AIM: To identify, review and evaluate international proning and skin care guidelines and make an inventory of commonly used equipment and training resources. DESIGN: A gap analysis methodology was applied. METHODS: 1) Comprehensive search and evaluation of proning and skin care guidelines, 2) extensive search and listing equipment and educational resources, and 3) international consultation with 11 experts (8 countries). DATA SOURCES: A variety of sources researched through July 2021 were used to identify relevant literature: (1) scientific literature databases and clinical trials registries, (2) intensive care and wound care associations, (3) healthcare organisations, (4) guideline development organisations, and (5) the Google search engine. Eleven international experts reviewed the literature and provided insights in two, 2-h online sessions. FINDINGS: The search yielded 24 guidelines. One clinical practice guideline had high methodological quality. Twenty-five devices/equipment and sixteen teaching materials were identified and discussed with the expert panel. The gap analysis identified a lack of concise, accessible, evidence-based guidelines and educational materials of short duration. CONCLUSION: This analysis forms the basis for designing a competency-based education and training intervention for an interdisciplinary team caring for the skin of critically ill patients in the prone position. IMPACT: The results can assist the multidisciplinary team to review their current protocol for prone positioning. This is a first step in developing a training package for clinicians. The prone position, also referred to as 'ventral recumbent' [1] , has been utilized in patients with acute respiratory distress syndrome (ARDS) -an acute inflammatory lung injury [2] -since the late 1970s, when Piehl and Brown (1976) first published on its effectiveness [3] . The efficacy of prone ventilation is due in part to the reversal of atelectasis, increased homogeneous pulmonary aeration, alveolar recruitment, minimisation of ventilator-induced barotrauma, drainage of pulmonary secretionsall leading to improved gas exchange [4, 5] . The Proning Severe ARDS Patients (PROSEVA) multicentre randomised control trial [4] showed that early and prolonged prone positioning -more than 16 h/day -of the patient with severe ARDS also decreased their mortality at 28-days and 90-days. At 28-days the prone position group's mortality was 16% versus 32.8% in the supine position group, and at 90-days, the prone position group's mortality was significantly lower (P < 0.001) with 23.6% versus 41% in the supine group with a hazard ratio of 0.44 (95% CI, 0.29 to 0.67). A consequent systematic review and meta-analysis by Sud and colleagues [6] concluded from six trials (n = 1016) that when using lung protective ventilation in patients with moderate to severe ARDS, and early prone positioning, mortality significantly decreases (risk ratio 0.74, 95% CI 0.59 to 0.95; I 2 = 29%). The rapid spread of SARS-CoV-2, a novel coronavirus (COVID-19) [7] , has resulted in an increased number of patients presenting with typical ARDS-type pathological lung changes, prompting intensive care units to adopt prone positioning without necessarily having all the resources, staff and, protocols in place to guide management of the patient to preserve tissue viability. Not all patients with COVID-19 infections have severe symptoms; however, approximately 19% of the infected patients present with severe or critical symptoms according to a large descriptive, exploratory analysis of more than 72,000 patient records in China where the outbreak originated [8] . Most of these critically ill patients develop severe ARDS (67%), require mechanical ventilation (71%) and prolonged repositioning in the prone position (11.5%) [8] . Although prone ventilation is a lifesaving strategy, this postural therapy is not free from harm; adverse events such as endotracheal tube obstruction, unplanned extubations, tachy-and bradyarrythmias, loss of venous and arterial access, cardiac arrests, and pressure ulcer (PU) development [6] on the anterior body surface areas may ensue, with major airway complications and PUs the most prevalent [9] . Mora-Arteaga and colleagues [10] reviewed seven randomised trials (2119 patients) and found that PU development in prone position was the most frequently observed adverse event at 34% (OR: 2.19; 95% CI 1.55-3.09; p < 0.0001; I 2 0%). The 2017 meta-analyses and systematic review by Munshi and colleagues [11] , reviewing three studies [4, 12, 13] with a total of 1,109 participants concluded that prone position poses a higher risk for the development of PUs compared to the supine position (RR 1.22, 95% CI 1.06-1.41, I 2 0%). In prone position, there is an increased risk of developing a PU because the patient remains in this position for up to 16 h or longer (up to 24 h) without the ability to turn the patient sideways as easily as a patient in the supine position. More bony areas and thinner, soft tissue masses (e.g., at the forehead and chin) are exposed to the sustained weight of the body whilst in prone position versus lying dorsally [14] . In a 2021 study by Shearer et al. [15] of the 143 prone ventilated patients, 47.6% (n = 68) developed facial PUs with 84% (n = 57) on the cheeks and 50% on the ears. A recent study in a population of COVID-19 patients, reported 34.6% of the PUs being of the peri-oral area related to medical devices [16] . Much of the current biomechanical understanding concerning tissue loading conditions has been developed prior to the COVID-19 pandemic, in the context of prone surgeries such as spinal procedures. This published research has highlighted the unusual localised (focal) deformations and stress concentrations that form in soft tissue structures exposed to the bodyweight forces associated with prone positioning, which cannot be relieved during surgery, similarly to the critical care circumstances that apply during prone ventilation [17] . Like in the surgical arena, the life-support instrumentation may induce additional localised compressive, tensile and shear forces on the surface of the body. Other threats to skin integrity include moisture-associated skin damage (MASD) due to the increased drainage of respiratory secretions and skin tears due to mechanical trauma of positioning/repositioning of the patient. Adverse events increase when the complexity of care increases, as seen in the case of critical care units [18] . Pressure ulcers are adverse events that can lead to increased costs for treatment, length of hospitalisation, in addition