Five of the included studies compared same day scheduling where most of the calendar is open for today’s inquiries with traditional scheduling where only a couple of doctor's appointments are not scheduled. This kind of same day scheduling will:
- probably lead to reduced wait time
- possibly increase the number of patients meeting for their appointments and improve continuity of care
It is uncertain whether same-day-scheduling has any effect on the other outcomes.
One study compared two versions of same day scheduling, both holding a large portion of the calendar open for today’s inquiries. One system keeps 75 per cent open and the other keeps 40-5o% open. It is uncertain whether more or less available hours have different effect on the relevant outcomes.
