Chronic Pain Management during the Covid-19 Pandemic: A Scoping Review

Published:December 01, 2020DOI:https://doi.org/10.1016/j.pmn.2020.11.010

      Highlights

      • Chronic pain management during COVID-19 includes adjustments to the patient care model.
      • This scoping review map the evidence of chronic pain during the COVID-19.
      • Telemedicine is useful in the care and monitoring of these patients during COVID-19.
      • We propose a workflow screening and intervention packages according to the severity.

      Abstract

      Background

      The COVID-19 pandemic has led caregivers to modify patient healthcare, with a high impact on patients with chronic pain.

      Aims

      To map recommendations for the management of chronic pain patients during the COVID-19 pandemic and propose a workflow for the management of these patients.

      Design

      This was a scoping review.

      Methods

      The databases searched were PubMed, Embase, CINAHL, Scopus, Cochrane Library, and LILACS. The studies were examined by two independent reviewers. The disagreements between reviewers were resolved through discussion or with a third reviewer.

      Results

      We presented the results in the form of a table, a workflow, and a narrative summary. The search resulted in 13 studies selected for full reading, including one consensus, five guidance documents, two expert panels, one joint statement, two educational flyers, and two free comments. We considered new technologies, including telemedicine. Each pain service needs to establish a screening model, classifying patients according to corresponding severity. Particular attention should be given to patients who use opioids and are at risk of misusing them. Nonpharmacological approaches and pain education should be maintained, considering the use of telehealth.

      Conclusions

      Recommendations for the management of chronic pain during COVID-19 include adjustments to the patient care model. The workflow proposes the use of telemedicine, screening for painful intensity, and the use of color-signaled intervention packages according to severity (green, yellow, and red).
      Many countries have established public health measures implemented in response to the coronavirus disease 2019 (COVID-19) pandemic. For example, these measures have established a limit on how many people gather in public, helping to prevent the spread of COVID-19. Likewise, national and local health public authorities have temporarily suspended the public health services considered nonessential, including outpatient consultations and elective health procedures. The COVID-19 pandemic has affected the health monitoring services offered to patients with chronic diseases, worsening their symptoms or even their mental health (

      ).
      In this context, the management of patients with chronic pain has been significantly affected. Chronic pain is prevalent worldwide and causes physical and psychological suffering. Factors associated with the chronic pain prevalence, such as agingcand the presence of other chronic diseases, match with the factors related to COVID-19, necessitating continuous health monitoring of the patient by a health professional essential during the pandemic (

      The treatment of the patient with chronic pain is complex and involves pharmacological and nonpharmacological therapies. Some of the medications for chronic pain, such as opioids and corticosteroids, can cause changes in the immune system, which can lead to infections such as COVID-19. Despite nonpharmacological therapies being essential to improving the quality of life of these patients, they have limitations when performed virtually. Psychological symptoms such as anxiety, depression, fear, catastrophizing, and suicidal thoughts tend to be exacerbated in times of crisis and tension, requiring greater attention (

      ).
      Treatment interruptions for chronic pain patients due to the COVID-19 pandemic are creating a need for novel therapy alternatives using emergent technologies such as telemedicine. Many questions arise in this process: what criteria to use to perform the screening for virtual or face-to-face healthcare service for patients with chronic pain? How to monitor these patients in a telemedicine context? How to mitigate the risk of COVID-19 in cases of acute and chronic pain and the need for emergency procedures? What measures can minimize the psychological consequences of social isolation in patients who are already predisposed to anxiety and depression?
      Caregivers hope to offer chronic pain patients therapy alternatives that have a lesser impact on treatment, ensuring the monitoring and control of pain and related symptoms. Scientific evidence containing guidelines for the management of patients with chronic pain during the COVID-19 pandemic is scarce in the literature. Preliminary searches on the Prospero website, PubMed, and Cochrane database have found an absence of protocols or reviews on the topic.
      This scoping review gathers all the available evidence and makes it possible to identify gaps in the literature for new primary studies. The objective is mapping all recommendations on the management of chronic pain patients during the COVID-19 pandemic, and proposing a workflow for the management of such patients.