to increasing emotional stress to the patient's family members in the intensive care unit [19] . Amidst the current pandemic, where there is a dramatic increased adoption of prone positioning with critically ill patients affected by severe COVID-19, it was timely and relevant to conduct a gap analysis to review and evaluate international proning and skin care guidelines which might assist the multidisciplinary team in the preservation of patients' skin integrity in the prone position, and to make an inventory of commonly used equipment and training resources. Secondly, to discuss the results of the review with the international expert panel to identify where gaps exist and the differences between the current situation and what should be in place. A gap analysis methodology was applied during this study. A gap analysis is a useful tool to examine the current state of a health care challenge (prone positioning) and identify areas where the existing reality is different from the ideal situation (guidelines/protocols) [20] . 1) Comprehensive search of international proning and skin care guidelines was done using electronic literature databases and clinical trials registries. Intensive care and wound care associations, healthcare organisations and guideline development organisations were searched using the Google browser. Those guidelines which could be evaluated by a validated tool, was appraised using the AGREEII instrument [21] . If equipment/devices (used for prone ventilated patients) or educational resources were found during the search, they were listed (Tables 3 and 4) . 2) An international expert panel was established in November 2020. The 11 experts from 8 countries reviewed the literature and provided insights in two, 2-h recorded online sessions. These electronic databases were searched up to July 2021 for relevant literature: Medline on the PubMed interface, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCO interface), Cochrane Database of Systematic reviews and The Cochrane Central Register of Controlled Trials. The clinical trials registry (www.clinicaltrials.gov) was searched to include prospective or ongoing studies. Grey literature using Open Grey (www.op engrey.eu) was searched and reference lists of included studies were scanned. All records with mechanically ventilated adults (>18 years old) in critical care units were included. 'Covid-19' or synonyms were not utilized as a keyword to include all ventilated adults regardless of respiratory disease/lung injury requiring prone positioning. Keywords for 'guideline' were not used to avoid missing any mentioned equipment, applicable to skin damage prevention. Studies were limited to English language and full text, but no limitation to year of publication. The concepts of "prone position" and "skin damage/pressure ulcer" and their synonyms were searched and then combined (example of search strategy in Supplement A).

Step-by-step procedure. Abbreviation: MeSH: medical subject heading. * = Truncation symbol, representing any character or no character. Fig. 1 outlines the screening process. After database searching and locating two additional records from the clinical trials registry, 208 records were included, and 147 records were available for screening after duplicates (n = 61) were removed. After assessing the title and abstracts, 80 records mentioning both "prone position" and "pressure ulcers/injuries" were included. Thirty-eight records were excluded due to mention of generic or product brand names but were used to complete the product inventory. After removing 24 records that did not refer to other guidelines or products, this resulted in seven (n = 7) records that contained guidelines/recommendations. Critical care and wound care associations, healthcare organisations and guideline development organisations were searched using the Google browser. These included the World Health Organisation (WHO), National Institute for Health and Care Excellence (NICE) and critical care societies but the focus was on wound care associations who are likely to publish guidance on skin/tissue damage prevention e.g., the European Pressure Ulcer Advisory Panel (EPUAP). If guidelines were identified, they were explored in detail, using their reference lists to establish if any protocols were available from other sources like universities or hospitals. Clinical practice guidelines (CPGs) were appraised by using the valid and reliable Appraisal of Guidelines for Research and Evaluation (AGREEII) instrument [21] . Two appraisers (AF and SS) individually evaluated the CPGs. Guidance documents e.g., recommendations/tips, which could not be assessed with an instrument, were evaluated by the expert panel. Internet searches were conducted using the Google® browser (July-November 2020) to find equipment/devices and teaching aids that clinicians can use either to assist with the prone manoeuvre, but more importantly aids to minimise skin damage -in preparation for the expert consultation (November 2020). Media searches included You-Tube® videos, industry websites and virtual conferences to broaden the search. The equipment was added to the inventory list and categorised according to their function e.g., dressings, prone positioning support, and traditional aids. It was beyond the scope of this article to evaluate the evidence for the effectiveness of products in preventing skin/tissue damage in the prone position. Educational resources were listed by duration of online content, conflict of interest, whether theoretical or a demonstration. Consultations with clinical-and academic experts in the field of critical care, prone positioning, pressure ulcers/injuries, skin integrity and biomechanical research were an integral part of this study. The experts were invited to be part of an 11-member international expert advisory panel. These members are experts in the field of nursing science, bioengineering aspects, critical care, and skin/wound care with the relevant medical/clinical and practical expertise. In addition, a wide geographical spread (eight countries): two experts were from the United States of America, three from Belgium, and one expert each were from Chile, Canada, Finland, Israel, Australia, and South Africa. The role of the expert panel was to review the search results and together with the research team, identify gaps and clinician needs. Two 2-h recorded online sessions were held (25/26 November 2020) to gain the experts' feedback/suggestions. A draft of the review, and gap analysis results were sent to the members one week prior to the online A. Fourie et al.

