Study Overview
Brief Summary
To reduce late HIV diagnosis that remains common in France, the national health agency has promoted non-targeted HIV screening in health care settings, including emergency departments (EDs). In our previous survey, non-targeted nurse-driven HIV screening by rapid tests was feasible, well-accepted but identified only a few new HIV diagnoses mostly among patients at high-risk. Our findings, consistent with results from other international groups, suggest that a targeted strategy could be feasible, efficient and cost-effective with fewer tests required. However, the feasibility and the efficacy of this strategy remain unknown in France.
The main aim of the present study is to compare the efficacy of 2 strategies: 1) the combination of the nurse-driven HIV targeted screening and the current practice (physician-directed HIV diagnostic testing) versus 2) the current practice alone.
The strategies will be compared during 2 randomly assigned periods (cluster randomization and cross-over) in 8 EDs of metropolitan Paris.
During targeted period, nurses will offer screening to all patients at EDs, aged 18-64 years old, identified as high-risk by a self-administered questionnaire, not know to be HIV positive, not being seen for post-exposure prophylaxis or unstable medical illness, and accepting to participate by providing an informed consent.
In case of confirmed reactive rapid test result, a follow-up visit with an on-site infectious disease specialist will be arranged within the following 48 hours.
Detailed Description
Background :
Despite easy and free access to HIV testing services and 5 million of tests per year performed, late diagnosis remains common in France with one-third of HIV infections diagnosed associated with AIDS or CD4 lymphocyte counts of less than 200/μL. To improve early detection, the national health agency has promoted non-targeted HIV screening in health care settings, including emergency departments (EDs), in addition to diagnostic testing routinely performed by physicians. In our previous survey conducted in 2009-2010 in 29 EDs of the metropolitan Paris area, non-targeted nurse-driven HIV screening by rapid tests was feasible, well-accepted but identified only a few new HIV diagnoses mostly among patients at high-risk. Our findings, consistent with results from other international groups, suggest that a targeted strategy could be feasible, efficient and cost-effective with fewer tests required. However, the feasibility and the efficacy of this strategy remain unknown in France.
Primary objective :
The aim of the present study is to compare the efficacy of two strategies: 1) the combination of the nurse-driven HIV targeted screening and the current practice (physician-directed HIV diagnostic testing) versus 2) the current practice alone (physician-directed HIV diagnostic testing).
The main outcome measure is the number of patients with newly identified HIV infection among the number of 18-64 years patients visited EDs (apart from being seen for prophylaxis after exposure to HIV) during the inclusion periods.

Outcomes
Primary Outcomes
Number of patients with newly identified HIV infection among the number of 18-64 years patients visited EDs (apart from being seen at ED for prophylaxis after exposure to HIV) during the inclusion periods
Time Frame: At the end of the expected total duration of the inclusion periods : up to 9 months in each center
Secondary Outcomes
- Linkage into care of patients with newly diagnosed infection (Follow-up visit with an on-site infectious disease specialist)(In the 3 months after the HIV screening at the emergency department)
- Early detection of HIV (Proportion of patients with CD4>500/mm3, >350/mm3 and >200/mm3, and without HIV-related symptoms at presentation)(In the 3 months after the HIV screening at the emergency department)
- Feasibility of the nurse-driven HIV screening (Proportion of : filled-questionnaires, proposition of the nurse-driven HIV screening, acceptation by patients and HIV rapid tests done by nurses)(At the end of the expected total duration of the inclusion periods : up to 9 months in each center)
- Number of new HIV positive tests among the total number of tests(At the end of the expected total duration of the inclusion periods : up to 9 months in each center)
- Cost-effectiveness of the 2 compared strategies(At the end of the expected total duration of the inclusion periods : up to 9 months in each center)
- Acceptability of the nurse-driven HIV screening by the patients (additional questionnaire proposed to patients in 4 centers)(Questionnaire proposed at ED for each patient after the main study questionnaire during inclusion period. Analysis after the expected total duration of the inclusion periods : up to 9 months in each center)
- Acceptability of the nurse-driven HIV screening by the caregivers (Interviews with nurses, nurse managers, physician doctors and hospital managers)(Before and after the expected total duration of the inclusion periods : up to 9 months in each center)
