Understanding adaptive responses in PrEP service delivery in Belgian HIV clinics: a multiple case study using an implementation science framework

INTRODUCTION

In Belgium, oral HIV pre-exposure prophylaxis (PrEP) is primarily provided in specialized clinical settings. Optimal implementation of PrEP services can help to substantially reduce HIV transmission. However, insights into implementation processes, and their complex interactions with local context, are limited. This study examined factors that influence providers' adaptive responses in the implementation of PrEP services in Belgian HIV clinics.

METHODS

We conducted a qualitative multiple case study on PrEP care implementation in eight HIV clinics. Thirty-six semi-structured interviews were conducted between January 2021 and May 2022 with a purposive sample of PrEP care providers (e.g. physicians, nurses, psychologists), supplemented by 50 hours of observations of healthcare settings and clinical interactions. Field notes from observations and verbatim interview transcripts were thematically analysed guided by a refined iteration of extended Normalisation Process Theory.

RESULTS

Implementing PrEP care in a centralized service delivery system required considerable adaptive capacity of providers to balance the increasing workload with an adequate response to PrEP users' individual care needs. As a result, clinic structures were re-organized to allow for more efficient PrEP care processes, compatible with other clinic-level priorities. Providers adapted clinical and policy norms on PrEP care (e.g. related to PrEP prescribing practices and which providers can deliver PrEP services), to flexibly tailor care to individual clients' situations. Interprofessional relationships were reconfigured in line with organizational and clinical adaptations; these included task-shifting from physicians to nurses, leading them to become increasingly trained and specialized in PrEP care. As nurse involvement grew, they adopted a crucial role in responding to PrEP users' non-medical needs (e.g. providing psychosocial support). Moreover, clinicians' growing collaboration with sexologists and psychologists, and interactions with PrEP users' family physician, became crucial in addressing complex psychosocial needs of PrEP clients, while also alleviating the burden of care on busy HIV clinics.

CONCLUSIONS

Our study in Belgian HIV clinics reveals that the implementation of PrEP care presents a complex-multifaceted-undertaking that requires substantial adaptive work to ensure seamless integration within existing health services. To optimize integration in different settings, policies and guidelines governing PrEP care implementation should allow for sufficient flexibility and tailoring according to respective local health systems.

Methods and Measures to Assess Health Care Provider Behavior and Behavioral Determinants in Reproductive, Maternal, Newborn, and Child Health: A Rapid Review

BACKGROUND

Health care provider behavior is the outcome of a complex set of factors that are both internal and external to the provider. Social and behavior change (SBC) programs are increasingly engaging providers and introducing strategies to improve their service delivery. However, there is limited understanding of methods and measures applied to assess provider behavioral outcomes and strengthen provider behavior change programming.

METHODS

Using PubMed, we conducted a rapid review of published research on behaviors of health workers providing reproductive, maternal, newborn, and child health services in low- and middle-income countries (2010-2021). Information on study identifiers (e.g., type of provider), select domains from Green and Kreuter's PRECEDE-PROCEED framework (e.g., predisposing factors such as attitudes), study characteristics (e.g., study type and design), and evidence of theory-driven research were extracted from a final sample of articles (N=89) and summarized.

RESULTS

More than 80% of articles were descriptive/formative and examined knowledge, attitudes, and practice, mostly related to family planning. Among the few evaluation studies, training-focused interventions to increase provider knowledge or improve competency in providing a health service were dominant. Research driven by behavioral theory was observed in only 3 studies. Most articles (75%) focused on the quality of client-provider interaction, though topics and modes of measurement varied widely. Very few studies incorporated a validated scale to measure underlying constructs, such as attitudes and beliefs, and how these may be associated with provider behaviors.

CONCLUSION

A need exists for (1) theory-driven approaches to designing and measuring provider behavior change interventions and (2) measurement that addresses important internal and structural factors related to a provider's behavior (beyond knowledge-enhancing training approaches). Additional investment in implementation research is also needed to better understand which SBC approaches are shifting provider behavior and improving client-provider interactions. Finally, theory-driven approaches could help develop empirically measurable and comparable outcomes.

Integration measurement and its applications in low- and middle-income country health systems: a scoping review

BACKGROUND

Despite growing interest in and commitment to integration, or integrated care, the concept is ill-defined and the resulting evidence base fragmented, particularly in low- and middle-income countries (LMICs). Underlying this challenge is a lack of coherent approaches to measure the extent of integration and how this influences desired outcomes. The aim of this scoping review is to identify measurement approaches for integration in LMICs and map them for future use.

METHODS

Arksey and O'Malley's framework for scoping reviews was followed. We conducted a systematic search of peer-reviewed literature measuring integration in LMICs across three databases and screened identified papers by predetermined inclusion and exclusion criteria. A modified version of the Rainbow Model for Integrated Care guided charting and analysis of the data.

RESULTS

We included 99 studies. Studies were concentrated in the Africa region and most frequently focused on the integration of HIV care with other services. A range of definitions and methods were identified, with no single approach for the measurement of integration dominating the literature. Measurement of clinical integration was the most common, with indicators focused on measuring receipt of two or more services provided at a single point of time. Organizational and professional integration indicators were focused on inter- and intra-organizational communication, collaboration, coordination, and continuity of care, while functional integration measured common information systems or patient records. Gaps were identified in measuring systems and normative integration. Few tools were validated or publicly available for future use.

