Objective: We aimed to investigate the current diagnostic incidence, and medical and psychiatric comorbidities of reactive attachment disorder (RAD) using the National Health Insurance Review and Assessment (HIRA) claims data.
Methods: To examine the diagnostic incidence, we selected patients who were under 10-year-old and who had at least one medical claim containing a 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for RAD (F94.1 and F94.2) and who had not been diagnosed in the previous 360 days, from 2010 to 2012. In this study, we used the term ¡®reactive attachment disorder¡¯ representing for both RAD per se and Disinhibited social engagement disorder. Comorbid disorders were categorized according to ICD-10.
Results: Among 14,029,571, the total population under 10-year-old during 2010-2012, incident cases of RAD were 736. The mean diagnostic incidence of RAD was 5.25 per 100,000 annually. Language disorders (F80-84) were the most common psychiatric comorbidities in both boys and girls in age groups 0-3 years and 4-6 years, and attention deficit hyperactivity disorder was the most common in both sex aged 7-9 years. In non-psychiatric comorbidities, diseases of the respiratory system (J00-99) were the commonest in both sex in all age groups, and diseases of the digestive system (K00-99) were the next.
Conclusion: RAD was very rare in practice and would be disguised as other psychiatric disorders. Children with RAD might have more medical comorbidities than typically developed children.
