Matthew J. Mimiaga; Andrew D. Fair; Ashley M. Tetu; David S. Novak; Rodney VanDerwarker; Thomas Bertrand; Stephan Adelson; Kenneth H. Mayer

US men who have sex with men (n=1848) completed an online questionnaire about their willingness to use Internet-based partner notification. Eighty-one percent reported that it would be important to them to receive a partner notification e-mail if they had been exposed to a sexually transmitted infection. Seventy percent reported that if infected, they would use a public health specialist to inform partners of possible exposure through Internet notification. There was broad acceptance of Internet partner notification by at-risk US men who have sex with men, including a willingness to receive or initiate a notification e-mail.

Background: In the past decade, increases in syphilis and rectal gonorrhea have been reported among men who have sex with men (MSM) in the United States; however, limited sexually transmitted disease (STD) positivity data are available on MSM who receive their healthcare from primary care or general medical clinics. The current study sought to elucidate STD positivity in asymptomatic MSM seen at the largest primary care clinic for MSM in New England and to describe STD test positivity by reason for STD testing. Methods: As part of the Centers for Disease Control and Prevention’s MSM Prevalence Monitoring Project, all medical visits between 2003 and 2004 (n = 21,927) among MSM attending Fenway Community Health (Boston) were reviewed. The prevalence of positive STD tests (chlamydia, gonorrhea, and syphilis reactivity) was determined and analyzed by demographic characteristics, HIV status, symptoms, and reason for testing. Results: Overall, 23.4% of MSM visits included STD testing during the observation period. Their mean age was 39 years (range: 18–65 years); 84% were white, 5% were black, and 5% were Hispanic. Sixty-five percent of MSM tested were asymptomatic with 7% of asymptomatic MSM testing positive for at least one STD. STD prevalence varied by reason for STD testing: 4.4% of MSM routinely screened had at least one STD, compared to 6.9% of MSM who reported having high risk sex in the preceding 3 months, and 17% of MSM reporting an exposure to an STD. Among all asymptomatic MSM tested, 1.0% had urethral gonorrhea; 1.7% had pharyngeal gonorrhea; 5.6% had rectal gonorrhea; 2.2% had urethral chlamydia; and 4.3% were seroreactive for syphilis. Conclusions: Rectal gonorrhea and syphilis seropositivity were frequently diagnosed in asymptomatic MSM; STD prevalence was highest in MSM tested due to an STD exposure or reporting high-risk sex, underscoring the need to promote routine screening in high risk MSM populations.

Objectives: This study assessed the acceptability and perceived utility of Internet-based partner notification (PN) of sexually transmitted disease (STD) exposure for men who have sex with men (MSM) by human immunodeficiency virus (HIV) serostatus. Study Design: We recruited 1848 US MSM via a banner advertisement posted on an MSM website for meeting sexual partners between October and November 2005. Results: Even though there was broad acceptance of a PN e-mail across HIV serostatus groups, HIV-infected men rated the importance of each component (e.g., information about where to get tested/treated, additional education regarding the STD exposed to, a mechanism for verifying the authenticity of the PN e-mail) lower than HIV-uninfected or status-unknown participants (all Ps <0.01). Additionally, HIV-infected participants were less likely to use the services offered within a PN e-mail (if they were to receive an e-mail notifying them of possible STD exposure in the future), and were less likely to inform their partners of possible STD exposure via an Internet notification system in the future (all Ps <0.01). A similar trend emerged about men who reported not having a previous STD compared with those who did. Men who reported no previous STD found Internet PN more acceptable. Conclusions: Overall, this study documents broad acceptance of Internet PN by at-risk MSM, regardless of HIV serostatus, including a willingness to receive or initiate PN-related e-mail. If public health officials consider using Internet notification services, they may need to anticipate and address concerns of HIV-infected MSM, and will need to use a culturally-sensitive, social marketing campaign to ensure that those who may benefit from these services are willing to use this modality for PN. Internet PN should be considered as a tool to decrease rising STD and HIV rates among MSM who use the Internet to meet sexual partners.

