Background Whereas 5,415 Intensive Care Unit (ICU) beds were initially available, 7,148 COVID-19 patients were hospitalised in the ICU at the peak of the outbreak. The present study reports how the French Health Care system created temporary ICU beds to avoid being overwhelmed. Methods All French ICUs were contacted for answering a questionnaire focusing on the available beds and health care providers before and during the outbreak. Results From 336 institutions with ICUs before the outbreak, 315 (94%) participated, covering 5,054/5,531 (91%) ICU beds. During the outbreak, 4,806 new ICU beds (+95% increase) were created from Acute Care Unit (ACU, 2,283), Post Anaesthetic Care Unit and Operating Theatre (PACU & OT, 1,522), other units (374) or real build-up of new ICU beds (627), respectively. At the peak of the outbreak, 9,860, 1,982 and 3,089 ICU, ACU and PACU beds were made available. Before the outbreak, 3,548 physicians (2,224 critical care anaesthesiologists, 898 intensivists and 275 from other specialties, 151 paediatrics), 1,785 residents, 11,023 nurses and 6,763 nursing auxiliaries worked in established ICUs. During the outbreak, 2,524 physicians, 715 residents, 7,722 nurses and 3,043 nursing auxiliaries supplemented the usual staff in all ICUs. A total number of 3,212 new ventilators were added to the 5,997 initially available in ICU. Conclusion During the COVID-19 outbreak, the French Health Care system created 4,806 ICU beds (+ 95% increase from baseline), essentially by transforming beds from ACUs and PACUs. Collaboration between intensivists, critical care anaesthesiologists, emergency physicians as well as the mobilisation of nursing staff were primordial in this context.

At the peak of the outbreak, 9,860, 1,982 and 3,089 ICU, ACU and PACU beds were made available.

Before the outbreak, 3,548 physicians (2,224 critical care anaesthesiologists, 898 intensivists and 275 from other specialties, 151 paediatrics), 1,785 residents, 11,023 nurses and 6,763 nursing auxiliaries worked in established ICUs.

A total number of 3,212 new ventilators were added to the 5,997 initially available in ICU.

During the COVID-19 outbreak, the French Health Care system created 4,806 ICU beds (+ 95% increase from baseline), essentially by transforming beds from ACUs and PACUs. Collaboration between intensivists, critical care anaesthesiologists, emergency physicians as well as the mobilisation of nursing staff were primordial in this context.

The COVID-19 caused a worldwide outbreak of respiratory illnesses that quickly invaded the world (1, 2) . Its most severe form causes an acute respiratory distress syndrome (ARDS) requiring mechanical ventilation and thus Intensive Care Unit (ICU) admission. World Health Organization recommendations tried to prevent cross-contamination in order to flatten the curve of the disease, reduce morbidity and mortality and prevent situations in which the capacity of various healthcare systems would be exceeded (3).

After China, COVID-19 quickly spread to Europe, first to Italy, then Spain and France. In France, the first cases were diagnosed on the 24 th of January 2020 and the outbreak quickly spread throughout the north-eastern part of the country, rapidly overwhelming their ICU capacity (4).

For the first time, the French government decided to apply the national plan for healthcare institutions (named "Plan Blanc"), postponing all scheduled non-urgent surgical and medical procedures. A complete nation-wide lockdown was also decided on the 17 th of March 2020 (5).

To prevent ICUs from being overwhelmed, national and regional healthcare institutions (the French Health Ministry and all Regional Health Agencies) decided to increase the availability of ICU beds by creating new temporary ICU beds in institutions that may or may not have had an ICU prior to the outbreak. The availability of ICU beds was assessed daily in each institution and at the regional level to organise, if necessary, potential patient transfers between regional and national hospitals (6) (7) (8) . The unprecedented overall mobilisation and joint efforts of various medical, paramedical and administrative staffs enabled caregivers to manage the most serious cases in each ICU (9) . Following the example of Bergamo hospital in Italy, all physicians who could manage ICU patients were involved in dealing with the crisis (10, 11) . French anaesthesiologists (with a minimum of two years' ICU training during their curriculum) were also involved, since surgical activities were reduced to emergencies and procedures difficult to postpone (such as J o u r n a l P r e -p r o o f cancer) (6, 11) . On the 8 th of April, thanks to this overall organisation, 7,148 patients were hospitalised in ICU beds, whereas the official national capacity before COVID-19 outbreak was only 5,432 ICU beds (12,13).

