title: Is Drain Tip Culture Prognostic of Surgical Site Infection? Results of 1380 Drain Tip Cultures in Total Hip Arthroplasty.
abstract: The purpose of this study was to evaluate a prognostic value of drain tip culture for surgical site infection (SSI) after total hip arthroplasty. A total of 1380 closed suction drain tips cultured after removal in primary total hip arthroplasty were included in this study. Drains were removed in 12-72 hours after surgery. Drain tip cultures were positive in 11 cases (0.8%). SSI was found in 4 cases (0.3%), where the drain tip cultures were all negative. The sensitivity of drain tip culture for infection after surgery was 0%, and the specificity was 99.7%. We concluded that, drain tip culture cannot be prognostic for SSI after total hip arthroplasty. Routine use of drain tip culture is not supported.
