An Algorithm Integrating a Short Form of the Functional Autonomy Measurement System to Predict Discharge Destination After Acute Care Post-Stroke
Bibliographic record
Abstract
Purpose: This study develops a short form of the Functional Autonomy Measurement System (SMAF), the SF-SMAF, for measuring functional capacity in patients undergoing acute care post-stroke, identifies predictors of the discharge destination chosen by the care team, and derives an algorithm that integrates the SF-SMAF and other predictors to guide discharge planning. Method: This multisite prospective cohort study involved 200 patients assessed with the SMAF within 8 days post-stroke. Sociodemographic and clinical data were extracted from patients’ medical records. We performed linear regressions to identify subsets of SMAF items that closely approximate the SMAF total score and asked a panel of experts to make the final selection. We used logistic regression to develop an algorithm that predicts discharge destinations using the SF-SMAF and other predictors. Results: The SF-SMAF includes four items: “washing,” “walking inside,” “judgment,” and “budgeting.” It is highly correlated with the SMAF ( R 2 = 0.94) and, alone, predicts 71% of discharge destinations. Adding obstacles to returning home, support required from caregivers, and the ability to communicate raises the prediction of the proposed algorithm to 82%. Conclusions: The SF-SMAF results closely approximate those of the SMAF in the first week post-stroke. Following further validation, the proposed algorithm could guide clinicians in using the SF-SMAF for discharge planning.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
