While there are many different scoring systems available for foot and ankle specialists to use to assess or demonstrate the effectiveness of treatments , the AOFAS , while it is an unvali date d scoring system , is the most commonly used scoring system in this review .
This review presents data about commonly used patient reported outcomes systems in foot and ankle surgery .
The goal of this systematic review is to determine the most commonly used outcome measurement tools used by foot and ankle specialists and determine their limitations , such as whether they are vali date d , have floor/ceiling effects , and so on .
Preoperative PROMIS Scores Predict Postoperative Success in Foot and Ankle Patients
Background : The use of patient-reported outcomes continues to exp and beyond the scope of clinical research to involve st and ard of care assessment s across orthopedic practice s. It is currently unclear how to interpret and apply this information in the daily care of patients in a foot and ankle clinic . We prospect ively examined the relationship between preoperative patient-reported outcomes ( PROMIS Physical Function , Pain Interference and Depression scores ) , determined minimal clinical important differences for these values , and assessed if these preoperative values were predictors of improvement after operative intervention . Methods : Prospect i ve collection of all consecutive patient visits to a multisurgeon tertiary foot and ankle clinic was obtained between February 2015 and April 2016 . This consisted of 16 023 unique visits across 7996 patients , with 3611 new patients . Patients undergoing elective operative intervention were identified by ICD-9 and CPT code .  PROMIS physical function , pain interference , and depression scores were assessed at initial and follow-up visits . Minimum clinical ly important differences ( MCIDs ) were calculated using a distribution-based method . Receiver operating characteristic ( ROC ) curves were calculated to determine whether preoperative PROMIS scores were predictive of achieving MCID . Cutoff values for PROMIS scores that would predict achieving MCID and not achieving MCID with 95 % specificity were determined . Prognostic pre- and posttest probabilities based off these cutoffs were calculated . Patients with a minimum of 7-month follow-up ( mean 9.9 ) who completed all PROMIS domains were included , result ing in 61 patients . Results : ROC curves demonstrated that preoperative physical function scores were predictive of postoperative improvement in physical function ( area under the curve [ AUC ] 0.83 ) . Similarly , preoperative pain interference scores were predictive of postoperative pain improvement ( AUC 0.73 ) and preoperative depression scores were also predictive of postoperative depression improvement ( AUC 0.74 ) . Patients with preoperative physical function T score below 29.7 had an 83 % probability of achieving a clinical ly meaningful improvement in function as defined by MCID . Patients with preoperative physical function T score above 42 had a 94 % probability of failing to achieve MCID . Patients with preoperative pain above 67.2 had a 66 % probability of achieving MCID , whereas patients with preoperative pain below 55 had a 95 % probability of failing to achieve MCID . Patients with preoperative depression below 41.5 had a 90 % probability of failing to achieve MCID . Conclusion : Patient-reported outcomes ( PROMIS ) scores obtained preoperatively predicted improvement in foot and ankle surgery . Threshold levels in physical function , pain interference , and depression can be shared with patients as they decide whether surgery is a good option and helps place a numerical value on patient expectations . Physical function scores below 29.7 were likely to improve with surgery , whereas those patients with scores above 42 were unlikely to make gains in function . Patients with pain scores less than 55 were similarly unlikely to improve , whereas those with scores above 67 had clinical ly significant pain reduction postoperatively . Reported prognostic cutoff values help to provide guidance to both the surgeon and the patient and can aid in shared decision making for treatment . Level of Evidence : Level II , prognostic study
