まとめ
行動科学に基づく手紙は,アクセス困難の住民の間でCOVID-19ワクチンの接種率を31.9%大幅に増加させた. これらの信頼性の高いコミュニケーションは 他の方法が失敗したときに 効果的に個人を巻き込み 公衆衛生の成果を向上させました
科学分野:
- 公衆衛生
- 健康に関する情報
- 行動科学
背景:
- イギリスのCOVID-19ワクチン接種プログラムは2021年2月までに全国的に最低のワクチン接種率を示した8つのノースウエストロンドンの臨床委任グループ (CCG) とともに,課題に直面した.
- この研究は,従来の手段で接触するのが難しい住民のワクチン接種率を改善することに焦点を当てました.
研究 の 目的:
- 行動科学情報 (BI) の有効性を評価し,COVID-19のワクチン接種率を高める.
- ロンドンの非接触者集団のワクチン接種へのBIの影響を評価する.
主な方法:
- 差異分析を用いた準実験的設計が採用された.
- セントラル・ロンドン・CCG (介入) のワクチン接種されず,接触できない住民は3つの対照CCGと比較して,BIの手紙を受け取った.
- ワクチン接種率の変化は,民族,年齢,性別,多重欠乏症指数 (IMD) の五分位数を含む共変数で調整された.
主要な成果:
- 介入CCGでは,ワクチン接種率が31. 9%増加した (p< 0. 0001).
- 最も顕著な増加は,最も貧乏な五分位 (IMD五分位) で,4. 1%の変化 (p< 0. 0001) であった.
- 混合的または複数の民族の住民はワクチン接種の可能性が低いことを示した (- 4. 1%,p< 0. 0001).
結論:
- 行動科学に基づいた手紙は 予防接種の普及を促進する費用対効果の高い信頼性の高い方法です
- このBIの手紙は他のコミュニケーション戦略に反応しない住民を成功させました.
- この研究は,医療介入の有効性におけるサブグループの違いを考慮する必要性を強調しています.
