Abstract
INTRODUCTION In patients undergoing dialysis, major bone fracture is associated with a high risk of mortality, including death of cardiovascular (CV) origin. In the present study, we aimed to determine whether a history of fragility fracture is a predictor of CV death in patients undergoing hemodialysis with long-term follow-up. MATERIALS AND METHODS In total, 3499 patients undergoing hemodialysis were analyzed for 10 years. We evaluated the history of fragility fracture in each patient at enrollment. The primary outcome was CV death. A Cox proportional hazard model and a competing risk approach were applied to determine the association between a history of fragility fracture and CV death. RESULTS A total of 346 patients had a history of fragility fracture at enrollment. During a median follow-up of 8.8 years, 1730 (49.4%) patients died. Among them, 621 patients experienced CV death. Multivariable Cox analyses after adjustment for confounding variables showed that a history of fragility fracture was associated with CV death (hazard ratio, 1.47; 95% confidence interval, 1.16-1.85). In the Fine-Gray regression model, a history of fragility fracture was an independent risk factor for CV death (subdistribution hazard ratio, 1.36; 95% confidence interval, 1.07-1.72). CONCLUSION In a large cohort of patients undergoing hemodialysis, a history of fragility fracture was an independent predictor of CV death.

Abstract
BACKGROUND Understanding factors that influence the transition to permanent residential aged care following a stroke or transient ischemic attack may inform strategies to support people to live at home longer. We aimed to identify the demographic, clinical, and system factors that may influence the transition from living in the community to permanent residential care in the 6 to 18 months following stroke/transient ischemic attack. METHODS Linked data cohort analysis of adults from Queensland and Victoria aged ≥65 years and registered in the Australian Stroke Clinical Registry (2012-2016) with a clinical diagnosis of stroke/transient ischemic attack and living in the community in the first 6 months post-hospital discharge. Participant data were linked with primary care, pharmaceutical, aged care, death, and hospital data. Multivariable survival analysis was performed to determine demographic, clinical, and system factors associated with the transition to permanent residential care in the 6 to 18 months following stroke, with death modeled as a competing risk. RESULTS Of 11 176 included registrants (median age, 77.2 years; 44% female), 520 (5%) transitioned to permanent residential care between 6 and 18 months. Factors most associated with transition included the history of urinary tract infections (subhazard ratio [SHR], 1.41 [95% CI, 1.16-1.71]), dementia (SHR, 1.66 [95% CI, 1.14-2.42]), increasing age (65-74 versus 85+ years; SHR, 1.75 [95% CI, 1.31-2.34]), living in regional Australia (SHR, 31 [95% CI, 1.08-1.60]), and aged care service approvals: respite (SHR, 4.54 [95% CI, 3.51-5.85]) and high-level home support (SHR, 1.80 [95% CI, 1.30-2.48]). Protective factors included being dispensed antihypertensive medications (SHR, 0.68 [95% CI, 0.53-0.87]), seeing a cardiologist (SHR, 0.72 [95% CI, 0.57-0.91]) following stroke, and less severe stroke (SHR, 0.71 [95% CI, 0.58-0.88]). CONCLUSIONS Our findings provide an improved understanding of factors that influence the transition from community to permanent residential care following stroke and can inform future strategies designed to delay this transition.

