Nationwide Big Data Analysis of Statin Use and Intracerebral Hemorrhage Risk in Acute Ischemic Stroke Patients in Taiwan.

Background and Objectives: Although statins are recommended for secondary prevention of acute ischemic stroke, some population-based studies and clinical evidence suggest that they might be used with an increased risk of intracranial hemorrhage. In this nested case-control study, we used Taiwan's nationwide universal health insurance database to investigate the possible association between statin therapy prescribed to acute ischemic stroke patients and their risk of subsequent intracerebral hemorrhage and all-cause mortality in Taiwan. Materials and Methods: All data were retrospectively obtained from Taiwan's National Health Insurance Research Database. Acute ischemic stroke patients were divided into a cohort receiving statin pharmacotherapy and a control cohort not receiving statin pharmacotherapy. A 1:1 matching for age, gender, and index day, and propensity score matching was conducted, producing 39,366 cases and 39,366 controls. The primary outcomes were long-term subsequent intracerebral hemorrhage and all-cause mortality. The competing risk between subsequent intracerebral hemorrhage and all-cause mortality was estimated using the Fine and Gray regression hazards model. Results: Patients receiving statin pharmacotherapy after an acute ischemic stroke had a significantly lower risk of subsequent intracerebral hemorrhage (p < 0.0001) and lower all-cause mortality rates (p < 0.0001). Low, moderate, and high dosages of statin were associated with significantly decreased risks for subsequent intracerebral hemorrhage (adjusted sHRs 0.82, 0.74, 0.53) and all-cause mortality (adjusted sHRs 0.75, 0.74, 0.74), respectively. Conclusions: Statin pharmacotherapy was found to safely and effectively reduce the risk of subsequent intracerebral hemorrhage and all-cause mortality in acute ischemic stroke patients in Taiwan.

Comparison of Cost-Effectiveness between Inpatient and Home-Based Post-Acute Care Models for Stroke Rehabilitation in Taiwan.

Stroke rehabilitation focuses on alleviating post-stroke disability. Post-acute care (PAC) offers an intensive rehabilitative program as transitional care following acute stroke. A novel home-based PAC program has been initiated in Taiwan since 2019. Our study aimed to compare the current inpatient PAC model with a novel home-based PAC model in cost-effectiveness and functional recovery for stroke patients in Taiwan. One hundred ninety-seven stroke patients eligible for the PAC program were divided into two different health interventional groups. One received rehabilitation during hospitalization, and the other received rehabilitation by therapists at home. To evaluate the health economics, we assessed the total medical expenditure on rehabilitation using the health system of Taiwan national health insurance and performed cost-effectiveness analyses using improvements of daily activity in stroke patients based on the Barthel index (BI). Total rehabilitative duration and functional recovery were also documented. The total rehabilitative cost was cheaper in the home-based PAC group (p < 0.001), and the cost-effectiveness is USD 152.474 ± USD 164.661 in the inpatient group, and USD 48.184 ± USD 35.018 in the home group (p < 0.001). Lesser rehabilitative hours per 1-point increase of BI score was noted in the home-PAC group with similar improvements in daily activities, life quality and nutrition in both groups. Home-based PAC is more cost-effective than inpatient PAC for stroke rehabilitation.

Predicting the Need for Post-Acute Inpatient Rehabilitation of Acute Stroke Patients in Taiwan

To identify predictors of admission to post-acute inpatient rehabilitation settings following acute care for stroke patients in Taiwan and develop referral criteria.

Post-acute care regains quality of life among middle-aged and older stroke patients in Taiwan

