Abstract

Apparatus and methods are described for ensuring that blood transfused into a patient is the correct blood for that patient, is transfused in the correct manner and that a complete audit trail is created that will allow later tracing of blood from donation through to ultimate transfusion.

Claims

1. A method for recording an audit trail for a blood transfusion, said method comprising the steps of:

(a) allocating from a supply of blood, a blood transfusion unit for a patient wherein the blood transfusion unit is marked with an identifying code;

(b) labeling the blood transfusion unit with a compatibility level having patient identification information and said blood transfusion unit identifying code;

(c) generating a blood request form for the patient, the blood request including patient identification information;

(d) placing the blood unit in a secured location for collection by a person authorized to collect said blood transfusion unit;

(e) recording on the blood request form for said patient (i) identification information for said authorized person collecting said blood transfusion unit, (ii) the time of collection, and (iii) the patient identification information;

(f) providing the patient with a wristband having patient identification information;

(g) recording identification information for the person performing a blood transfusion for said patient;

(h) recording the patient identification information on the patient wristband;

(i) recording the patient identification information on the compatibility label;

(j) recording the blood unit identification code on the compatibility label;

(k) recording the blood unit identification code on the blood unit;

(l) comparing the patient identification information on the patient wristband with the patient identification information on the compatibility label, and recording the results of the comparison;

(m) comparing the blood unit identification code on the compatibility label and the blood unit identification code on the blood unit and recording the result of the comparison;

(n) recording the time at which the blood unit is transfused;

(o) comparing the time of transfusion to the time the blood unit was collected from the secured location and calculating the time elapsed between the time of transfusion and the time of collection from said secured location; and

(p) providing a warning if the elapsed time is greater than a pre-set limit.

2. The method of claim 1, further comprising the step of producing a warning if the patient identification information on the wristband does not match the patient identification on the compatibility label.

3. The method of claim 1, further comprising the step of producing a warning if the blood unit identification code on the compatibility label does not match the blood unit identification code on the blood unit.

4. The method of claim 1, further comprising the step of recording vital signs of the patient as the transfusion begins.

5. A method for transfusing blood or a blood product into a patient, said method comprising the steps of:

(a) obtaining patient identification information from said patient;

(b) recording in a database said patient identification information;

(c) collecting a blood sample from said patient;

(d) testing said blood sample to determine the patient'"'"'s blood type;

(e) recording in said database said patient'"'"'s blood type;

(f) allocating for said patient a blood unit comprising said patient'"'"'s blood type, said patient allocated blood unit having a unique identifying code;

(g) recording in said database said patient allocated blood unit'"'"'s identifying code;

(h) making a request for said patient allocated blood unit;

(i) recording in said database said request for said patient allocated blood unit;

(j) transporting said patient allocated blood unit to the location of said patient;

(k) collecting said patient allocated blood unit and recording the time of collection;

(l) transfusing said patient with said patient allocated blood unit and recording the time of transfusion; and

(m) recording in said database information concerning the transfusion of said patient allocated blood unit, said information including a comparison of the time of collection with the time of transfusion.

6. A method for collecting and storing information about blood transfusions in a computer database, said method comprising the steps of:

(a) providing a reader for patient identification information on a patient wristband;

(b) printing a sample identification label for a blood sample collected from said patient, wherein said sample identification label comprises said patient identification information;

(c) transmitting said patient identification information to a computer database when a sample identification label is printed and/or when a blood sample is collected;

(d) testing said blood sample;

(e) selecting a blood unit suitable for transfusion into said patient, wherein said blood unit is marked with a unique blood unit identification code;

(f) printing and applying a compatibility label to said selected blood unit wherein said compatibility label comprises said patient identification information and said blood unit identification code;

(g) reading said patient identification information and said blood unit identification code from said compatibility label;

(h) reading said patient identification information from said wristband, and comparing said wristband patient identification information to patient identification information on said compatibility label;

(i) comparing the blood unit identification code on said compatibility label with the blood unit identification code on said blood unit;

(j) providing a warning if the wristband patient identification information does not match the patient identification information on said compatibility label or if the blood unit identification code on said compatibility label does not match the blood unit identification code on said blood unit; and

(k) transmitting the patient identification read from the patient wristband, the blood unit identification read from the blood unit, and the patient identification and blood unit identification read from the compatibility label to a computer database.

7. The apparatus of claim 6, further comprising a means for retrieving data from the computer database so that information collected with respect to a particular patient or particular blood unit can be reviewed.
