Critical care without walls

Emergency critical care: closing the gap between onset of critical illness and intensive care unit admission

Critical illness is an exquisitely time-sensitive condition and follows a disease continuum, which always starts before admission to the intensive care unit (ICU), in the majority of cases even before hospital admission. Reflecting the common practice in many healthcare systems that critical care is mainly provided in the confined areas of an ICU, any delay in ICU admission of critically ill patients is associated with increased morbidity and mortality. However, if appropriate critical care interventions are provided before ICU admission, this association is not observed. Emergency critical care refers to critical care provided outside of the ICU. It encompasses the delivery of critical care interventions to and monitoring of patients at the place and time closest to the onset of critical illness as well as during transfer to the ICU. Thus, emergency critical care covers the most time-sensitive phase of critical illness and constitutes one missing link in the chain of survival of the critically ill patient. Emergency critical care is delivered whenever and wherever critical illness occurs such as in the pre-hospital setting, before and during inter-hospital transfers of critically ill patients, in the emergency department, in the operating theatres, and on hospital wards. By closing the management gap between onset of critical illness and ICU admission, emergency critical care improves patient safety and can avoid early deaths, reverse mild-to-moderate critical illness, avoid ICU admission, attenuate the severity of organ dysfunction, shorten ICU length of stay, and reduce short- and long-term mortality of critically ill patients. Future research is needed to identify effective models to implement emergency critical care systems in different healthcare systems.

Safety and Effectiveness of Intensive Treatments Administered Outside the Intensive Care Unit to Hematological Critically Ill Patients: An Intensive Care without Walls Trial

Historically, the admission of hematological patients in the ICU shortly after the start of a critical illness is associated with better survival rates. Early intensive interventions administered by MET could play a role in the management of hematological critically ill patients, eventually reducing the ICU admission rate. In this retrospective and monocentric study, we evaluate the safety and effectiveness of intensive treatments administered by the MET in a medical ward frame. The administered interventions were mainly helmet CPAP and pharmacological cardiovascular support. Frequent reassessment by the MET at least every 8 to 12 h was guaranteed. We analyzed data from 133 hematological patients who required MET intervention. In-hospital mortality was 38%; mortality does not increase in patients not immediately transferred to the ICU. Only three patients died without a former admission to the ICU; in these cases, mortality was not related to the acute illness. Moreover, 37% of patients overcame the critical episode in the hematological ward. Higher SOFA and MEWS scores were associated with a worse survival rate, while neutropenia and pharmacological immunosuppression were not. The MET approach seems to be safe and effective. SOFA and MEWS were confirmed to be effective tools for prognostication.

Systematized and efficient: organization of critical care in the future

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.

Protocol for a systematic review on effective patient positioning for rapid sequence intubation

INTRODUCTION

Rapid sequence intubation (RSI) is an advanced airway technique to perform endotracheal intubation in patients at high risk of aspiration. Although RSI is recognised as a life-saving technique and performed by many physicians in various settings (emergency departments, intensive care units), there is still a lack of consensus on various features of the procedure, most notably patient positioning. Previously, experts have commented on the unique drawbacks and benefits of various positions and studies have been published comparing patient positions and how it can affect endotracheal intubation in the context of RSI. The purpose of this systematic review is to compile the existing evidence to understand and compare how different patient positions can potentially affect the success of RSI.

METHODS AND ANALYSIS

We will use MEDLINE, EMBASE and the Cochrane Library to source studies from 1946 to 2021 that evaluate the impact of patient positioning on endotracheal intubation in the context of RSI. We will include randomised control trials, case-control studies, prospective/retrospective cohort studies and mannequin simulation studies for consideration in this systematic review. Subsequently, we will generate a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram to display how we selected our final studies for inclusion in the review. Two independent reviewers will complete the study screening, selection and extraction, with a third reviewer available to address any conflicts. The reviewers will extract this data in accordance with our outcomes of interest and display it in a table format to highlight patient-relevant outcomes and difficulty airway management outcomes. We will use the Risk of Bias tool and the Newcastle-Ottawa Scale to assess included studies for bias.

