Effects of Personalized Risk Information on Patients Referred for Lung Cancer Screening with Low-Dose CT.


ABSTRACT: Background. Low-dose computed tomography (LDCT) screening for lung cancer is a preference-sensitive intervention that should ideally be individualized according to patients' likelihood of benefit and personal values. Personalized cancer risk information (PCRI) may facilitate this goal, but its effects are unknown. Objective. To evaluate the effects of providing PCRI to patients referred for LDCT screening. Design. Mixed-methods, pre-post study using surveys administered to patients before and after provision of PCRI-calculated by the PLCOm2012 risk prediction model-in shared decision-making consultations, and postvisit qualitative interviews. Setting. Centralized specialty-based LDCT screening program at a tertiary care hospital. Participants. Convenience sample of eligible patients referred for LDCT screening. Measurements. Pre- and postvisit surveys assessed patients' 1) perceived lung cancer risk, 2) uncertainty about their risk, 3) minimum risk threshold for wanting screening, 4) interest in LDCT screening, and 5) interest in smoking cessation. Qualitative interviews explored patients' perceptions of the value of PCRI. Screening uptake was assessed by chart review. Results. Sixty of 70 (86%) patients received PCRI and completed pre-post surveys, and 17 patients (28%) completed qualitative interviews. Perceived lung cancer risk decreased from 52% previsit to 31% postvisit (P < 0.0001). However, patients' minimum risk thresholds for screening decreased, their screening interest increased, and all patients completed screening. Qualitative interviews corroborated these effects, suggesting that patients discount and interpret PCRI according to preexisting beliefs and attitudes. Limitations. The study population was a relatively small, single-institution sample of patients referred for screening. Conclusions. Personalized cancer risk information decreases cancer risk perceptions of patients referred for LDCT screening, but has complex effects on screening-related judgments and decisions. The value of PCRI for patients considering LDCT screening requires further investigation.
