Providing routine healthcare to patients with serious health illnesses represents a challenge to healthcare providers amid the SARS-CoV-2 pandemic. Treating cancer patients during this pandemic is even more complex due to their heightened vulnerability, as both cancer and cancer treatment weaken the immune system leading to a higher risk of both infections and severe complications. In addition to the need to protect cancer patients from unnecessary exposure to SARS-CoV-2 infection during their routine care, interruption, and discontinuation of cancer treatment can result in negative consequences on patients' health, in addition to the ghost of rationing healthcare resources in high demand during a global health crisis. This article aims to explore the ethical dilemmas faced by decision-makers and healthcare providers caring for cancer patients during the SARS-CoV-2 pandemic. This includes setting triage criteria for non-infected cancer patients, fairly allocating limited healthcare resources between cancer patients and SARS-CoV-2 patients, prioritizing SARS-CoV-2 treatment or vaccine, once developed, for cancer patients and non-cancer patients, patient-physician communication on matters such as end-of-life and do-not-resuscitate (DNR), and lastly, shifting physicians' priorities from treating their own cancer patients to treating critically ill SARS-CoV-2 infected patients. Ultimately, no straightforward decision can be easily made at such exceptionally difficult times. Applying different ethical principles can result in very different scenarios and consequences. In the end, we will briefly share the experience of the King Hussein Cancer Center (KHCC), the only standalone comprehensive cancer center in the region.
In December 2019, the World Health Organization (WHO) in China was informed of cases of pneumonia of an unknown cause detected in Wuhan City, Hubei Province, now known as the novel coronavirus or SARS-CoV-2 (1). As of 07th August 2020, the virus had made its way to 188 countries causing a pandemic with almost 20 million confirmed cases (2). This rapid spread of the virus around the world spared healthcare providers and healthcare systems very little time, resulting in multiple medical and ethical mysteries, they are still struggling to unravel. Cancer care amidst the pandemic is in itself a mystery; as patients with cancer carry a higher risk of SARS-CoV-2 infection, Intensive Care Unit (ICU) admissions or even death compared with other patients (3). For example, after applying universal microbiologic screening for asymptomatic cancer patients in one hospital in the United Arab Emirates (UAE), 8.24% (7 out of 85) of the tested patients were positive for SARS-CoV-2 (4).
“What a terrible time to have cancer,” read the headline of an article at The Guardian written by Heather Chaney in her weekly column, describing difficulties in the treatment journey in the middle of the SARS-CoV-2 pandemic (5). Cancer patients and their families experience substantial concern and fear of this virus.
Just like cancer and its treatment may decrease the patient's ability to fight the infection, protective measures against the virus and limitation of health resources may also cause a delay in cancer treatment too. Thus, many ethical questions arise including how to sort cancer patients into prioritized and agreed-on categories? Who is to be treated first, patients with urgent medical needs, or those with the best chances of survival? Are there specific guidelines for cancer care during crisis and shortage of supplies? And what specific guidelines are there for healthcare providers treating cancer patients?
Thereupon, some strategies and guidelines were proposed for cancer patients amid the SARS-CoV-2 crisis (6, 7). Triaging patients was of the most concerning challenge as identification of symptomatic patients with a suspicion of infection is crucial for the protection of other patients and healthcare providers. Screening points were allocated to entry sites of some cancer centers for patients, visitors, and even healthcare providers. Limitation of the number of visitors and providers was also recommended, and early-detection screening appointments were deferred. Regarding outpatient clinic visits, many were rescheduled or substituted with telemedicine when possible.
One controversial strategy was the intentional postponing of adjuvant chemotherapy, radiotherapy, stem cell transplant procedures and elective surgeries, which raises a question on how to balance a delay in cancer management against the risk of infection with SARS-CoV-2. This becomes even more baffling in certain aspects of cancer treatment. For example, hematologic malignancies require prompt diagnosis and treatment, whereas, most solid cancers may have longer treatment windows. Is it ethical to delay treatment in older patients and patients with metastatic disease where time is critical and delay may lead to worsening status and loss of the opportunity to treat? Additionally, should these decisions be unilateral, even when patients and physicians do not meet face-to-face?
