Disinfection of Patient Care Equipment Sr. Elinore Matiga

1. Cleaning & Disinfection of
Patient Care Equipment
Elinore Matiga

2. DEFINITIONS:
A. Cleaning – The physical removal of foreign material.
e.g. dust, oil, organic material such as blood,
secretions, excretions and micro-organisms.
B. Disinfection – A process that eliminates many or all
pathogenic microorganisms with the exception of
bacterial spores from inanimate objects. This is
generally accomplished by the use of liquid
chemicals ..

3. Cont…..
C. Sterilization- The complete elimination or
destruction of all forms of microbial life.
It is accomplished in the hospital by either physical
or chemical processes. Steam under pressure,
dry heat, low temperature sterilization processes
(plasma sterilization), and liquid chemicals are
principal sterilizing agents used in the hospital.

4. Cont….
D. Non-Critical Equipment – Those items that
either touch only intact skin (but not mucous
membranes )or do not directly touch the
patient.
E. Personal Protective Equipment (PPE) – Equipment
to be worn if hazardous situations. PPE will either
prevent or reduce the severity of an injury
should an accident occur. PPE can include, but
is not limited to: Safety Goggles, Respirators,
Gloves, Protective Gowns, face shield.

5. PURPOSE:
The overall goal of infection prevention
practices is to eliminate the risk of the
transmission of pathogens between
patients and between patients and the
health care worker.

6. POLICY:
1)Critical medical and surgical devices
and instruments that enter normally
sterile tissue or the vascular system or
through which a sterile body fluid flows
(e.g., blood) are sterilized before use on
each patient.

8. Cont….
3) Noncritical patient-care surfaces / equipment
(e.g., bedrails, over-the-bed table)
and equipment (e.g., blood pressure cuff)
that touch intact skin receive low-level
disinfection with a hospital-grade
disinfectant before us on each patient,
e.g., surfaces that come into contact only with
intact skin, but could be contaminated with
body secretions,
e.g. stethoscopes, blood pressure cuffs, splints.

10. RESPONSIBILITIES:
Cleaning is a shared
responsibility between the
NURSING and HOUSEKEEPING
departments.

11. PROTECTIVE BARRIERS:
1. Disposable gloves. Gloves must be changed as
required, i.e., when torn, when hands become
wet inside the glove or when moving between
patient rooms.
2. Household gloves can be worn, but they must be
discarded when the cleaning is complete.
3. Protective Eye wear (goggles, face shield or mask
with eye protection)
4. Masks (surgical or procedural masks sufficient)
5. Gowns

13. Disinfectant Solutions Used for
Low-Level Disinfection include:
1. Alcohol (Isopropyl alcohol 70%(Ultrafast)
2. SURFA’SAFE
3. Quaternary Ammonium Compounds (S.S.D.D.-50)
The concentration and contact time for each product
will differ. For that reason it is important to read the
product label prior to commencing any cleaning
and disinfection process.

16. RECOMMENDED PROCEDURES FOR CLEANING AND
DISINFECTION OF PATIENT CARE EQUIPMENT
1. Gather all equipment, cleaning solutions and materials
to clean the patient care devices.
2. WASH hands and put gloves prior to cleaning the
devices. Personal protective equipment should be
changed if torn or soiled.
3. Visible or gross soil present and/or blood or body
fluid spills must be removed prior to cleaning.
[See Protocol for Cleaning & Disinfecting a Blood or Body Fluid spill.]

17. Cont…
4. As appropriate, clean all surfaces of the
patient care equipment or devices using
a detergent or enzymatic solution. When
appropriate, dismantle the devices
to ensure that all surfaces can be cleaned.
To ensure that cross contamination does
not occur use clean cloths for each device
to be cleaned.

19. Cont…
6. If using a 1‐Step Cleaning‐Disinfecting
Solution a separate cleaning step is not
necessary unless the surfaces are visibly
soiled. To ensure disinfection occurs,
the cleaner‐disinfectant solution may need
to be applied multiple times in order to
achieve the contact time as specified on the
product label.

20. Cont..
7. Soiled rags should be placed in a bag for
laundering. Disposable cloths should
disposed as regular waste in garbage bags.
8. Remove and discard gloves, PPE.
WASH HANDS.
