PTXII: Confidence in Detecting Pneumothoraces.

In R4HCR: R for Health Care Research

Confidence in Detecting Pneumothoraces.

Description

Subjective confidence rating in the presence of a pneumothorax (PTX) on X-ray.This dataset represents a subset of one reader's confidence scores, in one phase of the study.

Usage

PTXII

Format

A data frame with 300 observations on the following 2 variables.

response

Indicator for presence 1 or absence 0 of a pneumothorax on X-ray

predictor

Subjective connfidence score (1-8) in the absence or presence of a pneumothorax on a X-ray

Details

The original data consisted of 400 retrospectively collected and de-identified chest X-ray images of patients aged 18 years or older, identified from the CRIS database in Oxford University Hospitals NHS Trust. The study included two reader phases. In the first phase (from which the data is synthesised) readers were asked to interpret the entire dataset over three weeks, recording the perceived presence/absence of a pneumothorax on each image and their degree of confidence on a Likert type scale. A second phase (not included here) repeated the exercise with readers re-interpreting the images with assistance from Artificial Intelligence (AI)
