Population-attributable fraction of psychiatric and physical disorders for suicide among older adults in Taiwan.

BACKGROUND: This study aimed to estimate the population-attributable fraction (PAF) of psychiatric and physical disorders for suicide among older adults, focusing on sex- and age-specific factors. METHODS: Data from Taiwan's National Health Insurance Research Data and National Death Registry included 9136 cases of suicide in individuals aged 65+, with 89,439 matched controls. Physical and psychiatric disorders were identified through diagnostic records. Conditional logistic regression assessed risk factors, and PAF was calculated using disorder prevalence and adjusted odds ratios. RESULTS: Major suicide risk factors among older adults were depressive disorders, anxiety disorders, and sleep disorders. Physical disorders like hypertension, peptic ulcers, and cancer also showed significant PAF values. The combined PAF of physical disorders equaled that of psychiatric disorders. Psychiatric disorders had a greater impact on women and the youngest-old adults, while physical disorders had a higher contribution among men, middle-old adults, and oldest-old adults. LIMITATIONS: Relying solely on claim data to identify psychiatric and physical disorders may underestimate their prevalence and associations with suicide due to unrecorded cases of individuals not seeking help and the absence of key risk factors like social isolation and family support. CONCLUSIONS: This study identifies preventable or treatable risk factors for older adult suicide, emphasizing the need to target specific psychiatric and physical disorders in suicide prevention efforts while taking into account sex- and age-specific considerations. It also underscores the importance of establishing social welfare support systems to address the unique challenges older adults face.

Cost and effectiveness analyses of the anti-osteoporosis medication in patients with hip fracture in Taiwan: A population-based national claims database analysis.

BACKGROUND: Real-world cost and effectiveness analyses of the anti-osteoporosis medications (AOM) using a nationwide database in Asia were limited. The aim of this study was to evaluate the cost and effectiveness of AOMs therapy under the reimbursement of National Health Insurance in Taiwan. METHODS: Using Taiwan's National Health Insurance Research Database, patients who had hospitalization due to incident hip fractures with related operation between 2008 and 2017 were identified as our study population. Patients who initiated AOMs within 1 year post incident hip fracture were matched with those did not according to the propensity score. The direct medical cost and subsequent fracture within three years were estimated. Statistically significant differences of risk for subsequent fracture between the AOM and non-AOM groups were estimated using the COX proportional hazards model. All costs were presented as New Taiwan Dollars (NTD). RESULTS: There were 27,357 new hip fracture patients who initiated AOMs, and 76% of them were women with a mean age of 77.7 years. Among patients ages ≥70 who encountered hip fractures, those who initiated AOMs experienced fewer non-vertebral fractures (HR = 1.07 (1.02-1.13), p = 0.0114 for those ages 70-79 years old; HR = 1.11 (1.06-1.17), p < 0.0001 for those ages ≥80 years) and mortality (HR = 1.18 (1.14-1.22), p < 0.0001 for those ages 70-79; HR = 1.20 (1.16-1.23), p < 0.0001) within 3 years post incident fracture; meanwhile, consuming fewer medical resources in the national insurance healthcare system. (Increment cost = -16011.2 NTD, p = 0.0248 for those ages 70-79; Increment cost = -17257.9 NTD, p = 0.0032 for those ages ≥80 years) CONCLUSION: Overall, under Taiwan's national health insurance, the use of AOMs is cost-saving, especially in the population aged ≥70 years. The finding of this research was valuable for policymakers in considering healthcare policy promotion and resource allocation in the future.

Long-term outcomes of the pay-for-performance program for patients with young-onset (20-40 years of age) type 2 diabetes.

AIMS: To investigate the long-term outcomes of Pay-for-Performance (P4P) care in patients with young-onset (20-40 years of age) diabetes (YOD). METHODS: We recruited 3088 pairs of propensity-score matched patients with and without P4P care from the National Health Insurance Research Database between January 1, 2001, and December 31, 2017. The study used a multivariable Cox regression model to compare the risks of mortality, hospitalization for cardiovascular events, and major microvascular outcomes in YOD patients with and without P4P care. RESULTS: The multivariable-adjusted model showed that patients with P4P care had significantly lower risks of mortality (aHR 0.31, 95% CI 0.25-0.38) and hospitalization for cardiovascular events (aHR 0.63, 95% CI 0.5-0.79) but a significantly higher risk of major microvascular outcomes (aHR 1.31, 95% CI 1.07-1.6). Patients with a longer cumulative duration of P4P and complete P4P care showed further lower risks of mortality, hospitalization for cardiovascular events, and major microvascular outcomes than those without P4P care. CONCLUSIONS: This nationwide cohort study showed that young-onset diabetes patients with P4P care had lower risks of death and cardiovascular events but a higher risk of major microvascular outcomes. However, patients with a longer duration of P4P care showed lower risks of these outcomes.

