Vet Hospital Infections: How Common Are They?

Hospital-acquired infections (HAIs) are a growing concern in veterinary hospitals, with the frequency likely to increase. HAIs are associated with increased mortality, morbidity, and economic burden due to extended hospital stays. In veterinary medicine, urinary tract infections, pneumonia, surgical site infections, bloodstream infections, and gastrointestinal disease (infectious diarrhea) are the most common HAIs. These infections can be caused by antimicrobial-resistant bacteria, which is an increasing problem in veterinary hospitals. The presence of bacterial pathogens in veterinary settings emphasizes the need for infection prevention and control measures, such as proper hand hygiene, risk reduction, and routine practices. Surveillance programs are also important to monitor specific outbreaks and establish a baseline for HAI incidences.

Hospital-acquired infections (HAIs) are associated with increased mortality, morbidity, and economic burden

Hospital-acquired infections (HAIs) are a significant concern in veterinary hospitals, with potential implications for both animal and human health. HAIs are associated with increased mortality, morbidity, and economic burden, and their impact can be far-reaching.

HAIs in veterinary settings can have serious consequences for animal patients, leading to increased morbidity and mortality rates. Animals undergoing surgery, for instance, are particularly vulnerable to postoperative wound infections and surgical site infections (SSIs). Additionally, HAIs can contribute to the development of antimicrobial-resistant bacteria, which can be challenging to treat and may require alternative, more expensive treatments. This can result in extended hospital stays for affected animals, further increasing the economic burden on pet owners or caregivers.

The frequency of HAIs in veterinary hospitals is likely to increase, and they can affect veterinary hospitals of all types and sizes. Urinary tract infections, pneumonia, bloodstream infections, surgical site infections, and infectious diarrhea are among the most common types of HAIs in veterinary medicine. These infections can be caused by various pathogens, including MDR Escherichia coli, extended-spectrum β-lactamase (ESBL)-producing E. coli, Salmonella Typhimurium, and methicillin-resistant Staphylococcus pseudintermedius (MRSP).

The hospital environment itself can be a source of HAIs, with contaminated surfaces and equipment posing risks. Tables, chairs, floors, and surgical environments in veterinary facilities have been found to harbor pathogens, and some organisms, such as MRSP, can survive cleaning and disinfection, particularly if disinfectants are not used at the correct concentrations. This highlights the importance of proper disinfection protocols and the selection of effective disinfectants.

Infection control and surveillance are crucial in mitigating the impact of HAIs. Surveillance programs help establish a baseline rate of HAIs and monitor specific outbreaks. However, the importance of surveillance is often overlooked within the veterinary community, and many practices lack systematic data collection and analysis, leading to a false sense of security and a failure to address the risk of HAIs effectively. Implementing comprehensive infection control programs, including hand hygiene, risk assessment, education, and proper wound care, is essential to reducing the incidence of HAIs and protecting the health of animals, veterinary staff, and the broader community.

HAIs are constantly changing and mutating, so biosecurity measures are important

Hospital-acquired infections (HAIs) are a growing concern in veterinary hospitals of all types and sizes, and their frequency is likely to increase. Urinary tract infections, pneumonia, bloodstream infections, surgical site infections, and infectious diarrhea are the most common HAIs in veterinary medicine. Other possible infections include upper respiratory tract infection, dermatophyte infection, iatrogenic blood-borne pathogen infection, and infections of a wide range of invasive devices.

HAIs are constantly changing and mutating, and some bugs that were once considered harmless can now cause acute death within 24 hours. The 2018 AAHA Infection Control, Prevention, and Biosecurity (ICPB) Guidelines highlight that many nosocomial or hospital-acquired infections (HAIs) go unnoticed. This means that relying solely on the awareness of outbreaks as a measure of effective ICPB practices can lead to a false sense of security and unnecessary health risks for patients and staff.

