Increased Life Expectancy in New York City, 2001-2010: An Exploration by Cause of Death and Demographic Characteristics.

OBJECTIVE: New York City's (NYC's) life expectancy gains have been greater than those seen nationally. We examined life-expectancy changes over the past decade in selected NYC subpopulations and explored which age groups and causes of death contributed most to the increases. METHODS: We calculated life expectancy with 95% confidence intervals (CIs) for 2001-2010 by sex and race/ethnicity. Life expectancy was decomposed by age group and cause of death. Logistic regressions were conducted to reinforce the results from decomposition by controlling confounders. RESULTS: Overall, NYC residents' life expectancy at birth increased from 77.9 years (95% CI, 77.8-78.0) in 2001 to 80.9 years (95% CI, 80.8-81.0) in 2010. Decreases in deaths from heart disease, cancer, and HIV disease accounted for 50%, 16%, and 11%, respectively, of the gains. Decreased mortality in older age groups (≥65 years) accounted for 45.6% of the overall change. CONCLUSIONS: Life expectancy increased for both sexes, across all racial/ethnic groups, and for both the US-born and the foreign-born. Disparities in life expectancy decreased as overall life expectancy increased. Decreased mortality among older adults and from heart disease, cancer, and HIV infection accounted for most of the increases.

Evaluating the Use of an Electronic Death Registration System for Mortality Surveillance During and After Hurricane Sandy: New York City, 2012.

OBJECTIVES: We evaluated the use of New York City's (NYC's) electronic death registration system (EDRS) to conduct mortality surveillance during and after Hurricane Sandy. METHODS: We used Centers for Disease Control and Prevention guidelines for surveillance system evaluation to gather evidence on usefulness, flexibility, stability, timeliness, and quality. We assessed system components, interviewed NYC Health Department staff, and analyzed 2010 to 2012 death records. RESULTS: Despite widespread disruptions, NYC's EDRS was stable and collected timely mortality data that were adapted to provide storm surveillance with minimal additional resources. Direct-injury fatalities and trends in excess all-cause mortality were rapidly identified, providing useful information for response; however, the time and burden of establishing reports, adapting the system, and identifying indirect deaths limited surveillance. CONCLUSIONS: The NYC Health Department successfully adapted its EDRS for near real-time disaster-related mortality surveillance. Retrospective assessment of deaths, advanced methods for case identification and analysis, standardized reports, and system enhancements will further improve surveillance. Local, state, and federal partners would benefit from partnering with vital records to develop EDRSs for surveillance and to promote ongoing evaluation.

Barriers to HIV testing among HIV/AIDS concurrently diagnosed persons in New York City.

OBJECTIVES: To assess barriers to human immunodeficiency virus (HIV) testing, health care contacts history, and HIV testing history among patients diagnosed concurrently with HIV and acquired immunodeficiency syndrome (AIDS). METHODS: We surveyed patients concurrently diagnosed with HIV/AIDS who had participated in the partner notification program of the New York City Department of Health and Mental Hygiene, between January 2008 and December 2008. RESULTS: The most common reason interviewees volunteered for delaying testing (64%) was that they did not believe they were at risk for HIV. When read a list of potential barriers, 69% of interviewees replied affirmatively that they did not test for HIV because they did not believe they were at risk, and 52% replied affirmatively that they did not test because they thought their behaviors kept them safe from getting HIV. Half of all interviewees reported having insurance during part or all of the year before they were diagnosed with HIV/AIDS, and 70% had at least 1 health care visit in the year before they were diagnosed with HIV/AIDS. CONCLUSIONS: A lack of perception of risk was the most common reason for not testing for HIV sooner among these concurrently diagnosed patients. The majority of these patients were accessing medical care, indicating that this population could have benefited from routine HIV testing.

Unprotected anal intercourse and sexually transmitted diseases in high-risk heterosexual women.

