[Cobatest network: users' characteristics of community-based voluntary,counselling and testing centres in Spain.]

The COBATEST network (European network of community-based voluntary, counselling and testing centers) allows standardized collection of information to monitor HIV testing at these centers. The objective was to describe the performance of the Spanish centers of the COBATEST network and the epidemiological profile of its users, and to analyze the factors associated with having an earlier HIV test.

Descriptive analysis of the data collected in the 19 Spanish centers that used the common information collection tools during the year 2015. A multivariate logistic regression model was used to identify factors associated with having an earlier test.

A total of 6,077 HIV rapid tests were performed and 1.8% were reactive (3.0% MSM, 3.1% SW, 2.3% PWID, 0.6% heterosexual). 82.1% of the reactives were referred to perform a confirmatory test and 94 (97.9%) were HIV positive, of whom 54% were diverted to the health system. 38% said they had never been tested for HIV. Factors associated with having a previous HIV test were: being over 20 years old; being HSH, SW, or PWID; being foreign; having used condoms at the last penetration; having had an STI in the last year; and having been in jail.

The results show the great potential of these services to reach people who have never been tested for HIV. The HIV cases are concentrated in vulnerable groups. It is necessary to improve the linkage of diagnosed people to health care services.
