Patient Centered Preference Survey for Identifying a Proceduralist Performing Endobronchial Ultrasound Bronchoscopy (EBUS)

Background: Endobronchial ultrasound bronchoscopy (EBUS) is a minimally invasive procedure using real-time imaging to biopsy malignant and benign lesions within the thoracic cavity. While physicians rely heavily on the degree of training to obtain EBUS procedural proficiency, patients may not consider training to be the primary factor that influences the physician they choose. Traditionally, patients undergoing any medical procedure assume that the treating physician has completed standardized training and is proficient in procedural techniques. Because there is no standardized training for EBUS, patients cannot necessarily rely on the level of training of the physician performing the procedure. This survey-based study examines factors that were most and least important to patients regarding the physician who would be performing their EBUS bronchoscopy.Methods: Using best-worst scaling (BWS), object case methods (case 1; Louviere et al, 2015), a survey was developed with a balanced incomplete block design (BIBD): 11 objects (Figure 1), repeated 5 times across 11 sets with a set size of 5 and co-occurs with the other 10 objects twice. In the survey, titled EBUS Patient Preference Survey, participants were instructed to identify the factors (objects) that were most and least important to them when making arrangements for an EBUS procedure. The data was analyzed by calculating a normalized best-worst (NBW) score for the total sample/aggregate for each object. The data was also analyzed as a percentage distribution on the proportion selected as most versus least important versus never selected (denominator = 930). Analyses were conducted using SPSS (IBM Corp, Version 26.0).
