Insights

Paediatric antibiotic prescribing has increased, particularly in young children (0-2 years), signaling a need for new antimicrobial stewardship targets. This study highlights rising trends and specific drug classes requiring attention.

Area of Science:

  • Public Health
  • Pediatric Pharmacology
  • Antimicrobial Stewardship

Background:

  • Antibiotic prescribing is common in pediatric care, often for self-limiting viral infections like upper respiratory tract infections.
  • Previous studies in British Columbia indicated decreasing or static antibiotic prescribing rates.
  • There is a need to identify new targets for provincial antimicrobial stewardship programs.

Purpose of the Study:

  • To identify potential new targets for provincial antimicrobial stewardship efforts in pediatric care.
  • To analyze trends in antibiotic utilization among children in a provincial healthcare system.

Main Methods:

  • Extracted pediatric antibiotic prescription data from a provincial database.
  • Linked prescription data with physician billing and demographic data for diagnostic and patient information.
  • Calculated prescription rates and examined trends by Anatomical Therapeutic Chemical (ATC) classification.

Main Results:

  • The study included an average of 271,134 children annually, with 1,767,652 antibiotic prescriptions.
  • Overall antibiotic utilization increased by 4.5% (453 to 474 prescriptions per 1000 population).
  • The greatest prescribing increases were observed in children aged 0-2 years across all categories, despite a decrease in upper respiratory tract infection prescriptions.

Conclusions:

  • Contrary to past findings, pediatric antibiotic prescribing rates have been increasing since 2013.
  • While broad-spectrum penicillin use has decreased, significant increases in tetracyclines, quinolones, and other antibacterials indicate new targets for stewardship.
  • These findings highlight a potential problem in pediatric antibiotic prescribing and necessitate updated stewardship strategies.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Factors Affecting Drug Response: Overview01:21

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
