Practical considerations for estimating clinical trial accrual periods: application to a multi-center effectiveness study
BACKGROUND Adequate participant recruitment is vital to the conduct of a clinical trial. Projected recruitment rates are often over-estimated, and the time to recruit the target population (accrual period) is often under-estimated. METHODS This report illustrates three approaches to estimating the accrual period and applies the methods to a multi-center, randomized, placebo controlled trial u...
متن کاملClinical Trial Accrual: Obstacles and Opportunities

متن کاملPractical considerations in the clinical application of whole-exome sequencing.
Despite the exciting advent of whole-exome sequencing (WES) in medical genetics practices, the optimal interpretation of results requires further actions such as reconsidering clinical information and obtaining further laboratory testing. There are no published data to guide clinicians in this process. In a retrospective study on 93 patients who underwent clinical WES, we set out to assess and ...
متن کاملAnalysis of Speech Movements: Practical Considerations and Clinical Application
The instrumental evaluation of speech movements is an important adjunct to the assessment and understanding of speech motor disorders. AIl the interface between the nervous system and aerodynamic modifications in the vocal tract, movement variables such as displacement, velocity, acceleration, and their time histories, can provide direct information on speech motor disorders that can only be in...
متن کاملComplications in Using Automated Methods to Increase Clinical Trial Accrual
Purpose: This paper reports on the issues involved in improving accruals for cancer-related clinical trials. Clinical trials aim to determine the efficacy of novel therapies and must be conducted before new medical treatments become available to the public. In order for the clinical trial to be successful, a predetermined number of patients with an appropriate set of medical conditions must be ...