ETHICS AND DISSEMINATION

This systematic review does not require ethics approval, as all patient-centred data will be reported from published studies.

Socio-demographic characteristics and pre-hospital care of children with circulatory failure in a children's emergency room in southern Nigeria

Introduction

circulatory failure is a major childhood emergency. Several disease-related and patient-related factors can predispose children to shock. Early detection of such factors will improve its prevention, management and outcome. This study aimed to evaluate the incidence, socio-demographic characteristics and pre-hospital care of children presenting with circulatory failure (shock) in children´s emergency room (CHER).

Methods

this study adopted cross-sectional design in CHER of the University of Benin Teaching Hospital, Nigeria, from October 2018 to March 2019. Data were collected using a semi-structured questionnaire eliciting demography, socio-economic status, pre-hospital care and presence of shock. In a sub-analysis, multiple logistic regression identified variables that are independently associated with circulatory failure in the participants, using adjusted odds ratio (OR) and 95% confidence intervals (CI).

Results

a total of 554 acutely-ill children participated in the study. Their median age was 60 (IQR: 24-132) months. Shock was present in 79 (14.3%) of the children on arrival at CHER. Children referred from private clinics were more likely to arrive CHER in shock compared to those coming directly from home (OR = 2.67, 95%CI: 1.07-6.69; p = 0.036) while children from lower socio-economic class families presented more frequently with shock than those from higher class (OR = 14.39, 95% CI: 2.61-79.44; p = 0.002). Also, children that received oral rehydration solution as pre-hospital care seemed more likely to present with shock in CHER (OR = 6.63, 95% CI: 2.15-20.46; p =0.001).

Conclusion

quality of pre-hospital care and parental socio-economic status influence the presence of shock in children seen at the emergency unit. Focused health education and prevention of finance-related delays in emergency care are needed.

Adaptation and restructuring of an academic anesthesiology department during the COVID-19 pandemic in New York City: Challenges and lessons learned

The novel SARS-CoV-2 pandemic starting in 2019 profoundly changed the world, and thousands of residents of New York City were affected, leading to one of the most acute surges in regional hospital capacity. As the largest academic medical center in the Bronx, Montefiore Medical Center was immediately impacted, and the entire hospital was mobilized to address the needs of its community. In this article, we describe our experiences as a large academic anesthesiology department during this pandemic. Our goals were to maximize our staff's expertise, maintain our commitment to wellness and safety, and preserve the quality of patient care. Lessons learned include the importance of critical care training presence and leadership, the challenges of converting an ambulatory surgery center to an intensive care unit (ICU), and the management of effective communication. Lastly, we provide suggestions for institutions facing an acute surge, or subsequent waves of COVID-19, based on a single center's experiences.

Rapid sequence induction: where did the consensus go?

Background

Rapid Sequence Induction (RSI) was introduced to minimise the risk of aspiration of gastric contents during emergency tracheal intubation. It consisted of induction with the use of thiopentone and suxamethonium with the application of cricoid pressure.

This narrative review describes how traditional RSI has been modified in the UK and elsewhere, aiming to deliver safe and effective emergency anaesthesia outside the operating room environment. Most of the key aspects of traditional RSI – training, technique, drugs and equipment have been challenged and often significantly changed since the procedure was first described. Alterations have been made to improve the safety and quality of the intervention while retaining the principles of rapidly securing a definitive airway and avoiding gastric aspiration. RSI is no longer achieved by an anaesthetist alone and can be delivered safely in a variety of settings, including in the pre-hospital environment.

Conclusion

The conduct of RSI in current emergency practice is far removed from the original descriptions of the procedure. Despite this, the principles – rapid delivery of a definitive airway and avoiding aspiration, are still highly relevant and the indications for RSI remain relatively unchanged.

