Abstract
AIM The association between infection with SARS-CoV-2 and the development of new-onset type 1 diabetes mellitus (T1DM) is unclear. The aim of this study was to examine the impact of the Covid-19 pandemic on the hospitalization rates for new-onset T1DM and diabetic ketoacidosis at diagnosis, in metropolitan France. METHODS This nationwide retrospective cohort study included hospital data on all patients aged 1 to 35 years old, hospitalized in France due to onset of T1DM, in 2020 and 2021 compared to 2019. RESULTS Apart from a decrease during the lockdown in 2020, the number of hospitalizations due to new-onset T1DM was not significantly different in 2020 and 2021 than it was in 2019. In the regions most affected by Covid-19 and covering 7,995,449 inhabitants aged from 1 to 35 years old, standardized hospitalization rates were not significantly different in 2020 and in 2021 compared with 2019. The number of hospitalizations for diabetic ketoacidosis at diagnosis was not significantly different after week 14 in 2020 and in 2021 compared with 2019. CONCLUSION In this nationwide study, the incidence of hospitalizations for new-onset T1DM and the incidence of diabetic ketoacidosis at diagnosis was not increased during the Covid-19 pandemic in 2020 and 2021. Our results support the fact that infection with SARS-CoV-2 does not promote the development of T1DM.

Abstract
BACKGROUND/AIMS The COVID-19 crisis and the decisions made regarding population lockdown may have changed patient care. We aimed to investigate the incidence rate of rhegmatogenous retinal detachment (RRD) cases during the COVID-19 lockdown period. METHODS In this nationwide database study, we identified hospital and clinic admissions of French residents for a first episode of RRD in France from 2017 to the lockdown period in 2020. The monthly hospital incidence rates of RRD procedures per 100 000 inhabitants before, during and after lockdown were computed for the whole country. Finally, we assessed the influence of viral incidence on the RRD incidence rate, comparing two regions with highly contrasting viral penetration. RESULTS From January to July, the average monthly national hospital incidence rate of RRD decreased from a mean of 2.59/100 000 inhabitants during 2017-2019 to 1.57/100 000 inhabitants in 2020. Compared with 2019, during the 8-week lockdown period in 2020, a 41.6% decrease in the number of RRD procedures was observed (p<0.001) with the weekly incidence of RRD decreasing from 0.63/100 000 inhabitants in 2019 to 0.36/100 000 inhabitants. During the 4-month post-lockdown period, no increased activity related to postponed procedures was observed. No difference was found in the rate of RRD surgery when comparing two regions with highly contrasting viral incidence. CONCLUSION Containment may have been responsible for a decrease in the number of surgical procedures for RRD, without any compensating post-lockdown activity in France. These results might help increase awareness of the management of RRD emergencies.

Topical Antibiotic Prophylaxis and Intravitreal Injections: Impact on the Incidence of Acute Endophthalmitis-A Nationwide Study in France from 2009 to 2018. Pharmaceutics 2022; 14:pharmaceutics14102133.

Abstract
Background: The dramatic increase in intravitreal injections (IVTs) has been accompanied by a greater need for safer procedures. The ongoing debate about topical antibiotic prophylaxis after IVTs emphasizes the importance of large-scale studies. We aimed to study the role of topical antibiotic prophylaxis in reducing the risk of acute endophthalmitis after IVTs. Methods: Population-based cohort study, in France, from 2009 to 2018, including all French patients receiving IVTs of corticosteroids or anti-VEGF agents. Results: A total of 5,291,420 IVTs were performed on 605,434 patients. The rate of topical antibiotic prophylaxis after IVTs progressively decreased during the study period, with a sharp drop in 2014 (from 84.6% in 2009 to 27.4% in 2018). Acute endophthalmitis occurred in 1274 cases (incidence rate = 0.0241%). Although antibiotic prophylaxis did not alter the risk of endophthalmitis (p = 0.06), univariate analysis showed an increased risk after fluoroquinolone and aminoglycoside prophylaxis. This increased risk was not found in multivariate analysis. However, we observed an increased risk related to the use of fixed combinations of fluoroquinolones and aminoglycosides with corticosteroids (IRR = 1.89; 95% CI = 1.57–2.27%, antibiotics combined with corticosteroids). Conclusion: These results are consistent with the literature. Endophthalmitis rates after IVTs did not decrease with topical antibiotic prophylaxis. The use of a combination of antibiotics and corticosteroids doubles the risk of endophthalmitis and should be avoided. Avoiding antibiotic prophylaxis would reduce the costs and the potential risks of antibiotic resistance.

Abstract
The COVID-19 pandemic modified the management of myocardial infarction (MI) and stroke. We aimed to evaluate the effect of the COVID-19 pandemic on the volume and spatial distribution of hospitalizations for MI and stroke, before, during and after the first nationwide lockdown in France in 2020, compared with 2019. Hospitalization data were extracted from the French National Discharge database. Patient’s characteristics were compared according to COVID-19 status. Changes in hospitalization rates over time were measured using interrupted time series analysis. Possible spatial patterns of over or under-hospitalization rates were investigated using Moran’s indices. We observed a rapid and significant drop in hospitalizations just before the beginning of the lockdown with a nadir at 36.5% for MI and 31.2% for stroke. Hospitalization volumes returned to those seen in 2019 four weeks after the end of the lockdown, except for MI, which rebounded excessively. Older age, male sex, elevated rate of hypertension, diabetes, obesity and mortality characterized COVID-19 patients. There was no evidence of a change in the spatial pattern of over- or under-hospitalization clusters over the three periods. After a steep drop, only MI showed a significant rebound after the first lockdown with no change in the spatial distribution of hospitalizations.

