16397 Avoiding Healthcare Associated Infections Hais

Overview

A healthcare-associated infection (HAI) is an infection that you catch while receiving medical care in a hospital, clinic, or other healthcare setting. You can get one during a stay, after a procedure, or even after you go home. These infections can happen when germs spread from hands, equipment, or surfaces. Many HAIs are preventable with simple safety steps.

Healthcare-associated infections are a known risk in hospitals worldwide. Thousands of people develop them each year, but hospitals have strong safety routines to reduce the risk. Being aware and asking questions can help keep you safer.

Anyone receiving healthcare can get an HAI, but people having surgery, people with weakened immune systems, older adults, premature babies, and people staying in intensive care are more likely to be affected.

Symptoms

Common symptoms

• Fever or chills
• Pain, redness, heat, or swelling around a wound or IV site
• Cough or shortness of breath
• Burning or pain when urinating
• Diarrhea or vomiting
• Feeling unusually tired or unwell

Symptoms in children

• Fever
• Irritability or drowsiness
• Poor feeding or dehydration
• Fast breathing or grunting
• Skin that is pale, blotchy, or has a rash

Symptoms in older adults

• Confusion or sudden changes in behaviour
• Falls or unsteadiness
• Loss of appetite
• Low body temperature
• Weakness or lethargy

Causes

Main causes

• Germs spread by hands of healthcare workers, patients, or visitors
• Contaminated medical equipment, devices, or surfaces
• Surgical wounds becoming infected
• Medical devices such as urinary catheters, IV lines, or breathing tubes
• Overuse of antibiotics, which can lead to drug-resistant germs

Risk factors

• Staying in hospital for a long time
• Having surgery
• Being in an intensive care unit
• Having a weakened immune system
• Living with a chronic illness like diabetes or kidney disease
• Being very young or very old
• Using broad-spectrum antibiotics for a long time

When to see a doctor

See a doctor urgently if:

• If you develop a fever, chills, or feeling very unwell within days of a healthcare visit or procedure
• If a surgical wound becomes increasingly painful, red, or drains fluid
• If you have trouble breathing or a persistent cough after being in hospital

Book a routine appointment if:

• If you have questions about how to care for a wound, catheter, or IV line
• If you notice mild redness at a procedure site but no fever or severe pain
• If you want a check-up after a recent hospital discharge

Diagnosis

A healthcare professional will ask about your symptoms, recent healthcare visits, and any procedures you had. They will examine you and may take samples from your blood, urine, wound, or sputum to check for germs.

Tests that may be done

• Blood tests
• Urine tests
• Swabs from a wound, nose, or throat
• Sputum (phlegm) cultures
• Chest X-ray or other imaging if needed

What to expect at your appointment

The care team will check for signs of infection and where it might be. They may start treatment before the test results come back, then adjust it later. Test results can take a few days. You will be told what to watch for and when to seek help.

Treatment

Treatment depends on the type and location of the infection. Mild infections may only need monitoring and self-care. More serious infections may need fluids, wound care, oxygen, or antimicrobial medicines such as antibiotics, antivirals, or antifungals. Your doctor will choose the safest and most effective approach for you.

Self-care at home

• Wash your hands often with soap and water or use hand sanitizer
• Rest and drink plenty of fluids
• Follow wound care instructions from your healthcare team
• Keep dressings clean and dry
• Monitor your temperature and report any changes

Medical treatments

Doctors may prescribe antimicrobial medicines to target the specific germ causing the infection. They may also drain an abscess or clean an infected wound. If the infection is linked to a catheter or IV line, that device may need to be removed or replaced. Always take your medicines exactly as directed and finish the full course.

When is surgery considered?

Some serious infections, such as an abscess or infected surgical site, may need a small surgical procedure to drain pus or remove dead tissue. This is usually done to help the infection heal faster and prevent it from spreading.

Living with this condition

During recovery, follow the care plan your healthcare team gives you. Go to follow-up appointments, take any medicines as prescribed, and write down any new symptoms so you can report them clearly.

Lifestyle tips

• Keep your hands clean and encourage visitors to do the same
• Get enough sleep to help your body heal
• Eat nourishing foods
• Avoid smoking and limit alcohol
• Stay in touch with your healthcare team if you have concerns

Diet and exercise

Eat a balanced diet with fruits, vegetables, lean protein, and whole grains. Drink enough fluids. Gentle movement like short walks can help you recover, but avoid heavy exercise until your doctor says it is safe.

Mental health and emotional wellbeing

Catching an infection during healthcare can feel frightening and stressful. It is normal to feel anxious, frustrated, or low. Talk to your care team about how you are feeling. They can connect you with psychological support services if needed.

Prevention

Many healthcare-associated infections can be prevented. Hospitals use strict hygiene routines, sterilise equipment, and carefully manage antibiotics. You can help by washing your hands, asking care providers if they have cleaned their hands, and following all infection prevention instructions.

Vaccines

Staying up to date with recommended vaccinations can lower your risk of some infections. Ask your healthcare provider which vaccines are right for you before a planned hospital stay or procedure.

Screening programmes

Some healthcare facilities screen patients for resistant germs before admission or before surgery. You may be tested with a simple swab so the team can take extra precautions if needed.

Complications

If left untreated

• The infection may spread to the bloodstream, causing sepsis
• Wounds may heal slowly or break down
• Organ damage can occur
• Longer hospital stays and more complex treatment may be needed
• Antibiotic resistance can make future infections harder to treat

Long-term outlook

Most healthcare-associated infections can be successfully treated, especially when they are caught early. Hospitals are committed to reducing these infections, and many people recover fully. With the right treatment and support, the outlook is good.
