概括
电子健康记录数据显示出血发病率和死亡率稳定,与索赔数据趋势形成鲜明对比. 这突显了临床数据对于精确的败血症监测和了解患者结果的重要性.
科学领域:
- 危急护理医学
- 医疗信息学
- 流行病学
背景情况:
- 基于索赔的分析表明败血症发病率上升,死亡率下降.
- 然而,声明数据可能缺乏临床准确性,并受到编码变化的影响.
研究的目的:
- 使用详细的电子健康记录 (EHR) 临床数据估计美国全国性败血症发病率和趋势.
- 将基于EHR的估计与基于传统索赔的估计进行比较.
主要方法:
- 美国409家医院成年患者的回顾性队列研究 (2009-2014).
- 使用感染和器官功能障碍的临床指标确定败血症,根据败血症-3标准进行调整.
- 与严重败血症/败血性休克的索赔数据 (ICD-9-CM代码) 进行比较.
主要成果:
- 在2014年,根据临床标准,败血症发病率为6.0% (173,690例).
- 从2009年至2014年,使用临床标准的败血症发病率保持稳定 (每年变化0.6%).
- 使用临床标准的住院死亡率下降 (- 3. 3%/年),但结合死亡/住院出院没有显著变化 (-1. 3%/年).
- 索赔数据显示发生率上升 (+10.3%/年) 和死亡率下降 (-7.0%/年).
- 临床标准比具有相似的积极预测价值的说法更敏感 (69.7%对32. 3%).
结论:
- 基于电子健康记录的临床数据显示,自2009年至2014年间的败血症发病率稳定,死亡率和住院出院率没有显著变化.
- 基于索赔的分析可能会高估败血症发病率,低估由于编码做法导致的死亡率.
- 与索赔数据相比,EHR临床数据为败血症监测提供了更客观的估计.

Healthcare Associated Infections II: Preventive Measures
4.4K
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.

Current Trends in Nursing II
3.6K
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...