Impact of chronic hepatitis on cardiovascular events among type 2 diabetes patients in Taiwan pay-for-performance program.

To investigate the impact of chronic hepatitis on cardiovascular events in patients with type 2 diabetes mellitus (T2DM). This nationwide retrospective cohort study included 152,709 adult patients (> 20 years) with T2DM enrolled in the National Health Insurance Diabetes Pay-for-Performance Program from 2008 to 2010 and followed up until the end of 2017. Patients were categorized into groups with hepatitis B, hepatitis C, fatty liver disease, and patients without chronic hepatitis. The incidence of cardiovascular events in patients with T2DM and hepatitis C (79.9/1000 person-years) was higher than that in patients with diabetes combined with other chronic hepatitis, or without chronic hepatitis. After adjusting for confounding factors, T2DM with fatty liver (adjusted hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 1.07-1.13) and hepatitis C (adjusted HR: 1.09; 95% CI: 1.03-1.12) demonstrated a significantly higher risk of cardiovascular events. The adjusted visit-to-visit coefficient of variation of HbA1c and fasting blood glucose were associated with a high risk of cardiovascular events (HRs of the highest quartile were 1.05 and 1.12, respectively). Chronic hepatitis affects cardiovascular events in adult patients with T2DM. Glucose variability could be an independent risk factor for cardiovascular events in such patients.

Factors associated with burden among male caregivers for people with dementia.

BACKGROUND: There is a dearth of information on male dementia caregivers in Asia and, in particular, on the factors relating to caregiver burden. We aimed to identify factors that may be associated with burden among male caregivers of people with dementia (PWD). METHODS: Data were collected from a national dementia registration survey. The caregiver burden was measured with the short version of the Zarit Burden Interview (ZBI). We analyzed the correlation between ZBI scores and variables, such as demographic data of PWD and their male caregivers, caregivers' monthly income, the relationship between PWD and caregivers, the severity of dementia, physical comorbidities and activities of daily living (ADL) of PWD, and neuropsychiatric symptoms assessed by the Neuropsychiatric Inventory (NPI). RESULTS: A total of 509 PWD and their male caregivers were included. The majority of caregivers were sons (72.1%) and husbands (22.0%). Sons had higher ZBI scores than husbands (28.5 ± 15.2 vs 22.0 ± 17.0; p < 0.001). Multivariable linear regression showed that sons as caregivers (ß = 7.44, p = 0.034), ADL (ß = 0.52, p = 0.002), and NPI_severity subscore of apathy (ß = 2.74, p = 0.001) were positively associated with ZBI scores. CONCLUSION: Poor ADL and apathy in PWD and being a patient's son were associated with higher levels of burden among male dementia caregivers. Effective interventions are needed to assist male caregivers in accomplishing their caregiving role and at the same time to alleviate their caregiver burden.

Developing and Validating Risk Scores for Predicting Major Cardiovascular Events Using Population Surveys Linked with Electronic Health Insurance Records.

A risk prediction model for major cardiovascular events was developed using population survey data linked to National Health Insurance (NHI) claim data and the death registry. Another set of population survey data were used to validate the model. The model was built using the Nutrition and Health Survey in Taiwan (NAHSIT) collected from 1993-1996 and linked with 10 years of events from NHI data. Major adverse cardiovascular events (MACEs) were identified based on hospital admission or death from coronary heart disease or stroke. The Taiwanese Survey on Hypertension, Hyperglycemia, and Hyperlipidemia (TwSHHH), conducted in 2002 was used for external validation. The NAHSIT data consisted of 1658 men and 1652 women aged 35-70 years. The incidence rates for MACE per 1000 person-years were 13.77 for men and 7.76 for women. These incidence rates for the TwSHHH were 7.27 for men and 3.58 for women. The model had reasonable discrimination (C-indexes: 0.76 for men; 0.75 for women), thus can be used to predict MACE risks in the general population. NHI data can be used to identify disease statuses if the definition and algorithm are clearly defined. Precise preventive health services in Taiwan can be based on this model.

