Quantification History
EBL method used most often is visual estimation Visual estimation is unreliable and inaccurateUnderestimated as much as 33 to 50 % Institute most accurate methods: Quantification of Blood Loss (QBL)

We’ve always done it this way…
Clinical decisions of when and if resuscitative efforts should begin and to notify other team members of hemorrhage, need to be based on measures and evidenceIt is a matter of patient safety!
Gabel, K. T., & Weeber, T. A. (2012)
QBL BenefitsQBL prompts the Nurse on critical actions No longer rely on flawed, imprecise visual estimationTimely recognition of excessive blood loss leads to initiation blood transfusions and other maternal resuscitative efforts Overestimation can be costly--unnecessary treatments like transfusionsUnderestimation can delay life saving hemorrhage interventions

Recommendations
AWHONN now recommends QBL at every birth
The process is intentional—a formal effort!
No more vague “Guesstimates”
Continues until the patient is stable and is cumulative with hand-off reporting
9
QBL is More Accurate
The goal is not a “perfect, precise” number. There may be some discrepancies from mixing with amniotic fluid, urine, irrigant, etc.However it is more accurate to do some measurements than to rely solely on visual estimates.
Who should determine QBL?
It is a team effort and needs to be standardized.
Some teams designate one member as responsible to measure, orally report, and record.
We will discuss 2 methods.
We should be able to answer: How much blood is in the suction canister (after amniotic fluid)?How much blood is on sponges?How much blood is on the floor/on the table?At regular intervals and cumulatively until the patient is stable (2 to 4 hours post delivery)

Methods
12
RecommendationsWeigh wet materials (with known dry weight); may be done by gathering a group of pads and weighing them all together
TIP: A practical way of measuring blood in laps is to weigh them in groups of 5.
Calculate the gram weight and convert to milliliters.
One gram = One milliliter

Recommendations cont.
Use calibrated under-buttock drapes (at vaginal birth, note the volume of amniotic fluid, urine and stool after birth but before the placenta)
Measure what can be suctioned at CS (less irrigation +AF)

AWHONN’s tips for: Where Do We Begin?
Start by teaching the process that is common for most cases. Begin with vaginal births then scheduled cesareans. Be willing to modify and tweak the process to meet the particular logistics of your facility. Have team meeting to determine how to manage e.g., the STAT cesarean.
18
Vaginal Births: Keep it Simple
For Vaginal Births, begin right after the infant’s birth:
• Note amniotic fluid, urine, etc. in the under-buttocks bag prior to birth. (Applicable if SROM occurs close to birth or amnioinfusion performed.) • RN looks at the bag as soon as OB/CNM has completed the delivery to communicate the amount of blood in the calibrated drape as QBL.

Quantification Tips from AWHONN
Assess amount of fluid in the under buttocks drape prior to delivery of placenta - mark drape or state amount Begin QBL immediately after the infant’s birth PRIOR to delivery of the placenta.Record the amount of fluid collected
Most of the fluid collected prior to birth of the placenta is amniotic fluid, urine, and feces. If irrigation is used, deduct the amount of irrigation from the total fluid that was collected.
Subtract the pre-placenta fluid volume from the post-placenta fluid. Most of the fluid collected after delivery of placenta is blood.Continue QBL 2-4 hrs postpartum