      ).

      Inclusion and Exclusion Criteria

      Publications that met the inclusion criteria were those on the management of patients with chronic pain during the COVID-19 pandemic. For this scoping review, studies published after the pandemic (December 2019) were included. All primary research studies, reviews, meta-analyses, guidelines, and texts published on society websites were considered. There was no language restriction.
      Studies that addressed acute pain or chronic pain outside the context of the COVID-19 pandemic were excluded.

      Data Sources

      The databases searched were PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, Cochrane Library, and Latin American and Caribbean Health Sciences Literature (LILACS). The search for unpublished literature included: sites for pain organizations, the World Health Organization (WHO), the Agency for Research and Quality in Health, the Institute for Healthcare Improvement, and the Digital Library in Network of Theses and Dissertations.

      Search

      The search strategy was as comprehensive as possible, to identify published and unpublished studies (gray literature). A three-step search strategy was used for this review. A limited initial search of PubMed and Embase was carried out, followed by analysis of the words contained in the title and abstract and in the terms of the index used to describe the article. A complete secondary search was performed on all databases included, using the keywords and index terms identified in the initial limited search. To help identify additional studies, we conducted a tertiary literature search by examining the reference lists for all studies included in this review. Appendix 1 shows the sensitive search strategies.

      Selection of Sources of Evidence

      After the searches, all citations were organized in a reference manager. The studies were examined by two independent reviewers based on the inclusion criteria for the review. The selected studies were retrieved for full-text review. Disagreements between reviewers at each stage of the study selection process were resolved through discussion or with a third reviewer.

      Data Extraction and Items

      Data from the articles were obtained using a data extraction tool developed by the reviewers. The extracted data includes the distribution of studies by year, author, title, type of publication, and content.

      Synthesis of Results

      The extracted data are presented in the form of a table, a workflow, and a narrative summary. We used a graphical representation for a workflow using symbols from Business Process Modeling Notation (BPMN) published by Object Management Group (OMG;

      In the consensus paper, the authors describe clinical guidelines focusing on caring for patients in pain during the pandemic. They discuss factors related to drugs that can affect the immune system, and thus make patients with chronic pain more predisposed to COVID-19 infection. It proposes therapeutic recommendations during consultations, the possibility of using telemedicine, biopsychosocial interventions and care during the performance of interventional procedures. The authors ultimately suggest a follow-up visit for the patient with chronic pain during the pandemic (

      In some countries, public health services for patients with pain were interrupted temporarily, with caregivers focusing the available resources on helping patients with COVID-19 in a critical state. Healthcare professionals for patients in pain from Wuhan and Shenzhen, two provinces with high COVID-19 occurrences in China, had to reorganize their healthcare for a patient with high-intensity pain. They share their experiences related to screening patients during the pandemic. Patients were screened at different levels of care, considering the risk and symptoms of COVID-19. They were given prescription medications to manage their pain at home, along with necessary telemedicine support. Patients with severe pain or emergency conditions received immediate treatment at the clinic or were admitted for further tests and treatments (

      The American Society of Regional Anesthesia and Pain Medicine (ASRA) and the European Society for Regional Anesthesia and Pain Therapy (ESRA) have prepared a joint statement containing recommendations for the management of patients with chronic pain. The document proposes to classify the need for care and assess the patient for risk of contracting COVID-19. Another initiative by the ASRA and ESRA societies was the construction of two educational flyers focusing on COVID-19, containing a summary of the best evidence about the management of patients with chronic pain (

      ).
      Regarding interventional pain procedures, the Spine Intervention Society (SIS) published a guide for managing procedures for patients in pain during the COVID-19 pandemic. The guideline has six steps: (1) prioritize alternatives for personal assistance, (2) reschedule elective and non-urgent procedures, (3) prioritize procedures by performing a risk-benefit analysis, (4) prepare the environment for patients at risk of COVID-19, (5) use recommended personal protective equipment (PPE), (6) manage potential exposure (

