Essential Workflow and Performance Measures for Optimizing Acute Ischemic Stroke Treatment in India

IMPETUS Stroke: Assessment of hospital infrastructure and workflow for implementation of uniform stroke care pathway in India

BACKGROUND

India accounts for 13.3% of global disability-adjusted life years (DALYs) lost due to stroke with a relatively younger age of onset compared to the Western population. In India's public healthcare system, many stroke patients seek care at tertiary-level government-funded medical colleges where an optimal level of stroke care is expected. However, there are no studies from India that have assessed the quality of stroke care, including infrastructure, imaging facilities, or the availability of stroke care units in medical colleges.

AIM

This study aimed to understand the existing protocols and management of acute stroke care across 22 medical colleges in India, as part of the baseline assessment of the ongoing IMPETUS stroke study.

METHODS

A semi-structured quantitative pre-tested questionnaire, developed based on review of literature and expert discussion, was mailed to 22 participating sites of the IMPETUS stroke study. The questionnaire assessed comprehensively all components of stroke care, including human resources, emergency system, in-hospital care, and secondary prevention. A descriptive analysis of their status was undertaken.

RESULTS

In the emergency services, limited stroke helpline numbers, 3/22 (14%); prenotification system, 5/22 (23%); and stroke-trained physicians were available, 6/22 (27%). One-third of hospitals did not have on-call neurologists. Although non-contrast computed tomography (NCCT) was always available, 39% of hospitals were not doing computed tomography (CT) angiography and 13/22 (59%) were not doing magnetic resonance imaging (MRI) after routine working hours. Intravenous thrombolysis was being done in 20/22 (91%) hospitals, but 36% of hospitals did not provide it free of cost. Endovascular therapy was available only in 6/22 (27%) hospitals. The study highlighted the scarcity of multidisciplinary stroke teams, 8/22 (36%), and stroke units, 7/22 (32%). Lifesaving surgeries like hematoma evacuation, 11/22 (50%), and decompressive craniectomy, 9/22 (41%), were performed in limited numbers. The availability of occupational therapists, speech therapists, and cognitive rehabilitation was minimal.

CONCLUSION

This study highlighted the current status of acute stroke management in publicly funded tertiary care hospitals. Lack of prenotification, limited number of stroke-trained physicians and neurosurgeons, relatively lesser provision of free thrombolytic agents, limited stroke units, and lack of rehabilitation services are areas needing urgent attention by policymakers and creation of sustainable education models for uniform stroke care by medical professionals across the country.

Stroke systems of care in South-East Asia Region (SEAR): commonalities and diversities

The Southeast Asia Region (SEAR) accounts for nearly 50% of the developing world's stroke burden. With various commonalities across its countries concerning health services, user awareness, and healthcare-seeking behavior, SEAR still presents profound diversities in stroke-related services across the continuum of care. This review highlights the numerous systems and challenges in access to stroke care, acute stroke care services, and health care systems, including rehabilitation. The paper has also attempted to compile information on the availability of stroke specialized centers, Intravenous thrombolysis (IVT) ready centers, Endovascular therapy (EVT) ready centers, rehabilitation centers, and workforce against a backdrop of each country's population. Lastly, the efforts of WHO (SEARO)-CMCL (World Health Organization-South East Asia region, Christian Medical College & Hospital Ludhiana) collaboration towards improving stroke services and capacity among the SEAR have been described.

Characteristics, clinical practice patterns, and outcomes of strokes in India: INSPIRE-A multicentre prospective study

BACKGROUND

India has a high burden of stroke, but there are limited data available on the characteristics of patients presenting with stroke in India.

AIMS

We aimed to document the clinical characteristics, practice patterns, and outcomes of patients presenting with acute stroke to Indian hospitals.

METHODS

A prospective registry study of patients admitted with acute clinical stroke was conducted in 62 centers across different regions in India between 2009 and 2013.

