Mechanical Thrombectomy with Intravenous Thrombolysis versus Thrombolysis Alone for the Treatment of Stroke: A Systematic Review of Economic Evaluations.

Mechanical thrombectomy has revolutionized the management of stroke by improving the recanalization rates and reducing deleterious consequences. It is now the standard of care despite the high financial cost. A considerable number of studies have evaluated its cost effectiveness. Therefore, this study aimed to identify economic evaluations of mechanical thrombectomy with thrombolysis compared with thrombolysis alone to provide an update of existing evidence, focusing on the period after proof of effectiveness of mechanical thrombectomy. Twenty-one studies were included in the review: 18 were model-based economic evaluations to simulate long-term outcomes and costs, and 19 were conducted in high-income countries. Incremental cost-effectiveness ratios ranged from -$5,670 to $74,216 per quality-adjusted life year. Mechanical thrombectomy is cost-effective in high-income countries and in the populations selected for clinical trials. However, most of the studies used the same data. There is a lack of real-world and long-term data to analyze the cost effectiveness of mechanical thrombectomy in treating the global burden of stroke.

Economic impact of generic antiretrovirals in France for HIV patients' care: a simulation between 2019 and 2023.

BACKGROUND: In a context where the economic burden of HIV is increasing as HIV patients now have a close to normal lifespan, the availability of generic antiretrovirals commonly prescribed in 2017 and the imminence of patent expiration are expected to provide substantial savings in the coming years. This article aims to assess the economic impact of these generic antiretrovirals in France and specifically over a five-year period. METHODS: An agent-based model was developed to simulate patient trajectories and treatment use over a five-year period. By comparing the results of costs for trajectories simulated under different predefined scenarios, a budget impact model can be created and sensitivity analyses performed on several parameters of importance. RESULTS: The potential economic savings from 2019 to 2023 generated by generic antiretrovirals range from €309 million when the penetration rate of generics is set at 10% to €1.5 billion at 70%. These savings range from €984 million to €993 million as the delay between patent and generic marketing authorisation varies from 10 to 15 years, and from €965 million to €993 million as the Negotiated Price per Unit (NPU) of generics at market-entry varies from 40 to 50% of the NPU for patents. DISCUSSION: This economic savings simulation could help decision makers to anticipate resource allocations for further innovation in antiretrovirals therapies as well as prevention, especially by funding the Pre-Exposure Prophylaxis (PrEP) or HIV screening.

The healthcare costs of antimicrobial resistance in Lebanon: a multi-centre prospective cohort study from the payer perspective.

BACKGROUND: Our aim was to examine whether the length of stay, hospital charges and in-hospital mortality attributable to healthcare- and community-associated infections due to antimicrobial-resistant bacteria were higher compared with those due to susceptible bacteria in the Lebanese healthcare settings using different methodology of analysis from the payer perspective . METHODS: We performed a multi-centre prospective cohort study in ten hospitals across Lebanon. The sample size consisted of 1289 patients with documented healthcare-associated infection (HAI) or community-associated infection (CAI). We conducted three separate analysis to adjust for confounders and time-dependent bias: (1) Post-HAIs in which we included the excess LOS and hospital charges incurred after infection and (2) Matched cohort, in which we matched the patients based on propensity score estimates (3) The conventional method, in which we considered the entire hospital stay and allocated charges attributable to CAI. The linear regression models accounted for multiple confounders. RESULTS: HAIs and CAIs with resistant versus susceptible bacteria were associated with a significant excess length of hospital stay (2.69 days [95% CI,1.5-3.9]; p < 0.001) and (2.2 days [95% CI,1.2-3.3]; p < 0.001) and resulted in additional hospital charges ($1807 [95% CI, 1046-2569]; p < 0.001) and ($889 [95% CI, 378-1400]; p = 0.001) respectively. Compared with the post-HAIs analysis, the matched cohort method showed a reduction by 26 and 13% in hospital charges and LOS estimates respectively. Infections with resistant bacteria did not decrease the time to in-hospital mortality, for both healthcare- or community-associated infections. Resistant cases in the post-HAIs analysis showed a significantly higher risk of in-hospital mortality (odds ratio, 0.517 [95% CI, 0.327-0.820]; p = 0.05). CONCLUSION: This is the first nationwide study that quantifies the healthcare costs of antimicrobial resistance in Lebanon. For cases with HAIs, matched cohort analysis showed more conservative estimates compared with post-HAIs method. The differences in estimates highlight the need for a unified methodology to estimate the burden of antimicrobial resistance in order to accurately advise health policy makers and prioritize resources expenditure.

