Methods of Documentation IV: Focus Charting

1.1K
Focus Charting, also known as the focus charting system or "focus documentation," is a systematic documentation approach used in healthcare to organize patient information in medical records.
It typically involves three columns for recording information:

How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

34.9K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Introduction to Documentation and Reporting

2.1K
Documentation is the systematic process of formally recording, maintaining, and communicating information.
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...

Methods of Documentation I: Source-Oriented Records

1.2K
Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

Flow Cytometry01:23

Flow Cytometry

13.4K
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Data Collection by Observations01:08

Data Collection by Observations

12.4K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

    Area of Science:

    • Information Science
    • Health Informatics
    • Human-Computer Interaction

    Background:

    • Systematic reviews (SR) are crucial for clinical decisions, but literature volume hinders efficient information discovery.
    • Existing human-in-the-loop information retrieval (HIR) methods struggle to meet clinician needs as keyword queries don't always match information requirements.
    • Current document categorization methods are limited as they require pre-defined criteria and consider entire documents, not specific answers.

    Purpose of the Study:

    • To develop DocFlow, a visual analytics system designed to enhance information-seeking for clinicians.
    • To enable document retrieval based on natural language questions, moving beyond keyword-based searches.
    • To facilitate intelligent document categorization by locating answers within documents, adaptable to user-defined criteria.

    Main Methods:

    • Developed DocFlow, a visual analytics system incorporating natural language question processing.
    • Implemented a flexible user interface allowing sequential question arrangement for customized retrieval and categorization.
    • Validated the system through case studies and feedback from domain experts.

    Main Results:

    • DocFlow effectively retrieves documents that answer specific user questions posed in natural language.
    • The system intelligently categorizes documents based on identified answers, accommodating undefined and dynamic criteria.
    • User feedback and case studies confirmed the system's utility and effectiveness in supporting information-seeking.

    Conclusions:

    • DocFlow significantly improves the efficiency and relevance of information retrieval for clinicians.
    • The system's ability to process natural language questions and dynamically categorize documents addresses key challenges in medical literature review.
    • DocFlow offers a flexible and effective solution for navigating the growing volume of research evidence to support clinical practice.
