[Comparison of mortality of lung cancer resections in France to other European countries]. / Comparaison de la mortalité des résections pulmonaires en France aux autres pays Européens.

BACKGROUND: France is characterized by the dispersion of its technical surgical platforms, and it seemed interesting for us to obtain information on quality of care compared to other European countries, which often have different organizations and practices. The objective of the study was to compare the 30-day mortality of patients operated on for bronchial cancer in France with that of other European countries. METHOD: We conducted a literature review on practices in different European countries. The terms used for the selection were: lung cancer surgery, 30-day mortality in different hospitals in European countries. RESULTS: We selected 9 articles corresponding to 9 European countries. The correlation coefficient between the number of lung resections per year and the population of the country was 0.967. The linear regression model between number of annual lung resections and population showed that except for Great Britain, most of the countries were close to the linear regression line. Germany and France had a mortality rate of 2.887% and 2.937% respectively, whereas the average is 2.13%. Following sensitivity analysis, the mortality rates for Germany and France remained higher than the average. CONCLUSION: France is among the European countries with the highest postoperative mortality rates. These results should induce surgical teams to adopt quality-of-care measures focusing on outcome analysis.

Prolonged impact of the COVID-19 pandemic on self-harm hospitalizations in France: A nationwide retrospective observational study.

BACKGROUND: The first wave of the COVID-19 pandemic in France was associated with a reduced number of hospitalizations for self-harm, with the exception of older people. The on-going pandemic may have both sustained and delayed effects. METHODS: Data were extracted from the French national hospital database (PMSI), a nationwide exhaustive database. The number of self-harm hospitalizations (ICD-10 codes X60-84) between September 1, 2020 and August 31, 2021 (N = 85,679) was compared to 2019 (N = 88,782) using Poisson regression models. RESULTS: There was a decrease in the total number of self-harm hospitalizations during the studied period versus 2019 (-3.5%; Relative Risk [RR] [95% Confidence Intervals] = 0.97 [0.96-0.97]; p < 0.0001). However, sex and age effects were identified. While adults aged 30-59-years-old showed a decrease (monthly decreases: -12.6 to -15.0%), we found an increase in adolescent girls (+27.7%, RR = 1.28 [1.25-1.31]; p < 0.0001), notably since January 2021. Moreover, the numbers were similar to 2019 in adolescent boys, in youths aged 20-29 years, and in people aged 70 and more. Hospitalizations in intensive care units decreased (-6.7%, RR = 0.93 [0.91-0.96]; p < 0.0001) and deaths at hospital following self-harm remained stable (+0.6%, Hazard Ratio = 0.99 [0.91-1.08], p = 0.79). CONCLUSIONS: During this second stage, the number of self-harm hospitalizations remained at a lower level than in the prepandemic period. However, significant variations over time, age, and sex were observed. Young people (notably adolescent girls) appear to have particularly suffered from the persistence of the pandemic, while older people did not show any decrease since the beginning. Vigilance and continuing prevention are warranted.

Self-harm hospitalization following bariatric surgery in adolescents and young adults.

BACKGROUND: While bariatric surgery has demonstrated physical and psychological benefits, a risk of suicide and non-fatal self-harm has also been shown. The aim of this study was to compared the rate of hospitalization for self-harm during a three-year observational follow-up period between adolescents/young adults who underwent bariatric surgery in France in 2013-2014 and two control groups. METHODS: All individuals aged 12-25 years old who underwent bariatric surgery in France between January 1st, 2013, and December 31st, 2014, were identified with a validated algorithm from the French national hospital database, and compared to a healthy sample of the general population matched for age and gender. Information relative to hospitalizations, including for self-harm (ICD-10 codes X60-84), were extracted i) between 2008 and the surgery, and ii) for a three-year follow-up period. A second unmatched control group with obesity but no bariatric surgery was also identified. Survival analyses with adjustments for confounding variables were used. RESULTS: In 2013-2014, 1984 youths had bariatric surgery in France. During follow-up, 1.5% were hospitalized for self-harm vs. 0.3% for controls (p < 0.0001). After adjustment, subsequent hospitalization for self-harm was associated with bariatric surgery (HR 3.64, 95% CI 1.70-7.81), prior psychiatric disorders (HR 7.76, 95% CI 3.76-16.01), and prior self-harm (HR 4.43, 95% CI 1.75-11.24). When compared to non-operated youths with obesity, bariatric surgery was not associated with self-harm while prior mental disorders and self-harm were. Mortality reached 0.3% after surgery. CONCLUSIONS: Bariatric surgery is associated with an increased risk of self-harm, mainly in relation to preexisting psychological conditions. Vigilance and appropriate care are thus warranted in vulnerable individuals.

