Surgeons often use the Patient Acceptable Symptom State to evaluate surgical success. Additionally, a recent study established specific PASS thresholds for PROMIS scores in patients undergoing hallux valgus correction. Specifically, these values help determine if a patient feels truly satisfied with their outcome. Furthermore, the research team analyzed 286 patients retrospectively to find these benchmarks. Consequently, they used two-year postoperative data and patient-reported satisfaction scales. Moreover, they utilized two validated anchor questions. Thus, the study provides a clear framework for measuring orthopedic outcomes.

Clinical Application of PASS Thresholds for PROMIS

Interestingly, the results showed that over 71% of patients reached the target state for physical function and pain. Specifically, the physical function threshold was 50.3. Similarly, the pain intensity threshold was 41.5. However, certain factors changed these odds for individual patients. For example, a lower body mass index significantly improved the success rates. Conversely, patients undergoing first metatarsophalangeal fusion faced a lower likelihood of meeting physical function goals. Therefore, surgeons can now counsel patients more accurately using these data points. Finally, these scores improve overall treatment planning and patient education.

Frequently Asked Questions

What is the PASS threshold for physical function?

The study established a PASS threshold of 50.3 for the PROMIS Physical Function domain following hallux valgus correction surgery.

Which factors predict better surgical outcomes?

Patients with a lower body mass index and higher preoperative PROMIS scores are more likely to meet the PASS thresholds after surgery.
