Introduction: Population-based disability prevalence estimates are limited for New York City (NYC). We examined the associa­tion of several health and health-related measures with disability among NYC resi­dents aged 20-64 years.Methods: We used information from 1,314 adults who participated in the 2013-2014 NYC Health and Nutrition Examination Sur­vey (HANES). We categorized survey partici­pants as having a disability if they reported a physical, mental, and/or emotional problem preventing work or if they reported difficulty walking without special equipment because of a health problem. We used log-binomial regression to quantify the association of each exposure with disability before and after adjustment for select covariates.Results: Overall, 12.4% of the study’s NYC residents aged 20-64 years had a disabil­ity. After adjustment, disability prevalence was significantly greater among those who reported having unmet health care needs (prevalence ratio [PR] = 1.75, 95% CI: 1.18-2.57) and those who reported fair/ poor general health (PR = 2.33, 95% CI: 1.68-3.24). The probability of disability was greater among NYC residents with arthritis (PR = 2.66, 95% CI: 1.85-3.98) and hy­pertension (PR = 1.48, 95% CI: 1.04-2.11) when compared with those without these conditions. Disability was also associated with depression (PR = 2.96, 95% CI: 2.06- 4.25), anxiety (PR = 2.89, 95% CI: 2.15- 3.88), and post-traumatic stress disorder (PR = 2.55, 95% CI: 1.66-3.91). Disability, however, was not associated with diabetes.Conclusion: Disability is more prevalent among those with unmet health care needs, fair/poor general health, arthritis, hyperten­sion, depression, anxiety, and PTSD in these NYC residents, aged 20-64 years. These findings have implications for NYC’s strate­gic planning initiatives, which can be better targeted to groups disproportionately affect­ed by disability.Ethn Dis. 2021;31(3):445- 452; doi:10.18865/ed.31.3.445

Purpose In this study we aim to estimate the change in metabolic syndrome (MetS) prevalence among New York City (NYC) adults between 2004 and 2013–2014 and identify key subgroups at risk. Methods We analyzed data from NYC Health and Nutrition Examination Survey. MetS was defined as having at least three of the following: abdominal obesity, low HDL, elevated triglycerides, glucose dysregulation, and elevated blood pressure. We calculated age-standardized MetS prevalence, change in prevalence over time, and prevalence ratios by gender and race/ethnicity groups. We also tested for additive interaction. Results In 2013–2014 MetS prevalence among NYC adults was 24.4% (95% CI, 21.4–27.6). Adults 65+ years and Asian adults had the highest prevalence (45.6% and 33.8%, respectively). Abdominal obesity was the most prevalent MetS component in 2004 and 2013–2014 (50.7% each time). Between 2004 and 2013–2014, MetS decreased by 18.2% (P = .04) among women. The decrease paralleled similar declines in elevated triglycerides and glucose dysregulation. In 2013–14, non-Latino Black women had higher risk of MetS than non-Latino Black men and non-Latino White adults. Conclusion Age and racial/ethnic disparities in MetS prevalence in NYC were persistent from 2004 to 2013–2014, with Asian adults and non-Latino Black women at particularly high risk.

Objectives Immigrant adults tend to have better health than native-born adults despite lower incomes, but the health advantage decreases with length of residence. To determine whether immigrant adults have a health advantage over US-born adults in New York City, we compared cardiovascular disease (CVD) risk factors among both groups. Methods Using data from the New York City Health and Nutrition Examination Survey 2013-2014, we assessed health insurance coverage, health behaviors, and health conditions, comparing adults ages ≥20 born in the 50 states or the District of Columbia (US-born) with adults born in a US territory or outside the United States (immigrants, following the National Health and Nutrition Examination Survey) and comparing US-born adults with (1) adults who immigrated recently (≤10 years) and (2) adults who immigrated earlier (>10 years). Results For immigrant adults, the mean time since arrival in the United States was 21.8 years. Immigrant adults were significantly more likely than US-born adults to lack health insurance (22% vs 12%), report fair or poor health (26% vs 17%), have hypertension (30% vs 23%), and have diabetes (20% vs 11%) but significantly less likely to smoke (18% vs 27%) (all P < .05). Comparable proportions of immigrant adults and US-born adults were overweight or obese (67% vs 63%) and reported CVD (both 7%). Immigrant adults who arrived recently were less likely than immigrant adults who arrived earlier to have diabetes or high cholesterol but did not differ overall from US-born adults. Conclusions Our findings may help guide prevention programs and policy efforts to ensure that immigrant adults remain healthy.

OBJECTIVE We explored associations between occupation and cardiovascular disease (CVD) risk behaviors including: attempted weight loss, physical activity, smoking, and restaurant meal and sugary beverage consumption. METHODS We used NYC Health and Nutrition Examination Survey 2013 to 2014 data, and coded free-text, occupational question responses using 2010 US Census Bureau Classification. CVD risk behaviors were compared across occupational categories, using regression to adjust for demographics. RESULTS There were health behavior differences across occupational categories. Construction/transportation/maintenance workers smoked more and were less likely than management to attempt weight loss, service workers were less likely to eat restaurant-prepared meals, sales/office workers were less likely to be physically active (all P

