Avoiding Healthcare-Associated Infections (HAIs): Types & How to Avoid
Healthcare-associated infections (HAIs) are infections that are acquired by patients during the course of receiving medical treatment. These infections can occur in a variety of healthcare settings, including hospitals, long-term care facilities, outpatient clinics, and other settings. HAIs can have serious consequences, including prolonged hospital stays, increased healthcare costs, and, in severe cases, death. HAIs are caused by a wide range of pathogens, including bacteria, viruses, fungi, and parasites. They can be transmitted in several ways, including through direct contact with an infected patient or healthcare worker, contaminated medical devices or surfaces, and contaminated food or water. By working together, healthcare providers, patients, and their families can help to prevent HAIs and protect the health and well-being of patients receiving medical care.
What are Healthcare-associated Infections?
Healthcare-associated infections (HAIs) are infections that occur in patients receiving treatment for other conditions in healthcare settings, such as hospitals, nursing homes, and dialysis centers. These infections can be caused by a variety of pathogens, including bacteria, viruses, and fungi, and can range from minor skin infections to life-threatening conditions like sepsis. Some common types of HAIs include surgical site infections, urinary tract infections, and bloodstream infections. These infections can be transmitted through contact with contaminated surfaces, instruments, or healthcare workers, or exposure to contaminated bodily fluids. HAIs can have significant impacts on patient outcomes, including increased morbidity, mortality, and length of hospital stay. They can also lead to increased healthcare costs and decreased patient satisfaction. To reduce the risk of HAIs, healthcare facilities implement various infection control measures, including hand hygiene, use of personal protective equipment, proper cleaning and disinfection of equipment and surfaces, and following evidence-based guidelines for infection prevention and control. It is important to continue to monitor and study HAIs to improve prevention and control efforts and ensure the safe and effective delivery of healthcare.
How common is Healthcare-associated Infections?
Healthcare-associated infections (HAIs) are a common problem in healthcare facilities worldwide. The exact prevalence of HAIs is difficult to determine, as they often go underreported. However, it is estimated that approximately 1 in 31 hospital patients in the United States has at least one HAI on any given day.
The incidence of HAIs varies depending on the type of infection and the setting in which it occurs. For example, urinary tract infections and surgical site infections are among the most common types of HAIs, while Clostridioides difficile (C. difficile) infections and bloodstream infections are also common.
HAIs can have serious consequences for patients, including prolonged hospital stays, increased healthcare costs, and, in severe cases, death. It is estimated that HAIs add billions of dollars in healthcare costs each year, both in direct costs for treatment and indirect costs for lost productivity and decreased quality of life.
Due to the prevalence and consequences of HAIs, infection prevention, and control is a high priority for healthcare facilities worldwide. By implementing effective infection prevention and control measures and working to prevent the spread of infections, healthcare facilities can help to reduce the incidence of HAIs and improve patient outcomes.
Types of Healthcare-associated Infections
Healthcare-associated infections (HAIs) can be classified into several categories, including:
- Surgical site infections (SSIs). Infections occur at the site of a surgical incision.
- Urinary tract infections (UTIs). Infections occur in the urinary system, such as in the bladder, ureters, or kidneys.
- Bloodstream infections (BSIs). Infections that occur in the bloodstream, such as bacteremia or sepsis.
- Pneumonia. Infections occur in the lungs and are typically caused by bacteria, viruses, or fungi.
- Gastrointestinal infections. Infections that occur in the gastrointestinal tract, such as Clostridium difficile (C. diff) colitis or norovirus.
- Skin and soft tissue infections. Infections occur in the skin and underlying tissue, such as cellulitis or abscesses.
- Respiratory tract infections. Infections that occur in the respiratory system, such as influenza or pneumonia.
- Central nervous system infections. Infections that occur in the brain or spinal cord, such as meningitis.
By understanding the types of HAIs, healthcare facilities can develop targeted infection prevention and control strategies to reduce the risk of infection.
Risk Factors of Healthcare-associated Infections
Various factors can increase a patient's susceptibility to healthcare-associated infections (HAIs), including:
- Compromised immune system. Patients with weakened immune systems, such as those with HIV/AIDS, cancer, or receiving immunosuppressive drugs, are more susceptible to HAIs.
- Chronic medical conditions. Patients with chronic medical conditions, such as diabetes, liver disease, or lung disease, are more susceptible to HAIs.
- Advanced age. Older adults are more susceptible to HAIs due to a decline in immune function and an increased risk of underlying medical conditions.
- Length of hospital stay. The longer a patient stays in a healthcare facility, the greater the risk of acquiring an HAI.
- Invasive medical procedures. Patients undergoing invasive medical procedures, such as surgery, dialysis, or intubation, are at increased risk of HAIs.
- Antibiotic use. Overuse or improper use of antibiotics can increase the risk of HAIs by promoting the development of antibiotic-resistant organisms.
- Poor hygiene practices. Lack of hand hygiene by healthcare workers and inadequate cleaning and disinfection of equipment and surfaces can increase the risk of HAIs.
- Crowded living conditions. Patients in crowded living conditions, such as in long-term care facilities, are at higher risk of acquiring an HAI.
By identifying and addressing these factors, healthcare facilities can reduce the risk of HAIs and improve patient outcomes.
What Causes Healthcare-associated Infections?
Healthcare-associated infections (HAIs) are infections that occur as a result of receiving medical care. They can be caused by a variety of factors, including:
- Bacteria and viruses. Many HAIs are caused by bacteria and viruses that are present on a patient's skin, in the environment, or on medical equipment. Some common examples include Methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile (C. diff), and norovirus.
