Brief Education and a Conjoint Valuation Survey May Reduce Decisional Conflict Regarding Lung Cancer Screening.

Background. Recent data and policy decisions have led to the availability of lung cancer screening (LCS) for individuals who are at increased risk of developing lung cancer. In establishing implementation policies, the US Preventive Services Task Force recommended and the Centers for Medicare and Medicaid Services required that individuals who meet eligibility criteria for LCS receive a patient counseling and shared decision-making consultation prior to LCS. Methods. This study evaluated the potential of a values clarification/preference elicitation exercise and brief educational intervention to reduce decisional conflict regarding LCS. Participants (N = 210) completing a larger online survey responded to a measure of decisional conflict prior to and following administration of a conjoint survey and brief educational narrative about LCS. The conjoint survey included 22 choice sets (two of which were holdout cards), incorporating 5 attributes with 17 levels. Results. Results pertaining to changes in decisional conflict showed that participants reported statistically significantly and clinically meaningful reductions in decisional conflict following administration of the brief educational narrative and conjoint survey across the total score (Δ = 29.30; d = 1.09) and all four decisional conflict subscales: Uncertainty (Δ = 27.75; d = 0.73), Informed (Δ = 35.32; d = 1.11), Values Clarity (Δ = 31.82; d = 0.85), and Support (Δ = 18.78; d = 0.66). Discussion. While the study design precludes differentiating the effects of the brief educational narrative and the conjoint survey, data suggest that these tools offer a reasonable approach to clarifying personal beliefs and perspectives regarding LCS participation. Given the complicated nature of LCS decisions and recent policies advocating informed and shared decision-making approaches, conjoint surveys should be evaluated as one of the tools that could help individuals make choices about LCS participation.

Individual decision making about lung cancer screening: A conjoint analysis of perspectives among a high-risk national sample.

OBJECTIVES: Lung cancer screening (LCS) is effective in reducing lung cancer mortality, but there is limited information available regarding preferences among high-risk individuals concerning LCS. In this study, we use a conjoint valuation analysis (CVA) to better understand which LCS attributes most affect LCS preferences. MATERIALS AND METHODS: We implemented a web-based nationally representative survey that included a full-profile CVA exercise. Participants were over the age of 45, had at least a 20 pack-year smoking history, and no history of lung cancer. The CVA instrument included five LCS attributes, and additional survey items collected demographic and psychosocial information. RESULTS: Participants (n = 210) had a mean age of 61 (SD 8.5) years, approximately half were female (51.9%), and were racially/ethnically diverse. Average relative importance of the LCS program attributes was (from high to low): out of pocket costs (27.3 ± 17.7); provider recommendation (24.8 ± 13.4); mortality reduction (17.2 ± 8.9); false-positive rate (15.8 ± 10.4); and ease of access (14.8 ± 7.3). There was large variation among individuals, but few significant associations of propensity to screen with individual demographic characteristics. Average screening propensity across individuals (1-9 scale) was 3.63 ± 1.6, and average rates of individual scenarios ranged from 2.60 ± 2.00 to 5.57 ± 2.13, indicating low inclination for screening. CONCLUSIONS: We found that overall propensity for screening is low in a high-risk population, and that out of pocket costs were of greater importance to potential screeners than mortality reduction or false-positive rates. Thus, individuals considering or eligible for LCS need additional education and support regarding the LCS landscape in order to achieve informed decision making.

Factors affecting late survival after surgical remodeling of left ventricular aneurysms.

OBJECTIVES: Surgical remodeling of the left ventricle has involved various techniques of volume reduction. This study evaluates factors that influence long-term survival results with 3 operative methods. METHODS: From 1979 to 2000, 157 patients (134 men, mean age 61 years) underwent operations for class III or IV congestive heart failure, angina, ventricular tachyarrhythmia, and sudden death after anteroseptal myocardial infarction. The preoperative ejection fraction was 28% +/- 0.9% (mean +/- standard error), and the pulmonary artery occlusive pressure was 15 +/- 0.07 mm Hg. Cardiogenic shock was present in 26 patients (16%), and an intra-aortic balloon pump was used in 48 patients (30%). The type of procedure depended on the extent of endocardial disease and was aimed at maintaining the ellipsoid shape of the left ventricle cavity. In group I patients (n = 65), radical aneurysm resection and linear closure were performed. In group II patients (n = 70), septal dyskinesis was reinforced with a patch (septoplasty). In group III patients (n = 22), ventriculotomy closure was performed with an intracavitary oval patch. RESULTS: Hospital mortality was 16% (25/157) and was similar among the groups. Actuarial survival up to 18 years was better with a preoperative ejection fraction of 26% or greater (P =.004) and a pulmonary artery occlusive pressure of 17 mm Hg or less (P =.05). Survival was worse in patients who had intra-aortic balloon pump support (P =.03). Five-year survival for all patients in group III was higher than for patients in group II (67% vs 47%, P =.04). CONCLUSIONS: Factors that improved long-term survival after left ventricular surgical remodeling were intraventricular patch repair, preoperative ejection fraction of 26% or greater, and pulmonary artery occlusive pressure of 17 mm Hg or less without the need for balloon pump assist.

Pseudocavitating bronchioloalveolar carcinoma followed over a decade.

A 38-year-old woman with bronchioloalveolar carcinoma (BAC) had a slow-growing cavitary nodule for nearly a decade. When she was hospitalized because of pneumonia 9 years earlier, a chest computed tomography scan showed a 1.5-cm cavitary right upper lobe nodule. At 1, 3, and 9 years computed tomography scans showed slow growth of the nodule to 2.4 cm, corresponding to a volume doubling time of 1494 days. Thoracoscopic biopsy and lobectomy were performed. Pathologic analysis revealed a well-differentiated mucinous BAC (T1N0M0). Pseudocavitation in solitary BAC is rare. A longer period of surveillance may be required to rule out malignancy in this setting. Surgical resection remains the mainstay of therapy.
