This document discusses recommendations for managing surgical systems during the COVID-19 pandemic. It recommends immediately postponing all elective surgeries to reduce transmission and conserve resources. Guidelines are provided for continuing essential surgeries, including developing dedicated COVID-19 operating rooms with strict protocols, minimizing healthcare worker exposure, and preparing for potential intensive care needs or transfers. The situation will continue evolving rapidly, requiring surgical strategies to adapt accordingly.
As COVID-19 spreads quickly from Asia to the rest of the world, hospitals are rapidly becoming hot zones for treatment and transmission of this disease in settings with rising community transmission. Health care workers are increasingly contracting this illness, decreasing the human resources available to care for a population in crisis. Surgical care is a foundation of any health system with both elective and emergency procedures contributing to the health of our populations. However, operating theaters are high risk areas for transmission of respiratory infections given the urgency in management, the involvement of multiple staff, and the need for high transmission-risk activities such as airway management. Our systems are generally well-designed to deal with the occasional high-risk cases. The additional strain presented by a high prevalence of disease, limited resources, and staff under pressure, greatly increase the risks of transmission and the burden on our systems of care during this pandemic. It is necessary for us to act immediately so our systems can support essential surgical care while protecting patients and staff and conserving valuable resources. We can benefit from some of the lessons provided from our colleagues around the world to help us stay on top of these issues as we plan our approach to surgery during the pandemic.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

As COVID-19 spreads quickly from Europe and Asia to the rest of the world, hospitals are rapidly becoming hot zones
for treatment and transmission of this disease in settings with rising community transmission. Health care workers
are increasingly contracting this illness, decreasing the human resources available to care for a population in crisis.
Surgical care is a foundation of any health system with both elective and emergency procedures contributing to the
health of our populations. However, operating theaters are high risk areas for transmission of respiratory infections
given the urgency in management, the involvement of multiple staff, and the need for high transmission-risk
activities such as airway management. Our systems are generally well-designed to deal with the occasional high-risk
cases. The additional strain presented by a high prevalence of disease, limited resources, and staff under pressure,
greatly increase the risks of transmission and the burden on our systems of care during this pandemic. It is necessary
for us to act immediately so our systems can support essential surgical care while protecting patients and staff and
conserving valuable resources.
We can benefit from some of the lessons provided from our colleagues around the world to help us stay on top of
these issues as we plan our approach to surgery during the pandemic.
1. Prepare for a rapidly evolving situation.
Any pathways and plans need to be developed with a recognition that the severity of the situation and the
availability of resources may change on a daily basis.
2. Postpone elective operations immediately.
Elective surgeries should ideally be postponed before it seems necessary. Postponing surgeries will reduce
unnecessary patient traffic in the hospital and decrease the introduction and spread of disease between
symptomatic and asymptomatic patients and health care staff.
In addition, reducing surgeries saves resources including hospital beds, personal protective equipment, as well as
preserving the health of surgical staff.

3. Develop a clear plan for providing essential operations during the
pandemic.
This should include a plan to facilitate emergent life and limb saving surgeries as well as urgent surgeries such as
cancer surgeries where long-term outcomes are dependent on timely interventions. The process should allow for
the application of reasonable clinical judgement. For example, the biopsy of a suspicious breast lump is elective
but cannot be postponed.
4. Educate all surgical staff on personal protective equipment and COVID-19
management.
The appropriate use of personal protective equipment protects patients and staff from COVID-19 transmission, and
yet these items are often not used appropriately. N95 masks that have been clearly shown to reduce transmission in
a laboratory setting rarely work as well in practice. This is in large part because of a lack of awareness of appropriate
donning and doffing procedures. All members of the surgical team should be trained in appropriate use of personal
protective equipment. The risk of transmission and resource consumption in educational simulation sessions
means that other forms of education must be undertaken. Our current situation should serve as a reminder of the
importance of training for disasters and pandemics before the need arises.
5. Decrease exposure of health care staff.
For confirmed COVID-19 cases or cases where there is an active influenza-like illness, limiting operating theater staff
to the essential members is key. Trainees, in particular, should not be involved with cases unnecessarily. As COVID-
19 becomes further established in our communities, asymptomatic patients who are carriers will increasingly enter
the health care system for unrelated ailments and pose a risk for transmission. For this reason, reasonable measures
should be taken even in asymptomatic patients such as strict adherence to universal precautions, frequent
handwashing, and elimination of unnecessary staff. Keeping surgical staff out of hospital and self-isolating at home
when they are not needed is a key measure to preserving our human resources.
6. Develop a dedicated COVID-19 operating space.
The development of a dedicated COVID-19 operating theater may help to contain the spread of disease. The
experience from centers such as Singapore as well as centers that have seen high volumes of cases in other parts of
the world including within the United States and Canada provide some guidance on how these systems can be
optimally designed. These include a number of key points:
1. Designate a specific operating theater for all COVID-19 cases. This room should be out of high-traffic areas
and be completely emptied of all non-essential materials. When an anteroom is available, this should be
used as an area for donning and doffing of personal protective equipment and exchange of equipment,
medications and materials for the case. Instructional posters on appropriate procedures should be
prominently displayed. If an anteroom is not available, a taped off area should be clearly marked for these
activities just outside of the OR door.
3. Accepted for Publication in Annals of Surgery

2. No unnecessary items should be brought into the operating theater, this includes personal items such as
pagers or cell phones and pens. Disposable caps and shoe covers should be worn and discarded after each
case. Disposable pens should be provided in the room. Only the materials necessary for the case should be
within the room and all disposables should be discarded at the end of the case.
3. All traffic in and out of the operating theater should be minimized. A runner or support staff should be
dedicated to the Operating theater to provide all materials needed throughout the case with exchanges
performed using a material exchange cart placed immediately outside of the room or in the anteroom.
4. When possible, the patient should be recovered in the operating theater with dedicated staff until they can
be transferred to an isolation room on the ward or in the intensive care unit.
5. The path of the patient to and from the operating theater should be kept clear. This can be done using
either security or a surgical team member travelling in advance of the patient to clear the way.
6. Consideration should be given to surgical approaches that could decrease operating staff exposure and
shorten case duration.
7. Care pathways and protocols for COVID-19 cases should be very clearly developed and be specific to the
needs of each site. This should include the identification of dedicated team members to manage COVID-19
cases each day.
7. The changing landscape of the pandemic may require patient transfers and
repurposing operating theaters to support critical care patients.
The intensive care needs of the COVID-19 patient population will be substantial, and may quickly overwhelm the
systems that provide critical care. Operating theaters are optimally designed to provide support for ventilated
patients and may become precious resources for the ongoing care of patients typically managed in the intensive
care unit. This need may further strain the surgical capacity of health systems.
Hospitals need to be prepared to transfer patients between centers and share resources in order to optimize the
care of regional populations.
The provision of surgery will continue to be an essential aspect of our healthcare system throughout the pandemic.
All surgical systems will need to adapt to a rapidly changing environment. Having a clear surgical strategy during the
COVID-19 pandemic will keep our systems resilient and effective and allow us to provide the very best care to the
populations we serve. Forums for communication such as that established by the American College of Surgeons
(https://acscommunities.facs.org) can be used to share recommendations and best practices .
