The compliance with a patient-safety bundle for management of placenta accreta spectrum^†

Abstract

Objective

Our objective was to evaluate the compliance with a patient-safety bundle for placenta accreta spectrum (PAS) by comparing the implementation of the components of the patient-safety bundle in the pre- and post-protocol time periods as a quality improvement project.

Study design

This is a before and after retrospective cohort study as a quality improvement report examining compliance with a multidisciplinary delivery approach for patients with suspected PAS between 2007 and 2018. This bundle involved a multidisciplinary approach with maternal-fetal medicine, gynecologic oncology, intervention radiology, obstetric anesthesia, neonatology, and blood bank. The primary outcome was incorporation of all six of the components of the bundle into a PAS procedure: (1) betamethasone, (2) gynecologic oncology intraoperative consult, (3) preoperative balloon catheters, (4) cell salvage technology in the operating room, (5) vertical skin incision, and (6) fundal or high transverse hysterotomy. Demographic, delivery, and patient outcome data were also collected.

Results

There were 39 patients included in the study, 17 were pre-protocol and 22 were post-protocol. Patients were more likely to have a PAS suspected in the antenatal period during post protocol period (23.5 versus 90.9%, p < .0001), as well as having a placenta previa (35.3 versus 81.8%, p = .003), and receive betamethasone prior to delivery (23.5 versus 86.3%, p < .0001). Patients were delivered at an earlier gestational age in post protocol period (36.8 ± 2.52 versus 33.87 ± 2.4, p = .001). The primary outcome, adherence to all components of the patient-safety bundle, was more likely to occur in the post protocol period (0 versus 40.9%, p < .0001). Maternal and postoperative outcomes were not significantly different between groups.

Conclusions

We have successfully implemented a patient-safety bundle for PAS and have standardized the execution of multidisciplinary management for PAS at our institution.
