RESUMEN

INTRODUCTION: Ultrasound is a feasible and reproducible method for measuring right diaphragmatic excursion (RDE) in ED patients with acute dyspnea (AD). In AD patients, the correlation between the RDE value and the need for mechanical ventilation (MV) is not known. MATERIALS: This was a bicentric, observational prospective study. The RDE measurement was done at admission. The need for MV was defined by the use of MV within 4 h of AD management. An optimal threshold for RDE was determined as the value that minimized the incorrect predictions of the use of MV in the first 4 h as the highest Youden index. RESULTS: We analyzed 102 patients (79 [70; 86] years), 38 (37%) of whom had been ventilated. The RDE value was 1.7 cm [1.4; 2.0] and 2.2 cm [1.8; 2.6] in the ventilated and non-ventilated groups, respectively (p = 0.06). The AUC was 0.68 95% CI [0.57; 0.80]. With a threshold of 2 cm, the sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) were 76% [60%; 89%], 59% [46%; 71%], 81% [67%; 91%], and 53% [39%; 66%], respectively. In the non-COPD patients, the RDE values were 1.5 cm [1.2; 1.9] and 2.2 cm [1.8; 2.6] (p < 0.01) in the ventilated and not-ventilated groups, respectively. The AUC was 0.77 95% CI [0.64; 0.90]. With a threshold of 2.18 cm, the sensitivity, specificity, NPV, and PPV were 91% [71%; 99%], 51% [36%; 66%], 92% [75%; 99%], and 54% [38%; 69%], respectively. CONCLUSION: The RDE values at ED admission were unable to define a prognostic threshold value associated with subsequent MV need in the AD patients. In non-COPD patients, the NPV was 92%.

RESUMEN

Purpose: Few data are available on complications occurring during inter-hospital transfer from a primary stroke center (PSC) to a comprehensive stroke center (CSC) for endovascular treatment (EVT) after large vessel occlusion (LVO). Therefore, we prospectively studied data from consecutive patients transferred from our PSC to the next CSC during 4 years to determine the incidence and risk factors of complications during transfer. Methods: This observational, single-center study included consecutive patients transferred from January 1, 2015 to December 31, 2018. During inter-hospital transfer, all medical incidents were systematically recorded. A new complete clinical examination was performed on arrival at the CSC. Results: Among the 253 patients transferred to the CSC during the study period, 68 (26.9%) had one or more complications. In 11 patients (4.3%) these were life-threatening and required emergency intervention by a physician. Baseline characteristics were not different between patients with and without complications, except for the LVO location. Specifically, basilar artery (BA) occlusion was strongly associated with complications during the transport (p < 0.0005). Conclusion: Complications occurred in 26.9% of patients during transfer. Only BA occlusion could predict complication during transfer. Future studies should identify variables to help stratifying patients at high and low risk of complications during transportation.

RESUMEN

INTRODUCTION: The current guidelines advocate the implementation of stroke networks to organize endovascular treatment (ET) for patients with acute ischemic stroke due to large vessel occlusion (LVO) after transfer from a Primary Stroke Centre (PSC) to a Comprehensive Stroke Centre (CSC). In France and in many other countries around the world, these transfers are carried out by a physician-led mobile medical team. However, with the recent broadening of ET indications, their availability is becoming more and more critical. Here, we retrospectively analysed data of patients transferred from a PSC to a CSC for potential ET to identify predictive factors of major complications (MC) at departure and during transport that absolutely require the presence of a physician during interhospital transfer. METHODS: This observational, single-centre study included patients with evidence of intracranial LVO transferred for ET from Perpignan to a 156 km-distant CSC between January 1, 2015 and -December 31, 2018. We compared 2 groups: MC group (patients who required emergency intervention by the medical team due to life-threatening complications, including need of mechanical ventilation at departure) and non-MC group (all other patients who experienced no or only minor complications that could be managed by the emergency paramedics alone). RESULTS: Among the 253 patients who were transferred to the CSC, 185 (73.1%) had no complication, 57 (22.6%) minor complications, and 11 (4.3%) had MC. In multivariate analysis, MC was associated with basilar artery (BA) occlusion (p < 0.0001), initial National Institute of Health Stroke Scale (NIHSS) score >22 (p < 0.005), and history of atrial fibrillation (p < 0.04). Among the 168 patients treated with intravenous thrombolysis (IVT), only 1 patient (0.6%) had MC due to an IVT-related adverse event during transfer. CONCLUSIONS: Physician-led inter-hospital transports are warranted for patients with BA occlusion, initial NIHSS score >22, or history of atrial fibrillation. For the other patients, transfer without a physician may be considered, even if treated with IVT.

