Primary Outcome Measures:
  • Reduce concomitant orders for warfarin and tmp/smx [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Determine if computerized stop order will increase risk for inadvertent cessation of warfarin [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
  • Determine if computerized stop order will increase risk of delay of treatment with tmp/sulfa when determined to be necessary for treatment [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
