Empowerment interventions designed for persons living with chronic disease - a systematic review and meta-analysis of the components and efficacy of format on patient-reported outcomes

BACKGROUND

Empowerment approaches are essential for building the capacity of individuals with chronic disease to be in control of their health. Reviews of empowerment interventions have been focused on specific chronic diseases, thereby limiting the scope of findings. This study had three aims: 1) to describe the characteristics of empowerment interventions covering a broad range of chronic diseases, 2) to clarify consistency with the World Health Organization`s (WHO) definition of empowerment as a process composed of four fundamental components and 3) to summarize outcome measures and estimate the effects in group and individual intervention formats.

METHODS

Systematic literature review and meta-analysis. CINAHL, Medline, Embase, PsycINFO, Web of Science, COCHRANE and Central Register of Controlled Trials were searched using Chronic Disease, NCD, Empowerment, as MeSH terms. Eligible randomized and quasi randomized controlled trials were included. Review Manager 5.4 was used to conduct the meta-analysis. Risk of bias was assessed with the Cochrane risk-of-bias tool (ROB 2).

RESULTS

Thirty-nine articles representing 8,011 participants were included in the review. A majority (82%) of studies reported robust evidence for changes on study-defined outcome measures in favor of interventions. Intervention content was assessed against WHO's four fundamental components of empowerment, showing that all studies incorporated one component, but none targeted all components. Components reflecting knowledge acquisition, patient engagement with their health care providers and facilitating environment were scarcely reported. Meta-analyses found evidence for positive effects of group-format interventions measuring empowerment, HbA1c, and self-efficacy. Effects on empowerment were also found in some individual-format interventions. High levels of heterogeneity and variability among the conceptual frameworks were identified.

CONCLUSION

Empowerment interventions in group-format were most efficient, however, considerable conceptual inconsistencies were identified. Future studies should consolidate conceptual understandings by using WHO's empowerment framework to ensure that fundamental components of empowerment are explicitly included in intervention design. Furthermore, there is a need to clarify the role of empowerment through pathways that include patient activation, self- management, and clinical outcomes. This systematic review will inform the clinicians and researchers who aim to develop novel empowerment interventions to assist patients in the process of gaining control of their health.

Health Care Professionals' Experiences of Facilitating Patient Activation and Empowerment in Chronic Illness using a Person-Centered and Strengths-Based Self-Management Program

OBJECTIVE

Patients with chronic illness who are empowered and activated are more likely to engage in self-management in order to stabilise their condition and enhance their quality of life. This study aimed to explore Health Care Professional's (HCP) assessment of a person-centered intervention called 'The Bodyknowledging Program' (BKP) for the facilitation of empowerment and patient activation in the context of chronic illness.

METHODS

This study employed a qualitative process evaluation after programme completion. Data was collected through focus-groups and individual interviews with HCPs and content analysis was used in the analysis.

RESULTS

Four themes were identified: 1) Shifts towards the patient-perspective, 2) The value of a patient-centered conceptual framework, 3) Patient activation through dialogue based support and 4) Challenging competencies. Discussion: This study introduces 'The Bodyknowledging Program' as a useful tool to uncover patients' needs and to activate and empower them to take more responsibility for their health through self-care management. The usability of the new intervention depends on HCP's ability to develop their counselling skills and changing their approach towards utilising patients' individual resources in the promotion of their health.

"Live a normal life": Constructions of resilience among people in mixed HIV status relationships in Canada

Positive Plus One is a mixed-methods study of long-term mixed HIV-serostatus relationships in Canada (2016-19). Qualitative interviews with 51 participants (10 women, 41 men, including 27 HIV-positive and 24 HIV-negative partners) were analyzed using inductive thematic analysis to examine notions of relationship resilience in the context of emerging HIV social campaigns. Relationship resilience meant finding ways to build and enact life as a normal couple, that is, a couple not noticeably affected by HIV, linked to the partner with HIV maintaining viral suppression and achieving "undetectable = untransmittable" (U = U). Regardless of serostatus, participants with material resources, social networks, and specialized care were better able to construct resilience for HIV-related challenges within their relationships. Compared to heterosexual couples and those facing socioeconomic adversity, gay and bisexual couples were easier able to disclose, and access capital, networks and resources supporting resilience. We conclude that important pathways of constructing, shaping, and maintaining resilience were influenced by the timing of HIV diagnosis in the relationship, access to HIV-related information and services, disclosure, stigma and social acceptance.

