1 Janet Haas PhD, RN, CIC Rich Vogel MS, CIC Disclosures: Haas - Hand Hygiene Study funded by 3M Vogel - None VogVela Infection Prevention in Design and Construction of the Healthcare Environment 1

2 Healthcare Facility Design Goals First, do no harm Meet needs of functional program Support delivery of care model Enhance the patient environment, staff effectiveness and stewardship of the environment

3 Regulations States may have individual requirements Facilities Guidelines Institute –Publish "Guidelines for Design and Construction of Health Care Facilities" (2010) –New edition due in 2014

4 Joint Commission –“When planning for demolition, construction or renovation, the hospital conducts a preconstruction risk assessment for air quality requirements, infection control, utility requirements, noise, vibration and other hazards that affect care, treatment and services.” EC.02.06.05 EP2 

5 Infection Control Risk Assessment (ICRA) Multi-disciplinary team Design Construction Compliance Risk mitigation

6 Design Number, location and type of: –Airborne infection isolation and Protective environment rooms These cannot be switchable –Hand washing sinks, sanitizer dispensers –Eyewash stations and deluge showers HVAC systems to meet functional needs -e.g. Procedure rooms, laboratories etc. Water systems to limit legionella

7 Air Requirements General Principles - Clean to Dirty –Dirty areas (janitors closets, decontamination rooms, areas for bronchoscopy, laboratory with specimens) are negative pressure –Procedure areas, pharmacy compounding, sterile supply areas are positive pressure Best Reference is ANSI/ASHRAE/ASHE Standard 170-2008 Table 7-1

8 Airborne Isolation (AIIR) Negative Pressure = Air flows from corridor to (anteroom if present) to patient room –12 air changes/hour with 2 outside air changes/ hour Exhaust air grills in ceiling over patient head or on wall at head of bed

9 AIIR (Cont’d) Toilet and tub/shower and pt sink in the inpatient room as well as hand washing station for staff Air must be exhausted directly outside without mixing with non-AIIR exhaust Continuous visual pressure monitor Area for gowning/storage directly inside or outside of entry In retrofitted settings, can HEPA filter exhaust air Can use for non-isolation patients, but pressure settings do not change

10 Protective Environment (PE) Positive Pressure Positive Pressure = Cleanest (patient area) to less clean Supply air to PE room is HEPA filtered just before entering the room or suite of rooms –12 Air changes/ hour including 2 outside air changes/ hour Permanently installed visual mechanism to constantly monitor pressure status of the room Anteroom not required per Facilities Guidelines, but does mitigate against pressure changes 10

11 Combination AIIR/PE Room Reversible air flow NOT allowed. Air supply = PE room Exhaust air = AIIR requirements Airflow patterns may be from anteroom to both the pt room & corridor OR Airflow may be from pt room & corridor to anteroom Must have 2 visual monitors 1 between pt room and anteroom; 1 between anteroom and corridor

12 Visual Pressure Monitoring Devices

13 Legionella Prevention Design water systems to reduce risk –Scale system for actual needs (don’t over build), leads to decreased circulation around water circuits –Limit dead legs and areas of stagnation Assess need for filtration in high risk areas –Legionella in the incoming water, high risk patients, amount of water use in the area –COMMISSIONING PROCEDURES

14 Sinks Hands free Wrist blades, knee control, electronic eye Avoid aerators as these promote water dispersal Electronic eye: Save water, are popular with patients May be more prone to legionella contamination Must consider wiring to emergency power Sydnor ER et al. Electronic-eye faucets: Legionella species contamination in healthcare settings.ICHE. 2012 Mar;33(3):235-40.ICHE. HargreavesJ et al. Bacterial contamination associated with electronic faucets: a new risk for healthcare facilities. ICHE 2001Apr 22(4);202-5

15 Some Plumbing Basics Mixing Valves - control water temperature at the outlet by use of a thermostat Temperature actuated flow reduction valve - (anti-scald valve) Immediately closes in the event of a loss of cold water protecting patients from being scalded. Used primarily to control the high limit water temperature of showers. These devices may impact ability to superheat water for legionella eradication

16 Ice and Water Cold water less likely to harbor legionella Need water and ice for patient care/comfort Assure cleaning and maintenance plan is in place Assure people are trained to change filters and clean/disinfect various components of machines Trouble spots are anywhere water sits for prolonged periods Prevent contamination of ice by providing place outside of ice for the scoop

17 Flood Damage Prevention Raise Sheetrock off floor during construction.

18 Excretions/Secretions/Waste Everyday concern May contaminate environment Staff safety concern Red bag waste is costly to manage

19 Your Choice? Q: Are toilets required everywhere?

20 Technology Infrastructure Nurse call, documentation, patient education and diversion/recreation Computer cabling and device location Other controls - access hatches Water filtration Environmental disinfection technology

