We conducted an international survey of intensive care physicians in Australia, New Zealand (ANZ) and the United Kingdom (UK). The aims of the survey were to assess the current prescribing practice patterns, attitudes towards prescribing statin therapy in critically ill patients and opinions on the need for an interventional trial of statin therapy in critically ill patients. Methods: Survey questions were developed through an iterative process. An expert group reviewed the resulting 26 items for face and content validity and clarity. The questions were further refined following pilot testing by ICU physicians from Australia, Canada and the UK. We used the online Smart Survey software to administer the survey. Results: Of 239 respondents (62 from ANZ and 177 from UK) 58% worked in teaching hospitals; most (78.2%) practised in 'closed' units with a mixed medical and surgical case mix (71.0%). The most frequently prescribed statins were simvastatin (77.6%) in the UK and atorvastatin (66.1%) in ANZ. The main reasons cited to explain the choice of statin were pre-admission prescription and pharmacy availability. Most respondents reported never starting statins to prevent (65.3%) or treat (89.1%) organ dysfunction. Only a minority (10%) disagreed with a statement that the risks of major side effects of statins when prescribed in critically ill patients were low. The majority (84.5%) of respondents strongly agreed that a clinical trial of statins for prevention is needed. More than half (56.5%) favoured rates of organ failure as the primary outcome for such a trial, while a minority (40.6%) favoured mortality. Conclusions: Despite differences in type of statins prescribed, critical care physicians in the UK and ANZ reported similar prescription practices. Respondents from both communities agreed that a trial is needed to test whether statins can prevent the onset of new organ failure in patients with sepsis.

SMC accepts dexmedetomidine (Dexdor®) for sedation in adult intensive care unit (ICU) patients Source: Scottish Medicines Consortium (SMC) Date published: 12/06/2012 14:42 Summary by: Hina Radia The Scottish Medicines Consortium (SMC) has accepted dexmedetomidine (Dexdor®) for use within NHS Scotland for sedation in adult intensive care unit (ICU) patients requiring a sedation level not deeper than arousal in response to verbal stimulation (corresponding to Richmond Agitation-Sedation Scale [RASS] 0 to -3). The Committee noted that dexmedetomidine was as effective as propofol and midazolam in maintaining the target depth of sedation in ICU patients. The median duration of mechanical ventilation was numerically shorter with dexmedetomidine than with propofol and significantly shorter than with midazolam. RCT: Effect of empirical treatment with moxifloxacin and meropenem vs. meropenem on sepsis-related organ dysfunction Reference: JAMA published early online on 13 June 2012 Source: JAMA Date published: 13/06/2012 17:04 Summary by: Hina Radia According to research published in the Journal of the American Medical Association, among adults with severe sepsis, treatment with combined meropenem and moxifloxacin compared with meropenem alone does not result in less organ failure. Early appropriate antimicrobial therapy leads to lower mortality rates associated with severe sepsis. The role of empirical combination therapy comprising at least 2 antibiotics of different mechanisms remains controversial, and this randomised controlled trial was conducted to compare the effect of moxifloxacin in combination with meropenem, with the effect of meropenem alone on sepsis-related organ dysfunction. The open-label parallel group trial involved 600 patients who fulfilled criteria for severe sepsis or septic shock who received monotherapy with moxifloxacin 400 mg every 24 hours (n=298) or combination therapy with meropenem 1g every 8 hours and moxifloxacin 400mg every 24 hours (n=302). The trial was performed at 44 intensive care units in Germany from October 16, 2007, to March 23, 2010. The number of evaluable patients was 273 in the monotherapy group and 278 in the combination therapy group. The intervention was recommended for 7 days and up to a maximum of 14 days after randomisation or until discharge from the intensive care unit or death, whichever occurred first. The primary outcome measure was degree of organ failure (mean of daily total Sequential Organ Failure Assessment [SOFA] scores over 14 days; score range: 0-24 points with higher scores indicating worse organ failure), Secondary outcome included 28-day and 90-day all-cause mortality. Survivors were followed up for 90 days. The following results were reported: • There was no statistically significant difference in mean SOFA scores between the meropenem and moxifloxacin group (8.3 points; 95% CI, 7.8-8.8 points) and the meropenem alone group (7.9 points; 7.5-8.4 points) (P = 0.36). • By day 28, there were 66 deaths (23.9%; 19.0%-29.4%) in the combination therapy group compared with 59 deaths (21.9%; 17.1%-27.4%) in the monotherapy group (P = 0.58). • By day 90, there were 96 deaths (35.3%; 29.6%-41.3%) in the combination therapy group compared with 84 deaths (32.1%; 26.5%-38.1%) in the monotherapy group (P = 0.43). • At least 1 adverse event occurred in 85 patients (28.1% 23.1%-33.5%]) in the combination therapy group and in 71 patients (24.2% [19.4%- 29.6%]) in the monotherapy group (P=0.31). The researchers conclude by highlighting several limitations of the study, although state that no beneficial effect of combination therapy including meropenem and moxifloxacin with regard to the 14- day mean SOFA score, or with regard to any secondary end point was observed. Presence and accuracy of drug dosage recommendations for continuous renal replacement therapy in tertiary drug information references Original article by: SK Gorman, RS Slavik, S Lam Reference: Canadian Journal of Hospital Pharmacy Jun 2012;65(3): Source: Canadian Journal