Evaluation of a health information exchange system for microcephaly case-finding - New York City, 2013-2015.

BACKGROUND: Birth defects surveillance in the United States is conducted principally by review of routine but lagged reporting to statewide congenital malformations registries of diagnoses by hospitals or other health care providers, a process that is not designed to rapidly detect changes in prevalence. Health information exchange (HIE) systems are well suited for rapid surveillance, but information is limited about their effectiveness at detecting birth defects. We evaluated HIE data to detect microcephaly diagnosed at birth during January 1, 2013-December 31, 2015 before known introduction of Zika virus in North America. METHODS: Data from an HIE system were queried for microcephaly diagnostic codes on day of birth or during the first two days after birth at three Bronx hospitals for births to New York City resident mothers. Suspected cases identified by HIE data were compared with microcephaly cases that had been identified through direct inquiry of hospital records and confirmed by chart abstraction in a previous study of the same cohort. RESULTS: Of 16,910 live births, 43 suspected microcephaly cases were identified through an HIE system compared to 67 confirmed cases that had been identified as part of the prior study. A total of 39 confirmed cases were found by both studies (sensitivity = 58.21%, 95% CI: 45.52-70.15%; positive predictive value = 90.70%, 95% CI: 77.86-97.41%; negative predictive value = 99.83%, 95% CI: 99.76-99.89% for HIE data). CONCLUSION: Despite limitations, HIE systems could be used for rapid newborn microcephaly surveillance, especially in the many jurisdictions where more labor-intensive approaches are not feasible. Future work is needed to improve electronic medical record documentation quality to improve sensitivity and reduce misclassification.

Experiences and sexual behaviors of HIV-infected MSM who acquired HIV in the context of crystal methamphetamine use.

The prevalence of crystal methamphetamine "meth" use among men who have sex with men (MSM) has been shown to be 20 times that of the general population, and it has been linked to increased sexual risk taking in MSM and others. Although previously seen as a "West Coast" phenomenon, clinical and other reports indicate that it is problematic among MSM regardless of geographic location. To assist in future intervention development, we interviewed 20 HIV-infected MSM who believe they seroconverted in the context of using crystal meth. Topics included factors related to continued and previous meth use, HIV risk behavior prior to and after HIV infection, and the consequences of sustained use. Generally, participants openly discussed the highly destructive effects of using crystal meth. Almost every (95%) participant spoke of chronic depression and anxiety following cycles of discontinued use, and participants often claimed an inability to enjoy activities that used to be pleasurable. Almost all (90%) respondents also reported that their social relationships were compromised by their crystal addictions. Many had lost friends, and in some cases, non-drug-using friends distanced themselves because of the addiction. A striking number of participants felt strongly that MSM sexual partner-meeting Web sites represented a major starting point for crystal-influenced sexual "hookups," and that they should likewise be a starting point for interventions. Corroborating previous research in this arena, this study exhibits support for a link between crystal meth use and high-risk sexual behavior among East Coast MSM. The study also draws attention to the need for associated mental health, functional and quality-of life impairments that seem to accompany continued use in individuals with HIV.

Acceptability of an internet-based partner notification system for sexually transmitted infection exposure among men who have sex with men.

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.

HIV and STD status among MSM and attitudes about Internet partner notification for STD exposure.

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 P's <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 P's <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.
