MedicalResearch.com Interview with: François Lamontagne MD MSc (pharmacology) MSc (CEB) Professor of Medicine at the Université de Sherbrooke Endowed research chair on patient-centred research Dr. Neill Adhikari MDCM, M.Sc. Sunnybrook Research Institute and University of Toronto Toronto, Canada MedicalResearch.com:  What is the background for this study?  Response: The use of intravenous vitamin C for sepsis has been a hot topic for a few years. It was biologically plausible that vitamin C could reduce organ injury and death by scavenging reactive oxygen species and modulating the immune response to sepsis. It also seemed like an intervention that would be reasonably easy to administer globally should it prove beneficial. On the other hand, no intervention is benign and every aspect of health care should be rigorously studied. Regarding vitamin C, there were strongly held opinions in both camps and this motivated us to design and conduct the LOVIT trial.

MedicalResearch.com Interview with: Hirotaka Kato, PhD Graduate School of Health Management Keio University  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Physicians are increasingly engaging in clinical practice on a part-time basis, but little is known about the quality of care provided by these physicians. In this analysis of nationally representative data of the elderly patients admitted to hospitals, we found that patients treated by hospitalists who worked more clinical days per year had significantly lower 30-day mortality compared with patients treated by hospitalists working fewer clinical days, even after accounting for the differences in severity of illness.

Response: Prone positioning has been shown to improve oxygenation and reduce mortality in intubated patients with acute respiratory distress syndrome (ARDS), as placing patients on their stomachs can help open alveoli and reduce ventilation to perfusion mismatch. At early pandemic, clinicians tried prone positioning for non-intubated patients with COVID-19 and found improvement in oxygenation. However, the evidence for patient outcomes such as intubation or mortality is still lacking. Thus we organized this international, multicenter, randomized controlled meta-trial, with 41 hospitals in 6 countries participated.

Lazar MD Jeffrey H Jennings, MD Pulmonary and Critical Care specialists Henry Ford Hospital Detroit Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Persons of color who are infected with COVID-19 have a higher incidence of hospitalization and death when compared to white patients.  However, it was previously unknown if there was a difference in outcomes based upon race in patients who are sick enough to be treated in an intensive care unit (ICU). Our study found that race made no difference in ICU outcomes. MedicalResearch.com: What should readers take away from your report? Response: Lack of racial differences in survival and other meaningful outcomes in the intensive care unit may be related to the highly protocolized nature of care and experience of the critical care team.

Response: Patient surveys have shown that most people prefer to die at home at the end-of-life. However, during the initial wave of the COVID-19 pandemic, anecdotal evidence from our colleagues and findings from a prior study published in the Journal of the American Geriatrics Society suggested that majority of COVID-19 decedents died in a medical facility. However, less is known about care intensity at the end-of-life according to place of death among patients who died of COVID-19. Therefore, we characterized end-of-life care by place of death among COVID-19 decedents at Mass General Brigham (MGB), the largest health system in Massachusetts.

Response: We have known for some time that COVID19 is characterized by hypercoagulability or excess blood clotting.  In fact, the incidence of blood clots in the lungs (pulmonary emboli) is as high 20% and is two to three times more common in COVID19 than in severe influenza.  Further, autopsies of patients who died from COVID19 have shown that endothelial cells (cells that line the blood vessels) are damaged and that "micro clots" form in multiple organs.  Together, these findings strongly suggest that excess blood clotting and endothelial cell dysfunction are defining features of severe COVID19. For several months, my colleagues and I have been interested in whether aspirin might improve outcomes in patients with severe COVID19.  In prior observational research studies, aspirin was found to be protective in patients with severe lung injury.  The general idea is that aspirin reduces platelet aggregates in the lung and this improves outcome.  Unfortunately, in a prior randomized controlled study (LIPS-A) aspirin was not shown to reduce the incidence of acute respiratory distress syndrome.  Nevertheless, COVID19 has unique features that make aspirin more likely to be effective.  Mainly COVID19 is associated with hypercoagulability to a greater degree than in other viral illnesses.

