All adult trauma care has been centralised to the Royal Shrewsbury Hospital for assessment and medical input, before transferring those requiring operative intervention to the Robert Jones and Agnes Hunt Orthopaedic Hospital. We aim to review the impact of COVID-19 on hip fracture workload and service changes upon management of hip fractures. METHODS: We reviewed our prospectively maintained trust database and National Hip Fracture Database records for the months of March and April between the years 2016 and 2020. Our assessment included fracture pattern (intrascapular vs extracapsular hip fracture), treatment intervention, length of stay and mortality. RESULTS: We treated 288 patients during March and April between 2016 and 2020, with a breakdown of 55, 58, 53, 68, and 54 from 2016 to 2020 respectively. Fracture pattern distribution in the pre-COVID-19 years of 2016 to 2019 was 58% intracapsular and 42% extracapsular. In 2020 (COVID-19 period) the fracture patterns were 65% intracapsular and 35% extracapsular. Our mean length of stay was 13.1 days (SD 8.2) between 2016 to 2019, and 5.0 days (6.3) days in 2020 (p < 0.001). Between 2016 and 2019 we had three deaths in hip fracture patients, and one death in 2020. Hemiarthroplasty and dynamic hip screw fixation have been the mainstay of operative intervention across the five years and this has continued in the COVID-19 period. We have experienced a rise in conservatively managed patients; ten in 2020 compared to 14 over the previous four years. CONCLUSION: There has not been a reduction in the number of hip fractures during COVID-19 period compared to the same time period over previous years. In our experience, there has been an increase in conservative treatment and decreased length of stay during the COVID -19 period. Cite this article: Bone Joint Open 2020;1-8:500–507. The COVID-19 pandemic has placed immense pressure upon the National Health Service (NHS) as well as the general public. National Health Service England (NHSE) guidance in this COVID-19 period (1 March 2020 to 30 April 2020) suggests that there may be a role for nonoperative management of some fragility fractures; however, hip fractures will continue to be one of the most common operations and social isolation policy is unlikely to prevent this injury. 1 The proposed benefits of nonoperative care for fragility fractures include reduction of inpatient stay and associated risk of exposure to COVID-19, as well as resource allocation to manage the pandemic. 1 Within England, Wales, and Northern Ireland, 175 trauma units have provided care to 66,313 hip fractures patients in 2018. 2 The National Hip Fracture Database (NHFD) was established in 2007 as the result of a collaboration between the British Orthopaedic Association (BOA) and the British Geriatrics Society. This has led to a reduction in mortality with 6.1% of patients dying within 30 days of hip fracture in 2018. 2 Hip fractures remain a surgical priority during COVID-19 as reiterated by both the BOA and Royal College of Surgeons coronavirus guidelines. 3, 4 In order to sustain hip fracture services, initial management was centralised through the Royal Shrewsbury Hospital (RSH) for preoperative orthopaedic assessment and medical optimisation. Medically stable patients were then transferred to Robert Jones and Agnes Hunt Orthopaedic Hospital (RJAH) for operative intervention. We aim to review the impact of COVID-19 on workload and the related service changes on the management of hip fractures attending our orthopaedic service within rural Shropshire. We collected data from a prospectively maintained database, reviewing all hip fracture patients who attended the hospital during 1 March and 30 April between 2016 and 2020. Data parameters included: baseline demographics of age and sex, fracture type, treatment intervention, length of inpatient stay, and mortality. We also crosschecked the data with hospital clinical electronic records and the National Hip Fracture Database. The hip fracture pattern was categorized as intracapsular or extracapsular. Treatment was classified as: conservative (nonoperative), dynamic hip screw (DHS), hemiarthroplasty, total hip arthroplasty (THA), cannulated screw fixation or intramedullary nailing. For the purposes of discussion and comparison we have categorized the months of March and April 2020 as the COVID-19 period, in keeping with the changes to healthcare services during these months. In order to address the logistical challenges of the pandemic, all adult trauma, including hip fractures, from the region were diverted to the RSH for emergency care, medical optimization, and definitive orthopaedic surgical assessment. Orthopaedic surgical services were redirected to the regional specialist centre, RJAH. Medical admission in RSH was used as proxy for orthogeriatric review prior to surgical management for unstable patients, as there are care benefits including reduced mortality with this co-management model. 