Abstract
PURPOSE To report the incidence of postoperative rhegmatogenous retinal detachment after macular surgery in France between 2006 and 2016 and identify associated factors. DESIGN Nationwide population-based cohort study. METHODS All surgical procedures for an epiretinal membrane or a macular hole performed in France from January 1, 2006 to October 31, 2016 were identified in the French national administrative database (Programme de Médicalisation des Systèmes d'Information). We investigated the incidence of rhegmatogenous retinal detachment occurring within 90 days of a macular surgical procedure. RESULTS From January 1, 2006 to October 31, 2016, 152,034 macular surgical procedures for epiretinal membranes or macular holes were recorded in France. We identified 3,605 cases of rhegmatogenous retinal detachment occurring within 90 days of the procedure. The incidence of rhegmatogenous retinal detachment was 2.37% overall, 1.95% for epiretinal membrane surgery and 3.43% for macular hole surgery. In multivariable Poisson regression analysis, rhegmatogenous retinal detachment was associated with macular hole surgery (incidence rate ratio [IRR], 1.76; 95% CI, 1.63-1.90; P < .001), history of cataract extraction in the previous year (IRR, 1.20; 95% CI, 1.08-1.34; P = .001), age < 60 years (P < .001), and male gender (IRR, 1.63; 95% CI, 1.51-1.76; P < .001). CONCLUSIONS The incidence of rhegmatogenous retinal detachment within 90 days of macular surgery was 2.37% overall in France between 2006 and 2016 and it was higher for macular hole surgery than for epiretinal membrane surgery.

Abstract
OBJECTIVE To describe the causes of postoperative acute endophthalmitis at the national level longitudinally. DESIGN Cohort study from 2009 to 2018 in France. PARTICIPANTS Patients diagnosed with acute endophthalmitis after intraocular procedures. METHODS The French medical-administrative database was used. Endophthalmitis cases and intraocular procedures were identified based on billing codes in all French hospitals and private practices. MAIN OUTCOME MEASURES The incidence of acute endophthalmitis within 42 days of the procedure. RESULTS From January 1, 2009, to October 31, 2018, 7522 cases of acute endophthalmitis occurred after 14 438 854 intraocular procedures. Most cases occurred after standalone cataract surgery (4808 cases for 7 316 077 procedures; 63.92%), followed by after intravitreal (IVT) injections (1296 cases for 5 455 631 IVT injections; 17.23%), vitreoretinal surgery (698 for 442 263 procedures; 9.28%), anterior segment surgery (245 cases; 3.26%), combined cataract and vitreoretinal surgery (191 cases; 2.54%), cornea surgery (142 cases; 1.89%), and glaucoma surgery (80 cases; 1.06%). The overall incidence of acute endophthalmitis was 1 per 1920 procedures (0.0521%; 95% confidence interval [CI], 0.0520-0.0522). The surgery with the highest incidence of endophthalmitis was scleral and globe surgery, with an incidence of 0.1827% (95% CI, 0.1757-0.1898), followed by vitreoretinal surgery combined with cataract surgery, with an incidence of 0.1685% (95% CI, 0.1663-0.1706). The incidence of endophthalmitis after IVT injections was stable over the study period, and patients receiving IVT injections were the oldest, aged 75.4 years (standard deviation, 12.0 years; P < 0.001). The onset of endophthalmitis after IVT procedures, i.e, after receiving IVT injections or undergoing vitreoretinal surgery, was earlier than that after the other procedures (P < 0.001). CONCLUSIONS The profile of patients referred for acute endophthalmitis has been evolving over the past decade, with a decrease in the raw number of endophthalmitis cases after cataract surgery as opposed to an increase in the number of patients presenting with endophthalmitis after IVT injections.

Abstract
Background. The impact of the COVID-19 pandemic on hospitalization for cardiac infections is not well known. We aimed to evaluate the nationwide trends in hospital stays for myocarditis and endocarditis cases before, during and after the nationwide lockdown for the COVID-19 pandemic in France. We then aimed to describe the proportion of myocarditis and endocarditis patients with and without COVID-19 and their clinical characteristics. Methods. Hospitalized cases of cardiac infection were extracted from the French National Discharge database, which collects the medical records of all patients discharged from all public and private hospitals in France. Age, sex, and available cardiovascular risk factors were compared between stays with and without COVID-19 during the lockdown. Results. The number of myocarditis cases was 11% higher in 2020, compared to the average of the three prior years. In 2020, 439 of 3727 cases of myocarditis were associated with COVID-19. For endocarditis, there was an increase in cases by 7% in 2020 versus prior years. For endocarditis, 3% (240 of 8128 cases) of patients with endocarditis had COVID-19. For myocarditis, older age, hypertension, diabetes, obesity, and atrial fibrillation were more frequent in patients with COVID-19 than in those without. For endocarditis, only hypertension was more frequent in patients with COVID-19 than in those without. Conclusion. Our study reports an increase in hospitalizations for both myocarditis and endocarditis in 2020, possibly related to the COVID-19 pandemic. Interestingly, the trends differ according to the COVID-19 status. Knowledge of the factors associating myocarditis or endocarditis and COVID-19 may improve the quality and the type of monitoring for people with COVID-19, the identification of patients at risk of cardiac infections, and the treatment of COVID-19 patients.

