CCS Integrated Cases
CCS case: pediatric fever with petechial rash
— Fever + petechial/purpuric rash in a child is invasive meningococcal disease (IMD) until proven otherwise — Neisseria meningitidis septicemia ± meningitis carries 10–15% mortality even with optimal care, and progression from well-appearing to shock can occur in <12 hours
— Other invasive bacterial causes: Streptococcus pneumoniae, group A strep, H. influenzae type b (unvaccinated/under-immunized), Staphylococcus aureus (especially with endocarditis)
— Infants 3–12 months and adolescents 16–23 years (dormitory, military recruits) are peak-incidence groups for meningococcus
— Asplenia (functional in sickle cell, surgical), terminal complement deficiency (C5–C9), eculizumab therapy, properdin deficiency → recurrent or fulminant Neisseria infections
— Recent travel to the African "meningitis belt" or Hajj pilgrimage; close contact in childcare, school, or household with confirmed case
— Incomplete MenACWY or MenB vaccination history
— Fever ≥38.5°C plus any non-blanching rash (petechiae below the nipple line, purpura, ecchymosis) — even one petechia + fever + ill appearance warrants full workup
— Leg pain, cold hands/feet, abnormal skin color (mottled, pale, cyanotic) are early septic shock signs in children, often preceding hypotension by hours
— Altered mental status, poor feeding in infants, bulging fontanelle, neck stiffness
— Tests recognition speed, empiric antibiotic timing (<1 hour), fluid resuscitation thresholds, chemoprophylaxis of contacts, and disposition (ICU vs floor)
CCS pearl: On the CCS case, the first three orders before any test result returns should be IV access × 2, blood cultures, and ceftriaxone IV — do not wait for the LP. The clock punishes delay in antibiotics far more than it punishes a missing LP result.
— Previously healthy 4-year-old (or 17-year-old college freshman) brought to the ED with 12–24 hours of fever, headache, vomiting, and a rash that "started on the legs and spread." Parents noticed the spots do not blanch when pressed with a glass
— Adolescent variant: dormitory resident with sudden fever, myalgias mistaken for influenza, then rapid appearance of purpuric lesions
— Timeline of rash: petechiae appearing and spreading within hours → high-risk for meningococcemia; slowly evolving rash over days favors viral
— Fever pattern: height, duration, response to antipyretics
— Associated symptoms: headache, photophobia, neck stiffness, vomiting, leg pain, cold extremities, decreased urine output
— Vaccination status: MenACWY (11–12 y, booster 16 y), MenB (16–23 y shared decision), Hib, PCV, varicella
— Exposures: sick contacts, daycare/school outbreaks, recent URI, tick exposure, travel, animal exposure
— Past medical history: sickle cell disease, asplenia, complement deficiency, immunosuppression, prior invasive bacterial infection
— Medications: recent antibiotics (may partially treat and mask), NSAIDs (can cause petechiae from platelet dysfunction)
— Petechiae above the nipple line only → often Valsalva (cough, vomiting) — lower risk
— Petechiae below the nipple line, or generalized, or purpuric → invasive bacterial disease until excluded
— Rapidly spreading rash, ill appearance, mottling, capillary refill >3 sec
Board pearl: The combination of fever + petechiae + ill appearance has a positive predictive value for serious bacterial infection of ~15–20%, but the cost of missing meningococcemia is catastrophic — empiric treatment is the standard even when probability is modest.
Key distinction: Viral exanthems (enterovirus, EBV, CMV) can cause petechiae but the child typically appears well between fever spikes with normal perfusion and no toxic appearance.