Multidisciplinary care program in pre-end-stage kidney disease from 2010 to 2018 in Taiwan.

BACKGROUND: The Taiwanese government launched a universal pay-for-performance (P4P) program in 2006 to promote multidisciplinary care for patients with stage 3b-5 chronic kidney disease (CKD). This study aimed to understand the enrollments, care processes, and outcomes of the P4P program between 2010 and 2018. METHODS: We conducted a population-based study using the Taiwan National Health Insurance Research Data. We divided the incident dialysis population into joining and not joining P4P groups based on whether patients had joined the pre-ESRD program before dialysis or not. Trends in the medications prescribed, anemia correction, vascular access preparation before dialysis initiation, and cumulative survival rate were compared. RESULTS: The program included more than 100,000 patients with late-stage CKD. Enrollment increased by almost 100% from 2010 to 2018, with increases seen in those over 75 years old (127.5%), male (96.7%), and earlier CKD stages (≥35% stage 3b in 2018). Females were more likely to stay being enrolled. The joining P4P group was prescribed more appropriate medications, such as erythropoietin-stimulating agents and statins. However, a high number of patients were still prescribed metformin (≥40%) and non-steroidal anti-inflammatory drugs (≥20%). Compared to the not joining P4P group, the patients in the P4P group had better anemia management, dialysis preparation, and post-dialysis survival. CONCLUSION: The patients in the joining P4P program group were delivered more appropriate CKD care and were associated with better survival outcomes. Polices and action plans are needed to extend the coverage of and enrollment in the P4P program.

Healthcare utilization and expenditure among individuals with end-stage kidney disease in Taiwan.

BACKGROUND/PURPOSE: The prevalence of end-stage kidney disease (ESKD) in Taiwan has been increasing in recent decades. ESKD care and medical expenditures constitute an important part of the entire healthcare system. METHODS: This study analyzed data collected from the National Health Insurance (NHI) Research Database from 2010 to 2018. RESULTS: The annual medical cost increased by approximately 4% both in the entire Taiwanese population and in its ESKD population. The total medical expenditure in the ESKD population from 2010 to 2018 increased from 48.03 to 65.65 billion reimbursement points, with dialysis treatments costing higher than non-dialysis treatments. ESKD outpatient and inpatient costs accounted for 10.4%-11.1% and 4.8%-5.6% of the entire NHI expenditure, respectively. The leading cause of inpatient costs was circulatory diseases, accounting for 29.3% of the total ESKD inpatient costs in 2018. Furthermore, percutaneous coronary intervention had the highest cost followed by simple percutaneous transluminal angioplasty. In 2018, the hemodialysis population had the highest average monthly cost of 73 thousand points per person, while the kidney transplant population had the lowest average monthly cost of 39 thousand points per person. CONCLUSION: Medical expenditure, including both inpatient and outpatient costs, of the ESKD population continued to grow from 2010 to 2018. The non-dialysis cost in the ESKD population was mainly for cardiovascular disease management and vascular access care, for which prevention will always be challenging.

Assessment of incident frailty hazard associated with depressive symptoms in a Taiwanese longitudinal study.

