Predictors of abstinence maintenance after cocaine inpatient detoxification: A prospective study.

Cocaine is a highly addictive substance, and with no approved medication for cocaine use disorder (CUD), leading to a heavy burden. Despite validated psychosocial treatments, relapse rates after detoxification are very high in CUD. Few consistent factors can predict abstinence after detoxification. Our study, therefore, aimed at identifying factors predicting abstinence among CUD patients after inpatient detoxification. Eighty-one CUD inpatients were included during detoxification and characterized for clinical and sociodemographic data at baseline and at a follow-up of 3 months after discharge, including a standard measure of their abstinence duration from cocaine. We performed Cox univariate analyzes to determine the factors associated with abstinence maintenance, followed by a multivariate Cox regression to identify independent predictors. Abstinence maintenance was shorter in patients injecting cocaine (hazard ratio [HR] = 5.16, 95% confidence interval [CI]: 2.01-13.27, p < .001) and using cocaine heavily in the month before inclusion (HR = 1.03, 95% CI: 1.00-1.06, p = .046). Conversely, abstinence maintenance was longer in patients with longer inpatient detoxification stays (HR = 0.96, 95% CI: 0.94-0.99, p = .015) and prescribed with selective serotonin reuptake inhibitors (SSRIs) (HR = 0.30, 95% CI: 0.16-0.56, p < .001). Patients with severe CUD may require longer inpatient stays to achieve abstinence. Regarding SSRI prescription, more specific studies are needed to provide stronger recommendations about their use in clinical practice. Our findings suggest several modifiable factors to improve inpatient treatment response in CUD. As there are no specific recommendations about the optimal duration of inpatient stay, our results could pave the way for evidence-based guidelines.

Treatment of long COVID complicated by postural orthostatic tachycardia syndrome-Case series research.

Coronavirus disease 2019 (COVID-19) sequelae, also known as long COVID, can present with various symptoms. Among these symptoms, autonomic dysregulation, particularly postural orthostatic tachycardia syndrome (POTS), should be evaluated. However, previous studies on the treatment of POTS complicated by COVID-19 are lacking. Therefore, this study aimed to investigate the treatment course of long COVID complicated by POTS. The medical records of patients who complained of fatigue and met the criteria for POTS diagnosis were reviewed. We evaluated the treatment days, methods and changes in fatigue score, changes in heart rate on the Schellong test, and social situation at the first and last visits. Thirty-two patients with long COVID complicated by POTS were followed up (16 males; median age: 28 years). The follow-up period was 159 days, and the interval between COVID-19 onset and initial hospital attendance was 97 days. Some patients responded to β-blocker therapy. Many patients had psychiatric symptoms that required psychiatric intervention and selective serotonin reuptake inhibitor prescription. Changes in heart rate, performance status, and employment/education status improved from the first to the last visit. These outcomes were believed to be because of the effects of various treatment interventions and spontaneous improvements. Our study suggests that the condition of 94% of patients with POTS complicated by long COVID will improve within 159 days. Therefore, POTS evaluation should be considered when patients with long COVID complain of fatigue, and attention should be paid to psychological symptoms and the social context.

Age-Dependent Sex Differences in the Prevalence of Selective Serotonin Reuptake Inhibitor Treatment: A Retrospective Cohort Analysis.