ObjectiveThis study aims to evaluate health-related quality of life (HRQoL) of middle-aged and older stroke patients receiving the stroke post care (PAC) program and to identify possible predictors. Design, setting and participantsThis is a retrospective cohort study. Demographic characteristics and functional outcomes (modified Rankin Scale, Barthel Index, Mini-Mental State Examination, and the Concise Chinese Aphasia Test) were collected at enrollment. EQ-5D HRQoL questionnaires were administered at the beginning and the end of PAC, and health state utilities were compared. ResultsThe EQ-5D utilities of stroke patients aged 75–84 years and 85 years or above were estimated to be 0.091 and 0.159 lower than those aged less than 50 years. A decrease of the utility by 0.075 was observed among patients with the prior history of stroke. The EQ-5D utilities of patients having Barthel Index of 21–40, 41–60, and 61–100 were 0.1432, 0.1568, and 0.1387 higher than those having Barthel Index of 0–20, respectively. For patients reporting extreme problems in self-care or any dimension of EQ-5D questionnaires prior to PAC, increases in utilities by 0.0733 and 0.2875 were noted. The EQ-5D utility of PAC service duration rose by 0.0733 per one incremental day. Conclusions and implicationsThis study provides vital evidence regarding time-varying benefits of PAC services to HRQoL of stroke patients and to identify multiple predictors of HRQoL among stroke patients receiving PAC services. This study thus could serve as good reference to enhance quality of PAC services among stroke patients.

The Conditions Under Which Piracetam Is Used and the Factors That Can Improve National Institute of Health Stroke Scale Score in Ischemic Stroke Patients and the Importance of Previously Unnoticed Factors From a Hospital-Based Observational Study in Taiwan.

This study aimed to explore the associations of piracetam use and the clinical characteristics of NIHSS (National Institute of Health Stroke Scale) changes—the importance of which, as prognosis related factors, was previously unnoticed—and analyze the associations of piracetem with NIHSS changes by stratifying clinical characteristics. This observational retrospective study was conducted by enrolling patients based on 2483 stroke registration data cohorts from a 1200-bed regional Tungs’ Taichung MetroHarbor Hospital, located in central Taiwan from 1 January 1 2011 to 31 December 2015. Patients were excluded if they had intravenous a thrombolytic agent within 3 hours of symptoms onset (n = 49), incomplete or erroneous NIHSS scores (n = 953), or transient ischemia stroke (n = 130). Logistic regression model was applied for associating piracetam treatment and clinical characteristics with NIHSS score changes between admission and discharge, and subgroup analysis to assess the conditions under which piracetam can be used. Multivariate analysis revealed NIHSS scores improvement in atrial fibrillation, large-artery atherosclerosis, underweight, current smoker, ex-smoker, and piracetam. Subgroup analysis showed piracetam is beneficial in the following: age ≥75 years olds, males, those of normal weight, those who are obese, ex-smokers, those with hypertension, dyslipidemia, those without diabetes mellitus, nor atrial fibrillation. The selection of the conditions under which piracetam treatment should be given, and clinical characteristics, is important for NIHSS improvement of ischemic stroke patients in Taiwan.

Prevalence and clinical characteristics of stroke patients with p.R544C NOTCH3 mutation in Taiwan.

ObjectiveFeatures of cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy ( CADASIL) caused by NOTCH3 mutations vary between ethnicities and regions. In Taiwan, more than 70% of CADASIL patients carry the mutation hot spot of p.R544C. We investigated the prevalence of NOTCH3 p.R544C mutation in stroke patients in Taiwan.MethodsThis prospective, multicenter study recruited acute stroke patients within 10 days of symptom onset. The p.R544C mutation was identified by polymerase chain reaction with confronting two‐pair primers and sequencing. Clinical parameters, vascular risk factors, stroke subtypes, and stroke outcomes were analyzed.ResultsOf the 1970 stroke patients (mean age 61.1 ± 13.6 years, male 69.5%) included, 1705 (86.5%) had ischemic stroke and 265 (13.5%) had intracerebral hemorrhage. The prevalence of p.R544C in the study population was 2.8% (95% confidence interval [CI] = 2.1–3.5%). The prevalence was highest in patients with small vessel occlusion type of ischemic stroke (5.6%), followed by intracerebral hemorrhage (5.3%), and infarct of undetermined etiology (2.7%), and was low in patients with cardioembolism (0.8%) and large artery atherosclerosis (0.7%). All p.R544C patients with intracerebral hemorrhage were nonlobar hemorrhage. Sibling history of stroke (odds ratio [OR] = 4.50, 95% CI = 1.67–12.14 in ischemic stroke; OR = 6.03, 95% CI = 1.03–35.47 in intracerebral hemorrhage, respectively) and small vessel occlusion (OR, 4.03, 95% CI, 1.26–12.92) were significantly associated with p.R544C.Interpretationp.R544C NOTCH3 mutation is underdiagnosed in stroke patients in Taiwan, especially in those with small vessel occlusion and sibling history of stroke.

