RESUMO
BACKGROUND: Postoperative atrial fibrillation (POAF) is the most common complication occurring after cardiac surgery. Guidelines for the management of this complication are scarce, often resulting in differences in treatment strategy use among patients. OBJECTIVE: To evaluate the management of POAF in a cardiac surgery department, characterize the extent of its variability, and develop a standardized protocol. METHODS: This was an observational retrospective study with data from patients who underwent cardiac surgeries with subsequent POAF between January 1, 2017, and June 1, 2018. We assessed the difference in the proportions of patients whose first POAF episodes were treated with a rate control (RaC) strategy, a rhythm control (RhC) strategy, and both among different hospital units. We also assessed the mean duration of POAF episodes, POAF recurrences, and the management of anticoagulation. RESULTS: Data from 97 patients were included in this study. The POAF management strategy differed significantly among the 3 types of hospital units (P = 0.001). Considering all POAF episodes (including all recurrences), 83 of the 97 patients (85.6%) received amiodarone as part of the RhC strategy. Anticoagulation was used in 58 (59.8%) patients and was suboptimal according to the study criteria in 29.5% of the patients included. Based on these results, a hospital working group developed a standardized protocol for POAF management. CONCLUSIONS AND RELEVANCE: POAF management was heterogeneous at our institution. This article highlights the need for clear practice guidelines based on large prospective studies to provide care according to best practices.

BACKGROUND: Secondary prevention strategies after acute coronary syndrome (ACS) presentation with the use of drug combinations are essential to reduce the recurrence of cardiovascular events. However, lack of drug adherence is known to be common in this population and to be related to treatment failure. To improve drug adherence, we developed the "Mon Coeur, Mon BASIC" video. This online video has been specifically designed to inform patients about their disease and their current medications. Interactivity has been used to increase patient attention, and the video can also be viewed on smartphones and tablets. OBJECTIVE: The objective of this study was to assess the long-term impact of an informative web-based video on drug adherence in patients admitted for an ACS. METHODS: This randomized study was conducted with consecutive patients admitted to University Hospital of Lausanne for ACS. We randomized patients to an intervention group, which had access to the web-based video and a short interview with the pharmacist, and a control group receiving usual care. The primary outcome was the difference in drug adherence, assessed with the Adherence to Refills and Medication Scale (ARMS; 9 multiple-choice questions, scores ranging from 12 for perfect adherence to 48 for lack of adherence), between groups at 1, 3, and 6 months. We assessed the difference in ARMS score between both groups with the Wilcoxon rank sum test. Secondary outcomes were differences in knowledge, readmissions, and emergency room visits between groups and patients' satisfaction with the video. RESULTS: Sixty patients were included at baseline. The median age of the participants was 59 years (IQR 49-69), and 85% (51/60) were male. At 1 month, 51 patients participated in the follow-up, 50 patients participated at 3 months, and 47 patients participated at 6 months. The mean ARMS scores at 1 and 6 months did not differ between the intervention and control groups (13.24 vs 13.15, 13.52 vs 13.68, respectively). At 3 months, this score was significantly lower in the intervention group than in the control group (12.54 vs 13.75; P=.03). We observed significant increases in knowledge from baseline to 1 and 3 months, but not to 6 months, in the intervention group. Readmissions and emergency room visits have been very rare, and the proportion was not different among groups. Patients in the intervention group were highly satisfied with the video. CONCLUSIONS: Despite a lower sample size than we expected to reach, we observed that the "Mon Coeur, Mon BASIC" web-based interactive video improved patients' knowledge and seemed to have an impact on drug adherence. These results are encouraging, and the video will be offered to all patients admitted to our hospital with ACS.

