Estimating the Economic Burden of Rheumatoid Arthritis in Taiwan Using the National Health Insurance Database

BACKGROUND

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and destruction of the joints.

OBJECTIVES

This research aims to estimate the economic burden of RA in Taiwan.

METHODS

The National Health Insurance Research Database (NHIRD), a claims-based dataset encompassing 99 % of Taiwan's population, was applied. We used a micro-costing approach for direct healthcare costs and indirect social costs by estimating the quantities and prices of cost categories. Direct costs included surgeries, hospitalizations, medical devices and materials, laboratory tests, and drugs. The costs and quantities of the direct economic burden were calculated based on 2011 data of NHIRD. We identified RA patients and a control cohort matched 1:4 on demographic and clinical covariates to calculate the incremental cost related to RA. Indirect costs were evaluated by missed work (absenteeism) and worker productivity (presenteeism). For the indirect burden, we estimated the rate of absenteeism and presenteeism from a patient survey. Costs were presented in US dollars (US$1 = 30 TWD).

RESULTS

A total of 41,269 RA patients were included in the database with incremental total direct cost of US$86,413,971 and indirect cost of US$138,492,987. This resulted in an average incremental direct cost of US$2050 per RA patient. Within direct costs, the largest burdens were associated with drugs (US$73,028,944), laboratory tests (US$6,132,395), and hospitalizations (US$3,208,559). For indirect costs, absenteeism costs and presenteeism costs were US$16,059,681 and US$114,291,687, respectively.

CONCLUSIONS

The economic burden of RA in Taiwan is driven by indirect healthcare costs, most notably presenteeism.

Prognostic Benefits of Carvedilol, Bisoprolol, and Metoprolol Controlled Release/Extended Release in Hemodialysis Patients with Heart Failure: A 10-Year Cohort

BACKGROUND

Heart failure is a highly prevalent cardiovascular complication among patients receiving long-term hemodialysis, but the benefits of carvedilol, bisoprolol, and metoprolol controlled release/extended release on the outcomes of these patients remain unclear. In this study, we address the use of these 3 β-blockers and their associations with mortality.

METHODS AND RESULTS

Long-term hemodialysis patients, aged ≥35 years, with new-onset heart failure and receiving various medications were identified through the use of 1999-2010 data from the Taiwan National Health Insurance Research Database. From the total of 4435 heart failure patients, we selected 1700 new users of the 3 β-blockers (study group) and 1700 nonusers (control group), by using matched cohorts according to their propensity scores, and then compared the 5-year all-cause mortality rates by using Cox proportional hazard regressions and time-dependent covariate adjustment. During 3944 person-years of follow-up, 666 (39.2%) deaths occurred within the study group, compared with 918 (54%) deaths during 2893 person-years of follow-up in the control group. The 5-year mortality rate for the study (control) group was 54.5% (70.3%); P<0.001. Adjusted hazard regression analyses revealed that the therapeutic effects of β-blockers remained significant for all-cause mortality (hazard ratio 0.80, 95% CI 0.72 to 0.90). Subgroup analyses revealed that patients in the study group receiving β-blockers plus renin-angiotensin system antagonists exhibited the lowest mortality rate, while the highest mortality rate was found among patients in the control group receiving neither β-blockers nor renin-angiotensin system antagonists.

CONCLUSIONS

This study demonstrates that the 3 β-blockers were associated with improved survival in long-term hemodialysis patients with heart failure.

Is drug discontinuation risk of adalimumab compared with etanercept affected by concomitant methotrexate dose in patients with rheumatoid arthritis?

OBJECTIVE

To compare drug discontinuation risk between adalimumab (ADA) and etanercept (ETN) treatment among anti-tumor necrosis factor (anti-TNF)-naïve rheumatoid arthritis (RA) patients, in particular the influence of concomitant dose of methotrexate (MTX).

METHODS

This retrospective nationwide population-based cohort study identified 4,592 anti-TNF-naïve RA patients in whom ETN (n=2,609) or ADA (n=1,983) was initiated using National Health Insurance claims data. After adjustment for prior medication, concomitant medication, and baseline demographic data, the relative risk of drug discontinuation in ADA users compared with ETN users was quantified by calculating adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) using Cox proportional hazard regression analyses, stratified by the follow-up time (≤1 year, >1 year) and/or concomitant MTX dose (≤10 mg/wk, >10 mg/wk).

