Principles of Disease Surveillance

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Nursing Clinical Information System

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Applications of GIS: Disaster Management and Emergency Response

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Area of Science:

Health Information Technology
Infectious Disease Management
Clinical Decision Support Systems

Background:

Health information technology, specifically clinical decision support (CDS), has shown promise in reducing patient safety errors within electronic health records (EHRs).
The emergence and re-emergence of infectious diseases pose a significant challenge to healthcare facilities, necessitating rapid response capabilities.
Previous experience with EHR builds for Ebola and Zika decision support alerts informed the design strategy.

Purpose of the Study:

To develop a modular approach for the rapid deployment of infectious disease CDS into clinical workflows.
To evaluate the usability of this newly designed CDS module.
To assess the impact of the CDS module on diagnostic testing efficiency using a tuberculosis (TB) use case.

Main Methods:

A quality improvement project was undertaken to develop, implement, and evaluate a rapid deployment CDS module.
The module's design and build were guided by subject matter expert feedback and lessons learned from prior EHR alert strategies.
Usability was assessed using the Task, User, Representation, and Function (TURF) framework, with high satisfaction reported by providers and nurses.

Main Results:

The implementation of the TB CDS module led to decreased order times for diagnostic studies in pre-alert and post-alert TB cases.
Clinician usability satisfaction remained high among both providers and nurses.
The findings indicate that usable CDS systems contribute to more efficient workflows.

Conclusions:

Satisfied clinicians and usable systems enhance workflow efficiency, leading to safer and more timely diagnostic testing.
The modular approach facilitates the rapid integration of CDS for emerging infectious diseases.
This quality improvement project demonstrates the value of adaptable CDS in managing infectious disease threats.
