Trial Outcomes & Findings for Two Approaches to Routine HIV Testing in a Hospital Emergency Department (NCT NCT00502944)

NCT ID: NCT00502944

Last Updated: 2012-07-19

Results Overview

We define linkage to care as attendance at a first HIV clinic appointment where the following 3 events occur: 1) introduction to an HIV care primary provider; 2) receipt of confirmatory Western Blot HIV test results; and 3) phlebotomy for CD4 cell count and HIV RNA level.

PRIMARY outcome

Timeframe: Assessed within 8 weeks after receipt of reactive rapid HIV test results

Population: DSMB recommended the trial be ended early for likely inability to obtain this primary outcome. Thus the outcomes reported in paper are the secondary and other pre-specified outcomes listed.

We define linkage to care as attendance at a first HIV clinic appointment where the following 3 events occur: 1) introduction to an HIV care primary provider; 2) receipt of confirmatory Western Blot HIV test results; and 3) phlebotomy for CD4 cell count and HIV RNA level.

SECONDARY outcome

Timeframe: Assess on day subject enrolled into the study

Population: Intention to treat analysis

We defined the overall rapid HIV testing rate as the number of participants tested for HIV using the rapid test among those randomized to potentially be tested in each arm.

OTHER_PRE_SPECIFIED outcome

Timeframe: Assess on day subject enrolled into the study

The offer rate of the HIV test was defined as the proportion of enrolled study participants who were actually offered a test.

OTHER_PRE_SPECIFIED outcome

Timeframe: Assess on day subject enrolled into the study

Population: Number of participants analyzed equals the number of participants offered a rapid HIV test. Many participants left the ED before the opportunity was available to offer the test.

Acceptance of the HIV test was defined as the proportion of study participants who received the HIV test among those offered the test.