Response: With the resurgence of COVID-19 and the likely seasonal resurgences, we were interested in whether those in low-income areas would be able to get access to the hospital care they might need. So we examined the distribution of ICU beds across the country and also looked at differences in the availability of ICU beds by household income in the community.

Response: There are millions of hospitalizations every year in the United States (US) that include a stay in an intensive care unit (ICU). Such ICU stays put strain on health system resources, may be unwanted by patients, and are costly to society. As the population of the US gets older and more medically complex, some have argued that we need more ICU beds and a larger ICU workforce to keep pace. We hypothesized that some proportion of these ICU admissions could be prevented with early and appropriate outpatient care. Such a strategy would alleviate some of the strains and costs associated with ICU stays. If an appreciable proportion of ICU stays were preventable in this way, it would strengthen support for an alternative population-health based framework instead of further investments in the ICU delivery infrastructure.

MedicalResearch.com Interview with: MedicalResearch.com Interview with: Regis Goulart Rosa, MD, PhD Responsabilidade Social - PROADI Hospital Moinhos de Vento MedicalResearch.com: What is the background for this study? Response: The debate about visiting policies in adult ICUs is of broad and current interest in critical care, with strong advocacy in favour of flexible family visitation models in order to promote patient- and family-centred care. However, the proportion of adult ICUs with unrestricted visiting hours is very low. Data from the literature show that 80% of hospitals in the United Kingdom and USA adopt restrictive ICU visiting policies. Among ICUs with restrictive visiting hours, published studies show that the daily visiting time ranges from a median of 1 hour in Italy to a mean of 4.7 hours in France. In agreement with this scenario, most adult ICUs in Brazil follow a restrictive visitation model, in which family members are allowed to visit the critically ill patient from 30 minutes to 1 hour, once or twice a day. These restrictive visitation models have been justified by the theoretical risks associated with unrestricted visiting hours, mainly infectious complications, disorganization of care, and burnout. Controversially, these risks have not been consistently confirmed by the scarce literature on the subject, and flexible ICU visiting hours have been proposed as a means to prevent delirium among patients and improve family satisfaction. MedicalResearch.com: What are the main findings? Response: Disappointingly, studies evaluating the effectiveness and safety of flexible ICU visiting hours are scarce. To date, no large randomized trials have assessed the impact of a flexible visiting model on patients, family members, and ICU staff, and this evidence gap may constitute a barrier to the understanding of the best way to implement and improve ICU visiting policies. In the present pragmatic cluster-randomized crossover trial (The ICU Visits Study), we engaged 1,685 patients, 1,295 family members, and 826 ICU professionals from 36 adult ICUs in Brazil to compare a flexible visitation model (12 hours/day plus family education) vs. the standard restricted visitation model (median 90 minutes per day). We found that the flexible visitation did not significantly reduce the incidence of delirium among patients, but was associated with fewer symptoms of anxiety and depression and higher satisfaction with care among family members in comparison to the usual restricted visitation. Also, the flexible visitation did not increase the incidence of ICU-acquired infections and ICU staff burnout, which are major concerns when adopting this intervention. MedicalResearch.com: What should readers take away from your report? Response: Considering the evidence suggesting that most adult ICUs restrict the presence of family members, our results provide useful and relevant information that may influence the debate about current ICU visitation policies around the world. First, a flexible visitation policy that permits flexible family visitation in ICU (up to 12 hour per day) is feasible, given the high adherence of participant ICUs to implementation in The ICU Visits Study. Second, the flexible family supported by family education is safe regarding the occurrence of infections, disorganization of care or staff burnout. Third, family members - a commonly missing piece of the critical care puzzle - seem to benefit from the flexible visitation model through higher satisfaction with care and less symptoms of anxiety and depression. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: Future research might focus on the following topics: 1) methods of implementation of flexible visiting models in ICUs; 2) Family support interventions in the context of flexible ICU visiting hours (e.g.: psychological and social support, support for shared decision making, peer support, and comfort); and 3) How flexible ICU visiting hours affects patient, family member and staff outcome at long-term. Disclosures: The ICU Visits study was funded by the Brazilian Ministry of Health through the Brazilian Unified Health System Institutional Development Program (PROADI-SUS).

