“…This dataset could be used to further investigate the effects of multiple encounters, health insurance, and seasonality on pediatric asthma. Asthma surveillance systems should also be expanded to include survey and environmental data to provide a more comprehensive picture of asthma (18,24,25). This study demonstrates how existing datasets can be integrated to enhance the surveillance of pediatric asthma and provide greater insight into the burden of asthma.…”

We examined the race/ethnicity variation in the risk of hospitalization among children seen in the emergency department (ED) for asthma. ED and hospitalization records for children 1 to 19 years of age in New Jersey for 2004 and 2005 were linked. The dataset identified 47,548 ED and hospitalizations among 37,216 children. ED and hospitalization rates indicated persistent disparities in pediatric asthma. ED admission rates were similar across race/ethnic groups, suggesting similar management of pediatric asthma patients once they are seen in the ED. Integrating existing ED and hospitalization records will enhance asthma surveillance and the targeting of interventions to reduce race/ethnicity disparities.

“…SENSOR data cannot provide estimates of the true incidence or prevalence of WRA. Although WRA is a reportable condition in all four states, cases of WRA are both under-diagnosed and under-reported [Milton et al, 1998;Enright et al, 1999;Deprez et al, 2002]. Some patients with symptoms of asthma are not adequately diagnosed or the association of symptoms with workplace exposure is not recognized.…”

“…[15][16][17] The high frequency of children having asthma-related ED visits necessitates the inclusion of ED billing data in any comprehensive surveillance system. However, as mentioned previously, only a limited number of states have access to ED billing data, let alone the capacity to integrate that data into a true state-level asthma surveillance system.…”

“…The lack of a comprehensive asthma surveillance system, either at the state or federal level, has been identified as a major shortfall in the current public health approach to asthma. 1,[15][16][17] Asthma-related ED visits represent a large portion of asthma morbidity for which data are not widely available at the state level; currently, only ϳ20 states have access to ED encounter data. 18 Surveillance of ED pediatric asthma-related visits generated from already existing data sources such as billing data 19 can be used to characterize patients with asthma in terms of their demographic profile, date and time of presentation, geographic location (ie, zip code of residence), hospital admission rates, repeat visit rates, payer source (ie, insurance status), and direct medical costs.…”

Using Billing Data to Describe Patterns in Asthma-Related Emergency Department Visits in Children

OBJECTIVES. To describe the development and evaluation of a pilot emergency department (ED)-based asthma surveillance system for childhood asthma visits based on billing data and to illustrate how the data can be used to document trends and patterns in ED visits for asthma in children.METHODS. During 2001 and 2002, aggregate reports based on ED billing data from 3 hospitals in western Michigan were obtained from a single physician billing company. Data were tabulated and graphed to show trends in the monthly number of ED visits for asthma in children. Comparisons were made by age, gender, and site. We evaluated the system by using established guidelines.RESULTS. The data illustrated strong seasonal trends, as well as marked differences in ED use according to age and gender. The total numbers of asthma ED visits were remarkably similar between the 2 years evaluated; however, the timing and duration of the seasonal peaks differed. Our evaluation of the system found that it met many of the characteristics that define successful surveillance systems, including simplicity, flexibility, acceptability, sensitivity and positive predictive value, timeliness, and stability. However, the surveillance system's representativeness was limited by the inability to calculate valid population-based ED-visit rates. Despite this limitation, the data provided useful information by documenting the burden and demographic profile of children who use the ED for asthma care and in identifying seasonal and time-related trends.CONCLUSIONS. We were able to successfully implement a pilot ED-based surveillance system for childhood asthma visits by using billing data. This system promotes the understanding of the burden of asthma among children visiting the ED. The development of an ED-based surveillance system for childhood asthma visits using billing data is recommended, particularly when there is a desire to understand the characteristics of children with asthma who use the ED and/or a need to understand the impact of local asthma quality-improvement programs. A STHMA IS ONE of the most common reasons for presentation to emergency departments (EDs), and this chronic disease places a heavy but potentially preventable burden on the US health care system. 1-3 Children Յ14 years of age make ϳ600 000 ED visits for asthma every year in the United States, and the number of ED visits increased by 14% during the 1990s. 1 Between 10% and 30% of ED visits for asthma are repeat visits, and frequent ED use is associated with greater asthma severity and/or poor management, as well as poverty, ethnicity, and urban residence. [4][5][6][7] The current high level of interest concerning asthma stems from several features including the increase in asthma prevalence and mortality observed over recent decades, 8,9 the large costs involved, 10 the disproportionate effect on minority populations, 11 the concern about possible environmental causes, and the belief that the application of current clinical guidelines should result in better asthma control. 12 ...

Development of a Prototype System for Statewide Asthma Surveillance

Abstract: Databases were useful for estimating asthma burden and identifying service needs as well as high-risk groups. They were less useful in estimating severity or in identifying environmental risks.
