Preparing for PrEP: perceptions and readiness of canadian physicians for the implementation of HIV pre-exposure prophylaxis.

ABSTRACT: Recent evidence has demonstrated the efficacy of pre-exposure prophylaxis (PrEP) for HIV prevention, but concerns persist around its use. Little is known about Canadian physicians' knowledge of and willingness to prescribe PrEP. We disseminated an online survey to Canadian family, infectious disease, internal medicine, and public health physicians between September 2012-June 2013 to determine willingness to prescribe PrEP. Criteria for analysis were met by 86 surveys. 45.9% of participants felt "very familiar" with PrEP, 49.4% felt that PrEP should be approved by Health Canada, and 45.4% of respondents were willing to prescribe PrEP. Self-identifying as an HIV expert (odds ratio, OR?=?4.1, 95% confidence interval, CI?=?1.6-10.2), familiarity with PrEP (OR?=?5.0, 95%CI?=?1.3-19.0) and having been asked by patients about PrEP (OR?=?4.0, 95%CI?=?1.5-10.5) were positively associated with willingness to prescribe PrEP on univariable analysis. The latter two were the strongest predictors on multivariate analysis. Participants cited cost and efficacy as major concerns. 75.3% did not feel that information had been adequately disseminated among physicians. In summary, Canadian physicians demonstrate varying levels of support for PrEP and express concerns about its implementation. Further research on real-world effectiveness, continuing medical education, and clinical support is needed to prepare physicians for this prevention strategy.

Project description:INTRODUCTION:The World Health Organization, while recommending pre-exposure prophylaxis (PrEP) for HIV-negative pregnant and postpartum women in HIV high-burden settings, advocates for continued safety evaluation of PrEP in this population. METHODS:The PrEP Implementation in Young Women and Adolescents (PrIYA) program delivered PrEP to pregnant and postpartum women integrated within routine maternal and child health clinics (MCH) at 16 sites in Western Kenya. PrEP exposure and perinatal outcome data were collected among women obtaining postnatal services during programme evaluation. PrEP use was self-reported and confirmed with clinical records. Perinatal outcomes including gestational age at birth, birthweight, congenital malformations and infant growth outcomes were abstracted from clinical records for mother-infant pairs attending the six week visit. Associations between infant outcomes and maternal prenatal PrEP use were assessed using univariate and multivariate logistic and linear regression. RESULTS:The PrIYA evaluation identified 1530 postpartum mother-infant pairs with data on prenatal PrEP exposure: 206 with prenatal PrEP use, 1324 without. Median maternal age was 24 years in both groups. PrEP users (any reported PrEP use) were significantly more likely to report HIV risk factors such as: intimate partner violence, sexually transmitted infections and having a partner with positive or unknown HIV status. Most mothers initiated PrEP during the second trimester (n = 116, 57%) and used PrEP for more than one month (n = 110, 58%). The mean birthweight was 3.3 kg and gestational age at birth was 38.5 weeks in both groups. There were no major differences between PrEP exposed and unexposed infants in rates of preterm birth and low birthweight. There were no congenital malformations identified in the PrEP-exposed group and five reported in the PrEP unexposed group. At six weeks postpartum, infants in both groups had similar growth. No differences in infant outcomes were found by duration PrEP exposure, trimester of PrEP initiation, a subset analysis of women 15 to 24 years old or in multivariate analyses. This analysis demonstrates that monitoring of infant outcomes is feasible within large-scale programmatic implementation of PrEP among pregnant and postpartum populations. CONCLUSIONS:Pregnancy outcomes and early infant growth did not differ by PrEP exposure.
