Provider Initiated Testing and Counseling (PITC) for HIV in resource-limited clinical settings: important questions unanswered

Testing is the gateway to HIV care and support services, and efforts to broaden treatment must include a proactive and inclusive approach to testing. Provider Initiated Testing and Counseling (PITC) for HIV utilizes the opportunity afforded by the clinical encounter for the care provider to make a clinical recommendation that the patient have a voluntary HIV test. It is hoped that by broadening testing by such strategies as PITC more patients may be identified and linked to treatment and support. However, there exist multiple challenges and questions regarding the provision of routine HIV testing and counseling in clinical facilities. In order to support further PITC efforts and scale up of current testing programs, a research agenda that addresses the ethical, social and operational components of PITC programming in health facilities, is critically needed to further guide its expansion

Effectiveness of a combination strategy for linkage and retention in adult HIV care in Swaziland: The Link4Health cluster randomized trial

Background: Gaps in the HIV care continuum contribute to poor health outcomes and increase HIV transmission. A combination of interventions targeting multiple steps in the continuum is needed to achieve the full beneficial impact of HIV treatment. Methods and findings: Link4Health, a cluster-randomized controlled trial, evaluated the effectiveness of a combination intervention strategy (CIS) versus the standard of care (SOC) on the primary outcome of linkage to care within 1 month plus retention in care at 12 months after HIV-positive testing. Ten clusters of HIV clinics in Swaziland were randomized 1:1 to CIS versus SOC. The CIS included point-of-care CD4+ testing at the time of an HIV-positive test, accelerated antiretroviral therapy (ART) initiation for treatment-eligible participants, mobile phone appointment reminders, health educational packages, and noncash financial incentives. Secondary outcomes included each component of the primary outcome, mean time to linkage, assessment for ART eligibility, ART initiation and time to ART initiation, viral suppression defined as HIV-1 RNA < 1,000 copies/mL at 12 months after HIV testing among patients on ART ≥6 months, and loss to follow-up and death at 12 months after HIV testing. A total of 2,197 adults aged ≥18 years, newly tested HIV positive, were enrolled from 19 August 2013 to 21 November 2014 (1,096 CIS arm; 1,101 SOC arm) and followed for 12 months. The median participant age was 31 years (IQR 26–39), and 59% were women. In an intention-to-treat analysis, 64% (705/1,096) of participants at the CIS sites achieved the primary outcome versus 43% (477/1,101) at the SOC sites (adjusted relative risk [RR] 1.52, 95% CI 1.19–1.96, p = 0.002). Participants in the CIS arm versus the SOC arm had the following secondary outcomes: linkage to care regardless of retention at 12 months (RR 1.08, 95% CI 0.97–1.21, p = 0.13), mean time to linkage (2.5 days versus 7.5 days, p = 0.189), retention in care at 12 months regardless of time to linkage (RR 1.48, 95% CI 1.18–1.86, p = 0.002), assessment for ART eligibility (RR 1.20, 95% CI 1.07–1.34, p = 0.004), ART initiation (RR 1.16, 95% CI 0.96–1.40, p = 0.12), mean time to ART initiation from time of HIV testing (7 days versus 14 days, p < 0.001), viral suppression among those on ART for ≥6 months (RR 0.97, 95% CI 0.88–1.07, p = 0.55), loss to follow-up at 12 months after HIV testing (RR 0.56, 95% CI 0.40–0.79, p = 0.002), and death (N = 78) within 12 months of HIV testing (RR 0.80, 95% CI 0.46–1.35, p = 0.41). Limitations of this study include a small number of clusters and the inability to evaluate the incremental effectiveness of individual components of the combination strategy. Conclusions: A combination strategy inclusive of 5 evidence-based interventions aimed at multiple steps in the HIV care continuum was associated with significant increase in linkage to care plus 12-month retention. This strategy offers promise of enhanced outcomes for HIV-positive patients

Enrollment in HIV Care Two Years after HIV Diagnosis in the Kingdom of Swaziland: An Evaluation of a National Program of New Linkage Procedures

