Effect of a comprehensive health education program on pre-hospital delay intentions in high-risk stroke population and caregivers

Are we missing an opportunity? Prehospital delay in patients with acute ischemic stroke and known atrial fibrillation

INTRODUCTION AND OBJECTIVES

The follow-up of patients with atrial fibrillation (AF) presents an opportunity to alert patients and their families on how to recognize and act in the event of stroke. Our aim was to compare stroke recognition-to-door time and prehospital stroke code activation in patients with known AF (KAF) and AF detected after stroke (AFDAS).

METHODS

We performed a retrospective cohort study of consecutive patients receiving acute recanalization treatment for acute ischemic stroke between January 2016 and August 2022, with AF as a potential stroke cause. Patients were divided into KAF and AFDAS, and stroke recognition-to-door time and prehospital stroke code activation were compared. In the KAF subgroup, we assessed whether the use of preadmission anticoagulation was associated with the studied prehospital parameters.

RESULTS

We included 438 patients, 290 female (66.2%), mean age 79.3±9.4 years. In total, 238 patients had KAF (54.3%) and 200 (45.7%) had AFDAS. Of those with KAF, 114 (48.1%) were pretreated with anticoagulation. Patients with KAF and AFDAS had no differences in stroke recognition-to-door time (74.0 [55.0-101.0] vs. 78.0 [60.0-112.0] min; p=0.097) or prehospital stroke code activation [148 (64.6%) vs. 128 (65.3%); p=0.965]. In the KAF subgroup, preadmission anticoagulation did not influence stroke recognition-to-door time or mode of hospital admission.

CONCLUSION

Stroke recognition-to-door time and prehospital stroke code activation were similar between patients with known or newly diagnosed AF. Preadmission anticoagulation treatment also did not affect the studied parameters. Our findings highlight a missed opportunity to promote stroke knowledge in patients followed due to AF.

Do methods of hospital pre-alerts influence the on-scene times for acute pre-hospital stroke patients? A retrospective observational study

INTRODUCTION

Stroke is one of the leading causes of death and disability worldwide. The ambulance service is often the first medical service to reach an acute stroke patient, and due to the time-critical nature of stroke, a time-critical assessment and rapid transport to a hyper acute stroke unit are essential. As stroke services have been centralised, different hospitals have implemented different pre-alert admission policies that may affect the on-scene time of the attending ambulance crew. The aim of this study is to investigate if the different pre-alert admission policies affect time on scene.

METHOD

The current study is a retrospective quantitative observational study using data routinely collected by North East Ambulance Service NHS Foundation Trust. The time on scene was divided into two variables; group one was a telephone pre-alert in which a telephone discussion with the receiving hospital is required before they accept admission of the patient. Group two was a radio-style pre-alert in which the attending clinician makes an autonomous decision on the receiving hospital and alerts them via a short radio message of the incoming patient. These times were then compared to identify if there was any difference between them.

RESULTS

Data on 927 patients over a three-month period, from October to December 2019, who had received the full stroke bundle of care, were within the thrombolysis window and recorded as a stroke by the attending clinician, were split into the variable groups and reported on. The mean time on scene for a telephone call pre-alert was 33 minutes and 19 seconds, with a standard deviation of 13 minutes and 8 seconds. The mean on-scene time for a radio pre-alert was 28 minutes and 24 seconds, with a standard deviation of 11 minutes and 51 seconds.

CONCLUSION

A pre-alert given via radio instead of via telephone is shown to have a mean time saving of 4 minutes and 55 seconds, representing an important decrease in time which could be beneficial to patients.

Educational Program Improved Senior Preparedness to Call 911 as a Response to Stroke

OBJECTIVES

Stroke predominantly affects the elderly. Universities of the Third Age (U3A) are presented with an opportunity to target them. The goal of our study was to improve older adults' preparedness to call 911 as a response to symptoms of stroke.

