RESUMO
CONTEXT: Wisconsin-specific data revealed that not all Medicaid providers were testing children appropriately for blood lead levels and not all blood lead tests were reported to the Department of Health Services, Childhood Lead Poisoning Prevention Program. The Medicaid program requires blood lead screening for all Medicaid-enrolled children at specific ages. Wisconsin state law requires reporting of all blood lead test results. Projects were implemented to encourage appropriate testing for Medicaid-enrolled children and improve blood lead surveillance. METHODS: Medicaid billing data were linked to blood lead data to identify Medicaid-enrolled children who had not received the required tests. Medicaid provider report cards were distributed annually from 2006 to 2011 to inform providers of their compliance with federal testing requirements and of the names of children within their practice who had not been tested. Blood lead tests billed to Medicaid but not in the blood lead database were identified and billing providers were contacted to obtain the test report. RESULTS: The number of children tested increased from 81 834 children per year in 2006 to 106 003 children per year in 2010. Testing of Medicaid-enrolled children increased by 31% from 2006 to 2010. The percentage of Medicaid-enrolled children receiving an age-appropriate test increased from 46% in 2004 to a high of 55% in 2010. There were 9035 blood lead tests identified in the Medicaid billing data that had not been reported from 2007 to 2015. There were 468 billing providers who had unreported tests. All sites with unreported tests were contacted, 84% of test results were obtained, and 14% of test records could not be retrieved. Outpatient clinics accounted for the majority of all unreported tests (72%) and irretrievable test records (74%). DISCUSSION: Childhood lead poisoning prevention programs can effectively utilize Medicaid data to increase testing and improve blood lead surveillance. Primary health care providers should ensure that Medicaid-enrolled children in their care receive the age-appropriate tests. Many Wisconsin health care providers lack awareness of blood lead test reporting requirements. Outpatient clinics account for the largest proportion of unreported tests and highest priority should be given working with these sites to improve reporting practices.

An estimated 115,000 firearm injuries occur annually in the United States, and approximately 70% are nonfatal (1). Retained bullet fragments (RBFs) are an infrequently reported, but important, cause of lead toxicity; symptoms are often nonspecific and can appear years after suffering a gunshot wound (2,3). Adult blood lead level (BLL) screening is most commonly indicated for monitoring of occupational lead exposure; routine testing of adults with RBFs is infrequent (3). States collaborate with CDC's National Institute for Occupational Safety and Health (NIOSH) to monitor elevated BLLs through the Adult Blood Lead Epidemiology and Surveillance (ABLES) program (4,5). To help assess the public health burden of RBFs, data for persons with BLLs ≥10 µg/dL reported to ABLES during 2003-2012 were analyzed. An RBF-associated case was defined as a BLL ≥10 µg/dL in a person with an RBF. A non-RBF-associated case was defined as a BLL ≥10 µg/dL without an RBF. During 2003-2012, a total of 145,811 persons aged ≥16 years with BLLs ≥10 µg/dL were reported to ABLES in 41 states. Among these, 457 RBF-associated cases were identified with a maximum RBF-associated BLL of 306 µg/dL. RBF-associated cases accounted for 0.3% of all BLLs ≥10 µg/dL and 4.9% of BLLs ≥80 µg/dL. Elevated BLLs associated with RBFs occurred primarily among young adult males in nonoccupational settings. Low levels of suspicion of lead toxicity from RBFs by medical providers might cause a delay in diagnosis (3). Health care providers should inquire about an RBF as the potential cause for lead toxicity in an adult with an elevated BLL whose lead exposure is undetermined.