[Readmissions after lung resection in France: The PMSI database]. / Les réadmissions après résection pulmonaire en France : la base de données du PMSI.

BACKGROUND: Readmission within 30 days is an indicator of the quality of care, because it often reflects post-discharge care that is not optimal. The objective of this work is to measure over time on the one hand the readmission rate and on the other hand the number of hospitals with a standardized readmission rate beyond the national average. METHOD: All patients with major pulmonary resection for lung cancer in France were extracted from the PMSI national database. Readmission within 30 days was defined as any new hospitalization either in the same hospital or in another establishment. RESULTS: From January 1, 2005 to December 31, 2018, 110,603 patients were included. The 30-day all-cause readmissions rate was 24.9% (n=27,540). Patients after pneumonectomy had a readmission rate of 37% (n=4918) and 23% after lobectomy (n=2684) (P<0.0001). For the first period, we counted 10 hospitals with a standardized readmissions rate above the 99.8 limit and 10 hospitals above the 95% limit. For the second period, 8 hospitals had a standardized readmission rate above the 99.8% limit and 11 hospitals above the 95% limit. For the third period, 7 hospitals had a standardized readmission rate above the 99.8% limit and 6 hospitals above the 95% limit. CONCLUSION: Readmissions to hospital 30 days after major lung resection for cancer in France declined little during these three periods. Measures to prevent readmissions should be introduced.

Early exposure of pregnant women to non-steroidal anti-inflammatory drugs delivered outside hospitals and preterm birth risk: nationwide cohort study.

OBJECTIVE: To assess the risk of preterm birth associated with nonsteroidal anti-inflammatory drugs (NSAIDs), focusing on early exposure in the period from conception to 22 weeks of gestation (WG). DESIGN: National population-based retrospective cohort study. SETTING: The French National Health Insurance Database that includes hospital discharge data and health claims data. POPULATION: Singleton pregnancies (2012-2014) with a live birth occurring after 22WG from women between 15 and 45 years old and insured the year before the first day of gestation and during pregnancy were included. We excluded pregnancies for which anti-inflammatory medications were dispensed after 22WG. METHODS: The association between exposure and risk of preterm birth was evaluated with GEE models, adjusting on a large number of covariables, socio-demographic variables, maternal comorbidities, prescription drugs and pregnancy complications. MAIN OUTCOME MEASURES: Prematurity, defined as a birth that occurred before 37WG. RESULTS: Among our 1 598 330 singleton pregnancies, early exposure to non-selective NSAIDs was associated with a significantly increased risk of preterm birth, regardless of the severity of prematurity: adjusted odds ratio (aOR) = 1.76 (95% CI 1.54-2.00) for extreme prematurity (95% CI 22-27WG), 1.28 (95% CI 1.17-1.40) for moderate prematurity (28-31WG) and 1.08 (95% CI 1.05-1.11) for late prematurity (32-36WG), with non-overlapping confidence intervals. We identified five NSAIDs for which the risk of premature birth was significantly increased: ketoprofen, flurbiprofen, nabumetone, etodolac and indomethacin: for the latter, aOR = 1.92 (95% CI 1.37-2.70) with aOR = 9.33 (95% CI 3.75-23.22) for extreme prematurity. CONCLUSION: Overall, non-selective NSAID use (delivered outside hospitals) during the first 22WG was found to be associated with an increased risk of prematurity. However, the association differs among NSAIDs. TWEETABLE ABSTRACT: French study for which early exposure to non-selective NSAIDs was associated with increased risk of prematurity.

Will applications on smartphones allow a generalization of telemedicine?

