Of 101 hip patients, 36 (36%) were referred for surgical assessment (mean OHS: 21, range: 5\u201344). No patients referred for surgical assessment were above previously reported economic thresholds for OKS (43) or OHS (45). Setting thresholds of OKS \u226431 and OHS \u226435 might have resulted in an additional 22 knee referrals and 26 hip referrals in our cohort. Extrapolating hub results across England suggests a possible increase in referrals nationally, of around 13 000 additional knee replacements and 4500 additional hip replacements each year.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Musculoskeletal hubs currently consider OKS\/OHS and other factors when making decisions about referral to secondary care for joint replacement. Those referred typically have low OHS\/OKS, and introducing evidence-based OKS\/OHS thresholds would prevent few inappropriate (high-functioning, low-pain) referrals. However, our findings suggest that some patients not currently referred could benefit from arthroplasty based on OKS\/OHS. More research is required to explore other important patient characteristics currently influencing hub decisions.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjopen-2019-028915","type":"journal-article","created":{"date-parts":[[2020,7,3]],"date-time":"2020-07-03T05:47:25Z","timestamp":1593755245000},"page":"e028915","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Who gets referred for knee or hip replacement?
