Integrating hypertension and HIV care in Namibia: A quality improvement collaborative approach.

BACKGROUND: Hypertension (HTN) is highly prevalent among people with HIV (PWH) in Namibia, but screening and treatment for HTN are not routinely offered as part of HIV care delivery. We report the implementation of a quality improvement collaborative (QIC) to accelerate integration of HTN and HIV care within public-sector health facilities in Namibia. METHODS: Twenty-four facilities participated in the QIC with the aim of increasing HTN screening and treatment among adult PWH (>15 years). HTN was defined according to national treatment guidelines (i.e., systolic blood pressure >140 and/or diastolic blood pressure >90 across three measurements and at least two occasions), and decisions regarding initiation of treatment were made by physicians only. Teams from participating hospitals used quality improvement methods, monthly measurement of performance indicators, and small-scale tests of change to implement contextually tailored interventions. Coaching of sites was performed on a monthly basis by clinical officers with expertise in QI and HIV, and sites were convened as part of learning sessions to facilitate diffusion of effective interventions. RESULTS: Between March 2017 and March 2018, hypertension screening occurred as part of 183,043 (86%) clinical encounters at participating facilities. Among 1,759 PWH newly diagnosed with HTN, 992 (56%) were initiated on first-line treatment. Rates of treatment initiation were higher in facilities with an on-site physician (61%) compared to those without one (51%). During the QIC, facility teams identified fourteen interventions to improve HTN screening and treatment. Among barriers to implementation, teams pointed to malfunctions of blood pressure machines and stock outs of antihypertensive medications as common challenges. CONCLUSIONS: Implementation of a QIC provided a structured approach for integrating HTN and HIV services across 24 high-volume facilities in Namibia. As rates of HTN treatment remained low despite ongoing facility-level changes, policy-level interventions-such as task sharing and supply chain strengthening-should be pursued to further improve delivery of HTN care among PWH beyond initial screening.

Improving Services for HIV-Exposed Infants in Zambia and Cameroon Using a Quality Improvement Collaborative Approach.

INTRODUCTION: Early infant diagnosis (EID) and rapid antiretroviral therapy (ART) initiation are lifesaving interventions for HIV-infected infants. In Cameroon and Zambia, EID coverage for HIV-exposed infants (HEIs) is suboptimal and the time to ART initiation for infants infected with HIV often exceeds national standards despite numerous policy and training initiatives. METHODS: ICAP at Columbia University supported the Cameroon and Zambia Ministries of Health (MOHs) and local partners to implement quality improvement collaboratives (QICs) to improve EID coverage and ART initiation at 17 health facilities (HFs) in Cameroon (March 2016 to June 2017) and 15 HFs in Zambia (March 2017 to June 2018). In each country, MOH led project design and site selection. MOH and ICAP provided quality improvement training and monthly supportive supervision, which enabled HF teams to conduct root cause analyses, design and implement contextually appropriate interventions, conduct rapid tests of change, analyze monthly progress, and convene at quarterly learning sessions to compare performance and share best practices. RESULTS: In Cameroon, EID testing coverage improved from 57% (113/197 HEIs tested) during the 5-month baseline period to 80% (165/207) in the 5-month endline period. In Zambia, EID testing coverage improved from 77% (4,773/6,197) during the 12-month baseline period to 89% (2,144/2,420) during the 3-month endline period. In a comparison of the same baseline and endline periods, the return of positive test results to caregivers improved from 18% (36/196 caregivers notified) to 86% (182/211) in Cameroon and from 44% (94/214) to 79% (44/56) in Zambia. ART initiation improved from 44% (94/214 HIV-infected infants) to 80% (45/56) in Zambia; the numbers of HIV-infected infants in Cameroon were too small to detect meaningful differences. CONCLUSIONS: QICs improved coverage of timely EID and ART initiation in both countries. In addition to building quality improvement capacity and improving outcomes, the QICs resulted in a "change package" of successful initiatives that were disseminated within each country.

