PROPREDICT Decision Support Tool: Using Evidence to Guide Precision Prosthesis Prescription and Rehabilitation Planning.

The usability testing included only 12 VHA clinicians, so the feedback is from a small group. The study did not test patient outcomes, so it does not show that the tool changes prosthesis prescription, mobility, patient satisfaction, or K-level accuracy. The prediction model was developed and validated in a U.S. Veteran population comprised primarily of men, so its probabilities may not transfer to other populations. Feedback came only from VA clinicians, who may have different workflows and opinions from non-VA clinicians. The model does not include historical mobility or the patient's perceived desire to ambulate. The clinicians were experienced, with a range of 6 to 30 years, and early career providers did not volunteer. The tool has not been prospectively compared with achieved mobility levels or with provider-predicted K-levels at prescription. Published PSSUQ benchmarks may not apply directly because tool functions can differ.

Do not read this as proof that PROPREDICT improves prosthesis prescription or patient mobility. The study tested only how 12 clinicians rated the beta calculator, and it did not report patient outcomes or prospective accuracy.
