Classification of Illness01:17

Classification of Illness

8.1K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Documentation of Nursing Diagnosis

1.4K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

290
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

31
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Issues And Trends In Healthcare Delivery System

5.9K
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.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

  • Digital Health
  • Natural Language Processing
  • Health Informatics

Background:

  • Evaluating the actionability of mental healthcare information is crucial for patient engagement.
  • Existing readability tools may not fully capture the nuances of actionable health content.
  • A quantitative instrument is needed for automated assessment of mental health information quality.

Purpose of the Study:

  • To develop and validate a quantitative instrument for automatic evaluation of mental healthcare information actionability.
  • To compare the performance of an optimized classifier against existing readability tools and baseline classifiers.
  • To enhance the interpretability and diagnostic utility of classifiers for mental health information.

Main Methods:

  • Collected and classified large datasets of generic and patient-specific mental healthcare information from certified websites.
  • Developed an optimized classifier using both semantic and structural features.
  • Compared the optimized classifier's performance (sensitivity and specificity) with popular readability tools and non-optimized classifiers.
  • Utilized statistical analyses to validate performance metrics.

Main Results:

  • The optimized classifier demonstrated statistically higher sensitivity compared to classifiers using only semantic or structural features (p < 0.001).
  • The optimized classifier showed statistically higher specificity than classifiers using only structural or semantic features (p = 0.001).
  • An optimized classifier using 19 semantic-structural variables performed best, indicating high efficiency.

Conclusions:

  • The developed optimized classifier effectively evaluates the actionability of mental healthcare information.
  • Combining linguistic and statistical insights significantly improves classifier interpretability and utility.
  • This tool can guide the development and evaluation of actionable and usable mental healthcare resources.