Hypothermia is defined as a core body temperature of <95°F (<35°C) and is caused by environmental exposure, drug intoxication, or metabolic or nervous system dysfunction. Exposure to cold is a leading cause of weather-related mortality and is responsible for approximately twice the number of deaths annually as exposure to heat in the United States. To understand the risk factors for hypothermia-related death and improve prevention efforts, during January 1-April 30, 2014, a period of record low temperatures, the Wisconsin Division of Public Health began active surveillance for hypothermia. Suspected hypothermia-related deaths were reported by coroners or medical examiners and identified in death records. Hypothermia was confirmed as the cause of death by review of death investigation narratives. This report describes three selected cases of hypothermia-related deaths in Wisconsin and summarizes characteristics of all cases that occurred in the state during the period of active surveillance. A summary of hypothermia-related deaths for the United States during 2003-2013 also is presented for comparison and to assess national mortality trends. Hypothermia continues to be an important cause of weather-related death. Key risk factors include drug intoxication, mental illness, and social isolation. State and local health agencies might need to focus outreach on vulnerable populations and target interventions for groups at highest risk for death.

On April 30, 2015, the Wisconsin Division of Public Health (WDPH) was notified by a local health department of an elevated blood lead level (BLL) in a female patient aged 64 years. All Wisconsin laboratories are required to provide BLL testing results performed on any state resident to WDPH, and WDPH and local health departments are statutorily mandated to investigate any single BLL ≥20 µg/dL or BLLs that are persistently ≥15 µg/dL. Review of medical records revealed that the patient had developed progressive fatigue and shortness of breath during a period of multiple weeks that prompted inpatient medical evaluation. Hemoglobin level was 8.3 g/dL (normal range for age and sex of patient = 12.5-15.0 g/dL), and peripheral blood smear showed normochromic, normocytic red blood cells with basophilic stippling. A BLL was obtained and found to be 85.8 µg/dL. Urine toxic metals tests revealed mercury and aluminum levels in the normal range. Combined methylated and inorganic urine arsenic levels were slightly elevated at 53.3 µg/L (normal = <18.9 µg/L). The patient was discharged for outpatient lead chelation therapy with oral meso-2,3-dimercaptosuccinic acid.

On December 13, 2014, the emergency management system in Lake Delton, Wisconsin, was notified when a male hockey player aged 20 years lost consciousness after participation in an indoor hockey tournament that included approximately 50 hockey players and 100 other attendees. Elevated levels of carbon monoxide (CO) (range = 45 ppm-165 ppm) were detected by the fire department inside the arena. The emergency management system encouraged all players and attendees to seek medical evaluation for possible CO poisoning. The Wisconsin Department of Health Services (WDHS) conducted an epidemiologic investigation to determine what caused the exposure and to recommend preventive strategies. Investigators abstracted medical records from area emergency departments (EDs) for patients who sought care for CO exposure during December 13-14, 2014, conducted a follow-up survey of ED patients approximately 2 months after the event, and conducted informant interviews. Ninety-two persons sought ED evaluation for possible CO exposure, all of whom were tested for CO poisoning. Seventy-four (80%) patients had blood carboxyhemoglobin (COHb) levels consistent with CO poisoning; 32 (43%) CO poisoning cases were among hockey players. On December 15, the CO emissions from the propane-fueled ice resurfacer were demonstrated to be 4.8% of total emissions when actively resurfacing and 2.3% when idling, both above the optimal range of 0.5%-1.0%. Incomplete fuel combustion by the ice resurfacer was the most likely source of elevated CO. CO poisonings in ice arenas can be prevented through regular maintenance of ice resurfacers, installation of CO detectors, and provision of adequate ventilation.

