ContextDespite the expansion of palliative care (PC) services, the public has little knowledge and holds misperceptions about PC, creating barriers to accessing timely specialty PC.ObjectivesTo systematically review the evidence regarding the efficacy of educational interventions to improve knowledge and attitudes about PC among nonhealthcare workers.MethodsWe searched five databases (PubMed/MEDLINE, Embase, CIANHL, Web of Science, and Scopus) for studies investigating educational interventions about specialty PC in adults who identified as patients, caregivers, or members of the public. We included studies that were available in English and had a comparator group. We excluded studies that only sampled health professionals or children. We used the Mixed Methods Appraisal Tool to assess quality and risk of bias.ResultsOf 12,420 records identified, we screened 5948 abstracts and assessed 526 full texts for eligibility. Twenty-one articles were extracted for analysis, representing 20 unique educational interventions. Common methodologies included quasi-experimental (9, 45%), randomized controlled trial (4, 20%), and nonrandomized trial (2, 10%). Common components of the educational interventions included video presentations (9, 45%), written materials (8, 40%), and lectures (4, 20%). Content included definition (14, 70%) and philosophy (14, 70%) of PC, distinctions between PC and hospice (11, 55%), and eligibility for PC (11, 55%). Fourteen (70%) interventions showed statistically significant positive differences in either knowledge or attitudes about PC.ConclusionsWhile educational interventions can positively impact knowledge and attitudes about PC among nonhealthcare workers, more research is needed to inform the design, delivery, and evaluation of interventions to increase knowledge and attitudes about PC.Copyright © 2023 American Academy of Hospice and Palliative Medicine.
