Background: Urinary tract infections (UTIs) are among the most common bacterial infections. Despite this burden, there are few studies of the costs of UTIs. The objective of this study was to determine the costs of UTIs in women over 18 years of age who visit general practitioners in France.Methods: The direct and indirect costs of clinical UTIs were estimated from societal, French National Health Insurance and patient perspectives. The study population was derived from a national cross-sectional survey entitled the Drug-Resistant Urinary Tract Infection (Druti). The Druti included every woman over 18 years of age who presented with symptoms of UTI and was conducted in France in 2012 and 2013 to estimate the annual incidence of UTIs due to antibiotic-resistant Enterobacteriaceae in women visiting general practitioners (GPs) for suspected UTIs.Results: Of the 538 women included in Druti, 460 were followed over 8 weeks and included in the cost analysis. The mean age of the women was 46 years old. The median cost of care for one episode of a suspected UTI was €38, and the mean cost was €70. The annual societal cost was €58 million, and €29 million of this was reimbursed by the French National Health Insurance system. In 25 % of the cases, the suspected UTIs were associated with negative urine cultures. The societal cost of these suspected UTIs with negative urine cultures was €13.5 million. No significant difference was found between the costs of the UTIs due to antibiotic-resistant E. coli and those due to wild E. coli (p = 0.63).Conclusion: In the current context in which the care costs are continually increasing, the results of this study suggests that it is possible to decrease the cost of UTIs by reducing the costs of suspected UTIs and unnecessary treatments, as well as limiting the use of non-recommended tests.

- Abstract
Objectives: This study aimed to evaluate the cost-effectiveness of introducing tofacitinib in second-line therapies after methotrexate failure for rheumatoid arthritis in France., Methods: Using a Markov model, we simulated a cohort of 10,000 patients based on literature data to compare various treatment strategies. The reference strategy included the four classes of biologics commonly used in France (TNFi, tocilizumab, abatacept, rituximab). The trial strategies additionally included tofacitinib at different introduction positions. The cycle duration was set at 6 months, and the time horizon was a lifetime. The data for severe adverse effects were sourced from the ORAL Surveillance study., Results: Compared to the reference strategy, introducing tofacitinib is a dominant strategy, regardless of its introduction position. Introducing it as the first-line treatment results in the greatest cost savings (€1,679 per patient) while increasing quality-adjusted life years (QALYs) by 0.29. According to the one-way sensitivity analysis, the discount rate and the cost of TNFi were the two variables that most influenced costs, while the change in HAQ score and the discount rate were the two variables that most influenced QALYs., Conclusions: Our study represents the first assessment of the cost-effectiveness of tofacitinib in France and incorporates the latest adverse effects reported in the literature. It reinforces previously obtained results from other countries. Our study has some limitations, mainly related to the use of data from clinical trials. Our analysis is limited to severe adverse effects, and their cost is extrapolated from the average hospitalisation cost. The estimated costs are therefore underestimated for chronic diseases such as cancer.

- Abstract
Background: Lower limb osteoarthritis (OA) often generates musculoskeletal pain causing functional impairment and decreasing mobility, autonomy, and quality of life. Patients with OA are commonly prescribed specific care for total hip arthroplasty or total knee arthroplasty (THA or TKA), when patients present symptoms that are refractory to nondrug treatments. Currently, when patients are discharged from orthopedic surgery, they are either referred to a rehabilitation department, or sent directly home with assistance such as remote monitoring by teleconsultation or a mobile application. In recent years, there has been an evolution in digital health and in particular telerehabilitation. To determine utility and effectiveness, the aim of this systematic review was to highlight and evaluate different telerehabilitation programs using new information and communication technologies. Methods: Five databases, ScienceDirect, PubMed, Web of Sciences, Scopus, and Google scholar, were searched until 30 June 30, 2023. All studies written in English and meeting our inclusion criteria were included. Databases were screened for "Total Hip Arthroplasty," "Total Knee Arthroplasty," "Total Hip Replacement," "Total Knee Replacement," "Rehabilitation," "Physical Activity," "Physiotherapy," "Telerehabilitation," "Telecommunication*," "Senior*," and "Elderly" in accordance with PRISMA-ScR guideline. Results: Fourteen articles were selected according to inclusion criteria. Telerehabilitation was offered in seven different ways (video call, applications smartphones, website, etc.). Assessments included were mainly quality of life questionnaires, perceived effort after exercises, field surveys on the tool experience, and physical tests to assess motor functions. Conclusion: This review highlights the importance and relevance of evaluating the contributions and limits of new health technologies to improve patient monitoring and thus enable better remote clinical care.

