Introduction

With the increasing pressure to improve early detection rates of Oral Potentially Malignant Disorders (OPMDs) and oral cancer, leveraging artificial intelligence (AI) in clinical workflows has become a promising strategy. The primary focus of this research is to assess the readiness and potential of AI-assisted diagnosis within the Oral Surgery Department at Colonial War Memorial Hospital (CWMH) in Fiji. This research aims to evaluate existing diagnostic workflows, analyze the practicality of adopting AI-enhanced histopathological methods, explore screening models based on AI, and propose a detailed roadmap for AI integration.

This project is especially important given the global need for rapid, reliable, and objective diagnostic approaches that minimize error and optimize patient outcomes. AI technologies, particularly deep learning methodologies, have shown significant promise in diagnosing complex diseases through image analysis and pattern recognition. For a dental undergraduate research project, the integration of these techniques into routine clinical practice at CWMH may represent a transformative step towards improved early detection and management, potentially saving lives and reducing morbidity.

Research Objectives and Methodology

Objective 1: Evaluate the Current Diagnostic Workflow for OPMDs & Oral Cancer

Overview

The first objective involves a thorough investigation of the current diagnostic practices within CWMH’s Oral Surgery Department. Conducting clinical audits, interviews, and surveys with oral surgeons, pathologists, laboratory technicians, and relevant support staff helps identify procedural strengths and pinpoint critical gaps where errors or delays occur.

Approach

• Stakeholder Interviews: Organize structured interviews with clinical and administrative staff to document each step of the diagnostic process. Questions should focus on current imaging techniques, biopsy protocols, histopathology review, and common bottlenecks.
• Process Mapping: Develop visual flowcharts that illustrate individual diagnostic stages such as patient arrival, clinical examination, imaging, biopsy sampling, slide preparation, histopathological evaluation, and final diagnosis decision points. This mapping aids in identifying areas for potential automation or technology support.
• Data Collection and Analysis: Review retrospective patient records to capture variables such as turnaround times, diagnostic error rates, and follow-up procedures. Analyze the prevalence of OPMDs and the stage at which patients are diagnosed, using quantitative methods like statistical analysis or SWOT (Strengths, Weaknesses, Opportunities, Threats) assessments.

The outcome of this objective will be a detailed report that identifies current inefficiencies, highlights areas prone to subjective interpretation and error, and creates a benchmark against which the benefits of AI integration can be measured.

Objective 2: Analyze the Feasibility of AI in Oral Surgery & Histopathology at CWMH

Infrastructure & Technology

This phase focuses on determining whether CWMH’s existing technological infrastructure can support AI applications. Considerations include the availability of high-performance computing systems, digital imaging devices, and secure data storage capabilities.

Human Resource and Training

Examine the readiness of current staff to transition to AI-assisted methods. Evaluate training needs by surveying the comfort level of clinicians and pathologists with digital tools and automated diagnostic systems. Identify potential gaps and create a training roadmap that would cover both basic AI literacy and specialized equipment usage.

Regulatory and Ethical Considerations

Evaluate the legal, ethical, and regulatory frameworks within Fiji regarding the deployment of AI in clinical practice. This includes compliance with data protection laws, obtaining institutional review board (IRB) approvals, and considering potential patient consent issues. Engage with policy experts to understand how these factors could impact the integration process.

Financial and Logistical Assessment

Conduct a cost-benefit analysis that factors in the cost of AI technologies, potential savings from improved diagnostic efficiency, and long-term financial sustainability. This assessment should include estimates for initial investment in hardware, software licenses, and training programs contrasted against improved patient outcomes and operational efficiencies.

Objective 3: Explore AI-Assisted Screening & Histopathology Models for Diagnosis

Identification of AI Models

Research into existing AI models, particularly those leveraging deep learning algorithms such as Convolutional Neural Networks (CNNs), is crucial. These models have shown great promise in differentiating normal tissue from malignant lesions using histopathological images. Explore available frameworks such as TensorFlow, PyTorch, and machine learning libraries that allow for precise image segmentation and classification.

Data Acquisition and Dataset Development

The success of AI models in diagnosing OPMDs and oral cancer rests on robust training datasets. This involves:

• Image Collection: Capture high-quality clinical photographs and digitized histopathological slide images from patients at CWMH. Ensure that these images are anonymized and ethically sourced.
• Data Annotation: Collaborate with experienced pathologists to accurately label images, ensuring that the training dataset includes clear examples of both normal and malignant tissues.

Pilot Study Design

Propose a pilot study where selected AI models are run on retrospective data. Define measurable endpoints such as accuracy, specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). Rigorous validation using cross-validation techniques and comparing AI outputs with human expert opinions are essential steps.

Integration into Clinical Workflow

Consider how the AI models will coexist with current diagnostic processes. Establish a framework where AI provides a preliminary analysis that is then validated by a human expert. This hybrid approach is crucial in establishing trust among clinicians and ensuring that AI assists rather than replaces human judgment.

Objective 4: Develop Recommendations for AI Integration in Oral Surgery & Pathology

Synthesis of Findings

After thorough evaluations, synthesize findings from the diagnostic workflow analysis, feasibility study, and pilot AI models. Identify key areas where AI has the highest potential for improving diagnostic accuracy and reducing human error. Document both the benefits and constraints observed, ensuring that the recommendations are balanced and evidence-based.

Stakeholder Engagement

Organize workshops or focus groups with dental surgeons, histopathologists, hospital administrators, and IT professionals. Discuss preliminary findings and decision points. Feedback from these sessions is critical in tailoring the implementation strategy to local needs.

Implementation Roadmap and Guidelines

Based on the collected data and stakeholder inputs, draft a comprehensive set of recommendations that include:

• Phased Implementation: Start with a pilot phase targeting specific segments of the diagnostic process. Once the pilot’s success is confirmed, gradually scale up the integration across the department.
• Infrastructure Upgrades: Outline required improvements in digital imaging, computing capacity, and data storage solutions.
• Training Programs: Develop procedures for continuous professional training to ensure that staff are proficient with both AI tools and integrated workflows.
• Quality Assurance Protocols: Establish ongoing evaluation methods to monitor AI performance, ensure data security, and update protocols as necessary.

These recommendations will culminate in a final document that serves as a roadmap for AI integration, highlighting timelines, resource allocations, and measurable outcomes. This document should be dynamic, allowing for iterative updates as new technological advancements or regulatory requirements emerge.