COVID-19 has had a disproportionate impact on those of Black and Hispanic race/ethnicity, older adults, and those with chronic conditions such as diabetes and heart disease 3 Higher-risk patients and practices could be selected for public health interventions and educational campaigns to decrease transmission, reduce inequities, and encourage patientswith symptoms to seek care early Neighborhood-level information can provide a helpful context for health risk factors and outcomes 7,9 Furthermore, linking EHRs to neighborhood-level resources could help providers connect patients in need to nearby food pantries, community centers, and housing assistance Previous comparisons with Behavioral Risk Factor Surveillance System (BRFSS) data and the Centers for Disease Control and Prevention's 500 Cities estimates (based on BRFSS) showed similar prevalence estimates with EHR-based data 10 It is noteworthy that Massachusetts has unusually high insurance coverage, with only 2 9% uninsured in 2019,11 which increases the generalizability of the MDPHnet system to the population as a whole Clearly there are challenges in linking data from different sources, including how to link and match data, how to protect privacy, and obtaining institutional review board permission 14 Yet such linkages could lead to a greater understanding of risk factors for disease, hospitalization and death, and the development of interventions for and targeted outreach to special populations

New York City Health and Nutrition Examination Survey (NYC HANES) was a population-based cross-sectional survey of NYC adults conducted twice, in 2004 and again in 2013–2014, to monitor the health of NYC adults 20 years or older. While blood pressure was measured in both surveys, an auscultatory mercury sphygmomanometer was used to measure blood pressure in clinics in 2004, and an oscillometric LifeSource UA-789AC monitor was used in homes in 2013–2014. To assess comparability of blood pressure results across both surveys, we undertook a randomized study comparing blood pressure (BP) readings by the two devices. Blood pressure measuring protocols followed the 2013 Association for the Advancement in Medical instrumentation guidelines for non-invasive blood pressure device. Data from 167 volunteers were analyzed for this purpose. Paired t tests were used to test for significant difference in mean systolic and diastolic blood pressure between devices for overall and by mid-arm circumference categories. To test for systematic differences between the two devices, we generated Bland-Altman graphs. Sensitivity, specificity, and Kappa statistics were calculated to assess between-device agreement for high (≥ 130/80 mmHg) and not high (

Using a population-based, representative telephone survey, ~930 000 New York City residents had COVID-19 illness beginning 20 March–30 April 2020, a period with limited testing. For every 1000 persons estimated with COVID-19 illness, 141.8 were tested and reported as cases, 36.8 were hospitalized, and 12.8 died, varying by demographic characteristics.

Context Disease burden may vary substantively across neighborhoods in an urban setting. Yet, data available for monitoring chronic conditions at the neighborhood level are scarce. Large health care data sets have potential to complement population health surveillance. Few studies have examined the utility of health care data for neighborhood-level surveillance. Objective We examined the use of primary care electronic health records (EHRs) and emergency department (ED) claims for identifying neighborhoods with higher chronic disease burden and neighborhood-level prevalence estimation. Design Comparison of hypertension and diabetes estimates from EHRs and ED claims with survey-based estimates. Setting Forty-two United Hospital Fund neighborhoods in New York City. Participants The EHR sample comprised 708 452 patients from the Hub Population Health System (the Hub) in 2015, and the ED claim sample comprised 1 567 870 patients from the Statewide Planning and Research Cooperative System in 2015. We derived survey-based estimates from 2012 to 2016 Community Health Survey (n = 44 189). Main outcome measure We calculated hypertension and diabetes prevalence estimates by neighborhood from each data source. We obtained Pearson correlation and absolute difference between EHR-based or claims-based estimates and survey-based estimates. Results Both EHR-based and claims-based estimates correlated strongly with survey-based estimates for hypertension (0.91 and 0.72, respectively) and diabetes (0.83 and 0.82, respectively) and identified similar neighborhoods of higher burden. For hypertension, 10 and 17 neighborhoods from the EHRs and ED claims, respectively, had an absolute difference of more than 5 percentage points from the survey-based estimate. For diabetes, 15 and 4 neighborhoods from the EHRs and ED claims, respectively, differed from the survey-based estimate by more than 5 percentage points. Conclusions Both EHRs and ED claims data are useful for identifying neighborhoods with greater disease burden and have potential for monitoring chronic conditions at the neighborhood level.

Mercury is a toxic metal that can be measured in human blood and urine. Population-based biomonitoring from 2004 guided New York City (NYC) Department of Health and Mental Hygiene (DOHMH) efforts to reduce exposures by educating the public about risks and benefits of fish consumption—a predominant source of exposure in the general population—and removing mercury-containing skin-lightening creams and other consumer products from the marketplace. We describe changes in exposures over the past decade in relation to these local public health actions and in the context of national changes by comparing mercury concentrations measured in blood (1201 specimens) and urine (1408 specimens) from the NYC Health and Nutrition Examination Survey (NYC HANES) 2013–2014 with measurements from NYC HANES 2004 and National Health and Nutrition Examination Surveys (NHANES) 2003–2004 and 2013–2014. We found that NYC adult blood and urine geometric mean mercury concentrations decreased 46% and 45%, respectively. Adult New Yorkers with blood mercury concentration ≥ 5 μg/L (the New York State reportable level) declined from 24.8% (95% CL = 22.2%, 27.7%) to 12.0% (95% CL = 10.1%, 14.3%). The decline in blood mercury in NYC was greater than the national decline, while the decline in urine mercury was similar. As in 2004, Asian New Yorkers had higher blood mercury concentrations than other racial/ethnic groups. Foreign-born adults of East or Southeast Asian origin had the highest prevalence of reportable levels (29.7%; 95% CL = 21.0%, 40.1%) across sociodemographic groups, and Asians generally were the most frequent fish consumers, eating on average 11 fish meals in the past month compared with 7 among other groups (p

Depression is responsible for a large burden of disability in the USA. We estimated the prevalence of depression in the New York City (NYC) adult population in 2013–14 and examined associations with demographics, health behaviors, and employment status. Data from the 2013–14 New York City Health and Nutrition Examination Survey, a population-based examination study, were analyzed, and 1459 participants met the inclusion criteria for this analysis. We defined current symptomatic depression by a Patient Health Questionnaire (PHQ-9) score ≥ 10. Overall, 8.3% of NYC adults had current symptomatic depression. New Yorkers with current symptomatic depression were significantly more likely to be female, Latino, and unemployed yet not looking for work; they were also significantly more likely to have less than a high school education and to live in a high-poverty neighborhood. Socioeconomic inequalities in mental health persist in NYC and highlight the need for better diagnosis and treatment.

