Abstract
Background:
The COVID-19 pandemic has led to unprecedented challenges and restrictions in surgical access across Canada, including for breast reconstructive services which are an integral component of comprehensive breast cancer care. We sought to determine how breast reconstructive services are being restricted, and what strategies may be employed to optimize the provision of breast reconstruction through a pan-Canadian evaluation from the providers’ perspective.
Methods:
This was a cross-sectional survey of Canadian plastic and reconstructive surgeons who perform breast reconstruction. The 33-item web-based questionnaire was developed by a pan-Canadian working group of breast reconstruction experts and disseminated via email to members of the Canadian Society of Plastic Surgery. The questionnaire queried respondents on the impact of the COVID-19 pandemic and associated restrictions on surgeons’ breast reconstruction practice patterns and opinions on strategies for resource utilization.
Results:
Responses were received from 49 surgeons, who reported practicing in 8 of 10 Canadian provinces. Restrictions on the provision of breast reconstructive procedures were most limited during the First Wave of the COVID-19 pandemic, where all respondents reported at least some reduction in capacity and more than a quarter reporting complete cessation. Average reported reduction in capacity ranged from 31% to 78% across all 3 waves. Autologous, delayed, and prophylactic reconstructions were most commonly restricted.
Conclusion:
This study provides a pan-Canadian impact assessment on breast reconstructive services during the COVID-19 pandemic from the providers’ perspective. To uphold the standards of patient-centred care, a unified approach to strategically reorganize health care delivery now and in the future is needed.
Introduction
The COVID-19 global pandemic has led to unprecedented challenges in health care delivery, threatening access to surgical and medical services across all sectors. For over 25,000 women diagnosed with breast cancer annually, the impact of the pandemic on our Canadian health care system has resulted in significant changes from the standard of care delivery. 1 Comprehensive breast cancer care requires timely multidisciplinary assessment, evaluation, and consideration for multiple treatments including ablative surgery, systemic therapy, and radiation therapy. Breast reconstruction is an integral component of cancer care, recognized as an important option for women undergoing total or partial mastectomy. 2 However, this is considered an elective component of breast cancer care, and thus may be delayed in situations of limited capacity. 3 -6 Limited access to breast reconstruction in Canada precedes the COVID-19 pandemic. 7 With the advent of recent health care restraints on surgical services and inpatient care, breast reconstruction resources will be further restricted.
Breast cancer survivors directly derive great health benefits from immediate breast reconstruction (IBR) post mastectomy, with substantial improvements in their quality of life. 8 -10 Immediate breast reconstruction is performed at the same time as the ablative surgery, allowing for a decreased number of surgeries and improved aesthetic outcomes when compared with delayed breast reconstruction (DBR). 11 From a patient’s perspective, IBR decreases psychosocial distress experienced following mastectomy, decreases body stigma, and improves social and emotional well-being. 12 -15 Respecting the patient’s autonomy and optimizing the outcome of the reconstruction is an important component of the associated improvement in their quality of life. From a societal perspective, the individual benefits of decreased surgery and improved social functioning portends a faster return to pre-cancer function. In a single-payer system, decreased Operating Room(OR) utilization allows those resources to be used for another individual, allowing greater access to surgical care. Health economic research on IBR supports this, with IBR shown to be cheaper and more cost-effective than DBR. 16 -19
There have been severe and fluctuating restrictions in surgical access across Canada during the COVID-19 pandemic. As an integral component of breast cancer care, we sought to determine whether and how breast reconstructive services are being restricted with a pan-Canadian evaluation of surgical access from the providers’ perspective. Furthermore, we sought to determine what strategies are being, or may be, employed to optimize the provision of breast reconstruction during the pandemic.
Methods
Study Design and Population
This was a cross-sectional survey of Canadian plastic and reconstructive surgeons who perform breast reconstruction for patients with breast cancer. A voluntary response sampling methodology was used. Members of the Canadian Society of Plastic Surgery (CSPS) were invited to participate via email invitation distributed to the CSPS email list-serv. Surgeons were contacted and invited to participate twice, 10 days apart. Questionnaires were disseminated and responses collected in May 2021 using Qualtrics, a web-based survey platform. Responses were received anonymously.
Questionnaire
The survey questionnaire contained 33 items that enquired about the impact of COVID-19 pandemic and associated restrictions on surgeons’ breast reconstruction practice patterns. Our questionnaire also queried surgeons on their opinions regarding the best strategies for resource utilization during a global pandemic or periods of limited resources. Questions included numeric, multiple-choice, and free-text responses. The questionnaire was developed in consultation with a pan-Canadian working group of breast reconstruction experts and tested for content and branching logic prior to dissemination. Results were analyzed using descriptive statistics.