Critical emergency medicine and the resuscitative care unit

Critical emergency medicine is the medical field concerned with management of critically ill patients in the emergency department (ED). Increased ED stay due to intensive care unit (ICU) overcrowding has a negative impact on patient care and outcome. It has been proposed that implementation of critical care services in the ED can negate this effect. Two main Critical Emergency Medicine models have been proposed, the "resource intensivist" and "ED-ICU" models. The resource intensivist model is based on constant presence of an intensivist in the traditional ED setting, while the ED-ICU model encompasses the notion of a separate ED-based unit, with monitoring and therapeutic capabilities similar to those of an ICU. Critical emergency medicine has the potential to improve patient care and outcome; however, establishment of evidence-based protocols and a multidisciplinary approach in patient management are of major importance.

Appropriateness of antimicrobial use among septic patients managed by the critical care response team: an opportunity for improvement through de-escalation

Background

Most septic patients managed by critical care response teams (CCRT) are prescribed antimicrobials. Nevertheless, data evaluating their appropriateness are lacking both locally and internationally. The objective was to assess antimicrobial use among septic and non-septic patients managed by CCRT.

Setting

Case-control design was used to compare septic (cases) and non-septic (controls) CCRT patients at tertiary care setting. The frequency of antimicrobial use was assessed before and after CCRT activation. The appropriateness of antimicrobial use was assessed at day four post-CCRT, based on standard recommendations, clinical assessment, and culture results.

Main results

A total of 157 cases and 158 controls were included. The average age was 61.1 ± 20.4 years, and 54.6% were males, with minor differences between groups. The use of any antimicrobial was 100.0% in cases and 87.3% in controls (p < 0.001). The use of meropenem (68.2% versus 34.8%, p < 0.001) and vancomycin (56.7% versus 25.9%, p < 0.001) were markedly higher in cases than controls. The overall appropriateness was significantly lower in cases than controls (50.7% versus 59.6%, p = 0.047). Individual appropriateness was lowest with meropenem (16.7%) and imipenem (25.0%), and highest with piperacillin/tazobactam (87.1%) and colistin (78.3%). Only 48.5% of antimicrobials prescribed by CCRT were de-escalated by a primary team within four days. Individual appropriateness and de-escalations were not different between groups.

Conclusions

Empiric use and inadequate de-escalation of broad-spectrum antimicrobials were major causes for inappropriate antimicrobial use in CCRT patients. Our findings highlight the necessity of urgent implementation of an antimicrobial stewardship program, including training and auditing of antimicrobial prescriptions.

Assessment of various aspects of using protocols in intensive care units in Plovdiv, Bulgaria

Background: Since 1950 intensive care has become a separate and independent specialty. Significant technological advances have allowed the Intensive Care Unit (ICU)s to be monitored through the centralized work of a multidisciplinary team of specialists. ICUs provide cares at different levels of support. To provide patient access to this highly specialized cares, the “Critical care without walls” or “Intensive Care without Borders” theories have emerged, involving reanimation nurses offering highly specialized care and support. Protocols for nurses have been developed, with the aim of facilitating their day-to-day activities, improving outcomes and safety of patients and all staff. Utilizing this concept, the role of intensive care has rapidly expanded over the past 20 years. Aim of the study: To understand the effectiveness and benefits derived from organisation of the working process. Material and methods: We used documentary and survey methods and analysed the data using the software package SPSS v. 21.0. Graphics were prepared using Microsoft Excel 2013. Numbers from 1 to 5 refer to the answers “no”, “not really”, “cannot judge”, “closer to yes” and “yes”, respectively. Results: Nurses’ performance, as an integral part of multidisciplinary ICU teams, is evidence that mortality and morbidity can be improved thanks to the early recognition of patient deterioration and rapid resuscitation. The better healing process is accomplished by optimising the content and evaluation of the desired results, in association with good doctor practices. Respondents’ opinions about outcomes of protocol use differed significantly between professions in regard to making their job easier, improving patient outcomes, providing consistency in care, and preventing patient harm. Conclusions: A more flexible and standard framework for nurses should be developed to improve quality of care. The rapidly growing lack of ICU nurses in Bulgaria is concerning.

Staffing and workforce issues in the pediatric intensive care unit

The health care industry is in the midst of incredible change, and unfortunately, change is not easy. The intensive care unit (ICU) plays a critical role in the overall delivery of care to patients in the hospital. Care in the ICU is expensive. One of the best ways of improving the value of care delivered in the ICU is to focus greater attention on the needs of the critical care workforce. Herein, we highlight three major areas of concern-the changing model of care delivery outside of the traditional four walls of the ICU, the need for greater diversity in the pediatric critical care workforce, and the widespread problem of professional burnout and its impact on patient care.

