Data elements collected on large populations of individuals and stored in
databases are referred to as:
- Statistics
- Information
- Aggregate data
- Standard
(Ans - c. Aggregate data
Data about patients can be extracted from individual health records and combined as aggregate data. Aggregate data are used to develop information about groups of patients. For example, data about all patients who suffered an acute myocardial infarction during a specific time period could be collected in a database.

Community Hospital wants to compare its hospital-acquired urinary tract infection (UTI) rate for Medicare patients with the national average. The hospital is using the MEDPAR database for its comparison. The MEDPAR database contains 13,000,000 discharges. Of these individuals, 200,000 were admitted with a principal diagnosis of UTI; another 300,000 were admitted with a principal diagnosis of infectious disease, and 700,000 had a diagnosis of hypertension. Given this information, which of the following would provide the best comparison data for Community Hospital?
- All individuals in the MEDPAR database
- All individuals in the MEDPAR database except those admitted with a
- All individuals in the MEDPAR database except those admitted with a
- All individuals in the MEDPAR database except those admitted with a
principal diagnosis of UTI
principal diagnosis of UTI or infectious disease
diagnosis of hypertension (Ans - c. All individuals in the MEDPAR database except those admitted with a principal diagnosis of UTI or infectious disease
The Medicare Provider Analysis and Review (MEDPAR) file is made up of acute care hospital and skilled nursing facility (SNF) claims data for all Medicare claims. The MEDPAR file is frequently used for research on topics such as charges for particular types of care and DRGs. The limitation of the MEDPAR data for research purposes is that the file contains only Medicare patients. Community Hospital is excluding MEDPAR data of those patients with a principal diagnosis of UTI or infectious disease because these would not represent a hospital acquired condition (HAC) because the patients were admitted with those diagnoses.Community Hospital is looking for comparative secondary diagnosis data of Medicare patients from the MEDPAR file to compare their HAC rate for UTIs to the national average from the MEDPAR data. 2 / 3
Given the numbers 47, 20, 11, 33, 30, 30, 35, and 50, what is the median?
- 30
- 31.5
- 32
- 35
(Ans - b. 31.5
The median is the midpoint of a frequency distribution. It is the point at which 50 percent of observations fall above and 50 percent fall below. If an even number of observations is in the frequency distribution, the median is the midpoint between the two middle observations. It is found by averaging
the two middle scores, (x + y) / 2. In the example, the median is 31.5: ([30 +
33] / 2)
Data set in order from least to greatest: 11, 20, 30, 30, 33, 35, 47, 50
What formatting problem is found in the following table?
Community Hospital Admissions by Gender, 20XX Male 3,546 42.4 Female 4,825 57.6 Total 8,371 100
- Column headings are missing
- Title of the table is missing
- Column totals are inaccurate
- Variable names are missing
(Ans - a. Column headings are missing
A table is an orderly arrangement of values that groups data into rows and columns. Almost any type of quantitative information can be organized into tables. Tables are useful for demonstrating patterns and other kinds of relationships. Tables need headings for columns and rows, and they need to be specific and understandable.
