Management of pulmonary embolism, in a patient with egfr 43, weught 116kg. i have attached UHB trust guidelines and also look at bmj best practise or nice guideline, management plan for suitabel anticaogulation

"pulmonary embolism" AND anticoagulation AND "renal impairment"
| Haemodynamically STABLE | Haemodynamically UNSTABLE | |
|---|---|---|
| Definition | None of the criteria below | Cardiac arrest, obstructive shock (SBP <90 for >15 min + signs of hypoperfusion), or persistent hypotension |
| Next step | Standard anticoagulation (below) | Systemic thrombolysis ± escalation (Figure 2, UHB guideline) |
| Criterion | Score |
|---|---|
| Age >80 years | +1 |
| Cancer (active) | +1 |
| Chronic cardiopulmonary disease | +1 |
| HR ≥110 bpm | +1 |
| SBP ≤100 mmHg | +1 |
| SpO2 <90% | +1 |
Apixaban 10 mg twice daily for 7 days, then 5 mg twice daily
| Indication | Dose for 116 kg |
|---|---|
| Inpatient treatment (BD) | Enoxaparin 1 mg/kg BD = 116 mg BD (prescribe as 120 mg BD - round to nearest 20 mg syringe) |
| Outpatient/discharge (OD) | Enoxaparin 1.5 mg/kg OD = 174 mg OD (prescribe 180 mg OD) |
| PE type | Minimum duration |
|---|---|
| Provoked (identifiable transient risk factor) | 3 months |
| Unprovoked | 3 months minimum; extended therapy discussion at thrombosis clinic |
| Cancer-associated | LMWH or DOAC - see CAT guideline |
| Decision point | Recommendation |
|---|---|
| Anticoagulant of choice | Apixaban (first line per UHB + NICE NG158) |
| Loading dose | 10 mg twice daily x 7 days |
| Maintenance dose | 5 mg twice daily (no dose reduction - weight 116 kg means weight criterion not met) |
| If LMWH needed | Enoxaparin 120 mg BD (1 mg/kg BD, rounded) with anti-Xa monitoring (4h post-dose; target 0.6-1.0 IU/mL) |
| Outpatient suitability | CrCl >15 ml/min, so renal function alone does NOT exclude outpatient management - assess sPESI + clinical criteria |
| Duration | Minimum 3 months; review at thrombosis clinic |
| Rivaroxaban | Acceptable alternative; avoid if CrCl <15 ml/min |
| Warfarin | Less preferred; requires bridging LMWH; use if DOAC not tolerated |
| Cancer-associated PE | LMWH or DOAC per CAT guideline |
⚠ Clinical note: The actual serum creatinine should be checked to complete the apixaban dose-reduction scoring (criterion: Cr ≥133 µmol/L). At eGFR 43, it is likely to be elevated, but since the weight criterion (≤60 kg) is definitively not met at 116 kg, the patient cannot meet the 2-of-3 threshold regardless - so standard dosing (10 mg BD then 5 mg BD) applies with confidence.Anti-Xa monitoring for LMWH is strongly recommended given weight >100 kg AND eGFR 43 - this combination increases accumulation risk. If LMWH is chosen over a DOAC, tinzaparin may be preferable to enoxaparin at this level of renal function.

| Criterion | Score |
|---|---|
| Age >80 years | +1 |
| Active cancer | +1 |
| Chronic cardiopulmonary disease | +1 |
| HR ≥110 bpm | +1 |
| SBP ≤100 mmHg | +1 |
| SpO2 <90% | +1 |
| Parameter | This patient | Threshold | Action |
|---|---|---|---|
| eGFR | 43 ml/min/1.73m² | >15 = safe for apixaban | ✅ Apixaban appropriate |
| Weight | 116 kg | ≤60 kg = dose-reduction criterion | ❌ NOT met — no weight-based reduction |
| Age | (unknown - check) | ≥80 = dose-reduction criterion | Check chart |
| Serum creatinine | Check actual value | ≥133 µmol/L = criterion | Likely met at eGFR 43 |
At 116 kg, the weight criterion is definitively not met, so the patient cannot score 2 of 3 regardless of age or creatinine. Standard VTE treatment dose applies.
Apixaban 10 mg TWICE DAILY for 7 days (days 1-7)thenApixaban 5 mg TWICE DAILY (day 8 onwards, minimum 3 months)
| Exclusion criterion | Check |
|---|---|
| HR >110 or SBP <100 | Must be absent |
| Syncope/pre-syncope | Must be absent |
| SpO2 <94% or oxygen requirement | Must be absent |
| Active bleeding / high bleeding risk | Must be absent |
| RV dysfunction (ECG, troponin, NT-proBNP, echo) | Must be absent |
| CrCl <15 ml/min | ✅ eGFR 43 → CrCl well above 15 — NOT excluded on renal grounds |
| Severe liver disease | Must be absent |
| On full-dose anticoagulation at time of PE | Must be absent |
| Other comorbidities needing admission | Must be absent |
| Social barriers (lives alone, no phone, frailty) | Must be absent |
⚠ Key point: eGFR 43 (CKD stage 3b) does NOT by itself exclude outpatient management. The UHB threshold is CrCl <15 ml/min. This patient is well above it.
| PE type | Duration |
|---|---|
| Provoked (surgery, immobility, trauma) | 3 months then stop |
| Unprovoked (no clear cause) | Minimum 3 months — extended therapy discussion at thrombosis clinic |
| Cancer-associated | Ongoing — see CAT guideline |
| Step | Action |
|---|---|
| 1 | Haemodynamic assessment → stabilise → bloods + ECG + CXR |
| 2 | CTPA to confirm PE → sPESI risk score → interim apixaban 10 mg BD if delay |
| 3 | Apixaban 10 mg BD x 7 days then 5 mg BD — standard dose confirmed (116 kg fails weight criterion, cannot score 2/3 for reduction) |
| 4 | sPESI 0 + no exclusions → outpatient; sPESI ≥1 → admit. eGFR 43 alone does NOT bar outpatient management |
| 5 | Min 3 months treatment; thrombosis clinic referral; renal monitoring at 1 month; GP informed |
