The period of transition from pediatric to adult care has been associated with poor health outcomes among 10–19 year old adolescents living with HIV (ALHIV). This has prompted a focus on the quality of transition services, especially in high ALHIV-burden countries. Due to lack of guidelines, there are no healthcare transition standards for Nigeria’s estimated 240,000 ALHIV. We conducted a nationwide survey to characterize routine transition procedures for Nigerian ALHIV.

Materials and methods

This cross-sectional survey was conducted at public healthcare facilities supported by five local HIV service implementing partners. Comprehensive HIV treatment facilities with ≥1 year of HIV service provision and ≥20 ALHIVs enrolled were selected. A structured questionnaire assessed availability of treatment, care and transition services for ALHIV. Transition was defined as a preparatory process catering to the medical, psychosocial, and educational needs of adolescents moving from pediatric to adult care. Comprehensive transition services were defined by 6 core elements: policy, tracking and monitoring, readiness evaluation, planning, transfer of care, and follow-up.


All 152 eligible facilities were surveyed and comprised 106 (69.7%) secondary and 46 (30.3%) tertiary centers at which 17,662 ALHIV were enrolled. The majority (73, 48.3%) of the 151 facilities responding to the “clinic type” question were family-centered and saw all clients together regardless of age. Only 42 (27.8%) facilities had an adolescent-specific HIV clinic; 53 (35.1%) had separate pediatric/adolescent and adult HIV clinics, of which 39 (73.6%) reported having a transfer/transition policy. Only 6 (15.4%) of these 39 facilities reported having a written protocol. There was a bimodal peak at 15 and 18 years for age of ALHIV transfer to adult care. No surveyed facility met the study definition for comprehensive transition services.


Facilities surveyed were more likely to have non-specialized HIV treatment services and had loosely-defined, abrupt transfer versus transition practices, which lacked the core transition elements. Evidence-based standards of transitional care tailored to non-specialized HIV treatment programs need to be established to optimize transition outcomes among ALHIV in Nigeria and in similar settings.


Despite a 30% decrease in the number of all AIDS-related deaths between 2005 and 2012, mortality among adolescents living with HIV (ALHIV) increased by 50% within that same period [1,2]. Nearly 92% of these deaths occurred in sub-Saharan Africa [3], where AIDS is the leading cause of mortality among adolescents [4,5]. This has been attributed in part to high loss to follow-up (LTFU) rates that appear to spike even higher around the period of transition from pediatric to adult care [6,7]. Multiple studies on HIV and other chronic illnesses among adolescents have demonstrated high drop-out rates around the transition period, leading to poor retention in care and increased morbidity and mortality [6,811].

Healthcare transition is defined as “the purposeful, planned movement of adolescents and young adults with chronic physical and medical conditions from child-centered to adult-oriented health care systems” [10]. Adolescent transition practices vary across different settings and disease conditions. Studies on transition models have to date been largely conducted in resource-rich North American and European settings among adolescents and young people with various chronic health conditions including diabetes, cystic fibrosis, and organ transplantation [1214]. The few available studies evaluating transition models among adolescents living with HIV (ALHIV) were also conducted largely in North America and Europe, and engaged patients between 15 and 23 years of age [1517]. Education programs, transition coordinators and interdisciplinary teams, transition readiness evaluation, visits to both pediatric and adult clinics during transition, and enhanced follow-up were identified by these studies as interventions and strategies that impacted positively on transition outcomes [16,17].

There is a lack of data on prevailing transition practices and limited evidence for effective transition strategies for ALHIV in Africa [17]. A recent review on the needs and challenges of transitioning ALHIV in sub-Saharan Africa noted that most African countries had no specific national guidelines on when and how to transition ALHIV to adult care [18]. Nigerian ALHIV account for approximately 15% of the 1.75 million ALHIV in sub-Saharan Africa, second only to South Africa [19,20]. The large number of Nigerian ALHIV require comprehensive transition services to usher them into adult care with minimized drop-out, morbidity and mortality. It is concerning to note that among the 5 countries with the highest burdens of ALHIV (South Africa, Nigeria, Kenya, Tanzania and Uganda), only Nigeria continues to experience increases in mortality among both younger and older adolescents [21]. Nigeria’s Federal Ministry of Health has developed multiple policies regarding adolescent and young people’s health, including HIV care and treatment [2224]. However, these documents and the current national HIV guidelines [25] provide little guidance on transitioning from pediatric to adult HIV care. Due to the lack of transition guidelines in Nigeria, this process is likely to vary widely across healthcare facilities.

