Preventing medication errors with MARS?

I am a new nurse working at a facility in which we use paper MARS. I am wondering if there are any other nurses out there who use it to ask what does your facility do prevent medication errors? We have orders e-mailed, printed out and filed in client's charts, have made a checklist that is done weekly to follow through that staff and clients are initialing, etc. I am the one who transcribes orders onto the MARS and distribute the morning and afternoon medications, and then bag for evening and weekend medications. The small baggies that we use I include client initials, time of administration, date, name of drug and dosage, and baggies are place in envelopes with the day on it. The therapists administer medications during the evenings and weekends.

Is there anything else that you do for patient safety?
