まとめ
民間投資による病院の買収により 患者への被害が増加し 転倒や感染が増加しました これらの発見は,医療の質と患者の安全に対する民間資本の影響について懸念を喚起しています.
科学分野:
- 医療サービス研究
- 健康 経済
- 患者の安全
背景:
- 民間資本 (PE) の所有が米国の病院の臨床品質と患者の結果に与える影響は十分に理解されていません.
- 以前の研究では,病院で発生した有害事象や患者のアウトカムに対する PE 獲得の効果を全面的に評価していなかった.
研究 の 目的:
- 米国病院の民間資本買収と病院で発生した有害事象や入院結果の変化との関連を調査する.
- 医療の質と患者の安全性についての洞察を提供すること.
主な方法:
- 2009年から2019年のメディケア・パートAの請求データを用いた比較研究です.
- イベント研究,差異の設計を使用して,PEを取得した51の病院と259の対照病院を比較しました.
- 患者と病院の特徴に合わせて 病院で得られた疾患や 患者の組み合わせや 死亡率や再入院などのアウトカムを評価します
主要な成果:
- PEの獲得は,下落の27.3%の増加と,中央線に関連した血流感染症の37.7%の増加を含む,病院で獲得された状態の25.4%の増加と関連付けられました.
- 手術部位の感染症は 手術の容量が減ったにもかかわらず PE病院で倍増しました
- PE病院の入院期間は短く 退院後の転院は多く 退院後30日後に持続しなかった入院死亡率はわずかに減少した.
結論:
- 病院の民間資本の獲得は 病院による有害事象,特に転倒や感染症の 増加と関連しています.
- 患者の人口動態の変化と移送の増加は,短期的な死亡率の変化を部分的に説明する可能性がある.
- これらの結果は,医療の提供と患者の安全に対する民間資本の影響に関する重大な懸念を強調しています.
