Abstract

International audience; This review outlines the use of documentary evidence of historical flood events in contemporary flood frequency estimation in European countries. The study shows that despite widespread consensus in the scientific literature on the utility of documentary evidence, the actual migration from academic to practical application has been limited. A detailed review of flood frequency estimation guidelines from different countries showed that the value of historical data is generally recognised, but practical methods for systematic and routine inclusion of this type of data into risk analysis are in most cases not available. Studies of historical events were identified in most countries, and good examples of national databases attempting to collate the available information were identified. The conclusion is that there is considerable potential for improving the reliability of the current flood risk assessments by harvesting the valuable information on past extreme events contained in the historical data sets.; Cet article présente une revue de l'utilisation de l'information documentaire sur les crues historiques par les pays européens pour l'analyse fréquentielle des crues. L'étude montre que, malgré l'existence d'un consensus scientifique sur l'intérêt de ce type d'information, son utilisation reste encore limitée d'un point de vue opérationnel. Si les guides pratiques sur l'estimation des crues mentionnent en général bien l'intérêt de l'information historique, il existe encore peu de logiciel disponible utilisant cette information. Des travaux sont en cours dans plusieurs pays pour constituer des bases de données nationales sur les crues historiques. La conclusion est qu'il y aurait un fort bénéfice à exploiter ces informations pour l'estimation du risque de crue.

Abstract

Climate change has led to concerns about increasing river floods resulting from the greater water-holding capacity of a warmer atmosphere1. These concerns are reinforced by evidence of increasing economic losses associated with flooding in many parts of the world, including Europe2. Any changes in river floods would have lasting implications for the design of flood protection measures and flood risk zoning. However, existing studies have been unable to identify a consistent continental-scale climatic-change signal in flood discharge observations in Europe3, because of the limited spatial coverage and number of hydrometric stations. Here we demonstrate clear regional patterns of both increases and decreases in observed river flood discharges in the past five decades in Europe, which are manifestations of a changing climate. Our results—arising from the most complete database of European flooding so far—suggest that: increasing autumn and winter rainfall has resulted in increasing floods in northwestern Europe; decreasing precipitation and increasing evaporation have led to decreasing floods in medium and large catchments in southern Europe; and decreasing snow cover and snowmelt, resulting from warmer temperatures, have led to decreasing floods in eastern Europe. Regional flood discharge trends in Europe range from an increase of about 11 per cent per decade to a decrease of 23 per cent. Notwithstanding the spatial and temporal heterogeneity of the observational record, the flood changes identified here are broadly consistent with climate model projections for the next century4,5, suggesting that climate-driven changes are already happening and supporting calls for the consideration of climate change in flood risk management. Analysis of a comprehensive European flood dataset reveals regional changes in river flood discharges in the past five decades that are consistent with models suggesting that climate-driven changes are already happening.

Abstract

Objectives: This study aimed to investigate the willingness to pay (WTP) for a hypothetical vaccine and its associated determinants among the Lebanese general population during one of the peak episodes during the coronavirus disease 2019 (COVID-19) pandemic in Lebanon., Methods: An online survey was developed and delivered to the Lebanese general population. The questionnaire included the participants' sociodemographic characteristics, financial situation, attitude toward vaccination, and WTP for the hypothetical vaccine. The study was based on the contingent valuation method., Results: Among 500 individuals solicited, 352 individuals agreed to participate (participation rate = 70.4%); among them, 66% were between 18 and 45 years old, and 54% were women. Notably, 78.1% of the respondents were ready to pay for this hypothetical vaccine even if the vaccine will not be covered. The maximum WTP of the Lebanese population was approximately $60 ± $66 (range $3-$500) after excluding extreme values in the sensitivity analysis and ranged between $3 and $500. WTP was associated with the severity of COVID-19 (P<.001), the education level (P=.001), and the place to live during the lockdown (P=.045). There was an association between family income and WTP (P=.004) with a weak correlation., Conclusions: The WTP was comparable with other studies and highly associated with the level of education, the household income, living in the city during the lockdown, and the perceived severity of COVID-19. These findings can help in understanding COVID-19 vaccination acceptance and WTP in Lebanon., (Copyright © 2021 ISPOR--The professional society for health economics and outcomes research.

14. Does hospital setting post robotic fellowship training affect outcomes? A multi-institutional comparison of initial outcomes between academic and community settings.

Abstract

The effect of practice setting on skill development post robotic fellowship training is currently unknown. We sought to compare learning curves between a high-volume academic center and a similar volume community hospital, in the setting of building a new robotic prostatectomy program. In addition, we sought to characterize benchmarks for learning curve development for post-fellowship training in robotic surgery. At two institutions, one academic (AC) and the other in the community (CO), the first 150 patients who underwent robotic laparoscopic prostatectomy over a period of 1 year were evaluated. We compared the following outcomes, operative time (OT), estimated blood loss (EBL), and positive surgical margin (PSM) rates, by two surgeons. Both surgeons completed the same surgical robotic fellowship in the same year. Cases were divided by tertile and primary outcomes measures were compared. Demographic data were similar between the two groups. Statistical differences were seen in age, preoperative Sexual Health Inventory for Men score, clinical and pathologic stage, and bladder neck reconstruction rate (p < 0.05). Overall, there was no significant difference in OT between AC (174 min) and CO (181 min) (p = 0.1099). Both EBL and PSM were lower in the AC (155 vs. 197 ml, p < 0.001 and 10 vs. 26 %, p < 0.05). The difference in OT was significant only in the first tertile of cases (AC 168 min vs. CO 193 min, p = 0.002). However, OT increased by 13 min in AC and decreased by 22 min in CO, when comparing the first and last tertile. EBL was different between AC (161ml) and CO (212 ml) only in the first tertile of cases (p = 0.002). Both AC and CO had increased EBL over the last tertile of cases (16.2 vs. 26.5 ml, respectively). These results demonstrate minor differences in outcomes between the two practice settings. Fellowship training in robotic surgery demonstrates a shorter learning curve towards achieving proficiency. Larger and longer term series will be required to assess functional outcomes and time to proficiency.