OBJECTIVES: We examined the association between unprotected anal intercourse and sexually transmitted diseases (STDs) among heterosexual women. METHODS: In 2006 through 2007, women were recruited from high-risk areas in New York City through respondent-driven sampling as part of the National HIV Behavioral Surveillance study. We used multiple logistic regression to determine the relationship between unprotected anal intercourse and HIV infection and past-year STD diagnosis. RESULTS: Of the 436 women studied, 38% had unprotected anal intercourse in the past year. Unprotected anal intercourse was more likely among those who were aged 30 to 39 years, were homeless, were frequent drug or binge alcohol users, had an incarcerated sexual partner, had sexual partners with whom they exchanged sex for money or drugs, or had more than 5 sexual partners in the past year. In the logistic regression, women who had unprotected anal intercourse were 2.6 times as likely as women who had only unprotected vaginal intercourse and 4.2 times as likely as women who had neither unprotected anal nor unprotected vaginal intercourse to report an STD diagnosis. We found no significant association between unprotected anal intercourse and HIV infection. CONCLUSIONS: Increased screening for history of unprotected anal intercourse and, for those who report recent unprotected anal intercourse, counseling and testing for HIV and STDs would likely reduce STD infections.

The effect of HIV field-based testing on the proportion of notified partners who test for HIV in New York City.

HIV partner services can effectively reach populations with high HIV prevalence. However, located and notified sex and needle-sharing partners of persons infected with HIV often fail to test. Field testing may increase the proportion of notified partners who test for HIV. In 2008, New York City's health department incorporated field testing into partner services. After the introduction of field testing, the proportion of notified partners who tested for HIV rose from 52% to 76% (P<.001). HIV prevalence fell slightly among notified partners who accepted testing (12% to 9%, P=.82), but we identified more than double the number of new positives (11 vs 25). All positive and 97% of negative results were received by the person tested.

NYC condom use and satisfaction and demand for alternative condom products in New York City sexually transmitted disease clinics.

In 2007, via a high-profile media campaign, the New York City Department of Health and Mental Hygiene (NYC DOHMH) introduced the "NYC Condom," the first specially packaged condom unique to a municipality. We conducted a survey to measure NYC Condom awareness of and experience with NYC Condoms and demand for alternative male condoms to be distributed by the DOHMH. Trained interviewers administered short, in-person surveys at five DOHMH-operated sexually transmitted disease (STD) clinics in Spring 2008. We systematically sampled eligible patients: NYC residents aged ≥18 years waiting to see a physician. We approached 539; 532 agreed to be screened (98.7% response rate); 462 completed the survey and provided NYC zip codes. Most respondents were male (56%), non-Hispanic black (64%), aged 18-24 years (43%) or 25-44 years (45%), employed (65%), and had a high school degree/general equivalency diploma or less (53%). Of those surveyed, 86% were aware of the NYC Condom, and 81% of those who obtained the condoms used them. NYC Condom users were more likely to have four or more sexual partners in the past 12 months (adjusted odds ratio [AOR] = 2.0, 95% confidence interval [CI] = 1.0-3.8), use condoms frequently (AOR = 2.1, 95% CI = 1.3-3.6), and name an alternative condom for distribution (AOR = 2.2, 95% CI = 1.3-3.9). The most frequently requested condom types respondents wanted DOHMH to provide were larger size (28%), ultra thin/extra sensitive (21%), and extra strength (16%). We found high rates of NYC Condom use. NYC Condom users reported more sexual partners than others, suggesting the condom initiative successfully reached higher-risk persons within the STD clinic population. Study results document the condom social marketing campaign's success.

Evaluation of HIV incidence surveillance in New York City, 2006.

In 2005, the New York City (NYC) Department of Health and Mental Hygiene implemented a standardized human immunodeficiency virus (HIV) incidence surveillance protocol based on the serologic testing algorithm for recent HIV seroconversion deployed nationwide by the Centers for Disease Control and Prevention (CDC). We evaluated four key attributes of NYC's HIV incidence surveillance system-simplicity, data quality, timeliness, and acceptability--using CDC's guidelines for surveillance system evaluation. The evaluation revealed that the system could potentially provide HIV incidence estimates stratified by borough and major demographic groups at about nine months after the period of interest. The system strengths include its relative simplicity and integration with routine HIV/acquired immunodeficiency syndrome surveillance. Weaknesses include lack of completeness of testing history information, a critical component of incidence estimation. Continued improvements in data completeness and timeliness will improve the currently available information to inform personnel who develop HIV-prevention programs and policy initiatives in NYC and nationally.

