Description:

Computerized physician order entry (CPOE), is a system that allows doctors to electronically prescribe medical orders for their patients. This could be any form of medical orders, i.e. prescriptions, lab tests, referrals, etc. Instead of writing out these orders onto a piece of paper a doctor will enter them into a computer. The order will then be electronically sent to the person or department in charge of executing the order. With proper use it can reduce errors by minimizing the ambiguity of hand-written orders, but a much greater benefit is seen with the combination of CPOE and clinical decision support tools.


Benefits:

  • There will be a faster communication between the doctor and the constituents
    • Orders can be electronically sent instead of through fax
  • Medical errors will be detected sooner
    • The CPOE system will be able to detect any drug complications, dosage errors, etc.
  • Accurate current information of the patient
    • Reviewing patient information would be done with a click
  • If doctors are electronically ordering prescriptions there will not be any discrepancies due to poor penmanship
  • If ordering is done electronically a pharmacist will be able to track inventory faster and will be more up to date
  • Reduction of costs
    • Labor, paper, etc.
  • Reduce redundancies in medication and lab work
  • Use of clinical support system to make decisions on treatments
    • Doctor's will be able to track prior orders from different patients and relate them to new patients


Problems:

  • Initial start up cost
    • The cost of a new system can be expensive $3 - $10 million on the hospital level depending on size
  • Inexperience and errors of medical team
  • Training cost
  • System demands
