Objective: The purpose of this study was to discern radiologists' perceptions regarding the implementation of a decision support system intervention as part of the Medicare Imaging Demonstration project and the effect of decision support on radiologists' interactions with ordering clinicians, their radiology work flow, and appropriateness of advanced imaging.
Subjects And Methods: A focus group study was conducted with a diverse sample of radiologists involved in interpreting advanced imaging studies at Medicare Imaging Demonstration project sites. A semistructured moderator guide was used, and all focus group discussions were recorded and transcribed verbatim.
Sol-gel derived tetraethylorthosilicate (TEOS) films were prepared by spin coating method on indium tin oxide (ITO) coated glass plate. Hydrophobic interaction method was used to coat the bovine serum albumin film over the surface of tetraethylorthosilicate sol-gel film to minimize cracking, biofouling and to improve the stability of the film. Cholesterol oxidase (ChOx) and horseradish peroxidase (HRP) were immobilized using covalent linkage with bovine albumin serum film to enhance the loading of the enzyme to improve the sensitivity of biosensor.