High HIV prevalence and diagnosis rates in New York City black men.

We sought to identify population and subpopulation disparities in rates of HIV diagnosis and prevalence among black males 13 years and older in New York City. We used population-based data from the New York City HIV/AIDS surveillance registry and US Census 2000 to calculate HIV prevalence in 2006 and HIV diagnosis rates in 2007. Black males were the largest demographic group of new HIV diagnoses (n = 1,161, 33%) and persons living with HIV/AIDS in New York City (n = 24,294, 29%) and had the highest diagnosis rates (1.7 per 1,000 population) and prevalence (3.7%). Prevalence and diagnosis rates among black males were higher in higher-poverty neighborhoods than in lower-poverty neighborhoods (p < 0.01). However, very high prevalence (19.3%) was found among black males in three adjacent Manhattan neighborhoods with relatively low poverty rates, and where overall diagnosis rates among black males (7.4 per 1,000) and proportions attributable to men who have sex with men (60.0%) were high. HIV-related disparities exist not only between black males and other groups but also within black males. Success addressing the citywide HIV epidemic will be linked to success in the various portions of this highly affected, heterogeneous population.

Excess mortality among injection drug users with AIDS, New York City (1999-2004).

We calculated proportions and trends in contributing causes of death among persons with AIDS (PWA) and a history of injection drug use (IDU) in New York City and compared the proportions with those among PWA with a transmission risk of high-risk heterosexual sex (HRH) and men who have sex with men (MSM). We included all 10,575 injection drug user, HRH, and MSM residents aged 13+ years with AIDS reported by September 30, 2006 , who died from 1999 through 2004. Accidental drug overdose was the most frequent contributing cause of death among IDUs (20.5%). Overdose prevention initiatives may greatly and immediately reduce deaths among PWA.

Provider and client acceptance of a health department enhanced approach to improve HIV partner notification in New York City.

OBJECTIVE: To assess provider and client acceptance of health department-delivered HIV partner services (PS) delivered in clinical and community settings. METHODS: In 2006, New York city (NYC) formed the HIV field services unit (FSU), staffed with experienced sexually transmitted disease intervention specialists (DIS). DIS were stationed at 8 large hospitals to assist clinical providers and their HIV-positive patients with PS in areas with high rates of delayed HIV diagnoses and HIV-related mortality. We surveyed providers (self-administered questionnaire) and clients (staff-administered) to examine provider and patients as well as patients' HIV-exposed partners' acceptance of and concerns regarding PS. RESULTS: Response rates were as follows: 63% (132/211) providers; 90% (492/544) patients who accepted PS; 73% (16/22) patients who declined PS; 83% (139/168) partners who received notification; and 81% (25/31) partners who declined notification. Most providers felt the DIS focus and expert skills in PS was beneficial to providers (87%) and clients (89%). Most patients (91%) had a positive or neutral attitude about the health department-delivered PS. Most providers reported no disadvantage to DIS providing PS (69%); their most commonly cited (24%) concern was potential patient confusion about the roles of providers versus DIS. Patients' most common concerns were the intrusive nature of the interviews and the length of the interview (50/492, 20%). The partners wanted to know who named them (32/139, 23%). CONCLUSIONS: Health department-delivered PS by DIS in clinical and community settings was acceptable to providers, HIV-infected patients, and HIV-exposed partners. Overall, our survey showed strong provider and client support for this approach.

Comparing HIV partner notification effectiveness between blacks and Hispanics in New York City.

Between July 2006 and November 2007, a total of 894 blacks and 491 Hispanics were interviewed to assess partner notification services. Fewer Hispanics needed to be interviewed to identify 1 newly diagnosed partner as compared with blacks (24 vs. 60, P < 0.01), but number needed to be interviewed was similar for identifying partners with any HIV infection.

