Need for materials management - 1
• Financial benefit
– Materials make upto 40% of total expense in
health centres
– Effective management can release funds for other
purposes
• Better availability of materials
– Adequate supply of right material at the right place
whenever required
– Avoid out-of-stock situations

7. 7Rizwan S A CCM, AIIMS
Need for materials management - 2
• Complexity in health sector
– Technical, non-technical, consumable and non-consumable
items peculiar to health sector
• Cold chain
– Vaccines to be maintained in cold chain from the point of
manufacture to point of use
• Contraceptive supply
– High priority, must be available at all times throughout the
country
• Scope for improvement
– Cost-effectiveness mostly ignored in public sector

11. 11Rizwan S A CCM, AIIMS
Identification of items
• Large number of aggressively marketed drugs
under proprietary names
• A hospital committee – to decide the list of
drugs to be purchased (based on prevalent
morbidities and funds)
• Prefer cheap & safe generic drugs to costly
proprietary drugs

13. 13Rizwan S A CCM, AIIMS
Estimating demand - 1
• From previous trends – monthly, quarterly or
annual requirements can be estimated
• Unusual occurrences (epidemics) sh. be taken
into account
• Eg. Estimating vaccine requirement in PHC

14. 14Rizwan S A CCM, AIIMS
Estimating demand - 2
• Estimating vaccine requirement
– No. of beneficiaries, No. of doses of each vaccine,
Wastage factor, No. of sessions
– E.g. Requirement of TT for pregnant women
• A HSC with 5000 population and birth rate of 30/1000
• 150 births with 10% pregnancy wastage = 165
• Total TT doses 165 X 2 = 330 doses
– E.g. For children
• Birth rate, IMR, no. of infants alive at one yr. of age
• Wastage factor for DPT, OPV = 1.33, BCG, Measles = 1.33
for 5 dose vial, 2 for 10 dose vial
• No. of doses divided by no. of doses per vial will give the no.
of ampoules/vials required

15. 15Rizwan S A CCM, AIIMS
Estimating demand - 3
• Estimating IFA requirement
– No. of pregnant mothers = 165
– No. of tablets required = 16500
– 50% of women will be anaemic and require extra
100 tablets
– So total required will be = 16500 + 8250
• Similarly requirement for IFA (paed), ORS,
Septran can be calculated

17. 17Rizwan S A CCM, AIIMS
Purchase and procurement
• Objective – maximum value for rupee spent and have
minimum of delay
• Centralised
 Ordering in bulk makes negotiating easy and reduces cost,
eliminate middleman, quality control
 Disadvantages – delay in supply, consumer dissatisfaction
• Decentralised
 Peripheral units buy their own supplies, avoids delay,
consumer satisfied, flexibility,
 Disadvantages – office work increases, lack of interest or
expertise

18. 18Rizwan S A CCM, AIIMS
Procurement in PHC
• Indenting from District level/CMO
• Action plan form (form 2)
• Supplies are received quarterly, but earlier
replenishment can be requested

Issue procedure - 1
• A procedure that saves time, reduces paperwork and
prevents duplication
• Written indent for issues to various depts., special rules for
dangerous and costly drugs
• First In First Out principle
– Keeping older stock in the front and newer stock at the back
• Push or allocation system
– Decision making at the top level
• Pull or requisition system
– Peripheral outlets draws stock from central stores
• Mixed system

27. 27Rizwan S A CCM, AIIMS
Issue procedure - 2
• Maintain Stock Register
• The pharmacist or the user sh. be asked to maintain a
separate register for entering daily usage of each item
• At the end of each month the balance sh. be checked
physically

and stock in hand – maintained for each item
separately
• Stock verification regularly to ascertain
physical quantity

33. 33Rizwan S A CCM, AIIMS
Inventory management - 1
• It is method of maintaining stock of items
– At a level at which purchasing and stocking costs are the
lowest possible
– Without interference with supply
• There should be a balance in stocking
– If large quantities of drugs are purchased there will be no problem of
supply and out-of-stock situation
– But maintaining large amount of items is like storing money which
could have been used for other useful purpose
– A large stock will require space and staff to manage it
– Pilferage, loss, expiry, better and newer cheaper alternatives
– The yearly carrying cost of inventory is about 25%

34. 34Rizwan S A CCM, AIIMS
Inventory management - 2
• Managing inventory in a systematic way avoiding over or
under stocking is a scientific process
• General principal
– Fast moving items which have large consumption must be
ordered frequently while maintaining a safety buffer stock
– Items which have small consumption must be ordered
frequently with a large buffer stock
• Some techniques
– ABC analysis
– VED analysis
– SDE analysis
– FSN analysis

35. 35Rizwan S A CCM, AIIMS
ABC Analysis - 1
• Divides inventory into three classes based
on annual cost
 Class A - high annual cost
 Class B - medium annual cost
 Class C - low annual cost
• Category A drugs should get high priority
because they account for bulk of
expenditure, their consumption, purchase
must be critically watched

39. 39Rizwan S A CCM, AIIMS
VED analysis
• Vital (10%) - life saving drugs, no alternatives,
can’t afford to have out-of-stock
• Essential (40%) - absence can be tolerated for
short stretches and alternatives are available
• Desirable (50%) – absence can be tolerated for
longer periods

Combined ABC and VED
V E D
A AV AE AD Category I – 15%
B BV BE BD Category II – 40%
C CV CE CD Category III – 45%
• Cat I – continuously monitored, keep minimum safety stock to
reduce carrying cost
• Cat II – mid level managers, low priority, moderate control
• Cat III – low level managers, high buffer stocks, lower priority