Frequently Encountered Clinical Issues and Responses
(adapted from Bingham & Main 2012 and AWHONN 2014)
IssueProviders believe that their patients are unique; thus, the research does not apply to their specific group of patients.
Many physicians and nurses have only performed EBL. They are not familiar with how to QBL.
AWHONN Response
Distribute key peer-reviewed literature related to the measurement of blood loss to every nurse and physician.
The lack of experience indicates that there is a need for more education tactics with QBL details. 22
23
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
The providers are concerned, on the basis of their training and experience, that if they begin quantifying blood loss they will have higher blood loss levels which might reflect negatively on their practices putting their reputations in jeopardy.
AWHONN Response
Track the number of births quantified and their relationship to early recognition of PPH. Report facts and QBL trends to the physicians and nurses.
24
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“QBL is only needed for cases where a hemorrhage is identified.”
AWHONN Response
Measurement of cumulative blood loss is the goal. Often it is too late when we recognize that the woman has lost too much blood. Perform regular quantification in non- emergency situations to prepare the team for the actual PPH event.
25
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“QBL is not exact and therefore it is not worth doing.”
AWHONN Response
The goal is not a “perfect, precise” number. There may be some discrepancies from mixing with amniotic fluid, urine, irrigation, etc. and this can be measured to some degree. It is more accurate to do some measurements than to rely solely on visual estimates.
26
Issues and Responses cont. (adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“There was fluid already in the canister, just estimating, we forgot it and so it’s just an estimate.”
AWHONN Response
Since irrigation is usually done after the major bleeding is controlled, it may be best to connect to another canister BEFORE irrigating to capture this fluid separately. With continued use, documenting the measures at birth and then ongoing becomes routine practice and there is less forgetting to document.
27
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“With QBL, it is now my responsibility to get it right.” “I used to be in charge and still want the responsibility.”
AWHONN Response
Shared responsibility and accountability is critical to quality patient outcomes. A shared team awareness is needed. It is no one person’s responsibility. It is a TEAM responsibility.
28
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“QBL takes a lot of time.”
AWHONN Response
Teams that do QBL report that it becomes routine and takes very little additional time. Have QBL nurse and physician experts showcase doability of QBL and describe how they successfully performed QBL.
29
Issues and Responses cont.(adapted from Bingham & Main 2012 and AWHONN 2014)
Issue
“It’s going to slow down OR room turnover.”
AWHONN Response
Have scales and dry item lists readily available in every OR. Develop quick methods for totaling/calculating in EMR. Think of the time that will be saved by avoiding a hemorrhage event.

Testimonial
AWHONN recommends measuring blood loss for every woman who gives births in order to reduce denial that leads to delays in women receiving lifesaving treatments. Measuring blood loss makes a un-reliable subjective process much more reliable.

TestimonialWhy do Quantification of Blood Loss in Obstetrics?
When I was practicing in Ohio, a quality improvement project was initiated for reduction of obstetric hemorrhage. I was skeptical about some of the components and somewhat taken aback to having anesthesiologists or nurses telling me what the blood loss amount was. I had been estimating blood loss for years without any problems and did not see the value for the added time and attention that it would take. That is, until the consistent measurements indicated that estimation was not as safe for my patients as measured quantification. Over time, I learned from the literature that estimations were often as much as 50% inaccurate, usually underestimating the true loss. I have heard from nurses, that on day 2 the hematocrit is sometimes low and the patient symptomatic when estimations are used and quantifications ignored. This has made a believer out of me and now, I consistently want to have quantified measurement of blood loss for vaginal and Caesarean deliveries. Quantification is not a perfect measurement but is more accurate than guessing, and with the new tools offered to make the measures more accurate, it is getting better and better. Many of our national organizations are strongly encouraging us to use the most accurate quantifications we can. Recent recommendations have come from working groups comprised of ACOG, CDC, SMFM, and AWHONN, as well as, multiple state perinatal collaboratives that quantitative measures are safer for patients. I think we need to have a culture change in the delivery suite. We have the evidence that early recognition of significant blood loss and early intervention is safer for our patients. We need to get over the old thinking that we are not good at our jobs if there is blood loss and move to the evidence based model that says we are best at our work if we recognize and respond appropriately.

TestimonialWhen it comes to obstetric hemorrhage, denial and delay in recognition can equal maternal death. The uterus can bleed 500-800 cc/minute and within 5 minutes of unrecognized hemorrhage a patient can suffer loss of an entire blood volume along with valuable clotting factors. Signs of hypotension are often masked in healthy patients due to increases in cardiac output and vasoconstriction. Quantification of blood loss in the operating room and labor and delivery room is vital to providing early intervention in recognition and treatment of obstetric hemorrhage.
As medical providers, we need to join together in accurately measuring blood loss as part of the multidisciplinary approach to obstetric hemorrhage. By putting the ego aside and letting go of estimates, we can move towards evidenced based quantification of blood loss to help providers overcome the denial and delay in treatment of maternal hemorrhage.

TestimonialWhen implementing any new initiative among nursing staff it is essential to understand the “why” behind the purpose of implementing the new process/procedure. QBL allows us to have a more accurate clinical picture of blood loss so we can proactively manage our patients rather than reactively manage their symptoms after they are already occurring. Even the most experienced clinicians can have a difference of opinion when it comes to subjective assessment. QBL is the closest we can come to objectively assessing the blood loss post-delivery so we can improve clinical outcomes for our patients.

Summary
For EVERY birth, begin QBL immediately after the infant’s delivery and continue ongoing QBL measurement until bleeding is stable. Cumulative measurement of blood loss is key to early recognition of excessive blood loss for timely initiation of life saving interventions. QBL for all births reduces the incidence of denial of significant blood loss and delayed recognition and initiation of treatment.