The NYC Condom: use and acceptability of New York City's branded condom.

We assessed awareness and experience with the NYC Condom via surveys at 7 public events targeting priority condom distribution populations during 2007. Most respondents (76%) were aware of NYC Condoms. Of those that had obtained them, 69% had used them. Most (80%) wanted alternative condoms offered for free: 22% wanted ultra-thin, 18% extra-strength, and 14% larger-size. Six months after the NYC Condom launch, we found high levels of awareness and use. Because many wanted alternative condoms, the Department of Health and Mental Hygiene began distributing the 3 most-requested alternatives.

Comparing the National Death Index and the Social Security Administration's Death Master File to ascertain death in HIV surveillance.

OBJECTIVES: New York City (NYC) maintains a population-based registry of people with human immunodeficiency virus (HIV) infection to monitor the epidemic and inform resource allocation. We evaluated record linkages with the National Death Index (NDI) and the Social Security Administration's Death Master File (SSDMF) to find deaths occurring from 2000 through 2004. METHODS: We linked records from 32,837 people reported with HIV and not previously known to be dead with deaths reported in the NDI and the SSDMF. We calculated the kappa statistic to assess agreement between data sources. We performed subgroup analyses to assess differences within demographic and transmission risk subpopulations. We quantified the benefit of linkages with each data source beyond prior death ascertainment from local vital statistics data. RESULTS: We discovered 1,926 (5.87%) deaths, which reduced the HIV prevalence estimate in NYC by 2.03%, from 1.19% to 1.16%. Of these, 458 (23.78%) were identified only from NDI, and 305 (15.84%) only from SSDMF. Agreement in ascertainment between sources was substantial (kappa = [K] 0.74, 95% confidence interval [CI] 0.72, 0.76); agreement was lower among Hispanic people (K = 0.65, 95% CI 0.62, 0.69) and people born outside the U.S. (K = 0.60, 95% CI 0.52, 0.68). We identified an additional 13.62% of deaths to people reported with HIV in NYC; white people and men who have sex with men were disproportionately likely to be underascertained without these linkages (p < 0.0001). CONCLUSION: Record linkages with national databases are essential for accurate prevalence estimates from disease registries, and the SSDMF is an inexpensive means to supplement linkages with the NDI to maximize death ascertainment.

The free condom initiative: promoting condom availability and use in New York City.

In 2005, the New York City Department of Health and Mental Hygiene (DOHMH) made free condoms available to organizations through a Web-based ordering system. In 2006, we interviewed managers and patrons about free condom availability, acquisition, and use in venues where people at high risk for human immunodeficiency virus congregate. DOHMH condom distribution increased from 5.8 million in 2004 to 17.3 million in 2006. Overall, managers reported making condoms available at 76% (309/409) of high-priority venues, but only at 40% of gay bars. Among patrons who saw free condoms, 80% (280/351) reported taking them; 73% (205/280) of those who reported taking them also reported using them. A simple, Web-based ordering system dramatically increased condom distribution. In the venues we sampled, the majority of patrons acquired and used free condoms when available and visible, suggesting that increasing free condom availability may increase use. Special efforts are needed to ensure availability at gay bars.

An outbreak of concurrent echovirus 30 and coxsackievirus A1 infections associated with sea swimming among a group of travelers to Mexico.