OBJECTIVES: To estimate the risks of depressive symptoms for developing frailty, accounting for baseline robust or pre-frailty status. DESIGN: An incident cohort study design. SETTING: Community dwellers aged 55 years and above from urban and rural areas in seven regions in Taiwan. PARTICIPANTS: A total of 2,717 participants from the Healthy Aging Longitudinal Study in Taiwan (HALST) were included. Subjects with frailty at baseline were excluded. The average follow-up period was 5.9 years. MEASUREMENTS: Depressive symptoms were measured by the 20-item Center for Epidemiological Studies Depression (CES-D) Scale. Frailty was assessed using the Fried frailty measurement. Participants were stratified by baseline robust or pre-frailty status to reduce the confounding effects of the shared criteria between depressive symptoms and frailty. Overall and stratified survival analyses were conducted to assess risks of developing frailty as a result of baseline depressive symptoms. RESULTS: One hundred individuals (3.7%) had depressive symptoms at baseline. Twenty-seven individuals (27.0%) with depressive symptoms developed frailty, whereas only 305 out of the 2,617 participants (11.7%) without depressive symptoms developed frailty during the follow-up period. After adjusting for covariates, depressive symptoms were associated with a 2.6-fold (95% CI 1.6, 4.2) increased hazard of incident frailty. The patterns of increased hazard were also observed when further stratified by baseline robust or pre-frailty status. CONCLUSIONS: Depressive symptoms increased the risk of developing frailty among the older Asian population. The impact of late-life depressive symptoms on physical health was notable. These findings also replicated results from Western populations. Future policies on geriatric public health need to focus more on treatment and intervention against geriatric depressive symptoms to prevent incident frailty among older population.

Predictors of caregiver burden in aged caregivers of demented older patients.

BACKGROUND: Dementia in the oldest-old is projected to increase exponentially as is the burden of their caregivers who may experience unique challenges and suffering. Thus, we aim to investigate which factors are associated with older caregivers' burden in caring demented outpatients in a multicenter cohort. METHODS: Patients and their caregivers, both aged ≧65 years, in the National Dementia Registry Study in Taiwan (T-NDRS) were included in this study. Caregiver burden was measured with the short version of the Zarit Burden Interview (ZBI). The correlations between the ZBI scores and characteristics of caregivers and patients, including severity of dementia, physical comorbidities, instrumental activities of daily living (IADL), neuropsychiatric symptoms assessed by the Neuropsychiatric Inventory (NPI), and family monthly income, were analyzed. RESULTS: We recruited 328 aged informal caregiver-patient dyads. The mean age of caregivers was 73.7 ± 7.0 years, with female predominance (66.8%), and the mean age of patients was 78.8 ± 6.9 years, with male predominance (61.0%). Multivariable linear regression showed that IADLs (ß = 0.83, p < 0.001) and NPI subscores of apathy (ß = 3.83, p < 0.001)and irritability (ß = 4.25, p < 0.001) were positively associated with ZBI scores. The highest family monthly income (ß = - 10.92, p = 0.001) and caregiver age (ß = - 0.41, p = 0.001) were negatively correlated with ZBI scores. CONCLUSIONS: Older caregivers of older demented patients experience a higher care burden when patients had greater impaired functional autonomy and the presence of NPI symptoms of apathy and irritability. Our findings provide the direction to identify risky older caregivers, and we should pay more attention to and provide support for these exhausted caregivers.

Accountability and utilization of diabetes care from 2005 to 2014 in Taiwan.

BACKGROUND/PURPOSE: Diabetes mellitus (DM) prevalence has been rapidly increasing in Taiwan and globally. Team care for DM has been provided through diabetes shared-care networks in Taiwan more than 20 years. METHODS: The study analyzed the National Health Insurance (NHI) claims data from 2005 to 2014 to better understand diabetes care accountability and utilization in Taiwan. RESULTS: The completion rate of annual check-ups for various metabolic measurements increased significantly, which indicates improvement in diabetes management quality. The average annual visits and drug cost for each patient increased enormously from 2005 to 2014. The annual number of outpatient department/inpatient department (OPD/IPD) patients with diabetes undergoing dialysis increased. The number of OPD visits in patients with diabetes was 1.9 times higher than that in all patients in general. IPD cost appeared to increase, whereas both drug cost and the average length of hospitalization per patient decreased. Endocrine and metabolic diseases were still the leading cause of OPD expenses. The leading cause of IPD expenses was respiratory diseases. An increasing trend was noted in the medical cost for patients with microvascular instead of macrovascular complications. OPD care for patients with diabetes was rather evenly distributed since 2009. Regarding IPD care, medical centers and regional hospitals each hospitalized 37% of the diabetic outpatients in 2014. CONCLUSION: Accountability of diabetes care in Taiwan improved significantly till 2014. The ongoing fight against DM and tracing, examining and learning from the overall outcomes in future decades is still required.

Pay-for-performance for shared care of diabetes in Taiwan.

