Scientific titleEffectiveness of human immunodeficiency virus (HIV) screening in Primary Care: a cluster randomised controlled trial (RCT) and economic analysis
Study acronymRHIVA2
Study hypothesisThe primary objective is to demonstrate that rapid human immunodeficiency virus (HIV) testing integrated into the GP registration health check, when combined with an educational package for health care professionals, increases the rate of HIV testing and diagnoses over and above usual care.

The secondary objective is to demonstrate an increase in proportion of HIV cases diagnosed during early stages of infection, defined as a CD4 count higher than 200 cells per cubic millimetre.
Ethics approval(s)Camden and Islington Community Research Ethics Committee, 18/11/2009, ref: 09/H0722/67
ConditionHuman immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS)
InterventionIntervention surgeries:
The formative phase for intervention surgeries will include the following:
1. Analysis of the educational requirements for GPs nurses and health care assistants
2. Provision of training in performing the rapid point of care HIV test
3. Setting up the operating procedure for HIV testing as an integrative part of the new patient health check
4. Confirmation of referral pathways for newly diagnosed patients into specialist care
5. Establishing the role of the HIV specialist nurse as the key figure to facilitate communication about newly diagnosed patients between clinicians including GPs and the HIV specialist team, the Virology lab and the researchers

Follow-up procedures:
Any patient with a reactive HIV rapid test will be seen by the GP immediately for information; a further test and specialist follow up. The HIV specialist nurse, a member of the clinical management team at the Department of Sexual Health at Homerton Hospital, will liaise with both GP surgeries and the Department of Virology at Barts and The London NHS Trust at least fortnightly to minimise the loss of patients followed up in specialist care. If a patient fails to attend specialist follow up, the HIV research nurse will make appropriate attempts to contact the patient.

Laboratory assessments:
1. Rapid HIV test: The rapid HIV test will be performed using the INSTI HIV-1/HIV-2 Rapid Antibody Test (bioLytical Laboratories, Canada) according to the manufacturer's instructions. The INSTI test device has CE-marking and detects antibodies to the Human Immunodeficiency Virus Type 1 and Type 2. Briefly, 50 micro litres of blood drawn from a finger prick using a pipette is mixed with a Sample Diluent and poured onto a Sample Membrane. Signals are visualised by applying a Colour Developer onto the membrane and by de-staining the background using a Clarifying Solution. Results are available in 60 seconds. A single dot (control) on the Sample Membrane indicates a negative result; an additional blue test dot suggests HIV infection, and any other staining pattern including the absence of any signal indicates an invalid result. For further information, please see http://www.biolytical.com/ourtechnology.html.
2. CD4 counts and viral parameters including HIV viral load, clade and genotype of the virus

Laboratory assessments of immunological and viral endpoints specified in section 8.1.2.1 of this protocol will be performed according to approved standard operating procedures.

Total duration of treatment and follow up:
For patients testing reactive, invalid or inderminate on the Rapid HIV Fingerprick test treatment and follow up could be between 2 weeks and 2 months depending on result. In cases where patients test non reactive, treatment will last only a few moments.

Control Surgeries:
No treatment. Control surgeries will be informed about the most recent specialist recommendations for HIV testing and receive support from the HIV specialist nurse throughout the study period.
Intervention typeOther
Primary outcome measureRates of new HIV diagnoses: numbers of rapid and standard HIV tests done in new patient health checks

Outcomes are measured quarterly.
Secondary outcome measuresImmunological outcomes:
1. Numbers of patients diagnosed during early HIV infection defined as CD4 count higher than 200 cells per cubic millimetre blood

Viral outcomes:
2. HIV viral load, clade and genotype of the virus at the time of diagnosis as predictors of disease progression

Health service use:
3. Numbers of registering patients
4. Numbers of standard HIV tests done opportunistically
5. Numbers of New Patient Health Checks carried out

Economic outcomes:
6. Cost-effectiveness of the intervention compared to standard of care

Outcomes are measured quarterly.
