The BackBone's Central Sterile Services Department (Sterile Supply) module's main function is to manage the use of sterile items, linen, and medical equipment on the wards and Operating Theaters. The Central Sterile Services Department (CSSD) usually receives reusable equipment, linen from various wards and Operating Theaters for sterilization. Items are exchanged depending upon the requirements of the patients, departments and theaters. For example, the Sterile Supply module would coordinate the use of linen in a hospital by synchronizing the following actions: dirty linen is sent for washing to the laundry, washed linen from laundry is sent to CSSD for sterilization, the sterilized linens are then issued to wards/Operating Theaters when requested.

The Sterile Supply module also catalogues and tracks the usage of prepared linen, dressing material from the cloth in different sizes, and reusable sterilized medical equipment. These items can also be standardized by hospital management using the Sterile Supply module.
