概括
数字健康干预 (DHI) 的算法变化可能会影响患者的护理. 时间回归不连续性 (RDT) 设计有效评估了1型糖尿病管理的算法变化,但对时间范围 (TIR) 没有显著影响.
科学领域:
- 医疗信息学 医疗信息学
- 临床数据分析 临床数据分析
- 糖尿病 技术 技术
背景情况:
- 数字健康干预 (DHIs) 越来越多地用于诊所,使用算法指导患者护理.
- 经常缺乏对DHIs算法变化的严格评估,尽管它可能对患者的治疗结果产生影响.
- 时间回归不连续性 (RDT) 设计为这种变化的因果推理提供了一种方法,但在医学研究中未得到充分利用.
研究的目的:

Issues And Trends In Healthcare Delivery System
5.8K
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.

Regression Toward the Mean
6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Current Trends in Nursing II
1.4K
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,...

Introduction To Survival Analysis
400
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...

Study Designs in Epidemiology
422
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...
