This month's issue continues the Journal's series on issues related to education and training in pathology and laboratory medicine. 1 As the practice of medicine evolves and changes, so too must pathology and laboratory medicine. With new knowledge, new types of procedures and tests, and new technologies, the specialty and, consequently, the training programs responsible for producing the next generation of practitioners must continue to adapt. This is hard. Change is hard. This challenge is amplified by the sheer size of the domain we as pathologists aspire to master during training.The maturation of informatics as a defined discipline in the practice of medicine has had an ever-increasing impact on the practice of pathology and laboratory medicine. While the recent decision to make the practice of medical informatics a board-certified specialty might have added a certain level of legitimacy for individuals who have dedicated themselves to informatics, the true benefits of applied informatics for pathology rest in the ability to integrate these concepts and technologies with the core components of the domain.Our specialty has been at the forefront of this transformation because of the dedication and revolutionary spirit of those who chose to pursue it in the past. While these pioneers have advocated for the inclusion of informatics training for nearly 30 years, it is clear that significant challenges remain regarding the exact composition of competencies required by pathologist trainees in informatics and exactly how to integrate this training into the current training paradigm. 2,3 In this issue of the Journal, Rao and Gilbertson 1 identify a major impediment to the training of residents in informatics as the incongruity between the duration of dedicated time allotted (a typical residency rotation) for informatics training and the cadence by which real-world informatics projects progress to completion. They have proposed a longitudinal model of informatics educational engagement consisting of four components-foundation, immersion, refinement, and expertise (FIRE). Their engagement model begins immediately upon matriculation into the residency and extends for the entire period up to graduation. The model proposes to start the education quite broadly (foundation) and allow residents to focus their involvement (immersion) based on their interests, such that it is anticipated that no two residents would necessarily follow the same course of longitudinal engagement. Continuous mentoring and assessments would then aid in refinement of the trainee's competency, with the ultimate potential for an outcome of becoming a subject matter expert. This is an added benefit for trainees, yielding potential to increase their marketability for future employment, not unlike the current trend to pursue subspecialty fellowships. This framework also allows for graduated responsibility, which ultimately manifests, upon expert-level attainment, with direct integration into the operational aspects of informatics for the department.To un...
