Objective: To evaluate the compliance, persistence and costs of the treatment of major depressive disorder (MDD) in the setting of Primary Care, placing emphasis on the different aspects of those patients with an initial suboptimal response to antidepressant treatment., Design: A retrospective observational study using the population registers of Badalona Healthcare Services. The inclusion criteria consisted of; age ≥18 years, initial episode during 2008-2009, and to be on antidepressant treatment for at least 8 weeks after the first prescription. The follow-up was 12 months. Two study groups were formed, patients with suboptimal response, and remission., Main Measurements: Sociodemographic data, compliance and adherence to treatment, health costs (direct and indirect)., Results: A total of 2,260 subjects were analysed (mean age 58.8 years, 74% women). Just under half (42.7%, 95% CI; 40.0-46.4%) had a suboptimal response to the treatment. These patients had a higher mean age, a higher proportion of women, and pensioners, as well as higher comorbidity, compared to the remission group. They also had poorer compliance percentages (65.1% vs. 67.7%) and treatment persistence at 12 months (31.8% vs. 53.2%), respectively, P<.001. The annual health costs were, 826.1€ for patients with a suboptimal response vs. 451.2€ in patients in remission; loss of productivity 1,842.0€ vs. 991.4€, respectively; P<.001. The factors associated to a suboptimal response were; lack of compliance (OR=1.7), years with the disorder (OR=1.2), age (OR=1.1) and presence of comorbidity (OR=1.1)., Conclusions: The patients with an initial suboptimal response to antidepressant treatment had a higher comorbidity, lower therapeutic compliance, and incurred higher total costs, particularly in losses in work productivity., (Copyright © 2012 Elsevier España, S.L.

Objective: To determine the social cost and burden of depression in the city of Sabadell (Barcelona, Spain) in 2007 and 2008., Method: The social cost of depression was calculated using the prevalence approach, based on information obtained in the development of the European Project Against Depression (EAAD). The results referred to the cost of public resources used, and the sources came from the appropriate official registers., Results: The direct public cost of depression in the city of Sabadell was € 9,155,620 in 2007 and € 9,304,706 in 2008. The relative weight of primary care visits and the use of drugs accounted for more than 85% of direct costs. In the section of indirect costs, the cost of permanent work disability could not be obtained. Indirect costs amounted to € 9,720,225 in 2007 and € 9,763,541 in 2008. In both years, the highest weight corresponded to temporary work disability reaching € 8,561,962 and € 7,333,181, respectively., Conclusions: Depression has a substantial economic impact on the health system because it is associated with high direct public costs. However, the lack of knowledge of the cost associated with permanent work disability is a major limitation, as this cost category represents the highest percentage for this disorder., (Copyright © 2011 SESPAS.

Objective: To determinate the impact of comorbidity, resource use and cost (healthcare and lost productivity) on maintenance of remission of major depressive disorder in a Spanish population setting., Methods: We performed an observational, prospective, multicenter study using population databases. The inclusion criteria were age > or = 18 years, first depressive episode between January 2003 and March 2007, with antidepressant prescription >60 days after the first prescription and a follow-up of at least 18 months (study: 12 months; continuation: 6 months). Two subgroups were considered: patients with/without remission., Main Measures: sociodemographic data, episodes, resource utilization bands, healthcare costs (direct) and lost productivity (indirect). Logistic regression and analysis of covariance (Bonferroni correction) were used for analysis., Results: A total of 4,572 patients were analyzed and 54.6% (95% confidence interval: 53.2-56.0%) were considered in remission. Patients in remission were younger (52.6 vs. 60.7), with a lower proportion of women (71.7% vs. 78.2%), and showed less general morbidity (6.2 vs. 7.7 episodes/year), lower resource utilization bands/year (2.7 vs. 3.0), fewer sick leave days (31.0 vs. 38.5) and shorter treatment duration (146.6 vs. 307.7 days); p<0.01. Lack of remission was associated with fibromyalgia (odds ratio [OR]=2.5), thyroid alterations (OR=1.3) and hypertension (OR=1.2); p<0.001. The annual healthcare cost was euro706.0 per patient in remission vs. euro1,108.3 without remission (p <0.001) and lost productivity was euro1,631.5 vs. euro2,024.2, respectively (p <0.001)., Conclusions: Patients not achieving remission showed higher morbidity, resources use, healthcare costs and, especially, productivity losses., (Copyright 2009 SESPAS.

