# Managing Infection Control

## Why This Skill Exists

Healthcare-associated infections (HAIs) affect approximately 1 in 31 hospital patients on any given day (CDC, 2023). The Joint Commission NPSG.07.01.01 requires compliance with hand hygiene guidelines based on CDC/WHO recommendations. CMS Conditions of Participation (§482.42) mandate an active infection prevention and control program. HAIs — including CLABSI, CAUTI, SSI, VAP, and C. difficile — are among the most preventable causes of patient harm, and CMS no longer reimburses for treatment of certain HAIs classified as Never Events. NDNQI tracks HAI rates as nursing-sensitive quality indicators. State mandatory reporting laws require disclosure of specified HAI data. This skill structures the nursing role in infection prevention: standard precautions, transmission-based precautions, surveillance, and documentation per current CDC/HICPAC guidelines.

## Checkpoint A — Intake Verification

### Required Patient Information
- [ ] Infection status: known active infections, colonization status (e.g., MRSA, VRE, CRE, C. difficile)
- [ ] Culture results (pending and finalized)
- [ ] Current antimicrobial therapy with start dates and planned duration
- [ ] Immunocompromised status (neutropenia, transplant, chemotherapy, HIV/AIDS)
- [ ] Vaccination status relevant to exposure (influenza, COVID-19, hepatitis B)
- [ ] Travel history or epidemiological risk factors for emerging pathogens
- [ ] Surgical history within 30 days (SSI surveillance window)

### Required Institutional Resources
- [ ] Infection prevention and control policy manual
- [ ] Current CDC/HICPAC transmission-based precaution guidelines
- [ ] Facility antibiogram (for empiric therapy decision support)
- [ ] Isolation signage and PPE supply status
- [ ] Hand hygiene product availability (alcohol-based hand rub, soap/water)

## Step 1 — Implement Standard Precautions

Standard precautions apply to ALL patient encounters regardless of suspected or confirmed infection status:

1. **Hand hygiene** per WHO Five Moments:
   - Before touching a patient
   - Before clean/aseptic procedures
   - After body fluid exposure risk
   - After touching a patient
   - After touching patient surroundings
2. **PPE selection** based on anticipated exposure:
   - Gloves: contact with blood, body fluids, mucous membranes, non-intact skin, contaminated items
   - Gown: anticipated contact with blood/body fluids or contaminated surfaces; during care activities likely to generate splashes
   - Mask + eye protection: procedures and care activities likely to generate splashes or sprays of blood, body fluids, secretions, excretions
3. **Respiratory hygiene / cough etiquette**: mask symptomatic patients in common areas; provide tissues and hand hygiene
4. **Sharps safety**: use safety-engineered devices; never recap needles; dispose immediately in puncture-resistant container at point of use
5. **Safe injection practices**: one needle, one syringe, one patient; single-dose vials preferred; multi-dose vials dated when opened and discarded per manufacturer instructions
6. **Environmental cleaning**: patient care equipment cleaned and disinfected between patients per institutional policy; high-touch surfaces cleaned per schedule

---

## Step 2 — Implement Transmission-Based Precautions

When standard precautions alone are insufficient, add transmission-based precautions per CDC/HICPAC:

### Contact Precautions
- **Indications**: MRSA, VRE, CRE, C. difficile, scabies, wound infections with uncontained drainage, RSV, rotavirus
- **Requirements**: Private room (or cohort); gown and gloves for all room entry; dedicated patient care equipment; enhanced environmental cleaning
- **C. difficile specific**: soap and water for hand hygiene (alcohol-based hand rub does not kill C. difficile spores); bleach-based environmental disinfection

### Droplet Precautions
- **Indications**: Influenza, pertussis, meningococcal disease, group A streptococcal pharyngitis/pneumonia, rhinovirus, adenovirus
- **Requirements**: Private room (or cohort with ≥ 3 feet separation); surgical mask within 6 feet of patient; patient wears mask during transport