The purpose of this study was to characterize current practices and services available for transitioning ALHIV from pediatric to adult HIV care across Nigeria.


Study design and setting

This cross-sectional survey was a collaboration between five Nigerian non-governmental organizations (NGOs) that serve as in-country implementing partners for the United States’ Presidency Emergency Plan for AIDS Relief (PEPFAR): APIN Public Health Initiatives; Center for Clinical Care and Clinical Research, Nigeria; Center for Integrated Health Programs, FHI 360, and the Institute of Human Virology Nigeria. Within our study setting in Nigeria, between 75 and 82% of annual HIV service financing has been supported by external donors to date, the two largest being PEPFAR and the Global Fund [26]. However, PEPFAR support has singularly encompassed up to 65% of annual expenditures for Nigeria’s HIV program [2628].

All five NGOs participating in this study are institutional members of the Nigeria Implementation Science Alliance, an umbrella organization established to facilitate the generation and application of impactful evidence towards health improvements in Nigeria [24]. With PEPFAR funding, these five NGOs provide support for HIV prevention, treatment and care at nearly 1,000 comprehensive HIV treatment centers across 30 of the 37 states and territories in Nigeria. At the time of the survey, these HIV treatment centers catered to over 24,000 Nigerian ALHIV aged 10 to 19 years. The survey was conducted as a program evaluation as well as pre-study site assessments to inform the implementation of the Adolescent Coordinated Transition (ACT) study, a National Institutes of Health-funded study on adolescent HIV transitioning in Nigeria [29].

Study site selection criteria

PEPFAR-supported sites in Nigeria receive HIV-related service funding and technical support from PEPFAR-funded NGOs known as implementing partners. Operations and commodities for services including HIV testing, early infant diagnosis, CD4/viral load monitoring, anti-retroviral drugs and drugs for HIV co-infections/opportunistic infections, programmatic data collection, healthcare worker capacity-building and program quality improvements are financed and/or facilitated by the implementing partner with PEPFAR funds. Additionally, implementing partners train and provide supportive supervision and mentoring to government-employed healthcare workers to provide competent prevention, care and treatment for clients per existing national guidelines. At each facility, one healthcare worker functions as the focal person for each pediatric/adolescent, adult, and prevention of mother-to-child transmission of HIV (PMTCT) program. It should be noted that depending on the level of care (primary, secondary or tertiary) and human resources for health available, facilities may provide services for only one programmatic area-for example PMTCT services only, or all of them.

Sites were selected from the network of facilities supported by the five participating implementing partners, based on the following criteria:

  • PEPFAR-supported public healthcare facility
  • Provision of comprehensive HIV services (HIV prevention, care and treatment services to adults, adolescents, children and pregnant women) for ≥1 year
  • ≥ 20 ALHIV aged 10 to 19 years enrolled in care as of July 31, 2016.

Primary healthcare facilities were excluded as these sites were not mandated to provide pediatric HIV treatment services per national guidelines [30]; however these sites may have older adolescents enrolled in adult care.

The selection strategy focused on facilities experienced in HIV care that had received sufficient capacity-building and mentoring to establish all components of HIV service delivery according to national HIV guidelines. Furthermore, the requirement of at least 20 ALHIV enrolled allowed for surveying of sites that had a consistently sizeable cohort of adolescents with which to maintain a sustained pediatric/adolescent HIV program. PEPFAR-only sites were selected because PEPFAR funding was common to all the participating NGOs; not all participating NGOs received Global Fund support. Additionally, the geographical scope of PEPFAR support provided by these five implementing partners covered all six geopolitical zones, ensuring national representation towards generalizable findings.

Ethical considerations

This survey was conducted as pre-study site assessments and a program evaluation that did not involve patient contact, the viewing of medical records nor the collection of names, addresses or any other identifying patient data from adolescents enrolled at the study facilities. The leadership for each NGO as well as focal persons at each surveyed site were briefed on the study procedures and nature of data to be collected before study initiation. The lead NGO for this study, the Institute of Human Virology Nigeria, obtained prior approval from the Nigerian National Health Research Ethics Committee for the analysis of HIV programmatic data for program evaluation. Separate ethical approval was obtained for the prospective ACT study.