While gender and racial/ethnic disparities in cardiovascular disease (CVD) risk factors have each been well characterized, few studies have comprehensively examined how patterns of major CVD risk factors vary and intersect across gender and major racial/ethnic groups, considered together. Using data from New York City Health and Nutrition Examination Survey 2013–2014—a population-based, cross-sectional survey of NYC residents ages 20 years and older—we measured prevalence of obesity, hypertension, hypercholesterolemia, smoking, and diabetes across gender and race/ethnicity groups for 1527 individuals. We used logistic regression with predicted marginal to estimate age-adjusted prevalence ratio by gender and race/ethnicity groups and assess for potential additive and multiplicative interaction. Overall, women had lower prevalence of CVD risk factors than men, with less hypertension (p = 0.040), lower triglycerides (p

Objectives: Cardiovascular disease (CVD) is the leading cause of mortality in the United States. The risk for developing CVD is usually calculated and communicated to patients as a percentage. The calculation of heart age—defined as the predicted age of a person’s vascular system based on the person’s CVD risk factor profile—is an alternative method for expressing CVD risk. We estimated heart age among adults aged 30-74 in New York City and examined disparities in excess heart age by race/ethnicity and sex. Methods: We applied data from the 2011, 2013, and 2015 New York State Behavioral Risk Factor Surveillance System to the non–laboratory-based Framingham risk score functions to calculate 10-year CVD risk and heart age by sex, race/ethnicity, and selected sociodemographic groups and risk factors. Results: Of 6117 men and women in the study sample, the average heart age was 5.7 years higher than the chronological age, and 2631 (43%) adults had a predicted heart age ≥5 years older than their chronological age. Mean excess heart age increased with age (from 0.7 year among adults aged 30-39 to 11.2 years among adults aged 60-74) and body mass index (from 1.1 year among adults with normal weight to 11.8 years among adults with obesity). Non-Latino white women had the lowest mean excess heart age (2.3 years), and non-Latino black men and women had the highest excess heart age (8.4 years). Conclusions: Racial/ethnic and sex disparities in CVD risk persist among adults in New York City. Use of heart age at the population level can support public awareness and inform targeted programs and interventions for population subgroups most at risk for CVD.

Introduction Exposure to secondhand smoke is hazardous and can cause cancer, coronary heart disease, and birth defects. New York City (NYC) and other jurisdictions have established smoke-free air laws in the past 10-15 years. Methods NYC Health and Nutrition Examination Survey (HANES) 2013-2014 was a population-based survey of NYC residents, aged 20 years and older, in which biospecimens were collected and cotinine levels were measured. Secondhand smoke exposure was assessed by demographics and risk factors and compared with that from NYC HANES 2004 and national HANES. Results More than a third (37.1%, 95% confidence interval [CI] = 33.3%-41.2%) of nonsmoking adult New Yorkers were exposed to secondhand smoke, defined as a cotinine level of 0.05-10ng/mL. This was significantly lower than in 2004 NYC HANES, when 56.7% (95% CI = 53.6%-59.7%) of nonsmokers were exposed to secondhand smoke, but was greater than the proportion of adults exposed nationwide, as measured by national HANES (24.4%, 95% CI = 22.0%-26.9% in 2011-2012). Men, non-Hispanic blacks, adults aged 20-39, those with less education, and those living in high-poverty neighborhoods were more likely to be exposed. Conclusions There has been a large decrease in secondhand smoke exposure in NYC, although disparities persist. The decrease may be the result of successful policies to limit exposure to secondhand smoke in public places and of smokers smoking fewer cigarettes per day. Yet NYC residents still experience more secondhand smoke exposure than US residents overall. Possible explanations include multiunit housing, greater population density, and pedestrian exposure. Implications Measuring exposure to secondhand smoke can be difficult, and few studies have monitored changes over time. This study uses serum cotinine, a nicotine metabolite, from a local population-based examination survey, the NYC HANES 2013-2014, to examine exposure to secondhand smoke in an urban area that has implemented stringent antismoking laws. Comparison with NYC HANES conducted 10 years ago allows for an assessment of changes in the last decade in the context of municipal tobacco control policies. Results may be helpful to jurisdictions considering implementing similar tobacco control policies.

Introduction Increasing adoption of electronic health record (EHR) systems by health care providers presents an opportunity for EHR-based population health surveillance. EHR data, however, may be subject to measurement error because of factors such as data entry errors and lack of documentation by physicians. We investigated the use of a calibration model to reduce bias of prevalence estimates from the New York City (NYC) Macroscope, an EHR-based surveillance system. Methods We calibrated 6 health indicators to the 2013-2014 NYC Health and Nutrition Examination Survey (NYC HANES) data: hypertension, diabetes, smoking, obesity, influenza vaccination, and depression. We classified indicators into having low measurement error or high measurement error on the basis of whether the proportion of misclassification (ie, false-negative or false-positive cases) was greater than 15% in 190 reviewed charts. We compared bias (ie, absolute difference between NYC Macroscope estimates and NYC HANES estimates) before and after calibration. Results The health indicators with low measurement error had the same bias after calibration as before calibration (diabetes, 2.5 percentage points; smoking, 2.5 percentage points; obesity, 3.5 percentage points; hypertension, 1.1 percentage points). For indicators with high measurement error, bias decreased from 10.8 to 2.5 percentage points for depression, and from 26.7 to 8.4 percentage points for influenza vaccination. Conclusion The calibration model has the potential to reduce bias of prevalence estimates from EHR-based surveillance systems for indicators with high measurement errors. Further research is warranted to assess the utility of the current calibration model for other EHR data and additional indicators.

