Claustrophobia and disruptive patient motion are common impediments to MRI examination, but they may be prevented or ameliorated with a non-pharmacologic behavioral intervention administered by trained staff. The potential benefits of such an intervention are highly significant, considering that the alternatives are to cancel the study or administer sedation. Inability to complete their MRI scans adversely affects an estimated 700,000 patients every year in the US. These patients are either deprived of a diagnosis, subject to diagnostic delays, or are exposed to risks of pharmacologic sedation, including death. The imaging facilities in turn, typically cannot fill the suddenly vacated examination slots in time before the next scheduled patient and thus incur considerable lost revenue and efficiency. The long-term goal is to provide a validated, clinically feasible means for non-pharmacologic amelioration of claustrophobia and disruptive patient motion, achieved by training MRI staff to use advanced rapport skills and comforting language to help patients. Phase I will design and perform a formative evaluation of a Comfort Talk® Training intervention so that definitive testing of the hypothesized benefits for the intervention can be accomplished in Phase II.
