まとめ
電子医療記録のデータは,クレームデータの傾向とは対照的に,安定したセプシスの発生率と死亡率を示しています. これは,正確なセプシス監視と患者のアウトカムを理解するための臨床データの重要性を強調しています.
科学分野:
- クリティカル ケア 医療
- 医療情報学
- 流行病学について
背景:
- クレームに基づく分析は,セプシスの発生率の増加と死亡率の減少を示唆しています.
- しかし,クレームのデータは臨床的信頼性が欠けており,コーディングの変更によって影響を受けることがあります.
研究 の 目的:
- 詳細な電子医療記録 (EHR) の臨床データを用いて,米国におけるセプシスの発生率と傾向を推定する.
- EHRベースの推定値と伝統的な請求に基づく推定値を比較する.
主な方法:
- 米国の409の病院の成人のコホート研究 (2009年−2014年).
- 感染症と臓器機能不全の臨床指標を用いて検出された毒症は,毒症-3の基準から調整された.
- EHRデータは,重度のセプシス/セプティックショックに関する請求データ (ICD-9-CMコード) と比較した.
主要な成果:
- 2014年,セプシスの発生率は臨床基準に基づいて6. 0% (173, 690例) であった.
- 2009年から2014年にかけて,臨床基準を用いたセプシスの発生率は安定していた (年間0. 6%の変化).
- 臨床基準を用いた入院死亡率は減少した (- 3. 3%/年),死亡とホスピス退院の組み合わせは有意に変化しなかった (- 1. 3%/年).
- クレームのデータは増加した発生率 (+10.3%/年) と減少した死亡率 (-7.0%/年) を示した.
- 臨床基準は,比較可能なポジティブな予測値を持つ主張 (69. 7% vs 32. 3%) よりも敏感でした.
結論:
- EHRに基づく臨床データは,安定したセプシス発生率と,2009年から2014年の間に死亡率やホスピス退院率の有意な変化を示しています.
- 断言に基づいた分析では,症の発生率を過大評価し,コード化慣行による死亡率を過小評価することがあります.
- EHRの臨床データは,クレームデータと比較して,セプシスの監視についてより客観的な見積もりを提供しています.

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 issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
6.0K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
