telemetry orders

At my facility, the current orders for telemetry monitoring calls for 24hr, 48hr, or 72hr. But as you know, some patients are here for days or weeks. I recently had a patient who had been in hospital for 25 days and the order had originally been for 72 hours. So this patient had the monitoring for 25 days with no significant events. The protocol states the monitoring unit is to call the charge nurse on each floor and tell them what orders need to be re-ordered or canceled each morning, but that is not happening. The mentioned patient's order had expired for around 22 days. In another facility where I worked, we used the same orders, but at the end of the allotted time, the RN was allowed to cancel the order if there were no events. Do any of you use these same types of orders and if so, what are your protocols? Thanks,
