RATIONALES GRADED A+
⩥ Force Field Analysis.
Answer: A method for listing, discussing,
and assessing the various forces for and against a
proposed change by analyzing all of the forces impacting on the change
and weighing the pros and cons. Used to develop strategies to reduce the
impact of the opposing forces and strengthen the supporting forces.
(Kurt Lewin)
⩥ Adaptation Curve.
Answer: Innovators - pull the change
Early Adaptors - will try new ideas but careful
Early Majority - careful but accept change quicker
Late Majority - will accept change after majority
Laggards - accept change only after new way
becomes tradition
⩥ Shannon's Information Theory.
,Answer: Evaluates the effectiveness of comminucations systems.
Elements include:
-Signal to noise (S/N) ratio
-Channel capacity (max information transmitted
with minimal error)
-Entropy (amount of energy, code, or bits needed
for storage or communication of one
signal)
⩥ Weiner's Attribution Theory.
Answer: Explains people's behaviors and the cause for the behavior by
observing behaviors, judging that the behavior was intentional, and
attributing the cause for the behavior on internal or external causes.
⩥ Data Archiving.
Answer: Moving data from current storage to a seperate device for long-
term storage of data that is no longer necessary for active use.
⩥ Low Level Data Input Error.
Answer: Wrong sequence of steps triggers an alarm/hardstop until
correct; fairly easily corrected
⩥ Moderate Level Data Input Error.
,Answer: Inputting data incompatible with the system
⩥ High Level Data Input Error.
Answer: The system is unable to make a decision about the corrective
action or unable to correctly interpret outcomes data.
⩥ Cache Memory.
Answer: Stores in-process data for quick retrevial
⩥ Random Access Memory (RAM).
Answer: Temporary memory used when working on a task (lost when
turned off)
⩥ Read Only Memory (ROM).
Answer: Permanent or semi-permanent memory that stores saved data.
Essential to the OS
⩥ Virtual Memory.
Answer: Temporary use of the hard drive for memory when many
programs are running at the same time.
⩥ Small Computer System Interface (SCSI).
, Answer: An interface that provides the means for an attachment of
additional hardware devices. Ex. Scanner
⩥ Integrated Drive Electronics Controller (IDE).
Answer: Primary interface for the hard drive, CD-ROM, and DVD drive
⩥ Peripheral Component Interconnection Bus (PCI).
Answer: Connects plug-in components to the computer with a series of
slots on the motherboard. Ex. mouse, keyboard
⩥ Basic Input/Output System.
Answer: Boot firmware. Type of ROM that the computer uses when it
boots up.
⩥ Qualified EHR.
Answer: Contains demographics, clinical health information, medical
history and problem lists. Capable of providing support for clinical
decisions and entry of physician orders.
Has the capacity to capture and query information relevant to healthcare
quality and exchange electronic health information with and integrate
information from other sources.
⩥ Certified EHR Technology.