RESULTS

Of the 10,329 patients included in the prescribed registry, 71.4% had ischemic stroke, 25.2% had intracerebral hemorrhage (ICH), and 3.4% had an undetermined stroke subtype. Mean age was 60 years (SD = 14) with 19.9% younger than 50 years; 65% were male. A severe stroke at admission (modified-Rankin score 4-5) was seen in 62%, with 38.4% of patients having severe disability at discharge or dying during hospitalization. Cumulative mortality was 25% at 6 months. Neuroimaging was completed in 98%, 76% received physiotherapy, 17% speech and language therapy (SLT), 7.6% occupational therapy (OT), with variability among sites; 3.7% of ischemic stroke patients received thrombolysis. Receipt of physiotherapy (odds ratio (OR) = 0.41, 95% confidence interval (CI): 0.33-0.52) and SLT (OR = 0.45, 95% CI: 0.32-0.65) was associated with lower mortality, while a history of atrial fibrillation (OR = 2.22, 95% CI: 1.37-3.58) and ICH (OR = 2.00, 95% CI: 1.66-2.40) were associated with higher mortality.

CONCLUSION

In the INSPIRE (In Hospital Prospective Stroke Registry) study, one-in-five patients with acute stroke was under 50 years of age, and one-quarter of stroke was ICH. There was a low provision of thrombolysis and poor access to multidisciplinary rehabilitation highlighting how improvements are needed to reduce morbidity and mortality from stroke in India.

Global, regional, and national time trends in mortality for stroke, 1990-2019: An age-period-cohort analysis for the global burden of disease 2019 study and implications for stroke prevention

BACKGROUND

Despite the fact that stroke is the second leading cause of death globally, a comprehensive and comparable assessment of mortality, and epidemiologic trends has not been conducted for most regions.We estimated the global and regional burden of stroke from 1990 to 2019 using data from the 2019 Global Study of Diseases, Injuries, and Risk Factors.

METHODS

For the period between 1990 and 2019, we used an age-period-cohort model to calculate the annual percentage changes in mortality (net drifts), local drifts, and period and cohort relative risks (period/cohort effects). Meanwhile, to quantify the temporal trends in stroke age-standardised mortality rate (ASMR), Average annual percentage changes (AAPCs) were determined by sex, area. With the potential to uncover disparities and treatment gaps in stroke care, this approach enables the examination and differentiation of age, period, and cohort effects in mortality trends.

FINDINGS

Global stroke deaths in 2019 were 6,552,725 (95% UI 5,995,200 to 7,015,139). Between 1990 and 2019, the ASMR declined globally by 36.43% (95% UI -41.65 to -31.2), with decreases in all SDI quintiles. The net drift in stroke mortality from 1990 to 2019 varied from -2.83% per year (95% confidence interval [CI]:-3.39 to -2.77) in countries with a high Socio-demographic Index (SDI) to -1.21% per year (95% CI: -1.26 to -1.16) in countries with a low SDI. During the past 30 years, favorable mortality reductions were generally found in high-SDI countries (net drift = -3.1% [95% CI: -3.4 to -2.8] per year) and high-middle SDI countries (-2.8% [-3.0 to -2.6]). However, 31 of 204 countries had either increasing trends (net drifts≥0.0%) or stagnated reductions (≥ - 0.5%) in mortality. The relative risk of mortality generally showed improving trends over time and in successively younger birth cohorts among high and high-middle SDI countries, with the exceptions of Kuwait, Ukraine, Kazakhstan, Guam, RussianFederation, Lithuania, Turkey, Montenegro, Serbia, Bosnia and Herzegovin, and Bulgaria.

INTERPRETATION

Notwithstanding mortality from stroke has increased globally over the past 30 years, adverse period and cohort effects have been found in many countries, calling into question the adequacy of healthcare for stroke patients of all ages. These lapses have a significant impact on the likelihood of achieving the Sustainable Development Goal (SDG) targets on mortality from age 60+ and NCDs.

Stroke Thrombolysis: Beating the Clock

Background

Recombinant tissue plasminogen activator (rtPA) has revolutionized the management of acute ischemic stroke. Shorter door-to-imaging and door-to-needle (DTN) times are crucial for improving the outcomes in thrombolysed patients. Our observational study evaluated the door-to-imaging time (DIT) and DTN times for all thrombolysed patients.

