Background and study aims
In Africa, chronic diseases such as high blood pressure (hypertension) and high blood sugar (diabetes) are now common and require treatment for life. HIV-infection is also common and also requires life-long treatment.
At the moment, in most African countries, health services for hypertension, diabetes and HIV-infection are provided in separate clinics or on separate days. Given the growing need for these services, the researchers don’t know if this is the best way or whether services for these conditions should be provided together (i.e. all provided in one clinic). The researchers call bringing these services under one roof, integrated care. Integrating these services under one roof could be easier for patients and for health services but it might put pressure on the health worker seeing people with different conditions.
The goal is to compare a model of integrated care for people living with HIV-infection, diabetes or hypertension against the current standard model of separate clinics for each of these conditions.
The researchers will compare these models in terms of various health indicators measured among people with these conditions and the costs that both patients and the health services incur.
The researchers are working closely in partnership with health policy makers in Tanzania and Uganda. They will be the principal users of the research. They will use the information from the study to decide how future health care should be organised for chronic conditions.
Who can participate?
Adults over 18 years, with confirmed HIV-infection, diabetes, hypertension or any combination of these
What does the study involve?
The researchers want to generate clear evidence that can feed into consideration of future policy. In this trial, some health facilities will be asked to provide integrated care, and some will continue with the current stand-alone care. Health facilities will be randomly assigned (i.e. by chance) to deliver one of the two options of care. This is called a cluster-randomised trial.
Within each health facility, patients will be selected systematically for the study. They will be invited to join if they meet the criteria (for example that they live within reasonable distance). They will receive care from the regular health workers who will receive refresher training on how to manage HIV-infection, hypertension and diabetes. Participants will be followed up over 12 months to work out how well their disease has been managed, the financial costs that they incurred to come to the health facility, costs incurred by the health services to provide the care, and other indicators.
The researchers plan to enrol 32 health facilities in the two countries and a total of about 220 participants at each facility with one of the target diseases (HIV-infection, high blood pressure or high blood sugar). These participants will be included in the main overall evaluation of the two models of care.
What are the possible benefits and risks of participating?
There are no direct or immediate benefits to participants but the information from this study will help the Ministry of Health to decide on how to provide service for people who need chronic care.

1. Medical Research Council/Uganda Viral Research Institute/London School of Hygiene & Tropical Medicine Uganda Research Unit (Uganda)

| Scientific title | Integrating HIV, diabetes and hypertension services in Africa: a cluster-randomised trial in Tanzania and Uganda |
| Study acronym | INTE-AFRICA Trial |
| Study objectives | Integration of chronic care services will lead to improved outcomes for people living with diabetes or hypertension and will not compromise outcomes among people living HIV-infection. |

| Health condition(s) or problem(s) studied | HIV-infection, diabetes, or hypertension or combinations of these conditions |
| Intervention | Experimental arm: Integrated health service provision at health facilities providing primary care for HIV infection, diabetes and hypertension. Control arm: standard care – separate stand-alone services for HIV infection, diabetes or hypertension. Integration will involve - A single one-stop clinic where patients with either HIV infection, diabetes or hypertension will be managed. Patients can have one or more of these conditions. - They will be seen and managed by the same clinicians, nurses, counsellors and other staff - There will be one pharmacy where dispensing is integrated - Patient records will be the same – a similar card will be used for all patients - Laboratory tests will be done by the same laboratory service Participants will be followed up from enrolment into the study for a period of 12 months. Randomisation of the health facilities will be stratified in each country by location, type of health facility (as defined by the clinical infrastructure available at the health facility) and by patient load at the health facility (i.e. the numbers of patients attending the facility on a monthly basis). Within each stratum, the researchers will randomise in a 1:1 ratio to either the experimental integration arm or the standard care arm using a computer-generated randomisation list. |
| Intervention type | Mixed |
| Primary outcome measure | 1. Retention in care for patients on diabetes and hypertension management measured using patient records at 12 months 2. Plasma viral load suppression among persons HIV-infected measured using lab test (suppression will be defined as plasma viral load < 1000 copies per ml.) at 12 months |
| Secondary outcome measures | 1. Cost-effectiveness measured using a decision analytical model at 12 months 2. Biomedical indicators measured at baseline and 12 months 2.1. Fasting blood glucose 2.2. HbA1c 2.3. Blood pressure (mmHg) 3. Clinic usage (aggregated data on day-to-day patient numbers, time spent at clinic by patients, and basic indicators of quality of service such as consultation times) measured over 12 months |

| Publication and dissemination plan | INTE-AFRICA is designed to generate the evidence to inform scale up of integrated chronic care services. The research programme will work closely with policy makers and senior programme managers in both countries. We will provide them with the findings and support them in the decision that they take. If the trial demonstrates the effectiveness of integrated care, we will support the health facilities to scale this up. We will share protocols on integration and monitor the scale up to record the lessons learnt to facilitate other health facilities to follow. The findings will also be published in at least one peer-reviewed journal and data will be made accessible to other bodies for further dissemination. |
| IPD sharing plan | The datasets generated during and/or analysed during the current study will be stored in a non-publically available repository. The LSTM subscribes to the FAIR Guiding Principles for scientific data management and stewardship. All datasets from research are committed to the Electronic Data Repository with associated study documentation as well as metadata. Currently, this repository is only accessible to staff. Interested parties can request for metadata of projects in certain disease areas or keywords by contacting the Data controller via email. |
