This document provides methods and materials for providing a scoring system to prognose the development of prosthetic joint infection (PJI). For example, a prognostic scoring system as well as methods for making and using a prognostic scoring system for the development of PJI to assist clinicians in implementing intervention or early diagnostic strategies are provided.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for detecting an arthroplasty patient as having a 20% or more chance of developing prosthetic joint infection, wherein said method comprises detecting the presence of 13 or more points for said patient, wherein: (a) two points are assigned to said patient if said patient has a BMI ≧40 or <25; (b) two points are assigned to said patient if said patient has had prior other surgery; (c) two points are assigned to said patient if said patient has had prior arthroplasty; (d) two points are assigned to said patient if said patient is immunosuppressed; (e) two points are assigned to said patient if said patient has an ASA score of 3; (f) six points are assigned to said patient if said patient has an ASA score of 4; (g) one point is assigned to said patient if said patient had a procedure time of less than two hours; and (h) three points are assigned to said patient if said patient had a procedure time of more than four hours. 2. A method for detecting an arthroplasty patient with a score of 13 or higher who has a 20% chance of developing prosthetic joint infection, wherein said method comprises: (a) assigning a score of two points if said patient has a BMI ≧40 or <25; (b) assigning a score of two points if said patient has had prior other surgery; (c) assigning a score of two points if said patient has had prior arthroplasty; (d) assigning a score of two points if said patient is immunosuppressed; (e) assigning a score of two points if said patient has an ASA score of 3; (f) assigning a score of six points if said patient has an ASA score of 4; (g) assigning a score of one point if said patient had a procedure time of less than two hours; and (h) assigning a score of three points if said patient had a procedure time of more than four hours. 3. A method for detecting an arthroplasty patient having at least a 17% chance of developing prosthetic joint infection, wherein said method comprises detecting, at least two weeks post procedure, the presence of 7 or more points for said patient, wherein: (a) one point is assigned to said patient if said patient has a BMI ≧40 or <25; (b) one point is assigned to said patient if said patient has had prior other surgery; (c) one point is assigned to said patient if said patient has had prior arthroplasty; (d) one point is assigned to said patient if said patient is immunosuppressed; (e) one point is assigned to said patient if said patient has an ASA score of 3; (f) three points are assigned to said patient if said patient has an ASA score of 4; (g) one point is assigned to said patient if said patient had a procedure time of less than two hours; (h) two points are assigned to said patient if said patient had a procedure time of more than four hours; and (i) three points are assigned to said patient if said patient had wound drainage within one month of arthroplasty. 4. A method for detecting an arthroplasty patient at one month post procedure with a score of 7 or higher who has a 17% chance of developing prosthetic joint infection, wherein said method comprises: (a) assigning a score of one point if said patient has a BMI ≧40 or <25; (b) assigning a score of one point if said patient has had prior other surgery; (c) assigning a score of one point if said patient has had prior arthroplasty; (d) assigning a score of one point if said patient is immunosuppressed; (e) assigning a score of one point if said patient has an ASA score of 3; (f) assigning a score of three points if said patient has an ASA score of 4; (g) assigning a score of one point if said patient had a procedure time of less than two hours; (h) assigning a score of two points if said patient had a procedure time of more than four hours; and (i) assigning a score of three points if said patient had wound drainage within one month of arthroplasty.
