Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Can model-prompted risk classifications be incorporated into clinician workflows to enable informed clinical decision-making?
* What are clinicians' perceptions of the information from model outputs, and do they change their decision about data already available to them as a result of the model-prompted risk classification (i.e., to re-review or further assess patients identified by the models as being higher risk)?
Participating radiation oncologists will receive the risk prediction from the model and be asked to complete a survey to give feedback on how they used the prediction in their decision-making.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The current process for clinical/translational researchers within Princess Margaret Hospital (PM)/University Health Network (UHN) to analyze imaging data involves extensive manual curation consisting of interactions with electronic databases and analysis tools to: identify patients with imaging data; collect that data; delineate targets of interest manually (minutes-to-hours per patient); analyze targets based on manually-selected images; and then correlate the analyzed images with clinical information sources (e.g. outcomes or correlative data). Thus, projects with large patient numbers often encounter insurmountable obstacles that limit research productivity.
MIRA (an in-house developed programming toolkit) solves a common problem for all researchers at PM/UHN studying diagnostic, radiotherapy treatment planning, and/or on-treatment imaging by providing a consistent automated analysis environment for these data. MIRA also enhances ethics approved studies with direct linkage to real-time clinical data including diagnostic imaging via collaboration with the Joint Department of Medical Imaging, radiation oncology treatment planning information, and daily radiation oncology on-treatment imaging. The MIRA Clinical Learning Environment (MIRACLE) quality improvement project intends to use the MIRA platform to develop automated clinical pipelines to address three specific study aims:
To identify lung cancer patients with undiagnosed underlying inflammatory lung disease (ILD) from pre-treatment diagnostic images
To estimate individual patients' tumor growth-rate between diagnostic and treatment planning images (specific growth-rate, SGR)
To provide each patient with an estimate of dynamic radiation treatment toxicity risk using radiation treatment planning information, while continuously updating risk estimates using daily cone-beam computed tomography (CBCT) images routinely obtained before each radiation treatment.
MIRACLE is linked safely to active clinical data repositories and has the potential to directly impact daily cancer treatment decisions by making existing imaging data findable, rapidly accessible, interoperable, and reusable for both clinical and research analysis by end users including the physicians caring for lung cancer patients, and cancer researchers. This facilitates evaluation of novel imaging research findings in large patient numbers for clinical and research use. The MIRACLE project's goal is to specifically demonstrate the clinical implementation feasibility of automatically linking and analyzing clinical imaging data alongside clinical outcome; ultimately, helping to deliver value-based healthcare via better patient selection (ILD/SGR) and monitoring/adjusting treatment to decrease toxicity (CBCT).
Feedback from the participating radiation oncologists will be gathered to assess the feasibility and effectiveness of showing patient-specific insights for inflammatory lung disease (ILD), a specific tumour growth rate greater than 0.04 (SGR) and cone-beam computed tomography system (CBCT) changes to clinicians at the point of care. The analysis will help to understand clinicians' perceptions of information provided to them from the model regarding ILD prediction, SGR and lung density changes over the QI period and whether clinicians changed their decision about data already available to them as a result of the model-prompted risk classification (i.e., to re-review or further assess patients for ILD, SGR and CBCT changes based on those patients highlighted by the model as being higher risk).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ILD Silent Mode
The ILD model will be run on patients undergoing routine treatment planning imaging where the notification is sent to the study team for a period of one month to ensure the pipeline is operating as intended.
Application of ILD prediction machine learning model to planning imaging
The ILD prediction machine learning model will be applied to the treatment planning imaging of lung cancer patients receiving radiation therapy (RT). The model will score the risk as high risk or low risk for having underlying ILD.
ILD Prospective Mode
Following successful silent mode, the ILD model will be run on patients undergoing routine treatment planning imaging and the notifications will be sent to the treating physician to incorporate into their workflow.
Application of ILD prediction machine learning model to planning imaging
The ILD prediction machine learning model will be applied to the treatment planning imaging of lung cancer patients receiving radiation therapy (RT). The model will score the risk as high risk or low risk for having underlying ILD.
Routine, automatic presentation of ILD risk level for evaluation by the clinician.
Participating clinicians will be provided with an ILD risk estimate for all lung cancer patients receiving RT who are deemed potentially high-risk based on the model. In these cases, the clinician will receive an email identifying the patient medical record number (MRN) and 'potential high-risk for ILD' flag. Clinicians will then be able to decide whether, based on the information, they want to reassess the patient for ILD prior to starting treatment. Clinicians will also be presented with a short survey each time they are sent an email for a potential high-risk for ILD case so the study team can better understand how that information was used, if at all.
SGR Silent Mode
The SGR model will be run on patients undergoing routine treatment planning imaging where the notification is sent to the study team for a period of one month to ensure the pipeline is operating as intended.
Application of SGR machine learning model to diagnostic and planning imaging
The SGR machine learning model will be applied to the imaging of lung cancer patients with node negative lung cancer receiving stereotactic RT. The automatic calculation will compare target lesions on the patient's diagnostic images with those same lesions on treatment planning images.

Routine monitoring of lung density changes during the course of treatment presented to clinician.

This measurement will be presented to the clinical team, who will then be able to decide, based on the information, how they want to address and track relevant outcomes such as pneumonitis. Additionally, this information may provide the clinical team with feedback about the lung reaction occurring as a result of treatment. Density changes will be documented and monitored for future validation studies, which are outside of the scope of this application.
