Trial Outcomes & Findings for Single-arm Phase II Study of NDURE for Patients With HNC (NCT NCT03821064)

Results Overview

Percent of patients who start PORT \>6 weeks after surgery. Initiation of postoperative PORT \> 6 weeks after surgery is defined as more than 42 calendar days from the time of the definitive surgical resection to the initiation of radiation therapy. In situations in which the surgical management of the primary tumor and the neck are staged (i.e. occur on two different calendar days), the date of the surgery for the primary tumor will be used. In situations in which an additional surgical resection is required (e.g. re-resection of positive margins to clear residual disease), the date of the earlier (i.e. attempted definitive) surgical procedure will be used to determine the target start date for PORT.

Measure	NDURE (Patient Navigation) NDURE is a theory-based, multi-level patient navigation (PN) intervention consisting of clinic-based sessions of manualized PN to reduce barriers to care, increase HNC care delivery, and improve clinical outcomes (timely, equitable PORT). NDURE will be delivered from surgical consultation to PORT initiation (\~3 months). The three in-person NDURE sessions, which are expected to take 30-60 minutes each, will coincide with the presurgical consult, hospital discharge, and 1st postoperative clinic visit. During the first session, the navigator will 1) elicit barriers and facilitators to timely PORT, 2) develop the personalized barrier reduction plan (BRP), review the BRP with the patient, caregiver, and provider, and 3) implement the BRP. At the two subsequent sessions, the navigator will review and update the BRP in an iterative, dynamic fashion, identifying new barriers and systematically tracking resolution of prior barriers until the start of PORT.

Population: ITT- 3 participants did not complete the questionnaire

The Communication and Attitudinal Self-Efficacy Scale for Cancer-12 (CASE-cancer) measures self-efficacy within the context of productive communication and positive attitude for cancer patients. It is a psychometrically sound tool that may provide new information on important mediating factors of cancer care. The response scale ranges from 1 to 4 points (1= strongly disagree, 2=slightly disagree, 3=slightly agree, 4=strongly disagree). The twelve question scale is divided into 3 domains with 4 questions each. Scores from these subscales are added to compute a total score ranging from 12-48. Higher values represent a more positive attitude.

Care Transition Measure-15 (CTM-15) is a validated, psychometrically sound 15-item, unidimensional measure of care transitions across the healthcare system that is consistent with the concept of patient-centeredness and useful from an organization perspective for the purpose of performance measurement and quality improvement. Items are rated on a 4-point Likert scale from 'Strongly Disagree' (1) to 'Strongly Agree' (4). The CTM-15 score is calculated as the mean score (the summed score from each question divided by the total number of questions) with a linear transformation to 100. Scores range from 0-100; higher scores reflect more care integration and better care transitions.

Measure	Patient Navigation n=7 Participants Patient Navigation: NDURE is a theory-based, multi-level patient navigation (PN) intervention consisting of clinic-based sessions of manualized PN to reduce barriers to care, increase HNC care delivery, and improve clinical outcomes (timely, equitable PORT). NDURE will be delivered from surgical consultation to PORT initiation (\~3 months). The three in-person NDURE sessions, which are expected to take 30-60 minutes each, will coincide with the presurgical consult, hospital discharge, and 1st postoperative clinic visit. During the first session, the navigator will 1) elicit barriers and facilitators to timely PORT, 2) develop the personalized barrier reduction plan (BRP), review the BRP with the patient, caregiver, and provider, and 3) implement the BRP. At the two subsequent sessions, the navigator will review and update the BRP in an iterative, dynamic fashion, identifying new barriers and systematically tracking resolution of prior barriers until the start of PORT.

The ISEL-12 is a validated, 12-item assessment of three subscales (appraisal, belonging, and tangible) that has been used to assess support in prior PN studies. Items are rated on a 4-point Likert scale from 'Definitely False' (1) to 'Definitely True' (4). The total score is calculated by summing scores across all items (with reverse coding for items 1, 2, 7, 8, 11, 12). Scores range from 12-48. Higher scores indicate more support.

The Perceived Susceptibility Questionnaire is modified version of a validated 3-item perceived susceptibility subscale for mammography screening to assess perceived susceptibility for delays starting PORT after HNC surgery. Items are rated on a 5-point Likert scale. Scores range from 3-15 with higher scores indicating higher perceived susceptibility.

The IPQ-R consequences subscale is easily modifiable to asses disease-specific perceived severity. The IPQ-R is a validated assessment of a patient's self-representation of the health consequences of their illness. There are 6 Items; each is rated using a 5-point Likert scale from 'Strongly Disagree' (1) to 'Strongly Agree' (5). The score is calculated by summing across all items (with reverse coding for item 3). Scores range from 5 to 30. Higher scores indicate a greater degree of perceived severity of the illness.

The Perceived Barriers Questionnaire is a self-report measure of the presence/absence of pre-specified barriers to cancer care (yes/no). The questionnaire has been used extensively to assess perceived barriers in prior PN studies. Scores range from 0-29; higher scores reflect a greater number of barriers to care