MATERIALS AND METHODS

Participants were recruited from U3A in Brno, Czech Republic in year 2018. The program included an educational movie about stroke and testing with pretest posttest design. Stroke awareness was measured by Stroke Action Test and video-clips portraying stroke and stroke mimicking symptoms. Respondents had to answer close-ended questions. Composite scores were compared using paired t-test.

RESULTS

Data were obtained from 206 attendees of the program, that is 2% of all students, from 4 of 5 U3A in Brno. The mean test score improved from 80% to 87% (paired p < 0.001). Participants with a lower baseline knowledge improved by 12% (95% CI 9% to 16%) and with a higher baseline knowledge by 0% (95% CI 3% to 4%). The score for calling 911 for stroke mimicking symptoms improved from 29% to 20% (paired p < 0.001).

CONCLUSIONS

Video-based educational program improved senior preparedness to call 911 as a response to stroke. The improvement was mild, which is at least partly due to a high baseline level of preparedness of seniors active in U3A. A lower baseline knowledge was however associated with a bigger improvement, which might be important for use in a less active/educated population. Educational intervention also decreased intention to call 911 for stroke mimicking symptoms, which could have important implications for decreasing unnecessary activation of pre-hospital services.

A Community-Engaged Stroke Preparedness Intervention in Chicago

Background

We evaluated a community‐engaged stroke preparedness intervention that aimed to increase early hospital arrival and emergency medical services (EMS) utilization among patients with stroke in the South Side of Chicago, Illinois.

Methods and Results

We compared change in early hospital arrival (<3 hours from symptom onset) and EMS utilization before and after our intervention among patients with confirmed ischemic stroke at an intervention hospital on the South Side of Chicago with concurrent data from 6 hospitals in nonintervention communities on the North Side of Chicago and 17 hospitals in St Louis, Missouri. We assessed EMS utilization for suspected stroke secondarily, using geospatial information systems analysis of Chicago ambulance transports before and after our intervention. Among 21 497 patients with confirmed ischemic stroke across all sites, early arrival rates at the intervention hospital increased by 0.5% per month (95% CI, −0.2% to 1.2%) after intervention compared with the preintervention period but were not different from North Side Chicago hospitals (difference of −0.3% per month [95% CI, −0.12% to 0.06%]) or St Louis hospitals (difference of 0.7% per month [95% CI, −0.1% to 1.4%]). EMS utilization at the intervention hospital decreased by 0.8% per month (95% CI, −1.7% to 0.2%) but was not different from North Side Chicago hospitals (difference of 0.004% per month [95% CI, −1.1% to 1.1%]) or St Louis hospitals (difference of −0.7% per month [95% CI, −1.7% to 0.3%]). EMS utilization for suspected stroke increased in the areas surrounding the intervention hospital (odds ratio [OR], 1.4; 95% CI, 1.2–1.6) and in the South Side (OR, 1.2; 95% CI, 1.1–1.3), but not in the North Side (OR, 1.0; 95% CI, 0.9–1.1).

Conclusions

Following a community stroke preparedness intervention, early hospital arrival and EMS utilization for confirmed ischemic stroke did not increase. However, ambulance transports for suspected stroke increased in the intervention community compared with other regions.

Effects of personal characteristics, disease uncertainty and knowledge on family caregivers' preparedness of stroke survivors: a cross-sectional study

Family caregivers play an important role in the rehabilitation of stroke survivors. The aims of this study were to describe preparedness, uncertainty, and knowledge regarding stroke in family caregivers of people who have undergone strokes and to investigate factors influencing preparedness. A total of 306 caregivers completed the questionnaires, including the Caregiver Preparedness Scale, the Mishel Uncertainty in Illness Scale, and Knowledge of Stroke. The result showed that the mean score of the family caregivers' preparedness was 14.42, the mean score of disease uncertainty was 75.62, and the mean score of stroke knowledge was 10.41. Caregiver preparedness was negatively correlated with disease uncertainty and positively correlated with knowledge. Multivariate stepwise regression analysis showed that educational background, profession, caregiving experience and uncertainty degree of the family caregivers, gender, and age of stroke survivor could predict 45.90% of the total variation in preparedness. The findings suggest that demographic characteristics of stroke survivor and family caregiver, as well as caregivers' disease uncertainty, enable predict the level of caregiver preparedness. Medical professionals should pay attention to providing personalized and targeted approaches to maximize caregivers' preparedness.

