ABSTRACT: In May 2001, The New York City Department of Health and Mental Hygiene was informed of a cluster of 4 patients treated at an outpatient gastroenterology center who developed acute hepatitis C virus infection. An investigation identified a total of 12 clinic-associated hepatitis C virus transmissions and the outbreak and was traced to unsafe handling of multidose anesthetic vials and possible re-use of contaminated needles. This report typifies the types of outbreaks that continue to occur despite safe injection guidelines.

ABSTRACT: To describe New York City (NYC) assisted living facility (ALF) characteristics, services offered, and infection control practices and to identify infection control barriers and unmet needs.
Cross-sectional.
ALFs licensed or applying to be licensed in NYC.
Seventy ALFs; 70 of 77 eligible facilities participated (91% participation rate).
Telephone interview questions assessed ALF characteristics, services offered, and infection control practices, including glucometry practices.
ALFs provided a broad range of services, such as vaccination (90%), assistance with taking medication (75%), bathing and showering (33%), and blood glucose monitoring (90%). Ninety percent of the facilities had nurses on site (directly employed or through a contract agency). Five facilities reported that residents sometimes shared glucometers, and one reported that fingerstick devices were sometimes shared. The majority of facilities wanted educational materials for staff (83%) and residents (77%) on topics including influenza, respiratory illness, norovirus, standard precautions, and general infection control. ALFs had a range of sick leave policies and infection control training requirements. Eighty-nine percent of the facilities reported having designated staff responsible for infection control, although 50% had nonclinical job titles.
NYC ALFs were varied in terms of nursing services offered, characteristics, and residents' needs; therefore, public health agencies may need to be flexible in their assistance. Public health agencies should consider strengthening relationships with ALFs to identify unmet needs and gaps in services.

ABSTRACT: Chronic hepatitis B virus (HBV) infection is a preventable cause of liver failure, cirrhosis, and liver cancer; estimated chronic HBV infection prevalence is 0.3-0.5% in the U.S.A. Prevalence in New York City (NYC) is likely higher because foreign-born persons, who represent 36% of NYC's population versus 11% nationwide, bear a disproportionate burden of chronic HBV infection. However, because no comprehensive, population-based survey of chronic HBV infection has been conducted in NYC, a reliable prevalence estimate is unavailable. We used two approaches to estimate chronic HBV infection prevalence in NYC: (1) a census-based estimate, combining local and national prevalence data for specific populations, and (2) a surveillance-based estimate, using data from NYC's Department of Health and Mental Hygiene Hepatitis B Surveillance Registry and adjusting for out-migration and deaths. Results from both the census-based estimate and the surveillance-based estimate were similar, with an estimated prevalence of chronic HBV in NYC of 1.2%. This estimate is two to four times the estimated prevalence for the U.S.A. as a whole. According to the census-based estimate, >93% of all cases in NYC are among persons who are foreign-born, and approximately half of those are among persons born in China. These findings underscore the importance of local data for tailoring programmatic efforts to specific foreign-born populations in NYC. In particular, Chinese-language programs and health education materials are critical. Reliable estimates are important for policymakers in local jurisdictions to better understand their own population's needs and can help target primary care services, prevention materials, and education.

ABSTRACT: Hepatitis C virus (HCV) is the leading cause of chronic liver disease in the United States. Accurate hepatitis C prevalence estimates are important to guide local public health programs but are usually unavailable to local health jurisdictions. National surveys may not reflect local variation, a particular challenge for urban settings with disproportionately large numbers of residents in high-risk population groups. In 2004, the New York City Department of Health and Mental Hygiene conducted the NYC Health and Nutrition Examination Survey, a population-based household survey of non-institutionalized NYC residents ages 20 and older. Study participants were interviewed and blood specimens were tested for antibody to HCV (anti-HCV); positive participants were re-contacted to ascertain awareness of infection and to provide service referrals. Of 1,786 participants with valid anti-HCV results, 35 were positive for anti-HCV, for a weighted prevalence of 2.2% (95% confidence interval [CI] 1.5% to 3.3%). Anti-HCV prevalence was high among participants with a lifetime history of injection drug use (64.5%, 95% CI 39.2% to 83.7%) or a lifetime history of incarceration as an adult (8.4%, 95% CI 4.3% to 15.7%). There was a strong correlation with age; among participants born between 1945 and 1954, the anti-HCV prevalence was 5.8% (95% CI 3.3% to 10.0%). Of anti-HCV positive participants contacted (51%), 28% (n = 5) first learned of their HCV status from this survey. Continued efforts to prevent new infections in known risk behavior groups are essential, along with expansion of HCV screening and activities to prevent disease progression in people with chronic HCV.

