It may not always be about what we know, but it’s always about how much we care.
CENTRAL STERILE SUPPLY DEPARTMENT (CSSD)
The Central Sterile Supply Department (CSSD) is responsible for delivering sterile supplies of surgical instruments, linen, dressing material and other reusable devices to clinical areas like operation theatres, specialty units such as bone marrow transplantation units (BMT), wards, day care units, and out-patient clinics so that procedures can be conducted with safe, contamination-free medical devices and consumables. The defining feature of the CSSD at Tata Medical Center is the presence of modern, world class equipment infrastructure and a team of professional & dedicated personnel. The department is committed to maintain a high level of standards with respect to QA/QC (quality assurance and quality control) activities which involve monitoring the processes through physical, chemical, and biological indicators, and other process challenge devices. The overall vision is to deliver quality in all deliverables of the CSSD, not just sterile supplies.
The services of CSSD includes collecting, sorting, cleaning, disinfecting, drying and assembling instruments; preparation of linen items; packaging, sterilizing, storing and issuing sterilised trays and boxes; quality monitoring, and record keeping.
Central Sterile Supply Department (CSSD) at Tata Medical Centre – Kolkata is committed to the efficiency, economy & uniformity of sterile supply for the care of all patients with aseptic techniques. The main aim is to supply the sterile medical devices to the clinical areas at right time, right place and right condition.
The CSSD is located on the 2nd floor of the Main Hospital building, at the distal end of the Operation Theatre Complex. The operations of CSSD are spread across an area of approximately 3000 square feet.