Consumption of locally caught fish provides health benefits but can be a route of exposure to methylmercury and other persistent environmental contaminants. Previous studies found that Asian women of childbearing age (WCBA) in the Milwaukee area have high levels of exposure through fish consumption but limited awareness of fish advisories. We conducted a focus group project to understand the influence of culture, attitudes, and beliefs on the fish consumption habits of Chinese, Hmong, and Karen WCBA who reside in the Milwaukee area to develop culturally appropriate educational materials. A total of 19 women aged 18-50 years identifying as Chinese, Hmong, or Karen were recruited. Three focus groups were held, each consisting of 6-7 participants from one ethnicity. Focus group transcripts were thematically analyzed and coded based on the integrated behavioral model. Nutritional benefits and availability were the most common reasons to eat locally caught fish. All participants were aware of risks associated with eating fish, yet few knew ways to mitigate risk and maximize benefits. Participants expressed interest in receiving health messages from trusted sources and recommended that messaging target families rather than just individuals. Participants who were confident in their self-efficacy expressed a greater likelihood of following health message guidelines. Results suggest providing culturally appropriate educational materials in preferred languages to Asian communities via local community organizations may increase self-efficacy and adherence to fish advisories. Future projects will evaluate the effectiveness of self-affirmation messaging among Asian WCBA and assess changes in fish consumption based on message content.
RESUMO
OBJECTIVES: Prevention methods for carbon monoxide (CO) poisoning in Wisconsin address occupational and nonoccupational exposures together, but differences between the settings could inform new approaches to preventing occupational CO poisonings. We described occupational CO poisonings in Wisconsin from July 1, 2018, through July 1, 2021, using surveillance data from the Wisconsin Electronic Disease Surveillance System and Wisconsin Poison Center. METHODS: We identified cases of CO poisoning from the Wisconsin Electronic Disease Surveillance System and Wisconsin Poison Center. Occupational CO poisonings were records where "workplace" was recorded as the location of exposure. We excluded records classified as suspect/not a case, those missing laboratory results or information on exposure source/location, and intentional poisonings. We compared characteristics between occupational and nonoccupational settings using odds ratios (ORs), and we estimated crude incidence rates of occupational exposures by occupation. RESULTS: We identified 614 cases of CO poisoning, of which 168 (27.4%) were occupational exposures. When compared with patients with nonoccupational exposures, patients with occupational exposures were more likely to be male (OR = 3.8; 95% CI, 2.4-6.1), Hispanic (OR = 2.4; 95% CI, 1.4-4.2), and younger (mean difference [SD] = 6.6 [20.9]). Several CO sources were significantly associated with occupational poisonings: forklifts (OR = 58.4; 95% CI, 13.9-246.1; P < .001), pressure sprayers (OR = 2.4; 95% CI, 1.3-4.4; P = .003), and other gasoline-powered tools (OR = 3.8; 95% CI, 2.3-6.3; P < .001). The natural resources, construction, and maintenance occupation group had the highest crude incidence rate-45.0 poisonings per 100 000 full-time equivalent employees. CONCLUSIONS: Incorporating data from the Wisconsin Poison Center improved data quality, but surveillance is limited by underreporting. Creating strategies to increase reporting would allow for a more comprehensive understanding of occupational CO poisoning.
RESUMO
Wastewater-based epidemiology (WBE) has been demonstrated for its great potential in tracking of coronavirus disease 2019 (COVID-19) transmission among populations despite some inherent methodological limitations. These include non-optimized sampling approaches and analytical methods; stability of viruses in sewer systems; partitioning/retention in biofilms; and the singular and inaccurate back-calculation step to predict the number of infected individuals in the community. Future research is expected to (1) standardize best practices in wastewater sampling, analysis and data reporting protocols for the sensitive and reproducible detection of viruses in wastewater; (2) understand the in-sewer viral stability and partitioning under the impacts of dynamic wastewater flow, properties, chemicals, biofilms and sediments; and (3) achieve smart wastewater surveillance with artificial intelligence and big data models. Further specific research is essential in the monitoring of other viral pathogens with pandemic potential and subcatchment applications to maximize the benefits of WBE beyond COVID-19.
RESUMO
BACKGROUND: This article describes the first Community Assessment for Public Health Emergency Response (CASPER) rapid needs assessment project to be conducted in Wisconsin. The project focused on extreme heat preparedness. METHODS: Fifteen teams conducted household surveys in 30 census blocks in the city of Milwaukee, Wisconsin. RESULTS: Survey results indicated that the majority of households were unaware of the location of a nearby cooling center. Although the vast majority of households reported some form of air conditioning in their house, over half felt too hot inside their home sometimes, most of the time, or always. DISCUSSION: The community partnerships ensured that this project was conducted with local partner input and that the data could be used to inform extreme heat response.

