1. Purpose of data collection: For research, for public health surveillance, or others.
The research project I am involved in is a vaccine trial that will assess the immunogenicity and safety of the Vaccine in healthy adults.
2. Was it primary or secondary data collection?
Both types of data collection were performed.
– Hospital data collection form
– Medical records/ Medical charts
– Laboratory results
– Interviews
– oral histories
– Diary card
3. Methods used for data collection
– EDC (Electronic Data Capture) system: Used to collect, store, and manage research data electronically in a secure.
– ePRO (electronic Patient-Reported Outcomes) mobile application: Used to collect patient-reported outcomes (Local and systemic reactogenicity) during the conduct of clinical trials.
4. Were there any problems that occurred regarding data collection?
– Data Quality: It can come from a variety of sources, including data entry errors or datasets that may have missing, inconsistent, or invalid values that reduce reliability. This can be due to human error, technological failures, or flaws in collection methods.
– Complicated forms can lead to nonresponse or respondents filling in answers at random simply to complete the survey.
– Literacy comprehension barriers.
– Language comprehension barrier.
– Data Integration: Internal systems, third-party applications, and external data sources.
– Insufficiently trained staff.
– Lack of understanding of context.
– Data inaccuracy – Even complete datasets can contain incorrect values due to human data entry mistakes, respondent misreporting, technology errors, flaws in measurement methods, and more.
– Data collected may have compatibility issues around file formats, metadata standards, and barriers to consolidation.
