title: Preexposure prophylaxis for HIV infection: healthcare providers' knowledge, perception, and willingness to adopt future implementation in the southern US.
abstract: BACKGROUND
  Understanding providers' perspective on preexposure prophylaxis (PrEP) would facilitate planning for future implementation.
  
  
  METHODS
  A survey of care providers from sexually transmitted disease and family planning clinics in South Carolina and Mississippi was conducted to assess their knowledge, perception, and willingness to adopt PrEP. Multivariable logistic and general linear regression with inverse propensity score treatment weights were used for analyses.
  
  
  RESULTS
  Survey response rate was 360/480 (75%). Median age was 46.9 years and a majority were women (279 [78%]), non-Hispanic white (277 [78%]), nonphysicians (254 [71%]), and public health care providers (223 [62%]). Knowledge about PrEP was higher among physicians compared with nonphysicians (P = 0.001); nonpublic health care providers compared with public health care providers (P = 0.023), and non-Hispanic whites compared with non-Hispanic blacks (P = 0.034). The majority of the providers were concerned about the safety, efficacy, and cost of PrEP. Providers' perceptions about PrEP were significantly associated with their sociodemographic and occupational characteristics. The willingness to prescribe PrEP was more likely with higher PrEP knowledge scores (adjusted odds ratio [aOR] 14.94; 95% confidence interval [CI] 3.21-69.61), older age (aOR 1.14; 95% CI 1.01-1.29), and in those who agreed that "PrEP would empower women" (aOR 2.90; 95% CI 1.28-6.61); and was less likely for "other" race/ethnicity versus white (aOR 0.23; 95% CI 0.07-0.76) and in those who agreed that "PrEP, if not effective, could lead to higher HIV transmission" (aOR 0.45; 95% CI 0.27-0.75).
  
  
  CONCLUSIONS
  To improve the acceptance of PrEP among providers, there is a need to develop tailored education/training programs to alleviate their concerns about the safety and efficacy of PrEP.
