In this study the investigators will advance research on the development of easy to use
technologies to empower patients. This is a scalable approach that has a significant
potential to reduce suffering for palliative care patients and their caregivers. The
investigators will adapt existing tested empathic conversational agents (ECA) for home-based
cancer care management and inpatient bedside counseling to provide the following functions:
1. medication counseling;
2. physical activity promotion;
3. symptom management and continual screening for adverse events; and
4. alleviation of stress and anxiety
5. spiritual needs assessment; and
6. advanced care planning.
Data from the system will be monitored by a health professional, who communicates with
members of the patient's care team. In this project, this activity will include facilitating
referral for palliative care services.
The investigators will conduct pilot studies both at Boston Medical Center and at
Northeastern University that will test system usability (Northeastern University and BMC) as
well as interview burden (BMC only).
The investigators will conduct a Randomized Control Trial (RCT) to evaluate the agent
technology, comparing usual care (UC) versus usual care plus the agent (UC+ECA) for patients
21 or older, with a life expectancy of < 1 year, from outpatient clinics at Boston Medical
Center (BMC). Each subject will be enrolled along with a caregiver surrogate subject. In
addition to baseline data collection, there will be monthly phone surveys for six months;
intervention subjects will use the system for a six-month period of time. In addition, the
investigators will conduct a randomized trial within the intervention group to compare
subjects getting functions 1-4 (above) versus subjects getting the augmented intervention
with all six functions. The intervention will include a nurse management interface to monitor
clinical alerts generated by the system to stimulate interventions by the clinical staff.

Pilot Study The pilot study will determine usability of the ECA tablet system. Healthy
volunteers will be recruited at Northeastern University, where the system is being developed.
Subjects will spend approximately 60 minutes with the tablet system and provide usability
feedback. Twelve healthy patient volunteers will be recruited to review the system as well as
provide feedback on the relative interview burden (was the interview too long, too invasive,
etc). No identifiable data will be collected from pilot study subjects.
Main Study The study will consist of adults with advanced illness (health care provider
endorses the existence of a potentially life-limiting condition and endorses that "it would
not be a surprise if the patient died within 12 months") who will be randomized to
intervention or usual care control groups. Each person with an advanced illness will be
enrolled along with a caregiver (i.e., family, friend) who will serve as a surrogate subject.
The caregiver will be consented at baseline and interviewed at that point and at the final,
6-month study visit. In addition, if, at any point during their enrollment in the study, the
patient-subject becomes unable, or decisionally impaired, to answer interview questions, the
caregiver will be asked to answer on behalf of the subject.
The patient can be found to be decisionally impaired in any of 3 ways:
1. the patient declares themselves to be unable to answer questions appropriately
2. the patient is unable to pass a brief cognitive assessment that will be administered at
the beginning of each telephone follow-up (per the Brief Screen for Cognitive
Impairment)
3. the patient is physically unable to answer questions on the phone (due to, for example,
serious health decline or death)
Baseline data will be collected after enrollment and before randomization. Baseline data
includes:
1. sociodemographic data
2. Quality of life as measured by the European Organisation for Research and Treatment of
Cancer (EORTC) Quality of Life Questionnaire-Palliative Care
3. Patient Reported Outcomes Measurement Information System (PROMIS) Mental Health
4. Patient Reported Outcomes Measurement Information System (PROMIS) Social Health
5. Patient Activation Measure (PAM)
6. Patient Medication Adherence Questionnaire (PMAQ)
7. Spiritual Needs Assessment for Patients (SNAP)
8. Community Healthy Activity Model Program for Seniors (CHAMPS)
9. a survey of Advance Care Planning (ACP) communication and preferences
10. BSCI (This cognitive assessment is non-exclusionary, but, if the patient scores "0" on
the word recall, the designated caregiver/surrogate will be asked to act as the research
proxy and answer questions for the patient-subject.)
The investigators will also interview the surrogate subject at baseline regarding their level
of caregiver stress with:
1. the CarerQol-7D
2. the caregiver's level of happiness (CarerQol-VAS)
3. self-rated burden (SRB) of care giving After the initial visit, study staff will
administer 5 monthly phone surveys (months 1, 2, 3, 4, and 5), where the EORTC
QLQ-C15-PAL will be collected. At the beginning of each data collection point study
staff will administer the Brief Survey of Cognitive Impairment (BSCI) to determine if
the patient is cognitively able to answer questions, and also inquire about unplanned
health care utilization (i.e., urgent care, emergency room, hospital observation visits,
and hospital admissions).
At the final, 6-month visit, the patient-subject will be interviewed in person, with the
surrogate, and the full list of instruments will be administered. In addition, study staff
will prepare a summary data report for the patient's clinical team. The report will include
obtaining information from the Palliative Care service. The research staff will ask the
subject which clinicians of theirs they would like to have receive this information.
Subjects randomized to the intervention will be given a mini-tablet computer configured for
the purposes of this study. A research assistant will set up the tablet, enroll subjects into
the study database, and train these subjects in the use of the system. Subjects who do not
have existing WiFi at home will be provided with a cellular-based router. In such cases,
study staff will arrange the WiFi service plan, install the router in the home, and confirm
connectivity.
The investigators estimate that in many instances, when a clinician endorses that they would
not be surprised if their patient died within 12 months, that this would be the first time
they solidified a prognostic outlook in their minds for that patient. Stimulating clinicians
to consider their patient's life-expectancy is itself a form of intervention, as this may
instigate communication about prognosis with the patient, a re-evaluation of the treatment
course, assessment of goals of care, and an improved level of attention to symptoms. The
investigators will conduct informational sessions about the study and provide material about
palliative care services in each outpatient clinical environment from which subjects will be
enrolled. Information will be provided on how clinicians can contact the Palliative Care
service to obtain consultation. Clinicians will be encouraged to call for assistance on
palliative care needs for intervention subjects, usual care subjects, and non-subjects.
The same measures collected at baseline will also be collected at the final 6-month
interview. At the end of study participation the investigators will also prepare a summary
data report for the patient's clinical team. The report will include information on obtaining
consultation from the Palliative Care service. The research nurse will ask the subject which
clinicians of theirs they would like to have receive this information.
