Objective: The objective of this retrospective study was to determine the clinical value of performing after-hours ultrasound in patients in the emergency department as well as those who have been admitted to the hospital who have overnight urgent and emergent ultrasound requests. Specifically, we wanted to see if breast ultrasound after hours impacted clinical outcomes of breast intervention or surgery.

Materials and Methods: We retrospectively reviewed the electronic medical records and radiology images of patients who were evaluated with after-hours breast ultrasound for clinically suspected breast abscesses between January 1, 2011, and December 31, 2015 at our institution. After hours was defined as occurring between the hours of 4:30 pm and 7:00 am on weeknights and during the weekend.

Results: A total of 50 patients were included in the analysis. The median age was 51 years (range, 13–73 years). Of these 50 patients, 16 (32%) presented to the emergency center, 22 (44%) were inpatients, and 12 (24%) were outpatients. A total of 10 (20%) patients had abscesses on ultrasound, 10 (20%) patients had nonspecific fluid collections, and 30 (60%) had normal ultrasound findings. Of the 20 patients who had abnormal findings (abscess or fluid collection) on ultrasound, seven (35%) underwent an after-hours drainage procedure that same night. Patients who had abnormal ultrasound findings had a significantly higher chance of needing an after-hours drainage procedure (7/20 vs 0/30, p = 0.0008 by Fisher exact test).

Conclusion: Our analysis of the data suggests that after-hours ultrasound in the diagnosis of breast abscess is a useful clinical triage tool to distinguish patients who would benefit from after-hours intervention from those who can be managed more conservatively.
