METHOD: A national survey was performed among all 148 hospitals providing CRC services. Information was collected about changes in referrals, diagnostic, staging and therapeutic procedures, as well as whether there was access to a ‘cold site’ (a hospital facility free of COVID‐19). Clinicians in each hospital were also asked to give the ‘single most important lesson learned’ about keeping services safe and effective. RESULTS: Full responses were received from 123 (83%) hospitals, and information about ‘cold sites’ was available for 146 (99%). Eighty hospitals (54%) had access to a ‘cold site’ and this was increased in regions with higher COVID‐19 infection rates (p <0.001). Of the 123 responding hospitals, 105 (85%) indicated that referrals of patients with suspected CRC had dropped by at least 30%, and 69 (56%) indicated that treatment plans were altered in at least 50% of CRC patients. However, ‘cold site’ availability protected the capacity for diagnostic colonoscopy (p = 0.013) and CRC resection (p = 0.010). Many ‘lessons learned’ highlighted the importance of adequate structural service organization, often mentioning ‘cold sites’ and regional coordination as examples, good communication and triage of patients based on clinical urgency. CONCLUSION: Access to ‘cold sites’, as well as regional coordination, clear communication and strong leadership, were found to be pivotal in maintaining capacity for diagnosis and treatment of CRC during the COVID‐19 surge. The first peak of the COVID-19 pandemic had a large impact on colorectal cancer (CRC) services in many countries. Early reports suggest that patients undergoing cancer treatments were at increased risk of COVID-19 infection, the requirement for critical care, and mortality [1] [2] [3] . Despite the roll-out of vaccination programmes, the COVID-19 pandemic continues to disrupt CRC services due to the direct risks of COVID-19 to vulnerable CRC patients as well as the diversion of resources to other areas in the healthcare system, increased levels of staff sickness, and the need for social isolation among the clinical workforce [4, 5] . Diagnostic delays as a result of suspended screening programmes, reduced access, and availability for diagnostic services and changes in health-seeking behaviours due to fear of exposure to COVID- 19 have sparked concerns that a rise in late cancer diagnoses may increase cancer mortality in the long term [6] . For example, in the UK, urgent primary care referrals for suspected cancer dropped by 60% in April 2020 compared with the previous year, and modelling exercises have estimated that diagnostic delays may lead to an increase of up to 16.6% in avoidable deaths from CRC [7, 8] . To maintain treatment capacity and to protect patients during the COVID-19 pandemic, cancer services have increased the use of nonoperative treatments [9] and created 'cold sites' for elective treatments [10] . 'Cold sites' are hospital facilities set up to be COVID-19 free, or almost so. This environment was achieved in the initial wave by screening patients for COVID-19 prior to admission, strict segregation of elective and emergency surgical services, and geographical separation of the 'cold' facility from where patients with COVID-19 were treated. More recently, regular staff testing for asymptomatic COVID-19 has also been used [11, 12] . The National Bowel Cancer Audit (NBOCA) carried out a national study of CRC services during COVID-19 to map the response of the National Health Service (NHS) in England and Wales. The primary aim of the study was to assess the capacity for elective CRC surgery and diagnostic colonoscopy in relation to the provision of 'cold sites' during the first peak of the pandemic. These results were compared at a regional level to assess whether the availability of 'cold sites' for CRC surgery varied according to local COVID-19 infection rates. We also created a national snapshot of the impact of the pandemic on other aspects of CRC diagnostic and treatment pathways in England and Wales. In addition, we asked the CRC providers to describe the 'single most important lesson learned' about how to make services for CRC patients as safe and effective as possible during the COVID-19 pandemic. We present these lessons according to whether they relate to the diagnostic and staging aspect or the therapeutic aspect of the CRC treatment pathway, COVID-19-specific measures, the structural organization of CRC services, or leadership and management (human factors). Total confirmed 'cumulative' COVID-19 diagnoses from 11 January 2020 to 15 April 2020 were obtained for English local authorities and Wales [13] . For England, local authorities were mapped to the 21 regions that represent the NHS Cancer Alliances, the organizational structures set up to enable cancer care to be more effectively planned across local cancer care pathways [14] . Regional cumulative COVID-19 rates to 15 April 2020 per 100 000 population were calculated using English and Welsh population estimates [15] . All 148 NHS English hospital trusts and Welsh hospital boards providing CRC care in England and Wales according to the NBOCA were requested in June and July 2020, via a national survey, to provide information about the CRC services they provided in mid-April 2020 (see Appendix 1). The survey was distributed to leading NBOCA clinicians, and was therefore predominantly completed by consultant colorectal surgeons. NHS hospital trusts and hospital boards are the legal entities responsible for providing publicly funded secondary care in England and Wales, respectively. A hospital trust or hospital board can consist of one or more hospital sites, but in this paper, 'hospital' is used to refer to a hospital trust or hospital board. The requested information covered five COVID-19-related changes with respect to numbers of referrals for newly diagnosed patients, planned CRC treatments, delivery of CRC services, access to COVID-19 surgical 'cold sites', and the 'single most important lesson learned' (Appendix 1). The 'lessons learned' were provided as free