Background: Antidepressants are among the most prescribed medications in the United States. The aim of this study was to explore the prevalence of antidepressant prescriptions and investigate sex differences and age-sex interactions in adults enrolled in the Right Drug, Right Dose, Right Time: Using Genomic Data to Individualize Treatment (RIGHT) study. Materials and Methods: We conducted a retrospective analysis of the RIGHT study. Using electronic prescriptions, we assessed 12-month prevalence of antidepressant treatment. Sex differences and age-sex interactions were evaluated using multivariable logistic regression and flexible recursive smoothing splines. Results: The sample consisted of 11,087 participants (60% women). Antidepressant prescription prevalence was 22.24% (27.96% women, 13.58% men). After adjusting for age and enrollment year, women had significantly greater odds of antidepressant prescription (odds ratio = 2.29; 95% confidence interval = 2.07, 2.54). Furthermore, selective serotonin reuptake inhibitors (SSRIs) had a significant age-sex interaction. While SSRI prescriptions in men showed a sustained decrease with age, there was no such decline for women until after reaching ∼50 years of age. There are important limitations to consider in this study. Electronic prescription data were cross-sectional; information on treatment duration or adherence was not collected; this cohort is not nationally representative; and enrollment occurred over a broad period, introducing confounding by changes in temporal prescribing practices. Conclusions: Underscored by the significant interaction between age and sex on odds of SSRI prescription, our results warrant age to be incorporated as a mediator when investigating sex differences in mental illness, especially mood disorders and their treatment.

Patterns and factors associated with SSRI medication adherence: a retrospective study using pharmacy claims data

Abstract Objectives To assess the patterns and risk factors associated with selective serotonin reuptake inhibitor (SSRI) medication adherence among enrollees of a multiple employer welfare beneficiary association operating in Florida. Methods This study used a pharmacy claims database for beneficiaries of the Independent Colleges and Universities Benefits Association. The sample of 2541 patients were enrollees who filled two or more consecutive SSRI prescriptions during the analysis period 2015–20. Adherence was measured as the proportion of days covered by a medication. Multiple logistic regression analysis was used to explore the relationship between sociodemographic, healthcare access, and clinical and medication-related factors and adherence. Key findings Adherence was associated with higher odds of being female [odds ratio (OR): 1.2, 95% confidence interval (CI): 0.995–1.464, P &amp;lt; .10] and higher pill burden (OR: 1.3, CI: 1.021–1.642, P&amp;lt; 0.05). Patients using only retail pharmacies (OR: 0.356, CI: 0.196–0.645, P &amp;lt; .01), having any out-of-pocket costs (OR: 0.552, CI: 0.348–0.875, P &amp;lt; .50), changing the prescriber over the duration of the treatment (OR: 0.708, CI: 0.589–0.851, P &amp;lt; .01), taking antihypertensive (OR: 0.708, CI: 0.5077–0.988, P &amp;lt; 0.50), and asthma (OR: 0.609, CI: 0.450–0.826, P &amp;lt; .01) medications were less likely to be adherent. Prescriber specialty was not found to be associated with adherence. Conclusion These findings can inform policymakers and healthcare insurance companies on barriers to medication access and recommend strategies to eliminate these barriers and design interventions to improve the adherence of groups at risk for nonadherence. Healthcare providers can identify patients who are less likely to be adherent and customize counseling interventions for these patients.

Characteristics of patients with anxiety disorder without selective serotonin reuptake inhibitor prescription over a two-year period of pharmacotherapy.

Pharmacotherapy such as selective serotonin reuptake inhibitors (SSRIs) or serotonin-noradrenaline reuptake inhibitors is recommended for the treatment of anxiety disorders. Although there are patients with persisted symptoms of anxiety disorders who are treated with monotherapy of benzodiazepine anxiolytics without SSRIs, the characteristics of these patients are unclear. In the present study, we investigated the characteristics of patients with persisted symptoms of anxiety disorder without SSRI prescription. From a prescription dataset covering 2018 and 2020, the prescriptions of 243 patients with anxiety disorder were analyzed. Patients were classified into two groups: SSRI non-prescription and prescription groups. The SSRI non-prescription group had a higher ratio of females than did the SSRI prescription group (60.1% vs. 44.6%, respectively, p = 3.12 × 10-2 ), but statistically not significant after the Bonferroni correction. No significant differences in age, body mass index, or duration of outpatient visits were found between groups. Among the independent variables, sex (female) was the only variable identified that predicted SSRI non-prescription. The present study showed that among patients with anxiety disorders, sex (female) was the only variable that predicted SSRI non-prescription.

