まとめ
イタリアにおける償還済みHIV曝露前予防(PrEP)は、利用率またはユーザーの多様性を有意に増加させなかった。この重要なHIV予防ツールへの公平なアクセスを確保するには、追加の戦略が必要である。
科学分野:
- 公衆衛生、HIV予防、医療サービス研究
- Public Health; HIV Prevention; Health Services Research
背景:
- HIV曝露前予防(PrEP)の償還は、イタリアにおけるその採用を強化し、ユーザーベースを拡大することが期待されていた。本研究では、地域ベースのサービス設定における償還前後のPrEP開始パターンの変化を調査する。
- Reimbursement of HIV pre-exposure prophylaxis (PrEP) was anticipated to enhance its adoption and broaden the user base in Italy. This study examines shifts in PrEP initiation patterns before and after its reimbursement within a community-based service setting.
研究 の 目的:
- PrEP償還が開始パターンとユーザーの人口統計に与える影響を評価すること。償還されたPrEPの利用可能性に続くPrEPの利用率とユーザーの多様化の変化を評価すること。
- To evaluate the impact of PrEP reimbursement on initiation patterns and user demographics. To assess changes in PrEP uptake and user diversification following the availability of reimbursed PrEP.
主な方法:
- 単施設後ろ向きコホート研究では、2017年9月から2024年10月の間にPrEPを開始した1394人を分析した。参加者は、償還前(2023年6月以前)および償還後グループに分けられた。単群中断時系列分析(ITSA)を区分線形回帰で用いて、月次開始傾向を分析した。
- A monocentric retrospective cohort study analyzed 1394 individuals initiating PrEP between September 2017 and October 2024. Participants were divided into pre-reimbursement (before June 2023) and post-reimbursement groups. Single-group interrupted time series analysis (ITSA) with segmented linear regression was employed to analyze monthly initiation trends.
主要な成果:
- 研究には、PrEP償還前後に1019人および375人が含まれた。償還後、白人の割合が高く、生涯の性的パートナーが少ないなど、人口統計学的な変化がわずかに見られた。ITSAは、COVID-19のロックダウン後にPrEP開始の大幅な増加を明らかにしたが、PrEP償還は有意な即時の増加を示さず、その後の開始の減少傾向を示した。
- The study included 1019 individuals before and 375 after PrEP reimbursement. Post-reimbursement, there were modest demographic shifts, including a higher proportion of white individuals and fewer lifetime sexual partners. ITSA revealed a significant increase in PrEP initiations post-COVID-19 lockdown, but PrEP reimbursement showed no significant immediate increase and a subsequent negative trend in initiation.
結論:
- この地域ベースの設定における償還PrEPは、利用率またはユーザーの多様性の実質的な増加をもたらさなかった。調査結果は、医薬品の償還だけではPrEPへの公平なアクセスを改善するには不十分である可能性を示唆している。PrEPのアクセスと多様な集団への到達を強化するには、さらなる実施戦略が必要である。
- Reimbursed PrEP in this community-based setting did not lead to a substantial rise in uptake or user diversity. Findings suggest that drug reimbursement alone may be insufficient to improve equitable access to PrEP. Further implementation strategies are necessary to enhance PrEP accessibility and reach diverse populations.