National examination surveys provide trend information on diabetes prevalence, diagnoses, and control. Few localities have access to such information. Using a similar design as the National Health and Nutrition Examination Survey (NHANES), two NYC Health and Nutrition Examination Surveys (NYC HANES) were conducted over a decade, recruiting adults ≥ 20 years using household probability samples (n = 1808 in 2004; n = 1246 in 2013–2014) and physical exam survey methods benchmarked against NHANES. Participants had diagnosed diabetes if told by a health provider they had diabetes, and undiagnosed diabetes if they had no diagnosis but a fasting plasma glucose ≥ 126 mg/dl or A1C ≥ 6.5%. We found that between 2004 and 2014, total diabetes prevalence (diagnosed and undiagnosed) in NYC increased from 13.4 to 16.0% (P = 0.089). In 2013–2014, racial/ethnic disparities in diabetes burden had widened; diabetes was highest among Asians (24.6%), and prevalence was significantly lower among non-Hispanic white adults (7.7%) compared to that among other racial/ethnic groups (P 9%), decreased from 26.9 to 18.0% (P = 0.269), though both were non-significant. While local racial/ethnic disparities in diabetes prevalence persist, findings suggest modest improvements in diabetes diagnosis and management.

The objective of this study was to measure change in obesity prevalence among New York City (NYC) adults from 2004 to 2013–2014 and assess variation across sociodemographic subgroups. We used objectively measured height and weight data from the NYC Health and Nutrition Examination Survey to calculate relative percent change in obesity (≥ 30 kg/m(2)) between 2004 (n = 1987) and 2013–2014 (n = 1489) among all NYC adults and sociodemographic subgroups. We also examined changes in self-reported proxies for energy imbalance. Estimates were age-standardized and statistical significance was evaluated using two-tailed T tests and multivariable regression (p

Introduction: The New York City (NYC) Macroscope is an electronic health record (EHR) surveillance system based on a distributed network of primary care records from the Hub Population Health System. In a previous 3-part series published in eGEMS, we reported the validity of health indicators from the NYC Macroscope; however, questions remained regarding their generalizability to other EHR surveillance systems.Methods: We abstracted primary care chart data from more than 20 EHR software systems for 142 participants of the 2013-14 NYC Health and Nutrition Examination Survey who did not contribute data to the NYC Macroscope. We then computed the sensitivity and specificity for indicators, comparing data abstracted from EHRs with survey data.Results: Obesity and diabetes indicators had moderate to high sensitivity (0.81-0.96) and high specificity (0.94-0.98). Smoking status and hypertension indicators had moderate sensitivity (0.78-0.90) and moderate to high specificity (0.88-0.98); sensitivity improved when the sample was restricted to records from providers who attested to Stage 1 Meaningful Use. Hyperlipidemia indicators had moderate sensitivity (≥0.72) and low specificity (≤0.59), with minimal changes when restricting to Stage 1 Meaningful Use.Discussion: Indicators for obesity and diabetes used in the NYC Macroscope can be adapted to other EHR surveillance systems with minimal validation. However, additional validation of smoking status and hypertension indicators is recommended and further development of hyperlipidemia indicators is needed.Conclusion: Our findings suggest that many of the EHR-based surveillance indicators developed and validated for the NYC Macroscope are generalizable for use in other EHR surveillance systems.

OBJECT There has been renewed interest in the application of concentrated antibiotic powder to surgical wounds as a method to decrease infection rates. While there is substantial medical literature describing the effectiveness and complications associated with vancomycin and gentamycin powders, very little has been reported regarding the safety and effectiveness of bacitracin powder in surgical wounds. In this paper the authors report their detailed analysis of potential bacitracin powder-related complications in a population of pediatric patients who underwent shunt surgery. METHODS A detailed retrospective analysis was completed of all CSF shunt surgeries performed by the corresponding author at a large children’s hospital between 2001 and 2013. This cohort consisted of many patients who were the subject of a previous report that showed the use of bacitracin powder in shunt wounds potentially decreased infection rates. Data were collected regarding the most common known complications of bacitracin, i.e., anaphylaxis, wound healing difficulties, and renal dysfunction. Data were stratified by typical demographic, medical, and surgical variables, including whether bacitracin powder was applied to wounds prior to closure. RESULTS A total of 597 patients were reviewed in the analysis: 389 underwent surgery without bacitracin powder and 208 had concentrated bacitracin powder applied to the wounds prior to closure. The application of bacitracin powder was not associated with anaphylaxis (n = 0 both groups) or with an increase in wound breakdown (n = 5 in the control group, n = 0 in the bacitracin powder group) or renal dysfunction (creatinine/estimated glomerular filtration rate) using both comparative and multivariate analyses between the 2 groups. The sample size evaluating renal function was significantly lower (range 6–320) than that of anaphylaxis and wound breakdown analysis because only clinical values acquired during the routine care of these patients were available for analysis. The only significant difference in demographics was the more frequent use of intrathecal vancomycin and gentamycin in patients who received bacitracin powder (n = 1 for controls, n = 21 for bacitracin powder). In the multivariate analysis, only 1 factor, surgery performed on a premature infant within the first 3 months of life, was independently associated with a change in creatinine at 3 months (creatinine decreased by 0.18) compared with the level before surgery (p < 0.0001). Bacitracin powder was not a significant factor. CONCLUSIONS To the authors’ knowledge, this is the first study to systematically analyze the potential complications of concentrated bacitracin powder applied to surgical wounds. The use of topical bacitracin powder in CSF shunt wounds was not associated with anaphylaxis, wound breakdown, or renal dysfunction. Further study using standardized protocols is necessary before widespread use can be recommended.