What are the main findings? Response: Unconsciousness is common and predicting recovery is challenging – often inaccurate. Many patients do not show movements on commands and typically this is interpreted as unconsciousness. Some of these patients may be able to have brain response to these commands raising the possibility of some preservation of consciousness. This has previously been shown months or years after the injury mostly using MRI. We were able to detect this activation at the bedside in the ICU shortly after brain injury. For this we applied machine learning to the EEG to distinguish the brain’s responses to commands. Patients that showed this activation were more likely to follow commands prior to discharge and had better outcomes one year later.

What are the main findings? Response: Our study emphasizes the importance of team work and real-time communication in a quality-improvement project within the neonatal intensive care unit (NICU) setting. Through bedside huddles, weekly reviews of apparent cause analysis reports reducing the frequency of X-rays and the creation of an Airway Safety Protection Team, we were able to focus not only on  reducing unintended extubations, but also on the quality-improvement project’s effect on our staff. Adhering to simple quality principles enabled us to ensure that all members of our staff were heard and had a positive effect on the progress of our project. This allowed us to implement and sustain a series of simple changes that standardized steps associated with securing and maintaining an endotracheal tube (ET). Unintended extubations are the fourth-most common adverse event in the nation’s NICUs. Continual monitoring via this quality-improvement project allowed us to intervene when our rates increased and further pushed our unintended extubation rate downward.

What are the main findings? Response: Against the backdrop of rising health care costs, and the increasing share of those costs that consumers bear, studies show people are interested in finding health care cost information and engaging with their providers on issues of cost. We were interested in learning to what extent, if any, discussion or consideration of cost would be documented in electronic health records. Using machine learning techniques to extract data from unstructured notes, we examined 46,146 narrative clinical notes from ICU admissions. We found that approximately 4% of admissions had at least one note with financially relevant content. That financial content included documentation of cost as a barrier to adhering to treatment prior to admission, and as a consideration in treatment and discharge planning.

Response: Delirium is a serious problem in Intensive Care Units around the world. Approximately 80% of mechanically ventilated patients develop delirium, acute confusion, while in the ICU. Once thought to be a benign side effect of the ICU environment, research now shows that delirium is linked to a myriad of negative outcomes for patients which include longer ICU and Hospital stays, prolonged time on the ventilator, increased cost, long-term cognitive impairment and even mortality. For a half a century clinicians have been using haloperidol, an typical antipsychotic, to treat delirium in the ICU. However, there has never been evidence to support the use of haloperidol or its pharmacologic cousins, the atypical antipsychotics, to treat delirium. These drugs have serious side effects that include heart arrhythmias, muscle spasms, restlessness and are associated with increased mortality when given for prolonged periods in the outpatient settings leading to a black box warning for their use in this setting. The MIND-USA study was a double blind placebo controlled trial which evaluated the efficacy and safety of antipsychotics (i.e., haloperidol and ziprasidone) in the treatment delirium in adult ICU patients.

Response: 50-60 million people each year suffer a traumatic brain injury (TBI) . When the injury is severe only one half are able to live independently afterwards. Cooling the brain (hypothermia) is often used in intensive care units for decades to  decrease inflammation and brain swelling and hopefully to improve outcomes, but clinical staff have had uncertainty whether benefits outweigh complications. We conducted the largest randomised trial of hypothermia in TBI, in 500 patients, in 6 countries, called POLAR. We started cooling by ambulance staff, to give hypothermia the best chance to benefit patients. We continued for 3-7 days in hospital ind ICU. We measured functional outcomes at 6 months.

Wesley Ely is a Professor of medicine at Vanderbilt University School of Medicine with subspecialty training in Pulmonary and Critical Care Medicine.  MedicalResearch.com: What is the background for this study? Response: Critically ill patients are not benefitting from antipsychotic medications that have been used to treat delirium in intensive care units (ICUs) for more than four decades, according to a study released today in the New England Journal of Medicine. Each year, more than 7 million hospitalized patients in the United States experience delirium, making them disoriented, withdrawn, drowsy or difficult to wake. The large, multi-site MIND USA (Modifying the INcidence of Delirium) study sought to answer whether typical and atypical antipsychotics — haloperidol or ziprasidone —affected delirium, survival, length of stay or safety. Researchers screened nearly 21,000 patients at 16 U.S. medical centers. Of the 1,183 patients on mechanical ventilation or in shock, 566 became delirious and were randomized into groups receiving either intravenous haloperidol, ziprasidone or placebo (saline).