Some cancer patients, in particular, are at a higher risk of becoming seriously ill if infected with SARS-CoV-2, these include patients receiving immunosuppressive therapy, targeted cancer treatments, recent bone marrow or stem cell transplants, or who are still taking immunosuppressive drugs in addition to patients with hematological malignancies (8). Revisiting the treatment plan for such patients is advisable. Patients and their healthcare providers should discuss whether the risks of beginning or continuing their cancer treatment could outweigh the benefits (8).
Moreover, as the number of SARS-CoV-2 cases is exponentially increasing, hospitals and cancer centers should expect a surge of cases into their wards, depleting its beds, equipment, and resources. Healthcare providers and patients will be faced with difficult choices. Therefore, setting an ethical triage criterion for non-infected cancer patients is of utmost importance.
Table 1. Different triage strategies (9).
Applying different triaging strategies to the same population (i.e., non-infected cancer patients) will give very different results all of which can be considered ethically justifiable. Health status and comorbidities, site and stage of cancer, and type of treatment and prognosis, all have to be weighed against the ethical principle adopted. For example, if a “protect the most vulnerable” strategy was applied, older patients with more aggressive cancer types and late-stage diagnoses whose treatment will only prolong their life expectancy for a limited time will be prioritized, albeit with potential consumption of the limited available medical resources, which may otherwise be directed to treat and save larger numbers of patients with better overall survival and better chances of benefiting from the treatment of their cancer in the long term. On the contrary, in the “save the greatest number of people” strategy, cancer patients with early stages, less aggressive cancer types, less complicated treatment regimens and higher chances of survival will be at the top of the list, which in the long run would result in more lives saved. For example, an old female patient with breast cancer with metastasis and co-morbidities would serve a good example for the third scenario i.e., protecting the most vulnerable. Whereas a young, otherwise healthy breast cancer patient with localized disease who stands a good chance of benefitting from an early treatment would fit into the first scenario; saving the most lives. Patients who have not yet been diagnosed or have been newly diagnosed and have not started treatment will be neglected in the “first come, first serve” strategy regardless of how life-saving the treatment can be to their case.
The United Kingdom's (UK) National Health Services (NHS) has issued its clinical guideline for the management of non-coronavirus patients requiring acute cancer care on 23rd March 2020. The guideline discussed different priority levels for categorizing patients undergoing surgery, patients on systemic anti-cancer treatments and patients on radiation therapy (Table 2) (8). It can be assumed that the NHS guidance has followed the “protect the most vulnerable” strategy for patients undergoing surgery as this would be judged based on the “emergency status” but a “save the greatest number of people” strategy for patients on systematic anti-cancer treatments as this would “result in the most lives saved” and a mix of both strategies for patients on radiation therapy.
Table 2. National Health Services (NHS) clinical guidelines for the management of non-coronavirus cancer patients (8).
The American Society of Clinical Oncology (ASCO) has created a series of Frequently Asked Questions (FAQs) to guide oncologists in their clinical practice during the SARS-CoV-2 pandemic (7). Other organizations have released guidance for specific cancer types, such as the American Society of Breast Surgeons (10, 11), the American Society of Hematology (12), and the Society of Surgical Oncology (13). Similarly, the European Society for Medical Oncology (ESMO) issued several guidelines on the management of various types of cancers, including for example, breast (14), lung (15), colorectal (16), and pancreatic carcinoma (17). Prioritizing cancer patients is based on a tiered framework that incorporated both the information on the value-based prioritization and clinical cogency of the interventions into a high, intermediate and low priority that would guide the surgical, medical, radiation interventions based on consensus recommendations from international experts.
Other parts of the world have made some efforts to develop recommendations to guide oncologists in providing cancer care during the SARS-CoV-2 in developing countries. Examples include collaborative work initiated through international collaboration, including contributions from some Arab Countries (18).