The author emphasizes that many patients with chronic pain are in the high-risk group due to aging or other comorbidities. The mental health of these patients is also compromised by social distance since anxiety and depression are common in patients with chronic pain (

      An editorial from the Journal of Practical Pain Management included some recommendations for patients with chronic pain during the pandemic. The authors emphasize the importance of effective communication between patients and healthcare professionals in the use of telemedicine. They also share some considerations about the use of opioids and management of anxiety in these patients, in addition to more strict hygiene measures adopted by pain clinics (

      The American Psychological Association (APA) released guidelines on how to perform assessment and psychological intervention for patients with chronic pain during a pandemic using telemedicine as a resource. They emphasized teleneuropsychology, recognized by the APA as a practice with proven results. The guide highlights the main forms of psychological treatment used in a patient with pain, such as cognitive-behavioral therapy, relaxation techniques, mindfulness, and assessment using tools for anxiety, depression, fear, and catastrophic thoughts. They addressed questions about the use of opioids during the crisis, which should be discussed with the patient and a responsible team (

      Workflow for the Management of Patients With Chronic Pain During COVID-19

      This review built a workflow containing the main study recommendations. The workflow proposes that patients with chronic pain have access to telemedicine through telephone calls. During remote care, the provider treats the patient according to pain intensity. The patient is then classified by color, according to severity (green, yellow, or red). Patients without pain or with mild pain are considered elective and receive the green intervention package. Patients with moderate to severe pain are initially considered to be emergent and receive the yellow intervention package. If pain intensity worsens and pain medication fails to reduce it, the patient is considered urgent and receives the red intervention package. Urgent patients need to be assessed for risk of COVID-19 so caregivers can take infection prevention and control measures. The time for patient reassessment must follow the routine established in each service. The authors emphasize that the proposed flow must be adapted to the realities of the situation, respecting local government guidelines (Fig. 2).

      Discussion

      Risk Mitigation and Screening for Patients With Chronic Pain

      The COVID-19 pandemic has affected the worldwide population and placed a burden on chronic pain patients. One of the most effective government measures to avoid saturating the public health system is social distancing, which, in the short term, results in changes in the work processes of health services, such as suspension of elective procedures and outpatient consultations (

      Uncertainty, in the context of actions during a pandemic, occurs because of lack of information regarding the flow of patients, as well as lack of understanding and knowledge about a new disease, its consequences, and its probabilities of spreading. Healthcare professionals need to know how to mitigate risks in the planning of actions to ensure a flattening of the number of patients infected by COVID-19 (

      During the pandemic, patients in chronic pain need to be monitored by a multiprofessional team, even at a distance. At this moment, we need more rigor in the prevention and control of infection, to protect healthcare professionals and patients from the spread of the virus, especially during the asymptomatic phase of the disease, when there are no signs of contamination. Defining criteria for virtual or in-person services and assessing risks are fundamental steps for planning a good service flow (

      ). In elective cases, the authors recommend postponing all procedures, and in cases of consultation, performing it through telemedicine. Cases considered emergent must be defined individually, considering the risks and benefits of the service and procedure. In urgent cases, the patient needs to be attended face-to-face and must be evaluated for the risk of COVID-19, taking appropriate protection and control measures to avoid the spread of disease (

      ), it is recommended that patients with chronic pain who need healthcare undergo strict control and be classified into levels of care based on pain intensity. The first level includes patients with mild to moderate pain, who have relatively clear etiopathogenesis with few comorbidities and are in good condition. This group was typically prescribed pain control drugs at home and telemedicine follow-up. Those who had close contact with diagnosed individuals or were suspected to have COVID-19 were placed under observation during quarantine at home. The second level included patients with mild to moderate pain, those who had symptoms like those of COVID-19, or those who had close contact with individuals diagnosed with COVID-19. The third level included patients in severe pain or undergoing emergencies, who received immediate care. Patients screened at levels 2 or 3 who had any symptoms or suspicion of COVID-19 were referred to an isolation ward for further testing and treatment (

