Delayed-Onset Organ/Space Surgical Site Infection Worsens Prognosis in High-Risk Stage II and III Colorectal Cancer. J Gastrointest Surg 2023; 27:2515-2525.

Abstract
BACKGROUND It is unclear how early- and delayed-onset organ/space surgical site infections (SSIs) affect the long-term prognosis of patients with colorectal cancer, who are potential candidates for adjuvant chemotherapy. This study aimed to investigate the association between the timing of SSI onset and clinical outcome. METHODS This retrospective, multicenter cohort study evaluated patients who were diagnosed with high-risk stage II or III colorectal cancer and underwent elective surgery between 2010 and 2020. Five-year recurrence-free survival (RFS) was the primary endpoint and was compared between early SSI, delayed SSI (divided based on the median date of SSI onset), and non-SSI groups. RESULTS A total of 2,065 patients were included. Organ/space SSI was diagnosed in 91 patients (4.4%), with a median onset of 6 days after surgery. The early-onset SSI group had a higher proportion of patients with Clavien-Dindo grade ≥IIIb SSI than the delayed-onset SSI. Patients who received adjuvant chemotherapy (AC) had earlier organ/space SSI onset than those who did not. The adjusted hazard ratio of 5-year RFS in the delayed-onset SSI was 2.58 (95% confidence interval: 1.43-4.65; p = 0.002): higher than that in the early-onset SSI, with the non-SSI as the reference. CONCLUSIONS Delayed-onset organ/space SSI worsened long-term prognosis compared to early-onset, and this may be due to delayed initiation of AC. Patients who are clinically suspected of having lymph node metastasis might need additional intervention to prevent delays in commencing AC due to the delayed SSI.

Adverse effects of long-term drain placement and the importance of direct aspiration: a retrospective cohort study. J Hosp Infect 2023; 131:156-163. [PMID: 36370963 DOI: 10.1016/j.jhin.2022.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 09/20/2022] [Accepted: 10/31/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Long-term placement of prophylactic drains may result in retrograde infections. AIM To investigate the association between the timing of drain removal and clinical outcomes. METHODS This retrospective, single-centre cohort study evaluated 110 patients who underwent elective gastrointestinal or hepatopancreatobiliary surgery and developed subsequent organ/space surgical site infection (SSI) between 2016 and 2020. The difference between the culture-positive species of prophylactic drains and direct aspiration was evaluated; whether the prophylactic drains functioned effectively at the time of SSI diagnosis; and whether the empirical antibiotics administered before drainage were effective against all the detected bacteria. Finally, clinical outcomes were compared between early (i.e. cases wherein the prophylactic drain had already been removed or replaced at the time of SSI diagnosis) and late (removal after diagnosis) drain removal. FINDINGS The prophylactic drains functioned effectively in only 27 (25%) patients at the time of SSI diagnosis. Due to the results of direct aspiration cultures, 43% of patients required antibiotic escalation. The median time to drain removal or first replacement was seven postoperative days. The early removal group included 43 patients (39%). Compared with early removal, late removal resulted in a higher frequency of vancomycin use (7.0% vs 22.4%; P = 0.037). CONCLUSION Prolonged prophylactic drain placement is associated with complicated infections requiring vancomycin; therefore, the drains should be removed as soon as possible. Additionally, obtaining the cultures of direct aspiration should be actively considered, as escalation of antimicrobial therapy is often performed based on culture results.

Abstract
BACKGROUND The incidence of organ-space surgical site infections (OSIs) across the US has not decreased to the same extent as superficial and deep surgical site infections (SSIs). This study aimed to highlight the consequences and create a predictive model of OSIs using 2019 NSQIP data. MATERIALS AND METHODS The primary data source was the ACS NSQIP 2019 Participant Use Targeted File (PUF). Chi-squared and independent t-tests evaluated the association of OSIs and other postoperative complications. Variables of interest for our predictive model included 10 surgery types, 10 relevant preoperative laboratory values, and 26 other variables including demographics and comorbidities. A stepwise logistic regression model fit with OSIs as the outcome was used to calculate the predicted ROC and c-index. RESULTS A total of 1,076,441 cases submitted from 719 NSQIP-participating sites were included in our analysis, comprised of 16,751 (1.6%) OSIs with a median of 10 days (IQR: 11 days) between surgery and the development of an OSI. Forty-two variables were included in our final multivariable analysis. Esophageal and pancreatic surgeries yielded an approximate 4- and 6-fold higher increase in the odds of OSI, respectively (P < .001). ROC analysis yielded a c-index statistic of 0.846 (Figure 1). Associated consequences of OSIs included hospital readmission (OR = 20.74, 95% CI: 20.094-21.412, p < .001), sepsis (OR = 35.084; 95%CI: 33.75-36.47, p < .001) and higher probabilities of mortality (34% vs. 0.8%, p < .001) and morbidity (16% vs. 5.8%, p < .001). DISCUSSION OSIs have extensive consequences and may be predictable. These types of infections are multifactorial and require quality surveillance distinct from other SSIs.

Abstract
Background Organ/space surgical site infection (SSI) is a significant clinical problem. The postdiagnosis course of organ/space SSIs and the impact of its early diagnosis on clinical outcomes are yet to be clarified. Thus, we aimed to investigate the association between the timing of diagnosis and the clinical outcome of organ/space SSI. Methods This retrospective, single‐center cohort study evaluated patients who underwent elective gastrointestinal or hepatopancreatobiliary surgery between 2016 and 2020. Clinical outcomes were compared between the early group (ie, SSI diagnosed until postoperative day [POD] 4) and normal‐late group (ie, SSI diagnosed after POD 5). The primary outcome was the final C‐reactive protein (CRP) level within 14 d after organ/space SSI diagnosis. Results In total, 110 patients were evaluated. The median time of diagnosis was 7 d postoperatively (interquartile range, 5–9 d postoperatively). Compared with the normal‐late group, the early group included a higher proportion of patients with Clavien–Dindo grade ≥IIIb (8/21 vs 11/89, P = .01), higher final CRP value within 14 d after SSI diagnosis (mean, 4.49 mg/dL vs 2.27 mg/dL, P = .01), longer postoperative length of hospitalization (median, 45.0 d vs 33.0 d; P = .028), and worse 1‐y overall survival rate (74.8% vs 89.3%, P = .08). Conclusion Early diagnosed organ/space SSI are originally severe and may therefore be detected earlier. Importantly, early diagnosed organ/space SSI is likely to be severe and refractory.
