Will the COVID-19 pandemic transform infection prevention and control in surgery? Seeking leverage points for organizational learning.

BACKGROUND: In response to the coronavirus disease of 2019 (COVID-19) pandemic, healthcare systems worldwide have stepped up their infection prevention and control efforts in order to reduce the spread of the infection. Behaviours, such as hand hygiene, screening and cohorting of patients, and the appropriate use of antibiotics have long been recommended in surgery, but their implementation has often been patchy. METHODS: The current crisis presents an opportunity to learn about how to improve infection prevention and control and surveillance (IPCS) behaviours. The improvements made were mainly informal, quick and stemming from the frontline rather than originating from formal organizational structures. The adaptations made and the expertise acquired have the potential for triggering deeper learning and to create enduring improvements in the routine identification and management of infections relating to surgery. RESULTS: This paper aims to illustrate how adopting a human factors and ergonomics perspective can provide insights into how clinical work systems have been adapted and reconfigured in order to keep patients and staff safe. CONCLUSION: For achieving sustainable change in IPCS practices in surgery during COVID-19 and beyond we need to enhance organizational learning potentials.

SARS-CoV-2 pandemic: implications in the management of patients with colorectal cancer

The SARS-CoV-2 pandemic has already reached 3,207,248 patients with more than 225,000 deaths all over the world. Colorectal cancer is the third most diagnosed cancer worldwide, and the healthcare system is struggling to manage daily activities for elective cancer surgery. This review integrates clinical, microbiological, architectural and surgical aspects to develop indications on strategies to manage colorectal cancer patients and ensure safety during the pandemic. Telephone or virtual clinics must be encouraged and phone follow-up should be implemented. Indications for surgery must be rigorous, balancing the advantage of early surgical treatment and risks of treatment delay. To decrease the occupancy rate of intensive care unit beds, elective surgical treatment should be delayed until local endemic control, according to stage of disease. Patients with SARS-CoV-2 infection should be treated only after clinical recovery, two consecutive negative oropharyngeal swabs and, if available, a negative stool sample. Before any elective oncologic procedure, a multidisciplinary oncologic team including an anaesthesiologist and an infectious disease specialist must assess every patient to evaluate the risk of infection and its impact on perioperative morbidity, mortality and oncologic prognosis. The hospital should organise to manage all elective oncologic patients in an 'infection-free' area or refer them to a non-SARS-CoV-2 hospital.

Proof of Concept for a Quick and Highly Sensitive On-Site Detection of SARS-CoV-2 by Plasmonic Optical Fibers and Molecularly Imprinted Polymers.

The rapid spread of the Coronavirus Disease 2019 (COVID-19) pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pathogen has generated a huge international public health emergency. Currently the reference diagnostic technique for virus determination is Reverse Transcription Polymerase Chain Reaction (RT-PCR) real time analysis that requires specialized equipment, reagents and facilities and typically 3-4 h to perform. Thus, the realization of simple, low-cost, small-size, rapid and point-of-care diagnostics tests has become a global priority. In response to the current need for quick, highly sensitive and on-site detection of the SARS-CoV-2 virus in several aqueous solutions, a specific molecularly imprinted polymer (MIP) receptor has been designed, realized, and combined with an optical sensor. More specifically, the proof of concept of a SARS-CoV-2 sensor has been demonstrated by exploiting a plasmonic plastic optical fiber sensor coupled with a novel kind of synthetic MIP nano-layer, especially designed for the specific recognition of Subunit 1 of the SARS-CoV-2 Spike protein. First, we have tested the effectiveness of the developed MIP receptor to bind the Subunit 1 of the SARS-CoV-2 spike protein, then the results of preliminary tests on SARS-CoV-2 virions, performed on samples of nasopharyngeal (NP) swabs in universal transport medium (UTM) and physiological solution (0.9% NaCl), were compared with those obtained with RT-PCR. According to these preliminary results, the sensitivity of the proposed optical-chemical sensor proved to be higher than the RT-PCR one. Furthermore, a relatively fast response time (about 10 min) to the virus was obtained without the use of additional reagents.

Surgical management of oncologic patient during and after the COVID-19 outbreak: practical recommendations from the Italian society of Surgical Oncology.

The recent outbreak of COVID-19 in Italy caused a limitation of the resources of the health system, which necessarily led to their rationalization in the critical phase (phase 1) and a reorganization of the system in the following phase (phase 2). The Italian Society of Oncological Surgery-SICO has drafted these practical recommendations, calibrated on the most recent scientific literature and taking into account current health regulations and common sense. Surgical activity during phase 1 and 2 should follow a dynamic model, considering architectural structures, hospital mission, organizational models. Surgical delay should not affect oncological prognosis. However, COVID-19-positive cancer patients should be postponed until the infection is cured. The patients to consider more carefully before delaying surgery are those who have completed neoadjuvant therapy, patients with high biological aggressiveness tumors or without therapeutic alternatives. The multidisciplinary discussions are fundamental for sharing clinical decisions; videoconference meetings are preferable and use of telemedicine for follow-up is recommended. Especially in phase 1, maximum effort must be made to reduce the spread of the pandemic. Prefer intra-corporeal rather than open anastomosis during laparoscopy and mechanical rather than hand-sewn anastomosis in open surgery. Consider PPE for caregivers during stoma management. Minimal invasive surgery is not discouraged, because there is little evidence for augmented risk. Specific procedures have to be followed and use of energy devices has to be limited. Training programs with COVID-19 + patients are not recommended. All staff in OR should be trained with specific courses on specific PPE use. Differentiate recommendations are presented for every district cancer. Surgical oncology during phase 2 should be guaranteed by individual and distinct protocols and pathways between cancer patients and COVID-19 + patients with resources specifically addressed to the two distinct kind of patients to limit diagnostic/therapeutic interferences or slowdowns. These recommendations are based on currently available evidence about management of oncologic patients during COVID-19 pandemic, were endorsed by the SICO Executive Board, and are considered suitable for nationwide diffusion. They will be subject to updates and revisions in case of new and relevant scientific acquisitions.

Surgery in COVID-19 patients: operational directives.

The current COVID-19 pandemic underlines the importance of a mindful utilization of financial and human resources. Preserving resources and manpower is paramount in healthcare. It is important to ensure the ability of surgeons and specialized professionals to function through the pandemic. A conscious effort should be made to minimize infection in this sector. A high mortality rate within this group would be detrimental.This manuscript is the result of a collaboration between the major Italian surgical and anesthesiologic societies: ACOI, SIC, SICUT, SICO, SICG, SIFIPAC, SICE, and SIAARTI. We aim to describe recommended clinical pathways for COVID-19-positive patients requiring acute non-deferrable surgical care. All hospitals should organize dedicated protocols and workforce training as part of the effort to face the current pandemic.