Increase of Meningitis Risk in Stroke Patients in Taiwan.

The blood-brain barrier (BBB) not only provides a physical obstruction but also recruits and activates neutrophils in cases of infection. Hemorrhagic or ischemic stroke reportedly induces the disruption of the BBB. However, few studies have reported a correlation between the incidence of meningitis in patients with a history of stroke. This study tested the hypothesis that patients with a history of stroke may be more vulnerable to meningitis. Stroke and age-matched comparison (n = 29,436 and 87,951, respectively) cohorts were recruited from the Taiwan National Health Insurance database (2000-2011). Correlations between the two cohorts were evaluated by Cox proportional hazard regression model, Kaplan-Meier curve, and log-rank tests. The incidence of meningitis was higher in the stroke cohort compared to that in the comparison cohort [hazard ratio (HR), 2.89; 95% confidence interval (CI), 2.23-3.74, p < 0.001]. After adjusting for age, sex, and comorbidities, the estimated HR in the stroke cohort was 2.55-fold higher than that in the comparison cohort (CI, 1.94-3.37; p < 0.001). Notably, patients who had experienced hemorrhagic stroke had a higher incidence rate of meningitis than those with a history of ischemic stroke, except for patients older than 75 years (incidence rates in hemorrhagic/ischemic stroke patients, 3.14/1.48 in patients younger than 45 years, 1.52/0.41 in 45- to 64-year group, 1.15/0.90 in 65- to 74-year group, 0.74/0.93 in patients older than 75 years). Moreover, stroke patients who had undergone head surgery had the highest meningitis risk (adjusted HR, 8.66; 95% CI, 5.55-13.5; p < 0.001) followed by stroke patients who had not undergone head surgery (adjusted HR, 2.11; 95% CI, 1.57-2.82; p < 0.001). Our results indicated that stroke patients have higher risks of meningitis. Compromised BBB integrity in stroke patients may lead to increased vulnerability to infectious pathogens. In summary, our study provided new evidence of the clinical relationship between stroke and meningitis, and our findings suggest the need for precautions to prevent meningitis in stroke patients.

Registry-based stroke research in Taiwan: past and future.

Stroke registries are observational databases focusing on the clinical information and outcomes of stroke patients. They play an important role in the cycle of quality improvement. Registry data are collected from real-world experiences of stroke care and are suitable for measuring quality of care. By exposing inadequacies in performance measures of stroke care, research from stroke registries has changed how we manage stroke patients in Taiwan. With the success of various quality improvement campaigns, mortality from stroke and recurrence of stroke have decreased in the past decade. After the implementation of a nationwide stroke registry, researchers have been creatively expanding how they use and collect registry data for research. Through the use of the nationwide stroke registry as a common data model, researchers from many hospitals have built their own stroke registries with extended data elements to meet the needs of research. In collaboration with information technology professionals, stroke registry systems have changed from web-based, manual submission systems to automated fill-in systems in some hospitals. Furthermore, record linkage between stroke registries and administrative claims databases or other existing databases has widened the utility of registry data in research. Using stroke registry data as the reference standard, researchers have validated several algorithms for ascertaining the diagnosis of stroke and its risk factors from claims data, and have also developed a claims-based index to estimate stroke severity. By making better use of registry data, we believe that we will provide better care to patients with stroke.

An Investigation of the Use of Traditional Chinese Medicine and Complementary and Alternative Medicine in Stroke Patients.

This study aimed to investigate the use of traditional Chinese medicine and complementary and alternative medicine in stroke patients in Taiwan. Chinese herbal medicine, massage, acupuncture, natural products, and exercise were widely used among stroke patients. Integrating safe and effective traditional Chinese medicine and complementary and alternative medicine into conventional therapies is suggested.