CONCLUSION

We identified a wide range of recent approaches used to measure integration in LMICs. Our findings underscore continued challenges with lack of conceptual cohesion and fragmentation which limits how integration is understood in practice.

Healthcare workers' perceptions and experiences of primary healthcare integration: a scoping review of qualitative evidence

BACKGROUND

Primary healthcare (PHC) integration has been promoted globally as a tool for health sector reform and universal health coverage (UHC), especially in low-resource settings. However, for a range of reasons, implementation and impact remain variable. PHC integration, at its simplest, can be considered a way of delivering PHC services together that sometimes have been delivered as a series of separate or 'vertical' health programmes. Healthcare workers are known to shape the success of implementing reform interventions. Understanding healthcare worker perceptions and experiences of PHC integration can therefore provide insights into the role healthcare workers play in shaping implementation efforts and the impact of PHC integration. However, the heterogeneity of the evidence base complicates our understanding of their role in shaping the implementation, delivery, and impact of PHC integration, and the role of contextual factors influencing their responses.

OBJECTIVES

To map the qualitative literature on healthcare workers' perceptions and experiences of PHC integration to characterise the evidence base, with a view to better inform future syntheses on the topic.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 28 July 2020. We did not search for grey literature due to the many published records identified.

SELECTION CRITERIA

We included studies with qualitative and mixed methods designs that reported on healthcare worker perceptions and experiences of PHC integration from any country. We excluded settings other than PHC and community-based health care, participants other than healthcare workers, and interventions broader than healthcare services. We used translation support from colleagues and Google Translate software to screen non-English records. Where translation was not feasible we categorised these records as studies awaiting classification.

DATA COLLECTION AND ANALYSIS

For data extraction, we used a customised data extraction form containing items developed using inductive and deductive approaches. We performed independent extraction in duplicate for a sample on 10% of studies allowed for sufficient agreement to be reached between review authors. We analysed extracted data quantitatively by counting the number of studies per indicator and converting these into proportions with additional qualitative descriptive information. Indicators included descriptions of study methods, country setting, intervention type, scope and strategies, implementing healthcare workers, and client target population.

MAIN RESULTS

The review included 184 studies for analysis based on 191 included papers. Most studies were published in the last 12 years, with a sharp increase in the last five years. Studies mostly employed methods with cross-sectional qualitative design (mainly interviews and focus group discussions), and few used longitudinal or ethnographic (or both) designs. Studies covered 37 countries, with close to an even split in the proportions of high-income countries (HICs) and low- and middle-income countries (LMICs). There were gaps in the geographical spread for both HICs and LMICs and some countries were more dominant, such as the USA for HICs, South Africa for middle-income countries, and Uganda for low-income countries. Methods were mainly cross-sectional observational studies with few longitudinal studies. A minority of studies used an analytical conceptual model to guide the design, implementation, and evaluation of the integration study. The main finding was the various levels of diversity found in the evidence base on PHC integration studies that examined healthcare workers' perceptions and experiences. The review identified six different configurations of health service streams that were being integrated and these were categorised as: mental and behavioural health; HIV, tuberculosis (TB) and sexual reproductive health; maternal, women, and child health; non-communicable diseases; and two broader categories, namely general PHC services, and allied and specialised services. Within the health streams, the review mapped the scope of the interventions as full or partial integration. The review mapped the use of three different integration strategies and categorised these as horizontal integration, service expansion, and service linkage strategies. The wide range of healthcare workers who participated in the implementation of integration interventions was mapped and these included policymakers, senior managers, middle and frontline managers, clinicians, allied healthcare professionals, lay healthcare workers, and health system support staff. We mapped the range of client target populations.

AUTHORS' CONCLUSIONS

This scoping review provides a systematic, descriptive overview of the heterogeneity in qualitative literature on healthcare workers' perceptions and experience of PHC integration, pointing to diversity with regard to country settings; study types; client populations; healthcare worker populations; and intervention focus, scope, and strategies. It would be important for researchers and decision-makers to understand how the diversity in PHC integration intervention design, implementation, and context may influence how healthcare workers shape PHC integration impact. The classification of studies on the various dimensions (e.g. integration focus, scope, strategy, and type of healthcare workers and client populations) can help researchers to navigate the way the literature varies and for specifying potential questions for future qualitative evidence syntheses.

The classification of studies on the various dimensions (e.g. integration focus, scope, strategy, and type of healthcare workers and client populations) can help researchers to navigate the way the literature varies and for specifying potential questions for future qualitative evidence syntheses.

