Stroke Clinical Trial - Post-stroke Triage "DOC": Simple Screening for

Status Completed

Clinical Trial Summary

The purpose of this study is to determine whether simple, evidence-based clinical screening be quickly and feasibly implemented (>85% of patients in an average of <6 minutes) in large-volume urgent transient ischemic attack (TIA)/stroke clinics to identify individuals at high risk for the three most common and devastating post-stroke co-morbidities (depression, obstructive sleep apnea and cognitive disorders).

Clinical Trial Description

We have created a simple screening tool (the "DOC" Screen) that will be routinely applied to all patients at a high-volume Regional Stroke Prevention Clinic. Consenting patients will also undergo "gold standard" research assessments in order to determine the diagnostic characteristics of the screen compared to gold standard research assessments.The proportion of eligible patients who complete DOC screening and the time for completion (mean, range, standard deviations) will be calculated from aggregated data for all new consults in the stroke prevention clinic. For patients who consented to undergo gold standard testing, sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios of the DOC screen will be calculated. Screening cut-points will be optimized using Receiver Operating Characteristic (ROC) and area under the curve analysis, and logistic regression will be applied to this ROC Curve analysis to control for variables such as age, sex, BMI and education. We hope to develop a pragmatic approach to screening the large, high-risk stroke prevention clinic population, allowing broad screening for these important health conditions. This could change routine standard of care across stroke prevention clinics and facilitate early identification and appropriate assessment of patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
