# 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

- [ ] 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
