ABSTRACT
Videolaryngoscopy is a suitable alternative to flexible bronchoscopy to facilitate awake tracheal intubation. The relative effectiveness of these techniques in clinical practice is unknown. We compared flexible nasal bronchoscopy with Airtraq® videolaryngoscopy in patients with an anticipated difficult airway scheduled for awake tracheal intubation. Patients were allocated randomly to flexible nasal bronchoscopy or videolaryngoscopy. All procedures were performed with upper airway regional anaesthesia blockade and a target-controlled intravenous infusion of remifentanil. The success rate with the allocated technique was the primary outcome. A non-inferiority analysis with a predefined limit of 8% was planned. Seventy-eight patients were recruited, allocated randomly and analysed. The rate of successful intubation was 97% and 82% in the flexible bronchoscopy and videolaryngoscopy groups, respectively, p = 0.032. The median (IQR [range]) time to tracheal intubation was shorter with the Airtraq, 163 (105-332 [40-1004]) vs. 217 (180-364 [120-780]) s, p = 0.030. There were no significant differences for complications found between the groups. The median visual analogue scale for ease of intubation was 8 (7-9 [0-10]) for Airtraq vs. 8 (7-9 [0-10]) for flexible bronchoscopy, p = 0.710. The median visual analogue scale for patient comfort for Airtraq was 8 (6-9 [2-10]) vs. 8 (7-9 [3-10]) for flexible bronchoscopy, p = 0.370. The Airtraq videolaryngoscope is not non-inferior to flexible bronchoscopy for awake tracheal intubation in a clinical setting when awake tracheal intubation is indicted. It may be a suitable alternative when judged on a case-by-case basis.

BACKGROUND: Retrospective studies in hematological unit have suggested that single red blood cell (1-RBC) unit transfusion policy may reduce the number of RBC used without negative clinical impact. METHOD: Acute leukemia patients requiring intensive chemotherapy or patients receiving autologous or allogeneic transplantation were randomly assigned to receive either single RBC (1-RBC arm) or double RBC (2-RBC arm) per transfusion with a hemoglobin trigger of 8 g/dL. The primary composite endpoint was the percentage of patients experiencing serious complications, such as a non-hematological adverse event grade ≥ 3 or intensive care admission or death. FINDINGS: A total of 981 and 592 RBC transfusions were required in the 1-RBC arm (n = 125) and the 2-RBC arm (n = 120), respectively. The mean pre-transfusion hemoglobin levels were 7.49 ± 0.83 g/dL in the 1-RBC arm and 7.46 ± 0.67 g/dL in the 2-RBC arm (p = 0.275). The predefined non-inferiority criteria was achieved with 28/125 patients reaching the primary endpoint in the 1-RBC arm (22.4 %) and 28/120 patients in the 2-RBC arm (23.3 %) (Risk difference 0.009; 95 %, Confidence interval [-0.0791 to 0.0978], p = 0.021). The median (IQR) of RBC units transfused per patient was 7 (4-12) in the 1-RBC arm and 8 (4-12) in 2-RBC arm. Hemoglobin levels at discharge were also comparable in both arms. INTERPRETATION: The results of this trial indicate that a single RBC transfusion policy is not inferior to a double RBC transfusion policy for patients receiving a bone marrow transplant or intensive chemotherapy in a hematological intensive care unit. However, the single RBC transfusion policy did not reduce the number of RBC units transfused per stay. FUNDING: This trial was funded by a grant from the French Ministry of Health.