Three years of the nationwide post-acute stroke care program in Taiwan

Prolonged hospital stay and readmission are prevalent problems for stroke patients in Taiwan after the acute stage, partly due to the unmet need of post-acute care. In March 2014, Taiwan's National Health Insurance Administration launched a nationwide Post-Acute Care-CerebroVascular Disease (PAC-CVD) program. The Taiwan Stroke Society, coordinating 11 allied disciplines, took responsibility for the preparation and implementation of the program. As of June 2016, 6839 consecutive stroke patients were enrolled. On discharge from the PAC program, the functional status had improved in 87.5% of patients, with a significant decrease in the mean modified Rankin Scale score from 3.7 to 3.0. The rates of readmission and mortality in the PAC group were also lower than in the control group. In conclusion, the Taiwan's PAC-CVD program is an innovative and essentially effective national program of post-acute stroke care. We believe such experience should be helpful for policy makers of stroke care worldwide.

Enhanced Risk for Specific Somatic Myeloproliferative Neoplastic Mutations in Patients with Stroke.

Somatic mutations of Janus kinase 2 (JAK2V617F), calreticulin (CALR), and myeloproliferative leukemia virus oncogene (MPL) are the major clonal molecules that drive the pathogenesis of myeloproliferative neoplasms (MPN). It is well recognized that MPN patients carry an excessive risk of thrombohemorrhagic complications. However, little is known about the prevalence of these clonal markers in patients with cerebral vascular disease. To address this issue, 153 consecutive stroke patients in Taiwan were enrolled in the study. Allele-specific PCR (AS-PCR), real-time AS-PCR, and Illumina paired-end sequencing were employed to detect the presence of MPL, JAK2V617F, and CALR exon 9 mutations, respectively. JAK2V617F mutation was detectable in 13 samples (8.5%), but the allele burdens (AB) were greater than 1% in only six (3.9%) of them. Compared to JAK2-unmutated patients, those with JAK2V617F AB &gt; 1% had significantly higher white blood count (p = 0.01), although four of the six did not exhibit MPN phenotypes. Two patients had a heterozygous CALR exon9 mutation locating outside the coding region and did not alter the amino acid sequence of this protein. On the other hand, there were no patients carrying the MPL mutations. Using patient age, baseline hemogram, and stroke-relevant risk factors, we developed a predictive model that could successfully identify stroke patients at risk of carrying clonal JAK2V617F mutation. The prevalence of JAK2V617F mutation in stroke patients was higher than that seen in general population. Based on our newly developed probability stratification model, genotyping of JAK2V617F mutation in selected patients with stroke might be warranted.

Impact of MCA stenosis on the early outcome in acute ischemic stroke patients.

BackgroundAsians have higher frequency of intracranial arterial stenosis. The present study aimed to compare the clinical features and outcomes of ischemic stroke patients with and without middle cerebral artery (MCA) stenosis, assessed by transcranial sonography (TCS), based on the Taiwan Stroke Registry (TSR).MethodsPatients with acute ischemic stroke or transient ischemic attack registered in the TSR, and received both carotid duplex and TCS assessment were categorized into those with stenosis (≥50%) and without (<50%) in the extracranial internal carotid artery (ICA) and MCA, respectively. Logistic regression analysis, Kaplan-Meier method and Cox proportional hazard model were applied to assess relevant variables between groups.ResultsOf 6003 patients, 23.3% had MCA stenosis, 10.1% ICA stenosis, and 3.9% both MCA and ICA stenosis. Patients with MCA stenosis had greater initial NIHSS, higher likelihood of stroke-in-evolution, and more severe disability than those without (all p<0.001). Patients with MCA stenosis had higher prevalence of hypertension, diabetes and hypercholesterolemia. Patients with combined MCA and extracranial ICA stenosis had even higher NIHSS, worse functional outcome, higher risk of stroke recurrence or death (hazard ratio, 2.204; 95% confidence intervals, 1.440–3.374; p<0.001) at 3 months after stroke than those without MCA stenosis.ConclusionsIn conclusion, MCA stenosis was more prevalent than extracranial ICA stenosis in ischemic stroke patients in Taiwan. Patients with MCA stenosis, especially combined extracranial ICA stenosis, had more severe neurological deficit and worse outcome.

A Population-Based Cohort Study on the Ability of Acupuncture to Reduce Post-Stroke Depression.

