Definitions

  • the present invention relates to the identification, storage and dispensing of blood and blood products to patients requiring blood transfusions.
  • a computer system for controlling the dispensing of blood to a patient comprising: first data entry means for entering first patient record details including blood group and antibody screening details for said patient; second data entry means for entering second patient record details for said patient; said computer system cross-checking said second patient record details against portions of said first patient record details; said computer system determining a set of compatible blood packs for said patient from available blood stocks; third data entry means for entering details of a proposed compatible blood pack from said available blood stocks; and authorisation output means outputting an authorisation when said proposed compatible blood pack is one of said set of compatible blood packs as determined by said computer system.
  • the blood group and antibody screening details can be obtained from testing a sample of the patient's blood and entering them in the first data entry means.
  • the authorisation can comprise printing out adhesive labels for the blood pack and, in an extra step the full details of the blood pack may be re-entered into - - the computer system at a later stage, for example, before dispensing.
  • system can be comprised from multiple computers interconnected in a predetermined manner by means of a network or the like.
  • Both the test results of the patient and the blood products themselves can be time stamped and the computer system can take this into account in refusing to issue any authorisations when certain predetermined time periods have expired. Further, a patient's history can be "built up" and each time transfusion is to occur, this history can be examined to check for any anomalies.
  • the system of the preferred embodiment has the significant advantage that blood release is completely controlled by a computer system. Hence, the preferred embodiment does not need to rely on intervention by laboratory staff during the blood release to ensure pre- transfusion requirements are met.
  • the computer system performs all the checking functions and subsequently matches and selects the compatible pack(s) of blood from an inventory. This allows the preferred embodiment to operate away from the laboratory environment and to be used by non-laboratory hospital staff at remote hospitals interconnected into the computer system of the preferred embodiment.
  • Fig. 1 illustrates the process of a first embodiment in testing a blood transfusion sample
  • Figs 2 illustrates a flow-chart for determining whether transfusion blood should be released by the first embodiment.
  • Fig. 3 illustrates the interaction of computer systems when utilised by a user to dispense blood;
  • Fig. 4 illustrates a flow chart for establishing a EBRS record
  • Fig. 5 illustrates a flow chart for the release of blood in accordance with the second embodiment.
  • the preferred embodiment is to run in an environment in which donated blood for transfusion has been analysed and categorised by blood group and antibody screening with the details being stored on a blood bank computer system and the details of which can be accessed by the preferred embodiment. Further, blood stocks have been delivered to hospital in accordance with expected needs and the level of stocks has been recorded.
  • the method of the preferred embodiment can be divided into two main parts, the first part comprises the testing of a patient's blood to determine its blood group and antibody screening properties. The second part comprises determining blood which should be released to the patient when transfusion blood is needed.
  • Fig. 1 there is illustrated the steps involved in the transfusion testing part of the preferred embodiment.
  • a blood sample taken from a patient, is received along with the patient details.
  • the patient details include the patient's name, birth date, hospital from which the blood is received, and a unique medical record number (MRN) for the patient to which uniquely identifies the patient.
  • MRN unique medical record number
  • the sample is tested 3 at the receiving pathology laboratory to determine the sample's blood group (G) in addition to performing an antibody screening of the blood (S) .
  • the results of the testing process are first entered 4 into the computer system of the main pathology laboratory. These results are entered without any checks being performed against previous results. Details entered include a lab identification number, a patent's medical record number (MRN), the hospital, name, patient birth date and the blood group and antibody screening results. Secondly, the details are entered in a separate register 6 which is separate from the storage of details 4. In the register 6, the sample's lab number and the patient's name are utilised to identify the sample.
  • MRN patent's medical record number
  • step 4 After entry, this information is compared against the information stored in step 4. A further register is maintained of all patient's antibody details. Each time a patient's sample is entered, the antibody register is firstly checked to see if a discrepancy exists and secondly the patient's antibody details are updated. If a discrepancy exists, the process terminates with a relevant notification to the user.
  • the patient's blood group results are again entered at step 6.
  • the entry must be a valid blood group code and the entered blood group code is then validated against all samples previously received for the same patient which had been previously stored in the main laboratory computer system 4 or have been stored in the patient antibody register. Again, any inconsistencies result in termination of the method 1 with an appropriate notice.