Electronic health records (EHRs) are transforming the practice of clinical medicine, but the extent to which they are being harnessed to advance public health goals remains uncertain. Data extracted from integrated EHR networks offer the potential for almost real-time determination of the health status of populations in care, for targeting interventions to vulnerable populations, and for monitoring the impact of such initiatives over time. This is especially true in ambulatory care settings, which are uniquely suited for monitoring population health indicators including risk factors and disease management indicators associated with chronic diseases. As efforts gather steam to integrate health data across delivery systems, large networks of electronic patient information are increasingly emerging. Few of the national population health surveillance systems that rely on EHR data have progressed beyond laying groundwork to launch and maintain EHR-based surveillance, but a limited number of more focused or local efforts have demonstrated innovation in population health surveillance. Common challenges include incompleteness of population coverage, lack of interoperability across data systems, and variable data quality. This review defines progress, opportunities, and challenges in using EHR data for population health surveillance.

Purpose Capacity to monitor non-communicable diseases (NCDs) at state or local levels is limited. Emerging approaches include using biomeasures and electronic health record (EHR) data. In 2004, New York City (NYC) performed a population-based health study on adult residents using biomeasures (NYC Health and Nutrition Examination Study, or NYC HANES), modeled after NHANES. A second NYC HANES was launched in 2013 to examine change over time, evaluate municipal policies, and validate a proposed EHR-based surveillance system. We describe the rationale and methods of NYC HANES 2013–2014. Methods NYC HANES was a population-based, cross-sectional survey of NYC adults using three-stage cluster sampling. Between August 2013 and June 2014, selected participants completed a health interview and physical exam (blood pressure, body mass index, and waist circumference). Fasting biomeasures included diabetes, lipid profiles, kidney function, environmental biomarkers, and select infectious diseases. Results Of the 3065 households approached, 2742 were eligible and 1827 were successfully screened (67%). A total of 1524 of eligible participants completed the survey (54%), for an overall response rate of 36%. Conclusion Completing a second NYC HANES a decade after the first study affords an opportunity to understand changes in prevalence, awareness and control of NCDs and evaluate municipal efforts to manage them., Highlights • NYC HANES describes chronic conditions and allows evaluation of municipal policies. • Innovations in survey research methods inform chronic disease surveillance. • Emerging directions include using EMRs for population surveillance purposes.

With 87% of providers using electronic health records (EHRs) in the United States, EHRs have the potential to contribute to population health surveillance efforts. However, little is known about using EHR data outside syndromic surveillance and quality improvement. We created an EHR-based population health surveillance system called the New York City (NYC) Macroscope and assessed the validity of diabetes, hyperlipidemia, hypertension, smoking, obesity, depression, and influenza vaccination indicators. The NYC Macroscope uses aggregate data from a network of outpatient practices. We compared 2013 NYC Macroscope prevalence estimates with those from a population-based, in-person examination survey, the 2013–2014 NYC Health and Nutrition Examination Survey. NYC Macroscope diabetes, hypertension, smoking, and obesity prevalence indicators performed well, but depression and influenza vaccination estimates were substantially lower than were survey estimates. Ongoing validation will be important to monitor changes in validity over time as EHR networks mature and to assess new indicators. We discuss NYC’s experience and how this project fits into the national context. Sharing lessons learned can help achieve the full potential of EHRs for population health surveillance.

INTRODUCTION Electronic health record (EHR) systems provide an opportunity to use a novel data source for population health surveillance. Validation studies that compare prevalence estimates from EHRs and surveys most often use difference testing, which can, because of large sample sizes, lead to detection of significant differences that are not meaningful. We explored a novel application of the two one-sided t test (TOST) to assess the equivalence of prevalence estimates in 2 population-based surveys to inform margin selection for validating EHR-based surveillance prevalence estimates derived from large samples. METHODS We compared prevalence estimates of health indicators in the 2013 Community Health Survey (CHS) and the 2013-2014 New York City Health and Nutrition Examination Survey (NYC HANES) by using TOST, a 2-tailed t test, and other goodness-of-fit measures. RESULTS A ±5 percentage-point equivalence margin for a TOST performed well for most health indicators. For health indicators with a prevalence estimate of less than 10% (extreme obesity [CHS, 3.5%; NYC HANES, 5.1%] and serious psychological distress [CHS, 5.2%; NYC HANES, 4.8%]), a ±2.5 percentage-point margin was more consistent with other goodness-of-fit measures than the larger percentage-point margins. CONCLUSION A TOST with a ±5 percentage-point margin was useful in establishing equivalence, but a ±2.5 percentage-point margin may be appropriate for health indicators with a prevalence estimate of less than 10%. Equivalence testing can guide future efforts to validate EHR data.

Introduction Racial/ethnic minority adults have higher rates of hypertension than non-Hispanic white adults. We examined the prevalence of hypertension among Hispanic and Asian subgroups in New York City. Methods Data from the 2013-2014 New York City Health and Nutrition Examination Survey were used to assess hypertension prevalence among adults (aged ≥20) in New York City (n = 1,476). Hypertension was measured (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or self-reported hypertension and use of blood pressure medication). Participants self-reported race/ethnicity and country of origin. Multivariable logistic regression models assessed differences in prevalence by race/ethnicity and sociodemographic and health-related characteristics. Results Overall hypertension prevalence among adults in New York City was 33.9% (43.5% for non-Hispanic blacks, 38.0% for Asians, 33.0% for Hispanics, and 27.5% for non-Hispanic whites). Among Hispanic adults, prevalence was 39.4% for Dominican, 34.2% for Puerto Rican, and 27.5% for Central/South American adults. Among Asian adults, prevalence was 43.0% for South Asian and 39.9% for East/Southeast Asian adults. Adjusting for age, sex, education, and body mass index, 2 major racial/ethnic minority groups had higher odds of hypertension than non-Hispanic whites: non-Hispanic black (AOR [adjusted odds ratio], 2.6; 95% confidence interval [CI], 1.7-3.9) and Asian (AOR, 2.0; 95% CI, 1.2-3.4) adults. Two subgroups had greater odds of hypertension than the non-Hispanic white group: East/Southeast Asian adults (AOR, 2.8; 95% CI, 1.6-4.9) and Dominican adults (AOR, 1.9; 95% CI, 1.1-3.5). Conclusion Racial/ethnic minority subgroups vary in hypertension prevalence, suggesting the need for targeted interventions.

