- 创伤外科 手术 创伤外科
- 医疗信息学 医疗信息学
背景情况:
- 伤害是美国的主要死亡原因,需要有效的创伤系统.
- 创伤中心 (TC) 按级别指定,指导资源获取,但不是特定的外科护理.
- 了解超越TC指定的护理模式对于系统优化至关重要.
研究的目的:
- 确定伤害护理的不同模式,区分创伤中心 (TC) 和非创伤中心 (非TC).
- 探索手术护理的数量和类型以及患者和医院的特点如何定义医院集群.
- 评估已识别的护理模式与现有的TC级别指定之间的一致性.
主要方法:
- 利用华盛顿州2016年的住院患者出院数据,包括所有TC和非TC.
- 在医院特征上进行无监督的集群 (围绕中的分区),包括手术护理 (体积,分布) 和其他特征.
- 进行了三组分析:第一组 (外科护理+其他特征),第二组 (骨科手术+其他特征),第三组 (仅外科护理).

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Specialized Care Centers and Settings-I
936
Specialized care settings or centers are situated in convenient locations within the community and offer care to a specific group or population. They consist of daycare facilities, mental health facilities, rural health facilities, educational institutions, industries, shelters for the homeless, and rehabilitation facilities.
Daycare centers
They provide several functions. Some facilities care for healthy newborns and children whose parents work, while others are medically focused and care for...

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Comparing the Survival Analysis of Two or More Groups
162
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Cancer Survival Analysis
334
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