BACKGROUND: Telemedicine is one of the healthcare sectors that has developed the most in recent years. Currently, telemedicine is mostly used for patients who have difficulty attending medical consultations because of where they live (teleconsultation) or for specialist referrals when no specialist of a given discipline is locally available (telexpertise). However, the use of specific equipment (with dedicated cameras, screens, and computers) and the need for institutional infrastructure made the deployment and use of these systems expensive and rigid. Although many telemedicine systems have been tested, most have not generally gone beyond local projects. Our hypothesis is that the use of smartphones will allow health care providers to overcome some of the limitations that we have exposed, thus allowing the generalization of telemedicine. MAIN BODY: This paper addresses the problem of telemedicine applications, the market of which is growing fast. Their development may completely transform the organization of healthcare systems, change the way patients are managed and revolutionize prevention. This new organization should facilitate the lives of both patients and doctors. In this paper, we examine why telemedicine has failed for years to take its rightful place in many European healthcare systems although there was a real need. By developing the example of France, this article analyses the reasons most commonly put forth: the administrative and legal difficulties, and the lack of funding. We argue that the real reason telemedicine struggled to find its place was because the technology was not close enough to the patient. CONCLUSION: Finally, we explain how the development of smartphones and their current ubiquitousness should allow the generalization of telemedicine in France and on a global scale.

Recurrence and mortality 1 year after hospital admission for non-fatal self-harm: a nationwide population-based study.

AIMS: A large number of people present each day at hospitals for non-fatal deliberate self-harm (DSH). Examination of the short-term risk of non-fatal recurrence and mortality at the national level is of major importance for both individual medical decision-making and global organisation of care. METHODS: Following the almost exhaustive linkage (96%) of two national registries in France covering 45 million inhabitants (i.e. 70% of the whole population), information about hospitalisation for DSH in 2008-2009 and vital status at 1 year was obtained. Individuals who died during the index hospital stay were excluded from analyses. RESULTS: Over 2 years, 136,451 individuals were hospitalised in medicine or surgery for DSH. The sample comprised 62.8% women, median age 38 in both genders, with two peaks at 16 and 44 years in women, and one peak at 37 years in men. The method used for DSH was drug overdose in 82.1% of cases. Admission to an intensive care unit occurred in 12.9%. Following index hospitalisation, 71.3% returned home and 23.7% were transferred to a psychiatric inpatient care unit. DSH recurrence during the following year occurred in 12.4% of the sample, within the first 6 months in 75.2%, and only once in 74.6%. At 1 year, 2.6% of the sample had died. The overall standardised mortality ratio was 7.5 but reached more than 20 in young adults. The causes were natural causes (35.7%), suicide (34.4%), unspecified cause (17.5%) and accident (12.4%). Most (62.9%) deaths by suicide occurred within the first 6 months following index DSH. Violent means (i.e. not drug overdose) were used in 70% of suicide cases. Concordance between means used for index DSH and for suicide was low (30% overall), except for drug overdose. Main suicide risk factors were older age, being male, use of a violent means at index DSH, index admission to an intensive care unit, a transfer to another medical department or to a psychiatric inpatient unit, and recurrence of DSH. However, these factors had low positive predictive values individually (below 2%). CONCLUSIONS: Non-fatal DSH represent frequent events with a significant risk of short-term recurrence and death from various causes. The first 6 months following hospital discharge appear to be a critical period. Specific short-term aftercare programs targeting all people with a DSH episode have to be developed, along other suicide prevention strategies.

[Evaluation of surgical practice in the treatment of lung cancer in France from the PMSI national database]. / Évaluation de la pratique chirurgicale dans le traitement du cancer bronchique en France à partir de la base nationale du PMSI.