Association of serotonin reuptake inhibitors with asthma control.

Background: Clinical trials demonstrated that selective serotonin reuptake inhibitors (SSRI) can improve asthma control in patients with comorbid major depressive disorder (MDD) and that this effect may be greater than the effect of SSRIs on depression. These findings suggest that SSRIs may improve asthma control in patients without MDD. Objective: The current retrospective study examined the effect of SSRIs and serotonin and norepinephrine reuptake inhibitors (SNRI) on asthma control in adult patients. We hypothesized that patients would have fewer asthma exacerbations after treatment with an SSRI or SNRI. Methods: Electronic health record data of adult patients (N = 592) who were seen at a University of Texas Southwestern (UTSW) hospital or clinic and had (1) an SSRI or SNRI prescription, (2) a previous asthma diagnosis, and (3) no mood disorder diagnosis were extracted by using the UTSW Clinical Data Exchange Network. Wilcoxon signed rank tests were used to compare oral corticosteroid prescriptions and asthma-related emergency department (ED) visits and hospitalizations in the 12 months before and after the start of an SSRI/SNRI. Results: Therapy with SSRIs/SNRIs was associated with a significant decrease in oral corticosteroid use (p = 0.003), ED visits (p = 0.002), and hospitalizations (p < 0.001). Conclusion: Results from the current study add to the existing literature by demonstrating a reduced rate of severe exacerbations in patients with asthma by using an SSRI/SNRI without limiting the analytic sample to a high-illness-severity subgroup defined by symptoms of asthma or depression. Future work should include a prospective, placebo controlled study with individuals who have asthma and no comorbid mental health condition, verified by a mental health professional.

Unsubstantiated use of Selective serotonin reuptake inhibitors as an alternative for the treatment of depression

A Comparison of Pediatric Mental Health Diagnoses and Selective Serotonin Reuptake Inhibitor Prescribing Before and During the COVID-19 Pandemic

PurposeTo assess the rate of mental health diagnoses and selective serotonin reuptake inhibitor (SSRI) prescribing before and during the Coronavirus Disease 2019 pandemic. MethodsWe conducted a cross-sectional study at an ambulatory pediatric clinic. A prepandemic (June 2018 to June 2019) and intrapandemic (June 2020 to June 2021) cohort were reviewed. The rate of mental health visits and new SSRI prescriptions were compared. Chi-squared analyses demonstrated a variance of statistical significance. ResultsFrom 15,414 encounters (9,791 prepandemic and 5,623 intrapandemic), 397 mental health encounters were identified. 231 (4.1%) encounters occurred during the pandemic (vs. 1.7% prepandemic) and 63 (27.3%) SSRIs were prescribed (vs. 5.4% prepandemic). Mental health encounters (prevalence ratio 2.42, 95% confidence interval, 1.99–2.95, p < .001) and SSRI prescriptions (prevalence ratio 5.03, 95% confidence interval, 2.58–9.82, p < .001) were higher during the pandemic. DiscussionOur findings demonstrate increased rates of SSRI prescribing and mental health diagnoses during the Coronavirus Disease 2019 pandemic, suggesting an increased incidence of these conditions. Clinicians should be prepared to manage and screen for mental health conditions.