RESULTS

ADA users had a higher risk of drug discontinuation compared with ETN users during the first year of follow-up (aHR, 1.13; 95% CI, 1.01-1.27), but not during all treatment periods (aHR, 1.06; 95% CI, 0.98-1.16) or after 1 year (aHR, 0.99; 95% CI, 0.87-1.13). However, ADA users had a significantly higher risk of drug discontinuation compared with ETN users among patients on concomitant MTX >10 mg/wk during all treatment periods (aHR, 1.27; 95% CI, 1.10-1.47), during the first year of follow-up (aHR, 1.48; 95% CI, 1.22-1.78), or after 1 year (aHR, 1.42; 95% CI, 1.06-1.90), but not among patients on concomitant MTX 0-10 mg/wk.

CONCLUSION

This population-based cohort study demonstrated a modification effect of concomitant MTX dose on the relative risk of anti-TNF discontinuation for ADA compared with ETN among anti-TNF-naïve RA patients. However, the lack of exact cause of anti-TNF discontinuation limited causal inference of such a concomitant MTX dose-related modification effect.

Chronic otitis media surgery and re-operation risk factor analysis: A nationwide retrospective cohort study of 18 895 patients

CONCLUSION

Patients with risk factors including younger age, mastoiditis, external ear disease, treatment by older surgeons, and concomitant mastoidectomy should receive detailed management to minimize the probability of re-operation for chronic otitis media (COM).

OBJECTIVES

Although COM remains a common ear disease requiring surgical intervention, its re-operation risks are less well-documented. This study aimed to compare patients with COM who underwent re-operation and those patients with no re-operation, and identify the risks of re-operation.

METHOD

This retrospective cohort study analyzed the trend of COM surgery from 1999-2009, and identified the re-operation risks of 18 895 patients with COM who underwent surgery from 2002-2006 using the National Health Insurance Research Database in Taiwan.

RESULTS

Among the study population, 129 patients underwent revision surgery during a 5.5 ± 1.5 year follow-up period. A univariate logistic regression analysis showed that the re-operation rate was significantly higher in patients under 18 years of age, those with mastoiditis, disorders of external ear, treatment by surgeons of 50-64 years of age, use of a very high volume surgeon, and combined surgery with mastoidectomy. A multivariate analysis further limited the re-operation risk factors to younger patients, those with mastoiditis, external ear disorders, treatment by older surgeons, and concomitant mastoidectomy.

Difference in strong opioid prescription among different cancer and care providers in advanced cancer patients in Taiwan: Analysis using national health insurance database

55

Background: Pain assessment and management had been adopted as an important criteria in hospital accreditation in Taiwan. National health insurance database may help to determine factors influencing patterns of strong opioid use in advanced cancer patients in their final 12 months of life. Methods: Cancer patients who died from cancer during 2008-2011 were included in the analysis. Data in prescription of strong opioids during their last 12 months of life were collected and analyzed using National Health Insurance Research Database (NHIRD). Patient’s characteristics, such as cancer types, birthdate and gender, as well as information on the provider’s characteristics, such as specialty, gender and age of the physician, the ownership and level of accreditation of the hospital, and the level of urbanization of the hospital where it is located, were also retrieved and included as the controlled variables in the analysis. Results: Of the 162,679 cancer deaths, 57,578 were prescribed strong opioids in their last year of life (35.4 percent). Strong opioid prescription steadily decreased with the corresponding increase in patient age. Besides there are difference in different cancer types. Association with prescription prevalence has also been noted among physician characteristics such as subspecialty, gender and age, as well among hospital characteristics, such as public vs private and accreditation level. Conclusions: There are significant difference in strong opioids prescription among different care providers for advanced cancer patients. Information from this study can guide further efforts in improving supportive care and education for advanced cancer care providers.

Measuring Preferences for a Diabetes Pay-for-Performance for Patient (P4P4P) Program using a Discrete Choice Experiment

OBJECTIVE

To elicit a patient's willingness to participate in a diabetes pay-for-performance for patient (P4P4P) program using a discrete choice experiment method.