General or regional anaesthesia can be used for chronic subdural haematoma evacuation, but no study has compared these types of anaesthesia in terms of peri-operative outcomes. This single-centre, prospective, randomised study included adult patients (age ≥ 18 years) undergoing surgical chronic subdural haematoma evacuation. Patients were randomly allocated to general (target-controlled total intravenous anaesthesia with propofol and remifentanil) or regional anaesthesia (bilateral scalp block with remifentanil sedation if required). The primary outcome measure was duration of hospital stay, based on the day patients were judged by an investigator blinded from the allocation group to be medically fit for discharge. Secondary outcomes included: rate of regional anaesthesia failure; rate of intra-operative and postoperative adverse events at 24 hours; and pain scores at 24 hours. Data from 60 patients were analysed (30 general anaesthesia and 30 regional anaesthesia). Median (IQR [range]) time until patients were judged medically fit for discharge was 3 (3-3 [2-10]) days and 3 (2-5 [2-15]) days for general and regional anaesthesia, respectively (p = 0.700). Regional anaesthesia failed in two patients. There were more intra-operative adverse events in patients who received general anaesthesia (25 vs. 11, respectively; p = 0.001). The occurrence of postoperative adverse events was similar for general and regional anaesthesia (16 vs. 13 patients, respectively; p = 0.605). In patients requiring chronic subdural haematoma evacuation, general and regional anaesthesia are comparable in terms of duration of time until medically fit for discharge and occurrence of postoperative complications. The rate of intra-operative adverse events (mainly arterial hypotension) is greater with general anaesthesia.

OBJECTIVES: The prevention of catheter-related bloodstream infection (CRBSI) has been an area of intense research, but the heterogeneity of endpoints used to define catheter infection makes the interpretation of randomized controlled trials (RCTs) problematic. The aim of this study was to determine the validity of different endpoints for central venous catheter infections. DATA SOURCES: (a) Individual-catheter data were collected from 9428 catheters from four large RCTs; (b) study-level data from 70 RCTs were identified with a systematic search. Eligible studies were RCTs published between January 1987 and October 2018 investigating various interventions to reduce infections from short-term central venous catheters or short-term dialysis catheters. For each RCT the prevalence rates of CRBSI, quantitative catheter tip colonization, catheter-associated infection (CAI) and central line-associated bloodstream infection (CLABSI) were extracted for each randomized study arm. METHODS: CRBSI was used as the gold-standard endpoint, for which colonization, CAI and CLABSI were evaluated as surrogate endpoints. Surrogate validity was assessed as (1) the individual partial coefficient of determination (individual-pR2) using individual catheter data; (2) the coefficient of determination (study-R2) from mixed-effect models regressing the therapeutic effect size of the surrogates on the effect size of CRBSI, using study-level data. RESULTS: Colonization showed poor agreement with CRBSI at the individual-patient level (pR2 = 0.33 95% CI 0.28-0.38) and poor capture at the study level (R2 = 0.42, 95% CI 0.21-0.58). CAI showed good agreement with CRBSI at the individual-patient level (pR2 = 0.80, 95% CI 0.76-0.83) and moderate capture at the study level (R2 = 0.71, 95% CI 0.51-0.85). CLABSI showed poor agreement with CRBSI at the individual patient level (pR2 = 0.34, 95% CI 0.23-0.46) and poor capture at the study level (R2 = 0.28, 95% CI 0.07-0.76). CONCLUSIONS: CAI is a moderate to good surrogate endpoint for CRBSI. Colonization and CLABSI do not reliably reflect treatment effects on CRBSI and are consequently more suitable for surveillance than for clinical effectiveness research.

OBJECTIVES: To assess the prevalence and the management of the lower urinary tract dysfunction (LUTD) in institutionalized handicapped adults. MATERIALS AND METHODS: Descriptive transversal observational study. Epidemiological study. RESULTS: In this study realized in 150 residents of 6 nursing homes for adult, the prevalence of LUTD in institutionalized handicapped adults was 88.67% (133/150). This prevalence was 91.36% (74/81) for women versus 85.51% (59/69) for men, (P=0.260); 93.33% (14/15) in medical housing units [foyer d'accueil médicalisé (FAM)] versus 88.15% (119/135) in specialized housing units [maison d'accueil spécialisé (MAS)], (P=1); 80% (52/65) for those who walked without technical support, 89.47% (17/19) for those who walked with technical support, 98.08% (51/52) for the wheelchair users who were not able to walk, and 92.86% (13/14) for those who were not able to walk or to use wheelchair, (P=0.004); 69.81% (37/53) for those who were able to signal the need to void versus 98.97% (96/97) for those who were not able, (P=0.0000003); 76.92% (50/60) for those who were able to realize the transfers independently, versus 97.65% (83/85) for those who were not able, (P=0.0002); 67.39% (31/46) for those who could dress and undress by themselves versus 98.08% (102/104) for those who could not, (P=0.0000002); 77.27% (17/22) for water intake>2L, 91.67% (55/60) between 1.5 and 2L, 87.5% (49/56) between 1 and 1.5L, and 100% (12/12) for water intake<1L, (P=0.170). The LUTD were more frequent in people with physical disability (OR=10.70[1.53-75.09], P=0.017), in those with mental disability (OR=5.85[1.39-24.67], P=0.016), and in those with urological comorbidity (OR=9.70[1.25-75.55], P=0.03). For the management of the LUTD, the prevalence of expert medical advice was 9.77%, 24.81% (33/133) for the further examination, 16.54% (22/133) for rehabilitation treatment, 6.77% (9/133) for drug treatment, 2.26% (3/133) for surgical treatment, and 82.71% (110/133) for medical device. CONCLUSION: In this study, the prevalence of LUTD in institutionalized handicapped adults was 88.67%. LEVEL OF EVIDENCE: 4.

