All participants reported that they were comfortable using the video decision aid, that they would recommend it to others, and that it clarified POLST decisions. CONCLUSIONS Participants endorsed the use of a POLST video decision aid, which increased their knowledge of POLST form options and satisfaction with their decisions, and decreased their decisional conflict in POLST completion. This pilot study provides preliminary support for the use of video decision aids for POLST decision-making. Future research should evaluate a decision aid for the entire POLST form and identify patient preferences for implementing POLST decision aids into clinical practice.BACKGROUND Peripheral intravenous catheter placement is frequently unsuccessful at the first attempt. One suggested risk factor is a small vein size, because of the consequences of mechanical forces generated by the needle tip. We developed short bevel needles with a very thin tip and evaluated their puncture performance in two in vitro models. METHODS Peripheral intravenous catheters with a new needle ground using the lancet method (experimental catheter (L)) or backcut method (experimental catheter (B)) were compared with a conventional peripheral intravenous catheter (Surshield Surflo®) in a penetration force test and a tube puncture test. Penetration forces were measured when peripheral intravenous catheters penetrated a polyethylene sheet. The tube puncture test was used to evaluate whether the peripheral intravenous catheters could puncture a polyvinyl chloride tube at two positions, at the center and at 0.5 mm from the center of the tube. RESULTS Mean penetration forces at the needle tip produced by exnt, which may increase the first-attempt success rate.BACKGROUND Many studies suggested that the optimal cephalic vein diameter for
