まとめ
医療従事者は,職業上のリスクに類似した,偶発的なヒト免疫不全ウイルス (HIV) 曝露のために,暴露後の予防療法 (PEP) を推奨することができます. 継続的または低リスクの露出については,リスク軽減プログラムが推奨されます.
科学分野:
- 公衆衛生は公衆衛生である.
- 感染症 感染症は感染症です.
- 抗ウイルス療法による抗ウイルス治療
背景:
- 最近の抗ウイルス治療の進歩とCDCのガイドラインは,医療従事者の暴露後の予防 (PEP) を促進しています.
- 医療従事者は,性的接触および注射薬物使用によるヒト免疫不全ウイルス (HIV) 曝露に関するPEPに関する問い合わせの増加に直面しています.
研究 の 目的:
- 非職業的なHIV被曝に対するPEPの推奨の適切性を評価する.
- 伝播リスクと局所的なHIV感染率に基づいて,PEPの決定について患者に助言する臨床医を指導する.
主な方法:
- 職業上のPEPの推奨から,乱発的な性的および注射薬物使用の露出にデータを抽出する.
- 異なる被曝タイプに対するHIV感染確率の評価.
- 情報に基づいた患者カウンセリングのための地元のHIVの血清発生率データを考慮する.
主要な成果:
- 偶発的な性的または注射薬物曝露は,職業上の皮膚経由的曝露に匹敵する伝染リスクを持ち,PEPが適切である可能性があることを示唆しています.
- 継続的または低リスクのエクスポージャーは,PEPよりもむしろリスク削減プログラムへの紹介を正当化します.
- 地元のデータに基づいた臨床医の判断は,PEPに関する患者の意思決定に不可欠です.
結論:
- PEPは,職業指針を反映した,散発的,より高いリスクの非職業的なHIV被曝のために考慮することができます.
- リスク軽減戦略は,継続的または低リスクの露出を有する個人にとって極めて重要です.
- PEPの標的化された公衆衛生介入は,予防的治療の範囲の制限のため,高流行地域に焦点を当てるべきである.

Ethics in Research
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Transmission-based Precautions I: Contact, Enteric, and Droplets
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Ethics and Bioethics
Ethics is a philosophical study of moral actions. Ethics attempts to determine what is valuable for individuals and society. It examines the rational justification of moral judgments and analyzes what is morally just, fair, and right. Bioethics is a sub-discipline of applied ethics that analyzes the philosophical, social, and legal issues in life sciences and medicine. Ethical theories serve as a foundation for decision-making and represent the viewpoints from which people seek direction. They...
