Abstract
e16010 Background: The choice of urinary diversion (UD) with cystectomy is an opportunity to provide preference-driven care. We adapted a decision dissonance scale to measure concordance of patient goals with choice of ileal conduit (IC) vs. neobladder (NB) UD. Methods: With patient and clinician input, we identified 6 IC- and 4 NB-aligned goals, each rated on an 11-point scale (0 = not at all important to 10 = very important). Kaiser Permanente members rated the importance of these goals in a comprehensive survey mailed 6 months post-op (71% response rate (269/381)). Excluding respondents (n=93) with contraindications to NB and missing data on goals, we examined structural validity with principal axis factor analysis and convergent validity using correlations with other decision-making measures. Results: Items aligned to IC vs. NB factored separately as hypothesized (Table 1). NB patients prioritized (p<.05) NB-aligned goals (M=8.8, SD=1.8) over NB-dissonant goals (M=4.3, SD=2.4). IC patients’ alignment (M=5.4, SD=2.7) and dissonance (M=5.6, SD=2.1) ratings were similar. Dissonance was negatively correlated with informed decision-making (r=-.27) and satisfaction with care (r=-.21), and positively correlated with decision regret (r=.28) (each p<.01), but not correlated with shared decision making or decision style preference. Alignment was not significantly correlated with decision-making measures. Conclusions: Our measure distinguished patient values that could guide shared decision-making about UD choice. Patients who chose a NB had strong preferences for maintaining body integrity and function. [Table: see text]
