Faecal carriage of multidrug-resistant bacteria and associated risk factors: results from a point prevalence study.

OBJECTIVES: Since 2003, incidences of carbapenemase-producing Gram-negative bacilli (CP-GNB) and vancomycin-resistant Enterococcus faecium (VRE) have steadily increased in France. We therefore conducted a point prevalence study to estimate carriage rates of CP-GNB, VRE and ESBL-producing Enterobacterales (ESBL-PE) and associated risk factors. METHODS: Between September 2019 and January 2020, all inpatients hospitalized on a given day in 11 teaching hospitals in the Paris urban area were eligible. Patient interviews and rectal swab screening results were recorded by dedicated nurses. The swabs were plated onto selective chromogenic media and processed using the GeneXpert® system. RESULTS: Of 2396 patients, 364 (15.2%) yielded at least one multiresistant bacterial isolate, including 29 CP-GNB carriers (1.2%), 13 VRE carriers (0.5%) and 338 ESBL-PE carriers (14%). In 15 patients (4.4% of ESBL-PE carriers and 36.6% of CP-GNB/VRE carriers), concomitant CP-GNB/VRE and ESBL-PE carriage was observed. In 7/29 CP-GNB and 7/13 VRE carriers, carbapenemase production and vanA in the screening samples was only detected with Xpert® tests. The OXA-48 gene was predominant in 13/34 CP-GNB isolates from 29 carriers. From the 338 ESBL-PE carriers, 372 isolates were recovered, mainly Escherichia coli (61.2%). Among 379 children, 1.1% carried a CP-GNB/VRE strain, and 12.4% carried an ESBL strain. Previous hospitalization outside mainland France, previous antimicrobial treatment and previous ESBL-PE carriage were the main risk factors associated with CP-GNB and/or VRE carriage. CONCLUSIONS: The low CP-GNB and VRE prevalence likely reflects the French policy to limit intrahospital spread of CP-GNB and VRE strains.

Appropriateness of empirical antibiotic prescription for bloodstream infections in an emergency department from 2006 to 2018: impact of the spread of ESBL-producing Enterobacterales.

The spread of ESBL producers in the community may impact the management of patients with bloodstream infections (BSI) involving Enterobacterales in emergency departments. Thus, from 2006 to 2018, data for all BSI episodes involving Enterobacterales from the emergency department of a French teaching hospital were retrospectively included. Antimicrobial susceptibility test results and empirical antibiotic regimens were recorded. Treatment was considered as appropriate if all isolates were susceptible in vitro to at least one prescribed antibiotic. A total of 1369 BSI episodes in 1321 patients was included. Urinary tract infection was the main source of BSI (61%). The prevalence of ESBL producers increased from zero to 9.2/100 Enterobacterales BSI cases (p < 0.001), mainly Escherichia coli (6.9 cases/100 BSI in 2018); and no Klebsiella. Third-generation cephalosporins (3GC) were used most frequently (71.8%) and their use as monotherapy increased during the study period (p < 0.001). The rate of appropriate treatment decreased from 95.8 to 89.2% (p = 0.023). Appropriateness of treatment was greater using two drugs vs one (97.3% vs 89.3%, p < 0.001). Treatments with 3GC were appropriate in 92% and 98.3%, when used alone or with another antibiotic, respectively (p < 0.001). Among inappropriate treatments, 45% concerned 3GC, with 74.6% of them attributable to ESBL production. The spread of ESBL producers in the community had a direct impact on the rate of inappropriate empirical treatment. Local antimicrobial resistance monitoring is required to optimize the management of BSI in emergency departments.

Effectiveness of a 'do not interrupt' vest intervention to reduce medication errors during medication administration: a multicenter cluster randomized controlled trial.

