Brief summary

This research study is evaluating a new intervention, BOLSTER, which was designed to provide more support for patients with gynecologic and gastrointestinal cancers and their caregivers after a hospitalization.

Detailed description

Hospitalizations can be difficult for patients with cancer, especially when they are transitioning home. Patients and caregivers are often expected to perform complex medical and nursing tasks with little or no preparation. Patients and caregivers report high levels of unmet needs for information about how best to manage symptoms and new medical procedures (such as managing new tubes, lines or drains). The study team has developed a research project which aims to address these needs. If a patient agrees to participate in the study, she will take part in a program called BOLSTER (Building Out Lifelines for Safety, Trust, Empowerment and Renewal). BOLSTER will provide patients and caregivers with education and skills training, symptom management, and support across care settings.

Interventions

BEHAVIORALBOLSTER

BOLSTER provides patients and caregivers with education and skills training, symptom management, and support across care settings over a four-week period.

OTHEREnhanced Discharge Planning (EDP)

EDP provides patients and caregivers a single session of education and skills training, symptom management, and support.

Participant flow

Participants by arm

ArmCount
Phase Ia: 10-week Pre-pilot Patients
In this single arm pre-pilot, patients and caregiver dyads were offered a total of 12 contacts with a BOLSTER study nurse over 10 weeks and daily contact via a smartphone-based symptom app which queries patients about their symptoms using questions from the PRO-CTCAE, risk-stratifies their symptoms, and provides tailored symptom management advice. Participants also had access to web-based symptom management and medical skills training.

Phase Ia: 10-week Pre-pilot Caregivers
In this single arm pre-pilot, patients and caregiver dyads were offered a total of 12 contacts with a BOLSTER study nurse over 10 weeks and daily contact via a smartphone-based symptom app which queries patients about their symptoms using questions from the PRO-CTCAE, risk-stratifies their symptoms, and provides tailored symptom management advice. Participants also had access to web-based symptom management and medical skills training.
6
Phase Ib: 4-week Pre-pilot Patients
The second, abbreviated iteration of the intervention consisted of a single arm pre-pilot, in which patient and caregiver dyads were offered a total of 6 contacts with a BOLSTER study nurse over 4 weeks and daily contact via a smartphone-based symptom app which queries patients about their symptoms using questions from the PRO-CTCAE, risk-stratifies their symptoms, and provides tailored symptom management advice. Participants also had access to web-based symptom management and medical skills training.

Phase II (RCT): BOLSTER Arm Patients
BOLSTER provides participants with longitudinal nursing support across care settings, a smartphone-based symptom management app, a print and web-based symptom management toolkit, and advance care planning to ensure that the patient receives care that is congruent with her informed preferences. BOLSTER includes a total of 6 contacts with a study nurse over 4 weeks. Daily contact via a smartphone-based symptom app which queries patients about their symptoms using questions from the PRO-CTCAE, risk-stratifies their symptoms, and provides tailored symptom management advice.

Phase II (RCT): EDP Arm Patients
Enhanced Discharge Planning (EDP): EDP provides patients and caregivers a single session of education and skills training, symptom management, and support. The EDP participants received medication education, self-management strategies for symptoms, skills training, and a list of red flag symptoms and numbers for who to call.