An intradural somatic-to-autonomic anastomosis, or Xiao procedure, has been described to create a “skin-CNS-bladder” reflex that improves bladder and bowel function in patients with neurogenic bladder and bowel dysfunction. The authors present their experience with a 10-year-old boy with chronic neurogenic bladder and bowel dysfunction related to spinal cord injury who underwent the Xiao procedure. After undergoing a left L-5 ventral root to left S2–3 intradural anastomosis, the patient reported that his bladder and bowel dysfunction improved between 6 and 12 months. Two years after the procedure, however, he reported that there was no change in his bladder or bowel dysfunction as compared with his condition prior to the procedure. Frequent, systematic multidisciplinary evaluations produced conflicting data. Electrophysiological and histological evaluation of the previously performed anastomosis during surgical reexploration 3 years after the Xiao procedure revealed that the anastomosis was in anatomical continuity but neuroma formation had prevented reinnervation. Nerve action potentials were not demonstrable across the anastomosis, and stimulation of the nerve above and below the anastomosis created no bladder or perineal contractions. This is the first clinical report on the outcome of the Xiao procedure in a child with spinal cord injury outside of China. It is impossible to draw broad conclusions about the efficacy of the procedure based on a single patient with no demonstrable benefit. However, future studies should carefully interpret transient improvements in bladder function, urodynamic findings, and the patient's ability to void in response to scratching after the Xiao procedure. The authors' experience with the featured patient, in whom reinnervation could not be demonstrated, suggests that such changes could be related to factors other than the establishment of a skin-CNS-bladder reflex as a result of a somatic-to-autonomic anastomosis.

Introduction: Electronic health records (EHRs) have the potential to offer real-time, inexpensive standardized health data about chronic health conditions. Despite rapid expansion, EHR data evaluations for chronic disease surveillance have been limited. We present design and methods for the New York City (NYC) Macroscope, an EHR-based chronic disease surveillance system.This methods report is the first in a three part series describing the development and validation of the NYC Macroscope. This report describes in detail the infrastructure underlying the NYC Macroscope; indicator definitions; design decisions that were made to maximize data quality; characteristics of the population sampled; completeness of data collected; and lessons learned from doing this work. The second report describes the methods used to evaluate the validity and robustness of NYC Macroscope prevalence estimates; presents validation results for estimates of obesity, smoking, depression and influenza vaccination; and discusses the implications of our findings for NYC and for other jurisdictions embarking on similar work. The third report applies the same validation methods to metabolic outcomes, including the prevalence, treatment and control of diabetes, hypertension and hyperlipidemia.Methods: We designed the NYC Macroscope for comparison to a local “gold standard,” the 2013-14 NYC Health and Nutrition Examination Survey, and the telephonic 2013 Community Health Survey. NYC Macroscope indicators covered prevalence, treatment, and control of diabetes, hypertension, and hyperlipidemia; and prevalence of influenza vaccination, obesity, depression and smoking. Indicators were stratified by age, sex, and neighborhood poverty, and weighted to the in-care NYC population and limited to primary care patients. Indicator queries were distributed to a virtual network of primary care practices; 392 practices and 716,076 adult patients were retained in the final sample.Findings: The NYC Macroscope covered 10% of primary care providers and 15% of all adult patients in NYC in 2013 (8-47% of patients by neighborhood). Data completeness varied by domain from 98% for blood pressure among patients with hypertension to 33% for depression screening.Discussion: Design and validation efforts undertaken by NYC are described here to provide one potential blueprint for leveraging EHRs for population health monitoring. To replicate a model like NYC Macroscope, jurisdictions should establish buy-in; build informatics capacity; use standard, simple case definitions; establish documentation quality thresholds; restrict to primary care providers; and weight the sample to a target population.

Introduction: Electronic health records (EHRs) can potentially extend chronic disease surveillance, but few EHR-based initiatives tracking population-based metrics have been validated for accuracy. We designed a new EHR-based population health surveillance system for New York City (NYC) known as NYC Macroscope. This report is the third in a 3-part series describing the development and validation of that system. The first report describes governance and technical infrastructure underlying the NYC Macroscope. The second report describes validation methods and presents validation results for estimates of obesity, smoking, depression and influenza vaccination. In this third paper we present validation findings for metabolic indicators (hypertension, hyperlipidemia, diabetes).Methods: We compared EHR-based estimates to those from a gold standard surveillance source – the 2013-2014 NYC Health and Nutrition Examination Survey (NYC HANES) – overall and stratified by sex and age group, using the two one-sided test of equivalence and other validation criteria.Results: EHR-based hypertension prevalence estimates were highly concordant with NYC HANES estimates. Diabetes prevalence estimates were highly concordant when measuring diagnosed diabetes but less so when incorporating laboratory results. Hypercholesterolemia prevalence estimates were less concordant overall. Measures to assess treatment and control of the 3 metabolic conditions performed poorly.Discussion: While indicator performance was variable, findings here confirm that a carefully constructed EHR-based surveillance system can generate prevalence estimates comparable to those from gold-standard examination surveys for certain metabolic conditions such as hypertension and diabetes.Conclusions: Standardized EHR metrics have potential utility for surveillance at lower annual costs than surveys, especially as representativeness of contributing clinical practices to EHR-based surveillance systems increases.

