Clinical Trials01:16

Clinical Trials

6.9K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

148
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Hazard Ratio01:12

Hazard Ratio

160
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Clinical Trials: Overview01:11

Clinical Trials: Overview

3.0K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Methods of Documentation V: CBE01:23

Methods of Documentation V: CBE

929
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

Area of Science:

  • Health Informatics
  • Medical Technology Evaluation
  • Systematic Review Methodology

Background:

  • Clinical health technologies encompass a range of digital tools used in healthcare.
  • Evaluating these technologies is crucial for ensuring their efficacy and safety.
  • Systematic reviews provide a robust framework for synthesizing existing research.

Purpose of the Study:

  • To systematically review and classify the evaluation methods employed for clinical health technologies.
  • To identify trends in the types of technologies evaluated and the methodologies used.
  • To highlight the most prevalent evaluation approaches in the field.

Main Methods:

  • A systematic electronic search was conducted across Scopus, PubMed, and ISI databases.
  • Search terms included "evaluation," "technology," and "health," limited to publications from 2011-2021.
  • Initial screening of 8,149 references was followed by full-text review of 2,674 articles, resulting in 174 included studies.

Main Results:

  • The majority of evaluated technologies were PC-based systems (N=107) compared to mobile apps (N=67).
  • Primary technology applications included treatment (43%) and education (26%).
  • Usability testing was the most common evaluation method (66%, N=115), while qualitative methods were least used (1%, N=2).

Conclusions:

  • Usability evaluation is the predominant method for clinical health technologies.
  • PC-based systems are more frequently evaluated than mobile applications.
  • The findings underscore the importance of usability in the development and deployment of health technologies, especially in telemedicine.
