“…This estimate is lower than that obtained (19%) from routine HIV testing among persons attending clinics for sexually transmitted infections (STI), in 2013 [ 18 ]. This estimate could be over-biased because of possible nondisclosure of HIV status due to convenience and discomfort in disclosing risky sexual behavior to healthcare professionals [ 19 , 20 ].…”

Objective:To estimate the size and characteristics of the undiagnosed HIV population in Italy in 2012 applying a method that does not require surveillance data from the beginning of the HIV epidemic.Methods:We adapted the method known as ‘London method 2’; the undiagnosed population is estimated as the ratio between the estimated annual number of simultaneous HIV/clinical AIDS diagnoses and the expected annual progression rate to clinical AIDS in the undiagnosed HIV population; the latter is estimated using the CD4+ cell count distribution of asymptomatic patients reported to surveillance. Under-reporting/ascertainment of new diagnoses was also considered. Also, the total number of people living with HIV was estimated.Results:The undiagnosed HIV population in 2012 was 13 729 (95% confidence interval: 12 152–15 592), 15 102 (13 366–17 151) and 16 475 (14 581–18 710), assuming no under-reporting/ascertainment, 10 and 20% of under-reporting/ascertainment, respectively. The percentage of undiagnosed cases was higher among HIV people aged below 25 years (25–28%), MSM (16–19%) and people born abroad (16–19%), whereas it was small among injection drug users (3%).Conclusion:The estimate of people in Italy with undiagnosed HIV in 2012 was in a plausible range of 12 000–18 000 cases, corresponding to 11–13% of the overall prevalence. The method is straightforward to implement only requiring annual information from the HIV surveillance system about CD4+ cell count and clinical stage at HIV diagnosis. Thus, it could be used to monitor if a certain prevention initiative lead to the reduction of the undiagnosed HIV population over time. It can also be easily implemented in other countries collecting the same basic information from the HIV surveillance system.

“…The benefits of using online panels in studies include quick access to a large participant pool and targeted recruitment directed by available demographic data (Erens et al, 2014; Heeren et al, 2008). Directed recruitment can include panelists who live in certain geographical locations (Miller et al, 2017) and rare and dispersed populations like sexual minorities (Datta, Hickson, Reid, & Weatherburn, 2013; Sell et al, 2015). Some studies have demonstrated that using panel vendors to recruit a sample reflective of the national population that meet certain criteria, for example, adults between the ages of 18 and 40, can occur rapidly (Craig et al, 2013; Erens et al, 2014; Heeren et al, 2008).…”

Using Panel Vendors for Recruitment Into a Web-Based Family Prevention Program: Methodological Considerations

et al. 2017

Use of online panel vendors in research has grown over the past decade. Panel vendors are organizations that recruit participants into a panel to take part in web-based surveys and match panelists to a target audience for data collection. We used two panel vendors to recruit families ( N = 411) with a 16- to 17-year-old teen to participate in a randomized control trial (RCT) of an online family-based program to prevent underage drinking and risky sexual behaviors. Our article addresses the following research questions: (1) How well do panel vendors provide a sample of families who meet our inclusion criteria to participate in a RCT? (2) How well do panel vendors provide a sample of families who reflect the characteristics of the general population? and (3) Does the choice of vendor influence the characteristics of families that we engage in research? Despite the screening techniques used by the panel vendors to identify families who met our inclusion criteria, 23.8% were found ineligible when research staff verified their eligibility by direct telephone contact. Compared to the general U.S. population, our sample had more Whites and more families with higher education levels. Finally, across the two panel vendors, there were no significant differences in the characteristics of families, except for mean age. The online environment provides opportunities for new methods to recruit participants in research studies. However, innovative recruitment methods need careful study to ensure the quality of their samples.

“…Datta et al 8 have taken this further, estimating the extent of STI testing away from usual HIV provider in a panel of MSM—this is relatively uncommon but not rare, though the extent probably varies by geography. The emergence of testing kits available over the internet will complicate STI prevention in this group still further.…”
