METHODS AND SYSTEMS FOR MONITORING THE ADMINISTRATION OF DRUGS TO FARM ANIMALS
Field of the Invention
This invention relates to methods and systems for monitoring the administration of drugs to farm animals.
With the increasing demand for tighter controls on the health of farm animals, there is a perceived requirement for improved methods and systems for monitoring the administration of drugs to farm animals. It is an object of the present invention to meet this requirement.
Summary of the Invention
According to the present invention there is provided a method of monitoring the administration of drugs to farm animals, which method indudes:- a) storing the drugs in a dispensary in bar-coded containers,
2 b) providing each user or dispenser of the drugs with a portable data terminal, the user typically being a veterinary surgeon or an employee of a veterinary practice, c) recording the drugs taken from the dispensary by each user by scanning the bar codes of the drug containers, d) at the point of supply, entering information into the portable data terminal concerning the customer to whom the drug or drugs is or are being supplied, the respective dose and the i.d. number of the animal, if appropriate, e) scanning the bar code of the or each container of the drug or drugs being supplied, and f) printing a label concerning the or each drug for inclusion in the customer's records.
Two labels are preferably printed for each drug, one for inclusion in the customer's records and the other for attaching to the container for that drug. Each label typically includes information concerning the veterinary practice, the customer, for example, a farm or farmer, the name of the drug, the dose and the batch number of the drug. Each label may also include the animal i.d. number, if appropriate, plus the meat/milk withdrawal times for that particular drug.
The point of supply may be a farm attended by the veterinary surgeon or it may be the practice dispensary.
Means are preferably provided whereby the information held in the portable data terminal is downloaded into a memory or the
like. A software package may thus be provided which enables the veterinary practice to monitor where each drug has been issued and the dosage supplied. It will also enable the practice to monitor the drugs supplied by each veterinary surgeon or employee. The software package may also include an accountancy package whereby invoices for the customers are produced based on the information downloaded from the portable data terminals.
The drugs supplied to the dispensary may already have a bar- coded label. If not, each drug or other consumable product entered into the stock of the dispensary will be allocated a PDF (Portable Data File) bar-code label which is attached to the pack or container. The PDF codes are owned and originated by Symbol Technologies. The bar code is preferably a two-dimensional bar code and will contain information concerning the product name, the batch number and the expiry date. One-dimensional bar codes can also be scanned.
Each veterinary surgeon will normally have a stock of drugs in the boot of his car and the method of the information will enable the veterinary practice to check that each of the members of the practice is accurately recording all sales (supplies) of drugs, i.e. total quantity of drugs taken from dispensary = drugs issued to customers + drugs in boot of car.
The method preferably includes scanning all the drug containers in the dispensary at regular intervals so as to obtain an
4 indication of the stock level at the time of scanning, and ordering additional drugs to bring the level of stock to a predetermined level.
One of the portable data terminals will thus be used by a person, or one of the people, responsible for day-to-day operation of the dispensary to scan all the drug containers then in stock. The information thus obtained will then be compared with information concerning the desired operational stock level and instructions will then be transmitted, via a modem, to a drugs wholesaler to order the quantity of drugs necessary to bring the stock level back to the desired operational level.
The memory of this portable data terminal will accordingly be up-graded at regular intervals with information concerning any new drugs and concerning any required changes to the desired operational stock level.
According to a second aspect of the present invention there is provided a system for monitoring the administration of drugs to farm animals, which system in udes:- a) means for storing the drugs in a dispensary in bar-coded containers, b) a portable data terminal for each user of the drugs so that each user can record the drugs which he or she takes from the dispensary by scanning the bar codes of the drug containers, and c) means whereby, when information has been entered into the portable data terminal concerning the customer to
5 whom the drug or drugs is or are being supplied and the respective dose, and the bar code of the or each container of the drug or drugs being supplied has been scanned, a label is printed concerning the or each drug for inclusion in the customer's records.
As mentioned above, means are preferably provided whereby the information held in a portable data terminal is downloaded when, for example, a veterinary surgeon returns to the practice after having visited a number of farmers. The practice records can thus be maintained accurately and efficiently without having to depend on the memories of each of the members of the practice and the ability of any particular member to decipher the hand-written scribbled notes or messages of other members of the practice.