Objective: Post-stroke depression (PSD) is common and has a negative impact on recovery. Although many stroke patients in Taiwan have used acupuncture as a supplementary treatment for reducing stroke comorbidities, little research has been done on the use of acupuncture to prevent PSD. Accordingly, our goal is to investigate whether using acupuncture after a stroke can reduce the risk of PSD. Method: This population-based cohort study examined medical claims data from a random sample of 1 million insured people registered in Taiwan. Newly diagnosed stroke patients in the period 2000–2005 were recruited in our study. All patients were followed through to the end of 2007 to determine whether they had developed symptoms of depression. A Cox proportional hazard model was used to estimate the relative risk of depression in patients after being diagnosed as having had a stroke, with a focus on the differences in those with and without acupuncture treatment. Results: A total of 8487 newly-diagnosed stroke patients were included in our study; of these, 1036 patients received acupuncture more than five times following their stroke, 1053 patients received acupuncture 1–5 times following their stroke and 6398 did not receive acupuncture. After we controlled for potential confounders (e.g., age, sex, insurance premium, residential area, type of stroke, length of hospital stay, stroke severity index, rehabilitation and major illness–related depression), we found that acupuncture after stroke significantly reduced the risk of depression, with a hazard ratio (HR) of 0.475 (95% CI, 0.389–0.580) in frequent acupuncture users and 0.718 (95% CI, 0.612–0.842) in infrequent acupuncture users, indicating that acupuncture may lower the risk of PSD by an estimated 52.5% in frequent users and 28.2% in infrequent users. Conclusions: After we controlled for potential confounders, it appears that using acupuncture after a stroke lowers the risk of depression. Additional strictly-designed randomized controlled trials are needed to better understand the specific mechanisms relating acupuncture to health outcomes.

An investigation of the use of acupuncture in stroke patients in Taiwan: a national cohort study.

BackgroundAcupuncture is considered a complementary and alternative medicine in many countries. The purpose of this study was to report the pattern of acupuncture use and associated factors in patients with stroke.MethodsWe used claims data from Taiwan’s National Health Insurance Research Database and identified 285001 new-onset stroke patients in 2000–2008 from 23 million people allover Taiwan. The use of acupuncture treatment after stroke within one year was identified. We compared sociodemographics, coexisting medical conditions, and stroke characteristics between stroke patients who did and did not receive acupuncture treatment.ResultsThe use of acupuncture in stroke patients increased from 2000 to 2008. Female gender, younger age, white-collar employee status, higher income, and residence in areas with more traditional Chinese medicine (TCM) physicians were factors associated with acupuncture use in stroke patients. Ischemic stroke (odds ratio [OR] 1.21, 95 % confidence interval [CI] 1.15–1.28), having no renal dialysis (OR 2.76, 95 % CI 2.45–3.13), receiving rehabilitation (OR 3.20, 95 % CI 3.13–3.27) and longer hospitalization (OR 1.23, 95 % CI 1.19–1.27) were also associated with acupuncture use. Stroke patients using rehabilitation services were more likely to have more acupuncture visits and a higher expenditure on acupuncture compared with stroke patients who did not receive rehabilitation services.ConclusionsThe application of acupuncture in stroke patients is well accepted and increasing in Taiwan. The use of acupuncture in stroke patients is associated with sociodemographic factors and clinical characteristics.

Patient- and Hospital-Level Determinants of Rehabilitation for In-Patient Stroke Care: An Observation Analysis.

During acute stroke care, rehabilitation usage may be influenced by patient- and hospital-related factors. We would like to identify patient- and hospital-level determinants of population-level inpatient rehabilitation usage associated with acute stroke care.From data obtained from the claim information from the National Health Insurance Administration (NHIA) in Taiwan (2009-2011), we enrolled 82,886 stroke patients with intracerebral hemorrhage and cerebral infarction from 207 hospitals. A generalized linear mixed model (GLMM) analyses with patient-level factors specified as random effects were conducted (for cross-level interactions).The rate of rehabilitation usage was 51% during acute stroke care. The hospital-related factors accounted for a significant amount of variability (intraclass correlation, 50%). Hospital type was the only significant hospital-level variable and can explain the large amount of variability (58%). Patients treated in smaller hospitals experienced few benefits of rehabilitation services, and those with surgery in a smaller hospital used fewer rehabilitation services. All patient-level variables were significant.With GLMM analyses, we identified the hospital type and its cross-level interaction, and explained a large portion of variability in rehabilitation for stroke patients in Taiwan.