Background: The purpose of this project was to determine the prevalence of asymptomatic sexually transmitted diseases (STDs) among men who have sex with men (MSM) in the Boston area who had been sexually active (oral and/or anal sex) with another male within the past year. Methods: Over a 1-month period (March 2007), asymptomatic MSM in care at a Boston community health center (n = 114) were screened for gonorrhea and chlamydia using the BD ProbeTec technique. Deidentified medical record data were analyzed and linked to prevalence monitoring results. Results: Eleven percent of the sample tested positive for one of the 2 STDs (gonorrhea or chlamydia) from at least one mucosal site. Individuals who were infected with an STD were considerably more likely to have a prior history of one or more STD infections when compared with those without an STD history (OR = 3.69; P <0.02). There were no significant differences observed in psychosocial and other behavioral risk factors between patients with or without an STD. Conclusions: Screening asymptomatic MSM using nucleic acid amplification tests (NAATs) revealed a substantial STD burden that might not have been diagnosed using traditional assays. These data are critical for the design of effective public health interventions for this population.

OBJECTIVES We sought to assess risk exposures, health care access, and screening rates for HIV and sexually transmitted infections (STIs) among men who have sex with men (MSM) in Massachusetts. METHODS We used a modified respondent-driven sampling method to collect data between March 2006 and May 2007. Overall, 126 MSM completed a survey. RESULTS Seventy percent of participants reported unprotected receptive anal intercourse with at least 1 nonmonogamous male partner; 50% reported having had a previous STI. Although 98% had visited a health care provider in the previous year, 39% had not been screened for STIs during the previous 2 years. Bisexual respondents were less likely to have told their health care providers that they engage in male-to-male sexual contact (OR = 4.66; P < .001), less likely to have been tested for STIs during in the previous 2 years (OR = 6.91; P < .001), and more likely to engage in insertive anal intercourse without a condom with an HIV-infected partner (OR = 5.04; P < .005) than were non-bisexual respondents. CONCLUSIONS Clinicians need to assess sexual risk-taking behaviors and more routinely screen for STIs among sexually active men regardless of disclosure of a history of having sex with men.

Objectives. We assessed Boston-area men who have sex with men (MSM) in terms of their knowledge of partner notification (PN)/partner counseling and referral services (PCRS) and intentions to use such services if exposed to/infected with a sexually transmitted disease (STD) or human immunodeficiency virus (HIV) in the future. Methods. The study used a convenience sample of STD clinic patients (n=48) and a modified respondent-driven sampling method (n=70) to reach a diverse sample of MSM (total sample n=118) in Massachusetts. Participants completed a one-on-one, open-ended, semistructured qualitative interview and quantitative survey. Results. Overall, white, HIV-infected MSM had the highest level of knowledge about PN activities. MSM who were unfamiliar with PN were disproportionately nonwhite and HIV-uninfected. Participants were more likely to notify past partners of HIV exposure than STD exposure. The preferred method of PN for the majority of MSM was direct person-to-person notification. Notably, nonwhite participants were more likely to endorse Massachusetts Department of Public Health PN services than white MSM, who preferred involvement of primary care providers. Conclusions. PN is an important public health strategy for treating and preventing STDs and HIV among at-risk populations, especially MSM who engage in sexual behavior with anonymous or otherwise non-notifiable sexual partners. Although many MSM had an understanding of the ethical desirability of informing exposed partners and recognized the value of preventative behaviors, they require further education to overcome barriers to PN as well as to gain knowledge of the various methods of both traditional and nontraditional notification, such as Internet PN.

Frequent use of websites and mobile telephone applications (apps) by men who have sex with men (MSM) to meet sexual partners, commonly referred to as “hookup” sites, make them ideal platforms for HIV prevention messaging. This Rhode Island case study demonstrated widespread use of hookup sites among MSM recently diagnosed with HIV. We present the advertising prices and corporate social responsibility (CSR) programs of the top five sites used by newly diagnosed HIV-positive MSM to meet sexual partners: Grindr, Adam4Adam, Manhunt, Scruff, and Craigslist. Craigslist offered universal free advertising. Scruff offered free online advertising to selected nonprofit organizations. Grindr and Manhunt offered reduced, but widely varying, pricing for nonprofit advertisers. More than half (60%, 26/43) of newly diagnosed MSM reported meeting sexual partners online in the 12 months prior to their diagnosis. Opportunities for public health agencies to promote HIV-related health messaging on these sites were limited. Partnering with hookup sites to reach high-risk MSM for HIV prevention and treatment messaging is an important public health opportunity for reducing disease transmission risks in Rhode Island and across the United States.

