Does the patient appear acutely or chronically ill? An interobserver study of global assessments of hospital patients.

The general appearance of 201 patients was assessed by a team of observers. Each patient was seen by two experienced physicians, two junior physicians and two medical students who stated whether the patients did not appear ill or whether the patient appeared acutely or chronically ill. The interobserver variation was considerable and the kappa-values ranged from around 0 to 0.75. The level of agreement did not seem to depend on the clinical experience of the observers. One experienced clinician assessed the patients differently from the others.

Interobserver variation in the detection of pulmonary venous hypertension in chest radiographs.

A total of 171 sets of chest radiographs chosen randomly were reviewed independently by two residents in their second year of training, and two experienced radiologists. The degree of interobserver agreement in an overall assessment of pulmonary venous hypertension and in the assessment of five signs, indicative of pulmonary venous hypertension was determined by kappa statistics. The average level of agreement was moderate (0.51-0.56) for the overall assessment and the signs of perivascular clouding, perihilar haze and pleural effusion, and poorer (0.31-0.38) for flow shift and Kerley lines. In the overall assessment agreement between experienced radiologists was slightly better (0.63) than average. Multiple reader interpretation is recommended for the assessment of low-grade pulmonary venous hypertension.

Interobserver variation in the radiographic diagnosis of gastric ulcer. Gastroenterologists' guesses as to level of interobserver variation.

A total of 156 double contrast barium examinations were independently interpreted by two observers for the presence of gastric ulcer. The observed agreement between the two readings was 93 per cent, and after adjusting for the expected chance agreement a kappa value of 0.73 was obtained. At the first reading 4 ulcers, and at the second reading 8 ulcers were interpreted as malignant. None of these interpretations agreed. In a questionnaire study it was demonstrated that gastroenterologists had a realistic impression of the level of agreement in the radiographic detection of gastric ulcer.

Interobserver variation in the radiographic diagnosis of duodenal ulcer disease.

Interobserver variation was estimated in radiologists' detection of duodenal ulcer and deformity of the duodenal bulb. A consecutive series of 156 patients with upper abdominal pain had a double contrast barium examination. The films were first read by routine by a specialist in radiology. A second reading was performed by another specialist who did not know the result of the first reading. Overall agreement between the two readings in the detection of duodenal ulcer and deformity of the duodenal bulb was 0.91 and 0.94, respectively. The overall agreement was adjusted for the expected chance agreement and kappa values were calculated. Kappa was 0.63 for the detection of duodenal ulcer and 0.85 for the detection of deformity of the duodenal bulb.

Accuracy of radiologic and endoscopic diagnosis of gastric ulcer.

Patients with upper abdominal pain are often examined with both double contrast study of the stomach and endoscopy. On the basis of the results of the two examinations four diagnostic criteria of an ulcer can be formed: 1) radiography reveals an ulcer, 2) endoscopy reveals an ulcer, 3) both radiography and endoscopy reveal an ulcer, and 4) radiography and/or endoscopy reveals an ulcer. In a prospective study the accuracy of each of the four diagnostic criteria was examined. Eighty-two randomly selected outpatients had a double contrast barium examination and an upper gastrointestinal endoscopy performed by staff personnel. The diagnosis of a specialist in upper gastrointestinal endoscopy was used as the standard. For the four diagnostic criteria the overall accuracy ranged from 0.80 to 0.88. The predictive value of a positive test result was around 0.70 and the predictive value of a negative test result ranged from 0.81 to 0.96. The specificity ranged from 0.87 to 0.95, and the sensitivity from 0.38 to 0.90. It is concluded that from a clinical point of view, the accuracy of the four diagnostic criteria does not differ to an extent that justifies recommendation of one diagnostic criterion of gastric ulcer rather than the other.

Accuracy of radiologic and endoscopic diagnosis of duodenal ulcer.

On the basis of results of barium examination and upper gastrointestinal endoscopy four diagnostic criteria of duodenal ulcer can be formed: 1) radiography reveals an ulcer, 2) endoscopy reveals an ulcer, 3) both radiography and endoscopy reveal an ulcer, and 4) radiography and/or endoscopy reveals an ulcer. In a consecutive series of 156 patients the accuracy of each of the four diagnostic criteria was determined using the findings of an experienced specialist in upper gastrointestinal endoscopy as a reference. The predictive value of a positive diagnosis (PVpos) for the four diagnostic criteria was 0.63, 0.88, 1, and 0.68, respectively, and the predictive value of a negative diagnosis (PVneg) for all four criteria was around 0.90. The selection of diagnostic criteria should therefore depend on the clinical problem.