The Application of Systems Thinking to the Prevention and Control of Sexually Transmissible Infections among Adolescents and Adults: A Scoping Review

Systems thinking is a mechanism for making sense of complex systems that challenge linear explanations of cause-and-effect. While the prevention and control of sexually transmissible infections (STIs) has been identified as an area that may benefit from systems-level analyses, no review on the subject currently exists. The aim of this study is to conduct a scoping review to identify literature in which systems thinking has been applied to the prevention and control of STIs among adolescent and adult populations. Joanna Briggs Institute guidelines for the conduct of scoping reviews were followed. Five databases were searched for English-language studies published after 2011. A total of n = 6102 studies were screened against inclusion criteria and n = 70 were included in the review. The majority of studies (n = 34) were conducted in African nations. Few studies focused on priority sub-populations, and 93% were focused on HIV (n = 65). The most commonly applied systems thinking method was system dynamics modelling (n = 28). The review highlights areas for future research, including the need for more STI systems thinking studies focused on: (1) migrant and Indigenous populations; (2) conditions such as syphilis; and (3) innovations such as pre-exposure prophylaxis and at-home testing for HIV. The need for conceptual clarity around 'systems thinking' is also highlighted.

Implementation considerations for non-communicable disease-related integration in primary health care: a rapid review of qualitative evidence

BACKGROUND

Integrated delivery of primary health care (PHC) services is a health reform recommended for achieving ambitious targets of the Sustainable Development Goals and Universal Health Coverage, responding to growing challenges of managing non-communicable and multimorbidity. However, more evidence is needed on effective implementation of PHC integration in different country settings.

OBJECTIVE

This rapid review synthesized qualitative evidence on implementation factors affecting integration of non-communicable disease (NCD) into PHC, from the perspective of implementers. The review contributes evidence to inform the World Health Organizations' guidance on integration of NCD control and prevention to strengthen health systems.

METHOD

The review was guided by standard methods for conducting rapid systematic reviews. Data analysis was guided by the SURE and WHO health system building blocks frameworks. We used Confidence in the Evidence of Reviews of Qualitative Research (GRADE-CERQual) to assess the confidence of the main findings.

RESULTS

The review identified 81 records eligible for inclusion, from 595 records screened. We sampled 20 studies for analysis (including 3 from expert recommendations). Studies covered a wide range of countries (27 countries from 6 continents), the majority from low-and middle-income countries (LMICs), with a diverse set of NCD-related PHC integration combinations and implementation strategies. The main findings were categorised into three overarching themes and several sub-themes. These are, A: Policy alignment and governance, B: Health systems readiness, intervention compatibility and leadership, and C: Human resource management, development, and support. The three overarching findings were assessed as each having a moderate level of confidence.

CONCLUSION

The review findings present insights on how health workers responses may be shaped by the complex interaction of individual, social, and organizational factors that may be specific to the context of the intervention, the importance of cross-cutting influences such as policy alignment, supportive leadership and health systems constraints, knowledge that can inform the development of future implementation strategies and implementation research.

Use of implementation science to advance family planning programs in low- and middle-income countries: A systematic review

Objective

As environmental and economic pressures converge with demands to achieve sustainability development goals, low- and middle-income countries (LMIC) increasingly require strategies to strengthen and scale-up evidence-based practices (EBP) related to family planning (FP). Implementation science (IS) can help these efforts. The purpose of this article is to elucidate patterns in the use of IS in FP research and identify ways to maximize the potential of IS to advance FP in LMIC.

Design and methods

We conducted a systematic review that describes how IS concepts and principles have been operationalized in LMIC FP research published from 2007-2021. We searched six databases for implementation studies of LMIC FP interventions. Our review synthesizes the characteristics of implementation strategies and research efforts used to enhance the performance of FP-related EBP in these settings, identifying gaps, strengths and lessons learned.

Results

Four-hundred and seventy-two studies were eligible for full-text review. Ninety-two percent of studies were carried out in one region only, whereas 8 percent were multi-country studies that took place across multiple regions. 37 percent of studies were conducted in East Africa, 21 percent in West and Central Africa, 19 percent in Southern Africa and South Asia, respectively, and fewer than 5 percent in other Asian countries, Latin America and Middle East and North Africa, respectively. Fifty-four percent were on strategies that promoted individuals' uptake of FP. Far fewer were on strategies to enhance the coverage, implementation, spread or sustainability of FP programs. Most studies used quantitative methods only and evaluated user-level outcomes over implementation outcomes. Thirty percent measured processes and outcomes of strategies, 15 percent measured changes in implementation outcomes, and 31 percent report on the effect of contextual factors. Eighteen percent reported that they were situated within decision-making processes to address locally identified implementation issues. Fourteen percent of studies described measures to involve stakeholders in the research process. Only 7 percent of studies reported that implementation was led by LMIC delivery systems or implementation partners.

Conclusions

IS has potential to further advance LMIC FP programs, although its impact will be limited unless its concepts and principles are incorporated more systematically. To support this, stakeholders must focus on strategies that address a wider range of implementation outcomes; adapt research designs and blend methods to evaluate outcomes and processes; and establish collaborative research efforts across implementation, policy, and research domains. Doing so will expand opportunities for learning and applying new knowledge in pragmatic research paradigms where research is embedded in usual implementation conditions and addresses critical issues such as scale up and sustainability of evidence-informed FP interventions.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, identifier: CRD42020199353.

