Missed training, collateral damage from COVID 19?

BACKGROUND: during the COVID-19 pandemic a total lockdown was enforced all over Italy starting on March 9th. This resulted in the shrinking of economic activities. In addition, all formal occupational security-training courses were halted, among them the 81/08 law lectures and Basic Life Support-Defibrillation (BLS-D) laymen training courses. The aim of the study was to evaluate the impact of the pandemic on BLS-D laymen training courses in the Lombardy region. METHODS: BLS-D training courses records for the Lombardy region were analysed. The analysis was conducted from 2016 to 2020 as part of the Hippo project. RESULTS: between 2017 and 2019 BLS-D trained laymen kept increasing, moving from 53,500 trained individuals up to 74,700. In 2020 a stark reduction was observed with only 22,160 individuals trained. Formal courses were not halted completely during 2020. Still, in the months available for training, the number of individuals enrolled showed a sharp 50% reduction. CONCLUSIONS: laymen training courses for emergency management are a fundamental component of primary prevention practice. The 81/08 and 158/12 Italian laws have decreed this practice mandatory on the workplace. Following the enforcement of the lockdown and the subsequent interruption of emergency management courses, efforts will be necessary to re-establish and guarantee the high quality training of the pre-pandemic period.

Cardiopulmonary resuscitation missed by bystanders: Collateral damage of coronavirus disease 2019.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic changed the time-dependent cardiac arrest network. This study aims to understand whether the rescue standards of cardiopulmonary resuscitation (CPR) and out-of-hospital cardiac arrest (OHCA) were handled differently during pandemic compared to the previous year. METHODS: Data for the years 2019 and 2020 were provided by the records of the Lombardy office of the Regional Agency for Emergency and Urgency. We analysed where the cardiac arrest occurred, when CPR started and whether the bystanders used public access to defibrillation (PAD). RESULTS: During 2020, there was a reduction in CPRs performed by bystanders (odds ratio [OR] = 0.936 [95% confidence interval (CI95% ) 0.882-0.993], p = .029) and in the return of spontaneous circulation (ROSC) (OR = 0.621 [CI95% 0.563-0.685], p < .0001), while there was no significant reduction in the use of PAD. Analysing only March, the period of the first wave in Lombardy, the comparison shows a reduction in bystanders CPRs (OR = 0.727 [CI95% 0.602-0.877], p = .0008), use of PAD (OR = 0.441 [CI95% 0.272-0.716], p = .0009) and in ROSC (OR = 0.179 [CI95% 0.124-0.257], p < .0001). These phenomena could be influenced by the different settings in which the OHCAs occurred; in fact, those that occurred in public places with a mandatory PAD were strongly reduced (OR = 0.49 [CI95% , 0.44-0.55], p < .0001). CONCLUSIONS: COVID-19 had a profound impact on the time-dependant OHCA network. During the first pandemic wave, CPR and PAD used by bystanders decreased. The different contexts in which OHCAs occurred may partially explain these differences.

OHCA survey in Lombardy: comparison between years 2014 and 2019 (pre COVID-19).

BACKGROUND AND AIM: The incidence of Out of Hospital Cardiac Arrest (OHCA) is estimated at 1/1000 persons/year. In the pre-Covid-19 era world, OHCA survival rate in Europe was 7-6%. The main objective is to analyze OHCA survival in the Lombardy region by highlighting the factors related to both the victims' characteristics and the chain of survival. METHODS: All OHCAs were grouped into four pre-established periods in 2019 (14-23 January; 15-24 April; 15-24 July; 14-23 October). Following the Utstein method, we selected witnessed OHCAs with presumed cardiac etiology. The outcome of each case was collected in four moments in time: Return of spontaneous circulation (ROSC), Emergency Department (ED), 24 hours and 30 days. The neurological outcome 30 days after OHCA was also investigated and stratified with the Cerebral Performance Category Score (CPC). RESULTS: We selected 456 cases of OHCA with witnessed cardiac etiology. ROSC was achieved in 121 cases (26.5%), survival in the Emergency Departments in 110 patients (24.1%), after 24 hours in 86 (18.86%) and after 30 days in 72 (15.8%). Male sex was shown to improve OHCA survival. A shockable presentation rhythm, Cardiopulmonary Resuscitation (CPR) performed by bystanders and the activation of Public Access Defibrillation (PAD) positively influenced OHCA outcome. CONCLUSIONS: Males are more predisposed to incur an OHCA event than females, but they have greater chances of survival. Factors most related to survival are: shockable rhythm, bystanders CPR and the activation of a PAD. (www.actabiomedica.it).

The Lombardy Emergency Medical System Faced with COVID-19: The Impact of Out-of-Hospital Outbreak.

OBJECTIVE: The Lombardy region was among the areas most affected by COVID-19 infection worldwide; the Lombardy Emergency Medical System (EMS) responded immediately to this emergency. We analyzed several critical aspects to understand what occurred in that region. METHODS: This retrospective study compares the events managed by the dispatch center and the characteristics of the patients transported to the hospital -age, sex, SpO2, deaths- managed by the EMS in Brescia and Bergamo provinces between March-April 2020 and March-April 2019. Ambulances' waiting time at the hospitals before discharging patients and the patients' severity at emergency department admission were also analyzed. RESULTS: EMS managed 37,340 events in March-April 2020, +51.5% versus 2019. "Breathing" or "Infective" events reported to the dispatch center increased more than ten-fold (OR 25.1, p < 0.0001) in March 2020 and two-fold in April 2020 compared to 2019 (OR 3, p < 0.0001). Deaths increased +246% (OR 1.7, p < 0.0001), and patients not transported to hospital +481% (OR 2.9, p < 0.0001) in March 2020 compared to 2019. In some hospitals, ambulances waited more than one hour before discharging the patients, and the emergency departments doubled the admission of critically ill patients. Transported patients for "Breathing" or "Infective" events were primarily males (OR 1.5, p < 0.0001). The patients had lower SpO2 in 2020 than in 2019 and they were younger. CONCLUSIONS: The Lombardy region experienced an unexpected outbreak in an extremely short timeframe and in a limited area. The EMS coped with this pandemic, covering an extremely higher number of requests, with a ten-fold increase in the number of events managed.
