Severe sepsis is common and presents a major challenge for clinicians, managers, and healthcare policymakers. Intensive care unit admissions meeting severe sepsis criteria have a high mortality rate and high resource use.
SummaryThis study sought to determine whether using the Resuscitation Council UK's iResus Ó application on a smart phone improves the performance of doctors trained in advanced life support in a simulated emergency. Thirty-one doctors (advanced life support-trained within the previous 48 months) were recruited. All received identical training using the smart phone and the iResus application. The participants were randomly assigned to a control group (no smart phone) and a test group (access to iResus on smart phone). Both groups were tested using a validated extended cardiac arrest simulation test (CASTest) scoring system. The primary outcome measure was the overall cardiac arrest simulation test score; these were significantly higher in the smart phone group ( Every year, approximately 30 000 people in the UK have an unexpected cardiac arrest in hospital. Despite significant advances in resuscitation research, survival to hospital discharge following cardiac arrest in adults remains poor [1]. The survival benefit of wellperformed cardiopulmonary resuscitation (CPR) is well documented. Recent evidence from both resuscitation training and in-hospital cardiac arrest suggests that CPR quality is suboptimal [2,3].Human factors affect the quality of CPR and disparity exists between resuscitation theory and its practical application -even experienced teams often perform sub-optimally in simulated resuscitation scenarios [4]. Possible explanations for this include the high-stress environment resulting in poor leadership behaviour, failure to delegate tasks explicitly, poor recall of knowledge and inevitable skill decay [5][6][7].
Summary
A telephone survey was carried out on the use of hypothermia as part of the management of unconscious patients following cardiac arrest admitted to United Kingdom (UK) intensive care units (ICUs). All 256 UK ICUs listed in the Critical Care Services Manual 2004 were contacted to determine how many units have implemented therapeutic hypothermia for unconscious patients admitted following cardiac arrest, how it is implemented, and the reasons for non‐implementation. Two hundred and forty‐six (98.4%) ICUs agreed to participate. Sixty‐seven (28.4%) ICUs have cooled patients after cardiac arrest, although the majority of these have treated fewer than 10 patients. The commonest reasons given for not using therapeutic hypothermia in this situation are logistical or resource issues, or the perceived lack of evidence or consensus within individual ICU teams.
SummaryThis study surveyed current practice in adult intensive care units in the United Kingdom in three key areas of renal replacement therapy when used for acute renal failure: type of therapy used, typical treatment dose and anticoagulation.
There is a growing awareness amongst critical care practitioners that the impact of intensive care medicine extends beyond the patient to include the psychological impact on close family members. Several studies have addressed the needs of relatives within the intensive care context but the psychobiological impact of the experience has largely been ignored. Such impact is important in respect to health and well-being of the relative, with potential to influence patient recovery. The current feasibility study aimed to examine the acute psychobiological impact of the intensive care experience on relatives. Using a mixed methods approach, quantitative and qualitative data were collected simultaneously. Six relatives of patients admitted to the intensive care unit (ICU) of a District General Hospital, were assessed within 48 h of admission. Qualitative data were provided from semi-structured interviews analysed using interpretative phenomenological analysis. Quantitative data were collected using a range of standardised self-report questionnaires measuring coping responses, emotion, trauma symptoms and social support, and through sampling of diurnal salivary cortisol as a biomarker of stress. Four themes were identified from interview: the ICU environment, emotional responses, family relationships and support. Questionnaires identified high levels of anxiety, depression and trauma symptoms; the most commonly utilised coping techniques were acceptance, seeking support through advice and information, and substance use. Social support emerged as a key factor with focused inner circle support relating to family and ICU staff. Depressed mood and avoidance were linked to greater mean cortisol levels across the day. Greater social network and coping via self-distraction were related to lower evening cortisol, indicating them as protective factors in the ICU context. The experience of ICU has a psychological and physiological impact on relatives, suggesting the importance of identifying cost-effective interventions with evaluations of health benefits to both relatives and patients.
Intensive insulin therapy to control blood glucose has been found to reduce mortality among critically ill patients in a surgical intensive care unit, though a simple prescriptive insulin infusion protocol to achieve this has not been published previously. This study documents the development and routine use of a simple prescriptive intravenous insulin infusion protocol for critically ill patients and compares the results with previous practice. During development the protocol was optimized and practical issues of implementation addressed. The optimized protocol was then used for all ICU admissions, and a prospectively defined retrospective chart audit performed for the first month of use. Results were compared with a similar time period the previous year. In September 2002, 27 admissions were started on the protocol. Blood glucose for the time on the protocol had a median value of 6.2 (IQR 5.9-7.1) mmol/l compared with 9. 2 (IQR 8.1-10.2) mmol/l for those on insulin in 2001. Blood glucose for the whole ICU stay for those on the protocol in 2002 had a median value of 6.6 (IQR 6.0-7.4) mmol/l compared with 8.6 (IQR 8.0-9.4) mmol/l in 2001. Blood glucose for all ICU patients in 2002
) mmol/l in 2001.Three blood glucose recordings were less than 2.2 mmol/l in September 2002. This study provides initial effectiveness and safety data for the Bath Insulin Protocol. Further audits in a larger patient population are now needed.