Health-related quality of life during pregnancy: A repeated measures study of changes from the first trimester to birth.

INTRODUCTION: The objective was to evaluate the quality of life of pregnant women with a full-term birth from the first trimester to the 9th month using the EQ5D-3L questionnaire, comparing physiological, simple pathological, or complex pathological pregnancies. MATERIAL AND METHODS: A prospective cohort of 500 pregnant women over the age of 18 was monitored between 2015 and 2017 at the Toulouse University Hospital (France). The data were collected monthly with an online report. Given that the decrease in quality of life was not linear during pregnancy, unadjusted and adjusted piecewise linear regression models were performed, considering 3 periods of time during pregnancy: 3-4, 4-8, and 8-9 months. The 5 dimensions of the EQ5D-Index and perceived health status were also analyzed. RESULTS: In total, 1847 questionnaires were collected. Between the 4th and 8th months, the quality of life was lower for pathological pregnancies (P < 0.001) than for physiological ones and decreased over time for each type of pregnancy (physiological: -0.08 points per month, P < 0.001; simple pathological: -0.12 points per month, P < 0.001; complex pathological: -0.11 points per month, P < 0.001). Interestingly, the perceived health status was lower at the 9th month than at the 3rd month of pregnancy, for physiological pregnancies (mean difference = -10.5 points, P < 0.001), pathological pregnancies (mean difference = -10.0 points, P < 0.002), and for complex pathological pregnancies (mean difference = -7.8 points, P = 0.058). CONCLUSIONS: In our population, the quality of life decreased between the 4th and 8th months, and decreased to a greater degree in a pathological pregnancy.

Cochlear implantation as a treatment for single-sided deafness and asymmetric hearing loss: a randomized controlled evaluation of cost-utility.

BACKGROUND: Single-sided deafness (SSD) and asymmetric hearing loss (AHL) have recently been proposed as a new indication for cochlear implantation. There is still no recommended treatment for these hearing deficits, and most options considered rely on the transfer of sound from the poor ear to the better ear, using Contralateral Routing of the Signal (CROS) hearing aids or bone conduction (BC) devices. In contrast, cochlear implantation allows the poor ear to be stimulated and binaural hearing abilities to be partially restored. Indeed, most recently published studies have reported an improvement in the spatial localisation of an incoming sound and better speech recognition in noisy environments after cochlear implantation in SSD/AHL subjects. It also provides consistent relief of tinnitus when associated. These encouraging hearing outcomes raise the question of the cost-utility of this expensive treatment in an extended indication. METHODS: The final endpoint of this national multicentre study is to determine the incremental cost-utility ratio (ICUR) of cochlear implantation in comparison to the current standard of care in France through simple observation, using a randomised controlled trial. Firstly, the study comprises a prospective and descriptive part, where 150 SSD/AHL subjects try CROS hearing aids and a BC device for three weeks each. Secondly, the choice is made between CROS hearing aids, BC implanted device and cochlear implantation. Hearing outcomes and quality of life measurements are described after 6 months for the subjects who chose CROS, BC or declined any option. The subjects who opt for cochlear implantation are randomised between one group where the cochlear implant is inserted without delay and one group of simple initial observation. Hearing outcomes and quality of life measurements are compared after 6 months. DISCUSSION: The present study was designed to assess the efficiency of cochlear implantation in SSD/AHL. A favourable cost-utility ratio in this extended indication would strengthen the promising clinical results and justify a reimbursement by the health insurance. The efficiency of other options (CROS, BC) will also be described. TRIAL REGISTRATION: This research has been registered in ClinicalTrials.gov (http://www.clinicaltrials.gov/), the 29th July 2014 under the n°NCT02204618.

Cost-effectiveness of trans-nasal endoscopic sphenopalatine artery ligation vs arterial embolisation for intractable epistaxis: Long-term analyses.