Abstract
Background: There are still gaps regarding the impact of the nationwide lockdown on non-COVID-19 emergency hospitalizations. This study aims to describe the trends in hospitalizations for cardiovascular surgical emergencies in France, before, during and after the first lockdown. Materials and Methods: All adults admitted for mechanical complications of myocardial infarction (MI), aortic dissection, aortic aneurysm rupture, acute and critical limb ischemia, circulatory assistance, heart transplantation and major amputation were included. This retrospective cohort study used the French National Hospital Discharge database. The numbers of hospitalizations per month in 2020 were compared to the previous three years. Results: From January to September 2020, 94,408 cases of the studied conditions were reported versus 103,126 in the same period in 2019 (−8.5%). There was a deep drop in most conditions during the lockdown, except for circulatory assistance, which increased. After the lockdown, mechanical complications of MI and aortic aneurysm rupture increased, and cardiac transplantations declined compared with previous years. Conclusion: We confirmed a deep drop in most cardiovascular surgical emergencies during the lockdown. The post-lockdown period was characterized by a small over-recovery for mechanical complications of MI and aortic aneurysm rupture, suggesting that many patients were able to access surgery after the lockdown.

Abstract
Venous thromboembolism is highly prevalent in lung cancer patients. Low molecular weight heparins are recommended for long term treatment of cancer associated venous thromboembolism. Direct oral anticoagulants are however an interesting alternative as they are administered orally and don't require monitoring. There are currently studies comparing both their efficacy and tolerance for cancer patients and more and more guidelines suggest considering direct oral anticoagulants for cancer associated venous thromboembolism treatment. The objective of this study was to evaluate the budgetary impact that direct oral anticoagulants use would have for lung cancer associated venous thromboembolism treatment and prevention in France. An economic model was made to evaluate the cost of venous thromboembolism treatment and prevention among patients with primary lung cancer in France by two strategies: current guidelines versus direct oral anticoagulants use. The model was fed with clinical and economic data extracted from the French national health information system. The analysis was conducted from the national mandatory Health insurance point of view. The time horizon of the study was the evaluation of the annual management cost. Lung cancer associated venous thromboembolism management's mean cost was estimated of 836€ per patient, that is a total cost of about 40 million euros per year at a national level. A 76% decrease of this cost can be expected with direct oral anticoagulants use. However, despite their benefits, these treatments raise new issues (medication interactions, bleeding management), and would likely not be recommended for all patients.

Abstract
AIMS/HYPOTHESIS The aim of this study was to examine the impact of the COVID-19 epidemic on the hospitalization rates for diabetic foot ulcer (DFU), osteomyelitis and lower limb revascularization procedure in people with DFU. METHODS This nationwide retrospective cohort study included hospital data on all people hospitalized in France for diabetes in weeks 2-43 in 2020, including the COVID-19 lockdown period, compared to same period in 2019. RESULTS The number of hospitalizations for DFU decreased significantly in weeks 12-19 (during the lockdown) (p < 10-4 ). Hospitalization for foot osteomyelitis also decreased significantly in weeks 12-19 (p < 10-4 ). The trend was the same for lower limb amputations and revascularizations associated with DFU or amputation. CONCLUSIONS/INTERPRETATION The marked drop in hospitalization rates for DFU, osteomyelitis and lower limb revascularization procedures in people with DFU observed in France during the lockdown period suggests that COVID-19 was a barrier to DFU care, and may illustrate the combined deleterious effects of hospital overload and changes in health-related behaviour.

Abstract
AIMS To investigate the annual and monthly hospital incidence rate of rhegmatogenous retinal detachments (RRDs) from 2010 to 2016 in France at the national and regional levels. METHODS In this nationwide database study, we identified hospital and clinic admissions of French residents for a first episode of RRD in France during 2010-2016 from the national administrative database. The annual and monthly hospital incidence rates of RRD per 100 000 population were calculated for the whole country and for each region. RESULTS The average annual national hospital incidence rate of RRD was 21.97±1.04 per 100 000 population. The annual national hospital incidence rate of RRD was the lowest in 2010 (20.91 per 100 000 population) after which it increased until 2015 (23.55 per 100 000 population). The average monthly national RRD hospital incidence rate was the highest in June (2.03±0.12 per 100 000 population) and the lowest in August (1.60±0.09). The average annual age-standardised and sex-standardised regional hospital incidence rate was the highest in Guadeloupe and Pays de la Loire (28.30±2.74 and 26.13±0.84 per 100 000 population, respectively) and the lowest in French Guiana and Martinique (15.51±3.50 and 17.29±2.12 per 100 000 population, respectively). CONCLUSIONS The average annual national hospital incidence rate of RRD increased from 2010 to 2015. The hospital incidence rate of RRD seemed to vary according to season and geographical location.

