Understanding the factors associated with failure is essential for informed decision-making between patients and clinicians, and for reducing the failure rate. This review aims to identify, describe and appraise the literature examining prognostic factors for failure of TER.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and analysis<\/jats:title><jats:p>This systematic review will be conducted and reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Electronic literature searches will be conducted using Medline, EMBASE, PubMed and Cochrane. The search strategy will be broad, including a combination of subject headings (MESH) and free text search. This search will be supplemented with a screening of reference lists of the included studies and relevant reviews. Two independent reviewers will screen all search results in two stages (title and abstract, and full text) based on the Population, Index prognostic factor, Comparator prognostic factor, Outcome, Time and Setting criteria. The types of evidence included will be randomised trials, non-randomised trials, prospective and retrospective cohort studies, registry studies and case\u2013control studies. If the literature lacks enough studies, then case series with 50 or more TERs will be considered for inclusion. Data extraction and risk of bias assessment for included studies will be performed by two independent reviewers using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies for Prognostic Factors and Quality In Prognostic Studies tools.<\/jats:p><jats:p>Meta-analyses of prognostic estimates for each factor will be undertaken for studies that are deemed to be sufficiently robust and comparable. Several challenges are likely to arise due to heterogeneity between studies, therefore, subgroup and sensitivity analyses will be performed to account for the differences between studies. Heterogeneity will be assessed using Q and I<jats:sup>2<\/jats:sup>statistics. If I<jats:sup>2<\/jats:sup>&gt;40%\u2009then pooled estimates will not be reported. When quantitative synthesis is not possible, a narrative synthesis will be undertaken. The quality of the evidence for each prognostic factor will be assessed using the Grades of Recommendation Assessment, Development and Evaluation tool.<\/jats:p><\/jats:sec><jats:sec><jats:title>PROSPERO registration number<\/jats:title><jats:p>CRD42023384756.<\/jats:p><\/jats:sec>","DOI":"10.1136\/bmjopen-2023-071705","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T16:17:34Z","timestamp":1693412254000},"page":"e071705","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Prognostic factors associated with failure of total elbow replacement: a protocol for a systematic review"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0045-7257","authenticated-orcid":false,"given":"Zaid","family":"Hamoodi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celina K","family":"Gehringer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucy M","family":"Bull","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2266-6615","authenticated-orcid":false,"given":"Tom","family":"Hughes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lianne","family":"Kearsley-Fleet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9000-4413","authenticated-orcid":false,"given":"Jamie C","family":"Sergeant","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam C","family":"Watts","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"2023083009152115000_13.8.e071705.1","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1302\/2058-5241.5.190036","article-title":"Global trends in indications for total elbow arthroplasty: a systematic review of national registries","volume":"5","author":"Macken","year":"2020","journal-title":"EFORT Open Rev"},{"key":"2023083009152115000_13.8.e071705.2","doi-asserted-by":"crossref","first-page":"967","DOI":"10.1302\/0301-620X.102B8.BJJ-2019-1465.R1","article-title":"Total elbow arthroplasty in patients with rheumatoid arthritis","volume":"102-B","author":"Chou","year":"2020","journal-title":"Bone Joint J"},{"key":"2023083009152115000_13.8.e071705.3","doi-asserted-by":"crossref","first-page":"495","DOI":"10.2340\/17453674.2022.2753","article-title":"How long does an elbow replacement last?