METHODS

The survey was conducted in March 2013. Our sample was drawn from patients with diabetes at five hospitals in Taiwan (International Classification of Diseases, Ninth Revision, Clinical Modification code 250). The sample size was 838 patients. The discrete choice experiment questionnaire included the attributes monthly cash rewards, exercise time, diet control, and program duration. We estimated a bivariate probit model to derive willingness-to-accept levels after accounting for the characteristics (e.g., severity and comorbidity) of patients with diabetes.

RESULTS

The preferred program was a 3-year program involving 30 minutes of exercise per day and flexible diet control. Offering an incentive of approximately US $67 in cash per month appears to increase the likelihood that patients with diabetes will participate in the preferred P4P4P program by approximately 50%.

CONCLUSIONS

Patients with more disadvantageous characteristics (e.g., elderly, low income, greater comorbidity, and severity) could have less to gain from participating in the program and thus require a higher monetary incentive to compensate for the disutility caused by participating in the program's activities. Our result demonstrates that a modest financial incentive could increase the likelihood of program participation after accounting for the attributes of the P4P4P program and patients' characteristics.

All optical mode controllable Er-doped random fiber laser with distributed Bragg gratings

An all-optical method to control the lasing modes of Er-doped random fiber lasers (RFLs) is proposed and demonstrated. In the RFL, an Er-doped fiber (EDF) recoded with randomly separated fiber Bragg gratings (FBG) is used as the gain medium and randomly distributed reflectors, as well as the controllable element. By combining random feedback of the FBG array and Fresnel feedback of a cleaved fiber end, multi-mode coherent random lasing is obtained with a threshold of 14 mW and power efficiency of 14.4%. Moreover, a laterally-injected control light is used to induce local gain perturbation, providing additional gain for certain random resonance modes. As a result, active mode selection of the RFL is realized by changing locations of the laser cavity that is exposed to the control light.

Gout and the risk of dementia: a nationwide population-based cohort study

Introduction

Uric acid was proposed to have anti-oxidant property and possible neuroprotective effects. We examined the association between gout and dementia with population database.

Methods

The study utilized the claims data from the nationwide representative sample of Taiwan National Health Insurance Research Database (NHIRD). We ascertained patients with gout and dementia covering vascular and non-vascular (including Alzheimer’s) subtypes using International Classification of Diseases Ninth Revision, Clinical Modification (ICD9-CM) codes. A control group matched on sex, age, and index date of gout patients was randomly sampled with a ratio of 1:4 from the same database for comparison.

Results

From 2002 to 2008, 28,769 gout patients who were older than 50 years old were identified, and 114,742 control patients was matched into the study. During follow-up, 7,119 patients developed dementia (1,214 with gout, and 5,905 without gout). After adjusting for age, sex, and relevant comorbidities, a Cox regression analysis showed that gout patients had a lower risk of developing non-vascular dementia (hazard ratio (HR): 0.77; 95% confidence interval (CI): 0.72 - 0.83; p < 0.001) and vascular dementia (HR: 0.76; 95% CI: 0.65 - 0.88; p < 0.001).

Conclusions

Patients with gout have a lower risk of developing dementia. This phenomenon exists for both non-vascular and vascular types of dementia.

Increased risk of Bell palsy in patients with migraine: a nationwide cohort study

OBJECTIVE

To evaluate the association between migraine and Bell palsy and to examine the effects of age, sex, migraine subtype, and comorbid risk factors for Bell palsy.

METHODS

This nationwide cohort study was conducted using data from the Taiwan National Health Insurance Research Database. Subjects aged 18 years or older with neurologist-diagnosed migraine from 2005 to 2009 were included. A nonheadache age- and propensity score-matched control cohort was selected for comparison. All subjects were followed until the end of 2010, death, or the occurrence of a Bell palsy event. Cox proportional hazards regression was used to calculate the adjusted hazard ratios and 95% confidence intervals to compare the risk of Bell palsy between groups.

RESULTS

Both cohorts (n = 136,704 each) were followed for a mean of 3.2 years. During the follow-up period, 671 patients (424,372 person-years) in the migraine cohort and 365 matched control subjects (438,677 person-years) were newly diagnosed with Bell palsy (incidence rates, 158.1 and 83.2/100,000 person-years, respectively). The adjusted hazard ratio for Bell palsy was 1.91 (95% confidence interval, 1.68-2.17; p < 0.001). The association between migraine and Bell palsy remained significant in sensitivity analyses, and tests of interaction failed to reach significance in all subgroup analyses.

