Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to capture patient-reported outcomes (PROs) in an efficient manner. Few studies have assessed this instrument postoperatively. Purpose: To compare the PROMIS Physical Function computer adaptive test (PROMIS PF CAT) and Upper Extremity (PROMIS UE) item bank to other previously validated PRO instruments and to evaluate ceiling and floor effects and construct validity responsiveness in patients who underwent operative interventions for shoulder instability. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 72 patients who underwent operative interventions for shoulder instability completed the American Shoulder and Elbow Surgeons (ASES) assessment form, Marx shoulder activity scale (Marx), 36-Item Short Form Health Survey physical function (SF-36 PF) and general health (SF-36 GH), Western Ontario Shoulder Instability Index (WOSI), PROMIS PF CAT, and PROMIS UE before surgery and then at 6 weeks and 6 months postoperatively. Correlation coefficients were calculated among these tools. The effect size of change was also calculated for each tool at each time point. A total of 91 patients who had also undergone surgery for shoulder instability completed these PRO instruments 2 years postoperatively. The percentage of patients hitting the ceiling and floor effects of each of the PRO instruments was calculated at all time points. Results: The PROMIS PF CAT demonstrated excellent-good correlation with the SF-36 PF at all postoperative time points (0.61 at 6 weeks, 0.68 at 6 months, and 0.64 at 2 years; P < .01 for all). The PROMIS UE showed excellent correlation with the ASES at 6 weeks postoperatively (0.73, P < .01). Both the PROMIS PF CAT and PROMIS UE demonstrated the ability to detect change after surgical interventions with a medium to large effect size. The PROMIS UE demonstrated a ceiling effect at 6 months (68.1%) and 2 years (67.0%) postoperatively. The PROMIS PF CAT demonstrated no ceiling effect at any time point. Conclusion: The PROMIS PF CAT demonstrated good to excellent correlation with other previously validated PRO instruments that assess physical function in patients with shoulder instability postoperatively. The PROMIS UE demonstrated good correlation with other PRO tools but had a significant ceiling effect and is not recommended for this patient population. Both tools demonstrated an ability to detect change after surgical interventions with a good effect size.

Background: Shoulder instability is a relatively common condition occurring in 2% of the population. PROMIS (Patient-Reported Outcome Measurement Information System) was developed by the National Institutes of Health in an effort to advance patient-reported outcome (PRO) instruments by developing question banks for major health domains. Purpose: To compare PROMIS instruments to current PRO instruments in patients who would be undergoing operative intervention for recurrent shoulder instability. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 74 patients with a primary diagnosis of shoulder instability who would be undergoing surgery were asked to fill out the American Shoulder and Elbow Surgeons shoulder assessment form (ASES), Marx shoulder activity scale (Marx), Short Form–36 Health Survey Physical Function subscale (SF-36 PF), Western Ontario Shoulder Instability Index (WOSI), PROMIS physical function computer adaptive test (PF CAT), and PROMIS upper extremity item bank (UE). Correlation between PRO instruments was defined as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), and poor (0.2-0.3). Results: Utilization of the PROMIS UE demonstrated excellent correlation with the SF-36 PF ( r = 0.78, P < .01) and ASES ( r = 0.71, P < .01); there was excellent-good correlation with the EQ-5D ( r = 0.66, P < .01), WOSI ( r = 0.63, P < .01), and PROMIS PF CAT ( r = 0.63, P < .01). Utilization of the PROMIS PF CAT demonstrated excellent correlation with the SF-36 PF ( r = 0.72, P < .01); there was excellent-good correlation with the ASES ( r = 0.67, P < .01) and PROMIS UE ( r = 0.63, P < .01). When utilizing the PROMIS UE, ceiling effects were present in 28.6% of patients aged 18 to 21 years. Patients, on average, answered 4.6 ± 1.8 questions utilizing the PROMIS PF CAT. Conclusion: The PROMIS UE and PROMIS PF CAT demonstrated good to excellent correlation with common shoulder and upper extremity PRO instruments as well as the SF-36 PF in patients with shoulder instability. In patients aged ≤21 years, there were significant ceiling effects utilizing the PROMIS UE. While the PROMIS PF CAT appears appropriate for use in adults of any age, our findings demonstrate that the PROMIS UE has significant ceiling effects in patients with shoulder instability who are ≤21 years old, and we do not recommend use of the PROMIS UE in this population.