Abstract
BACKGROUND AND PURPOSE In France, the entire population was put under a total lockdown from March 17 to May 11, 2020 during the peak of the coronavirus disease 2019 (COVID-19) pandemic. Whether the lockdown had consequences on the management of medical emergencies such as stroke and transient ischemic attack (TIA) has yet to be fully evaluated. This article describes hospitalization rates for acute stroke in 2 French regions that experienced contrasting rates of COVID-19 infection, before, during, and after the nationwide lockdown (January to June 2020). METHODS All patients admitted for acute stroke/TIA into all public and private hospitals of the 2 study regions were included. Data were retrieved from the National Hospitalization Database (PMSI). In the most affected region (Grand-Est), the hospitalization rates observed in April 2020 were compared with the rates in the same period in the least affected region (Occitanie) and in the 3 prior years (2017-2019). RESULTS There was a significant decline in hospitalization rates for stroke/TIA within the region most affected by COVID-19 during the month of April 2020 compared with previous years, while no significant change was seen in the least affected region. After lockdown, we observed a fast rebound in the rate of hospitalization for stroke/TIA in the most affected region, contrasting with a slower rebound in the least affected region. In both regions, patients with COVID-19 stroke more frequently had ischemic stroke, a nonsignificant greater prevalence of diabetes, they were less frequently admitted to stroke units, and mortality was higher than in patients without COVID-19. CONCLUSIONS Our results demonstrates a significant drop in stroke/TIA hospitalizations and a fast recovery after the end of the French lockdown in the most affected region, while the least affected region saw a nonsignificant drop in stroke/TIA hospitalizations and a slow recovery. These results and recommendations could be used by the health authorities to prepare for future challenges.

Abstract
The aim of our validation study was to assess the quality of hospital data for perinatal algorithms on a national level. In each hospital, we selected 150 discharge abstracts of delivery (after 22 weeks of gestation), in 2014, and their corresponding medical records. Overall, 23 hospitals were included and 3,246 discharge abstracts were studied. This first national validation study of several case-funding algorithms using various perinatal variables suggests that the French national hospital discharge abstracts database is an appropriate data source for epidemiological studies.

Abstract
Background Venous thromboembolism (VTE) is highly prevalent in cancer patients and can cause severe morbidity. VTE treatment is essential, but anticoagulation increases the risk of major bleeding. The purpose was to evaluate the impact of VTE and major bleeding on survival and to identify significant risk factors for these events in lung cancer patients. Methods Data were extracted from a permanent sample of the French national health information system (including hospital and out-of-hospital care) from 2009 to 2016. All episodes of VTE and major bleeding events within one year after cancer diagnosis were identified. A Cox model was used to analyse the effect of VTE and major bleeding on the patients’ one-year survival. VTE and major bleeding risk factors were analysed with a Fine and Gray survival model. Results Among the 2553 included patients with lung cancer, 208 (8%) had a VTE episode in the year following diagnosis and 341 (13%) had major bleeding. Almost half of the patients died during follow-up. Fifty-six (60%) of the patients presenting with pulmonary embolism (PE) died, 48 (42%) of the patients presenting with deep vein thrombosis (DVT) alone died and 186 (55%) of those presenting with a major bleeding event died. The risk of death was significantly increased following PE and major bleeding events. VTE concomitant with cancer diagnosis was associated with an increased risk of VTE recurrence beyond 6 months after the first VTE event (sHR = 4.07 95% CI: 1.57–10.52). Most major bleeding events did not appear to be related to treatment. Conclusion VTE is frequent after a diagnosis of lung cancer, but so are major bleeding events. Both PE and major bleeding are associated with an increased risk of death and could be indicators of lung cancer mortality.

Abstract
OBJECTIVE The aim of our validation study was to assess the metrological quality of hospital data for perinatal algorithms on a national level. DESIGN Validation study. SETTING This was a multicentre study of the French medicoadministrative database on perinatal indicators. PARTICIPANTS In each hospital, we selected 150 discharge abstracts for delivery (after 22 weeks of gestation), in 2014, and their corresponding medical records. Overall, 22 hospitals were included. INTERVENTIONS A single investigator performed blind data collection from medical records in order to compare data from discharge abstracts with data from medical records. Finally, 3246 discharge abstracts were studied. PRIMARY AND SECONDARY OUTCOME MEASURES Seventy items, including maternal and delivery characteristics and maternal morbidity, were collected for each delivery stay. RESULTS The concordance rate of maternal age at delivery was 94.8% (95% CI 93.8 to 95.4). Combining the two forms of pre-existing diabetes, the algorithm presented a PPV of 65.9% and a sensitivity of 75.7%. The concordance rate of gestational age at delivery was 91.8% (90.9 to 92.7). Regarding gestational diabetes, the PPV was 80.8% (79.4 to 82.2) and the sensitivity was 79.5% (78.1 to 80.9). Regardless of the algorithm explored, the PPV for vaginal delivery was over 99%. For the diagnosis codes corresponding to immediate postpartum haemorrhage, the PPV was 77.7% (76.3 to 79.1) and the sensitivity was 75.5% (74.0 to 77.0). The algorithm for stillbirth presented a PPV of 89.4% (88.3 to 90.5) and a sensitivity of 95.4% (94.7 to 96.1). CONCLUSIONS This first national validation study of many perinatal algorithms suggests that the French national hospital database is an appropriate data source for epidemiological studies, except for some indicators which presented low PPV and/or sensitivity.

