Induction Egfr Tyrosine Kinase Inhibitors Prior To Definitive Chemoradiotherapy In Unresectable Stage Iii Egfr-Mutated Non-Small Cell Lung Cancer, Jacqueline V Aredo, Heather A Wakelee, Angela Bik-Yu Hui, Sukhmani K Padda, Nitin D Joshi, H Henry Guo, Aadel Chaudhuri, Maximilian Diehn, Billy W Loo Jr, Joel W Neal

2020-Current year OA Pubs

INTRODUCTION: Increasing evidence suggests that consolidation durvalumab confers limited benefits for patients with stage III EGFR-mutated NSCLC. Induction or maintenance EGFR tyrosine kinase inhibitors (TKIs) added to concurrent chemoradiotherapy (CRT) may optimize definitive treatment, but there are limited data supporting an induction TKI strategy.

METHODS: We evaluated the efficacy and safety of induction EGFR TKIs administered before concurrent CRT in a retrospective series of patients with unresectable locally advanced EGFR-mutated NSCLC. Circulating tumor DNA (ctDNA) analysis was performed on a patient subset using CAPP-seq and correlated with outcomes.

RESULTS: Of six patients, three received erlotinib and three osimertinib as induction …

Perceptions On Non-Traditional Models Of Fieldwork Supervision, Michelle Forfa, Christine Helfrich, Rebecca Simon

Journal of Occupational Therapy Education

Occupational therapy fieldwork education has historically followed the traditional apprenticeship model, which pairs one student with one fieldwork educator for supervision and guidance through the transformational process from student to entry-level clinician. There is an absence of high-level evidence to support this model as best practice in fieldwork education. Despite data published to endorse alternative supervision models, fieldwork educators (FWEs) appear hesitant to embrace these approaches. The purpose of this investigation was to explore occupational therapy practitioners’ views on the value and challenges associated with the implementation of non-traditional models of supervision during Level II fieldwork education. The study specifically …

Level Ii Fieldwork Educators' Perceived And Experienced Challenges With Using The Collaborative Fieldwork Supervision Model, Oaklee Rogers, Cherie Graves, Tamara Turner, Debra J. Hanson, Marilyn G. Klug

Journal of Occupational Therapy Education

Fieldwork shortages have been noted in the literature for some time. With the ever-changing healthcare system and an increasing number of students in occupational therapy programs, the scarcity of fieldwork placements is dire. Rooted in adult learning principles, the collaborative fieldwork supervision model is one approach to fieldwork education that may alleviate the shortage of placements, while also supporting student learning. This model is designed to have one fieldwork educator supervising two or more students throughout a fieldwork experience. The strengths and challenges of this model are well documented, although it is unclear if the identified challenges are the same …

Exploring Fieldwork Educator Development: Preparation Methods And Support Tools, Pamela Karp, Kelly A. Lavin, Tara Collins

Journal of Occupational Therapy Education

Fieldwork education is a critical piece to professional development and competency in occupational therapy.

Use Of The Subject-Centered Integrated Learning Model And The Occupational Experience Profile To Promote Students' Connections Among Occupation, Self, And The Profession, Adele Breen-Franklin, Karen Atler

Journal of Occupational Therapy Education

Recent research related to occupational therapy education identified the need for a conceptual model to help guide the design and implementation of occupation-centered education. Spurred by this research, the Subject-centered Integrative Learning Model-Occupational Therapy (SCIL-OT) emerged as a model to enable educators and learners to keep the concept of occupation at the center of all occupational therapy education and learning. That work, largely focused on teaching students to connect non-occupation content to occupation (Hooper et al., 2020). However, teaching students about occupation directly can also benefit from using the SCIL-OT model to design learning experiences. The purpose of this paper …

The Development Of A Well-Being Program For Occupational Therapy Graduate Students, Stacy Smallfield, Emma Burry, Kelsey M. Lawrence, Kathy M. Yang, Katherine M. Chin, Hannahmarie Klute

Journal of Occupational Therapy Education

High levels of stress among occupational therapy graduate students have led to the adoption of unhealthy coping habits such as poor nutrition, little exercise, and disrupted sleep. In response, many institutions have explored programming and even curricular changes to support student well-being. However, very few are built upon a strong theoretical foundation to address holistic well-being. Therefore, this paper describes how logic modeling was used to develop a student well-being program based on Facilitating Learning and Occupational Well-Being Using Research-Based Initiatives for Student Health (FLOURISH), a theoretical approach rooted in the Person-Environment-Occupation Performance Model. A well-being program delivered via a …
