3. To explore the fulfilment of patients’ preoperative expectations regarding recovery to normal activities and the process of returning to work afterTHA orTKA as well as barriers and facilitators of return to work.
1. Feasbility of collecting a comprehensive set of PROMs alongside a national joint arthroplasty register
Chapter 2 describes the feasibility of collecting patient-reported outcome measures alongside the Dutch Arthroplasty Register. For this purpose, the longitudinal Leiden Orthopaedics Outcomes of OsteoArthritis Study (LOAS) was set up. It is a multicentre (7 Hospitals), observational study including patients undergoingTHA or TKA,starting in June 2012.A comprehensive set of PROMs including the mandatory PROMs as imposed by the Dutch Orthopaedic Association (NOV; Nederlandse OrthopaedischeVereniging) plus additional outcomes related to paid employment and health care usage was collected preoperatively and at 6, 12, 24 months and every 2 years thereafter.
The proportions of invited patients taking part in the study (participation rates) and the proportions of patients returning the questionnaires (response rates) were recorded.
Between June 2012 and December 2014, 1796 THA and 1636 TKA patients were invited,of whom 1035THA (58%;mean age 68 years (SD 10),62% female) and 970 TKA (59%; mean age 67 years (SD 9.0), 66% female) participated in the study. At 6 months, 35 THA and 38 TKA patients were lost to follow-up.The response rates among those eligible at 1 and 2 years were 87% (866/992) and 84% (812/972) for THA and 84% (771/917) and 83% (756/906) for TKA patients, respectively.
In conclusion, the prospective collection of a comprehensive set of PROMs can successfully be accomplished alongside a traditional arthroplasty register.In particular to increase the participation rates, more efforts concerning the initial recruitment of patients are needed.
