Avaliação de propriedades psicométricas e de resultados da aplicação da versão brasileira do \'Mini International Neuropsychiatric Interview - TRACKING\' em usuários da Estratégia de Saúde da Família acompanhados com ou sem cuidado colaborativo em saúde mental / Evaluation of psychometric properties and results from the application of the Brazilian version of the \'Mini International Neuropsychiatric Interview - TRACKING\' in users of the Family Health Strategy accompanied with or without collaborative care in mental healthLeonardo Moscovici 23 August 2013 (has links)
Objetivos: Estudar a confiabilidade e validade de uma versão brasileira dos módulos Episódio Depressivo Maior (EDM) e Transtorno de Ansiedade Generalizado (TAG) do Mini International Neuropsychiatric Interview TRACKING (MINI-TRACKING); comparar a evolução de pacientes com diagnóstico de EDM e TAG seguidos por equipes de Estratégia de Saúde da Família (ESF) com acesso ao modelo de Cuidado Colaborativo (CC) em Saúde Mental versus um grupo de pacientes seguidos por equipes sem acesso ao CC. Metodologia: O estudo envolveu quatro equipes de ESF vinculadas à Faculdade de Medicina de Ribeirão Preto (FMRP), sendo duas com acesso ao CC e duas sem CC. Um total de 147 pacientes foram entrevistados com o objetivo de rastrear transtornos mentais com a aplicação do WHO-5 e do COOP-WONCA Quadro Sentimentos. Após a confirmação diagnóstica de EDM e/ou TAG, com a entrevista MINI, 42 pacientes foram selecionados e concordaram em participar da pesquisa. Estes pacientes foram acompanhados por doze meses por um médico de família (MF), que aplicou periodicamente a cada oito a doze semanas os módulos EDM e/ou TAG do MINI-TRACKING. Para avaliação da fidedignidade e da validade concorrente, um psiquiatra (cego quanto ao diagnóstico do MF e quanto a qual equipe seguia o paciente) aplicou, com intervalo máximo de 72h do MF, os mesmos módulos do MINI-TRACKING, o PHQ-9 e/ou o GAD-7. Resultados: Não foi encontrada diferença estatisticamente significativa entre os pacientes das equipes com e sem CC no que se refere as características clínicodemográficas. Os itens individuais dos dois módulos do MINI-TRACKING mostraram boa fidedignidade inter-avaliadores (Kappa entre 0,78 e 0,98), bem como seus escores totais (Coeficiente Intra-classe de 0,996 e 0,993 para EDM e TAG, respectivamente). Os módulos EDM e TAG mostraram também boa validade concorrente com as escalas PHQ-9 e GAD-7 (coeficiente de Pearson 0,994 e 0,976, respectivamente). Trinta pacientes (quinze de equipes com CC e 15 de equipes sem CC) completaram as cinco avaliações no decorrer de um ano de seguimento. A ANOVAmr destes pacientes mostrou diferenças significativas no fator tempo e na interação tempo x intervenção, com diminuição significativamente maior dos escores do MINI-TRACKING nos pacientes seguidos pelas equipes com CC. Conclusão: Os módulos EDM e TAG do MINI-TRACKING são uma opção confiável para o seguimento de pacientes com estes diagnósticos. Este estudo também mostrou, de forma preliminar, que o CC em saúde mental é uma estratégia eficaz na redução de sintomas dos pacientes com EDM e TAG na Atenção Primária. / Objectives: To study the reliability and validity of a Brazilian version of the Mini International Neuropsychiatric Interview - TRACKING (MINI-TRACKING) modules for Major Depressive Episode (MDE) and Generalized Anxiety Disorder (GAD); To compare the outcomes of patients diagnosed with MDE and GAD followed by teams of the Family Health Strategy (FHS) with access to the Mental Health Collaborative Care model (CC) versus a group of patients followed by teams without access to CC. Methodology: The study involved four FHS teams of the Faculty of Medicine of Ribeirão Preto (FMRP), two of them with access to CC and two without it. A total of 147 patients were tracked for mental disorders with the application of the WHO-5 and the COOP-WONCA Chart Feelings. After confirming the diagnosis of MDE and/or GAD using the MINI interview, 42 patients were selected and