Learning Objectives At the end of this module, you will be able to: • List all supplies required for the optimal performance of Xpert MTB/RIF • Describe ordering processes • Explain the use and importance of the stock log book in maintaining an adequate inventory • Calculate supplies needed based on the number of tests performed during a specific period • Explain storage and shelf life requirements of Xpert MTB/RIF kits and other supplies
Contents of this module • Supply list for Xpert MTB/RIF • Record keeping: Stock log book use and importance • Calculation of supplies to order • Ordering and receipt of supplies • Storage and shelf life of supplies
Supply management means… Properly maintained and adequate supplies to ensure uninterrupted service and to minimize waste
Structure of a supply management system: National level • Countries should consider implementing the centralized (national, regional) management of Xpert MTB/RIF supplies integrated into the general purchase system, as for microscopy or for drugs supplies • The system should be coordinated by the government and should include Ministry of Health, donors and partners
Supply management system Adapt to country-specific system • Describesupply management system(s) in your country
Ordering of Supplies • What to order? • From where? • How much? • How often? • How to assess the correctness of an order? • What is the lead time needed? • What is the reserve (buffer) stock needed? • Who is responsible for placing orders? • Always consider • the shelf-life of the ordered material, and your storage capacity under appropriate conditions
Supplies required for Xpert MTB/RIF:Provided by Cepheid • GeneXpert instrument with computer (laptop or desktop) and barcode reader • When ordering, specify the working language to ensure a proper keyboard, etc. • Kits of Xpert MTB/RIF test cartridges • Kits of Xpert MTB/RIF calibrationcartridges Note: Cepheid can provide a UPS (uninterruptable power supply)*, which provides very limited power backup. However it is better to procure a UPS (and batteries, etc) locally *Specifications: Online UPS - Powervar. 800 VA capacity for a 4-module GeneXpert and computer; 110v or 220v depending on country. Minimal transfer time 4ms max. Extra batteries can be added to extend duration.

Stock management It is Good Laboratory Practice to have a designated person for supply management, who performs the following activities: • Performing a “stock count” • Maintaining proper inventory records • Determining how much to order to avoid stock-outs and expiring of cartridges • Placing orders properly • Inspecting and verifying supplies received • Ensuring proper storage of stock
Stock log book: required data • Date and amountordered • Date of receipt of item • Amount received • Lot-number • Expiry date • Amount of used items • Balance of items still in stock
Stock Log Book: Example To be customized by each country Item name: ________________ Unit: ______________________
Perform a stock count • What is it? Physically counting each item in the stock • When is it done? Recommended at the end of each month • Who does it? A designated person All items must be accounted for. Everything that comes in and goes out must be recorded
Data required for calculating supplies • Number of tests performed (average per month) • Stock on hand (physical count) • Shelflife • Lead time • Period of time to cover with the supplies The followingexamples are for a facility-basedsupply management and canbecustomizedforuse at the central level
Examples of items required • Items • Sputum containers • Xpert MTB/RIF kits • Concentrated bleach solution • Disposable Pasteur pipettes
Calculate quarterly requirementforXpertMTB/RIF tests Adapt to country-specific system * * Or other time period
Quantities required for one Xpert MTB/RIF test (B) To be customized by each country
Total number of tests performed in the previous quarter The value (A) equals the number of Xpert MTB/RIF tests performed during the previous quarter
Calculation for one quarter of supply of an item (C) • The value (C) equals the quantity of an item required for one quarter • Calculate (C) by multiplying the number of tests performed during a quarter (A) by the amount of the item needed for one examination (B), therefore: A x B = C
Example 1: to calculate one quarter of supplyof Xpert MTB/RIF cartridges (C) • In the last quarter, you performed 600 Xpert MTB/RIF tests (A) • You need 0.02 of Xpert MTB/RIF kits (50 tests in kit) per test (B), so how many kits will you need for the next quarter (C)? • A x B = C • 600 tests x 0.02 kit/test = 12 kits
Example 1: to calculate reserve quantity (D) of Xpert MTB/RIF kits • The value (D) equals a one month consumption quantity of an item that must be kept as a reserve • The value (D) is equal to (C)/3, the quantity of an item calculated for one month: D= C/3 • Reserve stock of Xpert MTB/RIF kits equals 12 kits (C) /3= 4 kits (D)
Example 1: to calculate Xpert MTB/RIF supply, stock on hand (E) • The value (E) equals the stock on hand • Determine (E) by the an actual physical count of existing stock (inventory) • Assume stock in hand is 3 Xpert MTB/RIF kits
Example 1: to calculate required quantity (F) of Xpert MTB/RIF kits • The value (F) equals the quantity required for one quarter (C) plus the quantity required for one month reserve (D) less the stock on hand (E) • Calculate (F) as follows: (F)= C+D-E • Stock is hand is 3 Xpert MTB/RIF kits • Calculatedquantity of kits to order foronequarter is: 12 (C) + 4 (D) – 3 (E) = 13 (F)
Example 1: to calculate requested / issued quantities of Xpert MTB/RIF kits • Round up the calculated quantity to a quantity consistent with the unit of issue • The calculated quantity of kits is 13 • The order unit is box (50 tests) • Order 13 boxes (650 tests)
Example 2: to calculate one quarter of supplyof bleach solution (C) • In the last quarter, you performed 600 Xpert MTB/RIF tests (A) • You need 1.5 ml of concentrated bleach solution per test (B), so how much concentrated bleach solution will you need for the next quarter (C)? • A x B = C • 600 tests x 1.5 ml/test = 900 ml
Example 2: to calculate reserve quantity (D) of bleach solution Adapt to local setting and supplies’ shelf life • The value (D) equals a one month consumption quantity of an item that must be kept as a reserve • The value (D) is equal to (C)/3, the quantity of an item calculated for one month: D= C/3 • Reserve stock of concentratedbleachequals 900 ml (C) /3=300 ml (D)
Example 2: to calculate supply of bleach, stock on hand (E) • The value (E) equals the stock on hand • Determine (E) by the an actual physical count of existing stock (inventory) • Assume stock in hand is 400 ml of concentratedbleach
Example 2: to calculate quantity (F) of bleach solution to order • The value (F) equals the quantity required for one quarter (C) plus the quantity required for one month reserve (D) less the stock on hand (E) • Calculate (F) as follows: (F)= C+D-E • Stock in hand is 400 ml • Calculatedquantity of bleach to order foronequarter is: 900 ml (C) + 300 ml (D) – 400 ml (E) = 800 ml (F)
Example 2: to calculate quantities of bleach solution to request/issue • Round up the calculated quantity to a quantity consistent with the unit of issue • The calculated quantity of bleach solution is 1824 mL, round it up to 2 liters • The order unit is 1 liter bottle • Order 2 bottles