The objective of this study was to investigate the population pharmacokinetics (PK) of amoxicillin in ICU burn patients and the optimal dosage regimens. This was a prospective study involving 21 consecutive burn patients receiving amoxicillin. PK data were analyzed using nonlinear mixed-effects modeling. Monte-Carlo simulations assessed the influence of various amoxicillin dosage regimens with identified covariates on the probability to achieve a target (PTA) value of time during which free amoxicillin concentrations in plasma exceeded the MIC (fT>MIC). A two-compartment model best described the data. Creatinine clearance (CLCR) and body weight (BW) influenced amoxicillin CL and central volume of distribution (V1), respectively. The median CLCR (Cockcroft-Gault formula) was high (128 ml/min), with 25% of patients having CLCRs of >150 ml/min. The CL, V1, and half-life (t1/2) values at steady state for a patient with a CLCR of 110 ml/min and BW of 70 kg were 13.6 liters/h, 9.7 liters, and 0.8 h, respectively. Simulations showed that a target fT>MIC of ≥50% was achieved (PTA > 90%) with standard amoxicillin dosage regimens (1 to 2 g every 6 to 8 h [q6-8h]) when the MIC was low (<1 mg/liter). However, increased dosages of up to 2 g/4 h were necessary in patients with augmented CLRs or higher MICs. Prolonging amoxicillin infusion from 30 min to 2 h had a favorable effect on target attainment. In conclusion, this population analysis shows an increased amoxicillin CL and substantial CL PK variability in burn patients compared to literature data with nonburn patients. Situations of augmented CLCR and/or high bacterial MIC target values may require dosage increases and longer infusion durations.

BACKGROUND: The state of digitalisation in the healthcare sector in Switzerland is lagging, even as the national electronic health record (EHR) is being gradually implemented. Little is known about the implementation of electronic prescribing systems, their auxiliary features or drug datasets in Swiss hospitals.The aim of this study was to understand which electronic systems are implemented to support doctors in Swiss hospitals during the medication prescribing process. METHODS: The survey was sent in spring 2021 to the chief pharmacists of the main Swiss hospitals. The survey focused on the introduction of the EHR, the clinical information system (CIS) and its prescribing module, as well as drug information data and clinical decision support systems (CDSS). RESULTS: The response rate was 98% (58/59 hospitals). Almost half of the hospitals (47%) were connected to the national EHR, almost all hospitals (86%) used a CIS and a vast majority of the hospitals (84%) had implemented electronic prescribing systems in their CIS. 10 years ago, around 63% of hospitals used a CIS and 40% were equipped with an electronic prescribing system. Today, CDSS of any kind were implemented in 50% of the hospitals, predominantly for drug-drug interactions. Drug master data were maintained in most hospitals (76%) via an automated interface, but mostly supplemented manually. Clinical drug information data were maintained in 74% of hospitals. In 67% of hospitals, datasets were imported via an automated interface. CONCLUSIONS: The digitalisation of the medical prescribing process in Swiss hospitals has progressed over the last decade. Drug prescriptions via electronic prescribing systems were introduced in most hospitals. However, this survey suggests that the current use of CDSS is far from exhausted, and that clinical drug information data could be maintained more efficiently. Optimising electronic support for healthcare professionals during the prescribing process still has considerable potential.

OBJECTIVES: Medication management is a core process in hospital administration. The safety, timeliness and efficiency of medication distribution may be improved by automating logistical and administrative aspects of the process. Forming an accurate high-level picture of current practices may help decision-makers to better advance the state of automation. This study aims to identify which systems for automating the medication process are currently in use in Swiss hospitals, and to what extent each system is used. METHODS: A 27-question survey was developed and distributed to Swiss Association of Public Health Administration and Hospital Pharmacists (GSASA) members. The survey focused on enterprise resource planning (ERP) systems, automation of in-hospital distribution and dispensing of pharmaceutical goods, bedside scanning, and the management of drug master data. RESULTS: The response rate was 98% (58/59 hospital pharmacies). All institutions had an ERP system in use, most frequently SAP (n=23, 39%). Electronic invoices from suppliers were fully processed by 37% and partially processed by 17% of respondents. Twenty-five percent of respondents reported performing bedside scanning for the purpose of medication administration. Automated medication distribution systems were available in 20 hospitals (34%), of which 13 were central robots and seven were decentralised systems. CONCLUSION: A considerable gap remains to achieve closed loop processes between multiple systems. The present results provide an inventory of existing systems and current trends for use by decision-makers in hospitals and hospital pharmacies.
RESUMO
BACKGROUND & AIMS: Major burns develop acute trace element (TE) deficiencies due to exudative losses of copper, selenium, and zinc from the wounds. A repletion strategy has been shown to decrease infectious and surgical complications. The TE doses have been adapted over time and the last adaptation, was not followed by the expected changes. The study aims at identifying the causes of the failure. METHODS: Retrospective cohort study including critically ill major burns patients admitted to intensive care with burns exceeding 20% of body surface area (BSA). Period A (2011-2015) included patients admitted before the dose change, and Period B patients after (2017-2020). Demographic variables, daily TE delivery, and weekly TE blood levels were extracted from the computerized information system (CIS). RESULTS: Altogether 71 patients completed the inclusion criteria (Periods A and B: 42 and 29 patients respectively). They were aged 38 (32) years and burned 35 (30) % BSA, with no severity differences. Comparing periods A and B, copper (p = 0.046) and selenium (p = 0.031) blood levels were significantly lower in B. The dose value extracted from CIS was as planned. Customization error was found: TE salts' weight had been entered instead of elemental weight in molar units. CONCLUSION: The lower TE repletion doses administered since 2017 resulted in a significant decrease in blood levels of Cu and Se. A CIS customisation error, confusing salt weight and elemental weight was the source of the error. A systematic quality control is crucial to identify systemic errors, as is the use of the standard international units.

