RESUMO
BACKGROUND: There is conflicting evidence on association between quick sequential organ failure assessment (qSOFA) and sepsis mortality in ICU patients. The primary aim of this study was to determine the association between qSOFA and 28-day mortality in ICU patients admitted for sepsis. Association of qSOFA with early (3-day), medium (28-day), late (90-day) mortality was assessed in low and lower middle income (LLMIC), upper middle income (UMIC) and high income (HIC) countries/regions. METHODS: This was a secondary analysis of the MOSAICS II study, an international prospective observational study on sepsis epidemiology in Asian ICUs. Associations between qSOFA at ICU admission and mortality were separately assessed in LLMIC, UMIC and HIC countries/regions. Modified Poisson regression was used to determine the adjusted relative risk (RR) of qSOFA score on mortality at 28 days with adjustments for confounders identified in the MOSAICS II study. RESULTS: Among the MOSAICS II study cohort of 4980 patients, 4826 patients from 343 ICUs and 22 countries were included in this secondary analysis. Higher qSOFA was associated with increasing 28-day mortality, but this was only observed in LLMIC (p < 0.001) and UMIC (p < 0.001) and not HIC (p = 0.220) countries/regions. Similarly, higher 90-day mortality was associated with increased qSOFA in LLMIC (p < 0.001) and UMIC (p < 0.001) only. In contrast, higher 3-day mortality with increasing qSOFA score was observed across all income countries/regions (p < 0.001). Multivariate analysis showed that qSOFA remained associated with 28-day mortality (adjusted RR 1.09 (1.00-1.18), p = 0.038) even after adjustments for covariates including APACHE II, SOFA, income country/region and administration of antibiotics within 3 h. CONCLUSIONS: qSOFA was independently associated with 28-day mortality in ICU patients admitted for sepsis. In LLMIC and UMIC countries/regions, qSOFA was associated with early to late mortality but only early mortality in HIC countries/regions.

Rationale: Directly comparative data on sepsis epidemiology and sepsis bundle implementation in countries of differing national wealth remain sparse. Objectives: To evaluate across countries/regions of differing income status in Asia 1) the prevalence, causes, and outcomes of sepsis as a reason for ICU admission and 2) sepsis bundle (antibiotic administration, blood culture, and lactate measurement) compliance and its association with hospital mortality. Methods: A prospective point prevalence study was conducted among 386 adult ICUs from 22 Asian countries/regions. Adult ICU participants admitted for sepsis on four separate days (representing the seasons of 2019) were recruited. Measurements and Main Results: The overall prevalence of sepsis in ICUs was 22.4% (20.9%, 24.5%, and 21.3% in low-income countries/regions [LICs]/lower middle-income countries/regions [LMICs], upper middle-income countries/regions, and high-income countries/regions [HICs], respectively; P < 0.001). Patients were younger and had lower severity of illness in LICs/LMICs. Hospital mortality was 32.6% and marginally significantly higher in LICs/LMICs than HICs on multivariable generalized mixed model analysis (adjusted odds ratio, 1.84; 95% confidence interval, 1.00-3.37; P = 0.049). Sepsis bundle compliance was 21.5% at 1 hour (26.0%, 22.1%, and 16.2% in LICs/LMICs, upper middle-income countries/regions, and HICs, respectively; P < 0.001) and 36.6% at 3 hours (39.3%, 32.8%, and 38.5%, respectively; P = 0.001). Delaying antibiotic administration beyond 3 hours was the only element independently associated with increased mortality (adjusted odds ratio, 2.53; 95% confidence interval, 2.07-3.08; P < 0.001). Conclusions: Sepsis is a common cause of admission to Asian ICUs. Mortality remains high and is higher in LICs/LMICs after controlling for confounders. Sepsis bundle compliance remains low. Delaying antibiotic administration beyond 3 hours from diagnosis is associated with increased mortality. Clinical trial registered with www.ctri.nic.in (CTRI/2019/01/016898).