— Use Pediatric Assessment Triangle: appearance (tone, interactiveness, consolability, look/gaze, speech), work of breathing, circulation to skin
— "Toxic" child: lethargic, poorly responsive, weak cry, poor eye contact → activate sepsis pathway immediately
— Tachycardia out of proportion to fever (HR persistently elevated after antipyretic + fluid bolus) is an early shock marker
— Hypotension is a LATE finding in pediatric shock — children compensate with tachycardia and vasoconstriction; SBP <70 + (2 × age in years) defines hypotension
— Tachypnea, narrow pulse pressure (<25 mmHg), prolonged capillary refill (>3 sec)
— Temperature instability — hypothermia in young infants is as concerning as fever
— Petechiae: pinpoint (1–2 mm), non-blanching, often on dependent areas, palate, conjunctivae
— Purpura: >3 mm, non-blanching
— Purpura fulminans: confluent retiform purpura with central necrosis — pathognomonic for fulminant meningococcemia/DIC
— Glass/tumbler test: pressure does not blanch the lesion
— Mottling score, cold/warm line on extremities (peripheral vasoconstriction)
— Mental status (AVPU or GCS), Kernig/Brudzinski (often absent in infants and young children), bulging fontanelle in infants, focal deficits, seizures
— Photophobia, neck stiffness
— Joint exam (septic arthritis can coexist), HEENT (otitis, pharyngitis source), abdomen (splenomegaly suggests EBV/leukemia DDx)
Step 3 management: If capillary refill >3 sec, mottling, altered mental status, or hypotension is present → the child is in septic shock and the order set is simultaneous antibiotics + 20 mL/kg isotonic crystalloid bolus + ICU consult, regardless of pending labs.
— Two large-bore IVs (or IO if access fails after 90 sec in shock)
— CBC with differential — leukocytosis with left shift or leukopenia (worse prognosis), thrombocytopenia (DIC)
— CMP — hyponatremia (SIADH/sepsis), AKI, transaminitis
— Blood culture × 2 before antibiotics if it does not delay them >45 min
— Coagulation studies: PT/INR, aPTT, fibrinogen, D-dimer — looking for DIC (prolonged PT/aPTT, low fibrinogen, high D-dimer, low platelets)
— Lactate, venous blood gas — lactate >4 or persistent >2 after fluids suggests shock
— CRP and procalcitonin — procalcitonin >2 ng/mL supports bacterial; elevated CRP nonspecific
— Urinalysis and urine culture — rule out alternative source
— Type and screen — anticipate transfusion in DIC/purpura fulminans
— Glucose, calcium, magnesium — frequent abnormalities in septic children
— Indicated if signs of meningitis or no clear alternative source — but do not delay antibiotics
— Contraindications/defer LP: hemodynamic instability, coagulopathy/thrombocytopenia <50k, focal neuro deficit, signs of increased ICP, skin infection over site
— CSF studies: cell count + diff, glucose (paired serum), protein, Gram stain, culture, bacterial PCR (meningococcal/pneumococcal), opening pressure if able
— Bacterial CSF pattern: neutrophilic pleocytosis (>1000), glucose <40 (or CSF:serum <0.4), protein >200
— Head CT before LP only if focal deficit, papilledema, recent seizure, immunocompromise, or altered mental status — do not routinely delay LP for CT in children
— CXR if respiratory symptoms
CCS pearl: On the simulated case, advance the clock in 15–30 minute increments during the first 2 hours. Reassess vitals, perfusion, mental status, and urine output (place a Foley if in shock) after each intervention.
— Blood culture: gold standard but may take 24–48 h; yield reduced if pre-treated with antibiotics
— CSF Gram stain: gram-negative diplococci → meningococcus; gram-positive diplococci → pneumococcus; gram-positive cocci in clusters → staph; gram-negative coccobacilli → Hib
— CSF and blood PCR for N. meningitidis (ctrA gene), S. pneumoniae, H. influenzae — high sensitivity even after antibiotics begun
— Skin lesion aspirate or scraping Gram stain — can show diplococci in meningococcemia (often forgotten)
— Serogrouping (B, C, Y, W-135, A) for public health and post-discharge vaccine counseling
— Rickettsial PCR/serology and empiric doxycycline if tick exposure or travel to RMSF-endemic area — do not wait for confirmation
— EBV/CMV serology, enterovirus PCR
— ANA, complement (C3, C4, CH50), platelet antibodies if HSP/ITP suspected
— Peripheral smear if leukemia on differential — blasts, schistocytes (HUS, TTP), atypical lymphocytes
— Stool studies + ADAMTS13 if HUS/TTP considerations
— Echocardiogram if persistent fever, new murmur, septic emboli suspected → endocarditis
— Joint ultrasound or MRI for septic arthritis/osteomyelitis if focal pain
— Bilateral adrenal ultrasound/CT if refractory shock — Waterhouse-Friderichsen syndrome (bilateral adrenal hemorrhage in meningococcemia)
— Total complement (CH50), terminal complement components (C5–C9), properdin in recurrent or unusual Neisseria infection
— Splenic function assessment (Howell-Jolly bodies on smear) if asplenia suspected
Board pearl: A child who survives meningococcal disease should have complement screening before discharge planning if there's any feature suggesting immunodeficiency (recurrent neisserial infection, family history, unusual serogroup).
