Increase healthcare efficiency and productivity - ANSWER Driving Forces
Behind Health Informatics
improve healthcare quality resulting in improved patient safety - ANSWER
Driving Forces Behind Health Informatics
reduce healthcare costs - ANSWER Driving Forces Behind Health Informatics
improve healthcare access with technologies such as telemedicine and online
scheduling - ANSWER Driving Forces Behind Health Informatics
improve coordination and continuity of care - ANSWER Driving Forces Behind
Health Informatics
improve medical education of clinicians and patients - ANSWER Driving Forces
Behind Health Informatics
standardize medical care - ANSWER Driving Forces Behind Health Informatics
What are the barriers of HIT adoption (not enough...) - ANSWER time to learn
new systems, useful information, skilled workers to manage systems, funding,
interoperability
, What are the barriers of HIT adoption (too much...) - ANSWER change in office
workflow and business processes, security required for HIPAA compliance,
legal red tape between hospitals and referring doctors, behavior change, hype
integers - ANSWER any whole number
floating point numbers - ANSWER decimals and nonterminating numbers
characters - ANSWER any letter "a-z"
strings - ANSWER combination of letters/ words found in the system code
Structured data - ANSWER data that is coded (ICD-9 codes)
Unstructured data - ANSWER free text or natural language
What is interoperability? - ANSWER the ability to integrate for sharing with
health information organizations, integrate with other applications, integrate
with local, state, and federal governments.
what is blocking? - ANSWER The opposite of interoperability; not wanting to
share
What is a clinical data warehouse (CDW)? - ANSWER a centralized,
standardized, integrated repository of data extracted from numerous source
systems including HIPAA compliant EHR information
What are the main functions of CDW? - ANSWER to evaluate a critical clinical
process and cost estimates, analyze potential solutions, track infections, and to
report trends to public health
Why does HIT fail? - ANSWER (1) HIT is an attractive system to a healthcare
system, but it isn't completely realistic; (2) There are serious "ups and downs"
reported for some programs; (3) There is a large gap between healthcare data
generated and information (semantic gap)
What is Cloud computing? - ANSWER Application that is up in the cloud that is
not localized to a specific site, utilize the internet to connect to it. Pay a service
and get a software that works the way you want it to work
What are the REST Operations? - ANSWER (1) GET: accessing a resource
(2) POST: creating a resource
(3) PUT: updating a resource
(4) DELETE: deleting a resource
