Abstract

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.