The present study therefore describes how new ICU beds were created in France to receive the first wave of the most severely ill COVID-19 patients and what type of healthcare professionals were mobilised to care for these patients. This retrospective multicentric observational study was approved by the Institutional Review Board of the French Society of Anaesthesia and Critical Care (CERAR# 00010254-2020-094, May 6, 2020) and registered on Clinical Trials (NCT04420286) (14) . STROBE recommendations for observational studies were followed (15) .

Three types of units for managing the most seriously ill patients can be distinguished: i) Intensive

Care Units (ICU) are dedicated to patients with (or at risk of) at least two organ failures; ii) Continuous Care Units (CCU) for patients with only one organ failure specific to a particular medical specialty (cardiology, neurology, nephrology…); iii) Acute Care Units (ACU) dedicated to patients at risk of developing an organ failure in postoperative or medical settings. In December 2018, the number of available ICU beds was 5,432 among 325 healthcare facilities (ICU beds from military hospitals and oversea territories hospital (Polynésie Française and Nouvelle Calédonie) were not included in this evaluation) (13).

Physicians working in ICUs may be primarily trained in anaesthesiology or intensive care medicine. Any anaesthesiologist can work in an ICU as a "critical care anaesthesiologist" or in procedural area as anaesthesiologist. These two professions are interchangeable throughout their career.

There is no mandatory bed-to-physician ratio but during the day, about 4 full-time physicians are required for 10 ICU beds and 2 for 10 ACU beds (16) . For nurses, a ratio of 2 ICU nurses for 5 patients and 1 nursing auxiliary for 4 patients is a legal requirement in the ICU.

From the 2 nd of May to the 12 th of June 2020, all French ICU managers (both physicians and nurses) were contacted by e-mail or phone to participate in the study. Agreement to respond was considered as consent to participate. outbreak. Likewise, the number of ACU beds created from PACU or OT, other units or newly constructed was recorded. We also recorded the number of beds transformed from specialised surgical ICUs to classical ICUs (not considered as newly created ICU beds).

Section 3 focused on the number of new staff members (physicians, nurses and nursing auxiliaries) allocated to the ICU during the COVID-19 outbreak. The new dedicated intensivists, anaesthesiologists (used to working in OT), residents, fellows, nurses, operating theatre nurses, anaesthetic nurses and nursing auxiliaries involved in daily management were recorded.

The number of new ventilators used at these ICUs was also recorded in this section.

The primary objective was to describe the number of new temporary ICU beds and their origin (ACU, PACU or OT, other unit, real creation) during the COVID-19 outbreak in France.

The secondary objective was to describe the human resources mobilised to cope with the surge in acute care patients.

Data were processed using the open-source REDCap Data Management Platform hosted by Nîmes University Hospital (17) . Quantitative variables are expressed in medians and ranges.

Qualitative data are expressed in absolute numbers with percentages. As this was a strict observational study, no comparison was performed.

J o u r n a l P r e -p r o o f RESULTS:

From 336 institutions with an ICU (5,531 ICU beds) before the outbreak, 315 participated (response rate: 94%), representing 5,054 ICU beds (91%) (figure 1). In these institutions, there were 3,339 ACU and 4,920 PACU beds (figure 2).

During the outbreak 4,806 new ICU beds (+95% increase) were created. Among them, 399 ICU beds were created in 43 institutions newly authorised to have an ICU. Figure 2 displays the timing of this increase according to the origins of 4,806 new ICU beds (3.805 (79%) from ACUs (2283) and PACUs (1522)). At the peak of the outbreak on the 8 th of April, 9,860 (+95%), 1,982 (-41%) and 3,089 (-37%) ICU, ACU and PACU beds were available, respectively, representing a total of 14,931 (+12%) beds available for the most severely ill patients. Based on the answers obtained from 315/336 institutions (94%) with ICU, our study shows that these facilities were able to increase their ICU capacity from 5,054 ICU beds available before outbreak to a total of 9,860 beds at the peak of the outcome. The French Health Care System was able to create 4,806 additional temporary ICU beds by upgrading ACU (n = 2,283), PACU, OT (n = Over the last two decades, the risk of overwhelming of the ICU capacity was mainly described during terror attacks such as the New-York, Madrid, London, Paris and Nice attacks (18) (19) (20) (21) (22) . Such events required a prompt evaluation of bed availability for the most severely injured patients.

Regarding human resources, all available caregivers were called in to readily support the inhouse staff. The collaboration between emergency physicians, critical care anaesthesiologists, anaesthesiologists, intensivists, surgeons and radiologists was crucial to optimise patient care.

Paris and Nice attacks occurred at night and, the presence of non-used hospital beds at that time of the day greatly facilitated patient management (21, 22) . In contrast to terror attacks, the COVID-19 pandemic has generated unprecedented requirements in additional ICU beds for more than two months. Hence, during the COVID-19 outbreak, the intent of postponing all elective procedures and of activating the national surge plan "Plan Blanc" was to obtain a long-lasting increase of the total number of hospital beds available.