Study tool and data collection

For this study, we use the term ‘transfer’ to refer to an often abrupt and passive change in healthcare provider and/or clinic for adolescents moving from pediatric to adult care with little or no preparation or follow up [31]. We use ‘transition’ to refer to an active process that prepares and caters to the medical, psychosocial, and educational needs of adolescents as they get ready to move from pediatric to adult-oriented care [31].

Both study and HIV program staff developed the structured survey questionnaire [S1 File], which was based on the Got Transition Center’s 6 core elements of healthcare transition of youth into adult care [32], as follows:

  • A Transition Policy: Developing a transition policy/statement with input from adolescents and families that describes the practice’s approach to transition.
  • Transition Tracking and Monitoring: Establish criteria and process for identifying transitioning youth
  • Assessment of Transition Readiness: Conduct regular transition readiness assessments
  • Transition Planning: Plan with youth/parent/caregiver for optimal timing of transfer
  • Transfer of Care: Confirm date of first adult provider appointment; Transfer young adult when his/her condition is stable, complete transfer package, including medical summary.
  • Verification of Transfer Completion: Contact young adult and parent/caregiver a few months after last pediatric visit to confirm transfer of responsibilities to adult practice; communicate with adult practice confirming completion of transfer.

The Got Transition Center’s elements for healthcare transitioning are in line with transitioning guidelines endorsed by pediatric, family practice, and internal medicine societies in the United States[32], as well as being consistent with the World Health Organization’s recommendations for transitioning of ALHIV [33].

The survey questionnaire was ultimately organized into five sections:

Section A: Site profile: brief description of the facility and aggregate ALHIV data.

Section B: Clinic services: information on services provided to pediatric and adolescent clients.

Section C: Adolescent care services: described services provided in the adolescent clinic, if any existed at the surveyed facility.

Section D: Adolescent support group services was used to ascertain support group activities available for ALHIV.

Section E: Transfer of adolescents from pediatric to adult clinic: described routine practices of transfer/transition from the pediatric to adult clinic.

The survey questionnaire was administered to focal persons for the adult, adolescent and/or pediatric HIV programs who provided relevant service availability/delivery data regarding the study sites. Where these focal persons were not appointed or not available, other facility staff with relevant knowledge of pediatric and adolescent HIV care at their facility were interviewed. The questionnaire was administered in person by trained study staff from each of the five implementing partners. Phone interviews were conducted for facilities where respondents were physically unavailable but offered to provide information. Data on ALHIV enrollments were abstracted from routine programmatic reporting tools that collected only aggregated data.

All data was collected manually on hard copy questionnaire forms and entered by study coordinators from the 5 implementing partners into a Microsoft Access database. Second and third-level validations were conducted by the central study team, using the completed hard copies against entries in the electronic Microsoft Access database. Descriptive statistics were applied to the data; in addition, a two-sample t-test was conducted to compare the mean age of transfer between facilities that had an ALHIV clinic and those that did not. Data were analyzed using SPSS version 21 [34]. The survey was initiated and completed in September 2016.


All facilities that met the predefined selection criteria were surveyed. A total of 152 comprehensive healthcare facilities were included, and had a total of 17,662 ALHIV enrolled comprising 7,814 young ALHIV 10–14 years old and 9,848 older ALHIV 15–19 years old. ALHIV enrollment ranged between 20 and 348 per surveyed facility. Surveyed facilities spanned a 30-state network of sites supported by the five implementing partners in all six geopolitical zones of Nigeria. Of the 152 facilities surveyed, 106 (69.7%) were secondary-level and 46 (30.3%) were tertiary healthcare centers. Most (67.8%) of the 180 survey respondents were doctors, followed by an equal proportion of nurses (16.1%) and other healthcare worker cadres (16.1%, comprising largely of monitoring and evaluation officers and adherence counsellors). Nearly three-quarters (72.8%) of all respondents were serving as pediatric, adult or general ART focal persons at their facilities.

Out of a total of 151 facilities (one missing response), 73 (48.3%) saw all HIV-positive clients together regardless of age in family-centered clinics; 42 (27.8%) saw ALHIV in separate adolescent clinics, and 36 facilities (23.8%) saw younger and older adolescent clients in pediatric and adult clinics respectively. Approximately 88% of facilities (133/151, with one missing response) had been providing adult HIV services for six years or more, while 85% (128/151) had been providing pediatric HIV services for six years and more. An additional 16/151 (10.6%) and 19/151 (12.6%) facilities reported delivering adult and pediatric HIV services for 4–6 years respectively. Only two facilities reported providing adult or pediatric HIV services for 1–3 years, and another two reported providing pediatric services for less than one year.

