Managing Central Line Care

Why This Skill Exists

Central line-associated bloodstream infections (CLABSIs) affect approximately 30,000 patients annually in U.S. ICUs, with attributable mortality of 12–25% and excess costs of $16,000–$45,000 per episode. CMS classifies CLABSI as a Hospital-Acquired Condition with reimbursement implications under the HAC Reduction Program. Joint Commission NPSG.07.06.01 requires implementation of evidence-based CLABSI prevention practices. The CDC/HICPAC Guidelines for Prevention of Intravascular Catheter-Related Infections provide the evidence base. The IHI Central Line Bundle has demonstrated that consistent implementation of 5 evidence-based interventions can reduce CLABSI rates to near zero. NDNQI tracks CLABSI rates as a nursing-sensitive quality indicator. This skill structures the nursing management of central venous catheters from insertion assistance through maintenance, daily assessment, and removal per current evidence-based guidelines.

Checkpoint A — Intake Verification

Required Patient Information

  • [ ] Central line type: non-tunneled CVC, tunneled CVC (Hickman/Broviac), PICC, implanted port
  • [ ] Insertion date and site (subclavian, internal jugular, femoral, upper arm for PICC)
  • [ ] Number of lumens and current lumen assignments (infusions, monitoring, blood draws)
  • [ ] Indication for central line (medication administration requiring central access, hemodynamic monitoring, TPN, lack of peripheral access, renal replacement therapy)
  • [ ] Tip confirmation: chest x-ray confirming catheter tip at the cavoatrial junction (CVC/PICC)
  • [ ] Allergy status: chlorhexidine, adhesive, latex
  • [ ] Patient's infection risk factors: immunosuppression, prolonged hospitalization, TPN, multiple lumens

Required Equipment

  • [ ] Chlorhexidine gluconate (CHG) skin antiseptic
  • [ ] Sterile transparent semi-permeable dressing or CHG-impregnated dressing
  • [ ] Catheter securement device
  • [ ] Needleless access connectors
  • [ ] 10 mL prefilled normal saline syringes (≥ 10 mL to prevent catheter fracture)
  • [ ] Alcohol prep pads or CHG caps for hub disinfection
  • [ ] Sterile gloves and sterile drape for dressing changes

Step 1 — Assist with Insertion (If Applicable)

The central line insertion bundle must be implemented for every insertion:

  1. Hand hygiene performed by all team members
  2. Maximal sterile barrier precautions: inserter wears sterile gown, sterile gloves, cap, mask; patient draped with full-body sterile drape
  3. Chlorhexidine skin antisepsis: > 0.5% CHG in alcohol solution applied to insertion site with friction for ≥ 30 seconds; allow to dry completely (approximately 2 minutes)
  4. Optimal site selection: subclavian preferred for lowest CLABSI risk (non-tunneled CVC); avoid femoral site when possible (highest infection risk); use internal jugular for temporary dialysis access
  5. Daily review of line necessity: begins immediately — the line should only remain as long as clinically indicated
  6. Nursing role during insertion:
    • Ensure all bundle elements are followed; RN has the authority and responsibility to stop the procedure if sterile technique is broken
    • Monitor patient during insertion (vital signs, ECG for dysrhythmias during guidewire advancement)
    • Prepare sterile field and supplies
    • Document insertion: date, time, inserter, site, line type, number of lumens, skin prep, confirmation of maximal barrier precautions, patient tolerance, tip confirmation method

Step 2 — Perform Daily Central Line Assessment

Assess at each shift and document:

  1. Insertion site inspection (through transparent dressing without removing):
    • Redness, swelling, tenderness, warmth, drainage
    • Suture/securement device integrity
    • Signs of catheter migration (external length has changed)
  2. Dressing condition: Clean, dry, intact, occlusive; edges adherent without lifting
  3. Line patency: Each lumen flushes easily; blood return present when aspirated
  4. Tubing and connections: All connections secure; no disconnections or cracks
  5. CHG cap/alcohol cap in place on all non-infusing lumens
  6. Line necessity assessment: Answer: "Does this patient still need this central line today?"
    • If NO → advocate for removal; document discussion with provider
    • If YES → document the ongoing clinical indication

Step 3 — Perform Central Line Dressing Changes

Per CDC/HICPAC and INS standards:

  1. Frequency:
    • Transparent semi-permeable dressing: change every 7 days
    • CHG-impregnated dressing (BioPatch, Tegaderm CHG): change every 7 days
    • Gauze dressing: change every 2 days
    • Change immediately if soiled, loosened, damp, or integrity compromised
  2. Technique:
    • Perform hand hygiene; don clean gloves to remove old dressing
    • Inspect the site after old dressing removal
    • Perform hand hygiene again; don sterile gloves
    • Clean the site with > 0.5% CHG in alcohol using friction for ≥ 30 seconds
    • Allow to dry completely (do not blow or fan dry)
    • Apply CHG-impregnated disc (BioPatch) if per institutional protocol, with the clear side against the skin surrounding the insertion site
    • Apply transparent dressing; press firmly to ensure adherence
    • Date and initial the dressing
  3. Document: date, time, site condition, dressing applied, nurse initials

Step 4 — Maintain the Central Line

Hub/Port Disinfection (Scrub the Hub)

  • Scrub all needleless access connectors with 70% isopropyl alcohol or CHG/alcohol for ≥ 15 seconds using friction before every access
  • Allow to dry completely before accessing
  • Alternative: use CHG-impregnated port protector caps on all non-infusing lumens

Flushing Protocol

  • Flush each lumen with ≥ 10 mL preservative-free 0.9% sodium chloride before and after each use
  • Use pulsatile (push-pause) technique
  • Lock unused lumens per institutional protocol (heparin lock or normal saline per policy and catheter type)
  • Use ≥ 10 mL syringes to prevent catheter fracture from excessive pressure

