Langcare Langcare MCP Fhir Procedure Note Template

Procedure Note Template

Overview

Generate pre-populated procedure documentation templates from FHIR data. Pull patient demographics, procedure indication from active conditions, relevant pre-procedure labs (coagulation studies, platelets, hemoglobin), allergy list, and current anticoagulant status. Include required elements: informed consent verification, time-out documentation, procedure details, specimen handling, complications, and post-procedure orders. Support common bedside procedures: central venous catheter, arterial line, intubation, lumbar puncture, paracentesis, thoracentesis, chest tube, foley catheter, and NG tube.

FHIR Resources Used

Instructions

Step 1: Retrieve Patient Demographics

Tool: fhir_read
resourceType: "Patient"
id: "[patient-id]"

Extract: name, DOB, age, gender, MRN for procedure note header and patient identification band verification.

Step 2: Identify Procedure Indication

Tool: fhir_search
resourceType: "Condition"
queryParams: "patient=[patient-id]&clinical-status=active"

Match the stated procedure to an active condition as the indication. Common mappings:

• Central line: difficult IV access, need for vasopressors, TPN, prolonged IV antibiotics
• Arterial line: hemodynamic instability, frequent ABG monitoring
• Intubation: respiratory failure, airway protection
• Lumbar puncture: meningitis workup, subarachnoid hemorrhage evaluation
• Paracentesis: ascites (tense, diagnostic)
• Thoracentesis: pleural effusion (diagnostic or therapeutic)
• Chest tube: pneumothorax, hemothorax, empyema
• Foley catheter: urinary retention, strict I&O monitoring, perioperative
• NG tube: bowel obstruction, GI decompression, medication administration

Step 3: Pull Pre-Procedure Labs

Tool: fhir_search
resourceType: "Observation"
queryParams: "patient=[patient-id]&category=laboratory&code=http://loinc.org|5902-2,http://loinc.org|6301-6,http://loinc.org|777-3,http://loinc.org|718-7,http://loinc.org|3173-2&_sort=-date&_count=20"

Critical pre-procedure LOINC codes:

• 5902-2: PT (Prothrombin time)
• 6301-6: INR
• 3173-2: aPTT (Activated partial thromboplastin time)
• 777-3: Platelet count
• 718-7: Hemoglobin
• 4544-3: Hematocrit

Flag if:

• INR > 1.5 (relative contraindication for most invasive procedures)
• Platelets < 50,000 (increased bleeding risk)
• Platelets < 20,000 (contraindication without transfusion)
• aPTT > 1.5x control
• Hemoglobin < 7 (consider transfusion before elective procedure)
• Labs > 24 hours old (recommend recheck)

Step 4: Check Allergies

Tool: fhir_search
resourceType: "AllergyIntolerance"
queryParams: "patient=[patient-id]&clinical-status=active"

Flag procedure-relevant allergies:

• Latex: Use non-latex gloves, equipment
• Iodine/Betadine: Use chlorhexidine for skin prep
• Chlorhexidine: Use betadine for skin prep
• Lidocaine/local anesthetics: Use alternative anesthetic, allergy consult
• Adhesive/tape: Use alternative securement
• Heparin (HIT): Avoid heparin-coated catheters and flushes

Step 5: Check Anticoagulant Status

Tool: fhir_search
resourceType: "MedicationRequest"
queryParams: "patient=[patient-id]&status=active&category=http://terminology.hl7.org/CodeSystem/medicationrequest-category|inpatient"

Check active medications for anticoagulants and antiplatelets:

• Heparin drip: Check if held, last aPTT value
• Enoxaparin: Timing of last dose (hold 12h for prophylactic, 24h for therapeutic)
• Warfarin: Current INR
• DOACs (apixaban, rivarelbán, edoxaban): Timing of last dose (hold 24-48h)
• Clopidogrel, prasugrel, ticagrelor: Document if held
• Aspirin: Generally continued for most bedside procedures

Step 6: Check Consent Status

Tool: fhir_search
resourceType: "Consent"
queryParams: "patient=[patient-id]&status=active&scope=treatment"

If no procedure-specific consent found, flag: "INFORMED CONSENT: NOT DOCUMENTED -- obtain before proceeding."

Step 7: Pull Pre-Procedure Vitals

Tool: fhir_search
resourceType: "Observation"
queryParams: "patient=[patient-id]&category=vital-signs&_sort=-date&_count=10"

Document baseline vitals before procedure.

Troubleshooting

Pre-procedure labs are older than 24 hours

• Flag prominently: "Labs dated [date] -- [X] hours old. Consider recheck before procedure if clinically indicated."
• For INR and platelets, 24-48 hours is generally acceptable if no interval events (bleeding, transfusion, new anticoagulation).
• For hemoglobin in actively bleeding patients, recommend point-of-care testing.

Consent resource not found in FHIR

• Consent resources are not universally implemented in FHIR servers. Many systems store consent in paper or scanned documents.
• Search DocumentReference for scanned consent: fhir_search DocumentReference with patient=[id]&type=http://loinc.org|59284-0 (LOINC 59284-0 = Consent document).
• If not found, prominently flag: "INFORMED CONSENT STATUS: UNABLE TO VERIFY IN ELECTRONIC RECORD -- confirm paper consent before proceeding."

Procedure-specific CPT code not in standard list

• Use SNOMED CT coding as an alternative: system: "http://snomed.info/sct".
• Common SNOMED codes: 233573008 (central line), 52765003 (intubation), 277762005 (lumbar puncture), 86088003 (paracentesis), 91602002 (thoracentesis).
• If no standard code matches, use code.text with the procedure name as free text.
