Abstract
Tuberculosis is the most common cause of death in people who are HIV-infected. Research has shown that when TB and HIV treatment and services are offered together there is a decrease in deaths for patients who have both these diseases. However, health care facilities in poor and developing countries struggle to efficiently provide both TB and HIV services to patients. We are testing whether an intervention for clinic staff, called ‘Quality Improvement’, will assist the staff to work in a more planned and structured manner to incorporate both TB and HIV services in their clinic and provide excellent quality of services. Our study will select 40 clinics from 2 rural districts in KwaZulu, South Africa and at random assign 20 clinics to receive the Quality Improvement intervention and 20 clinics to receive the standard support for delivering both TB and HIV services. We anticipate that clinics receiving the Quality Improvement intervention will have lower numbers of patient deaths from TB and HIV than those clinics receiving the standard support. Our study will inform how we can make combined TB and HIV services more manageable for clinics in poor and developing countries and so reduce deaths in TB and HIV patients.
Technical Summary
Tuberculosis (TB) and HIV prevalence is highest in sub-Saharan Africa, a region with limited health budgets, infrastructure, human resources, and suboptimal TB infection control practices. Persistently high rates of mortality and morbidity associated with HIV and TB continues to devastate families and overwhelm heath systems in South Africa. A large and compelling clinical evidence base suggests that integrating HIV and TB services improves survival in co-infected patients and presents a more effective & efficient use of limited health resources. Global policy makers have been responsive in translating research findings into TB HIV integration policy and recommendations, however there is a growing concern that the gains made in the field of TB HIV research will not be realized if not effectively translated into practice at the point-of-care. Implementing the full integrated TB HIV service ‘package’ at a health care facility level is not simple as very little is known about the best ‘scale up’ model for integrated TB HIV service delivery. This study is a cluster randomized controlled trial, which evaluates the effectiveness of implementing a quality improvement model to integrate TB HIV service delivery in primary health care clinics. The study will be conducted in 2 rural districts in KwaZulu-Natal, South Africa, namely the Ugu & uThungulu districts. Our hypothesis is that survival rates in TB and HIV infected patients accessing services in clinics using Quality Improvement methods to deliver comprehensive and reliable processes in implementing integrated TB HIV care, will be better than in patients accessing services in clinics provided with standard support for implementing TB HIV clinical guidelines. The anticipated eventual product arising from this study is a set of principles/model on how integrated TB HIV services maybe embedded in primary health care clinics in resource constrained settings. This study has the potential to elucidate which resources (inputs), processes (steps) and outputs lead to fully integrated TB HIV services hence impacting on improving the survival of co-infected patients.

Description | Research in context Evidence before this study: Initially in 2013, Medline via PubMed was searched for articles published between 2003 and 2013 reporting on search terms: "epidemiology of HIV-TB co-infection"; "integrated HIV-TB care, TB case finding among people living with Human Immunodeficiency Virus HIV)/acquired immunodeficiency syndrome (AIDS) (PLWHA)"; "isoniazid preventive therapy (IPT) and antiretroviral therapy (ART) uptake"; and "strategies for improving TB outcomes among patients HIV-TB in resource limited settings", yielding 288 relevant published articles that suggested that co-location of TB and HIV services was alone insufficient to substantially improve integrated services, recommending additional interventions such as quality improvement (QI) targeting health systems performance improvements for evaluation. In 2015, an expanded search for articles published between 2003 and 2015, evaluating impact of QI mediated integrated TB and HIV services on improved patient outcomes, using the terms 'Quality Improvement' AND 'resource constrained' AND 'HIV' AND tuberculosis, OR TB yielded zero findings. Since our search, two new trials have been published: the Merge trial found no patient outcome improvement with placement of additional staff supporting integrated HIV-TB care, and the TB-Fast Track trial found no short-term mortality reduction among PLWHA despite substantial increases in TB diagnosis and treatment coverage. Evidence guiding "how to" effectively implement integrated services at the frontline will optimize implementation of integrated services and help address persistently high mortality rates among HIV-TB coinfected individuals in resource limited settings. Added value of this study This is the first randomized trial to test a scalable HIV-TB integration strategy using QI methods. Despite the intervention, similarly high mortality rates among HIVTB co-infected patients were found. Demonstrating mortality benefit from health systems process improvements in real-world operational settings remains challenging, with this study highlighting the high level of health systems planning and organization required for delivery of complex QI supported HIV-TB integration interventions. Having rural clinics with their existing facility staff participate in this research enabled a better understanding of whether the QI intervention could be translated irrespective of resources or setting. Despite failing to show an impact on HIV-TB mortality rates the study found the health system to be responsive to strategic implementation support, showing overall improvements in performance. Implications of all the available evidence Growing evidence shows that affordable and sustainable QI strategies offer strengthened integrated HIV-TB service delivery through establishment of clear guidelines that address weaknesses in PHC clinic systems. This trial evaluated the effect of QI intervention to optimise delivery of integrated TB and HIV services and improve patient health outcomes. Incorporation of QI strategies into routine support for PHC clinics to sustain improved patient health outcomes yielded no added benefit to patient outcomes. |

Impact | The goal of ACC curriculum was to strengthen the South African governments' capacity in delivering high quality care to patients with complicated HIV and HIV/TB including those failing ART. Enhanced capacity through specialized clinical training, specialized clinical support, pharmaceutical services, laboratory services, strengthen referral pathways and collecting strategic information. This evolved into two streams : training around quality and case based approach . A national training ACC Curriculum was developed to provide health care professionals with the core knowledge and skills required to diagnose and manage unstable HIV patients with commonly observed opportunistic infections and other co-morbidities in addition to those failing antiretroviral therapy (ART). The curriculum consists of 4 main modules and 25 sub-modules (five of which are autodidactic pre-reading modules). 1. Module 1 - Core Topics, which encompassed the theoretical grounding in some key topics so that clinicians can apply this knowledge to clinical scenarios throughout the course 2. Module 2 - Management of the HIV-positive person with advanced disease. This module was designed to provide clinicians with the core knowledge and skills required to assess and manage an unstable patient with opportunistic infections and other comorbidities 3. Module 3 - Management of treatment failure and HIV drug resistance. This module is designed to equip clinicians with the core knowledge and skills required to identify and manage virologic failure and to be able to present practical management plans in specific clinical situations complicating virologic failure 4. Module 4 - Special challenges with antiretroviral therapy. This module will provide clinicians with the core knowledge and skills required to manage patients on ART with co-existing morbidities The training content developed included; slide sets, trainer manuals, learner manuals and knowledge assessment questions for each sub-module. These clinical resources were used to support the health care professionals in a clinic or hospital setting. Each training will orientate participants to these resources, and reference them throughout course activities. |
