BackgroundCough severity represents an important subjective endpoint in assessing the effectiveness of therapies for patients with chronic cough. Although cough-specific quality of life questionnaires exist, a widely available cough severity instrument with established measurement properties remains unavailable.AimsTo identify and summarise the results of studies reporting on the experience of patients with chronic cough and, in the process, develop a conceptual framework to inform development of a patient-reported outcome measurement (PROM) addressing cough severity.ResultsWe identified 61 eligible studies reporting on patient experience with chronic cough. Studies provided 82 potential items, of which 43 proved unique and relevant to cough severity. The urge-to-cough sensation and the cough symptom itself represented broad domains of cough severity. Two subdomains under urge-to-cough included frequency (1 item) and intensity (1 item). Five subdomains under cough symptoms included control (2 items), frequency (6 items), bout duration (1 item), intensity (8 items), and associated features/sequelae (24 items).ConclusionsOur systematic survey and conceptual framework identified items and domains of cough severity in patients with refractory or unexplained chronic cough. The results support item generation and content validity for a PROM assessing cough severity.

Multidisciplinary neuro-oncology clinics allow collaboration between various specialties and training levels. Building a tenable clinical research program based in the longitudinal dialogue and practice of collaborative clinicians and trainees can bridge clinical observations to research execution. However, forming a research team around a multidisciplinary clinic’s activities is constrained by a lack of literature or guidelines. As well, challenges in sustaining team logistics, communication, and productivity can persist without a standardized team framework. This perspective discusses the state of research teams in clinical oncology, and uses experiences from the McMaster Pediatric Brain Tumour Study Group to guide those seeking to form a research team based on the collective activities and observations of a multidisciplinary clinic.