41. 41Rizwan S A CCM, AIIMS
SDE analysis
• Scarce – imported, frequently in short supply
• Difficult – difficult to obtain in quantity or quality
• Easy – easily available
FSN analysis
• Fast moving – large consumption
• Slow moving – small consumption
• Non-moving – obsolete drugs, lockup space and funds and
usually condemned due to expiry

42. 42Rizwan S A CCM, AIIMS
Methods of ordering
• Two bin system
• Cyclic system
• Economic order level

43. 43Rizwan S A CCM, AIIMS
Two bin system
• New order is placed when stocks reach a predetermined
level for which following information is required
Lead time – the interval between placing order and receiving
supply, may vary from item to item
Buffer stock – stock maintained as insurance against variations
in consumption
 In RCH, for very crucial items recommended buffer is 10% and 5% for
rest of the items
Reorder level – the level at which new order is placed, equals the
amount that will be consumed in the lead time plus buffer stock

44. 44Rizwan S A CCM, AIIMS
Cyclic system
• Various items are checked with certain
periodicity called review period
– Find out consumption, balance in hand
– The period between orders is fixed
• The quantity ordered depends upon lead time
– It the lead time is less than the review period, the
amount ordered will be the difference between
maximum stock and stock in hand

Economic order quantity
• It is the order quantity that minimizes total
inventory holding costs and ordering costs
• EOQ is fixed for each item taking into account
– Annual requirement
– Cost of carrying inventory
– Cost ordering
• We want to determine
– the optimal number of units to order
– so that we minimize the total cost associated with the
purchase, delivery and storage of the product

52. 52Rizwan S A CCM, AIIMS
Economic order quantity
• Variables needed to calculate EOQ = optimal
order quantity
 Q = order quantity
 D = annual demand quantity
 S = fixed cost per order (typically cost of ordering and shipping and
handling. This is not the cost of goods)
 H = annual holding cost per unit (carrying cost) (warehouse space,
refrigeration, insurance, etc. usually not related to the unit cost)

EOQ Model - advantages
• The EOQ model is robust
• It works even if all parameters and
assumptions are not met

Outline
• Introduction
• Need for materials management
• Components of materials management
• Details of Inventory management
• Managing equipment
• Managing drugs

57. 56Rizwan S A CCM, AIIMS
Managing equipment
• Four main procedures
Ordering -(obtaining from stores)
Storing -(recording, labelling, holding)
Issuing -(giving out, recording the issue and
balancing the stock, signed voucher)
Controlling/maintaining

58. 57Rizwan S A CCM, AIIMS
Ordering equipment
• Making list
– A list of all required items, the exact quantity
• Balancing needs and resources
– Making a cost estimate
• Using a catalogue
• Completing order/requisition form

59. 58Rizwan S A CCM, AIIMS
Storing equipment
• Equipment is stored in 2 places
– A main store where stocks are kept
– The place of use
• Receiving new items
– Noting in the stock register, the date, reference
number, invoice number, and quantity of items
• Keeping ledger balance after issue

60. 59Rizwan S A CCM, AIIMS
Issuing equipment
• Ledger record
– The issue of items is noted and the balance is
entered
– Issue voucher is an official form with date,
quantity, department of use, recipient, and sign

61. 60Rizwan S A CCM, AIIMS
Controlling/maintaining
• Convincing staff that equipment must be
cleaned, inspected and kept in good order,
defects must be reported immeddiately
• Inspection checklist and inspection schedule
• Detecting discrepancies and taking action
• Keeping accurate equipment records

63. 62Rizwan S A CCM, AIIMS
Managing drugs - 1
• The objective of managing drugs is to use
drugs wisely and avoid wasting them
• Educate staff about use of drugs
– Notes on common drugs
– Correct doses
– Discuss wastage in staff meetings
– Lecture/discussion on common drugs
• Educate patients

64. 63Rizwan S A CCM, AIIMS
Managing drugs - 2
• Preparing a standard drug list
– Selected from a list of essential drugs
– Depending upon common diseases in the hospital
– New drugs availability
– Budget
• Estimating requirement; ordering and stocking

65. 64Rizwan S A CCM, AIIMS
Managing drugs - 3
• Stock-card system
– Sometimes used instead of a ledger

66. 65Rizwan S A CCM, AIIMS
Managing drugs - 4
• Issuing and controlling use of drugs
• It helps in identifying when stocks need reordering,
checking usage against treatment, detecting discrepancies,
check usage in different depts.
• A/B or Double-shelf system
– when shelf A is used up
order is placed for new stock
– Part B will be used up by the
time the new order arrives

67. 66Rizwan S A CCM, AIIMS
Managing drugs - 5
• Controlling life saving drugs
– Make a list of such drugs
– Place them together in one shelf
– Check frequently, Order new supply when
depleted to half
• Prepacking drugs
for outpatient

68. 67Rizwan S A CCM, AIIMS
Eg. TNMSC Model
• TNMSC, the state government's drug
procurement agency, is considered
among the best centralized and
efficient public sector drug
procurement mechanism in the
country
• Primary objective - ensure ready
availability of all essential drugs and
medicines
• These improvements have helped
bring down the average cost of drugs
for inpatients in Tamil Nadu’s public
hospitals to Rs. 102, (3,268 Haryana,
2,166 Himachal Pradesh, 3,187
Rajasthan)