INTRODUCTION: Aneurysmal subarachnoid hemorrhage (SAH) is a devastating form of stroke, which often causes acute hydrocephalus requiring the insertion of an external ventricular drain (EVD). A major complication of aneurysmal SAH is delayed cerebral ischemia (DCI). As DCI is linked to the presence of blood within the subarachnoid space, it has been hypothesized that removing this blood may decrease the risk of DCI. This could be achieved by injecting a fibrinolytic agent through the EVD, a strategy called intraventricular fibrinolysis (IVF). Here, we propose to conduct a phase III trial to directly evaluate the impact of IVF after aneurysmal SAH. MATERIALS AND METHODS: We will perform an open-label randomized controlled trial comparing the standard of care, i.e. EVD alone, to the experimental treatment, i.e. IVF. We plan to include 440 patients to be able to show a 10% increase in the rate of good functional outcomes in the EVD+IVF group compared to the EVD alone group (α=0.05 and ß=0.8). To obtain such sample, a multicenter trial is required, and to date 17 research sites in France have agreed to participate. PERSPECTIVE: FIVHeMA would be the first phase III trial evaluating the relevance of IVF in aneurysmal SAH. If IVF is shown to be beneficial, then a new therapeutic tool will be available to improve the outcomes of aneurysmal SAH patients.

BACKGROUND AND PURPOSE: 3D-TOF-MRA and DSA are 2 available tools to demonstrate neurovascular involvement in primary central nervous system vasculitis. We aimed to compare the diagnostic concordance of vessel imaging using 3D-TOF-MRA and DSA in patients with primary central nervous system vasculitis. MATERIALS AND METHODS: We retrospectively identified all patients included in the French primary central nervous system vasculitis cohort of 85 patients who underwent, at baseline, both intracranial 3D-TOF-MRA and DSA in an interval of no more than 2 weeks and before treatment initiation. Two neuroradiologists independently reviewed all 3D-TOF-MRA and DSA imaging. Brain vasculature was divided into 25 arterial segments. Concordance between 3D-TOF-MRA and DSA for the identification of arterial stenosis was assessed by the Cohen κ Index. RESULTS: Thirty-one patients met the inclusion criteria, including 20 imaged with a 1.5T MR unit and 11 with a 3T MR unit. Among the 25 patients (81%) with abnormal DSA findings, 24 demonstrated abnormal 3D-TOF-MRA findings, whereas all 6 remaining patients with normal DSA findings had normal 3D-TOF-MRA findings. In the per-segment analysis, concordance between 1.5T 3D-TOF-MRA and DSA was 0.82 (95% CI, 0.75-0.93), and between 3T 3D-TOF-MRA and DSA, it was 0.87 (95% CI, 0.78-0.91). CONCLUSIONS: 3D-TOF-MRA shows a high concordance with DSA in diagnostic performance when analyzing brain vasculature in patients with primary central nervous system vasculitis. In patients with negative 3T 3D-TOF-MRA findings, the added diagnostic value of DSA is limited.