BACKGROUND: In recent years, improving the quality of care has been a concern for health professionals in France, through the certification of institutions, accreditation and continuous professional development. Evaluation of these different measures has rarely been carried out. The objective of the study was to evaluate the quality of surgical management of lung cancer in different regions using hospital mortality as an indicator. METHOD: From the national database of the Program of Medical Information Systems (PMSI), data on all patients who had undergone surgery for lung cancer were extracted as well as the characteristics of the centers. The main outcome criterion was hospital mortality. Logistic models allowed an estimation of the risk standardized mortality rate for each center. RESULTS: From January 1, 2015 to December 31, 2015, 10,675 patients underwent surgery for lung cancer in 158 French centers. The hospital mortality rate was 3.43% (n=366). Thirty-nine facilities (25%) performed fewer than 15 pulmonary resections. The minimum activity volume was a single pulmonary resection during the year and the maximum was 300 interventions with a coefficient of variation estimated at 147%. Hospital mortality ranged from 0 % to 50% depending on the entries with a coefficient of variation of 112%. For some regions, it is possible to count up to 5 centers per million inhabitants (Languedoc-Roussillon) or 4 centers per million inhabitants (Limousin, Pays-de-Loire). The majority of regions had 3 centers per million inhabitants. Eleven regions have no centers with a standardized mortality rate below 3%. Five regions (Languedoc-Roussillon, Pays-de-Loire, Aquitaine, Brittany and Provence Alpes Côte d'Azur) have at least two centers with a risk standardized rate of mortality above 4%. Among the academic centers, 20% have a risk standardized mortality rate of less than 3%. Among the centers with a risk standardized rate of mortality<3%, 20% performed more than 39 pulmonary resections, 7% between 39 and 15 procedures and 0% for centers with<15 interventions. CONCLUSION: This work confirms that hospital volume is one of the components of quality of care. The number of centers should be adapted to the actual needs of the population in order to enable patients to access effective services.

Postpartum hemorrhage with transfusion: Trends, near misses, risk factors and management at the scale of a perinatal network.

OBJECTIVES: To analyze temporal trends and management of postpartum hemorrhage (PPH) with transfusion and its related maternal near-miss (MNM) cases between 2006 and 2014 and to study risk factors. MATERIAL AND METHODS: This retrospective cohort study from two prospective databases included 156,047 women giving birth in all the maternity hospitals of Burgundy. We analyzed temporal trends and the distribution of PPH with transfusion, the circumstances of transfer of patients between hospitals and factors associated with PPH with transfusion. PPH with massive blood transfusion and/or non-medical treatment was defined as MNM. Statistical analysis included Chi2 tests and logistic regression for multivariate analysis. RESULTS: The overall rate of PPH with transfusion was 7.3‰ and globally increased during the study period whereas the MNM rate did not. MNM represented 37% of patients with PPH with transfusion and 71% of transferred patients, but surgical treatments were performed before transfer. Factors associated with PPH with transfusion were maternal age>35 years (odds ratio [OR]=1.3), prematurity (OR=5.0), cesarean section (OR=4.8), placenta previa (OR=22.0), twin pregnancy (OR=6.6), HELLP syndrome (OR=17.9) and severe small-for-gestational-age infants (OR=2.0). The first four were also associated with MNM. CONCLUSION: MNM cases of PPH rates were steady in Burgundy while rates of PPH with transfusion increased moderately.

[The REDSIAM network]. / Le réseau REDSIAM (Réseau données Sniiram) ­ Spécial REDSIAM.

The French national health database (SNIIRAM) proved to be very useful for epidemiology, health economics, evaluation, surveillance or public health. However, it is a complex database requiring important resources and expertise for being used. The REDSIAM network has been set up for promoting the collaboration of teams working on the Sniiram. The main aim of REDSIAM is to develop and validate methods for analyzing the Sniiram database for research, surveillance, evaluation and public health purposes by sharing the knowledge and experience of specialized teams in the fields of diseases identification from the Sniiram data. The work conducted within the network is devoted to the development and the validation of algorithms using Sniiram data for identifying specific diseases. The REDSIAM governance includes the Steering Committee composed of the main organizations in charge of producing and using the Sniiram data, the Bureau and the Technical Committee. The network is organized in thematic working groups focused on specific pathological domains, and a charter defines the rules for participation in the network, the functioning of the thematic working groups, the rules for publishing and making available algorithms. The articles in this special issue of the journal present the first results of some of the thematic working groups.

[Study of algorithms to identify schizophrenia in the SNIIRAM database conducted by the REDSIAM network]. / Étude des algorithmes de repérage de la schizophrénie dans le Sniiram par le réseau REDSIAM.

