概括
人工智能 (AI) 提供了一种新的方法来对手术护理质量进行基准评估. 这种非线性AI方法识别了具有更好或更差结果的特定患者群体,并确定了急诊外科手术中需要改进的领域.
科学领域:
- 外科手术质量基准测试的使用
- 医疗保健中的人工智能
- 医学中的预测分析.
背景情况:
- 目前的外科手术护理质量基准仅限于线性模型.
- 现有的方法无法解释复杂的手术前变量相互作用.
- 需要新的非线性AI方法来准确评估外科护理质量.
研究的目的:
- 利用先进的非线性人工智能 (AI) 来衡量紧急外科护理的质量.
- 确定与外科手术结果相关的特定患者表型和护理途径.
主要方法:

Issues And Trends In Healthcare Delivery System
5.7K
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.

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,...