Tubing Management

  • Primary continuous infusion sets: change no more frequently than every 96 hours (unless integrity compromised)
  • Intermittent infusion sets: change every 24 hours
  • Blood product administration sets: change after each unit or every 4 hours
  • Lipid-containing infusions: change every 24 hours
  • Needleless connectors: change per manufacturer recommendation and institutional policy

Daily CHG Bathing

  • Perform daily CHG bathing for all patients with central lines per institutional protocol
  • Use 2% CHG-impregnated cloths; bathe from neck down, avoiding face, mucous membranes, and open wounds
  • Allow to air dry (do not rinse)

Step 5 — Monitor for and Manage Central Line Complications

CLABSI Suspicion

  • Signs: fever, chills, rigors, hypotension, tachycardia, site erythema/drainage
  • Action: obtain blood cultures (two sets peripherally AND one set from each CVC lumen, per institutional protocol) BEFORE antibiotics; notify provider; document findings and cultures obtained
  • Do not remove the catheter until directed by the provider (some infections can be treated with antibiotic lock therapy)

Catheter Occlusion

  • Signs: inability to flush, inability to aspirate blood return, sluggish infusion
  • Action: attempt to aspirate clot; do not forcefully flush; notify provider for alteplase (tPA) instillation order if thrombotic occlusion suspected

Pneumothorax (Post-Insertion Complication)

  • Signs: sudden dyspnea, chest pain, decreased breath sounds on affected side, tracheal deviation (tension pneumothorax)
  • Action: stat chest x-ray; prepare for chest tube insertion if tension pneumothorax; notify provider immediately

Air Embolism

  • Signs: sudden dyspnea, chest pain, hypotension, altered consciousness
  • Action: clamp catheter; position patient left lateral Trendelenburg; administer 100% oxygen; call rapid response/code

Catheter Migration/Dislodgement

  • Signs: change in external catheter length, difficulty flushing, resistance to infusion, dysrhythmias
  • Action: do not use the catheter; secure to prevent further migration; notify provider; chest x-ray for tip confirmation

Step 6 — Document Central Line Care

  1. Daily assessment: site condition, dressing integrity, patency of each lumen, line necessity review, CHG bathing compliance
  2. CLABSI prevention bundle compliance: hand hygiene, hub disinfection, dressing condition, line necessity review, CHG bathing — document ALL 5 elements each shift
  3. Dressing changes: date, time, site condition, antiseptic used, dressing type, nurse initials
  4. Line access: each access event documented with hub scrub and flush
  5. Complications: detailed description, interventions, provider notification, patient response
  6. Removal: date, time, reason, line integrity (tip intact), site condition, hemostasis achieved, dressing applied

Checkpoint B — Central Line Maintenance Review

Shift-Level Bundle Compliance Check

  • [ ] Hand hygiene performed before every line access
  • [ ] Hub scrubbed for ≥ 15 seconds before every access
  • [ ] Dressing clean, dry, intact, dated within policy timeframe
  • [ ] Line necessity reviewed and documented
  • [ ] CHG bathing performed per institutional protocol
  • [ ] All non-infusing lumens capped with CHG/alcohol caps

Weekly Review

  • [ ] Line days tracked (cumulative days since insertion)
  • [ ] CLABSI events: zero (if not zero, investigate)
  • [ ] Dressing changes performed on schedule
  • [ ] Tip position re-confirmed if concern for migration

Quality Audit

  • [ ] Central line insertion bundle compliance documented: maximal barrier, CHG prep, optimal site selection
  • [ ] Daily CLABSI prevention bundle compliance ≥ 95% per NDNQI benchmark
  • [ ] Line necessity assessed daily with documentation of ongoing indication
  • [ ] Central line days tracked per unit (denominator for CLABSI rate calculation)
  • [ ] CLABSI rate benchmarked against NHSN national data (SIR target < 1.0)
  • [ ] Hub scrub compliance documented per institutional monitoring program
  • [ ] CHG bathing compliance documented per institutional protocol
  • [ ] Dressing changes within INS/CDC timeframe standards
  • [ ] Compliant with Joint Commission NPSG.07.06.01 (evidence-based CLABSI prevention)
  • [ ] Compliant with CMS HAC Reduction Program requirements for CLABSI reporting

Guidelines

  • CDC/HICPAC: Guidelines for Prevention of Intravascular Catheter-Related Infections (2011, with ongoing updates) — the evidence base for central line care
  • IHI Central Line Bundle: Hand hygiene, maximal barrier precautions, CHG skin antisepsis, optimal site selection, daily line necessity review
  • Joint Commission NPSG.07.06.01: Implement evidence-based practices for prevention of CLABSI
  • INS Standards of Practice (2021): Vascular access device maintenance, dressing change frequency and technique, flushing protocols
  • CMS HAC Reduction Program: CLABSI is a scored HAI; hospitals in the bottom quartile face payment reduction
  • NDNQI: CLABSI rate per 1,000 central line days is a nursing-sensitive quality indicator
  • NHSN: National Healthcare Safety Network — standardized CLABSI surveillance definitions and benchmarking
  • Scope of practice: RN assesses central line sites, performs dressing changes, accesses central lines, and monitors for complications; PICC insertion may be within advanced RN scope per state Nurse Practice Act; CVC insertion is a provider procedure; RN is empowered and expected to stop insertion procedures when sterile technique is compromised
  • Empowerment: The RN has the authority and responsibility to advocate for central line removal when the line is no longer clinically indicated — this is a key CLABSI prevention strategy