Understanding how medications contribute to clinical deterioration and are used in rapid response systems: A comprehensive scoping review

BACKGROUND

In hospitals, rapid response systems (RRSs) identify patients who deteriorate and provide critical care at their bedsides to stabilise and escalate care. Medications, including oral and parenteral pharmaceutical preparations, are the most common intervention for hospitalised patients and the most common cause of harm. This connection between clinical deterioration and medication safety is poorly understood.

OBJECTIVES

To inform improvements in prevention and management of clinical deterioration, this review aimed to examine how medications contributed to clinical deterioration and how medications were used in RRSs.

REVIEW METHODS

A scoping review was undertaken of medication data reported in studies of clinical deterioration or RRSs in diverse hospital settings between 2005 and 2017. Bibliographic database searches used permutations of "rapid response system," "medical emergency team," and keyword searching with medication-related terms. Independent selection, quality assessment, and data extraction informed mapping against four medication themes: causes of deterioration, predictors of deterioration, RRS use, and management.

RESULTS

Thirty articles were reviewed. Quality was low: limited by small samples, observational, single-centre designs and few primary medication-related outcomes. Adverse drug reactions and potentially preventable medication errors, involving sedatives, analgesics, and cardiovascular agents, contributed to clinical deterioration. While sparsely reported, outcomes included death and escalation of care. In children, administration of antibiotics or nebulised medications appeared to predict subsequent deterioration. Cardiovascular medications, sedatives, and analgesics commonly were used to manage deterioration but further detail was lacking. Despite reported potential for patient harm, evaluation of medication management systems was limited.

CONCLUSIONS

Medications contributed to potentially preventable clinical deterioration, with considerable harm, and were common interventions for its management. When assessing deteriorating patients or caring for patients who require escalation to critical care, clinicians should consider medication errors and adverse reactions. Studies with more specific medication-related, patient-centred end points could reduce medication-related deterioration and refine RRS medication use and management.

Research questions in pre-hospital trauma care

Noting that a variety of pre-hospital interventions can now be applied to treat traumatic injury, David J Lockey calls for research to determine which of these actually improve survival and reduce morbidity.

Impact on patient outcome of emergency department length of stay prior to ICU admission

OBJECTIVE

The favorable evolution of critically ill patients is often dependent on time-sensitive care intervention. The timing of transfer to the intensive care unit (ICU) therefore may be an important determinant of outcomes in critically ill patients. The aim of this study was to analyze the impact upon patient outcome of the length of stay in the Emergency Care Department.

DESIGN

A single-center ambispective cohort study was carried out.

SETTING

A general ICU and Emergency Care Department (ED) of a single University Hospital.

PATIENTS

We included 269 patients consecutively transferred to the ICU from the ED over an 18-month period.

INTERVENTIONS

Patients were first grouped into different cohorts based on ED length of stay (LOS), and were then divided into two groups: (a) ED LOS ≤5h and (b) ED LOS >5h.

VARIABLES

Demographic, diagnostic, length of stay and mortality data were compared among the groups.

RESULTS

Median ED LOS was 277min (IQR 129-622). Patients who developed ICU complications had a longer ED LOS compared to those who did not (349min vs. 209min, p<0.01). A total of 129 patients (48%) had ED LOS >5h. The odds ratio of dying for patients with ED LOS >5h was 2.5 (95% CI 1.3-4.7). Age and sepsis diagnosis were the risk factors associated to prolongation of ED length of stay.

CONCLUSIONS

A prolonged ED stay prior to ICU admission is related to the development of time-dependent complications and increased mortality. These findings suggest possible benefit from earlier ICU transfer and the prompt initiation of organ support.