BACKGROUND: The aim of the study was to analyse efficacy, safety, and health-related quality of life (HRQoL) for sorafenib treatment in patients with metastatic uveal melanoma. METHODS: A multicentre, single-arm phase II trial was conducted. The primary objective was to determine the non-progression rate (RECIST) at 24 weeks for patients receiving sorafenib at a dose of 800 mg per day. Secondary endpoints included progression-free survival (PFS), overall survival (OS), toxicity, and HRQoL. RESULTS: Thirty-two patients were included. Ten patients showed non-progression at 24 weeks (31.2%) without objective tumour responses. The estimated 24-week PFS was 31.2% (95% CI: 14.8%-47.6%) and the estimated 24-week OS was 62.5% (95% CI: 45.4%-79.6%). Ten patients (34.3%) had at least one grade 3 or 4 adverse reaction and 12 patients (41.4%) required dose modifications due to toxicity. At 24 weeks, no patient had an improvement in global HRQoL and 87.5% experienced a permanent increase in physical fatigue. CONCLUSIONS: Sorafenib demonstrated non-progression at 24 weeks in 31.2% of patients. However, 41.4% of patients required dose modifications due to toxicity and no improvement in HRQoL was demonstrated.

INTRODUCTION: Controversy exists regarding the treatment of infants with symptomatic nasolacrimal duct obstruction. One philosophy advocates "early" nasolacrimal duct probing, generally in the office - a relatively common approach in France, while others prefer to wait until the age of 12 months to offer a procedure under general anesthesia. The goal of this study is to report results of immediate office probing for congenital nasolacrimal duct obstruction (CNLDO) under age 1 year in terms of efficacy and cost. METHODS: A retrospective study was performed on 329 patients (443 eyes) treated by probing for CNLDO under the age of 12 months age. A single probing was performed at the first visit in the office under topical anesthesia without sedation. In order to determine the factors associated with failure of probing, univariate analysis was performed using the Student t-test, Pearson's, homogeneity Chi(2) or Fisher's exact tests. For cost evaluation, hypothetical estimates of spontaneous resolution month by month were used according to data in the literature, along with health insurance reimbursement data. RESULTS: The ages of the patients ranged from 2 to 11 months (mean 7.0 ± SD 2.3). The overall success rate for cure by immediate office probing was 76.7%. Unilateral CNLDO had an 80.4% success rate whereas bilateral CNLDO had a 73.2% success rate for each eye (P=0.09). Discharge during probing was associated with failed probing (P=0.02). The cost for the spontaneous resolution strategy was 1.56 times higher than for the immediate probing strategy. A strategy which would apply the spontaneous resolution strategy for children ≤ 5 months and the probing strategy to children>5 months would be the most cost-effective. CONCLUSIONS: Immediate office probing between the ages of 5 to 12 months is a safe, effective method to relieve CNLDO and is the most cost-effective.

BACKGROUND: Endothelial dysfunction is common in patients with heart failure and is associated with poor clinical outcome. Cardiac rehabilitation is able to enhance peripheral endothelial function but its impact on coronary vasomotion remains unknown. We aimed to evaluate the effect of cardiac rehabilitation on coronary vasomotion in patients with heart failure. METHOD: We prospectively enrolled 29 clinically stable heart failure patients from non-ischaemic dilated cardiomyopathy and without coronary risk factors. Myocardial blood flow was quantified using (15)-O water positron emission tomography at rest and during a cold pressor test, before and after 12 weeks of cardiac rehabilitation and optimization of medical therapy. RESULTS: Rest myocardial blood flow was significantly improved after the completion of rehabilitation compared to baseline (1.31 ± 0.38 mL/min/g vs. 1.16 ± 0.41 mL/min/g, p = 0.04). The endothelium-related change in myocardial blood flow from rest to cold pressor test and the percentage of myocardial blood flow increase during the cold pressor test were both significantly improved after cardiac rehabilitation (respectively from -0.03 ± 0.22 mL/min/g to 0.19 ± 0.22 mL/min/g, p < 0.001 and from 101.5 ± 16.5% to 118.3 ± 24.4%, p < 0.001). Left ventricular ejection fraction, plasma levels of brain natriuretic peptide, maximal oxygen consumption and the Minnesota Living with Heart Failure Questionnaire score were also significantly improved. The improvement was not related to uptitration of medical therapy. CONCLUSIONS: Coronary endothelial function is altered in patients with heart failure due to non-ischaemic dilated cardiomyopathy. In these patients, cardiac rehabilitation significantly improves coronary vasomotion.