RESUMEN

INTRODUCTION: Little is known about the effectiveness of endovascular treatment (EVT) in patients with acute ischemic stroke (AIS) due to large vessel occlusion (LVO) admitted to a primary stroke center (PSC). The aim of this study was to assess EVT effectiveness after transfer from a PSC to a distant (156 km apart; 1.5 hour by car) comprehensive stroke center (CSC), and to discuss perspectives to improve access to EVT, if indicated. PATIENTS AND METHOD: Analysis of the data collected in a 6-year prospective registry of patients admitted to a PSC for AIS due to LVO and selected for transfer to a distant CSC for EVT. The rate of transfer, futile transfer, EVT, reperfusion (thrombolysis in cerebral infarction score ≥2b-3), and relevant time measures were determined. RESULTS: Among the 529 patients eligible, 278 (52.6%) were transferred and 153 received EVT (55% of transferred patients) followed by reperfusion in 115 (overall reperfusion rate: 21.7%). Median times (interquartile range) were: 90 minutes (76-110) for PSC-door-in to PSC-door-out, 88 minutes (65-104) for PSC-door-out to CSC-door-in, 262 minutes (239-316) for PSC-imaging to reperfusion, and 393 minutes (332-454) for symptom onset to reperfusion. At 3 months, rates of favorable outcome (modified Rankin Scale 0-2) were not significantly different between patients eligible for EVT (42.4%), transferred patients (49.1%) and patients who underwent EVT (34.1%). DISCUSSION AND CONCLUSIONS: Our study suggests that transfer to a distant CSC is associated with reduced access to early EVT. These results argue in favor of on-site EVT at high volume PSCs that are distant from the CSC.

RESUMEN

BACKGROUND AND PURPOSE: Inter-hospital transfer for mechanical thrombectomy (MT) might result in the transfer of patients who finally will not undergo MT (ie, futile transfers [FT]). This study evaluated FT frequency in a primary stroke center (PSC) in a semi-rural area and at 156 km from the comprehensive stroke center (CSC). METHODOLOGY: Retrospective analysis of data collected in a 6-year prospective registry concerning patients admitted to our PSC within 4.5 hours of acute ischemic stroke (AIS) symptom onset, with MR angiography indicating the presence of large vessel occlusion (LVO) without large cerebral infarction (DWI-ASPECT ≥5), and selected for transfer to the CSC to undergo MT. Futile transfer rate and reasons were determined, and the relevant time measures recorded. RESULTS: Among the 529 patients screened for MT, 278 (52.6%) were transferred to the CSC. Futile transfer rate was 45% (n=125/278) and the three main reasons for FT were: clinical improvement and reperfusion on MRI on arrival at the CSC (58.4% of FT); clinical worsening and/or infarct growth (16.8%); and longer than expected inter-hospital transfer time (11.2%). Predictive factors of FT due to clinical improvement/reperfusion on MRI could not be identified. Baseline higher NIHSS (21 vs 17; P=0.01) and lower DWI-ASPECT score (5 vs 7; P=0.001) were associated with FT due to clinical worsening/infarct growth on MRI. CONCLUSIONS: In our setting, 45% of transfers for MT were futile. None of the baseline factors could predict FT, but the initial symptom severity was associated with FT caused byclinical worsening/infarct growth.

