Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study investigates if a computer-based clinical decision support tool for skin cancer may improve the diagnostic accuracy of general practitioners (GPs). The aim of the program is to help GPs increase their diagnostic accuracy, in particular regarding the selection of suspicious skin lesions that need biopsy or referral to specialist health care for further assessment. Half of the physicians in the trial will have the clinical decision support tool available during consultations, while the other half has no such tool available. We hypothesize that general practitioners using the clinical decision support tool will have a higher number of correct classifications of skin lesions compared to doctors without the tool.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

General practitioners (GPs) examine patients who attend a primary health care center. In the intervention group the computer-based clinical decision support tool "Nevus doctor" in a first step assists doctors in the process of selecting skin lesions that are suggestive of cancer. In the next step a given skin lesion is photographed using a dermatoscope attached to the lens of the camera. The dermatoscopic image is then processed by the computer program "Nevus doctor" and a preliminary result is presented. Finally the GP reviews the result and assesses the clinical significance of the output by using guidelines presented by "Nevus doctor". The patient is subsequently referred to a dermatologist and a complete skin examination is performed. The assessment of the dermatologist serves as the gold standard.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Nevus doctor clinical decision support

The GPs have access to the clinical decision support tool "Nevus doctor".

Group Type EXPERIMENTAL

Nevus doctor clinical decision support

Intervention Type DIAGNOSTIC_TEST

The computer program analyzes dermatoscopic images. The output is an estimate of the risk of the skin lesion representing skin cancer. The decision support tool helps the doctor to assess the significance of the computer output by taking into account clinical information.

Control

The GPs have no access to the clinical decision support tool "Nevus Doctor".

Group Type NO_INTERVENTION