Abstract 10842: Progression of COVID-19 Severity Among SARS-CoV-2 Positive Patients Prescribed Selective Serotonin Reuptake Inhibitors

Introduction: The clinical spectrum of COVID-19 can range from asymptomatic to severe, with severe resulting in part from an intense inflammatory response. Selective serotonin reuptake inhibitor (SSRI) is the most commonly prescribed class of antidepressants and has anti-inflammatory and anti-platelet effects. Recent studies reported greater survival and lesser COVID severity in patients taking SSRIs, specifically fluoxetine/fluvoxamine. Recently, application was made to the FDA for emergency use of fluvoxamine to prevent severe COVID-19, but it was denied based on insufficient data. Methods: Patients (n=33,088) testing positive for SARS-CoV-2 between March 14, 2020-December 31, 2021 as outpatients were studied. Patients were matched 3:1 by SSRI prescription at the time of a positive test by propensity score (±0.001). Patients were evaluated for COVID-19 hospitalization within 14-days and death within 3-months of positive SARS-CoV-2 test. Results: A total of 8,272 SSRI patients were well-matched to 24,816 no SSRI patients (Table 1). Hospitalization and death were significantly greater in the SSRI group compared to the no SSRI group (Table 1). A total of 2,067 (25.0%) of SSRI patients were taking fluoxetine or fluvoxamine. While attenuated, no SSRI remained associated with a lower 14-day COVID-19 hospitalization risk when compared to fluoxetine or fluvoxamine use, but not with 3-month death (Table 2). Conclusion: This study did not find a lower risk of progression of COVID-19 severity with the use of any SSRI or fluoxetine/fluvoxamine alone. Results from this study support the FDA’s decision to not recommend their use at an early stage of a COVID-19 infection.

New prescription fills of selective serotonin reuptake inhibitors before and during the COVID-19 pandemic in Los Angeles County, California

ObjectiveThis study examined whether the COVID-19 pandemic was associated with changes in new selective serotonin reuptake inhibitor (SSRI) prescription fills. MethodsUsing IQVIA Xponent data on new SSRI fills in Los Angeles (L.A.) County from March 2019 to June 2021, the authors implemented an interrupted time series analysis comparing the monthly volume and trend of overall fills and fills by age and gender from before to after the pandemic declaration. ResultsThe rate of new SSRI prescription fills briefly decreased after the pandemic declaration but then consistently increased through the rest of the study period. These increases were primarily driven by women, young adults (i.e., 18–39 year-olds), and those under 18 years old. LimitationsSample is limited to one county and may not be generalizable to other municipalities. ConclusionsThe COVID-19 pandemic was associated with significant increases in new SSRI fills among women, young adults, and those under 18. These increases were relatively small compared to increases in depressive symptoms during the same time period.

Association between CYP metabolizer phenotypes and selective serotonin reuptake inhibitors induced weight gain: a retrospective cohort study

BackgroundPrescription medications such as selective serotonin reuptake inhibitors (SSRIs), commonly used to treat depression, are associated with weight gain. The role of pharmacogenomics in predicting SSRI-induced weight gain is unclear.MethodsIn this retrospective cohort study from participants in the Mayo Clinic RIGHT study who were prescribed citalopram, paroxetine, sertraline, or fluoxetine, our aim was to evaluate the association of metabolizer phenotype and total body weight after 6 months of SSRIs initiation. We evaluated the metabolizer phenotypes (poor/intermediate, normal, and rapid/ultra-rapid) of the cytochromes P450 enzymes genes: CYP2C9, CYP2C19, and CYP2D6 known to influence the metabolism of SSRI medications: CYP2C19 for citalopram, CYP2D6 for paroxetine, CYP2D6 and CYP2C19 for sertraline, and CYP2D6 and CYP2C9 fluoxetine. In addition, we assessed the association of metabolizer phenotype and total body weight change at six months following SSRI prescription using parametric analysis of covariance adjusted for baseline body weight and multivariate regression models.ResultsCYP2C19 poor/intermediate metabolizers prescribed citalopram gained significantly more weight than normal or rapid/ultra-rapid metabolizers at 6 months (TBWG %: 2.6 [95% CI 1.3—4.1] vs. 0.4 [95% CI -0.5 – 1.3] vs. -0.1 [-95% CI -1.5—1.1]; p = 0.001). No significant differences in weight outcomes at six months of treatment with paroxetine, sertraline, or fluoxetine were observed by metabolizer status.ConclusionsWeight gain observed with citalopram may be mediated by CYP2C19 metabolizer status.

