How can we avoid duplicate data collection while submitting the form?

we are conducting clinical survey with group of data collectors. There is a possibility to collect data multiple time from same patient. Is there any possibility to avoid this situation with kobo.

Our need is when we submit a duplicate data alert or pop up message should display already entered. Anyhow duplicate data should not save in the server.

Kindly please be informed that KoBoToolbox at the moment does not support this feature. FYI,

Maybe you could be cautious while collecting data (where enumerators are allocated with specific respondents and they collect data from the same i.e. not going out of the samples they have been provided). The other option is during data management (where the data manager cleans the repeated samples if there are any looking at key identifiers such as name etc. set while developing the survey tool).

Thank you for your response.
