| ABSTRACT |
PURPOSE:
The purpose of this study was to verify objectively whether abdominal ultrasonography performed by emergency physicians (EP) in emergency departments (ED) immediately after history taking and physical examination could give effective diagnostic information and to check the feasibility and usefulness of the COUCH method.
METHODS:
From May 1, 2005 to September 30, 2005 we recruited 368 patients who complained of abdominal pain in the ED.
Senior level emergency physicians (EP) conducted history taking and physical examinations, following which they were asked for their suspected diagnosis and their level of confidence (from maximum 5 to minimum 1) regarding each diagnosis. The same EP then performed abdominal ultrasonography (US), using the COUCH method and were again asked for their suspected diagnosis and level of confidence.
We compared the suspected diagnoses and levels of confidence before and after abdominal US by using the t-test.
RESULTS:
A total of 106 patients (55 male, 51 female, average age 35.46+/-18.11 years) were enrolled. The number of patients with a suspected diagnosis of after history taking and physical examination only (2.43+/-0.5) was significantly greater than after abdominal US (1.34+/-0.5) (p<0.01). The level of confidences of suspected diagnosis of after history taking and physical examination only (3.43+/-1.14), by contrast, was less than after abdominal US (4.40+/-1.22) (p<0.01). Each year of postgraduate residents could have the same results after US.
CONCLUSION:
We found that abdominal ultrasonography could give EP more informations for pronouncing a correct diagnosis for patients with abdominal pain in the ED, and the COUCH method could lead the EP to get better training for ultrasonography and to diagnose more rapidly and accurately. |
