Abstract

fetched live from OpenAlex

OBJECTIVE: Decision boards (DBs) help clinicians present options and include patients in the decision-making process. Our objective was to describe the steps to develop a DB to support shared decision making and assess reliability and construct validity. METHODS: Systemic lupus erythematosus (SLE) scenarios were designed with the support of experts for disease severity, potential side effects, and outcomes. The DB comprised clinical information, 2 different treatment options (oral and intravenous), a description of the potential to control SLE within 5 years, and a list of potential side effects. Patients selected what they thought would be the 3 worst side effects and were informed of the probability that these would occur. We presented the DB to 172 patients who were asked to select and justify 1 treatment option. Reliability was assessed by kappa statistics. Construct validity was tested by an a priori hypothesis, analyzing the correlation between treatment decision and side effects selected, self-assessment score, educational level, and clinical aspects. RESULTS: Patients favored oral medication, and side effects most often listed were iatrogenic cancer (44.2%), hair loss (21.6%), and severe infection (19.1%). Justifications were risk (48.9%), practicality (36.6%), effectiveness (12.2%), and risk-benefit tradeoff (2.3%). Reliability was similar to that found in the test phase (kappa = 0.689, P < 0.001). Validity was tested by prediction of treatment decision based on the undesirable side effects selected (P = 0.047). DB content was clear and easy for all patients to understand (P = 0.05). Immunosuppressive drugs influenced patient decisions (P = 0.006). CONCLUSION: DB is a reliable and valid instrument to assess SLE patient preference.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
