What is the Full Form of CSSD

CSSD: Central Sterile Supply Department

CSSD stands for Central Sterile Supply Department. There has been increased interest in planning sterilizations during the past few years. A hospital's central sterile supply department (CSSD) is a service division that manages the distribution of sterile supplies to all hospital departments. According to Bhattacharjee's description, it can be summarized as the hospital service that provides sterile supplies to all departments, including general wards, OPDs, and specialist units. To prevent hospital-acquired infections (HAI), CSSD aims to supply all hospital departments with equipment guaranteed to be sterile and ready for use in patient care.

The CSSD should be a separate department with receiving, cleaning, packing, disinfecting, and sterilizing facilities. Instruments should be distributed and stored according to established methods. Correct design, adequate equipment, skilled workers, and good workflow are critical components of this area. The term CSSD was first used by the American College of Surgeons in 1928, marking the beginning of CSSD history. In the United Kingdom, Regular CSSD was developed in 1955 by the Cambridge Military Hospital. In India, the first CSSD was established in 1965 by Safdarjung Hospital in New Delhi.

The central sterile services department (CSSD), also referred to as the sterile processing department (SPD), sterile processing, central supply department (CSD), or central supply, is an integrated area in hospitals and other healthcare facilities that performs sterilization and other actions on medical consumables, equipment, and supplies for later use by healthcare professionals in the operating room of the hospital as well as for other uses like aseptic procedures which includes catheterization, wound care, and other aseptic procedures.

The CSSD is essential for improving patient safety and lowering hospital surgical infection rates. It is crucial to ensure that surgical equipment is properly disinfected from an infection control standpoint. If surgical equipment is microbially contaminated, there is a higher chance that the surgical wound will become contaminated and infected as a result. As a result, one of the fundamental and effective ways to prevent surgical site infection is to sterilize surgical tools (SSI) properly.

Numerous hospital departments depend on the CSSD's services. The task of sterilizing and preparing medical and surgical supplies and equipment for use in patient care falls within the purview of the Sterile Supply Department. Maintaining consistently high standards for sterilization procedures and product quality is crucial because all goods are now pre-infected, cleaned, packed, and sterilized in one department. Efficient processing is crucial for effectiveness, economy, and patient safety, given the growth in the quantity and variety of surgical procedures and medical devices.

We could improve patient and employee safety by implementing cutting-edge technologies and procedures.

We must overcome significant obstacles to copy or replicate best practices in the sterilization process. We should set up systems to support and guarantee the proper handling of surgical tools during and after the operation. Digital tools supporting CSSD procedures make managing and documenting data easy. Digital technologies also make it possible to update data instantly and communicate information more effectively. With the help of these solutions, CSSD employees may make fewer mistakes, experience less pressure, and adhere to policies and rules more easily.

A high standard in the CSSD, the "backbone" of sterile practice in any hospital, is maintained by upgrading the quality management with the most recent advancements.

The department's goals are to provide sterilized material from a central location, department where sterilizing procedures are carried out in controlled environments, helping to lower the frequency of hospital infections.


Cleaning, disinfecting, and sterilizing reusable medical equipment are often the functions of a sterile services department. Reusable medical equipment, or RME, can include any medical device, including IV pumps, crash carts, and surgical instruments made of stainless steel. RME is divided into three classes of data categories which are non-critical, semi-critical, and critical, each requiring a certain amount of reprocessing.

Non-critical devices like IV poles and pumps need to be disinfected at least to an intermediate degree, which can be done using the majority of hospital disinfectants. Semi-critical goods, which typically include endoscopes like those used in colonoscopies, are anticipated to come into touch with an intact mucous membrane. These goods require high-level disinfectants like hydrogen peroxide plasma, peracetic acid, or glutaraldehyde solution.

Sterilization is necessary for critical things, such as equipment inserted into a patient's bloodstream or a sterile body portion.

Use of Sterilization Techniques

The primary task is sterilization, which eliminates all living things from an item of the cleanest services divisions. In a separate decontamination chamber, the items that they will sterilize must first be cleaned, and they must then examine them for efficacy, cleanliness, and damage. There are various sterilization techniques, and the choice of which to use depends on various criteria, including operational costs, potential worker dangers, effectiveness, timing, and the nature of the materials to be sterilized.