  • the antibody screening results S are then entered 6 and checked against all previous records 4 for the same patient in addition to the patient antibody register. Any results that indicate an antibody has been detected, again results in program termination with an appropriate message.
  • EBRS Electronic Blood Release System
  • Figs. 2 and 3 there will now be explained the preferred method of releasing blood at a remote station, such as a hospital or the like.
  • the hospital's computer system is connected to the main laboratory computer system and able to exchange information therewith.
  • Fig. 3 there is illustrated one possible arrangement of computers of the preferred embodiment.
  • a user's computer 30, within a hospital environment is interconnected to the aforementioned main laboratory computer system 31, the hospital's computer system 32 and the blood bank's computer system 33 which contains records of blood donors and blood types.
  • access to the transfusion blood release system begins by utilising a password 21 to access the system running on computer system 30 (Fig. 3) .
  • a high level of security is provided by allowing for multiple passwords before access is achieved.
  • the computer informs the user to enter the required patient's full name, hospital identifier and the date of birth. This data entry is validated by checking for the corresponding EBRS record (7 of fig. 1) located on the main laboratory computer system 31 (Fig. 3), as well as checking the stored details of the results sample 4 and cross-checking against the information which may be available on the hospital's master patient index located on the hospital computer system 33 (Fig. 3) .
  • the blood bank computer system records 33 are searched to - - ensure that no antibodies exist for the person needing the transfusion. If there are any abnormalities or errors, the transfusion blood release system 20 is designed to terminate after reporting any error. As noted previously, the EBRS record is examined to determine if the record is still valid. If a valid record is found, a list of compatible blood pack numbers are determined 24 from those blood packs which are available at the remote site. It is assumed that the blood packs have been pretested and categorised as is the normal procedure for handling donated blood. The user is instructed to choose one of the compatible blood packs. Importantly, the system only displays blood packs that are in date, and have a blood group as previously verified by the dispensing blood laboratory.
  • the user is instructed to enter a donation number previously printed on the selected blood pack in addition to the blood group barcodes on the selected pack.
  • the information can be entered by means of bar codes or the like. This information is then checked to determine if it is correct and a matching label is printed.
  • ABO and Rh(D) typing 40 of patients is performed using anti-A, anti-B and anti-D reagents.
  • Serum typing is performed with Al and B cells against a 2 drop serum tube test.
  • the antibody screening test is performed by a standard tube technique consisting of a ten minute, direct agglutination test at 37°C and a Low ionic strength solution indirect antiglobulm test (LISS-IAT) against a three cell sample screening panel.
  • a second technologist independently 41 determines the patients blood type and enters the patient information and blood type result into the computer.
  • the program validates the current and any historical data. Any discrepancies are flagged for resolution.
  • the program creates a valid EBRS patient record 42 if i) a second blood type has been performed ii) current and historical 44 patient identification and blood type results match 46 and iii) there is no current or historical record of unexpected red cell antibodies 45.
  • a full IAT crossmatch is performed for patients with red cell antibodies and an ISX is performed when no second technologist is immediately available to perform a check of the ABO and Rh(D) type.
  • the EBRS patient record expires after 72 hours if the patient has been transfused within 3 months or is pregnant, otherwise a 14 day expiry applies.
  • Fig. 5 there is illustrated 50 the process of releasing blood in accordance with the second embodiment.
  • Access to the EBRS programs requires dual passwords 51.
  • the computer informs the user to enter 52 the patient's full name, unique hospital number and date of birth. This entry is validated by the laboratory information system, the EBRS database and the Hospital patient information database.
  • the programs searches 53 for a valid blood type and the results of the antibody screen. If the antibody screen is negative a list of compatible RBC unit numbers available at the remote site is displayed 54.
  • the user is instructed to scan the donor unit identifying number and blood type barcodes of the selected unit and if valid, a label is printed. After fixing the label to the unit, the user is instructed to confirm 55 the unit selection by again scanning the unit details.
  • a second label is printed for completion by the medical staff at the time of transfusion for inclusion m the patient's medical record.
  • Immediate electronic mail messages are sent to the central laboratory indicating the release details and to warn the central laboratory when stocks are falling below minimum levels.