BACKGROUND: The use of a 'do not interrupt' vest during medication administration rounds is recommended but there have been no controlled randomized studies to evaluate its impact on reducing administration errors. We aimed to evaluate the impact of wearing such a vest on reducing such errors. The secondary objectives were to evaluate the types and potential clinical impact of errors, the association between errors and several risk factors (such as interruptions), and nurses' experiences. METHODS: This was a multicenter, cluster, controlled, randomized study (March-July 2017) in 29 adult units (4 hospitals). Data were collected by direct observation by trained observers. All nurses from selected units were informed. A 'Do not interrupt' vest was implemented in all units of the experimental group. A poster was placed at the entrance of these units to inform patients and relatives. The main outcome was the administration error rate (number of Opportunities for Error (OE), calculated as one or more errors divided by the Total Opportunities for Error (TOE) and multiplied by 100). RESULTS: We enrolled 178 nurses and 1346 patients during 383 medication rounds in 14 units in the experimental group and 15 units in the control group. During the intervention period, the administration error rates were 7.09% (188 OE with at least one error/2653 TOE) for the experimental group and 6.23% (210 OE with at least one error/3373 TOE) for the control group (p = 0.192). Identified risk factors (patient age, nurses' experience, nurses' workload, unit exposition, and interruption) were not associated with the error rate. The main error type observed for both groups was wrong dosage-form. Most errors had no clinical impact for the patient and the interruption rates were 15.04% for the experimental group and 20.75% for the control group. CONCLUSIONS: The intervention vest had no impact on medication administration error or interruption rates. Further studies need to be performed taking into consideration the limitations of our study and other risk factors associated with other interventions, such as nurse's training and/or a barcode system. TRIAL REGISTRATION: The PERMIS study protocol (V2-1, 11/04/2017) was approved by institutional review boards and ethics committees (CPP Ile de France number 2016-A00211-50, CNIL 21/03/2017, CCTIRS 11/04/2016). It is registered at ClinicalTrials.gov (registration number: NCT03062852 , date of first registration: 23/02/2017).

EMERGEncy versus delayed coronary angiogram in survivors of out-of-hospital cardiac arrest with no obvious non-cardiac cause of arrest: Design of the EMERGE trial.

BACKGROUND: In adults, the most common cause of out-of-hospital cardiac arrests (OHCA) is acute coronary artery occlusion. If an immediate coronary angiogram (CAG) is recommended for survivors presenting a ST segment elevation on the electrocardiogram (ECG) performed after resuscitation, there is still a debate regarding the best strategy in patients without ST segment elevation. HYPOTHESIS: Performing an immediate CAG after an OHCA without ST segment elevation on the post-resuscitation ECG and no obvious non-cardiac cause of arrest could lead to a better 180-day survival rate with no or minimal neurological sequel as compared with a delayed CAG performed 48 to 96 hours after the arrest. DESIGN: The EMERGE trial is a prospective national, randomized, open and parallel group trial, in which 970 survivors of OHCA will be randomized (1:1) to either immediate (as soon as possible after return of spontaneous circulation) or delayed (48 to 96 h) CAG. Participants will be OHCA patients with no ST segment elevation on the post resuscitation ECG and no obvious non-cardiac cause of arrest. The primary endpoint of the study is the 180-day survival rate with no or minimal neurological sequel corresponding to Cerebral Performance Category (CPC) 1 or 2. The secondary endpoints are: occurrence of shock during the first 48 hours, ventricular tachycardia and/or fibrillation during the first 48 hours, change in left ventricular ejection fraction between baseline and 180 days assessed by echocardiogram, neurological status evaluated by the CPC score at intensive care unit (ICU) discharge and day 90 neurological status assessed by the Glasgow Outcome Scale Extended score (GOSE) at 90 and 180 days, overall survival rate, and hospital length of stay. SUMMARY: The EMERGE trial is a prospective, multicenter, randomized, controlled trial that will assess the 180-day survival rate with no or minimal neurologic sequel in patients resuscitated from an OHCA without ST segment elevation and who will be managed with either immediate or delayed CAG.

Multicentre analysis of intensity of care at the end-of-life in patients with advanced cancer, combining health administrative data with hospital records: variations in practice call for routine quality evaluation.