RESUMEN

OBJECTIVE: The purpose of this study was to demonstrate that the median door-to-needle (DTN) time for intravenous tissue plasminogen activator (tPA) treatment can be reduced to 45 min in a primary stroke centre with MRI-based screening for acute ischaemic stroke (AIS). METHODS: From February 2015 to February 2017, the stroke unit of Perpignan general hospital, France, implemented a quality-improvement (QI) process. During this period, patients who received tPA within 4.5 h after AIS onset were included in the QI cohort. Their clinical characteristics and timing metrics were compared each semester and also with those of 135 consecutive patients with AIS treated by tPA during the 1-year pre-QI period (pre-QI cohort). RESULTS: In the QI cohort, 274 patients (92.5%) underwent MRI screening. While the demographic and baseline characteristics were not significantly different between cohorts, the median DTN time was significantly lower in the QI than in the pre-QI cohort (52 vs. 84 min; p < 0.00001). Within the QI cohort, the median DTN time for each semester decreased from 65 to 44 min (p < 0.00001) and the proportion of treated patients with a DTN time ≤45 min increased from 25 to 58.9% (p < 0.0001). Overall, DTN time improvement was associated with a better outcome at 3 months (patients with a modified Rankin Scale score between 0 and 2: 61.8% in the QI vs. 39.3% in the pre-QI cohort; p < 0.0001). CONCLUSIONS: A QI process can reduce the DTN within 45 min with MRI as a screening tool.

RESUMEN

Background No comprehensive study exists about mechanical thrombectomy accessibility for patients admitted to a primary stroke center without onsite interventional neuroradiology service. Aims To evaluate mechanical thrombectomy accessibility within 6 h after transfer from a primary stroke center to a distant (156 km apart; 1.5 h by car) comprehensive stroke center. Methods Analysis of data collected in a three-year prospective registry on patients admitted to a primary stroke center within 4.5 h after symptom onset and selected for transfer to a comprehensive stroke center for mechanical thrombectomy. Eligible patients had confirmed proximal arterial occlusion and no large cerebral infarction on MRI images (DWI-ASPECTS ≥ 5). The rate of transfer, transfer without mechanical thrombectomy, mechanical thrombectomy, reperfusion (TICI score ≥ 2b-3), and the main relevant time measures were determined. Results Among the 385 patients selected for intravenous thrombolysis and/or potential mechanical thrombectomy, 211 were considered as transferrable for mechanical thrombectomy. The rate of transfer was 56.4% (n = 119/211), transfer without mechanical thrombectomy 56.3% (n = 67/119), mechanical thrombectomy 24.6% (n = 52/211), and reperfusion by MT (TICI score 2b/3) 18% (n = 38/211). The relevant median times (interquartile range) were: 130 min (62) for intravenous thrombolysis start to comprehensive stroke center door, 95 minutes (39) for primary stroke center door-out to comprehensive stroke center door-in, 191 min (44) for intravenous thrombolysis start to mechanical thrombectomy puncture, 354 min (107) for symptom onset to mechanical thrombectomy puncture and 417 min (124) for symptom onset to recanalization. Conclusions Our study suggests that transfer to a distant comprehensive stroke center is associated with reduced access to early mechanical thrombectomy in patients with acute ischemic stroke and large artery occlusion. These results could be translated to other high volume distant primary stroke center.