- Abstract
Background: In young children, respiratory syncytial virus (RSV)-related bronchiolitis is typically more severe than other respiratory tract infections, with a greater need for oxygen therapy and respiratory support. Few studies have compared the cost of hospitalization with regard to virological status. The objective of this study was to compare the costs of hospitalization for RSV-positive vs. RSV-negative bronchiolitis in a French university medical center between 2010 and 2015., Methods: The cost models were compared using conventional goodness-of-fit criteria. Covariates included the characteristics of the patients, pre-existing respiratory and non-respiratory comorbidities, superinfections, medical care provided, and the length of stay., Results: RSV was detected in 679 (58.3%) of the 1,164 hospital stays by children under 2 years with virological data. Oxygen therapy and respiratory support were twice as frequent for the RSV-positive cases. The median hospitalization cost was estimated at €3,248.4 (interquartile range: €2,572.1). The cost distribution was positively skewed with a variation coefficient (CV = standard deviation/mean) greater than one (mean = €4,212.9, standard deviation = €5,047, CV = 1.2). In univariate analyses, there was no significant cost difference between the RSV-positive and RSV-negative cases. In the best multivariate model, the significant positive effect of RSV positivity on cost waned after the introduction of medical care variables and the length of stay. The results were sensitive to the specification of the model., Conclusions: It was impossible to firmly conclude that hospitalization costs were higher for the RSV-positive cases., Competing Interests: FD reports fees since 2021 as expert in a board headed by Sanofi-Pasteur about RSV passive immunotherapy. Outside the submitted work, FD also reports academic grants and fees as expert in boards headed by Takeda and MSD. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Dervaux, Van Berleere, Lenne, Wyckaert and Dubos.)

- Abstract
Background: Respiratory syncytial virus (RSV) causes a considerable disease burden in young children globally, but reliable estimates of RSV-related costs and health-related quality-of-life (HRQoL) are scarce. This study aimed to evaluate the RSV-associated costs and HRQoL effects in infants and their caregivers in four European countries., Methods: Healthy term-born infants were recruited at birth and actively followed up in four European countries. Symptomatic infants were systematically tested for RSV. Caregivers recorded the daily HRQoL of their child and themselves, measured by a modified EQ-5D with Visual Analogue Scale, for 14 consecutive days or until symptoms resolved. At the end of each RSV episode, caregivers reported healthcare resource use and work absenteeism. Direct medical costs per RSV episode were estimated from a healthcare payer's perspective and indirect costs were estimated from a societal perspective. Means and 95% confidence intervals (CI) of direct medical costs, total costs (direct costs + productivity loss) and quality-adjusted life-day (QALD) loss per RSV episode were estimated per RSV episode, as well as per subgroup (medical attendance, country)., Results: Our cohort of 1041 infants experienced 265 RSV episodes with a mean symptom duration of 12.5 days. The mean (95% CI) cost per RSV episode was €399.5 (242.3, 584.2) and €494.3 (317.7, 696.1) from the healthcare payer's and societal perspective, respectively. The mean QALD loss per RSV episode of 1.9 (1.7, 2.1) was independent of medical attendance (in contrast to costs, which also differed by country). Caregiver and infant HRQoL evolved similarly., Conclusion: This study fills essential gaps for future economic evaluations by prospectively estimating direct and indirect costs and HRQoL effects on healthy term infants and caregivers separately, for both medically attended (MA) and non-MA laboratory-confirmed RSV episodes. We generally observed greater HRQoL losses than in previous studies which used non-community and/or non-prospective designs., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: 'PB reported consulting fees from Pfizer, GSK on 2 occasions for discussions on economic evaluation, for a total of <€3000 combined, paid 100% directly to the University of Antwerp.