text. The regional cumulative COVID-19 rates were grouped into high and low based on a threshold corresponding to the overall median value of cumulative COVID-19 rates for the English Cancer Alliances and Wales. English hospitals were assigned to a group according to which Cancer Alliance they are in. The two hospitals with missing data for access to a 'cold site' were considered not to have such access for the purposes of further analysis. The primary outcome for the study was the capacity to maintain elective CRC surgery and diagnostic colonoscopy dependent on the provision of 'cold sites'. Chi-square tests were used to compare proportions. Spearman's rank correlation coefficient was used to test the association between cumulative COVID-19 rates and access to surgical 'cold sites'. The level of statistical significance was set at 0.05. The free-text responses to the 'single most important lesson learned' were independently analysed by two reviewers (JB and JvdM) in three steps. First, responses were broken down into statements. If responses contained more than one statement these were analysed separately. Second, the statements were grouped into broader 'lessons learned'. Each statement could link to multiple 'lessons learned' if applicable. Third, the 'lessons learned' were organized into five categories (diagnostic and staging pathway, treatment pathway, COVID-specific measures, structural organization, leadership and management) and linked to five generally recognized domains of healthcare quality which were defined a priori: 'effectiveness' (delivering care to all patients who are expected to benefit); 'safety' (avoiding harm to patients from care that is intended to help them); 'efficiency' (avoiding waste of facilities, equipment and staff); 'responsiveness' (responding to patients' specific conditions and situations); and 'patient experience' (providing care that is respectful and guided by patient preferences) [16] . The 'lessons learned' could link to more than one domain as appropriate. Disagreements were resolved through discussion. Full responses were received from 123 (83%) hospitals. Information about 'cold sites' was available for 146 (99%). Overall, 80 of the 148 hospitals (54%) were found to have access to 'cold sites' for CRC surgery (Table 1, Figure 1 ). Over half of these (41 hospitals), reported access to a 'cold site' in the independent sector. There was considerable regional variation among the 21 English regions and Wales. In four of these 22 regions (18%), 25% or fewer of the hospitals had access to a 'cold' site, and in four regions (18%), all hospitals had access to such a site. There was strong evidence of an association between the regional cumulative COVID-19 infection rate per 100 000 population and the proportion of providers reporting access to surgical 'cold sites' (p < 0.001) (Figure 2 ). The majority of hospitals reported a significant reduction in the number of urgent referrals: only 6 of the 123 hospitals (5%) that responded reported no reduction (more than 90% of the usual number of referrals), 12 hospitals (10%) reported a small reduction in numbers (71% to 90% of the usual number), 95 hospitals (77%) reported a large reduction in numbers (20% to 70% of the usual of number) and 10 hospitals (8%) reported very few referrals (0% to 19% of the usual number). Of the 123 responding hospitals, 69 (56%) indicated that, in response to COVID-19 risks, treatment plans had been altered in more than 50% of their patients ( Figure 3 ). Again, considering changes that affected more than 50% of their patients, 61 hospitals (50%) reported delays in treatments due to COVID-19 infection risks, 61 (50%) delays in tissue diagnosis and radiological staging, and 57 (46%) delays in treatment due to diversion of resources. The COVID-19 pandemic had a smaller impact on the length and type of chemotherapy treatment (47 hospitals (38%) reported changes in more than 50% of their patients), and on the use of temporizing treatments (23 hospitals (19%) reported changes in more than 50% of their patients) such as the stenting of obstructing cancers and radiotherapy for rectal cancer with a 'long wait'. The majority of providers reported that CRC services were running at less than 70% of their usual capacity for diagnostic and therapeutic activity ( Table 2) . Among the 123 responding hospitals, complete cessation of activity (0% to 10% of usual activity) was reported by 95 hospitals (77%) for diagnostic colonoscopy, 72 (59%) for lung resection, 67 (54%) for liver resection, 28 (23%) for CRC resection, 22 (18%) for adjuvant chemotherapy, and 21 (17%) for neo-adjuvant chemoradiotherapy. There was no statistically significant association between high regional COVID-19 rates and the provision of CRC services (Table 2) . However, providers with access to 'cold sites' for CRC surgery were significantly more likely to retain higher levels of activity for diagnostic colonoscopy (p = 0.013), CRC resection (p = 0.010), lung resection (p = 0.026), neo-adjuvant chemoradiotherapy (p = 0.010) and adjuvant chemotherapy (p = 0.050), with weaker statistical evidence for a similar difference for liver resection (p = 0.096) ( Table 3) . We received 108 responses, from which 154 statements were extracted. If responders had included multiple statements these were During the first 2 months of the COVID-19 pandemic there was considerable regional variation in the availability of 'cold sites' for CRC surgery in England and Wales, with just over half of NHS hospitals reporting access. 