Results
Demographics
A total of 49 plastic and reconstructive surgeons completed the questionnaire. Ten surgeons responded and indicated that breast reconstruction is not part of their clinical practice. This represents a response rate of 20.8%. Survey respondents had surgical practices located in 8 of 10 Canadian provinces; Nova Scotia, Newfoundland, and Labrador were not represented. The largest proportion of responses was from surgeons who practiced in British Columbia (28.6%) and Ontario (38.8%). A quarter (24.5%) of respondents’ report practicing solely in the community, 38.8% practice solely in an academic setting, and 30.6% practice in both community and academic settings. The reported proportion of respondents’ practices dedicated to breast reconstruction ranged from 5% to 97%, with an average of approximately half (46%) dedicated to breast reconstruction. Respondents reported performing an annual average of 41 IBR cases (range 0-300 cases/year) and 20 DBR cases (range 0-100 case/year) prior to the COVID-19 pandemic.
Practice Changes and Restrictions Over the Course of COVID-19 Pandemic
During the first wave of the COVID-19 pandemic in Canada, defined as the time period between March and April 2020, respondents reported an average reduction of 78% in the volume of breast reconstructive cases in their practice (Figure 1). To note, during this time period, more than a quarter (27.4%) of respondents reported a complete cessation of breast reconstruction cases in their practice, and all respondents reported at least some reduction in capacity of their breast reconstruction practice (minimum 5%). During the second wave, defined as Autumn of 2020 and Winter of 2021 (November 2020-February 2021) respondents reported an average of 31% reduction in breast reconstruction cases. No respondents reported a complete cessation of breast reconstruction cases during this wave and 8% of respondents report operating at full capacity. Surgeons saw an average reduction of about half (49%) of their breast reconstruction practice during the third wave of the COVID-19 pandemic, defined as Spring 2021. Reported restrictions due to COVID-19 pandemic response were heterogeneous, ranging from 0% to 100% reduction in capacity across all 3 waves.

Current State of Breast Reconstruction Provision in Canada
Currently, a majority of respondents (70.6%) report restrictions, in some capacity, on the provision of elective surgery at their site of primary practice, and 60.8% of respondents report that these restrictions include the provision of breast reconstruction, as compared to standard care. In a free-text response box, common reported themes included restrictions on the delivery of free flaps (eg, deep inferior epigastric perforator flaps) and/or procedures that require hospital admission, postponement of DBR, and restrictions on prophylactic mastectomies with IBR. One surgeon described, Currently [we are] only allowed to offer [breast reconstruction to] healthy patients with outpatient procedures. No complex reconstructions. All [a]utologous reconstruction has been put on hold since March 2020 (eg, no flaps [because] they require admission). Patients with immediate [breast] reconstruction who are not an ASA 1 or chose flap surgery are now all delayed reconstruction.

Light bars indicate services that respondents believe should be offered to patients; revision surgery is defined as nipple reconstruction or revision surgery including fat grafting, dog ear excision; alloplastic BR is defined as BR with a tissue expander or implant; second-stage surgery is defined as tissue expander exchange to permanent implant. DBR indicates delayed breast reconstruction; IBR, immediate breast reconstruction; RS, revision surgery.
Strategies to Optimize Resource Utilization
Respondents were asked to highlight strategies they have implemented or believe would be possible to implement to reduce the burden of resources required for providing oncologic breast reconstruction. Strategies were grouped into 4 themes: (1) strategies for triage and patient selection; (2) strategies for shifting or consolidation of clinic and operating room resources; (3) peri-operative management strategies; and (4) surgical management strategies. Respondents could select multiple strategies for each theme. Results are reported in Table 1. For patient selection, strategies most commonly reported were the use of preoperative COVID-19 testing for all surgical patients (49.0%) and the use of neoadjuvant chemotherapy or endocrine therapy (40.8%) to facilitate conversion from mastectomy to partial mastectomy or to delay surgical resection. Half (49.0%) of respondents favoured a shift in the allocation of operating room time between plastic surgeons and surgical oncologists for IBR cases. Shifting of reconstructive services to outpatient facilities was favoured or applied by 30.6% of surgeons, while sharing of patients and operative resources among plastic surgeons was endorsed by 26.5%. The most favoured peri-operative and surgical management strategies were to institute enhanced recovery after surgery protocols (49.0%) and to restrict types of procedures offered (42.9%), specifically limiting the use of autologous breast reconstruction. Other supported surgical strategies included the promotion of oncoplastic reconstruction (40.8%) and planned staging of the reconstruction with insertion of a temporary prosthesis (38.8%).

