We worked with the Medical OB Department Committee to develop general guidelines (limiting the # any one MD could book in one day, then they developed "triage" guidelines to "bump" cases when more urgent medically indicated cases needed to be done). We are a 12 bed LDR, and book 4 cases per day, plus NST's. It took about 6 months for all of the acting out to stop, but runs very smooth now. Hopefully you have a good relationship w/your OB Dept. Chair. In the long run, it keeps their sch. cases from gettng cxl'd due to bed availablity and staffing.