Do not resuscitate: An expanding role for critical care response team

BACKGROUND

Do not resuscitate (DNR) order is an important aspect of medical practice. Since the implementation of critical care response team (CCRT), frequently we have encountered with patients in the wards that should have been made DNR. Initiating DNR became an important part of CCRT activity. We were obliged to extended the role of CCRT - beyond managing seriously ill patients - in addressing the code status for patients after discussion with the managing teams.

PURPOSE

We compare the trend of initiation of DNR orders in the regular ward before and after implementing CCRT.

METHODS

Our hospital is 1200 bed tertiary care center. CCRT has been launched in January 1, 2008. The CCRT is 24/7 service led by in-house North American certified intensivists. Cohort analysis of prospectively collected data of 5406 CCRT activation from January 1, 2008, to September 30, 2013. Data before implementation of CCRT was available for 299 patients from the period of June 1, 2007, to December 31, 2007. A comparison made between the two groups (before and after implementation of CCRT) for demographic data and percentage of patients in whom DNR order initiated.

RESULTS

Before CCRT implementation, 299 patients were attended by Intensive Care Unit physician for regular consultation, 41.1% were females and 52.4% were males with mean of age 58.44 ± 18.47 standard deviation (SD). DNR was initiated in 2.7% of patients. After CCRT implementation, 5904 CCRT activations, 47.6% females and 52.4% males with mean of age 59.17 ± 20.07 SD DNR initiated in 468 (7.9%) of cases. There was 5.2% increase in DNR orders initiation and completion after CCRT introduced to our institute.

The critical care/acute medicine interphase

A significant number of medical admissions and inpatients on general wards are unstable or have unmet medical or nursing needs. Ward-based physiological scoring (early warning scores) and similar innovations aim to identify those who may merit enhanced care, and initiatives such as 'comprehensive critical care' describe a whole system approach to this group. While the recommendations in this 15-year-old document have been largely accepted and implemented, the Future Hospital Report recognises that close cooperation between acute medicine and critical care is essential but lacking in many institutions. Much of what follows is opinion and conjecture as there is little hard data to refer to. Although an anaesthetically trained intensivist, I have been a member of the Society for Acute Medicine since its inception and have sat on Council since then as critical care representative. I was also the clinical director for acute medicine in Norwich for three years.

Surveillance of Patients in the Waiting Area of the Department of Emergency Medicine

Many patients visiting an emergency department are in reduced general condition of health and at risk of suffering further deterioration during their stay. We wanted to test the feasibility of a new monitoring system in a waiting area of an emergency department.In an observational cross-sectional single-center study, patients with acute cardiac or pulmonary symptoms or in potentially life-threatening conditions were enrolled. Monitoring devices providing vital signs via short range radio (SRR) at certain time points and compliance evaluation forms were used.Out of 230 patients, 4 wanted to terminate their participation prematurely. No data was lost due to technical difficulties. Over a median monitoring period of 178 (118-258) min per patient, 684 h of vital sign data were collected and used to assist managing those patients. Linear regression analysis between clinical symptom category groups of patients showed significant differences in the respiratory rate and noninvasive blood pressure courses. Feedback from patients and users via questionnaires showed overall very good acceptance and patients felt that they were given better care.To assist medical staff of an emergency department waiting area to rapidly response to potentially life-threatening situations of its patients, a new monitoring system proved to be feasible and safe.

Pre-hospital anaesthesia: the same but different

Advanced airway management is one of the most controversial areas of pre-hospital trauma care and is carried out by different providers using different techniques in different Emergency Medical Services systems. Pre-hospital anaesthesia is the standard of care for trauma patients arriving in the emergency department with airway compromise. A small proportion of severely injured patients who cannot be managed with basic airway management require pre-hospital anaesthesia to avoid death or hypoxic brain injury. The evidence base for advanced airway management is inconsistent, contradictory and rarely reports all key data. There is evidence that poorly performed advanced airway management is harmful and that less-experienced providers have higher intubation failure rates and complication rates. International guidelines carry many common messages about the system requirements for the practice of advanced airway management. Pre-hospital rapid sequence induction (RSI) should be practiced to the same standard as emergency department RSI. Many in-hospital standards such as monitoring, equipment, and provider competence can be achieved. Pre-hospital and emergency in-hospital RSI has been modified from standard RSI techniques to improve patient safety, physiological disturbance, and practicality. Examples include the use of opioids and long-acting neuromuscular blocking agents, ventilation before intubation, and the early release of cricoid pressure to improve laryngoscopic view. Pre-hospital RSI is indicated in a small proportion of trauma patients. Where pre-hospital anaesthesia cannot be carried out to a high standard by competent providers, excellent quality basic airway management should be the mainstay of management.