BACKGROUND: The aim of the REDSIAM network is to foster communication between users of French medico-administrative databases and to validate and promote analysis methods suitable for the data. Within this network, the working group "Mental and behavioral disorders" took an interest in algorithms to identify adult schizophrenia in the SNIIRAM database and inventoried identification criteria for patients with schizophrenia in these databases. METHODS: The methodology was based on interviews with nine experts in schizophrenia concerning the procedures they use to identify patients with schizophrenia disorders in databases. The interviews were based on a questionnaire and conducted by telephone. RESULTS: The synthesis of the interviews showed that the SNIIRAM contains various tables which allow coders to identify patients suffering from schizophrenia: chronic disease status, drugs and hospitalizations. Taken separately, these criteria were not sufficient to recognize patients with schizophrenia, an algorithm should be based on all of them. Apparently, only one-third of people living with schizophrenia benefit from the longstanding disease status. Not all patients are hospitalized, and coding for diagnoses at the hospitalization, notably for short stays in medicine, surgery or obstetrics departments, is not exhaustive. As for treatment with antipsychotics, it is not specific enough as such treatments are also prescribed to patients with bipolar disorders, or even other disorders. It seems appropriate to combine these complementary criteria, while keeping in mind out-patient care (every year 80,000 patients are seen exclusively in an outpatient setting), even if these data are difficult to link with other information. Finally, the experts made three propositions for selection algorithms of patients with schizophrenia. CONCLUSION: Patients with schizophrenia can be relatively accurately identified using SNIIRAM data. Different combinations of the selected criteria must be used depending on the objectives and they must be related to an appropriate length of time.

Early screening for type 2 diabetes following gestational diabetes mellitus in France: hardly any impact of the 2010 guidelines.

AIMS: Women who had gestational diabetes mellitus (GDM) have a high risk of type 2 diabetes mellitus (T2DM) in the years following pregnancy. Most follow-up screening studies have been conducted in limited geographical areas leading to large variability in the results. The aim of our investigation was to measure how the publication of guidelines affected early screening for T2DM after a pregnancy with GDM during the period 2007-2013, in France. METHODS: We conducted a retrospective cohort study in a representative sample of 1/97th of the French population using data from the "National Health Insurance Inter-Regime Information System," which collects individual hospital and non-hospital data for healthcare consumption. RESULTS: The sample included 49,080 women who gave birth in 2007-2013. In the following 3 months, only 18.49% of women with GDM had an oral glucose tolerance test or a blood glucose test in 2007. This rate had not significantly increased in 2013 (p = 0.18). The proportion of women with GDM who had the recommended glycemic follow-up at 3 months (20.30 vs. 21.58%, p = 0.19) and 6 months (32.48 vs. 37.16%, p = 0.08) was not significantly different before the guidelines (2008-2009) and after the guidelines (2012-2013). At 12 months, the difference was significant (46.77 vs. 54.05%, p = 0.009). CONCLUSION: Postpartum screening has improved only slightly since the guidelines and remains largely insufficient, with less than 25% of women with GDM screened in the first 3 months. In the first year after delivery, less than 60% of women were screened for T2DM.

Association between Pseudomonas aeruginosa positive water samples and healthcare-associated cases: nine-year study at one university hospital.

OBJECTIVE: To study the association between the results of water samples and Pseudomonas aeruginosa healthcare-associated cases in a French university hospital. METHODS: Generalized Estimating Equations were used on complete case and imputed datasets. The spatial unit was the building and the time unit was the quarter. RESULTS: For the period 2004-2013, 2932 water samples were studied; 17% were positive for P. aeruginosa. A higher incidence of P. aeruginosa cases was associated with a higher proportion of positive water samples (P=0.056 in complete case analysis and P=0.031 with the imputed dataset). The association was no longer observed when haematology and intensive care units were excluded, but was significant in analyses of data concerning intensive care units alone (P<0.001). CONCLUSION: This study suggests that water outlet contamination in hospitals can lead to an increase in healthcare-associated P. aeruginosa cases in wards dealing with susceptible patients, but does not play a significant role in other wards.