Integrated Delivery of Family Planning and Childhood Immunisation Services: A Qualitative Study of Factors Influencing Service Responsiveness in Malawi

Evidence from several countries in sub-Saharan Africa suggests that the integration of family planning (FP) with childhood immunization services can help reduce the unmet need for FP among postpartum women without undermining the uptake of immunizations. However, the quality and responsiveness of FP services that are integrated with childhood immunizations remain understudied. A qualitative study was conducted in two districts of Malawi, which examined the factors influencing the responsiveness of FP services that were integrated with childhood immunizations in monthly public outreach clinics. Semi-structured interviews with clients (n = 23) and FP providers (n = 10) and a clinic audit were carried out in six clinics. Hardware (material) and software (relational) factors influencing service responsiveness were identified through thematic and framework analyses of interview transcripts, and clinic characteristics were summarized from the audit data to contextualize the qualitative findings. Overall, 13 factors were found to influence service responsiveness in terms of the ease of access, choice of provider, environment, service continuity, confidentiality, communication, dignity and FP counselling afforded to clients. Among these factors, hardware deficiencies, including the absence of a dedicated building for the provision of FP services and the lack of FP commodities in clinics, were perceived to negatively affect service responsiveness. Crucially, the providers’ use of their agency to alter the delivery of services was found to mitigate the negative effects of some hardware deficits on the ease of access, choice of provider, environment and confidentiality experienced by clients. This study contributes to an emerging recognition that providers can offset the effect of hardware deficiencies when services are integrated if they are afforded sufficient flexibility to make independent decisions. Consideration of software elements in the design and delivery of FP services that are integrated with childhood immunizations is therefore critical to optimize the responsiveness of these services.

Perceptions of quality and the integrated delivery of family planning with childhood immunisation services in Kenya and Uganda

The integration of family planning (FP) with childhood immunisations is considered a promising approach to addressing postpartum women's unmet need for FP in resource limited settings. This study set out to examine client and health provider perceptions of the quality of FP services that were integrated with childhood immunisations in Kenya and Uganda. Semi-structured interviews with clients (n = 30) and health providers (n = 27) were conducted in 16 rural health facilities. Interviews centred on the respondents' experiences receiving/delivering FP services, their interactions with providers/clients, and their views on the quality of FP services. Client and provider perceptions of quality were compared through a thematic analysis of interview transcripts, and findings were synthesised using Jain and Hardee's revised FP Quality of Care Framework. Using audit data, health facility characteristics and resources were also summarised through descriptive statistics to contextualise the qualitative findings. The dignity and respect experienced by clients was central to the respondents' perceptions of quality. These two dimensions were not conceptualised as distinct facets of quality, but were instead perceived to be a product of the 1) access to needed services, 2) choice of contraceptives, 3) interpersonal communication, 4) information, and 5) confidentiality afforded to clients. Additionally, clients and providers alike believed that the integration of FP services with childhood immunisations had a positive effect on clients' access to needed services and on the confidentiality they experienced in a context where modern contraceptive use was stigmatised and where a lack of support from some husbands impeded access to FP services. Understanding clients' and providers' conceptualisation of quality is critical to the design of high quality and client-centred integrated FP services.

Integrating HIV services and other health services: A systematic review and meta-analysis

BACKGROUND

Integration of HIV services with other health services has been proposed as an important strategy to boost the sustainability of the global HIV response. We conducted a systematic and comprehensive synthesis of the existing scientific evidence on the impact of service integration on the HIV care cascade, health outcomes, and cost-effectiveness.

METHODS AND FINDINGS

We reviewed the global quantitative empirical evidence on integration published between 1 January 2010 and 10 September 2021. We included experimental and observational studies that featured both an integration intervention and a comparator in our review. Of the 7,118 unique peer-reviewed English-language studies that our search algorithm identified, 114 met all of our selection criteria for data extraction. Most of the studies (90) were conducted in sub-Saharan Africa, primarily in East Africa (55) and Southern Africa (24). The most common forms of integration were (i) HIV testing and counselling added to non-HIV services and (ii) non-HIV services added to antiretroviral therapy (ART). The most commonly integrated non-HIV services were maternal and child healthcare, tuberculosis testing and treatment, primary healthcare, family planning, and sexual and reproductive health services. Values for HIV care cascade outcomes tended to be better in integrated services: uptake of HIV testing and counselling (pooled risk ratio [RR] across 37 studies: 1.67 [95% CI 1.41-1.99], p < 0.001), ART initiation coverage (pooled RR across 19 studies: 1.42 [95% CI 1.16-1.75], p = 0.002), time until ART initiation (pooled RR across 5 studies: 0.45 [95% CI 0.20-1.00], p = 0.050), retention in HIV care (pooled RR across 19 studies: 1.68 [95% CI 1.05-2.69], p = 0.031), and viral suppression (pooled RR across 9 studies: 1.19 [95% CI 1.03-1.37], p = 0.025). Also, treatment success for non-HIV-related diseases and conditions and the uptake of non-HIV services were commonly higher in integrated services. We did not find any significant differences for the following outcomes in our meta-analyses: HIV testing yield, ART adherence, HIV-free survival among infants, and HIV and non-HIV mortality. We could not conduct meta-analyses for several outcomes (HIV infections averted, costs, and cost-effectiveness), because our systematic review did not identify sufficient poolable studies. Study limitations included possible publication bias of studies with significant or favourable findings and comparatively weak evidence from some world regions and on integration of services for key populations in the HIV response.