— Well-appearing, isolated petechiae above nipple line, normal vitals: lower risk — observation, CBC/CRP, blood culture, consider discharge with strict return precautions and 24-h follow-up
— Fever + petechiae + any ill appearance, abnormal vitals, or purpura: high risk — full sepsis workup, empiric IV antibiotics, admit
— Septic shock (mottling, cap refill >3 sec, altered mental status, hypotension): PICU, fluid resuscitation, vasopressors
— 0–15 min: Recognize, IV/IO access, blood culture, point-of-care glucose, lactate
— 0–60 min: Empiric antibiotics within 1 hour, isotonic crystalloid bolus 10–20 mL/kg over 5–20 min, repeat boluses up to 40–60 mL/kg titrated to perfusion (watch for hepatomegaly, rales — signs of fluid overload)
— Reassess after each bolus: HR, BP, cap refill, mental status, urine output (goal >1 mL/kg/h)
— If fluid-refractory shock after 40–60 mL/kg → start vasoactive infusion (epinephrine for cold shock, norepinephrine for warm shock) via peripheral IV or IO until central access; do NOT delay vasopressors waiting for central line
— Consider stress-dose hydrocortisone 2 mg/kg IV in catecholamine-resistant shock or if Waterhouse-Friderichsen suspected
— Shock, altered mental status, respiratory failure, DIC, purpura fulminans → PICU
— Stable but ill-appearing, requires monitoring and IV antibiotics → pediatric ward with telemetry/continuous monitoring
— True low-risk → consider observation unit with serial exams over 4–6 hours
CCS pearl: On the CCS clock, the sequence is: Order antibiotics → order fluid bolus → reassess at 15 min → reassess at 1 hour. If you forget to advance the clock and reassess, you lose management points even if your orders are correct.
— Ceftriaxone 100 mg/kg IV (max 4 g) once daily, or 50 mg/kg IV q12h for meningitis dosing — covers meningococcus, pneumococcus, Hib, most gram-negatives
— Add vancomycin 15 mg/kg IV q6h (target trough 15–20 if meningitis) for ceftriaxone-resistant pneumococcus coverage when meningitis is in the differential
— Infants <1 month: ampicillin + cefotaxime (or ceftriaxone with caution re: bilirubin displacement and Ca-containing fluids) + acyclovir if HSV considered; add gentamicin for synergy
— Infants 1–3 months: ampicillin + ceftriaxone ± vancomycin
— Doxycycline 2.2 mg/kg IV/PO q12h (max 100 mg/dose) if Rocky Mountain spotted fever possible — do not withhold in children regardless of age; benefit outweighs minor tooth staining risk in short courses
— Acyclovir 20 mg/kg IV q8h in neonates and young infants with possible HSV
— Clindamycin if toxic shock syndrome suspected (toxin suppression)
— Antipseudomonal coverage (cefepime, piperacillin-tazobactam) in immunocompromised or nosocomial settings
— Dexamethasone 0.15 mg/kg IV q6h × 4 days for suspected/proven Hib or pneumococcal meningitis — give before or with first antibiotic dose; reduces hearing loss in Hib
— Not clearly beneficial in meningococcal meningitis but may be started empirically before pathogen identification
— Meningococcemia/meningitis: 5–7 days IV ceftriaxone
— Pneumococcal meningitis: 10–14 days; Hib meningitis: 7–10 days
— Group B strep meningitis (infants): 14–21 days
Step 3 management: Antibiotics first, LP second if there's any delay. A negative culture from CSF after pre-treatment does not change the clinical decision to treat empirically for the full course.