Reducing HIV-related stigma among young people attending school in Northern Uganda: study protocol for a participatory arts-based population health intervention and stepped-wedge cluster-randomized trial

BACKGROUND

HIV-related stigma negatively impacts HIV prevention, treatment, and care, particularly among children and adolescents in sub-Saharan Africa. Interventions that are culturally grounded and relevant for addressing root causes may reduce the stigma experienced by HIV-positive and HIV-affected young people. This study, to be conducted in a post-conflict, rural setting in Omoro District, Uganda, will develop and evaluate a transformative  arts-based HIV-related stigma intervention rooted in local cultural knowledge to reduce stigma and improve HIV prevention and care for young people living with HIV. The intervention will be delivered to young people attending school by community Elders, with the support of teachers, through the transfer of local cultural knowledge and practices with the aim of re-establishing the important cultural and social role of Elders within a community that has suffered the loss of intergenerational transfer of cultural knowledge throughout a 25-year civil war.

METHODS

A formative research phase consisting of interviews with students, teachers, and Elders will inform the intervention and provide data for study objectives. Workshops will be delivered to Elders and teachers in participating schools to build capacity for arts-based, educational workshops to be conducted with students in the classroom. The intervention will be evaluated using a stepped-wedge cluster-randomized trial. Government-funded schools in Omoro District will be randomized into three blocks, each comprised of two primary and two secondary schools (n=1800 students). Schools will be randomly assigned to a crossover sequence from control to intervention condition in 8-week intervals. A process evaluation will be implemented throughout the study to evaluate pathways between intervention development, implementation, and effects.

DISCUSSION

This study will generate comprehensive, in-depth participatory research and evaluation data to inform an effective and sustainable protocol for implementing arts-based HIV stigma interventions for young people in school settings. Findings will have widespread implications in post-conflict settings for HIV prevention, treatment, and care.

A national recruitment strategy for HIV-serodiscordant partners living in Canada for the Positive Plus One study: a mixed-methods study

Background

With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies.

Methods

PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners.

Results

We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner.

Conclusions

Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of “happy couple” bias.

Disclosure of HIV-serodiscordant relationships and association with viral suppression: results from the Positive Plus One study

BACKGROUND

Little is known about the effects of disclosure of HIV-serodiscordant relationships on clinical outcomes. We aimed to evaluate the effect of relationship disclosure on HIV viral suppression, and hypothesized that disclosure by HIV-positive and HIV-negative partners would be associated with viral suppression in the HIV-positive partner.

METHODS

We conducted a Canadian national online and telephone-administered survey of HIV-positive and HIV-negative partners in serodiscordant relationships. The primary outcome was self-reported viral suppression. Multivariable analyses were undertaken using Firth logistic regression.

RESULTS

We recruited 540 participants in current serodiscordant relationships (n = 228 HIV-negative; n = 312 HIV-positive). Similar proportions of HIV-positive and HIV-negative partners disclosed their relationship to healthcare professionals (82% v. 76%, p = 0.13). Among HIV-positive partners, disclosure of the relationship to healthcare professionals increased the odds of viral suppression (aOR = 4.7; CI: 2.13, 10.51) after adjusting for age, education, and relationship turmoil due to HIV. Increasing age (aOR = 1.28; 95% CI = 1.07, 1.55) and education (aOR = 2.43; 95% CI = 1.15, 5.26) were also associated with viral suppression. Among HIV-negative partners, relationship disclosure was not associated with viral suppression and HIV-negative heterosexual men were less likely to report that their HIV-positive partners were virally suppressed (aOR = 0.24; CI: 0.09, 0.61).

CONCLUSIONS

Disclosure of HIV-serodiscordant status by HIV-positive participants to healthcare professionals was associated with increased odds of viral suppression. Similar effects were not evident among HIV-negative participants. Future work should explore factors that empower relationship disclosure and incorporate them into supportive services for HIV-serodiscordant relationships.