OBJECTIVES: Trans-nasal endoscopic sphenopalatine artery ligation (TESPAL) and endovascular arterial embolisation both provide excellent success rates for intractable epistaxis. Recent economic models suggest that TESPAL could be a cost-saving strategy. Our main aim was to perform cost-effectiveness analyses on TESPAL compared with embolisation to treat patients with epistaxis. DESIGN: We performed retrospective, monocentric, comparative analyses on patients referred to our centre and treated with embolisation or TESPAL. SETTING: This economic evaluation was carried out from a payer's perspective (ie French National Health Insurance) within a time horizon of 12 months. PARTICIPANTS: Thirty-seven TESPAL procedures and thirty-nine embolisation procedures to treat intractable epistaxis were used in the analyses. MAIN OUTCOME MEASURES: The primary outcome is presented as the cost per 1% of non-recurrence. Effectiveness was defined as avoiding recurrence of epistaxis during the 1-year follow-up. Cost estimates were performed from the payer's perspective. RESULTS: Hospitalisation costs were higher for embolisation compared with TESPAL (5972 vs 3769 euros). On average, hospitalisation costs decreased by 41% when a patient was treated by TESPAL compared with an embolisation strategy (P = 0.06). The presence of comorbidities increased hospitalisation costs by 79% (P = 0.04). TESPAL enabled 1867€ to be gained in intractable epistaxis. CONCLUSIONS: The outcomes from our decision model confirm that TESPAL is more cost-effective for patients with intractable epistaxis.

Concerns About Lung Cancer Among Prisoners.

BACKGROUND: Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients. METHOD: We performed a multi-center observational case-control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case-control ratio: 1:3). Incidence rates in both groups were calculated using national statistics. RESULTS: Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls (p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008-2012) in male prisoners were higher than those in the general population in all concerned age groups. CONCLUSION: There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.

Cost Effectiveness of Candida Polymerase Chain Reaction Detection and Empirical Antifungal Treatment among Patients with Suspected Fungal Peritonitis in the Intensive Care Unit.

BACKGROUND: Mortality from intra-abdominal candidiasis in intensive care units (ICUs) is high. It takes many days for peritoneal-fluid fungal culture to become positive, and the recommended empirical antifungal therapy involves excessive costs. Polymerase chain reaction (PCR) should produce results more rapidly than fungal culture. OBJECTIVES: To perform a cost-effectiveness analysis of the combination of several diagnostic and therapeutic strategies to manage Candida peritonitis in non-neutropenic adult patients in ICUs. METHODS: We constructed a decision tree model to evaluate the cost effectiveness. Cost and effectiveness were taken into account in a 1-year time horizon and from the French National Health Insurance perspective. Six strategies were compared: fluconazole or echinocandin as an empirical therapy, plus diagnosis by fungal culture or detection by PCR of all Candida species, or use of PCR to detect most fluconazole-resistant Candida species (i.e., Candida krusei and Candida glabrata). RESULTS: The use of fluconazole empirical treatment and PCR to detect all Candida species is more cost effective than using fluconazole empirical treatment without PCR (incremental cost-effectiveness ratio of €40,055/quality-adjusted life-year). Empirical treatment with echinocandin plus PCR to detect C. krusei and C. glabrata is the most effective strategy, but has an incremental cost-effectiveness ratio of €93,776/quality-adjusted life-year. If the cost of echinocandin decreases, then strategies involving PCR plus empirical echinocandin become more cost-effective. CONCLUSIONS: Detection by PCR of all Candida species and of most fluconazole-resistant Candida species could improve the cost-effectiveness of fluconazole and echinocandin given to non-neutropenic patients with suspected peritoneal candidiasis in ICUs.

Observational Studies Requested by European Health Authorities: Governmental Interference or an Enhancement of Everyday Urological Practice? The Hexvix® Observational Patients Evaluation Study as an Example of What to Expect.

OBJECTIVE: The Hexvix® Observational Patients Evaluation (HOPE) study was designed to determine the extent of distribution of the use of hexaminolevulinate in the diagnosis of non-muscle invasive bladder cancer (NMIBC) and assess patient and treatment characteristics associated with different endoscopic modalities and to address the French authorities' request for information on routine practices for NMIBC diagnosis and surveillance. PATIENTS AND METHODS: A prospective, observational study in 30 centres in France with fluorescence endoscopy equipment available. All candidates for endoscopy with transurethral resection who gave their consent were eligible. The primary endpoint was the proportion of patients with an NMIBC diagnosis performed with hexaminolevulinate. RESULTS: 506 patients were included: 252 (49.8%) diagnosed with hexaminolevulinate and 254 (50.2%) with white-light endoscopy alone. There were more patients with tumour recurrence, multiple lesions, lesions with a diameter <3 cm, stage Ta disease, and grade 1 lesions in the hexaminolevulinate group. The first quartile median recurrence-free survival time was 310 days in the hexaminolevulinate group and 144 days in the standard-endoscopy group (p = 0.0015). CONCLUSION: Hexaminolevulinate was in frequent use in France with specific patient and disease characteristics associated with its use. HOPE illustrates the type of data that can be gained in post-authorisation studies to address requests from European health authorities.

