“…Prevalence in heterosexuals was three times lower than in EPI-VIH and very similar to the prevalence found by another study conducted in primary care in Madrid [21]. This raises the question: is it appropriate to carry out programmes of this nature in locations frequented by lower risk groups?…”

“…In Spain, a previous study showed that the prevalence of previously undiagnosed HIV infection in patients aged 16–80 years who were having venipuncture in PC was 0.35% 14. Despite this, several studies have shown that general practitioners (GPs) frequently miss opportunities to test for HIV 15–19…”

ObjectiveTo estimate the prevalence of HIV testing among patients diagnosed with an indicator condition (IC) for HIV, seen in primary care (PC) in Catalonia, and to estimate the prevalence of HIV infection among those patients.DesignCross-sectional and population-based study in patients aged between 16 and 65 diagnosed with an IC within PC in Catalonia.MethodsData used in this study were extracted from a large population-based public health database in Spain, the Information System for the Development of Research in Primary Care (SIDIAP). All participants registered in SIDIAP from 1 January 2010 to 31 August 2012 and with a diagnosis of an IC were screened to identify those with an HIV test within the following 4 months.Results99 426 patients were diagnosed with an IC during the study period. In these patients, there were 102 647 episodes in which at least one IC was diagnosed. An HIV test was performed within 4 months in only 18 515 of the episodes in which an IC was diagnosed (18.5%). The prevalence of HIV infection was 1.46%. Women (OR 1.35, 95% CI 1.30 to 1.39), people aged 50 or over (OR 2.85, 95% CI 2.69 to 3.00) and patients having a single IC (OR 3.59. 95% CI 3.20 to 4.03) had the greatest odds of not having an HIV test.ConclusionsThe study highlights the persistence of missed opportunities for HIV testing within PC in Catalonia. Urgent engagement with PC professionals is required in order to increase HIV testing and prevent late HIV diagnoses.

“…Accuracy was assessed in the overall population enrolled in the study by calculating Sn, Sp, positive predictive value (PPV), and negative predictive value (NPV) using the gold standard confirmed HIV infection. Sample size was calculated for a maximum of 5300 rapid HIV tests assuming a hidden HIV infection in our environment of 0.35%, 23 an NPV of 100% and a difference of 0.25% for a power of 75%.…”