Should resuscitative thoracotomy be performed in the pre-hospital phase of care?

Penetrating thoracic trauma is increasing in the UK and elsewhere and immediate transfer to a Major Trauma Centre with cardio-thoracic expertise is usually optimal management. Pre-hospital traumatic cardiac arrest has an extremely poor prognosis. Performing thoracotomy before arrival in hospital has produced neurologically intact survivors in several case series. The technique described involves rapid clamshell thoracotomy and release of pericardial tamponade. Favourable outcomes appear to be associated with a single stab wound to the heart causing cardiac tamponade. Pre-hospital thoracotomy is described in the current European Resuscitation Guidelines and courses for non-surgeons are now taught at the Royal College of Surgeons of England and at the Surgical Skills Training Centre at Newcastle Freeman Hospital. It is likely that further survivors will be reported as the technique becomes more widely used. Alternatives to pre-hospital thoracotomy in the future for patients with hypovolaemic cardiac arrest may include resuscitative endovascular balloon occlusion of the aorta and pre-hospital extended preservation and resuscitation.

Practical translation of hemorrhage control techniques to the civilian trauma scene

This article examines how established and innovative techniques in hemorrhage control can be practically applied in a civilian physician-based prehospital trauma service. A "care bundle" of measures to control hemorrhage on scene are described. Interventions discussed include the implementation of a system to achieve simple endpoints such as shorter scene times, appropriate triage, careful patient handling, use of effective splints and measures to control external hemorrhage. More complex interventions include prehospital activation of massive hemorrhage protocols and administration of on-scene tranexamic acid, prothrombin complex concentrate, and red blood cells. Radical resuscitation interventions, such as prehospital thoracotomy for cardiac tamponade, and the potential future role of other interventions are also considered.

An observational study to determine the effect of delayed admission to the intensive care unit on patient outcome

INTRODUCTION

Delayed patient admission to the intensive care unit (ICU) due to lack of bed availability is a common problem, but the effect on patient outcome is not fully known.

METHODS

A retrospective study was performed using departmental computerised records to determine the effect of delayed ICU admission and temporary management within the operating theatre suite on patient outcome. Emergency surgical and medical patients admitted to the ICU (2003 to 2007) were divided into delay (more than three hours from referral to admission) and no-delay (three or fewer hours from referral to admission) groups. Our primary outcome measure was length of ICU stay. Secondary outcome measures were mortality rates and duration of organ support.

RESULTS

A total of 1,609 eligible patients were included and 149 (9.3%) had a delayed admission. The delay and no-delay groups had similar baseline characteristics. Median ICU stay was 5.1 days (delay) and 4.5 days (no-delay) (P = 0.55) and ICU mortality was 26.8% (delay) and 24.2% (no-delay) (P = 0.47). Following adjustment for demographic and baseline characteristics there was no difference in either length of ICU stay or mortality rates between groups. ICU admission delay was associated with both an increased requirement for advanced respiratory support (92.3% delay vs. 76.4% no-delay, P <0.01) and a longer time spent ventilated (median four days delay vs. three days no-delay, P = 0.04).

CONCLUSIONS

No significant difference in length of ICU stay or mortality rate was demonstrated between the delay and no-delay cohorts. Patients within the delay group had a significantly greater requirement for advanced respiratory support and spent a longer time ventilated.

Once more unto the breach, dear friends, once more

The first issue of the World Journal of Critical Care Medicine (WJCCM), whose preparatory work was initiated on December 16, 2010, will be published on February 4, 2012. The WJCCM Editorial Board has now been established and consists of 105 distinguished experts from 27 countries. Our purpose of launching the WJCCM is to publish peer-reviewed, high-quality articles via an open-access online publishing model, thereby acting as a platform for communication between peers and the wider public, and maximizing the benefits to editorial board members, authors and readers.