Study protocol of the CREDO randomised controlled trial: evaluation of a structured return home consultation for patients suffering from metastaticcancer.

INTRODUCTION: Patients suffering from cancer are often managed by multiple health professionals. General practitioners with specific skills in oncology could facilitate care coordination between hospital and general practice in the management of these patients. To explore this hypothesis, we run a randomised clinical trial, called 'Concertation de REtour à DOmicile, CREDO'. The main objective is to explore the effectiveness of a 'return home' consultation compared with standard care. The number of unscheduled visits to care centres is used to evaluate the effectiveness of the treatment. METHODS AND ANALYSIS: CREDO is a multicentre, randomised, open-label, prospective trial. It takes place in two specialised cancer care centres in southern France (Occitania region). Patient inclusion criteria are: be over 18 years old; be treated with a first cycle of metastatic chemotherapy in a specialised cancer care centre; have a metastatic solid cancer and be returning home after treatment. Patients are randomised in two arms: standard-arm (conventional management) or intervention-arm (CREDO management). In the intervention arm, a 'return home' consultation is carried out in three steps. First, the investigating GP (GP with specific skills in oncology) from the specialised care centre collects information about the patient and patient's management choices. Then, the investigating GP conducts an interview with the patient's referring GP to quickly communicate and discuss information about the patient. Finally, the investigating GP summarises these exchanges and transmits this information to the care centres chosen by the patient.All the patients are followed for 1 year.Statistical and medicoeconomic analysis are planned. ETHICS AND DISSEMINATION: This clinical trial is registered under ClinicalTrials.gov identifier and was approved by the ethics committee of South-Western French Committee for the Protection of Persons (number: 2016-A01587-44) and from the French National Drug Safety Agency (ANSM, number: 2016111500034).An international publication of the final results and conference presentations will be planned. TRIAL REGISTRATION NUMBER: NCT02857400.

Influence of deprivation on hospital care pathways and costs for people with ischaemic stroke: A trajectory modelling study.

BACKGROUND: Socioeconomic characteristics have a strong impact on the incidence of stroke. The highest levels of morbidity and mortality are associated with the lowest socioeconomic positions. Moreover, the health insurance budget for stroke is significant. OBJECTIVES: To describe typical Hospital Care Pathways (HCPs) and their costs 1 year after acute stroke and to assess the impact of individuals' socioeconomic characteristics on HCPs and costs. METHODS: This retrospective observational study used hospital data on people with primary ischaemic stroke in a region of France (Haute-Garonne). HCPs were identified by sequential analysis. Multinomial logistic regression was used to analyse the impact of socioeconomic characteristics on HCPs as measured using an ecological index of deprivation, and a gamma regression model was used to analyse costs. RESULTS: The analysis identified 4 typical HCPs. The first HCP consisted exclusively of consultations, the second was composed of consultations and hospitalisations, the third included hospitalisations during the first 2 months after stroke followed by consultations, and the fourth included long-term hospitalisations. After adjustment, deprivation was associated with HCPs and determined its costs: a high level of social disadvantage determined the type of pathway and increased the costs. CONCLUSIONS: This study is one of the first to assess the impact of social inequalities in health on post-stroke HCPs in France and their corresponding costs. Our results confirm the hypothesis that healthcare costs differ according to the level of deprivation.

Cost Analysis of Radiofrequency Ablation for Adrenal Adenoma in Patients with Primary Aldosteronism and Hypertension: Results from the ADERADHTA Pilot Study and Comparison with Surgical Adrenalectomy.

