Documentation of Nursing Diagnosis

Documentation of Nursing Diagnosis

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 assessment...

Automated Microbial Diagnostics

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

Statistical Software for Data Analysis and Clinical Trials

Statistical Software for Data Analysis and Clinical Trials

Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Methods of Documentation IV: Focus Charting

Methods of Documentation IV: Focus Charting

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:

Diagnostic and Statistical Manual of Mental Disorders (DSM)

Diagnostic and Statistical Manual of Mental Disorders (DSM)

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...

Classification of Illness

Classification of Illness

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 and...

Area of Science:

Oncology
Biostatistics
Health Informatics

Background:

Cancer registries often receive conflicting diagnosis dates from various sources.
Manual consolidation of these dates is time-consuming and labor-intensive.
No prior algorithms existed for automating diagnosis date consolidation.

Purpose of the Study:

To develop and evaluate an algorithm for consolidating multiple cancer diagnosis dates.
To improve the efficiency and accuracy of cancer registry data management.

Main Methods:

A "take the best" heuristic algorithm was developed.
The algorithm incorporated diagnosis dates, case class, service type, and first contact date.
Algorithm performance was validated against manual reviews by certified tumor registrars (CTRs).

Main Results:

The algorithm successfully consolidated single diagnosis dates for 94.7% of 209,907 tumors.
High agreement was observed between the algorithm and manual review: 97.6% for year, 89.9% for month/year, and 81.4% for month/year/day.
The algorithm significantly outperformed original manual consolidation methods.

Conclusions:

The developed algorithm is accurate, efficient, and reliable for consolidating cancer diagnosis dates.
This tool can assist cancer registries in establishing standardized data consolidation practices.
Implementation of this algorithm can enhance the quality of cancer surveillance data.