agreed to participate. These patients were followed for twelve months by a family physician (FP), who applied regularly every eight to twelve weeks the MDE and/or the GAD MINI-TRACKING modules. To assess the reliability and concurrent validity, a psychiatrist (blind to the diagnosis and to which team the patient was followed) also applied the same modules of the MINI-TRACKING, the PHQ-9 and/or the GAD-7, with a maximum interval of 72 hours of the FP. Results: There was no statistically significant difference between the patients with and without CC teams regarding demographic and clinical characteristics. The individual items of the two MINI-TRACKING modules showed good inter-rater reliability (kappa between 0.78 and 0.98), as well as their total scores (Intra-class coefficient of 0.996 and 0.993 for MDE and GAD, respectively). The MDE and GAD modules also showed good concurrent validity with PHQ-9 and GAD-7 scales (Pearson coefficient 0.994 and 0.976, respectively). Thirty patients (fifteen with CC and 15 without CC) completed the five assessments during one year of follow up. The repeated-measures analysis of variance (rmANOVA) showed significant differences in the time factor and the interaction time x intervention, decrease significantly higher of the MINI-TRACKING scores in the patients followed by teams with CC. Conclusion: MINI-TRACKING MDE and GAD modules are a reliable option for following patients with these diagnoses. This study also showed, preliminarily, that CC in Mental Health is an effective strategy in reducing symptoms in Primary Care patients with MDE and GAD.

Avaliação da eficácia clínica-cognitiva e segurançaa da estimulação magnética transcraniana com bobina h1 no tratamento de episódios de depressão bipolar / Evaluation clinical, cognitive and safety in the treatment of bipolar depression with h1-coil repetitive transcranial magnetic stimulationMartin Luiz Myczkowski 18 April 2018 (has links)
INTRODUÇÃO: A depressão bipolar (DB) é uma condição altamente prevalente associada a déficits cognitivos que persistem mesmo na fase eutímica da doença. Os tratamentos farmacológicos para DB podem agravar ainda mais o comprometimento cognitivo, destacando a necessidade de desenvolver intervenções que tenham segurança cognitiva. A Estimulação Magnética Transcraniana \'profunda\' através de bobina H1 (EMTr-H1) é uma nova modalidade de neuromodulação com eficácia estabelecida para a depressão unipolar. Este é o primeiro estudo em caráter exploratório e controlado por placebo, a avaliar os efeitos cognitivos da EMTr-H1 em pacientes com DP resistente ao tratamento. MÉTODO: Quarenta e três pacientes foram randomizados para receber 20 sessões de EMTr-H1 ativa (55 séries de estímulos direcionados à área pré frontal esquerda, a 18Hz e 120% de intensidade do limiar motor em repouso) ou de EMTr-H1 placebo, em um ensaio duplo-cego, controlado por estimulação simulada. Uma bateria de avaliação neuropsicológica contendo 20 testes cognitivos, agrupados em seis domínios cognitivos (atenção e velocidade de processamento, memória de trabalho e função executiva, controle inibitório, linguagem, memória verbal imediata e memória verbal de longo prazo), foi realizada imediatamente antes do início das sessões de EMTr-H1 (avaliação basal - semana 0) e após 4 (20ª e última sessão - semana 4) e 8 semanas (seguimento de mais 4 semanas sem novas intervenções - semana 8) do início deste estudo. Sintomas depressivos e maníacos também foram avaliados. A medida clínica de desfecho primária foi à redução percentual do escore basal da Escala de Hamilton para avaliação da depressão com 17 itens (HDRS-17) após 20 sessões de estimulação (semana 4). A medida de segurança durante as 8 semanas incluiu, além da Escala de Mania de Young (YMRS) para avaliar ciclagens de mania emergentes possivelmente relacionados ao tratamento (TEMS), principalmente, uma bateria de testes de avaliação neuropsicológica, que avaliou a possibilidade de sequelas e/ou reparações cognitivas em relação ao método. RESULTADOS: Entre os 50 pacientes que iniciaram o estudo, 2 do grupo placebo EMTr-H1 e 5 do grupo EMTr-H1 ativo, desistiram de participar do ensaio e não completaram as avaliações, sendo excluídos da análise (\"dropouts\"), portanto, 43 pacientes finalizaram o estudo. O grupo EMTr-H1 ativo apresentou uma resposta clinica antidepressiva superior ao placebo na semana 4 (diferença favorecendo EMTr-H1=4,88; 95% CI=0,43 a 9,32, p=0,03), mas não nas semanas de seguimento. Houve também uma tendência para maiores taxas de resposta no grupo ativo (48%) vs. placebo (24%) (OR=2,92; 95% CI=0,87 a 9,78, p=0,08). As taxas de remissão não foram estatisticamente diferentes. Não foram observados episódios de TEMS. Foi constatada uma melhoria cognitiva em relação a todos os domínios cognitivos, mas que ocorreu ao longo do tempo e independentemente do grupo de intervenção e da melhora da depressão. Não foi encontrada correlação entre a melhora da depressão e da cognição. LIMITAÇÕES: Ausência de um grupo controle saudável. CONCLUSÕES: A EMTr \'profunda através da bobina H1 é uma terapia antidepressiva de adição potencialmente eficaz e bem tolerada em pacientes com depressão bipolar resistente que receberam farmacoterapia adequada. Os resultados cognitivos deste estudo exploratório fornecem evidências sobre a segurança cognitiva da EMTr-H1 para pacientes com DB. Não foram observados supostos efeitos deletérios e nem pró-cognitivos da EMTr-H1 na DB, mas pesquisas adicionais se fazem necessárias por meio de outros estudos similares e que contemplem a cognição / INTRODUCTION: Bipolar depression (BD) is a highly prevalent condition associated with marked cognitive deficits that persist even in the euthymic phase of the illness. Pharmacological treatments for BD might further aggravate cognitive impairment, highlighting the need of developing interventions that have cognitive safety. \'Deep\' H1-coil Transcranial Magnetic Stimulation (H1-rTMS) is a new modality of neuromodulation with established efficacy for unipolar depression. This is the first exploratory, placebo-controlled study evaluating the cognitive effects of rTMS in patients with treatment-resistant bipolar depression. METHODS: Fourty-three patients were randomized to receive 20 sessions of active (55 trains directed to the left prefrontal area, 18Hz, 120% resting motor threshold intensity) or sham rTMS within a double-blind, sham-controlled trial. A battery of neuropsychological assessment with 20 cognitive tests, grouped in 6 domains (attention and processing speed, working memory and executive function, inhibitory control, language, immediate verbal memory, and long-term verbal memory) was performed at baseline (week 0) and after 4 (20th and last session - week 4) and 8 weeks (follow-up of 4 weeks without further intervention - week 8) of trial onset. Depressive and manic symptoms were also evaluated. The primary clinical outcome measure was percentage reduction of the baseline score of the Hamilton Scale for assessment of depression with 17 items (HDRS-17) after 20 stimulation sessions (week 4). The safety measure during the 8 weeks included, in addition to the Young Mania Scale (YMRS) wich evaluated the emergent mania possibly related to treatment (TEMS), mainly a battery of neuropsychological evaluation tests, which evaluated the possibility of sequelae or cognitive repairs in relation to the method. RESULTS: Among the 50 patients who started the study, 2 of the sham H1-rTMS group and 5 of the active H1-rTMS group, gave up participating in the trial and did not complete the assessments, being excluded from the analysis (\"dropouts\"), therefore, 43 patients completed the study. The active H1-rTMS had an antidepressant clinical response higher than placebo at week 4 (difference favoring H1-rTMS=4.88; 95% CI=0.43 to 9.32, p=0.03) but not at weeks of follow-up. There was also a trend for greater response rates in the active (48%) vs. sham (24%) groups (OR=2.92; 95% CI=0.87 to 9.78, p=0.08). Remission rates were not statistically