RESUMEN

UNLABELLED: STUDY OBJECTIVE AND BACKGROUND: Arterial puncture for blood gas analysis is a frequent procedure and could be difficult in the emergency setting. The aim of the study was to compare ultrasonographically guided arterial radial puncture vs conventional sampling. MATERIALS AND METHODS: This is a prospective, randomized study. The inclusion criteria are all patients needing arterial blood gas at admission in the emergency unit. The exclusion criteria are the following: Hallen test positive, local sepsis, local trauma, known sever local arteriopathy, refusal of consent by the patient, participation in another study, and cardiac arrest. Patients were randomized into 2 groups: radial arterial puncture obtained through an ultrasonographically guided technique (group 1) or radial arterial puncture by conventional method (group 2). The main objective is the number of attempts after enrollment. The secondary objectives are time to success, patient satisfaction and pain, and physician satisfaction. Immediate complications were collected. Groups were compared with nonparametric analysis. RESULTS: The data were usable for 72 of 74 patients included. Lung disease (acute exacerbation of chronic obstructive pulmonary disease and pneumonia) at 45% (n = 32) and suspicion of pulmonary embolism in 31% (n = 22) were the most common reasons. Demographics data were comparable in the 2 groups. In group 1, the number of attempts significantly increased (2.35 [1-3] vs 1.66 [1-2] [P = .017]), and the sample was 2.4 times longer (132 seconds [50-200] vs 55 [20-65] [P < .01] by standard method). There was no significant difference in terms of pain (visual analog scale [VAS], 3.6 [2-5] for both groups [P = .743]), patient satisfaction (VAS, 7.2 [5-9] vs 6.8 [5-9] [P = .494]), and physician satisfaction (VAS, 6.0 [3.5-8] vs 6.9 [5-9] [P = .233]). No immediate complications were found in the 2 groups. CONCLUSION: Ultrasonographically guided arterial puncture increases the number and duration of implementations. This technique, however, does not alter the patient's pain, the number of immediate complications, or patient and physician satisfaction.

RESUMEN

Hospitals implement electronic medical record systems (EMRSs) that are intended to support medical and nursing staff in their daily work. Evolution toward more computerization seems inescapable. Nevertheless, this evolution introduced new problems of organization. This before-and-after observational study evaluated the door-to-first-medical-contact (FMC) times before and after the introduction of EMRS. A satisfaction questionnaire, administered after the "after" period, measured clinicians' satisfaction concerning computerization in routine clinical use. The following 5 questions were asked: Do you spare time in your note taking with EMRS? Do you spare time in the medical care that you provide to the patients with EMRS? Does EMRS improve the quality of medical care for your patients? Are you satisfied with the EMRS implementation? Would you prefer a return to handwritten records? Results showed an increase in door-to-FMC time induced by EMRS and a lower triage capacity. In the satisfaction questionnaire, clinicians reported minimal satisfaction but refused to return to handwritten records. The increase in door-to-FMC time may be explained by the improved quantity/quality of data and by the many interruptions due to the software. Medical reorganization was requested after the installation of the EMRS.

RESUMEN

OBJECTIVE: To evaluate the knowledge of emergency resuscitation procedures of general practitioners in Bouches-du-Rhône, the Gard, Hérault and Vaucluse. METHODS: We sent 7239 self-assessment mail questionnaires to general practitioners. The responses were analyzed to determine the factors associated with lack of mastery of emergency resuscitation procedures; physicians who reported they could not perform these procedures were compared with the others. RESULTS: In all, 1561 responses were analyzed (response rate=22%); 52% reported they had to perform emergency resuscitation procedures at least once a year, but 30% stated they had not mastered them. After multivariate analysis with logistic regression, the factors associated with lack of mastery of these procedures (or with mastery, for the variables with odds ratios <1) were age (reference 25-35 years, 36-45 years: odds ratio [OR]=1.94, 95% confidence interval (95% CI) [1.11-3.40]; 46-55 years, OR=2.93 [1.70-5.05]; age>55 years, OR=3.71 [2.07-6.62]), women (OR=1.39 [1.05-1.82]), clerkship or course in resuscitation and emergency medicine (second cycle clerkships, OR=0.75 [0.57-0.97]; third cycle internship, OR=0.30 [0.22-0.42]; course at another time, OR=0.43 [0.28-0.66]), performance of emergency resuscitation procedures in daily practice (reference: no procedure performed; at least one a year: OR=0.37 [0.29-0.49]; at least one every three months, OR=0.15 [0.08-0.25]), failure to use health records (reference: does not use records; users OR=0.70 [0.54-0.90]). CONCLUSION: More consistent continuing medical education up seems necessary to meet the need for continuity of care, especially in the greatest emergencies.
