Which patient factors influence pre-operative and post-operative completion of patient reported outcome surveys in total joint replacement surgery?

Background: Patient reported outcome measures have become a widely-used indicator of the quality of interventions in joint reconstruction. This study aimed to determine which patient variables affect completion of patient-reported outcome measurements. Methods: All patients undergoing total knee or total hip arthroplasty (TKA/THA) between January 1st Results: In the adjusted multivariable analysis, patients older than 60 years had higher preoperative PROMs compliance. TKA (OR 0.92 95 % CI [0.86, 0.98]) and an ASA score of 3 or 4 (OR 0.88 95 % CI [0.82, 0.95]) were associated with decreased compliance. Patients aged 60-74 years had higher PROMs compliance than those <60 years (3-months: OR 1.61, 95 % CI [1.40, 1.84]; 6-months: OR 1.70, 95 % CI [1.48, 1.96]; 1-year: OR 1.69, 95 % CI [1.51, 1.90]; 2-year: OR 1.70, 95 % CI [1.52, 1.90]). Additional factors were identified to be correlated with compliance rates at various follow-up time points. Age >60, sex, Length of stay, BMI, ASA score, and TKA vs. THA arthroplasty all influenced PROMs compliance. Conclusions: As PROMs are increasingly used a quality measurement, identification of variables that influence survey completion will help to address selection biases in these measurements.