Materials and methods

The study was a cross-sectional observational study over a period of 18 months at a tertiary care teaching hospital and included 252 acute ischemic stroke patients of which 52 underwent thrombolysis with rtPA. The time intervals between arrival to neuroimaging and initiation of thrombolysis were noted.

Result

Of the total patients thrombolysed, only 10 patients underwent neuroimaging [non-contrast computed tomography (NCCT) head with MRI brain screen] within 30 minutes of their arrival in the hospital, 38 patients within 30-60 minutes and 2 each within the 61-90 and 91-120 minute time frames. The DTN time was 30-60 minutes for 3 patients, while 31 patients were thrombolysed within 61-90 minutes, 7 patients within 91-120 minutes, while 5 each took 121-150 and 151-180 minutes for the same. One patient had a DTN between 181 and 210 minutes.

Conclusion

Most patients included in the study underwent neuroimaging within 60 minutes and subsequent thrombolysis within 60-90 minutes of their arrival in the hospital. But the time frames did not meet the recommended ideal intervals, and further streamlining of stroke management is needed even at tertiary care centers in India.

Stroke in India: A systematic review of the incidence, prevalence, and case fatality

BACKGROUND

The burden of stroke is increasing in India; stroke is now the fourth leading cause of death and the fifth leading cause of disability. Previous research suggests that the incidence of stroke in India ranges between 105 and 152/100,000 people per year. However, there is a paucity of available data and a lack of uniform methods across published studies.

AIM

To identify high-quality prospective studies reporting the epidemiology of stroke in India.

SUMMARY OF REVIEW

A search strategy was modified from the Cochrane Stroke Strategy and adapted for a range of bibliographic databases from January 1997 to August 2020. From 7717 identified records, nine studies were selected for inclusion; three population-based registries, a further three population-based registries also using community-based ascertainment and three community-based door-to-door surveys. Studies represented the four cities of Mumbai, Trivandrum, Ludhiana, Kolkata, the state of Punjab, and 12 villages of Baruipur in the state of West Bengal. The total population denominator was 22,479,509 and 11,654 (mean 1294 SD 1710) people were identified with incident stroke. Crude incidence of stroke ranged from 108 to 172/100,000 people per year, crude prevalence from 26 to 757/100,000 people per year, and one-month case fatality rates from 18% to 42%.

CONCLUSIONS

Further high-quality evidence is needed across India to guide stroke policy and inform the development and organization of stroke services. Future researchers should consider the World Health Organization STEPwise approach to Surveillance framework, including longitudinal data collection, the inclusion of census population data, and a combination of hospital-registry and comprehensive community ascertainment strategies to ensure complete stroke identification.

Exploring the Essential Stroke Care Structures in Tertiary Healthcare Facilities in Rivers State, Nigeria

This study evaluated the essential stroke care structure available in the two Tertiary Health Facilities in Rives State, Nigeria. This was a descriptive survey involving the Stroke Care Survey and Assessment Tool (checklist/questionnaire) developed by the World Stroke Organisation to obtain information about the available essential stroke care structure (facilities, equipment, personnel and management protocol) at the two tertiary health facilities (RSUTH & UPTH). The study gathered relevant information, which was summarised into tables and graphs using Microsoft Excel 2016. From the results, although facilities had A and E departments, dedicated stroke units (fixed or mobile) were unavailable, and there was no locally developed protocol to support rapid triage of stroke patients. The facilities and equipment were either unavailable or insufficient. Only one health facility (RSUTH) provided 24 hrs/7 days laboratory services. The workforces were a mix between regular clinical staff and some specialists. Tissue plasminogen activator (tPA) use was non-existent, though specialists were trained on its administration. There was no locally developed or adopted stroke-specific clinical guidelines. In conclusion, the structural services available for stroke care within the studied tertiary health facilities were poor, unavailable or grossly insufficient. The state facility (RSUTH) suffered the most in terms of unavailable national support and staff development.