CONCLUSIONS

Integration of HIV services and other health services tends to improve health and health systems outcomes. Despite some scientific limitations, the global evidence shows that service integration can be a valuable strategy to boost the sustainability of the HIV response and contribute to the goal of 'ending AIDS by 2030', while simultaneously supporting progress towards universal health coverage.

Community-level integration of health services and community health workers' agency in Malawi

Despite a large literature on integration of health services, there is a dearth of scholarship assessing service integration in its totality at the community level. Similarly, across the wide evidence base on community health workers (CHWs), there is little that analyses the ways in which they interact with both formal and informal structures and how these interactions shape their agency and ultimately the delivery of integrated services. A better understanding of agency in the work of CHWs would help health systems, policy makers and practitioners to better design and support the delivery of community-level integrated health packages to improve health outcomes. In this study, we explored the agency of CHWs in Malawi known as Health Surveillance Assistants (HSAs). We used qualitative methods: participant observation, in-depth interviews, and focus group discussions between July and October 2018. Overall, the ethnographic study utilised actors-centred frameworks (structuration theory and street-level bureaucracy). The study findings unravel the complexities involving HSAs' agency shaped by health system structures (staffing, infrastructure, drugs, and supplies) and informal structures (community relations, local power structures, gendered-household relations) which narrowed or widened their discretionary decision-making space. The flexibility of HSAs was a distinctive feature in their work, but they developed other coping mechanisms: task shifting, teamwork, creative community engagement, and referrals to deliver integrated maternal and child health services. HSAs' unique position as community-based providers meant they needed to consider diverse factors that constrained or facilitated their work. Overall, we argue that HSAs need to be fully involved in the design of community-level integrated health programmes. There should be a consideration to address both informal and formal structures that together shape agency. Additionally, CHWs' flexibility and agency to make locally informed decisions must be protected and maintained because it enhances their ability to deliver essential health services.

Development of integration indexes to determine the extent of family planning and child immunization services integration in health facilities in urban areas of Nigeria

Background

Integrating family planning into child immunization services may address unmet need for contraception by offering family planning information and services to postpartum women during routine child immunization visits. However, policies and programs promoting integration are often based on insubstantial or conflicting evidence about its effects on service delivery and health outcomes. While integration models vary, many studies measure integration as binary (a facility is integrated or not) rather than a multidimensional and varying continuum. It is thus challenging to ascertain the determinants and effects of integrated service delivery. This study creates Facility and Provider Integration Indexes, which measure capacity to support integrated family planning and child immunization services and applies them to analyze the extent of integration across 400 health facilities.

Methods

This study utilizes cross-sectional health facility (N = 400; 58% hospitals, 42% primary healthcare centers) and healthcare provider (N = 1479) survey data that were collected in six urban areas of Nigeria for the impact evaluation of the Nigerian Urban Reproductive Health Initiative. Principal Component Analysis was used to develop Provider and Facility Integration Indexes that estimate the extent of integration in these health facilities. The Provider Integration Index measures provider skills and practices that support integrated service delivery while the Facility Integration Index measures facility norms that support integrated service delivery. Index scores range from zero (low) to ten (high).

Results

Mean Provider Integration Index score is 5.42 (SD 3.10), and mean Facility Integration Index score is 6.22 (SD 2.72). Twenty-three percent of facilities were classified as having low Provider Integration scores, 32% as medium, and 45% as high. Fourteen percent of facilities were classified as having low Facility Integration scores, 38% as medium, and 48% as high.

Conclusion

Many facilities in our sample have achieved high levels of integration, while many others have not. Results suggest that using more nuanced measures of integration may (a) more accurately reflect true variation in integration within and across health facilities, (b) enable more precise measurement of the determinants or effects of integration, and (c) provide more tailored, actionable information about how best to improve integration. Overall, results reinforce the importance of utilizing more nuanced measures of facility-level integration.

What mechanisms drive uptake of family planning when integrated with childhood immunisation in Ethiopia? A realist evaluation

Background

Maternal and child health are key priorities among the Sustainable Development Goals, which include a particular focus on reducing morbidity and mortality among women of reproductive age, newborns, and children under the age of five. Two components of maternal and child health are family planning (FP) and immunisation. Providing these services through an integrated delivery system could increase the uptake of vaccines and modern contraceptive methods (MCMs) particularly during the post-partum period.

Methods

A realist evaluation was conducted in two woredas in Ethiopia to determine the key mechanisms and their triggers that drive successful implementation and service uptake of an intervention of integrated delivery of immunisations and FP. The methodological approach included the development of an initial programme theory and the selection of relevant, published implementation related theoretical frameworks to aid organisation and cumulation of findings. Data from 23 semi-structured interviews were then analysed to determine key empirical mechanisms and drivers and to test the initial programme theory. These mechanisms were mapped against published theoretical frameworks and a revised programme theory comprised of context-mechanism-outcome configurations was developed. A critique of theoretical frameworks for abstracting empirical mechanisms was also conducted.

Results

Key contextual factors identified were: the use of trained Health Extension Workers (HEWs) to deliver FP services; a strong belief in values that challenged FP among religious leaders and community members; and a lack of support for FP from male partners based on religious values. Within these contexts, empirical mechanisms of acceptability, access, and adoption of innovations that drove decision making and intervention outcomes among health workers, religious leaders, and community members were identified to describe intervention implementation.

