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...

Self-Evaluation: Self-Enhancement and Self-Verification

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Pilot and Numeric Relaying

Pilot and Numeric Relaying

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Fischer Projections

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Newman Projections

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Immune Surveillance by NK Cells and Phagocytes

Immune Surveillance by NK Cells and Phagocytes

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.
Natural Killer Cells: The Fast Responders
NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Area of Science:

Public Health Surveillance
Infectious Disease Epidemiology
Antimicrobial Resistance Monitoring

Background:

Invasive pneumococcal disease (IPD) presents a significant public health challenge in Canada, with difficulties in interpreting current trends in serotype distribution and antimicrobial resistance.
The enhanced Invasive Pneumococcal Disease Surveillance System (eIPDSS) pilot project aimed to improve national-level understanding of IPD trends by integrating epidemiologic and laboratory (epi-lab) data.

Purpose of the Study:

To evaluate the eIPDSS pilot project based on five key attributes: usefulness, data quality, simplicity, acceptability, and timeliness.
To develop recommendations for the future implementation of a national IPD surveillance system.

Main Methods:

A mixed-methods evaluation was conducted, utilizing a qualitative survey distributed to eight eIPDSS users and a quantitative analysis of the eIPDSS database.
Recommendations were formulated based on the findings from both the user survey and the database analysis.

Main Results:

The survey achieved a 100% response rate, with the majority of users finding the eIPDSS useful (75%), simple (100%), and acceptable (86%).
Quantitative analysis indicated that most IPD cases (61%) were assessed as timely, but data quality and management issues were identified by both users and the analysis.
Recommended improvements include public health consultation, regular audits, and platform upgrades to address identified data quality and management concerns.

Conclusions:

The eIPDSS, through its linked epi-lab data, successfully enables the detection and analysis of IPD serotype distribution and antimicrobial resistance trends.
The web-based system is characterized by its simplicity, acceptability, and timeliness in data collection.
It is feasible to establish a national surveillance system that links epi-lab data, provided that data quality and management issues are addressed through planned improvements.
