Snippet: To study the possible relationship between air pollution and number of hospital admissions, the highest level of pollution, expressed by mean weekly values (Catalonian Air Quality Index) was used. Over the year, the mean score obtained on the Catalonian Air Quality Index scale was 42.5±10.2, which, according to the scale detailed in the methods, corresponded to an acceptable air quality.

Document: To study the possible relationship between air pollution and number of hospital admissions, the highest level of pollution, expressed by mean weekly values (Catalonian Air Quality Index) was used. Over the year, the mean score obtained on the Catalonian Air Quality Index scale was 42.5±10.2, which, according to the scale detailed in the methods, corresponded to an acceptable air quality. When stratifying according to the air quality scale, 858 (8.8%) admissions occurred in weeks in which air quality was considered low (more pollution), 6,481 (66.1%) during weeks when it was estimated as acceptable, and 2,645 (26.1%) during periods when it was rated as satisfactory (less pollution). Weeks of pollution coincided with higher temperatures, although no significant differences were found between air pollution and number of hospital admissions (P=0.887).