Fifty-three (34.9%) of 151 facilities had separate pediatric/adolescent and adult HIV clinics. Thirty-nine (73.6%) of these 53 facilities reported having an established practice for transferring/transitioning adolescents from pediatric to adult care; however, only six of these had a written protocol (Table 1). All 39 facilities that reported having a routine practice for transferring/transitioning ALHIV used age as a transfer criterion. Only 37/152 (24.3%) facilities had established ALHIV support groups (Table 1).

Table 1. Services available and routine practices for transferring/transitioning alhiv from pediatric to adult care.

A total of 85 (55.9%) of the 152 surveyed facilities reported having a specific age for ALHIV transfer. Age of ALHIV transfer ranged from 12 to 25 years; however, we observed a bimodal peak in transfer age at 15 years for 40/85 facilities (47.1%) and 18 years for 23/85 facilities (27.1%) (Fig 1). Additionally, among the 85 facilities that responded, the mean age of transfer at 42 facilities that had a dedicated ALHIV clinic was significantly higher (17.4 years) than the 43 facilities that did not have an ALHIV clinic (15.9 years), p = 0.006.

Plotted lines on bars indicate proportion of facilities reporting corresponding age as their routine age of transfer.

Overall, 72/148 (48.6%) facilities indicated having routine practices for providers to facilitate HIV status disclosure to ALHIV. The median age at which the disclosure process was initiated was 10 years (IQR 8 to 15 years); the minimum-maximum age range was 5 to 18 years. Only 11/72 (15.3%) facilities reported having a written disclosure protocol.

Cadre and numbers of healthcare workers delivering pediatric and adult HIV services at surveyed facilities are displayed in Table 2. Secondary facilities had a noticeable absence of doctors with regards to pediatric HIV clinics. Overall, psychosocial staff numbers were relatively sparse across all clinics and facilities.

Among facilities surveyed across Nigeria, our study found routine practices bearing similarities to the major models of adolescent transition/transfer described in the literature [29]: transition between distinct pediatric and adult HIV providers and services; transition between the same providers/clinic with or without a family-centered approach, and transition utilizing adolescent transition clinics.

Approximately 35% of surveyed facilities, mostly tertiary-level, operated separate pediatric and adult HIV clinics. Even though nearly 75% of these mostly specialized facilities reported having an established ALHIV transition policy, none of them, and indeed none of the 152 surveyed facilities, fulfilled all of the Got Transition Center’s six core elements of healthcare transitioning for youth [32]. Abrupt transfer focusing largely on age- rather than a transition process- was the common practice among 39 surveyed facilities that reported having an established “transition” policy. The paucity of written protocols highlights the lack of well-established, evidence-informed guidelines for adoption and use at the facility level. Our findings are consistent with what prevails in many other sub-Saharan African countries [3538] explained in part by the lack of clinic infrastructure and adolescent health-trained staff [35]. However, transition has been noted to be a somewhat newer concept particularly in Nigeria’s sub-region of West and Central Africa, in part due to the predominance of family-centered care models in this region’s public health sector [35].

Of equal importance are transition practices in non-specialized settings, which were the prevailing circumstances at two-thirds of all surveyed sites. This is not surprising, given the predominance of non-specialized care in sub-Saharan Africa [33]. Age was the most common criterion for transfer across surveyed sites, including at non-specialized facilities which did not have separate pediatric and adult clinics. Reported transfers at these sites are likely due to external transfers to other facilities, or more so, “programmatic transfers”- where adolescents reaching the reporting age for adults in the HIV program (15 years and above) are re-categorized as adults for reporting purposes. This would explain the observed peak at 15 years for transfer; the second peak at age 18 years is most likely due to the attainment of legal age and/or delayed ALHIV transfers to adult clinics at facilities with established adolescent HIV clinics. While chronological age appears to be a strong transfer criterion, it is also critical to consider readiness by age of maturity of the patient, which may vary depending on level of social support, education, and learning capabilities[35,36].