BACKGROUND: Enteroviruses are shed in human stool and can cause a wide spectrum of illness. They are the leading cause of aseptic meningitis. METHODS: In 2004, the Connecticut Department of Public Health investigated a meningitis cluster among persons returning from a school-organized trip to Mexico. RESULTS: Among 29 travelers (25 teenagers and 4 adult chaperones), 21 became acutely ill. Viral culture and nucleic acid amplification testing of stool (n=27) and cerebrospinal fluid (n=4) specimens identified enteroviral infection in 20 of 28 travelers from whom any specimen was obtained; 4 had echovirus 30 only, 11 had coxsackievirus (CV) A1 only, 4 had both echovirus 30 and CVA1, and 1 had CVA5 only. Illness onset dates were tightly clustered 4 days after a prolonged swim in the Gulf of Mexico. Time spent swimming was significantly associated with the odds of enteroviral infection (univariate odds ratio for each additional hour swimming, 14.3; 95% confidence interval, 1.3-154.3). Headache, fever, vomiting, and nausea occurred more frequently among the echovirus 30-infected travelers than among the uninfected control subjects (P< .05). The most frequent symptoms among travelers infected with only CVA1 identified were nausea and diarrhea (36% each), but neither was significantly associated with CVA1 infection; 5 patients with CVA1 infection were asymptomatic. CONCLUSIONS: We identified multiple enteroviruses among the travelers. Clustered illness onsets suggest point-source exposure, which likely was a sea swim in sewage-contaminated seawater. Novel molecular amplification and sequencing methodologies were required to recognize the rarely identified CVA1, but it is ambiguous whether CVA1 infection caused illness. Travelers should be aware of risks associated with swimming in natural waters when visiting areas where there is limited sewage treatment.

Human immunodeficiency virus partner elicitation and notification in new york city: public health does it better.

BACKGROUND: Partner notification (PN) is an effective strategy to identify undiagnosed human immunodeficiency virus (HIV) infections and to likely reduce HIV transmission. Whereas published literature has documented the benefits of provider referral for HIV PN, determination of the optimal provider--health department staff or community clinician--has not been previously studied. This study examined whether PN conducted by New York City (NYC) Disease Intervention Specialists (DIS) is more successful than PN conducted by community clinicians. METHODS: PN results overall and by index case-patient characteristics were compared for new HIV cases diagnosed in public sexually transmitted disease (STD) clinics versus those diagnosed in non-STD facilities. RESULTS: In NYC in 2004, 206 new HIV cases were diagnosed in STD clinics and 3460 in non-STD facilities. STD DIS personnel elicited 4 times as many partners per case diagnosed (0.87 vs. 0.22, P <0.01). Index case-patient characteristics differed between STD clinics and non-STD facilities, but STD DIS elicited more partners within all demographic and risk subgroups. Excluding partners previously HIV+, the proportion of partners notified was 70.9% for partners elicited by STD DIS and 48.3% for partners elicited by community clinicians (P <0.01). Among tested partners with previously unknown or negative status, the proportion of new HIV diagnoses was similar between those elicited by DIS and community clinicians (27.0% vs. 22.2%, P = 0.56). CONCLUSIONS: NYC STD DIS appear to be more effective than community clinicians at both partner elicitation and notification. NYC has stationed DIS at large healthcare facilities to assist community clinicians with the PN process.

Why don't physicians test for HIV? A review of the US literature.

OBJECTIVE: In its 2006 HIV testing guidelines, the Centers for Disease Control and Prevention (CDC) recommended routine testing in all US medical settings. Given that many physicians do not routinely test for HIV, the objective of this study was to summarize our current understanding of why US physicians do not offer HIV testing. DESIGN: A comprehensive review of the published and unpublished literature on HIV testing barriers was conducted. METHODS: A literature search was conducted in Pubmed using defined search terms. Other sources included Google, recent conference abstracts, and experts in the field. Studies were divided into three categories: prenatal; emergency department; and other medical settings. These categories were chosen because of differences in physician training, practice environment, and patient populations. Barriers identified in these sources were summarized separately for the three practice settings and compared. RESULTS: Forty-one barriers were identified from 17 reports. Twenty-four barriers were named in the prenatal setting, 20 in the emergency department setting, and 23 in other medical settings. Eight barriers were identified in all three categories: insufficient time; burdensome consent process; lack of knowledge/training; lack of patient acceptance; pretest counselling requirements; competing priorities; and inadequate reimbursement. CONCLUSION: US physicians experience many policy-based, logistical, and educational barriers to HIV testing. Although some barriers are exclusive to the practice setting studied, substantial overlap was found across practice settings. Some or all of these barriers must be addressed before the CDC recommendation for routine HIV testing can be realized in all US medical settings.