BACKGROUND: The European Society of Cardiology recommends beta-blocker prescription after ST-segment elevation myocardial infarction (STEMI). Evidence for beta-blocker indication depends on the presence of left ventricular dysfunction (left ventricular ejection fraction [LVEF] <40%, class I level A; LVEF ≥40%, class IIa level B). In clinical practice, beta-blockers should be up-titrated to target doses as long as patients tolerate them. The aim of this study was to assess the patterns of beta-blocker prescription and up-titration after STEMI for one year after hospital discharge. METHODS: This observational study included patients admitted to a tertiary hospital for STEMI between April 2014 and April 2016. Patients with beta-blocker contraindications were excluded from the study. The primary outcomes were the patterns of beta-blocker prescription at discharge and at one year post-PCI, and the evolution of beta-blocker doses over the year. Beta-blocker doses were classified as low (<50% of the target dose) or high (≥50% target). As secondary outcomes, we assessed whether the beta-blocker prescriptions were different according to the type of hospital (university vs district) the patients were discharged from, and whether a short length of stay during the index event was related to a poor beta-blocker prescription at one year post-PCI. RESULTS: Overall, 266 patients were followed for one year. Of the 217 patients with LVEF ≥40%, 197 (90.8%) received beta-blocker prescriptions at hospital discharge. At the time of discharge, doses were high for 13 (6.0%) and low for 184 (84.8%) patients. In the latter group, nine (4.9%) doses were up-titrated to high during the year after STEMI. Of the 49 patients with LVEFs <40%, 46 (93.9%) received beta-blocker prescriptions at discharge. Doses were high for 3 (6.1%) and low for 43 (87.8%) patients. In the latter group, two (4.7%) doses were up-titrated to high during the year after STEMI. Patients transferred to district hospitals were more likely to have no beta-blocker prescription at discharge in both LVEF groups. Finally, patients without any beta-blocker prescription at one year were more likely to have had a short university hospital stay during the index event. CONCLUSION: Beta-blocker prescription after STEMI remains prevalent, but most doses are low and up-titration within one year is rare. This raises concern, particularly for patients with LVEFs <40%. Our findings highlight the changes in clinical practice over the last few decades, which corroborate with the latest evidence-based findings.