Comparison between healthcare quality in primary stroke centers and comprehensive stroke centers for acute stroke patients: evidence from the Chinese Stroke Center Alliance. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 38:100863. [PMID: 37577368 PMCID: PMC10416019 DOI: 10.1016/j.lanwpc.2023.100863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 07/12/2023] [Accepted: 07/16/2023] [Indexed: 08/15/2023]
Abstract
Background To improve stroke care quality, the guidelines for stroke center construction in China recommended establishing primary stroke centers (PSCs) and comprehensive stroke centers (CSCs). We aimed to compare stroke care quality between the two types of centers. Methods Data were collected from acute stroke patients admitted to PSCs or CSCs in the China Stroke Center Alliance program. Twenty-one individual guideline-recommended performance measures and two summary measures were compared between the two groups. Multivariable logistic regression models were used to examine the association between stroke center status (CSC vs. PSC) and healthcare quality. Findings Data from 750,594 stroke patients from 1474 stroke centers (252 CSCs and 1222 PSCs) were analyzed. For many components of healthcare performance in stroke patients, comparable levels of performance were observed between CSCs and PCSs. Nonetheless, CSCs outperformed PSCs in the areas of administering intravenous recombinant tissue plasminogen activator within 4.5 h (aOR = 1.31 [95% CI: 1.07-1.60]), rehabilitation for acute ischaemic stroke (AIS) (aOR = 1.19 [95% CI: 1.01-1.40]), and the provision of hypoglycemic medication and statin therapy upon discharge for AIS (aOR = 1.26 [95% CI: 1.00-1.59] and aOR = 1.28 [95% CI: 1.04-1.59], respectively). More patients with intracerebral haemorrhage and subarachnoid haemorrhage received neurosurgery in CSCs (14.4% vs. 10.6% and 51.0% vs. 33.9%, respectively). Additionally, CSCs had higher in-hospital mortality than PSCs (aOR = 1.33 [95% CI: 1.01-1.73]). Interpretation Overall PSCs provided equivalent care for many quality measures to CSCs in China with the exception of thrombolysis, rehabilitation access, and medication at discharge for AIS, whereby improvements should be directed. Nevertheless, PSCs have demonstrated lower risk-adjusted in-hospital mortality rates. Funding The National Key Research and Development Projects of China.

Abstract
Blood pressure (BP) is the most important modifiable risk factor for intracerebral hemorrhage (ICH). Elevated BP is associated with an increased risk of ICH, worse outcome after ICH, and in survivors, higher risks of recurrent ICH, ischemic stroke, myocardial infarction, and cognitive impairment/dementia. As intensive BP control probably improves the chances of recovery from acute ICH, the early use of intravenous or oral medications to achieve a systolic BP goal of <140 mm Hg within the first few hours of presentation is reasonable for being applied in most patients. In the long-term, oral antihypertensive drugs should be titrated as soon as possible to achieve a goal BP <130/80 mm Hg and again in all ICH patients regardless of age, location, or presumed mechanism of ICH. The degree of sustained BP reduction, rather than the choice of BP-lowering agent(s), is the most important factor for optimizing risk reduction, with varying combinations of thiazide-type diuretics, long-acting calcium channel blockers, ACE (angiotensin-converting enzyme) inhibitors or angiotensin receptor blockers, being the mainstay of therapy. As most patients will require multiple BP-lowering agents, and physician inertia and poor adherence are major barriers to effective BP control, single-pill combination therapy should be considered as the choice of management where available. Increased population and clinician awareness, and innovations to solving patient, provider, and social factors, have much to offer for improving BP control after ICH and more broadly across high-risk groups. It is critical that all physicians, especially those managing ICH patients, emphasize the importance of BP control in their practice.

Abstract
BACKGROUND AND PURPOSE Although a target of 80% medication adherence is commonly cited, it is unclear whether greater adherence improves survival after stroke or transient ischemic attack (TIA). We investigated associations between medication adherence during the first year postdischarge, and mortality up to 3 years, to provide evidence-based targets for medication adherence. METHODS Retrospective cohort study of 1-year survivors of first-ever stroke or TIA, aged ≥18 years, from the Australian Stroke Clinical Registry (July 2010-June 2014) linked with nationwide prescription refill and mortality data (until August 2017). Adherence to antihypertensive agents, statins, and nonaspirin antithrombotic medications was based on the proportion of days covered from discharge until 1 year. Cox regression with restricted cubic splines was used to investigate nonlinear relationships between medication adherence and all-cause mortality (to 3 years postdischarge). Models were adjusted for age, sex, socioeconomic position, stroke factors, primary care factors, and concomitant medication use. RESULTS Among 8363 one-year survivors of first-ever stroke or TIA (44% aged ≥75 years, 44% female, 18% TIA), 75% were supplied antihypertensive agents. In patients without intracerebral hemorrhage (N=7446), 84% were supplied statins, and 65% were supplied nonaspirin antithrombotic medications. Median adherence was ≈90% for each medication group. Between 1% and 100% adherence, greater adherence to statins or antihypertensive agents, but not nonaspirin antithrombotic agents, was associated with improved survival. When restricted to linear regions above 60% adherence, each 10% increase in adherence was associated with a reduction in all-cause mortality of 13% for antihypertensive agents (hazard ratio, 0.87 [95% CI, 0.81-0.95]), 13% for statins (hazard ratio, 0.87 [95% CI, 0.80-0.95]), and 15% for nonaspirin antithrombotic agents (hazard ratio, 0.85 [95% CI, 0.79-0.93]). CONCLUSIONS Greater levels of medication adherence after stroke or TIA are associated with improved survival, even among patients with near-perfect adherence. Interventions to improve medication adherence are needed to maximize survival poststroke.

