Assessment of the Cardiovascular System I: Subjective Data

641
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

366
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...

COPD: Pathogenesis and Clinical Features

1.6K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Factors Affecting Illness01:18

Factors Affecting Illness

4.8K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

394
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:

  • Emergency Medicine
  • Infectious Diseases
  • Data Science

Background:

  • The COVID-19 pandemic significantly impacted emergency departments (EDs) with diverse patient presentations.
  • Understanding chief complaints is crucial for managing patients with suspected or confirmed COVID-19.

Purpose of the Study:

  • To evaluate the chief complaints of patients presenting to the ED with suspected or confirmed COVID-19.
  • To analyze the clinical presentation of the pandemic in an emergency setting.

Main Methods:

  • Retrospective computational analysis of ED visits for COVID-19.
  • Utilized descriptive statistics, hierarchical clustering, and hypothesis testing on chief complaints.
  • Included confirmed and suspected COVID-19 cases in adult patients (aged 22+).

Main Results:

  • Analyzed 5015 ED visits (1483 confirmed COVID-19 positive).
  • Identified 209 unique chief complaints; fever and shortness of breath were most prevalent.
  • Discovered seven distinct clusters of symptoms in confirmed COVID-19 cases; older adults (>65) more likely presented with weakness and altered mental status.

Conclusions:

  • Highlights key aspects of evaluating and managing COVID-19 patients in the ED.
  • Identified common chief complaints, age-related differences, and symptom clusters.
  • Provides data for public health officials and providers to identify COVID-19 cases.