Severe sepsis: take care, take part

Severe sepsis is defined as organ dysfunction in the setting of systemic inflammatory response due to infection. With changes in population age, comorbidity and the delivery of medical care, severe sepsis is increasingly common, and can present in every area of the hospital. The major obstacles to improved outcomes in severe sepsis are deficiencies in healthcare staffing and education, haphazard recognition and response to early clinical deterioration and deviation from optimal management as defined by international guidelines. Major treatment errors were identified in 30% of patients with bacteraemia in one recent investigation. Against this, substantial reductions in mortality can be achieved by improving recognition, urgent care and resuscitation. With a view to improving survival in sepsis, collaborative efforts are required to measure outcomes, implement guidelines and secure adequate funding for ongoing practice improvement, education and research.

Continuum of hospital care: the role of intensive care

PURPOSE OF REVIEW

This review outlines the way the specialty of intensive care has expanded over the last decade in response to the changing population of hospital patients, being older with more comorbidities and having more complex interventions. The previous disjointed professional and geographical silos, providing patient care, are being challenged and a more patient focussed continuum of care is replacing it.

RECENT FINDINGS

There have been many reports over the last few years, describing patient centred systems, constructed around the needs of the seriously ill, at-risk patient, including trauma systems and Medical Emergency Team-type systems. There is now general agreement that in most settings these systems are responsible for a significant reduction in mortality and serious adverse events such as cardiac arrest rates.

SUMMARY

The implications for the move towards systems to improve patient outcome and decrease mortality in hospitals are having a significant impact on the way we practise medicine, resulting in an emphasis, among other things, of constructing our care around the needs of patients, rather than rigidly practice medicine from within our own tribal boundaries, for example professional boundaries, medical specialty boundaries and geographical boundaries.

Intensive Care Medicine: Where We Are and Where We Want To Go?

Intensive care medicine can be defined as the science and art of detecting and managing patients with impending or established critical illness, in order to prevent further deterioration and revert the disease process or its consequences, so as to achieve the best possible outcomes.

Critical care: advances and future perspectives

Intensive care offers a standard of monitoring, intervention, and organ support that cannot be readily delivered in a general ward. Its expansion in the past few decades, including the creation of emergency and outreach teams, emphasises that intensive care has an increasingly prominent role within the hospital. Although outcomes are clearly improving, intensive care remains a nascent specialty in which we are still learning how to harness a powerful ability to manipulate physiology, biochemistry, and immunology to achieve best outcomes for the patient. The results of many multicentre studies have not lent support to, or have even confounded, expectations, drawing attention to several issues related to patient heterogeneity, trial design, and elucidation of underlying pathophysiological processes. However, these results have generated constructive introspection and reappraisal of treatments and management strategies that have benefited the patient. In addition to the medical, financial, and logistical challenges in the future, exciting opportunities will arise as new developments in diagnostic tests, therapeutic interventions, and technology are used to exploit an increasing awareness of how critical illness should be managed.

'Not quite Jericho, but more doors than there used to be'. Staff views of the impact of 'modernization' on boundaries around adult critical care services in England

OBJECTIVES

To explore staff perceptions of the impact of 'modernization' on the organization, delivery and culture of adult critical care services in England. 'Modernization' policies aimed to alter the boundaries around critical care and create a comprehensive, seamless service.

METHODS

Seven hospitals (three teaching and four district general hospitals) in three critical care networks participated. In-depth interviews were conducted with a purposive sample of 45 critical care staff. Data were analysed thematically.

RESULTS

The boundaries around critical care were generally perceived to be less fixed than previously. The re-framing of 'internal walls' within hospitals was associated with the introduction of outreach teams, new hospital-wide remits for intensive care unit (ICU) staff and the greater integration of allied health professionals into the critical care team. Transformation of services was challenged by practicalities including the need for additional staff, and a 'them and us' attitude between ICU and ward staff. 'External walls' between hospitals were breached where local clinical networks were perceived to have successfully improved communication and joint working. This was facilitated by effective leadership, availability of network-associated funds, the identification of common problems and evidence of benefit from cooperation. However, barriers existed and there was some scepticism among staff as to whether critical care can ever be entirely 'without walls'.

