  • Essentials for Inventory Management

    Content

    Inventory Management (IM) is a systematic approach to ordering, receiving, storing, issuing and reordering drugs and other commodities. IM is a critical element in supply chain management which ensures the availability of the right products in the right place at the right time.

    Under the National TB Elimination Programme (NTEP), IM refers to the activities carried out by the officer-in-charge of logistics and includes the following:

    1. Determination of Stock Status at the SDS and DTCs/ Subordinate Stocking Points: The pharmacist will determine the drug stock status of their store and of all the sub-units up to PHIs through Ni-kshay Aushadhi.
    2. Review of Adequacy of Stock: The Pharmacist will analyse the adequacy of stocks on the basis of the available stock and estimated consumption as per the stocking norms.
    3. Correction of Imbalances through Transfers: Based on the review of drug adequacy, the officer-in-charge will flag all the sub-stores that are significantly under or overstocked.
      1. The needs of sub-stores flagged as understocked will be addressed through the Additional Drug Request (ADR) or Drug Transfer Advice (DTA) mechanism.
      2. The stocks at the sub-stores flagged as overstocked or with close to expiry drugs will also be corrected by the DTA mechanism.
      3. These transfers will only be authorised by the State TB Officer (STO)/ District TB Officer (DTO)/ officer-in-charge and should be recorded in Ni-kshay Aushadhi.
    4. Replenishment of Stock: The stocks at the stores are replenished on a quarterly basis, pursuant to the review and validation of the reports available in the Ni-kshay Aushadhi.

  • Stocking Norms

    Content

    The National TB Elimination Programme (NTEP) strives to ensure an uninterrupted supply of drugs, and stocking norms have been developed by the Central TB Division (CTD) to help achieve this goal.

    The drug stocks equivalent to 10 months of consumption, shall be maintained with implementing states.

    The table shows the quantity of reserve stocks at each level at the start of the quarter (considering the receipt from one higher level).

    Table: Stocking norms for First line anti-TB drugs for adults to be followed at each level
    Level Stock for Utilisation (Months) Reserve Buffer Stock (Months) Drug Requirements
    State Drug Store (SDS) 0 3 (Quarterly consumption / 3) X 10 – (existing stock in SDS including stocks at all districts at end of the quarter)
    District Drug Store (DDS) 0 3 (Quarterly consumption / 3) x 7 – (Existing stock in District TB Centre (DTC), TB Unit (TU) and Peripheral Health Institution (PHI) drugstores at end of the quarter)
    TU Drug Store 0 2 (Quarterly consumption / 3) x 4 – (existing stock in TU including PHI drug stores at end of the quarter)
    PHI 1 1 (Monthly consumption x 2) – (existing stock in PHI at end of the month)

     

    Based on the state stock availability and consumption, the stock is supplied from SDS to the district drug store to its TUs and then to the PHIs. This stocking pattern may be denoted as the 3-3-2-2 (SDS-District-TU-PHI) inventory-stocking norm, aggregating 10 months of inventory at the state level.

    • At the start of the quarter, PHIs are supplied with a stock of 2 months (as shown in the table above)
    • Every month, they are supplied with stock from the TU based on consumption, which helps to maintain 1 month reserve stock for utilization at the PHI
    • This reserve stock helps the PHI to provide drugs if more patients are put on treatment in a particular month and to provide cover for delays in supplies from TU
    • Thus, no patient is sent back due to a lack of drugs
    • For the TU level to ensure that the PHIs have 1-month utilization stock plus 1-month reserves, it needs to have a reserve stock of 2 months at the beginning of the quarter
    • In this way, the continuous supply of drugs is maintained

    Paediatric Stocking Norms

    Paediatric drug stocks equivalent to 10 months' consumption will also be kept, but paediatric boxes are not expected to be kept at PHI levels. The stocking of paediatric boxes has been limited to the TU level only.

    The paediatric stocking pattern may be denoted as the 3-3-4 (SDS-District-TU) inventory stocking norm, aggregating 10 months of inventory at the state level.

    SDS 0 Months 3 months (Quarterly consumption/3) X 12 – (existing stock in SDS including stokes at all districts at the end of the quarter)

    TU drug store 0 Months 2 months (Quarterly consumption/3) X 6 – (existing stock in TU including HF drugs stores at the end of the quarter)
