Abstract

ARAGONES, Enric et al. Prevalence in Adults of Attention Deficit Hyperactivity Disorder Using the Medical Records of Primary Care. Rev. Esp. Salud Publica [online]. 2010, vol.84, n.4, pp. 415-420. ISSN 1135-5727.  http://dx.doi.org/10.1590/S1135-57272010000400006.

Background: ADHD in adults is not uncommon and, according to recent epidemiological data, has a population prevalence of 3-4%. However, there is major unawareness of this disorder among doctors, particularly in primary care. The aim of this study is to determine the prevalence of the diagnosis of ADHD recorded in adults and the proportion of patients with drug prescriptions for this disorder in primary care. Methods: This is a cross-sectional study on databases of computerised primary care medical records. The target population is adults (18-44 years) assigned to primary care centres of the Catalan Health Institute (n = 2,452,107). We obtained the proportion of patients with ADHD (F90/ICD-10 code) registered as active problem, and the proportion of patients with a specific prescription for ADHD in adults: methylphenidate, methylphenidate extended release or atomoxetine. Results: The prevalence of recorded ADHD is 0.04% (0.07% in men, 0.02% in women). The percentage of patients with a specific prescription for ADHD is 0.07% (0.08% in men, 0.05% in women). 32.05% of ADHD patients had specific prescription. Conclusion: The diagnosis of ADHD in adults and specific treatment are extremely low in primary care. These results contrast with population data: registered ADHD is 1/85 of the population prevalence.
