This study elucidated the prevalence and burden of SSI in German hospitals based on reimbursement data. The significantly increased mortality and underfunding of patients with SSI calls for efforts to prevent SSI using evidence-based care bundles.
Background Surgical site infections (SSI) present a substantial burden to patients and healthcare systems. This study aimed to elucidate the prevalence of SSIs in German hospitals and to quantify their clinical and economic burden based on German hospital reimbursement data (G-DRG). Methods This retrospective, cross-sectional study used a 2010-2016 G-DRG dataset to determine the prevalence of SSIs in hospital, using ICD-10-GM codes, after surgical procedures. The captured economic and clinical outcomes were used to quantify and compare resource use, reimbursement and clinical parameters for patients who had or did not have an SSI. Findings Of the 4,830,083 patients from 79 hospitals, 221,113 were eligible. The overall SSI prevalence for the study period was 4.9%. After propensity-score matching, procedure type, immunosuppression and BMI >= 30 were found to significantly affect the risk of SSI (p<0.001). Mortality and length of stay (LOS) were significantly higher in patients who had an SSI (mortality: 9.3% compared with 4.5% [p<0.001]; LOS (median [interquartile range, IQR]): 28 [27] days compared with 12 [8] days [p<0.001]). Case costs were significantly higher for the SSI group (median [IQR]) Euro19,008 [25,162] compared with Euro 9,040 [7,376] [p<0.001]). A median underfunding of SSI was identified at Euro1,534 per patient. Interpretation The dataset offers robust information about the real-world clinical and economic burden of SSI in hospitals in Germany. The significantly increased mortality of patients with SSI, and their underfunding, calls for a maximization of efforts to prevent SSI through the use of evidence-based SSI-reduction care bundles.
