Summary
Acute pyelonephritis (APN) incidence is rising in Korea, affecting all demographics. This trend highlights changing epidemiology and the need for updated treatment strategies for this common infection.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Acute pyelonephritis (APN) is a frequent community-acquired bacterial infection.
- Increasing antimicrobial resistance may alter APN's epidemiological patterns.
- Understanding current APN trends in Korea is crucial.
Purpose of the Study:
- To investigate the current epidemiology of acute pyelonephritis (APN) in Korea.
- To analyze population-wide APN incidence and characteristics using national health data.
Main Methods:
- Utilized the Health Insurance Review and Assessment Service claims database (2010-2014).
- Identified APN cases using ICD-10 codes N10 or N12 with multiple claims within 14 days.
- Analyzed incidence rates, patient demographics, hospitalization, recurrence, and costs.
Main Results:
- Annual APN incidence increased from 35.6 to 43.8 per 10,000 persons (2010-2014).
- Rising trends observed across all patient groups (inpatients, outpatients, men, women, age groups).
- Women were disproportionately affected (71.3 vs. 6.5 per 10,000); recurrence rate was 15.8%; inpatient costs were significantly higher.
Conclusions:
- The epidemiology of acute pyelonephritis in Korea is evolving.
- A significant increasing incidence rate of APN is confirmed.
- These findings necessitate a re-evaluation of APN management strategies.

01:28Acute Pyelonephritis II: Diagnostic Studies and Management
408
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

01:27Acute Pyelonephritis I: Introduction
649
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

01:20Study Designs in Epidemiology
978
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

01:27Confounding in Epidemiological Studies
806
Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...

01:29Bias in Epidemiological Studies
1.4K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:26Introduction to Epidemiology
1.8K
Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...
