Brief summary

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.

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.

Interventions

BEHAVIORALNurse-practitioner led intervention

* 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.

Intervention model description

This is a quasi-experimental study with non-randomized intervention and control groups. A nurse practitioner (NP) who is trained in diabetes on the oncology team will help manage diabetes for breast cancer patients undergoing cancer treatments. The control group will be enrolled first, followed by the experimental group.

Design outcomes

Primary

MeasureTime frameDescription
Recruitment Success Ratio2 yearsNumber of participants recruited divided by the number of participants approached
Intervention Completion Ratio2 years(Intervention only) Number of participants who completed the intervention divided by the number of participants who were enrolled.
Data Collection Success Ratio2 yearsNumber of participants who completed both surveys divided by the number of participants who were enrolled.
Patient Questionnaire: Self-report of Intervention FeasibilityImmediately post-intervention at the week ~12 follow-upQuestionnaire: 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.
Patient Questionnaire: Self-report of Intervention AcceptabilityImmediately post-intervention at the week 12 follow-upQuestionnaire: 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.
Patient Questionnaire: Self-report of Intervention AppropriatenessImmediately post-intervention at the week 12 follow-upQuestionnaire: 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.
Ratio of Patients Who Had a Summary Document Created for Them at the End of the Intervention2 yearsNumber of patients who had a summary document created for them compared to the number of patients who complete the follow-up visit.
Mean Number of In-person, Virtual or Phone Contacts With the NP Per Participant.2 yearsThis will assess the degree to which the intervention was implemented over the course of the study

Secondary

MeasureTime frameDescription
Change in Patient Self-report Responses of Diabetes Treatment Satisfaction QuestionnaireFrom baseline to week 12 follow-up visitDiabetes Treatment Satisfaction Questionnaire (8 items) DTSQ, score 0-36; higher scores reflecting higher satisfaction
Severity of Patient Self-report Responses of Neuropathy as Measured By the PRO-CTCAE Survey at Follow-upAt week 12 follow-up visitPRO-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
Change in Patient Self-report Responses of Diabetes Distress Scale QuestionnaireFrom baseline to Week 12 follow-upDiabetes 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)
Change in Patient Self-report Responses of the Functional Assessment of Cancer Therapy-Breast QuestionnaireFrom baseline to Week 12 follow-upFunctional 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.
Average Number of Hospitalizations Since Study EnrollmentFrom baseline to Week ~12 follow-upThe average number of hospitalizations since study enrollment
Average Number of ED Visits Since Study EnrollmentFrom baseline to Week ~12 follow-upThe average number of emergency department (ED) visits since study enrollment
Average Number of Uncompleted Chemotherapy SessionsFrom baseline to Week ~12 follow-upAverage number of planned chemo sessions that were not completed by participants
Proportion of Planned Chemo Session Completed (%)From baseline to Week ~12 follow-upThe proportion of planned chemo session completed during study enrollment, as a percentage
Chemo Dose ReductionFrom baseline to Week ~12 follow-upWhether or not participants had their chemotherapy dose reduced
Most Recent HbA1c LevelFrom baseline to Week ~12 follow-upAverage last HbA1c level
Highest Glucose During TreatmentFrom baseline to Week ~12 follow-upAverage highest glucose measure during treatment

Participant flow

Recruitment details

Each week, our study team reviewed multi-disciplinary tumor board lists to identify potential participants. Upon identifying these individuals, every Friday morning we sent the list of patients to the breast medical oncology team for review and approval. By the end of the day on Friday, we received an approved list of patients that we could approach for the study. Our team would then either call the patient by phone or approach them at their next medical oncology appointment.