Abstract
Stroke is one of the main causes of mortality and permanent disability. Secondary prevention of stroke recurrence therefore has a high priority. Secondary prevention of ischemic stroke includes optimization of the lifestyle and diet, treatment of risk factors, such as hypertension, diabetes mellitus and hyperlipidemia, prophylaxis of recurrence with antiplatelet treatment in patients with high vascular risk and anticoagulation in atrial fibrillation. In addition, secondary prevention includes carotid surgery or stenting in selected symptomatic patients and closure of a patent foramen ovale after cryptogenic stroke.

Abstract
OBJECTIVE We aim to report the accuracy of linking data from a non-government-held clinical quality registry to national claims data and identify associated sources of systematic bias. METHODS Patients with stroke or transient ischaemic attack admitted to hospitals participating in the Australian Stroke Clinical Registry (AuSCR) were linked with Medicare and medication dispensings through the Australian Medicare enrolment file (MEF). The proportion of registrants in the datasets was calculated and factors associated with a non-merge assessed using multivariable analyses. RESULTS A total of 17,980 AuSCR registrants (January 2010 - July 2014) were submitted for linkage (median age 76 years; 46% female; 67% ischaemic stroke); the proportion merged was 97% MEF, 93% Medicare and 95% medication dispensings. Data from registrants born in Asia were less likely to link with the MEF (adjusted Odds Ratio [aOR]: 0.20; 95%Confidence Interval [CI]: 0.15, 0.27). Data for those aged 85-plus compared to those under 65 years were less likely to merge with Medicare (aOR 0.25; 95%CI:0.21, 0.30) but more likely to merge with dispensing claims data (aOR: 2.15 (95%CI:1.71, 2.69). Implications for public health: Linkage between the AuSCR, a national clinical quality registry and Commonwealth datasets was achieved and potential sources of bias were identified.

Abstract
Stroke is a major cause of death and disability globally. Diagnosis depends on clinical features and brain imaging to differentiate between ischaemic stroke and intracerebral haemorrhage. Non-contrast CT can exclude haemorrhage, but the addition of CT perfusion imaging and angiography allows a positive diagnosis of ischaemic stroke versus mimics and can identify a large vessel occlusion target for endovascular thrombectomy. Management of ischaemic stroke has greatly advanced, with rapid reperfusion by use of intravenous thrombolysis and endovascular thrombectomy shown to reduce disability. These therapies can now be applied in selected patients who present late to medical care if there is imaging evidence of salvageable brain tissue. Both haemostatic agents and surgical interventions are investigational for intracerebral haemorrhage. Prevention of recurrent stroke requires an understanding of the mechanism of stroke to target interventions, such as carotid endarterectomy, anticoagulation for atrial fibrillation, and patent foramen ovale closure. However, interventions such as lowering blood pressure, smoking cessation, and lifestyle optimisation are common to all stroke subtypes.