To improve early enrollment in HIV care, the Swaziland Ministry of Health implemented new linkage procedures for persons HIV diagnosed during the Soka Uncobe male circumcision campaign (SOKA, 2011–2012) and the Swaziland HIV Incidence Measurement Survey (SHIMS, 2011). Abstraction of clinical records and telephone interviews of a retrospective cohort of HIV-diagnosed SOKA and SHIMS clients were conducted in 2013–2014 to evaluate compliance with new linkage procedures and enrollment in HIV care at 92 facilities throughout Swaziland. Of 1,105 clients evaluated, within 3, 12, and 24 months of diagnosis, an estimated 14.0%, 24.3%, and 37.0% enrolled in HIV care, respectively, after adjusting for lost to follow-up and non-response. Kaplan-Meier functions indicated lower enrollment probability among clients 14–24 (P = 0.0001) and 25–29 (P = 0.001) years of age compared with clients > 35 years of age. At 69 facilities to which clients were referred for HIV care, compliance with new linkage procedures was low: referral forms were located for less than half (46.8%) of the clients, and few (9.6%) were recorded in the appointment register or called either before (0.3%) or after (4.9%) their appointment. Of over one thousand clients newly HIV diagnosed in Swaziland in 2011 and 2012, few received linkage services in accordance with national procedures and most had not enrolled in HIV care two years after their diagnosis. Our findings are a call to action to improve linkage services and early enrollment in HIV care in Swaziland

The Link4Health study to evaluate the effectiveness of a combination intervention strategy for linkage to and retention in HIV care in Swaziland: protocol for a cluster randomized trial

Background: Gaps in the HIV care continuum contribute to suboptimal individual health outcomes and increased risk of HIV transmission at the population level. Implementation science studies are needed to evaluate clinic-based interventions aimed at improving retention of patients across the continuum. Methods/design: Link4Health uses an unblended cluster site-randomized design to evaluate the effectiveness of a combination intervention strategy (CIS) as compared to standard of care on linkage to and retention in care among HIV-diagnosed adults in Swaziland. The CIS intervention targets a multiplicity of structural, behavioral, and biomedical barriers through five interventions: (1) point-of-care CD4 testing at time of HIV testing, (2) accelerated antiretroviral therapy (ART) initiation for eligible patients, (3) mobile phone appointment reminders, (4) care and prevention packages, and (5) non-cash financial incentives for linkage and retention. The unit of randomization is a network of HIV clinics inclusive of a secondary facility coupled with an affiliated primary facility. Ten study units were randomized based on implementing partner, geographic location, and historic volume of HIV patients. Target enrollment was 2200 individuals, each to be followed for 12 months. Eligibility criteria includes HIV-positive test, age >18 years, willing to receive HIV care at a clinic in the study unit and consent to study procedures. Exclusion criteria included previous HIV care in the past 6 months, planning to leave the community, and current pregnancy. The primary study outcome is linkage within 1 month and retention at 12 months after testing HIV positive. Secondary outcomes include viral load suppression at 12 months, time to ART eligibility and initiation, participant acceptability, and cost-effectiveness. The trial status is that study enrollment is complete and follow-up procedures are ongoing. Discussion: Link4Health evaluates a novel and pragmatic combination intervention strategy to improve linkage to and retention in care among adults with HIV in Swaziland. If the strategy is found to be effective, this study has the potential to inform HIV service delivery in resource-limited settings. Keywords: HIV Linkage Retentio

Transitioning to Country Ownership of HIV Programs in Rwanda

Agnes Binagwaho and colleagues describe how Rwanda achieved country ownership of its HIV programs

Determinants of Mortality and Loss to Follow-Up among Adults Enrolled in HIV Care Services in Rwanda

Antiretroviral therapy (ART) improves morbidity and mortality in patients with HIV, however high rates of loss to follow-up (LTF) and mortality have been documented in HIV care and treatment programs. We analyzed routinely-collected data on HIV-infected patients ≥15 years enrolled at 41 healthcare facilities in Rwanda from 2005 to 2010. LTF was defined as not attending clinic in the last 12 months for pre-ART patients and 6 months for ART patients. For the pre-ART period, sub-distribution hazards models were constructed to estimate LTF and death to account for competing risks. Kaplan-Meier (KM) and Cox proportional hazards models were used for patients on ART. Low rates of LTF and death were founds among pre-ART and ART patients in Rwanda but greater efforts are needed to retain patients in care prior to ART initiation, particularly among those who are healthy at enrollment

