Impact of Electronic Procedural Protocoling on the Timeliness of Pre-operative Breast Localization Procedures.

OBJECTIVE: To evaluate the impact of a new electronic procedural protocol on start times of pre-operative breast localization procedures. METHODS: This HIPAA-compliant, Institutional Review Board-exempted, quality improvement initiative was performed at a large tertiary academic center. In May 2018, an electronic version of the pre-procedure protocol for breast localizations was created within the electronic health record; prior to this time, the protocol was completed manually on a paper form. Mean time between: (1) appointment time and procedure start time, (2) procedure begin-to-end time, and (3) arrival to appointment time were compared for all female patients undergoing pre-operative breast localization procedures during 4-month periods pre-implementation of the electronic procedural protocol (January-April 2018), and post-implementation (June-September 2018), excluding the May 2018 implementation month. Statistical analysis was done by two tailed t-test and statistical process control charting. RESULTS: Pre-implementation, 427 procedures were performed, and post-implementation 409 procedures were performed. Three pre-implementation cases performed more than 3 hours prior to appointment time were excluded (presumed to be rescheduled cases). Mean time between appointment time and procedure start time decreased from 2.7 minutes after to 5.6 minutes before appointment start time, an 8.3-minute improvement (P = 0.0001), with sustained improvement by statistical process control analysis. Mean time for procedure length increased by 4.7 minutes (P = 0.001). There was no significant difference in mean time of patient arrival to appointment time pre- and post-implementation. CONCLUSION: Implementation of an electronic protocol process for pre-operative breast localizations was associated with a significant and sustained reduction in time between appointment time and procedure start time.

MRI evaluation of the placenta from normal variants to abnormalities of implantation and malignancies.

Even though the placenta has been known for millennia, it is still considered one of the most complex and least understood human organs. Imaging of the placenta is gaining attention due to its impact on fetal and maternal outcomes. MRI plays a vital role in evaluation of inconclusive cases by ultrasonography. It enables precise mapping of placental abnormalities for proper multidisciplinary planning and management. In this article we provide a comprehensive in-depth review of the role of antenatal MR in evaluating "The Placenta." We will describe the protocols and techniques used for MRI of the placenta, review anatomy of the placenta, describe MRI features of major placental abnormalities including those related to position, depth of implantation, hemorrhage, gestational trophoblastic neoplasia, and retained products of conception and discuss the added value of MRI in the management and preoperative planning of such abnormalities.