BACKGROUND: Accessible indicators of aggressiveness of care at the end-of-life are useful to monitor implementation of early integrated palliative care practice. To determine the intensity of end-of-life care from exhaustive data combining administrative databases and hospital clinical records, to evaluate its variability across hospital facilities and associations with timely introduction of palliative care (PC). METHODS: For this study designed as a decedent series nested in multicentre cohort of advanced cancer patients, we selected 997 decedents from a cohort of patients hospitalised in 2009-2010, with a diagnosis of metastatic cancer in 3 academic medical centres and 2 comprehensive cancer centres in the Paris area. Hospital data was combined with nationwide mortality databases. Complete data were collected and checked from clinical records, including first referral to PC, chemotherapy within 14 days of death, ≥1 intensive care unit (ICU) admission, ≥2 emergency department visits (ED), and ≥ 2 hospitalizations, all within 30 days of death. RESULTS: Overall (min-max) indicator values as reported by facility providing care rather than the place of death, were: 16% (8-25%) patients received chemotherapy within 14 days of death, 16% (6-32%) had ≥2 admissions to acute care, 6% (0-15%) had ≥2 emergency visits and 18% (4-35%) had ≥1 intensive care unit admission(s). Only 53% of these patients met the PC team, and the median (min-max) time between the first intervention of the PC team and death was 41 (17-112) days. The introduction of PC > 30 days before death was independently associated with lower intensity of care. CONCLUSIONS: Aggressiveness of end-of-life cancer care is highly variable across centres. This validates the use of indicators to monitor integrated PC in oncology. Disseminating a quality audit-feedback cycle should contribute to a shared view of appropriate end-of-life care objectives, and foster action for improvement among care providers.

Early versus delayed coronary angiography in patients with out-of-hospital cardiac arrest and no ST-segment elevation: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Recent randomized controlled trials did not show benefit of early/immediate coronary angiography (CAG) over a delayed/selective strategy in patients with out-of-hospital cardiac arrest (OHCA) and no ST-segment elevation. However, whether selected subgroups, specifically those with a high pretest probability of coronary artery disease may benefit from early CAG remains unclear. METHODS: We included all randomized controlled trials that compared a strategy of early/immediate versus delayed/selective CAG in OHCA patients and no ST elevation and had a follow-up of at least 30 days. The primary outcome of interest was all-cause death. Odds ratios (OR) were calculated and pooled across trials. Interaction testing was used to assess for heterogeneity of treatment effects. RESULTS: In total, 1512 patients (67 years, 26% female, 23% prior myocardial infarction) were included from 5 randomized controlled trials. Early/immediate versus delayed/selective CAG was not associated with a statistically significant difference in odds of death (OR 1.12, 95%-CI 0.91-1.38), with similar findings for the composite outcome of all-cause death or neurological deficit (OR 1.10, 95%-CI 0.89-1.36). There was no effect modification for death by age, presence of a shockable initial cardiac rhythm, history of coronary artery disease, presence of an ischemic event as the presumed cause of arrest, or time to return of spontaneous circulation (all P-interaction > 0.10). However, early/immediate CAG tended to be associated with higher odds of death in women (OR 1.52, 95%-CI 1.00-2.31, P = 0.050) than in men (OR 1.04, 95%-CI 0.82-1.33, P = 0.74; P-interaction 0.097). CONCLUSION: In OHCA patients without ST-segment elevation, a strategy of early/immediate versus delayed/selective CAG did not reduce all-cause mortality across major subgroups. However, women tended to have higher odds of death with early CAG.

MyGood Trip, a Telemedicine Intervention for Physical Activity Recovery After Bariatric Surgery: Randomized Controlled Trial.

