A depressed patient in outpatient settings

Depression is a clinically significant and growing public health issue. As a major global disease burden, its prevalence has been steadily increasing over the years, affecting different demographic groups. Depressive disorder is characterized by a low mood, loss of strength, sadness, insomnia, and inability to feel pleasure. In outpatient settings, up to one-third of patients with depressive symptoms may have a comorbidity. Many different diseases have been associated with depressive symptoms. Cardiovascular, metabolic, inflammatory, oncological, and neurological disorders are associated with an increased risk of depression, potentially due to chronic inflammation, neurochemical dysregulation, and emotional and social issues. As different drugs can cause depressive symptoms, the patient's medical history should include an assessment of the use of such drugs. Primary care physicians play an important role in identifying and treating depression. It is recommended to perform depression screening in all adult female patients in primary care facilities. There are general recommendations for the initial treatment of mild to moderate depressive disorder in adults. In mild depression, initial preference should be given to psychotherapy and symptom monitoring, and if improvement is insufficient, pharmacotherapy is to be used. Psychotherapy, pharmacotherapy or a combination of both should be considered for patients with moderate depression. Psychiatric consultation is recommended for patients with severe depression and urgently for any patient with psychotic symptoms or suicidal thoughts and behaviour. Antidepressants are the basic therapy for depression. Selective serotonin reuptake inhibitors are considered the first-line drugs to treat depression.