- Abstract
Within the life-cycle assessment of health technologies, real-world data (RWD) have until now been of secondary importance to clinical trial data. The availability of massive, better quality RWD, particularly with the emergence of connected devices, the improvement of methods for characterizing populations, make it possible to have a better insight into the effects of treatment, sometimes on a national scale the importance of RWD is likely to progress in the eyes of health technology assessors, going from being traditionally complementary to possibly replacing clinical trial data. This is the fundamental question that the round table, involving experts from the academic and/or hospital, institutional, and industrial worlds, set out to answer. This work served first to establish the current role of RWD in health technology assessment, by distinguishing the main purposes of RWD, the timing of the evaluation in relation to the life cycle of the technology, and then according to the party commissioning or receiving the outcomes of RWD-based studies. Secondly, the round table proposed six general recommendations for more intensive and decisive use of RWD in the assessment and decision-making process., (Copyright © 2022 Société française de pharmacologie et de thérapeutique.

- Abstract
Background: Since the beginning of the COVID-19 pandemic, many countries, including Canada, have adopted unprecedented physical distancing measures such as closure of schools and non-essential businesses, and restrictions on gatherings and household visits. We described time trends in social contacts for the pre-pandemic and pandemic periods in Quebec, Canada., Methods: CONNECT is a population-based study of social contacts conducted shortly before (2018/2019) and during the COVID-19 pandemic (April 2020 - February 2021), using the same methodology for both periods. We recruited participants by random digit dialing and collected data by self-administered web-based questionnaires. Questionnaires documented socio-demographic characteristics and social contacts for two assigned days. A contact was defined as a two-way conversation at a distance ≤ 2 m or as a physical contact, irrespective of masking. We used weighted generalized linear models with a Poisson distribution and robust variance (taking possible overdispersion into account) to compare the mean number of social contacts over time and by socio-demographic characteristics., Results: A total of 1291 and 5516 Quebecers completed the study before and during the pandemic, respectively. Contacts significantly decreased from a mean of 8 contacts/day prior to the pandemic to 3 contacts/day during the spring 2020 lockdown. Contacts remained lower than the pre-COVID period thereafter (lowest = 3 contacts/day during the Christmas 2020/2021 holidays, highest = 5 in September 2020). Contacts at work, during leisure activities/in other locations, and at home with visitors showed the greatest decreases since the beginning of the pandemic. All sociodemographic subgroups showed significant decreases of contacts since the beginning of the pandemic. The mixing matrices illustrated the impact of public health measures (e.g. school closure, gathering restrictions) with fewer contacts between children/teenagers and fewer contacts outside of the three main diagonals of contacts between same-age partners/siblings and between children and their parents., Conclusion: Physical distancing measures in Quebec significantly decreased social contacts, which most likely mitigated the spread of COVID-19., (© 2022.