— Who qualifies as "close contact": household members, childcare/preschool contacts, anyone with direct exposure to oral secretions (kissing, shared utensils, mouth-to-mouth resuscitation, intubation without PPE) in the 7 days before symptom onset
— Casual contacts (classmates without close interaction, healthcare workers with PPE) do NOT need prophylaxis
— Regimens (give within 24 hours ideally, up to 14 days post-exposure):
— Rifampin 10 mg/kg PO q12h × 2 days (5 mg/kg if <1 month) — turns secretions orange, reduces OCP efficacy
— Ciprofloxacin 500 mg PO × 1 (adults/adolescents ≥1 month per updated CDC guidance)
— Ceftriaxone 125 mg IM × 1 (<15 y) or 250 mg IM × 1 (≥15 y) — preferred in pregnancy
— Notify the local health department — mandatory reportable disease
— Isolation: droplet precautions for first 24 hours of effective antibiotics
— Foley catheter for strict I/O monitoring in shock
— Correct electrolytes: hypoglycemia (D10 2 mL/kg bolus), hypocalcemia (especially in massive transfusion), hyponatremia (cautious correction)
— Transfusion thresholds in DIC/purpura fulminans:
— FFP if active bleeding + PT/aPTT prolonged
— Cryoprecipitate if fibrinogen <100 mg/dL
— Platelets if <20k, or <50k with bleeding/procedure
— pRBC to maintain Hgb >7 (>10 if active bleeding/shock)
— Vasopressors via central or IO until central line; arterial line for continuous BP
— Mechanical ventilation for respiratory failure or airway protection
— CRRT for AKI with fluid overload or refractory acidosis
— Surgical debridement/amputation for purpura fulminans necrosis (later)
— Consider protein C concentrate in research/specialty centers for purpura fulminans
CCS pearl: Place "public health notification" and "chemoprophylaxis for household contacts" as explicit orders — these are scored.
— Incidence 25–50% in septic shock; defined by KDIGO pediatric criteria (pRIFLE)
— Causes: hypoperfusion (most common), DIC microthrombi, drug nephrotoxicity (aminoglycosides, vancomycin), pigmenturia from rhabdomyolysis, HUS in differential
— Adjust antibiotic dosing:
— Ceftriaxone: no renal adjustment (hepatic clearance) — preferred in AKI
— Vancomycin: extend interval, monitor levels (AUC-guided dosing preferred over trough alone)
— Acyclovir: reduce dose, ensure hydration to prevent crystal nephropathy
— Avoid nephrotoxins: NSAIDs, contrast if possible, aminoglycosides if alternative exists
— Consider early nephrology consult if Cr doubles, oliguria persists despite fluids, or electrolyte derangements (hyperkalemia, severe acidosis)
— Sepsis-induced transaminitis and cholestasis are common; usually resolve with source control
— Severe hepatic dysfunction (INR >1.5 without DIC, encephalopathy) → consider co-existing process: hemophagocytic lymphohistiocytosis (HLH), Reye-like syndromes, drug-induced injury
— Acetaminophen dosing: maximum 75 mg/kg/day in children; reduce if hepatic dysfunction
— Avoid hepatotoxins; review every medication for hepatic metabolism
— Balanced crystalloids (LR, Plasma-Lyte) are preferred over normal saline in resuscitation to reduce hyperchloremic acidosis and AKI risk (pediatric trial data emerging, adult SMART/SALT-ED supportive)
— Avoid hyperchloremia; monitor chloride trends
— Avoid synthetic colloids (hydroxyethyl starch) — increase AKI
— Switch to adult dosing typically at ~40 kg or per institutional protocol
— Confirm renal/hepatic function before adult ceftriaxone dosing (2 g IV q12h for meningitis)
Key distinction: Ceftriaxone is the workhorse precisely because it requires no renal dosing adjustment — even with AKI, the standard meningitis dose is unchanged. Vancomycin is what you adjust.
— Pathogens shift: Group B Streptococcus, E. coli, Listeria monocytogenes, HSV, enterovirus dominate
— Empiric regimen: ampicillin + cefotaxime (or gentamicin) + acyclovir
— Fever ≥38°C in <28 d → full sepsis workup including LP and admission for IV antibiotics, no exceptions
— 29–60 days: risk-stratify with Rochester/PECARN/Step-by-Step criteria; most still admitted
— Encapsulated organisms (pneumococcus, meningococcus, Hib, Salmonella) cause overwhelming sepsis
— Daily penicillin prophylaxis until age 5 (continue longer if prior pneumococcal sepsis or surgical splenectomy)
— Ensure PCV13/PCV15/PCV20, PPSV23, MenACWY, MenB, Hib vaccines current
— Any fever ≥38.5°C → ED, blood culture, ceftriaxone IV/IM even if well-appearing
— Terminal complement (C5–C9), properdin, factor H/I deficiency → recurrent Neisseria infection with milder serogroups
— Eculizumab/ravulizumab (used in PNH, atypical HUS, myasthenia) → 1000–2000× increased meningococcal risk → mandatory MenACWY + MenB before therapy and prophylactic penicillin
— Screen with CH50 (classic), AH50 (alternative pathway)
— Oncology patients with fever + neutropenia + petechiae → broaden to cefepime or pip-tazo + vancomycin, consider antifungals
— HIV: depending on CD4, broaden coverage and consider opportunistic pathogens
— Asplenia (surgical, sickle cell, congenital): same as above, plus emergency antibiotic kit at home
— Dormitory/college residents — MenACWY required for many universities; MenB is shared clinical decision-making (16–23 y)
— Consider sexual history, pregnancy testing in females, substance use
Board pearl: A child on eculizumab with fever and any petechiae is meningococcemia until proven otherwise — admit, culture, treat empirically, every single time, regardless of vaccine status.