Discussion
This survey-based study provides a pan-Canadian description of restrictions on breast reconstructive services during the COVID-19 pandemic, inclusive of providers with a dedicated breast reconstructive practice and those with a lower volume of cases practicing across community and academic settings. This study supports that, throughout the pandemic, breast reconstructive services have been significantly restricted across Canada, with fluctuating yet persistent limited delivery of care. Over the last 18 months, complete restoration of breast reconstructive services was briefly available for fewer than 10% of providers across Canada. During the most recent contraction of resources, in Spring 2021, the provision of breast reconstruction is reduced to approximately half of full capacity. Microvascular reconstruction, delayed and prophylactic reconstructions of any type, and other procedures necessitating inpatient care continue to be the most commonly restricted. Strategies endorsed for the safe delivery of reconstructive services aim to reduce the risk of viral transmission, maximize utilization of operative time, and optimize the efficiency of peri-operative care.
During this third wave of the pandemic, immediate alloplastic breast reconstruction with tissue expanders or implants were the most commonly reported type of breast reconstructive services available by Canadian plastic surgeons, with most restrictions placed on autologous breast reconstruction. These findings echo reports from a survey study of the American Society of Plastic Surgeons where half of respondents reported complete restriction on autologous breast reconstruction in their institution of practice. 20 These findings align with the recommendation by 42.9% of our respondents to restrict the types of breast reconstructive services offered to patients as a strategy to optimize resource utilization. However, these recommendations contrast consensus opinions from Imperial College/Northwest-London Oncoplastic Breast multidisciplinary unit in the United Kingdom that support immediate autologous breast reconstruction to be safe and feasible during a pandemic. 21 This discordance among Canadian providers between reconstructive services that are currently available and those that should be available is likely reflective of variations in hospital capacity across provinces. Restoration of the complete spectrum of breast reconstructive services may be achieved in a safe, equitable, and timely manner with the strategic application of best practice standards according to local institutional capacity. Strategies outlined in this study, supported by other international groups, 20,22 provide a roadmap for collaborative discussion between providers and hospital administrators to reduce the burden of resources required for microvascular reconstruction.
In addition to restrictions on autologous breast reconstruction, our Canadian respondents report substantial restrictions on the provision of DBR, where less than one-third are able to offer DBR of any type (alloplastic or autologous). This is in contrast to our American counterparts, where less than 5% of plastic surgeons report restrictions on delayed procedures. 20 Notably, as a result of the Canadian response, this cohort of patients awaiting delayed reconstruction will suffer unacceptably long wait times given their limited access to reconstruction preceding the COVID-19 pandemic. 3 This rising unmet demand is unfavourable from both an individual and societal perspective, contributing to the psychosocial hardships of breast cancer survivors 11 -14 and leading directly to increased health care costs for Canadians. 15 -18 With over a decade of multi-year wait times, this cohort of patients with breast cancer merit recognition of their suffering with resources justified to meet their reconstructive needs as hospitals’ restore health care services post-pandemic.
Over the course of the pandemic, providers across Canada have adapted their reconstructive practices to optimize the use of existing resources. Strategies to delay the need for surgical access with adjuvant therapy were commonly employed, reflecting the importance of coordination with the multidisciplinary team and administrators allocating resources. This delay of demand for surgical care provides flexibility and facilitates the organized allocation of resources based on predicted needs. However, with uncertainty in the duration and severity of restrictions, this strategy only provides short-term relief with an inevitable surge in demand. Another important strategy utilized is the planned staging of reconstruction, further contributing to delayed exponential growth in the demand for resources to complete the second phase of the reconstruction. These anticipated resource demands compound those of delayed reconstruction patients previously outlined and those of patients awaiting second-stage surgery, both with unfavourable long-term consequences for our patients. 14,23 This study provides evidence foreshadowing the impending backlog of demand for reconstructive services in Canada. Despite demonstrated efforts to employ strategies within the context of institutional restrictions, providers will require tremendous support from administrators and policymakers to restore the standard of care in breast reconstruction.
Limitations
These data must be interpreted in the context of the survey study design. This cross-sectional assessment of restrictions in breast reconstructive services is limited to a single period of time within the context of fluctuating hospital capacity across Canada, with an inherent risk of recall bias. Diversity in practice location, type, and volume of breast reconstruction among the survey respondents supports this study as representative of a pan-Canadian perspective. However, due to the anonymity of responses, a non-responder analysis was incomplete. Institutional-level data on service provision and restriction would further supplement the evidence provided on delivery of care. Evaluation of these structural and process measures, in concert with patient-reported outcomes, is the subject of a future study on reconstructive outcomes during the pandemic.
Conclusion
This study provides a pan-Canadian impact assessment on breast reconstructive services during the COVID-19 pandemic from the providers’ perspective. Despite fluctuations in hospital restrictions, breast reconstruction has been persistently limited across Canada since the onset of the pandemic in March 2020. To uphold the standards of patient-centred care, a unified approach to strategically reorganize health care delivery now and in the future is required given this current environment of fluctuating and prolonged strains on the health care system.