CONCLUSION

Migraine is a previously unidentified risk factor for Bell palsy. The association between these 2 conditions suggests a linked disease mechanism, which is worthy of further exploration.

Increased risk of urinary calculi in patients with migraine: a nationwide cohort study

OBJECTIVE

Whether migraine is associated with urinary calculi is an unresolved issue, although topiramate, a migraine-preventive agent, is known to contribute to this complication. This study investigates the association between migraine and the risk of urinary calculi.

METHODS

We identified a total of 147,399 patients aged ≥18 years with migraine diagnoses recorded in the Taiwan National Health Insurance Research Database between 2005 and 2009. Each patient was randomly matched with one individual without headache using propensity scores. All participants were followed from the date of enrollment until urinary calculi development, death, or the end of 2010.

RESULTS

The risk of urinary calculi was greater in the migraine than the control cohort (adjusted hazard ratio (aHR), 1.58; 95% confidence interval (CI), 1.52-1.63; p < 0.001, irrespective of the influence of topiramate. The risk was higher in younger and female patients. The magnitude of the risk was proportional to the annual frequency of clinic visits for headache (≥6 vs. <3, aHR = 1.11; 95% CI, 1.04-1.17; p = 0.002), but did not differ between migraine patients with and without aura.

CONCLUSIONS

Our study showed migraine was associated with an increased risk of urinary calculi, independent of topiramate use. A higher frequency of clinic visits was associated with a greater risk.

Infection risk in patients with rheumatoid arthritis treated with etanercept or adalimumab

OBJECTIVES

To compare the risk of infection for rheumatoid arthritis (RA) patients who took etanercept or adalimumab medication in a nationwide population.

METHODS

RA patients who took etanercept or adalimumab were identified in the Taiwan's National Health Insurance Research Database. The composite outcome of serious infections, including hospitalization for infection, reception of an antimicrobial injection, and tuberculosis were followed for 365 days. A Kaplan-Meier survival curve with a log-rank test and Cox proportional hazards regression were used to compare risks of infection between the two cohorts of tumor necrosis factor (TNF)-α antagonists users. Hazard ratios (HRs) were obtained and adjusted with propensity scores and clinical factors. Sensitivity analyses and subgroup analyses were also performed.

RESULTS

In total, 1660 incident etanercept users and 484 incident adalimumab users were eligible for the analysis. The unadjusted HR for infection of the etanercept users was significantly higher than that of the adalimumab users (HR: 1.93; 95% confidence interval (CI): 1.09-3.42; p=0.024). The HRs were 2.04 (95% CI: 1.14-3.65; p=0.016) and 2.02 (95% CI: 1.13-3.61; p=0.018) after adjusting for propensity scores and for propensity scores in addition to clinical factors, respectively. The subgroup analyses revealed that HRs for composite infection was significantly higher in patient subgroups of older age, female, as well as patients who did not have DM, COPD, and hospitalization history at the baseline.

CONCLUSION

In this head-to-head cohort study involving a nationwide population of patients with RA, etanercept users demonstrated a higher risk of infection than adalimumab users. Results of this study suggest the possible existence of an intra-class difference in infection risk among TNF-α antagonists.

Treatment adherence among new triptan users: a 2-year cohort study in Taiwan

BACKGROUND

The persistence of triptan use among newly prescribed users is low in the United States and European countries. However, triptan refill patterns in Asian primary care practices have not been well described.

METHODS

Data from the National Health Insurance Research Database in Taiwan were used to conduct a retrospective cohort analysis from 2005 to 2008. All participants were followed for 2 years after receiving a new triptan prescription. Refill and 2-year retention rates of newly prescribed triptans were calculated, and predictors of the first triptan refill and 2-year retention were analyzed.

RESULTS

Of the 13,951 participants with a new triptan prescription (99.9% sumatriptan), 67.4% were prescribed by a neurologist, 67.4% were prescribed at least one prophylactic agent for migraine. Of them, 34.3% adhered to the newly prescribed triptan at the first refill, 0.01% switched to another triptan, and 40.9% switched to a non-triptan acute migraine medication. The 2-year retention rate was 4.0%. The frequency of headache-related neurologic visits for 1 year before the index date, first prescription of triptan or other acute medications, first triptan prescription by a neurologist, and prophylactic use were associated with higher first refill rates. The frequency of headache-related neurologic visits 1 year before the index date and first triptan prescription by a neurologist were related to higher 2-year retention rates. Diabetes mellitus and first triptan prescription at a local medical clinic were associated with reduced probability of continued triptan use at the first refill and 2 years.