— Septic shock with multiorgan dysfunction — leading cause of death
— DIC and purpura fulminans — microthrombi → skin necrosis, digit/limb loss requiring amputation, organ infarction
— Waterhouse-Friderichsen syndrome — bilateral adrenal hemorrhage → refractory hypotension despite vasopressors; suspect when shock doesn't respond → empiric hydrocortisone
— Acute respiratory distress syndrome (ARDS) — bilateral infiltrates, P/F <300
— Acute kidney injury — may require CRRT
— Disseminated intravascular coagulopathy with bleeding (GI, CNS, mucosal)
— Cerebral edema, herniation in meningitis — watch for Cushing triad, pupillary changes
— Seizures (15–30% of bacterial meningitis) — load with levetiracetam or fosphenytoin
— Subdural empyema, ventriculitis, hydrocephalus — neurosurgical complications
— Septic arthritis, osteomyelitis, pericarditis, endophthalmitis — metastatic seeding
— Sensorineural hearing loss — up to 30% of bacterial meningitis survivors; mandatory audiology evaluation before discharge and again at 1 month
— Neurodevelopmental sequelae: cognitive delay, learning disability, behavioral changes, motor deficits, epilepsy
— Skin scarring and amputations from purpura fulminans — multidisciplinary rehab, prosthetics, plastic surgery
— Reactive arthritis, pericarditis, vasculitis 4–10 days into illness (immune-complex mediated) — usually self-limited, NSAIDs
— Hypotension on arrival, low WBC (<5k) or platelet count (<100k), absent meningitis features (pure septicemia worse than meningitis alone), DIC, age <1 or >50, lactate >4, GCS <8
CCS pearl: Order a formal audiology evaluation before discharge for any child with bacterial meningitis — missing this is a scored omission and a real-world quality measure.
— Septic shock requiring vasoactive infusion
— Respiratory failure or need for mechanical ventilation
— Altered mental status (GCS ≤12), seizures, focal deficits
— DIC with active bleeding, purpura fulminans
— Multi-organ dysfunction (AKI requiring CRRT, hepatic failure, ARDS)
— Persistent lactate >4 or worsening despite resuscitation
— Age <3 months with confirmed bacterial sepsis/meningitis
— Pediatric intensive care — primary admitting in shock
— Pediatric infectious disease — pathogen identification, duration, prophylaxis, immunologic workup
— Pediatric neurology — for seizures, encephalopathy, neurodevelopmental follow-up
— Audiology — pre-discharge in meningitis
— Plastic surgery / orthopedics — purpura fulminans with tissue necrosis
— Nephrology — AKI needing CRRT
— Hematology — refractory DIC, transfusion strategy
— Public health / hospital epidemiology — contact tracing, chemoprophylaxis
— Child life and social work — family support, post-discharge resource planning
— Community hospital without PICU → stabilize and transfer; do not delay antibiotics waiting for transport
— Pre-transfer checklist: secure airway if borderline, two IVs, antibiotics started, fluids running, vasopressors via IO/peripheral if needed, blood products available, transport team briefed
— Document pre-transfer vitals, last antibiotic dose, fluid totals, urine output
— Update family at every transition; involve them in decisions
— Code status discussion if multi-organ failure progressing
— Ethics consult if disagreement about goals of care
Step 3 management: A community ED physician faced with suspected meningococcemia should give ceftriaxone IM/IV in the ED before arranging transfer — pre-transfer antibiotics improve survival; "transferring without treating" is a Step 3 trap.
