Objective: Higher uncertainty is associated with poorer quality of life and may be impacted by clinician communication about the future. We determined how patients undergoing lung transplant evaluation experience uncertainty and communication about the future from clinicians.Methods: We performed a convergent parallel mixed‐methods study using a cross‐sectional survey and semistructured interviews. Patients undergoing lung transplant evaluation at the University of Colorado and the University of Washington answered questions about future communication and completed the Mishel Uncertainty in Illness Scale‐Adult (MUIS‐A; range 33–165, higher scores indicate more uncertainty). Interviews were analyzed using content analysis. Integration of survey and interview results occurred during data interpretation.Results: A total of 101 patients completed the survey (response rate: 47%). Twelve survey participants completed interviews. In the survey, most patients identified changing family roles as important (76%), which was infrequently discussed with clinicians (31%). Most patients (86%) worried about the quality of their life in the future, and 74% said that not knowing what to expect in the future prevented them from making plans. The mean MUIS‐A score was 85.5 (standard deviation 15.3). Interviews revealed three themes: (1) uncertainty of the future distresses participants; (2) participants want practical information from clinicians; and (3) communication preferences vary among participants.Conclusion: Participants experienced distressing uncertainty and wanted information about the future. Communication topics that were important to participants were not always addressed by physicians. Clinicians should address how chronic lung disease and lung transplant can directly impact patients’ lives and support patients to cope with uncertainty.

Rationale: Lung transplantation can extend the lives of individuals with advanced cystic fibrosis (CF). Until March 2023, the Lung Allocation Score (LAS) was used in the United States to determine transplant priority. Certain clinical events or attributes (“risk events”) that are not included in the LAS (e.g., massive hemoptysis) are relatively common and prognostically important in CF and may prompt an exception request to increase priority for donor lungs. The new Lung Composite Allocation Score (CAS) also allows for exceptions based on the same principles. Objectives: To evaluate the frequency of LAS exceptions in persons with CF (PwCFs) listed for lung transplantation and assess whether LAS exceptions are associated with improved waitlist outcomes for PwCFs compared with similarly “at-risk” individuals without LAS exceptions. Methods: A merged dataset combining data from the CF Foundation Patient Registry and the Organ Procurement and Transplantation Network (2005–2019) was used to identify PwCFs listed for lung transplantation. We compared waitlist outcomes between PwCFs with a LAS exception versus those without an exception despite having a risk event. Risk events were defined as an episode of massive hemoptysis, pneumothorax, at least three moderate/severe pulmonary exacerbations, and/or a decrease in forced expiratory volume in 1 second by ⩾30% predicted (absolute) in the prior 12 months. Analyses were performed using competing risk regression with time to transplantation as the primary outcome and death without a transplant as a competing risk. Results: Of 3,538 listings from 3,309 candidates, 2% of listings (n = 81) had at least one exception. Candidates with an exception and those with a risk event but no exception received lung transplants more slowly than people without an exception or risk event (subdistribution hazard ratio [95% confidence interval]: LAS exception cohort, 0.66 [0.52–0.85]; risk event cohort without exceptions, 0.79 [0.72–0.86]). There was no difference between those with LAS exceptions and those at risk without LAS exceptions: subdistribution hazard ratio, 0.84 (0.66–1.08). Conclusions: LAS exceptions are rare in PwCFs listed for lung transplantation. LAS exceptions resulted in a similar time to transplantation for PwCFs compared with similarly at-risk individuals. As we enter the CAS era, these LAS-based results are pertinent to improve risk stratification among PwCFs being considered for lung transplantation.
