Health Impact and Cost-Effectiveness of HIV Testing, Linkage, and Early Antiretroviral Treatment in the Botswana Combination Prevention Project.

BACKGROUND: The Botswana Combination Prevention Project tested the impact of combination prevention (CP) on HIV incidence in a community-randomized trial. Each trial arm had ∼55,000 people, 26% HIV prevalence, and 72% baseline ART coverage. Results showed intensive testing and linkage campaigns, expanded antiretroviral treatment (ART), and voluntary male medical circumcision referrals increased coverage and decreased incidence over ∼29 months of follow-up. We projected lifetime clinical impact and cost-effectiveness of CP in this population. SETTING: Rural and periurban communities in Botswana. METHODS: We used the Cost-Effectiveness of Preventing AIDS Complications model to estimate lifetime health impact and cost of (1) earlier ART initiation and (2) averting an HIV infection, which we applied to incremental ART initiations and averted infections calculated from trial data. We determined the incremental cost-effectiveness ratio [US$/quality-adjusted life-years (QALY)] for CP vs. standard of care. RESULTS: In CP, 1418 additional people with HIV initiated ART and an additional 304 infections were averted. For each additional person started on ART, life expectancy increased 0.90 QALYs and care costs increased by $869. For each infection averted, life expectancy increased 2.43 QALYs with $9200 in care costs saved. With CP, an additional $1.7 million were spent on prevention and $1.2 million on earlier treatment. These costs were mostly offset by decreased care costs from averted infections, resulting in an incremental cost-effectiveness ratio of $79 per QALY. CONCLUSIONS: Enhanced HIV testing, linkage, and early ART initiation improve life expectancy, reduce transmission, and can be cost-effective or cost-saving in settings like Botswana.

Promoting Health Equity Through Purposeful Design and Professionalization of Resident Global Health Electives in Obstetrics and Gynecology.

OBJECTIVE: To design an Obstetrics and Gynecology (OBGYN) residency elective in global health that meets ACGME standards and simultaneously promotes health equity. DESIGN: A 4-week elective was established for US residents in a high-volume African district hospital that served as a site for OBGYN rotations for the national internship training program. Clear clinical, operative, and teaching requirements were delineated for US OBGYN residents. Resident formal didactic outputs were incorporated into the intern OBGYN curriculum. The program was evaluated through assessment of resident experience and contribution to local training, as well as assessment of intern competency in OBGYN. SETTING: Scottish Livingstone Hospital, a public district hospital in Molepolole, Botswana. PARTICIPANTS: Second- to fourth-year OBGYN residents from US training programs, working with Batswana medical interns under on-site faculty supervision. RESULTS: From May 2016 to June 2018, 18 residents from 9 US OBGYN residency programs participated in the elective. Under supervision, US residents performed 116 major and 77 minor gynecologic surgeries, and teach-assisted Batswana interns and medical officers in 76 cesarean deliveries. Residents led or contributed significantly to 25 didactic education sessions as part of the formal intern OBGYN curriculum. During this period, 24 Batswana interns rotated through the hospital's department of OBGYN, and all 24 trainees met required OBGYN competencies prior to completing their internship. CONCLUSIONS: Matching US resident demand for global health experiences to equitable global health programming while maintaining ACGME training guidelines poses a challenge to OBGYN residency training programs. This elective provides a model OBGYN global health elective that addresses host-identified needs, broadens residents' skills, and meets standards for postgraduate OBGYN training. Purposeful global health electives for US residents embedded in longitudinal programs provide an opportunity for residents to contribute to broader global health efforts that promote health equity.

An augmented SMS intervention to improve access to antenatal CD4 testing and ART initiation in HIV-infected pregnant women: a cluster randomized trial.

BACKGROUND: Less than one-third of HIV-infected pregnant women eligible for combination antiretroviral therapy (ART) globally initiate treatment prior to delivery, with lack of access to timely CD4 results being a principal barrier. We evaluated the effectiveness of an SMS-based intervention to improve access to timely antenatal ART. METHODS: We conducted a stepped-wedge cluster randomized trial of a low-cost programmatic intervention in 20 antenatal clinics in Gaborone, Botswana. From July 2011-April 2012, 2 clinics were randomly selected every 4 weeks to receive an ongoing clinic-based educational intervention to improve CD4 collection and to receive CD4 results via an automated SMS platform with active patient tracing. CD4 testing before 26 weeks gestation and ART initiation before 30 weeks gestation were assessed. RESULTS: Three-hundred-sixty-six ART-naïve women were included, 189 registering for antenatal care under Intervention and 177 under Usual Care periods. Of CD4-eligible women, 100 (59.2%) women under Intervention and 79 (50.6%) women under Usual Care completed CD4 phlebotomy before 26 weeks gestation, adjusted odds ratio (aOR, adjusted for time that a clinic initiated Intervention) 0.87 (95% confidence interval [CI]0.47-1.63, P = 0.67). The SMS-based platform reduced time to clinic receipt of CD4 test result from median of 16 to 6 days (P<0.001), was appreciated by clinic staff, and was associated with reduced operational cost. However, rates of ART initiation remained low, with 56 (36.4%) women registering under Intervention versus 37 (24.2%) women under Usual Care initiating ART prior to 30 weeks gestation, aOR 1.06 (95%CI 0.53-2.13, P = 0.87). CONCLUSIONS: The augmented SMS-based intervention delivered CD4 results more rapidly and efficiently, and this type of SMS-based results delivery platform may be useful for a variety of tests and settings. However, the intervention did not appear to improve access to timely antenatal CD4 testing or ART initiation, as obstacles other than CD4 impeded ART initiation during pregnancy.