Abstract
PURPOSE To report the incidence of acute postoperative endophthalmitis (POE) after macular surgery in France between 2006 and 2016 and to identify associated factors. METHODS This retrospective database study included all hospital discharge records involving a surgical procedure for an epiretinal membrane or a macular hole in France from January 2006 to October 2016. Acute POE was identified by two codes in the tenth edition of the International Classification of Diseases within 42 days of a macular surgical procedure in the French national administrative database. RESULTS In France, 152 034 macular surgical procedures for epiretinal membranes or macular holes were recorded from 1 January 2006 to 31 October 2016. Suspected acute POE was reported in 381 cases. The incidence of POE was 0.25% overall, 0.30% for epiretinal membrane surgery and 0.14% for macular hole surgery. In multivariable Poisson regression analysis, epiretinal membrane surgery was associated with POE [incidence rate ratio (IRR), 2.24; 95% CI, 1.62-3.11; p < 0.001]. For epiretinal membrane surgery, the 2010-2011 period was significantly associated with a higher risk of POE (IRR, 1.66; 95% CI, 1.13-2.42; p = 0.03). CONCLUSION The incidence of POE after macular surgery was 0.25% overall in France between 2006 and 2016 and twice higher for epiretinal membrane surgery than for macular hole surgery. For epiretinal surgery only, the incidence of POE was higher in 2010-2011 (period of the switch to transconjunctival vitrectomy) than in the rest of the study period.

Abstract
BACKGROUND Children born to mothers with IBD may be exposed to anti-TNFα agents antenatally. Current European guidelines recommend postponing live vaccines until after 6 months of life in this population. Data on the safety of live vaccines administration in the first year of life of these children are sparse with one reported fatality following bacillus Calmette-Guerin (BCG) administration. AIMS To describe the use and safety of vaccines administered in children born to mothers with IBD and exposed antenatally to anti-TNFα agents METHODS: Data from children born to mothers with IBD between 2013 and 2014 were collected retrospectively from the French Health Insurance Database. Vaccines recommended before or at 1 year of age were considered. RESULTS Among 4741 children, 670 (14.1%) were exposed to anti-TNFα agents antenatally, with concomitant thiopurines in 16.0% (n = 107) and steroids in 19.3% (n = 214). Among these 670 children, 315 (47%) were exposed up to delivery. Exposed children were less likely than non-exposed to receive BCG (88/670, 13.1% vs 780/4071, 19.2% respectively, P < .05) and received it later in life (months, mean ± SD, 4.3 ± 3.9 and 2.4 ± 2.9 respectively, P < .001). In exposed children, 64/88 (73%) received BCG vaccination before 6 months of age, but with no BCG-related severe adverse event observed during the first year. Uptake of other vaccines recommended before 6 months was above 85% in both groups. CONCLUSION In children exposed antenatally to anti-TNFα agents, vaccinations are often not postponed in keeping with the recommendations, but no BCG-related severe adverse events were reported in children vaccinated before 6 months of life.

Abstract
Importance The number of patients affected by retinal diseases treated with intravitreal injections (IVTs) has resulted in a rapidly growing number of procedures. One of the worst complications after these injections is endophthalmitis. Objective To evaluate the incidence of acute endophthalmitis after IVTs of corticosteroids or anti-vascular endothelial growth factor (anti-VEGF) agents. Design, Setting, and Participants This population-based cohort study included patients undergoing IVTs from January 1, 2012, through December 31, 2015, in France. Data were acquired from the French medical-administrative database (Système National d'Information Inter-Régime de l'Assurance Maladie), which collects hospitalization discharge abstracts and out-of-hospital care information for the whole country. Data were analyzed from March through July 2017. Exposures Intravitreal injections of corticosteroid or anti-VEGF agents. Main Outcomes and Measures Incidence of acute endophthalmitis within 6 weeks after IVT by means of billing codes from a national database. Results During the study period, 1 811 977 IVTs of corticosteroids or anti-VEGF agents performed on 254 927 patients (60.4% female; median age, 79 years [interquartile range, 70-85 years]) were analyzed. A total of 444 acute endophthalmitis cases (crude incidence, 0.0245%) were recorded. In multivariable analysis, which did not include adjustment for when the endophthalmitis occurred during the study period, the risk of endophthalmitis was lower in male patients (incidence rate ratio [IRR], 0.78; 95% CI, 0.63-0.96; P = .02), higher for corticosteroids than for anti-VEGF agents (IRR, 3.21; 95% CI, 2.33-4.44; P < .001), and higher for nonprefilled syringes of anti-VEGF medications than prefilled syringes for ranibizumab (IRR, 1.63; 95% CI, 1.15-2.30) and aflibercept (IRR, 1.82; 95% CI, 1.25-2.66; P < .001). Conclusions and Relevance The findings from this study of a nationwide database appear to have confirmed the low incidence rate of acute endophthalmitis after IVTs of corticosteroids or anti-VEGF agents. Although an association may not necessarily indicate a cause and effect, the risk for acute endophthalmitis after IVTs appeared to be higher for corticosteroids compared with anti-VEGF agents, while a lower risk of endophthalmitis appeared to be found with prefilled syringes of anti-VEGF medications.

