Trends in Hospital-Based Specialty Palliative Care in the United States From 2013 to 2017.

Importance: Although palliative care (PC) historically focused on patients with cancer and those near the end of life, evidence increasingly demonstrates a benefit to patients with a broad range of serious illnesses and to those earlier in their illness. The field of PC has expanded and evolved rapidly, resulting in a need to characterize practice over time to understand whether it reflects evolving evidence and guidelines. Objective: To characterize current practice and trends among patients cared for and outcomes achieved by inpatient specialty PC services in the United States. Design, Setting, and Participants: This retrospective cohort study was performed from January 1, 2013, to December 31, 2017, at 88 US hospitals in which PC teams voluntarily participate in the Palliative Care Quality Network (PCQN), a national quality improvement collaborative. A total of 135 197 patients were referred to PCQN teams during the study period. Initial analyses of the study data were conducted from March 3 to March 21, 2018. Exposure: Inpatient PC consultation. Main Outcomes and Measures: A total of 23 standardized data elements collected by PCQN teams that provided information about the characteristics of referred patients, including age, sex, Palliative Performance Scale score, and primary diagnosis leading to PC consult; reason(s) given for the consultation; and processes of care provided by the PC team, including disciplines involved, number of family meetings held, advance care planning documentation completed, and screened for and intervened on needs. Results: A total of 135 197 patients were referred to inpatient PC (51.0% female; mean age, 71.3 years [range, 57.8-82.5 years]) and were significantly debilitated (mean Palliative Performance Scale score, 34.7%; range, 14.9%-56.8%). Cancer was the most common primary diagnosis (32.0%; range, 11.3%-93.9%), although rates decreased from 2013 to 2017 (odds ratio [OR], 0.84; 95% CI, 0.79-0.91; P < .001). Pain and other symptoms were common and improved significantly during the consultation period (pain: χ2 = 5234.4, P < .001; anxiety: χ2 = 2020.7, P < .001; nausea: χ2 = 1311.8, P < .001; dyspnea: χ2 = 1993.5, P < .001). Most patients were discharged alive (78.7%; range, 44.7%-99.4%), and this number increased over time (OR, 1.36; 95% CI, 1.27-1.46; P < .001). Compared with 2013, rates of discharge referral to clinic-based (OR, 4.00; 95% CI, 2.95-5.43; P < .001) and home-based PC (OR, 2.63; 95% CI, 1.92-3.61; P < .001) also increased significantly by 2017, whereas referrals to hospice decreased (OR, 0.56; 95% CI, 0.51-0.62; P < .001). Conclusions and Relevance: Inpatient PC teams cared for an increasing percentage of patients with diagnoses other than cancer and saw more patients discharged alive, consistent with guidelines recommending specialty PC for all patients with serious illness earlier in their illnesses. Most patients with symptoms improved quickly. Variation in practice and outcomes among PCQN members suggests that there are opportunities for further improvements in care.