different. No TEMS episodes were observed. A cognitive improvement was observed in all cognitive domains, but it occurred over time and independently of the intervention group and depression improvement. No correlation was found between improvement of depression and cognition. LIMITATIONS: Absence of healthy control group. CONCLUSION: Deep H1-rTMS is a potentially effective and well-tolerated add-on antidepressive therapy in resistant bipolar depressed patients to received adequate pharmacotherapy. The cognitive results of this exploratory study provide evidence on the cognitive safety of H1-coil rTMS for BD patients. No deleterious or pro-cognitive effects of H1-rTMS in BD have been observed, but further research is needed through other similar studies that contemplate cognition

BDNF/TRKB, volume hippocampique et réponse aux antidépresseurs dans le trouble dépressif unipolaire / BDNF/TRKB, hippocampal volume and antidepressant reponse in major depressive disorderColle, Romain 05 January 2016 (has links)
Introduction : Issus des données animales, les modèles neurotrophiniques du mécanisme d’action des médicaments antidépresseurs pourraient permettre d’identifier chez l’Homme des biomarqueurs prédictifs de la réponse et de la rémission sous antidépresseurs. Nous évaluons l’intérêt clinique, chez les patients souffrant de trouble dépressif caractérisé unipolaire, de 11 biomarqueurs : polymorphismes nucléotidiques simples (SNP) du Brain Derived Neurotrophic Factor (BDNF) et de son récepteur, le Récepteur Tyrosine-Kinase B (TRKB), taux plasmatiques de BDNF et volume hippocampique sur la réponse/rémission sous antidépresseurs. Méthode : Les données originales de ce travail sont issues de la cohorte METADAP. Il s’agit d’une cohorte, prospective, multicentrique incluant 624 patients présentant un épisode dépressif caractérisé dans le cadre d’un trouble dépressif caractérisé unipolaire et nécessitant l’introduction d’un traitement antidépresseur. Le traitement antidépresseur est prescrit de façon naturaliste (tous antidépresseurs commercialisés en France). Les patients sont évalués 1, 3 et 6 mois après l’introduction du traitement antidépresseur. Les biomarqueurs étudiés sont les polymorphismes Val66Met du BDNF et 8 SNP du TRKB et les dosages de BDNF plasmatiques. Une étude ancillaire est menée à partir de 63 patients ayant bénéficié d’Imagerie par Résonnance Magnétique cérébrale réalisée en pratique courante à l’inclusion de cette cohorte afin d’évaluer les volumes hippocampiques. Résultats : 1) Une revue de la littérature met en évidence une association entre la réponse aux antidépresseurs et 12 SNP du BDNF/TRKB sur 242 étudiés, ainsi qu’une association entre allèle Met du polymorphisme Val66Met du BDNF et meilleure réponse sous antidépresseurs chez les patients asiatiques. 2) Nos données ne mettent pas en évidence d’impact de 8 SNP du TRKB sur la réponse/rémission après traitement antidépresseur, mais un effet différentiel du Val66Met du BDNF selon la classe de traitement antidépresseur. 3) L’étude des dosages de BDNF plasmatiques n’est pas concluante. 4) Concernant les volumes hippocampiques, notre méta-analyse montre que des volumes hippocampiques moindres prédisent une moindre réponse/rémission après traitement antidépresseur. 5) Concernant les liens entre les biomarqueurs étudiés, nous ne mettons pas en évidence d’association. Conclusion : Sur les 11 biomarqueurs étudiés, seuls 2 pourraient présenter une utilité en pratique clinique. Si nos travaux étaient répliqués, le polymorphisme Val66Met du BDNF et le volume hippocampique pourraient conduire à orienter le choix des antidépresseurs dans le traitement des épisodes dépressifs caractérisés. Malgré une littérature cohérente chez l’Animal, nous n’avons pas mis en évidence, dans l’échantillon étudié, de lien entre les biomarqueurs génétiques étudiés et les volumes hippocampiques. Nous poursuivons ce travail d’évaluation des biomarqueurs neurotrophiniques et neurogéniques avec des méthodes d’évaluations nouvelles : séquençage nouvelle génération pour la génétique et imagerie multimodale (acquisition répétée d’IRM structurelle, fonctionnelle et de diffusion) de l’hippocampe. Nous évaluerons également de nouveaux biomarqueurs. / Introduction: developed with Animal preclinical approachs, neurtrophinic and neurogenic models of antidepressant mechanism of action lead to identify biomarkers in Human which could be predict antidepressant response and remission in depressed patients. We assess the clinical benefit of 11 biomarkers in depressed patients: Brain Derived Neurotrophic Factor (BDNF) and its receptor Tyrosine Receptor -Kinase B (TRKB), Plasma BDNF and Hippocampal volumes to predict antidepressant response/remission. Methods: The original research data of this work are from METADAP cohort. It is a prospective, multicentric cohort including 624 patients with a diagnosis of major depressive disorder and a current major depressive episode at the start of the index antidepressant treatment. Antidepressant treatment is prescribed in naturalistic conditions (all commercialized antidepressant in France). Patient are assessed 1, 3 and 6 months after the start of antidepressant treatment. Studied biomarkers are BDNF Val66Met polymorphism, 8 TRKB SNP and plasma BDNF. Ancillary study are done with 63 patients which benefit in clinical practice of Magnetic Resonnance (MRI) at the inclusion of the cohort. Results: 1) A review of literature reports associations between antidepressant efficacy and 12 BDNF/TRKB SNP on 242 studied SNP and an association with Met allele of Val66Met BDNF polymorphism and a best antidepressant efficacy in Asian patients. 2) Our original data show no impact of 8 TRKB SNP on antidepressant response remission but a differential effect of Val66Met BDNF polymorphism depending on antidepressant treatment class. 3) Plasma BDNF study is not conclusive. 4) Concerning hippocampal volumes, our meta-analysis show that smaller hippocampal volumes predict lower response/remission rate after antidepressant treatment. 5) No association is found between studied biomarkers. Conclusion: 2 of the 11 studied biomarkers could be useful in clinical practice. After replication of our results, Val66Met polymorphism could lead to personalized antidepressant prescription in major depressive disorder. Although the animal prelinical littérature appar strong, we dont report association between genetic biomarker and hippocampal volume in ours ample. We will assess neurotrophinic and neurogenic biomarkers with new methods: next generation sequencing for genetic, multimodal imaging (repeated structural, functional and diffusion MRI) of hippocampus. We also will assess new biomarkers.

Des soins de qualité pour la dépression en première ligne : une contribution à l’amélioration de l’état de santé de la population québécoiseDuhoux, Arnaud 04 1900 (has links)
Contexte
De nombreuses études, utilisant des indicateurs de qualité variés, ont démontré que la qualité des soins pour la dépression n’est pas optimale en première ligne. Peu de ces études ont examiné les facteurs associés à la réception d’un traitement adéquat, en particulier en tenant compte simultanément des caractéristiques individuelles et organisationnelles. L'association entre un traitement adéquat pour un épisode dépressif majeur (EDM) et une amélioration des symptômes dépressifs n'est pas bien établie dans des conditions non-expérimentales. Les objectifs de cette étude étaient de : 1) réaliser une revue systématique des indicateurs mesurant la qualité du traitement de la dépression en première ligne ; 2) estimer la proportion de patients souffrant d’EDM qui reçoivent un traitement adéquat (selon les guides de pratique clinique) en première ligne ; 3) examiner les caractéristiques individuelles et organisationnelles associées à l’adéquation du traitement pour la dépression ; 4) examiner l'association entre un traitement minimalement adéquat au cours des 12 mois précédents et l'évolution des symptômes dépressifs à 6 et 12 mois.
