    Head and Neck Cancer Survivors' Exercise Preferences and Barriers Before and After Participation in an Exercise Intervention
    (2016) Jackson, Colleen; Culos-Reed, S. Nicole; Lau, Harold; Bridel, William; Pelletier, Guy; Moules, Nancy
    Purpose: This study examined the exercise preferences and barriers of head and neck cancer (HNC) survivors in relation to exercise experience. Methodology: Participants from the ENHANCE trial (n=22) completed questionnaires on exercise preferences and barriers, which were further explored in semi-structured interviews with a subset of participants (n=17). Results: Before participation in the ENHANCE program, lack of interest and time were the primary exercise barriers. After participation, there was a significant decrease in typical barriers including lack of interest (p=.008)), exercise not a priority (p=.039), and not in routine (p=.004). Participants also reported significant increases in preferences for engaging in exercise at a cancer centre (p=.031), and with other survivors (p=.016). Four higher-order themes emerged from interview data analysis pertaining to preferences (exercise types, company, supervision, and logistics), and three higher-order themes regarding barriers (physical, psychological and external). Significance: The results identify key factors for effective HNC exercise program design.

    The feasibility of patient-reported outcomes, physical function, and mobilization in the care pathway for head and neck cancer surgical patients
    (2022-05-27) Daun, Julia T.; Twomey, Rosie; Capozzi, Lauren C.; Crump, Trafford; Francis, George J.; Matthews, T. W.; Chandarana, Shamir; Hart, Robert D.; Schrag, Christiaan; Matthews, Jennifer; McKenzie, C. D.; Lau, Harold; Dort, Joseph C.; Culos-Reed, S. N.
    Abstract Background Head and neck cancer (HNC) patients are an understudied population whose treatment often includes surgery, causing a wide range of side effects. Exercise prehabilitation is a promising tool to optimize patient outcomes and may confer additional benefits as a prehabilitation tool. The primary objective of this study was to assess the feasibility of measuring patient-reported outcomes (PROs), physical function, and in-hospital mobilization across the HNC surgical timeline in advance of a future prehabilitation trial. The secondary objective was to examine potential changes in these outcomes across the surgical timeline. Methods HNC patients scheduled to undergo oncologic resection with free-flap reconstruction completed assessments of PROs and physical function at three timepoints across the surgical timeline (baseline, in-hospital, and postsurgical/outpatient). Mobilization was measured during the in-hospital period. The feasibility of recruitment and measurement completion was tracked, as were changes in both PROs and physical function. Results Of 48 eligible patients, 16 enrolled (recruitment rate of 33%). The baseline and in-hospital PROs were completed by 88% of participants, while the outpatient assessments were completed by 81% of participants. The baseline and in-hospital assessment of physical function were completed by 56% of participants, and 38% completed the outpatient assessment. Measuring in-hospital mobilization was completed for 63% of participants. Conclusion Measuring PROs and in-hospital mobilization is feasible across the surgical timeline in HNC; however, the in-person assessment of physical function prior to surgery was not feasible. A multidisciplinary collaboration between exercise specialists and clinicians supported the development of new clinical workflows in HNC surgical care that will aid in the implementation of a future prehabilitation trial for this patient population.
