Brief Summary
The project investigates long-term prognosis and predictors of treatment outcomes for difficult-to-treat depression in patients in secondary psychiatric care. The current patient cohort was collected in 2012-2021 in the study "Pharmacogenetics in patients with depression with specific focus on difficult-to-treat depression, suicide attempt and CYP2D6". The cohort consists of 415 patients, examined carefully regarding diagnostic assessment and earlier treatment. All participants were also genotyped for the drug metabolizing enzymes CYP2D6 and CYP2C19. Blood samples were stored in biobank for other analyses linked to prognostic markers. The patient cohort will now be followed up with a review of medical records and extraction of register data for a period of 5 years after their participation in the original study. The purpose of the study is to improve treatment and increase knowledge about long-term prognosis in difficult-to-treat depression. This is done by examining symptom profiles, monitoring clinical course and suicidality, and examining prognostic markers.

Outcome Measures
Primary Outcomes (7)
Suicide attempt and suicide
The frequency of suicide attempts and completed suicides in the patient sample over the follow-up period of 5 years
5 years follow-up after baseline visit.
Clinical course of depression
Course of depressive disorder during the follow-up period measured by information from medical records, where the reserach psychiatrist makes an assessment dichotomized as improved or not improved based on the available information.
5 years follow-up after baseline visit
Comparison of diagnostic assessment for personality disorders
Comparison of frequency of DSM-IV-TR personality disorders and ICD-11 personality disorders in the sample. ICD-11 personality disorders will also be divided into degree of difficulty as well as which specifiers of prominent traits are present in the population of difficult-to-treat depression
Baseline data and 5 years follow-up from inclusion.
Course and diagnostic characteristics of bipolar disorder
Historical order of diagnoses before bipolar diagnosis and the development of diagnostic assessment during follow-up as well as personality assessment according to DSM-IV and ICD-11.
Baseline data and 5 years follow-up after inclusion.
Results from pharmacological counseling for CYP2D6UM och CYP2D6PM
Change in score for Montgomery Ã…sberg Depression Rating Scale from week 0 to 8 (total of 9 weeks) during pharmacological counseling. Data from medical records for 5 years follow-up will be used to investigate adherence to recommendations during pharmacologic counseling and in a long term perspective.
Nine weeks of pharmacological counseling after baseline and 5 years follow-up from baseline visit
Prediction of long-term prognosis of depressive symptom profiles
Data on clinical outcome over 5 years follow-up for depressive symptom profiles with specific focus on anhedonic symtom profile derived from the Comprehensive Psychopatholocial Rating Scale (CPRS) and depression characteristics.
5 years follow-up from baseline visit
Course of disease related to dopamine D3 receptor and other biomarkers
The relationship between the course of depressive disorder and biomarkers including dopamine D3 receptor, other biomarkers of dopaminergic function, inflammation and other types of biomarkers
5 years follow-up from baseline visit
Interventions
No intervention is used.