PURPOSE: Primary Aldosteronism (PA) is increasingly considered as a common disease affecting up to 10% of the hypertensive population. Standard of care comprises laparoscopic total adrenalectomy but innovative treatment such as RadioFrequency Ablation (RFA) constitutes an emerging promising alternative to surgery. The main aim of this study is to analyse the cost of RFA versus surgery on aldosterone-producing adenoma patient from the French National Health Insurance (FNHI) perspective. METHODS: The ADERADHTA study was a prospective pilot study aiming to evaluate both safety and efficacy of the novel use of adrenal RFA on the patients with PA. This study conducted on two French sites and enrolled adult patients, between 2016 and 2018, presenting hypertension and underwent the RFA procedure. Direct medical (inpatient and outpatient) and non-medical (transportation, daily allowance) costs were calculated over a 6-month follow-up period. Moreover, the procedure costs for the RFA were calculated from the hospital perspective. Descriptive statistics were implemented. RESULTS: Analysis was done on 21 patients in RFA groups and 27 patients in the surgery group. The difference in hospital costs between the RFA and surgery groups was €3774 (RFA: €1923; Surgery: €5697 p < 0.001) in favour of RFA. Inpatient and outpatient costs over the 6-month follow-up period were estimated at €3,48 for patients who underwent RFA. The production cost of implementing the RFA procedure was estimated at €1539 from the hospital perspective. CONCLUSION: Our study was the first to show that RFA is 2 to 3 times less costly than surgery. The trial is registered at ClinicalTrials.gov under the number NCT02756754.

Costs and Survival of Patients having Experienced a Hospitalized Fall-Related Injury in France: A Population-Based Study.

OBJECTIVES: To assess the annual costs 2 years before and 2 years after a hospitalized fall-related injury (HFRI) and the 2-year survival among the population 75+ years old. DESIGN: We performed a population-based, retrospective cohort study using the French national health insurance claims database. SETTING AND PARTICIPANTS: Patients 75+ years old who had experienced a fall followed by hospitalization, identified using an algorithm based on International Classification of Diseases codes. Data related to a non-HFRI population matched on the basis of age, sex, and geographical area were also extracted. METHODS: Cost analyses were performed from a health insurance perspective and included direct costs. Survival analyses were conducted using Kaplan-Meier curves and Cox regression. Descriptive analyses of costs and regression modeling were carried out. Both regression models for costs and on survival were adjusted for age, sex, and comorbidities. RESULTS: A total of 1495 patients with HFRI and 4484 non-HFRI patients were identified. Patients with HFRI were more comorbid than the non-HFRI patients over the entire periods, particularly in the year before and the year after the HFRI. Patients with HFRI have significantly worse survival probabilities, with an adjusted 2.14-times greater risk of death over 2-year follow-up and heterogeneous effects determined by sex. The annual incremental costs between patients with HFRI and non-HFRI individuals were €1294 and €2378, respectively, 2 and 1 year before the HFRI, and €11,796 and €1659, respectively, 1 and 2 years after the HFRI. The main cost components differ according to the periods and are mainly accounted for by paramedical acts, hospitalizations, and drug costs. When fully adjusted, the year before the HFRI and the year after the HFRI are associated with increase in costs. CONCLUSIONS AND IMPLICATIONS: We have provided real-world estimates of the cost and the survival associated with patients with HFRI. Our results highlight the urgent need to manage patients with HFRI at an early stage to reduce the significant mortality as well as substantial additional cost management. Special attention must be paid to the fall-related increasing drugs and to optimizing management of comorbidities.

Primary prevention of nephrolithiasis is cost-effective for a national healthcare system.