Méthodes
La littérature sur la qualité du traitement de la dépression a été examinée en utilisant un ensemble de mots-clés (« depression », « depressive disorder », « quality », « treatment », « indicator », « adequacy », « adherence », « concordance », « clinical guideline » et « guideline ») et « 360search », un moteur de recherche fédérée. Les données proviennent d'une étude de cohorte incluant 915 adultes consultant un médecin généraliste, quel que soit le motif de consultation, répondant aux critères du DSM-IV pour l’EDM dans la dernière année, nichés dans 65 cliniques de première ligne au Québec, Canada. Des analyses multiniveaux ont été réalisées.
Résultats
Bien que majoritairement développés à partir de guides de pratique clinique, une grande variété d'indicateurs a été observée dans la revue systématique de littérature. La plupart des études retenues ont utilisé des indicateurs de qualité rudimentaires, surtout pour la psychothérapie. Les méthodes utilisées étaient très variées, limitant la comparabilité des résultats. Toutefois, quelque soit la méthode choisie, la plupart des études ont révélé qu’une grande proportion des personnes souffrant de dépression n’ont pas reçu de traitement minimalement adéquat en première ligne.
Dans notre échantillon, l’adéquation était élevée (> 75 %) pour un tiers des indicateurs de qualité mesurés, mais était faible (< 60 %) pour près de la moitié des mesures. Un peu plus de la moitié de l'échantillon (52,2 %) a reçu au moins un traitement minimalement adéquat pour la dépression. Au niveau individuel, les jeunes adultes (18-24 ans) et les personnes de plus de 65 ans avaient une probabilité moins élevée de recevoir un traitement minimalement adéquat. Cette probabilité était plus élevée pour ceux qui ont un médecin de famille, une assurance complémentaire, un trouble anxieux comorbide et une dépression plus sévère. Au niveau des cliniques, la disponibilité de la psychothérapie sur place, l'utilisation d'algorithmes de traitement, et le mode de rémunération perçu comme adéquat étaient associés à plus de traitement adéquat. Les résultats ont également montré que 1) la réception d'au moins un traitement minimalement adéquat pour la dépression était associée à une plus grande amélioration des symptômes dépressifs à 6 et à 12 mois; 2) la pharmacothérapie adéquate et la psychothérapie adéquate étaient toutes deux associées à de plus grandes améliorations dans les symptômes dépressifs, et 3) l'association entre un traitement adéquat et l'amélioration des symptômes dépressifs varie en fonction de la sévérité des symptômes au moment de l'inclusion dans la cohorte, un niveau de symptômes plus élevé étant associé à une amélioration plus importante à 6 et à 12 mois.
Conclusions
Nos résultats suggèrent que des interventions sont nécessaires pour améliorer la qualité du traitement de la dépression en première ligne. Ces interventions devraient cibler des populations spécifiques (les jeunes adultes et les personnes âgées), améliorer l'accessibilité à la psychothérapie et à un médecin de famille, et soutenir les médecins de première ligne dans leur pratique clinique avec des patients souffrant de dépression de différentes façons, telles que le développement des connaissances pour traiter la dépression et l'adaptation du mode de rémunération. Cette étude montre également que le traitement adéquat de la dépression en première ligne est associé à une amélioration des symptômes dépressifs dans des conditions non-expérimentales. / Background
Numerous studies, using a variety of quality indicators, highlight an important gap in the quality of care for depression in primary care. Few of these studies examined factors associated with receiving adequate treatment, particularly with a simultaneous consideration of individual and organizational characteristics. The association between adequate treatment for a Major Depressive Episode (MDE) and improvements in depressive symptoms is not well established in naturalistic practice conditions. The objectives of this study were to i) systematically review indicators used to measure the quality of depression treatment in primary care, ii) estimate the proportion of primary care patients with a MDE who receive adequate treatment, iii) examine the individual and organizational characteristics associated with the receipt of minimally adequate treatment for depression, iv) examine the association between receiving minimally adequate treatment for MDE (i.e. according to clinical guidelines) in the previous 12 months and evolution of depressive symptoms at 6 and 12 months.
