Hospital-acquired infections, also known as healthcare-associated infections (HAIs), are a significant problem in the healthcare industry. HAIs are a leading cause of morbidity and mortality, resulting in extended hospital stays and billions of dollars in additional healthcare costs annually. While exact data is lacking, it is estimated that millions of HAIs occur in the USA each year, with a 2002 study estimating 1.7 million cases. HAIs include a range of infections such as central line-associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), surgical site infections (SSI), hospital-acquired pneumonia (HAP), and Clostridium difficile infections. The CDC's National Healthcare Safety Network (NHSN) closely monitors these infections, with approximately 1 in 31 hospital patients affected on any given day.

What You'll Learn
Surgical site infections (SSIs)
SSIs are caused by germs, including bacteria such as Staphylococcus, Streptococcus, and Pseudomonas. These germs can infect surgical wounds through physical contact with a contaminated caregiver or surgical instrument, through germs in the air, or via germs already present on/in the patient's body.
The incidence of SSIs can be as high as 20%, depending on the specific surgery, surveillance criteria, and data collection quality. They are a significant clinical problem, contributing to mortality and morbidity, and placing a burden on healthcare resources.
To reduce the risk of SSIs, the CDC emphasizes the importance of good patient preparation, aseptic practices, attention to surgical technique, and antimicrobial prophylaxis in specific circumstances. Additionally, emerging technologies, such as microbial sealants, can be used to immobilize skin flora during surgery.
Regarding the overall prevalence of HAIs, on any given day, about one in 31 hospital patients has at least one healthcare-associated infection. In 2015, there were an estimated 687,000 HAIs in U.S. acute care hospitals, resulting in approximately 72,000 deaths. While exact data is lacking, it is estimated that approximately 2 million HAIs occur annually in the USA.

Catheter-associated urinary tract infections (CAUTIs)
CAUTIs are a major health concern due to their frequent recurrence and potential complications. When a CAUTI becomes symptomatic, the resulting sequelae can range from mild symptoms such as fever, urethritis, and cystitis, to more severe complications like acute pyelonephritis, renal scarring, calculus formation, and bacteremia. If left untreated, CAUTIs can lead to urosepsis and even death.
The risk of developing a CAUTI is heightened by prolonged catheter use. It is estimated that 15-25% of hospitalized patients use urinary catheters, with catheterization rates of 3-10% per day. A study of 1,540 nursing home residents found that catheterized residents had a three times higher risk of hospitalization, longer hospital stays, and longer antibiotic therapy compared to non-catheterized residents.
CAUTIs can be prevented by limiting catheter usage and ensuring proper catheter handling by healthcare professionals. Most CAUTIs can be treated with antibiotics and/or the removal or change of the catheter. However, it is important to note that asymptomatic CAUTIs typically do not require antimicrobial treatment, as this may lead to the development of antibiotic-resistant organisms.

Central line-associated bloodstream infections (CLABSIs)
CLABSIs are defined as the recovery of a pathogen from a blood culture in a patient with a central line at the time of infection or within 48 hours before the infection's development. They are preventable through proper aseptic techniques, surveillance, and management strategies. Hand hygiene, sterile central line insertions, and timely removal of central lines are crucial for prevention. Healthcare institutions aim for zero infections and employ best practices, protocols, and checklists to ensure patient safety.
The Centers for Disease Control and Prevention (CDC) provides annual National and State Healthcare-Associated Infections Progress Reports, tracking CLABSIs and other HAIs. The reports compare infection rates and device utilization over time, with lower Standardized Infection Ratios (SIRs) and Standardized Utilization Ratios (SURs) indicating better performance. The National Healthcare Safety Network (NHSN) is a widely used HAI tracking system that helps identify problem areas and measure progress in prevention efforts.
CLABSI prevention is a collaborative effort involving healthcare workers, patients, and families. Healthcare workers follow guidelines for central line insertion and maintenance, while patients and families are educated on hand hygiene and central line care. Initiatives like the Maryland Patient Safety Institute's On the CUSP Project have successfully reduced CLABSI rates, demonstrating the effectiveness of safety programs in improving patient outcomes.
HAIs, including CLABSIs, are a significant issue in healthcare, causing morbidity, mortality, extended hospital stays, and increased costs. While exact data is lacking, it is estimated that approximately 2 million HAIs occur annually in the USA, emphasizing the need for preventive measures and resources to address this problem.

