Role of Communication in the Nursing Process III: Evaluation and Documentation01:08

Role of Communication in the Nursing Process III: Evaluation and Documentation

2.1K
A successful patient outcome depends mainly on the evaluation stage of the nursing process. Evaluation determines effectiveness by reviewing what was done previously after the completion of nursing interventions. Every time a healthcare professional steps in or administers treatment, they must reassess or evaluate the action to ensure the intended result. During the evaluation phase, there are three probable patient outcomes:

Free-falling Bodies: Example01:05

Free-falling Bodies: Example

32.6K
An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Language01:16

Language

919
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation01:20

Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation

2.6K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

Free-falling Bodies: Introduction

13.0K
All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is...

Area of Science:

  • Clinical Informatics
  • Natural Language Processing
  • Healthcare Quality Improvement

Background:

  • Current healthcare quality reporting often relies solely on coded administrative data.
  • This reliance may lead to incomplete or inaccurate depictions of provider performance.
  • Falls risk screening is a critical component of patient safety and quality care.

Purpose of the Study:

  • To develop and evaluate a natural language processing (NLP) approach for identifying falls risk screenings documented in clinical notes.
  • To assess the accuracy and effectiveness of NLP in capturing data missed by coded administrative systems.
  • To determine if NLP can enhance the completeness and accuracy of healthcare quality reporting.

Main Methods:

  • A natural language processing (NLP) algorithm was developed and tested.
  • The algorithm processed 1,558 clinical notes from 144 eligible patients.
  • A specific lexicon of keywords related to falls risk screening, including negations, was generated.
  • The NLP approach identified patients with falls risk screenings documented only in clinical notes.

Main Results:

  • The NLP algorithm identified 62 patients with falls risk screenings not captured by coded data.
  • Manual review confirmed 59 true positives and 77 true negatives.
  • The NLP approach achieved high performance metrics: 0.92 precision, 0.95 recall, and 0.93 F-measure.
  • This demonstrates the capability of NLP to extract valuable clinical information.

Conclusions:

  • Natural language processing (NLP) can significantly enhance healthcare quality reporting by capturing data from clinical notes.
  • Utilizing NLP can provide a more complete and accurate assessment of provider performance, particularly for screenings like falls risk.
  • This approach offers a valuable tool for improving patient safety and care quality.