MedicalResearch.com Interview with: MedicalResearch.com Interview with: Gili Regev-Yochay, MD, Lead author Director of the Infection Prevention & Control Unit Sheba Medical Center Tel HaShomer, Israel.  MedicalResearch.com: What is the background for this study? Response: CPE (Carbapenemase producing Enterobacteriaceae) is endemic in Israel. In our ICU we had a prolonged CPE outbreak with one particular bacteria, which is not that common (OXA-48 producing-Serratia marcescens).  Enhancing our regular control measures (hand hygiene, increased cleaning etc..) did not contain the outbreak. MedicalResearch.com: What are the main findings?  Response: The outbreak source were the sink-traps in nearly all the patient rooms, which were contaminated with this same bacteria. Once we understood that this was the source we took two measures: 1) Sink decontamination efforts, including intensive chlorine washes of the drainage and water system, replacement of all sink-traps, acetic acid treatment and more, all these efforts were only partially and only temporarily successful. So that even today, after a year of such efforts and a period in which we didn't have any patients with this infection, the drainage system is still contaminated with these bugs and they grow in the sink-traps and can be found in the sink outlets. 2) The second measure we took was an educational intervention, where we engaged the ICU team through workshops to the issue of the contaminated sinks and together enforced strict "sink-use guidelines" (sinks are to be used ONLY for hand washing, prohibiting placement of any materials near the sinks, etc.). Using these two measure the outbreak was fully contained. To date, nearly 1.5 years since the last outbreak case, we did not have any further infections in our ICU patients with this bug. MedicalResearch.com: What should readers take away from your report? Response: Sink-traps and drainage systems can be a major source of CPE transmission. While traditionally CPE outbreaks were attributed to patient-to patient transmission, the environment and particularly water and drainage system appears to play a major role. MedicalResearch.com: What recommendations do you have for future research as a result of this work?  Response: There is urgent need to find a technological solution for drainage system contaminations. While some have suggested to get rid of sinks in ICU this is probably not realistic in the era of emerging Clostridium infections (where washing hands, and not only alcohol rubs are needed).  Citation: Gili Regev-Yochay, Gill Smollan, Ilana Tal, Nani Pinas Zade, Yael Haviv, Valery Nudelman, Ohad Gal-Mor, Hanaa Jaber, Eyal Zimlichman, Nati Keller, Galia Rahav. Sink traps as the source of transmission of OXA-48–producing Serratia marcescens in an intensive care unit. Infection Control & Hospital Epidemiology, 2018; 1 DOI: 1017/ice.2018.235 [wysija_form id="3"] [last-modified]     The information on MedicalResearch.com is provided for educational purposes only, and is in no way intended to diagnose, cure, or treat any medical or other condition.

MedicalResearch.com Interview with: “cycling” by Urs Steiner is licensed under CC BY 2.0Guillaume Fossat, Physiotherapist and Thierry Boulain, M.D. Médecine Intensive Réanimation Centre Hospitalier Régional Orléans, France MedicalResearch.com: What is the background for this study? Response: Critically ill patients may suffer terrific muscle wasting during their intensive care unit stay. In most patients, particularly those with sepsis or other high inflammatory states, this is due to proteolytic pathways runaway that may persist as long as the cause of inflammation has not been eliminated. What is more, forced rest, as the one imposed to severely ill patients who need sedation to tolerate artificial respiratory support also induces muscle deconditioning and mass loss. In short, the more you are severely and acutely ill, the more you breakdown your muscle proteins and use the catabolic byproducts to fuel the rest of your organism. As a result of this sort of autophagy, intensive care unit survivors may have lost tens of muscle mass kilograms at discharge, to the point that they have lost all or parts of their functional autonomy. The personal and social burden is considerable as muscle weakness may persist several years after hospital discharge. In the 2000’s, physiotherapy and early rehabilitation during intensive care have emerged as a way to counteract the autophagic muscle wasting and help patients to speed up their return to functional autonomy. Therefore, a standardized early rehabilitation that consists in early muscle exercises, systematic lowering or interruption of sedative drugs dosages to allow prompt patient’s awaking, early transfer to chair and early first walk try, has become the standard of care. However, to what extent, when and how muscles should be exercised during the intensive care unit stay in order to optimize the positive effects of rehabilitation remains a nearly blank clinical research area. In-bed leg cycling and electrical muscle stimulation, each for their part, have shown encouraging results. In our study, we sought to know if the very early combination of both could improve global muscle strength in survivors at intensive care unit discharge.

