Infection Control

COVID-19 infection typically presents with respiratory symptoms.

Infection is primarily spread from symptomatic people to others who are in close contact through respiratory droplets, like a cough or sneeze. Infection can also spread by direct contact with infected persons, or when a person comes in contact with contaminated objects and surfaces and then touches their eyes, nose, or mouth.

COVID-19 infection can be severe. The elderly population and those with underlying medical conditions are most vulnerable to the disease. However, for many, symptoms will be like those of the common cold or influenza. Eighty per cent of cases are mild to moderate and do not lead to hospitalization.

Common symptoms of COVID-19 include fever, cough, and shortness of breath. Sore throat, runny nose, fatigue, and a loss of smell and taste are also reported symptoms.

For detailed information about COVID-19 outbreaks in Ottawa healthcare institutions, please consult the Ottawa Public Health website.

Clostridium difficile is also known as C. difficile or “C. diff.” It is a bacteria commonly found in the environment, including in human and animal intestines and feces. Not normally dangerous, C. difficile can infect patients taking antibiotics, the elderly, and people with compromised health. Infection can cause diarrhea, fever, abdominal pain, and, in extreme cases, death.
The bacteria are spread through contact with contaminated surfaces, especially in washrooms, or with feces. The best prevention is good hygiene, including thorough washing of the hands.

For more information on C. difficile, please see the Province of Ontario fact sheet.

MRSA stands for methicillin-resistant Staphylococcus aureus. Staphylococcus aureus is a common bacterium or germ which commonly lives in the nose and on the skin. Most people who carry the Staphylococcus aureus bacterium do not have an infection. Sometimes people will develop infections with this bacterium and will require treatment. When the infection is in your blood, this is called bacteremia.

When common antibiotics such as penicillins are not able to destroy Staphylococcus aureus, the bacterium is called “resistant”, or in this case MRSA. Infections caused by MRSA are not necessarily more serious than infections caused by the regular Staphylococcus aureus bacterium. However, only a few antibiotics will treat MRSA infections.

MRSA is spread by direct contact with an infected person, their excretions, or with contaminated materials. The bacteria can live on hands or other surfaces, so the best prevention is good hygiene. Hands should be washed thoroughly with soap and water or with alcohol hand rub after using the bathroom or blowing your nose, and before touching wounds and dressings.

For more information on MRSA, please see the Province of Ontario fact sheet.

VRE stands for vancomycin-resistant enterococcus. Vancomycin is an antibiotic used to treat infections. Enterococcus is a common bacterium that is normally found in the lower intestine. Sometimes people develop infections with this bacterium and require treatment. Only a few antibiotics can effectively treat enterococcal infections, and one of them is vancomycin. If the enterococcus bacterium develops resistance to vancomycin (vancomycin-resistant enterococcus), the antibiotic vancomycin will not be able to destroy the bacteria. There are other antibiotics that will treat VRE infections, however.

VRE is usually spread on the hands of caregivers who have come in direct contact with an infected person. Excretions and feces are the most likely source of contamination. Without proper cleaning with disinfectants, VRE can survive for long periods on bathroom and hospital room surfaces. Thorough hand washing with soap and water or an alcohol rub is the best prevention against the spread of infection.

For more information on VRE, please see the Province of Ontario fact sheet.

A central line is a catheter inserted in a patient’s vein in order to supply them with blood, fluid replacement and/or nutrients. Central lines also let health care providers monitor fluids and make determinations about the heart and blood. CLI occurs when a central line becomes infected and bacteria spreads to the bloodstream.

CLI is more likely to occur in an intensive care unit (ICU) or with patients that have a serious underlying illness or debilitation, are receiving bone marrow or chemotherapy, or have a central line in for an extended period of time. Symptoms of CLI include redness, pain or swelling around the catheter site or pain or tenderness along the path of the catheter. There may also be fluid drainage from the skin around the catheter, and the patient may experience sudden fever or chills.

CLI is treated with antibiotics but the infections are preventable. Patients should wash their hands often with soap and water or alcohol-based rub and try not to touch their line or dressing. Health care providers or anyone else touching the line should wash their hands thoroughly

For more information on CLI, please see the Province of Ontario fact sheet.

Patients who need assistance breathing with a mechanical ventilator for more than 48 hours are at increased risk for developing pneumonia, a serious lung infection. Patients who are on a ventilator for more than five days, who are residents of a nursing home, or who have been hospitalized or have taken antibiotics within the last 90 days are at the greatest risk.

Symptoms of VAP include fever, low body temperature, foul smelling mucous or phlegm coughed up from the lungs or airway, and hypoxia, which is decreased oxygen levels in the blood.

VAP can be prevented through frequent hand washing using soap and water or an alcohol-based hand rub, by keeping the patient’s head elevated at 30 to 45 degrees, and by taking patients off mechanical ventilation as soon as possible.

For more information on VAP, please see the Province of Ontario fact sheet.

Research shows that hand hygiene is the single most effective way to reduce the risk of health care-associated infections. Alcohol-based hand rub is the preferred method for decontaminating hands when they are not visibly soiled. Hand washing with soap and running water is necessary when hands are visibly soiled.

Hand hygiene involves everyone in the hospital, including patients. Hand cleaning is one of the best ways you and your health care team can prevent the spread of many infections. Everyone, including visitors, should practice good hand hygiene before and after entering patient rooms.

Hand Hygiene Compliance Rates

The Heart Institute posts hand hygiene compliance rates quarterly, using the following formula:

(number of times hand hygiene performed) ÷ (number of observed hand hygiene indications) x 100 = % compliance

These percentages reflect:

These percentages reflect: 

1. Hand hygiene before initial patient/patient environment contact by health care provider type (i.e., nurses, physicians, allied health professionals, housekeeping, support staff, etc.). 
2. Hand hygiene after patient/patient environment contact by healthcare provider (i.e., nurses, physicians, allied health professionals, housekeeping, support staff etc.).

For more information on hand hygiene, please see the Province of Ontario fact sheet.

* Hand hygiene opportunity indicates a point in time at which hand hygiene should occur. The compliance rate of HH Performed divided by Observations is used as a standardized measure for comparison across healthcare facilities.

Research shows that that the use of checklists during surgical interventions can improve health outcomes for patients. These checklists and preoperative briefings have been shown to reduce preventable delays, improve operating room efficiency and create shorter wait times for patients with acute illnesses, lower nurse turnover rate and increase job satisfaction.

The Surgical Checklist encompasses three aspects:

• Briefing: The preoperative evaluation of the conscious patient prior to induction of the anesthesia with all members present.
• Time Out: The time out immediately prior to incision.
• Debriefing: The preparations for appropriate postoperative care prior to the patient leaving the operating room.

The Heart Institute posts surgical checklist compliance rates twice a year, using the following formula:

(number of times all three phases of the surgical safety checklist was performed) ÷ (total surgeries) x  100 = % compliance