Comparing two service delivery models for the prevention of mother-to-child transmission (PMTCT) of HIV during transition from single-dose nevirapine to multi-drug antiretroviral regimens

<p>Abstract</p> <p>Background</p> <p>Mother-to-child transmission (MTCT) of HIV has been eliminated from the developed world with the introduction of multi-drug antiretroviral (md-ARV) regimens for the prevention of MTCT (PMTCT); but remains the major cause of HIV infection among sub-Saharan African children. This study compares two service delivery models of PMTCT interventions and documents the lessons learned and the challenges encountered during the transition from single-dose nevirapine (sd-nvp) to md-ARV regimens in a resource-limited setting.</p> <p>Methods</p> <p>Program data collected from 32 clinical sites was used to describe trends and compare the performance (uptake of HIV testing, CD4 screening and ARV regimens initiated during pregnancy) of sites providing PMTCT as a stand-alone service (<it>stand-alone site</it>) versus sites providing PMTCT as well as antiretroviral therapy (ART) (<it>full package site</it>). CD4 cell count screening, enrolment into ART services and the initiation of md-ARV regimens during pregnancy, including dual (zidovudine [AZT] +sd-nvp) prophylaxis and highly active antiretroviral therapy (HAART) were analysed.</p> <p>Results</p> <p>From July 2006 to December 2008, 1,622 pregnant women tested HIV positive (HIV+) during antenatal care (ANC). CD4 cell count screening during pregnancy increased from 60% to 70%, and the initiation of md-ARV regimens increased from 35.5% to 97% during this period. In 2008, women attending ANC at <it>full package </it>sites were 30% more likely to undergo CD4 cell count assessment during pregnancy than women attending <it>stand-alone </it>sites (relative risk (RR) = 1.3; 95% confidence interval (CI): 1.1-1.4). Enrolment of HIV+ pregnant women in ART services was almost twice as likely at <it>full package </it>sites than at <it>stand-alone </it>sites (RR = 1.9; 95% CI: 1.5-2.3). However, no significant differences were detected between the two models of care in providing md-ARV (RR = 0.9; 95% CI: 0.9-1.0).</p> <p>Conclusions</p> <p>All sites successfully transitioned from sd-nvp to md-ARV regimens for PMTCT. <it>Full package </it>sites offer the most efficient model for providing immunological assessment and enrolment into care and treatment of HIV+ pregnant women. Strengthening the capacity of <it>stand-alone </it>PMTCT sites to achieve the same objectives is paramount.</p

Implementation of Integrated Disease Surveillance and Response (IDSR) in Swaziland

