Fever & possible sepsis: documentation that holds up

Sepsis is defined by organ dysfunction, not by hypotension — and hypotension is a late sign. The defensible chart shows the patient was screened for sepsis, documents the source hunt (and that you didn't anchor on a minor one), and records the timing of the bundle: lactate, cultures before antibiotics, antibiotics, fluids, and reassessment.

Critical pathway

Original, evidence-based synthesis — the critical diagnoses you cannot miss, the tests that catch them, and the interventions that can’t wait. Apply local protocol and judgment.

① Immediate
  • Full vitals with a perfusion assessment; obtain lactate and blood cultures, then start broad-spectrum antibiotics early for suspected sepsis.
  • Balanced-crystalloid resuscitation for hypotension or hyperlactatemia; identify and control the source.
② Critical tests
  • Lactate and blood cultures (before antibiotics when feasible)
  • CBC, renal/LFTs, urinalysis; chest imaging
  • Lumbar puncture when meningitis is suspected (do not delay antibiotics)
  • Imaging of any suspected deep/necrotizing source
③ Can’t-miss → act

Sepsis / septic shock

Trigger
Infection with hypotension or organ dysfunction
Test
Lactate, cultures, source imaging
Intervention
Early antibiotics, fluid resuscitation, vasopressors if fluid-refractory

Meningitis / encephalitis

Trigger
Headache, meningismus, or altered mentation
Test
Lumbar puncture
Intervention
Early empiric antibiotics ± acyclovir; dexamethasone where indicated

Necrotizing soft-tissue infection

Trigger
Pain out of proportion, crepitus, bullae, rapid spread
Test
Clinical; CT should not delay surgery
Intervention
Broad-spectrum antibiotics and emergent surgical debridement

Meningococcemia

Trigger
Petechial/purpuric rash with toxicity
Test
Clinical; cultures
Intervention
Immediate antibiotics and droplet precautions
④ Disposition

Septic or toxic-appearing patients are admitted (often to a monitored bed); a well-appearing patient with an identified minor source and reassuring vitals may be discharged with precautions.

01What's at stake

Late recognition is late treatment, and late treatment costs lives — every hour of hypotension before effective antibiotics raises mortality. The traps are believing a normotensive patient can't be septic, anchoring on a mildly positive urinalysis while a renal abscess or necrotizing infection festers, and never reassessing after the first liter. The chart that survives shows the organ-dysfunction reasoning and the clock.

02Can't-miss diagnoses

  • Septic shock — vasopressor need to keep MAP ≥65 plus lactate >2 despite fluids; hypotension is a late marker. → don't wait for it
  • The occult source — occult abdominal sepsis in the older or diabetic patient with minimal tenderness; fully undress the patient (the missed toe/sacral necrosis).
  • Necrotizing soft-tissue infection — pain out of proportion, crepitus → broad antibiotics + clindamycin and emergent surgery.
  • Meningitis — fever, headache, meningismus → empiric ceftriaxone + vancomycin (± ampicillin/acyclovir) without delay.
  • The immunocompromised / device-related / neutropenic fever — indwelling lines, hardware, recent chemo; culture the line and peripherally.

03Recognition & screening

  • Sepsis-3: infection + a rise in SOFA ≥2 (organ dysfunction). In the ED, look for hypoxia, altered mentation, hypotension/pressor need, rising creatinine, low platelets, hyperbilirubinemia, or lactate ≥2. → organ dysfunction
  • Don't rely on qSOFA alone — it is specific but insensitive (SSC 2021 recommends against it as a single screen); SIRS is neither necessary nor sufficient for sepsis.
  • Don't dismiss the EMR screening alert — institutional screens (NEWS, SIRS-based) catch occult sepsis; assess flagged patients quickly.
  • Beta-blockers/CCBs can mask tachycardia; the "well-appearing" patient can be early-septic.

Skip the typing

Work the case in the Fever / Possible Sepsis Workup — it records the qSOFA/organ-dysfunction screen, the lactate, and the source assessment, and assembles an MDM that documents the bundle timing and reassessment.

04Workup & bundle

  • Lactate — a perfusion marker; if >2, repeat to confirm clearance after resuscitation.
  • Blood cultures × 2 before antibiotics — but never let cultures delay antibiotics in the severely ill.
  • Antibiotics — early broad-spectrum IV; within 1 hour for probable sepsis/septic shock (a 3-hour window is acceptable only when infection is less likely and there's no shock); tailor to source, prior cultures, and resistance.
  • Fluids — 30 mL/kg balanced crystalloid for hypotension/hypoperfusion; individualize and document the rationale if giving less (e.g., severe CHF/ESRD), use ideal/adjusted body weight if BMI >30, and reassess with dynamic measures.
  • Vasopressors — norepinephrine first-line to MAP ≥65 (may start peripherally to avoid delay; dopamine not recommended); add vasopressin/hydrocortisone for refractory shock.
  • Source control — remove infected lines, consult surgery/IR promptly; don't anchor on a minor source.

05What to document

▼ weak
"Fever, looks well, normotensive. UTI. Ceftriaxone, discharged."
▲ defensible
"Fever 39.2, HR 112, BP 108/64, RR 24, SpO₂ 95%. Sepsis screen positive (organ dysfunction considered — lactate 2.6, otherwise no end-organ dysfunction); not relying on qSOFA alone. Source hunt: pyuria on UA, but fully examined skin/soft tissue/back/perineum (no necrotizing infection), abdomen benign, no meningismus, no indwelling devices — not anchoring on the UA. Blood cultures ×2 drawn, then IV antibiotics started [time]; 30 mL/kg balanced crystalloid given [time]. Reassessed after fluids: HR 96, BP 118/70, repeat lactate 1.4 (cleared), mentation normal. Admitted for sepsis with serial reassessment; return/escalation plan documented."

06Where charts fail

  • "Not hypotensive, so not septic" — missing organ dysfunction (sepsis is not defined by blood pressure).
  • Anchoring on a minor source (a mildly positive UA) and missing a renal abscess or necrotizing infection.
  • Not documenting bundle timing — lactate, cultures-before-antibiotics, antibiotic start, fluid volume/time.
  • Giving <30 mL/kg without documenting the specific concern for harm.
  • No reassessment after resuscitation (lactate clearance, perfusion, mentation), or not undressing the patient.
