Sources of observer variation in dermatologic diagnosis

Observer variation in the diagnosis of superficial oesophageal adenocarcinoma.

BACKGROUND AND AIMS When to perform oesophagectomy for neoplastic progression in Barrett's oesophagus is controversial. Some resect for high grade dysplasia whereas others defer treatment until intramucosal adenocarcinoma is diagnosed. Interobserver agreement for a diagnosis of high grade dysplasia or intramucosal adenocarcinoma remains unknown and may have therapeutic implications. METHODS H...

HRCT diagnosis of diffuse parenchymal lung disease: inter-observer variation.

BACKGROUND This study was designed to measure inter-observer variation between thoracic radiologists in the diagnosis of diffuse parenchymal lung disease (DPLD) using high resolution computed tomography (HRCT) and to identify areas of difficulty where expertise, in the form of national panels, would be of particular value. METHODS HRCT images of 131 patients with DPLD (from a tertiary referra...

Dermatologic Diagnosis: Leukocytoclastic Vasculitis.

Leukocytoclastic vasculitis (LCV), also termed hypersensitivity vasculitis, is a small-vessel vasculitis. The skin is the organ most commonly involved in LCV. Typical presentation is a painful, burning rash predominantly in the lower extremities. The most common skin manifestation is palpable purpura. Other skin manifestations include maculopapular rash, bullae, papules, plaques, nodules, ulcer...

Observer variation in ophthalmology.

Data collected by clinicians and nurses from patients with clinically diagnosed lens opacities revealed that there was poor repeatability of the description of the position of lens opacities, statistically significant observer variation in determining visual acuity, and good repeatability as to what visual tasks the patient can perform. It is suggested that clinicans should give more weight to ...
