Clinical characteristic of a Haitian stroke cohort and a scoping review of the literature of stroke among the Haitian population.

Background and Aim: There are significant disparities in stroke care and outcomes between low- and middle-income countries compared to high-income countries. Haiti, a lower-middle-income country, suffers from a lack of resources for acute stroke management. This study is the first to report the epidemiological profile of the Haitian population presenting with stroke symptoms at the largest academic hospital in the nation. Methods: This is an observational study conducted over a period of 5 months from April 2021 to August 2021 in the Internal Medicine Department of the State University Hospital of Haiti. There were 51 included patients who were suspected to have had an acute stroke. A descriptive statistical analysis was conducted. A scoping review of the literature was also conducted. Results: Over 50% of included patients were between 19 and 65 years old. The mean age at presentation was 61 years, and patients were predominantly female (64.7%). The prevalence of severe motor deficits was over 96%. The mean National Institutes of Health Stroke Scale was 12. Only 15.7% of patients (8/51) had a computed tomography (CT) scan during their hospitalization. The median time to CT scan was 84 h after symptom onset. About 80% of those with complications took more than 24 h to arrive at the hospital after the onset of symptoms. Eleven percent of patients had complications, and the mortality rate was 3.9%. There was a significant association between the Modified Rankin Scale and the occurrence of complications (p = 0.016). National Institutes of Health Stroke Scale (NIHSS) score had a significant association with the Glasgow score (F = 6.3; p < 0.001) where an inversely proportional correlation was observed between them (r = -0.7; p < 0.001) and a proportional correlation with the Rankin prediction score and the NIHSS (r = 0.3, p = 0.04). Little is known about the epidemiology of stroke patients in Haiti, and this limits the ability to develop targeted interventions to improve outcomes. In our scoping review, only three pertinent studies were identified over a 25-year period, this leads to a lack of data in regard to stroke care in Haiti mainly due to the absence of trained personnel. Conclusion: In our cohort, stroke is mainly affecting female patients. The majority of stroke patients have moderate to severe motor deficits and took more than 24 h to arrive at the hospital. Urgent assistance is needed to strengthen personnel and infrastructure dedicated to stroke. Neurological assessment based on NIHSS and Rankin score should be systematic in stroke evaluation in Haiti. Relevance for Patients: This study is relevant for patients because it emphasizes the challenges of stroke management in Haiti due to the non-availability of reference drugs, the time to arrive at the hospital to start treatment, as well as the means of diagnosis which are limited, like the CT scan. While stroke prevalence is on the rise in the country, it is the highest in the Caribbean and Latin America region.

A 10-year review of antihypertensive prescribing practices after stroke and the associated disparities from the Florida Stroke Registry.

Background: Guideline based hypertension management is integral to the prevention of stroke. We examine trends in antihypertensive medications prescribed after stroke and assess how well a prescribers' blood pressure medication choice adheres to clinical practice guidelines (Prescribers'-Choice Adherence). Methods: The Florida Stroke registry (FSR) utilizes statewide data prospectively collected for all acute stroke admissions. Based on established guidelines we defined optimal Prescribers'-Choice Adherence using the following hierarchy of rules: 1) use of an angiotensin inhibitor (ACEI) or angiotensin receptor blocker (ARB) as first-line antihypertensive among diabetics; 2) use of thiazide-type diuretics or calcium channel blockers (CCB) among African-American patients; 3) use of beta-adrenergic blockers (BB) among patients with compelling cardiac indication (CCI) 4) use of thiazide, ACEI/ARB or CCB class as first-line in all others; 5) BB should be avoided as first line unless CCI. RESULTS: A total of 372,254 cases from January 2010 to March 2020 are in FSR with a diagnosis of acute ischemic, hemorrhagic stroke, transient ischemic attack or subarachnoid hemorrhage; 265,409 with complete data were included in the final analysis. Mean age 70 +/-14 years, 50% female, index stroke subtype of 74% acute ischemic stroke and 11% intracerebral hemorrhage. Prescribers'-Choice Adherence to each specific rule ranged from 48-74% which is below quality standards of 85%. There were race-ethnic disparities with only 49% Prescribers choice Adherence for African Americans patients. Conclusion: This large dataset demonstrates consistently low rates of Prescribers'-Choice Adherence over 10 years. There is an opportunity for quality improvement in hypertensive management after stroke.

Predictors of hyperglycaemic crises and their associated mortality in Jamaica.

The objective of the study was to determine the clinical characteristics and mortality of patients with hyperglycaemic hyperosmolar syndrome (HHS) and diabetic ketoacidosis (DKA) at a Jamaican tertiary care hospital. In a retrospective study of 1560 admissions for diabetes during the period 1998-2002, 980 dockets were reviewed and 164 individuals met the ADA diagnostic criteria for DKA or HHS. Patients with HHS were older than DKA patients (64.5 years [95% CI: 60.7-68.4] versus 35.9 years [95% CI: 30.2-41.6]), but were not more likely to be non-compliant with medications, infected, or male. Overall, 24% had a mixed DKA/HHS syndrome. Most DKA patients had type 2 diabetes (62%). Only 2% of HHS and 6% of DKA/HHS patients had type 1 diabetes. Syndrome specific mortality was: DKA 6.7%, HHS 20.3%, and DKA/HHS 25% (p for trend=0.013). Mortality increased significantly with age, especially in patients > or =50 years. Significant univariate predictors of mortality were altered mental status on admission, co-existing medical disease, increasing age, older age at onset of diabetes, acute stressors, and DKA/HHS. In multivariate models, only altered mental status was significant (OR=3.59; 95% CI: 1.24-10.41). Hence, hyperglycaemic crises in a Jamaican tertiary care hospital are associated with significant mortality especially in patients who are older or with altered mental status.
