In-Hospital Delays for Acute Stroke Treatment Delivery During the COVID-19 Pandemic.

BACKGROUND: We investigated the impact of regionally imposed social and healthcare restrictions due to coronavirus disease 2019 (COVID-19) to the time metrics in the management of acute ischemic stroke patients admitted at the regional stroke referral site for Central South Ontario, Canada. METHODS: We compared relevant time metrics between patients with acute ischemic stroke receiving intravenous tissue plasminogen activator (tPA) and/or endovascular thrombectomy (EVT) before and after the declared restrictions and state of emergency imposed in our region (March 17, 2020). RESULTS: We identified a significant increase in the median door-to-CT times for patients receiving intravenous tPA (19 min, interquartile range (IQR): 14-27 min vs. 13 min, IQR: 9-17 min, p = 0.008) and/or EVT (20 min, IQR: 15-33 min vs. 11 min, IQR: 5-20 min, p = 0.035) after the start of social and healthcare restrictions in our region compared to the previous 12 months. For patients receiving intravenous tPA treatment, we also found a significant increase (p = 0.005) in the median door-to-needle time (61 min, IQR: 46-72 min vs. 37 min, IQR: 30-50 min). No delays in the time from symptom onset to hospital presentation were uncovered for patients receiving tPA and/or endovascular reperfusion treatments in the first 1.5 months after the establishment of regional and institutional restrictions due to the COVID-19 pandemic. CONCLUSION: We detected an increase in our institutional time to treatment metrics for acute ischemic stroke patients receiving tPA and/or endovascular reperfusion therapies, related to delays from hospital presentation to the acquisition of cranial CT imaging for both tPA- and EVT-treated patients, and an added delay to treatment with tPA.

Délais dans le traitement en milieu hospitalier des AVC aigus dans le contexte de la pandémie de COVID-19. CONTEXTE: Nous nous sommes penchés, dans le contexte de la pandémie de COVID-19, sur l'impact de restrictions régionales imposées dans le domaine social et dans les soins de santé sur les délais de prise en charge de patients victimes d'un AVC aigu. À noter que ces patients ont été admis dans un centre régional de traitement des AVC situé dans le centre-ouest de l'Ontario (Canada). MÉTHODES: Nous avons comparé entre eux les délais de prise en charge de patients ayant bénéficié d'activateurs tissulaires du plasminogène par intraveineuse (tPA) et/ou d'une procédure de thrombectomie endovasculaire (TE) avant et après la mise sur pied de restrictions et l'imposition d'un état d'urgence sanitaire dans notre région (17 mars 2020). RÉSULTATS: Après la mise sur pied de ces restrictions, nous avons identifié, par rapport aux 12 mois précédent, une augmentation notable des délais médians entre l'arrivée à l'hôpital et un examen de tomodensitométrie dans le cas de patients bénéficiant de tPA (19 minutes, EI : 14­27 minutes contre 13 minutes, EI : 9­17 minutes ; p = 0,008) et/ou d'une procédure de TE (20 minutes, EI : 15­33 minutes contre 11 minutes, EI : 5­20 minutes ; p = 0,035). Pour ce qui est des patients bénéficiant de tPA, nous avons également observé une augmentation importante (p = 0,005) des délais médians entre leur arrivée à l'hôpital et l'injection d'un traitement (61 minutes, EI : 46­72 minutes contre 37 minutes, EI : 30­50 minutes). Enfin, dans le premier mois et demi suivant la mise sur pied des restrictions régionales et institutionnelles attribuables à la pandémie de COVID-19, aucun délai supplémentaire entre l'apparition des premiers symptômes d'un AVC et l'arrivée à l'hôpital n'a été remarqué pour des patients bénéficiant de tPA et/ou d'une procédure de TE. CONCLUSION: En somme, nous avons détecté une augmentation de nos délais de traitement dans le cas de patients victimes d'un AVC aigu ayant bénéficié de tPA et/ou d'une procédure de TE. Cela peut être attribué à une augmentation des délais de présentation à l'hôpital mais aussi à des délais dans l'obtention d'images de tomodensitométrie pour des patients traités avec des tPA et une procédure de TE, sans compter des délais accrus pour bénéficier d'un traitement de tPA.

An Evaluation of the Family Informal Caregiver Stroke Self-Management Program.

BACKGROUND: Caregivers are often unprepared and overwhelmed with the responsibilities of providing care to stroke survivors, which can lead to negative physical and psychological effects. PURPOSE: To evaluate the impact of the Family Informal Caregiver Stroke Self-Management (FICSS) program on burden and life changes resulting from providing care among family caregivers of stroke survivors. METHODS: A prospective pre-test and post-test design using quantitative and qualitative data was used to evaluate the program with a convenience sample of 42 caregivers. The four-module facilitated program consisted of small group-guided discussion. Quantitative evaluations were completed at baseline, 2 weeks and 6 months (post-intervention), and qualitative data were collected at 2 weeks and 6 months. Life changes and burden were measured using the Bakas Caregiving Outcome Scale (BCOS) and the Oberst Caregiving Burden Scale (OCBS), respectively. RESULTS: The BCOS scores increased consistently over time, showing significant differences at 6 months compared with 2 weeks (mean difference: 5.29, 95% confidence interval [CI]: 0.30-10.28, p=0.04) and baseline (mean difference: 7.58, 95% CI: 2.92-12.23, p=0.001). The OCBS time scores decreased consistently over time, showing a significant difference at 6 months compared with baseline (mean difference: -5.20, 95% CI: -0.96 to -9.44, p=0.02). The OCBS difficulty scores fluctuated over time, resulting in no overall difference from baseline to 6 months. Qualitative themes were consistent with the positive quantitative findings. CONCLUSION: Study results suggest that the FICSS program may result in reduced caregiver burden and improved life changes resulting from providing care.