OBJECTIVES: Simplification of antiretroviral therapy enhances a patient's adherence but a new formulation could also lead to new adverse events and changes in daily routine. This study compared medication adherence, tolerance and satisfaction among subjects switching from a two-tablet tenofovir/emtricitabine/efavirenz regimen to a one-tablet regimen. METHODS: Clinical and sociodemographic data were collected and three surveys were administered at month 0 (=switch), and then 1 and 4-6 months after the switch: the Beliefs about Medicines Questionnaire, the HIV-symptom index questionnaire, the Short HIV Treatment Satisfaction Questionnaire, the Swiss HIV Cohort Study (SHCS) two-item adherence questionnaire, and a questionnaire on daily combination antiretroviral therapy (cART) management. Medication adherence of a subgroup of subjects was routinely monitored using an electronic device (MEMS(™) ). RESULTS: Eighty-eight subjects gave informed consent to participate in the study. The subjects' back-switch rate was 7% (six of 88). Subjects who did not back-switch preferred the one-tablet regimen (median = 2; IQR = 1.3-2.5; on a -3 to 3 scale), but no change in adherence was found (10 of 46 nonadherent subjects; P = 1.00). The perception of treatment necessity score decreased (P = 0.004), the efavirenz blood level increased (14%; P = 0.04), and association/dissociation of cART with food intake evolved (P = 0.01) after the switch. Subjects listed equivalent numbers of symptoms during the three visits. CONCLUSIONS: The one-tablet regimen was preferred but the number of back-switches was not negligible. The perception of treatment necessity score decreased with the simplification of the regimen from a two-tablet to a one-tablet formulation, which could negatively impact adherence. Switching is a sensitive time in a patient's treatment life and professionals should pay particular attention to patient's perceptions of treatment during such a transition.

Non-O1, non-O139 Vibrio cholerae (NOVC) are increasingly frequently observed ubiquitous microorganisms occasionally responsible for intestinal and extra-intestinal infections. Most cases involve self-limiting gastroenteritis or ear and wound infections in immunocompetent patients. Bacteraemia, which have been described in patients with predisposing factors, are rare and poorly known, both on the clinical and therapeutic aspects. We describe a case of NOVC bacteraemia and a systematic literature review in PubMed conducted up to November 2014 using a combination of the following search terms: "Vibrio cholerae non-O1" and "bacter(a)emia". The case was a 70 year-old healthy male subject returning from Senegal and suffering from NOVC bacteraemia associated with liver abscesses. Disease evolution was favourable after 2 months' therapy (ceftriaxone then ciprofloxacin). Three hundred and fifty cases of NOVC bacteraemia have been identified in the literature. The majority of patients were male (77 %), with a median age of 56 years and presenting with predisposing conditions (96 %), such as cirrhosis (55 %) or malignant disease (20 %). Diarrhoea was inconstant (42 %). Mortality was 33 %. The source of infection, identified in only 25 % of cases, was seafood consumption (54 %) or contaminated water (30 %). Practitioners should be aware of these infections, in order to warn patients with predisposing conditions, on the risk of ingesting raw or undercooked seafood or bathing in potentially infected waters.
ABSTRACT
BACKGROUND: Poor outcomes occur when patients with serious infections receive antibiotics to which the organisms are resistant. METHODS: Decision trees simulated in-hospital mortality, costs, incremental cost-effectiveness ratio per life year saved, and carbapenem resistance according to 3 empirical antibiotic strategies among adults hospitalized for community-acquired (CA) upper urinary tract infections (UTIs): ceftriaxone (CRO) plus gentamicin (GM) in the intensive care unit (ICU), imipenem (IMP), and individualized choice (IMP or CRO) based on clinical risk factors for CA- extended-spectrum ß-lactamase (ESBL). RESULTS: The estimated prevalence of CA-ESBL on admission was 5% (range, 1.3%-17.6%); 3% and 97% were admitted to the ICU and medical ward (MW), respectively. In the ICU, CRO plus GM was dominated; IMP was cost-effective (incremental cost-effectiveness ratio: 4,400 per life year saved compared with individualized choice). In the MW, IMP had no impact on mortality and was less costly (-142 per patient vs CRO, -38 vs individualized choice). The dominance of IMP was consistent in sensitivity analyses. Compared with CRO, colonization by carbapenem-resistant pathogens increased by an odds ratio of 4.5 in the IMP strategy. CONCLUSION: Among the ICU patients, empirical IMP therapy reduces mortality at an acceptable cost. Among MW patients, individualized choice or CRO is preferred to limit carbapenem resistance at a reasonable cost.

