Ten Years (2011-2021) of the Italian Lombardy ADHD Register for the Diagnosis and Treatment of Children and Adolescents with ADHD

Background: The purpose of this article is to update the diagnostic assessment, therapeutic approach, and 12-18 month follow-up of patients added to the Italian Lombardy Attention Deficit Hyperactivity Disorder (ADHD) Register.

Methods: Medical records of patients added to the Registry from 2011 to 2021 were analysed.

Results: 4091 of 5934 patients met the criteria for a diagnosis of ADHD, and 20.3% of them presented a familiarity with the disorder. A total of 2879 children (70.4%) had at least one comorbidity disorder, in prevalence a learning disorder (39%). Nearly all (95.9%) received at least one psychological prescription, 17.9% of them almost one pharmacological treatment, and 15.6% a combination of both. Values of ≥5 of the Clinical Global Impression-Severity scale (CGI-S) are more commonly presented by patients with a pharmacological prescription than with a psychological treatment (p < 0.0001). A significant improvement was reported in half of the patients followed after 1 year, with Clinical Global Impression-Improvement scale (CGI-I) ≤ 3. In all, 233 of 4091 are 18-year-old patients.

Conclusions: A ten-year systematic monitoring of models of care was a fruitful shared and collaborative initiative in order to promote significant improvement in clinical practice, providing effective and continuous quality of care. The unique experience reported here should spread.
