Survey Data

(Meisha Mandal) #1

Does OHDSI support survey data? I am trying to look at frequency of response data for surveys and obtain information on respondents who selected specific answers. There appears to be a value_as_string field in the Observation table but when I looked at the sample data in Atlas and Achilles I was not able to find examples of concepts that could be broken down by answer choice. Is this just because the sample data doesn’t contain concepts of this nature? If I wanted to use OMOP for survey data would I be able to track respondents’ answer choices?

I also noticed that there appears to be a proposal for a "Survey"table related to this (https://www.ohdsi.org/web/wiki/doku.php?id=documentation:next_cdm:add_survey). Is this something that is in the works?

Hi @mmandal
SURVEY_CONDUCT table is already included in CDM.
It’s better to standardize answers using value_as_concept_id, for example “Yes”