Introduction: Carbon monoxide (CO) is a colorless, odorless, and nonirritating gas. The most common exposures are from gas powered appliances such as furnaces, water heaters, stoves, and vehicles. To prevent poisoning, CO detectors with audible alarms were developed. This study aims to evaluate the effectiveness of CO detectors in reducing poisoning in Wisconsin.Methods: Records were queried from National Poison Data System for unintentional CO exposures that occurred in residences in Wisconsin during 2014-2016 (N = 703). After applying sample exclusion criteria, notes were abstracted for cases where CO detector use was mentioned (n = 408). Logistic regression analyses were used to assess the association between having a CO detector alarm and CO poisoning. Linear regression analyses were used to assess the relationship between having a CO detector alarm and poisoning severity.Results: In logistic models, odds of CO poisoning were 3.2 times higher (95% CI: 1.5, 6.9) among those who had no CO detector compared to those who had a CO detector that alarmed. In linear models, not having a CO detector was associated with a 0.34 point (95% CI: 0.17, 0.54) change in outcome severity score compared to having a CO detector that alarmed.Discussion: Individuals who were exposed to CO in the absence of a CO detector were more likely to be poisoned and to have more severe medical outcomes than those that had a CO detector that alarmed.

BACKGROUND: Perfluoroalkyl substances (PFAS) are a class of contaminants used in many industrial applications and consumer products. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects. OBJECTIVES: In this analysis we examine PFAS levels and their association with metabolic syndrome and its components, using a representative sample of the U.S. METHODS: Data on PFAS levels and metabolic syndrome components were collected from the 2007-2008, 2009-2010, 2011-2012, and 2013-2014 cycles of the National Health and Nutrition Examination Survey. Twelve different PFAS were measured in serum samples from participants. Logistic regression models were used to identify associations between metabolic syndrome, its individual components, and serum PFAS concentrations. RESULTS: Over one-third (37%) of participants met the definition for metabolic syndrome, with increased waist circumference and elevated glucose being the most commonly reported components. Seven PFAS were detected in at least 30% of participants and were examined in subsequent analyses (PFDA, PFOA, PFOS, PFHxS, MPAH, PFNA, PFUnDA). The PFAS with the highest concentrations was PFOS (median 8.4â¯ng/mL), followed by PFOA, PFHxS and PFNA. After adjusting for potential confounders, PFNA was associated with increased risk of metabolic syndrome and well as several individual components, while the highest levels of PFHxS were associated with elevated triglycerides. Other PFAS were associated with decreased risk of at least one outcome. CONCLUSIONS: Associations between PFAS and metabolic syndrome are inconsistent within and across studies. PFNA was consistently associated with increased risk for components of the syndrome, a finding that warrants further investigation.

BACKGROUND: Opioid overdoses and opioid-related fatalities have increased dramatically in Wisconsin over the past decade. The observed rise in morbidity and mortality parallels increased opioid prescribing and greater use of illicit drugs such as heroin. Increased availability of both prescription and illicit opioids may increase the risk of exposure and overdose among the pediatric population. METHODS: We examined demographics and temporal trends in opioid exposures among children aged 0-19 years using hospital encounter and Wisconsin Poison Control Center (WPC) data. Exposures were categorized by type of opioid. RESULTS: We identified 3,320 WPC calls and 2,725 hospital encounters involving opioids during 2002-2016. Within the hospital encounter data, the rate of opioid-involved exposures increased significantly in children aged 0-5 years and adolescents aged 13-19 years. The majority of opioid-related hospital encounters involved prescription opioids. However, the proportion of hospital encounters involving heroin increased significantly among 13-19 year olds from 2002-2016. Within WPC data, the proportion of calls involving tramadol increased among 0-5 year olds and 13-19 year olds. However, calls about opioid/acetaminophen combinations decreased significantly as a proportion of opioid exposures. DISCUSSION: These findings suggest the need for caregiver education regarding safe storage and disposal of prescription opioids to prevent unintentional or intentional exposure to these substances among young children and adolescents. Overdose rates among teens continue to rise and an increasing proportion are due to heroin; comprehensive treatment and prevention strategies targeting this demographic are needed.

