Efficacy of recanalization therapy for ischemic stroke: multicenter hospital network experience

PURPOSE

Stroke is a leading cause of long-term disability with high mortality rate in the first year after the event. In Campania, mechanical thrombectomy treatment significantly increases in the last 3 years, as well as hospitals delivering acute stroke treatments. The aim of this study is to demonstrate how a full opening of our stroke network improves stroke management and stroked patients' survival in Campania.

MATERIAL AND METHODS

In Federico II University Hospital of Naples acting as a HUB center of 7 peripheral SPOKE hospitals in regional territory, 68 patients with acute ischemic stroke were evaluated with NIHSS and m-RS clinical scores and neuroradiological ASPECT scores, from January 1 to December 31, 2021. At hospital discharge, NIHSS score and three months after m-RS score were re-assessed to evaluate the therapeutic effects.

RESULTS

Forty-two of 68 patients (63%) admitted to our hub center had ischemic acute stroke at CT evaluation; 29 patients had ASPECT score > 7 (69%), and 6 a score < 7 (14%). At admission, NIHSS score mean value was 10.75, and m-RS score mean value was 0.74. At discharge, NIHSS score mean value was 7.09. After three months, m-RS score mean value was 0.74.

DISCUSSION

The inter-company agreement between Federico II University and several peripheral hospitals allows an absolute and relative increase in endovascular mechanical thrombectomy and intravenous thrombolysis procedures, with a relative prevalence of mechanical thrombectomy. A regional implementation of the stroke multi-disciplinary care system is hardly needed to ensure the optimum treatment for the largest number of patients, improving patient's outcome.

Prevalence, clinical characteristics, resource utilization and outcome of patients with acute chest pain in the emergency department. A multicenter, prospective, observational study in north-eastern Italy

BACKGROUND

The evaluation and triage of patients with suspected myocardial ischemia in the emergency department is challenging and costly. In Italy there are no prospective data neither about the prevalence, clinical characteristics, and outcome of patients with chest pain in the emergency room, nor about the costs of their triage. Therefore, this study was undertaken to evaluate the diagnostic accuracy and costs of the actual emergency department triage modalities of patients with acute chest pain.

METHODS

We analyzed the clinical data from a multicenter, prospective study of all patients with chest pain who presented to the emergency department of three hospitals in North-Eastern Italy from April to October 1999.

RESULTS

Of 12,375 new medical admissions at the three emergency departments during the study period, 495 (prevalence 4%, mean age 62 +/- 16 years, 50% females) were for chest pain. Thirty-seven percent of the patients with chest pain were hospitalized with a suspected acute coronary syndrome, while 63% were directly discharged from the emergency department. The diagnosis of acute coronary syndrome was confirmed in 79% of hospitalized patients. Among the patients discharged directly from the emergency department 68% were immediately sent back home (69 +/- 60 min from admission) and 32% required a brief clinical observation lasting 10 +/- 6 hours and including serial electrocardiographic and myocardial injury marker assessment. The average cost of the emergency department triage was 189 +/- 237 [symbol: see text]/patient. The 1-month follow-up of the patients directly discharged from the emergency department revealed a 2.5% incidence of acute coronary syndromes (3 acute myocardial infarctions), but no deaths.

CONCLUSIONS

Data obtained from our multicenter observational study suggest that present triage modalities for patients with chest pain in the emergency department based on patient history, clinical data, electrocardiography, and myocardial injury marker assessment could be improved in terms of accuracy and efficacy. Our data provide the clinical and economical framework for the designation of trials of new accelerated critical pathways for chest pain evaluation in the emergency department.