PURPOSE: Stress ulcer prophylaxis prescriptions might not be sufficiently challenged throughout a patient's stay in an intensive care unit (ICU) and might be erroneously maintained after ICU discharge. This study aimed to determine (1) stress ulcer prophylaxis adequacy in ICU and (2) the proportion of patients receiving inappropriate stress ulcer prophylaxis after ICU discharge. MATERIAL AND METHODS: This was an observational, single centre study (University Hospital Lausanne, Switzerland). All patients without a previous indication for acid-suppressive therapy and admitted to our ICU for >24 hrs during a two-month period were included. The adequacy of stress ulcer prophylaxis prescriptions according to our guidelines was assessed. We then assessed stress ulcer prophylaxis prescriptions and their adequacy on ICU and hospital discharge, as well as the costs associated with inadequate prescription. RESULTS: Of the 372 patients admitted during the study period, 140 (855 patient-days) fulfilled the inclusion criteria. Of these, 130 (92.9%) received stress ulcer prophylaxis in the ICU (796 [93.1%] patient-days). Stress ulcer prophylaxis consisted of esomeprazole in 686 (86.2%) patient-days. Overall, stress ulcer prophylaxis was inadequate in 558 (65.3%) patient-days, mostly because it was prescribed while not indicated (543 patient-days [63.5%]). On ICU discharge, stress ulcer prophylaxis prescription was inadequately maintained in 55 patients (51.9% of survivors). Similarly, stress ulcer prophylaxis was inadequately maintained on hospital discharge in 30 (28% of survivors) patients. We estimated the in-hospital cost of inadequate stress ulcer prophylaxis prescription as approximately CHF 2870 per year. Outpatient therapy maintenance would be associated with additional costs ranging from CHF 33,912 to 92,692 (EUR 31,832 to 87,012) for each additional year they receive the therapy, depending on the medication used. CONCLUSIONS: The adequacy of stress ulcer prophylaxis in the ICU is low. In addition, the prescription is frequently continued after ICU and many patients are even discharged home with inadequate acid-suppressive therapy.  .

AIM: American and European associations of cardiology published specific guidelines about recommended drugs for secondary prevention in ST-segment elevation myocardial infarction (STEMI) patients. Our aim was to assess whether drug prescription for STEMI patients was in accordance with the guidelines at discharge and after 1 year. METHOD: We used data of 361 patients admitted for STEMI in a tertiary hospital in Switzerland from 2014 to 2016. We assessed the adequacy of prescription of recommended drugs at two time points: discharge and after 1 year. Medications assessed were aspirin, P2Y12 inhibitors, statin, angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) and ß-blockers. We took into account several criteria like statin dosage (low versus high intensity) and presence of contraindication for consideration of optimal therapy. Predictors of incomplete prescription of guideline medications were then assessed with multivariate logistic regression models. RESULTS: From discharge (n = 358) to 1-year follow-up (n = 303), rate of optimal prescription was reduced from 98.6 to 91.7% for aspirin, from 93.9 to 79.1% for P2Y12 inhibitors, from 83.8 to 65.7% for statins, from 98.6 to 95.6% for ACEIs/ARBs, and from 97.1 to 96.9% for ß-blockers. Predictors of incomplete prescription of guideline medications at discharge were female sex (odds ratio [OR] 2.54, p = 0.007), active or former smoker status (OR 2.29, p = 0.017), multivessel disease (OR 2.07, p = 0.022), left ventricular ejection fraction < 40% (OR 2.49, p = 0.008), and transfer to cardiac surgery (OR 9.66, p = 0.018). At 1 year, age > 65 (OR 1.92, p = 0.036) remained the only significant predictor. CONCLUSION: The present study showed a high prescription rate of guideline-recommended medications in a referral center for primary percutaneous coronary intervention. At discharge, women and co-morbid patients were at the highest risk of incomplete prescription of guideline medications, whereas long-term prescription was suboptimal for elderly. A drug lacking at time of discharge was rarely introduced within the year, which underscores the paramount importance of optimal prescription at time of discharge. Strategies like implementing a standardized prescription could reduce the proportion of suboptimal prescription. It could therefore be one way to improve the long-term quality of care of our patients to the highest level. This study used local data from AMIS Plus-National Registry of Acute Myocardial Infarction in Switzerland (NCT01305785).

