Experiences of Using Patient Decision Aids for Decisions About Cancer Treatment: A Meta-Aggregation of Qualitative Studies.

Background: Inconsistent results have been found regarding the effects of patient decision aids (PtDAs) in supporting patients' decision-making for cancer treatment.

Objective: This qualitative meta-aggregation presents the experiences of using PtDAs, as perceived by adult patients with cancer, and highlights the components they perceived as important.

Methods: We used the 3-phase process for meta-aggregation suggested by Joanna Briggs Institute to identify published studies with qualitative evidence from CINAHL, Ovid-MEDLINE, APA PsycINFO, and EMBASE databases. The selected studies involved adults with various cancer diagnoses. The phenomenon of interest and the context for this review were people's experiences of using PtDAs for decisions about first-line cancer treatment.

Results: A total of 16 studies were included. The authors achieved consensus on 5 synthesized findings about PtDAs: (1) improved understanding of treatment options and patient values and preferences; (2) served as platforms for expressing concerns, obtaining support, and having meaningful conversations with healthcare providers; (3) facilitated active personal and family engagement in decision-making; (4) enabled recall of information and evaluation of satisfaction with decisions; and (5) presented potential structural barriers.

Conclusions: This study used qualitative evidence to demonstrate the usefulness of PtDAs and identify aspects patients with cancer find particularly beneficial.

Implications for practice: Nurses play a crucial role in supporting patients and family caregivers throughout the decision-making process for cancer treatment. Patient decision aids that balance complex treatment information with simple language and illustrations or graphs can enhance patients' comprehension. The integration of values clarification exercises into care can further improve patients' decisional outcomes.