— Fever, headache, myalgias, then rash starting on wrists/ankles → palms/soles → centripetal spread; petechial by day 5
— Exposure: tick bite in southeastern/south central US (April–September)
— Labs: thrombocytopenia, hyponatremia, transaminitis
— Empiric doxycycline 2.2 mg/kg q12h in all ages — do not wait for serology
— Ehrlichiosis, anaplasmosis (similar empiric doxycycline)
— Dengue (travel, hemorrhagic features), chikungunya
— Leptospirosis (water exposure, conjunctival suffusion)
— Enterovirus/echovirus — common cause of fever + petechial rash in children, especially summer/fall; usually well-appearing
— EBV/CMV — atypical lymphocytes, hepatosplenomegaly, may have petechiae especially on palate
— Parvovirus B19 — "gloves and socks" syndrome, petechial acral distribution
— Measles — Koplik spots, cephalocaudal morbilliform rash, conjunctivitis, coryza
— Hemorrhagic fevers — travel history (Ebola, Lassa, hantavirus, severe dengue)
— Pneumococcal sepsis — especially asplenia
— Group A strep / scarlet fever / TSS — sandpaper rash, strawberry tongue, desquamation
— Staphylococcal TSS — tampon use, surgical wound, hypotension, diffuse erythroderma
— Capnocytophaga canimorsus — dog bite, asplenic patient, fulminant sepsis
— Endocarditis with septic emboli — Janeway lesions, Osler nodes, splinter hemorrhages
— Rare causes of petechiae in immunocompromised hosts
Key distinction: Meningococcemia spreads centrifugally and rapidly with purpura; RMSF spreads centripetally from wrists/ankles; enteroviral petechiae appear in a well-looking child with normal vitals.
— Acute leukemia (ALL, AML) — fever (often from neutropenia or leukemic infiltration), bruising, petechiae, hepatosplenomegaly, bone pain, pallor; CBC shows blasts, cytopenia, or hyperleukocytosis; peripheral smear is key
— Immune thrombocytopenic purpura (ITP) — well child, often post-viral, isolated petechiae/purpura, isolated thrombocytopenia with otherwise normal CBC; child looks well
— Aplastic anemia — pancytopenia, no organomegaly
— TTP/HUS — MAHA, thrombocytopenia, AKI; HUS often after E. coli O157:H7 diarrhea
— Henoch-Schönlein purpura (IgA vasculitis) — palpable purpura on buttocks and lower extremities, arthritis/arthralgia, abdominal pain, hematuria/proteinuria; child generally well, afebrile or low-grade fever
— Kawasaki disease — typically maculopapular not petechial, but consider in prolonged fever ≥5 days with conjunctivitis, mucositis, extremity changes, lymphadenopathy, rash
— Systemic JIA, SLE — chronic fever, multi-system
— Valsalva petechiae — face/neck only, after vomiting, coughing, crying, strangulation
— Non-accidental trauma — petechiae in unusual distribution (neck = strangulation), bruising of varying ages, inconsistent history → mandatory reporting
— Tourniquet effect from tight clothing
— Drug-induced thrombocytopenia (heparin, sulfa, vancomycin)
— Drug rash (DRESS) with petechial features
— NSAID-induced platelet dysfunction
— Hemophilia, von Willebrand disease, vitamin K deficiency (infants), DIC from non-infectious cause
Board pearl: Petechiae only on face/neck after a vomiting illness in a well-appearing afebrile child = Valsalva — no extensive workup needed beyond observation. Add fever or ill appearance, and the entire sepsis workup becomes mandatory.