- Abstract
Objectives: For medical devices, a usability assessment is mandatory for market access; the objective is to detect potentially harmful use errors that stem from the device's design. The manufacturer assesses the final version of the device and determines the risk-benefit ratio for remaining errors. Nevertheless, the decision rule currently used to determine the sample size for this testing has statistical limitations and the lack of a clear decision-making perspective., Methods: As an alternative, we developed a value-of-information analysis from the medical device manufacturer's perspective. The consequences of use errors not detected during usability testing and the errors' probability of occurrence were embedded in a loss function. The value of further testing was assessed as a reduction in the expected loss for the manufacturer. The optimal sample size was determined using the expected net benefit of sampling (ENBS) (the difference between the value provided by new participants and the cost of their inclusion)., Results: The value-of-information approach was applied to a real usability test of a needle-free adrenaline autoinjector. The initial estimate (performed on the first n = 20 participants) gave an optimal sample size of 100 participants and an ENBS of €255 453. This estimation was updated iteratively as new participants were included. After the inclusion of 90 participants, the ENBS was null for any sample size; hence, the cost of adding more participants outweighed the expected value of information, and therefore, the study could be stopped., Conclusions: On the basis of these results, our method seems to be highly suitable for sample size estimation in the usability testing of medical devices before market access., (Copyright © 2021 International Society for Pharmacoeconomics and Outcomes Research, Inc.

- Abstract
Background: Endovascular treatment has become the first-line revascularization technique for femoropopliteal lesions. This technique lacks reliable and accurate morphological control of the arterial segment treated. Intraoperative 2-dimensional angiogram consumes iodinated contrast media and increases X-ray exposure; this subsequently provides no 3-dimensional information on the quality of the revascularization completed, what could explain some of the early and late failures of the technique. We evaluated whether intraoperative optical coherence tomography (OCT) control in addition to standard angiogram could improve the primary patency rate at 12 months in comparison to standard angiogram alone in patients with occlusive femoropopliteal lesions., Methods: The tomography by optical coherence in femoral artery trial is a multicentric, prospective, randomized, controlled, and single-blind study including patients with long de novo occlusive femoropopliteal lesions. The randomization will be achieved in 2 balanced groups of patients after crossing successfully the lesion: group 1 with intraoperative OCT control in addition to standard angiogram and group 2 with standard angiogram alone. The randomization will be stratified by center. The protocol has been submitted and approved by a French ethic's committee under reference number CPP2019-12-098. The study has been registered under the reference number NCT04434586 on the Web site of clinicaltrials.gov., Results: The primary outcome of the study is the primary patency at 12 months. The number of patients who need to be treated is 166 (83 in each group) considering 5% of no workable data. Symptoms' improvement, target lesion revascularization, target vessel revascularization, quality-of-life questionnaires, cost utility, and cost effectiveness will be analyzed as secondary end-point variables at 12 months., Conclusions: The present study is to evaluate the potential benefit for patients on the result of endovascular revascularization of long occlusive femoropopliteal lesion at 12 months when using intraoperative OCT control., (Copyright © 2020 Elsevier Inc.

- Abstract
Objective: The aim of this study was to compare the efficacy and safety of 12-month implantation of a duodeno-jejunal bypass liner (DJBL) with conventional medical care in patients with metabolic syndrome (MS)., Summary Background Data: DJBL is an endoscopic device for treating obesity and related disorders. The persistence of favorable results after 6 months has not been tested in a controlled study., Methods: We conducted a multicenter randomized controlled trial, stratified by center and diabetes status. The primary endpoint was the remission of MS at 12 months. The secondary endpoints included body mass index (BMI), glucose control, blood pressure, and lipids, assessed at 12 months after implantation, and again, at 12 months after the removal of the DJBL. Up to 174 subjects were planned to be randomized into either the DJBL or the control arm at a 2:1 ratio, respectively. Study enrollment was discontinued by the Scientific Monitoring Committee due to the early termination of the ENDO trial (NCT01728116) by the US Food and Drug Administration. The study was terminated after withdrawal of the device's European Conformity marking by the European Medicines Agency, and an interim analysis was performed., Results: A total of 82 patients were enrolled (67.5% female, 48.8% with diabetes). At 12 months after randomization, the primary endpoint was met in 6 (12%) DJBL patients and 3 (10%) controls (P = 0.72). Patients in the DJBL group experienced greater BMI loss [mean adjusted difference (95% confidence interval, CI) -3.1 kg/m (-4.4 to -1.9) kg/m, P < 0.001] and HbA1c change [mean adjusted difference -0.5% (95% CI -0.9 to -0.2); P < 0.001] than those in the control group. No difference remained statistically significant at 12 months after the removal of the DJBL. In the DJBL group, 39% of patients experienced at least one device-related serious adverse event, which was classified as Grade III Dindo-Clavien in 22%, and required premature device explantation in 16%., Conclusions: The present study showed a transient clinical benefit of DJBL, which was only apparent at 1 year, when the device was still in situ, and was obtained at the risk of serious device-related adverse events in 39% of patients. These results do not support the routine use of DJBL for weight loss and glucose control in patients with MS.