Serious arrhythmia in initiators of citalopram, escitalopram, and other selective serotonin reuptake inhibitors: A population-based cohort study in older adults.

The selective serotonin reuptake inhibitors (SSRIs) citalopram and escitalopram are associated with QT prolongation, which increases the risk of serious arrhythmia. Consequently, regulatory agencies issued safety warnings in 2011. This study aimed to investigate the risk of serious arrhythmia following initiation of citalopram or escitalopram compared to other SSRIs and the risk in the periods before and after the warnings were issued. We conducted a series of nationwide cohort studies emulating a target trial using Danish healthcare register data from January 1, 2002, to December 31, 2016. We included patients (aged ≥65 years) who filled an SSRI prescription with a 1‐year washout period before the index date. The outcome was an event of serious arrhythmia. Individuals were followed for a maximum of 6 months using an intention‐to‐treat approach. Log‐binomial regression analyses were performed, estimating risk ratios (RRs) and 95% confidence intervals (CIs) adjusting for age and sex, comorbidities, and comedications with propensity scores. Dose–response effects were not investigated because dosage instructions were not available. We included 167,366 (146,014 individuals), 40,113 (37,069 individuals), and 50,281 (44,754 individuals) person‐trials of citalopram, escitalopram, and other SSRIs, respectively. In total, there were 228 events of serious arrhythmia. No difference in risk was observed in the entire study period for either citalopram (0.87 [0.62–1.22]) or escitalopram (0.85 [0.53–1.40]). We identified lower point estimates after the safety warning, RR 0.54 (95% CI 0.31–0.93) for citalopram and 0.58 (0.20–1.63) for escitalopram. Initiation of citalopram and escitalopram was not associated with an increased risk of serious arrhythmia. However, lower point estimates were observed after the safety warning.

Association of selective serotonin re-uptake inhibitor (SSRI) treatment with acute substance misuse outcomes.

Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed medications for patients with anxiety/depression. These patients often have problems with substance use, but it remains unclear whether the risk of substance misuse is influenced by SSRI treatment. We aimed to determine whether SSRI treatment is associated with a decreased risk of acute substance misuse-related outcomes. Cohort study following individuals through Swedish nation-wide registers between July 2005 and December 2013 and comparing the risk of substance misuse outcomes during periods on- versus off-treatment within the same individual. Swedish general population. Individuals with a newly dispensed prescription of SSRIs between July 2006 and December 2013 and an ICD-10 diagnosis of anxiety/depressive disorder before the first treatment initiation. The cohort included 146 114 individuals (60.7% women). Substance misuse outcomes included ICD-10 diagnoses of acute intoxications (F10.0-F19.0), accidental poisonings by alcohol or drugs (X41-X42, X45-X46) and substance-related criminal offenses. The absolute rate of substance misuse increased sharply before the onset of SSRI treatment and decreased after treatment initiation. Stratified Cox regression models showed an elevated risk [hazard ratio (HR)=1.70, 95% confidence interval (CI)=1.62-1.78] of substance misuse outcomes during a 1-month period preceding treatment initiation, compared with the reference period of more than 1month before treatment start. The on-treatment estimates (1-30days, HR=1.29, 95% CI=1.23-1.37; 31-120days, HR=1.30, 95% CI=1.24-1.35; and >120days, HR=1.24, 95% CI=1.18-1.30 after treatment initiation] were consistently lower than the 1-month pre-treatment estimate, but still elevated compared with the reference period. For people with anxiety/depression, the risk of substance misuse appears to be particularly elevated immediately before initiating selective serotonin reuptake inhibitor (SSRI) treatment, which may reflect the emergence or worsening of substance use problems concurrently with anxiety/depression. SSRI treatment appears to be associated with a lower risk of substance misuse compared with the 1-month period preceding treatment initiation, but causality remains uncertain.