Conclusions

Linking context and intervention components to the mechanisms they triggered helped explain the intervention outcomes, and more broadly how and for whom the intervention worked. Linking empirical mechanisms to constructs of implementation related theoretical frameworks provided a level of abstraction through which findings could be cumulated across time, space, and conditions by theorising middle-range mechanisms.

Health systems software factors and their effect on the integration of sexual and reproductive health and HIV services

Despite a large and growing body of literature on sexual and reproductive health (SRH) and HIV integration, the drivers of integration of SRH and HIV services, from a health systems perspective, are not well understood. These drivers include complex so-called hardware (structural and resource) and software (values and norms, and human relations and interactions) factors. Two groups of software factors emerge as essential enablers of effective integration of SRH and HIV services that often interact with systems hardware: (1) leadership, management, and governance processes and (2) provider motivation, agency, and relationships. Evidence suggests the potential for software elements that are essential enablers to overcome some of the obstacles posed by the non-integration of health system hardware elements (eg, financing, guidelines, and commodity supplies). These enabling factors include flexible decision making, inclusive management, and support in motivating frontline staff who can work with agency as a team. Improved software, even within constrained hardware (especially in low-income and middle-income countries), can directly contribute to improved SRH and HIV service delivery.

Uptake of long acting reversible contraception following integrated couples HIV and fertility goal-based family planning counselling in Catholic and non-Catholic, urban and rural government health centers in Kigali, Rwanda

BACKGROUND

When integrated with couples' voluntary HIV counselling and testing (CVCT), family planning including long acting reversible contraceptives (LARC) addresses prongs one and two of prevention of mother-to-child transmission (PMTCT).

METHODS

In this observational study, we enrolled equal numbers of HIV concordant and discordant couples in four rural and four urban clinics, with two Catholic and two non-Catholic clinics in each area. Eligible couples were fertile, not already using a LARC method, and wished to limit or delay fertility for at least 2 years. We provided CVCT and fertility goal-based family planning counselling with the offer of LARC and conducted multivariate analysis of clinic, couple, and individual predictors of LARC uptake.

RESULTS

Of 1290 couples enrolled, 960 (74%) selected LARC: Jadelle 5-year implant (37%), Implanon 3-year implant (26%), or copper intrauterine device (IUD) (11%). Uptake was higher in non-Catholic clinics (85% vs. 63% in Catholic clinics, p < 0.0001), in urban clinics (82% vs. 67% in rural clinics, p < 0.0001), and in HIV concordant couples (79% vs. 70% of discordant couples, p = .0005). Religion of the couple was unrelated to clinic religious affiliation, and uptake was highest among Catholics (80%) and lowest among Protestants (70%) who were predominantly Pentecostal. In multivariable analysis, urban location and non-Catholic clinic affiliation, Catholic religion of woman or couple, younger age of men, lower educational level of both partners, non-use of condoms or injectable contraception at enrollment, prior discussion of LARC by the couple, and women not having concerns about negative side effects of implant were associated with LARC uptake.

CONCLUSIONS

Fertility goal-based LARC recommendations combined with couples' HIV counselling and testing resulted in a high uptake of LARC methods, even among discordant couples using condoms for HIV prevention, in Catholic clinics, and in rural populations. This model successfully integrates prevention of HIV and unplanned pregnancy.

Integration of HIV testing services into family planning services: a systematic review

BACKGROUND

Despite significant interest in integrating sexual and reproductive health (SRH) services into HIV services, less attention has been paid to linkages in the other direction. Where women and girls are at risk of HIV, offering HIV testing services (HTS) during their visits to family planning (FP) services offers important opportunities to address both HIV and unwanted pregnancy needs simultaneously.

METHODS

We conducted a systematic review of studies comparing FP services with integrated HTS to those without integrated HTS or with a lower level of integration (e.g., referral versus on-site services), on the following outcomes: uptake/counseling/offer of HTS, new cases of HIV identified, linkage to HIV care and treatment, dual method use, client satisfaction and service quality, and provider knowledge and attitudes about integrating HTS. We searched three online databases and included studies published in a peer-reviewed journal prior to the search date of June 20, 2017.

RESULTS

Of 530 citations identified, six studies ultimately met the inclusion criteria. Three studies were conducted in Kenya, and one each in Uganda, Swaziland, and the USA. Most were in FP clinics. Three were from the Integra Initiative. Overall rigor was moderate, with one cluster-randomized trial. HTS uptake was generally higher with integrated sites versus comparison or pre-integration sites, including in adjusted analyses, though outcomes varied slightly across studies. One study found that women at integrated sites were more likely to have high satisfaction with services, but experienced longer waiting times. One study found a small increase in HIV seropositivity among female patients testing after full integration, compared to a dedicated HIV tester. No studies comparatively measured linkage to HIV care and treatment, dual method use, or provider knowledge/attitudes.

CONCLUSIONS

Global progress and success for reaching SRH and HIV targets depends on progress in sub-Saharan Africa, where women bear a high burden of both unintended pregnancy and sexually transmitted infections, including HIV. While the evidence base is limited, it suggests that integration of HTS into FP services is feasible and has potential for positive joint outcomes. The success and scale-up of this approach will depend on population needs and health system factors.

