To the Editor,
The pandemic of the COVID-19 started in China in December 2019 with a rapid spread
to the whole world. The COVID 19 is associated with different degrees of severe respiratory
illness and might lead to a severe acute respiratory syndrome, which ends in many
cases with death. The spread of the infection between humans occurs via droplets,
contaminated hands or surfaces, with an incubation time of two to fourteen days.
Most countries went through the lockdown to try to flatten the contagion curve quickly.
In these countries, hospitals suspended normal activities to reallocate healthcare
professionals to cope with the pandemic. Furthermore, the paralysis period of the
planned health activity is generating a waiting list of visits and procedures that
must be incorporated into the health process. Although we are experiencing a health
emergency never seen before, we must not forget that it is our ethical and moral obligation
to continue taking care of our patients, not only patients infected with SARS-CoV-2,
because every patient has the right to be cared for their demands and needs.
Patients with chronic pain, such as those with musculoskeletal, neuromuscular or oncological
conditions, have been mostly deprived of the necessary resources to alleviate their
symptoms and make their lives somewhat more bearable. In most countries during lockdown,
patients have been allowed to use only telemedicine services, with the aim of reducing
the risk of contagion. Unfortunately, in the management of these conditions, many
of the treatments are interventional and therefore not accessible. Not performing
or postponing a procedure may lead to morbidity and other chronic sequelae, including
irreparable functional impairment.
Muscle spasticity, chronic musculoskeletal pain as rotator cuff pathologies or chronic
tendinopathies and fasciitis, hip and knee osteoarthritis, entrapment neuropathies,
polyneuropathy (diabetic etc.) or nerve injuries are disabling and have a great impact
on daily activities performance and quality of life.
Adding to the chronic pain and physical disability these patients experience the fear,
anxiety and loneliness due to the restrictive measures adopted to limit outbreaks,
seriously undermining the mental health.
For this reason, it is essential to progressively reactivate health services and ensure
our complete medical support to the population, which obviously include interventional
and ultrasound-guided treatments, such as intra-articular and tendon injections, regenerative
medicine, botulinum toxin for pain and especially for spasticity treatment, etc.
Although there are no references or experiences on how to resume healthcare in a pandemic,
and whether the previously established processes are equally valid and safe for patients
and healthcare professionals, we can still integrate those protocols with higher safety
standards. It would be good to remember that the criteria and protocols for assigning
and defining priorities for access to hospital care (elective, urgent, etc) must be
applied individually and respecting professional ethics.
In the countries that are, albeit partially, exiting lockdown, we suggest the following
recommendations to maintain a high safety standard. Patients infected with SARS-CoV-2
will follow a dedicated path, being preferably treated at COVID-19 blocks/dedicated
COVID-19 hospitals or clinics. Consider establishing triage stations outside or at
least at the facility entrance to screen individuals. The non-COVID service must be
reorganized, reducing the number of patients that can be normally attended, minimizing
gatherings of people and waiting time in wards, consultations or procedural rooms
and to allow time for sanitation between patients.
Patients should be contacted in advance to investigate their clinical conditions and
prioritize, to evaluate any possible exposure to coronavirus, in case to prescribe
diagnostic test (serological or rtPCR), and to inform that they must wear at least
a facemask upon arrival, at the scheduled time, to the facility. Of note, N95/FFP2/KN95
masks with an exhaust valve might not provide infection control, so health care personnel
must change to or cover with a surgical mask.
Although these are not aerosol-generating procedures, many of them take time, so we
recommend the health personnel present in the procedural rooms to always wear non-valve
N95 masks. Health care personnel should always wear personal protective equipment.
A practical guide on how to safely conduct interventional procedures is shown in Figure

Although there are no specific studies on the possible interference of drugs or treatments
for the management of chronic pain in COVID-19 patients, it is important to elucidate
some doubts, especially regarding the use of anti-inflammatory and corticosteroids,
which are currently under discussion. Despite some controversy, there is no evidence
that the use of nonsteroidal anti-inflammatory drugs can increase the severity of
COVID-19, therefore they can be used when needed

.
Although the use of corticosteroids predisposes to a higher risk of infection, the
immunosuppressive effect is dose and time dependent. Low doses of corticosteroids
rarely increase the risk of infections and are not contraindicated for the treatment
of rheumatic diseases, even during this pandemic
2,3
. Likewise, there is no absolute contraindication to the use of corticosteroids for
the Herpes Zoster associated pain. Therefore, low doses oral corticosteroids as adjunctive
therapy, or for local injection of depot formulations, can be used evaluating the
risk and benefits. Every clinician should be alert on appearance of future new recommendations.
In conclusion, safe practice to protect patients and health care personnel is crucial
to prevent the spread of COVID19 and to maintain chronic pain services to provide
effective treatment for patients during this pandemic.
