ABSTRACT
BACKGROUND: Athletes demonstrate high levels of physical function, leading to difficulties in patient-reported outcome scoring and interpretation. In particular, the ability of patient-reported outcome (PRO) instruments to adequately discriminate between high levels of upper extremity function-that is, the ceiling effect-is limited. This study evaluated performance characteristics of the shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) survey and Patient-Reported Outcomes Measurement Information System (PROMIS) metrics in a population of Division 1 intercollegiate athletes, with specific attention to ceiling effects. METHODS: At a single institution, Division I intercollegiate athletes cleared for full participation in the 2018-2019 season were eligible. The following PROs were collected prospectively via tablet computer: PROMIS upper extremity (UE) computer adaptive test (CAT), PROMIS physical function (PF) CAT, QuickDASH, and QuickDASH Sports/Performing Arts Module. Descriptive statistics, and ceiling and floor effects, were calculated. The proportion of athletes with maximal scores on each PRO were compared to normative values using the 1-sample Wilcoxon signed rank test. RESULTS: A total of 268 participants were included; the mean age was 19.9 ± 1.5 years, 49% were female, and 61% were overhead athletes. Large ceiling effects were observed for the UE CAT (46%), QuickDASH (58%), and QuickDASH Sports Module (82%). The PF CAT demonstrated a relatively low ceiling effect of 6.7%. Athlete scores were all significantly better than published age-matched values from a normative population for all instruments, with the exception of no difference on the QuickDASH for males. DISCUSSION AND/OR CONCLUSION: The PROMIS UE CAT and QuickDash instruments are limited in their ability to assess and discriminate upper extremity function in highly functioning individuals such as Division I athletes. The PROMIS PF CAT, a measure of general physical function, did not suffer from a large ceiling effect.

PURPOSE: The relationship between biopsychosocial factors and patient-reported function is less clear in pediatric than in adult hand surgery patients. Our primary hypothesis was that pain interference (PI) and peer relationships (PR) would demonstrate association with upper extremity function. Secondarily, we hypothesized that the magnitude of this effect would increase with age. METHODS: Patients aged 5 to 17 years presenting to a tertiary academic clinic between October 2017 and January 2019 were included. The parent/guardian was administered the following instruments after indicating they, rather than the patient, were answering the questions on a tablet computer: Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Parent Proxy (PP) Computer Adaptive Test (CAT) v2.0, PROMIS PI PP CAT v2.0, and the PROMIS PR PP CAT v2.0. Ceiling/floor effects and Spearman correlations were calculated. Multivariable Tobit modeling was performed to determine whether biopsychosocial factors and upper extremity function were associated. Multivariable regression coefficients were compared between age cohorts using a separate multivariable model to evaluate the interaction between age and other predictors. RESULTS: Of 139 included participants, the mean age was 11.7 ± 3.7 years and 50% were female. For patients 11 years of age or younger, UE was weakly correlated with PI (coefficient, -0.34; 95% confidence interval, -0.56 to -0.08) and was not correlated with PR. For patients older than 11 years, UE had moderate correlation with PI (coefficient, -0.60; 95% confidence interval, -0.72 to -0.45) and was not correlated with PR. Multivariable analysis demonstrated a significant negative association between PI and UE, with a significantly larger magnitude of effect for patients older than 11 years of age. CONCLUSIONS: The biopsychosocial model applies to pediatric hand surgery patients. The association between greater pain interference and worse patient-reported upper extremity function, as assessed using parent proxy instruments, was significantly stronger for patients older than 11 years than those 11 years old or younger. CLINICAL RELEVANCE: This study suggests that the biopsychosocial model applies to pediatric hand patients.
