Abstract

Purpose: To compare the rate of port removal due to infection between patients with a history of port removal (prior-infection group) and those without (no-prior-infection group), and to determine if a history of port removal due to infection is an independent risk factor for port removal due to infection.

Methods: This single-institution retrospective study identified 3,965 ports placed in 3,825 patients from 2013 to 2022, including 80 ports in patients with a history of port removal due to infection. Port infections (port site infection and bloodstream infection) requiring removal were recorded through chart review. Infection rates were compared using Poisson regression. Multivariate proportional subdistribution hazards regression (PSHREG) analysis was conducted to determine whether a history of port removal due to infection is an independent risk factor for port removal due to infection.

Results: Total follow-up period was 1,912,995 catheter-days (median: 488, range: 1-3,405 days). The rate of port removal due to infection in the prior-infection group was significantly higher than that in the non-prior-infection group (0.74 vs. 0.13 per 1,000 catheter-days, P<0.0001). Multivariate PSHREG analysis identified a history of port removal due to infection was an independent risk factor for port removal due to infection (subdistribution hazard ratio, 4.59; 95% CI, 2.89-7.33; P<.0001). These observations were noted in non-oncology patients, but not in oncology patients.

Conclusions: A history of port removal due to infection was associated with a higher risk of another port removal due to infection. This did not appear to be applicable to oncology patients.

因感染而切除胸廓：既往因感染而切除胸廓的患者的风险。

目的：比较有port port摘除史（感染前组）与无port port摘除史（无感染前组）患者因感染port port摘除的发生率，确定port port摘除史是否为port port摘除的独立危险因素。方法：这项单机构回顾性研究确定了2013年至2022年期间3,825例患者的3,965个端口，其中80例患者因感染而有端口移除史。通过图表审查记录需要切除的港口感染（港口部位感染和血流感染）。用泊松回归比较感染率。采用多变量比例亚分布风险回归（PSHREG）分析，以确定因感染而切除端口的历史是否是因感染而切除端口的独立危险因素。结果：总随访时间为1,912,995导管天（中位数：488，范围：1-3,405天）。先前感染组因感染而切除端口的比率显著高于非先前感染组（0.74 vs 0.13 / 1000导管天）。结论：因感染而切除端口的病史与另一次因感染而切除端口的风险较高相关。这似乎并不适用于肿瘤患者。