UNLABELLED: Study Type--Therapy (cost-effectiveness meeting) Level of Evidence 2b. What's known on the subject? and What does the study add? One of the major problems with nephrolithiasis is the high rate of recurrence, which can effect up to 50% of patients over a 5-year period. Patients with recurrent stones are recommended to increase fluid intake based on prospective studies that show a reduction in recurrence rates in patients who intake a high volume of water. Strategies to reduce stones in recurrent stone formers are quite effective with a >50% risk reduction with increased fluid intake alone. Unfortunately, despite a high societal cost and morbidity, there are no prospective studies evaluating the benefit of fluid intake to prevent stone disease in subjects without a prior history of stone but at risk for stones. The budget impact analyses show that prevention of nephrolithiasis can have a significant cost savings for a payer in a healthcare system and reduce the stone burden significantly. Future studies will need to assess the feasibility and effectiveness of such an approach in a population. OBJECTIVE: • To evaluate the impact of primary prevention of stones using a strategy of increased fluid intake. SUBJECTS AND METHODS: • A Markov model was constructed and analysed using Excel to calculate and compare the costs and outcomes for a virtual cohort of subjects with low vs high water intake. • A literature search was used to formulate assumptions for the model including an annual incidence of urolithiasis of 0.032%, annual risk of stone recurrence of 14.4% and 40% risk reduction in subjects with high water intake. • Costs were based on resource utilisation from the Delphi panel and official price lists in France. • Outcomes were based on payer perspective and included direct and indirect costs and loss of work. RESULTS: • The base-case analysis found total cost of urolithiasis is €4267 with direct costs of €2767, including cost of treatment and complications. The annual budget impact for stone disease based on 65 million inhabitants is €590 million for the payer. • The use of high water intake by 100% of the population results in annual cost savings of €273 million and 9265 fewer stones. Even if only 25% of the population is compliant, there is still a cost saving of €68 million and 2316 stones. • The model was evaluated to determine the impact of varying the assumptions by ±10%. For example, when the incidence of stone disease is increased or decreased by 10% then the mean (range) baseline cost will change by €59(531-649) million for the payer and savings will either increase or decrease by €27 (246-300) million. • The largest impact on cost savings occurs when varying risk reduction of water by 10% resulting in either a mean (range) increase or decrease by €35 (238-308) million. • Varying cost of stone management by 10% has an impact of ±€17 million. Varying other factors such as stone recurrence by 10% has only an impact of ±€9 million and varying risk of chronic kidney disease ±€1 million, as they affect only a portion of the population. CONCLUSIONS: • The budget impact analyses show that prevention of nephrolithiasis can have a significant cost savings for a payer in a healthcare system and reduce the stone burden significantly. • Future studies will need to assess the feasibility and effectiveness of such an approach in a population.

Exploring the relationship between Alzheimer's disease severity and longitudinal costs.

OBJECTIVE: The joint impact of cognitive, functional, and behavioral statuses must be measured when exploring the impact of new drugs on Alzheimer's disease (AD) costs. There are very few recent studies of AD costs by all dimensions of disease severity. Our objective was to improve estimation of the relationship between AD severity and costs of AD care by using more comprehensive AD data severity and a large sample size. METHODS: Participants were community-dwelling AD patients recruited between 2003 and 2005 and followed annually during a 2-year period in 50 French memory clinics. We used the Resource Use in Dementia questionnaire to estimate costs from a societal perspective. We explored the presence of potential endogeneity bias by using instrumental variable regressions. RESULTS: Cognitive declines impacted informal costs more than medical and nonmedical costs, while functional declines impacted nonmedical costs more than medical and informal costs. Both cognitive and function declines increased the total costs of care. We found that the endogeneity of these variables led to a large underestimation of their impact of AD severity on costs. CONCLUSION: Potential endogeneity should be controlled for to prevent biased estimations of the impact of AD severity measures on costs.

Use of multiple sources and capture-recapture method to estimate the frequency of hospitalizations related to drug abuse.

PURPOSE: Addictive behaviours are often associated with hidden characteristics that are difficult to detect by usual approaches. This study aimed to estimate the incidence of serious drug-related complications by using the capture-recapture method in defined geographical area. METHODS: Hospitalizations with mention of disorders related to drug of abuse were considered serious drug-related complications. We searched these cases in and crossed three sources of data: spontaneous reports of drug of abuse-related disorders called NotS ('Notification Spontanee') collected by the regional addictovigilance centre, computerised hospital database Programme de Medicalisation des Systemes d'Information (PMSI) and toxicological analyses (TA) carried out for hospitalized patients. RESULTS: In 2007 and 2008, 1509 distinct cases were captured. After data modelling, the estimated number of psychoactive drug-related hospitalizations was 4744 (95%CI = 4060-5429). Most frequent products were opioids (34%), cannabis (19%) and cocaine (13%). 'Multiple drugs' were observed in 26% of cases. The incidence of serious drug-related complications in the area covered should be estimated at 5.7 (95%CI = 5.5-5.9) per thousand 15- to 64-year-old inhabitants. The exhaustiveness of sources were 0.4% (95%CI = 0.2-0.6) for NotS, 11.6% (95%CI = 10.7-12.5) for TA and 22.6% (95%CI = 21.4-23.8) for PMSI. CONCLUSIONS: The 'real' number of cases far exceeds that of cases that can be identified through simple counts. In particular, it confirms the underreporting and even quantifies its magnitude. These results confirm that drug users are frequently hospitalised and require heavy medical management. Moreover, these results show the real although limited advantage of hospitalization database in detecting drug associated disorders in epidemiological studies.

Reduction prevalence of fragility fracture hospitalisation during the COVID-19 lockdown.