Allocation of Limited Resources
The current pandemic has stretched healthcare resources in many ways. However, ventilators have stolen much of the show (19). If a SARS-CoV-2 infected cancer patient is competing with another SARS-CoV-2 infected, otherwise healthy, individual for a ventilator, how can one determine who gets the ventilator? A more complex situation can emerge for non-infected cancer patients who need the ventilator for their standard cancer care or terminally ill cancer patients who are already on ventilators; would such groups rank at the bottom of the list? In settings of scarcity such as these, it is important to consider not only what is ethically justifiable but also what is ethically unacceptable. Some may argue that removing terminally ill cancer patients already on ventilators to be used for SARS-CoV-2 infected patients with high chances of survival is ethically permissible, however, others may argue that it is ethically unacceptable especially without the consent of the patient or his/her family.
Since the emergence of SARS-CoV-2 pandemic, scientists are working day and night to find a potential treatment or vaccine to prevent the spread of the virus. Many anticipate the success of these treatments/vaccines to put an end to this tragic pandemic (19). However, this will not put an end to the currently faced ethical dilemmas. The significant question now will be who will have the priority to receive such treatments or vaccines? The dilemma of ventilators might propagate in case of establishing an effective treatment or an antiviral vaccine. For new vaccines, will priority be given to the most vulnerable to the infection/at higher risk of morbidity or mortality due to SARS-CoV-2 infection or to those who are most likely to benefit from immunization? In other words, will cancer patients be finally prioritized and seen as more vulnerable or will administer it to healthcare providers working in the frontline and interacting with hundreds of infected individuals on daily basis be more justifiable?
Whether it is a ventilator, antiviral medication, or vaccine, the consequences of a particular treatment decision can be afflictive for those excluded from benefit by that decision. Thus, no single person should be burdened to take such hard decisions. The value of well-educated, trained and experienced medical ethicists surfaces here. They are most-fit to balance such choices and guide the medical community to make the most justifiable ethical decisions governed by such specific circumstances. In addition, a clear ethical framework should be generalized and followed on a national level to ensure fairness of treatment. Fairness does not necessarily mean that every patient is provided with the same resources, rather differences in resource allocation, treatment and prioritization of patients is based on ethically justifiable criteria.
The American Medical Association (AMA) Code of Medical Ethics has provided foundation guidance in response to the SARS-CoV-2 pandemic (20). Table 3 lists the AMA Code of Medical Ethics Opinion 11.1.3, which gives guidance for allocating limited health care resources (21). It can be noticed that such guidance is framed broadly and intended to be applicable across a range of settings. A more specific framework is needed specifically to guide and unify the care provided for cancer patients during the current SARS-CoV-2 pandemic.
Table 3. American Medical Association (AMA) Code of Medical Ethics Opinion 11.1.3, Allocating Limited Health Care Resources (20).
Acting and communicating ethically sound decisions should be a priority for healthcare providers during such hard times, and it becomes vital not only to communicate, but to provide resources of education for patients to help them make decisions regarding their treatment. However, during a crisis, the stakes grow higher, and the ethical challenges of communicating both accurately and strategically can be very complicated. Informed consents can be especially challenging. Additionally, in cases of scarce resources, physicians might need to play a proactive role and have premature end-of-life and DNR discussions with their cancer patients (6).
Another complex situation is when healthcare providers caring for cancer patients are called to care for critically-ill SARS-CoV-2 infected patients outside of their specialty and routine clinical practice, especially in a national health crisis (19). Here, physicians are left with a hard paradox of conscience leaving their own cancer patients, who they have been treating for years, juggling with their chances of survival after a long journey of painful procedures and treatment cycles, to fulfill yet another noble role and save many infected patients lives' giving them the opportunity to go back to their lives as healthy as they were before with no permanent negative consequences on their health.
Situation in Jordan
On the 15th March 2020, Jordan had only one confirmed case of SARS-CoV-2 infection (22). Nonetheless, this did not stop healthcare institutions from starting to prepare for a potential health crisis, already witnessed in several countries worldwide at that time. No national guidelines for treating cancer patients were developed, leading individual institutions to take the initiative to develop their own internal policies.