White, M.D., M.A.S. Director of the Clinical Research Investigation and Systems Modeling of Acute Illness (CRISMA) Center’s Program on Ethics and Decision Making in  Department of Critical Care Medicine University of Pittsburgh  MedicalResearch.com: What is the background for this study?  Response: We set out to test the effectiveness of PARTNER (PAiring Re-engineered ICU Teams with Nurse-driven Emotional Support and Relationship-building). PARTNER is delivered by the interprofessional team in the ICU, consisting of nurses, physicians, spiritual care providers, social workers and others who play a part in patient care. The program is overseen by nurse-leaders in each ICU who receive 12 hours of advanced communication skills training to support families. The nurses meet with the families daily and arrange interdisciplinary clinician-family meetings within 48 hours of a patient coming to the ICU. A quality improvement specialist helps to incorporate the family support intervention into the clinicians’ workflow. PARTNER was rolled out at five UPMC ICUs with different patient populations and staffing. It was implemented in a staggered fashion so that every participating ICU would eventually get PARTNER. Before receiving PARTNER, the ICUs continued their usual methods of supporting families of hospitalized patients. None of the ICUs had a set approach to family communication or required family meetings at regular intervals before receiving PARTNER. A total of 1,420 adult patients were enrolled in the trial, and 1,106 of these patients’ family members agreed to be a part of the study and its six-month follow-up surveys. The patients were very sick, with about 60 percent dying within six months of hospitalization and less than 1 percent living independently at home at that point.

What are the main findings?  Response: Most previous studies of opioid use in health care have focused on the outpatient setting. But opioids are often introduced during hospitalization. That’s something clinicians can control, so we looked at inpatient prescription of these drugs to identify targets that may reduce opioid use once patients are out of the hospital. We analyzed the medical records of 357,413 non-obstetrical adults hospitalized between 2010 and 2014 at 12 University of Pittsburgh Medical Center (UPMC) hospitals in southwestern Pennsylvania. The region is one of the areas of the country where opioid addiction is a major public health problem. We focused on the 192,240 patients who had not received an opioid in the year prior to their hospitalization – otherwise known as “opioid naïve” patients. Nearly half (48 percent) of these patients received an opioid while hospitalized.  After discharge, those patients receiving hospital opioids were more than twice as likely to report outpatient opioid use within 90-days (8.4 percent vs. 4.1 percent). Patients who receive an opioid for most of their hospital stay and patients who are still taking an opioid within 12 hours of being discharged from the hospital appear more likely to fill a prescription for opioids within 90 days of leaving the hospital.

Response: High-risk patients, such as the critically ill, with suspected bacterial infections require prompt treatment with appropriate empiric therapy to improve survival. Given the high prevalence of multidrug-resistant (MDR) Pseudomonas aeruginosa in the ICU setting, new safe and broadly effective treatment options are needed for critically ill patients requiring antipseudomonal agents. Ceftolozane/tazobactam (C/T) is an antipseudomonal cephalosporin/beta-lactamase inhibitor combination with broad in vitro activity against Gram-negative pathogens, including MDR P. aeruginosa and many extended-spectrum beta-lactamase (ESBL) producers. It is FDA approved for complicated intra-abdominal and urinary tract infections in adults at 1.5g (1g/0.5g) q8h. C/T is currently being studied at 3g (2g/1g) q8h, for the treatment of ventilated nosocomial pneumonia, in the ASPECT-NP Phase 3 trial. This Phase 1 pharmacokinetic (PK) study investigated the penetration of a 3g dose of C/T in the epithelial lining fluid (ELF) of ventilated patients with proven or suspected pneumonia. This is the dose and patient population being evaluated in ASPECT-NP. ELF lines the alveoli, and investigators took samples in a group of 26 patients to see what amount of C/T was in the lung and what was circulating in the plasma during the dosing intervals. In mechanically ventilated critically ill patients, the 3g dose of C/T achieved ≥50% lung penetration (relative to free plasma) and sustained levels in ELF above the target concentrations for the entire dosing interval. These findings support the 3g dose that is included in the ASPECT-NP Phase 3 trial.

