![Page 7: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/7.jpg)
Always make sure the sample is labeled for the right patient
AT THE BEDSIDE with at least 2 patient identifiers
Name IC no
![Page 8: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/8.jpg)
Best practice 1
Identify and inform patient Draw blood sample Label sample by
handwriting at bedside Collect or print sticker
label Check printed label
matches handwritten details before pasting on sample tube
![Page 9: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/9.jpg)
Best practice 2
Print the patient’s sticker label
Identify correct patient
Inform patient (the need for transfusion)
Draw blood sample
Check label with patient
Stick label (at bedside)
![Page 10: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/10.jpg)
Case 2
B/O RR, premature infant @ 27 weeks
Day 13 OL on ventilator
14th April 2011 @ 1235h: received GXM request
Grouped as AB Rh pos
Previous record: group O Rh positive
Re-grouping with second sample: AB Rh pos
![Page 11: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/11.jpg)
Case 2 – cont’d
Possible explanation: 1st grouping was wrong
So BB staff went up to the ward
Bedside grouping: group O Rh positive
So what happened?
![Page 12: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/12.jpg)
Case 2 – cont’d
What actually happened:
1st sample: Doctor A took blood sample Doctor B labeled the sample Doctor C filled and signed the request form
2nd sample: Doctor D took an unlabeled sample from
the fridge and sent to BB
![Page 13: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/13.jpg)
The SAME doctor or staff who draws the blood sample must also label it
At the bedside
![Page 14: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/14.jpg)
Just imagine if there was no previous record and this was a new patient
If this was an older child, he would have been transfused with AB blood when he is actually group O!
![Page 15: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/15.jpg)
Case 3
28th March 2011: received a GSH sample for Supramaniam A/L Kannan
Grouped as A Rh pos
Previous record: Group O Rh pos
So what went wrong?
![Page 16: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/16.jpg)
Case 3 – cont’d
There were 2 patients with the same first name in the ward
1.Supramaniam A/L Kannan Bed 16
2.Supramaniam A/L Solamalai Bed 23
Bedside grouping Patient 1: Group O Rh pos Patient 2: Group A Rh pos
![Page 17: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/17.jpg)
Case 3 – cont’d
What went wrong:
Doctor A: filled the request form
Doctor B: drew the blood sample from the wrong patient
Doctor A: labeled the sample
![Page 18: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/18.jpg)
How do we prevent errors?
Correct practice at every step
![Page 19: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/19.jpg)
Step 1: the decision to transfuse Avoid inappropriate and unnecessary
transfusions
Inform patient
Fill up request form
Ask patient for blood group if known
![Page 20: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/20.jpg)
Step 2: correct patient identification (prior to blood sampling)
Ask the patient his/ her full name and identification card no. (DOB and MRN)
Check the wrist band (in-patient) or hospital card/ ic (daycare)
![Page 21: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/21.jpg)
Step 3: blood sampling
NEVER pre-label GXM tubes (EDTA) The SAME doctor/ staff must take blood
sample and label the tube NEVER use pre-printed labels Show labeled tube and completed
request form to patient NEVER take blood samples from >1
patient at a time
![Page 22: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/22.jpg)

Step 4: receipt of blood request BB staff must
make sure sample and request form are properly and correctly labeled
check for any previous transfusion record
![Page 24: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/24.jpg)
Step 5: collection of blood
Bring collection slip and blood box BB staff must check collection slip matches
request form and blood to be collected Withdrawal of units must be documented
Staff name Date Time issued
Inspect colour and expiry date
![Page 25: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/25.jpg)
Collection slip
Blood box ± ice
![Page 26: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/26.jpg)
Clotted red cell Bacterially contaminated platelets
INSPECT – accept or reject?
![Page 27: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/27.jpg)
Step 6: correct patient identification at bedside (prior to transfusion) Conscious patient
Ask patient’s full name and ic no.
Check against wrist band
Ask for blood group type if known
Check patient ID, form, blood unit and PPDK card matches
Unconscious patient Check wrist band Check patient’s
notes/ IC
Check patient ID, form, blood unit and PPDK card matches
Double check by second person
![Page 28: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/28.jpg)
Bedside check
![Page 29: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/29.jpg)
Step 7: monitoring vital signs
Transfuse blood/ components promptly (after correct bedside patient identification)
Check T0, BP and PR prior to transfusion
Re-check vital signs first 15 minutes and ½-1 hourly
Fill PPDK card AFTER completion of transfusion
Return PPDK card with used blood bags to BB
![Page 30: Module 7: Errors in transfusion Transfusion Training Workshop KKM 2012.](https://reader034.fdocuments.in/reader034/viewer/2022051416/56649e5e5503460f94b57ffb/html5/thumbnails/30.jpg)
Monitoring vital signs Prior to transfusion Periodically
thereafter

Wrong blood – wrong patient
The single most frequent error resulting in ABO-incompatible transfusion is the administration of properly labeled blood to a recipient other than the one intended

Major risks of transfusion
The major risks of transfusion currently lie in the clinical use of blood in hospitals, rather than with transmission of infectious agents through the supply

Inappropriate and Unnecessary (I&U) transfusions Hébert et al:
unnecessary transfusions: 4 to 66%

Back to basics – key lesson
An emphasis again on the importance of the essential steps of the transfusion process: taking the blood sample from the correct patient correct laboratory procedures issuing of the correct component and identification of the right patient at the bedside at
the time of transfusion Identification of the correct patient remains a
key issue and that this must become a core clinical skill

The next time you decide to transfuse
Stop, think and ask yourself …
Is it really necessary?