Situation at King Hussein Cancer Center
King Hussein Cancer Center (KHCC) is a standalone cancer center located in Jordan's capital, Amman. It provides comprehensive cancer care for the citizen of Jordan and neighboring countries. The center treats over 6,000 new cases annually; one quarter of which are non-Jordanians.
Given the unprecedented current outbreak and the lack of proper predictions on when such pandemic can be controlled, the diagnosis and treatment of malignant tumors should be carried out in an orderly and safe manner. Guidelines and recommendations on how to manage cancer patients during this pandemic do exist (18, 23). To meet challenges and to optimize quality care, KHCC had put into effect several measures:
To avoid exposing our patients and our healthcare workers to SARS-CoV-2 infection, patients and their companions were screened twice; the day before their scheduled appointments to outpatient clinics, chemotherapy, radiotherapy, or elective diagnostic imaging, patients were screened over the phone by nurse coordinators about any exposure or clinical symptoms that may suggest SARS-CoV-2 infection. On the day of the appointment, all patients arriving at the center were screened again in a specially-designed “Drive-Thru” system where brief history and vital signs were measured.
During the first 2 months of the pandemic, the center decided on adopting “Tele-Clinics.” All scheduled patients were notified the day before not to report to the hospital and that their clinic visits will be made via phone calls by their nurse coordinators and clinicians. During this “Tele-Clinic,” the team assessed patients clinically for all issues related to their cancer or its therapy. Occasionally, patients were requested to report to the hospital for a clinic visit, a drop-in clinic or even to the emergency room (ER). Such clinical encounters were documented in patients' electronic medical records.
Additionally, the center enforced and upgraded a previously established call center. Patients may call 24/7 inquiring about new complaints or issues related to their cancer or its therapy. Senior oncology nurses, who have access to all oncologists and other consultant physicians, operate this call center. Messages were also sent to all KHCC patients not to come to the ER before contacting the call center. Unnecessary ER visits were prohibited using this approach.
Limited Medical Services
During the first few weeks, KHCC limited elective surgeries and limited chemotherapy sessions to potentially curable cancers utilizing regimens not known to cause prolonged immunosuppression. Fortunately, these arrangements were temporary and resulted in minor delays in patients' active therapy. Likewise, the Hospital Ethics Committee updated and approved new modifications to the DNR policy to allow a team of physicians to make DNR decisions if more ICU beds or ventilators were needed (24). Fortunately, such situations were never encountered.
Medication Home Delivery
To avoid difficult commuting to the hospital and to minimize exposure, the center adopted a delivery plan to patients, to distribute newly prescribed and refilled medications. This service was welcomed by both patients and physicians alike. Special arrangements were made to refill narcotics as local rules and regulations prohibit delivering such medications.
Learning from the experience encountered in some European and neighboring countries, the center decided to work during the early months with reduced staffing. Staff not on-duty were asked to stay home to avoid any accidental exposure and lengthy quarantines. An incidence of a single exposure at our center put aside more than 30 healthcare workers including physicians, nurses, dieticians, respiratory therapists, clinical pharmacists, housekeeping, and many others.
As the current SARS-CoV-2 pandemic continues to evolve worldwide, many ethically challenging decisions must be made. This includes treating cancer patients, which might be easily overlooked at such difficult times. Much attention should be given to provide guidance for healthcare providers on delaying or altering cancer treatment plans, allocation of limited resources and patient-physician communication in addition to the importance of on-going discussions between medical ethicists and healthcare providers. The role of qualified medical ethicists and consultants is of paramount importance as they can ensure ethical medical practice during such critical times. However, in Jordan, such expertise are not abundant and the role of medical ethicists is still slowly emerging.
Finally, we provided a summary of the insight from the experience of KHCC, a comprehensive cancer center in this particular region. Overall, it appears that KHCC opted to adopt extreme measures to ensure the safety of patients and healthcare workers alike. As per the recommended triaging strategies (Table 1) it would appear that KHCC followed a mixture of “protecting the most vulnerable” and “prioritization of the most important.”