Fracture hospitalizations of people ≥ 65 years old living in France increased annually from 2015 until 2019 (average: 1.8%), until being reduced in 2020 (- 1.4%) with an abrupt decrease during the lockdown period. Decreased exposure to the risk of falling during COVID-19 year 2020 may have reflected in lower incidence of fractures.

Cost-effectiveness analysis of vaginal misoprostol versus dinoprostone pessary: A non-inferiority large randomized controlled trial in France.

OBJECTIVE: To assess the cost-effectiveness of vaginal misoprostol (PGE1; 25 µg) compared with a slow-release dinoprostone (PGE2) pessary (10 µg) for labor induction due to an unfavorable cervix at term. METHODS: We used data from an open-label multicenter, randomized non-inferiority trial that recruited women for whom labor was induced for medical reasons. The incremental cost-effectiveness ratio was assessed from the payer's perspective, with the focus on inpatient care costs and using the cesarean deliveries avoided (CDA) rate as the primary analysis and the rate of vaginal delivery within 24 h (VD24) as the secondary analysis. RESULTS: Analyses were based on 790 women in each group. Differences between treatment arms were the mean cost per patient of €4410 and €4399, a CDA rate of 80.1% and 77.9% and a VD24 rate of 46.1% and 59.4% for dinoprostone and misoprostol, respectively. Dinoprostone is not cost-effective according to the CDA rate and misoprostol was either a cost-effective or a dominant strategy according to the VD24. CONCLUSION: Misoprostol and dinoprostone have equal cost management with mixed efficacy according to the clinical outcome used. Finally, misoprostol may be an attractive option for hospitals as the price is lower and it is easier to use. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01765881.

Healthcare Costs Associated with Potentially Inappropriate Medication Prescribing Detected by Computer Algorithm Among Older Patients.

INTRODUCTION: Potentially inappropriate medication prescribing (PIP) among older patients is associated with an increased risk of adverse events and hospitalization, and sometimes increased healthcare costs. OBJECTIVE: The aim of this study was to explore the association between healthcare costs and PIP exposure among older patients. METHODS: Analyses were conducted using data from the Multidomain Alzheimer Preventive Trial (MAPT). A computer algorithm was constructed to detect PIP based on various different explicit criteria-based tools, and the results were expressed in number of medication-related potential non-compliances (MRNCs). A prescription was considered potentially inappropriate if there were one or more MRNCs. We performed a cost analysis from the French National Health Insurance perspective, and also performed a multivariate analysis to identify the association between healthcare costs and PIP (number of MRNCs). RESULTS: The computer algorithm analyzed medication prescribing from included patients (N = 1525 aged 75.3 ± 4.4 years; 64% women [n = 978]). PIP was associated with increased total healthcare costs and non-medication healthcare costs after adjusting for potential confounders. We also noted that healthcare costs tended to increase with the number of MRNCs. The mean additional healthcare costs were €517, €921, and €1669 per patient and year for patients with one or two MRNCs, three or four MRNCs, and five or more MRNCs, respectively, in comparison with patients with appropriate medication prescriptions. CONCLUSION: These observations led us to conclude that interventions focused on reducing PIP could result in savings. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00672685.

Antibiotic Discovery and Resistance: The Chase and the Race.

The history of antimicrobial resistance (AMR) evolution and the diversity of the environmental resistome indicate that AMR is an ancient natural phenomenon. Acquired resistance is a public health concern influenced by the anthropogenic use of antibiotics, leading to the selection of resistant genes. Data show that AMR is spreading globally at different rates, outpacing all efforts to mitigate this crisis. The search for new antibiotic classes is one of the key strategies in the fight against AMR. Since the 1980s, newly marketed antibiotics were either modifications or improvements of known molecules. The World Health Organization (WHO) describes the current pipeline as bleak, and warns about the scarcity of new leads. A quantitative and qualitative analysis of the pre-clinical and clinical pipeline indicates that few antibiotics may reach the market in a few years, predominantly not those that fit the innovative requirements to tackle the challenging spread of AMR. Diversity and innovation are the mainstays to cope with the rapid evolution of AMR. The discovery and development of antibiotics must address resistance to old and novel antibiotics. Here, we review the history and challenges of antibiotics discovery and describe different innovative new leads mechanisms expected to replenish the pipeline, while maintaining a promising possibility to shift the chase and the race between the spread of AMR, preserving antibiotic effectiveness, and meeting innovative leads requirements.
