, untreated, and uncontrolled. Simultaneously, mobile health (mHealth) interventions using short messaging service (SMS) have gained popularity globally. There is an opportunity for innovative approaches such as mHealth to encourage and enable adherence to medications for ASCVD and its risk factors. Objective This study aimed to understand mobile technology acceptance, use, and facilitating conditions among the study population ahead of the design of an mHealth intervention. Methods Using data from a mixed-methods study conducted in Singapore, we conducted a cross-sectional survey with 100 participants and in-depth, semistructured interviews with 20 patients. All participants were over the age of 40 years with ASCVD or its risk factors. Interviews were conducted in English and Mandarin and if needed translated to English. Nvivo 11 (QSR International) was used for analyses. Results Participants reported their perspectives on technology use and preferences, including low or sporadic mobile phone use and usability concerns including small screen and text size, among others; the benefit of previous mHealth use in creating a favorable opinion of SMS for health information; trust in both the source of mHealth SMS, as well as in treatment; the formation of habits; and fear of sequelae or death for facilitating intention to use an mHealth intervention and adhere to medication. We also highlighted a case that underscored the importance of the period after diagnosis in habit forming as an opportunity for an mHealth intervention. Conclusions We explored both technology- and adherence-related factors that influence a patient’s intention to use an mHealth intervention for adherence to ASCVD medication in Singapore. We highlighted the importance of identifying the right opportunity to engage with patients and promote an mHealth intervention for adherence, such as immediately following diagnosis when patients are establishing medication-taking habits.
