Dataset Information

Canadian clinical practice guidelines for the management of anxiety, posttraumatic stress and obsessive-compulsive disorders.

ABSTRACT:

Background

Anxiety and related disorders are among the most common mental disorders, with lifetime prevalence reportedly as high as 31%. Unfortunately, anxiety disorders are under-diagnosed and under-treated.

Methods

These guidelines were developed by Canadian experts in anxiety and related disorders through a consensus process. Data on the epidemiology, diagnosis, and treatment (psychological and pharmacological) were obtained through MEDLINE, PsycINFO, and manual searches (1980-2012). Treatment strategies were rated on strength of evidence, and a clinical recommendation for each intervention was made, based on global impression of efficacy, effectiveness, and side effects, using a modified version of the periodic health examination guidelines.

Results

These guidelines are presented in 10 sections, including an introduction, principles of diagnosis and management, six sections (Sections 3 through 8) on the specific anxiety-related disorders (panic disorder, agoraphobia, specific phobia, social anxiety disorder, generalized anxiety disorder, obsessive-compulsive disorder, and posttraumatic stress disorder), and two additional sections on special populations (children/adolescents, pregnant/lactating women, and the elderly) and clinical issues in patients with comorbid conditions.

Conclusions

Anxiety and related disorders are very common in clinical practice, and frequently comorbid with other psychiatric and medical conditions. Optimal management requires a good understanding of the efficacy and side effect profiles of pharmacological and psychological treatments.

Project description:ObjectiveTo compare adverse events (AEs), suicidality, and AE-related discontinuation in double-blind, placebo-controlled trials of pediatric patients with obsessive-compulsive disorder (OCD) and anxiety disorders treated with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs).MethodMEDLINE, PubMed, Web of Science, PsycINFO, and Embase were searched for peer-reviewed, English-language articles from inception through March 1, 2019. We identified prospective, randomized SSRI and SNRI studies in patients <18 years of age with OCD or generalized, separation, or social anxiety disorders. AE rates were extracted and medication-placebo differences were examined using Bayesian hierarchical models, then posterior estimates of relative risk (RR) were determined for each AE by medication class and disorder.ResultsData were included from 18 trials (2,631 patients) and 7 medications (16 SSRI and 4 SNRI trials). Compared with placebo, SSRIs were associated with a greater likelihood of AE-related discontinuation (RR 3.59, credible interval [CrI] 0.019-0.067, p = .0003), activation (RR 2.39, CrI 0.048-0.125, p = .003), sedation (RR 1.94, CrI 0.035-0.157, p = .002), insomnia (RR 1.93, CrI 0.040-0.149, p = .001), abdominal pain (RR 1.53, CrI 0.032-0.164, p = .005), and headache (RR 1.24, CrI 0.003-0.139, p = .04). Activation was more common with SSRIs (versus SNRIs, RR 1.32, CrI 0.018-0.114, p = .007). Neither SSRIs nor SNRIs were associated with treatment-emergent suicidality.ConclusionIn pediatric OCD and anxiety disorders, SSRIs (compared with placebo) are associated with distinct AEs and greater AE-related discontinuation, although their tolerability does not differ between anxiety disorders and OCD. Compared with SNRIs, SSRIs are more likely to produce activation. Class-related AEs are important for clinicians to consider, particularly in light of data suggesting differences in class-related efficacy. Whereas SSRIs are superior to SNRIs and the treatment of choice for anxiety, for youths who become activated on SSRIs, SNRIs might represent a good second choice given their reported efficacy and lower risk of activation.

Project description:BackgroundAnxiety, obsessive-compulsive, and stress-related disorders frequently co-occur, and patients often present symptoms of several domains. Treatment involves the use of selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs), but data on comparative efficacy and acceptability are lacking. We aimed to compare the efficacy of SSRIs, SNRIs, and placebo in multiple symptom domains in patients with these diagnoses over the lifespan through a 3-level network meta-analysis.Methods and findingsWe searched for published and unpublished randomized controlled trials that aimed to assess the efficacy of SSRIs or SNRIs in participants (adults and children) with diagnosis of any anxiety, obsessive-compulsive, or stress-related disorder in MEDLINE, PsycINFO, Embase, and Cochrane Library from inception to 23 April 2015, with an update on 11 November 2020. We supplemented electronic database searches with manual searches for published and unpublished randomized controlled trials registered in publicly accessible clinical trial registries and pharmaceutical companies' databases. No restriction was made regarding comorbidities with any other mental disorder, participants' age and sex, blinding of participants and researchers, date of publication, or study language. The primary outcome was the aggregate measure of internalizing symptoms of these disorders. Secondary outcomes included specific symptom domains and treatment discontinuation rate. We estimated standardized mean differences (SMDs) with 3-level network meta-analysis with random slopes by study for medication and assessment instrument. Risk of bias appraisal was performed using the Cochrane Collaboration's risk of bias tool. This study was registered in PROSPERO (CRD42017069090). We analyzed 469 outcome measures from 135 studies (n = 30,245). All medications were more effective than placebo for the aggregate measure of internalizing symptoms (SMD -0.56, 95% CI -0.62 to -0.51, p < 0.001), for all symptom domains, and in patients from all diagnostic categories. We also found significant results when restricting to the most used assessment instrument for each diagnosis; nevertheless, this restriction led to exclusion of 72.71% of outcome measures. Pairwise comparisons revealed only small differences between medications in efficacy and acceptability. Limitations include the moderate heterogeneity found in most outcomes and the moderate risk of bias identified in most of the trials.ConclusionsIn this study, we observed that all SSRIs and SNRIs were effective for multiple symptom domains, and in patients from all included diagnostic categories. We found minimal differences between medications concerning efficacy and acceptability. This three-level network meta-analysis contributes to an ongoing discussion about the true benefit of antidepressants with robust evidence, considering the significantly larger quantity of data and higher statistical power when compared to previous studies. The 3-level approach allowed us to properly assess the efficacy of these medications on internalizing psychopathology, avoiding potential biases related to the exclusion of information due to distinct assessment instruments, and to explore the multilevel structure of transdiagnostic efficacy.