Impact of Antidepressant Prescriptions on Suicidal Behavior in Times of Severe Financial Strain.

This descriptive study observes the relationship between antidepressant prescriptions and the suicide rate in Italy in the 2000s to the mid-2010s, which includes a period of severe economic crisis. The observation period was from 2000 to 2015. Suicide and unemployment rates disaggregated by age and sex were collected from the Italian Institute of Statistics. Statistical analyses were performed using correlations between suicide rates and the defined daily dose, with reference to selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), and other types of antidepressants. Fixed-effects panel regressions were also run. Increases in SSRIs prescriptions were associated with decreases in suicide rates among both men and women. However, when the analyses were adjusted for the rate of growth of the unemployment rate and for gross domestic product, the associations were weaker. The potential protective factor of SSRIs with respect to suicidal behavior may be reduced by severe recessions, especially when unemployment increases.

Association of Selective Serotonin Reuptake Inhibitors With the Risk of Type 2 Diabetes in Children and Adolescents

Concerns exist that use of selective serotonin reuptake inhibitors (SSRIs) increases the risk of developing type 2 diabetes (T2D) in adults, but evidence in children and adolescents is limited. In the absence of a randomized clinical trial, evidence must be generated using real-world data. To evaluate the safety of SSRI use in children and adolescents with respect to the associated risk of T2D. This cohort study of patients aged 10 to 19 years with a diagnosis for an SSRI treatment indication was conducted within the nationwide Medicaid Analytic eXtract (MAX; January 1, 2000, to December 31, 2014) and the IBM MarketScan (January 1, 2003, to September 30, 2015) databases. Data were analyzed from November 1, 2018, to December 6, 2019. New users of an SSRI medication and comparator groups with no known metabolic adverse effects (no antidepressant exposure, bupropion hydrochloride exposure, or psychotherapy exposure). Within-class individual SSRI medications were compared with fluoxetine hydrochloride. Incident T2D during follow-up. Intention-to-treat effects were estimated using Cox proportional hazards regression models, adjusting for confounding through propensity score stratification. As-treated effects to account for continuous treatment were estimated using inverse probability weighting and marginal structural models. A total of 1 582 914 patients were included in the analysis (58.3% female; mean [SD] age, 15.1 [2.3] years). The SSRI-treated group included 316 178 patients in the MAX database (publicly insured; mean [SD] age, 14.7 [2.1] years; 62.2% female) and 211 460 in the MarketScan database (privately insured; mean [SD] age, 15.8 [2.3] years; 63.9% female) with at least 2 SSRI prescriptions filled, followed up for a mean (SD) of 2.3 (2.0) and 2.2 (1.9) years, respectively. In publicly insured patients, initiation of SSRI treatment was associated with a 13% increased hazard of T2DM (intention-to-treat adjusted hazard ratio [aHR], 1.13; 95% CI, 1.04-1.22) compared with untreated patients. The association strengthened for continuous SSRI treatment (as-treated aHR, 1.33; 95% CI, 1.21-1.47), corresponding to 6.6 (95% CI, 4.2-10.4) additional cases of T2D per 10 000 patients treated for at least 2 years. Adjusted HRs were lower in privately insured patients (intention-to-treat aHR, 1.01 [95% CI, 0.84-1.23]; as-treated aHR, 1.10 [95% CI, 0.88-1.36]). Findings were similar when comparing SSRI treatment with psychotherapy (publicly insured as-treated aHR, 1.44 [95% CI, 1.25-1.65]; privately insured as-treated aHR, 1.21 [95% CI, 0.93-1.57]), whereas no increased risk was observed compared with bupropion treatment publicly insured as-treated aHR, 1.01 [95% CI, 0.79-1.29]; privately insured as-treated aHR, 0.87 [95% CI, 0.44-1.70]). For the within-class analysis, no medication had an increased hazard of T2D compared with fluoxetine. These findings suggest that children and adolescents initiating SSRI treatment may be at a small increased risk of developing T2D, particularly publicly insured patients. The magnitude of association was more modest than previously reported, and the absolute risk was small. The potential small risk should be viewed in relation to the efficacy of SSRIs for its major indications in young patients.

