Cross-Cultural Validity and Differential Item Functioning of the Orthotics and Prosthetics Users' Survey With Swedish and United States Users of Lower-Limb Prosthesis

Background: Many persons with upper limb amputation reject prostheses, and many are not satisfied with their devices. Research is needed to understand modifiable factors related to device satisfaction. Myoelectric devices with multiple degrees of freedom are now available; however, no studies have examined whether they lead to greater device satisfaction. Prosthetic training contributes to more skillful prosthesis use and greater likelihood of long-term use; however, the relationship between training and device satisfaction is unclear. Objectives: (1) To describe and compare satisfaction by prosthesis and terminal device type and (2) to identify factors associated with satisfaction. Study design: Cross-sectional study. Methods: Participants were 449 persons with unilateral upper limb amputation who used a prosthesis. Participants described their prostheses, prosthetic training, device repairs, visits to a prosthetist, and rated device satisfaction using two standardized measures (Trinity Amputation and Prosthesis Experience Scales Satisfaction scale and Orthotics and Prosthetics Users’ Survey - Client Satisfaction with Devices scale). Multivariate generalized linear regression models examined the relationship between prosthesis and terminal device type and satisfaction, controlling for covariates that were meaningful in bivariate analyses. Results: There were no differences in satisfaction by prosthesis type or terminal device degrees of freedom. Satisfaction was associated with receipt of training to use the initial prosthesis, amputation level, age, and race. Conclusion: No differences in satisfaction by device or terminal device type were observed. Worse satisfaction was associated with more proximal amputation level, younger age, and black race. The association between receipt of initial prosthetic training and device satisfaction points to the critical role of occupational or physical therapy in the early stages of prosthetic care. Clinical relevance Prosthetic satisfaction did not vary by device or terminal device degrees of freedom. Proximal amputation level, younger age, and black race were associated with lower prosthetic satisfaction. Receipt of initial prosthetic training was associated with greater device satisfaction, pointing to the critical role and lasting impact of early training.

“…Direct waiting times were compared using a two-sided t -test. The CSS was analyzed item by item because its unidimensionality has been questioned, 18 , 21 using a two-sided Mann–Whitney U test. The QPS was analyzed using a two-sided Wilcoxon signed-rank test.…”

Background:Waiting is common in health care, delays intervention, and has negative effects on satisfaction with services.Objectives:To evaluate effects of a modified walk-in system, where patients were invited consecutively from the waiting list to attend the clinic on a walk-in basis, on waiting times, services, and work environment.Study design:Parallel-group trial.Methods:In all, 1286 consecutive patients in need of shoe insoles were randomized to waiting lists for modified walk-in (n = 655) or a scheduled appointment (n = 631). Seven staff members also participated.Results:The median indirect waiting time to first appointment was 40 days shorter for modified walk-in (135 days) than for scheduled appointment (175 days; p < 0.001); 17% of those randomized to modified walk-in did not attend the clinic compared to 6% for scheduled appointment (p < 0.001). Mean direct waiting time in the waiting room was 9.9 min longer for modified walk-in than for scheduled appointment (p < 0.001). Patients attending modified walk-in or a scheduled appointment reported similar levels of satisfaction with services. Staff reported more support from co-workers with modified walk-in than with scheduled appointment (p = 0.041).Conclusion:The modified walk-in can reduce indirect waiting times without any substantial worsening of direct waiting times, service quality, or work environment. Studies are needed to investigate why many patients drop out from modified walk-in.Clinical relevanceA modified walk-in system can cut the queues and create more timely interventions by reducing indirect waiting times. This system can therefore be recommended in secondary-care prosthetic and orthotic clinics to reduce patients’ suffering from their health condition.
