Healthcare environments must remain clean and safe for patients, staff, and visitors. Hospitals, clinics, and long-term care facilities rely on routine disinfection to prevent harmful microorganisms from spreading between people and surfaces. Yet healthcare-associated infections (HAIs)—infections acquired during medical care—continue to affect patients in healthcare facilities across Canada. The CleanSmart Healthcare Disinfection Series explains why this challenge persists and how safer disinfection strategies are emerging in modern healthcare environments.

Why Healthcare Disinfection Matters
Healthcare facilities perform thousands of cleaning and disinfection tasks every day. Patient rooms, medical equipment, waiting areas, and shared surfaces must all be cleaned regularly to prevent microorganisms from spreading between patients and staff. When these microorganisms move through healthcare environments, they can lead to healthcare-associated infections.
Healthcare-associated infections (HAIs) are infections that patients acquire while receiving medical treatment. These infections may occur in hospitals, outpatient clinics, surgical centres, or long-term care facilities. They can extend hospital stays, increase healthcare costs, and in severe cases cause preventable illness or death.
Environmental cleaning therefore plays a critical role in infection prevention. Effective disinfection practices help break the chain of transmission by removing microorganisms from surfaces that patients and staff touch frequently.
Challenges with Traditional Hospital Disinfectants
Many healthcare facilities rely on long-established disinfectants such as bleach, hydrogen peroxide, and quaternary ammonium compounds (QACs). Quaternary ammonium compounds are a group of chemical disinfectants widely used in healthcare because they can kill many types of microorganisms on surfaces.
However, these products can also introduce challenges in healthcare environments. Strong chemical fumes may irritate the lungs and skin of staff and patients, repeated use can damage medical equipment and building materials, and some pathogens are gradually adapting to certain disinfectant chemicals.
Healthcare organizations are increasingly reviewing the role of these disinfectants as they seek solutions that balance effectiveness, staff safety, and operational efficiency.

Protecting Healthcare Workers from Chemical Exposure
Environmental services teams, nurses, and other healthcare staff perform cleaning tasks repeatedly throughout each shift. Because disinfectants are applied frequently and often in occupied spaces, healthcare workers may experience repeated exposure to cleaning chemicals.
Over time, research has linked repeated exposure to certain disinfectants with respiratory irritation, skin irritation, and occupational asthma. Occupational asthma refers to asthma that develops or worsens because of workplace exposure to airborne substances.
Healthcare administrators must therefore balance two important priorities: preventing infections and protecting staff health. Choosing disinfectants that reduce unnecessary chemical exposure can help support both infection control and workplace safety.

Articles in the Healthcare Disinfection Series
The Healthcare Disinfection Series examines infection control from several perspectives, beginning with the broader infection-control challenge and then exploring disinfectant performance and worker safety.
1. The Disinfectant Dilemma: Tackling Healthcare-Associated Infections in Canada
Healthcare-associated infections remain a significant issue in Canadian healthcare facilities. This article explains why infection rates remain difficult to control and why traditional disinfectants are increasingly questioned in modern healthcare environments.
2. Why Traditional Disinfectants Fail in Canadian Hospitals
Bleach, quaternary ammonium compounds, and hydrogen peroxide are widely used in hospitals, yet these chemicals create operational and safety challenges. This article examines the limitations of traditional disinfectants and explains why healthcare organizations are exploring safer alternatives.
3. Protecting Frontline Staff: Reducing Chemical Exposure in Healthcare Settings
Healthcare workers experience repeated exposure to disinfectants while performing infection-control tasks. This article explores the health risks associated with chemical exposure and explains how safer disinfection strategies may reduce these risks without compromising infection prevention.
What This Series Explores
Healthcare disinfection involves more than simply selecting a cleaning product. Infection prevention depends on understanding how microorganisms spread, how disinfectants work, and how cleaning procedures affect both staff and patients.
The articles in this series explore several important topics related to healthcare disinfection:
- why healthcare-associated infections remain difficult to control
- how traditional disinfectants affect staff health and workplace safety
- why some pathogens adapt to commonly used disinfectant chemicals
- how cleaning protocols influence workflow in hospitals and clinics
- what characteristics make disinfectants safer for healthcare environments
Each article focuses on one part of this larger infection-control picture so readers can better understand both the risks and the possible solutions.
Healthcare Disinfection FAQ
Q1. What are healthcare-associated infections?
Healthcare-associated infections are infections that patients develop while receiving treatment in a healthcare facility. These infections may occur when microorganisms spread through contact with contaminated surfaces, equipment, or healthcare workers.
Q2. Why are traditional hospital disinfectants being questioned?
Some commonly used disinfectants produce strong fumes, irritate skin and lungs, or require long contact times to work effectively. In addition, certain microorganisms are showing increasing tolerance to some disinfectant chemicals.
Q3. What is occupational asthma?
Occupational asthma is asthma caused or worsened by substances in the workplace. Healthcare workers exposed repeatedly to cleaning chemicals may face an increased risk of respiratory irritation or asthma symptoms.
Q4. Are safer disinfectants available for healthcare environments?
Yes. Some newer disinfectants aim to reduce toxic fumes and chemical residues while still meeting infection-control standards required in healthcare facilities.
Q5. Why is environmental cleaning important in healthcare?
Environmental cleaning removes microorganisms from surfaces that patients and staff touch frequently. Effective disinfection helps reduce the spread of infections within healthcare environments.
How to Use This Series
Each article in the Healthcare Disinfection Series can be read independently. Readers who are new to healthcare infection control may wish to begin with the article explaining healthcare-associated infections before exploring the topics of disinfectant performance and worker safety.
Together, the articles provide a broader understanding of how infections spread in healthcare environments and how safer disinfection strategies can help reduce risk.
Moving Toward Safer Healthcare Disinfection
Healthcare facilities must protect both patients and staff while maintaining strict infection-control standards. As new research highlights the health risks associated with certain cleaning chemicals, many organizations are reviewing the disinfectants used in their facilities.
Hypochlorous acid (HOCl) is one disinfectant technology receiving increasing attention in healthcare environments. Hypochlorous acid is a compound naturally produced by the human immune system that can kill microorganisms while producing fewer harsh fumes than many traditional disinfectants.