To avoid repeated apheresis, the objective of this study was to analyse the predictive factors for a single successful cytapheresis during the first mobilisation. The pre-collection characteristics of 170 lymphoma and 95 myeloma patients were analysed. Among 60 lymphoma patients who had less than 30 CD34 cells/mm(3) the day before the first apheresis, an increase in the CD34 cell count between Day -1 and Day 1 was predictive of first stem cell mobilisation success, with a sensitivity of 100% if the Day 1 was higher than 30/mm(3) (10/60 patients). Success rate of obtaining an appropriate number of stem cells in one apheresis was 120 among 170 patients.

Detection of microorganisms by blood cultures (BCs) is essential in managing patients with bacteraemia. Rather than the number of punctures, the volume of blood drawn is considered paramount in efficient and reliable detection of microorganisms. We performed a 1-year prospective multicentre study in adult emergency departments of three French university hospitals comparing two methods for BCs: a unique blood culture (UBC) collecting a large volume of blood (40 mL) and the standard method of multiple blood cultures (MBC). The performances of both methods for bacterial contamination and efficient microbial detection were compared, each patient serving as his own control. Amongst the 2314 patients included, three hundred were positive for pathogens (n=245) or contaminants (n=55). Out of the 245 patients, 11 were positive for pathogens by UBC but negative by MBC and seven negative by UBC but positive by MBC (p 0.480). In the subgroup of 137 patients with only two BCs, UBC was superior to MBC (p 0.044). Seven and 17 patients had contaminated BCs by UBC and MBC only, respectively (p 0.062). Considering the sums of pathogens missed and contaminants, UBC significantly outperformed MBC (p 0.045). Considering the complete picture of cost savings, efficient detection of microorganisms and decrease in contaminations, UBC offers an interesting alternative to MBC.

The purpose of this investigation was to evaluate the microbiological diagnosis yield of post-biopsy blood cultures (PBBCs) and second percutaneous needle biopsy (PNB) following an initial negative biopsy in vertebral osteomyelitis (VO) without bacteremia. A retrospective multicenter study was performed. Patients with VO, pre-biopsy negative blood culture(s), ≥1 PNB, and ≥1 PBBC (0-4 h) were included. One hundred and sixty-nine PNBs (136 first and 33 following initial negative biopsy) were performed for 136 patients (median age = 58 years, sex ratio M/F = 1.9). First and second PNBs had a similar yield: 43.4 % (59/136) versus 39.4 % (13/33), respectively. Only two PBBCs (1.1 %) led to a microbiological diagnosis. The strategy with positive first PNB and second PNB following an initial negative result led to microbiological diagnosis in 79.6 % (74/93) of cases versus 44.1 % (60/136) for the strategy with only one biopsy. In the multivariate analysis, young age (odds ratio, OR [95 % confidence interval (CI)] = 0.98 [0.97; 0.99] per 1 year increase, p = 0.02) and >1 sample (OR = 2.4 ([1.3; 4.4], p = 0.007)) were independently associated with positive PNB. To optimize microbiological diagnosis in vertebral osteomyelitis, performing a second PNB (after an initial negative biopsy) could lead to a microbiological diagnosis in nearly 80 % of patients. PBBC appears to be limited in microbiological diagnosis.

