[Evaluation of the effectiveness of the new perioperative model to recover surgical activity during the COVID-19 pandemic]. / Evaluación de la efectividad del nuevo modelo perioperatorio para recuperar la actividad quirúrgica durante la pandemia de COVID-19.

INTRODUCTION: The first wave of the COVID-19 pandemic caused the cancellation of elective interventions. After the improvement of the epidemiological situation, new models of care were applied in hospitals to restart the programmed surgical activity. The aim was to evaluate the effectiveness of the organizational model established to recover surgical activity during the transition period of the COVID-19 pandemic. METHODS: Retrospective observational study comparing patients who underwent schedule surgery from September 1 until October 31, 2020, study group, with a control group of the same period of time corresponding to the year 2019 at the General Hospital from the Vall d'Hebron University Hospital. RESULTS: The total population included 1,825 patients, 888 in the study group and 937 in the control group. Global surgical activity decreased 6.43% during the study period compared to the same period in 2019, with a 25.5% decrease in cancer surgeries. Seven patients became infected with SARS-CoV-2 during their hospital stay. In hospital mortality was 0.9% in the study group compared to 0.7% in control group (p=0.8). The survival rate in cancer patients at 90 days was lower in the study group (95.7% vs 98.7%; p=0.02). CONCLUSIONS: The change in the management model during the transition period of the COVID-19 pandemic allowed the recovery of programmed surgical activity to levels similar to those existing prior to the pandemic with a greater impact on cancer surgery.

Prevalencia preoperatoria de portadores asintomáticos de COVID-19 en hospitales de Cataluña durante la primera ola tras el reinicio de la actividad quirúrgica / Pre-operative prevalence of asymptomatic carriers of COVID-19 in hospitals in Catalonia during the first wave after the resumption of surgical activity

Introducción La pandemia producida por COVID-19 ocasionó la cancelación de los procedimientos quirúrgicos no esenciales en marzo de 2020. Con el reinicio de la actividad quirúrgica, los pacientes que se sometían a una cirugía fueron uno de los primeros grupos poblacionales a los que se realizó test PCR de forma sistemática. El objetivo de este estudio fue determinar la prevalencia de portadores asintomáticos de SARS-CoV-2 tras el reinicio de la actividad quirúrgica no esencial. Métodos Estudio observacional multicéntrico retrospectivo de los pacientes programados para cirugía o que se sometieron a cirugía urgente en Cataluña entre el 20 de abril y el 31 de mayo de 2020. Se revisaron los resultados microbiológicos de los test PCR preoperatorios, las historias clínicas y se realizó una encuesta epidemiológica a los pacientes con PCR positiva para SARS-CoV-2. Resultados Un total de 10.838 pacientes programados para una intervención quirúrgica o a los que se realizó una cirugía urgente fueron sometidos a cribado para COVID-19. Ciento dieciocho pacientes (1,09%) fueron positivos para SARS-CoV-2 en las 72h previas a la cirugía. La prevalencia de portadores asintomáticos fue del 0,7% (IC95%: 0,6-0,9%). La primera semana del estudio presentó la prevalencia más alta de portadores asintomáticos [1,9% (IC95%: 1,1-3,2%)]. Conclusiones Los bajos niveles de portadores asintomáticos de infección por COVID-19 obtenidos en la población quirúrgica de los hospitales de Cataluña tras el reinicio de la actividad quirúrgica muestran que la mayoría de pacientes se pudieron someter a procedimientos quirúrgicos sin los riesgos de las complicaciones asociadas al COVID-19 en el periodo perioperatorio (AU)

Introduction The COVID-19 pandemic led to the cancellation of non-essential surgical procedures in March 2020. With the resumption of surgical activity, patients undergoing surgery were one of the first population groups to be systematically tested for PCR. The aim of this study was to determine the prevalence of asymptomatic SARS-CoV-2 carriers after the resumption of non-essential surgical activity. Methods Retrospective multicenter observational study of patients scheduled for surgery or undergoing emergency surgery in Catalonia between 20 April and 31 May 2020. The microbiological results of preoperative PCR tests and clinical records were reviewed, and an epidemiological survey was conducted on patients with positive PCR for SARS-CoV-2. Results A total of 10,838 patients scheduled for surgery or who underwent emergency surgery were screened for COVID-19. One hundred and eighteen patients (1.09%) were positive for SARS-CoV-2 in the 72hours prior to surgery. The prevalence of asymptomatic carriers was 0.7% (95%CI: 0.6% - 0.9%). The first week of the study presented the highest prevalence of asymptomatic carriers [1.9% (95%CI: 1.1%-3.2%)]. Conclusions The low levels of asymptomatic carriers of COVID-19 infection obtained in the surgical population of hospitals in Catalonia after the resumption of surgical activity, shows that most patients were able to undergo surgical procedures without the risks of COVID-19 associated complications in the perioperative period (AU)