Increased intra-abdominal pressure (IAP) is an important vital sign in critically ill patients and has a negative impact on morbidity and mortality. This study aimed to validate a novel non-invasive ultrasonographic approach to IAP measurement against the gold standard intra-bladder pressure (IBP) method. We conducted a prospective observational study in an adult medical ICU of a university hospital. IAP measurements using ultrasonography by two independent operators, with different experience levels (experienced, IAPUS1; inexperienced, IAPUS2), were compared with the gold standard IBP method performed by a third blinded operator. For the ultrasonographic method, decremental external pressure was applied on the anterior abdominal wall using a bottle filled with decreasing volumes of water. Ultrasonography looked at peritoneal rebound upon brisk withdrawal of the external pressure. The loss of peritoneal rebound was identified as the point where IAP was equal to or above the applied external pressure. Twenty-one patients underwent 74 IAP readings (range 2-15 mmHg). The number of readings per patient was 3.5 ± 2.5, and the abdominal wall thickness was 24.6 ± 13.1 mm. Bland and Altman's analysis showed a bias (0.39 and 0.61 mmHg) and precision (1.38 and 1.51 mmHg) for the comparison of IAPUS1 and IAPUS2 and vs. IBP, respectively with small limits of agreement that were in line with the research guidelines of the Abdominal Compartment Society (WSACS). Our novel ultrasound-based IAP method displayed good correlation and agreement between IAP and IBP at levels up to 15 mmHg and is an excellent solution for quick decision-making in critically ill patients.

Since the advent of critical care in the twentieth century, the core elements that are the foundation for critical care systems, namely to care for critically ill and injured patients and to save lives, have evolved enormously. The past half-century has seen dramatic advancements in diagnostic, organ support, and treatment modalities in critical care, with further improvements now needed to achieve personalized critical care of the highest quality. For critical care to be even higher quality in the future, advancements in the following areas are key: the physical ICU space; the people that care for critically ill patients; the equipment and technologies; the information systems and data; and the research systems that impact critically ill patients and families. With acutely and critically ill patients and their families as the absolute focal point, advancements across these areas will hopefully transform care and outcomes over the coming years.

BACKGROUND: Use of high-flow nasal cannula (HFNC) has become a regular intervention in the intensive care units especially in patients coming in with hypoxaemic respiratory failure. Clinical practices may differ from published literature. OBJECTIVES: The objective of this study was to determine the clinical practices of physicians and respiratory therapists (RTs) on the use of HFNC. METHODS: A retrospective observational study looking at medical records on HFNC usage from January 2015 to September 2017 was performed and was followed by a series of questions related to HFNC practices. The survey involved physicians and RTs in intensive care units from multiple centres in Singapore from January to April 2018. Indications and thresholds for HFNC usage with titration and weaning practices were compared with the retrospective observational study data. RESULTS: One hundred twenty-three recipients (69.9%) responded to the survey and reported postextubation (87.8%), pneumonia in nonimmunocompromised (65.9%), and pneumonia in immunocompromised (61.8%) patients as the top three indications for HFNC. Of all, 39.8% of respondents wanted to use HFNC for palliative intent. Similar practices were observed in the retrospective study with the large cohort of 63% patients (483 of the total 768 patients) where HFNC was used for acute hypoxaemic respiratory failure and 274 (35.7%) patients to facilitate extubation. The survey suggested that respondents would initiate HFNC at a lower fraction of inspired oxygen (FiO2), higher partial pressure of oxygen to FiO2 ratio, and higher oxygen saturation to FiO2 ratio for nonpneumonia patients than patients with pneumonia. RTs were less likely to start HFNC for patients suffering from pneumonia and interstitial lung disease than physicians. RTs also preferred adjustment of FiO2 to improve oxygen saturations and noninvasive ventilation for rescue. CONCLUSIONS: Among the different intensive care units surveyed, the indications and thresholds for the initiation of HFNC differed in the clinical practices of physicians and RTs.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented pressure on healthcare system globally. Lack of high-quality evidence on the respiratory management of COVID-19-related acute respiratory failure (C-ARF) has resulted in wide variation in clinical practice. METHODS: Using a Delphi process, an international panel of 39 experts developed clinical practice statements on the respiratory management of C-ARF in areas where evidence is absent or limited. Agreement was defined as achieved when > 70% experts voted for a given option on the Likert scale statement or > 80% voted for a particular option in multiple-choice questions. Stability was assessed between the two concluding rounds for each statement, using the non-parametric Chi-square (χ2) test (p < 0·05 was considered as unstable). RESULTS: Agreement was achieved for 27 (73%) management strategies which were then used to develop expert clinical practice statements. Experts agreed that COVID-19-related acute respiratory distress syndrome (ARDS) is clinically similar to other forms of ARDS. The Delphi process yielded strong suggestions for use of systemic corticosteroids for critical COVID-19; awake self-proning to improve oxygenation and high flow nasal oxygen to potentially reduce tracheal intubation; non-invasive ventilation for patients with mixed hypoxemic-hypercapnic respiratory failure; tracheal intubation for poor mentation, hemodynamic instability or severe hypoxemia; closed suction systems; lung protective ventilation; prone ventilation (for 16-24 h per day) to improve oxygenation; neuromuscular blocking agents for patient-ventilator dyssynchrony; avoiding delay in extubation for the risk of reintubation; and similar timing of tracheostomy as in non-COVID-19 patients. There was no agreement on positive end expiratory pressure titration or the choice of personal protective equipment. CONCLUSION: Using a Delphi method, an agreement among experts was reached for 27 statements from which 20 expert clinical practice statements were derived on the respiratory management of C-ARF, addressing important decisions for patient management in areas where evidence is either absent or limited. TRIAL REGISTRATION: The study was registered with Clinical trials.gov Identifier: NCT04534569.

