Most initial non-responders to outcome measures 1 year after TJA may be contactable

GRAPEVINE, Texas — Study results presented here showed patients who are non-responders to requests for patient-reported outcome measures 1 year after total joint arthroplasty are reachable with some effort.
Discussing the importance of response rates for patient-reported outcome measures (PROMs) in a presentation at the American Association of Hip and Knee Surgeons Annual Meeting, Lauren A. Ross, a junior registrar at Edinburgh Orthopaedics, said “the International Society of Arthroplasty Registries has defined a response rate of more than 60% as acceptable.”
Ross and colleagues found in their study that satisfaction rates were not inferior among patients who initially did not respond to outreach regarding collection of PROMs compared with patients who did respond to initial outreach efforts.
“Initial non-response was associated with younger age and worse [preoperative] PROMs,” Ross said.
“The majority of patients were contactable by telephone with effort and with the high collection rates, we find satisfaction rate was not inferior among non-responders,” she said.
Ross and colleagues conducted a prospective case-controlled study of 709 patients scheduled to undergo hip arthroplasty and 737 patients scheduled to undergo knee arthroplasty in 2018. All patients completed PROMs questionnaires preoperatively that included the EuroQual-5D and Oxford Hip Score/Oxford Knee Score. Through the postal service, all patients were sent follow-up PROMs questionnaires to complete at 1 year postoperatively.
In an analysis done in October 2020, results showed 151 (21.2%) of patients who underwent THA and 108 (14.6%) of patients who underwent TKA were true non-responders. Following telephone contact to all true non-responders, there were 83 contactable true non-responders in the THA group (55%) and 91 contactable true non-responders in the TKA group (84.3%).
Researchers found the factors of younger age, significantly worse preoperative PROMs and higher BMI were associated with initial non-response, as well as with continued non-response, in both the THA and TKA groups.
Ross said employment status was a factor that affected contact rates in the THA group, but not in the TKA group.
In general, patients aged older than 66.4 years preferred contact by postal mail and patients aged younger than 66.4 years preferred a digital form of contact, she said.
