Stroke management during the coronavirus disease 2019 (COVID-19) pandemic: experience from three regions of the north east of Italy (Veneto, Friuli-Venezia-Giulia, Trentino-Alto-Adige)

Global stroke statistics 2023: Availability of reperfusion services around the world

BACKGROUND

Disparities in the availability of reperfusion services for acute ischemic stroke are considerable globally and require urgent attention. Contemporary data on the availability of reperfusion services in different countries are used to provide the necessary evidence to prioritize where access to acute stroke treatment is needed.

AIMS

To provide a snapshot of published literature on the provision of reperfusion services globally, including when facilitated by telemedicine or mobile stroke unit services.

METHODS

We searched PubMed to identify original articles, published up to January 2023 for the most recent, representative, and relevant patient-level data for each country. Keywords included thrombolysis, endovascular thrombectomy and telemedicine. We also screened reference lists of review articles, citation history of articles, and the gray literature. The information is provided as a narrative summary.

RESULTS

Of 11,222 potentially eligible articles retrieved, 148 were included for review following de-duplications and full-text review. Data were also obtained from national stroke clinical registry reports, Registry of Stroke Care Quality (RES-Q) and PRE-hospital Stroke Treatment Organization (PRESTO) repositories, and other national sources. Overall, we found evidence of the provision of intravenous thrombolysis services in 70 countries (63% high-income countries (HICs)) and endovascular thrombectomy services in 33 countries (68% HICs), corresponding to far less than half of the countries in the world. Recent data (from 2019 or later) were lacking for 35 of 67 countries with known year of data (52%). We found published data on 74 different stroke telemedicine programs (93% in HICs) and 14 active mobile stroke unit pre-hospital ambulance services (80% in HICs) around the world.

CONCLUSION

Despite remarkable advancements in reperfusion therapies for stroke, it is evident from available patient-level data that their availability remains unevenly distributed globally. Contemporary published data on availability of reperfusion services remain scarce, even in HICs, thereby making it difficult to reliably ascertain current gaps in the provision of this vital acute stroke treatment around the world.

The impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review

AIMS

Cardiovascular diseases (CVD) are the leading cause of death worldwide. The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems, causing delays in essential medical services, and potentially impacting CVD treatment. This study aims to estimate the impact of the pandemic on delayed CVD care in Europe by providing a systematic overview of the available evidence.

METHODS AND RESULTS

PubMed, Embase, and Web of Science were searched until mid-September 2022 for studies focused on the impact of delayed CVD care due to the pandemic in Europe among adult patients. Outcomes were changes in hospital admissions, mortality rates, delays in seeking medical help after symptom onset, delays in treatment initiation, and change in the number of treatment procedures. We included 132 studies, of which all were observational retrospective. Results were presented in five disease groups: ischaemic heart diseases (IHD), cerebrovascular accidents (CVA), cardiac arrests (CA), heart failures (HF), and others, including broader CVD groups. There were significant decreases in hospital admissions for IHD, CVA, HF and urgent and elective cardiac procedures, and significant increases for CA. Mortality rates were higher for IHD and CVA.

CONCLUSION

The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Adequate resource allocation, clear guidelines on how to handle care during health crises, reduced delays, and healthy lifestyle promotion should be implemented. The long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19 should be further evaluated.

Enteral Nutrition and Hydration in Patients with Acute Stroke: Efficacy of an Automatic Pump System for Water Administration and Flushes-A Pilot Study

BACKGROUND

Enteral nutrition is often prescribed in acute stroke to meet energy and fluid needs in patients with dysphagia. Tubes clogging represent a common complication of enteral formula delivery, requiring substitution and influencing nutrition administration. Frequent water flushes are recommended as one of the most effective procedures to prevent tube occlusion, but it might be time demanding and not consistently performed by the healthcare staff. This study aimed to assess the efficacy of an automatic flush pump, compared to a manual flush system, to prevent tubes' occlusions in acute-stroke patients, as this might affect nutrition and hydration.

METHODS

Gastrointestinal symptoms, nutrition and hydration biomarkers were also monitored to determine the different devices' safety. Sixty-two patients were included in the study and allocated to the "manual" or "automatic" flushes device.

RESULTS

The mean duration of data collection was 7 ± 2 days. Tube occlusions occurred in 22.6% of the patients in the "manual" group, whereas only one tube clogging was reported in the "automatic" group (p = 0.023). No significant differences between groups were reported for constipation and diarrhea frequency nor nutrition and hydration status. When the nurses were asked to simulate manual flush administration at the same frequency of the automatic device, they were able to meet the recommendations only 10% of the time.

CONCLUSION

This preliminary study suggests the efficacy of automatic flush systems to prevent enteral tube clogging, without affecting health status compared to standard manual flush systems.

Results of an International Questionnaire Investigating Changes in Acute Stroke Management between Before and During the COVID-19 Pandemic

Objective

The present study investigated changes in the management of acute stroke patients between before and during the coronavirus disease 2019 (COVID-19) pandemic in several countries using a questionnaire.

Methods

A questionnaire survey was conducted at 23 stroke centers in 20 countries to examine how stroke management systems have changed from 2019 (before the COVID-19 pandemic) to 2020 (during the COVID-19 pandemic).

Results

Questionnaire responses were obtained from 14 stroke centers (61%) in 14 countries. Among the surveyed stroke centers, 36% utilized full personal protective equipment (PPE) including N95 masks in all cases. After the proper application of infection precautions and screening for COVID-19, the initial imaging modality and indications for endovascular thrombectomy (ET) for ischemic stroke remained unchanged in more than 85% of the surveyed stroke centers. The transmission of COVID-19 from stroke patients to doctors or nurses was confirmed in 29% of the surveyed stroke centers, and hospital-acquired infection from patients to other patients occurred in 25%. The number of cases undergoing ET decreased by 10-70% in 50% of stroke centers during the COVID-19 pandemic. Despite successful recanalization, 50% of patients who underwent ET died, and death was mainly attributed to COVID-19-related systemic complications.

Conclusion

No significant differences were observed in stroke management or treatment strategies between before and during the COVID-19 pandemic in most stroke centers, except for COVID-19 precautions. However, the higher proportion of hospital-acquired infections and increased morbidity rate among patients despite successful recanalization due to COVID-19-related systemic complications are important findings.
