Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

972
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: Drug Excretion

395
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...

Pharmaceutical Poisoning: Potential Scenarios

116
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Dosage Regimens: Designs and Approaches

589
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant

356
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...

Dosage Regimen: Fixed Dose01:01

Dosage Regimen: Fixed Dose

2.3K
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

Summary

An enhanced dose range checking (DRC) system improved medication safety in pediatric intensive care units. The system significantly reduced unmodified orders and increased dose reductions or cancellations, enhancing prescription accuracy.

Area of Science:

  • Medical Informatics
  • Pediatric Critical Care
  • Health Informatics

Background:

  • Prescription errors pose a significant risk in pediatric intensive care settings.
  • Existing dose range checking (DRC) systems may have limitations in effectiveness.
  • Optimizing DRC systems is crucial for improving patient safety in critical care.

Purpose of the Study:

  • To develop and evaluate an enhanced dose range checking (DRC) system for pediatric intensive care units (PICU) and pediatric cardiovascular intensive care units (PCVICU).
  • To assess the impact of "soft" and "hard" alerts on prescription error rates and practitioner responses.
  • To improve medication safety by reducing inappropriate medication orders.

Main Methods:

  • Implementation of an enhanced DRC system with "soft" and "hard" alerts in PICU and PCVICU settings.
  • Retrospective review of practitioner responses to DRC alerts.
  • Comparison of alert rates, alert types, and order modifications before and after system implementation.

Main Results:

  • Alert rates increased significantly from 0.3% to 3.4% post-implementation (P < 0.001).
  • Practitioners responded to soft alerts by reducing doses in 24.7% of orders post-implementation, compared to 10% previously.
  • Order cancellation rates increased, and unmodified medication orders triggering soft alerts decreased significantly after implementation.

Conclusions:

  • The enhanced DRC system, incorporating both soft and hard alerts, led to a statistically significant decrease in unmodified medication orders.
  • The system successfully increased the rate of dose reductions and order cancellations, indicating improved prescription accuracy and safety.
  • Alerts became more clinically relevant and actionable after system enhancement, contributing to better medication management in pediatric critical care.