New partnerships, new perspectives: The relevance of sexual and reproductive health and rights for sustainable development

In the light of the opportunities presented by the Sustainable Development Goals (SDGs) debate is being reignited to understand the connections between human population dynamics (including rapid population growth) and sustainable development. Sustainable development is seriously affected by human population dynamics yet programme planners too often fail to consider them in development programming, casting doubt on the sustainability of such programming. Some innovative initiatives are attempting to cross sector boundaries once again, such as the Population Health and Environment (PHE) programmes, which are integrated programmes encompassing family planning service provision with broader public health services and environmental conservation activities. These initiatives take on greater prominence in the context of the SDGs since they explicitly seek to provide cross-sector programming and governance to improve both human and planetary wellbeing. Yet such initiatives remain under-researched and under promoted.

Integrated and differentiated methadone and HIV care for people who use drugs: a qualitative study in Kenya with implications for implementation science

Integrating methadone and HIV care is a priority in many low- and middle-income settings experiencing a growing challenge of HIV epidemics linked to injecting drug use. There is as yet little understanding of how to integrate methadone and HIV care in these settings and how such services can be implemented; such a gap reflects, in part, limitations in theorizing an implementation science of integrated care. In response, we qualitatively explored the delivery of methadone after its introduction in Kenya to understand integration with HIV care. Semi-structured interviews with people using methadone (n = 30) were supplemented by stakeholder interviews (n = 2) and participant observation in one city. Thematic analysis was used, that also drew on Mol's logic of care as an analytical framework. Respondents described methadone clinic-based care embedded in community support systems. Daily observed clinic care was challenging for methadone and stigmatizing for HIV treatment. In response to these challenges, integration evolved and HIV care differentiated to other sites. The resulting care system was acceptable to respondents and allowed for choice over locations and approaches to HIV care. Using Mol's logic of care as an analytical framework, we explore what led to this differentiation in integrated care. We explore co-production and experimentation around HIV care that compares with more limited experimentation for methadone. This experimentation is bounded by available discourses and materials. The study supports continued integration of services whilst allowing for differentiation of these models to adapt to client preferences. Co-location of integrated services must prioritize clinic organization that prevents HIV status disclosure. Our analysis fosters a material perspective for theory of implementation science and integration of services that focuses attention on local experimentation shaped by context.

Integration of HIV and reproductive health services in public sector facilities: analysis of client flow data over time in Kenya

Introduction

Integration of HIV/AIDS with reproductive health (RH) services can increase the uptake and efficiency of services, but gaps in knowledge remain about the practice of integration, particularly how provision can be expanded and performance enhanced. We assessed the extent and nature of service integration in public sector facilities in four districts in Kenya.

Methods

Between 2009 and 2012, client flow assessments were conducted at six time points in 24 government facilities, purposively selected as intervention or comparison sites. A total of 25 539 visits were tracked: 15 270 in districts where 6 of 12 facilities received an intervention to strengthen HIV service integration with family planning (FP); and 10 266 visits in districts where half the facilities received an HIV-postnatal care intervention in 2009–2010. We tracked the proportion of all visits in which: (1) an HIV service (testing, counselling or treatment) was received together with an RH service (FP counselling or provision, antenatal care, or postnatal care); (2) the client received HIV counselling.

Results

Levels of integrated HIV-RH services and HIV counselling were generally low across facilities and time points. An initial boost in integration was observed in most intervention sites, driven by integration of HIV services with FP counselling and provision, and declined after the first follow-up. Integration at most sites was driven by temporary rises in HIV counselling. The most consistent combination of HIV services was with antenatal care; the least common was with postnatal care.

Conclusions

These client flow data demonstrated a short-term boost in integration, after an initial intervention with FP services providing an opportunity to expand integration. Integration was not sustained over time highlighting the need for ongoing support. There are multiple opportunities for integrating service delivery, particularly within antenatal, FP and HIV counselling services, but a need for sustained systems and health worker support over time.

Understanding the persistence of vertical (stand-alone) HIV clinics in the health system in Uganda: a qualitative synthesis of patient and provider perspectives

Background

Although there is mounting evidence and policy guidance urging the integration of HIV services into general health systems in countries with a high HIV burden, vertical (stand-alone) HIV clinics are still common in Uganda. We sought to describe the specific contexts underpinning the endurance of vertical HIV clinics in Uganda.

Methods

A qualitative research design was adopted. Semi-structured interviews were conducted with the heads of HIV clinics, clinicians and facility in-charges (n = 78), coupled with eight focus group discussions (64 participants) with patients from 16 health facilities purposively selected, from a nationally-representative sample of 195 health facilities across Uganda, because they run stand-alone HIV clinics. Data were analyzed by thematic approach as guided by the theory proposed by Shediac-Rizkallah & Bone (1998) which identifies; Intervention characteristics, organizational context, and broader environment factors as potentially influential on health programme sustainability.

Results

Intervention characteristics: Provider stigma was reported to have been widespread in the integrated care experience of participating health facilities which necessitated the establishment of stand-alone HIV clinics. HIV disease management was described as highly specialized which necessitated a dedicated workforce and vertical HIV infrastructure such as counselling rooms. Organizational context: Participating health facilities reported health-system capacity constraints in implementing integrated systems of care due to a shortage of ART-proficient personnel and physical space, a lack of laboratory capacity to concurrently conduct HIV and non-HIV tests and increased workloads associated with implementing integrated care. Broader environment factors: Escalating HIV client loads and external HIV funding architectures were perceived to have perpetuated verticalized HIV programming over the past decade.

