1. Accident and Emergency process: The following narration is the result of an interview with an Accident and Emergency (A&E) nurse. For the purposes of illustrating the process, a scenario involving a person presenting to A&E with a wound to their limb was chosen. The A&E streaming guidelines provide medical practitioners and nurses with a 'roadmap' for streaming patients through the A&E based on their diagnosis. When a person arrives at the A&E reception, they are asked to describe their injury and the circumstances of the injury. In this case, the injury is a cut to the arm. The nurse also requests the name, address and date of birth of the patient so their patient record can be retrieved. If the patient is a new patient, the health insurance number is requested and added to the patient record. A new case record is created with a unique case number, patient name and date of birth. After answering a checklist of questions, the patient is asked to go to the x-ray treatment room. The nurse provides this recommendation based on consulting the A&E streaming guidelines. The medical practitioner reviews the patient record to understand pre-existing conditions and the description of the injury provided at reception. The patient is x- rayed, and the medical practitioner uploads the x-ray and procedure details to the patient record and then updates the case record with the medical practitioner's name and details of any bone trauma caused by the limb. If the trauma is minimal, the patient is asked to proceed to the treatment room for suturing after consulting the A&E streaming guidelines. The medical practitioner reviews the patient record and case details. The patient is given a local anaesthetic injection and the wound is sutured. The medical practitioner uploads procedure details to the patient record and updates the case record with the medical practitioner's name and details of the procedure. After thirty minutes of recovery on a hospital gurney, the patient is discharged after consulting the A&E streaming guidelines. Post operative care is advised. Each week, a hospital administrator reviews the procedure details from each case and creates two invoices. One invoice is sent to the patient and the other to the Health Insurance Company. When payments are received, the remittance advices, invoices and the bank statement are reconciled on a monthly basis