Response: My clinical research interests revolve around critical care analgesia, sedation, and delirium. I validated the first delirium screening tool in mechanically ventilated ICU patients (published in 2001), described ICU delirium risk factors, associated outcomes, compared treatment modalities and described pharmacological exposure for the disorder. I was invited to participate in the 2013 Society of Critical Care Medicine Pain, Anxiety, and Delirium management guidelines, and served as the vice-chair for the recently completed Pain, Agitation, Delirium, Early Mobility and Sleep upcoming guidelines. Until this study, no pharmacological prevention or intervention could convincingly be considered effective in ICU delirium. Although Haloperidol and other antipsychotics are frequently used in practice, their lack of efficacy and possible disadvantages are increasingly being understood.

Rice, MD, MSc Associate Professor of Medicine Director, Vanderbilt University Hospital Medical Intensive Care Unit Division of Allergy, Pulmonary, and Critical Care Medicine Nashville, TN   Dr. Rice[/caption] Todd W. Rice, MD, MSc Associate Professor of Medicine Director, Vanderbilt University Hospital Medical Intensive Care Unit Division of Allergy, Pulmonary, and Critical Care Medicine Nashville, TN   MedicalResearch.com: What is the background for this study? Response: Our study (called the SMART study) evaluates the effects of different types of intravenous fluids used in practice in critically ill patients.  It is very similar to the companion study (called the SALT-ED study and published in the same issue) which compares the effects of different types of intravenous fluids on non-critically ill patients admitted to the hospital.  Saline is the most commonly used intravenous fluid in critically ill patients.  It contains higher levels of sodium and chloride than are present in the human blood.  Balanced fluids contain levels of sodium and chloride closer to those seen in human blood. Large observational studies and studies in animals have suggested that the higher sodium and chloride content in saline may cause or worsen damage to the kidney or cause death.  Only a few large studies have been done in humans and the results are a bit inconclusive.

Alban, MD FACS Associate Director Performance Improvement Associate Residency Program Director NSQIP Surgeon Champion Department of Surgery Cedars-Sinai Medical Center  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Continuous Renal Replacement Therapy (CRRT) is a modality of hemodialysis commonly used to manage renal failure in critically ill patients who have significant hemodynamic compromise.  However, it is also resource-intensive and costly and its usage is highly variable and lacks standardization. Our institution organized a multidisciplinary task force to target high value care in critically ill patients requiring CRRT by standardizing its process flow, promoting cross-disciplinary discussions with patients and family members, and increasing visibility/awareness of CRRT use.  After our interventions, the mean duration of CRRT decreased by 11.3% from 7.43 to 6.59 days per patient.  We also saw a 9.8% decrease in the mean direct cost of CRRT from $11642 to $10506 per patient.  Finally, we also saw a decrease in the proportion of patients expiring on CRRT, and an increase in the proportion of patients transitioning to comfort care.

MedicalResearch.com Interview with: “hospital.” by Bethany Satterfield is licensed under CC BY 2.0Mark van den Boogaard, PhD, RN, CCRN Assistant Professor Department of Intensive Care Medicine Radboud University Medical Center Nijmegen Netherlands  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Delirium is affecting many of our intensive care unit (ICU) patients which is impacting their recovery on the short-term as well as on the long-term. Therefore we were very interested to investigate if the use prophylactic haloperidol would be beneficial for the ICU patients. Especially because there were indications that it would be effective in ICU delirium prevention and also because this drug is being used in daily practice to prevent ICU delirium although there is no clear evidence. The overall finding of our large-scale well designed study is that we didn’t find any beneficial effect of prophylactic haloperidol in ICU patients. Moreover, this finding is very consistent over all groups of patients.

