Clinician's Perception of Practice Changes for Stroke During the COVID-19 Pandemic

Background

Approach to acute cerebrovascular disease management has evolved in the past few months to accommodate the rising needs of the 2019 novel coronavirus (COVID-19) pandemic. In this study, we investigated the changes in practices and policies related to stroke care through an online survey.

Methods

A 12 question, cross-sectional survey targeting practitioners involved in acute stroke care in the US was distributed electronically through national society surveys, social media and personal communication.

Results

Respondants from 39 states completed 206 surveys with the majority (82.5%) from comprehensive stroke centers. Approximately half stated some change in transport practices with 14 (7%) reporting significant reduction in transfers. Common strategies to limit healthcare provider exposure included using personal protective equipment (PPE) for all patients (127; 63.5%) as well as limiting the number of practitioners in the room (129; 64.5%). Most respondents (81%) noted an overall decrease in stroke volume. Many (34%) felt that the outcome or care of acute stroke patients had been impacted by COVID-19. This was associated with a change in hospital transport guidelines (OR 1.325, P = 0.047, 95% CI: 1.004–1.748), change in eligibility criteria for IV-tPA or mechanical thrombectomy (MT) (OR 3.146, P = 0.052, 95% CI: 0.988–10.017), and modified admission practices for post IV-tPA or MT patients (OR 2.141, P = 0.023, 95% CI: 1.110–4.132).

Conclusion

Our study highlights a change in practices and polices related to acute stroke management in response to COVID-19 which are variable among institutions. There is also a reported reduction in stroke volume across hospitals. Amongst these changes, updates in hospital transport guidelines and practices related to IV-tPA and MT may affect the perceived care and outcome of acute stroke patients.

Risk factors for development of cerebral edema following cardiac arrest

BACKGROUND

Cerebral edema following cardiac arrest is a well-known complication of resuscitation and portends a poor outcome. We identified predictors of post-cardiac arrest cerebral edema and tested the association of cerebral edema with discharge outcome.

METHODS

We performed a retrospective chart review including patients admitted at a single center between January 2015-March 2020 following resuscitation from in-hospital and out-of-hospital cardiac arrest who had head computed tomography imaging. Our primary outcome was moderate-to-severe cerebral edema, which we defined as loss of grey-white differentiation with effacement of the basal and ambient cisterns and radiographic evidence of uncal herniation. We used logistic regression to test associations of demographic information, clinical predictors and comorbidities with moderate-severe cerebral edema.

RESULTS

We identified 727 patients who met the inclusion criteria, of whom 102 had moderate-to-severe cerebral edema. We identified six independent predictors of moderate-to-severe cerebral edema: younger age, prolonged arrest duration, pulseless electrical activity/asystole as initial rhythm, unwitnessed cardiac arrest, hyperglycemia on admission, and lower Glasgow coma score on presentation. Of patients with moderate-to-severe cerebral edema, 2% survived to discharge, 56% had withdrawal of life-sustaining therapies and 42% progressed to death by neurological criteria.

CONCLUSIONS

Our study identified several risk factors associated with the development of cerebral edema following cardiac arrest. Further studies are needed to determine the benefits of early interventions in these high-risk patients.

Development of a self-administered psychosocial cancer screening tool

Among patients with cancer, psychosocial issues and problems are common, yet they often go unnoticed and thus untreated until they become severe and significantly interfere with the patient's comfort, quality of life, and potentially survival. Given the increasing complexity of cancer care, psychosocial support must assume a more prominent role in the care of individuals with cancer. Routine use of a screening tool for psychosocial assessment may help facilitate early identification and intervention for individuals who are at risk for psychosocial problems. Based on the prevalence of psychosocial problems described in the literature and the paucity of psychosocial screening instruments that can be applied practically in the clinical setting, the development of a new instrument to identify patients with cancer who have psychosocial problems in multiple domains and who thus are at risk for excessive psychosocial distress throughout the course of treatment is presented. This article provides background information, reviews the literature, including instruments that have been used to screen patients in the oncology setting for psychosocial problems, and presents a new instrument based on current deficiencies in this area. Pilot testing of the instrument demonstrates its feasibility for use in the clinical setting.

Clinical Factors Associated With Mode of Death Following Cardiac Arrest

BACKGROUND

Death after resuscitation from cardiac arrest is common. Although associated factors have been identified, knowledge about their relationship with specific modes of death is limited.

OBJECTIVE

To identify clinical factors associated with specific modes of death following cardiac arrest.

METHODS

This study involved a retrospective medical record review of patients admitted to a single health care center from January 2015 to March 2020 after resuscitation from cardiac arrest who died during their index hospitalization. Mode of death was categorized as either brain death, withdrawal of life-sustaining therapies due to neurologic causes, death due to medical causes, or withdrawal of life-sustaining therapies due to patient preference. Clinical characteristics across modes of death were compared.

RESULTS

The analysis included 731 patients. Death due to medical causes was the most common mode of death. Compared with the other groups of patients, those with brain death were younger, had fewer comorbidities, were more likely to have experienced unwitnessed and longer cardiac arrest, and had more severe acidosis and hyperglycemia on presentation. Patients who died owing to medical causes or withdrawal of life-sustaining therapies due to patient preference were older and had more comorbidities, fewer unfavorable cardiac arrest characteristics, and fewer days between cardiac arrest and death.

CONCLUSIONS

Significant associations were found between several clinical characteristics and specific mode of death following cardiac arrest. Decision-making regarding withdrawal of care after resuscitation from cardiac arrest should be based on a multimodal approach that takes account of a variety of personal and clinical factors.