BACKGROUND: Despite bariatric surgery showing significant weight loss trajectories for many patients, a substantial proportion regain weight after the first year following surgery. The addition of telemedicine to standard care could support patients with engaging in a more active lifestyle and thus improve clinical outcomes. OBJECTIVE: Our aim was to evaluate a telemedicine intervention program dedicated to the promotion of physical activity including digital devices, teleconsultation, and telemonitoring the first 6 months following bariatric surgery. METHODS: This study employed a mixed methods design based on an open-label randomized controlled trial. Patients were included during the first week after bariatric surgery; then, they were randomized into 2 intervention groups: The TelePhys group received a monthly telemedicine consultation focusing on physical activity coaching, while the TeleDiet group received a monthly telemedicine consultation involving diet coaching. Data were collected using a watch pedometer and body weight scale, both of which were connected wirelessly. The primary outcome was the difference between the 2 groups in the mean numbers of steps at the first and sixth postoperative months. Weight change was also evaluated, and focus groups and interviews were conducted to enrich the results and capture perceptions of the telemedicine provided. RESULTS: Among the 90 patients (mean age 40.6, SD 10.4 years; 73/90, 81% women; 62/90, 69% gastric bypass), 70 completed the study until the sixth month (n=38 TelePhys; n=32 TeleDiet), and 18 participants agreed to be interviewed (n=8 Telephys; n=10 TeleDiet). An increase in the mean number of steps between the first and sixth months was found in both groups, but this change was significant only in the TeleDiet group (P=.01). No difference was found when comparing both intervention groups. Interviewed participants reported having appreciated the teleconsultations, as the individualized tailored counseling helped them to make better choices about behaviors that could increase their likelihood of a daily life in better health. Weight loss followed by social factors (such as social support) were identified as the main facilitators to physical activity. Family responsibilities, professional constraints as well as poor urban policies promoting physical activity, and lack of accessibility to sport infrastructure were their major barriers to postoperative lifestyle adherence. CONCLUSIONS: Our study did not show any difference in mobility recovery after bariatric surgery related to a telemedicine intervention dedicated to physical activity. The early postoperative timing for our intervention may explain the null findings. eHealth interventions aiming to change behaviors and carried out by clinicians require support from structured public health policies that tackle patients' obesogenic environment in order to be efficient in their struggle against sedentary lifestyle-related pathologies. Further research will need to focus on long-term interventions. TRIAL REGISTRATION: ClinicalTrials.gov NCT02716480, https://clinicaltrials.gov/ct2/show/NCT02716480.

Early versus deferred coronary angiography following cardiac arrest. A systematic review and meta-analysis.

Aim: The role of early coronary angiography (CAG) in the evaluation of patients presenting with out of hospital cardiac arrest (OHCA) and no ST-elevation myocardial infarction (STE) pattern on electrocardiogram (ECG) has been subject to considerable debate. We sought to assess the impact of early versus deferred CAG on mortality and neurological outcomes in patients with OHCA and no STE. Methods: OVID MEDLINE, EMBASE, Web of Science and Cochrane Library Register were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines from inception until July 18, 2022. Randomized clinical trials (RCTs) of patients with OHCA without STE that compared early CAG with deferred CAG were included. The primary endpoint was 30-day mortality. Secondary endpoints included mortality at discharge or 30-days, favourable neurology at 30-days, major bleeding, renal failure and recurrent cardiac arrest. Results: Of the 7,998 citations, 5 RCTs randomizing 1524 patients were included. Meta-analysis showed no difference in 30-day mortality with early versus deferred CAG (OR 1.17, CI 0.91 - 1.49, I2 = 27%). There was no difference in favourable neurological outcome at 30 days (OR 0.88, CI 0.52 - 1.49, I2 = 63%), major bleeding (OR 0.94, CI 0.33 - 2.68, I2 = 39%), renal failure (OR 1.14, CI 0.77 - 1.69, I2 = 0%), and recurrent cardiac arrest (OR 1.39, CI 0.79 - 2.43, I2 = 0%). Conclusions: Early CAG was not associated with improved survival and neurological outcomes among patients with OHCA without STE. This meta-analysis does not support routinely performing early CAG in this select patient cohort.

Prevalence and risk factors of toxigenic Clostridioides difficile asymptomatic carriage in 11 French hospitals.