CONCLUSIONS

Similar to Western societies, the refill and 2-year retention rates were low in new users of triptans. Frequency of neurologic visits and triptan prescription by a neurologist were significant predictors of adherence.

Proton pump inhibitor-related headaches: A nationwide population-based case-crossover study in Taiwan

Background

Headaches resulting from proton pump inhibitor (PPI) use could cause discontinuation of PPI in as many as 40% of patients who experience such headaches. Previous studies focusing on acute headache risk from PPI use are rare and limited to clinical trials of a single PPI.

Objectives

To investigate the association between PPI use and headache with a nationwide population-based case-crossover study.

Methods

Records containing the first diagnosis of any headache, including migraine and tension-type headaches, were retrieved from Taiwan National Health Insurance Database (1998–2010). We compared the rates of PPI use for cases and controls during time windows of 7, 14, and 28 days. The adjusted self-matched odds ratios (ORs) and 95% confidence intervals (CIs) from a conditional logistic regression model were used to determine the association between PPI use and headache.

Results

Overall, 314,210 patients with an initial diagnosis of any headache during the study period were enrolled. The adjusted ORs for headache risk after PPI exposure were calculated for three time periods (within 7 days = 1.41, p = 0.002, 95% CI 1.14–1.74; within 14 days = 1.36, p < 0.001, 95% CI 1.16–1.59; within 28 days = 1.20, p = 0.002, 95% CI 1.07–1.35). Subgroup analyses showed female patients had an increased risk of headache. Among PPIs, lansoprazole and esomeprazole had the highest risks of headache incidence, which were similar to that of nitrates.

Conclusion

PPI usage is associated with an increased risk for acute headache. Female patients and use of lansoprazole or esomeprazole present the greatest risks of headache.

Distinct clinicopathological features and prognosis of emerging young-female breast cancer in an East Asian country: a nationwide cancer registry-based study

BACKGROUND

A rapid surge of young-female breast cancer (YFBC) has been observed in Taiwan and other East Asian countries. We recently reported that these cases of YFBC, in contrast to their Western counterparts, are predominantly luminal A subtype. YFBC in Asia may have distinct clinicopathological features and outcomes.

METHODS

Data collected prospectively by participating hospitals were retrieved from the Taiwan Cancer Database. A total of 15,881 women with newly diagnosed stage I-III breast cancer in 2002-2006 were included. The age at diagnosis was categorized into nine 5-year groups (from <30 years to ≥65 years). Clinicopathological variables and patient disease-free survival (DFS) were compared by age group.

RESULTS

The rates of stage I, estrogen receptor-positive (ER+), and progesterone receptor-positive breast cancer were higher in the younger patients (<50 years) than in the older patients (≥50 years). Univariate analysis showed that the 40-44 and 45-49 age groups were significantly associated with longer DFS than the other age groups. In the ER+ subgroup, multivariate analysis consistently showed that the 40-44 age group was significantly associated with longer DFS than the other age groups except for the 45-49 age group. In contrast, multivariate analysis of the ER-negative subgroup revealed no significant difference of DFS between the 40-44 age group and other age groups.

CONCLUSION

Emerging YFBC in Taiwan is uniquely associated with favorable pathological features and better outcomes and should not be regarded as the mirror image of its Western counterpart.

Temperature variation and the incidence of cluster headache periods: A nationwide population study

Background

Cluster headache (CH) is well known to show a seasonal predilection; however, the impact of temperature and other meteorological factors on cluster periods (or bouts) has not been established.

Methods

This nationwide survey included 758 patients with episodic CH retrieved from the Taiwan National Health Insurance Research Database from 2005 to 2009. Corresponding meteorological recordings were obtained from the Central Weather Bureau. A case-crossover study design was used to investigate the association between cluster periods and meteorological factors.

