Horsley has defined true inventory as
the sum total and cost of all supplies official and unofficial wherever they may be stored, that have not yet been used.
Hospital inventory consists of the material that a hospital carries into storage area. This represents a sizeable portion of a hospital asset.

TYPES OF INVENTORYTYPES OF INVENTORY
OFFICIAL INVENTORY - is that which is brought into a storage space or unit, counted and controlled unit list is dispensed to a using department. Example:
medical and surgical store inventory
pharmaceuticals items dietary items like cereals, pulse etc engineering item
![Page 8: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/8.jpg)
linen item any other items
UNOFFICIAL INVENTORY - it is those supplies that have been expensed and dispensed from the central stores to the various departments and unit where they are stored until stored such as wards, OT, ICU, dialysis, OPD etc.

INVENTORY CONTROLINVENTORY CONTROL
INVENTORY CONTROL - is basically a managerial function to keep the inventory at minimum Quality so that at a particular point of time there is minimum dead stock and minimum money in blocked. This minimum quantity should be sufficient to run the supply.
![Page 10: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/10.jpg)
According to Stafford, the inventory control system in
hospital is “ valuable management tools for monitoring large supplies of materials, for ensuring a smooth out” orderly flow of materials and containing costs and generating greater efficiently.
![Page 11: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/11.jpg)
According to Timmappaya, the inventory control is basically
a scientific system which indicates as to what to order, how much to order and how much to stock so that the purchasing and storage cost are kept as low as possible. It is a tool of management used to maintain an economic minimum investment in materials for obtaining financial return.

INVENTORY CONTROLINVENTORY CONTROL
Inventory control is the function , which attempts to maintain stock at their level.
it has four main PURPOSES To ensure that stock does not rise so
high that all the company’s capital is out of circulation.
To maintain the balance of the stock. To maintain the accuracy of the
accounts. To guard against theft, depreciation
and obsolescence.
![Page 13: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/13.jpg)
The function , which measures the stock at regular interval, compares it with planned levels and feed backs warning of variances.
The AIM of inventory control are:
To conserve the capital To maintain balance To maintain the accuracy of the
accounts

With stock control by steps of order release inventory control and production control are fully integrated
With all other system, they are closely related but separate.
In inventory control, we are mainly concerned with the quantity and value of stock, checking the balance, loss, depreciation and obsolescence and reconciliation between the actual accounting stock.
![Page 15: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/15.jpg)

AIMAIM
To study the inventory management techniques followed in general stores of a tertiary care teaching hospital.
![Page 19: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/19.jpg)
METHODOLOGYMETHODOLOGYThe study was carried out in the
general stores at a tertiary care teaching hospital in two phases as follows:
Phase 1 A prospective study was conducted
between 1st APRIL 2006 TO 31st 2007. Selective inventory control-ABC inventory classification was applied and analyzed.
![Page 20: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/20.jpg)
Phase IIPhase II
A prospective study was
conducted for a period of one month from 1st August 2007 to 31st August 2007 to do an ‘overall analysis’ of the inventory. The analysis was done in two parts:
![Page 21: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/21.jpg)
Analysis 1Analysis 1
1. The trend in the inventory was studied by perusing the records for last five years. The average annual inventory was calculated as follows:
(a) The opening and closing stock was considered for each month of a year.
(b) Average inventory for a month was calculated as follows:
![Page 22: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/22.jpg)
CONT..CONT..Average inventory =Opening Stock +
Closing stock (c) The average inventory for a year was
calculated by taking the mean of monthly inventories.
(d) This was extended for last five years.

CONT..CONT..2. The trend in annual inventory turnover was
studied by perusing the records for last five years.
The annual inventory turnover was studied by perusing the records for last five years. The annual inventory turnover was calculated as follow:
(a) The total sales/issues from the stores in each year were considered.
(b) This was divided by the average inventory for that year.
(c) This was extended for last five years.

Analysis 2Analysis 2The concept ‘vendor-based’ inventory as
applicable to the stores was analyzed as follows:
(1) A detailed discussion was done with the finance Manager of the hospital.
(2) The fraction of inventory , on the last day of each month , and inventory within 30 days of the procurement date, was calculated. this fraction represented the ‘vendor based’ inventory. Relevant software, available in the general stores, was used for this calculation.
![Page 25: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/25.jpg)
CONT..CONT.. (3) Data, for final calculation, was taken from
successive months to nullify the skewing effect.
(4) The last 16 successive months were taken,
for the final calculation, starting from august 2007.
(5) The calculation of sample size of 16 was done at a significance level of 5% and with a permissible error of 3% ‘Epi-info’ software was used.

ABC ANALYSISABC ANALYSIS
This is known as Always Better Control.
This is also known as pareto’s law.(vilfredo pareto)
In this analysis the items are classified in three categories A,B,C.
![Page 27: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/27.jpg)
‘A’ grade items accounting for 70% of total inventory value.
‘B’ grade items accounting for 20% of total inventory value.
‘C’ grade items accounting for 10% of total inventory value.
The capital locked up in the A category items are should be low as possible
![Page 28: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/28.jpg)
Total number of minor items in stores is 2273. ABC category
Item category Annual consumption Numbeof items number of cost(in%), items (in
%)
A 70% 217 9.55% B 20% 513 22.57%
C 10% 1543 67.88%
![Page 29: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/29.jpg)
The A category items are most valuable items and bear the maximum cost.
The B category items are valuable items but they are least valuable item as compare to A.
The C category items are large in quantity but the price of these items are low as compare to A & B.
![Page 30: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/30.jpg)
The methodology for idntifying various category of items is as follows : steps are;
The cost of each items of the inventory is multiplied by the total quantity used during the given time,usually annual usage of the items.
The items are arranged in descending order of the
numerical value.
The cumulative valye of the items written aganinst each in the next column.
The cut off points are drawn at various level

Inventory AnalysisInventory Analysis
Inventory analysis is a systematic analysis of all items in stores for achieving the objectives of effective inventory control
The three levels of analysis are ;overall analysisCategory analysisIndividual item analysis
![Page 33: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/33.jpg)
Overall analysis◦Inventory carrying index◦Compare-Purchase & consumption
with receipt & issue◦Takes a bird’s eye view of total
inventory over a period of time to find out existence Individual item analysis
![Page 34: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/34.jpg)
Category analysis
◦ Second level of analysis wherein stocks of ech category of similar items is analysed
◦ like antibiotics,analgesic,expectorant etc.
◦ In order to achieve optimum stock levels and effective controls, the management should fix levels for each category of items acording to nature of items, lead time etc.
![Page 35: INVENTORY MANAGEMENT IN GENERAL STORES OF A TERTIARY](https://reader036.fdocuments.in/reader036/viewer/2022070306/5517292e497959a3308b4810/html5/thumbnails/35.jpg)
Individual item analysis◦It is desirable to classify/group the
items, and subject each class/group to control, commensurating with its importance. This item may be classified/grouped according to their value, utility, consumption, lead time etc.
