Av. Sahai et al., An assessment of the potential value of endoscopic ultrasound as a cost-minimizing tool in dyspeptic patients with persistent symptoms, ENDOSCOPY, 33(8), 2001, pp. 662-667
Study Aims: To quantify resource utilization in dyspeptic patients with per
sistent symptoms and to determine whether using both the endoscopic and ult
rasound capabilities of endoscopic ultrasound could reduce costs.
Methods: Consecutive patients with persistent dyspepsia, after a minimum 1-
month trial of acid suppression, underwent endoscopic ultrasound (EUS) and
upper endoscopy using the GF-UM20 echo endoscope. Assuming EUS could replac
e imaging tests which had been requested in addition to upper endoscopy, th
e hypothetical costs of the EUS-based and upper endoscopy-based strategies
were compared.
Results: 116 patients with persistent dyspepsia underwent EUS, of whom 64.6
% had greater than or equal to 2 imaging procedures, most commonly compute
d tomography (CT) (70.6 %) and abdominal ultrasound (64.7 %). The number of
tests did not correlate strongly with any demographic variables. The fiber
optic echo endoscope provided an adequate endoscopic and ultrasound examina
tion but was damaged by retroflexion. Direct hospital costs were lowest for
the EUS-based strategy. Total avoidable cost for 116 patients was $ 4137 t
o $ 14 121 (or $ 36 to $ 122 per patient), depending on whether upper endos
copy was performed in the non-EUS strategies.
Conclusions: Patients with persistent dyspepsia may undergo multiple abdomi
nal imaging procedures. Clinical variables do not predict the need for addi
tional testing. An EUS-based strategy may reduce overall costs if it preven
ts additional testing.