- Unsterile medical equipment. Using contaminated medical equipment, such as needles, catheters, and ventilators can also lead to the transmission of HAIs.
- Improper hand hygiene. Healthcare providers who don't properly clean their hands between patients can transfer bacteria and viruses from one patient to another.
- Antibiotic resistance. Overuse and inappropriate use of antibiotics can lead to the development of antibiotic-resistant bacteria, making it difficult to treat infections.
- Immune system suppression. Patients with weakened immune systems, such as those undergoing chemotherapy or with chronic illnesses, are at a higher risk for developing HAIs.
- Poor infection control practices. Lack of infection control measures, such as proper cleaning and disinfection of medical equipment and surfaces, can also contribute to the spread of HAIs.
What are the Symptoms of Healthcare-associated Infections?
The symptoms of healthcare-associated infections (HAIs) can vary depending on the type of infection, but common symptoms may include:
- Fever. A high body temperature can be a sign of an infection.
- Pain or redness at the site of the infection. Pain or redness in the area where a catheter or other medical device was inserted can be a sign of an HAI.
- Worsening of a pre-existing condition. A pre-existing condition, such as a wound or urinary tract infection, may worsen if an HAI develops.
- Nausea, vomiting, and diarrhea. Gastrointestinal infections, such as Clostridium difficile (C. diff), can cause these symptoms.
- Cough and shortness of breath. Respiratory infections, such as pneumonia, can cause these symptoms.
- Chills and body aches. An HAI can cause a general feeling of discomfort and flu-like symptoms.
How are Healthcare-associated Infections Diagnosed?
Healthcare-associated infections (HAIs) can be diagnosed through a combination of symptoms, medical history, and laboratory tests. The specific tests used to diagnose HAIs will depend on the type of infection and the suspected source of the infection. Here are some of the common tests used to diagnose HAIs:
- Physical examination. A physical examination can help identify signs of infection, such as redness, swelling, and warmth in the affected area.
- Blood tests. Blood tests can determine if there is an infection in the body and identify the type of pathogen causing the infection.
- Urine tests. Urine tests can be used to diagnose urinary tract infections and other types of infections in the urinary system.
- Stool tests. Stool tests can help diagnose gastrointestinal infections such as Clostridium difficile (C. diff) and norovirus.
- Sputum tests. Sputum tests can be used to diagnose respiratory infections such as pneumonia.
- Skin or wound cultures. Skin or wound cultures can help diagnose infections at the site of a wound or skin infection.
- Imaging tests. Imaging tests, such as X-rays, CT scans, and MRI scans, can help identify the source of infection and determine the extent of the infection.
The diagnosis of HAIs can be challenging and may require a combination of tests and a thorough evaluation of a person's medical history and symptoms.
What to Expect If you Get an Infection in Hospital?
If a patient acquires a healthcare-associated infection during their hospital stay, they can expect the following:
- Diagnosis and treatment. The patient's healthcare provider will diagnose the infection and determine the best course of treatment. This may involve taking antibiotics, antivirals, or antifungals, as appropriate, and may also involve removing any medical devices or lines that may be the source of the infection.
- Monitoring of symptoms. The patient's healthcare provider will monitor the patient's symptoms and check for any signs of the infection spreading. They will also monitor the patient's response to treatment and make any necessary adjustments.

If a patient acquires a healthcare-associated infection, they can expect to receive prompt and effective treatment, as well as ongoing monitoring and support, to help ensure their recovery. It is important to communicate regularly with the healthcare team and to follow their instructions and recommendations to help prevent the spread of the infection and ensure the best possible outcome.
How are Healthcare-associated Infections Treated?
Healthcare-associated infections (HAIs) can be treated with a variety of antibiotics and other medications, depending on the type and severity of the infection. Some common treatments for HAIs include:
- Antibiotics. Antibiotics are the most common treatment for HAIs and are used to target specific types of bacteria that are causing the infection.
- Antivirals. Antivirals are used to treat viral infections, such as hepatitis B or C, and can be effective in preventing the spread of the virus.
- Antifungals. Antifungals are used to treat fungal infections, such as Candida, and can help to prevent the spread of the infection.
- Antiparasitics. Antiparasitics are used to treat parasitic infections, such as those caused by helminths or protozoa, and can help to prevent the spread of the infection.
In addition to medication, other treatments for HAIs may include wound care, such as cleaning and dressing the affected area and removing any foreign objects that may be causing the infection. In severe cases, surgery may be necessary to remove infected tissue or foreign objects.
Prognosis of Healthcare-associated Infections
The prognosis of healthcare-associated infections (HAIs) depends on several factors, including the type of infection, the underlying health of the patient, and the promptness and effectiveness of treatment.
In general, HAIs can have serious consequences for patients, including prolonged hospital stays, increased healthcare costs, and, in severe cases, death. For example, patients with sepsis (a potentially life-threatening condition caused by a bacterial infection) have a higher risk of death compared to patients without sepsis.
However, many HAIs can be treated effectively with antibiotics, antivirals, or other medications. The prognosis for patients with HAIs can be improved through early diagnosis and prompt treatment, as well as effective infection prevention and control measures in the healthcare setting.
In some cases, patients may experience long-term consequences from an HAI, such as ongoing health problems or complications from the infection. Patients may also experience psychological effects, such as anxiety or depression, following an HAI.
Overall, the prognosis of HAIs can be improved through effective prevention and control measures and prompt, effective treatment. Patients and their families need to work closely with their healthcare providers to ensure the best possible outcome.
