Infection Prevention and Control: Comprehensive Facility Guidelines

Core Cleaning and Disinfection Protocols

Use EPA-registered hospital detergent/disinfectants for all patient-care areas, following manufacturer's instructions for dilution and contact time, and never use high-level disinfectants or liquid chemical sterilants on environmental surfaces. 1

Selection and Use of Cleaning Agents

Standard Environmental Surfaces

• EPA-registered hospital detergent/disinfectants are the primary agents for patient-care areas where contamination with blood, body fluids, or multidrug-resistant organisms is uncertain 1
• Detergent and water alone suffice for non-patient-care areas (administrative offices) 1
• Do NOT use alcohol for large environmental surface disinfection 1
• Do NOT use high-level disinfectants (liquid chemical sterilants) on any environmental surfaces—this violates FDA label instructions due to chemical toxicity 1

Special Pathogen Considerations

For Clostridium difficile contamination:

• Use hypochlorite-based products (household bleach diluted 1:10 for general surfaces)
• Standard EPA-registered disinfectants are insufficient for C. difficile spores 1

For Creutzfeldt-Jakob Disease (CJD) contamination:

• Routine cleaning: Standard procedures are adequate for rooms without CNS tissue contamination 1
• CNS tissue contamination: Use either:
  • 1N sodium hydroxide (NaOH), OR
  • Sodium hypochlorite 10,000-20,000 ppm (1:5 to 1:3 dilution of household bleach)
  • Contact time: 30-60 minutes
  • Blot with absorbent material, rinse thoroughly, discard waste appropriately 1

For blood spills:

• Follow standard bloodborne pathogen procedures
• Use appropriate PPE during decontamination
• Apply EPA-registered disinfectant after cleaning 1

Specialized Cleaning Agents by Application

For hard water scale and biofilm removal (particularly on taps and fixtures):

• Phosphoric acid-based environmental detergents are most effective
• Standard agents (citric acid, baking soda, ethanol, sodium hypochlorite) fail to remove hard scale effectively
• This approach reduces bacterial counts and eliminates carbapenem-resistant organisms 2

Preparation and Application Protocols

Daily Solution Preparation

• Prepare cleaning solutions fresh daily or as needed 1
• Replace solutions frequently per facility policy 1
• Never reuse contaminated solutions

Mop and Cloth Management

• Change mop heads at the beginning of each day 1
• Change immediately after cleaning large blood/body fluid spills 1
• Clean mops and cloths after each use and allow complete drying before reuse 1
• Alternative: Use single-use disposable mop heads and cloths 1

Application Technique

• Wet-dust horizontal surfaces using cloths moistened with EPA-registered hospital detergent/disinfectant 1
• Avoid dry dusting or feather-dusting methods that disperse particles 1
• Do NOT perform disinfectant fogging 1
• Avoid cleaning methods that produce mists, aerosols, or disperse dust 1

Surface-Specific Cleaning Frequencies

High-Touch Surfaces (Clean More Frequently)

• Doorknobs
• Bed rails
• Light switches
• Toilet surfaces in patient rooms
• Medical equipment controls 1

Minimal-Touch Surfaces (Clean on Regular Schedule)

• Floors
• Walls (only when visibly dusty or soiled)
• Window blinds and curtains (when visibly soiled) 1

Special Area Protocols

Operating Rooms

• After final procedure of day/night: Wet vacuum or mop floors with single-use mop and EPA-registered hospital disinfectant 1
• Do NOT use tacky mats at entrances 1

Immunocompromised Patient Areas

• Wet-dust horizontal surfaces daily 1
• Use HEPA-filtered vacuums in good repair 1
• Close patient room doors when vacuuming, waxing, or buffing corridor floors 1
• Minimize dust dispersion at all times 1

Neonatal Units

• Avoid unnecessary neonatal exposure to disinfectant vapors during low/intermediate-level disinfection 1

Equipment-Specific Cleaning

Noncritical Medical Equipment

• Follow manufacturer's cleaning instructions when available 1
• When instructions absent:
  • Clean with detergent/disinfectant
  • Follow with EPA-registered hospital disinfectant (with or without tuberculocidal claim based on contamination level)
  • Apply according to germicide label instructions 1

Barrier Protection Strategy

Use disposable barrier coverings for surfaces that are:

• Touched frequently with gloved hands during patient care
• Likely contaminated with blood/body substances
• Difficult to clean (e.g., computer keyboards) 1

Critical Implementation Pitfalls to Avoid

Common errors that compromise infection control:

1. Using wrong disinfectant concentration - Always follow manufacturer's dilution instructions precisely 1
2. Insufficient contact time - Disinfectants require specific contact times to be effective; surfaces must remain wet for the specified duration 1
3. Cleaning without prior removal of organic matter - Soil and debris inactivate disinfectants; always clean before disinfecting 3
4. Reusing contaminated cleaning solutions - This spreads pathogens rather than eliminating them 1
5. Using high-level disinfectants on surfaces - This is toxic, violates FDA regulations, and is unnecessary 1

The Four-Step Systematic Cleaning Protocol

A structured approach ensures thoroughness and reduces infection risk 4:

Step 1: LOOK - Visually assess the area for contamination, damage, and cleaning priorities

Step 2: PLAN - Prepare the bed space, gather appropriate supplies, ensure proper PPE

Step 3: CLEAN - Execute surface cleaning/decontamination using appropriate agents and techniques

Step 4: DRY - Allow surfaces to air dry completely (critical for disinfectant efficacy)

Multidisciplinary Team Requirements

Establish a team including 1:

• Infection control practitioners
• Environmental services professionals
• Facility managers
• Nursing staff
• Engineers
• Administrators

This team conducts infection-control risk assessments and ensures protocol adherence across all facility areas.

Monitoring and Compliance

Do NOT conduct random environmental sampling unless part of an epidemiologic investigation or hazard assessment 1

Bundle approach for effective implementation 5:

1. Create evidence-based policies and procedures
2. Select appropriate cleaning/disinfecting products
3. Educate all staff (environmental services, nursing, patient equipment handlers)
4. Monitor compliance with feedback and just-in-time coaching
5. Implement "no-touch" room decontamination technology for contact/enteric precautions

Construction and Renovation Considerations

During construction, repair, or demolition 1:

• Use dust-control procedures and barriers
• Conduct infection-control risk assessments
• Consider airborne-particle sampling to verify air filtration effectiveness
• Protect high-risk patient areas with enhanced environmental controls