Objective: To strengthen public health surveillance and monitor implementation of Integrated Disease Surveillance and Response in the Kingdom of Swaziland.Introduction: Swaziland adopted the Integrated Disease Surveillance and Response (IDSR) strategy in 2010 to strengthen Public Health Surveillance (PHS) that fulfills International Health Regulations (2005) and the Global Health Security Agenda (GHSA). This strategy allows the Ministry of Health (MoH), Epidemiology and Disease Control Unit (EDCU) to monitor, prevent and control priority diseases in the country. We used a health systems strengthening approach to pilot an intervention model for IDSR implementation at five hospitals in Swaziland over a pilot phase of three months.Methods: Our intervention included cross-country IDSR trainings, sensitizations and onsite trainings targeting national and regional health teams for over 250 health workers. The EDCU developed and disseminated standardized case definitions for health facilities (HFs) to detect, confirm and report priority conditions. Trained health care workers were tasked to cascade knowledge sharing and sensitization about IDSR with their HFs during in-service trainings. The facilities were to use IDSR standard case definition as guidelines for diagnosing and reporting cases; submit monthly reports on all priority conditions to Health Management Information System (HMIS) and intensify reporting through immediate disease notification system (IDNS) for all notifiable conditions. Indicators and monitoring tools for disease surveillance and response as recommended by the technical guidelines for IDSR in the African region were developed. The intervention was evaluated at five purposively selected high-volume referral hospitals (attending to ≥1500 to 15000 outpatient visits per month), which also have maternity services.Structured questionnaires in the form of a monitoring tool, checklists and observations were used to collect data. Quantitatively, monthly reports submitted by the five facilities to HMIS were reviewed and analyzed for completeness and timeliness. Clinic supervisors were identified from outpatient, inpatient, maternity and laboratory departments as key informants to explore successes and challenges of IDSR implementation. Additionally, IDSR officers visited health facilities and observed the registers and reporting forms used to report IDSR priority conditions and the availability of IDSR guidelines.Results: The five HFs submitted monthly reports from June to August 2017 with a calculated completeness of 80% in June 2017, 60% in July and 40% in August. Timeliness was calculated was at 20% in June, 20% in July and 40% in August. IDSR officers observed that all five HFs document cases of priority diseases in registers during consultations and use daily tally sheets. However, it was observed that diseases reported through the immediate diseases notification system were not all documented in the morbidity registers and vice versa. Health workers reported to be unaware about all diseases that require immediate notification to trigger investigation, hence some disease like perinatal deaths were never notified through the IDNS system during the period of evaluation. All five hospitals reported not utilizing the standard cases definitions provided to identify and report IDSR priority diseases.Conclusions: The proportion of completeness and timeliness from the five HFs during the evaluation period was low compared to WHO recommended standards of &gt;= 80% from all HFs. This therefore, poses challenges in monitoring and responding to the priority conditions as per IDSR standards and recommendations. All five hospitals reported not utilizing the standard cases definitions to identify and report IDSR priority diseases and this poses challenges in comparison of data across sites, monitoring priority diseases, conditions and events and also identifying the alert or epidemic thresholds. There is need to capacitate more health workers on IDSR for Swaziland to strengthen PHS and be able to prevent and control public health threats timely

Engagement in care among women and their infants lost to follow-up under Option B+ in eSwatini.

BackgroundUniversal antiretroviral treatment (ART) for pregnant women with HIV, Option B+, has been adopted widely for prevention of mother-to-child HIV transmission (PMTCT). Some evidence shows high loss to follow-up (LTF) under this model. However, gaps in data systems limit this evidence. We collected additional information for women and infants LTF from Option B+ in Eswatini to assess more accurate outcomes.MethodsLTF at 6-months postpartum was assessed using facility data. Additional data was gathered from: 1) the national ART database and paper records; 2) patient tracing; and 3) interviews and abstraction from patient-held records. Engagement in care was defined as any clinic visit within 91 days before or after 6-months postpartum or completion of a documented transfer; or, for those traced but not completing study interviews, visits at 6-months postpartum or later (for infants), or visits within 3-months of tracing (for women). Multivariable loglinear models were used to identify correlates of engagement.ResultsOne-hundred-ninety-four (44.7%) of 434 LTF women had outcomes ascertained, including 122 (62.9%) women engaged in care. Among 510 LTF infants, 265 (52.0%) had ascertained outcomes, including 143 (54.0%) engaged in care, 47 (17.7%) pregnancy losses, and 18 (6.8%) deaths. Seventy-two of 189 live infants (38.1%) with ascertained outcomes had a 6-week early infant diagnostic (EID) test. Among women with ascertained outcomes, gestational age of 20+ weeks (vs. fewer than 20 weeks, aRR 0.80; 95% CI 0.68-0.94) and age 25-29 years (vs. 15-24 years, aRR 0.81; 95% CI 0.67-0.97), were associated with lower engagement; initiating ART after first ANC visit was associated with higher engagement (vs. at first ANC visit, aRR 1.12; 95% CI 1.04-1.21). Among infants with ascertained outcomes, mother not initiating ART was associated with lower engagement (vs. ART at first ANC visit, aRR 0.71; 95% CI 0.54-0.91).ConclusionSubstantial numbers of women and infants classified as LTF under Option B+ were engaged in care, though a suboptimal level of 6-week EID testing was observed. These findings highlight a need to improve coverage of routine EID testing, and improve data systems to better capture PMTCT patient outcomes
