Moving beyond first-line treatment options for OCD.

OCD is characterized by obsessions and compulsions that cause distress, are time-consuming, and interfere with a patient's social, occupational, or other areas of functioning. SSRIs are first-line pharmacologic treatment options and produce response rates of up to 60% in patients with OCD. Several potential strategies have been evaluated for enhancing patient response, including high-dose SSRI therapy, antipsychotic augmentation, and memantine augmentation. Three patient cases are used to explore treatment guidelines, evaluate existing literature, and provide pharmacotherapy recommendations for the management of patients with OCD when first-line therapy fails.

Addressing clozapine under-prescribing and barriers to initiation: a psychiatrist, advanced practice provider, and trainee survey.

Clozapine use has declined, despite its superior antipsychotic efficacy in treatment-resistant schizophrenia. Implications for clozapine underutilization include suboptimal treatment outcomes and increased hospitalizations. Many barriers preventing the use of clozapine have been described in the literature, including suboptimal knowledge and poor perceptions. The aim of this study was to assess psychiatry prescribers' perception and knowledge of clozapine. A survey was distributed to advanced practice providers, psychiatrists, and trainees (i.e. residents and fellows) at 10 medical centers within the US and Canada. The survey asked respondents about their perception of clozapine use and assessed their pharmacotherapeutic knowledge of clozapine. Two hundred eleven individual submitted completed surveys of a possible 1152; a response rate of 18.3%. There were no statistically significant differences between the advanced practice provider plus psychiatrist groups and the trainee group for most perception (eight of nine) and knowledge (eight of nine) questions. The knowledge questions with the lowest scores pertained to clozapine reinitiation and myocarditis. The majority of all respondents (144, 68.2%) felt that clozapine prescribing was a burden. Findings of this study support the need for continued clozapine education regardless of a prescriber's age/experience. Future studies to assess barriers to clozapine prescribing should extend beyond academic centers.

Prevalence and Predictors of Benzodiazepine Monotherapy in Patients With Depression: A National Cross-Sectional Study.

OBJECTIVE: Depression guidelines discourage benzodiazepine monotherapy and limit use to short-term adjunctive therapy with antidepressants; however, patients with depression continue to receive benzodiazepine monotherapy. The prevalence and predictors of this prescribing pattern have not been described previously and are warranted to assist clinicians in identifying patients at highest risk of receiving benzodiazepine monotherapy. METHODS: A national, cross-sectional analysis of the National Ambulatory Medical Care Survey from 2012 to 2015 was performed for adults treated for depression. Depression was identified using a survey item specifically assessing the presence of depression. Office visits involving patients with bipolar disorder, schizoaffective disorder, or pregnancy were identified by ICD-9 code or specific survey item and were excluded. The primary endpoint was benzodiazepine monotherapy prescribing rate defined as initiation or continuation of a benzodiazepine in the absence of any antidepressant agent. A multivariate logistic regression model was created to identify variables associated with benzodiazepine monotherapy. RESULTS: In total, 9,426 unweighted visits were eligible for inclusion. Benzodiazepine monotherapy was identified in 9.3% of patients treated for depression (95% CI, 8.2%-10.6%). Predictors of benzodiazepine monotherapy included age of 45-64 years (OR = 1.39; 95% CI, 1.01-1.91), epilepsy-related office visit (OR = 5.34; 95% CI, 1.39-20.44), anxiety-related office visit (OR = 1.67; 95% CI, 1.23-2.27), underlying pulmonary disease (OR = 1.43; 95% CI, 1.09-1.87), and concomitant opiate prescribing (OR = 2.86; 95% CI, 2.01-4.06). Psychiatrists were less likely to prescribe benzodiazepine monotherapy than were other providers (OR = 0.42; 95% CI, 0.29-0.61). CONCLUSIONS: Benzodiazepine monotherapy is utilized in nearly 1 in 10 patients treated for depression. Adults aged 45 to 65 years, patients prescribed opioids, patients seen by primary care providers, and those with underlying anxiety, epilepsy, or pulmonary disorders are at highest risk.

Evaluation of dextromethorphan with select antidepressant therapy for the treatment of depression in the acute care psychiatric setting.

INTRODUCTION: Dextromethorphan (DXM), an N-methyl-D-aspartate receptor antagonist, may have ketamine-like antidepressant effects. Dextromethorphan is extensively metabolized via cytochrome P450 (CYP) 2D6, and its half-life in extensive metabolizers is 2 to 4 hours. The purpose of this study was to evaluate the effects of DXM in combination with a moderate-to-strong CYP2D6 inhibitor antidepressant on depression in an acute care psychiatric setting. METHODS: This was a single-center, retrospective chart review of adult patients with a depressive disorder diagnosis. Patients who received select antidepressant therapy with or without scheduled DXM were included. The primary outcome was the difference in time to improvement of depressive symptoms, which was an average composite of physician documentation, nurse documentation, and first time to 24 hours without as-needed anxiolytics or antipsychotics. The study group consisted of patients who received DXM with select antidepressant therapy, whereas the control group included those who received only select antidepressant therapy. RESULTS: A total of 40 patients were included. The median time to clinical improvement was 3.00 days and 2.83 days for the study group and control group, respectively (P = .986). The incidence of perceptual disturbances and delusions was higher in the study group as compared with the control group (55% and 35% vs 30% and 25%, respectively). DISCUSSION: Dextromethorphan was not associated with a rapid antidepressant effect. The commonly used dose of 30 mg daily may have been too low to have an effect; additionally, the most frequently utilized select antidepressant, bupropion, has moderately less CYP2D6 inhibition than fluoxetine and paroxetine.

Evaluation of oral antipsychotic supplementation of select second-generation long-acting injectable antipsychotics in an acute-care psychiatric setting.

INTRODUCTION: Long-acting injectable (LAI) antipsychotics were developed to increase medication adherence in patients with schizophrenia. The US Food and Drug Administration (FDA)-approved LAI dosing provides guidance regarding oral antipsychotic supplementation. Previous studies have concluded concomitant use of oral and LAI antipsychotics requires further investigation. The aim of this study was to examine oral antipsychotic supplementation among patients receiving select second-generation LAIs. METHODS: Patients were included if they were admitted to an inpatient psychiatric unit and received a second-generation LAI. The primary outcome was to determine the percentage of patients receiving oral antipsychotic supplementation prescribed in accordance with FDA recommendations. Secondary outcomes described oral supplementation prescribed in an inconsistent manner with FDA recommendations and identified patient-specific predictors associated with oral supplementation prescribed consistent with FDA recommendations. RESULTS: Of the 422 patients evaluated, 376 patients met inclusion criteria. Oral supplementation was prescribed in a manner consistent with FDA recommendations in 30% of patients. The following predictors were associated with oral supplementation prescribed in accordance with FDA recommendations: LAI initiation (odds ratio 1.868, 95% confidence interval 1.120-3.125) and the use of the once-monthly paliperidone LAI (odds ratio 20.278, 95% confidence interval 10.472-39.873). DISCUSSION: In the patient population evaluated, oral supplementation of LAI antipsychotics were prescribed in 30% of patients in a manner consistent with FDA recommendations. Of the patients who were prescribed oral antipsychotic supplementation inconsistent with FDA labeling, 223 patients were prescribed oral supplementation longer than the recommended duration and 8 patients received oral supplementation for a shorter duration than recommended.
