Comparison between local and three validated triage systems in an emergency department for 2126 children under 3 months.

AIM: Triage of patients less than 3 months old was not already studied. The aim was to evaluate Paediatric Emergency Department triage in patients less than 3 months old and newborns using a local system in comparison with three validated paediatric triage systems (Canadian Triage and Acuity Scale, Manchester Triage System and Emergency Severity Index) and to determine inter-system agreement. METHODS: All admissions of patients less than 3 months old admitted to the Emergency Department of the Saint Vincent University Hospital between April 2018 and December 2019 were included. The local triage system level was determined prospectively for comparison with retrospectively calculated triage levels of the validated systems. Hospitalisation rates were compared and inter-system agreements determined. RESULTS: Among emergency admissions, 2126 were included (55% males, mean age 45 days). Hospitalisation rate increased with priority severity as determined by all triage systems studied. Cohen's kappa showed slight agreement between the local triage system and the Canadian Triage and Acuity Scale, Emergency Severity Index and Manchester Triage System (weighted kappa = 0.133, 0.185 and 0.157 respectively). CONCLUSION: Whether prospective or retrospective triage used, the systems studied exhibited good association with hospitalisation rate for patients aged less than 3 months and newborn infants.

Long-term follow-up of survivors of a first acute coronary syndrome: Results from the French MONICA registries from 2009 to 2017.

AIM: The objectives of the study were to characterize the long-term risk of first recurrence of acute coronary syndrome (ACS) among survivors of an incident ACS, as a function of the STEMI/NSTEMI/UA diagnosis. METHODS: Men and women (aged 35-74) hospitalized between 2009 and 2016 for an incident ACS in the French MONICA registries and still alive on discharge were followed-up until December 2017. Recurrent events were defined as the first (non-fatal or fatal) ACS occurring after hospital discharge from the incident event. RESULTS: The study comprised 15,739 incident ACSs with 63,777 patient-years of follow-up. The cumulative probability [95% confidence interval] of recurrent ACS was 6.7% [6.3-7.1%] at 1 year and 18.4% [17.4-19.5%] at 9 years. The cumulative probability of fatal recurrent ACS was 1.4% [1.2-1.5%] at 1 year and 4.3% [3.6-4.9%] at 9 years. The risk of recurrence did not depend on the type of the incident ACS after adjustment for confounding factors. The most frequent forms of recurrence were NSTEMI and UA. The presence of a major complication (OR = 1.59) and an impaired left ventricular ejection fraction (LVEF) (OR > 1.26) increased the risk of recurrence. The annual 1-year recurrence rates decreased from 7.4% in 2009 to 4.0% in 2016 (p < 0.001). CONCLUSION: The recurrence rate after an incident ACS remained high in France, and the risk of recurrence did not depend on the etiology of the first event. Our results emphasize the importance of targeting patients with a major complication and/or an impaired LVEF who are at a higher risk of recurrence.

Periprocedural, early, and long-term risks of pacemaker implantation after atrioventricular nodal re-entry tachycardia ablation: a French nationwide cohort.

AIMS: Pacemaker implantation (PI) after atrioventricular nodal re-entry tachycardia (AVNRT) ablation is a dreadful complication. We aimed to assess periprocedural, early, and late risks for PI. METHODS AND RESULTS: All 27 022 patients who underwent latest AVNRT ablation in France from 2009 to 2017, were identified in the nationwide medicalization database. A control group of 305 152 patients hospitalized for arm, leg, or skin injuries with no history of AVNRT or supraventricular tachycardia were selected. After propensity score matching, both groups had mean age of 53 ± 18 years and were predominantly female (64%). During this 9-year period, 822 of 27 022 (3.0%) AVNRT patients underwent PI, with significant higher risk in propensity-matched AVNRT patients compared to propensity-matched controls [2.9% vs. 0.9%; hazard ratio 3.4 (2.9-3.9), P < 0.0001]. This excess risk was significant during all follow-up, including periprocedural (1st month), early (1-6 months), and late (>6 months) risk periods. Annualized late risk per 100 AVNRT patients was 0.2%. In comparison to controls, excess risk was 0.2% in <30-year-old AVNRT patients; 0.7% in 30-50-year-old; 1.1% in 50-70-year-old and 6.5% over 70-year-olds. Risk for PI was also significantly different according to three procedural factors: centres, experience, and ablation date, with a 30% decrease since 2015. CONCLUSION: Periprocedural, early, and late risks for PI were higher after AVNRT ablation compared to propensity-matched controls. Longer follow-up is needed as the excess risk seems to persist late after AVNRT ablation.

From Data Extraction to Analysis: Proposal of a Methodology to Optimize Hospital Data Reuse Process.

In the Lille University Hospital (North of France), data from the Anesthesia Information Management System (Diane® are linked to the Hospital Information System and stored in a dedicated data warehouse since 2010. These electronic medical records need to be reused and analyzed for observational studies. The aim of this paper is to describe the framework developed to structure the operation of that anesthesia data warehouse for research purposes. The presented framework is structured around three meetings between clinicians, computer scientists, and statisticians. The data scientist acts as a coordinator, leads meetings, and checks each milestone. Reuse of anesthesia-related electronic medical record for research purposes is only allowed through this framework. The aim of the first meeting is to decide the primary and secondary objectives of the study. The aim of the second meeting is to validate the statistical protocol. The data are extracted and the statistical analyses are performed. Finally, the results are presented, explained and discussed during the third meeting. During a 6 months period, 27 projects were included in the framework leading to 5 scientific communications. As a result, case studies with extraction and/or analysis situations are presented. This collaboration led to an empowerment process between all three actors, which increased efficiency of the workflow. Implementation of this framework will keep encouraging collaborative publication in order to provide reproducible research evidence.