'Cold sites' were more likely to be available in regions with higher COVID-19 rates, and their availability was significantly linked to higher retained levels of CRC surgery. About three-quarters of hospitals providing CRC services reported a major drop in referrals, and just over half indicated that treatment plans were altered in at least 50% of their patients, mainly because of delays in staging investigations and initiation of treatments. However, the availability of a 'cold site' also protected diagnostic colonoscopy activity, as well as other therapeutic activities including oncological treatments and the surgical management of advanced disease. Many of the 'lessons learned' related to the structural organization of CRC services, with the setup of 'cold sites' often being mentioned as an example, and to human factors such as how the services were managed and led, highlighting the importance of communication and regional coordination. The 'lessons learned' that had a direct clinical perspective focused more frequently on the diagnostic and staging pathways than on the treatment pathway, reflecting major concerns about delays in the initiation of treatment for CRC. TA B L E 1 Response rate and access to 'cold sites' for colorectal cancer surgery by English region and Wales, ranked according to cumulative COVID-19 rate per 100 000 population mid-April 2020 The main limitation of this study is that the mapping of 'cold sites' This study had an excellent response rate and therefore provides a representative picture of NHS hospitals delivering CRC services in England and Wales. An earlier national survey pertaining to UK CRC services during the pandemic included just 36 hospitals and primarily evaluated adherence to national guidelines [17] . A key finding from this work, in line with other studies [18] [19] [20] , is the pivotal role of 'cold sites' in maintaining CRC surgery. This is further supported by recent findings that patients undergoing elective cancer surgery at COVID-19 'cold sites' have lower rates of pulmonary complications and mortality [10] . As mentioned earlier, 'cold sites' were not precisely defined at the time we collected our data. Since, a broad definition has emerged that describes 'cold sites' as a COVID-19-free environment, either as a separate hospital or as separate facilities within a hospital, including an elective operating room, critical care and inpatient ward areas that are not shared with patients with COVID-19 [10] . Additional measures employed to maintain these 'cold sites' have included pre-and postoperative self-isolation for 14 days, preoperative COVID-19 testing, including chest imaging, personal protective equipment (PPE) and workforce isolation with frequent and efficient point-of-care testing [11, 12] . Single-centre studies have reported the use of nearby independent sector facilities, as found within our study [11, 12, 21] . Our results have also shown that 'cold sites' have a pivotal role in maintaining diagnostic activity, which is especially important given the 90% drop in endoscopy numbers in the initial phase of the pandemic [22, 23] . The risk of contracting COVID-19 during colonoscopy has subsequently been deemed low [24] . Widespread disruptions to activity within CRC care pathways were reported, especially with respect to treatment delays and adjustments to standard pathways of patient care. Our results have shown that treatment plans tended to be delayed rather than alternative non-conventional treatments used. This is an important finding, as delays in treatment of just 4 weeks have been shown to have negative impacts on survival [25] . It is important to note that changes to planned CRC treatments and activity levels were independent of regional COVID-19 infection rates, which is in line with earlier findings [26] . This may be explained by the greater availability of 'cold sites' in regions with higher COVID-19 rates. However, it could also be explained by the impact of rapidly changing national guidelines during the first wave of the pandemic [27] [28] [29] [30] . For example, initially only emergency and urgent CRC surgery were prioritized and laparoscopic surgery was discouraged [27, 31] . Ethical issues, especially those regarding the fairness of the allocation of resources that became scarce during the COVID-19 pandemic, need to be explicitly addressed [32] . This is in line with our finding that many 'lessons learned' reported by participating clinicians related specifically to decisions about access to treatments. Strategies to minimize harm and prioritize patient care include using frailty and prognostic scoring in primary and secondary care in order to identify those patients for whom palliative care may be more appropriate [33] . Adjustments to treatment pathways could also include, for example, changes to oncological practice. Early guidance aimed to balance the risks of immunosuppression and the benefits of treatment against the risks of COVID-19 infection, as well considering the effects on resource prioritization. In the context of CRC, these guidelines aimed to prioritize adjuvant chemotherapy instead of palliative chemotherapy [29] . A significant increase in the use of short-course radiotherapy for rectal cancer was also observed during this period [34] . Our results demonstrate the importance that clinicians placed on key human factors, including communication, coordination and leadership, during the first wave of the pandemic [35] . Human factor principles can help us understand the interaction between humans and other elements of a system in order to improve safety, which is particularly important for a healthcare system under stress [36] . For example, communication during the COVID-19 pandemic may be negatively affected by the need to use PPE, workforce stress and fatigue, and unfamiliar working environments. We found that clinicians felt that a well-led and responsive organization is better able to plan the most appropriate response to these challenging circumstances. Provision of colorectal cancer services in mid-April by the availability of surgical 'cold sites' pandemic, it is vital that CRC services are protected and maintained in addition to tackling the existing shortfall in diagnostics and treatment from the first peak of the pandemic. The use of 'cold sites', particularly in regions with high rates of COVID-19, appears to be pivotal for both surgical and diagnostic capacity, and highlights the need for regional coordination and cooperation as well as the importance of human factors such as clear communication and strong leadership.