Response: One of the most pressing challenges facing medicine today is the emergence of bacterial resistance to antibiotics. One area of high concern is the increasing prevalence of resistance to powerful antibiotics like carbapenems, as patients with infections due to carbapenem-resistant bacteria have very few alternate effective treatment options. In this study we used real-world data from a Becton, Dickinson and Company electronic research data set to analyze over 140,000 bacterial isolates from patients at 342 hospitals across the United States, so that we could investigate where the burden of carbapenem resistance is most acute. Importantly analysis of real-world data in this way allows us to gain insights from a large number of hospitals, giving a broad and nationally representative picture of the resistance burden.

MedicalResearch.com Interview with: Marleen Boerma MD Department of Emergency Medicine Elisabeth-Tweesteden Hospital Tilburg, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Unplanned Intensive Care Unit (ICU) admission has been used as a surrogate marker of adverse events, and is used by the Australian Council of Healthcare Accreditation as a reportable quality indicator. If we can identify independent variables predicting deterioration which require ICU transfer within 24 hours after emergency department (ED) admission, direct ICU admission should be considered. This may improve patient safety and reduce adverse events by appropriate disposition of patients presenting to the ED. This study shows that there were significantly more hypercapnia patients in the ICU admission group (n=17) compared to the non-ICU group (n=5)(p=0.028). There were significantly greater rates of tachypnea in septic patients (p=0.022) and low oxygen saturation for patients with pneumonia (p=0.045). The level of documentation of respiratory rate was poor.

MedicalResearch.com Interview with: [caption id="attachment_30866" align="alignleft" width="146"]Michelle Kho, PT, PhD</strong> Canada Research Chair in Critical Care Rehabilitation and Knowledge Translation Assistant Professor School of Rehabilitation Science McMaster University Dr. Michelle Kho[/caption] Michelle Kho, PT, PhD Canada Research Chair in Critical Care Rehabilitation and Knowledge Translation Assistant Professor School of Rehabilitation Science McMaster University MedicalResearch.com: What is the background for this study? Response: Patients who survive the ICU are at risk for muscle weakness and can experience physical functional disability lasting 5 to 8 years after the ICU. From a study conducted in Belgium, patients who were randomized to receive cycling after being in ICU for 2 weeks walked farther at ICU discharge than those who did not. Other research supported physiotherapy starting within days of starting mechanical ventilation to improve functional outcomes. Our CYCLE research program combines these 2 concepts – Can we start cycling very early in a patient’s ICU stay, and will this improve functional outcomes post-ICU?

Response: The study was based on our overall impression that ICU care is often delivered to patients who are unlikely to derive long-term benefit (based on their co-morbidities/severity of illness, etc.). However, what surprised us was the magnitude of this problem. Our study found more than half the patients in ICU at a major metropolitan acute-care hospital could have been cared for in less expensive and invasive settings.

Teno, MD, MS Department of Gerontology and Geriatrics, Cambia Palliative Care Center of Excellence University of Washington Medicine Seattle, Washington Dr. Joan Teno[/caption] Joan M. Teno, MD, MS Department of Gerontology and Geriatrics, Cambia Palliative Care Center of Excellence University of Washington Medicine Seattle, Washington MedicalResearch.com: What is the background for this study? Response: An important challenge for our health care system is effectively caring for persons that high-need, high-cost — persons afflicted with advanced dementia and severe functional impairment are among these persons, with substantial need and if hospitalized in the ICU and mechanically ventilated are high cost patients, who are unlikely to benefit from this level of care and our best evidence suggest the vast majority of persons would not want this care. In a previous study, we interviewed families of advance dementia with 96% starting the goals of care are to focus comfort. Mechanical ventilation in some cases may be life saving, but in cases such as those with advanced dementia and severe functional impairment, they may result in suffering without an improvement in survival.