Background:Baricitinib (BARI) provided rapid and sustained improvements in patient-reported outcomes (PROs) in randomized, controlled trials (RCTs) in patients (pts) with active rheumatoid arthritis (RA) and inadequate responses (IR) to methotrexate (MTX) (RA-BEAM;NCT01710358)1,2and biologic DMARDs (bDMARD-IR; RA-BEACON;NCT01721044)3,4.Objectives:To determine the number needed to treat (NNT) to report improvements ≥minimum clinically important differences (MCIDs) in multiple PROs at Week (Wk) 12 after treatment with BARI 4-mg in RA-BEAM and BARI 2-mg or BARI 4-mg in RA-BEACON. NNTs ≤10 vs placebo (PBO) are considered clinically meaningful.Methods:Evaluated PROs with respective MCID definitions included Patient Global Assessment of Disease Activity (PtGA, 0-100 mm visual analog scale [VAS], MCID ≥10 mm), pain (0-100 mm VAS, MCID ≥10 mm), physical function (Health Assessment Questionnaire-Disability Index, MCID ≥0.22 points), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F], MCID≥4.0), and health-related quality of life (SF-36 physical component summary [PCS: MCID ≥2.5] and domain scores: physical function [PF], role physical [RP], bodily pain [BP], general health [GH], vitality [VT], social functioning [SF], role emotional [RE], mental health [MH], MCID ≥5.0).5The percentages of pts reporting improvements ≥MCID were determined at Wk 12. NNTs were calculated as 1/difference in response rates between BARI 2-mg or 4-mg and PBO.Results:At Wk 12, percentages of pts reporting clinically meaningful improvements were greater and statistically different from PBO (p<0.01) with BARI 2-mg and 4-mg across most PROs in both RCTs. Most NNTs were ≤10. (Figure)Conclusion:Across different populations, MTX-IR and bDMARD-IR pts with active RA reported clinically meaningful improvements in PROs after BARI treatment. The NNTs in these analyses indicate that <10 pts need to be treated with BARI 2- or 4-mg to report a clinically meaningful benefit.References:[1]Taylor et al. NEJM, 2017;376: 652-62[2]Keystone et al.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) is designed to advance patient-reported outcome (PRO) instruments by utilizing question banks for major health domains. Purpose: To compare the responsiveness and construct validity of the PROMIS physical function computer adaptive test (PF CAT) with current PRO instruments for patients before and up to 2 years after anterior cruciate ligament (ACL) reconstruction. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Initially, 157 patients completed the PROMIS PF CAT, Short Form–36 Health Survey (SF-36 physical function [PF] and general health [GH]), Marx Activity Rating Scale (MARS), Knee injury and Osteoarthritis Outcome Score (KOOS activities of daily living [ADL], sport, and quality of life [QOL]), and EuroQol–5 dimensions questionnaire (EQ-5D) at 6 weeks, 6 months, and 2 years after ACL reconstruction. Correlations between instruments, ceiling and floor effects, effect sizes (Cohen d), and standardized response means to describe responsiveness were evaluated. Subgroup analyses compared participants with and without additional arthroscopic procedures using linear mixed models. Results: At baseline, 6 weeks, and 6 months, the PROMIS PF CAT showed excellent or excellent-good correlations with the SF-36 PF ( r = 0.75-0.80, P < .01), KOOS-ADL ( r = 0.63-0.70, P < .01), and KOOS-sport ( r = 0.32-0.69, P < .01); excellent-good correlation with the EQ-5D ( r = 0.60-0.71, P < .01); and good correlation with the KOOS-QOL ( r = 0.52-0.58, P < .01). As expected, there were poor correlations with the MARS ( r = 0.00-0.24, P < .01) and SF-36 GH ( r = 0.16-0.34, P < .01 ). At 2 years, the PROMIS PF CAT showed good to excellent correlations with all PRO instruments ( r = 0.42-0.72, P < .01), including the MARS ( r = 0.42, P < .01), indicating frequent return to preinjury function. The PROMIS PF CAT had the fewest ceiling or floor effects of all instruments tested, and patients answered, on average, 4 questions. There was no significant difference in baseline physical function scores between subgroups; at follow-up, all groups showed improvements in scores that were not statistically different. Conclusion: The PROMIS PF CAT is a valid tool to assess outcomes after ACL reconstruction up to 2 years after surgery, demonstrating the highest responsiveness to change with the fewest ceiling and floor effects and a low time burden among all instruments tested. The PROMIS PF CAT is a beneficial alternative for assessing physical function in adults before and after ACL reconstruction.