- Abstract
Background: Usability testing of medical devices are mandatory for market access. The testings' goal is to identify usability problems that could cause harm to the user or limit the device's effectiveness. In practice, human factor engineers study participants under actual conditions of use and list the problems encountered. This results in a binary discovery matrix in which each row corresponds to a participant, and each column corresponds to a usability problem. One of the main challenges in usability testing is estimating the total number of problems, in order to assess the completeness of the discovery process. Today's margin-based methods fit the column sums to a binomial model of problem detection. However, the discovery matrix actually observed is truncated because of undiscovered problems, which corresponds to fitting the marginal sums without the zeros. Margin-based methods fail to overcome the bias related to truncation of the matrix. The objective of the present study was to develop and test a matrix-based method for estimating the total number of usability problems., Methods: The matrix-based model was based on the full discovery matrix (including unobserved columns) and not solely on a summary of the data (e.g. the margins). This model also circumvents a drawback of margin-based methods by simultaneously estimating the model's parameters and the total number of problems. Furthermore, the matrix-based method takes account of a heterogeneous probability of detection, which reflects a real-life setting. As suggested in the usability literature, we assumed that the probability of detection had a logit-normal distribution., Results: We assessed the matrix-based method's performance in a range of settings reflecting real-life usability testing and with heterogeneous probabilities of problem detection. In our simulations, the matrix-based method improved the estimation of the number of problems (in terms of bias, consistency, and coverage probability) in a wide range of settings. We also applied our method to five real datasets from usability testing., Conclusions: Estimation models (and particularly matrix-based models) are of value in estimating and monitoring the detection process during usability testing. Matrix-based models have a solid mathematical grounding and, with a view to facilitating the decision-making process for both regulators and device manufacturers, should be incorporated into current standards.

- Abstract
Background: Postoperative upper gastrointestinal fistula (PUGIF) is a devastating complication, leading to high mortality (reaching up to 80%), increased length of hospital stay, reduced health-related quality of life and increased health costs. Nutritional support is a key component of therapy in such cases, which is related to the high prevalence of malnutrition. In the prophylactic setting, enteral nutrition (EN) is associated with a shorter hospital stay, a lower incidence of severe infectious complications, lower severity of complications and decreased cost compared to total parenteral nutrition (TPN) following major upper gastrointestinal (GI) surgery. There is little evidence available for the curative setting after fistula occurrence. We hypothesize that EN increases the 30-day fistula closure rate in PUGIF, allowing better health-related quality of life without increasing the morbidity or mortality., Methods/design: The NUTRILEAK trial is a multicenter, randomized, parallel-group, open-label phase III trial to assess the efficacy of EN (the experimental group) compared with TPN (the control group) in patients with PUGIF. The primary objective of the study is to compare EN versus TPN in the treatment of PUGIF (after esophagogastric resection including bariatric surgery, duodenojejunal resection or pancreatic resection with digestive tract violation) in terms of the 30-day fistula closure rate. Secondary objectives are to evaluate the 6-month postrandomization fistula closure rate, time of first fistula closure (in days), the medical- and surgical treatment-related complication rate at 6 months after randomization, the fistula-related complication rate at 6 months after randomization, the type and severity of early (30 days after randomization) and late fistula-related complications (over 30 days after randomization), 30-day and 6-month postrandomization mortality rate, nutritional status at day 30, day 60, day 90 and day 180 postrandomization, the mean length of hospital stay, the patient's health-related quality of life (by self-assessment questionnaire), oral feeding time and direct costs of treatment. A total of 321 patients will be enrolled., Discussion: The two nutritional supports are already used in daily practice, but most surgeons are reluctant to use the enteral route in case of PUGIF. This study will be the first randomized trial testing the role of EN versus TPN in PUGIF., Trial Registration: ClinicalTrials.gov: NCT03742752. Registered on 14 November 2018.

