Infusion rate: [mL/hr]

IV access site and concurrent fluids: [Access type/site; concurrent IV fluids and rates]

(If multiple units transfused, identify which unit was infusing at symptom onset.)

• Key symptoms: [Document presence or absence of: fever/chills/rigors, rash/urticaria/pruritus/angioedema, dyspnea/hypoxemia/wheezing/stridor, chest/back/flank pain, hypotension or hypertension, tachycardia, dark urine/hemoglobinuria, nausea/vomiting]

Vital Signs

(If values unavailable, document as "not documented.")

• Pre-transfusion baseline [time]: T [temp], HR [rate], BP [value], RR [rate], SpO2 [value] on [oxygen delivery]
• At symptom recognition [time]: T [temp], HR [rate], BP [value], RR [rate], SpO2 [value] on [oxygen delivery]
• After stopping transfusion [time]: T [temp], HR [rate], BP [value], RR [rate], SpO2 [value] on [oxygen delivery]
• Reassessment [time]: T [temp], HR [rate], BP [value], RR [rate], SpO2 [value] on [oxygen delivery]
• At resolution/disposition [time]: T [temp], HR [rate], BP [value], RR [rate], SpO2 [value] on [oxygen delivery]

Physical Examination

• General/mental status: [Appearance, level of distress, orientation]
• Skin: [Rash/urticaria/flushing present or absent; distribution/extent; angioedema location if present]
• HEENT: [Lip/tongue/uvular edema; voice changes; airway patency]
• Lungs: [Work of breathing; wheezes; crackles; accessory muscle use]
• Cardiovascular: [Heart sounds; JVP if assessed; edema; perfusion; S3 if present]
• Abdomen/Flanks: [Tenderness; other pertinent findings]
• Urine: [Color/appearance; hemoglobinuria suspected yes/no]

Immediate Actions

• Transfusion stopped: [Time]
• IV management: [Line maintained; new tubing if indicated]
• Supportive measures: [Interventions with times and doses: oxygen, IV fluids, diuretics, antihistamines, corticosteroids, bronchodilators, epinephrine, vasopressors, antipyretics as applicable] (If no interventions required, state symptoms resolved spontaneously with observation.)
• Bedside clerical check: [Performed; patient ID vs unit tag match/mismatch]
• Product inspection: [Visual appearance of unit and tubing]
• Unit disposition: [Returned to blood bank per protocol at (time)]
• Notifications: [Blood bank, primary team, others notified with times]

Diagnostic Workup

Assessment

Severity: [non-severe / severe / life-threatening] — Basis: [hemodynamic instability / respiratory failure / ICU transfer / other]

Differential Diagnosis: (For each relevant reaction type, note supporting features, features against, and key pending tests.)

• Allergic/Anaphylaxis: [Supporting]; [Against]; [Pending tests]. (Note skin-limited vs systemic involvement; epinephrine use and response if applicable.)
• Febrile Non-Hemolytic (FNHTR): [Supporting]; [Against]; [Pending tests]. (Acknowledge hemolysis and sepsis being excluded.)
• TRALI: [Supporting]; [Against]; [Pending tests]. (Note pre-transfusion respiratory status and alternative ARDS risk factors.)
• TACO: [Supporting]; [Against]; [Pending tests]. (Include transfusion rate, fluid balance, response to diuresis.)
• Acute Hemolytic (AHTR): [Supporting]; [Against]; [Pending tests]. (Note clerical check result and DAT status.)
• Other considerations: [Bacterial contamination/sepsis, underlying hemorrhage, medication reaction, PE, other]

Working Diagnosis: [Most likely diagnosis] — Classification status: [Provisional pending blood bank evaluation / Final per blood bank report]

Plan

Immediate Management: [Monitoring plan (vital sign frequency, respiratory monitoring, urine output); ongoing supportive care; escalation thresholds]

Transfusion Plan: [Additional transfusion needed: yes/no] [Transfusion will continue/restart / will not be restarted] (If restarting: specify authorization, required conditions, rate modifications, monitoring plan.)

Future Transfusion Precautions: [Reaction flag added to chart]; [Allergy/adverse reaction list updated]; [Recommended product modifications: washed / slower rate / pre-emptive diuresis / other]; [Hematology/transfusion medicine follow-up if needed]
