For each respondent, the conjoint software rank ordered the relative importance of the nine biologic attributes on decision-making. In effect, the software created a “preferences report” for each person. The study also examined how often one person’s preferences report matched another’s. Just like with fingerprints and snowflakes, the analysis found that no two IBD patients were exactly alike.39 For example, when looking at the rank-ordering of all nine attributes, 98% of patients had unique reports. These results show that biologic decision-making is highly individualized. They also suggest that providers cannot rely on demographic or clinical variables to neatly categorize patient preferences or attempt to predict which biologic will optimally map with a patient’s personal values.