— Complete full IV course in hospital (meningococcemia 5–7 days; pneumococcal/Hib meningitis 10–14 days); oral step-down rarely used in invasive meningococcal disease
— Outpatient prescriptions: typically none for antibiotics; some continue prophylactic penicillin if asplenia
— Hand-carry discharge summary to PCP and specialists
— Index case: complete MenACWY and MenB series after recovery (immunization does not protect against the serogroup that caused disease if subtype-specific protection wasn't present, but covers other serogroups for future)
— Confirm or initiate MenACWY (ages 11–12, booster 16) and MenB (16–23 shared decision) in adolescents
— Hib, PCV13/15, Tdap, varicella, MMR — ensure up to date for index and siblings
— Annual influenza vaccine for index and household
— Rifampin, ciprofloxacin, or ceftriaxone for household, childcare, intimate contacts within 7 days pre-symptom — give within 24 hours
— School/daycare letter to inform other families (without identifying patient)
— Audiology evaluation (mandatory in meningitis)
— Neurologic baseline (motor, cognitive screen)
— Wound care plan for purpura fulminans lesions
— Physical/occupational therapy referral if deconditioned or with neuro deficits
— Mental health screening for patient and caregivers — PTSD/anxiety common after PICU
— Return precautions: fever recurrence, new rash, headache, seizure, behavioral change, hearing concern
— Activity restrictions per neuro/ortho recommendations
— School re-entry timeline coordinated with pediatrician
Step 3 management: Before discharge, verify (1) audiology booked, (2) ID follow-up scheduled, (3) household chemoprophylaxis given, (4) public health notified, (5) immunizations updated — these are the standard quality measures.
— 48–72 hours: Pediatrician visit — wound check, vitals, medication review, family questions
— 1 week: Infectious disease clinic — confirm clinical resolution, review cultures/sensitivities
— 2–4 weeks: Audiology repeat testing (delayed sensorineural hearing loss can emerge); neurology if any deficits or seizures
— 6 weeks: Comprehensive pediatric visit — neurodevelopmental screen, growth, immunization catch-up
— 3 months: Repeat audiology; formal neurodevelopmental assessment if any concerns (Bayley, Vineland, age-appropriate)
— 6 and 12 months: Continued monitoring for cognitive, behavioral, academic sequelae; school performance review
— Annually: Long-term audiology and developmental follow-up through school age
— Audiology: pre-discharge → 1 month → 3 months → 6 months → annually; hearing aids/cochlear implant evaluation if loss confirmed
— Neurology: EEG if seizures occurred; antiepileptic management; developmental pediatrics referral
— Plastic surgery/ortho: wound care, scar revision, prosthetic fitting for amputees, ongoing physical therapy
— Renal: BP, urinalysis, creatinine at 1, 3, 12 months if AKI occurred
— Mental health: family and patient counseling; PICU follow-up clinics where available
— Recognition of relapse/recurrence symptoms
— Vaccine importance for the patient, siblings, and future children
— Adolescent: substance use, dormitory living, MenB vaccine before college
— Caregiver support groups (Meningitis Now, NMA)
— Designate medical home / primary pediatrician as quarterback
— Shared electronic care plan among specialists
— IEP/504 plan with school if cognitive or hearing deficits
Board pearl: Sensorineural hearing loss can develop after the acute illness resolves — a normal initial audiogram does not preclude later loss, hence the 3- and 6-month repeat audiology standard.
— Parental/guardian consent for procedures (LP, central line, intubation); document emergency exception (implied consent) when life-threatening and guardian unavailable — proceed and document attempts to reach family
— Adolescent assent for age ≥7; respect their input even when not legally binding
— Mature minor doctrine varies by state — generally does not apply to life-threatening emergencies (treat regardless)
— Meningococcal disease is a reportable condition in every US state — notify health department immediately; do not wait for confirmation if clinically suspicious
— Health department coordinates contact tracing and chemoprophylaxis distribution
— Schools/daycares informed via the department, not directly by the treating physician (protects PHI)
— Petechiae in a specific distribution (neck = strangulation, ear, buttocks, abdomen) with inconsistent or implausible history → mandatory CPS report; admission for safety even if medically stable
— Skeletal survey, ophthalmology for retinal hemorrhages, social work consult
— High-risk handoffs: ED → PICU, PICU → floor, floor → discharge
— Use structured handoff (SBAR or I-PASS) with explicit medication reconciliation, pending labs, follow-up bookings, audiology appointment, public health notification status
— Discharge summary must reach PCP within 24–48 hours with explicit follow-up dates
— Tall-man lettering, dose verification, and double-checks for pediatric weight-based dosing — pediatric medication errors are common and preventable
— In catastrophic outcomes (severe brain injury, irreversible MOF), early palliative care consult complements rather than replaces curative effort
— Family-centered care: open visitation, bedside rounds, interpreter services
— Ethics consult for goals-of-care disagreements
Step 3 management: The single most tested patient safety item in this scenario is ensuring chemoprophylaxis is documented as offered to all close contacts and the case reported to public health — a missed step that has caused real-world secondary fatalities.