Bridging the mental health treatment gap: effects of a collaborative care intervention (matrix support) in the detection and treatment of mental disorders in a Brazilian city.

ObjectiveTo analyse temporal trends in diagnosis and treatment of mental disorders in primary care following implementation of a collaborative care intervention (matrix support).DesignDynamic cohort design with retrospective time-series analysis. Structured secondary data on medical visits to general practitioners of all study clinics were extracted from the municipal electronic records database. Annual changes in the odds of mental disorders diagnoses and antidepressants prescriptions were estimated by multiple logistic regression at visit and patient-year levels with diagnoses or prescriptions as outcomes. Annual changes during two distinct stages of the intervention (stage 1 when it was restricted to mental health (2005–2009), and stage 2 when it was expanded to other areas (2010–2015)) were compared by adding year–period interaction terms to each model.Setting49 primary care clinics in the city of Florianópolis, Brazil.ParticipantsAll adults attending primary care clinics of the study setting between 2005 and 2015.Results3 131 983 visits representing 322 100 patients were analysed. At visit level, the odds of mental disorder diagnosis increased by 13% per year during stage 1 (OR 1.13, 95% CI 1.11 to 1.14, p<0.001) and decreased by 5% thereafter (OR 0.95, 95% CI 0.94 to 0.95, p<0.001). The odds of incident mental disorder diagnoses decreased by 1% per year during stage 1 (OR 0.99, 95% CI 0.98 to 1.00, p=0.012) and decreased by 7% per year during stage 2 (OR 0.93, 95% CI 0.92 to 0.93, p<0.001). The odds of antidepressant prescriptions in patients with a mental disorder diagnosis increased by 7% per year during stage 1 (OR 1.07, 95% CI 1.05 to 1.20, p<0.001); this was driven by selective serotonin reuptake inhibitor prescriptions which increased 14% per year during stage 1 (OR 1.14, 95% CI 1.12 to 1.18, p<0.001) and 9% during stage 2 (OR 1.09, 95% CI 1.08 to 1.10, p<0.001). The odds of incident antidepressant prescriptions did not increase during stage 1 (OR 1.00, 95% CI 0.97 to 1.02, p=0.665) and increased by 3% during stage 2 (OR 1.03, 95% CI 1.00 to 1.04, p<0.001). Changes per year were all significantly greater during stage 1 than stage 2 (p values for interaction terms <0.05), except for antidepressant prescriptions during visits (p=0.172).ConclusionThe matrix support intervention may increase diagnosis and treatment of mental disorders when inter-professional collaboration is adequately supported. Competing demands to the primary care teams can subsequently reduce these effects. Future studies should assess clinical outcomes and identify active components and factors associated with successful implementation.

Diplopia; an Adverse Effect of Citalopram

Citalopram, a selective serotonin reuptake inhibitor (SSRI), was approved by the Food and Drug Administration in 1998 as a safe and well-tolerated antidepressant; the use of it may result in rare and sometimes dangerous side effects. Diplopia is a rare adverse effect of citalopram that comes with double vision and disrupts daily living. Currently, only two cases of citalopram-related diplopia have been internationally reported. The current paper presents a third reported case of diplopia following citalopram use in a healthy subject. A 47-year-old man involved in an accident was subsequently affected by serious depression. Following 6 months of a 40-mg daily dose of citalopram, the patient complained of itchy irritated eyes and double vision symptomatic of diplopia. He was referred to an eye specialist, who confirmed no apparent problems following an examination of the eye. After a decrease in the dose of citalopram, the eye symptoms steadily decreased and eventually disappeared. The rapid disappearance of diplopia subsequent to the discontinuing use of citalopram suggests an association between the adverse reaction and the medicine. As a result, it is recommended that physicians inform patients of the possibility of induction of diplopia related to the use of citalopram and other SSRIs. In the future, the prescription of SSRIs at higher doses may be ordered with and on the recommendation of patients, who have been aware of the risks of the drug.