ABSTRACT: To determine whether hepatitis B virus (HBV) transmission occurred among patients visiting a physician's office and to evaluate potential transmission mechanisms.
Serologic survey, retrospective cohort study, and observation of infection control practices.
Private medical office.
Those visiting the office between March 1 and December 26, 2001.
We identified 38 patients with acute HBV infection occurring between February 2000 and February 2002. The cohort study, limited to the 10 months before outbreak detection, included 91 patients with serologic test results and available charts representing 18 case-patients and 73 susceptible patients. Overall, 67 patients (74%) received at least one injection during the observation period. Case-patients received a median of 14 injections (range, 2-25) versus 2 injections (range, 0-17) for susceptible patients (P < .001). Acute infections occurred among 18 (27%) of 67 who received at least one injection versus none of 24 who received no injections (RR, 13.6; CI95, 2.4-undefined). Risk of infection increased 5.2-fold (CI95, 0.6-47.3) for those with 3 to 6 injections and 20.0-fold (CI95, 2.8-143.5) for those with more than 6 injections. Typically, injections consisted of doses of atropine, dexamethasone, vitamin B12, or a combination of these mixed in one syringe. HBV DNA genetic sequences of 24 patients with acute infection and 4 patients with chronic infection were identical in the 1,500-bp region examined. Medical staff were seronegative for HBV infection markers. The same surface was used for storing multidose vials, preparing injections, and dismantling used injection equipment.
Administration of unnecessary injections combined with failure to separate clean from contaminated areas and follow safe injection practices likely resulted in patient-to-patient HBV transmission in a private physician's office.

ABSTRACT: After the 2001 World Trade Center disaster, the New York City Department of Health was under heightened alert for bioterrorist attacks in the city. An emergency department (ED) syndromic surveillance system was implemented with the assistance of the Centers for Disease Control and Prevention to ensure early recognition of an increase or clustering of disease syndromes that might represent a disease outbreak, whether natural or intentional. The surveillance system was based on data collected 7 days a week at area EDs. Data collected were translated into syndromes, entered into an electronic database, and analyzed for aberrations in space and time within 24 hours. From September 14-27, personnel were stationed at 15 EDs on a 24-hour basis (first staffing period); from September 29-October 12, due to resource limitations, personnel were stationed at 12 EDs on an 18-hour basis (second staffing period). A standardized form was used to obtain demographic information and classify each patient visit into 12 syndrome categories. Seven of these represented early manifestations of bioterrorist agents. Data transfer and analysis for time and space clustering (alarms) by syndrome and age occurred daily. Retrospective analyses examined syndrome trends, differences in reporting between staffing periods, and the staff's experience during the project. A total of 67,536 reports were received. The system captured 83.9% of patient visits during the first staffing period, and 60.8% during the second staffing period (P < 0.01). Five syndromes each accounted for more than 1% of visits: trauma, asthma, gastrointestinal illness, upper/lower respiratory infection with fever, and anxiety. Citywide temporal alarms occurred eight times for three of the major bioterrorism-related syndromes. Spatial clustering alarms occurred 16 times by hospital location and 9 times by ZIP code for the same three syndromes. No outbreaks were detected. On-site staffing to facilitate data collection and entry, supported by daily analysis of ED visits, is a feasible short-term approach to syndromic surveillance during high-profile events. The resources required to operate such a system, however, cannot be sustained for the long term. This system was changed to an electronic-based ED syndromic system using triage log data that remains in operation.

ABSTRACT: This project sought to describe unmet needs among patients reported with hepatitis C in New York City.
From the New York City Health Department's hepatitis C surveillance database, we randomly selected patients whose positive hepatitis C test was in April or May 2005. In 2006, we interviewed patients by telephone and collected information from their clinicians or by medical record review.
New York City.
We interviewed 180 of the 387 eligible patients and collected information from clinicians for 145 of the 180 patients.
These included whether patients had understood their clinicians' explanation of their hepatitis C diagnosis, if they had been counseled about not drinking alcohol, information about support group attendance, vaccination against hepatitis A and B, health status, treatment, and other factors.
Of the 180 patients, 7% stated that they had not understood their clinicians' explanation of their hepatitis C diagnosis, and 26% said that they had not been counseled about avoiding alcohol. Among the 90% of patients who had not attended a hepatitis support group, 31% were interested in attending. Among the 145 patients with information from clinicians, at least 28% were susceptible to hepatitis A and 18% to hepatitis B.
This hepatitis C surveillance project, with information from patients and clinicians, illustrates a valuable use of a chronic hepatitis C surveillance system. The patients described here had several unmet needs, including hepatitis A and B vaccination, basic information about the virus, support groups, and counseling about preventing further liver damage and preventing transmission to others. Relatively simple and affordable health department activities can address these needs, improving quality of life and decreasing the likelihood of liver disease progression.