OBJECTIVE: To assess the number of adult critical care beds in Asian countries and regions in relation to population size. DESIGN: Cross-sectional observational study. SETTING: Twenty-three Asian countries and regions, covering 92.1% of the continent's population. PARTICIPANTS: Ten low-income and lower-middle-income economies, five upper-middle-income economies, and eight high-income economies according to the World Bank classification. INTERVENTIONS: Data closest to 2017 on critical care beds, including ICU and intermediate care unit beds, were obtained through multiple means, including government sources, national critical care societies, colleges, or registries, personal contacts, and extrapolation of data. MEASUREMENTS AND MAIN RESULTS: Cumulatively, there were 3.6 critical care beds per 100,000 population. The median number of critical care beds per 100,000 population per country and region was significantly lower in low- and lower-middle-income economies (2.3; interquartile range, 1.4-2.7) than in upper-middle-income economies (4.6; interquartile range, 3.5-15.9) and high-income economies (12.3; interquartile range, 8.1-20.8) (p = 0.001), with a large variation even across countries and regions of the same World Bank income classification. This number was independently predicted by the World Bank income classification on multivariable analysis, and significantly correlated with the number of acute hospital beds per 100,000 population (r = 0.19; p = 0.047), the universal health coverage service coverage index (r = 0.35; p = 0.003), and the Human Development Index (r = 0.40; p = 0.001) on univariable analysis. CONCLUSIONS: Critical care bed capacity varies widely across Asia and is significantly lower in low- and lower-middle-income than in upper-middle-income and high-income countries and regions.

BACKGROUND: Pulmonary embolism (PE) care has traditionally been fragmented. The newly introduced Pulmonary Embolism Response Team (PERT) model provides streamlined care based on expedient, multi-disciplinary decision-making. This study aimed to quantify the impact of PERT, as part of a hospital-wide PE treatment protocol, on clinical outcomes. METHODS: Consecutive adult patients with acute PE diagnosed via computed tomography pulmonary angiogram (CTPA) were included. The PERT and treatment protocol were introduced in January 2015. Patient characteristics, therapies, quality measures of CTPA reporting, and clinical outcomes of PE patients treated for 2 years before and after implementation of these changes were evaluated. Primary endpoints were median length of stay in intensive care (ICU) and survival to discharge. RESULTS: A total of 321 consecutive PE patients were enrolled, of which 154 (treated in 2013-2014) and 167 (2015-2016) patients formed the historical control and study groups, respectively. Implementation of the algorithm was associated with less variance in anticoagulation and improved reporting of right heart strain parameters on CTPA. The ICU stay was reduced from a median of 5 to 2 days (p < 0.01). Eligible massive PE patients receiving reperfusion increased from 30% to 92% (p = 0.01), with mean delay from diagnosis to reperfusion decreasing from 763 to 181 minutes (p < 0.01). Bleeding complications were not increased, but overall survival to discharge remained unchanged. CONCLUSIONS: Introducing a PERT and treatment protocol reduced ICU stay, enhanced quality measures, and improved access of massive PE patients to reperfusion therapies, without increasing bleeding complications or health care costs.

