Transplant patient complication
A streamlined, differential-led presentation for rapid clinical review.
Twenty-second review
- Transplant patients are vulnerable to infection, rejection, medication toxicity, thrombosis, and organ-specific failure because of altered immunity and complex therapy.
- Fever, graft-region pain, reduced organ function, dyspnea, shock, new neurologic change, or missed immunosuppression requires urgent specialist assessment.
- Keep unrelated common illness in the differential; overlapping or concurrent illness remains possible.
- For transplant patient complication, trends and combinations of findings are more informative than one isolated vital sign.
Compare the clinical patterns
The repeated material is grouped inside each possibility. Open only the condition you need.
RejectionTime-sensitive high-risk possibility
HPI
Clarify transplant type and date; presenting symptom and onset; anti-rejection medications.
Signs & symptoms
Organ-specific dysfunction, pain, fever, or systemic compromise.
Focused exam
Perform a targeted cardiorespiratory, neurologic, abdominal, skin, and hydration assessment guided by the history; Assess function against baseline rather than relying on a single normal-looking measurement.
Brief pathophysiology
Rejection may cause transplant patient complication through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
General medical differentials have overlapping physiology. These four observations screen for deterioration and common reversible causes without implying a diagnosis.
Respiratory rate (breaths/min)
Trend rate / effortRespiratory rate can reveal early physiologic stress.
Blood pressure (mmHg)
Compare with baselineRelative hypotension may be important before an absolute threshold is crossed.
Heart rate (bpm)
Trend rate / rhythmInterpret with hydration, perfusion, medications, and symptoms.
Blood glucose (mmol/L)
Check when indicatedGlucose disturbance can cause weakness or altered mentation.
Front-load in the triage report
- Rejection: Organ-specific dysfunction, pain, fever, or systemic compromise.
- Transplant type and date?
- Presenting symptom and onset?
Opportunistic infectionTime-sensitive high-risk possibility
HPI
Clarify presenting symptom and onset; anti-rejection medications; fever or infection symptoms.
Signs & symptoms
Organ-specific dysfunction, pain, fever, or systemic compromise.
Focused exam
Assess function against baseline rather than relying on a single normal-looking measurement; Identify organ and date, transplant centre, medications and adherence, recent labs or procedures, infection exposure, graft-region findings, and device sites.
Brief pathophysiology
Opportunistic infection may cause transplant patient complication through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
No single vital sign diagnoses sepsis. New tachypnea, abnormal temperature, tachycardia, or falling pressure—especially with altered mentation or poor perfusion—supports organ dysfunction and urgency.
Respiratory rate (breaths/min)
May rise earlyTachypnea is included in NEWS2 and can precede overt hypotension.
Temperature (°C)
High or lowAbsence of fever does not exclude sepsis; hypothermia is concerning.
Heart rate (bpm)
Often risesTachycardia is common but may be blunted by age or medication.
Blood pressure (mmHg)
May fallRelative hypotension and trend matter; profound hypotension can be late.

- Opportunistic infection: Organ-specific dysfunction, pain, fever, or systemic compromise.

Common infectionCommon presentation pattern
HPI
Clarify transplant type and date; presenting symptom and onset; anti-rejection medications.
Signs & symptoms
Immunosuppression changes presentation and drug clearance.
Focused exam
Perform a targeted cardiorespiratory, neurologic, abdominal, skin, and hydration assessment guided by the history; Assess function against baseline rather than relying on a single normal-looking measurement.
Brief pathophysiology
Common infection may explain the presenting symptoms through a common clinical mechanism, while serial assessment checks for complications or an alternate cause.
