BACKGROUND: Widespread implementation of palliative care treatment plans could reduce suffering in the last days of life by adopting best practices of traditionally home-based hospice care in inpatient settings. OBJECTIVE: To evaluate the effectiveness of a multimodal intervention strategy to improve processes of end-of-life care in inpatient settings. DESIGN: Implementation trial with an intervention staggered across hospitals using a multiple-baseline, stepped wedge design. PARTICIPANTS: Six Veterans Affairs Medical Centers (VAMCs). INTERVENTION: Staff training was targeted to all hospital providers and focused on identifying actively dying patients and implementing best practices from home-based hospice care, supported with an electronic order set and paper-based educational tools. MAIN MEASURES: Several processes of care were identified as quality endpoints for end-of-life care (last 7 days) and abstracted from electronic medical records of veterans who died before or after intervention (n= 6,066). Primary endpoints were proportion with an order for opioid pain medication at time of death, donot-resuscitate order, location of death, nasogastric tube, intravenous line infusing, and physical restraints. Secondary endpoints were administration of opioids, order/administration of antipsychotics, benzodiazepines, and scopolamine (for death rattle); sublingual administration; advance directives; palliative care consultations; and pastoral care services. Generalized estimating equations were conducted adjusting for longitudinal trends. KEY RESULTS: Significant intervention effects were observed for orders for opioid pain medication (OR:
