The document outlines the structure and processes of a Central Sterile Supply Department (CSSD) in a hospital, detailing its aim to provide sterile supplies and reduce infection rates. It describes the layout, equipment, staffing, and sterilization methods utilized to ensure an efficient and quality supply of sterile materials. Furthermore, it emphasizes the importance of quality control and proper management of sterilization processes to maintain safety and compliance within the hospital environment.

2. Definition
“as that service, with in the hospital, catering
for the sterile supplies to all departments ,
both to specialized units as well as general
wards and OPDs.”

3. AIM
• Centralizing the activities of receipt, cleaning, assembly,
sterilization, storage and distribution of sterilized materials
from a central department where safe sterilization is done under
controlled conditions with adequate managerial and technical
supervision at an optimum cost.
• To provide an efficient, economic, continuous and quality supply
of sterilized material to various areas of the hospital to deliver
quality and infection free patient care.
• Contributes to reduction in hospital infection rate
• To reduce the burden of work of the nursing personnel, there by
enabling them to devote more of their time to patient care .

6. PLANNING OF CSSD
The CSSD can broadly be classified into two parts
Central
unit
Peripheral
unit
-Responsible for receiving dirty
Utilities cleaning, processing,
Sterilization, storage and supply
- Mainly responsible for distribution
to various areas of hospital.
- TSSU (Theater Sterile Supply Unit)

9. LAY OUT DESIGNING PRINCIPLE
 There is no back tracking of sterile goods.
 One way movement from receiving counter to issue counter.
 Sterile area should be prior to sterile storage and issue.
 The receiving counter must be away from the issue counter.
 Separate receiving and issuing counter
There should minimum six basic division in CSSD

10. STRUCTURAL DESIGNING
The Central Unit comprises of three zones, separated by two distinct
barriers.
One collection window
one supply window on the other end.

17. STERILIZATION .
 It is a process of freeing an article from all living
organisms including bacteria ,fungal spores and
viruses.
 A material is pronounced sterile if it
achieves 99.99% kill of bacterial spores.

18. METHODS OF
STERILIZATION
NATURAL

20. 1.Indicator tapes
• Time, temperature, pressure sensitive tapes.
• Does not indicate for sensitivity for sterilization but only suggest the required
time and pressure the items have been subjected
2.Bacteriological indicator :
• Kept in center of pack before the process and later on subjected to lab for
colony count and growth
• A pack of non- pathogenic bacterial spore (stearo- thermopiles) is placed in
each load to check quality.
• If the level of sterilization is satisfactory, the green/ brown color change to black.
3.Personnel should be adequately trained to handle the equipments.
4.Regular maintenance of equipments be done.
5.The hospital infection control committee monitors the sterilization by drawing
samples and growing in medias for colony count.
QUALITY CONTROL

21. STORAGE
• After sterilization the sterilized items are kept in different racks as
per labeling.
• Supplied as per the demand of different area.
• To ensure continuous availability of sterile supply five times of
daily requirement should be available in storage.