Background: Data from the Ministry of Health show that in Chile in 2004, 17% of the population had some form of depression, and mood disorders are the tenth cause of disability-adjusted life years (DALY) loss., Aim: To determine consumption of antidepressants (ADs) in Chile from 1992 to 2004., Material and Methods: National sales data were obtained from the company IMS Health Chile and converted into defined daily doses (DDDs) per 1,000 inhabitants per day. Available ADs were classified in four pharmacological groups (i.e., serotonin-norepinephrine reuptake inhibitors, SNRLs; selective-serotonin reuptake inhibitors, SSRLs; tricyclic antidepressants, TCAs; and others). Total economic burden of ADs utilization and cost per DDDs were also calculated. Trends over time were analyzed using Pearson-R2., Results: Total ADs consumption in Chile measured by DDDs per 1,000 inhabitants per day (DHD) increased linearly (y =0.901x + 1.9129; R2 =0.9296; p <0.001) from 2.5 in 1992 to 11.7 in 2004 (total growth of 470.2%). SSRLs were the drug class with higher consumption, and fluoxetine the most commonly consumed antidepressant. SSRLs were the drugs that dominated the market representing 79% of the total drug consumption throughout the years. Total economic burden of ADs in Chile (total cost of DDDs consumed) increased from US$65.4 million in 2001 to US$74.6 million in 2004 (14% increase). Average cost per DDD of all AD increased linearly, however not significantly from US$ 0.94 in 2001 to US$ 1.04 in 2004 (y =0.0362x + 0.8784; R2 =0.7382; p =0,262)., Conclusions: DDDs per 1,000 inhabitants per day increased linearly over 470% from 1992-2004. SSRLs were the most commonly consumed drugs in Chile. Future research should evaluate the cost-effectiveness of antidepressants in Chile, comparing the results with drug utilization, and determining if unnecessary expenditures have been paid out.

Mental disorders mortality rates are low but they are extremely disabling so that the diagnosis and treatment of mental illness is an important task for public health and it is central in current therapy strategies and sanitary policy. The aim of this study is to analyse conditions influencing antidepressants and antipsychotics use in Spain from 1997 to 2004. Tryciclic antidepressants have been of first-choice in depression treatment for many years but their side effects profile are related to a lack of treatment adherence. Trying to increase tolerance, new antidepressants have been developed and research into new therapeutic uses is being done. These are some of the reasons causing an increase in medical utilization and costs. Medical boxes sold have increased from 14,14 million in 1997 to 26,76 million in 2004, meaning 168,61 and 447,11 million euros respectively. Antipsychotic use has been maintained, 11,74 million boxes in 1997 and 12,65 in 2004; however, there has been a rise in price from 61,84 to 317,46 million euros due to second generation antipsychotics prescription (mainly risperidone and olanzapine) Some conditions have contributed to current situation: increased number of diagnosed patients with depression and other mental disorders, new approved therapeutic uses and a rise in elderly people receiving new antipsychotic agents. Moreover, promotional marketing is causing an increase in new recently commercialised drugs use.

Objective: To assess if, in usual clinical practice, the patterns of use of new antidepressant are associated to different health resource utilisation., Design: Naturalistic, retrospective, observational study., Setting: Urban health center., Patients: DSM-IIIR diagnostic criteria of depressive disorder and treatment with a new antidepressant (n = 328)., Interventions: Information on resource utilisation was collected in those patients treated with fluoxetine (FLX), fluvoxamine (FLV) sertraline (SER), paroxetine (PAR) and venlafaxine (VLF). Direct, indirect and total costs were compared according to the different patterns of use (stable therapy, upward dose titration, switching or augmentation) and according to the initially prescribed antidepressant. The follow-up period was 6 months., Results: Direct and total daily costs of those patients with unestable therapy (upward dose titration, switching or augmentation) were 55% (p < 0.01) and 87% (p = 0.001) higher than for patients with stable therapy, respectively. Patients who initiated therapy on SER, VLF and PAR had 35% (p < 0.05), 80% (p < 0.05) and 37% (p < 0.05), respectively, higher average total costs per day than patients who initiated therapy with FLX. Regarding direct costs, patients who initiated therapy on SER and VLF had 48% (p < 0.001) and 58% (p < 0.05) higher average costs per day than patients who initiated therapy with FLX., Conclusions: New antidepressants show different patterns of use in a clinical practice setting, being FLX the agent more associated to a stable pattern of use. The pattern of use is associated to different health resource utilisation. Patients under stable therapy show lower health costs than those who need upward titration, switching or augmentation strategies. It is necessary to conduct randomized naturalistic studies to confirm these results.
