Impact of a Blood Conservation Bundle Checklist on Perioperative Transfusion Rates during Myomectomy.

STUDY

OBJECTIVE

The primary objective was to introduce an intraoperative blood conservation bundle (BCB) checklist into clinical practice and assess its impact on perioperative blood transfusion rates during myomectomy.

DESIGN

Prospective cohort study with retrospective control group.

SETTING

A Canadian tertiary-care teaching hospital.

PATIENTS: One hundred and eighty-six women who underwent myomectomy.

INTERVENTIONS: The BCB is a physical checklist attached to the patient chart and consists of evidence-based medical and surgical interventions to reduce intraoperative blood loss. It was introduced in October 2018, and data were collected prospectively during a 12-month period for all open, robotic, and laparoscopic myomectomies at our institution. The primary outcome was the perioperative transfusion rate, and the secondary outcomes included estimated intraoperative blood loss, perioperative complications, readmissions, and BCB usage rates. Data were compared with those of a historic control group for a 24-month period before the BCB introduction.

MEASUREMENTS AND MAIN

RESULTS

In the pre-BCB period, 134 myomectomies (90 open, 31 robotic, and 13 laparoscopic) were performed, and during our study period, 52 myomectomies (33 open, 10 robotic, and 9 laparoscopic) were performed. There was a decrease in transfusion rate from 15.7% (21/134) to 7.7% (4/52) after introduction of the BCB; however, this was not significant (p = .152). The mean estimated blood loss was lower postintervention (491 mL ± 440 mL vs 350 mL ± 255 mL; p <.05) as was the mean delta hemoglobin (-28 g/L ± 13.0 g/L vs -23 g/L ± 11.4g/L; p <.05]. The checklist was used in 92.3% of cases (48/52). There were no differences in intraoperative or postoperative complications or readmission rates.

CONCLUSION

Best practice care bundles can improve knowledge translation of guidelines into care delivery. The introduction of the BCB was successful in reducing intraoperative blood loss during myomectomy at our institution. The BCB is a simple, effective tool that can be easily adopted by gynecologic surgeons to guide intraoperative decision-making during myomectomy.