During the COVID-19 outbreak, few studies have reported on how the various healthcare systems adapted. Bergamo hospital reported that new beds (adult, paediatric, surgical) had to be made quickly available together with the creation of short educational program for non-critical care trained caregivers (10) . At New York's Presbyterian Weill Cornell Medical Center, ICU beds were created from beds available in OTs and PACUs that were not being used, as all elective procedures were cancelled (22) . In Boston, Massachusetts General Hospital transformed a 14-bed paediatric ICU into an adult ICU for one month so that 25 patients could be admitted, most of whom suffering from COVID-19 (23) . However, all these adaptations were achieved at a single centre representing 90 patients maximum. The present study is the first to report the response to the pandemic at the level of a national healthcare system. To date, only simulations and recommendations have been published (25, 26) .

The collaboration at all levels of the French healthcare system was crucial. At institutional level, the postponement of all elective procedures helped reallocate medical and paramedical staff to staff all the units involved in the care of the most severely ill COVID-19 and non-COVID-19 patients. In the second half of March, some paediatric beds from specialised surgical ICUs, ACUs and PACUs were quickly transformed, leading to a 95% increase in ICU bed capacity. In this context, after a dedicated training program, all non-used staff could be involved in ICU patient care, and anaesthesiologists with ICU training and anaesthetic nurses were first recruited to help manage these temporary ICU beds.

At national level, several daily meetings between the director of the regional healthcare agency Key lessons can be drawn from this outbreak on a national scale. ICU bed capacity can be rapidly and dramatically increased in the event of a national pandemic crisis. A 95% increase in ICU beds was observed even though the number of ACU and PACU beds had decreased (-41 and -37%, respectively). This organisation model allowed to preventing overwhelming of the 5,531 ICU beds initially available before the outbreak.

Collaboration between all specialties involved in the management of the most serious cases (intensivists, critical care anaesthesiologists, anaesthesiologists, emergency physicians) clearly strengthens the capacity to respond to the need to increase ICU capacity. Overlapping skills between different medical specialties was probably a positive element in the response to the outbreak. Also, this rapid adaptation of the healthcare system would not have been possible without a strong collaboration between all administrative and medical staffs at institutional, regional and national levels.

In the event of a similar crisis, a particular concern could arise from the availability of ventilators.

Indeed, our study shows that it was more complicated to increase their number than the number of ICU beds. This finding is in line with other shortages reported during the outbreak.

The present study has certain limitations. First, we were unable to contact every unit, but the national response rate > 90% of ICU beds initially available would probably allow us to draw certain conclusions and lessons for the future. Secondly, this organisation focused on ICU-bed capacity and human resources in terms of caregivers. Unfortunately, this did not prevent certain shortages of anaesthetic supplies and personal protective equipment. Thirdly, such arrangements are probably easier in small countries with high population densities where cities are close to each other (26, 28) . Indeed, in France, patient transfers could be organised from one region to another J o u r n a l P r e -p r o o f or to foreign countries less than 1000 km away. In bigger countries (USA, Canada, Russia and Australia) a different kind of organisation may be more appropriate. Lastly, the present study did not aim at analysing the impact of such organisation on patient outcome, especially mortality rate. On the 12 th of May, a partial evaluation of Santé Publique France agency reported 546 deaths over 2,307 ICU admitted patients with a complete follow-up (24%) between the 16 th of March and the 10 th of May (29). Docherty et al. (30) reported 26% mortality among 20,133 patients with COVID-19 patients admitted in 208 acute care hospitals in England, Wales and Scotland between the 6 th of February and the 19 th of April 2020. The mortality rates for patients admitted to ICUs and mechanically ventilated patients were 32% and 37%, respectively. In Italy, a recent study reported a 26% ICU mortality rate (31) . The number of deaths reported per million inhabitants is 455 for France, 573 for Italy, 606 for Spain and 632 for the UK (32).

In conclusion, the present study reports on the French healthcare system's response to the COVID-19 outbreak. Using ACU and PACU beds allowed us to double the number of ICU beds available in less than two weeks. Collaboration between intensivists, critical care anaesthesiologists, anaesthesiologists, emergency physicians as well as the mobilisation of nursing staff were primordial in this context.

This retrospective multicentric observational study was approved by the Institutional Review Board of the French Society of Anesthesia and Critical Care (CERAR# 00010254-2020-094, May 6 th 2020) and registered on Clinical Trials (NCT04420286).