- Abstract
Background: Catheter-related bacteremia (CRB) is the most frequent nosocomial infection in neonatal intensive care unit (NICU) patients, especially in very low-birth-weight infants. Administration of injectable drugs in premature newborn infants has many particularities and several types of infusion incidents have been reported. The Edelvaiss® Multiline NEO device is a novel multi-lumen access infusion device adapted to the specificities of infusion in neonatology. This multicenter, randomized, controlled study was therefore designed to determine whether or not Edelvaiss® Multiline NEO reduces the risk of CRB in preterm newborn infants in an NICU., Methods/design: This is a multicenter, randomized, controlled trial, using a cluster-randomized crossover design. Four investigator centers (four clusters) will participate in the study and will be randomized into two groups, corresponding to two different sequences (either the Edelvaiss® Multiline NEO or standard infusion system sequence, then vice versa). A total of 280 patients will be recruited. Infants will be enrolled in the study at the time of placing a single-lumen central venous catheter. Three visits recording specific data are planned in the study protocol. The primary outcome measure is the incidence density (ID) of CRB. For each patient, the total number of catheters and CRB incidents as well as the duration of stay in the NICU will be computed and considered for analysis., Discussion: The study will provide high-quality evidence to determine whether the Multiline NEO device reduces the risk of CRB in preterm newborns in NICUs or not., Trial Registration: ClinicalTrials.gov, NCT02633124 .

- Abstract
Background and Aims: The potential benefit of the centralization of Bariatric surgery (BS) remains debated. The aim of this study was to evaluate the impact on 90-day mortality of an innovative organization aiming at centralizing the care of severe postoperative complications of BS., Study Design: The centralization of care for postoperative complication after BS was implemented by French Authorities in 2013 in the Nord-Pas-de-Calais Region, France. This unique formalized network (OSEAN), coordinated by 1 tertiary referral center, enrolled all regional institutions performing bariatric surgery. Data were extracted from the medico-administrative database providing information on all patients undergoing BS between 2009 and 2016 in OSEAN (n = 22,928) and in Rest of France (n = 288,942). The primary outcome was the evolution of 90-day mortality before and after the implementation of this policy. Rest of France was used as a control group to adjust the results to improvement with time of BS outcomes., Results: The numbers of primary procedure and reoperations increased similarly before and after 2013 within OSEAN and in Rest of France. The 90-day mortality rate became significantly lower within OSEAN than in the rest of France after 2013 (0.03% vs 0.08%, P < 0.01). This difference was confirmed in multivariate analysis after adjustment to the procedure specific mortality (P < 0.04). The reduction of 90-day mortality was most visible for sleeve gastrectomy., Conclusion: The implementation of centralized care for early postoperative complications after BS in OSEAN was associated with reduced 90-day mortality. Our results indicate that this reduction was not due to a lower incidence of complications but to the improvement of their management.

- Abstract
BackgroundLarge measles and mumps outbreaks recently occurred throughout Europe and the United States. Aim : Our aim was to estimate and map the risk of resurgence for measles, mumps and rubella in France. Methods : We used a multi-cohort model combining seroprevalence information, vaccine coverage and social contact data. Results : The overall outbreak risk for France in 2018 was highest for mumps, remained significant for measles despite a recent measles outbreak and was low for rubella. Outbreak risks were heterogeneous between departments, as the effective reproduction numbers for 2018 ranged from 1.08 to 3.66. The seroprevalence, and therefore the risk of measles and rubella infection, differed significantly between males and females. There was a lower seroprevalence, and therefore a higher risk, for males. Infants of less than 1 year would be seriously affected in a future outbreak of measles, mumps or rubella, but the highest overall caseload contribution would come from teenagers and young adults (10-25 years old). Conclusions : The high risk for teenagers and young adults is of concern in view of their vulnerability to more severe measles, mumps and rubella disease and complications.

