To analyze the long-term trends in pollen counts and asthma-related emergency department visits (AREDV) in adult and pediatric populations in the Bronx.
Daily values of adult and pediatric AREDV were retrospectively obtained from three major Bronx hospitals using ICD-10 codes and pollen counts were obtained from the Armonk station from 2001-2020. Wilcoxon Ranked Sum was applied to compare median values, while Spearman correlation was employed to examine the association between these variables, for both decades and each season.
The median value of pediatric AREDV increased by 200% from the 1st to 2nd decade ( < 0.001) and AREDV peak shifted from predominantly the spring season in the 1st decade to the fall and winter seasons in the 2nd decade. Seasonal patterns were consistent over 20 years with summer AREDV lower than all other seasons (9 vs. 17 per day) ( < 0.001). Spring tree pollen peaks were correlated with AREDV peaks (rho = 0.34) ( < 0.001). Tree pollen exceeding 100 grains/m corresponded to a median of 19.0 AREDVs while all other tree pollen (0 - 99 grains/m) corresponded to a median of 15.0 AREDVs ( < 0.001). AREDVs sharply declined in 2020, coinciding with the emergence of COVID-19.
Pollen and AREDVs peak earlier in the spring and are more strongly interconnected, while asthma rates among children are rapidly rising, particularly in the fall and winter. These findings can advise targeted awareness campaigns for better management of asthma related morbidity.
分析布朗克斯区成人和儿科人群花粉计数和与哮喘相关的急诊就诊（AREDV）的长期趋势。
使用 ICD-10 代码从三家主要的布朗克斯医院回顾性获得每日成人和儿科 AREDV 值，花粉计数则从 2001-2020 年的阿蒙克站获得。Wilcoxon 秩和检验用于比较中位数，Spearman 相关系数用于检验这些变量之间的相关性，包括两个十年和每个季节。
儿科 AREDV 的中位数在第一个十年到第二个十年增加了 200%（<0.001），并且 AREDV 峰值从第一个十年的主要春季季节转移到第二个十年的秋季和冬季季节。20 年来，季节性模式一直保持一致，夏季 AREDV 低于其他所有季节（每天 9 次比 17 次）（<0.001）。春季树木花粉峰值与 AREDV 峰值相关（rho=0.34）（<0.001）。树木花粉超过 100 粒/米时，中位数为 19.0 次 AREDV，而所有其他树木花粉（0-99 粒/米）的中位数为 15.0 次 AREDV（<0.001）。AREDV 在 2020 年急剧下降，恰逢 COVID-19 的出现。
花粉和 AREDV 在春季更早达到峰值，并且相互关联更紧密，而儿童哮喘发病率迅速上升，特别是在秋季和冬季。这些发现可以为更好地管理与哮喘相关的发病率提供针对性的宣传活动建议。
