Recent epidemiologic surveys indicate a rising prevalence of asthma morbidity and mortality. In the United States there is concern about clusters of patients in large metropolitan areas since these suggest that "urban factors" may be contributing to a change in the natural history of asthma. We examined asthma initiated admissions from the emergency room (ER) of Mount Sinai Hospital a 1071 bed hospital in upper Manhattan, over the period of 1/1/90 through 12/31/90. Data was retrieved through the Hospital's Medical Records Department and included information on demographics (age, race, sex, payment system, admission date, length of stay and zip code). Additionally information on daily levels of air pollution for New York City was obtained from the New York State Department of Environmental Conservation (S02, N02, Ozone, Coefficient of haze) from the 22 stations in the New York Metropolitan area. There were 763 patients admitted for asthma attacks through the ER for a total of 1156 admissions during the period studied: 500 patients (F=221, M=279) were pediatric (< 20 yrs) and accounted for 780 admissions: 263 (F=196,M=67) were adult (>/= 20) accounting tor a total of 376 admissions. The mean length of stay for pediatric patients was 3.5 days (range 1-29) and for adults the mean length of stay was 7.3 days (range 1-246). Patients came from a total of 96 zip code areas. However, only 21 of these zip code areas individually accounted for more than 10 patients (primarily from upper Manhattan and the South Bronx). The mean length of stay for patients coming from these areas was 4.1 +/- 1 days and the average number of admissions per patient was 1.3 +/- 0.3. Four of these 21 zip codes exhibited high average admission rates per patient (1.6 to 2.3). The distribution of length of stay times did not vary appreciably by zip code. There were no correlations between number of admissions per patient and age or sex. We suggest that geographic factors may account for some of the variations found in the number of hospitalizations per asthmatic patients seen in this urban area.
