Outcome of an HIV education program for primary care providers: Screening and late diagnosis rates

Abstract

Background Late HIV diagnosis remains one of the challenges in combating the epidemic. Primary care providers play an important role in screening for HIV infection. Our study aims to evaluate the relationship between knowledge and barriers to HIV testing and screening outcomes. The impact of an education program for primary care providers, towards improving HIV testing and late diagnosis rates, is also assessed. Methods A self-administered questionnaire that was developed within the framework of the European project OptTEST was used to examine HIV knowledge and barriers to HIV testing scores before and after being involved in an HIV education program. A quasi-experimental design with pre- and post-intervention measures was performed to investigate its impact. We performed multivariable logistic regression analysis to assess the relationship between variables for the HIV testing offer. Results A total of 20 primary care centers and 454 primary care staff were included. Baseline OptTEST results showed that more knowledgeable staff offered an HIV test more frequently (OR 1.07; CI 95% 1.01–1.13; p = 0.027) and had lower barrier scores (OR 0.89; CI 95% 0.77–0.95; p = 0.005). Nurses had lower scores in knowledge-related items (OR 0.28; CI 95% 0.17–0.46; p<0.001), but higher scores in barrier-related items than physicians (OR 3.28; CI 95% 2.01–5.46; p<0.001). Specific centers with more knowledgeable staff members had a significant association with a greater level of new HIV diagnosis rates (OR 1.61; CI 95% 1.04–2.49; p = 0.032). After the intervention, we found that 12 out of 14 individual questions showed improved scores. In the 6 months after the training program, we similarly found a higher HIV testing rate (OR 1.19; CI 1.02–1.42; p = 0.036). Conclusions This study highlights the association between knowledge and barriers to HIV testing, including HIV testing rates. It shows that it is possible to modify knowledge and reduce perceived barriers through educational programs, subsequently improving HIV screening outcomes.

Hepatitis C and HIV combined screening in primary care: A cluster randomized trial

“…Previous studies in the same health area found rates of new HIV diagnoses higher than 2‰, 22,23 while five years later the incidence was 0.44‰. Although no definitive conclusions can be drawn, these data may indicate that the low prevalence of chronic occult infection currently existing in our area may be due to the effectiveness of screening programmes implemented in recent years, 18,23 as well as to the progressive decrease in the global incidence of HIV infection 24 . Moreover, patient characteristics included in the study could explain in part this low number of HIV diagnoses, since there is a high representation of women and people over 50 years of age.…”

Current evidence on the adoption of indicator condition guided testing for HIV in western countries: A systematic review and meta-analysis

“…Moreover, an evaluation of ICguided HIV testing recommendations in specialty guidelines in the UK and Europe revealed that the majority of IC guidelines do not recommend HIV testing, and physicians are not always aware of current HIV testing recommendations. [18,37] This is supported by the observation that the highest HIV test ratio were found in TB, HBV and HCV; HIV testing is recommended most prominently in the specialty guidelines for these conditions, and as pulmonologists and gastroenterologists commonly collaborate with infectious disease specialists, they may be more likely to focus on possible underlying HIV. Adoption of HIV testing in specialty guidelines and creating awareness of this strategy among involved specialties is an important first step to optimize testing.…”

HIV and HCV screening by non-infectious diseases physicians: can we improve testing and hidden infection rates?

“…Universal opt-out HIV testing programs offered to all general medical admissions in a hospital have proven effective in improving HIV diagnosis in several studies ( 19 ). Formative strategies have proven to be helpful in primary care ( 17 , 18 , 20 ). However, data on these strategies in hospital settings are scarce.…”
