The global spread of coronaviruses had a great impact on the economic and social situation of most countries. As the backbone of any society, the health sector made a significant contribution through applying emergency risk management plans in order to control the pandemic. Monitoring the average length of hospital stay (ALOS) was an effective way to release the capacity of the health system during this time. The aim was to evaluate the effect of applying risk assessment/management strategies on ALOS and the impact of this ALOS on COVID-19 infection rates among cancer patients. This is a prospective cohort study. All admitted cancer patients in 6 surgical departments from January to June 2021 were included. A total of 1287 patients were admitted to 6 surgical departments during the selected period. About 46% of them had surgery (n = 578), while 54% did not have surgery (n = 700). Among surgical patients, admission rates were highest in February and head and neck department (24% and 22.1%, respectively), and lowest in April and chest department (12.4% and 8%, respectively). ALOS was significantly different across the 6 months (p value < 0.001) with lower ALOS in (April, May, and June) than in (January–February, and March). No significant difference was found across the 6 surgical departments (p value = 0.423). Twenty-eight patients became COVID-19 positive after admission, 25 of them (89%) were infected from March to June—during the time of the third wave—and a significant decreasing linear trend (p value = 0.009) was found. ALOS had significantly reduced with commitment to infection control (IC) interventions and recommendations. The significant decreasing trend of COVID-19 infection from March to June (unlike the rising curve of the 3rd COVID-19 wave by that time) could be explained by improvement in ALOS.

以平均住院时间为目标作为控制措施，以减少手术癌症患者中的 COVID-19 医院获得性感染

冠状病毒在全球的传播对大多数国家的经济和社会状况产生了巨大影响。作为任何社会的支柱，卫生部门通过应用紧急风险管理计划为控制疫情做出了重大贡献。监测平均住院时间（ALOS）是释放这段时间内卫生系统容量的有效方法。目的是评估应用风险评估/管理策略对 ALOS 的效果以及该 ALOS 对癌症患者中 COVID-19 感染率的影响。这是一项前瞻性队列研究。纳入2021年1月至6月6个外科科室收治的所有癌症患者。选取期间，6个外科科室共收治患者1287例。其中约 46% 接受过手术（n = 578），而 54% 的人没有接受手术（n = 700）。外科患者中，2月和头颈科入院率最高（分别为24%和22.1%），4月和胸科入院率最低（分别为12.4%和8%）。6 个月内的 ALOS 存在显着差异（p 值 < 0.001），其中（4 月、5 月和 6 月）的 ALOS 低于（1 月至 2 月和 3 月）。6 个外科科室之间没有发现显着差异（p 值 = 0.423）。28 名患者入院后呈 COVID-19 阳性，其中 25 名患者 (89%) 在 3 月至 6 月（第三波期间）被感染，并且发现了显着下降的线性趋势（p 值 = 0.009）。随着对感染控制 (IC) 干预措施和建议的承诺，ALOS 显着减少。从 3 月到 6 月，COVID-19 感染的显着下降趋势（与当时第三波 COVID-19 的上升曲线不同）可以用 ALOS 的改善来解释。