BACKGROUND/PURPOSE: Comprehensive and continuous care is crucial for patients with diabetes. The diabetes pay-for-performance (P4P) program launched by the National Health Insurance (NHI) administration in Taiwan provides a financial incentive to facilitate this goal. In this study, we explored the characteristics of patients in the P4P program between 2005 and 2014. METHODS: Data of patients with diabetes enrolled in the NHI program between 2005 and 2014 were extracted from the NHI research database. Patients were classed as having diabetes if they had three or more outpatient visits within 365 calendar days with an International Classification of Diseases, 9th Revision, Clinical Modification diagnostic code of 250 or hospitalization one or more times with such a diagnosis. The trends of participating in the P4P program were analyzed. RESULTS: Participation rate of the P4P program increased from 12.1% to 19% between 2005 and 2014. Participants were younger and more likely to be female than those not participating in the program. Lower risks of cancer-related mortality, annual mortality and heart failure were seen in patients participating in the P4P program than in those not participating. CONCLUSION: Older, male patients with a high disease severity may be less likely to enroll in the P4P program. Although participation rate is increasing, a broad enrollment is expected.

2019 Diabetes Atlas: Achievements and challenges in diabetes care in Taiwan.

The 2019 Diabetes Atlas delineated both accomplishments and challenges in diabetes care in Taiwan between 2005 and 2014. The series reported that Taiwan had significantly improved aspects of care quality for patients with diabetes. For example, the mortality rate decreased, the difference between the life expectancies of patients with diabetes and those of the general population decreased, and the rates of hospitalization because of heart diseases, cerebrovascular diseases, chronic kidney diseases, and unsatisfactory glycemic control decreased. However, despite these achievements, the 2019 Diabetes Atlas also reported some substantial challenges that have not been overcome. For example, the incidence of diabetes among women aged <19 years and 20-39 years increased by 27% and 33%, respectively. Furthermore, a high prevalence of macrovascular complications, a continuous increase in the dialysis prevalence rates among men with diabetes of all ages, and a low participation rate (<20%) of patients with diabetes in the pay-for-performance program were observed. The publication of the 2019 Diabetes Atlas is a milestone that demonstrates a strong will in medical societies to improve the quality of diabetes care. We expect this initiative can be reorganized every 5 years to report the results of continuous monitoring and surveillance and update the epidemiological features of diabetes in Taiwan.

Impact of a home health care program for disabled patients in Taiwan: A nationwide population-based cohort study.

The aim of this study was to evaluate the impact of home health care (HHC) for disabled patients.We conducted a nationwide population-based retrospective cohort study. A total of 5838 disabled patients with HHC were identified to match by propensity score with 15,829 disabled patients without HHC receiving tube or catheter care (tracheostomy tube, nasogastric tube, urinary catheter, cystostomy tube, nephrostomy tube) or stage 3 or 4 pressure sore care from the Taiwanese National Health Insurance Research Database between 2005 and 2009. After 1:1 matching, 2901 subjects in the HHC group and 2901 subjects in the non-HHC group were selected and analyzed. Generalized estimating equations (GEEs) were used to compare the risk of health outcomes (rate of hospitalization and emergency services use) and the healthcare expenditure between the 2 groups.Compared to those in the non-HHC group, the patients in the HHC group had significantly higher risk for hospitalization (odds ratio [OR] = 18.43, 95% confidence interval [CI]: 15.62-21.75, P < .001) and emergency services use (OR = 3.72, 95% CI: 3.32-4.17, P < .001) 1 year before the index date. However, 1 year after the index date, the risk for hospitalization (OR = 1.6, 95% CI: 1.41-1.83, P < .001) and emergency services use (OR = 1.16, 95% CI: 1.04-1.30, P < .05) attenuated significantly. Regarding the comparison of total healthcare expenditure 1 year before and after the index date, our study showed an insignificant decrease of US$1.5 per person per day and a significant increase of US$5.2 per person per day (P < .001) in the HHC and non-HHC groups, respectively.The HHC for disabled patients has a potential role to reduce hospitalization and emergency services use. Besides, the improvement of healthcare quality through HHC was not accompanied by increased healthcare expenditure. The clinical impact of HHC emphasizes the importance for public health officials to promote HHC model to meet the needs of disabled patients.