During the meeting, the following questions were asked: Questions to experts during feedback session 25th/26 th November 2020 1a) What are the key considerations before clinical guidance related to skin damage for the patients in the prone position are implemented in a clinical setting? 1b) What key descriptors should be present in a clinical guidance for prevention of skin damage for the patient in the prone position? 1c) What are the barriers to guideline implementation related to the prevention of skin damage in prone positioned patients? 1d) What is your perspective on how barriers to guideline implementation related to prevention of skin damage in prone positioned patients can be avoided? 2a, b) What comprises the ideal equipment/device to prevent skin damage for the patient in the prone position, and what is missing? 3a) What components/content should educational material related to prevention of skin damage for patients in the prone position consist of? 3b) How should educational resources related to prevention of skin damage for patients in the prone position be organised for successful conveyance to clinicians in critical care units? What future research is needed to assist clinicians to optimally care for the critically ill patient in the prone position to prevent skin damage? Further consultation via e-mail ensued between the research team and the experts after the meeting to ensure correct interpretation of their feedback, sharing of any extra materials the experts deemed fitenhancing the comprehensiveness of the study. All the relevant recorded or written comments were collated and incorporated into the final gap analysis and reviewed by the experts. The Ethics Committee of Ghent University confirmed that no ethical approval was needed for doing this gap analysis since only public available data were collected, without patient involvement. A total of 24 guideline documents were identified: seven from the literature search (Table 1 ) and 17 from organisations ( Table 2 ). The most recent (through July 2021) literature search identified seven guidelines/recommendations that address prevention of patient skin/ tissue damage in the prone position. Authors described either best • The expert panel agreed that amongst a crisis like COVID-19, there is no time for the clinicians to search the plethora of resources, evaluate the evidence and then teach and implement it. The resources are varied in duration from less than 2 min up to 1 h, with some showing hands-on prone manoeuvring, or others focusing on theory. A. Fourie et al. practises, implementation strategies, protocols, clinical guidelines, checklists, or educational programmes. Not all resources, such as protocols or videos, were available as a hyperlink, via reference, or in supplemental documentation (Table 1) . Eleven (n = 11) articles referenced other organisations such as the Faculty of intensive care medicine & Intensive Care Society (FICM & ICS) [22] . During the internet search, 21 organisations were searched and 17 published guidance documents/materials, were identified. The WHO did not publish guidance, however NICE referred to the FICM & ICS 2019 guideline and the Tissue Viability Society's website provided a reference site to guidelines from other organisations or industry ( Table 2) . One CPG was found regarding PU prevention, with a specific chapter on prone positioningfrom the European Pressure Ulcer Advisory Panel/National Pressure Injury Advisory Panel and the Pan Pacific Pressure Injury Alliance (EPUAP/NPIAP/PPPIA) [30] . This CPG was of high methodological quality and clinical content according to the AGREEII appraisal instrument. The two appraisers reached a 94% consensus, scoring half of the domains e.g., scope and purpose, clarity of presentation and applicability of the CPG as 'strongly agree' per each item. Since the guidance documents are not all CPGs and cannot be appraised with a validated tool, the expert panellists' perspectives and opinions regarding the guidance documents' key considerations, key descriptors and barriers to implementation were instrumental in identifying gaps. • The expert panel mentioned that guidance documents should address the aetiology of tissue damage in the prone position vs. the dorsal position, why certain recommendations for tissue protection is recommended (the rationale) yet keep guidance documents simple and easily accessible. Guidance documents should be based on evidence and speak to the specific audience. Before implementation, all stakeholders should be involved to gain insight from a multidisciplinary team to get commitment for driving the successful implementation. A bundled approach is necessary to address not only PUs but include preventative strategies for MASD, skin tears and incontinence-associated dermatitis. Thirty-eight records (n = 38) emerged from the literature review that did not include guidance documents but did mention devices/devices used in clinical practice to help prevent pressure ulcers or MASD (Table 3) . Generic product suggestions were mentioned in 18 records and products with brand names in 20 records. Twenty-five product names were listed. Surgical products were not listed (exclusion criterion) unless a surgical product was used in a critical care setting, as described by Capasso and colleagues [31] . • The experts noted that few of the