A pragmatic approach to monitor and evaluate implementation and impact of differentiated ART delivery for global and national stakeholders.

INTRODUCTION: The World Health Organization's (WHO) recommendation of "Treat All" has accelerated the call for differentiated antiretroviral therapy (ART) delivery, a method of care that efficiently uses limited resources to increase access to HIV treatment. WHO has further recommended that stable individuals on ART receive refills every 3 to 6 months and attend clinical visits every 3 to 6 months. However, there is not yet consensus on how to ensure that the quality of services is maintained as countries strive to meet these standards. This commentary responds to this gap by defining a pragmatic approach to the monitoring and evaluation (M&E) of the scale up of differentiated ART delivery for global and national stakeholders. DISCUSSION: Programme managers need to demonstrate that the scale up of differentiated ART delivery is achieving the desired effectiveness and efficiency outcomes to justify continued support by national and global stakeholders. To achieve this goal, the two existing global WHO HIV treatment indicators of ART retention and viral suppression should be augmented with two broad aggregate measures. The addition of indicators measuring the frequency of (1) clinical and (2) refill visits by PLHIV per year will allow evaluation of the pace of scale up while monitoring its overall effect on the quality and efficiency of services. The combination of these four routinely collected aggregate indicators will also facilitate the comparison of outcomes among facilities, regions or countries implementing different models of ART delivery. Enhanced monitoring or additional assessments will be required to answer other critical questions on the process of implementation, acceptability, effectiveness and efficiency. CONCLUSIONS: These proposed outcomes are useful markers for the effectiveness and efficiency of the health system's attempts to deliver quality treatment to those who need it-and still reserve as much of the available resource pool as possible for other key elements of the HIV response.

Improving Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) Treatment Monitoring in South Africa: Evaluation of an Advanced TB/HIV Course for Healthcare Workers.

BACKGROUND: South Africa has dual epidemics of human immunodeficiency virus (HIV) and tuberculosis (TB). Nurse-focused training was combined with onsite mentoring for nurses to improve HIV and TB care. A pre-/postevaluation was conducted in 3 districts in South Africa to assess the effects of the course on clinical patient monitoring and integration of TB and HIV care. METHODS: Two cross-sectional, unmatched samples of patient charts at 76 primary healthcare facilities were collected retrospectively in 2014 to evaluate the impact of training on treatment monitoring. Proportions of HIV patients receiving a viral load test 6 months after initiating antiretroviral therapy (ART) and TB patients receiving end of intensive phase sputum testing were compared pre- and posttraining. Analysis of creatinine clearance testing and integration of TB and HIV care were also performed. RESULTS: Data were analyzed from 1074 pretraining and 1048 posttraining records among patients initiating ART and from 1063 pretraining and 1008 posttraining among patients initiating TB treatment. Documentation of a 6-month viral load test was 36.3%, and a TB test at end of intensive phase was 70.7%, and neither increased after training. Among patients with a viral load test, the percentage with viral load less than 50 copies/mL increased from 48.6% pretraining compared with 64.2% posttraining (P = .001). Integration of TB and HIV care such as isoniazid preventive therapy increased significantly. CONCLUSIONS: The primary outcome measures did not change after training. However, the evaluation documented many other improvements in TB and HIV care that may have been supported by the course.

A national evaluation using standardised patient actors to assess STI services in public sector clinical sentinel surveillance facilities in South Africa.