Category: Ankle Introduction/Purpose: Peroneal tendon tears are a common cause of lateral ankle pain. When the tear involves more than 50% of the tendon’s cross-sectional area, the treatment algorithm recommends tenodesis of the torn peroneal tendon to the intact peroneal tendon. Previous assessments in the literature of functional outcomes after peroneal tenodesis have widely used the American Orthopedic Foot and Ankle Score (AOFAS) survey as a measurement tool. However, this score was not designed for patient-reported outcomes and its validity and reliability have been questioned. The Medical Outcomes Shortform-36 (SF-36) and PROMIS are tools that have been extensively studied and validated. We sought to assess patient outcomes after peroneal tenodesis using validated tools: SF-36, PROMIS and AOS Disability scores. Methods: Prospective data was collected on patients undergoing peroneal tenodesis for peroneal tendon tears, and who follow up of at least one year. Patients who underwent concomitant procedures (hindfoot fusion, total ankle arthroplasty) were excluded from the study. Baseline patient-reported outcomes (PRO) scores were obtained preoperatively and compared to scores obtained at one year postoperatively. Results: We identified seventeen patients who underwent peroneal tenodesis for peroneal tendon tears. Average age was 62.1 years. SF-36 Physical Function scores increased from an average of 42.0 preop to 60.0 postop (p = 0.0095). PROMIS scores increased from 40.3 to 42.7 (p = 0.3049). There was no statistically significant improvement in postoperative SF-36 Pain scores (p = 0.3216). AOS Disability Scores dropped from 49.6 preop to 38.2 postop (p = 0.3178). AOS Pain scores decreased from 40.7 to 27.0 (p = 0.1779). Total AOS score decreased from 45.1 to 32.6 (p = 0.2204). Conclusion: The SF-36 Physical Function score, which is a validated outcome measure, showed statistically significant improvement postoperatively. Some of the other PROs for peroneal tenodesis failed to show statistically significant improvements, and this is most likely due to low numbers, rendering the cohort somewhat under-powered. Though the data is preliminary, the non-significant scores trended toward improvement. Despite the preliminary nature of this study, satisfactory outcomes of peroneal tenodesis using validated patient-reported outcome scores are demonstrated for the first time. Further study is underway to enlarge the scope of this investigation.

Objectives: Current Hip Patient Reported Outcome Scores (PROs) are not universally obtained, centers use different forms to try to interpret treatment outcomes, and are limited by floor and ceiling effects. Legacy scores of Modified Harris Hip Score (mHHS), International Hip Outcome Tool (iHOT), and Hip Outcomes Score (HOS) are common place and used in the literature. Patient compliance for legacy PROs have been shown to limit proper data collection. PROMIS measures were developed through NIH funding, vetted against a population norm and PROMIS Computer Adaptive Testing (CAT) has been shown in recent literature to compare well with knee and shoulder legacy scores, and are completed in a quicker amount of time. We hypothesize that in a hip preservation population, the CAT PROMIS Profile V2.0 and PROMIS physical function (PF) would show high correlation with legacy scores of (mHHS, iHOT, and HOS). Methods: After obtaining IRB approval, power analysis revealed 86 patients were needed to detect a significant difference. 100 patients were prospectively enrolled. Patients were asked to complete the iHOT-12, mHHS, HOS and then complete the CAT PROMIS Profile v 2.0. Inclusion criteria for the current study included all Initial encounter and single follow-up patients that have completed the CAT portion and started the legacy scores before opting out. Exclusion criteria will be any patient with a repeat encounter, patients under the age of 18 or a patient that did not complete the legacy or CAT scores. Repeat encounters were excluded due to statistical analysis assuming independence among observers. Correlation between instruments was defined as excellent (>0.7), excellent-good (0.7-0.61), good (0.6-0.4), and poor (0.3-0.2). Results: Demographics of 75 females and 25 males, mean BMI 26.3, and mean age 36.1 (range 18-67). The PROMIS Physical function, Pain Intensity, and Ability to Participate in Social Roles showed excellent correlation with the iHOT-12 (r=0.71 P<0.001), mHHS (r=0.8 P<0.001) and HOS (r=0.82 P<0.001). Patients averaged 21.6 questions to complete all seven arms of the PROMIS Profile. No patient experienced a ceiling effect utilizing the PROMIS Profile CAT. Conclusion: The PROMIS Profile allows for an in-depth look at patients’ dysfunction, not asked in current legacy scores. The PROMIS Physical function and Pain Intensity show excellent correlation with iHOT-12, mHHS and HOS. The CAT PROMIS Profile, shows no observed ceiling effect and can be considered to replace current legacy measures in hip preservation.