OBJECTIVES: To assess the feasibility and main obstacles to the implementation of a medication reconciliation (MR) process in a Swiss hospital and to develop a standardised method which can be used in similar healthcare systems. METHODS: For this prospective, observational single-centre and single-ward study, a best possible medication history (BPMH) was established by a clinical pharmacist for 147 patients with heart failure based on two sources and a patient interview for each case. Identified discrepancies with medication histories established during emergency service were conveyed to the ward physician. At the end of each hospital stay, the planned discharge treatments were compared with the BPMHs to identify discrepancies and to propose modifications. After a final validation, the comparative treatment plans were distributed. RESULTS: MR was conducted for 120 (82%) patients and the mean time needed was 74 min/patient. At least one discrepancy was identified among 94% of the patients on admission, with 4.1 discrepancies found per patient (mainly omissions). At discharge, 83% of the patients had at least one discrepancy, with 2.3 discrepancies found per patient (mainly unintentional substitutions). The majority (86%) of pharmaceutical interventions to adjust the discharge prescriptions were accepted by the physician. CONCLUSIONS: A standardised method of MR which offers precise definitions of discrepancies and key tools for the process was developed. This method was applicable to most of our cohort and it effectively identified medication discrepancies. Two potential obstacles for its implementation are the time needed for MR and the questionable impact of pharmaceutical interventions on discrepancies.
RESUMO
BACKGROUND & AIMS: Major burn patients are characterized by large exudative losses of Cu, Se and Zn. Trace element (TE) repletion has been shown to improve clinical outcome. Having increased the TE doses over time, the study aimed at analysing if our repletion protocol corrected TE plasma concentrations and if the necessity for continuous renal replacement therapy (CRRT) might increase the TE needs. METHODS: Retrospective analysis of prospectively collected data in burn patients requiring intensive care (ICU) between 1999 and 2015. INCLUSION CRITERIA: Admission on day 1, full treatment, burned surface area (TBSA) ≥20% and ≥1 TE plasma determination during the stay. Four groups were constituted according to protocol changes. Period 1 (P1): 1999-2000, P2: 2001-2005, P3: 2006-2010, P4: 2011-2015. Changes consisted in increasing TE repletion doses and duration. Demographic data, daily TE intakes and weekly plasma concentrations were retrieved for the first 21 ICU-days. Data as median (IQR). RESULTS: 139 patients completed the criteria, aged 37 (28) years, burned on 35 (25) % TBSA. As a result of prescription, Cu, Se and Zn intakes increased significantly between P1 and P4, resulting in normalization of plasma Cu (16 µmol/l) since P3 and Zn (13.5 µmol/l) since P2. Median plasma Se were above reference range (1400 nmol/l) during P3 and P4. CRRT patients required higher doses of Cu for maintenance within normal ranges. CONCLUSION: This dose finding study shows that the latest repletion protocol is safe and normalizes Cu and Zn concentrations. Se doses result in supra-normal Se concentrations, suggesting prescription reduction. CRRT patients are at high risk of Cu depletion and require specific monitoring.

AIMS: We evaluated the effectiveness of a multidisciplinary transition plan to reduce early readmission among heart failure patients. METHODS AND RESULTS: We conducted a before-and-after study in a tertiary internal medicine department, comparing 3 years of retrospective data (pre-intervention) and 13 months of prospective data (intervention period). Intervention was the introduction in 2013 of a transition plan performed by a multidisciplinary team. We included all consecutive patients hospitalized with symptomatic heart failure and discharged to home. The outcomes were the fraction of days spent in hospital because of readmission, based on the sum of all days spent in hospital, and the rate of readmission. The same measurements were used for those with potentially avoidable readmissions. Four hundred thirty-one patients were included and compared with 1441 patients in the pre-intervention period. Of the 431 patients, 138 received the transition plan while 293 were non-completers. Neither the fraction of days spent for readmissions nor the rate of readmission decreased during the intervention period. However, non-completers had a higher rate of the fraction of days spent for 30 day readmission (19.2% vs. 16.1%, P = 0.002) and for potentially avoidable readmission (9.8% vs. 13.2%, P = 0.001). The rate of potentially avoidable readmission decreased from 11.3% (before) to 9.9% (non-completers) and 8.7% (completers), reaching the adjusted expected range given by SQLape® (7.7-9.1%). CONCLUSIONS: A transition plan, requiring many resources, could decrease potentially avoidable readmission but shows no benefit on overall readmission. Future research should focus on potentially avoidable readmissions and other indicators such as patient satisfaction, adverse drug events, or adherence.

OBJECTIVE: Several trace elements are essential for immunity and wound healing, particularly after major burns. Continuous renal replacement therapy (CRRT), which is used to treat renal failure, causes significant trace elements losses. The aim of the present review is to update the current literature and draw attention to this type of complication, as copper deficiency is rarely suspected and diagnosed in clinical conditions and may occur in chronic critically ill patients. METHODS: This is an emblematic case report and review of literature. RESULTS: Major copper and selenium deficiencies were documented in a patient with major burns complicated by renal failure. The main cause was effluent loss during prolonged CRRT. The copper deficit resulted in life-threatening bradycardia and the alteration of lipid metabolism with severe hypertriglyceridemia. The published data are scarce, but trace element losses with effluent have been previously documented, as has the affect of copper deficiency on cardiac rhythm. CONCLUSION: The literature regarding the specific requirements for chronically critically ill patients is limited. During prolonged CRRT, copper and selenium levels decrease and probably should be monitored during prolonged therapy. Research in this area is required.