Dual pharmaceutical citizenship: Exploring biomedicalization in the daily lives of mixed HIV-serostatus couples in Canada

Positive Plus One is the first large-scale mixed methods study of mixed HIV serostatus couples in Canada. We aimed to understand how biomedicalization i.e., a social process of commodification and expansion of the jurisdiction of medicine over health, influenced the everyday relationships of these couples. We completed 51 semi-structured interviews among a purposive sample of HIV-positive (n = 27) and HIV-negative (n = 24) partners in current or past mixed-serostatus relationships. Participants were recruited after completing an online survey where they consented to be re-contacted for qualitative interviews. Participants represented a diversity of sexual orientations, gender identities, and other sociodemographic characteristics. Drawing on inductive thematic analysis to identify patterns within couples, across serostatus and sexual orientations, we argue that everyday lives of mixed-serostatus couples were shaped by biomedical knowledge and enacted through routine adherence to obtain and maintain viral load undetectability. Our findings illustrated the importance of learning biomedical knowledge for mixed-serostatus couples in this study, the empowering influence of undetectable = untransmittable (UU) discourse, and its role in rendering HIV mundane through routine ART adherence. We introduce the concept of 'dual pharmaceutical citizenship' to underscore a process by which particular biopolitical and biomedical expectations are fulfilled in mixed-serostatus relationships. These findings have implications for people who do not readily accept or have access to biomedical knowledge, particularly when treatment-as-prevention frames a "right" and "wrong" approach to HIV management. Future studies should focus on couples where at least one partner does not readily accept or have access to biomedical knowledge.

Health-care professionals' assessment of a person-centred intervention to empower self-management and health across chronic illness: Qualitative findings from a process evaluation study

Background

Person‐centred care (PCC) empowers patients to manage their chronic illness and promote their health in accordance with their own beliefs, values and preferences. Drawing on health‐care professional's (HCP’s) experiences implementing an empowerment‐focused, person‐centred intervention called the Bodyknowledging Program (BKP), we undertook a process evaluation that aimed to assess the impact on patient health and well‐being.

Methods

We used individual in‐depth interviews and semi‐structured focus groups comprising n = 8 interprofessional HCP who facilitated intervention sessions with n = 58 patients situated in Norwegian specialist care sites. Content analysis was used to analyse the data and summarize major themes.

Results

Health‐care professional interviews revealed four main ways in which the intervention operated in support of health‐related patient outcomes: (i) addressing the whole person; (ii) hope and affirmation; (iii) expanding recovery; and (iv) social support and revitalized relationships. The intervention provided new tools for patients to understand the social, emotional and physical impact of their illness. Health‐care professional reported new insights to facilitate patient engagement and to promote patients’ health.

Conclusions

The Bodyknowledging Program facilitated patient engagement through the promotion of patient‐centred care while developing the patients’ ability to exploit their own resources for effectively managing their health within illness. The process evaluation supported the underlying theoretical basis of the intervention and was suggestive of its potential transferability elsewhere.

Epidemiology and clinical course of COVID-19 in Shanghai, China

Background: Novel coronavirus pneumonia (COVID-19) is prevalent around the world. We aimed to describe epidemiological features and clinical course in Shanghai. Methods: We retrospectively analysed 325 cases admitted at Shanghai Public Health Clinical Center, between January 20 and February 29, 2020. Results: 47.4% (154/325) had visited Wuhan within 2 weeks of illness onset. 57.2% occurred in 67 clusters; 40% were situated within 53 family clusters. 83.7% developed fever during the disease course. Median times from onset to first medical care, hospitalization and negative detection of nucleic acid by nasopharyngeal swab were 1, 4 and 8 days. Patients with mild disease using glucocorticoid tended to have longer viral shedding in blood and feces. At admission, 69.8% presented with lymphopenia and 38.8% had elevated D-dimers. Pneumonia was identified in 97.5% (314/322) of cases by chest CT scan. Severe-critical patients were 8% with a median time from onset to critical disease of 10.5 days. Half required oxygen therapy and 7.1% high-flow nasal oxygen. The case fatality rate was 0.92% with median time from onset to death of 16 days. Conclusion: COVID-19 cases in Shanghai were imported. Rapid identification, and effective control measures helped to contain the outbreak and prevent community transmission.

