  • “My first step is to listen and be present with each family.”

As a former teacher and swim coach, I love making visits comfortable and educational for families. There is nothing better than helping families learn something new about how their bodies and minds work. I strive to build a relationship based on trust and open communication with all the families I work with. I promise that no question is too weird or crazy.

My goal is to ensure that every family leaves our visits with a clear understanding of their questions or concerns, and that they feel a sense of relief knowing that I am there to support them no matter what. I chose pediatrics because I love the variety of working with children of all ages, from newborns to young adults. I have a particular interest in working with adolescents and young adults, as well as LGBTQ youth and families.

Adolescent Health Providers' Willingness to Prescribe Pre-Exposure Prophylaxis (PrEP) to Youth at Risk of HIV Infection in the United States JOURNAL OF ADOLESCENT HEALTH Hart-Cooper, G. D., Allen, I., Irwin, C. E., Scott, H. 2018; 63 (2): 24244


HIV disproportionately affects young men who have sex with men. Pre-exposure prophylaxis (PrEP) can prevent HIV acquisition; however, youth access to PrEP is limited by provider willingness to prescribe PrEP.We conducted an online survey of clinicians working with adolescents (aged 13-17 years) and young adults (aged 18-26 years) in the United States through the Society of Adolescent Health and Medicine. We used multivariate logistic regression to assess provider beliefs associated with willingness to provide PrEP.Nearly all (93.2%) providers had heard of PrEP, and 57 (35.2%) had prescribed PrEP. While almost all providers (95%) agreed that PrEP prevents HIV, fewer were willing to prescribe to young adults (77.8%) or adolescents (64.8%). Willingness to prescribe PrEP was strongly associated with the belief that providers had enough knowledge to safely provide PrEP to adolescents (OR 2.11, confidence interval [CI]: 1.18-3.76, p=.01) and young adults (odds ratio 5.19, CI: 2.15-12.50, p.001), and that adolescents would be adherent (odds ratio 3, CI: 1.30-6.90, p=.01). Response rate was 17%.Almost all providers had heard of PrEP and most providers were willing to prescribe PrEP. Provider education and tools to promote provider self-efficacy and adolescent adherence might improve provider willingness to provide PrEP.

Low Viral Suppression and High HIV Diagnosis Rate Among Men Who Have Sex With Men With Syphilis - Baltimore, Maryland SEXUALLY TRANSMITTED DISEASES Cooley, L. A., Pearl, M. L., Flynn, C., Ross, C., Hart-Cooper, G., Elmore, K., Blythe, D., Morgan, J., Oster, A. M. 2015; 42 (4): 22631


The burden of syphilis and HIV among gay, bisexual, and other men who have sex with men (MSM) in Baltimore, Maryland, is substantial. Syphilis and HIV surveillance data were analyzed to characterize MSM with syphilis, including those with repeat infection and HIV coinfection, to strengthen prevention efforts.MSM 15 years or older from Baltimore City or County diagnosed as having early syphilis in 2010 to 2011 were included. Those previously treated for syphilis in 2007 to 2011 were considered to have repeat syphilis infection. HIV surveillance data were used to identify HIV coinfection and assess viral suppression. For MSM not diagnosed as having HIV at or before their syphilis diagnosis, annual HIV diagnosis rates were estimated, using Baltimore City data.Of 460 MSM with early syphilis in 2010 or 2011, 92 (20%) had repeat infection; 55% of MSM with a single diagnosis and 86% with repeat infection were HIV coinfected. Among MSM diagnosed as having HIV, viral suppression was low (25%, or 46% of those with a viral load reported). Among Baltimore City MSM without a prior HIV diagnosis, estimated annual HIV diagnosis rates were high (5% for those with 1 syphilis diagnosis, 23% for those with repeat infection).Baltimore-area MSM with syphilis, particularly those with repeat infection, represent a unique population for whom coinfection with HIV is high. Increasing frequency of syphilis and HIV testing among Baltimore area MSM with a syphilis diagnosis and prioritizing HIV-infected MSM with syphilis in efforts to achieve viral suppression may improve outcomes locally for both infections.

Circumcision of Privately Insured Males Aged 0 to 18 Years in the United States PEDIATRICS Hart-Cooper, G. D., Tao, G., Stock, J. A., Hoover, K. W. 2014; 134 (5): 95056


Male circumcision confers protection against HIV, sexually transmitted infections, and urinary tract infections. Compared with circumcision of postneonates (>28 days), circumcision of neonates is associated with fewer complications and usually performed with local rather than general anesthesia. We assessed circumcision of commercially insured males during the neonatal or postneonatal period.We analyzed 2010 MarketScan claims data from commercial health plans, using procedural codes to identify circumcisions performed on males aged 0 to 18 years, and diagnostic codes to assess clinical indications for the procedure. Among circumcisions performed in the first year of life, we estimated rates for neonates and postneonates. We estimated the percentage of circumcisions by age among males who had circumcisions in 2010, and the mean payment for neonatal and postneonatal procedures.We found that 156,247 circumcisions were performed, with 146,213 (93.6%) in neonates and 10,034 (6.4%) in postneonates. The neonatal circumcision rate was 65.7%, and 6.1% of uncircumcised neonates were circumcised by their first birthday. Among postneonatal circumcisions, 46.6% were performed in males younger than 1 year and 25.1% were for nonmedical indications. The mean payment was $285 for a neonatal and $1885 for a postneonatal circumcision.The large number of nonmedical postneonatal circumcisions suggests that neonatal circumcision might be a missed opportunity for these boys. Delay of nonmedical circumcision results in greater risk for the child, and a more costly procedure. Discussions with parents early in pregnancy might help them make an informed decision about circumcision of their child.

Provider Barriers Prevent Recommended Sexually Transmitted Disease Screening of HIV-Infected Men Who Have Sex With Men SEXUALLY TRANSMITTED DISEASES Carter, J. W., Hart-Cooper, G. D., Butler, M. O., Workowski, K. A., Hoover, K. W. 2014; 41 (2): 13742


HIV-infected men who have sex with men (MSM) are at increased risk for transmitting and acquiring sexually transmitted diseases (STDs). Guidelines recommend at least annual screening of HIV-infected MSM for syphilis and for chlamydia and gonorrhea at exposed anatomical sites, to protect their health and their sexual partners' health. Despite these guidelines, STD screening has been suboptimal, with very low nongenital chlamydia and gonorrhea testing rates. Our objective was to better understand barriers encountered by HIV care providers in adhering to STD screening guidelines for HIV-infected MSM.We conducted 40 individual semistructured interviews with health care providers (physicians, midlevel providers, nurses, and health educators) of HIV-infected MSM at 8 large HIV clinics in 6 US cities. Providers were asked about their STD screening practices and barriers to conducting sexual risk assessments of their patients. Emerging themes were identified by qualitative data analysis.Although most health care providers reported routine syphilis screening, screening for chlamydia and gonorrhea at exposed anatomical sites was less frequent. Obstacles that prevented routine chlamydia and gonorrhea screening included time constraints, difficulty obtaining a sexual history, language and cultural barriers, and patient confidentiality concerns.Providers reported many obstacles to routine chlamydia and gonorrhea screening. Interventions are needed to help to mitigate barriers to STD screening, such as structural and patient-directed health services models that might facilitate increased testing coverage of these important preventive services.