Clinician compliance to recommendations regarding the risk of suicidality with selective serotonin reuptake inhibitors in the treatment of children and adolescents

Meta-analyses of randomized-controlled trials have established a heightened risk of suicidality for children and adolescents treated with selective serotonin reuptake inhibitors (SSRIs). The present study examined to what extent daily clinical practice complied with specific recommendations regarding the risk of suicidality when treating children and adolescents with SSRIs. All in- and outpatients aged 0–17 years at the Child and Adolescent Mental Health Services, Capital Region of Denmark with a prescription for SSRI on January 1st, 2016 were identified. Data were obtained for n = 365 patients regarding the level of clinician compliance to deliver pre-consent information about adverse effects, monitor for suicidality, and provide non-pharmacological interventions. 81.7% (n = 298) of patients received pre-consent information about adverse effects. 67.7% (n = 247) were monitored for suicidality within 6 weeks after SSRI initiation. Children (0–13 years) were less likely to be monitored for suicidality compared to adolescents (14–17 years) (49.6% vs. 77.5%, p < 0.001). Patients with depression as indication for SSRI treatment were more likely to be monitored for suicidality than patients with other indications (OR = 3.4, p = 0,002) and more likely to receive information specifically about suicidality (34.7% vs. 19.7%, p = 0.002). Respectively, 89.3% (n = 326) and 93.4% (n = 341) of all SSRI-treated patients were treated with non-pharmacological interventions prior to and in parallel with SSRI treatment. For the majority of cases, treatment of children and adolescents with SSRI complied with recommendations from clinical guidelines. However, patients of younger age and/or with indications for SSRIs other than depression were less likely to be managed according to recommendations.

Selective serotonin reuptake inhibitors use in pregnancy: a risk assessment study using administrative pharmaceutical data

BackgroundAntidepressant management with Selective Serotonin Reuptake Inhibitors (SSRI) during pregnancy is associated with risks of congenital malformations and adverse pregnancy outcomes.&#x0D; Main AimWe examined the incidence of SSRI use during pregnancy using Australian administrative pharmaceutical data linked to medical service data detailing antenatal consultations to assess pregnancy risk at current levels of treatment.&#x0D; MethodA published data source from the Australian Pharmaceutical and Medical Benefit Schemes was used to identify pregnant women starting new onset treatments with SSRI medications during the provision of antenatal services. A longitudinal profile of SSRI incidence in the pre, peri and post pregnancy periods were constructed to define incident SSRI use. The potential increased burden from adverse pregnancy outcomes was calculated using estimates of risks from the literature.&#x0D; ResultsFrom 2005-2011, 40,778 women were identified to have started de novo SSRI treatments within 10 years of pregnancy (n=172,951). The prenatal monthly incidence of SSRI prescriptions was 25 per 1000 women in 2005 and 7.5/1000 in 2011. During pregnancy, this incidence fell to 7.5 and 4/1000 women in years, and rose above perinatal levels to between 13 and 33/1000 women one year postnatally (X2 p&lt;.001). At these incidence rates, an estimated 2400 women per year receive SSRI’s during pregnancy. In comparison, with non-depressed pregnant women this potentially results in 10 further cardiovascular defects, 94 pre-term births, and 1 still birth annually.&#x0D; ConclusionThis pharmaco-surveillance study has demonstrated continued use of SSRIs in Australian women of childbearing age but diminishing usage during pregnancy. A small number of women continue to be prescribed SSRI during the prenatal period in Australia with risks of adverse pregnancy outcomes.
