Data Collection I01:30

Data Collection I

6.2K
Data collection gathers information needed to make accurate judgments about a patient's present condition. During a health history interview, subjective data is collected from the patient, their caregivers, or family members, and objective data is collected through observations and physical assessment. Patients are the primary source of subjective data. Thus information gathered from patients through interviews, observations, and physical examination is primary data. Secondary sources of...

Data Validation01:03

Data Validation

5.0K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Methods of Documentation IV: Focus Charting

1.0K
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:

Methods of Documentation V: CBE

899
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

Area of Science:

  • Health Informatics
  • Data Management

Background:

  • Secondary use of clinical health data requires integrating heterogeneous datasets.
  • Clinical data warehouses facilitate data availability but can lead to data silos.
  • Users often lack a comprehensive overview of all available data within a data warehouse.

Purpose of the Study:

  • To address the challenge of data silos in clinical data warehouses.
  • To evaluate data catalog solutions for improving data accessibility and discoverability.
  • To conduct a market survey and vendor comparison for data catalog system selection.

Main Methods:

  • Explorative online market survey of data catalog vendors.
  • Vendor performance assessment based on seven weighted selection criteria.
  • Comparative analysis of leading data catalog solutions.

Main Results:

  • Three vendors achieved the highest scores in the assessment.
  • Vendor performance results were closely competitive.
  • The study identified potential data catalog solutions for clinical data environments.

Conclusions:

  • Data catalogs are crucial for overcoming data silos in clinical data warehouses.
  • Further detailed investigations and test installations are necessary for optimal system selection.
  • The findings provide a basis for selecting a data catalog to enhance secondary data use.