— N. meningitidis: gram-negative diplococci, oxidase-positive, ferments maltose AND glucose (vs gonorrhea: glucose only); polysaccharide capsule basis of serogroup vaccine
— Serogroup B: most common in US infants and adolescents; covered by MenB vaccine (Bexsero, Trumenba) only
— Serogroups C, Y, W: covered by MenACWY (Menactra, Menveo, MenQuadfi)
— Serogroup A: African meningitis belt
— Asymptomatic nasopharyngeal carriage ~10% of adolescents — explains rapid outbreaks in dormitories
— "Glass test": press a tumbler on rash — true petechiae don't blanch
— "Time = tissue": every hour of antibiotic delay in meningococcal sepsis ↑ mortality
— Waterhouse-Friderichsen = bilateral adrenal hemorrhage; refractory shock + meningococcemia
— Hib: 2, 4, 6, 12–15 months
— PCV13/15: 2, 4, 6, 12–15 months
— MenACWY: 11–12 years, booster at 16
— MenB: 16–23 years (shared clinical decision); required for asplenia, complement deficiency, eculizumab use, microbiologists, outbreak
— Procalcitonin >2 ng/mL strongly suggests bacterial
— CSF: bacterial = high neutrophils, low glucose, high protein; viral = lymphocytes, normal glucose
— Dexamethasone benefit clearest in Hib and pneumococcal meningitis
— Ceftriaxone: avoid in neonates receiving calcium-containing IV fluids (precipitation, fatal in neonates); avoid in hyperbilirubinemic neonates (displaces bilirubin)
— Rifampin: orange body fluids, OCP failure, hepatic enzyme inducer
— Hypotension is LATE; treat tachycardia, prolonged cap refill, altered mental status as shock
— Cold shock (low CO, high SVR) more common in children → epinephrine
— Warm shock (high CO, low SVR) → norepinephrine
Board pearl: Any patient receiving eculizumab or ravulizumab must have MenACWY + MenB before initiation and often takes lifelong penicillin prophylaxis — this is heavily tested.
— 18-month-old with 12 hours of fever and "purple spots" on the legs, mottled, cap refill 4 seconds, HR 180, BP 70/40 → Next step? Answer: Establish IV/IO access, give isotonic fluid bolus 20 mL/kg, AND administer IV ceftriaxone within 1 hour (not "obtain LP first," not "CT head first")
— 19-year-old college freshman admitted with confirmed meningococcal meningitis. Roommate, girlfriend (kissed last night), and biology lab partner ask about prophylaxis → Roommate and girlfriend YES (close contacts); lab partner NO (casual contact). Regimens: single-dose ciprofloxacin or ceftriaxone IM, or 2-day rifampin
— 6-year-old with fever, vomiting, neck stiffness, and altered mental status. What is the next step before LP? → Empiric IV antibiotics + dexamethasone, then CT head if focal findings/altered mental status, then LP. Never delay antibiotics for LP.
— Child with meningococcemia remains hypotensive despite 60 mL/kg fluids and epinephrine infusion → Stress-dose hydrocortisone (Waterhouse-Friderichsen suspected); consider adrenal imaging if stable
— Well-appearing 5-year-old with petechiae only on face and neck after a vomiting illness, normal vitals → Valsalva petechiae, no antibiotics, reassurance and observation
— Same child with petechiae below the nipple line + fever → full sepsis workup
— Patient starting eculizumab for atypical HUS → Administer MenACWY AND MenB at least 2 weeks before initiation; if urgent, start penicillin prophylaxis simultaneously
— Child recovering from pneumococcal meningitis, ready for discharge → Audiology evaluation before discharge is the correct next step
Key distinction: When the stem says "fever + petechiae + ill" → meningococcemia pathway. When it says "fever + petechiae + wrist/ankle onset + tick exposure" → RMSF + doxycycline. When it says "well-appearing + isolated thrombocytopenia post-viral" → ITP.
A febrile child with petechiae or purpura — especially if ill-appearing, with rash below the nipple line, or with abnormal perfusion — has invasive meningococcal disease until proven otherwise and requires IV access, blood cultures, and ceftriaxone within one hour, simultaneous fluid resuscitation, public health notification, and chemoprophylaxis of close contacts, regardless of pending diagnostic results.
CCS pearl: The case is won or lost in the first 60 minutes — antibiotics, fluids, reassessment, escalation, and public health notification are the five orders that must appear on the screen.
