まとめ
50歳以上の米国人における呼吸器同胞性ウイルス (RSV) 検査は,増加率にもかかわらず,依然として稀です. 検査の確率は介護施設や医療機関によって変化し,RSV症例の検出不足を強調した.
科学分野:
- 流行病学
- 公衆衛生
- 感染症
背景:
- 呼吸器同胞ウイルス (RSV) は,50歳以上の成人の急性呼吸器疾患 (ARI) の重要な原因です.
- RSVの診断が不十分であるのは,検査と測定の感度が限られているためです.
- 検査パターンを理解することは,RSVの流行病学と病気の負担を評価するために極めて重要です.
研究 の 目的:
- 50歳以上の米国人の呼吸器ウイルス検査パターンを調査する.
- この集団におけるRSV検査に関連する特徴を特定する.
主な方法:
- 医療従事者の診察を受けた50歳以上の成人の電子医療記録 (2015年-2023年) の遡及分析
- RSVおよび他の呼吸器ウイルスの検査パーセントの計算,流行病学年およびケア設定によって層分化.
- RSV検査の確率に関連する要因を評価するための多変量ロジスティック回帰
主要な成果:
- RSV検査は,2200万件以上のARIエピソードのうち2. 4%のみで行われました.
- RSV検査率は時間とともに1.3%から5.9%に増加したが,インフルエンザとSARS-CoV-2検査よりも低いままだった.
- 入院患者および緊急治療室では,門診患者と比較してRSV検査率が高かった.
- 集中治療施設 (入院,ED) と医療機関では,RSV検査の確率が著しく高まった.
結論:
- RSV検査の頻度は,ケア環境と医療組織の強さに大きく異なります.
- 増加傾向にもかかわらず,RSV検査は50歳以上の米国人ではほとんど行われていません.
- RSV症例の検出不足は,病気の負担と予防戦略を評価する際に考慮する必要があります.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