Low levels of viral suppression among refugees and host nationals accessing antiretroviral therapy in a Kenyan refugee camp

BACKGROUND

Refugees and host nationals who accessed antiretroviral therapy (ART) in a remote refugee camp in Kakuma, Kenya (2011-2013) were compared on outcome measures that included viral suppression and adherence to ART.

METHODS

This study used a repeated cross-sectional design (Round One and Round Two). All adults (≥18 years) receiving care from the refugee camp clinic and taking antiretroviral therapy (ART) for ≥30 days were invited to participate. Adherence was measured by self-report and monthly pharmacy refills. Whole blood was measured on dried blood spots. HIV-1 RNA was quantified and treatment failures were submitted for drug resistance testing. A remedial intervention was implemented in response to baseline testing. The primary outcome was viral load <5000 copies/mL. The two study rounds took place in 2011-2013.

RESULTS

Among eligible adults, 86% (73/85) of refugees and 84% (86/102) of Kenyan host nationals participated in the Round One survey; 60% (44/73) and 58% (50/86) of Round One participants were recruited for Round Two follow-up viral load testing. In Round One, refugees were older than host nationals (median age 36 years, interquartile range, IQR 31, 41 vs 32 years, IQR 27, 38); the groups had similar time on ART (median 147 weeks, IQR 38, 64 vs 139 weeks, IQR 39, 225). There was weak evidence for a difference between proportions of refugees and host nationals who were virologically suppressed (<5000 copies/mL) after 25 weeks on ART (58% vs 43%, p = 0.10) and no difference in the proportions suppressed at Round Two (74% vs 70%, p = 0.66). Mean adherence within each group in Round One was similar. Refugee status was not associated with viral suppression in multivariable analysis (adjusted odds ratio: 1.69, 95% CI 0.79, 3.57; p = 0.17). Among those not suppressed at either timepoint, 69% (9/13) exhibited resistance mutations.

CONCLUSIONS

Virologic outcomes among refugees and host nationals were similar but unacceptably low. Slight improvements were observed after a remedial intervention. Virologic monitoring was important for identifying an underperforming ART program in a remote facility that serves refugees alongside host nationals. This work highlights the importance of careful laboratory monitoring of vulnerable populations accessing ART in remote settings.

Design and implementation of a sexual health intervention for migrant construction workers situated in Shanghai, China

BACKGROUND

China's growing population of internal migrants has exceeded 236 million. Driven by rapid development and urbanization, this extreme population mobility creates opportunities for transmission of HIV and sexually-transmitted infections (STI). Large numbers of rural migrants flock to megacities such as Shanghai in search of employment. Although migrants constitute a key population at heightened risk of acquiring HIV or an STI, there is a lack of easily accessible sexual health services available for them. In response, we designed a short, inexpensive sexual health intervention that sought to improve HIV and STI knowledge, while reducing stigma, risky sexual behaviour, and sexual transmission of HIV and STI among migrant construction workers (MCW) situated in Shanghai, China.

RESULTS

We implemented a three-armed, community-randomized trial spread across three administrative districts of Shanghai. The low-intensity intervention included educational pamphlets. The medium-intensity intervention included pamphlets, posters, and videos. The high-intensity intervention added group and individual counselling sessions. Across 18 construction sites, 1871 MCW were allocated at baseline to receive one intervention condition. Among baseline participants, 1304 workers were retained at 3-months, and 1013 workers were retained at 6-months, representing a total of 579 person-years of follow-up. All workers, regardless of participation, had access to informational materials even if they did not participate in the evaluation. Overall outputs included: 2284 pamphlets distributed, 720 posters displayed, 672 h of video shown, 376 participants accessed group counselling, and 61 participants attended individual counselling sessions. A multivariable analysis of participation found that men (aOR = 2.2; 95 % CI 1.1, 4.1; p = 0.036), workers situated in Huangpu district (aOR = 5.0; 95 % CI 2.6, 9.5; p < 0.001), and those with a middle school education (aOR = 1.9; 95 % CI 1.2, 3.0; p = 0.01) were more likely to have participated in intervention activities.

