Based on the readings in the principles of practice in systems engineering, needs analysis is broken into four steps. According to Wu, Klein & Stone (2006), these steps are colloquially referred to as DMOD, and the first step is the diagnosis. In the diagnosis step, the patient is either subjected to ancillary testing or physical examination to identify the disease through its causative agents. After the diagnosis has been carried out, the results are documented in electronic medical records (EMR). The second step is medication, and at this step, the care provider collects and adjudicates the patients' medication history appropriately in a process commonly referred to as medication reconciliation. After the medication reconciliation is successively accomplished, the order is made and thus, the third step. Every patient must have orders placed even in situations where only follow-up care is needed. The final step is to depart where a departing document is provided to the patient. The document contains instructions as well as education on measures to take after leaving the hospital or any other health care facility. All four steps must be accomplished based on the electronic medical records system.
Performance requirement validation is the use of quality analysis as well as quality assurance to affirm that a system is optimized and serves the designed need effectively (Theodorsson & Magnusson, 2017). I work as a general lab technician at Massillon Hospital in Stark County, Ohio. Most of my work is specimen processing, and the performance requirement is that the blood collecting container must be filled 10% with the specimen. The tube should be inverted ten times for essential mixing. We then allow the blood to clot for twenty minutes, and the sample is always transferred to the secondary container through aspiration and not pouring.
Delegate your assignment to our experts and they will do the rest.
