Thyroid function assessment before and after diagnosis of schizophrenia: A community-based study.

Alterations in thyroid hormone levels may affect brain and mental disorders. Conversely, schizophrenia and its antipsychotic treatments can affect thyroid hormone levels. However, data on thyroid hormone levels during the course of schizophrenia disorder are scant. The aim of the study was to assess the rate of thyroid hormone disorders in outpatients before and after diagnosis of schizophrenia. A retrospective matched-control design was used. The cohort included 1252 patients suffering from ICD-10 schizophrenia, and 3756 control subjects matched for gender, age, socioeconomic status, and origin. All were identified from the database of a large health management organization. The pertinent clinical data were collected from the electronic medical records. There was no significant between-group difference in the distribution of thyroid-stimulating hormone levels. Before diagnosis, both groups had a similar rate of hypothyroidism. After diagnosis of schizophrenia and initiation of antipsychotic treatment, the rate of hypothyroidism was significantly higher in the patient group. It remained significantly higher after exclusion of patients receiving lithium. The increased rate of hypothyroidism in patients with schizophrenia after, but not before, the diagnosis of schizophrenia suggests that antipsychotic medications may affect thyroid hormone levels. Screening for thyroid disorders is warranted in patients with schizophrenia under antipsychotic treatment.

A short-term intervention in a multidisciplinary referral clinic for primary care frequent attenders: description of the model, patient characteristics and their use of medical resources.

BACKGROUND: Frequent attenders in primary care are a professional challenge for family physicians, and the medical costs of their care can be very high. Some of them suffer from somatization and are concerned solely with their physical complaints, although somatic complaints are the most common presentation of anxiety and depression. To assess and treat these patients comprehensively, a multidisciplinary clinic was created in the community. METHODS: This study describes the first 40 patients referred to the clinic. All patients completed a mental health screening questionnaire and a functional assessment of health. The utilization of medical resources was assessed by chart review for the year before and the year after the first encounter in the clinic. The intervention consisted of a comprehensive bio-psychosocial consultation where life history and medical symptoms were woven together into a new narrative. The intervention also included pharmacological treatment and short-term psychological interventions. RESULTS: The majority of referred patients were women and their average age was 52 years. Headache was the leading symptom, followed by fatigue. The mean number of reported symptoms for each individual patient was 10. Mental health problems were mainly somatization, depression and anxiety. The average yearly costs per person of US$4035 were reduced to US$1161 the year following referral. CONCLUSIONS: The integrated approach of the clinic satisfied at least three needs: of the patient, of the referring physician and of the health maintenance organization. The results of this uncontrolled pilot study suggest that this intervention helped to modify illness behaviour, decreasing the costs of medical investigations.