CONCLUSION

A brief educational intervention that prioritized ease of delivery to a highly mobile workforce was feasible and easily accessed by participants. Routine implementation of sexual health interventions in workplaces that employ migrant labour have the potential to make important contributions toward improving HIV and STI outcomes among migrant workers in China's largest cities.

A scoping review and thematic analysis of social and behavioural research among HIV-serodiscordant couples in high-income settings

BACKGROUND

While HIV incidence has stabilized in many settings, increases in health and wellbeing among many people living with HIV/AIDS suggest that the number of HIV-serodiscordant relationships is growing. Given the deficit of reviews addressing social and behavioural characteristics of HIV-serodiscordant couples within high-income settings, our objective was to understand the scope of the published literature, identify evidence gaps, and suggest future research needs.

METHODS

Ten electronic databases were searched. Studies were included if they were reported in English, used primary data, were from the combination antiretroviral (cART) era (>1996), reported on social or behavioural aspects, included any fraction of primary (i.e., stable) relationships, and were conducted in high-income settings. Studies that identified their unit of analysis as either the dyad or individual member of the couple were included. Studies were coded according to a thematic framework.

RESULTS

Included studies (n = 154) clustered into eight themes: risk behaviours (29%), risk management (26%), reproductive issues (12%), relationship quality (9%), serostatus disclosure (7%), adherence to antiretroviral therapy (7%), vulnerability (5%), and social support (3%). The proportion of studies conducted among heterosexual couples, same-sex male couples, and mixed cohorts were 42%, 34%, and 24%, respectively. Most studies (70%) were conducted in the United States, 70% of all studies were quantitative (including interventions), but only one-third were focused on couples (dyads) where both partners are recruited to a study. Over 25% of studies focused on sexual risk among same-sex male couples.

CONCLUSIONS

Future research efforts should focus on the interrelationship of risk management strategies and relationship quality, social determinants of health and wellbeing, HIV testing, vulnerable populations, reproductive issues among same-sex couples, disclosure of serodiscordant status to social networks, dyadic studies, population-based studies, and interventions to support risk management within couples. Additional population-based studies and studies among marginalized groups would be helpful for targeting research and interventions to couples that are most in need. As HIV-positive partners are typically the link to services and research, innovative ways are needed for reaching out to HIV-negative partners. Our review suggests that significantly more research is needed to understand the social and behavioural contexts of HIV-serodiscordant relationships.

Impact evaluation of a community-based intervention to reduce risky sexual behaviour among female sex workers in Shanghai, China

Background

Female sex workers (FSWs) are at risk for sexually transmitted infections (STIs), including HIV. We implemented an HIV/STI preventive intervention among FSWs in Shanghai that aimed to increase condom use, improve HIV knowledge, and reduce STI and HIV incidence.

Methods

From six districts in Shanghai, 750 randomly selected venue-based FSWs were allocated to either a behavioural intervention or control group. In the intervention and control groups, 221 and 278 participants, respectively, had at least one follow-up at three or six months. In analysis, we randomly selected 57 lost to follow-up cases in the intervention group and imputed baseline values to equalize the arms at n = 278 (74.1% follow-up rate in each group). The impacts of the intervention on condom use, HIV/STI risk perception and knowledge, and STI incidence were assessed using either a logistic or linear model, adjusting for the baseline measure of the outcome and venue type.

Results

The intervention improved consistent condom use with any partner type in the previous month (AOR = 2.09, 95% CI, 1.43-3.04, p = 0.0001). Consistent condom use with clients in the three most recent sex acts increased in both arms, and with primary partners in the intervention arm, but there was no difference between groups after adjusting for baseline condom use and venue type. There were no differences in cumulative incidence of any STI (i.e., chlamydia, gonorrhoea, syphilis) between groups. HIV transmission knowledge (p = 0.0001), condom use skill (p = 0.0421), and self-efficacy for using condoms (p = 0.0071) were improved by the intervention. HIV-related stigma declined (p = 0.0119) and HIV and STI risk perception were improved (4.6 to 13.9%, and 9.4 to 20.0%, respectively). The intervention was associated with these improvements after adjusting for the baseline measure and venue type.

Conclusion

Following a preventive intervention among Shanghai FSWs, our findings demonstrate that a simple, community-based educational intervention improved overall condom use, HIV and STI knowledge, and attitudes in relation to HIV/AIDS. The intervention should be implemented widely after tailoring educational materials regarding condom negotiation with different partner types (i.e., commercial sex clients and primary partners).

