Item Decline in subarachnoid haemorrhage volumes associated with the first wave of the COVID-19 pandemic(2021) Nguyen, Thanh N.; Haussen, Diogo C.; Qureshi, Muhammad M.; Yamagami, Hiroshi; Fujinaka, Toshiyuki; Mansour, Ossama Y.; Abdalkader, Mohamad; Frankel, Michael; Qiu, Zhongming; Taylor, Allan; Lylyk, Pedro; Eker, Omer F.; Mechtouff, Laura; Piotin, Michel; Oliveira Lima, Fabricio; Mont'Alverne, Francisco; Izzath, Wazim; Sakai, Nobuyuki; Mohammaden, Mahmoud; Al-Bayati, Alhamza R.; Renieri, Leonardo; Mangiafico, Salvatore; Ozretic, David; Chalumeau, Vanessa; Ahmad, Saima; Rashid, Umair; Irteza Hussain, Syed; John, Seby; Griffin, Emma; Thornton, John; Fiorot, Jose Antonio; Rivera, Rodrigo; Hammami, Nadia; Cervantes-Arslanian, Anna M.; Hammami, Nadia; Cervantes-Arslanian, Anna M.; Dasenbrock, Anna M.; Le Vu, Huynh; Nguyen, Viet Quy; Hetts, Steven; Bourcier, Romain; Guile, Romain; Walker, Melanie; Sharma, Malveeka; Frei, Don; Jabbour, Pascal; Herial, Nabeel; Al-Mufti, Fawaz; Ozdemir, Atilla Ozcan; Aykac, Ozlem; Gandhi, Dheeraj; Chugh, Chandril; Matouk, CharlesBackground: During the COVID-19 pandemic, decreased volumes of stroke admissions and mechanical thrombectomy were reported. The study's objective was to examine whether subarachnoid haemorrhage (SAH) hospitalisations and ruptured aneurysm coiling interventions demonstrated similar declines. Methods: We conducted a cross-sectional, retrospective, observational study across 6 continents, 37 countries and 140 comprehensive stroke centres. Patients with the diagnosis of SAH, aneurysmal SAH, ruptured aneurysm coiling interventions and COVID-19 were identified by prospective aneurysm databases or by International Classification of Diseases, 10th Revision, codes. The 3-month cumulative volume, monthly volumes for SAH hospitalisations and ruptured aneurysm coiling procedures were compared for the period before (1 year and immediately before) and during the pandemic, defined as 1 March-31 May 2020. The prior 1-year control period (1 March-31 May 2019) was obtained to account for seasonal variation. Findings: There was a significant decline in SAH hospitalisations, with 2044 admissions in the 3 months immediately before and 1585 admissions during the pandemic, representing a relative decline of 22.5% (95% CI -24.3% to -20.7%, p<0.0001). Embolisation of ruptured aneurysms declined with 1170-1035 procedures, respectively, representing an 11.5% (95%CI -13.5% to -9.8%, p=0.002) relative drop. Subgroup analysis was noted for aneurysmal SAH hospitalisation decline from 834 to 626 hospitalisations, a 24.9% relative decline (95% CI -28.0% to -22.1%, p<0.0001). A relative increase in ruptured aneurysm coiling was noted in low coiling volume hospitals of 41.1% (95% CI 32.3% to 50.6%, p=0.008) despite a decrease in SAH admissions in this tertile. Interpretation: There was a relative decrease in the volume of SAH hospitalisations, aneurysmal SAH hospitalisations and ruptured aneurysm embolisations during the COVID-19 pandemic. These findings in SAH are consistent with a decrease in other emergencies, such as stroke and myocardial infarction.Publication Did COVID-19 impact stroke services? A multicenter study(2022) Shokri, Hossam; El Nahas, Nevine; El Basiony, Ahmed; Nguyen, Thanh; Abdalkader, Mohamad; Klein, Piers; Lavados, Pablo; Olavarría, Verónica; Amaya, Pablo; Llanos, Natalia; Brola, Waldemar; Michał, Lipowski; Melgarejo, Donoband; Cardozo, Analia; Caballero, Cesar; Pedrozo, Fatima; Rahman, Aminur; Hokmabadi, Elyar; Jalili, Javad; Farhoudi, Mehdi; Aref, Hany; Roushdy, TamerBackground: It has been reported that acute stroke services were compromised during COVID-19 due to various pandemic-related issues. We aimed to investigate these changes by recruiting centers from different countries. Methods: Eight countries participated in this cross-sectional, observational, retrospective study by providing data from their stroke data base. We compared 1 year before to 1 year during COVID-19 as regards onset to door (OTD), door to needle (DTN), door to groin (DTG), duration of hospital stay, National Institute of Health Stroke Scale (NIHSS) at baseline, 24 h, and at discharge as well as modified Rankin score (mRS) on discharge and at 3 months follow-up. Results: During the pandemic year, there was a reduction in the number of patients, median age was significantly lower, admission NIHSS was higher, hemorrhagic stroke increased, and OTD and DTG showed no difference, while DTN time was longer, rtPA administration was decreased, thrombectomy was more frequent, and hospital stay was shorter. mRS was less favorable on discharge and at 3 months. Conclusion: COVID-19 showed variable effects on stroke services. Some were negatively impacted as the number of patients presenting to hospitals, DTN time, and stroke outcome, while others were marginally affected as the type of management.Item Global Impact of COVID-19 on Stroke Care and IV Thrombolysis(2021) Nogueira, Raúl G.; Qureshi, Muhammad M.; Abdalkader, Mohamad; Martins, Sheila Ouriques; Yamagami, Hiroshi; Mansour, Ossama Yassin; Qiu, Zhongming; Sathya, Anvitha; Czlonkowska, Anna; Tsivgoulis, Georgios; Aguiar de Sousa, Diana; Demeestere, Jelle; Mikulik, Robert; Vanacker, Peter; Siegler, James E.; Kõrv, Janika; Biller, Jose; Liang, Conrad W.; Sangha, Navdeep S.; Zha, Alicia M.; Czap, Alexandra L.; Holmstedt, Christine Anne; Turan, Tanya N.; Ntaios, George; Malhotra, Konark; Tayal, Ashis; Loochtan, Aaron; Ranta, Annamarei; Mistry, Eva A.; Alexandrov, Anne W.; Huang, David Y.; Yaghi, Shadi; Raz, Eytan; Sheth, Sunil A.; Mohammaden, Mahmoud H.; Frankel, Michael; Bila Lamou, Eric Guemekane; Aref, Hany M.; Elbassiouny, Ahmed; Hassan, Farouk; Menecie, Tarek; Mustafa, Wessam; Shokr, Hossam M.; Roushdy, Tamer; Sarfo, Fred S.; Alabi, Tolulope Oyetunde; Arabambi, Babawale; Nwazor, Ernest O.; Sunmonu, Taofiki Ajao; Wahab, Kolawole; Yaria, Joseph; Hussein Mohammed, Haytham; Adebayo, Philip B.; Riahi, Anis D.; Sassi, Samia Ben; Navia, Víctor; Olavarría, VerónicaObjective To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods. Methods We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases. Results There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95% confidence interval [CI] −11.7 to −11.3, p < 0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95% CI −13.8 to −12.7, p < 0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95% CI −13.7 to −10.3, p = 0.001). Recovery of stroke hospitalization volume (9.5%, 95% CI 9.2–9.8, p < 0.0001) was noted over the 2 later (May, June) vs the 2 earlier (March, April) pandemic months. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was noted in 3.3% (1,722/52,026) of all stroke admissions. Conclusions The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID-19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months.