21 Patient Handling and Movement Assessment (PHAMA) Needs assessment to identify appropriate equipment for the service area. Definition of space and structural and other design requirements to accommodate this equipment –Prevent hallway clutter –Adequate outlets –Assure safe patient handling

22 Supply Storage Provide supplies within work flow while minimizing risk of cross contamination Just outside the patient room Outside to inside access

23 Staff Support Areas

24 Patient/Family Space For patients and families Match needs of functional program and care delivery model Assess length of stay/needs –Example: If you offer washer/dryer, then consider clothes storage space –CLUTTER PREVENTION

25 Carpeting Pleasant, inviting appearance (at least when new) Comfort and warmth underfoot Sound deadening properties No solid evidence that carpeting is linked to increased risk of HAI under normal circumstances Wet carpet is a risk for Aspergillus Gerson, SL et al. Aspergillosis Due to Carpet Contamination, ICHE 1994: 15(4) 221-3

26 Finishes Easily cleanable with hospital disinfectants Not prone to soiling with extensive use (e.g. vinyl upholstery vs. cloth) Skid-resistant No crevices for dust

27 Furnishings Cleanable/rust resistant Designed to reduce clutter Support patient mobility/independence Bed bug ‘resistant’ (limit crevices, assure no tears in upholstery)

28 Fixtures

29 Fixtures (Cont’d)

30 Antimicrobial Surfaces Copper Surfaces –Passive continuous activity; need info on exact alloys and application method; long term efficacy Curtains – become contaminated again shortly after cleaning (within 1 week) –Antimicrobial curtains may delay contamination (to 2 weeks in recent study) –May be more effective vs certain pathogens –Consider alternatives (e.g. smartglass) Schweizer M et al.

31 Summary Attention to detail at all levels ICRA is not just a permit for dust control during construction Design is something you will live with for years Don’t forget the fixtures and finishes –Thank You!

32 2010 FGI Guidelines 1.2-3.1.4 ICRA Recommendations Based on the results of the initial stage of the ICRA, the owner shall provide the following recommendations for incorporation in the functional program: (1) Design recommendations generated by the ICRA (2) Infection Control Risk Mitigation Recommendations (ICRMRs)

33 Determining Dust Control Measures STEP 1: Type of Construction STEP 2: Identify the Risk Group STEP 3: Project Class  How big is the construction project?  How ill/frail are the patients?  Non-patient area?  Ambulatory Patient / Patient access area?  In-patient area/ High risk ambulatory?  Minor repair?  Major renovation?

34 ICRA Compliance  Infection Control Risk Mitigation Recommendations (ICRMR)  Monitoring Plan  Daily/weekly checklist to verify described methods are in place  Plans which describes specific methods by which transmission of contaminates will be avoided  Barriers, negative pressure, sticky mats, HEPA filters, etc  Communication  Report checklist findings to Infection Control/Safety Committee 1.2-3.3 Compliance Elements 1.2-3.3.1 ICRA Documentation This written record shall remain an active part of the project documents for the duration of the construction project and through commissioning.

35 Dust Control Measures Patient placement Barriers and other protective measures Protection from demolition Training Debris and traffic flow Bathrooms and food for construction workers 1.2-3.4 Infection Control Risk Mitigation 1.2-3.4.1 ICRMR Planning Infection control mitigation recommendations (ICRMRs) shall be prepared by the ICRA team and shall, at a minimum, address the following:

36 Barrier For Dust Control Tight to ceiling and walls Door Closed

37 Barrier For Dust Control Zipper closed Tight to ceiling and walls Sticky mat

38 Barrier For Dust Control


40 Debris Removal Use Of Coveralls During Demolition

41 Sealed Air Ducts

42 Mobile Dust Control Devices

43 Instructions to Contractors Guidelines for Reduction of Infection Risk During Construction & Renovation  Infections associated with hospital renovations are a concern due to the vulnerability of patients who are near the construction activities. The control of infection risks (primarily airborne) during these periods is essential.  Dust containment is a critical component in the control of fungi in patient areas as well as the prevention of irritation and illness in patients, visitors and staff. It is the policy of NYP that whenever work creates an open space between construction areas and other dust or possible fungi containing areas, EHS, the Department of Epidemiology and Facilities will conduct a careful evaluation of these areas. The degree to which the project will require dust abatement measures is determined by completing an Infection Control Risk Assessment (ICRA). EHS, Epidemiology and the NYP/PM will monitor compliance with the procedures described in this policy.  Although each project is unique in items of required construction, and the location and vulnerability of nearby patients, certain general precautions are prudent. The purpose of these guidelines and the ICRA is to enhance the prevention of illness in patients who may be immune-compromised and susceptible to fungal infections and others who may be sensitive or otherwise allergic to materials found in or carried by dust.  These guidelines apply to all activities in the hospital that may create dust, aerosolize fungal spores, or generate other antigenic or irritating materials that will cause illness or discomfort and obligates EHS, Department of Epidemiology and Facilities to evaluate and monitor all such activities. All GC/CM staff are expected to comply with these requirements.