Background In Rhode Island, the Patient Protection and Affordable Care Act has led to over 95% of the states population being insured. We evaluated insurance coverage and barriers to insurance use among patients presenting for services at the Rhode Island sexually transmitted disease (STD) clinic. Methods We analyzed factors associated with insurance coverage and utilization among patients presenting for STD services between July and December 2015. Results A total of 692 patients had insurance information available; of those, 40% were uninsured. Patients without insurance were more likely than those with insurance to be nonwhite (50% among uninsured, compared with 40% among insured; P = 0.014) and Hispanic or Latino/a (25%, compared with 16%; P = 0.006), and less likely to be men who have sex with men (27%, compared with 39%; P = 0.001). Of those with health insurance, 26% obtained coverage as a result of the Affordable Care Act, and 56% of those were previously uninsured. Among uninsured individuals, barriers to obtaining health insurance included cost and unemployment. Among those with insurance, 43% reported willingness to use insurance for STD services. Barriers to insurance use included concerns about anonymity and out-of-pocket costs. Conclusions Despite expanded insurance access, many individuals presenting to the Rhode Island STD Clinic were uninsured. Among those who were insured, significant barriers still existed to using insurance. STD clinics continue to play an important role in providing safety-net STD services in states with low uninsured rates. Both public and private insurers are needed to address financial barriers and optimize payment structures for services.

Background Partner notification services (PNS) are highly effective in reducing transmission of sexually transmitted diseases (STDs). We assessed outcomes of PNS before and after integration of an on-site disease intervention specialist (DIS) at a publicly-funded STD clinic. Methods From August 2014 to December 2015, patients testing positive for infectious syphilis or gonorrhea at the Rhode Island STD Clinic were referred to on-site DIS for partner notification. Data on PNS outcomes were reviewed for eight months before integration of DIS at the clinic and compared to eight months after. Results Of the 145 index patients referred for PNS during the study period (n = 58 before DIS integration, n = 87 after), 86% were interviewed. DIS integration resulted in a significantly greater proportion of index patients interviewed overall (92% versus 76%, p<0.01), on the day of diagnosis (85% versus 61%; p<0.01), and in person at the STD clinic (64% versus 11%; p<0.01). However, there was no significant difference in number of sexual partners named or treated. Conclusions Integrating DIS at a publicly-funded STD clinic resulted in a greater number of index cases interviewed, a greater number interviewed in person, and a greater number interviewed on the day of diagnosis. Challenges remain in identifying and engaging partners for treatment.

BackgroundPartner notification services (PNS) are recommended by the Centers for Disease Control and Prevention as a public health intervention for addressing the spread of HIV and other sexually transmitted diseases (STDs). Barriers and facilitators to the partner notification process from a public health perspective have not been well described.MethodsIn 2015, a coalition of New England public health STD directors and investigators formed to address the increasing STD prevalence across the region (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont) and to promote communication between state STD programs. To evaluate barriers and facilitators of PNS programs, a survey was administered to representatives from each state to describe PNS processes and approaches.ResultsOf the six PNS programs, Connecticut, Maine, Massachusetts, Vermont, and New Hampshire had combined HIV and STD PNS programs; Rhode Island’s programs were integrated but employed separate disease intervention specialists (DIS). All states performed PNS for HIV and syphilis. Maine, New Hampshire and Vermont performed services for all gonorrhea cases. Rhode Island, Connecticut, and Massachusetts performed limited partner notification for gonorrhea due to lack of resources. None of the six states routinely provided services for chlamydia, though Maine and Vermont did so for high-priority populations such as HIV co-infected or pregnant individuals. Across all programs, clients received risk reduction counseling and general STD education as a component of PNS, in addition to referrals for HIV/STD care at locations ranging from Planned Parenthood to community- or hospital-based clinics. Notable barriers to successful partner notification across all states included anonymous partners and index cases who did not feel comfortable sharing partners’ names with DIS. Other common barriers included insufficient staff, inability of DIS to identify and contact partners, and index cases declining to speak with DIS staff.ConclusionsIn New England, state health departments use different strategies to implement PNS programs and referral to STD care. Despite this, similar challenges exist across settings, including difficulty with anonymous partners and limited state resources.
