Preventing Medication Errors in Adolescents Transitioning to Adult Care

Abstract

Transitional care represents a critical period for adolescents with chronic diseases as they shift from pediatric to adult healthcare systems. This transition is fraught with the risk of medication errors ranging from dosing inaccuracies to omissions and duplications that can compromise patient safety and clinical outcomes. This review synthesizes current evidence on the epidemiology, mechanisms, risk factors, and clinical implications of medication errors during this transitional period. Special emphasis is placed on practical strategies, emerging technologies, and guideline-driven recommendations for healthcare professionals aiming to mitigate these preventable incidents and optimize continuity of care for adolescent patients.

Introduction

The transition from pediatric to adult care is a complex process involving changes in healthcare providers, systems, and often, medication regimens. Adolescents with chronic conditions are particularly vulnerable to medication errors during this period, owing to developmental, psychosocial, and systemic challenges. Such errors can result in adverse drug events, increased morbidity, and hospitalizations, underscoring the necessity for targeted interventions and multidisciplinary collaboration. This article provides a comprehensive review of the current landscape of medication error prevention in adolescents transitioning to adult care, integrating recent evidence, clinical guidelines, and expert perspectives.

Epidemiology / Disease Burden

Medication errors are a significant source of preventable harm in healthcare, with adolescents transitioning to adult care facing a disproportionately high risk. Studies report error rates ranging from 13% to 30% in this population, particularly among those with complex medication regimens for conditions such as cystic fibrosis, diabetes, epilepsy, and congenital heart disease. The burden is amplified by factors such as polypharmacy, fragmented care, and poor communication between pediatric and adult services. Medication errors during transition can lead to increased emergency visits, hospitalizations, and long-term complications, emphasizing their public health significance and the need for robust prevention strategies.

Pathophysiology

The pathophysiology underpinning medication errors in transitioning adolescents is multifactorial. Cognitive and psychosocial maturation during adolescence affects health literacy, decision-making, and adherence. Simultaneously, changes in pharmacokinetics and pharmacodynamics during puberty can alter drug metabolism and response. System-level factors, including discrepancies in electronic health records, lack of standardized transition protocols, and insufficient handover processes, further compound the risk. Understanding these mechanisms is essential for the development of effective prevention strategies targeting both individual and system-level contributors.

Risk Factors

Numerous risk factors predispose adolescents to medication errors during transition. Key factors include polypharmacy, frequent medication changes, limited self-management skills, and cognitive or psychological comorbidities. Social determinants, such as family dynamics, socioeconomic status, and health literacy, also play critical roles. The absence of structured transition programs and inadequate communication between pediatric and adult providers are major modifiable risk factors. Recognizing these vulnerabilities allows for risk stratification and tailored interventions to mitigate error occurrence.

Clinical Features

Medication errors may manifest as acute or insidious clinical events. Common presentations include subtherapeutic response, adverse drug reactions, and exacerbation of underlying disease. For example, insulin omission in diabetic adolescents may result in hyperglycemia or diabetic ketoacidosis, while antiepileptic medication errors can provoke breakthrough seizures. Subtle signs, such as unexplained clinical deterioration or poor disease control, should prompt careful review of the medication reconciliation process during transitional care. Early recognition and prompt management are essential to prevent escalation of harm.

Diagnosis

Diagnosing medication errors in the transitional adolescent population requires a high index of suspicion and a systematic approach. Comprehensive medication reconciliation including review of current prescriptions, over-the-counter drugs, and supplements is critical. Collaboration with pharmacists, caregivers, and both pediatric and adult providers aids in detecting discrepancies. Tools such as the Medication Appropriateness Index and trigger tools for adverse drug events can facilitate identification. Documentation and root cause analysis of identified errors are essential for ongoing quality improvement.

Treatment & Management

Management of medication errors involves immediate correction of the error and mitigation of any resultant harm. Interventions include adjustment or discontinuation of the offending medication, supportive care, and monitoring for sequelae. Long-term management focuses on patient and family education, empowerment of adolescents in self-care, and implementation of structured transition protocols. Multidisciplinary transition clinics and care coordination teams have demonstrated efficacy in reducing errors and improving outcomes. Ongoing reassessment and feedback loops are vital components of an effective management strategy.

Recent Advances / Emerging Therapies

Recent advances in health information technology have shown promise in reducing medication errors during transition. Electronic health record (EHR) interoperability facilitates seamless handover and accurate medication reconciliation. Clinical decision support systems (CDSS) can provide alerts for potential drug interactions, duplications, and dosing errors. Mobile health (mHealth) applications, tailored to adolescent users, support medication adherence and self-management. Emerging models, such as transition navigators and peer support programs, offer additional layers of safety and support. Ongoing research into pharmacogenomics and individualized medicine may further refine error prevention strategies in the future.

Guideline Recommendations

Professional societies such as the American Academy of Pediatrics (AAP) and the Society for Adolescent Health and Medicine (SAHM) advocate for structured transition programs incorporating medication reconciliation, patient education, and clear communication between providers. Key recommendations include early initiation of transition planning, individualized care plans, and the use of standardized checklists. Involving adolescents in shared decision-making and promoting health literacy are emphasized. Regular training for healthcare professionals in transition care and medication safety is also recommended to sustain high standards of practice.

Conclusion

The transition from pediatric to adult care is a high-risk period for medication errors among adolescents with chronic conditions. A thorough understanding of the epidemiology, mechanisms, and risk factors is essential for clinicians to implement targeted prevention strategies. Advances in health information technology, structured transition protocols, and collaborative care models offer promising avenues for error reduction. Adherence to evidence-based guidelines and ongoing education of both patients and providers are critical to ensuring safe and effective transitional care, ultimately improving long-term outcomes for adolescent patients.