INTRODUCTION Electronic health records (EHRs) from primary care providers can be used for chronic disease surveillance; however, EHR-based prevalence estimates may be biased toward people who seek care. This study sought to describe the characteristics of an in-care population and compare them with those of a not-in-care population to inform interpretation of EHR data. METHODS We used data from the 2013-2014 New York City Health and Nutrition Examination Survey (NYC HANES), considered the gold standard for estimating disease prevalence, and the 2013 Community Health Survey, and classified participants as in care or not in care, on the basis of their report of seeing a health care provider in the previous year. We used χ(2) tests to compare the distribution of demographic characteristics, health care coverage and access, and chronic conditions between the 2 populations. RESULTS According to the Community Health Survey, approximately 4.1 million (71.7%) adults aged 20 or older had seen a health care provider in the previous year; according to NYC HANES, approximately 4.7 million (75.1%) had. In both surveys, the in-care population was more likely to be older, female, non-Hispanic, and insured compared with the not-in-care population. The in-care population from the NYC HANES also had a higher prevalence of diabetes (16.7% vs 6.9%; P < .001), hypercholesterolemia (35.7% vs 22.3%; P < .001), and hypertension (35.5% vs 26.4%; P < .001) than the not-in-care population. CONCLUSION Systematic differences between in-care and not-in-care populations warrant caution in using primary care data to generalize to the population at large. Future efforts to use primary care data for chronic disease surveillance need to consider the intended purpose of data collected in these systems as well as the characteristics of the population using primary care.

The New York City Department of Health has been developing two public health surveillance systems for chronic diseases. The first is the NYC Macroscope, which is built on a distributed query network of 740 New York City ambulatory practices all using proprietary software from one EHR vendor. The second model, Query Health, still in its initial phase, accesses data collected by a Health Information Exchange. This study compares these two models for potential disease surveillance and public health application.

The New York City (NYC) Department of Health and Mental Hygiene (Health Department) surveyed practicing NYC physicians to quantify Health Department resource use. Although the Health Department successfully reaches most physicians, and information is valued in practice, knowledge of several key resources was low. Findings suggested 3 recommendations for all local health departments seeking to enhance engagement with practicing physicians: (1) capitalize on physician interest, (2) engage physicians early and often, and (3) make interaction with the health department easy. Also, older physicians may require targeted outreach.

The objective of this study was to measure change in obesity prevalence among New York City (NYC) adults from 2004 to 2013-2014 and assess variation across sociodemographic subgroups. We used objectively measured height and weight data from the NYC Health and Nutrition Examination Survey to calculate relative percent change in obesity (≥ 30 kg/m

Health departments need the capacity to rapidly expand and modify surveillance during a changing outbreak., On April 23, 2009, the New York City Department of Health and Mental Hygiene (DOHMH) was notified of a school outbreak of respiratory illness; 2 days later the infection was identified as pandemic (H1N1) 2009. This was the first major outbreak of the illness in the United States. To guide decisions on the public health response, the DOHMH used active hospital-based surveillance and then enhanced passive reporting to collect data on demographics, risk conditions, and clinical severity. This surveillance identified 996 hospitalized patients with confirmed or probable pandemic (H1N1) 2009 virus infection from April 24 to July 7; fifty percent lived in high-poverty neighborhoods. Nearly half were

Hypophosphatasia (HPP) is a rare, heritable, metabolic bone disease due to deficient activity of the tissue-nonspecific isoenzyme of alkaline phosphatase. The infantile form features severe rickets often causing death in the first year of life from respiratory complications. There is no established medical treatment. In 1997, an 8-month-old girl with worsening and life-threatening infantile HPP improved considerably after marrow cell transplantation.Our aim was to better understand and to advance these encouraging transplantation results.In 1999, based on emerging mouse transplantation models involving implanted donor bone fragments as well as osteoblast-like cells cultured from bone, we treated a 9-month-old girl suffering a similar course of infantile HPP.Four months later, radiographs demonstrated improved skeletal mineralization. Twenty months later, PCR analysis of adherent cells cultured from recipient bone suggested the presence of small amounts of paternal (donor) DNA despite the absence of hematopoietic engraftment. This patient, now 8 yr old (7 yr after transplantation), is active and growing, and has the clinical phenotype of the more mild, childhood form of HPP.Cumulative experience suggests that, after immune tolerance, donor bone fragments and marrow may provide precursor cells for distribution and engraftment in the skeletal microenvironment in HPP patients to form tissue-nonspecific isoenzyme of alkaline phosphatase-replete osteoblasts that can improve mineralization.

There are few data comparing risk factors for catheter-related (CR) versus non-CR bloodstream infection (BSI) or for BSI caused by gram-positive versus gram-negative organisms. The aims of this study were to compare risk factors for CR versus non-CR BSI and to compare risk factors for BSI associated with gram-negative versus gram-positive organisms among infants hospitalized in two neonatal intensive care units (NICUs).Data were collected prospectively over a 2-year period to assess risk factors among 2,935 neonates from two NICUs.Among all neonates, in addition to low birth weight and presence of a central venous catheter, hospitalization in NICU 1 (relative risk [RR]: 1.60, 95% confidence intervals [CI]: 1.14, 2.24) was a significant predictor of BSI. In neonates with a central catheter total parenteral nutrition (TPN) was a significant risk factor for BSI (RR: 4.69, 95% CI: 2.22, 9.87). Ventilator use was a significant risk factor for CR versus non-CR BSI (RR: 3.74, 95% CI: 1.87, 7.48), and significantly more CR BSI were caused by gram-positive (77.1%) than by gram-negative organisms (61.4%), P = .03.This study confirmed that central venous catheters and low birth weight were risk factors for neonates with late-onset healthcare-associated BSI and further elucidated the potential risks associated with TPN and ventilator use in subgroups of neonates with BSI. Additional studies are needed to examine the incremental risk of TPN among infants with central venous catheters and to understand the link between CR BSI and ventilator use. Preventive strategies for BSI in neonates in NICUs should continue to focus on limiting the use of invasive devices.

