Chapter 21 Flashcards
A growing number of governmental agencies allow researchers access to Data sets that have had all identifying information removed. What are these data sets called?
Anonymized data sets (Deidentified data sets)
The CDC provides data from several studies including:
1) National Health and Nutrition Examination Survey (NHANES)
2) National Health Interview Survey (NHIS)
3) Behavioral Risk Factor Surveillance System (BRFSS)
Should organizations who offer their data to the public become co-authors?
No, but they should be acknowledged
A request for access to a private data set is most likely to be granted when
The new researcher has some existing connection to the original researcher (like a student).
If private data sets will be shared who needs to approve the data sharing plan?
The ethics review committees of both institutions.
Should the original researchers of the privately held data become co-authors?
Yes, they expect to become co-authors.
Researchers working with clinical patient records in the United States must be prepared to comply with:
The Health Insurance Portability and Accountability Act (HIPAA) privacy rule
What is a major limitation of using existing clinical records
Patient records are often incomplete
If the research question requires complete information about symptoms or medication usage or other details, then:
A primary study design may be necessary
Bioinformatics typically focuses on
Analysis of molecular-level data.
Give five examples of big data:
1) Electronic health records or electronic medical records
2) Billing records, which use ICD codes based on diagnoses or CPT codes based on procedures
3) Lab records, which use LOINC codes
4) Medication records, which use NDC codes
5) Social media posts and other information from the Internet
6) A diversity of other sources
What is text mining or data mining?
Used to extract particular phrases from large sets of records
Additional approval by an ethics committee at the institution where the secondary analysis will be conducted is often not required for publicly available data when several conditions are met:
1) The data was collected after approval by a trusted organization’s research ethics committee
2) The data set contains no individually identifying information
3) The data to be analyzed is publicly available
When there is any doubt about whether review is required, who should be consulted?
The institutional Review Board