The patient microbiota, healthcare workers, fomites, and the hospital environment have been identified as possible sources of organisms associated with HAIs. Therefore, it is critical to identify the sources of these organisms to reduce the risk of transmission to patients and humans. Veterinary clinics and hospitals must implement infection prevention and control measures to eliminate these pathogens. This includes ensuring proper disinfection of surfaces and equipment, as some pathogens can survive cleaning and disinfection and become a source of infection for susceptible animals.

To address the evolving nature of HAIs, biosecurity measures are essential. Biosecurity refers to the practices and procedures put in place to prevent the introduction and spread of infections within a facility. This includes both conceptual biosecurity, which involves the physical isolation of animal facilities, and procedural biosecurity, which involves routine procedures such as showering, changing clothes, washing hands, and disinfecting equipment. Additionally, staff education is crucial, as all staff members should be aware of the risks and signs associated with HAIs to enable early detection and appropriate management.

The patient microbiota, healthcare workers, and the hospital environment are possible sources of HAIs

Hospital-acquired infections (HAIs) are a growing problem in veterinary hospitals of all types and sizes. HAIs are associated with increased mortality, morbidity, and economic burden due to extended hospital stays. Urinary tract infections, pneumonia, bloodstream infections, surgical site infections, and infectious diarrhea are the most frequently identified HAIs in veterinary medicine.

Healthcare workers' microbiota has been identified as one of the main risk factors in the dissemination of HAI-related bacteria. The microbiota of corporal surfaces from healthcare workers is similar to the microbial communities present in hospital environments due to the dynamics and interaction of healthcare workers between facilities within the hospital. The resting rooms of healthcare workers have been found to be the most contaminated sites with a high amount of both total bacteria and HAI-related bacteria.

The hospital environment, including floors, tables, chairs, and surgical environments, can harbor multidrug-resistant pathogens, such as MRSP, which can survive cleaning and disinfection. Ineffective cleaning and the use of incorrect disinfectant concentrations can contribute to the spread of infections.

The identification of the sources of organisms associated with HAIs in veterinary settings is critical to reducing the risk of transmission to patients and humans. Understanding the relationship between environmental cleanliness and the risk of transmission is an ongoing area of study.

HAIs are a growing problem in veterinary medicine, with limited research available

Hospital-acquired infections (HAIs) are a growing problem in veterinary medicine, with limited research available. HAIs occur in veterinary hospitals of all types and sizes, and their frequency is likely to increase. Urinary tract infections, pneumonia, bloodstream infections, surgical site infections, and infectious diarrhea are among the most common HAIs in veterinary medicine. Other conditions such as upper respiratory tract infections, dermatophyte infections, and iatrogenic blood-borne pathogen infections can also occur.

The presence of bacterial pathogens within veterinary settings is a public health concern. The patient microbiota, healthcare workers, fomites, and the hospital environment have been identified as possible sources of organisms associated with HAIs. Contaminated environmental surfaces and equipment, such as tables, chairs, floors, surgical tools, and stethoscopes, pose additional risks of transmission. The importance of proper environmental disinfection is challenging in veterinary hospitals as patients are not confined to their beds.

Antimicrobial resistance (AMR) is a significant and growing problem in veterinary medicine. AMR occurs when pathogens develop resistance to agents that were previously effective. Inappropriate antimicrobial administration and the transfer of resistant organisms between patients contribute to the development of AMR. A recent study found Enterococcus contamination in all 10 hospitals surveyed, with approximately 20% of isolates having AMR, including on 30% of stethoscopes.

The lack of surveillance and data on HAIs in veterinary practices contributes to the limited understanding of the problem. Surveillance is defined as the ongoing, systematic collection, analysis, and interpretation of health data, which is essential for planning and evaluating infection control programs. Without surveillance, practices may be unaware of the severity of their HAI problem and fail to take appropriate action. A surveillance program can help monitor specific outbreaks and establish a baseline threshold for HAI incidences, guiding risk mitigation strategies.

The implementation of infection control measures and programs is crucial to addressing HAIs in veterinary medicine. This includes hand hygiene, risk reduction, risk assessment, education, proper wound care, and the use of personal protective equipment. Emphasizing prevention and implementing control measures can improve the safety of patients, staff, and the broader community.