Abstract
BACKGROUND Multiple pregnancies (where more than one fetus develops simultaneously in the womb) are systematically excluded from studies of the impact of air pollution on pregnancy outcomes. This study aims to analyze, in a population of multiple pregnancies, the relationship between fetal growth restriction (FGR), small for gestational age (SGA) and exposure to air pollution in moderately polluted cities. METHODS All women with multiple pregnancies living in the city of Besançon or in the urban area of Dijon and who delivered at a university hospital between 2005 and 2009 were included. FGR and SGA were obtained from medical records. Outdoor residential nitrogen dioxide (NO2) exposure was assessed using the mother's address, considering a 50 m radius buffer over the following defined pregnancy periods: each trimester, entire pregnancy and two months before delivery. Logistic regression analyses were performed. RESULTS This study included 249 multiple pregnancies with 506 newborns. The median of NO2 concentration considering a 50 m radius buffer during entire pregnancy was 23.1 μg/m3 (minimum at 10.1 μg/m3 and maximum at 46.7 μg/m3). No association was observed between NO2 and SGA whatever the pregnancy period (the odds ratio (OR) range 0.78 to 0.88). Regarding FGR, the OR associated with an increase of 10 μg/m3 of NO2 exposure during entire pregnancy was 1.52 (95% Confidence Interval (CI): 1.02-2.26). Similar results were observed for NO2 exposure during the various pregnancy periods. CONCLUSIONS These results are in line with an association between NO2 and fetal growth in multiple pregnancies for an exposure mostly below the threshold set out in European legislation.

Abstract
PURPOSE To assess the incidence of acute postoperative endophthalmitis (POE) after cataract surgery combined with corneal, glaucoma or vitreoretinal surgical procedures from 2005 to 2014 in France. METHODS In this cohort study, acute POE occurring within 6 weeks after surgery was identified by means of billing codes recorded in a national database in patients operated for cataract extraction with phacoemulsification, or corneal, glaucoma or vitreoretinal surgical procedures, either combined or stand-alone. RESULTS From January 2005 to December 2014, up to 6 260 477 eyes underwent phacoemulsification cataract surgery as a single procedure and 115 468 eyes underwent phacoemulsification combined with corneal, glaucoma or vitreoretinal surgical procedures. The crude incidence of acute POE after stand-alone or combined cataract surgery was 0.102% and 0.149%, respectively. In multivariate Poisson analysis, combined surgery taken as a whole was at higher risk than cataract stand-alone surgery, with an adjusted incidence rate ratio (IRR) (95% CI) of 1.38 (1.11 to 1.70; p=0.0054). Glaucoma surgeries were associated with a lower acute POE incidence compared with phacoemulsification, conversely to vitreoretinal surgical procedures: IRR 0.63 (0.47 to 0.85; p<0.001) and IRR 1.78 (1.58 to 2.01; p<0.001), respectively. CONCLUSION A higher incidence of acute POE after combined cataract surgery than after cataract surgery done as a stand-alone procedure was observed based on the French nationwide medical-administrative database. The incidence of acute POE after combined surgery was related to the type of surgery performed simultaneously with cataract extraction.

Abstract
OBJECTIVES To establish non-customized and customized birth-weight curves of single and uncomplicated pregnancies according to gestational age. MATERIALS AND METHODS We used data for 64,173 mother-infants pairs from the Burgundy perinatal network database (France) over the period 2005-2013. A validated procedure was used to link mothers with their newborns, and maternal and fetal pathologies likely to affect birth weight were excluded. Multiple regression analysis with covariate selection was used to build a customized growth curve with maternal and fetal parameters. RESULTS Using this methodology, three different curves were generated: an unadjusted curve for birth weight, named B0, an curve adjusted for fetal gender, named B1 and a curve adjusted for fetal and maternal parameters (fetal gender, maternal height, weight and parity), named B2. CONCLUSION We present curves showing an original distribution of birth weights for the French population in order to improve the diagnosis of small for gestational age. These curves are not based on the Gardosi in utero growth model but on actual birth weights, thus limiting bias. Nevertheless, the minimum gestational age was 25weeks as there was an insufficient number of live-borns in small gestational ages.

Abstract
PURPOSE To report the trends in operating room-based glaucoma procedures from 2005 to 2014 in France. METHODS We identified operating room-based glaucoma procedures (trabeculectomies, deep sclerectomies, aqueous shunts and ciliary body destructions) performed in France from 2005 to 2014 by means of billing codes from a national database. The annual rates and incidence of these procedures per 100 000 inhabitants were analysed globally and in three age groups: 0-14 years, 15-59 years and over 60 years. RESULTS The annual rate of trabeculectomies decreased slightly during the study period, while the rate for other surgical techniques (deep sclerectomies, aqueous drainage procedures and ciliary body destructions) increased. The overall rate of glaucoma surgeries was higher in areas with populations of African descent than in areas predominantly composed of Caucasian populations: 1.60 (95% CI 1.51 to 1.70, p<0.0001). CONCLUSIONS Trabeculectomy was the most commonly performed operating room-based glaucoma procedure in France from 2005 to 2014. Other modalities such as deep sclerectomies, aqueous drainage procedures and ciliary body destruction gained greater acceptance among French ophthalmologists during this 10-year period.