INTRODUCTION: Carbon monoxide (CO) poisoning is responsible for over 450 deaths and 21,000 Emergency Department visits annually in the United States. In Wisconsin, multiple large-scale CO poisoning events have occurred in recent years. This analysis explores trends in CO exposure events in the state from 2006 through 2016. METHODS: Wisconsin Poison Center (WPC) CO exposure data from January 1, 2006 through December 31, 2016 was analyzed for trends over time. CO poisoning cases were classified using the Council of State and Territorial Epidemiologists case definition. RESULTS: During the study period, 3,703 persons were exposed to CO and 2,148 were poisoned. On average, 337 persons were exposed annually over this period, with an annual average of 195 suspected and probable poisoning cases per year, as reported to the WPC. Large-scale events ( ≥ 5 persons) accounted for 4.8% (n = 104) of all events. Using data extracted from WPC case notes for large-scale exposures, the most common source of exposure was furnaces or water heaters (20.2%; n = 21) followed by fire (8.7%; n = 9). CONCLUSIONS: Despite public health efforts to reduce CO exposures, CO poisoning continues to affect Wisconsin residents. Efforts to prevent large scale CO poisonings should focus on awareness of CO exposure within the home, as well as the risk in public or occupational settings. Moreover, these efforts should focus on improving the use of CO detectors in all settings to prevent exposure. The WPC can be used as a resource for clinicians in cases of CO exposure and poisoning.

INTRODUCTION: In 2016, 4,353 Wisconsin children under 6 years of age were identified with elevated blood lead levels (≥ 5 µg/dL). There is no safe level of lead in the human body; extensive research shows that children with blood lead levels < 5 µg/dL may still be at risk for adverse health effects including developmental delays. DISCUSSION: Physicians should follow current guidelines and consider factors such as the child's age, socioeconomic status, and housing situation when determining need for testing. In addition to Wisconsin's screening recommendations, federal requirements exist for testing Medicaidenrolled children. Under state statute, all blood lead test results and specified demographic information must be reported to the Wisconsin Childhood Lead Poisoning Prevention Program. To eliminate elevated blood lead levels, primary prevention is key. Physicians play an important role by educating parents, prospective parents, and caregivers about lead poisoning risks and prevention measures. Physicians are also vital in secondary prevention-mitigating the adverse effects in children already exposed to lead. Secondary prevention requires first identifying children with elevated blood lead levels through appropriate testing. Use of the Wisconsin Blood Lead Registry can alert providers about children with elevated blood lead levels and reduce duplicate testing. Recent surveillance data show current screening is inadequate; in 2015, only 32% of Medicaid-enrolled children received appropriate testing. Physicians should provide clinical management for children with elevated blood levels and their families. CONCLUSIONS: Physicians are a vital partner in preventing, identifying, and mitigating the effects of elevated blood lead levels for Wisconsin's children.

OBJECTIVES: The aim of the study was to describe mesothelioma occurrence in Wisconsin from 1997 to 2013 by usual industry and occupation (I&O), including occupations generally considered low risk. METHODS: Population-based rates and standardized incidence and mortality ratios were calculated. Two case-control analyses were designed to compare mesothelioma incidence and mortality in specific I&O groups with occurrence of (1) brain and central nervous system cancers and (2) other causes of death, using logistic regression. RESULTS: Mesothelioma incidence and mortality were elevated in Wisconsin (SIRadj = 1.20 [1.13 to 1.28]; SMRadj = 1.30 [1.22 to 1.38]). Certain industry (construction, manufacturing) and occupation (construction and extraction) groups were associated with increased odds of mesothelioma, with some evidence of increased risk among teachers. CONCLUSIONS: Forty years after the Occupational and Safety Health Act, mesothelioma incidence and mortality remain elevated in Wisconsin, with increased risk continuing for certain I&O groups.

