ENABLE is an evidence-based concurrent oncology palliative care model that is ready for implementation. It can overcome the barriers created by rural geography and addresses the often unrecognized and unmet needs of the family caregivers. The EIT is an emerging conceptual model for translating evidence into practice. The central core is the linkage between evidence and stakeholders. Successful implementation results from the interaction of Intervention Program/Policy (ENABLE), Implementation Processes (community-based participatory research methods\[CBPR\] within a learning collaborative) and the Practical Progress Measures (RE-AIM). On-going consideration of the Multi-level Context is pivotal to successful implementation. This approach has the potential to have a high impact on reducing disparities resulting from the gap between ASCO recommendations and current oncology and palliative care practices in rural patients and families.

The Urgent Need to Improve Rural Palliative and End-of-life Care for Patients and Caregivers According to the 2010 US Census data, nearly 60 million citizens live in rural or non-metropolitan areas; however, less than 10% of the 833 US palliative care programs are located in rural areas (data provided by the Center to Advance Palliative Care Registry). Rural advanced cancer patients are vulnerable and at high risk of experiencing social isolation and disparities in palliative care due to long distances from treatment centers, low population density, and limited clinical expertise (because rural primary care clinicians and hospices programs have relatively few terminally-ill patients.) Rural location is related to less and later hospice use. Hence, most rural cancer patients are unlikely to have access to interdisciplinary team-based palliative and hospice care recommended by ASCO2 and National Comprehensive Cancer Network guidelines. These patients will lack this expertise or be transferred to a distant site for palliation.6 Patients transferred to distant tertiary care settings are at high risk of spending their last days or weeks of life far from home and loved ones. Conversely, rural patients may suffer during their last weeks or days of life without the benefit of state-of-art treatments of pain or other causes of distress. A US palliative care report card identified rural location as high risk for little access to palliative care. By definition, palliative care includes family caregiver support. An estimated million Americans are informal caregivers defined as an unpaid individual who assist someone with functional impairment with activities of their daily living to some degree. Informal caregiving can have deleterious effects on the caregivers' physical and emotional health; a phenomenon referred to as caregiver burden. A recent meta- analysis showed that cancer caregivers in particular, compared to non-caregiver controls, exhibited higher levels of stress and depression, and lower subjective well-being and physical health. ENABLE includes the evidence-based, caregiver-specific COPE (Creativity, Optimism, Planning, Expert information) intervention, developed by McMillan and colleagues. COPE, based in problem-solving education theory, is designed to improve caregivers' creative problem-solving, realistic optimism, reasonable goal-setting, and knowledge/utilization of relevant resources. Compared to usual care, two weeks post-intervention, caregivers in COPE showed improvements in caregiver burden and overall QOL. COPE is the basis of the ACS caregiving guide and has been adapted for caregivers in other diseases.