One of the portable data terminals is preferably provided with information concerning the desired operational stock level for the dispensary and is used, at regular intervals, to scan all the drug containers in the dispensary so as to obtain an indication of the stock level at the time of scanning and to order additional drugs to bring the level of stock back to said desired level.
There may thus be a direct link between a modem in the dispensary and a modem at the premises of a wholesaler of the drugs.
The software for said portable data terminal will preferably be up-graded at regular intervals to include additional data concerning
6 any new drugs as well as being up-dated with information concerning price changes and any changes in marking or other requirements for the drugs being dispensed.

Description of the Preferred Embodiments
Stage 1. As each container 10 containing a drug or other consumable item is entered into the stock in the dispensary 11 , it is allocated a PDF (Portable Data File) two-dimensional bar-code label. A bar-code label is attached to each container 10 and is produced by means of a bar-code labelling device, which may be combined with a Portable Data Terminal 12. The bar code contains information in respect of the Product name, Batch Number and Product Expiry Date.
Stage 2. As each drug is taken from the dispensary, by either a veterinary surgeon 13 or a member of the lay staff of the veterinary practice, it is recorded on a Portable Data Terminal 12, for example, a PDT3500 produced by Symbol Technologies, as having been issued to that particular person. Each veterinary
surgeon 13 will thus maintain a stock of drugs in his vehicle 14 and will replenish it as necessary.
Stage 3. As a veterinary surgeon 13 uses or dispenses each drug on a farm, he or she scans the PDF bar-code label on the container 10 for that drug and, via the keyboard of the Portable Data Terminal 12, enters the name of the farm and the dose of the drug to be used.
Stage 4. The veterinary surgeon then produces two fully typed labels 15 using a portable label printer, e.g. a "DATAMAX" printer. Each label 15 will have on it the veterinary practice details, the farm details, the name of the drug, the dose, the Batch Number, the animal i.d. number, if appropriate, and the meat/milk withdrawal times. Each label 15 will conform to all current regulations and all anticipated future requirements. One label 15 is attached to the dispensed drug container 10, while the other is given to the farmer to place in his drug record book.
Stage 5. On return to the veterinary practice, the information held in the Portable Data Terminal 12 is downloaded into a software package enabling the veterinary practice to monitor: - a) where each drug has been issued, b) in what quantity, and c) by which veterinary surgeon, thereby providing a fully traceable drug tracking system.

Drugs issued by the lay staff are scanned and issued in the same way as on a farm but are dispensed to farmers directly from the dispensary utilising the Portable Data Terminal 12 kept in the dispensary.
The Portable Data Terminal 12 kept in the dispensary is also used to scan all the drug containers 10 in the dispensary at regular intervals so as to obtain an indication of the current level of stock in the dispensary. The information obtained by scanning the containers 10 is then compared with information concerning the desired operational stock level and instructions transmitted, via a modem (not shown), to a drugs wholesaler to order that quantity of drugs necessary to bring the stock level in the dispensary back to the desired operational level.
The memory of the Portable Data Terminal 12 in the dispensary is up-graded at regular intervals, by means of software supplied by the system operator, so as to provide it with information conceming:- a) any new drugs, b) any price changes, c) any changes in regulations or marking procedures, and d) any other requirements.
The system shown in Figure 2 operates in the same way as the system shown in Figure 1 though, for convenience, Stage 4 has not been shown. The Figure 2 system includes the additional step that, at Stage 5, when the information is downloaded from the
9
Portable Data Terminal 12, the information is additionally entered into an accounting package. The downloaded information is fully editable before being posted to a Sales Ledger and is used to create an invoice 16
The systems shown in Figures 1 and 2 can each be interconnected with a logging system The data downloaded into the computer will then be reproduced in the form of a spreadsheet the use of which will allow the practice manager to identify which individual veterinary surgeons and/or lay staff are not fully recording all sales of drugs at the farm or counter level, for example, for an individual veterinary surgeon, drugs taken from the dispensary = drugs issued to farms + drugs in boot of car.
The present invention thus permits a veterinary practice to operate more efficiently and effectively while, at the same time, accurate data is maintained as to where drugs are issued , by whom and for which animals they have been prescribed.
