Pediatric multimorbidity has emerged as a significant clinical challenge that extends beyond the traditional single-disease model of pediatric care. The coexistence of multiple chronic conditions in children and adolescents generates complex diagnostic and therapeutic scenarios that demand advanced clinical reasoning, coordinated care, and long-term management strategies. This review synthesizes current international evidence on pediatric multimorbidity, with a specific focus on its implications for diagnostic complexity, therapeutic burden, polypharmacy, and healthcare utilization, framed within an internal medicine perspective. The findings highlight that pediatric multimorbidity follows identifiable patterns of disease clustering, frequently involving neurodevelopmental, mental health, respiratory, metabolic, and neurologic conditions. These patterns are associated with increased diagnostic uncertainty due to overlapping symptoms, atypical presentations, care fragmentation, and medication-related confounding. Therapeutic management is similarly complex, with polypharmacy and cumulative treatment burden representing central risks for patient safety and quality of life. Care coordination and family-centered approaches emerge as critical mechanisms for mitigating complexity, while gaps in transition planning to adult care remain a persistent challenge. From an educational standpoint, pediatric multimorbidity offers a valuable framework for teaching core internal medicine competencies, including diagnostic reasoning under uncertainty, systems-based practice, and patient-centered care. This review underscores the need to integrate multimorbidity-focused approaches into medical training and clinical practice, particularly within healthcare systems in Mexico, Colombia, and Ecuador.

Integrated pediatric care has emerged as a critical approach to improving clinical outcomes by bridging the gap between medical management and surgical decision-making. This review analyzes current evidence (2020–2025) on interdisciplinary pediatric care, focusing on its impact across multiple clinical domains, including neonatal surgery, trauma, minimally invasive procedures, oncology, and critical care. A structured narrative methodology was employed, incorporating 20 high-impact studies from international databases. The findings demonstrate that higher levels of integration—particularly those involving coordinated, real-time collaboration and standardized clinical pathways—are consistently associated with reduced morbidity, lower complication rates, shorter hospital stays, and improved recovery. The analysis also highlights the central role of perioperative care as a connecting element between medical and surgical practices. Variability in implementation was observed across healthcare systems, with high-income countries showing more structured integration, while middle-income regions such as Mexico, Colombia, and Ecuador are progressing toward adaptable models despite systemic challenges. Overall, the evidence supports integrated pediatric care as a comprehensive, patient-centered framework that enhances clinical effectiveness and healthcare efficiency.