OBJECTIVES: Quality concerns in STI service delivery and missed opportunities for integration with HIV testing and prevention services in South Africa have been well documented. This national evaluation aimed to evaluate current utilisation and adherence to national STI guidelines, including partner notification and integration with HIV services, for diagnosis and management of STIs. METHODS: Facility surveys assessed infrastructure and resource availability, and standardised patient (SP) assessments evaluated quality of STI care in 50 public clinics in nine provinces in South Africa. The primary outcome was the proportion of SPs receiving essential STI care, defined as: offered an HIV test, condoms, partner notification counselling and correct syndromic treatment. Weighted proportions were generated, and SP findings were compared by gender using χ2 tests with Rao-Scott correction. RESULTS: More than 80% of facilities reported medications in stock, with the exceptions of oral cefixime (48.3%), oral erythromycin (75.1%) and paediatric syrups. Among 195 SP encounters, 18.7% (95% CI 10.7% to 30.5%) received all hypothesised essential STI services: offered HIV test (67.1%), offered condoms (31.4%), partner notification counselling (70.2%) and recommended syndromic treatment (60.7%). Men were more likely than women to be offered all services (25.1% vs 12.3%, p=0.023), recommended treatment (70.7% vs 50.9%, p=0.013) and partner notification counselling (79.9% vs 60.6%, p=0.020). Only 6.3% of providers discussed male circumcision with male SPs, and 26.3% discussed family planning with female SPs. CONCLUSIONS: This evaluation of STI services across South Africa found gaps in the availability of medications, adherence to STI guidelines, condom provision and prevention messaging. Limited integration with HIV services for this high-risk population was a missed opportunity. Quality of STI care should continue to be monitored, and interventions to improve quality should be prioritised as part of national strategic HIV and primary healthcare agendas.

Systems Mapping of Sexually Transmitted Infection Services at Three Clinical Sentinel Surveillance Sites in South Africa: Opportunities for Integrated Care.

Sexually transmitted infection (STI) service delivery in the context of integrated care and the South African HIV epidemic is complex. We aimed to document STI care and HIV testing processes in public health clinics in South Africa, revealing bottlenecks to patient flow and identifying opportunities for improvement. Clinic mapping, with semi-structured interviews and clinic observation, was conducted with facility representatives at three clinical sentinel surveillance sites. Facility surveys assessed patient volume and staffing. Identified challenges were associated with staffing allocations, and disruptions in patient flow resulted from poor clinic layout, inadequate lighting, and limited allocation of space for HIV testing and physical examination. Recommendations include staffing adjustments, reorganization of space to allow for designated service and waiting areas, sufficient supplies, and improved lighting. The facility reorganization component of South Africa's Ideal Clinic initiative provides a key opportunity for enacting many of these recommendations.

Three methods of delivering clinic-based training on syndromic management of sexually transmitted diseases in South Africa: a pilot study.

INTRODUCTION: The South African National Department of Health sought to improve syndromic management of sexually transmitted infections (STIs). Continuing medical education on STIs was delivered at primary healthcare (PHC) clinics using one of three training methods: (1) lecture, (2) computer and (3) paper-based. Clinics with training were compared with control clinics. METHODS: Ten PHC clinics were randomly assigned to control and 10 to each training method arm. Clinicians participated in on-site training on six modules; two per week for three weeks. Each clinic was visited by three or four unannounced standardised patient (SP) actors pre-training and post-training. Male SPs reported symptoms of male urethritis syndrome and female SPs reported symptoms of vaginal discharge syndrome. Quality of healthcare was measured by whether or not clinicians completed five tasks: HIV test, genital exam, correct medications, condoms and partner notification. RESULTS: An average of 31% of clinicians from each PHC attended each module. Quality of STI care was low. Pre-training (n=128) clinicians completed an average of 1.63 tasks. Post-training (n=114) they completed 1.73. There was no change in the number of STI tasks completed in the control arm and an 11% increase overall in the training arms relative to the control (ratio of relative risk (RRR)=1.11, 95% CI 0.67 to 1.84). Across training arms, there was a 26% increase (RRR=1.26, 95% CI 0.77 to 2.06) associated with lecture, 17% increase (RRR=1.17, 95% CI 0.59 to 2.28) with paper-based and 13% decrease (RRR=0.87, 95% CI 0.40 to 1.90) with computer arm relative to the control. CONCLUSIONS: Future interventions should address increasing training attendance and computer-based training effectiveness. TRIAL REGISTRATION NUMBER: AEARCTR-0000668.