Characteristics of traditional Chinese medicine usage in patients with stroke in Taiwan: A nationwide population-based study

Ethnopharmacological relevanceStroke has been the leading causes of death worldwide. Traditional Chinese medicine (TCM) has been used for stoke patients for thousands of years. This study aimed to investigate TCM usage and prescription patterns in stroke patients in Taiwan. Materials and methodsWe analyzed a random sample of one million individuals representing the 23 million enrollees selected from the National Health Insurance Research Database in Taiwan. Demographic characteristics, TCM usage, prescription patterns and mortality rate among stroke patients were analyzed. ResultsWe identified 23,816 patients who were newly diagnosed with stroke between 2001 and 2009 by their diagnostic codes (ICD-9-CM 430–438). Among them, 4302 patients had hemorrhagic stroke while 19,514 patients had ischemic stroke. Overall, 12% of the stroke patients (n=2862) were TCM users. The median interval between stroke onset to the first TCM consultation is 12.2 months. Among the TCM users, more than half (52.7%) of the patients received both Chinese herbal remedies and acupuncture/traumatology treatment. Bu-yang-huan-wu-tang and Dan-shen (Radix Salviae Miltiorrhizae; Salvia miltiorrhiza Bunge) was the most commonly prescribed Chinese herbal formula and single herb, respectively. TCM users had a higher incidence rate ratio in myalgia, myositis, fasciitis and insomnia than non-TCM users. Mental disorders such as anxiety and depression are common in both TCM and non-TCM users. Comparing with the non-TCM users, the TCM users had a lower mortality rate (adjusted hazard ratios were 0.44 in overall stroke, 0.50 in ischemic stroke and 0.25 in hemorrhagic stroke). ConclusionAdjunctive TCM use may reduce the risk of mortality rate among stroke patients. Bu-yang-huan-wu-tang and Dan-shen are the most common prescribed Chinese herbal formula and single herb for stroke patients, respectively. Future study investigating the anti-inflammatory and neuroprotective efficacy of Bu-yang-huan-wu-tang and Dan-shen in stroke is warranted.

Abstract TP321: Is Weekend Admission Associated With Increased 30-day Stroke Mortality? The Effect of Adjustment Using a Claims-Based Stroke Severity Index

Introduction: Whether weekend admission is associated with increased stroke mortality in Taiwan remains uncertain, partly because of an inadequate case-mix adjustment in other studies using an insurance claims databases. Hypothesis: Adding the 7-item claims-based stroke severity index (SSI) to a multivariate logistic regression model might alter the analysis of the effect of weekend admission on 30-day stroke mortality. Methods: We identified, in the Taiwan Longitudinal Health Insurance Database, which is linked with the National Death Registry, patients hospitalized for acute ischemic stroke between 2001 and 2013. The primary outcome was mortality 30 days post-admission. In base logistic regression models with and without the SSI, we tested the odds ratio (OR) of 30-day mortality in patient admitted on weekends using the covariates of age, sex, year of admission, Charlson’s comorbidity index, brain surgery, physician specialty and surgical volume, hospital ownership, accreditation, and patient volume. Results: We analyzed 46,007 consecutive hospitalized stroke patients (mean age: 68.8 ± 12.0 years; male: 59%), with an SSI of 7.5 ± 5.3 (range: 4.1-27.1), 23.0% were admitted on the weekend, and 4.2% died within 30 days. Patients who died within 30 days were more likely to have been admitted on a weekend (4.9% vs. 4.0%, p &lt; 0.001). Nevertheless, patients admitted on a weekend had a higher SSI than those admitted on a weekday (7.8 vs. 7.4, p &lt; 0.001). In multivariate logistic regression models, weekend admission was associated with 30-day mortality (OR: 1.22, 95% CI: 1.10-1.35) in the base model but not in the base model plus SSI (OR: 1.07, 95% CI: 0.95-1.20). Conclusions: We confirmed that, after stroke severity had been adjust by adding the SSI, weekend admission did not increase the 30-day mortality of stroke patients in Taiwan. A case-mix adjustment in comparative outcome studies of stroke patients is important when using an insurance claims database.