Background Prescribing for the elderly is challenging. A previous observational study conducted in our geriatric psychiatry admission unit (GPAU) using STOPP/START criteria showed a high number of potentially inappropriate drug prescriptions (PIDPs). A clinical pharmacist was added to our GPAU as a strategy to reduce PIDPs. Objective The objective of the present study was to assess the impact of a clinical pharmacist on PIDPs by measuring acceptance rates of pharmacist interventions (PhIs). Setting This study was conducted at the GPAU of Lausanne University Hospital. Method The clinical pharmacist attended four GPAU meetings weekly. Complete medication reviews were performed daily. The clinical pharmacist conducted standard analyses based on clinical judgment and STOPP/START criteria assessment. A PhI was generated when a PIDP was detected. When a PhI was accepted, the PIDP was considered as eliminated. Acceptance rate of PhI was calculated (number of PhI accepted/total number of PhI). Main outcome measure PhIs acceptance rates. Results In a cohort of 102 patients seen between July 2013 and February 2014, a total of 697 PhIs (average 6.8/patient) were made based on standard evaluation (n = 479) and STOPP/START criteria (n = 243). The global acceptance rate was 68% (standard, 78%; STOPP/START, 47%). Conclusion Good PhIs acceptance rates demonstrated that a clinical pharmacist can reduce PIDPs in a GPAU. PhIs based on standard evaluation had a higher acceptance than those based on STOPP/START criteria, probably because they are better adapted to individual patients. However, these two evaluation approaches can be used in a complementary manner.

PURPOSE: The control of antibiotic resistance and nosocomial infections are major challenges for specialized burn centres. Early detection of those epidemic outbreaks is crucial to limit the human and financial burden. We hypothesize that data collected by antibiotic consumption medico-economic surveys could be used as warning signal to detect early nosocomial outbreaks. METHODS: A retrospective analysis was conducted that included all burn patients staying >48h on the Lausanne BICU (Burn Intensive Care Unit) between January 2001 and October 2012 who received systemic therapeutic antibiotics. Infection episodes were characterized according to predefined criteria. Antibiotic consumption data, obtained from the quarterly surveillance of drug consumption surveys, were translated into defined daily doses (DDDs). RESULTS: In total, 297 out of 414 burn patients stayed >48h, giving a total of 7458 'burn-days'. We identified 610 infection episodes (burn wound [32.0%], respiratory [31.1%], and catheter [21.8%]), from 774 microorganisms. Pseudomonas aeruginosa (26.2%), Staphylococcus aureus (11.5%), and Candida albicans (7.0%) were the main pathogens. We observed three distinct outbreaks of P. aeruginosa infections in 2002-2003, 2006, and 2009-2011. These outbreaks correlated with an increase in the DDDs of anti-Pseudomonas antibiotics. CONCLUSIONS: Our data support a paradigm shift in the epidemiological surveillance of nosocomial P. aeruginosa epidemics in burn centres, using the rise in antibiotic consumption as an early trigger to initiate the molecular typing of P. aeruginosa strains and the reinforcement of standard infection control procedures.

Antibiotics are widely used in critical care and adequate empirical treatments has a significant impact on the outcome of many patients. Most nosocomial infections may be due to multidrug-resistant pathogens and requires empirical borad spectrum coverage before identification of the etiologic agents. This is associated with overuse of antibiotics which contributes to the further increase in multidrug-resistances. In this context, new strategies targeted at antibiotic control, such as guidelines and de-escalation are needed to control this evolution.

