RESUMO
Disaster epidemiology (i.e., applied epidemiology in disaster settings) presents a source of reliable and actionable information for decision-makers and stakeholders in the disaster management cycle. However, epidemiological methods have yet to be routinely integrated into disaster response and fully communicated to response leaders. We present a framework consisting of rapid needs assessments, health surveillance, tracking and registries, and epidemiological investigations, including risk factor and health outcome studies and evaluation of interventions, which can be practiced throughout the cycle. Applying each method can result in actionable information for planners and decision-makers responsible for preparedness, response, and recovery. Disaster epidemiology, once integrated into the disaster management cycle, can provide the evidence base to inform and enhance response capability within the public health infrastructure.

Public health surveillance and epidemiology are the foundations for disease prevention because they provide the factual basis from which agencies can set priorities, plan programs, and take actions to protect the public's health. Surveillance for noninfectious diseases associated with exposure to agents in the environment like lead and pesticides has been a function of state health departments for more than 3 decades, but many state programs do not have adequate funding or staff for this function. Following the efforts to identify core public health epidemiology functions in chronic diseases, injury, and occupational health and safety, a workgroup of public health environmental epidemiologists operating within the organizational structure of the Council of State and Territorial Epidemiologists has defined the essential core functions of noninfectious disease environmental epidemiology that should be present in every state health department and additional functions of a comprehensive program. These functions are described in terms of the "10 Essential Environmental Public Health Services" and their associated performance standards. Application of these consensus core and expanded functions should help state and large metropolitan health departments allocate resources and prioritize activities of their environmental epidemiologists, thus improving the delivery of environmental health services to the public.

BACKGROUND: Prior assessments of public health readiness had identified gaps in radiation preparedness. In recent years, preparedness planning has involved an "all-hazards" approach. Current assessment of the national status related to radiation public health emergency preparedness capabilities at the state and local health department levels was needed. METHODS: A survey of state health departments related to radiation readiness was undertaken in 2010 by the Council of State and Territorial Epidemiologists (CSTE). States with nuclear power plants were instructed to consider their responses exclusive of capabilities and resources related to the plants given that the emergency response plans for nuclear power plants are specific and unique. RESULTS: Thirty-eight (76%) state health departments responded to the survey, including 26 of the 31 states with nuclear power plants. Specific strengths noted at the state level included that the majority of states had a written radiation response plan and most plans include a detailed section for communications issues during a radiation emergency. In addition, more than half of the states indicated that their relationship with federal partners is sufficient to provide resources for radiation emergencies, indicating the importance states placed on federal resources and expertise. Specific weaknesses are discussed and include that most states had completed little to no planning for public health surveillance to assess potential human health impacts of a radiation event; less than half had written plans to address exposure assessment, environmental sampling, human specimen collection and analysis, and human health assessment. Few reported having sufficient resources to do public health surveillance, radiation exposure assessment, laboratory functions and other capabilities. DISCUSSION: Levels of planning, resources and partnerships varied among states, those with nuclear power plants were better prepared. Gaps were evident in all states; however and additional training and resources are needed to ensure adequate levels of preparedness. CONCLUSION: Overall results of this assessment indicate that in most measures of public health capacity and capability, states are poorly prepared to adequately respond to a major radiation emergency event. Specific recommendations are noted in the discussion.

OBJECTIVE: Pyrethrin and pyrethroid insecticides are commonly applied in homes and businesses and on some agricultural crops. This research used a two-state regional approach to analyze reports of acute pesticide poisonings due to pyrethrin and pyrethroid insecticides. METHODS: The Washington State Department of Health and the Oregon Public Health Division collected pesticide poisoning surveillance data from 2001 through 2005. Cases were included if they involved exposure to at least one pyrethrin or pyrethroid insecticide. Descriptive statistics were calculated; differences between categories were assessed using Chi-square analysis. RESULTS: A total of 407 cases fit our definition. Overall, the rate of poisoning in Oregon was significantly higher than in Washington (incidence rate ratio 1.70, 95% confidence interval 1.40, 2.07), and rates for both states generally increased during the time period. For both states, most exposures resulted in low severity illnesses (92%), and most were classified as possible cases (73%). Only about one-fourth of cases were related to a person's work. The most common category of clinical signs and symptoms of illness was respiratory (52% of cases), followed by neurological (40% of cases). Exposure route was predominantly inhalation; there was no association between route and case severity. There was a significant association between illness severity and losing time from work or regular activities (p<0.0001). CONCLUSIONS: Although the majority of pyrethrin and pyrethroid poisoning cases were low in severity, adverse reactions have occurred, as transpired in Oregon in 2005. Regional analysis has the potential to improve the surveillance system and provide unique opportunities for targeting preventive interventions.