Abstract
Background and Purpose—
Despite evidence to support the prescription of antihypertensive medications before hospital discharge to promote medication adherence and prevent recurrent events, many patients with stroke miss out on these medications at discharge. We aimed to examine patient, clinical, and system-level differences in the prescription of antihypertensive medications at hospital discharge after stroke.
Methods—
Adults with acute ischemic stroke or intracerebral hemorrhage alive at discharge were included (years 2009–2013) from 39 hospitals participating in the Australian Stroke Clinical Registry. Patient comorbidities were identified using the
International Statistical Classification of Diseases and Related Health Problems (Tenth Edition, Australian Modification
) codes from the hospital admissions and emergency presentation data. The outcome variable and other system factors were derived from the Australian Stroke Clinical Registry dataset. Multivariable, multilevel logistic regression was used to examine factors associated with the prescription of antihypertensive medications at hospital discharge.
Results—
Of the 10 315 patients included, 79.0% (intracerebral hemorrhage, 74.1%; acute ischemic stroke, 79.8%) were prescribed antihypertensive medications at discharge. Prescription varied between hospital sites, with 6 sites >2 SDs below the national average for provision of antihypertensives at discharge. Prescription was also independently associated with patient and clinical factors including history of hypertension, diabetes mellitus, management in an acute stroke unit, and discharge to rehabilitation. In patients with acute ischemic stroke, females (odds ratio, 0.85; 95% CI, 0.76–0.94), those who had greater stroke severity (odds ratio, 0.81; 95% CI 0.72–0.92), or dementia (odds ratio, 0.65; 95% CI, 0.52–0.81) were less likely to be prescribed.
Conclusions—
Prescription of antihypertensive medications poststroke varies between hospitals and according to patient factors including age, sex, stroke severity, and comorbidity profile. Implementation of targeted quality improvement initiatives at local hospitals may help to reduce the variation in prescription observed.

Abstract
INTRODUCTION The growing burden of chronic diseases means some governments have been providing financial incentives for multidisciplinary care and self-management support delivered within primary care. Currently, population-based evaluations of the effectiveness of these policies are lacking. AIM To outline the methodological approach for our study that is designed to evaluate the effectiveness (including cost) of primary care policies for chronic diseases in Australia using stroke as a case study. METHODS Person-level linkages will be undertaken between registrants from the Australian Stroke Clinical Registry (AuSCR) and (i) Government-held Medicare Australia claims data, to identify receipt or not of chronic disease management and care coordination primary care items; (ii) state government-held hospital data, to define outcomes; and (iii) government-held pharmaceutical and aged care claims data, to define covariates. N=1500 randomly selected AuSCR registrants will be sent surveys to obtain patient experience information. In Australia, unique identifiers are unavailable. Therefore, personal-identifiers will be submitted to government data linkage units. Researchers will merge the de-identified datasets for analysis using a project identifier. An economic evaluation will also be undertaken. ANALYSIS The index event will be the first stroke recorded in the AuSCR. Multivariable competing risks Poisson regression for multiple events, adjusted by a propensity score, will be used to test for differences in the rates of hospital presentations and medication adherence for different care (policy) types. Our estimated sample size of 25,000 patients will provide 80% estimated power (ɑ>0.05) to detect a 6-8% difference in rates. The incremental costs per Quality-adjusted life years gained of community-based care following the acute event will be estimated from a health sector perspective. CONCLUSION Completion of this study will provide a novel and comprehensive evaluation of the effectiveness and cost-effectiveness of Australian primary care policies. Its success will enable us to highlight the value of data-linkage for this type of research.

Abstract
BACKGROUND The quality of stroke care may diminish on weekends. AIMS We aimed to compare the quality of care and outcomes for patients with stroke/transient ischemic attack discharged on weekdays compared with those discharged on weekends. METHODS Data from the Australian Stroke Clinical Registry from January 2010 to December 2015 (n = 45 hospitals) were analyzed. Differences in processes of care by the timing of discharge are described. Multilevel regression and survival analyses (up to 180 days postevent) were undertaken. RESULTS Among 30,649 registrants, 2621 (8.6%) were discharged on weekends (55% male; median age 74 years). Compared to those discharged on weekdays, patients discharged on weekends were more often patients with a transient ischemic attack (weekend 35% vs. 19%; p < 0.001) but were less often treated in a stroke unit (69% vs. 81%; p < 0.001), prescribed antihypertensive medication at discharge (65% vs. 71%; p < 0.001) or received a care plan if discharged to the community (47% vs. 53%; p < 0.001). After accounting for patient characteristics and clustering by hospital, patients discharged on weekends had a 1 day shorter length of stay (coefficient = -1.31, 95% confidence interval [CI] = -1.52, -1.10), were less often discharged to inpatient rehabilitation (aOR = 0.39, 95% CI = 0.34, 0.44) and had a greater hazard of death within 180 days (hazard ratio = 1.22, 95% CI = 1.04, 1.42) than those discharged on weekdays. CONCLUSIONS Patients with stroke/transient ischemic attack discharged on weekends were more likely to receive suboptimal care and have higher long-term mortality. High quality of stroke care should be consistent irrespective of the timing of hospital discharge.