5 Transfer was facilitated 24 hours a day to allow prompt access to a trauma multidisciplinary team for a definitive treatment plan and timely operative intervention. Care has remained consistent with pre-COVID-19 pandemic, where hip fracture patients are managed as per National Hip Fracture Guidelines, 6 with the input of both trauma orthopaedic surgeons and orthogeriatric physician care. All patients received baseline preoperative investigations of the relevant pelvic and hip radiographs, plain chest radiographs, electrocardiogram, COVID-19 swabs and bloods tests. Patients were then transferred to RJAH once assessed as medically stable and suitable for operative intervention. RJAH has adapted to deliver care for trauma patients during COVID-19 pandemic including the cessation of elective operating, similar to other orthopaedic centres in order to help resource management and continued emergency care. [7] [8] [9] [10] The clinical environments were categorized as green (low-risk for COVID-19) and a blue (high-risk COVID-19) areas, similar to the proposed pathways described by the BOA for recommencement of non-urgent care. 11 Patients received a risk assessment for COVID-19 exposure in RSH, based on a simple risk of exposure questionnaire such that high risk or positive patients who remained medically stable were managed in a separate blue ward within RJAH. The RSH orthogeriatric consultants were also redeployed to RJAH in order to care for the patients who were transferred. Descriptive statistics were used to present means, SD, and ranges. Chi-squared tests ere used for categorical data and independent-samples t-test for continuous data, with significance set at p < 0.05. Statistical analysis of results was conducted using RStudio Team 2020 (Boston, Massachusetts, USA), and tables and figures produced on Excel (Microsoft, Redmond, Washington, USA). We treated 288 patients in the months of March and April during the years of 2016 to 2020 ( Figure 1 ). Of these patients, 181 were female and 107 were male, with a mean age of 82.6 (40 to 98). We found that over the five years there were a greater proportion of intracapsular (58%, n = 173) compared to extracapsular hip fractures (42%, n = 115) at our trust (Table I) . Between 2016 and 2019 mean length of stay was 13.1 days (SD 8.2). During the COVID-19 period the mean length of stay was 5.0 (SD 6.3). There was one COVID-19 related death due to respiratory infection (COVID-19 positive) who was palliated under the care of physicians. In the four years prior to COVID-19 there were three mortalities in hip fracture patients as a result of: hepatic failure secondary to alcohol excess and variceal bleed; end stage renal failure on background of previous renal hydronephrosis; and infective exacerbation of chronic obstructive pulmonary disease. Patients unsuitable for surgical intervention were treated conservatively. This decision was made following physician assessment in RSH and discussion with the RJAH trauma orthogeriatric team. There were ten patients managed conservatively during COVID-19 due to unstable medical conditions and patient choice (Table II) . Hemiarthroplasty and DHS have taken precedence in the management of hip fractures within our trust, especially in the pre-COVID-19 years (Figure 2 ). This has continued during the COVID-19 period, although there has been an evident rise in the number of patients who have been managed conservatively and limited undertaking of intramedullary fixation (Figure 3 ). Across the range of operative interventions for hip fractures, we have not found a statistically significant change to management (Table III) . There was limited undertaking of intramedullary nailing or cannulated screws during COVID-19, although these are few throughout our fiveyear experience compared to hemiarthroplasty and DHS. The COVID-19 global pandemic caused by the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) has taken an immense toll on the NHS. With over 44,000 deaths COVID-19 deaths, the United Kingdom has been one of the worst affected nations in the world. 12 The impact has necessitated large scale redesign of healthcare services, with new COVID-19 period guidelines across specialities. 13 In our region the trauma and orthopaedic surgery services have needed to adapt with the combined efforts of the RSH and RJAH. Elective operating has been stopped in keeping with national guidance for prioritisation. 4 In our experience, the number of patients attending with hip fractures has not decreased during COVID-19 despite government-introduced shielding and social distancing. 14 Indeed, the challenges of timely access to regular carers, community support from friends and family may have proven detrimental to patients suffering hip fractures. We cannot infer causation, although the challenges to both assessment and the provision of care during COVID-19 are highlighted by the CarersUK reports. 15, 16 We did not find a statistical significance difference between the ages of the two patient groups, however the age range during COVID-19 has been higher with the youngest patient being 62 years compared to 40 years in the pre-COVID period (Table I) . Lockdown and travel restrictions may affect young patients more as they sustain hip fractures following high energy trauma such as road traffic accidents, whereas the older population more commonly experience low-energy mechanism such as fall and fragility fractures. [17] [18] [19] United Kingdom 2011 National Census data also shows that Shropshire has a higher than average population over the age of 65, and so travel lockdown measures are unlikely to alter this population's activity. 20 BOA guidance has supported the selection of hemiarthroplasty in place of THA so as to prevent delay and deliver timely surgery for hip fracture during COVID-19. 3 In our pre-COVID-19 experience, hemiarthroplasty was the most common procedure followed by DHS which is consistent with NHFD 2019 report. 2 The accepted practice as per the National Institute for Health and Care Excellence (NICE) is to provide either hemiarthroplasty or THA for intracapsular fractures as per eligibility criteria. 