Errors and Nonadherence in Pediatric Oral Chemotherapy Use.

Area of Science:

• Pediatric Oncology
• Pharmacology
• Patient Adherence

Background:

• Nonadherence and medication errors significantly reduce oral chemotherapy effectiveness.
• The interplay between nonadherence and medication errors in pediatric cancer is understudied.
• Distinct intervention strategies exist for nonadherence and medication errors.

Purpose of the Study:

• To characterize nonadherence and medication errors in children undergoing cancer treatment.
• To provide data for developing targeted intervention strategies.
• To understand the co-occurrence of nonadherence and medication errors in pediatric oncology.

Main Methods:

• Nonadherence assessed via two self-report instruments.
• Medication errors evaluated through medication review and direct observation of home administration.
• Clinical judgment used to determine if errors constituted nonadherence.

Main Results:

• Out of 92 home visits, 72 medication errors were identified.
• Twenty-seven of these errors were also classified as nonadherence instances.
• A specific example involved incorrect dosing of mercaptopurine.
• Clinicians identified family and health system interventions as key for prevention.

Conclusions:

• The co-occurrence of medication errors and nonadherence in pediatric cancer patients is evident.
• Interventions need to concurrently address both medication errors and nonadherence.
• Integrated strategies are crucial for effective self-management support in pediatric cancer care.
