About
Danish studies have shown that the majority of palliative cancer patients wish to be cared for and spend the rest of their lives at home. Nevertheless > 50% of palliative cancer patients die in acute hospitals and these figures are found in countries with a highly developed palliative care service as well. Some studies have suggested that, among other causes, delays in the discharge process represent a significant obstacle for achieving care and treatment, and ultimately death at home. Therefore, this randomized controlled trial (RCT) aims at investigating an accelerated transition program from oncological treatment to continuous specialized palliative care at home for patients with incurable cancer. The primary objective of the study is to investigate whether an accelerated transition from oncology care to palliative home care significantly increases home care and death. The secondary objectives are to investigate whether the intervention improves symptom control and quality of life, increases survival, affects health care expenses, improves caregiver quality of life and burden, dyadic coping and grief outcomes. The study will take place in the departments of oncology at Rigshospitalet, where palliative cancer patients will enter the intervention or usual care arms. The intervention is an accelerated transition program, which consists of planning palliative home care and if needed optimization of facilities at home, and a transfer to home care within 5 days of informed consent. On day 1 at home the patient, informal caregiver, nurse, representatives of the specialized palliative care team and if possible the general practitioner and project psychologist meet to organize home care. A dyadic psychological intervention is offered to patients and their informal caregiver during specialized palliative care at home and to bereaved caregivers. The control group will be treated according to the usual principles, but if inadequate palliative care is observed in this group, the study group is obliged to involve responsible professionals. Both groups will be followed by assessments of the patient and the caregiver for up to 6 months and the caregivers 19 month after the patient's death.
Full description
The trial is a controlled, randomized clinical trial in which 340 in- and outpatients in the Department of Oncology, at Rigshospitalet (Copenhagen University Hospital), are randomly assigned to either an accelerated transition process from oncological treatment to continuing specialised palliative care (SPC) at home plus standard care or standard care alone.
Patients are randomized immediately after their consent and will be discharged within a maximum of 5 working days from randomization. If these timelines are exceeded due to practical issues, the patient can participate in the trial if he/she completes a new base-line questionnaire (Quality of life questionnaire - Core (EORTC-QLQ-C30), Edmonton Symptom Assessment System (revised version) (ESAS-r), Hospital Anxiety and Depression Scale (HADS), Symptoms priority list, Symptom Checklist-92 (SCL-92), Medical Outcomes Study Social Support Survey (mMOS-SS), Dyadic Coping Inventory (DCI)and Relationship ladder, and still meets the inclusion criteria.
Data collection from patients and informal caregivers:
Patients are identified, informed about the study and consenting patients and their informal caregivers complete questionnaires (baseline), after which patients are randomized to either the intervention or the control group. The intervention group will be assigned a specialised palliative care team (SPT) no later than 5 days after randomization. The control group will continue their current treatment. Two weeks after baseline, patients and caregivers complete questionnaires for the 2-week follow-up. Likewise, the follow-up at 4 and 8-weeks consists of questionnaires completed by patients and caregivers. Six months after baseline, the patient's vital status is retrieved. If the patient is still alive questionnaires are sent to the patient and caregiver.
In case of admissions of the patients in both groups, data regarding causes of admission are retrieved from medical records.
Throughout the psychological intervention, the psychologists will register the thematic content of the sessions.
Data collection from informal caregivers includes the Medical Outcomes Study SF-36, Symptom Checklist-92 (SCL-92), modified Medical Outcomes Study Social Support Survey (mMOS-SSS), Zarit Burden Interview (ZBI), Dyadic Coping Inventory (DCI), Relationship Ladder, and Experiences in Close Relationships-Short Form (ECR-S). Data collection from caregivers will continue after the patient's death in the form of questionnaires, which are to be completed after 14 days, 2, 7, 13 and 19 months into the bereavement process (Medical Outcomes Study SF-36, Symptom Checklist-92 (SCL-92),Pittsburgh Sleep Quality index (PSQI), modified Medical Outcomes Study Social Support Survey (mMOS-SSS), Inventory of Daily Widowed Life (IDWL), Experiences in Close Relationships-Short Form and Prolonged Grief(PG-13)). Further, data on caregivers' use of healthcare services will be retrieved from the National Health Care Register, National Patient Registry, the Psychiatric Central Register and Medicinal Product Statistics Register. After the last session, short semi-structured interviews will be conducted among a selected group of caregivers to identify the elements of the intervention that were experienced as helpful, and to investigate the caregivers' experience of having cared for their relatives at home and their bereavement process.
Blood samples from a subgroup of caregivers:
To analyze Telomere length, 10-milliliter (ml) blood samples from caregivers will be collected in a heparinized glass before and after the intervention. The white blood cells (leukocytes) are isolated and frozen to - 80 degrees Celsius. Blood samples are taken before randomization and after termination of the intervention. When the investigation is complete and all blood samples have been obtained and frozen, we will follow a standard protocol for isolation of telomere DNA. This protocol describes how DNA is analyzed for TL in the leukocytes by using a quantitative polymerase chain reaction (PCR), and how the total average TL is calculated from both the amount of telomeric product, and each copy gene.
The intervention:
Before the patient agrees to participate, an information meeting will be held. If the patient gives consent to participate, the CRFs will be completed, the blood sample taken from the caregiver and the patient will be randomized. At day one or two after randomization the research nurse, the patient and informal caregiver discuss the patient's wishes for specialised palliative care in their own home and how these can be reconciled with the caregiver's wishes. The patient and caregiver's perceptions of challenges and concerns related to home care are explored and addressed. Immediately after the planning meeting the conditions in the home are optimized, if needed. Four to five days after randomization a home conference is held with the patient and caregiver, representatives of the SPT, nurse, and as far as possible with the patient's GP and the project psychologist. The SPT in collaboration with the GP and district nursing is now responsible for the distribution of tasks related to treatment and care. Patient and caregiver (the primary informal caregiver, appointed by the patient), will be offered a psychological intervention as part of the multi-disciplinary intervention. The psychological intervention will be guided by an intervention manual developed specifically for the study. After the patient's death, bereaved caregivers will be offered one or two additional session, concluding the intervention.
Elements of the psychological intervention:
The psychological intervention will provide a continuum of sessions both before and after the patient's death, so caregivers continue to be supported after the death of their loved ones. The session content will depend on the specific situation and needs of each patient-caregiver dyad. The sessions may thus address several themes that can support the patient in being at home, for example, communication between the patient and the caregiver, reconciliation of different expectations and wishes for being cared for at home, psycho-education about stress and coping and focus on caregivers' self-care. The psychologist may also serve as a navigator in the event of unresolved issues and problems (i.e. help patients and caregivers to identify the most important issues for them and the right people to contact).
The duration of the study:
The study is completed when 340 patients have been randomized into the study and after the last patient has been followed six months after baseline. Patients in the intervention group can then choose to continue with the SPT after the study completion.
Duration of the study of caregivers ranges from randomization to the end of follow-up 19 months after the death of the patient.
In the control group, the patients continue to be attached to the health care system in line with current practice. This means that the patient typically remains in hospital or ambulatory clinic and may have contact with one or more hospitals, GP and possibly homecare later in the process. Caregivers in the control group may receive psychological counseling through referral from a GP.