Abstract
Administrative records in France, especially medical and social records, have huge potential for statistical studies. The NIR (a national identifier) is widely used in medico-social administrations, and this would theoretically provide considerable scope for data matching, on condition that the legislation on such matters was respected.The law, however, forbids the processing of non-anonymized medical data, thus making it difficult to carry out studies that require several sources of social and medical data.We would like to benefit from computer techniques introduced since the 70 s to provide safe linkage of anonymized files, to release the current constraints of such procedures.We propose an organization and a data workflow, based on hashing and cyrptographic techniques, to strongly compartmentalize identifying and not-identifying data.The proposed method offers a strong control over who is in possession of which information, using different hashing keys for each linkage. This allows to prevent unauthorized linkage of data, to protect anonymity, by preventing cumulation of not-identifying data which can become identifying data when linked.Our proposal would make it possible to conduct such studies more easily, more regularly and more precisely while preserving a high enough level of anonymity.The main obstacle to setting up such a system, in our opinion, is not technical, but rather organizational in that it is based on the existence of a Key-Management Authority.

Abstract
OBJECTIVES To analyse episiotomy and perineal tears rates in Burgundy after French National College of Obstetricians and Gynecologists (CNGOF) guidelines in 2005. MATERIALS AND METHOD Multicenter retrospective study, between 2003-2005 (period 1) et 2012-2014 (period 2), conducted on singletons vaginal deliveries, in cephalic presentation from 37 weeks. We compared the episiotomy rate (ER), and perineal lesions in normal deliveries (ND) and instrumental deliveries (ID) between the two periods. RESULTS A total of 74,268 women were included. The overall ER significantly decreased from 35.8 to 16.7% (P<0.01), without increasing third degree perineal tears (0.73% vs. 0.66%) or fourth degree (0.14% vs 0.14%). First degree perineal tears rose (42.1% vs 17.6%, P<0.001), second degree decreased (13.5% vs 20.5%, P<0.001). ER decreased whatever the level of motherhood, healthcare ward, vaginal delivery type, or the instrument used. CONCLUSION Our study found a strong impact in Burgundy of the French guidelines for the practice of restrictive episiotomy for both ND and for ID without increasing sphincter tears and in decreasing spontaneous morbidity.

Abstract
Objective The study was designed to describe the hospital incidences and annual hospitalization rates for venous thromboembolic disease by age and sex in France and the United States on the closest possible methodological bases. Methods French statistics are from the PMSI MCO (Programme de médicalisation des système d'information de médecine, chirurgie et obstétrique (French national hospital discharge register)) national database. These are compiled for each calendar year by collating résumé de sortie anonymisé (RSA, anonymous discharge summary) files forwarded and validated by health establishments with admissions in medicine, surgery, obstetrics, and odontology. They are compared to the data issued from the US National Hospital Discharge Survey which is equivalent to the PMSI in France and uses the International Classification of Diseases-9 for encoding the data. These data were published in the Morbidity, Mortality Weekly Report of the Centre for Disease Control. Results In the US, 547,996 hospital stays involve venous thromboembolic diseases, 348,558 deep venous thrombosis (DVT), and 277,549 pulmonary embolism (PE). Of these 78,511, or 14%, include a diagnosis of both DVT and PE. The hospital incidence of venous thromboembolic disease is 1.4%, DVT 0.9%, and PE 0.7%. In France, of the 26,658,228 annual hospital stays, 273,931 include venous thromboembolic disease, 179,286 DVT, and 139,345 PE while 44,700, i.e. 16.3%, include both DVT and PE. The hospital incidence of venous thromboembolic disease is thus 1.0%, DVT 0.6%, and PE 0.5%. The overall annual hospitalization rates for venous thromboembolic disease, DVT, and PE are respectively 274, 179, and 139 per 100,000 inhabitants in France and 239, 146, and 121 per 100,000 inhabitants in the US. Conclusion Venous thromboembolic diseases occur in France and the US in 1% of all hospital stays and are responsible for an annual hospitalization rate that exceeds 200 per 100,000. The scale of these annual incidences should prompt us to question the quality of prevention put in place and/or its efficacy.

Abstract
PURPOSE To report the incidence of acute postoperative endophthalmitis (POE) after cataract surgery from 2005 to 2014 in France. DESIGN Cohort study. PARTICIPANTS Patients undergoing operation for cataract surgery by phacoemulsification and presenting acute POE. METHODS We identified acute POE occurring within 6 weeks after phacoemulsification cataract surgery and the use of intracameral antibiotic injection during the surgical procedure by means of billing codes from a national database. MAIN OUTCOME MEASURES Incidence of acute POE. RESULTS From January 2005 to December 2014, 6 371 242 eyes in 3 983 525 patients underwent phacoemulsification cataract surgery. The incidence of acute POE after phacoemulsification decreased from 0.145% to 0.053% during this 10-year period; the unadjusted incidence rate ratio (IRR) (95% confidence interval) was 0.37 (0.32-0.42; P < 0.001). In multivariate analysis, intracameral antibiotic injection was associated with a lower risk of acute POE 0.53 (0.50-0.57; P < 0.001), whereas intraoperative posterior capsule rupture, combined surgery, and gender (male) were associated with a higher risk of acute POE: 5.24 (4.11-6.68), 1.77 (1.53-2.05), and 1.48 (1.40-1.56) (P < 0.001), respectively. CONCLUSIONS Access to a national database allowed us to observe a decrease in acute POE after phacoemulsification cataract surgery from 2005 to 2014. Within the same period, the use of intracameral antibiotics during the surgical procedures increased.