Whatever the case, ALHIV transition practice in non-specialized, more family-centered settings deserve more attention given their predominance, as demonstrated by our study. Adolescent HIV clinics were in existence at less than a third of surveyed sites, and facilities with these clinics are often specialized. Although one study [39] showed relatively higher retention in care among adolescents in a non-specialized and family-centered care program, outcome results of different care models for transitioned/transferred adolescents in Africa have been few and mixed [4042]. Clearly, transitioning ALHIVs and the challenges they face are heterogeneous, and more studies are needed to further describe their characteristics and needs. However, this also raises the challenge of establishing differentiated care models in non-specialized settings, which is a particular challenge in West and Central Africa [38]. The Got Transition Center has additional guidelines for transitioning adolescents to an adult approach to healthcare within non-specialized settings where pediatric and adult care clinics are not physically separate [32]. This requires the family/general health provider to change their approach to care for the transitioning adolescent, which includes gradually integrating the latter into adult model of care. This approach to transition appears much better-suited to the family-centered care model that exists across much of Nigeria and in similar settings.

Pregnancy and marriage were also reported as criteria for transitioning adolescents at some of our surveyed facilities. While these events may appear to be natural indicators for adulthood and therefore adult care, some pregnant and married ALHIV may be still too young or not mature enough to be transferred to adult care. This may be especially true in some parts of Nigeria where early marriage is not uncommon, especially among adolescent girls. The combination of teenage pregnancy (within or outside the context of marriage) and HIV infection may require more support and a prolonged transition period before transfer to adult care. These adolescents may be at higher risk of LTFU and may subsequently develop poor clinical, physical and psychosocial outcomes if transition is not successful [6]. Additionally, PMTCT outcomes are consistently reported to be worse for adolescent girls compared to older women and as such this population needs special attention [43].

Few surveyed facilities used immunologic and virologic criteria for transfer. Studies have shown that poor pre-transition outcomes are predictive of poor post-transition outcomes the utility of immunologic/virologic data in these contexts lie in the pre-transition identification of ALHIVs at high risk of poor outcomes in order to optimize their post-transition outcomes [40,44,45]. The clinical discretion of healthcare providers should be considered in the determination of transfer readiness. Providers may determine an ALHIV with, or at risk of immunologic/virologic failure not ready for transfer even when other milestones (including age) have been reached.

Support groups and routine disclosure procedures were reported as available at approximately a quarter and nearly half, respectively, of surveyed facilities. Psychosocial support and knowledge of HIV status have been reported to facilitate better treatment outcomes in some studies among ALHIV [46,47]. In a recent study, Nigerian ALHIV reported “seeking social support” as a coping strategy for major psychological stress related to living with HIV [48]. PEPFAR supports this strategy, and recommended peer psychosocial support for pediatric/adolescent adherence and retention in its Nigeria country operational plan that was in effect during study implementation [49] and thereafter [50]. It would be important to formalize the disclosure process and expand access to group or individual psychosocial support for ALHIV within both specialized and family-centered care models in Nigeria. The availability of trained and competent psychosocial support staff (including peers) to augment clinical service delivery to ALHIV cannot be overstated. Our findings show a paucity of these staff at surveyed sites.

A potential limitation to the generalizability of these findings is that only PEPFAR-supported health facilities were included in the survey. Health facilities not supported by PEPFAR may not have access to the same resources, and care in those facilities might differ from those surveyed in our study. However the cross-zonal, nationwide scope of our survey and the majority representation of PEPFAR country support for HIV services still lend to the study’s generalizability. Another limitation is that of the comprehensiveness of facility profile data: while we collected information on healthcare worker cadres in pediatric/adult/general HIV clinics, we did not collect detailed information on the number of specialties and entire scope of clinical services available at surveyed facilities. This could have helped characterize the facilities better in relation to transfer/transition practices.


This situational analysis of ALHIV healthcare transition/transfer practices across Nigeria demonstrates that routine practices vary widely, and current transition procedures are not comprehensive. Implementation research is sorely needed to identify ALHIV transfer/transition models and strategies that are most feasible and effective for Nigeria’s largely non-specialized, family-centered HIV care settings. Approaches to determining transition readiness should not be limited to chronologic age; immunologic/virologic and mental health status should also be considered. Nigeria and similar high HIV burden, resource-constrained countries require evidence-informed public health approaches to consolidate gains made in HIV treatment among children by ensuring optimal transition/transfer outcomes for adolescents.