### Airborne Precautions
- **Indications**: Tuberculosis (pulmonary/laryngeal), measles, varicella (chickenpox/disseminated zoster), COVID-19 (per institutional policy), smallpox
- **Requirements**: Airborne infection isolation room (AIIR) with negative pressure and ≥ 6 air changes per hour (existing) or ≥ 12 (new construction); N95 respirator (fit-tested) or PAPR for all room entry; door closed at all times; patient wears surgical mask during transport

### Protective Environment (Reverse Isolation)
- **Indications**: Allogeneic hematopoietic stem cell transplant patients, severely neutropenic patients (ANC < 500)
- **Requirements**: Positive pressure room with ≥ 12 air changes per hour; HEPA filtration; restricted visitors; no fresh flowers, plants, or uncooked fruits/vegetables

## Step 3 — Manage Invasive Device-Related Infection Prevention Bundles

### Central Line-Associated Bloodstream Infection (CLABSI) Prevention Bundle
- Hand hygiene before line access
- Scrub the hub with alcohol for ≥ 15 seconds before each access; allow to dry
- Daily assessment of line necessity — remove lines that are no longer clinically indicated
- Dressing integrity assessment each shift; change transparent dressings every 7 days, gauze every 2 days, and immediately if soiled or loosened
- Daily chlorhexidine bathing per institutional protocol

### Catheter-Associated Urinary Tract Infection (CAUTI) Prevention Bundle
- Avoid unnecessary catheterization; use nurse-driven catheter removal protocol
- Daily assessment of continued catheter necessity
- Maintain closed drainage system — never disconnect tubing
- Keep drainage bag below bladder level; do not allow it to contact the floor
- Perform perineal hygiene per institutional protocol
- Secure catheter to prevent traction and urethral trauma

### Surgical Site Infection (SSI) Prevention
- Pre-operative: appropriate antibiotic prophylaxis within 60 minutes of incision (per SCIP measures)
- Intra-operative: maintain normothermia, glucose control
- Post-operative: maintain sterile technique for dressing changes; monitor incision for signs of infection (redness, warmth, swelling, purulent drainage)

### Ventilator-Associated Pneumonia (VAP) Prevention Bundle
- Elevate HOB 30–45 degrees
- Daily sedation vacation and assessment of readiness to extubate
- Peptic ulcer prophylaxis per order
- DVT prophylaxis per order
- Oral care with chlorhexidine per institutional protocol and current evidence

## Step 4 — Conduct Infection Surveillance

1. **Monitor** for signs and symptoms of infection: fever, elevated WBC, new-onset tachycardia, wound changes, altered mental status in elderly
2. **Report** suspected HAIs to the infection preventionist per institutional policy
3. **Collect** surveillance cultures per order and protocol (blood cultures: two sets from two sites; urine culture: clean-catch or from catheter port, never from drainage bag)
4. **Track** device days: central line days, catheter days, ventilator days — the denominator for HAI rate calculations
5. **Document** compliance with prevention bundle elements per shift
6. **Report** notifiable diseases to the infection preventionist for state and local health department reporting per jurisdictional requirements

---

## Step 5 — Manage Exposure Events

1. **Needlestick/sharp injury**: Wash with soap and water immediately; report to employee health; source patient testing per protocol; initiate post-exposure prophylaxis evaluation within 2 hours for HIV exposure
2. **Blood/body fluid splash to mucous membranes**: Irrigate thoroughly; report per institutional protocol
3. **Patient exposure to communicable disease**: Identify all exposed patients and staff; implement appropriate precautions; notify infection preventionist
4. **Outbreak recognition**: Two or more epidemiologically linked cases of the same organism require investigation; report to infection preventionist immediately

---

## Step 6 — Document Infection Control Activities

1. **Isolation precautions**: type, indication, date initiated, signage placed, PPE compliance
2. **Hand hygiene**: document compliance observations per institutional monitoring program
3. **Bundle compliance**: daily documentation of each bundle element (CLABSI, CAUTI, VAP)
4. **Culture results**: time obtained, pending vs. final results, antimicrobial adjustments
5. **Exposure events**: nature of exposure, immediate actions, reporting completed, follow-up plan
6. **Patient education**: infection prevention education provided (hand hygiene, wound care, antibiotic stewardship)
