National Cross-Sectional Epidemiological Analysis of the Impact of Pandemic COVID-19 on Vascular Procedures in Public Health System: 521,069 Procedures Over 4 Years

BACKGROUND

During the COVID-19 pandemic, there was a dramatic increase in healthcare demand. Resources were redirected to care patients with COVID-19. Therefore, surgical treatments were affected, including those of vascular diseases. There are no studies evaluating the whole impact of the COVID-19 pandemic, considering all types of vascular procedures, both elective and urgent, in a large country. The aim of the present study was to analyze the impact on all types of vascular procedures performed in Brazilian public hospitals during the COVID-19 pandemic.

METHODS

Cross-sectional population-based analysis of publicly available data referring to vascular procedures. Surgeries 2 years before the pandemic onset (2018-2019) and 2 years during pandemic (2020-2021) were included.

RESULTS

We observed a total of 521,069 procedures. Decrease was observed in elective abdominal aortic aneurysm repairs both open surgery (P = 0.001) and endovascular surgery (P < 0.001), emergency open abdominal repairs (P = 0.005), elective thoracic aortic aneurysm repairs (P = 0.007), elective open peripheral aneurysm repairs (P = 0.038), carotid endarterectomies (P < 0.001) and angioplasties (P = 0.001), open revascularizations for peripheral arterial disease (P < 0.001), surgical treatment of chronic venous disease (P < 0.001) and sympathectomies for hyperhidrosis (P < 0.001). However, there was an increase of lower limb amputations (P = 0.027) and vena cava filter placements (P = 0.005). There was a reduction of almost US$17 million in financial investments.

CONCLUSIONS

The reorganization of health systems led to a significant reduction in vascular procedures and decrease in financial investments. On the other hand, there was a significant increase in the number of lower limb amputations and vena cava filter placements.

Reduced Vascular Practice and Increased Cardiovascular Mortality for COVID-19-Negative Patients

BACKGROUND

The aim of our study was to compare COVID-19- and not-COVID-19-related mortality rates in two Italian regions during the pandemic period when the same isolation rules and therapeutic approaches were introduced for all hospitals in Italy. Risk factors for not-COVID-19-related deaths during the pandemic were analyzed; we tried to assess a possible correlation between reducing hospital visits and "deferrable" vascular operations and the increased cardiovascular mortality not related to COVID-19 infection.

METHODS

We analyzed COVID-19- and not-COVID-19-related mortality rates in two Italian regions in the period January 2020-January 2021. We compared mortality rates during the pandemic period with those of the previous five years. We tried to determine the factors involved in increased mortality rates during the pandemic period.

RESULTS

Despite the same isolation rules for people and the same therapeutic approaches for hospitals, mortality rates did not increase in the region Lazio, where the pandemic was not severe. In the region Lombardy, the mortality rate was doubled in comparison with the previous years, and 50% of the increase was related to not-COVID-19 deaths.

CONCLUSIONS

The increase in mortality rates for not-COVID-19-related deaths in the region Lombardy was connected to the generalized turmoil in the acute phase of an overwhelming pandemic, including diffuse stress, inadequate communications, reluctance to ask for medical help unless symptoms were severe, and unexpected inadequate number of health workers, hospital beds, and intensive care unit beds. Reduced hospital visits may have had a fundamental role.

A scoping review on the changes in vascular surgical practice during the early phases of the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has had a profound effect on the delivery of vascular surgery to patients around the world. In order to conserve resources and reduce the risk of COVID-19 infection, many institutions have postponed or cancelled surgical procedures. In this scoping review, we aim to review current literature and recapitulate the significant changes in elective and emergency vascular surgery during the COVID-19 pandemic. We conducted this scoping review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. We included all articles that had reported the effects of the COVID-19 pandemic on elective or emergency vascular surgery. A total of 28 articles were included in this scoping review. We identified eight distinct themes that were relevant to our study topic. We report global, regional, and local data on vascular surgical cases. We also discuss the adoption of vascular surgery triage systems, emergence of global collaborative vascular surgery research groups, increased use of endovascular techniques and locoregional anesthesia, delayed presentation of vascular surgery conditions, and poorer outcomes of patients with chronic limb threatening ischemia. This scoping review provides a snapshot of the impact of the COVID-19 pandemic on elective and emergency vascular surgery.

The impact of COVID-19 pandemic on vascular registries and clinical trials

Quality improvement programs and clinical trial research experienced disruption due to the coronavirus disease 2019 (COVID-19) pandemic. Vascular registries showed an immediate impact with significant declines in second-quarter vascular procedure volumes witnessed across Europe and the United States. To better understand the magnitude and impact of the pandemic, organizations and study groups sent grass roots surveys to vascular specialists for needs assessment. Several vascular registries responded quickly by insertion of COVID-19 variables into their data collection forms. More than 80% of clinical trials have been reported delayed or not started due to factors that included loss of enrollment from patient concerns or mandated institutional shutdowns, weighing the risk of trial participation on patient safety. Preliminary data of patients undergoing vascular surgery with active COVID-19 infection show inferior outcomes (morbidity) and increased mortality. Disease-specific vascular surgery study collaboratives about COVID-19 were created for the desire to study the disease in a more focused manner than possible through registry outcomes. This review describes the pandemic effect on multiple VASCUNET registries including Germany (GermanVasc), Sweden (SwedVasc), United Kingdom (UK National Vascular Registry), Australia and New Zealand (bi-national Australasian Vascular Audit), as well as the United States (Society for Vascular Surgery Vascular Quality Initiative). We will highlight the continued collaboration of VASCUNET with the Vascular Quality Initiative in the International Consortium of Vascular Registries as part of the Medical Device Epidemiology Network coordinated registry network. Vascular registries must remain flexible and responsive to new and future real-world problems affecting vascular patients.