OBJECTIVE: In March 2016, the state health departments of Wisconsin and Minnesota learned of three shipyard workers with blood lead levels (BLLs) more than 40âµg/dL. An investigation was conducted to determine the extent of and risk factors for the exposure. METHODS: We defined a case as an elevated BLL more than or equal to 5âµg/dL in a shipyard worker. Workers were interviewed regarding their symptoms and personal protective equipment (PPE) use. RESULTS: Of 357 workers, 65.0% had received more than or equal to 1 BLL test. Among tested workers, 171 (73.7%) had BLLmax more than or equal to 5âµg/dL. Workers who received respirator training or fit testing had a median BLLmax of 18.0âµg/dL, similar to the median BLLmax of workers who did not receive such training (22.6âµg/dL, Pâ=â0.20). CONCLUSIONS: Our findings emphasize the importance of adequate provision and use of PPE to prevent occupational lead exposure.

BACKGROUND: E-cigarettes are battery-powered devices that deliver nicotine and flavorings by aerosol and have been marketed in the United States since 2007. Because e-cigarettes have increased in popularity, toxicity potential from device misuse and malfunction also has increased. National data indicate that during 20102014, exposure calls to US poison control centers increased only 0.3% for conventional cigarette exposures, whereas calls increased 41.7% for e-cigarette exposures. METHODS: We characterized cigarette and e-cigarette exposure calls to the Wisconsin Poison Center January 1, 2010 through October 10, 2015. We compared cigarette and e-cigarette exposure calls by exposure year, demographic characteristics, caller site, exposure site, exposure route, exposure reason, medical outcome, management site, and level of care at a health care facility. RESULTS: During January 2010 to October 2015, a total of 98 e-cigarette exposure calls were reported, and annual exposure calls increased approximately 17-fold, from 2 to 35. During the same period, 671 single-exposure cigarette calls with stable annual call volumes were reported. E-cigarette exposure calls were associated with children aged ≤5 years (57/98, 58.2%) and adults aged ≥20 years (30/98, 30.6%). Cigarette exposure calls predominated among children aged ≤5 years (643/671, 95.8%). CONCLUSION: The frequency of e-cigarette exposure calls to the Wisconsin Poison Center has increased and is highest among children aged ≤5 years and adults. Strategies are warranted to prevent future poisonings from these devices, including nicotine warning labels and public advisories to keep e-cigarettes away from children.

BACKGROUND: Heroin abuse has increased substantially during the past decade in the United States. This study describes trends and demographic shifts of heroin overdoses and heroin-related fatalities in Wisconsin and contrasts these with prescription opioid overdoses. METHODS: This study was cross-sectional using databases of emergency department (ED) visits, hospital admissions, and death certificates in Wisconsin, United States, during 2003-2012. Cases were Wisconsin residents treated for heroin or prescription opioid overdose, and residents who died of heroin-related drug poisoning. Primary measurements were rates over time and by geographic region, and rates and rate ratios for selected demographic characteristics. RESULTS: During 2003-2012, age-adjusted rates of heroin overdoses treated in EDs increased from 1.0 to 7.9/100,000 persons; hospitalized heroin overdoses increased from 0.7 to 3.5/100,000. Whites accounted for 68% of hospitalized heroin overdoses during 2003-2007 but 80% during 2008-2012. Heroin-related deaths were predominantly among urban residents; however, rural fatalities accounted for zero deaths in 2003 but 31 (17%) deaths in 2012. Among patients aged 18-34 years, those hospitalized with heroin overdose were more often men (73.0% versus 54.9%), uninsured (44.2% versus 29.9%), and urban (84.3% versus 73.2%) than those with prescription opioid overdose. Rates of ED visits for heroin overdose in this age group exceeded rates for prescription opioid overdose in 2012 (26.1/100,000 versus 12.6/100,000 persons, respectively). CONCLUSIONS: An epidemic of heroin abuse is characterized by demographic shifts toward whites and rural residents. Rates of heroin overdose in younger persons now exceed rates of prescription opioid overdose.