- Abstract
Early market access of health products is associated with a larger number of requests for information by the health authorities. Compared with these expectations, the growing expansion of health databases represents an opportunity for responding to questions raised by the authorities. The computerised nature of the health system provides numerous sources of data, and first and foremost medical/administrative databases such as the French National Inter-Scheme Health Insurance Information System (SNIIRAM) database. These databases, although developed for other purposes, have already been used for many years with regard to post-registration studies (PRS). The use thereof will continue to increase with the recent creation of the French National Health Data System (SNDS [2016 health system reform law]). At the same time, other databases are available in France, offering an illustration of "product use under actual practice conditions" by patients and health professionals (cohorts, specific registries, data warehouses, etc.). Based on a preliminary analysis of requests for PRS, approximately two-thirds appeared to have found at least a partial response in existing databases. Using these databases has a number of disadvantages, but also numerous advantages, which are listed. In order to facilitate access and optimise their use, it seemed important to draw up recommendations aiming to facilitate these developments and guarantee the conditions for their technical validity. The recommendations drawn up notably include the need for measures aiming to promote the visibility of research conducted on databases in the field of PRS. Moreover, it seemed worthwhile to promote the interoperability of health data warehouses, to make it possible to match information originating from field studies with information originating from databases, and to develop and share algorithms aiming to identify criteria of interest (proxies). Methodological documents, such as the French National Authority for Health (HAS) recommendations on "Les études post-inscription sur les technologies de santé (médicaments, dispositifs médicaux et actes). Principes et méthodes" [Post-registration studies on health technologies (medicinal products, medical devices and procedures). Principles and methods] should be updated to incorporate these developments., (Copyright © 2018 Société française de pharmacologie et de thérapeutique. Published by Elsevier Masson SAS.

- Abstract
Purpose: The aim of this study was to determine the impact of a biomarker-based strategy on early discontinuation of empirical antifungal treatment., Methods: Prospective randomized controlled single-center unblinded study, performed in a mixed ICU. A total of 110 patients were randomly assigned to a strategy in which empirical antifungal treatment duration was determined by (1,3)-β-D-glucan, mannan, and anti-mannan serum assays, performed on day 0 and day 4; or to a routine care strategy, based on international guidelines, which recommend 14 days of treatment. In the biomarker group, early stop recommendation was determined using an algorithm based on the results of biomarkers. The primary outcome was the percentage of survivors discontinuing empirical antifungal treatment early, defined as a discontinuation strictly before day 7., Results: A total of 109 patients were analyzed (one patient withdraw consent). Empirical antifungal treatment was discontinued early in 29 out of 54 patients in the biomarker strategy group, compared with one patient out of 55 in the routine strategy group [54% vs 2%, p < 0.001, OR (95% CI) 62.6 (8.1-486)]. Total duration of antifungal treatment was significantly shorter in the biomarker strategy compared with routine strategy [median (IQR) 6 (4-13) vs 13 (12-14) days, p < 0.0001). No significant difference was found in the percentage of patients with subsequent proven invasive Candida infection, mechanical ventilation-free days, length of ICU stay, cost, and ICU mortality between the two study groups., Conclusions: The use of a biomarker-based strategy increased the percentage of early discontinuation of empirical antifungal treatment among critically ill patients with suspected invasive Candida infection. These results confirm previous findings suggesting that early discontinuation of empirical antifungal treatment had no negative impact on outcome. However, further studies are needed to confirm the safety of this strategy. This trial was registered at ClinicalTrials.gov, NCT02154178.
