Chronic pain is a highly prevalent and disabling chronic condition, which requires an interdisciplinary approach to optimize patient functioning and wellbeing [14,35,65]. With the onset of COVID-19, there have been substantial challenges to the delivery of chronic pain care and an increased need for eHealth. Given this considerable demand and shift in practice, we surveyed 100 BC physicians to identify current barriers and needs to support the provision of chronic pain care, and to assess the use and interest in eHealth technologies within the context of the COVID-19 pandemic. The most prominent barriers that emerged were a lack of access to interdisciplinary treatment and allied health support, challenges related to opioid prescribing and management, and a lack of time to manage the complexities of chronic pain. Although the vast majority of physicians expressed interest in employing a diverse array of eHealth technologies, the present findings suggest that several barriers to implementation remain, with very few providers expanding beyond virtual visits and electronic medical records in their daily practice.
Interdisciplinary Pain Support and Pain Education
Over 90% of surveyed physicians reported a lack of interdisciplinary team support, difficulty identifying community pain resources, and challenges managing patients with co-occurring mental health conditions. Additionally, nearly all (88%) physicians indicated a need for more information on community-based pain resources for their patients. These concerns were echoed and elaborated upon in the free-response portion, with more than half of physicians expressing a lack of patient access to pain specialists, allied health professionals, and non-pharmacological treatment options. Physicians largely attributed these problems to a shortage of service providers, long waitlists, and a lack of public funding for allied health services.
It should be noted that while these barriers are not new, the consequences of limited access to, and knowledge of, community resources and interdisciplinary services may be particularly detrimental in the context of the COVID-19 pandemic. During the pandemic, individuals are experiencing numerous psychosocial stressors including increased social isolation, restricted physical activity, and financial stress, among other challenges [35,66]. These stressors are likely to exacerbate the psychosocial comorbidities associated with chronic pain (e.g., anxiety, depression), making access to interdisciplinary pain care and a biopsychological approach even more crucial [55].
Opioid Prescribing and Management
Concerns with prescribing opioids (sometimes or always = 91%) and difficulty assessing risk for opioid abuse (sometimes or always = 80%) were also endorsed by most of the sample. These concerns were elaborated on in the open-ended responses, with several physicians expressing a need for more comprehensive guidelines that allow for clinical judgement and flexibility. Due to the perceived restrictiveness and ambiguity of the guidelines, physicians expressed fear of being audited, hesitancy to take on patients with opioid use, and challenges tapering doses. Barriers pertaining to vague guidelines and fear of sanctions for prescribing opioids are consistent with the concerns that emerged in a recent qualitative study of primary care providers in Ontario, Canada [30]. Current guidelines suggest that interdisciplinary support should be offered for patients who experience difficulty with tapering/cessation [67,68]. Yet, as conveyed in the present research, there is a scarcity of interdisciplinary pain clinics and affordable allied health options to support opioid tapering/cessation. To achieve equitable delivery of pain care in the midst of the opioid crisis, physicians require clear and supportive protocols, along with improved knowledge for non-pharmacological alternatives [30]. The high prevalence of these concerns is not surprising, in light of not only an opioid epidemic but also the COVID-19 pandemic. Indeed, opioid use has been linked to worsened outcomes for COVID-19 patients [69] and there has been a surge in opioid-related abuse and overdose deaths, further complicating prescribing decisions [70,71].
Lack of Time
Regarding clinical assessment of chronic pain, the most frequently endorsed barriers pertained to lack of time. Over 80% of physicians reported sometimes or always experiencing a lack of time for shared decision-making with patients, as well as a lack of time to review and discuss patient-reported data (i.e., intake measures and PROs). This barrier was also reflected in the open-ended responses, with physicians expressing that lack of time and remuneration for appointments reduced their ability to assess and manage the complexities of chronic pain.