Association of Anemia and Iron Parameters With Mortality Among Patients Undergoing Prevalent Hemodialysis in Taiwan: The AIM - HD Study.

Background The Taiwan Health Insurance Bureau has conducted a bundled payment system for hemodialysis reimbursement since 1995. The maximum dose of erythropoiesis-stimulating agents allowed by insurance is capped at 20 000 U of epoetin or 100 µg of darbepoetin alfa per month. Nephrologists have avoided the use of high dosages of erythropoiesis-stimulating agents to achieve a hemoglobin level of 10 to 11 g/dL by iron supplementation. The clinical impact of these policies on patients' outcomes is unknown. The authors aimed to assess the AIM-HD (Association of Anemia, Iron parameters, and Mortality among the prevalent Hemodialysis patients) Study in Taiwan. Methods and Results The AIM-HD study was conducted based on the Taiwan Renal Registry Data System. From 2001 to 2008, the authors enrolled 42 230 patients undergoing hemodialysis who were older than 20 years and had received hemodialysis for more than 12 months. Patient follow-ups occurred until death or December 31, 2008. During a study period of 8 years, 12 653 (30.0%) patients died. After multivariate adjustment, the authors found that a hemoglobin level <10 g/dL was significantly associated with higher risk for all-cause and cardiovascular deaths. Moreover, a serum ferritin level between 300 and 800 ng/mL and transferrin saturation value between 30% and 50% were associated with the lowest all-cause mortality. Conclusions The authors recommend avoiding a low hemoglobin level and maintaining serum ferritin between 300 and 800 ng/mL and transferrin saturation between 30% and 50%, which were associated with lower risks of all-cause mortality among patients undergoing hemodialysis receiving the restricted erythropoiesis-stimulating agent doses but prompt intravenous iron supplementation in Taiwan.

Effect of national pre-ESRD care program on expenditures and mortality in incident dialysis patients: A population-based study.

Inadequate care of chronic kidney disease (CKD) is common and may be associated with adverse outcomes after dialysis. The nationwide pre-end-stage renal disease pay for performance program (P4P) has been implemented in Taiwan to improve quality of CKD care. However, the effectiveness of the P4P program in improving the outcomes of pre-dialysis care and dialysis is uncertain. We conducted a longitudinal cohort study. Patients who newly underwent long-term dialysis (≥3 mo) between 2007 and 2009 were identified from the Taiwan National Health Insurance Research Database. Based on the patient enrolment of the P4P program, they were categorized into P4P or non-P4P groups. We analysed pre-dialysis care, healthcare expenditures, and mortality between two groups. Among the 26 588 patients, 25.5% participated in the P4P program. The P4P group received significantly better quality of care, including a higher frequency of glomerular filtration rate measurement and CKD complications survey, a higher rate of vascular access preparation, and more frequent use of arteriovenous fistulas than the non-P4P group did. The P4P group had a 68.4% reduction of the 4-year total healthcare expenditure (excluding dialysis fee), which is equivalent to US$345.7 million, and a significant 22% reduction in three-year mortality after dialysis (hazard ratio 0.78, 95% confidence interval: 0.75-0.82, P < 0.001) compared with the non-P4P group. P4P program improves quality of pre-dialysis CKD care, and provide survival benefit and a long-term cost saving for dialysis patients.

Determinants of influenza vaccination in older adults: A nationwide community-based study in Taiwan.

AIMS: Influenza vaccination (InVa) is an effective measure for preventing influenza infection, which is a major cause of morbidity and mortality in older adults. However, the determinants of InVa remain unclear. METHODS: The present study included 4756 adults aged 55 years and older who completed the baseline examination of the Healthy Aging Longitudinal Study in Taiwan. During the examination, each participant received assessments of InVa status. Comprehensive assessments of sociodemographic (age, sex, education level, marital status, living alone and occupation) and health-related factors (chronic diseases, smoking status, alcohol intake, physical activities, cognitive status and physical performance) were also carried out. The InVa rate was defined as the number of participants who reported receiving free InVa divided by the total number of candidates for free InVa. Multinomial logistic regression analysis was applied to investigate the sociodemographic and health-related determinants of InVa status. RESULTS: The coverage rate of InVa was 44.8% (2130/4756). Older age (adjusted odds ratio [OR; >75 years vs <65 years] 7.72, 95% CI 6.26-9.52), multiple chronic diseases (OR [≥2 vs 0)] 1.31, 95% CI 1.10-1.65) and physical activity (OR [yes vs no] 1.43, 95% CI 1.23-1.64) were positively associated with receiving InVa. A current smoking status (OR 0.67, 95% CI 0.55-0.82) was negatively associated with receiving InVa. CONCLUSIONS: Older adults who received InVa differed from non-receivers in multiple sociodemographic and health-related characteristics. These findings support continual efforts to improve the InVa coverage rate in vulnerable populations. Geriatr Gerontol Int 2017; 17: 2396-2402.