Clostridioides difficile (C. diff)
Clostridioides difficile, commonly known as C. diff, is a bacterium that causes diarrhoea and colitis (an inflammation of the colon). It is a significant healthcare-associated infection (HAI) that affects patients in hospitals, long-term care facilities, and communities. C. diff infections are a leading cause of morbidity and mortality in the United States, contributing to increased hospital stays and healthcare costs.
C. diff bacteria typically reside harmlessly in the human bowel alongside other bacteria. However, when an individual takes antibiotics, the balance of bacteria in the bowel can be disrupted, leading to a C. diff infection. This infection can have severe consequences, including sepsis, and is estimated to affect almost half a million people in the United States annually.
C. diff infections are more prevalent among patients in healthcare settings, as individuals carrying the bacteria often receive treatment or reside in these facilities. The bacteria spread through person-to-person contact via faecal matter, and the germs can remain active for extended periods outside the body, forming spores that can survive on surfaces and in the environment for months or years. These spores can be ingested and cause infection when they reach the intestines, particularly in individuals with weakened immune systems or those who have recently taken antibiotics.
The good news is that C. diff infections are preventable and treatable. To prevent C. diff infections, maintaining a healthy microbiome is essential. Antibiotics can disrupt the balance of bacteria in the digestive tract, making individuals more susceptible to C. diff. Therefore, it is crucial to use antibiotics judiciously and only when necessary. Additionally, practising good hygiene and taking precautions, such as staying at home when experiencing diarrhoea, are essential to prevent the spread of C. diff infections.
When a C. diff infection occurs, it can usually be treated with a different type of antibiotic. Treatment may involve stopping the current course of antibiotics, if possible, and starting a new 10-day course of antibiotics specifically targeted at treating C. diff. In some cases, a faecal microbiota transplant may be recommended if the infection recurs multiple times. This procedure involves introducing bacteria from a healthy individual's faecal matter into the patient's gut to help stop the infection. Adhering to the prescribed treatment plan is crucial to ensure the infection clears up completely and prevent a relapse.

Methicillin-resistant Staphylococcus aureus (MRSA)
In the United States, around 2 million patients acquire hospital-associated infections (HAIs) each year. HAIs are a leading cause of morbidity and mortality, resulting in extended hospital stays and $17 to $20 billion in additional healthcare costs annually.
MRSA infections frequently occur in healthcare settings such as hospitals, nursing homes, and other healthcare facilities, but they can also spread in the community. Hospitalized individuals, particularly the elderly, are susceptible to MRSA due to their weakened immune systems. Surgical site infections are a common mode of transmission, and these infections can spread from the skin to internal organs and the bloodstream. Healthcare providers can inadvertently contribute to the spread by neglecting proper hand hygiene between patient examinations.
MRSA prevention and control are crucial. Healthcare providers play a vital role in diagnosing and treating MRSA infections. Laboratory tests, such as the rapid latex agglutination test, can detect specific proteins associated with MRSA. While MRSA is resistant to many antibiotics, treatments do exist, including antibiotics like vancomycin and teicoplanin, which are administered intravenously. Surgery may also be required to drain infected areas. Efforts to prevent and slow the spread of MRSA include tracking infections through surveillance systems and working closely with health departments, agencies, healthcare providers, and patients.
In summary, Methicillin-resistant Staphylococcus aureus (MRSA) is a significant healthcare concern due to its resistance to antibiotics and its ability to cause severe infections, particularly in healthcare settings. The prevention, control, and treatment of MRSA are essential to reducing its impact on public health.
