Insights

Inappropriate antibiotic prescribing for pediatric respiratory infections significantly decreased in Memphis, Tennessee, from 1992 to 2002. Pediatricians shifted to broader-spectrum antibiotics, highlighting the need for ongoing physician education on appropriate antibiotic use.

Area of Science:

  • Pediatric Infectious Diseases
  • Antimicrobial Stewardship
  • Public Health

Background:

  • Published data shows a national decline in antibiotic use for pediatric respiratory tract infections.
  • This study investigates antibiotic prescribing trends in two pediatric practices in Memphis, Tennessee.
  • The research aims to determine if inappropriate antibiotic use has decreased regionally.

Purpose of the Study:

  • To evaluate changes in inappropriate antibiotic prescribing for pediatric respiratory tract infections.
  • To assess the impact of a decade of antibiotic stewardship initiatives in a specific region.
  • To identify shifts in antibiotic classes used for pediatric respiratory infections.

Main Methods:

  • A retrospective chart review of 1504 pediatric visits for respiratory tract infections between 1992 and 2002.
  • Visits were from 7 offices across 2 pediatric practices, with data collected in alternate years.
  • Generalized estimating equations were used to analyze changes in inappropriate prescribing over time.

Main Results:

  • Antibiotic prescriptions decreased from 85% in 1992 to 67% in 2002.
  • Inappropriate antibiotic prescribing declined significantly (OR 0.28; 95% CI 0.20-0.38).
  • Use of amoxicillin-clavulanic acid and azithromycin increased, while amoxicillin use decreased.

Conclusions:

  • A substantial reduction in inappropriate antibiotic use was observed in Memphis pediatric practices.
  • Pediatricians increasingly prescribed broad-spectrum antibiotics for respiratory tract infections.
  • Continued physician education is crucial for maintaining and improving appropriate antibiotic prescribing practices.

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...

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

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 a challenge in...