Predictors for total medical costs for acute hemorrhagic stroke patients transferred to the rehabilitation ward at a regional hospital in Taiwan

Background:One-third of the acute stroke patients in Taiwan receive rehabilitation. It is imperative for clinicians who care for acute stroke patients undergoing inpatient rehabilitation to identify which medical factors could be the predictors of the total medical costs.Objectives: The aim of this study was to identify the most important predictors of the total medical costs for first-time hemorrhagic stroke patients transferred to inpatient rehabilitation using a retrospective design.Methods: All data were retrospectively collected from July 2002 to June 2012 from a regional hospital in Taiwan. A stepwise multivariate linear regression analysis was used to identify the most important predictors for the total medical costs.Results: The medical records of 237 patients (137 males and 100 females) were reviewed. The mean total medical cost per patient was United States dollar (USD) 5939.5 ± 3578.5.The following were the significant predictors for the total medical costs: impaired consciousness [coefficient (B), 1075.7; 95% confidence interval (CI) = 138.5–2012.9], dysphagia [coefficient (B), 1025.8; 95% CI = 193.9–1857.8], number of surgeries [coefficient (B), 796.4; 95% CI = 316.0–1276.7], pneumonia in the neurosurgery ward [coefficient (B), 2330.1; 95% CI = 1339.5–3320.7], symptomatic urinary tract infection (UTI) in the rehabilitation ward [coefficient (B), 1138.7; 95% CI = 221.6–2055.7], and rehabilitation ward stay [coefficient (B), 64.9; 95% CI = 31.2–98.7] (R2 = 0.387).Conclusions: Our findings could help clinicians to understand that cost reduction may be achieved by minimizing complications (pneumonia and UTI) in these patients.

Young stroke patients are at high risk for subsequent end-stage renal disease: a population-based observational study

An increased incidence of end-stage renal disease (ESRD) in stroke patients has not been confirmed. The aim of this population-based study was to examine the risk of ESRD in stroke patients in Taiwan. We conducted a nationwide cohort study of 442 355 patients newly diagnosed with stroke, but without prior history of ESRD. Data were collected from Taiwan's National Health Insurance claims data during 2000-2008. Incidence and standardized incidence ratio (SIR) of ESRD were calculated using the general population of Taiwan as the reference. Among all stroke patients, 7813 (1.77%) developed ESRD with a mean follow-up of 4.11 years. The SIR for ESRD was 2.78 [95% confidence interval (CI): 2.72-2.84] among stroke patients of all ages and was 22.73 (95% CI: 20.39-25.20) for patients aged 25-44 years. Male patients with stroke had a higher risk of ESRD (SIR: 2.94, 95% CI: 2.85-3.03) among stroke patients of all ages, and it was 23.41 (95% CI: 20.46-26.36) for male patients aged 25-44 years. Increased risk of ESRD in stroke patients is confirmed in Taiwan, and male patients between ages 25 and 44 years were at higher risk of ESRD compared with their counterparts in the general population. The clinical implication of our results is to closely monitor renal function in stroke patients, particularly those of younger age.

Acceptance of disability and its predictors among stroke patients in Taiwan.

BackgroundModern medicine has increased the survival rate for stroke patients; however, the patient’s psychosocial adaptation after stroke onset may be related to the clinical outcomes. This study aimed to investigate patients’ acceptance of disability (AOD) and its predictors in stroke patients.MethodsThis cross-sectional study used a purposive sampling method to recruit 175 stroke patients from a hospital in southern Taiwan. A structured questionnaire gathered data on respondent demographics and disease characteristics, and included the Chinese version of the AOD Scale-Revised. Factors associated with AOD were examined by a multiple linear regression analysis.ResultsThe mean AOD score was 71.72, which indicated a lower level of disease acceptance (range, 32-128). Our findings showed that patients who reported no religious beliefs, shorter disease duration, recurrent stroke episodes, and poorer physical functioning also reported lower levels of disability acceptance. These factors accounted for 38.2% of the variance in AOD among participants.ConclusionsThe findings are beneficial to healthcare providers by identifying those stroke patients with predisposition of having lower disability acceptance, which could then facilitate the provision of appropriate rehabilitation interventions within six months after the diagnosis of stroke to support their adaptation process.