Clostridioides difficile infection (CDI) incidence has increased over the last 20 years. Studies suggest that asymptomatic carriers may be an important reservoir of C. difficile in healthcare settings. We conducted a point prevalence study to estimate the toxigenic C. difficile asymptomatic carriage rate and the associated risk factors in patients >3 years old. Between September 16, 2019 and January 15, 2020, all patients hospitalized in 11 healthcare facilities in the Paris urban area were included in the study. They were screened on the day of the survey for toxigenic C. difficile carriage by rectal swab and interviewed. Isolates were characterized by PCR ribotyping and multiplex PCR targeting toxin genes. A logistic regression model was used to determine the risk factors associated with toxigenic C. difficile asymptomatic carriage using uni- and multivariate analysis in the subpopulation of patients >3 years old. During the study period, 2,389 patients were included and screened. The median age was 62 years (interquartile range 35-78 years) and 1,153 were male (48.3%). Nineteen patients had a previous CDI (0.9%). Overall, 185/2389 patients were positive for C. difficile (7.7%), including 93 toxigenic strains (3.9%): 77 (82.8%) were asymptomatic (prevalence 3.2%) whereas 12 (12.9%) were diarrheic. Prevalences of toxigenic C. difficile were 3.5% in patients >3 years old and 7.0% in ≤3 years old subjects, respectively. Toxigenic strains mainly belonged to PCR ribotypes 106 (n = 14, 15.0%), 014 (n = 12, 12.9%), and 020 (n = 10, 10.8%). Among toxigenic strains, 6 (6.4%) produced the binary toxin. In multivariate analysis, two factors were positively associated with toxigenic C. difficile asymptomatic carriage in patients >3 years old: multidrug-resistant organisms co-carriage [adjusted Odd Ratio (aOR) 2.3, CI 95% 1.2-4.7, p = 0.02] and previous CDI (aOR 5.8, CI 95% 1.2-28.6, p = 0.03). Conversely, consumption of raw milk products were associated with reduced risk of toxigenic C. difficile colonization (aOR 0.5, CI 95% 0.2-0.9, p = 0.01). We showed that there was a low prevalence of asymptomatic toxigenic C. difficile carriage in hospitalized patients. Consumption of raw milk prevents toxigenic C. difficile colonization, probably due to the barrier effect of milk-associated bacteria.

Practice patterns for chronic hypoparathyroidism: data from patients and physicians in France.

Context: Recent guidelines have provided recommendations for the care of patients with chronic hypoparathyroidism. Very little is known about actual physicians' practices or their adherence to such guidelines. Objective: To describe the physicians' practice patterns and their compliance with international guidelines. Design: The cohort studies included were Épi-Hypo (118 physicians and 107 patients, from September 2016 to December 2019) and ePatients (110 patients, November 2019). Methods: Internet-based cohorts involving all settings at a nationwide level (France). Participants were (i) physicians treating patients with chronic hypoparathyroidism and patients with chronic hypoparathyroidism either participating in the (ii) Épi-Hypo study (Épi-Hypo 2019 patients), or (iii) Hypoparathyroidism France, the national representative association (ePatients). Results: The physicians' specialties were mainly endocrinology (61%), nephrology (28%), family medicine (2.5%), pediatrics (2.5%), rheumatology (2%), or miscellaneous (4%) and 45% were practicing in public universities. The median number of pharmaceutical drug classes prescribed was three per patient. The combination of active vitamin D and calcium salt was given to 59 and 58% of ePatients and Épi-Hypo 2019 patients, respectively. Eighty-five percent of ePatients and 87% of physicians reported monitoring plasma calcium concentrations at a steady state at least twice a year. In 32 and 26% of cases, respectively, ePatients and physicians reported being fully in accordance with international guidelines that recommend targeting symptoms, plasma calcium and phosphate values, and urine calcium excretion. Conclusions: The care of patients with chronic hypoparathyroidism involves physicians with very different practices, so guidelines should include and target other specialists as well as endocrinologists. Full adherence to the guidelines is low in France.

Emergency vs Delayed Coronary Angiogram in Survivors of Out-of-Hospital Cardiac Arrest: Results of the Randomized, Multicentric EMERGE Trial.