Bounded agency in humanitarian settings: a qualitative study of adherence to antiretroviral therapy among refugees situated in Kenya and Malaysia

HIV-positive refugees confront a variety of challenges in accessing and adhering to antiretroviral therapy (ART) and attaining durable viral suppression; however, there is little understanding of what these challenges are, how they are navigated, or how they may differ across humanitarian settings. We sought to document and examine accounts of the threats, barriers and facilitators experienced in relation to HIV treatment and care and to conduct comparisons across settings. We conducted semi-structured interviews among a purposive sample of 14 refugees attending a public, urban HIV clinic in Kuala Lumpur, Malaysia (July-September 2010), and 12 refugees attending a camp-based HIV clinic in Kakuma, Kenya (February-March 2011). We used framework methods and between-case comparison to analyze and interpret the data, identifying social and environmental factors that influenced adherence. The multiple issues that threatened adherence to antiretroviral therapy or precipitated actual adherence lapses clustered into three themes: "migration", "insecurity", and "resilience". The migration theme included issues related to crossing borders and integrating into treatment systems upon arrival in a host country. Challenges related to crossing borders were reported in both settings, but threats pertaining to integration into, and navigation of, a new health system were exclusive to the Malaysian setting. The insecurity theme included food insecurity, which was most commonly reported in the Kenyan setting; health systems insecurity, reported in both settings; and emotional insecurity, which was most common in the Kenyan setting. Resilient processes were reported in both settings. We drew on the concept of "bounded agency" to argue that, despite evidence of personal and community resilience, these processes were sometimes insufficient for overcoming social and environmental barriers to adherence. In general, interventions might aim to bolster individuals' range of action with targeted support that bolsters resilient processes. Specific interventions are needed to address locally-based food and health system insecurities.

Antiretroviral therapy for refugees and internally displaced persons: a call for equity

Joshua Mendelsohn and colleagues discuss the moral, legal, and public health principles and recent evidence that strongly suggest that refugees and internally displaced people should have equal access to HIV treatment and support as host nationals and give detailed recommendations for refugees and internally displaced people accessing antiretroviral therapy in stable settings.

Adherence to antiretroviral therapy and treatment outcomes among conflict-affected and forcibly displaced populations: a systematic review

BACKGROUND

Optimal adherence to highly active antiretroviral therapy (HAART) is required to promote viral suppression and to prevent disease progression and mortality. Forcibly displaced and conflict-affected populations may face challenges succeeding on HAART. We performed a systematic review of the literature on adherence to HAART and treatment outcomes in these groups, including refugees and internally-displaced persons (IDPs), assessed the quality of the evidence and suggest a future research program.

METHODS

Medline, Embase, and Global Health databases for 1995-2011 were searched using the Ovid platform. A backward citation review of subsequent work that had cited the Ovid results was performed using the Web of Science database. ReliefWeb and Médecins Sans Frontières (MSF) websites were searched for additional grey literature.

RESULTS AND CONCLUSION

We screened 297 records and identified 17 reports covering 15 quantitative and two qualitative studies from 13 countries. Three-quarters (11/15) of the quantitative studies were retrospective studies based on chart review; five studies included <100 clients. Adherence or treatment outcomes were reported in resettled refugees, conflict-affected persons, internally-displaced persons (IDPs), and combinations of refugees, IDPs and other foreign-born persons. The reviewed reports showed promise for conflict-affected and forcibly-displaced populations; the range of optimal adherence prevalence reported was 87-99.5%. Treatment outcomes, measured using virological, immunological and mortality estimates, were good in relation to non-affected groups. Given the diversity of settings where forcibly-displaced and conflict-affected persons access ART, further studies on adherence and treatment outcomes are needed to support scale-up and provide evidence-based justifications for inclusion of these vulnerable groups in national treatment plans. Future studies and program evaluations should focus on systematic monitoring of adherence and treatment interruptions by using facility-based pharmacy records, understanding threats to optimal adherence and timely linkage to care throughout the displacement cycle, and testing interventions designed to support adherence and treatment outcomes in these settings.