Abstract
BACKGROUND In order to assess public health policies for the perinatal period, routinely produced indicators are needed for the whole population. In France, these indicators are used to compare the national public health policy with those of other European countries. French administrative and medical data (PMSI) are straightforward and reliable and may be a valuable source of information for research. This study aimed to measure the quality of PMSI data from three university health centers for core indicators in perinatal health. METHOD PMSI data were compared with medical files in 2012 from 300 live births after 22 weeks of amenorrhea, drawn at random from University Hospitals in Dijon, Paris and Nancy. The variables were chosen based on the Europeristat Project's core and recommended indicators, as well as those of the French National Perinatal survey conducted in 2010. The information gathered blindly from the medical files was compared with the PMSI data positive predictive value (PPV) and the sensitivity was used to assess data quality. RESULTS Data on maternal age, parity and mode of delivery as well as the rates of premature births were superimposable for the two sources. The PPV for epidural injection was 96.2% and 94.3% for perineal tears. Overall, maternal morbidity was underdocumented in the PMSI, so the PPV was 100.0% for pre-existing diabetes, 88.9% for gestational diabetes and 100.0% for high blood pressure with a rate of 9.0% in PMSI and 6.3% in the medical files. The PPV for bleeding during labor was 89.5%. CONCLUSION To conclude, PMSI data are apparently becoming more and more reliable for two reasons: on one hand, the importance of these data for budgetary promotion in hospitals; on the other, the increasing use of this information for statistical and epidemiological purposes.

Abstract
OBJECTIVE The objective was to describe the prevalence of venous thromboembolism, pulmonary embolism, and deep vein thrombosis among hospitalized patients and the percentages of those occurring during the hospital stays. METHODS French DRG gave now the opportunity to investigate the frequency of venous thromboembolism occurring during the hospital stay. Statistics are issued from the national PMSI MCO databases encoded using the CIM10. Since 2010-2011 it is possible to differentiate the reason for hospital admission from the pathologies which secondly occurred. Any stay with the ICD-10 codes selected was considered as a hospital-occurred thrombosis unless it was the principal diagnosis of the first medical unit summary. To eliminate outpatient consultations or in day care, stays of <48 h were excluded. RESULTS The results pertain to the 78,838,983 hospitalizations in France from 2005 to 2011 and on the 18,683,603 hospital stays in 2010-2011. The incidence of hospital stays came to 860,343 (1.09%) for venous thromboembolism, with 428,261 (0.543%) for deep vein thrombosis without pulmonary embolism and 432,082 (0.548%) for pulmonary embolism. It corresponds to an incidence of 189 per 100,000 inhabitants. Out of 100 hospital stays involving venous thromboembolism, for 40.3% venous thromboembolism was the cause of hospitalization whereas 59.7% can be considered to have occurred during hospital stay. These distributions are of 25.6 and 74.4% for deep vein thrombosis, respectively, 53.8 and 46.2% for pulmonary embolism. CONCLUSION The high proportion of hospital-occurred venous thromboembolism is an alarming situation that should question the quality of prevention and/or its effectiveness.

Abstract
BACKGROUND Cancer registries are a reliable source of data to estimate national cancer incidence rates, but they are not always available in all regions. This study assessed the value of medical information systems (PMSI) to identify incident cases of colorectal cancer METHODS Two algorithms were elaborated to identify these incident cases in the PMSI database. The first algorithm was based on diagnosis and medical procedure codes and the second algorithm was based exclusively on diagnoses and the absence of diagnoses over the last five years. The results obtained for two departments were compared with those derived from two cancer registries, constituting the reference data. We then elaborated two multivariate logistic regression models to correct the national number of incident cases estimated by the algorithm adopted after evaluation of the results. RESULTS The first algorithm provided results that were very close to those derived from the regional registries (646 vs 645 cases) with a good sensitivity and positive predictive value of 75%. The second algorithm overestimated the incidence by about 50% with a positive predictive value of 60% and was therefore not adopted for the national estimation. By applying the first algorithm to the national PMSI MCO database (medicine, surgery, obstetrics), and after modelling, the estimated incidence differed by only 2.34% compared to that observed by all 14 registries. The national estimation of cancer incidence was 39,122 [37,020; 41,224] cases for 2005, which is consistent with the figure published by the Francim national registry network (37,413). CONCLUSION This study demonstrates the value of PMSI data for estimation of national incidence rates for certain cancers in the absence of cancer registries. However, raw data must be corrected and can be achieved by the method proposed here.

Abstract
Vaccine safety studies are increasingly conducted by using administrative health databases and self-controlled case series designs that are based on cases only. Often, several criteria are available to define the cases, which may yield different positive predictive values, as well as different sensitivities, and therefore different numbers of selected cases. The question then arises as to which is the best case definition. This article proposes new methodology to guide this choice based on the bias of the relative incidence and the power of the test. We apply this methodology in a validation study of 4 nested algorithms for identifying febrile convulsions from the administrative databases of 10 French hospitals. We used a sample of 695 children aged 1 month to 3 years who were hospitalized in 2008-2009 with at least 1 diagnosis code of febrile convulsions. The positive predictive values of the algorithms ranged from 81% to 98%, and their sensitivities were estimated to be 47%-99% in data from 1 large hospital. When applying our proposed methods, the algorithm we selected used a restricted diagnosis code and position on the discharge abstract. These criteria, which resulted in the selection of 502 cases with a positive predictive value of 95%, provided the best compromise between high power and low relative bias.
