Incidence and Severity of Community- and Hospital-Acquired Hyponatremia in Pediatrics

Area of Science:

• Pediatrics
• Clinical Chemistry
• Epidemiology

Background:

• Hyponatremia is the most frequent electrolyte imbalance in hospitalized children.
• The precise incidence and severity of hyponatremia in pediatric populations require further elucidation.

Purpose of the Study:

• To ascertain the incidence and severity of both community- and hospital-acquired hyponatremia.
• To identify risk factors associated with hyponatremia in pediatric patients.

Main Methods:

• Analysis of plasma sodium and discharge diagnoses for 5550 children admitted between June 2012 and December 2019.
• Logistic regression modeling was employed to identify significant correlations.
• Hyponatremia was categorized into mild, moderate, and severe based on sodium levels.

Main Results:

• The incidence of community-acquired hyponatremia was 15.8%, while hospital-acquired hyponatremia was 1.4%.
• The majority of cases were mild (90.8%) or moderate (8.6%); severe hyponatremia was rare (two cases).
• Age (2-11 years) and diagnoses including infections, cardiovascular, and gastrointestinal disorders were significantly correlated with hyponatremia.

Conclusions:

• Community-acquired hyponatremia is significantly more prevalent than hospital-acquired hyponatremia in pediatric care.
• Severe hyponatremia is uncommon in both settings, and no clinical complications were observed.
• Children aged 2-11 with infections or certain chronic conditions are at higher risk.
