Insights

Parental reports of medication adherence in children with inflammatory bowel disease (IBD) can be improved. New methods can correct subjective reports for better adherence assessment and improved treatment outcomes.

Area of Science:

  • Pediatric Gastroenterology
  • Pharmacology
  • Health Services Research

Background:

  • Accurate medication adherence assessment is crucial for managing pediatric inflammatory bowel disease (IBD).
  • Parental subjective reports are commonly used but may overestimate adherence.
  • Electronic monitoring (EM) provides objective adherence data.

Purpose of the Study:

  • To evaluate the accuracy of parent-reported medication adherence in children with IBD.
  • To present and validate methods for correcting parent-reported adherence data.
  • To improve the reliability of adherence assessment in pediatric chronic illness management.

Main Methods:

  • 40 children with IBD underwent electronic monitoring (EM) for medication adherence.
  • Parents provided subjective adherence reports.
  • Receiver operating characteristic (ROC) analyses identified optimal cut-points for detecting non-adherence.
  • Two methods were applied to derive correction factors for parent reports.

Main Results:

  • Parental reports significantly correlated with EM adherence but were consistently higher.
  • A 90% adherence cut-point demonstrated the highest sensitivity and specificity.
  • Both derived correction factors effectively adjusted parent-reported adherence towards EM levels.

Conclusions:

  • Empirically derived correction factors can significantly enhance the accuracy of parent-reported medication adherence.
  • Improved adherence assessment has implications for self-management interventions.
  • Accurate adherence data can inform clinical prescribing and enhance medication safety in pediatric IBD.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

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...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

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...

Dosage Regimens: Partial Pharmacokinetic Parameters

It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...

Dosage Regimen: Individualization

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...