ABSTRACT
OBJECTIVE: Ventilator-associated pneumonia (VAP) is the most common hospital-acquired infection in intensive care unit (ICU). The aim of the study was to evaluate the follow-up of the guidelines for VAP prevention. STUDY DESIGN: Retrospective, observational and multicenter study. PATIENTS AND METHODS: During one year, all patients with mechanical ventilation over 48 hours were included in the CCLIN-Ouest Network. The demographic characteristics of the patients, the use of specific protocol for VAP prevention and the density of incidence of VAP were recorded. The use of a protocol for preventing VAP (absence, incomplete, complete and care bundle (i.e. complete prevention of VAP with weaning mechanical protocol and sedation protocol)) was collected. RESULTS: 26 ICU with 5742 patients were included. Ten ICU (38%; 2595 patients) had no protocol for VAP prevention, eight ICU (31%; 1821 patients) had an incomplete protocol, five ICU (19%; 561 patients) had a complete protocol and three ICU (12%; 765 patients) had a care bundle. The density of incidence of VAP was 14.8 (Interquartile range [IQR]: 10.2-0.1) for no protocol group, 15.6 [IQR: 12.6-6.2] for incomplete protocol group, 11.0 [IQR: 9.1-14.0] for complete protocol group and 12.9 [5-7,7-9,9-12] for care bundle group (P=0.742). CONCLUSIONS: The compliance to prevention of VAP was poor. Proposals for improving practice are discussed.

INTRODUCTION: Thirty-five to 40 days' thromboprophylaxis is recommended following total hip replacement (THR). Low molecular weight heparin (LMWH) injected by a health professional ensures good compliance. Compliance with recent oral anticoagulants has not been precisely assessed. Oral self-administration, without coagulation monitoring tests, may be a worrying issue in the management of what is a potentially catastrophic adverse event, without prodromal symptoms alerting the patient to the need for regular intake throughout the prescription period. HYPOTHESIS: It was hypothesized that compliance with these new oral anticoagulants is good over the entire treatment period. PATIENTS AND METHOD: The present cohort study prospectively assessed compliance with oral medication (two capsules of dabigatran etexilate [Pradaxa(®)] per day in a single dose at a set time) following THR. An electronic device continuously monitored the day and time of extraction of capsules from the package. All included patients underwent clinical and echo-Doppler examination at day 30±5 after the start of the study. RESULTS: Fifty-six patients were included at their discharge home. Overall compliance was 98.1% (3,188/3246 capsules correctly taken), falling off slightly over time but never below 97.1%. One patient was diagnosed with symptomatic thrombophlebitis 34 days postoperatively, associated with non-compliance at day 11. End of follow-up echo-Doppler found four cases of asymptomatic distal venous thrombosis. There were no hemorrhagic complications. DISCUSSION: The risk of thromboembolic complications diminishes over time, while oral anticoagulants have a wide therapeutic window and relatively long half-life (15-17 hrs). Efficacy was demonstrated, with improved patient comfort and cost-saving. Compliance in the present series was satisfactory. This, however, should not mean that patients not be appropriately informed, as in the present study, so as to improve compliance. LEVEL OF EVIDENCE: Level III, prospective diagnostic.

BACKGROUND: Septic shock remains a major cause of death in intensive care units (ICU) and an inappropriate antibiotic regimen worsens the prognosis. The aim of the study was to assess the impact of an information campaign on modalities of prescription of aminoglycosides in septic shock. STUDY DESIGN: A prospective observational study. METHODS: Consecutive septic shock patients admitted to the surgical ICU over a 2-year period were included. An information campaign allowed to differentiate between a pre- (P1) and a post- (P2) interventional period. The campaign clarified the rules and requirements for pharmacological monitoring of aminoglycosides. The main objective was to increase the rate of prescription of peak serum aminoglycoside following the first intravenous injection. RESULTS: One hundred and forty-eight patients (P1=76 and P2=72) were finally included into the study. Similar clinical characteristics were observed during both periods. The rate of prescription of peak serum aminoglycoside following the first injection was performed in 49% (P1) versus 65% (P2), P=0.09. The length of stay in ICU was 16 days [extremes: 1-74] (P1) versus 17 days [extremes: 1-133] (P2) (P=0.84). Inhospital mortality was 28% (P1) versus 26% (P2), P=0.86. CONCLUSIONS: An information campaign describing the modalities of prescription of aminoglycosides in septic shock failed to improve medical practices and patient outcomes. A mobile team of antibiotics could be useful in daily practice.