PURPOSE:: We aim to determine whether hyperlactatemia, which suggests multi-organ dysfunction and impaired organic substrate metabolism, may predict intolerance to regional citrate anticoagulation (RCA) during continuous venovenous hemofiltration (CVVH). METHODS:: We performed a single-center, retrospective observational study in critically ill patients with acute kidney injury or end-stage renal disease and evaluated the association of peak serum lactate levels with citrate intolerance (CI) during the initial 72 hours of RCA-CVVH, defined by serum total-to-ionized calcium >2.5 plus systemic hypocalcemia. RESULTS:: Eighty-eight patients were studied (aged 59 ± 14 years, 66% males, Acute Physiology and Chronic Health Evaluation II: 31 ± 8). Citrate was dosed at median 2.1 mmol/L of blood flow, with citrate load of 30 mmol/h, and CVVH effluent of 43 mL/kg/h. Twenty patients developed CI. Comparing patients with CI versus none, peak lactate levels were 8 (5-11) versus 3 (2-6) mmol/L, calcium replacement was 13 (10-17) versus 11 (8-12) mmol/h, and standard base excess was -4 (-12 to 1) versus 2(-4 to 7) mmol/L, respectively ( P < .05). Citrate intolerance developed in 38%, 44%, and 55%, in patients with peak lactate >4, >6, >7 mmol/L, respectively, versus 7% in those with peak lactate ≤4 mmol/L ( P ≤ .001), despite comparable citrate load and effluent rates across all categories. On multivariate analysis, hyperlactatemia and hyperbilirubinemia predicted CI ( P ≤ .01), which was associated with increasing calcium infusion requirement. Higher peak lactate from >4 to >7 mmol/L predicted CI with graded increase in odds ratio and specificity from 59% to 87%, but the corresponding negative predictive value from 93% to 87%. Area under nonparametric receiver operating characteristic curve for peak lactate and CI was 0.78. CONCLUSION:: Hyperlactatemia predicts CI during RCA-CVVH with reasonable discriminatory performance in critically ill patients. Serum lactate surveillance may help preempt issues with citrate toxicity.

OBJECTIVES: To compare physicians' perceptions and practice of end-of-life care in the ICU in three East Asian countries cultures similarly rooted in Confucianism. DESIGN: A structured and scenario-based survey of physicians who managed ICU patients from May 2012 to December 2012. SETTING: ICUs in China, Korea, and Japan. SUBJECTS: Specialists who are either intensivists or nonintensivist primary attending physicians in charge of patients (195 in China, 186 in Korea, 224 in Japan). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Country was independently associated with differences in the practice of limiting multiple forms of life-sustaining treatments on multivariable generalized linear model analysis. Chinese respondents were least likely to apply do-not-resuscitate orders, even if they existed (p < 0.001). Japanese respondents were most likely to practice do not resuscitate for terminally ill patients during cardiac arrest, even when no such prior order existed (p < 0.001). Korean respondents' attitudes were in between those of Chinese and Japanese respondents as far as withdrawing total parenteral nutrition, antibiotics, dialysis, and suctioning was concerned. Chinese respondents were most uncomfortable discussing end-of-life care issues with patients, while Japanese respondents were least uncomfortable (p < 0.001). Chinese respondents were more likely to consider financial burden when deciding on limiting life-sustaining treatment (p < 0.001). Japanese respondents felt least exposed to personal legal risks when limiting life-sustaining treatment (p < 0.001), and the Korean respondents most wanted legislation to guide this issue (p < 0.001). The respondents' gender, religion, clinical experience, and primary specialty were also independently associated with the different perceptions of end-of-life care. CONCLUSIONS: Despite similarities in cultures and a common emphasis on the role of family, differences exist in physician perceptions and practices of end-of-life ICU care in China, Korea, and Japan. These findings may be due to differences in the degree of Westernization, national healthcare systems, economic status, and legal climate.

