Nonpharmacologic Reduction of Periprocedural Distress and Drug Use

Objectives of this Phase I pilot trial are to provide data towards assessing and facilitating feasibility of a larger scale Phase II trial in which the effects of a calmative Comfort Talk® app can be unequivocally evaluated. Towards this goal we will pursue following outcome parameters for Phase I: Feasibility/acceptability assessment: Primary outcome parameter: • ability to obtain complete on-site data sets from at least 90% of patients enrolled (with at least 40% from patients in the app group and at least 40% from patients in the control group). Secondary outcome parameters: * ability to enroll 60 patients by day 150 after initiation of recruitment in the clinic (=day 1) * obtain 38 packages of filled out diary cards (at least 16 from patients in the app group and at least 16 from patients in the control group) * 90% of patients in app group listen to app ≥5 min Phase II preparation primary outcome parameter • anxiety at the end of the waiting room time Secondary outcome parameters * pain the end of the waiting room time * anxiety during treatment * pain during treatment * anxiety during 1 week after treatment * pain during 1 week after treatment * use of units of sedatives and analgesics during 1 week after treatment (assessed by prescription at end of the visit) * patient satisfaction
