About this study

Official title: Optimizing Delivery of Diabetes Management During Breast Cancer Care

The goal of this study is to find a new way to make diabetes care better for patients with breast cancer and diabetes who are currently receiving cancer treatment. We will have two groups, the researchers will decide who is in which group. One group will be working with a nurse who is trained in diabetes care while the other does not. This will allow the investigators to see if having a trained nurse as part of the care team can help improve the care the patients receive.

Read the detailed description

The present study aims to develop a stakeholder-engaged nurse practitioner (NP)-led intervention to improve diabetes care for patients with breast cancer and diabetes who are undergoing cancer treatment.

This is a pilot feasibility study, in which we will use a quasi-experimental pre-post design with non-randomized intervention and control groups. In this feasibility study, the investigators will first enroll 38 eligible patients for the control group and collect effectiveness measures at baseline and follow-up (end of chemotherapy or other cancer treatment, ~12 weeks). Through chart review, the investigators will document cancer treatment regimen completion at follow-up. The investigators will then enroll 38 patients for the intervention group, collecting the effectiveness and implementation outcomes at the end of their treatment (~12 weeks).

The main hypothesis that will be tested in this pilot study is that a nurse practitioner embedded in the oncology team who is trained in diabetes management may successfully manage diabetes during active cancer care for patients undergoing cancer treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nurse-practitioner led interventionBehavioural

    • Face-to-face or virtual consultation with NP during chemotherapy infusion with individualized recommendations/medications AND patient education through the Patient Activated Learning System (PALS).
    • Weekly follow-ups from NP via phone, Zoom, or in-person (patient directed) for 12 weeks/course of chemotherapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recruitment Success Ratio

    Number of participants recruited divided by the number of participants approached

    Measured: 2 years

  2. Intervention Completion Ratio

    (Intervention only) Number of participants who completed the intervention divided by the number of participants who were enrolled.

    Measured: 2 years

  3. Data Collection Success Ratio

    Number of participants who completed both surveys divided by the number of participants who were enrolled.

    Measured: 2 years

  4. Patient Questionnaire: Self-report of Intervention Feasibility

    Questionnaire: Feasibility of Intervention Measure (4 items)

    Response Scale:

    For each item, respondents can choose a value from 1-5. Scales can be created for the measure by averaging responses for all 4 items for the overall score. The average score range is from 1 to 5 with higher scores indicating that the intervention is very feasible, and lower scores (below 3) indicating the intervention is not feasible.

    Measured: Immediately post-intervention at the week ~12 follow-up

  5. Patient Questionnaire: Self-report of Intervention Acceptability

    Questionnaire: Acceptability of Intervention Measure (4 items)

    Response Scale:

    For each item, respondents can choose a value from 1-5. Scales can be created for the measure by averaging responses for all 4 items for the overall score. The average score range is from 1 to 5 with higher scores indicating more favorable attitudes toward the intervention and lower scores (below 3) indicating less favorable attitudes.

    Measured: Immediately post-intervention at the week 12 follow-up

  6. Patient Questionnaire: Self-report of Intervention Appropriateness

    Questionnaire: Intervention Appropriateness Measure (4 items)

    Response Scale:

    For each item, respondents can choose a value from 1-5. Scales can be created for the measure by averaging responses for all 4 items for the overall score. The average score range is from 1 to 5 with higher scores indicating the intervention suits their needs well and lower scores (below 3) indicating the intervention does not fit their needs well.

    Measured: Immediately post-intervention at the week 12 follow-up

  7. Ratio of Patients Who Had a Summary Document Created for Them at the End of the Intervention

    Number of patients who had a summary document created for them compared to the number of patients who complete the follow-up visit.

    Measured: 2 years

  8. Mean Number of In-person, Virtual or Phone Contacts With the NP Per Participant.

    This will assess the degree to which the intervention was implemented over the course of the study

    Measured: 2 years

Secondary outcomes (11)
  1. Change in Patient Self-report Responses of Diabetes Treatment Satisfaction Questionnaire

    Diabetes Treatment Satisfaction Questionnaire (8 items) DTSQ, score 0-36; higher scores reflecting higher satisfaction

    Measured: From baseline to week 12 follow-up visit

  2. Severity of Patient Self-report Responses of Neuropathy as Measured By the PRO-CTCAE Survey at Follow-up

    PRO-CTCAE: Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events

    Neuropathy - PRO-CTCAE (2 items) 0-8 with higher scores representing worse neuropathy

    Measured: At week 12 follow-up visit

  3. Change in Patient Self-report Responses of Diabetes Distress Scale Questionnaire

    Diabetes Distress Scale (17 items) A score of "1" indicates a particular item is not a problem or bother for the patient, whereas "6" represents an item is very concerning for the patient. To score, the patient's responses will be summed and then divided by the number of items in that scale. A mean score of 3 or higher (moderate distress) is considered as a level of distress that is above average. (decrease in score means the item is considered less of a problem/bother)

    Measured: From baseline to Week 12 follow-up

  4. Change in Patient Self-report Responses of the Functional Assessment of Cancer Therapy-Breast Questionnaire

    Functional Assessment of Cancer Therapy -Breast (44-items) measures quality of life for patients with breast cancer. Total scores range from 0-148 with higher scores representing better quality of life.

    Measured: From baseline to Week 12 follow-up

  5. Average Number of Hospitalizations Since Study Enrollment

    The average number of hospitalizations since study enrollment

    Measured: From baseline to Week ~12 follow-up

  6. Average Number of ED Visits Since Study Enrollment

    The average number of emergency department (ED) visits since study enrollment

    Measured: From baseline to Week ~12 follow-up

  7. Average Number of Uncompleted Chemotherapy Sessions

    Average number of planned chemo sessions that were not completed by participants

    Measured: From baseline to Week ~12 follow-up

  8. Proportion of Planned Chemo Session Completed (%)

    The proportion of planned chemo session completed during study enrollment, as a percentage

    Measured: From baseline to Week ~12 follow-up

  9. Chemo Dose Reduction

    Whether or not participants had their chemotherapy dose reduced

    Measured: From baseline to Week ~12 follow-up

  10. Most Recent HbA1c Level

    Average last HbA1c level

    Measured: From baseline to Week ~12 follow-up

  11. Highest Glucose During Treatment

    Average highest glucose measure during treatment

    Measured: From baseline to Week ~12 follow-up