6 Pre-COVID-19, the NHFD 2019 report shows 33.4% of eligible displaced intracapsular fractures were treated with THR nationally. 21 Pre-COVID-19, RJAH has delivered elective care and as such we cannot compare it to the current trauma hip fracture management in this hospital. Within our experience and with the presence of readily available specialist orthopaedic workforce at RJAH, we have not seen derogation from THA to hemiarthroplasty during COVID-19, as two cases were performed in this time (Table III) . At present we do not have a comparative literature to show if other units are undertaking hemiarthroplasties during COVID-19 for those who may have otherwise qualified for a THA pre-COVID- 19 . There has been a statistically significant threefold increase in conservative treatment during the COVID-19 period compared to pre-COVID-19 in our hospital (Table III) . A Cochrane systematic review that included five studies and 428 patients demonstrated that surgical management of undisplaced intracapsular fractures and undisplaced extracapsular hip fractures have better outcomes in terms of reduced length of stay and retaining patient independence, however there was limited evidence to inform practice. 22 A meta-analysis of 1,189 patients also found that there were only a few small studies comparing nonoperative and operative management of hip fractures, and nonoperatively treated hip fractures had a significantly higher 30-day and one-year mortaility. 23 We found one inpatient mortality in our COVID-19 period group, who was managed conservatively as a result of severe respiratory infection. This increase in conservative management may be due to a worsening of chronic medical comorbidities, which included a number of patients who presented with unstable cardiac pathology that required intensive medical input (Table II) . These patients are also the population at risk from COVID-19 and were advised to shield. Literature also corroborates the finding of comorbidity deterioration within the context of natural disasters. The University of Oxford Centre for Evidence-Based Medicine have summarized the issues of suboptimal management of chronic conditions during national emergencies, where elderly patients are particularly at an increased risk of morbidity and mortality. [24] [25] [26] [27] This is a particularly vulnerable group whose health is less amenable to tolerate significant adjustments to regular monitoring. In addition, the strain on medical specialities in managing with organisational restructuring and redeployment of workforce may have also led to challenges in optimisation of potential operative candidates during the COVID-19 period It is also clear that physicians have faced increased stress and sleep disturbance during the COVID-19 pandemic. 28, 29 We reiterate that these are possibilities, not criticisms of the efforts of medical and care workforces during the pandemic. Length of stay has decreased significantly in the COVID-19 period when compared to pre-COVID-19. This considerable decrease is partly as a result of efforts to expedite discharge in order to minimize patient exposure to COVID-19 within hospitals, and thereby increase capacity for hospital beds. RJAH established an enhanced arrangement with social services to facilitate more efficient discharge into the community during the COVID-19 pandemic, an example of the wider health and social care response to COVID-19. The Chancellor of the Exchequer announced plans for an enhanced NHS discharge process in March and supported this with a £2.9 billion fund. 30 This push for hospital capacity was also directed by government and NHS initiative through Strategic Coordination Groups, with the aim to "create and maintain acute bed capacity through faster rates of appropriate discharge from NHS beds for the foreseeable future". 31 The considerable changes to organisational pathways and an ever-evolving practice during the COVID-19 period, along with regular amendments to public care policy, mean that this is a snapshot of care during the current pandemic. Further studies may explore the role of chronic comorbidities in the management of hip fracture patients during COVID-19 and whether we should expect a more unwell population in future, which may further drive nonoperative care or necessitate more intensive pre and postoperative optimisation. The COVID-19 pandemic has forced significant changes to healthcare practice, affecting all specialities. Hip fracture care remains an orthopaedic priority and, in our experience, we have restructured services to an orthopaedic specialist hospital to continue delivering care for these patients. Effective multidisciplinary collaboration with medical and orthogeriatric specialities is required in the management of hip fractures and we recognise the increased strain on these allied specialities from the direct management of COVID-19 patients. There has not been a clear reduction in number of hip fractures during COVID-19 lockdown period compared to same time period over previous years. In our experience, there has been a significant increase in conservative management of hip fractures, with patients being more medically unstable at presentation with deterioration of chronic health conditions. This population were observing measures of social restrictions and shielding during COVID-19 period. We have also seen a significant decrease in length of stay compared to pre-COVID-19. Follow M. S.