Objective.To assess the influence of fostamatinib on patient-reported outcomes (PRO) in patients with active rheumatoid arthritis and an inadequate response to methotrexate (MTX).Methods.Patients taking background MTX (N = 457) were enrolled in a phase II clinical trial (NCT00665925) and randomized equally to placebo, fostamatinib 100 mg twice daily (bid), or fostamatinib 150 mg once daily (qd) for 24 weeks. Self-administered PRO measures included pain, patient's global assessment (PtGA) of disease activity, physical function, health-related quality of life (HRQOL), and fatigue. Mean change from baseline and a responder analysis of the proportion of patients achieving a minimal clinically important difference were determined.Results.At Week 24, there were statistically significant improvements in pain, PtGA, physical function, fatigue, and the physical component summary of the Medical Outcomes Study Short Form-36 (SF-36) for fostamatinib 100 mg bid compared with placebo. Mean (standard error) changes from baseline in the fostamatinib 100 mg bid group versus the placebo group were −31.3 (2.45) versus −17.8 (2.45), p < 0.001 for pain; −29.1 (2.26) versus −16.7 (2.42), p < 0.001 for PtGA; −0.647 (0.064) versus −0.343 (0.062), p < 0.001 for physical function; 7.40 (1.00) versus 4.50 (0.94), p < 0.05 for fatigue; 8.52 (0.77) versus 4.90 (0.78), p < 0.01 for SF-36 physical component score; and 3.99 (0.93) versus 3.71 (0.99), p = 0.83 for SF-36 mental component score. Patients receiving fostamatinib 150 mg qd showed improvements in some PRO, including physical function.Conclusion.Patients treated with fostamatinib 100 mg bid showed significant improvements in HRQOL outcomes.

Background: Intra-articular glenohumeral joint changes frequently occur after shoulder instability events. Purpose: (1) To compare demographic characteristics, baseline patient-reported outcomes, and intraoperative findings for patients undergoing primary or revision shoulder stabilization surgery and (2) to determine the incidence of glenohumeral bone and cartilage lesions in this population while identifying factors independently associated with these lesions. Study Design: Cross-sectional study; Level of evidence, 3. Methods: The Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Group shoulder instability database was used to identify all prospectively enrolled patients undergoing shoulder stabilization surgery for anterior instability between October 2012 and September 2016. Any patient who underwent surgery for posterior or multidirectional shoulder instability or concomitant rotator cuff repair surgery was excluded. Patient demographic characteristics, preoperative patient-reported outcomes, and intraoperative findings, including glenohumeral bone and cartilage lesions, were compared for patients undergoing primary and revision shoulder stabilization surgery. Additionally, patients with and without glenohumeral bone and cartilage lesions were compared and independent associations determined using multivariate analysis. Results: There were 545 patients available for analysis (461/545 [84.6%] primary; 84/545 [15.4%] revision). Patients undergoing revision surgery were older ( P = .001), were more frequently smokers ( P = .022), had a greater number of instability events before surgery ( P = .047), more frequently required reduction assistance ( P < .001), and had lower Short Form–36 (SF-36) Mental Component Summary ( P = .020) and Western Ontario Shoulder Instability Index (WOSI) ( P = .026) scores preoperatively. Additionally, patients undergoing revision surgery had a higher frequency of bone and cartilage lesions than those undergoing primary surgery (47.6% vs 18.4%, respectively; P < .001). Male sex, revision surgery, black race, increasing body mass index, increasing patient age, and lower preoperative SF-36 Physical Component Summary score were independently associated with the presence of glenohumeral bone and cartilage lesions at the time of shoulder stabilization surgery. Revision surgery was strongly associated with the presence of glenohumeral bone and cartilage lesions (odds ratio [OR], 4.381 [95% CI, 2.591-7.406]) and glenoid bone loss greater than 10% (OR, 9.643 [95% CI, 5.128-18.134]) or 20% (OR, 13.076 [95% CI, 5.113-33.438]) of the glenoid width. Conclusion: Glenohumeral bone and cartilage lesions are common at the time of shoulder stabilization surgery, occurring more frequently in patients undergoing revision surgery as compared with primary surgery. On the basis of these findings, future prospective studies should aim to compare the clinical outcomes in these 2 groups.

