Table 1 Logic Used to Trigger the Overdue Alerts for the Liver Transplant Patients

	Time since Transplant
	0 - < 3 months	3 - < 6 months	6 mo – < 4 years	> = 4 years
Routine lab testing schedule	At least weekly	Every 2 weeks	Every month	Every 3 months
Alert if it has been at least ____ since last result	14 days	21 days	45 days	120 days
Repeat overdue alert every ___days after the initial alert until new lab result obtained	3 days	3 days	14 days	14 days

Note: For example, patients that underwent transplantation during the previous three to six months are expected to get their blood tested every two weeks. If a patient had no new immunosuppression drug level for 21 days (i.e., two weeks and a seven-day buffer), then an “overdue for immunosuppression drug level” alert was triggered. Alerts continued to be delivered every 3 days until a new result was saved to the EHR. The same logic applied for creatinine results.
