Infection control care bundles


Care bundles is an effective way of preventing healthcare associated bundles (HAI) amongst high risk patients. A ‘bundle’ is a set of practices that, when performed collectively, reliably and continuously, have been proven to improve patient outcomes. While there are care bundles for various clinical care processes, it is very popularly used in prevention of HAIs. Care bundles for preventing common HAIs are given below (Reference – WHO and CDC guidelines)


Ventilator Bundle for prevention of Ventilator Associated Pneumonia

1.       Elevation of the head of the bed: Elevation of the head of the bed has been found to be correlated with reduction in the rate of ventilator-associated pneumonia. The recommended elevation is 30 degrees. Head elevation must be ensured for every patient on Ventilator on daily basis
2.       Daily sedative interruption and daily assessment of readiness to extubate: Reducing sedation decreases the amount of time spent on mechanical ventilation and therefore the risk of ventilator-acquired pneumonia is decreased. In addition, weaning patients from ventilators becomes easier when patients are able to assist themselves at extubation with coughing and control of secretions.
3.       Peptic Ulcer Disease Prophylaxis: Stress ulcerations are the most common cause of gastrointestinal bleeding in intensive care unit patients, and the presence of gastrointestinal bleeding due to these lesions is associated with a five-fold increase in mortality compared to ICU patients without bleeding. Applying peptic ulcer disease prophylaxis is therefore a necessary intervention in critically ill patients
4.       Deep Venous Thrombosis Prophylaxis: There is a higher incidence of deep venous thrombosis in critical illness. Deep venous thrombosis prophylaxis is applied in all patients on ventilator
5.       Daily oral care with chlorhexidine: The recommended chlorhexidine solution strength is 0.12%. Dental plaque bio films are colonized by respiratory pathogens in mechanically ventilated patients. Dental plaque develops in patients that are mechanically ventilated because of the lack of mechanical chewing and the absence of saliva, which minimizes the development of bio film on the teeth. Dental plaque can be a significant reservoir for potential respiratory pathogens that cause ventilator-associated pneumonia (VAP). Use of Chlorhexidine antiseptic acts as an inhibitor of dental plaque formation and gingivitis

Central Line Bundle for prevention of catheter associated blood stream infections

1.       Hand Hygiene: Washing hands or using an alcohol-based waterless hand cleaner helps to prevent contamination of central line sites and bloodstream infections
2.       Maximal Barrier Precautions Upon Insertion: For the staff placing the central line and for those assisting in the procedure, maximal barrier precautions means strict compliance with hand washing, wearing a cap, mask, sterile gown and gloves. The cap should cover all hair and the mask should cover the nose and mouth tightly. These precautions are the same as for any other surgical procedure that carries a risk of infection. For the patient, maximal barrier precautions means covering the patient from head to toe with a sterile drape with a small opening for the site of insertion
3.       Daily Review of Line Necessity with Prompt Removal of Unnecessary Lines: Daily review of central line necessity will prevent unnecessary delays in removing lines that are no longer clearly necessary in the care of the patient

Urinary Catheter Bundle for prevention of catheter associated urinary tract infections

1.       Assessment of the requirement for continuing catheterization: Check the clinical condition, if urinary catheter is still required. If there are no indications, then catheter should be removed
2.       Checking whether the catheter has been continuously connected to the drainage system: Urinary catheter must be continuously connected to the drainage bag
3.       Daily meatal hygiene: Routine daily meatal hygiene is performed
4.       Urobag is regularly emptied in a clean container: The urinary catheter bag should be emptied regularly, as a separate procedure into a clean container
5.       Hand hygiene is performed prior to and after each catheter care procedure: Decontaminate hands (soap or hand rub) before accessing the catheter drainage system, after glove removal following access to the catheter drainage system.

Surgical care bundle for prevention of surgical site infections

1.       Prophylactic antibiotic: Correct antibiotic prophylaxis given at correct time and discontinued at correct time significantly reduces the chance of infections at surgical site
2.       No hair shaving: Hair shaving of the surgical site increases risk of infection. Instead hair clipping shall be performed
3.       Glucose control (peri-operative): Glucose must be kept under control limit to prevent SSI
4.       Normothermia (except cardiac surgery): Normothermia is keeping the condition of normal body temperature. The post-surgery patients must be kept in an environment with normal temperature that does not cause increase or decrease in activity of body cells
5.       Pre-op screening for S. aureus or MRSA – If found positive the organism must be decolonized first before operating