Steam sterilization is one of the most affordable and simple techniques used in the US. Instrument trays and packages are put in a steam-filled room with a temperature of 250-270 °F (121-132 °C), which effectively destroys all microorganisms.

Ethylene oxide (ETO) gas can also be used to sterilize things. This procedure, developed by the US military in the 1950s, is used on objects that cannot withstand extremely high temperatures sterilization with steam. They developed alternative approaches in the 1990s since ETO sterilization is dangerous to employees and takes much longer than steam sterilization. Today, the most popular sterilization technique at low temperatures is hydrogen peroxide plasma, which poses almost no risk to the workers and requires fewer cycles than ETO sterilization.

Depending on the institution, a hospital's sterile storage policy may be an event or time-related. If the policy is event-related, the package is considered sterile until an incident that endangers its sterility occurs (e.g., opened, dropped the package, high humidity conditions, etc). If the healthcare facility's policy is time-related, an expiration date is added to the package before supplying it to the end user as a sterile product. The sealed package must be returned to the supplier if it was broken or opened by a health worker along the supply route CSSD to re-sterilize.

The most important sterilization stage is decontamination, which starts with point-of-use cleaning in the operating room. A gadget's sterilization will only occur if it is cleaned properly. Cleaning procedures must follow the manufacturer's instructions for use (IFUs). Each thing processed must adhere to these. Having a well-operating decontamination area depends on several things, including the following:

  • Because lumens are a major concern, we must properly dilute detergents to prevent instrument rusting and staining an array of brushes with different lengths and diameters to thoroughly clean inside lumened instruments.
  • SPD staff needs to be knowledgeable about how to use all processing equipment.
  • Regular and carried out by the manufacturer's representative monthly in-service is advised.
  • To ensure the equipment is operating as intended, effectiveness testing should be carried out and documented.

Technician for Sterile Processing

Surgical instruments and other medical supplies are cleaned and sterilized by sterile processing technicians so they can be safely distributed and used on new patients. The medical facility's special department typically houses all of this work including the following job titles:

  • Technician for sterile processing and distribution (SPD tech or CPD tech)
  • Sterile Science Associate (SSA)
  • Degree Sterile Scientist (SS)
  • Degree Central Sterile Supply Technician (CSS tech)
  • Central Processing Technician (CPT)
  • Central Service Technician (CST)
  • Certified Sterile Science Technician (CSST)
  • Degree in Master of Sterile Sciences (MSS)


Decontamination, assembly and sterile processing, sterile storage, and distribution are the four main divisions into which sterile processing departments are normally organized.

  • Used surgical tools and other medical devices are disassembled and cleaned.
  • Operating and maintaining specialized decontamination types of machinery, such as ultrasonic cleaners and automatic washers/disinfectants
  • Checking the cleanliness of decontaminated objects.
  • Assembly
  • Protect yourself from getting hazardous bacteria by using PPE.

Storage and Sterilization

  • Instrument assembly and packaging after cleaning and decontamination.
  • Sterilizing instrument trays that have been assembled in the proper sterilizers
  • Operating and keeping an eye on delicate sterilizing machinery, such as autoclaves
  • For future tracking of the things that have been sterilized and stored, full records of the number of items that have been sterilized, including Autoclave cycle numbers, lot/batch numbers, and expiration dates, should be kept.


  • Replenishing crash carts.
  • Coordinating sterile medical equipment.
  • Ensuring the viability of sterile supplies and avoiding sterility problems associated with events.
  • Delivering sterile supplies to the appropriate locations and collecting used supplies

Goals of CSSD

  1. To deliver sterilized items from a central location where sterilization procedures are carried out in a controlled environment, helping to lower the frequency of hospital infections.
  2. Keep track of the performance of the cleaning, disinfection, and sterilization process.
  3. To keep an eye on and execute the infection control policy-required controls to stop cross-infection.
  4. To keep track of goods and tools in inventory.
  5. To keep abreast of industry advancements for effectiveness, economy, accuracy, and provision to give patients and employees a safe atmosphere.
  6. To provide better patient care.

