Recruit subjects via mail

Note

Recruitment via mail is only possible if it has been configured by the study coordinator.

  1. Click on Studies on the front page. Then click on Execution in the field Status to only show studies that are currently recruiting.

  2. Click on Recruitment next to the study you want to recruit subjects for

  3. Go to the Mail tab

  4. Enter the number of subjects that you want to contact

  5. Click Send

Hint

The section Previous mails will appear after you have sent your first batch of mails. It lists all contacted groups allowing you to remind those potential participants of a group who did not respond yet. Please note, that this reminder can only be triggered once per group. It will send out the current invitation mail text with a prefixed e-mail subject indicating it as “Reminder/Erinnerung”.

Make appointments for sessions

Note

This describes setting up appointments for the participants manually by Castellum users. There is also a guide on how to use the optional external scheduler feature in Castellum that offers potential participants to select appointments by themselves: Make appointments with the external scheduler.

If you are recruiting for a study that has at least one session Castellum allows you to set up appointments for the participants:

  1. In recruitment click on Contact in the Open list or on Review in the Participating list to get the details of the participant. Go to the tab Appointments.

  2. The tab Appointments offers a date and time field for every session of the study. Click and populate those session fields that need to be appointed at this moment.

    Hint

    Study execution provides the same feature to make appointments with participating subjects. Thus, this can also be done by study conductors.

  3. The Calendar button in the Appointments tab opens a new window and allows you to have a look at all already appointed sessions of the study.

Warning

There are cases in which for example two subjects will be tested at the same time. For that reason castellum does not prevent you from booking overlapping appointments. You have to make sure that the requied staff and resources are available yourself.

Cleanup open list in recruitment

The open list in study recruitment can become quite large and noisy if you are waiting for many responses and/or failed to reach many potential participants. Therefore, Castellum provides a cleanup feature:

  1. Scroll down to the end of the open list in recruitment and click on Cleanup

  2. Decide if you want to cleanup the complete open list (All) or only those potential participants whose status is marked as Awaiting response for more than 10 days. The third option allows you to run potentially modified recruitment filters on the list (Mismatch). This allows to cleanup those who do not match anymore. A click on either of these buttons will start the cleanup process.

  3. After cleaning up the affected potential participants will be moved to the Excluded list with the additional tag Excluded by cleanup. This may allow you to reconsider contacting some of them.

The open list also gets quickly populated by mail recruitment (if set up) with many potential participants with the status Awaiting response. Thus, Castellum additionally allows to cleanup by mail batches:

  1. Go to the Mail tab in recruitment and select an appropriate entry of the Previous mails list. Select Cleanup.

  2. Confirm that you want to cleanup all potential participants of the mail batch who did not respond.
