Study summary

This study aims to determine if an artificial intelligence (AI) medical device can help primary care doctors more accurately identify and manage various skin conditions. Skin issues are a frequent reason for doctor visits, but differences in expertise between general practitioners and specialists can sometimes lead to misdiagnoses or unnecessary referrals.

The researchers hypothesized that the information provided by the AI device would increase the true diagnostic accuracy of primary care practitioners for multiple dermatological conditions. To test this, the study followed a prospective, self-controlled design where each participating doctor served as their own comparison.

During the study, 9 primary care physicians evaluated 30 clinical images representing a variety of skin pathologies. For each image, the doctors followed a two-step process:

  • First, they provided a diagnosis based only on the image and the patient's medical history.
  • Second, they were shown the AI's analysis-including the top 5 suggested diagnoses and confidence levels-and asked to provide a final diagnosis.

The study also investigated if the AI could help doctors decide whether a patient truly needs a referral to a specialist or if the condition could be handled remotely via teledermatology. The primary question was whether using this AI support would significantly increase the number of correct diagnoses made by primary care doctors and lead to more efficient patient care.

Read the detailed description

This detailed description outlines the clinical methodology, technical framework, and data integrity protocols utilized in the investigation of the Legit Health Plus medical device for skin pathologies in primary care.

Study Design and Technical Methodology The research was conducted as a prospective observational and cross-sectional self-controlled study. It utilized a Multi-Reader Multi-Case (MRMC) framework to measure the impact of Computer-Aided Diagnosis (CAD) on clinician performance.

  • Self-Controlled Framework: Each primary care practitioner (PCP) served as their own comparator, providing diagnoses first without and then with device support.
  • Sequential Evaluation Workflow: Participants accessed a secure web-based platform to review 30 clinical cases. For each case, doctors provided an initial diagnosis based on an image and medical history, followed by a final diagnosis after reviewing the AI's top 5 suggested ICD-11 categories and confidence levels.
  • Clinical Decision Support: The study also evaluated clinician decisions regarding dermatology referrals and the feasibility of remote management (teledermatology) based on AI-provided data, such as malignancy indices.
  • Case Distribution: The 30 clinical images represented nine different conditions, including Melanoma, Basal Cell Carcinoma, Psoriasis, and Hidradenitis Suppurativa, all previously confirmed by dermatologists and anatomical pathology.

Quality Assurance and Data Management

To ensure the scientific integrity of the clinical investigation, the following quality and monitoring protocols were implemented:

  • Centralized Case Report Forms (CRF): All data were collected via a secure web platform where entries were time-stamped and stored in a central database.
  • Data Validation and Checks: Validation rules were applied using computer filters to automatically identify missing values or logical inconsistencies. This was supplemented by manual editing and exploratory statistical techniques to detect errors.
  • Monitoring Plan: An independent clinical monitor oversaw the investigation. Monitoring included remote video or telephone meetings every three months to ensure compliance with the Clinical Investigation Plan (CIP) and ISO 14155:2020.
  • Bias Minimization: Random selection of practitioners helped ensure that outcomes were not influenced by pre-existing group characteristics. Standardized protocols ensured all participants were evaluated under identical conditions.

Study population

The study population consists of board-certified healthcare professionals recruited from the clinical fields of general medicine. The participant group includes:

  • Primary Care Practitioners: General practitioners who often serve as the first point of contact for patients with dermatological symptoms.
  • Experience Level: The cohort includes practitioners with at least 5 years of clinical experience in their respective specialities.

Participants were recruited to engage in a remote, web-based evaluation environment rather than being selected from a single physical hospital or town. The clinical images evaluated as part of the study "cases" were sourced from international public dermatology atlases and existing research databases from the sponsor, representing a diverse global patient population.

Inclusion criteria

  • Board-certified primary care physicians regardless of their professional experience.
  • High-quality images of patients with different skin conditions.

Exclusion criteria

Exclusion Criteria:

  • Low-quality images of patients which can not be properly analyzed.

Groups and cohorts

  • Primary Care Physicians

    This group is composed of board-certified healthcare professionals (HCPs) who serve as the "readers" in this multi-reader multi-case (MRMC) study. The cohort is uniquely characterized by its internal comparison: each participant acts as their own control. * The group includes 9 primary care physicians (PCPs), allowing for a comparison of PCPs diagnostic baseline performance. * Interventional Exposure: All participants are evaluated under two distinct conditions: first, providing a diagnosis based solely on clinical images and patient history; second, providing a diagnosis assisted by the AI-based medical device's top 5 suggestions and confidence levels. * Clinical Expertise: Every member of the cohort has a minimum of 5 years of clinical experience in their respective field.

    Device: AI-based medical device for aided diagnosis in dermatological conditions

Interventions

  • DeviceAI-based medical device for aided diagnosis in dermatological conditions

    The intervention consists of a Computer-Aided Diagnosis (CAD) software-only medical device that utilizes computer vision algorithms to analyze digital images of skin structures. During the study, healthcare professionals use the tool as a diagnostic support system to assist in the evaluation of complex dermatological conditions.

What researchers measure

Primary outcomes

  1. Diagnostic Accuracy for Multiple Dermatological Conditions with and without Artificial Intelligence Support.

    This measure evaluates the "Top-1" diagnostic accuracy of primary care practitioners (PCPs). Accuracy is determined by comparing the clinician's identified diagnosis-both before and after receiving the AI's top 5 suggestions-against a confirmed reference standard (confirmed by dermatologists or anatomical pathology).

    Time frame: Day 1

Secondary outcomes

  1. Change in Dermatology Referral Rate Assisted by Artificial Intelligence.

    This outcome validates the percentage of cases that practitioners determine should be referred to a dermatology specialist after reviewing the AI-provided information, including malignancy indices and tool recommendations. The goal is to evaluate if the device helps optimize resource allocation by reducing unnecessary referrals

    Time frame: Day 1

  2. Percentage of Cases Deemed Manageable via Remote Consultation.

    This measure assesses the practitioners' evaluation of whether a case can be confirmed and treated remotely through teledermatology based on the AI analysis. A Pearson's chi-squared test is used to analyze the association between referral necessity and remote consultation feasibility.

    Time frame: Day 1