Process in CSSD

CSSD Full Form


A CSSD assistant receives non-sterile materials from various hospital departments, examines them, and keeps track of their state. After receiving the instruments, they are separated and checked for damage. The instruments are sent for repair or discarded as necessary if they are damaged.


This function involves cleaning used instruments and procedure sets (such as cut-down sets, tracheostomy sets, lumber puncture sets, sterna puncture sets, aspiration sets, catheterization sets, suturing sets, dressing sets, etc.) using either a manual cleaning process or an ultrasonic cleaning system.

  1. Pre-cleaning room: All instruments are thoroughly washed with simple water in this chamber to eliminate any visible particles.
  2. Disinfection chamber: Soiled instruments are decontaminated in this chamber using water and savlon solution.
  3. Ultrasonic Chamber: Tools are cleaned in this chamber using a 1% multi-enzyme cleaning solution.
  4. Rinsing Chamber: Instruments are rinsed in this compartment with simple water.
  5. Drying chamber: All cleaned objects are dried in this chamber using a drier for 15 minutes at a temperature of 60 °C.

Workflow in CSSD

Area for Assembly and Packaging

After washing and drying, all the instruments are put together and sealed either manually or by a machine. All of the packs have labels and autoclave indicator tapes attached.

CSSD Full Form

A Field for Autoclaving

In this area, many types of sterilizing devices are used, three gravity displacement autoclaves and two vacuum-assisted autoclaves. The packs are put into the autoclave machine, which runs for 30 minutes at the prescribed temperature and pressure (121 c and 20 psi, respectively). After the packs have been sterilized, the sterilizing units are shut off, and the autoclave indicators are examined to ensure that the packs have been sufficiently sterilized. If necessary, the sterilization procedure is then repeated. If a material successfully kills 99.99% of bacterial spores, it is declared sterile. We must repeat the entire process if the sterile packs are torn, opened, damp, etc. Packs that have been sterilized sufficiently are kept in the sterile storage area.

Sterile Storage Area

Sterilized things are stored here, and some items we can't distribute on the same day are held in an ultraviolet storage cabinet.

Issuing Window

After entering the relevant issuing register, all sterile supplies and other things are distributed to the departments involved from a separate window.

CSSD's Monitoring Protocol

  1. Each cycle's temperature, pressure, and time are recorded and observed following accepted guidelines.
  2. Various quality indicators are used to assess sterilization effectiveness, including:
  3. Exposure control measures: All packs intended for autoclave storage have to have autoclave indicator tape with the date of sterilization adhered to it.
  4. Load control: All autoclave machines use rapid biological indicators twice a week for the first load. If the result is positive, it signifies that sterilization has occurred, and if the result is negative, it means that sterilization has not occurred. It is insufficient that the entire load is re-autoclaved.
  5. A wet pack cannot be considered sterile. Even if the indications indicate the necessary modifications, these are repacked and re-sterilized.
  6. Different trolleys are available to transport sterile and non-sterile instruments.
  7. Only employees who are on duty are permitted in the sterile storage room.

Keeping Records

  1. All items are entered into the CSSD receipt register, including the date, time, type of instruments in the pack, department name, and name and the item's recipient's signature.
  2. Culture reports and records of all indicator tests are kept.

Maintenance of Equipment

Equipment upkeep is carried out following AMC and warranty. The logbook or register is where all the information is kept.

Recall Procedure

  1. If any monitoring signs are ineffective, the CSSD supervisor should be notified right away.
  2. CSSD staff members should work to identify the root cause of the issue and make plans for a solution.
  3. After reprocessing and verifying its sterility, we should provide the item.

Performance Review

Based on pertinent records and statistical indices about quality, productivity, material consumption, etc., performance evaluation is conducted. Internal quality audits are routinely performed monthly to evaluate the system's effectiveness, and performance records and on-site inspections are used. The comments obtained from such evaluations are noted and used to enhance quality-related actions in the future.
