Improving resource utilisation and outcomes after total knee arthroplasty through technology-enabled patient engagement

Abstract Background A multi-modal, technology-enabled, patient engagement and pathway management solution (PES) for patients undergoing primary total knee arthroplasty (TKA) was evaluated. The primary outcome measure was length of stay (LoS). The secondary outcome measures were clinical and patient-reported outcomes (PROMs). Methods Retrospective analysis of a consecutive series of 1256 TKA patients before (n = 783) and after (n = 473) implementation of the PES. LoS, PROMs, complications, readmissions, and return to theatre were measured. Results were analysed using bivariate and multivariable regression using general linear models, and a sensitivity analysis on LoS was conducted using interrupted time series (ITS) methods. Results Patients in the PES cohort had a significantly shorter mean LoS of two days (mean 4.7 days) versus the Pre-PES patients (mean 6.7 days; p  Conclusions Outcomes following TKA performed in enhanced recovery programs may be improved using technology to more effectively engage patients and streamline their surgical pathway. Integration of such solutions may significantly reduce LoS and improve PROMs without negatively impacting clinical outcomes.
