Abstract
BackgroundThe overall aim of this study is to present descriptive data regarding the treated prevalence of nine common psychiatric and substance use disorders in the first Primary Care Registry (PCR) in Sweden: Major Depression (MD), Anxiety Disorders (AD), Obsessive-Compulsive Disorder (OCD), Adjustment Disorder (AdjD), Eating Disorders (ED), Personality Disorder (PD), Attention Deficit Hyperactivity Disorder (ADHD), Alcohol Use Disorder (AUD) and Drug Abuse (DA).MethodWe selected 5,397,675 individuals aged ≥18. We examined patterns of comorbidity among these disorders and explored the association between diagnoses in the PCR and diagnoses obtained from Hospital and Specialist care. We explored the proportion of patients with these nine disorders that are only treated in primary health care.ResultsFor four of our disorders, 80% or more of the cases were present only in the PCR: AdjD, DA, AD and MD. For two disorders (OCD and ED), 65–70% of cases were only found in the PCR. For three disorders (PD, AUD, and ADHD), 45–55% of the patients were only present in the PCR.ConclusionThe PCR will, in the future, likely prove to be an important tool for studies in psychiatric epidemiology.
Highlights
The overall aim of this study is to present descriptive data regarding the treated prevalence of nine common psychiatric and substance use disorders in the first Primary Care Registry (PCR) in Sweden: Major Depression (MD), Anxiety Disorders (AD), Obsessive-Compulsive Disorder (OCD), Adjustment Disorder (AdjD), Eating Disorders (ED), Personality Disorder (PD), Attention Deficit Hyperactivity Disorder (ADHD), Alcohol Use Disorder (AUD) and Drug Abuse (DA)
In the 2010 Global Burden of Disease Study, depression and anxiety were ranked second and seventh in their worldwide impact on disease-related disability [2]. Most of these patients are likely seen by a general practitioner (GP), a previous Swedish study [3] suggested that only 25% of the cases of depression and anxiety are identified in primary health care in the country
The probability of divorce was increased for all diagnostic categories, and was strongest for AUD, DA and PD and weakest for OCD. This is the first paper to report that of all cases of AdjD, DA, AD and MD found in the primary health care register, 80% were not found in the outpatient/inpatient registers, indicating that a large majority of the psychiatric consultations occur in primary health care

There are limited nationwide studies in western countries on incidence and prevalence of common psychiatric disorders in primary health care. It is probable that a large proportion of such disorders are treated only