Importance: Although an emergency coronary angiogram (CAG) is recommended for patients who experience an out-of-hospital cardiac arrest (OHCA) with ST-segment elevation on the postresuscitation electrocardiogram (ECG), this strategy is still debated in patients without ST-segment elevation. Objective: To assess the 180-day survival rate with Cerebral Performance Category (CPC) 1 or 2 of patients who experience an OHCA without ST-segment elevation on ECG and undergo emergency CAG vs delayed CAG. Design, Setting, and Participants: The Emergency vs Delayed Coronary Angiogram in Survivors of Out-of-Hospital Cardiac Arrest (EMERGE) trial randomly assigned survivors of an OHCA without ST-segment elevation on ECG to either emergency or delayed (48 to 96 hours) CAG in 22 French centers. The trial took place from January 19, 2017, to November 23, 2020. Data were analyzed from November 24, 2020, to July 30, 2021. Main Outcomes and Measures: The primary outcome was the 180-day survival rate with CPC of 2 or less. The secondary end points were occurrence of shock, ventricular tachycardia, and/or fibrillation within 48 hours, change in left ventricular ejection fraction between baseline and 180 days, CPC scale at intensive care unit discharge and day 90, survival rate, and hospital length of stay. Results: A total of 279 patients (mean [SD] age, 64.7 [14.6] years; 195 men [69.9%]) were enrolled, with 141 (50.5%) in the emergency CAG group and 138 (49.5%) in the delayed CAG group. The study was underpowered. The mean (SD) time delay between randomization and CAG was 0.6 (3.7) hours in the emergency CAG group and 55.1 (37.2) hours in the delayed CAG group. The 180-day survival rates among patients with a CPC of 2 or less were 34.1% (47 of 141) in the emergency CAG group and 30.7% (42 of 138) in the delayed CAG group (hazard ratio [HR], 0.87; 95% CI, 0.65-1.15; P = .32). There was no difference in the overall survival rate at 180 days (emergency CAG, 36.2% [51 of 141] vs delayed CAG, 33.3% [46 of 138]; HR, 0.86; 95% CI, 0.64-1.15; P = .31) and in secondary outcomes between the 2 groups. Conclusions and Relevance: In this randomized clinical trial, for patients who experience an OHCA without ST-segment elevation on ECG, a strategy of emergency CAG was not better than a strategy of delayed CAG with respect to 180-day survival rate and minimal neurologic sequelae.

"Ranger BTK" a Prospective Single-Centre Cohort Study on a New Drug-Coated Balloon for Below the Knee Lesions in Patients with Critical Limb Ischemia.

PURPOSE: Restenosis remains a limitation of endovascular angioplasty with a patency of 30% in BTK at 12 months. Several studies on drug-coated balloons have not demonstrated any improvements in terms of patency and target lesions revascularization in BTK lesions. This prospective single-centre cohort study evaluates the safety and efficacy of a new generation low-dose drug-coated balloon (DCB) with a reduced crystalline structure to treat below the knee (BTK) lesions in patients with critical limb ischemia (CLI). MATERIALS AND METHODS: Between November 2016 and November 2017, 30 consecutive patients (mean 68.8 ± 12.7 years, 6 female) with BTK lesions and CLI were included in this single-centre, prospective non-randomized cohort study. All patients with rest pain and/or ischemic wound associated with BTK lesions were included in the study. Mean lesion length was 133.6 ± 94.5 mm and 18(60%) were chronic total occlusions. The primary safety outcome parameter was a composite of all-cause mortality and major amputation at 6 months. The primary efficacy outcome parameter was the primary angiographic patency at 6 months (defined as freedom from clinically driven target lesion revascularization and the absence of significant restenosis (> 50%) as determined by core laboratory angiography assessment. Immediate technical success, late lumen loss (LLL), clinical target lesion revascularization (TLR) and ulcer healing rates at 12 months were also evaluated. RESULTS: Immediate technical success was 97%(29/30): one patient had an acute thrombosis at the completion of index procedure. Primary safety outcome parameter was 94%(28/30): one patient underwent major amputation and one patient died of other comorbidities at 2 months. Another patient had a major amputation at 7.5 months. Angiographic follow-up was available in 20 patients. Primary angiographic patency was 57%(12/21 lesions), and LLL was 0.99 ± 0.68 mm at 6 months. Freedom from TLR was 89% at 12 months. The rate of ulcer healing was 76% at 12 months. CONCLUSION: Ranger DCB balloons to treat CLI patients demonstrated a positive trend with good safety outcomes parameters. Further randomized studies are needed to understand the usefulness compared to POBA.

