Fixed Action Patterns01:06

Fixed Action Patterns

16.5K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

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.

Sequence Networks of Rotating Machines01:24

Sequence Networks of Rotating Machines

142
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Methods of Documentation VII: EMR

913
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

Time-Series Graph00:54

Time-Series Graph

4.5K
A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

Area of Science:

  • Health Informatics
  • Clinical Workflow Analysis
  • Data Mining in Healthcare

Background:

  • Electronic Health Records (EHR) generate vast amounts of audit log data.
  • Understanding clinician workflows within EHR systems is crucial for optimizing healthcare delivery and system design.
  • Current methods for analyzing EHR audit logs are often manual and time-consuming.

Purpose of the Study:

  • To develop and apply novel computational techniques for analyzing clinician workflows in EHR systems.
  • To characterize distinct patterns of clinician activities within EHR audit log data.
  • To explore the potential of unsupervised machine learning for identifying workflow patterns.

Main Methods:

  • Utilized a novel combination of context-based embedding and graph-based dimensionality reduction.
  • Applied these techniques to analyze sequences of EHR-based audit log data.
  • Employed unsupervised learning approaches to identify workflow patterns without pre-defined labels.

Main Results:

  • Successfully identified distinct groups of clinical tasks based on EHR audit log sequences.
  • Demonstrated the effectiveness of the combined embedding and dimensionality reduction techniques.
  • Revealed underlying structures in clinician EHR usage patterns.

Conclusions:

  • The developed methods offer a powerful, semi-automated approach to characterizing EHR clinician workflows.
  • These findings suggest significant potential for unsupervised methods in understanding and optimizing healthcare IT usage.
  • Further research can build upon these techniques to enhance EHR system design and clinical efficiency.
