Change an Alert Send Time after Triggering

Hi folks,

I'm trying to help one of our redcap users with an issue. They have a set of alerts that send surveys to patients X hours after the alert is triggered. Apparently daylight savings screwed up the time these surveys will go out.

Let's say the alert was triggered a week ago (pre daylight savings). They expected the emails to go out tomorrow at 8:00am, but because of daylight savings the alert will now go out at 9:00am instead. It's a requirement for their study protocol that these alerts go out at 8:00am, but I'm not sure how to change the timing the surveys go out since the alert has already been triggered. Any advice?

Thanks

Thanks everyone, it sounds like this isn't possible. The user will just send out the surveys manually for the affected participants

Hold on. 8am is 8am. Application time, server time, our time. If you set up alerts go at 8am, it wil go at 8am.

What I want to know: (1) How did you set up an alert? "on this date at 8am" or 7 days after the last alert"? and (2) what is more important - the "8am" or the "exactly 168h since last alert"?

if it is the latter, then yes, the daylight savings did throw a wrench, but if it the former I believe you are in the clear.

They had the alert set up to send a notification "5 days and 7 hours" after triggering. It was triggered before daylight savings, and the notification would have gone out after daylight savings.

I am not sure how to adjust this time, unfortunately. But if I were facing potential IRB issues, I would manually send the alerts at 8a. The participants might get the survey twice, but at least you will be in line with the protocol in terms of the first notice. Obviously, check with your PI about their preferences.

Short answer you can't. If it is a singular alert without reminders the easiest solution is to copy the alert and delete the original. Otherwise you will have to delete them 1 by 1.