Conclusion

Our study offers in-depth, contextualized insights into the factors contributing to the endurance of vertical HIV clinics in Uganda. Our analysis suggests that there is a complex interaction in supply-side constraints (shortage of ART-proficient personnel, increased workloads, laboratory capacity deficiencies) and demand-side factors (escalating demand for HIV services, psychosocial barriers to HIV care) as well as the specialized nature of HIV disease management which pose challenges to the integrated-health services agenda.

Impact of integration of sexual and reproductive health services on consultation duration times: results from the Integra Initiative

The lack of human resources is a key challenge in scaling up of HIV services in Africa's health care system. Integrating HIV services could potentially increase their effectiveness and optimize the use of limited resources and clinical staff time. We examined the impact of integration of provider initiated HIV counselling and testing (PITC) and family planning (FP counselling and FP provision) services on duration of consultation to assess the impact of PITC and FP integration on staff workload. This study was conducted in 24 health facilities in Kenya under the Integra Initiative, a non-randomized, pre/post intervention trial to evaluate the impact of integrated HIV and sexual and reproductive health services on health and service outcomes. We compared the time spent providing PITC-only services, FP-only services and integrated PITC/FP services. We used log-linear regression to assess the impact of plausible determinants on the duration of clients' consultation times. Median consultation duration times were highest for PITC-only services (30 min), followed by integrated services (10 min) and FP-only services (8 min). Times for PITC-only and FP-only services were 69.7% higher (95% Confidence Intervals (CIs) 35.8-112.0) and 43.9% lower (95% CIs -55.4 to - 29.6) than times spent on these services when delivered as an integrated service, respectively. The reduction in consultation times with integration suggests a potential reduction in workload. The higher consultation time for PITC-only could be because more pre- and post-counselling is provided at these stand-alone services. In integrated PITC/FP services, the duration of the visit fell below that required by HIV testing guidelines, and service mix between counselling and testing substantially changed. Integration of HIV with FP services may compromise the quality of services delivered and care must be taken to clearly specify and monitor appropriate consultation duration times and procedures during the process of integrating HIV and FP services.

Integrated care: learning between high-income, and low- and middle-income country health systems

Over the past decade, discussion of integrated care has become more widespread and prominent in both high- and low-income health care systems (LMICs). The trend reflects the mismatch between an increasing burden of chronic disease and local health care systems which are still largely focused on hospital-based treatment of individual clinical episodes and also the long-standing proliferation of vertical donor-funded disease-specific programmes in LMICs which have disrupted horizontal, or integrated, care. Integration is a challenging concept to define, in part because of its multiple dimensions and varied scope: from integrated clinical care for individual patients to broader systems integration-or linkage-involving a wide range of interconnected services (e.g. social services and health care). In this commentary, we compare integrated care in high- and lower-income countries. Although contexts may differ significantly between these settings, there are many common features of how integration has been understood and common challenges in its implementation. We discuss the different approaches to, scope of, and impacts of, integration including barriers and facilitators to the processes of implementation. With the burden of disease becoming more alike across settings, we consider what gains there could be from comparative learning between these settings which have constituted two separate strands of research until now.

The Current Status of Research on the Integration of Sexual and Reproductive Health and HIV Services

Integration of services for sexual and reproductive health (SRH) and HIV has been widely promoted globally in the belief that both clients and health providers benefit through improvements in quality, efficient use of resources, and lower costs, helping to maximize limited health resources and provide comprehensive client-centered care. This article builds on the growing body of research on integrated sexual SRH and HIV services. It brings together critical reviews on issues within the wider SRH and rights agenda and synthesizes recent research on integrated services, drawing on the Integra Initiative and other major research. Unintended pregnancy and HIV are intrinsically interrelated SRH issues, however broadening the constellation of services, scaling up, and mainstreaming integration continue to be challenging. Overcoming stigma, reducing gender-based violence, and meeting key populations' SRH needs are critical. Health systems research using SRH as the entry point for integrated services and interaction with communities and clients is needed to realize universal health coverage.

Impact of Integrated Services on HIV Testing: A Nonrandomized Trial among Kenyan Family Planning Clients

The impact of integrated reproductive health and HIV services on HIV testing and counseling (HTC) uptake was assessed among 882 Kenyan family planning clients using a nonrandomized cohort design within six intervention and six "comparison" facilities. The effect of integration on HTC goals (two tests over two years) was assessed using conditional logistic regression to test four "integration" exposures: a training and reorganization intervention; receipt of reproductive health and HIV services at recruitment; a functional measure of facility integration at recruitment; and a woman's cumulative exposure to functionally integrated care across different facilities over time. While recent receipt of HTC increased rapidly at intervention facilities, achievement of HTC goals was higher at comparison facilities. Only high cumulative exposure to integrated care over two years had a significant effect on HTC goals after adjustment (aOR 2.94, 95%CI 1.73-4.98), and programs should therefore make efforts to roll out integrated services to ensure repeated contact over time.