Methods
The literature on the quality of depression treatment was reviewed using a set of keywords (depression, depressive disorder, quality, treatment, indicator, adequacy, adherence, concordance, clinical guideline and guideline) and « 360search », a federated search engine. Data were obtained from a cohort study including 915 adults consulting a general practitioner (GP), regardless of the motive of consultation, meeting DSM-IV criteria for previous-year MDE, and nested within 65 primary care clinics in Quebec, Canada. Multilevel analyses were conducted.
Results
Though mostly based on recommendations from clinical practice guidelines, a great variety of indicators were observed. Most studies used rudimentary indicators to measure the quality of depression treatment, especially for psychotherapy. Studies also differed greatly with respect to the methods used, thus limiting the comparability of results. However, whatever the chosen method, most studies reveal that a large proportion of people with depression do not receive minimally adequate treatment in primary care settings.
In our sample, adherence to guidelines was high (> 75 %) for one third of the quality indicators that were measured but was low (< 60 %) for nearly half of the measures. Just over half of the sample (52.2 %) received at least one minimally adequate treatment for depression. At the individual level, young adults (18-24) et older people (>65) had a lower probability of receiving at least one minimally adequate treatment. This probability was higher for people with a family physician, a supplementary insurance coverage, a comorbid anxiety disorder and a more severe depression. At the clinic level, the availability of psychotherapy on-site, the use of treatment algorithms, and the mode of remuneration perceived as adequate were associated with more adequate treatment.
Results also showed that i) receiving at least one minimally adequate treatment for depression was associated with greater improvements in depression symptoms at 6 and at 12 months; ii) adequate pharmacotherapy and adequate psychotherapy were both associated with greater improvements in depression symptoms, and iii) the association between adequate treatment and improvement in depression symptoms varied as a function of severity of symptoms at the time of inclusion in the cohort with worse symptoms at the time of inclusion being associated with greater reductions at 6 and 12 months.
Conclusions
Our findings suggest that interventions are needed to increase the quality of depression treatment in primary care. These interventions should target specific populations (i.e. the younger adults and the elderly), enhance accessibility to psychotherapy and to a regular family physician, and support primary care physicians in their clinical practice with patients suffering from depression in different ways such as developing knowledge to treat depression and adapting mode of remuneration. This study also shows that adequate treatment for depression is associated with improvements in depressive symptoms in naturalistic primary care practice conditions.

Results also showed that i) receiving at least one minimally adequate treatment for depression was associated with greater improvements in depression symptoms at 6 and at 12 months; ii) adequate pharmacotherapy and adequate psychotherapy were both associated with greater improvements in depression symptoms, and iii) the association between adequate treatment and improvement in depression symptoms varied as a function of severity of symptoms at the time of inclusion in the cohort with worse symptoms at the time of inclusion being associated with greater reductions at 6 and 12 months.
Conclusions
Our findings suggest that interventions are needed to increase the quality of depression treatment in primary care. These interventions should target specific populations (i.e. the younger adults and the elderly), enhance accessibility to psychotherapy and to a regular family physician, and support primary care physicians in their clinical practice with patients suffering from depression in different ways such as developing knowledge to treat depression and adapting mode of remuneration. This study also shows that adequate treatment for depression is associated with improvements in depressive symptoms in naturalistic primary care practice conditions.