Although this barrier of time is not unique to chronic pain, when combined with the high demand (e.g., frequent and complex visits) and perceived lack of support/knowledge in pain management, insufficient time likely places a considerable strain on primary care providers and their ability to effectively deliver pain care. Further, as previously noted, with the pandemic we have seen a restriction of healthcare services, increased clinic volumes, and higher rates of chronic pain placing further demand on providers’ already limited time [34,35]. In addition to adding more primary care providers to the system, another possible way to help alleviate this time pressure is to adjust the funding model. For example, BC has already introduced financial incentives for primary care providers who treat patients with chronic illnesses such as diabetes and hypertension [72–74] and this could be expanded to include chronic pain.
eHealth
A total of 82% of participants expressed interest in adopting an eHealth platform to assist with pain care, with the greatest interest in technology for automated collection and scoring of patient-reported measures, decision support, patient-generated summaries, medication tracking, and referrals to community-based providers. These features could help alleviate several of the barriers to pain care raised in the present study. For example, by automating certain clinical tasks, physicians can redirect their limited time to other aspects of patient care [75–77]. One example of the successful automation of clinical tasks is the Collaborative Health Outcomes Information Registry (CHOIR; https://choir.stanford.edu) system - a web-based application used actively and widely in the United States to track, monitor, and visualize health outcomes for patients with chronic pain.
Similarly, for providers practicing in low-resource, rural and remote areas, eHealth technology can offer unique benefits that may address several other barriers raised in the present study (e.g., lack of interdisciplinary support, limited pain knowledge) [78]. For instance, Project ECHO™ is a knowledge-sharing network for pain providers initiated in Ontario, Canada and has recently expanded to other provinces. Specifically, clinical experts are connected with primary care providers through telehealth technology to share best practices in pain management, overcome geographical barriers to education, and increase providers’ competency and confidence in treating chronic pain [78–80]. Participation by healthcare providers in Project ECHO™ is associated with improvements in knowledge regarding chronic pain assessment, treatment practices, and opioid prescribing [58,80].
The COVID-19 pandemic has rapidly expanded interest in, and utilization of, virtual care [81–83]. Yet low adoption of a range of eHealth technologies were found in the present study. For example, despite great interest in remote collection of patient-reported intake and outcome data, only 21% and 14% of physicians endorsed current use of these technologies, respectively. This low adoption rate is in stark contrast to the rapid uptake of virtual patient-visits [51]. In the present study, physicians frequently indicated that the software was too complicated, too expensive, and/or they were unaware of the options available to them. These concerns may be partially attributable to physicians receiving little to no formal education on eHealth technology during medical school [84,85]. Moreover, several physicians stressed that any eHealth platform that collects patient intake and outcome data would need to integrate with EMR for successful implementation into their practice. As such, improved design, awareness, funding, and training are required to achieve successful implementation of eHealth technology in routine practice. Indeed, as advocated by Houwink et al. [86], primary care providers need to be “supported, educated, and involved in all processes, from the development of effective eHealth solutions to their implementation in regular care” (pp.109).
Lastly, the findings offer a reminder that modified or non-technology options are still required for certain patient populations, such as those with cognitive limitations or without internet access. For example, in Canada there are large variations in who has internet access. Specifically, the most recent Canadian data indicates that 98.6% of households in urban areas are able to access broadband internet services, compared to just 45.6% in rural households and 34.8% in First Nation reserves [87]. Despite these realities, eHealth continues to show promise in closing the gaps in access to health care and improving physician throughput.
Strengths, Limitations and Future Directions
Although participants in the current study were mostly primary and urgent care practitioners, this reflects the physician population most often tasked with chronic pain management in Canada. Moreover, we captured diverse perspectives by recruiting rural and urban physicians practicing in a range of healthcare settings across the province, with varying degrees of chronic pain experience and knowledge. Nonetheless, the nature of our sample precluded any formal statistical comparisons between practice settings, health authorities, and areas of specialty. Additionally, although a strength of this research, data collection occurred approximately one year into the COVID-19 pandemic and, as such, perspectives and eHealth adoption rates may change as the threat and impact of COVID-19 shifts over time. Future research should continue to explore physician experiences within and outside of Canada, and include the perspective of allied health practitioners who also see a large proportion of people with chronic pain in their practice.