After the September 11, 2001 World Trade Center (WTC) disaster, recovery and clean-up efforts were concentrated at the WTC site and the Staten Island (SI) Fresh Kills landfill and barges. Research is limited regarding the long-term health effects of human remains exposure during clean-up and recovery work at the SI landfill and barges. We studied 1,592 WTC Health Registry enrollees who worked at the SI landfill, loading piers and barges after the 9/11/01 attacks to assess the relationship between remains exposure and persistent posttraumatic stress disorder (PTSD) 10-11 years later. A dose-response relationship was found between frequency of human remains exposure and persistent PTSD (adjusted odds ratio (AOR): every day (AOR) = 4.77; 95% confidence interval (CI): 2.00-11.52, almost every day (AOR) = 4.35; 95% CI: 1.75-10.80), and some days (AOR) = 2.98; 95% CI: 1.43-6.22). When exposed to human remains, sanitation workers had higher odds of persistent PTSD, compared to firefighters and police. In addition, respondents who scored lower on a social support scale had higher odds of persistent PTSD. The findings highlight the need for strategies to reduce the risk of PTSD associated with exposure to human remains in future disasters.

OBJECTIVE To describe diabetes prevalence in New York City by race/ethnicity and nativity. RESEARCH DESIGN AND METHODS Data were from the New York City 2002–2008 Community Health Surveys. Respondents were categorized on the basis of self-reported race/ethnicity and birth country: foreign-born South Asian (Indian subcontinent), foreign-born other Asian, U.S.-born non-Hispanic black, U.S.-born non-Hispanic white, and U.S.-born Hispanic. Diabetes status was defined by self-reported provider diagnosis. Multivariable models examined diabetes prevalence by race/ethnicity and birth country. RESULTS Prevalence among foreign-born South Asians was nearly twice that of foreign-born other Asians (13.6 vs. 7.4%, P = 0.001). In multivariable analyses, normal-BMI foreign-born South Asians had nearly five times the diabetes prevalence of comparable U.S.-born non-Hispanic whites (14.1 vs. 2.9%, P < 0.001) and 2.5 times higher prevalence than foreign-born other Asians (P < 0.001). CONCLUSIONS Evaluating Asians as one group masks the higher diabetes burden among South Asians. Researchers and clinicians should be aware of differences in this population.

Electronic health records (EHRs) are increasingly being adopted to improve quality of care in health care systems, but they also have potential to monitor health at the population level. Enhancing existing surveillance methods with innovative EHR use allows for strategic targeting of health resources, and data to guide and evaluate public health initiatives and policies. New York City is currently developing the NYC Macroscope, aggregating EHR data into a surveillance tool to inform public health decisions. We have outlined key issues in developing an EHR-based surveillance system, and proposed indicators for the NYC Macroscope.

Purpose: Nephrolithiasis in preterm infants rarely requires surgical management. When it persists despite conservative therapy, treatment options are not clearly defined. We report a single institutional experience with extracorporeal shock wave lithotripsy (ESWL)* *Dornier Medical Systems, Inc., Marietta, Georgia. for the treatment of these small infants.Materials and Methods: We treated 8 infants (mean age 13 months) with a history of prematurity and 9 persistent stones with a Dornier HM3 lithotriptor between 1996 and 1999. Mean weight was 7,700 gm. Of the infants 7 had been treated with furosemide for bronchopulmonary dysplasia and 1 presented with multiple anatomical abnormalities. Gantry modification with a wooden platform and polystyrene foam positioning was used for lung and visceral protection. Ureteral stents were placed in 5 patients before ESWL. Renal ultrasonography was performed before, and 2 and a mean of 8 weeks after ESWL. Stone risk factors in our population were investigated through a mu...

An inverse relationship between mortality and center volume has been established for several surgical procedures. Given the distinctiveness of pediatric renal transplantation and the large variation in center volume, investigation for relationships between center volume and graft outcome was pursued using the North American Pediatric Transplant Cooperative Study database. Center volume groups were based on the total number of pediatric transplants reported from 1987 to 1995. Centers reporting >100, 51–100, or ≤50 transplants were grouped as high- (n=11), moderate- (n=28), or low-volume (n=65), respectively. Differences between groups included increasing rates of cadaver donor graft thrombosis (2.4%, 4.3%, and 5.7%, P

A 7-year-old boy with asthma was receiving the leukotriene receptor antagonist pranlukast (Ultair; SmithKline Beecham; Pittsburgh) as part of an open-label clinical trial. The patient's asthma improved, and he remained asymptomatic; but routine study evaluations 9 to 12 months into therapy showed microhematuria, proteinuria, glucosuria, anemia, and renal insufficiency. Renal biopsy demonstrated changes classic for acute allergic tubulointerstitial nephritis (ATIN), with mixed interstitial inflammatory infiltrate including eosinophils. Within 6 months of pranlukast withdrawal, anemia resolved and urinary sediment and renal function normalized. The case demonstrates that hypersensitivity reaction to pranlukast and resultant ATIN is possible, and that periodic urine testing in patients receiving pranlukast should be considered.