BACKGROUND & AIMS: Trace elements (TE) are involved in the immune and antioxidant defences which are of particular importance during critical illness. Determining plasma TE levels is costly. The present quality control study aimed at assessing the economic impact of a computer reminded blood sampling versus a risk guided on-demand monitoring of plasma concentrations of selenium, copper, and zinc. METHODS: Retrospective analysis of 2 cohorts of patients admitted during 6 months periods in 2006 and 2009 to the ICU of a University hospital. INCLUSION CRITERIA: to receive intravenous micronutrient supplements and/or to have a TE sampling during ICU stay. The TE samplings were triggered by computerized reminder in 2006 versus guided by nutritionists in 2009. RESULTS: During the 2 periods 636 patients met the inclusion criteria out of 2406 consecutive admissions, representing 29.7% and 24.9% respectively of the periods' admissions. The 2009 patients had higher SAPS2 scores (p = 0.02) and lower BMI compared to 2006 (p = 0.007). The number of laboratory determinations was drastically reduced in 2009, particularly during the first week, despite the higher severity of the cohort, resulting in à 55% cost reduction. CONCLUSIONS: The monitoring of TE concentrations guided by a nutritionist resulted in a reduction of the sampling frequency, and targeting on the sickest high risk patients, requiring a nutritional prescription adaptation. This control leads to cost reduction compared to an automated sampling prescription.

PURPOSE: Adequate empirical antibiotic dose selection for critically ill burn patients is difficult due to extreme variability in drug pharmacokinetics. Therapeutic drug monitoring (TDM) may aid antibiotic prescription and implementation of initial empirical antimicrobial dosage recommendations. This study evaluated how gradual TDM introduction altered empirical dosages of meropenem and imipenem/cilastatin in our burn ICU. METHODS: Imipenem/cilastatin and meropenem use and daily empirical dosage at a five-bed burn ICU were analyzed retrospectively. Data for all burn admissions between 2001 and 2011 were extracted from the hospital's computerized information system. For each patient receiving a carbapenem, episodes of infection were reviewed and scored according to predefined criteria. Carbapenem trough serum levels were characterized. Prior to May 2007, TDM was available only by special request. Real-time carbapenem TDM was introduced in June 2007; it was initially available weekly and has been available 4 days a week since 2010. RESULTS: Of 365 patients, 229 (63%) received antibiotics (109 received carbapenems). Of 23 TDM determinations for imipenem/cilastatin, none exceeded the predefined upper limit and 11 (47.8%) were insufficient; the number of TDM requests was correlated with daily dose (r=0.7). Similar numbers of inappropriate meropenem trough levels (30.4%) were below and above the upper limit. Real-time TDM introduction increased the empirical dose of imipenem/cilastatin, but not meropenem. CONCLUSIONS: Real-time carbapenem TDM availability significantly altered the empirical daily dosage of imipenem/cilastatin at our burn ICU. Further studies are needed to evaluate the individual impact of TDM-based antibiotic adjustment on infection outcomes in these patients.

The authors describe an invasive Aspergillus fumigatus deep-burn wound infection in a severely burned patient that was successfully treated with a combination of topical terbinafine and systemic voriconazole antifungal therapy. To our knowledge, this is the first case report describing the effective control of an invasive deep-burn wound infection using this combination.

OBJECTIVE: To test the dose response effect of infused fish oil (FO) rich in n-3 PUFAs on the inflammatory response to endotoxin (LPS) and on membrane incorporation of fatty acids in healthy subjects. DESIGN: Prospective, sequential investigation comparing three different FO doses. SUBJECTS: Three groups of male subjects aged 26.8 +/- 3.2 years (BMI 22.5 +/- 2.1). INTERVENTION: One of three FO doses (Omegaven10%) as a slow infusion before LPS: 0.5 g/kg 1 day before LPS, 0.2 g/kg 1 day before, or 0.2 g/kg 2 h before. MEASUREMENTS AND RESULTS: Temperature, hemodynamic variables, indirect calorimetry and blood samples (TNF-alpha, stress hormones) were collected. After LPS temperature, ACTH and TNF-alpha concentrations increased in the three groups: the responses were significantly blunted (p < 0.0001) compared with the control group of the Pluess et al. trial. Cortisol was unchanged. Lowest plasma ACTH, TNF-alpha and temperature AUC values were observed after a single 0.2 g/kg dose of FO. EPA incorporation into platelet membranes was dose-dependent. CONCLUSIONS: Having previously shown that the response to LPS was reproducible, this study shows that three FO doses blunted it to various degrees. The 0.2 g/kg perfusion immediately before LPS was the most efficient in blunting the responses, suggesting LPS capture in addition to the systemic and membrane effects.
