Nurse Usecase Diagram and Table - SENG-350-2024-fall/Team3 GitHub Wiki
| Description | Tool for patients to compare real-time capacity of nearby EDs, optimizing service and reducing wait times. |
|---|---|
| Actors | Nurse, Patient, Mister Ed system, ED staff |
| Assumptions | The triage system accurately assesses conditions. Mister Ed gets real-time updates from Nurses. Patients have internet access. ED staff receive notifications about critical cases. |
| Steps | 1. Patient reports symptoms on Mister Ed. 2. System collects medical history. 3. Mister Ed identifies high-risk patients. 4. Patient is instructed to go to the ED, and nurses are notified. 5. Nurses prepare for the patient. |
| Variations | - If EDs are full, patients may wait at home or seek alternative care. - Patients can filter results by distance. |
| Non-Functional | - System must scale for large user numbers. - Quick data handling for real-time updates. - 24/7 availability required. - Must integrate with hospital systems. |
| Issues | - Inaccurate real-time data can mislead patients. - Patients may have mobility challenges. - Hospitals may not share data, limiting effectiveness. |
| Description | Conduct a virtual assessment of the patient's symptoms to determine the appropriate course of action. |
|---|---|
| Actors | Nurse, Patient |
| Assumptions | Patient has access to the internet and is registered in the system. |
| Steps | 1. Patient initiates virtual triage. 2. Nurse conducts the triage. 3. Nurse assesses symptoms and provides recommendations. |
| Variations | If the nurse determines the patient needs in-person evaluation, they will refer the patient to the ED. |
| Non-Functional | The system should be accessible and responsive during peak hours. |
| Issues | Internet connectivity issues may affect the triage process. |
| Description | Provide medical advice and guidance to patients who contact the hotline. |
|---|---|
| Actors | Nurse, Patient |
| Assumptions | Patient contacts the nurse through a functioning hotline. |
| Steps | 1. Patient calls the hotline. 2. Nurse answers the call. 3. Nurse provides advice based on the patient’s concerns. |
| Variations | If the nurse determines the patient requires further assistance, they will advise a visit to the ED or a primary care clinic. |
| Non-Functional | The hotline should have minimal wait time for patients. |
| Issues | High call volume may lead to longer wait times for patients. |
| Description | Nurses assess patients who arrive at the ED to determine the urgency of their condition and the type of care required, ensuring timely treatment and resource allocation. |
|---|---|
| Actors | Nurse, Patient, ED staff, Doctor |
| Assumptions | Patients provide accurate information about their symptoms. Nurses are trained to assess conditions effectively. The system supports efficient patient flow management. |
| Steps | 1. Patient arrives at the ED and checks in. 2. Nurse greets the patient and gathers initial information about symptoms and medical history. 3. Nurse performs a preliminary assessment, measuring vital signs and observing the patient’s condition. 4. Based on the assessment, the nurse categorizes the urgency level (e.g., critical, urgent, non-urgent). 5. If urgent care is needed, the nurse notifies the doctor and prepares the patient for immediate treatment. 6. For non-urgent cases, the nurse provides instructions for care and may schedule follow-up appointments. 7. The system logs the assessment and updates patient records for future reference. |
| Variations | - If the patient is critical, they may be fast-tracked for immediate treatment. - If the ED is busy, triage protocols may require the nurse to prioritize patients based on urgency. |
| Non-Functional | - Process must be efficient to reduce patient wait times. - The assessment system should provide quick access to patient history and previous visits. - Training programs must be in place to ensure nurses are up to date on assessment techniques. |
| Issues | - Misassessment of urgency can lead to delayed treatment. - Patients may withhold information, impacting assessment accuracy. - High patient volume may strain resources and affect care quality. |
| Description | The system notifies patients waiting for care in the ED when it is their turn to be seen, allowing them to wait comfortably at home or in a designated area until called. |
|---|---|
| Actors | Nurse, Patient, Mister Ed system, ED staff |
| Assumptions | Patients have provided accurate contact information. The system can track patient wait times and notify patients in real-time. ED staff are trained to manage notifications. |
| Steps | 1. Patient arrives and checks in, receiving a unique identifier. 2. Nurse enters the patient’s details into the system. 3. The system assigns a wait time based on urgency and current ED capacity. 4. When the patient's turn is approaching, the system sends a notification via SMS or app alert. 5. Patient receives notification and prepares to return to the ED. 6. Upon arrival, the patient checks in again, and the nurse confirms their readiness for treatment. 7. The system updates patient status and logs the interaction. |
| Variations | - If the patient does not respond to the notification within a specified time, a reminder notification may be sent. - If the patient is unable to return in time, they may contact the ED to reschedule. |
| Non-Functional | - Notifications must be sent promptly to minimize delays. - The system should handle high volumes of notifications during peak times. - User interface should be intuitive for patients to access their status easily. |
| Issues | - Delays in notifications could cause patient frustration. - Technical issues may lead to missed notifications, affecting patient flow. - Patients may not have reliable means to return in time, leading to missed appointments. |
