Filter by:Our proposed evaluation study is designed to evaluate the impact of a recently completed stepped wedge cluster randomized trial, conducted at Kaiser Permanente Washington (KPWA), of an intervention to improve care and management of patients with drug use disorders (DUDs) in primary care (Aim 1). We will also explore the reasons for any apparent gaps in DUD care by analyzing clinicians' free-text encounter notes using manual chart review, natural language processing (NLP), and/or NLP-assisted manual chart review, as appropriate (Aim 2). Specific Project Aims are as follows: Aim 1 The primary research question we address in Aim 1 is whether routine screening for drug use disorders in primary care (PC) settings increases DUD treatment. We define DUDs as including opioid use disorders (OUD), cannabis use disorders (CUD), and other non-alcohol drug use disorders (OTH). Previously published analyses indicate that the 22 PC clinics in this trial sustained very high rates of screening (88%) and a 3-clinic DUD pilot study suggested that this screening resulted in increased diagnosis of CUD and increased treatment of DUDs in general, even at relatively low observed rates of PC-based screening and assessment. Aim 2 The overall goal of Aim 2 is to expand our understanding of gaps in DUD diagnosis and treatment that persist-despite implementation of high rates of PC screening and assessment for SUDs-using rich information available only in free-text chart notes. Through analysis of relevant chart notes Aim 2 of this project will descriptively characterize gaps in DUD diagnosis and DUD treatment (i.e., instances where information in a patient's record suggests a DUD could be diagnosed but no diagnosis is present, or a new diagnosis suggest treatment is indicated but no evidence of treatment is present), and characterize reasons for DUD care gaps.
This research project proposes a novel approach to elucidate the biological adaptations associated with heavy cannabis use and to assess whether such adaptations are predictive of higher cannabis craving in response to both cannabis cues and stressors.
The purpose of this proof-of-concept study is to evaluate the safety, feasibility and acceptability of a breathwork workshop intervention in individuals with cannabis use disorder.
General objective: To assess the effectiveness of a treatment program specific for cannabis abuse (cognitive behavioral treatment + pharmacological treatment) compared to standard treatment (pharmacological treatment + psychoeducation) in patients with first episodes psychosis (FEP) cannabis users. Design A multicenter single-blind randomized study with 1 year of follow-up. The effectiveness of a treatment program specific for cannabis abuse (cognitive behavioral treatment + pharmacological treatment) compared to standard treatment (pharmacological treatment + psychoeducation) in patients with first episodes psychosis (FEP) cannabis users will be assessed. Patients will be randomly assigned to one of two treatments: 1. Experimental group (N=50): Cognitive-behavioral treatment specific for cannabis abuse + pharmacological treatment 2. Control group (N=50): standard treatment: psychoeducation + pharmacological treatment
This project tests the feasibility and utility of a novel, integrated approach to treatment of patients with cannabis use disorder (CUD) and anxiety disorders.
The goal of this project is to test the effectiveness of a computer-facilitated alcohol screening and brief intervention (c-ASBI) system for 12- to 18-year-old primary care patients in a multi-site, randomized comparative effectiveness trial. The investigators hypothesize that, among 12- to 18-year olds patients coming for annual well-care, those receiving c-ASBI will have lower rates of any alcohol use at 3-, 6-, and 12-month follow-ups compared to Treatment As Usual (TAU).
Many individuals with schizophrenia also suffer from marijuana addiction that worsens their problems related to schizophrenia. Most of the medications prescribed for schizophrenia have no effect on reducing marijuana use. Preliminary data suggests that clozapine, an atypical antipsychotic, may limit marijuana use in people diagnosed with schizophrenia, but it is not commonly used due to its side effects and is reserved for people who do not respond to other antipsychotic medications. In the proposed study, 132 individuals who are diagnosed with both schizophrenia and a cannabis use disorder will be randomized to a 12-week treatment course with either clozapine or risperidone (another commonly prescribed antipsychotic medication) to test the hypothesis that patient treated with clozapine will have decreased cannabis use as compared to patients treated with risperidone. Should this study indicate that clozapine will lessen marijuana use in persons diagnosed with schizophrenia more than risperidone, it will provide evidence needed to begin to shift clinical practice toward its use in this population.
Background: - Marijuana is the most widely used illicit drug in the world, yet relatively little is known about users who try to quit without formal treatment ( spontaneous quitting). Studies have suggested that there are some common strategies that many individuals use in spontaneous quitting, such as changing one s lifestyle or identity, reminding oneself of negative consequences, support from family and friends, and religion. However, more research is needed to determine potential treatment strategies for marijuana use. Objectives: - To identify strategies used to help with marijuana quitting among non-treatment seeking adult marijuana users. - To identify withdrawal symptoms experienced during marijuana quitting and their relationship to the quitting strategies used and the outcome of the quit attempt. - To evaluate whether subgroups of marijuana users differ in their experience of marijuana quitting. Eligibility: - Individuals at least 18 years of age who have made at least one attempt to quit marijuana use. Design: - The study will consist of one visit of approximately 1 to 2 hours. - Participants will fill out three questionnaires. The questionnaires have different types of questions, and will ask about background and lifestyle, marijuana use and craving patterns and behaviors, and difficulties in previous attempts to quit using marijuana.
The primary purpose is to assess the efficacy in human of N-acetylcysteine versus placebo during 4 weeks in cannabis withdrawal.
The primary objective of this application is to test the neurobehavioral mechanisms and effects of aprepitant as a new cessation agent for cannabis, tobacco or both.
