Abdominal pain (AP) is a common presenting complaint in emergency depa
rtment (ED) patients, A 1972 study reported that unsupervised surgical
residents in a university hospital ED were unable to make a specific
diagnosis in 41% of 1,000 AP patients. In the intervening time, ED ava
ilability of diagnostic technology has increased, and the reference ho
spital acquired full-time emergency medicine (EM) faculty. To assess w
hat changes occurred in the evaluation and epidemiology of AP, a simil
ar study was done at the same hospital. The study design was a review
of records of 1,000 consecutive ED patients with AP seen in 1993 at a
58,000-visit public Level I trauma center ED, The percentage of ED pat
ients (4% to 5%) with AP was unchanged. Frequency of hospital admissio
n dropped from 27.4% (1972) to 18.3% (1993), There was marked increase
in the specificity of diagnoses, with only 24.9% in 1993 diagnosed as
undifferentiated abdominal pain (UDAP). There were eight cases of mis
sed appendicitis in 1972 and none in 1993, One 1993 patient with acute
cholecystitis was initially misdiagnosed as having UDAP. Advances in
technology and EM faculty presence were temporally associated with imp
roved diagnostic accuracy in patients with AP in a university hospital
ED. As compared with 20 years ago, fewer patients required hospitaliz
ation, more were assigned a specific diagnosis, and there were fewer G
ases of missed surgical disease. Copyright (C) 1995 by W.B. Saunders C