Does the NRS Capture Changes in Communication during Inpatient Stroke Rehabilitation?

BACKGROUND: In Ontario, the National Rehabilitation Reporting System (NRS) is mandated for use as a measurement of change for stroke patients after admission to and discharge from rehabilitation. The NRS includes the functional independence measure (FIM) and supplementary measurement items developed by the Canadian Institute for Health Information (CIHI). Uncertainty exists regarding the efficacy of the NRS as the sole measure of outcome for communication in stroke rehabilitation patients. The use of additional speech-language pathology outcome measurement tools for this population has therefore been suggested. OBJECTIVES: This study sought to establish whether the FIM and CIHI communication items capture quantifiable gains during stroke rehabilitation and therefore whether additional measures are needed to assess outcomes. METHODS: A retrospective analysis was completed of 1252 complete data records of stroke patients discharged from inpatient rehabilitation at Hamilton Health Sciences between 2006 and 2011. RESULTS AND IMPACT: Statistically significant improvements were observed in all total matched FIM scores (M = 72.68 to M = 96.39, P < .001) and for each expression (M = 4.61 to M = 5.35, P < .001) and comprehension (M = 4.69 to M = 5.33, P < .001) subscale. The most severely affected group demonstrated the greatest gains. These findings were independent of stroke severity. Additional outcome measurement tools for communication are therefore not required to assess outcomes in rehabilitation of stroke patients, although additional research is necessary to evaluate the clinical significance of the improvements that are observed using existing measurements of change.

Tissue plasminogen activator overdose in acute ischemic stroke patients linked to poorer functional outcomes.

BACKGROUND: The dose of intravenous tissue plasminogen activator (tPA) administered in acute ischemic stroke patients is calculated using the patient's weight (0.9 mg/kg). Patients are rarely weighed before treatment in actual practice, although overestimating patient weights leads to higher doses of tPA, which may adversely influence outcome. METHODS: We investigated the weight used to calculate the dose of tPA compared to the actual measured weight in consecutive acute ischemic stroke patients treated over a 4-year period at our center. The rate of intracranial hemorrhage (ICH), discharge modified Rankin Scale (mRS) score, and mortality at 3 months were compared between groups, according to accuracy of the dose of tPA. RESULTS: We found that 140 of 164 (85%) acute ischemic stroke patients treated with tPA had a measured weight documented in the chart after treatment. Of these, 13 patients received ≥1.0 mg/kg and 16 patients received ≤0.8 mg/kg, based on a comparison of the weight used for the tPA dose calculation and the subsequent measured weight. Four of 13 (31%) patients treated with ≥1.0 mg/kg of tPA developed ICH. Patients who inadvertently received higher doses of tPA had a lower likelihood of a good functional outcome at discharge (mRS score 0-2; 0% v 34%; P = .009). No difference in 3-month mortality was observed, although patients who were not weighed in hospital had a threefold increase in discharge mortality (21% v 7%; P = .019). CONCLUSIONS: Our findings provide support for the practice of accurately weighing all acute ischemic stroke patients before thrombolysis.

Pilot evaluation of the family informal caregiver stroke self-management program.

BACKGROUND: Due to the abrupt onset of a stroke, caregivers are often unprepared for the role, have extensive needs and are at risk for negative outcomes. Interventions facilitating development of coping and problem solving skills are shown to decrease the negative effects of caregiving. The Family Informal Caregiver Stroke Self-Management (FICSS) program was developed to address the unmet needs of family caregivers of stroke survivors. OBJECTIVE: To evaluate the content, format and resource materials of the FICSS program with 10-12 family caregivers of stroke survivors within Central South Ontario. METHODS: The FICSS program is a four-module education and support series of facilitated small group discussions. Topics included: balancing changing roles, managing behaviour changes, sexuality/intimacy, and community linkages. Each module was evaluated weekly and by focus group one month after the program. RESULTS: Eleven family caregivers of stroke survivors with three years of mean caregiving experience participated. Caregivers valued the opportunity to share experiences and learn from others who understood what they were going through. Recommendations were made to improve the program topic areas, content and flow. CONCLUSIONS: The pilot evaluation of the program validated the content of the FICSS program and indicated recommendations for improvement.

Using a quality improvement process to create measurable improvement in care delivery for acute stroke.

The introduction of thrombolytic therapy has revolutionized the management of acute ischemic stroke, and it has now been conclusively established that tissue plasminogen activator (t-PA) given within 4.5 hours of stroke onset both limits irreversible ischemic neuronal damage by establishing reperfusion of the penumbra and improves outcomes for patients who have undergone stroke. As a regional stroke centre, Hamilton Health Services (HHS) seeks to ensure it meets guidelines and readiness criteria in acute stroke care. This article discusses how HHS developed and used a quality improvement process to ensure all patients receive thrombosis therapy within 60 minutes of arrival at hospital.