Trichloroethylene (TCE), a common groundwater contaminant, was found at high levels at an Oregon work site in 1998. According to a recent report released by the National Research Council, "the evidence on carcinogenic risk and other health hazards from exposure to trichloroethylene has strengthened since 2001." A convenience sample of 13 former workers from the Oregon work site was recruited for a series of focus groups. Information obtained on plant processes, safety procedures, attitudes regarding medical record access, and opinions about proxy accuracy was subjected to qualitative content analysis. Workers recalled few safety policies and no training or support for control of safety. Most thought co-workers and family members would be the best source of proxy exposure information and favored granting access to medical records. Job-role mobility confirmed the importance of using a job or task exposure matrix. Information obtained will be used in development of an exposure assessment interview tool.

OBJECTIVE: Evidence demonstrates that occupational exposures are causally linked with chronic obstructive pulmonary disease (COPD). This case-control study evaluated the association between occupational exposures and prevalent COPD based on lifetime occupational history. METHODS: Cases (n = 388) aged 45 years and older with COPD were compared with controls (n = 356), frequency matched on age, sex, and cigarette smoking history. Odds ratios for exposure to each of eight occupational hazard categories and three composite measures of exposure were computed using logistic regression. RESULTSOccupational exposures most strongly associated with COPD were diesel exhaust, irritant gases and vapors, mineral dust, and metal dust. The composite measures describing aggregate exposure to gases, vapors, solvents, or sensitizers (GVSS) and aggregate exposure to dust, GVSS, or diesel exhaust were also associated with COPD. In the small group of never-smokers, a similar pattern was evident. CONCLUSION: These population-based findings add to the literature linking occupational exposures to COPD.

OBJECTIVE: The objective of this study was to evaluate work-related asthma among health maintenance organization (HMO) members. Recent reports suggest that the incidence of work-related asthma may be much higher than Sentinel Event Notification Systems for Occupational Risks (SENSOR) data estimate. METHODS: Using the HMO's electronic medical record, we identified 1,747 persons with evidence of new or recurrent asthma. Interviews with 352 of them elicited information about workplace exposures, symptoms, and home environment. Industrial hygienists rated the potential asthmagenicity of the respondents' work environments. RESULTS: Based on the industrial hygienist ratings and self-reported work-relatedness of asthma symptoms, we classified 33% of those interviewed as having potentially work-related asthma, suggesting an overall work-related asthma incidence/recurrence rate of 28 cases per 10,000. CONCLUSIONS: The contribution of occupation to the occurrence of adult onset asthma may be much higher than typically suggested in the literature.

OBJECTIVE: The development of a reliable asthma registry is an important first step for conducting population-based asthma disease management. This study developed a computerized algorithm for defining prevalent asthma, identified operational difficulties, and summarized data on asthma prevalence in the study population. STUDY DESIGN AND SETTING: As part of a study of the incidence of occupational asthma, we used the electronic databases of a large health maintenance organization to develop a computerized algorithm for defining prevalent asthma and validated it against chart review. The predictive values of eight health care utilization profiles were validated by chart review to establish the algorithm. RESULTS: The 1-year treated prevalence of asthma was 4.1% among members aged 15-55; the pharmacy database identified 61% of cases, and the outpatient care database 66%. Extending the outpatient care window from 1 year to 2 years increased estimated prevalence to 5.3%, with 81% now found in the outpatient care database. CONCLUSION: This analysis illustrates the benefit of using multiple databases for more accurate enumeration of cases and the impact of extending the search in time. These results are useful for researchers who can use such databases in selecting algorithms to define and identify asthma for their own purposes.
