1.Know key elements of bundle construction.2.Define palliative care in the context of a bundle project.3.Apply the bundle method to a key hospital palliative care initiative. The Greater New York Hospital Association (GNYHA) Palliative Care Leadership Collaborative (PCLC) brought together 35 hospitals across the greater NY region to implement and measure the impact of a standardized set of best practices for palliative care. Participating hospitals selected a cohort of patients on which to focus their efforts, develop and institute a process for identifying those patients, apply a set of actionable care and treatment guidelines, and document the provision of key palliative care services. These elements of the palliative care “bundle” were consensus-derived by an advisory group comprised of a subset of GNYHA's Palliative Care Leadership Network, a forum of regional palliative care experts. Hospital teams, with the support of GNYHA staff, shared best practices and educational resources, as well as supported one another in overcoming common challenges and barriers, through didactic learning sessions, conference calls, data collection, and analysis to measure progress. The aim of the PCLC is to help hospital teams build sustainable and entrenched palliative care programs, increase their capacity to identify and provide palliative care services to all appropriate patients, and comply with laws regarding palliative care, and to poise them to seek advanced certification status from The Joint Commission. During this session, we will share methodology, results, and lessons learned from this 2-year initiative.