PURPOSE OF REVIEW: Published data and practice recommendations on end-of-life (EOL) generally reflect Western practice frameworks. Understanding worldwide practices is important because improving economic conditions are promoting rapid expansion of intensive care services in many previously disadvantaged regions, and increasing migration has promoted a new cultural diversity previously predominantly unicultural societies. This review explores current knowledge of similarities and differences in EOL practice between regions and possible causes and implications of these differences. RECENT FINDINGS: Recent observational and survey data shows a marked variability in the practice of withholding and withdrawing life sustaining therapy worldwide. Some evidence supports the view that culture, religion, and socioeconomic factors influence EOL practice, and individually or together account for differences observed. There are also likely to be commonly desired values and expectations for EOL practice, and recent attempts at establishing where worldwide consensus may lie have improved our understanding of shared values and practices. SUMMARY: Awareness of differences, understanding their likely complex causes, and using this knowledge to inform individualized care at EOL is likely to improve the quality of care for patients. Further research should clarify the causes of EOL practice variability, monitor trends, and objectively evaluate the quality of EOL practice worldwide.

BACKGROUND AND OBJECTIVE: COPD is a complex condition with a heavy burden of disease. Many multidimensional tools have been studied for their prognostic utility but none has been universally adopted as each has its own limitations. We hypothesize that a multidimensional tool examining four domains, health-related quality of life, disease severity, systemic effects of disease and patient factors, would better categorize and prognosticate these patients. METHODS: We first evaluated 300 patients and found four factors that predicted mortality: BMI, airflow obstruction, St George's Respiratory Questionnaire and age (BOSA). A 10-point index (BOSA index) was constructed and prospectively validated in a cohort of 772 patients with all-cause mortality as the primary outcome. Patients were categorized into their respective BOSA quartile group based on their BOSA score. Multivariate survival analyses and receiver operator characteristic (ROC) curves were used to assess the BOSA index. RESULTS: Patients in BOSA Group 4 were at higher risk of death compared with their counterparts in Group 1 (hazard ratio (HR): 0.29, 95% CI: 0.16-0.51, P < 0.001) and Group 2 (HR: 0.53, 95% CI: 0.34-0.82, P = 0.005). Race and gender did not affect mortality. The area under the ROC curve for BOSA index was 0.690 ± 0.025 while that for Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2011 was 0.641 ± 0.025 (P = 0.17). CONCLUSION: The BOSA index predicts mortality well and it has at least similar prognostic utility as GOLD 2011 in Asian patients. The BOSA index is a simple tool that does not require complex equipment or testing. It has the potential to be used widely.

OBJECTIVES: Despite being the epicenter of recent pandemics, little is known about critical care in Asia. Our objective was to describe the structure, organization, and delivery in Asian ICUs. DESIGN: A web-based survey with the following domains: hospital organizational characteristics, ICU organizational characteristics, staffing, procedures and therapies available in the ICU and written protocols and policies. SETTING: ICUs from 20 Asian countries from April 2013 to January 2014. Countries were divided into low-, middle-, and high-income based on the 2011 World Bank Classification. SUBJECTS: ICU directors or representatives. MEASUREMENTS AND MAIN RESULTS: Of 672 representatives, 335 (50%) responded. The average number of hospital beds was 973 (SE of the mean [SEM], 271) with 9% (SEM, 3%) being ICU beds. In the index ICUs, the average number of beds was 21 (SEM, 3), of single rooms 8 (SEM, 2), of negative-pressure rooms 3 (SEM, 1), and of board-certified intensivists 7 (SEM, 3). Most ICUs (65%) functioned as closed units. The nurse-to-patient ratio was 1:1 or 1:2 in most ICUs (84%). On multivariable analysis, single rooms were less likely in low-income countries (p = 0.01) and nonreferral hospitals (p = 0.01); negative-pressure rooms were less likely in private hospitals (p = 0.03) and low-income countries (p = 0.005); 1:1 nurse-to-patient ratio was lower in private hospitals (p = 0.005); board-certified intensivists were less common in low-income countries (p < 0.0001) and closed ICUs were less likely in private (p = 0.02) and smaller hospitals (p < 0.001). CONCLUSIONS: This survey highlights considerable variation in critical care structure, organization, and delivery in Asia, which was related to hospital funding source and size, and country income. The lack of single and negative-pressure rooms in many Asian ICUs should be addressed before any future pandemic of severe respiratory illness.