CONCLUSIONS

Policies to remove boundaries around adult critical care are perceived to have had a dramatic impact on the organization of the service. Considerable progress was reported towards developing comprehensive critical care services both within and between hospitals.

A 'shock room' for early management of the acutely ill

Our 850-bed, academic, tertiary care hospital uses a four-bed dedicated 'shock room' situated between the Departments of Emergency Medicine and Intensive Care to stabilise all acutely ill patients from outside or inside the hospital before transfer to the intensive care unit or other department. Admitted patients stay a maximum of four hours in the shock room. In this article we describe our experiences using this shock room by detailing the demographic data, including time and source of admission, diagnosis and outcome, for the 2514 patients admitted to the shock room in 2006. The most common reasons for admission were cardiac (33%) and neurological (21%) diagnoses. After diagnosis and initial treatment, 54% of patients were transferred to an intensive care unit or a coronary care unit; 2.5% of patients died in the shock room. The shock room provides a useful area of collaboration between emergency department and intensive care unit staff and enables acutely ill patients to be assessed and treated rapidly to optimise outcomes.

Critical care services in Ontario: a survey-based assessment of current and future resource needs

PURPOSE

In response to the challenges of an aging population and decreasing workforce, the provision of critical care services has been a target for quality and efficiency improvement efforts. Reliable data on available critical care resources is a necessary first step in informing these efforts. We sought to describe the availability of critical care resources, forecast the future requirement for the highest-level critical care beds and to determine the physician management models in critical care units in Ontario, Canada.

METHODS

In June 2006, self-administered questionnaires were mailed to the Chief Executive Officers of all acute care hospitals, identified through the Ontario government's hospital database. The questionnaire solicited information on the number and type of critical care units, number of beds, technological resources and management of each unit.

RESULTS

Responses were obtained from 174 (100%) hospitals, with 126 (73%) reporting one or more critical care units. We identified 213 critical care units in the province, representing 1789 critical care beds. Over half (59%) of these beds provided mechanical ventilation on a regular basis, representing a capacity of 14.9 critical care and 8.7 mechanically ventilated beds per 100,000 population. Sixty-three percent of units with capacity for mechanical ventilation involved an intensivist in admission and coordination of care. Based on current utilization, the demand for mechanically ventilated beds by 2026 is forecast to increase by 57% over levels available in 2006. Assuming 80% bed utilization, it is estimated that an additional 810 ventilated beds will be needed by 2026.

CONCLUSION

Current utilization suggests a substantial increase in the need for the highest-level critical care beds over the next two decades. Our findings also indicate that non-intensivists direct care decisions in a large number of responding units. Unless major investments are made, significant improvements in efficiency will be required to maintain future access to these services.

Impact of critical care outreach services on the delivery and organization of hospital care

OBJECTIVES

To evaluate the impact of critical care outreach services on the delivery and organization of hospital care from the perspective of staff working in acute hospitals.

METHODS

One hundred semi-structured interviews were undertaken with hospital staff who were either members of, or who came into contact with, the outreach service in eight hospitals in England.

RESULTS

Outreach services had two main impacts on the delivery and organization of hospital care, reflecting the organizational and educational aims of the policy. First, on the organization of patient care: it was suggested that care was more timely, there were fewer referrals to the intensive care unit (ICU) and ICUs felt more able to discharge patients to hospital wards. There were also perceived to be improved links between ward nurses and medical teams and improved morale among ICU nurses. Second, on the confidence and skills of ward staff (nurses and junior doctors): increased contact on the wards resulted in more opportunities to share critical care skills. However, there remained concerns about the sustainability of improved skills and some respondents felt that junior doctors were becoming de-skilled.

CONCLUSION

Critical care outreach services have had a positive impact on the delivery and organization of hospital care. In attempting to share critical care skills, however, these services can experience a tension between the aims of service delivery and education - a tension which is partly resolved by sharing skills in the clinical and organizational context of direct patient care.
