まとめ
COVID-19後の小児喘息入院はパンデミック前のレベルに戻った。しかし、平均在院日数(LOS)は減少し、潜在的に重症度が低下した可能性を示唆しており、医療費の削減につながる可能性がある。
科学分野:
- 小児呼吸器科;疫学;感染症
背景:
- ウイルス性疾患は小児喘息の増悪を一般的に引き起こし、インフルエンザシーズン中に高い入院率につながる。; 以前の研究では、COVID-19パンデミック中の喘息入院の減少と、それに伴う患者の重症度の増加が示唆されていた。; 小児喘息入院傾向に対するCOVID-19パンデミックの長期的な影響は、さらなる調査が必要である。
研究 の 目的:
- 初期のCOVID-19アウトブレイクから1年後の小児喘息入院および重症度の傾向を分析する。; パンデミック前、パンデミック中、パンデミック後の期間の入院データを比較する。; 喘息重症度の代理指標としての在院日数(LOS)に影響を与える要因を特定する。
主な方法:
- ブロンクス子供病院における小児喘息入院を比較するレトロスペクティブコホート研究。; 2019-2020年(パンデミック前)、2020-2021年(COVID-19)、2021-2022年(COVID-19後)の3つのコホートにおける10月から5月までのデータを収集。; 在院日数(LOS)を喘息重症度の近似値として利用し、コホートを比較するために統計分析を実施。
主要な成果:
- COVID-19後のコホート(318人)の総入院数はパンデミック前のレベル(320人)に近づき、COVID-19コホート(112人)よりも有意に高かった。; 平均LOSはパンデミック前の2.4日からCOVID-19後では2.0日に減少した(P = .0004)。; COVID-19コホートは、硫酸マグネシウムおよび集中治療を受ける可能性が増加した(P = .02、P = .0007)。
結論:
- 小児喘息入院はパンデミック前の頻度に戻った。; COVID-19後の平均在院日数の減少は、喘息重症度の低下または管理の変化の可能性を示唆している。; 減少したLOSに寄与する要因に関するさらなる研究は、小児喘息に関連する医療費を削減するための戦略に情報を提供する可能性がある。

Asthma: Pathogenesis and Management
1.5K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
