Evaluation of OB/GYN pathology

Study	Year	Findings	CHEERS score (max 24)
Hazlett [41]	1996	Transvaginal US is cost-saving compared to transabdominal as an initial test in the work-up of pelvic pain in the ED with the exception of patients in the second or third trimester of pregnancy with a palpable abdominal mass or with a full bladder	6
Durston [42]	2000	Initial POCUS by ED physicians in rule-out ectopic cases is cost-effective compared to initial radiology department imaging, although this may delay care in those with adnexal mass or tubal rupture	12
Al Wattar [43]	2014	Twenty-four hour US coverage for OB/GYN emergencies can avert admissions and cost-savings depends on volume	4
