まとめ
社会的に脆弱な地域のメディケイド受給者は プライマリケアへのアクセスが低くなっています 社会的脆弱性指数 (SVI) は,これらの格差を特定し,連邦資格のある保健センター (FQHC) の支援を増やす必要性を強調しています.
科学分野:
- 医療サービス研究
- 健康の社会経済的決定因子
- 健康に関する公平性
背景:
- 貧困の集中は,恵まれない地域社会での医療へのアクセスを制限しています.
- 地域レベルでの社会経済指標は,医療資源の分配に対処するためにますます使用されています.
- 社会経済指標と初等医療へのアクセスとの関連は まだ十分に研究されていない.
研究 の 目的:
- メディケイドのプライマリーケア利用と 貧困/多面的な不利な状況との関係を調査する.
- 社会的な脆弱性指数 (SVI) の有用性を評価し,初等医療へのアクセス格差を特定する.
- 格差を特定するためにSVIと所得に基づく貧困率を比較する.
主な方法:
- 2019年トランスフォーメッド・メディケイド統計情報システムデータを用いた横断的な研究.
- メディケイド受給者 (65歳未満) の初等医療訪問 (連邦認定医療センターを含む) の分析.
- 個人の人口統計,健康状態,郵便番号レベルのSVIデシールと貧困率を制御する回帰分析.
主要な成果:
- 34,800万人の受益者の半数以上が 社会的に最も脆弱な20パーセントの郵便番号に 住んでいました
- 最も脆弱な地域 (SVI 10分位) の受益者は,初等医療訪問の割合が低い (FQHCを除いて8.9パーセント減少).
- FQHC訪問を含めると,格差が軽減され (4. 7パーセント減少),FQHCの使用は脆弱な地域では高かった (5. 9パーセント増加).
結論:
- メディケイド政策は,SVIのような多次元的な手段を用いて,地理的差異に対処すべきです.
- SVIは,適切な医療へのアクセスを妨げている地域を効果的に特定します.
- FQHCへの投資の増加は,医療へのアクセスにおける地理的不平等を緩和するために不可欠です.