of Hospital Pharmacy Keywords: Accuracy; Databases; Dose Calculation; Drug Administration Schedule; Haemodialysis; Kidney Function-Impaired; Reference Books; Date published: 25/06/2012 11:17 Summary by: Pharm-line Background: Clinicians commonly rely on tertiary drug information references to guide drug dosages for patients who are receiving continuous renal replacement therapy (CRRT). It is unknown whether the dosage recommendations in these frequently used references reflect the most current evidence. Objective: To determine the presence and accuracy of drug dosage recommendations for patients undergoing CRRT in 4 drug information references. Methods: Medications commonly prescribed during CRRT were identified from an institutional medication inventory database, and evidence-based dosage recommendations for this setting were developed from the primary and secondary literature. The American Hospital Formulary System-Drug Information (AHFS–DI), Micromedex 2.0 (specifically the DRUGDEX and Martindale databases) and the 5th edition of Drug Prescribing in Renal Failure (DPRF5) were assessed for the presence of drug dosage recommendations in the CRRT setting. The dosage recommendations in these tertiary references were compared with the recommendations derived from the primary and secondary literature to determine concordance. Results: Evidence-based drug dosage recommendations were developed for 33 medications administered in patients undergoing CRRT. The AHFS-DI provided no dosage recommendations specific to CRRT, whereas the DPRF5 provided recommendations for 27 (82%) of the medications and the Micromedex 2.0 application for 20 (61%) (13 (39%) in the DRUGDEX database and 16 (48%) in the Martindale database, with 9 medications covered by both). The dosage recommendations were in concordance with evidencebased recommendations for 12 (92%) of the 13 medications in the DRUGDEX database, 26 (96%) of the 27 in the DPRF5 and all 16 (100%) of those in the Martindale database. Conclusions: One prominent tertiary drug information resource provided no drug dosage recommendations for patients undergoing CRRT. However, 2 of the databases in an Internet-based medical information application and the latest edition of a renal specialty drug information resource provided recommendations for a majority of the medications investigated. Most dosage recommendations were similar to those derived from the primary and secondary literature. The most recent edition of the DPRF is the preferred source of information when prescribing dosage regimens for patients receiving CRRT. Hydroxyethyl starch 130/0.4 vs. Ringer's acetate in severe sepsis: RCT Reference: N Engl J Med published online 27 June 2012 Source: New England Journal of Medicine Date published: 28/06/2012 18:43 Summary by: Yuet Wan Hydroxyethyl starch (HES) 130/0.4 is widely used for fluid resuscitation in intensive care units (ICUs), but its safety and efficacy have not been established in patients with severe sepsis. The 6S Trial Group and the Scandinavian Critical Care Trials Group conducted a multicentre, parallel-group, blinded trial to compare fluid resuscitation in the ICU with 6% HES 130/0.4 or Ringer’s acetate (up to 33 ml/kg/day) in 804 such patients. The primary outcome measure was either death or end-stage kidney failure (dependence on dialysis) at 90 days after randomisation. At 90 days after randomisation, 798 were included in the modified intention-to-treat population, and the following findings reported: • 201 of 398 patients (51%) assigned to HES 130/0.4 had died, vs. 172 of 400 patients (43%) receiving Ringer’s acetate (relative risk, 1.17; 95% CI, 1.01 to 1.36; p = 0.03); 1 patient in each group had end-stage kidney failure. • 87 patients (22%) assigned to HES 130/0.4 were treated with renal-replacement therapy vs. 65 patients (16%) assigned to Ringer’s acetate (1.35, 1.01 to 1.80; p = 0.04) • 38 patients (10%) and 25 patients (6%) on HES and Ringer’s acetate, respectively, had severe bleeding (1.52; 0.94 to 2.48; p = 0.09). • The results were supported by multivariate analyses, with adjustment for known risk factors for death or acute kidney injury at baseline. The researchers conclude from these findings that “patients with severe sepsis assigned to fluid resuscitation with HES 130/0.4 had an increased risk of death at day 90 and were more likely to require renal-replacement therapy, as compared with those receiving Ringer’s acetate.” List of Contributors Contributor Nicola Rudall Newcastle Upon Tyne Hospitals NHS Foundation Trust, Nicola.Rudall@nuth.nhs.uk Andrew Turton Princes Royal University hospital andrew.turton@nhs.net Jennifer Murphy Wishaw General Hospital, Lanarkshire jennifer.murphy@lanarkshire.scot.nhs. uk Caroline Hamilton Derby Hospitals NHSF Trust c.hamilton18@tiscali.co.uk Olivia Moswela Radcliffe Infirmary olivia.moswela@orh.nhs.uk Patricia Ging MMUH patriciaging@eircom.net Journal Critical Medicine Intensive Medicine Care Care American Journal of Respiratory and Critical Care (First Fortnight) American Journal of Respiratory and Critical Care (Second Fortnight) and Neurosciences journals New England Journal of Medicine Mark Borthwick Oxford Radcliffe Hospitals mark.borthwick@orh.nhs.uk Circulation Internet Resources Emma Graham-Clarke Sandwell and West Birmingham Hospitals NHS Trust Birmingham emma.graham-clarke@swbh.nhs.uk Jane Hylands Wrightington, Wigan and Leigh NHS Trust jhylands@fsmail.net Lancet (Weekly) (+ Key articles from clinical nutrition and e-SPEN) JAMA (weekly) Contributor Annie Egan Nelson Hospital, NZ annie_egan2000@hotmail.com Journal Critical Care David Sapsford West Suffolk Hospital NHS Trust david.sapsford@wsh.nhs.uk British Journal Anaesthesia Clare Crowley Oxford Radcliffe Hospitals clare.crowley@orh.nhs.uk Hospital Pharmacy Quality and Safety in Healthcare John Dade St. James's University Hospital john.dade@leedsth.nhs.uk Thorax Andreas Fischer Royal Brompton & Harefield.