Effectiveness of group visits for elderly patients with type 2 diabetes in an urban community in China

The purpose of this study is to evaluate the effectiveness of a group visit intervention in comparison with the usual care for elderly patients with type 2 diabetes in a community. We randomized 109 community elderly patients with type 2 diabetes to the intervention group (n = 55) of monthly group visits sessions or to a control group (n = 54) of usual care. Repeated measures analysis of variance was used to compare the changes in HbA1_C, diabetes knowledge, self-efficacy, and self-management behavior in both groups. At the 6-month follow-up, although no significant difference was observed between the groups regarding HbA1_C (p = 0.272). Diabetes knowledge, self-efficacy and self-management scores were higher in patients in the intervention group than that in the control group (p < 0.05). The group visits model increased diabetes knowledge and self-efficacy and improved patients' self-management behavior. The model was found suitable for helping these elderly patients with type 2 diabetes achieve effective self-management.

Relationship between the anxiety/depression and care burden of the major caregiver of stroke patients

To investigate the anxiety/depression of caregivers of stroke patients.This study used a cross-sectional survey design and convenience sampling.Totally, 117 caregivers of stroke patients were enrolled. Data were collected from questionnaires. Hamilton anxiety scale, Hamilton depression scale, and Zarit caregiver burden interview were performed. Multiple linear regression and correlation analysis were used.The anxiety score, depression score and total burden score of 117 stroke caregivers were 16.56 ± 8.02, 18.63 ± 9.39, and 25.88 ± 10.35, respectively. Anxiety symptoms, mild to moderate depressive symptoms, and severe depressive symptoms were found in 43.9%, 26.5%, and 27.4% of the caregivers, respectively. Daily care time and medical payment method were influencing factors for anxiety and depression (P < .05). Both anxiety and depression were positively correlated with total care burden score (P < .01).Anxiety and depression are common in the caregivers of stroke patients and are closely related to care burdens. In this regard, appropriate home care guidance, psychological counseling and social support should be provided to the caregivers to reduce their physical and mental burden.

Community Interventions to Increase Stroke Preparedness and Acute Stroke Treatment Rates

PURPOSE OF REVIEW

Acute stroke treatments reduce the risk of post-stroke disability. These treatments, tissue plasminogen activator (tPA) and intra-arterial treatment, are highly time-dependent; thus, one of the main barriers to treatment is pre-hospital delay. Stroke preparedness is defined as the ability to recognize stroke symptoms and the intent to activate emergency medical services (EMS). This review describes types of acute stroke treatment and preparedness interventions, including recent mass media interventions to increase acute stroke treatment rates, and adult and youth community interventions to increase stroke preparedness.

RECENT FINDINGS

The mass media campaigns show mixed results regarding acute stroke treatment rates, possibly attributed to the various media platforms utilized and resources available. The adult and youth community interventions reveal an overall increase in stroke symptom recognition and behavioral intent to call EMS. However, most of these community interventions were not grounded in health behavior theory, and they were tested in single group, pre-post test study designs that assessed behavioral rather than clinical outcomes. The delivery of stroke preparedness information by youth to adults, for example via home assignments, is a promising and innovative approach to stroke preparedness. Mass media and community interventions show promise to increase stroke preparedness and acute stroke treatment rates. The development of health behavior theory-based interventions that are tested via scientifically rigorous study designs are needed to prioritize which interventions should be disseminated to culturally and socially similar communities.