Perinatal hepatitis B transmission and vaccination timing in a managed care cohort: assessment of the temporary delay in newborn hepatitis B vaccination due to thimerosal content.

BACKGROUND: From July to September 1999, due to a concern of toxicity from exposure to thimerosal-containing vaccines, the American Academy of Pediatrics and U.S. Public Health Service temporarily recommended delaying the administration of first dose of hepatitis B vaccine until the age of 2-6 months for infants born to hepatitis B surface antigen negative mothers. Our objectives were to determine whether the recommendation affected the rate of perinatal hepatitis B infection in a multistate managed care population; to describe neonatal and early childhood cases of hepatitis B infection and to evaluate a possible role of the recommendation; and to assess the timeliness, with respect to the U.S. childhood immunization schedule, of vaccinations during the first 2 years of life. METHODS: We identified 3 cohorts of infants born before (July 1998 to June 1999), during (July 1999 to September 1999) and after (October 1999 to September 2000) the recommendation period. We used automated claims data to identify possible neonatal and early childhood hepatitis B cases using specific ICD-9 diagnosis and CPT procedure codes and validated cases through medical record review. Using Health Plan Employer Data and Information Set (HEDIS) data, we calculated vaccination coverage for the first dose of hepatitis B vaccine at 3-month intervals from January 1999 to September 2000. RESULTS: The eligible populations in the "before," "during" and "after" cohorts were 29,347, 7791 and 29,215 infants, respectively. Of 41 possible hepatitis B cases identified in the 3 cohorts, we confirmed 1 case in the after cohort with medical record review. Despite receiving the first dose of hepatitis B vaccine and hepatitis B immunoglobulin within 12-24 hours of birth, the infant was diagnosed with laboratory-confirmed chronic hepatitis B at age of 9 months. An analysis of HEDIS data showed that vaccination coverage for the first dose of hepatitis B vaccine was 98% (January to March 1999) and 96% (April to June 1999) for the "before" cohort and 66% for the "during" cohort. For the "after" cohort the coverage was 72% (October to December 1999), 83% (January to March 2000), 91% (April to June 2000) and 95% (July to September 2000). CONCLUSIONS: This study did not identify any perinatal hepatitis B transmission among health plan enrollees associated with the 1999 recommendation. The recommendation did result in a delay of hepatitis B birth dose in the "during" cohort as intended for infants born to hepatitis B surface antigen negative mothers. Six months after the recommendation was rescinded there was still a delay in the timing of first dose of hepatitis B vaccine, but the timing had returned to the prerecommendation level after 9-12 months.

Outbreak bias in illness reporting and case confirmation in ciguatera fish poisoning surveillance in south Florida.

OBJECTIVE: Ciguatera fish poisoning is a potentially life-threatening disease caused by eating coral reef fish contaminated with ciguatoxins and is the most common marine poisoning. However, existing surveillance systems capture few cases. To improve regional ciguatera surveillance in South Florida, this study compared ciguatera illnesses in the Florida Poison Information Center-Miami (FPICM) call database to ciguatera cases in the Florida Department of Health (FDOH) disease surveillance systems. METHODS: Univariate and multivariate logistic regression were used to identify predictors of when FPICM reported ciguatera illnesses to FDOH and whether FDOH confirmed reported ciguatera cases. RESULTS: FPICM staff preferentially reported ciguatera illnesses that were of shorter duration (adjusted odds ratio [AOR] = 0.84 per additional illness day; 95% confidence interval [CI] 0.74, 0.97); outbreak-associated (AOR = 7.0; 95% CI 2.5, 19.5); and clinically more severe (AOR = 21.6; 95% CI 2.3, 198.5). Among ciguatera illnesses reported to FDOH, outbreak-associated illnesses were more likely than single, sporadic illnesses to become confirmed surveillance cases (crude OR = 11.1; 95% CI 2.0, 62.5). CONCLUSIONS: The over-representation of outbreak-associated ciguatera cases underestimates the true contribution of sporadic illnesses to ciguatera disease burden. This bias should be considered when evaluating surveillance systems that include both outbreak-associated and sporadic illness reports.