Results

A total of 2452 episodes of cluster periods were recorded. The cluster periods were most frequent in the autumn and least frequent in the winter. Seasonal changes from winter to spring and from autumn to winter also increased the frequency of cluster periods. The risk of cluster periods increased when there was a higher mean temperature on event days (odds ratio (OR), 1.014, 95% confidence interval (CI), 1.005–1.023, p = 0.003) or within seven to 56 days. Either an increase or a decrease in temperature (0.05℃/day) following a warm period (mean temperature ≥26℃) was associated with the onset of cluster periods. In contrast, a greater increase in temperature (0.15℃/day) following a cold period (mean temperature < 21℃) was needed to evoke cluster periods. No such associations were found following moderate periods (21℃ ≤mean temperature <26℃).

Discussion

Our study shows that temperature is associated with precipitating or priming cluster periods. The influence depends on the temperature of the preceding periods.

Short-term use of serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding

OBJECTIVE

The association between selective serotonin receptor inhibitors (SSRIs) and risk of upper gastrointestinal bleeding remains controversial. Previous studies have generally evaluated the issue for approximately 3 months, even though the SSRI-mediated inhibition of platelet serotonin concentrations occurs within 7-14 days. The authors explored the risk of upper gastrointestinal bleeding after short-term SSRI exposure by a case-crossover design.

METHOD

The records of psychiatric inpatients with upper gastrointestinal bleeding were retrieved from the Taiwan National Health Insurance Database (1998-2009). Rates of antidepressant use were compared for case and control periods with time windows of 7, 14, and 28 days. The adjusted self-matched odds ratios from a conditional logistic regression model were used to determine the association between SSRI use and upper gastrointestinal bleeding.

RESULTS

A total of 5,377 patients with upper gastrointestinal bleeding were enrolled. The adjusted odds ratio for the risk of upper gastrointestinal bleeding after SSRI exposure was 1.67 (95% CI=1.23-2.26) for the 7-day window, 1.84 (95% CI=1.42-2.40) for the 14-day window, and 1.67 (95% CI=1.34-2.08) for the 28-day window. SSRIs with high and intermediate, but not low, affinity for serotonin transporter were associated with upper gastrointestinal bleeding. An elevated risk of upper gastrointestinal bleeding after SSRI exposure was seen in male but not female patients.

CONCLUSIONS

Short-term SSRI use (7-28 days) is significantly associated with upper gastrointestinal bleeding. Gender differences may exist in the relationship between SSRI use and upper gastrointestinal bleeding. Physicians should carefully monitor signs of upper gastrointestinal bleeding even after short-term exposure to SSRIs, as is done with nonsteroidal anti-inflammatory drugs and aspirin.

Renin-angiotensin system blockade in heart failure patients on long-term haemodialysis in Taiwan

AIMS

Heart failure is among the most frequent complications of patients on long-term haemodialysis. The benefits of renin-angiotensin system (RAS) blockade on the outcomes of these patients have yet to be determined.

METHODS AND RESULTS

We conducted a nationwide observational study using data from the Taiwan National Health Insurance claims database, between 1999 and 2010. We enrolled patients aged ≥35 years with new-onset heart failure [diagnosed by International Classification of Diseases, 9th revision, clinical modification (ICD-9-CM) codes] under treatment with medications. New users of a RAS blocker (RASB; i.e., an ACE inhibitor or an ARB used as monotherapy or dual therapy) were selected to compare with non-RASB users. We used Cox proportional hazards regression with and without propensity score adjustment to compare the risk of 3-year all-cause and cardiovascular mortality. Stratified analyses and RASB therapy duration as a time-dependent covariate were also performed. In all, 4771 were treated with an RASB (n = 3024) or without an RASB (n = 1747). RASB users had a higher prevalence of hypertension and diabetes, and a higher number of hospitalization. Among RASB users, 1148 deaths (38.0%) occurred during 5272 person-years of follow-up compared with 734 deaths (42.0%) among non-RASB users during 2683 person-years of follow-up. Three-year mortality rates were 45.4% and 49.1% for patients receiving and those not receiving an RASB, respectively (log-rank test, P < 0.001). Adjusted hazard analysis revealed that RASB therapeutic effects remained significant on all-cause [hazard ratio (HR) 0.8; 95% confidence interval (CI) 0.72-0.89; P < 0.001] and cardiovascular mortality (HR 0.76; 95% CI 0.64-0.90; P < 0.01).

CONCLUSIONS

RASB therapy reduced all-cause and cardiovascular mortality in heart failure patients on long-term haemodialysis.