Integration of a Commercial Barcode-Assisted Medication Dispensing System in a Teaching Hospital.

OBJECTIVES: A commercial barcode-assisted medication administration (BCMA) system was integrated to secure the medication process and particularly the dispensing stage by technicians and the administration stage with nurses. We aimed to assess the impact of this system on medication dispensing errors and barriers encountered during integration process. METHODS: We conducted a controlled randomized study in a teaching hospital, during dispensing process at the pharmacy department. Four wards were randomized in the experimental group and control group, with two wards using the system during 3 days with dedicated pharmacy technicians. The system was a closed loop system without information return to the computerized physician order entry system. The two dedicated technicians had a 1-week training session. Observations were performed by one observer among the four potential observers previously trained. The main outcomes assessed were dispensing error rates and the identification of barriers encountered to expose lessons learned from this study. RESULTS: There was no difference between the dispensing error rate of the control and experimental groups (7.9% for both, p = 0.927). We identified 10 barriers to pharmacy barcode-assisted system technology deployment. They concerned technical (problems with semantic interoperability interfaces, bad user interface, false errors generated, lack of barcodes), structural (poor integration with local information technology), work force (short staff training period, insufficient workforce), and strategic issues (system performance problems, insufficient budget). CONCLUSION: This study highlights the difficulties encountered in integrating a commercial system in current hospital information systems. Several issues need to be taken into consideration before the integration of a commercial barcode-assisted system in a teaching hospital. In our experience, interoperability of this system with the electronic health record is the key for the success of this process with an entire closed loop system from prescription to administration. BCMA system at the dispensing process remains essential to purchase securing medication administration process.

Dynamic magnetic resonance imaging in unilateral diaphragm eventration: knowledge improvement before and after plication.

BACKGROUND: The assessment before surgical plication for unilateral hemidiaphragm (HD) eventration is not clearly defined and no precise criteria exist to really understand which patient is operated with which results depending on the technique used. The goal of this study was to evaluate the place of dynamic magnetic resonance imaging (dMRI) before and after plication by developing measurement criteria. METHODS: Between 2006 and 2017, 18 patients (group1: Gp1) were operated for eventrations, 15 left-sided (Gp1L) and 3 right-sided (Gp1R). All had preoperative and postoperative evaluations including dMRI and pulmonary function tests. Five healthy volunteer subjects (group2: Gp2) had the same imaging protocol. For each HD, we measured the respiratory excursion at three fixed points (S1, S2, S3) and the height of curvature on sagittal plane. We also searched for upward paradoxical diaphragm movements. RESULTS: Before surgery, no excursion (n=13) or extremely reduced excursion (n=5) was detected on the injured HD (IHD) in Gp1. Upward paradoxical movements were identified only in Gp1L (n=6). Compared with Gp2 subjects, the healthy HD for Gp1L patients had significantly reduced excursion values at three sites S1 (P=0.038), S2 (P=0.006), and S3 (P=0.004). After plication, the decreasing height of curvature confirmed a tightening of the IHD in all patients (median value from 100 to 39.5 mm in Gp1L and 92 to 74 mm in Gp1R, P=0.0001). All upward paradoxical movements disappeared. Healthy HD excursions in Gp1L normalised their values. All those imaging improvements were correlated with postoperative improvements of dyspnoea score (P<0.0001) and vital capacity (P=0.002). CONCLUSIONS: dMRI and the standardised grid we developed not only improve the knowledge of unilateral diaphragm eventration but also permit to evaluate the quality of its surgical repair. It also demonstrates that a dysfunction of the healthy HD contralateral to eventration is possible and reversible after plication of the IHD.
