The findings of this systematic review are clinical ly relevant as it has been shown that infection after shoulder surgery results in poor patient-reported outcomes and pose a significant financial burden .
Purpose Infection is a concern after all orthopedic procedures , including shoulder surgery .
This systematic review of literature aim ed to determine risk factors for infection as well as the availability and effectiveness of measures utilized to prevent infection after elective shoulder surgery .
Risk factors for periprosthetic infection after reverse shoulder arthroplasty.
BACKGROUND Management of periprosthetic infection after  reverse shoulder arthroplasty ( RSA )  remains a challenge . Whereas the infection rate after RSA has improved , more information would be helpful to identify patient risk factors for infection after RSA . The purpose of this study was to evaluate risk factors for infection after RSA . METHODS We identified 301 primary RSAs with a minimum of 1-year follow-up in a prospect ively collected shoulder arthroplasty registry . We performed bivariate and multivariable logistic regression analyses to assess the association between patient demographic and clinical characteristics ( age , sex , smoking , diabetes , rheumatoid arthritis , body mass index , and history of prior failed hemiarthroplasty or total shoulder arthroplasty ) and periprosthetic infection after RSA . RESULTS There were 15 periprosthetic infections after RSA ( 5.0 % ) . Patients with a history of RSA for failed arthroplasty ( odds ratio , 5.75 ; 95 % confidence interval , 2.01 - 16.43 ; P = .001 ) and patients younger than 65 years had an increased risk for development of an infection ( odds ratio , 4.0 ; 95 % confidence interval , 1.21 - 15.35 ; P = .021 ) . History of smoking , diabetes , rheumatoid arthritis , or obesity did not contribute to an increased risk of infection after RSA . CONCLUSIONS This is the first study evaluating risk factors for infection after RSA while controlling for confounding variables with multivariable analysis . The greatest risk factors for infection after RSA were history of a prior failed arthroplasty and age younger than 65 years . Patients with these clinical characteristics should be counseled preoperatively about the increased risk for development of infection after RSA