      Use of Technologies to Monitor Patients With Chronic Pain During COVID-19

      The current crisis, although devastating, has shown that health systems need to improve to continue their activities remotely. By immediately reorganizing with the least possible damage to chronic patients, healthcare institutions can advance the incorporation of new technologies into inpatient care. To support these changes, many regulatory measures have emerged with more flexibility. We can use a variety of video communication technologies, many of which are free or inexpensive, including tools from Google, Skype, Twitter, and Facebook (

      Using technology for consultations and monitoring chronic pain symptoms allows patients in stable condition to remain in home isolation, reducing the risk of COVID-19 contamination. Telemedicine is an older term used to refer to technologies and telecommunications systems to administer healthcare to patients geographically separated from providers.

      Safety in the Prescription and Use of Medicines Chronic Pain During COVID-19

      Regarding pharmacological treatments, it should be borne in mind that opioids, such as morphine or fentanyl, can have an immunosuppressive effect, an effect dependent on the dose and duration of administration. The immunosuppression produced can, in case of infection by COVID-19, favor a more severe form of the disease (

      ). In situations of high fever in patients using fentanyl patches, it should be remembered that there may be an increase in the drug's absorption, with the consequent risk of respiratory depression. The same precautions should be taken with patches of other drugs, such as buprenorphine, although the respiratory depressant effects are less than with fentanyl (

      ). During follow-up, the use of positive reinforcement strategies, valuing the efforts made, serves as a motivational stimulus for the patient. Because of changes in treatment during the pandemic, it is essential for caregivers to develop a problem-solving technique around pain management. The approach must identify the causes and consequences of problems, and include solution planning (

      Evidence exists that some cognitive-behavioral therapy approaches are effective for treatment of chronic pain performed remotely. During cognitive-behavioral therapy, patients who find themselves in a vicious cycle, with erroneous thoughts, catastrophizing pain, and dysfunctional behaviors such as kinesiophobia, are encouraged to substitute them for others that bring greater functionality (

      Whenever possible, experimental learning should be included in the session; that is, working with the patient is a task that can help with pain control. Tasks can be hierarchical, starting with the simplest ones, and increasing in complexity as the patient gains self-confidence. Developing tasks helps the patient to re-establish a routine with daily activities that are meaningful to them. Functional gains, even if short, should be valued, and if the patient has space at home, they can take short daily walks. Complementary resources, such as books, websites, and other self-help materials, may be useful as a remote intervention (

      ).
      A limitation of this review is that no primary studies on the topic were found due to the recent nature of the COVID-19 pandemic. The few publications reflect expert opinions and recommendations. Primary studies are needed evaluating the effects of COVID-19 on the clinical and therapeutic follow-up of patients with chronic pain and the appearance of pain secondary to an infection, as well as measuring the repercussions of social isolation on emotional aspects and quality of life of these patients. Future systematic reviews can be conducted to assess the effectiveness of telemedicine during the pandemic in patients with chronic pain.

      Conclusions

      This paper was the first review to address the management of patients with chronic pain during the COVID-19 pandemic. It proposes the organization of a workflow for the management of patients with chronic pain during COVID-19 using telemedicine care, screening for pain intensity, and intervention packages with color coding according to severity.
      In conclusion, recommendations for the management of chronic pain during COVID-19 include adjustments to the patient care model. The use of technologies, especially telemedicine, was considered in the studies. Each pain service needs to establish a screening model, classifying patients according to severity. Urgent cases, which require face-to-face assistance, need to be treated in a way that minimizes the risk of COVID-19. Infection prevention and control measures must follow the recommended government guidelines. Particular attention should be given to patients who use opioids and are at risk of misuse. Nonpharmacological approaches and pain education should be maintained, considering the use of telehealth.
