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
