Modernizing Rapid On-Site Evaluation: Telecytology Solutions for Efficient, Scalable, and High-Quality Cytopathology

As the demand for rapid and accurate cytologic evaluation grows across distributed healthcare systems, the traditional in-person model for rapid on-site evaluation (ROSE) is no longer scalable. 

Institutions have addressed this challenge through telecytology, taking advantage of live-view digital microscopy to support ROSE remotely. By adopting a browser-based system requiring minimal hardware, clinical laboratories can provide timely cytopathology services across multiple locations, with potential for integration into broader digital pathology workflows.

ROSE is a critical service that ensures adequacy of cytology specimens during procedures such as fine needle aspiration (FNA) and image-guided core biopsies. It allows for immediate feedback to interventionalists and minimizes the need for repeat procedures. Historically, ROSE has depended on on-site cytopathologists or trainees who travel between procedure rooms or even campuses, often leading to inefficiencies and resource strain.

Challenges for rapid on-site evaluation

Cytopathology teams frequently face the complexity of covering multiple FNA sites spread over a geographic area. With increasing demands and decreasing on-site personnel, a telecytology model for ROSE using live digital slide review reduces the need for physical presence while maintaining diagnostic quality.

Cytopathology teams are increasingly expected to:

• Support more procedures across multiple, often geographically separated, locations.
• Operate with fewer resources, including trained pathologists, screeners, and support staff.
• Maintain high diagnostic standards in a remote context.
• Deliver near real-time diagnoses to guide clinical decisions.

The traditional in-person ROSE model cannot scale effectively under these pressures. Delays, overextended staff, and inefficient reporting mechanisms compromise patient care and laboratory performance. Furthermore, newer remote sites (particularly in rural areas) lack cytology infrastructure and cannot justify full-time cytopathology teams.

Telecytology with live view imaging

Deploying a telecytology system that enables both whole-slide imaging and live-view digital microscopy can address these challenges. To have the broadest appeal and utility for a variety of laboratories and use cases, solutions should include the following attributes: 

• Minimal hardware requirements: A digital slide imaging system and an existing network computer at the remote site.
• No custom software: The system should operate via a secure, browser-based platform.
• Scalable and portable: The setup is easily moved between sites or installed in locations with limited space.
• Minimal technical burden: Only requires a technician to prepare and load the slide; no slide movement or objective adjustment is needed remotely.

Validation and quality assurance

A rigorous validation protocol can ensure clinical equivalency between telecytology and on-site evaluation. Important characteristics of a validation procedure should include:

• Visual validation of image quality and completeness.
• Documentation of diagnostic accuracy by remote reviewers.
• Verification of technical staff competency in highlighting areas of interest and slide preparation.

As a result of validation and quality assurance efforts, institutions may note improvements in slide quality due to real-time feedback, enhanced diagnostic consistency, and greater staff satisfaction. 

Conclusion: Expanding remote on-site evaluation options

Telecytology has proven to be a sustainable and effective solution for expanding ROSE services without compromising quality. Live-view digital microscopy can deliver high-quality cytologic evaluations in real time, even at remote sites. 

By eliminating the need for on-site pathologists and complex scanning workflows, this approach is particularly valuable for institutions looking to:

• Reduce diagnostic delays
• Optimize limited human resources
• Expand service coverage to underserved or remote locations
• Integrate remote pathology into broader telemedicine strategies
