Infection control in healthcare settings gets a lot of attention — as it should. Healthcare-associated infections (HAIs) affect hundreds of thousands of patients in Canadian healthcare facilities each year, resulting in significant patient harm, increased length of stay, and elevated healthcare costs. The environmental factors that contribute to HAIs are well-studied, and the built environment — including the condition of walls — plays a role that is often underappreciated in facility management discussions.
This article examines the specific connection between wall condition, wall protection systems, and infection control outcomes in healthcare settings. It’s written for facility managers, infection control professionals, and anyone involved in capital planning for hospitals, long-term care facilities, and clinical buildings.
The Infection Control Problem With Damaged Walls
The core problem is cleanability. Modern infection control protocols in healthcare settings depend on the ability to clean and disinfect all surfaces effectively. Surfaces that are cracked, porous, chipped, or damaged cannot be cleaned to the same standard as intact surfaces — and the gaps, crevices, and porous areas created by damage provide reservoirs where microbial contamination can persist even after standard cleaning.
Consider what standard drywall looks like at the microscopic level after it’s been chipped, gouged, or cracked. The paper facing is torn. The gypsum core is exposed — a porous, irregular surface with thousands of small spaces where organic material and moisture can accumulate. Bacteria survive and grow in exactly these conditions. Standard hospital-grade cleaners, applied by standard cleaning methods, cannot reliably decontaminate a damaged drywall surface to the same degree as they can an intact, smooth, non-porous surface.
Now consider how much impact damage occurs in a busy hospital corridor over the course of a year. Dozens of carts, beds, and equipment impacts. Each one a potential compromise of the wall surface. Each compromise a potential harboring site for pathogens.
The Evidence: What Research Shows
Several pathogens of particular concern in healthcare settings are directly relevant to this discussion.
Aspergillus and Fungal Infections
Aspergillus species are filamentous fungi that are found virtually everywhere in the environment. For healthy people, exposure to Aspergillus spores is harmless. For immunocompromised patients — transplant recipients, patients on chemotherapy, those with certain blood disorders — Aspergillus can cause invasive pulmonary aspergillosis, a life-threatening infection.
The construction and renovation environment is particularly associated with Aspergillus risk, because disturbing building materials releases spores. But ongoing maintenance considerations matter too: wall surfaces that accumulate moisture and organic material in cracks and damage sites can harbor fungal growth. In high-risk patient areas, the condition of wall surfaces is an infection control issue — not just a maintenance issue.
Clostridium difficile (C. diff)
C. diff is one of the most significant HAI pathogens in long-term care and hospital settings. Its spores are remarkably persistent in the environment — they can survive for months on surfaces, resist many standard disinfectants, and are spread primarily through contact with contaminated environmental surfaces.
Thorough environmental cleaning and disinfection is a cornerstone of C. diff control. Damaged wall surfaces — cracks, chips, and porous areas — complicate this effort. Research consistently shows that areas of environmental complexity (surfaces that are difficult to clean thoroughly) have higher rates of residual C. diff contamination after standard cleaning procedures.
Methicillin-Resistant Staphylococcus aureus (MRSA)
MRSA is a major HAI concern in both hospital and long-term care settings. Like C. diff, it can persist on environmental surfaces. Wall surfaces in patient care areas that are difficult to clean effectively contribute to the environmental reservoir of MRSA. Facilities with better environmental cleaning outcomes — including easier-to-clean wall surfaces — consistently show lower environmental contamination rates.
What Wall Protection Products Offer From an Infection Control Perspective
Modern institutional wall protection products are designed with cleanability as a primary requirement. Here’s how the leading products address infection control needs.
Acrovyn® Wall Protection Systems
Acrovyn® (Construction Specialties) products are specifically engineered and tested for healthcare environments. The material is:
- Non-porous: Unlike drywall, Acrovyn’s vinyl composite surface doesn’t absorb moisture or microbial contamination. Cleaning agents contact the full surface rather than being absorbed into the substrate.
- Chemical resistant: Acrovyn is tested against a range of hospital disinfectants, including oxidizing agents, quaternary ammonium compounds, and bleach-based products. It maintains its surface integrity and cleanability after repeated exposure to these agents — something standard paint over drywall cannot claim.
- Impact resistant: This is the core feature from an infection control standpoint. A wall covered in Acrovyn doesn’t get chipped, cracked, or gouged under normal institutional use. The surface integrity is maintained, which means the cleanability is maintained.
- Seamless surface: Properly installed Acrovyn wall sheets and accessories create a continuous, smooth surface without the crevices and joints that characterized older tile and grout wall coverings. Fewer joints mean fewer harboring sites.
Stainless Steel Wall Protection
Stainless steel offers the highest level of infection control performance of any wall protection material used in healthcare settings:
- True non-porosity: Stainless steel has essentially no surface porosity. Disinfectants work at full concentration on the entire surface.
- Sterilization compatibility: In operating rooms and procedure rooms, stainless steel wall protection can be subjected to the same decontamination protocols as surgical instruments. No other wall material can make this claim.
- Durability: Stainless steel doesn’t chip, crack, or degrade under impact. The surface integrity — and therefore the cleanability — is permanent.
- Chemical resistance: Stainless steel (particularly 316 grade) resists virtually all hospital cleaning and disinfection chemicals without surface degradation.
Accreditation and Regulatory Implications
Wall condition is directly relevant to healthcare accreditation in Canada. Accreditation Canada — which accredits hospitals and long-term care facilities — includes physical environment standards that encompass the condition of surfaces in patient care areas. Environmental rounds by accreditation surveyors will note damaged walls in patient care areas as findings.
Provincial inspection programs for long-term care homes in Ontario — conducted under the Fixing Long-Term Care Act — similarly include physical environment inspections. Persistent wall damage in resident care areas can generate compliance orders that require remediation on a defined timeline.
Infection control standards from Public Health Ontario and the Provincial Infectious Diseases Advisory Committee (PIDAC) provide guidance on environmental cleaning in healthcare settings that implicitly requires cleanable surfaces. Facilities with ongoing wall damage issues are in a perpetually compromised position relative to these standards.
Making the Business Case for Wall Protection in Healthcare
In a healthcare setting, the business case for wall protection is stronger than in any other building type, because the stakes are higher. Here’s the multi-level value proposition:
- Direct repair cost avoidance: Eliminating the ongoing cost of reactive wall repairs is the most straightforward financial argument. In a busy hospital corridor, this can represent thousands of dollars annually per corridor.
- Infection control risk reduction: The infection control argument is harder to quantify but potentially the most significant. Each HAI event carries an estimated average cost of $10,000 to $40,000 in additional treatment costs, plus immeasurable patient harm. Environmental factors that contribute to HAI risk — including uncleananable surfaces — are worth addressing with urgency.
- Reduced disruption from repairs: Every wall repair in an occupied patient care area carries infection control risk from construction dust, requires clinical area closure or restrictions, and disrupts patient care. Eliminating the need for these repairs eliminates the associated risks.
- Accreditation and compliance: Facilities that maintain wall protection systems in good condition consistently present better physical environments during accreditation surveys, reducing the risk of findings and compliance orders.
