A Systematic Review of Decision Aids in Hematologic Malignancies: What Are Currently Available and What Are We Missing?

Background Patient decision aids (PDAs) are tools designed to facilitate decision-making. In this systematic review, we summarized existing studies on the development and evaluation of PDAs for patients with hematologic malignancies. Patients and Methods We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for articles in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov. We included studies, abstracts, and clinical trial protocols available in English involving PDAs for patients age >= 18 diagnosed with a hematologic malignancy and/or their caregivers. Data were summarized using descriptive statistics. Results Of the 5281 titles/abstracts screened, 15 were included: 1 protocol, 7 abstracts, and 7 full-texts. Six were PDA developmental studies, 6 were pilot studies, and 3 were randomized trials. PDA formats included electronic with web content, videos, and/or audio, questionnaires, bedside instruments, and a combination of various formats. Average participant age ranged from 36.0 to 62.4 years. Patients and caregivers identified efficacy, adverse effects, cost, and quality of life as important decision-making factors. PDAs were associated with increased knowledge and patient satisfaction as well as decreased decisional conflict and attitudinal barriers. Research on PDAs for adult patients with hematologic malignancies and their caregivers is limited. Among the studies, PDAs appear to support patients in shared decision-making. Conclusion While current literature examining the use of PDAs for adults with hematologic malignancies is limited, the positive impact of PDAs on shared decision-making and patient outcomes warrants additional research in this field. Patient decision aids (PDAs) are tools designed to facilitate decision-making. This review summarizes existing studies on the development and evaluation of PDAs for patients with hematologic malignancies.
