The Rationale behind Your Design Development

CPOE- Computer Provider Order Entry, along with Clinical Decision Support can enhance the safety of medicine prescription (Kuperman, et al., 2007). The rationale for the development of the physician order entry with CDSS comprises of process enhancement, support for cost-based decisions, support also for clinical decisions, as well as optimization of physicians' timeframe. Also, CPOE with CDS systems is considered one of the best ways to enhance health care service and improved safety of the patients. When the electronic records of the patients become increasingly accessible, the systems will inevitably become the method that medical care staffs will choose. It is a complex process creating a CPOE/CDS system. Indeed, some of them fail even after consuming a lot of resources and time.

How to Implement the CPOE/CDS System

CPOE presents many advantages and disadvantages. If it is not implemented in stages, one is likely to experience the full extent of its pitfalls. It must start with viewing it in the laboratory. The next steps include addition of dictations, viewing of images, basic chart and eventually graduated to CPOE system on form. Even with such pre-implementation precautions, the system can still confuse physicians...

The work-flow of the physicians may be slowed down in some situations. The system mandates a total of five clicks of the mouse for replacing just one non-formulary drug. This means that for a single average patient that needs up to 4 different substitution medications, the physician will have to click 20 times. This is a common occurrence. CDSS was used in order sets form into CPOE building a number of these specifically for individual service and bearing some guiding principles in mind. Adopting and implementing CPOE can take a long time because of the resistance by nursing staffs and physicians along with technical barriers. There should be training availed for all staffs and physicians in particular. The staffs at health facilities must fully understand the workings of the system. It is also important for the suppliers to provide a 24/7 technical system support after delivery to a health facility. It should be noted that training all employees on the workings and intricacies of the system will help the implementation process. Each department should create order sets which should be validated by the medical personnel that will use the system. The decision support rules fed into the system everyday is critical in its use. There should be enhanced interfacing of new standards in case of systems from different suppliers for purposes of transferring information among pharmacists, providers, pharmacy benefit overseers and payers. Technologies also need to be standardized. Standard technologies should be created to establish procedures for assessment and for shared details of dosages of medication, reactions and allergies. There is need for extended research to establish the implementation cost and the benefits of using the CPOE system. The essence of CPOE and its central role in reducing ADEs and medical errors should also be highlighted. Rural and small hospitals will also need some specialized attention based on research. Variation in the amount of resources may influence the adoption rate of CPOE. Moreover, a systematic review and a Meta analysis should be done to gain a precise measure of…