AbstractThe purpose of this study was to establish preoperative validity of the Patient-Reported Outcomes Measurement Information System physical function computer adaptive test (PROMIS PF-CT) with legacy patient-reported outcome measures (PROMs) for meniscal root tears (MRTs). Our study included 51 patients (52 knees) with MRT. Patients completed PROMIS PF-CT, Short Form 36 (SF-36 physical function, pain, general health, vitality, social function, emotional well-being, role limitations due to physical health, and role limitations due to emotional problems), Knee Injury and Osteoarthritis Outcome Score (KOOS pain, symptoms, activities of daily living [ADLs], sports, and quality of life [QOL]), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC pain, stiffness, and function), EuroQol-5 dimensions (EQ-5D), and Knee Activity Scale questionnaires at their preoperative visit. Correlations between the PROMs listed above were evaluated along with floor and ceiling effects. Correlations were defined as weak (0.2–0.39), moderate (0.4–0.59), strong (0.6–0.79), and very strong (0.8–1.0). Preoperative data showed that PROMIS PF-CT has a strong correlation with SF-36 PF, KOOS-ADL, WOMAC-function, and EQ-5D; and moderate correlation with KOOS-sport, KOOS-pain, KOOS-symptoms, KOOS-QOL, WOMAC-pain, and WOMAC-stiffness. The Knee Activity Scale did not show any significant correlation with PROMIS PF-CT (r = 0.12, p = 0.2080). Of all the PROMs administered, PROMIS PF-CT demonstrated no floor or ceiling effects compared with 11.54% ceiling effect in KOOS-sports, and 5.77% floor effect in KOOS-ADL. On average, patients answered fewer PROMIS PF-CT questions (4.15 ± 0.72). PROMIS PF-CT is a valuable tool to assess preoperative patient-reported physical function in patients that may undergo MRT repair. It correlates strongly with other well-established PROMs. It also demonstrated no floor or ceiling effects and demonstrated a low test burden in our sample of 52 knees. This is a level III, prognostic retrospective comparative study.

AbstractThe objectives of this study are to assess perioperative opioid use in patients undergoing knee surgery and to examine the relationship between preoperative opioid use and 2-year postoperative patient-reported outcomes (PROs). We hypothesized that preoperative opioid use and, more specifically, higher quantities of preoperative opioid use would be associated with worse PROs in knee surgery patients. We studied 192 patients undergoing knee surgery at a single urban institution. Patients completed multiple PRO measures preoperatively and 2-year postoperatively, including six patient-reported outcomes measurement information system (PROMIS) domains; the International Knee Documentation Committee (IKDC) questionnaire, numeric pain scale (NPS) scores for the operative knee and the rest of the body, Marx's knee activity rating scale, Tegner's activity scale, International Physical Activity Questionnaire, as well as measures of met expectations, overall improvement, and overall satisfaction. Total morphine equivalents (TMEs) were calculated from a regional prescription monitoring program. Eighty patients (41.7%) filled an opioid prescription preoperatively, and refill TMEs were significantly higher in this subpopulation. Opioid use was associated with unemployment, government insurance, smoking, depression, history of prior surgery, higher body mass index, greater comorbidities, and lower treatment expectations. Preoperative opioid use was associated with significantly worse 2-year scores on most PROs, including PROMIS physical function, pain interference, fatigue, social satisfaction, IKDC, NPS for the knee and rest of the body, and Marx's and Tegner's scales. There was a significant dose-dependent association between greater preoperative TMEs and worse scores for PROMIS physical function, pain interference, fatigue, social satisfaction, NPS body, and Marx's and Tegner's scales. Multivariable analysis confirmed that any preoperative opioid use, but not quantity of TMEs, was an independent predictor of worse 2-year scores for function, activity, and knee pain. Preoperative opioid use and TMEs were neither independent predictors of met expectations, satisfaction, patient-perceived improvement, nor improvement on any PROs. Our findings demonstrate that preoperative opioid use is associated with clinically relevant worse patient-reported knee function and pain after knee surgery.