Economic evaluation of a pre-ESRD pay-for-performance programme in advanced chronic kidney disease patients.

BACKGROUND: The National Health Insurance Administration in Taiwan initiated a nationwide pre-end-stage renal disease (ESRD) pay-for-performance (P4P) programme at the end of 2006 to improve quality of care for chronic kidney disease (CKD) patients. This study aimed to examine this programme's effect on patients' clinical outcomes and its cost-effectiveness among advanced CKD patients. METHODS: We conducted a longitudinal observational matched cohort study using two nationwide population-based datasets. The major outcomes of interests were incidence of dialysis, all-cause mortality, direct medical costs, life years (LYs) and incremental cost-effectiveness ratio comparing matched P4P and non-P4P advanced CKD patients. Competing-risk analysis, general linear regression and bootstrapping statistical methods were used for the analysis. RESULTS: Subdistribution hazard ratio (95% confidence intervals) for advanced CKD patients enrolled in the P4P programme, compared with those who did not enrol, were 0.845 (0.779-0.916) for incidence of dialysis and 0.792 (0.673-0.932) for all-cause mortality. LYs for P4P and non-P4P patients who initiated dialysis were 2.83 and 2.74, respectively. The adjusted incremental CKD-related costs and other-cause-related costs were NT$114 704 (US$3823) and NT$32 420 (US$1080) for P4P and non-P4P patients who initiated dialysis, respectively, and NT$-3434 (US$114) and NT$45 836 (US$1572) for P4P and non-P4P patients who did not initiate dialysis, respectively, during the 3-year follow-up period. CONCLUSIONS: P4P patients had lower risks of both incidence of dialysis initiation and death. In addition, our empirical findings suggest that the P4P pre-ESRD programme in Taiwan provided a long-term cost-effective use of resources and cost savings for advanced CKD patients.

Health policies on dialysis modality selection: a nationwide population cohort study.

OBJECTIVES: In Taiwan, peritoneal dialysis (PD) and haemodialysis are fully accessible to patients with end-stage renal disease. However, the usage of PD is considered low in Taiwan. Since 2005, 4 major policies have been implemented by Taiwan's Ministry of Health and Welfare, namely a multidisciplinary predialysis care programme and usage increasing the PD incidence as a key performance indicator (KPI) for hospital accreditation, both of which were implemented in 2006; reimbursement of the glucose-free dialysate, icodextrin that was implemented in 2007; and insurance reimbursement for renting automated PD machines that was implemented in 2008. The aim of this study was to analyse the associations between the PD promotional policies and the actual PD selection rates. SETTING: We analysed data within the Taiwan Renal Registry Data System from 2006 to 2013, focusing on the PD incidence in relation to the timings of the 4 PD promotional policies; then we stratified the results according to age, sex and the presence of diabetes mellitus. PARTICIPANTS: From 2006 to 2013, 115 565 patients were enrolled in this study. The mean (SD) age of patients on PD was 54.6 (15.7) years. RESULTS: During the time frame in which the 4 PD promotional policies were implemented, the PD incidence increased from 12.8% in 2006 to 15.1% in 2009. The PD incidence started to decline in 2010 (13.8%) when the hospital accreditation policy was repealed. The 3 remaining policies were weakly associated with the PD incidence. The observational analysis determined that the patients' ages, sexes and diabetes mellitus incidence rates were relatively stable from 2006 to 2013. CONCLUSIONS: Of the 4 health policies intended to promote PD usage, using increasing the PD incidence as a KPI for hospital accreditation had the strongest association with the PD incidence.
