1. Which of the following best defines data?
. Processed results presented in charts
. Interpreted trends used for decision-making
. Raw numbers collected from observations
. Summarized findings from analysis
- ANSWER — Raw numbers collected from observations
2. Which statement best describes information?
. Unprocessed numerical values
. Data stored without context
. The application of analytical techniques to data for interpretation
. Random facts without meaning
- ANSWER — The application of analytical techniques to data for
interpretation
3. Validity - ANSWER § Accuracy of the data
§ Ability of the data to measure the attribute it is intended to measure
§ Example: if the researcher is using a written questionnaire to collect data, he or
she will pretest it by giving it to someone how may have been included in the
,subject population in order to determine whether it is well written, clear and
inclusive of everything the researcher is looking for
4. Face validity - ANSWER · Does the metric appear to measure the
quantity it was intended to measure?
· Often assessed via expert opinion
· Weakest form of validity measure, but should be the first steps in assessing
validity of a new test or metric
5. Content validity - ANSWER · Are the components of the metric
necessary and sufficient to measure the quantity?
· In survey design, this content validity ensures that there are not irrelevant
questions
6. Construct validity - ANSWER · Is the measurement tool capturing the
construct to be measured?
· In survey design, this may be measured by asking similar questions about a topic
(or construct) to ensure consistency in the responses
7. Criterion validity - ANSWER · Does the metric agree with an accepted
gold standard for measuring the same quantity?
· A new less expensive lab test may be compared against another accepted test for
measuring the same quantity. If test results agree then the new test has criterion
validity
8. Reliability - ANSWER Repeatability or reproducibility of the results
,§ Major question is: can another researcher reproduce the study using a similar
instrument and get similar results?
9. Inter-rater relaibility - ANSWER measures the reproducibility or
consistency of the metric between 2 different raters
10. Intra-rater reliability - ANSWER measures the reproducibility or
consistency of the metric between 2 different time points using the same
rater
11. Internal data (sources of HC data) - ANSWER § Electronic health records
§ Claims and billing data
§ Patient satisfaction surveys
12. External data (sources of HC data) - ANSWER § Registries (may be both
internal and external)
§ Statewide databases
§ Medicare claims data
13. Diagnostic data (sources of HC data) - ANSWER § CMS pays for
inpatient services provided to Medicare patients via an inpatient
prospective payment system (IPPS)
The CMS uses 2 code groupings to organize data and process payment
, 14. Procedural data (sources of HC data) - ANSWER § Outpatient
prospective payment system (OPPS)
· Payment for Medicare hospital outpatient services
· HCPCS codes are assigned to Ambulatory Payment Classifications (APC) for
payment
§ Updated on a calendar year basis
§ APCs have weights that ae used to derive the payment for each service or set of
services
15. Pharmacy data (sources of HC data) - ANSWER § National drug codes
§ Therapeutic classification groups
§ RxNorm
16. Administrative data (sources of HC data) - ANSWER § Revenue codes
§ Place of service codes
§ Claims processing codes
§ Relative value unit data
17. Research - ANSWER is an inquiry process aimed at discovering new
information about a subject or revising old information. It includes
investigation or experimentation aimed at the discovery of new facts,
revision of accepted theories or law in light of these new facts, or practical
application of the new facts. Health information research examines all
aspects of health and can include studies on human subjects as well as
public policy. The goal of health information research is to
