Shared decision-making in the management of pulmonary nodules: a systematic review of quantitative and qualitative studies

Objective The objective of this systematic review was to explore the evidence regarding shared decision-making (SDM) in the management of pulmonary nodules. Design Systematic review of quantitative and qualitative studies. Data source Studies published in English or Chinese up to April 2022 were extracted from nine databases: PubMed, PsycINFO, EMBASE, Cochrane Library, Web of Science and CINAHL, China National Knowledge Infrastructure, Wanfang Data and SinoMed Data. Eligibility criteria Studies were eligible if patients or healthcare providers are faced with pulmonary nodule management options or the interventions or experiences were focused on the patient–healthcare provider relationship or health education to make, increase or support shared decisions. All types of studies were included, including quantitative and qualitative studies. Grey literature and literature that had not been peer reviewed were excluded. Poster abstracts and non-empirical publications such as editorials, letters, opinion papers and review articles were excluded. Data extraction and synthesis Two reviewers independently screened abstracts and full texts, assessed quality using Joanna Briggs Institute’s critical appraisal tools, and extracted data from included studies. Thematic syntheses were used to identify prominent themes emerging from the data. Results A total of 12 studies met the inclusion criteria, 11 of which were conducted in USA. These included six qualitative studies and six quantitative studies (including both survey and quasi-experimental designs). Three major themes with specific subthemes emerged: (1) Opportunity (uncertainty in the diagnosis and treatment of pulmonary nodules, willingness to participate in decision-making); (2) Ability (patient’s lack of knowledge, physician’s experience); and (3) Different worldview (misconception, distress among patients, preference for diagnosis and treatment). Conclusions Uncertainty in the management of pulmonary nodules is the opportunity to implement SDM. Patients’ lack of knowledge, distress, and misunderstandings between healthcare providers and patients are both the main obstacles and the causes of the application of SDM.
