An interventional study of Nurse-driven HIV screening for key populations combined with usual physician-directed diagnostic testing and Physician-directed diagnostic testing in Hiv and Nurse's Role, sponsored by Assistance Publique - Hôpitaux de Paris. Status unknown. Open to participants aged 18 Years to 64 Years. Per ClinicalTrials.gov, last updated 2020-03-06.
Sponsored by Assistance Publique - Hôpitaux de Paris · Not applicable, Interventional, and Screening
In France, 40% of newly diagnosed HIV infections are concentrated in the Paris metropolitan area.
Two key populations are mainly concerned: persons born in a foreign country and men who have sex with men. The randomized trial ANRS DICI-VIH (2014-2015) showed that nurse-driven HIV screening for key populations, supported by research staff, in 8 emergency departments (EDs) of the region, was effective in addition to diagnostic testing. The strategy advocated by the WHO and the recent French recommendations support the proposal of screening for key populations in the EDs. Thus, it is important to evaluate the impact and the feasibility of the implementation of this strategy on a large scale.
The aim is to evaluate the impact of a wide implementation of nurse-driven HIV screening by rapid test in key populations combined with usual physician-directed diagnostic testing (intervention strategy) compared to diagnostic testing alone (control strategy) in the usual practice of the EDs.
The strategies will be compared during two periods in 18 EDs of Paris metropolitan area following a stepped-wedge cluster randomized trial.
During intervention period, nurses will suggest performing an HIV rapid test to patients belonging to key populations according to the answers to a self-administered questionnaire.
Background:
In France, 40% of newly diagnosed HIV infections are concentrated in the Paris metropolitan area.
Two key populations are mainly concerned: persons born in a foreign country and men who have sex with men. The randomized trial ANRS DICI-VIH (2014-2015) showed that nurse-driven HIV screening for key populations, supported by research staff, in 8 emergency departments (EDs) of the region, was effective in addition to diagnostic testing. The strategy advocated by the WHO and the recent French recommendations of the National Health Authority (HAS) and expert group support the proposal of screening for key populations in the EDs. Thus, it is important to evaluate the impact and the feasibility of the implementation of this strategy on a large scale in a context where local institutions are taking initiatives to curb the epidemic ("Pour une Ile-de-France sans sida", "Vers Paris sans sida").
Our hypothesis is that nurse-driven HIV screening for key populations can be integrated to the consultants' care pathway as usual practice of the ED and assured over the long term in the Paris metropolitan area; this strategy combined with physician-directed diagnostic testing could reduce undiagnosed infections and help control the epidemic.
Primary objective:
The primary objective is to evaluate the impact of a wide implementation of nurse-driven HIV screening by rapid test in key populations combined with usual physician-directed diagnostic testing (intervention strategy) compared to diagnostic testing alone (control strategy) in the usual practice of the EDs.
Patients aged 18 to 64 years and visiting a participating ED for reasons other than a potential exposure to HIV within less than 48 hours will be included.
The primary outcome is the proportion of new HIV diagnoses among included patients.
Secondary objectives are to :
compare newly diagnosed HIV+ patients in the two groups in terms of :
Methods The strategies will be compared in 18 EDs of Paris metropolitan area during two periods. The start of the intervention strategy will be randomly allocated for each ED following a stepped-wedge cluster randomized trial.
EDs are selected according to the proportion of patients belonging to key populations in the patients they receive (data from two previous studies).
During intervention period, nurses will suggest performing an HIV rapid test to patients belonging to key populations according to the answers to a self-administered questionnaire.
The intervention period will last 3 to 11 months and the control period 0 to 8 months. Patients will participate up to 1 month if a follow-up is needed.
1,692 studies on the registry are indexed under Emergencies; 333 are open to participants now.
This study's planned enrollment of 487,000 is above the median of 145 across 931 interventional studies indexed under Emergencies.

Exclusion Criteria:
Nurse-driven HIV screening for key populations combined with usual physician-directed diagnostic testing (UD)
Procedure: Nurse-driven HIV screening for key populations combined with usual physician-directed diagnostic testing · Other: Physician-directed diagnostic testing
Other: Physician-directed diagnostic testing
A self-administered questionnaire on HIV exposure factors will be offered to all patients of ages 18-64 able to complete it. This questionnaire will be available in a paper-based format, electronic format on the patient phone or can be conducted verbally by the nurse. According to the answers, the nurses will suggest performing a rapid test to patients belonging to key populations. A finger-stick rapid HIV test will be performed and results will be disclosed by the nurse assisted by a physician if necessary. If needed, a follow-up visit with an infectious disease specialist will be scheduled within 72 hours.
Throughout the intervention, physicians will prescribe HIV tests to patients with HIV-related symptoms, following usual practice.
Proportion of new HIV diagnoses among included patients.
Time frame: At the end of the expected total duration of the inclusion period: 11 months in each ED
Feasibility of the screening strategy and its implementation
Feasibility of the screening strategy and its implementation based on: * proportion of distributed and completed self-administered questionnaires among the patients included and among the patients able to participate who were not known to be HIV positive, * the proportion of rapid tests offered by nurses among patients belonging to key populations, * the proportion of patients screened by nurses among patients who were offered a rapid test and among patients belonging to high-risk groups .
Time frame: At the end of the expected total duration of the inclusion period: 11 months in each ED
Effectiveness of the screening processes used by the caregivers, particularly the integration of the electronic questionnaire, and used by the patients as well as acceptability
Time frame: At the end of the expected total duration of the inclusion period: 11 months in each ED
Proportions of patients with a new diagnosis
Proportions of patients with a new diagnosis who had: * a follow up visit with an infectious disease specialist within 1 month, * a CD4 cell count greater or equal to 500 or 350/µL and no HIV-related symptoms, * an acute HIV infection.
Time frame: At the end of the expected total duration of the inclusion period: 11 months in each ED
Estimation through modelling of the number of new HIV diagnoses for different levels of coverage of the screening strategy in the Paris metropolitan area.
Time frame: At the end of the expected total duration of the inclusion period: 11 months in each ED
