RESUMO
PurposeSeveral studies have reported adopting prone positioning (PP) in non-intubated patients with COVID-19-related hypoxaemic respiratory failure. This systematic review and meta-analysis evaluated the impact of PP on oxygenation and clinical outcomes. MethodsWe searched PubMed, Embase and COVID-19 living systematic review from December1st 2019 to July23rd 2020. We included studies that reported using PP in hypoxaemic, non-intubated adult COVID-19 patients. Primary outcome measure was the weighted mean difference (MD) in oxygenation parameters (PaO2/FiO2, PaO2 or SpO2) pre and post-PP. ResultsFifteen single arm observational studies reporting PP in 449 patients were included. Substantial heterogeneity was noted in terms of, location within hospital where PP was instituted, respiratory supports, frequency and duration of PP. Significant improvement in oxygenation was reported post-PP: PaO2/FiO2, (MD 37.6, 95%CI 18.8, 56.5); PaO2, (MD 30.4 mmHg, 95%CI 10.9, 49.9); and SpO2, (MD 5.8%, 95%CI 3.7, 7.9). Patients with a pre-PP PaO2/FiO2 [≤]150 experienced greater oxygenation improvements compared with those with a pre-PP PaO2/FiO2 >150 (MD 40.5, 95%CI -3.5, 84.6) vs. 37, 95%CI 17.1, 56.9). Respiratory rate decreased post-PP (MD -2.9, 95%CI -5.4, -0.4). Overall intubation and mortality rates were 21% (90/426) and 26% (101/390) respectively. No major adverse events were reported. ConclusionsDespite significant variability in frequency and duration of PP and respiratory supports, PP was associated with improvements in oxygenation parameters without any reported serious adverse events. Major limitation being lack of control arm and adjustment for confounders. Clinical trials are required to determine the effect of awake PP on patient-centred outcomes. Systematic review registrationRegistration/protocol in PROSPERO (CRD42020194080). What is the key question?Is the novel approach of prone positioning in non-intubated patients associated with improvement in oxygenation? What is the bottom line?Prone position in non-intubated severe COIVD 19 suffers is associated with improvement of oxygenation while the short- and long-term patient centred out comes in this awake prone patient need more investigation. Why read on?Our study is first of its kind (Systematic review and Meta-analysis) summarising the evidence surrounding the less invasive innovate technique of prone position in non-intubated COVID-19 patients.
RESUMO
BackgroundClinical guidelines on infection prevention strategies in healthcare workers (HCWs) play an important role in protecting them during the SARS-CoV-2 pandemic. Poorly constructed guidelines that are not comprehensive and are ambiguous may compromise HCWs safety. We aimed to develop and validate a tool to appraise guidelines on infection prevention strategies in HCWs. MethodsA 3-stage, web-based, Delphi consensus-building process among a panel of diverse HCWs and healthcare managers was utilised. We validated the tool by appraising 40 international, specialty-specific and procedure-specific guidelines along with national guidelines from countries with a wide range of gross national income. ResultsOverall consensus ([≥]75%) was reached at the end of three rounds for all six domains included in the tool. The chosen domains allowed appraisal of guidelines in relation to general characteristics (domain-1), recommendations on engineering (domain-2) and administrative aspects (domain 4-6) of infection prevention, as well as personal protection equipment (PPE) use (domain-3). The appraisal tool performed well across all domains and inter-rater agreement was excellent. All included guidelines performed relatively better in domains 1-3 compared with domains 4-6 and this was more evident in guidelines originating from lower income countries. ConclusionThe guideline appraisal tool was robust and easy to use. Recommendations on engineering aspects of infection prevention, administrative measures that promote optimal PPE use and HCW wellbeing were generally lacking in assessed guidelines. This tool may enable health systems to adopt high quality HCW infection prevention guidelines during SARS-CoV-2 pandemic and may also provide a framework for future guideline development. FundingNo funding received. Key SummaryWe developed and validated a guideline-appraisal tool by appraising 40 different guidelines from countries with varying GNI. This tool may help healthcare systems to adopt high-quality HCW infection-prevention guidelines during COVID-19 pandemic and may also provide a guideline development framework.
RESUMO
ObjectivesTo evaluate PPE-preparedness across intensive care units (ICUs) in 6 Asia-Pacific countries. PPE-preparedness was defined as the adherence to guidelines, training HCWs, procuring PPE stocks and responding appropriately to a suspected case (transportation and admission to hospital). DesignCross-sectional web-based survey. SettingICUs in Australia, New Zealand (NZ), Singapore, Hong Kong (HK), India and Philippines with a 24/7 Emergency/Casualty Department, and capable of mechanically ventilating patients for >24 hours. InterventionsQuestionnaire sent to intensivists in 633 Level ll/lll ICUs in 6 Asia-Pacific countries by email, WhatsApp and text messaging. Main outcome measures263 intensivists responded, of whom 231 were eligible for analysis. Response rates were 68%-100% in all countries except India, where it was 24%. 97% either conformed to or exceeded WHO recommendations for PPE-practice. 59% employed airborne precautions irrespective of aerosol-generation-procedures. There were variations in negative-pressure room use (highest in HK/Singapore), training (best in NZ), and PPE stock-awareness (best in HK/Singapore/NZ). High-flow-nasal-oxygenation and non-invasive ventilation were not options in most HK (66.7%, 83.3% respectively) and Singapore ICUs (50%, 80% respectively), but were considered in other countries to a greater extent. 38% reported not having specialized airway teams. Showering and "buddy-systems" were underutilized. Clinical waste disposal training was suboptimal (38%). ConclusionsMost intensivists from six Asia-Pacific countries appeared to be aware of the WHO PPE-guidelines by either conforming to/exceeding the recommendations. Despite this, there were widespread variabilities across ICUs and countries in several domains, particularly related to PPE-training and preparedness. Standardising PPE guidelines may translate to better training, better compliance and policies that improve HCW safety. Adopting low-cost approaches such as buddy-systems should be encouraged. More importantly, better pandemic preparedness and building systems with deeply embedded culture of safety is essential to ensure the safety and well-being of HCWs during such pandemics.

C_LIO_LITo ensure the safety and well-being of HCWs, urgent measures are needed to improve PPE-preparedness and building systems with deeply embedded culture of safety. By helping ICUs evaluate and improve their current state of PPE preparedness, the study may help prevent healthcare worker infections and save lives. C_LI