BACKGROUND: Swallowing difficulties are common, and dysphagia occurs frequently in intensive care unit (ICU) patients after extubation. Yet, no guidelines on postextubation swallowing assessment exist. We aimed to investigate the safety and effectiveness of nurse-performed screening (NPS) for postextubation dysphagia in the medical ICU. METHODS: We conducted a retrospective cohort study of mechanically ventilated patients who were extubated in a 20-bed medical ICU. Phase I (no NPS, October 2012 to January 2014) and phase II (NPS, February 2014 to July 2015) were compared. In phase II, extubated patients received NPS up to three times on consecutive days; patients who failed were referred to speech-language pathologists. Outcomes analyzed included oral feeding at ICU discharge, reintubation, ICU readmission, postextubation pneumonia, ICU and/or hospital mortality, and ICU and/or hospital length of stay (LOS). Subgroup analysis was done for patients extubated after >72 h of mechanical ventilation, as the latter may predispose patients to postextubation dysphagia. Multivariable adjustments for Acute Physiology and Chronic Health Evaluation (APACHE) II score and comorbidities were done because of baseline differences between the phases. RESULTS: A total of 468 patients were studied (281 in phase I, 187 in phase II). Patients in phase II had higher APACHE II scores than those in phase I (27.2 ± 8.2 vs. 25.4 ± 8.2; P = 0.018). Despite this, patients in phase II showed a 111 % increase in (the odds of) oral feeding at ICU discharge and a 59 % decrease in postextubation pneumonia (multivariate P values 0.001 and 0.006, respectively). In the subgroup analysis, NPS was associated with a 127 % increase in oral feeding at ICU discharge, an 80 % decrease in postextubation pneumonia, and a 25 % decrease in hospital LOS (multivariate P values 0.021, 0.004, and 0.009, respectively). No other outcome differences were found. CONCLUSIONS: NPS for dysphagia is safe and may be superior to no screening with respect to several patient-centered outcomes.

Mortality rates for severe community-acquired pneumonia (CAP) range from 17 to 48 % in published studies.In this review, we searched PubMed for relevant papers published between 1981 and June 2016 and relevant files. We explored how early and aggressive management measures, implemented within 24 hours of recognition of severe CAP and carried out both in the emergency department and in the ICU, decrease mortality in severe CAP.These measures begin with the use of severity assessment tools and the application of care bundles via clinical decision support tools. The bundles include early guideline-concordant antibiotics including macrolides, early haemodynamic support (lactate measurement, intravenous fluids, and vasopressors), and early respiratory support (high-flow nasal cannulae, lung-protective ventilation, prone positioning, and neuromuscular blockade for acute respiratory distress syndrome).While the proposed interventions appear straightforward, multiple barriers to their implementation exist. To successfully decrease mortality for severe CAP, early and close collaboration between emergency medicine and respiratory and critical care medicine teams is required. We propose a workflow incorporating these interventions.

BACKGROUND: Pathogens are often not identified in severe community-acquired pneumonia (CAP), and the few studies using polymerase chain reaction (PCR) techniques for virus detection are from temperate countries. OBJECTIVE: This study assesses if PCR amplification improves virus and bacteria detection, and if viral infection contributes to mortality in severe CAP in a tropical setting, where respiratory pathogens have less well-defined seasonality. METHODS: In this cohort study of patients with severe CAP in an intensive care unit, endotracheal aspirates for intubated patients and nasopharyngeal swabs for non-intubated patients were sent for PCR amplification for respiratory viruses. Blood, endotracheal aspirates for intubated patients, and sputum for non-intubated patients were analysed using a multiplex PCR system for bacteria. RESULTS: Out of 100 patients, using predominantly cultures, bacteria were identified in 42 patients; PCR amplification increased this number to 55 patients. PCR amplification identified viruses in 32 patients. In total, only bacteria, only viruses, and both bacteria and viruses were found in 37, 14, and 18 patients, respectively. The commonest viruses were influenza A H1N1/2009 and rhinovirus; the commonest bacterium was Streptococcus pneumoniae. Hospital mortality rates for patients with no pathogens, bacterial infection, viral infection, and bacterial-viral co-infection were 16.1, 24.3, 0, and 5.6%, respectively (p = 0.10). On multivariable analysis, virus detection was associated with lower mortality (adjusted odds ratio 0.12, 95% confidence interval 0.2-0.99; p = 0.049). CONCLUSIONS: Viruses and bacteria were detected in 7 of 10 patients with severe CAP with the aid of PCR amplification. Viral infection appears to be independently associated with lower mortality.
