Evaluation

Site evaluation

Each site that integrates the routine offer of testing is evaluated on the following metrics: number of tests performed; number of positives; percent positivity; and percentage change in testing volumes since implementation. All sites also receive a quarterly report card indicating their progress. This report card, available in the Program Materials section, lists the number of laboratory tests performed, the number of rapid tests performed, and the number of HIV-positive results. These reports also include the overall number of new HIV diagnoses that have occurred in the Vancouver Coastal Health region since July 2010. This allows sites that have not had any positive diagnoses to see that expanded access to testing is having an impact on the number of new diagnoses.

As of February 2013, there has been a 57 percent increase in HIV testing across all sites. The overall positivity rate is 0.4 percent, well above the cost-effectiveness threshold1 for a routine HIV testing initiative. Primary healthcare clinics have the highest percent positivity at 0.5 percent.

Data on the stage of disease at diagnosis, the socio-demographics of people newly diagnosed with HIV and data on how long it took to link a person to care are also collected. These data are gathered to determine the overall success of the Vancouver STOP Project in diagnosing people early and linking them to care effectively, both of which were goals of the overall STOP HIV/AIDS Project.

Team evaluation

The effectiveness of the Targeted Testing Team’s services is measured through surveys completed by testing sites.  The surveys are used to evaluate the tools the team uses as well as the support the team offers.

The team also holds focus groups that ask staff who have integrated the routine offer of HIV testing to reflect on how the routine offer of HIV testing is received by patients and perceived by staff. Sites are also asked to reflect on how prepared they feel to offer HIV testing, the challenges and benefits of point-of-care testing, ongoing barriers to implementing HIV testing, and recommendations to other sites implementing HIV testing.
