Nursing Clinical Information System01:27

Nursing Clinical Information System

1.2K
Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Clinical Trials01:16

Clinical Trials

10.2K
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...

Clinical Trials: Overview

4.6K
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...

Changes in Skin Color: Clinical Perspectives

3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

COPD: Pathogenesis and Clinical Features01:20

COPD: Pathogenesis and Clinical Features

1.8K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

518
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Area of Science:

  • Clinical Informatics
  • Natural Language Processing
  • Health Data Standards

Background:

  • Semantic interoperability is crucial for clinical information systems managing diverse data.
  • Data provenance is increasingly important, especially for automatically extracted clinical data via text mining.
  • Existing clinical information models may lack robust support for detailed data provenance from text mining.

Purpose of the Study:

  • To demonstrate the harmonization of a commercial clinical text-mining tool's output with the Fast Healthcare Interoperability Resources (FHIR) standard.
  • To identify and integrate crucial data provenance elements, including character ranges and machine-generated confidence values, into FHIR.
  • To enable the embedding of metadata describing the generation process of FHIR instances from clinical narratives.

Main Methods:

  • Analysis of output from a commercial clinical text-mining tool.
  • Identification of essential data provenance features: character ranges and confidence scores.
  • Specification and proposal of necessary extensions to the FHIR standard.
  • Demonstration of embedding provenance metadata within FHIR instances.

Main Results:

  • Successful harmonization of text-mining annotations with the FHIR standard.
  • Character ranges and confidence values identified as key for enriching text-mining results with provenance.
  • Demonstrated feasibility of embedding critical provenance metadata into FHIR resources.

Conclusions:

  • The proposed approach effectively integrates clinical text-mining outputs with FHIR, enhancing data provenance.
  • Embedding provenance metadata improves the reliability and interpretability of automatically extracted clinical data.
  • The specified FHIR extensions facilitate more robust semantic interoperability in clinical information systems.
