When a patient shows signs of a pulmonary embolism, clinicians need to act fast. This tool handles the clinical risk assessment so you don't have to do the math manually. It takes patient information like heart rate, surgery history, and symptoms to calculate the pre-test probability score. It also checks if a patient meets specific rule-out criteria to see if you can safely skip further testing. If more tests are needed, the system points you toward the right diagnostic step, like a CTPA or D-dimer test, following standard ESC/ATS guidelines. You can find this tool in the Vinkius catalog to keep your clinical decisions accurate and consistent. It turns a tedious manual process into a quick, reliable check, letting you spend more time on patient care. It ensures that even in a busy emergency department, the logic remains sound and the recommendations stay current with medical standards. By automating the scoring, it removes the risk of human error during high-stress triage moments. It bridges the gap between raw patient data and actionable clinical plans. ## Tools ### evaluate_perc_prob Evaluates whether a patient meets the Pulmonary Embolism Rule-out Criteria (PERC). This helps you decide if you can safely skip further testing. ### calculate_wells_score Calculates the Wells Score for Pulmonary Embolism based on seven specific clinical criteria. It helps determine the pre-test probability for your patient. ### determine_diagnostic_pathway Recommends the next diagnostic step like CTPA or D-dimer testing. It follows standard ESC/ATS clinical guidelines for accuracy. ## Prompt Examples **Prompt:** ``` Calculate the Wells Score for a patient with tachycardia and recent surgery. ``` **Response:** ``` ### Patient Risk Assessment **Wells Score Calculation:** * **Tachycardia:** +1.5 * **Recent Surgery:** +1.5 * **Total Score:** **3.0** **Risk Category:** Low Probability Based on this score, the patient is categorized as low probability for pulmonary embolism. ``` **Prompt:** ``` What should I do if a patient has a high Wells score? ``` **Response:** ``` ### Recommended Diagnostic Path For patients in the **High Probability** group, the following actions are recommended: * **Primary Action:** Perform **CT Pulmonary Angiography (CTPA)**. * **Rationale:** This is the standard of care for high-probability cases to confirm the presence of a pulmonary embolism. *Note: Always correlate with clinical presentation and local hospital protocols.* ``` **Prompt:** ``` Check if a 25-year-old patient with no symptoms passes the PERC rule. ``` **Response:** ``` ### PERC Rule Evaluation **Patient Profile:** 25-year-old, asymptomatic. **Evaluation Results:** * **Criteria Met:** Yes * **Result:** **PERC Negative** **Conclusion:** The patient meets all criteria and is considered PERC negative. No further testing for pulmonary embolism is required at this time. ``` ## Capabilities ### Calculate Wells Score Determine pre-test probability for pulmonary embolism based on seven clinical criteria. ### Evaluate PERC Criteria Check if a patient qualifies for rule-out criteria to avoid unnecessary testing. ### Identify Diagnostic Pathways Get the specific next step like a CTPA or D-dimer test based on current guidelines. ### Assess Clinical Risk Categorize patients into low or high probability groups for faster triage. ### Align with ESC/ATS Standards Ensure every diagnostic recommendation follows established medical protocols. ## Use Cases ### Emergency Triage A patient has tachycardia and recent surgery. The agent uses `calculate_wells_score` to identify them as high risk. ### Routine Screening A 25-year-old with no symptoms needs a check. The agent uses `evaluate_perc_prob` to confirm they can be ruled out. ### Guideline Adherence A clinician isn't sure if they need a D-dimer or CTPA. The agent uses `determine_diagnostic_pathway` to clarify the next step. ### Clinical Training A resident uses the agent to see how different symptoms affect the Wells Score and the resulting diagnostic path. ## Benefits - You get consistent pre-test probability results by using `calculate_wells_score` to automate the math for every patient. - You can quickly rule out pulmonary embolism by using `evaluate_perc_prob` to see if a patient meets the PERC criteria. - You stay compliant with ESC/ATS standards by using `determine_diagnostic_pathway` to get the correct next step. - You reduce the cognitive load on your staff by letting the agent handle complex clinical scoring in real-time. - You speed up emergency triage by getting instant diagnostic recommendations for high-risk pulmonary embolism cases. ## How It Works The bottom line is that you get instant, guideline-compliant diagnostic recommendations for pulmonary embolism based on real-time patient data. 1. Input patient symptoms and clinical data into your agent 2. The Connector processes the data against Wells and PERC rules 3. You get a risk score and a recommended diagnostic plan ## Frequently Asked Questions **What does the Wells PE Calculator do?** The Wells PE Calculator helps you quickly assess pulmonary embolism risk. It automates the calculation of the Wells Score and checks if patients meet rule-out criteria, providing a clear path for your next diagnostic steps. **Can this help me decide between a D-dimer and a CTPA?** Yes. By calculating the risk score and following ESC/ATS guidelines, the tool suggests whether a patient requires a D-dimer test or a CTPA based on their specific clinical data. **How does the Wells PE Calculator use clinical guidelines?** It incorporates established ESC/ATS guidelines into its logic. When you provide patient data, it ensures the recommended diagnostic pathway matches current medical standards. **Can I use the Wells PE Calculator for emergency triage?** It is designed for high-pressure environments. It helps clinicians quickly categorize patients into risk groups, allowing for faster triage and more efficient resource allocation. **Does the Wells PE Calculator handle PERC rule-out criteria?** Yes, it evaluates whether a patient meets the Pulmonary Embolism Rule-out Criteria (PERC). This helps you determine if you can safely skip further testing for low-risk patients. **How does this help with pulmonary embolism diagnosis?** It streamlines the transition from symptoms to a diagnostic plan. It removes the manual math of scoring and provides a clear, guideline-based recommendation for the next test. **What clinical criteria are used in the Wells Score?** The tool assesses seven criteria including DVT signs, PE as most likely diagnosis, tachycardia, recent immobilization or surgery, previous VTE history, hemoptysis, and active malignancy. **How does the tool recommend next steps?** By using `diagnosticPathwayTool`, it follows ESC/ATS guidelines to suggest actions like CTPA, D-dimer testing, or discharge based on risk levels. **Does this tool support the PERC rule?** Yes, the `percRuleTool` allows clinicians to evaluate if a patient can be safely ruled out for PE using clinical observation.