equipment/devices were designed for use in prone position to specifically avoid skin damage. Dressings for example have been designed for wound healing/treatment and have not been extensively studied for the prevention of skin/tissue damage in prone position. A recent biomechanical study did however indicate a reduction of soft tissue stress exposure on the forehead (52%) and chin (78%) when multilayered foam dressings are applied prophylactically in the prone position [32] . Resources were found in the form of YouTube® video recordings showing the prone positioning manoeuvre, webinar educational sessions, blogs, company product training videos etc. Sixteen digital resources were identified (Table 4 ) during the search, up until November 2020. Five of the resources (31.3%) showed practical hands-on training of the prone positioning manoeuvre or equipment use, and 31.3% were of duration less than 10 min. Of note is the HAPI-less project/video series (hospital-acquired pressure injuries) which gives theoretical tips on PU reduction strategies (Mobility is Medicine, 2020) [34] . The Rush University Medical Center [35] developed a four-phased checklist and during their recording showed the practical hands-on prone manoeuvre and how to use the checklist from preparing to management of the patient. The main aim of this study was to perform a gap analysis of the current state of guideline documents or recommendations and to explore, through expert consultation, what is needed for clinicians to help prevent skin/tissue damage in patients in the prone position. The guidance documents vary from a high methodological quality CPG [30] for purchase, to recommendations and useful practical tips for patient management strategies (Tables 1 and 2 ). Institutions/hospitals base their prone positioning protocol on different guidance documents or create their own protocol according to accessible resources, staff competence and availability. The guidance documents of institutions/hospitals are not always publicly available due to internal privacy/sharing policies. The analysis revealed that there is a lack of an open-access, holistic, yet simple evidence-based guidance document, written after seeking consultation and buy-in from stakeholders in the multidisciplinary team. The stakeholders should include clinical nurses, medical doctors, other health care team members, former patients, and policy makers. Perceived complexity should be avoided by not using foreign abbreviations or referral to unknown device categories which might be unavailable. An explanation of the principles/rationale of a recommended strategy, or what not to dobased on clinical evidenceshould rather be employed to decrease barriers to implementation. Secondarily, the aim was to see what is available (devices and educational resources) and what the experts suggest in relation to the current list (Tables 3 and 4) . Even though some of the products are widely used in clinical practice, there is a lack of non-industry sponsored, high-level evidence specifically for patients in the prone position. This provides an opportunity for further research, both for robust clinical trials with a pragmatic design and computer modeling to analyse skin and subdermal tissue loading conditions with and without specific devices. The evidence for the efficacy of prone products has not been evaluated and this may be of interest for a future systematic review. During a crisis like COVID-19, there is a lack of time and staff resources to refer to long didactic or online educational sessions. There is a need for short 5-min videos to practically show different aspects of patient management e.g., how to secure the endotracheal tubes in the prone position, how to perform pressure relieve/micro-shifts etc. It is imperative to first conduct a skin and wound management competencybased training needs assessment before any educational strategy can be designed/recommended. A training needs assessment can identify competency gaps [36] related to this topic and guide impactful and fit-for-purpose skills development for clinicians. Limitations to this study are the dynamic nature of an internet search with new information posted per second and therefore the search had to be limited to a specific period. Hospitals predominantly post their protocols/guidelines on their intranet, not available to public searches and therefore a vast number of guidance documents are not available for review/utilization. The strength of this study was the comprehensive literature search which was recently repeated (July 2021) to include the latest publications. Of note was the increased publications since the previous search ending November 2020 on this topic -which is directly linked to the second surge of the COVID-19 pandemic and the clinical and academic need related to patient management strategies. A second strength is the congregation of insights from experts across Europe, Americas, Africa, and Australia into the diverse clinical practices from their different countries and current research being conducted related to this topic. This gap analysis, including a comprehensive search and expert consultation, provides the basis for the design of a competency-based education and training intervention for an interdisciplinary team of clinicians caring for the skin of ICU patients in the prone position.
