Barriers to and Facilitators of Iron Therapy in Children with Iron Deficiency Anemia

Abstract

To characterize barriers to and facilitators of successful iron therapy in young children with iron deficiency anemia (IDA) from an in-depth parental perspective. Prospective, mixed methods study of children age 9months to 4years with a diagnosis of nutritional IDA by clinical history and laboratory criteria and their parents. Clinical data were obtained from the electronic health record. Semistructured interviews focused on knowledge of IDA, clinical effects, experience with iron therapies, and motivation were conducted with the parent who identified as the child's primary caregiver. Twenty patient-parent dyads completed the study; 80% (n=16) identified as Hispanic/Latino (white). Patients' median age was 23months (50% male); median initial hemoglobin concentration was 8.2g/dL and duration of oral iron therapy was 3months. Parents' median age was 29years (85% female); 8 interviews (40%) were conducted in Spanish. Barriers included difficulty in administering oral iron owing to side effects and poor taste. Facilitators included provision of specific instructions; support from healthcare providers and additional caregivers at home; motivation to benefit child's health, which was strengthened by strong emotional reactions (ie, stress, anxiety) to therapy and follow-up; and an appreciation of child's improvement with successful completion of therapy. Our findings support the need for interventions designed to promote oral iron adherence in children with IDA. Rather than focusing on knowledge content related to IDA, interventions should aim to increase parental motivation by emphasizing the health benefits of adhering to iron therapy and avoiding more invasive interventions.
