Health Information Technology and Management Richard Gartee Pretest (True/False) During clinical drug trials, phase II testing is performed on patients for whom the treatment is intended. A transplant is a device intentionally put into the body to serve a particular purpose.

Health Information Technology and Management Richard Gartee Pretest (True/False) (continued) The ER typically has ready access to a patient’s records in the HIM department. Speech recognition software can be taught to avoid past mistakes. A glucose monitor is an example of an instrument that facilitates point-of-care testing.

IT department may follow two different approaches to information systems: –Integrated systems approach uses systems from one vendor –Best-of-breed approach chooses software based on departmental needs

Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Health Information Technology and Management Richard Gartee Why Multiple Information Systems? (continued) Certain hospital departments may have more influence and select their own software Some equipment may come with own software required for operation –CAT scan, MRIs, PET, biomedical devices
