Abstract
BACKGROUND Schizophrenia is one of the leading causes of disability. Paliperidone palmitate once-monthly injection (PP1M) was developed to provide consistent drug delivery and improve medication adherence for maintenance treatment. It is well known that patients with schizophrenia have higher cardiovascular risks, however little is known about the cardiovascular risks of patients with schizophrenia treated with PP1M in Asia. OBJECTIVE This study aimed to estimate the incidence of cardiovascular events after initiating PP1M treatment and evaluate the cardiovascular risk associations compared with oral second-generation antipsychotics (SGAs). METHODS Data from Taiwan's National Health Insurance Research Database were used to identify a cohort of adult patients with schizophrenia who received any SGAs from 1 March 2012 to 31 December 2018. Patients who initiated PP1M treatment were enrolled for descriptive analysis of incidence rates. PP1M patients were propensity matched 1:1 to patients initiating a new oral SGA, for comparative analysis based on demographics, clinical characteristics and treatment history at baseline, in three-step matching procedures, following the prevalent new-user design to enhance comparability. Follow-up ended at the end of the treatment episode of index drug, death, last record available, or end of the study (31 December 2019). Study endpoints included serious cardiovascular events (including severe ventricular arrhythmia and sudden death), expanded serious cardiovascular events (which further included acute myocardial infarction and ischemic stroke), and cardiovascular hospitalizations. Risks of study endpoints between matched cohorts were compared using Cox regression. RESULTS Overall, 11,023 patients initiating PP1M treatment were identified (49.5% were females; mean age of 43.2 [12.2] years). Overall incidences for serious cardiovascular events, expanded serious cardiovascular events, and cardiovascular hospitalizations were 3.92, 7.88 and 51.96 per 1000 person-years, respectively. In matched cohort analysis (N = 10,115), the hazard ratios (HRs) between initiating PP1M and a new oral SGA for serious cardiovascular events, expanded serious cardiovascular events, and cardiovascular hospitalizations were 0.86 (95% confidence interval [CI] 0.55-1.36), 0.88 (95% CI 0.63-1.21), and 0.78 (95% CI 0.69-0.89), respectively. CONCLUSION This study reported the population-based incidence of cardiovascular events in schizophrenic patients initiating PP1M treatment. PP1M was not associated with increased risks of serious cardiovascular events but was potentially associated with lower risks of cardiovascular hospitalizations compared with oral SGAs.

Abstract
BACKGROUND Connections between long-term use of topical corticosteroids (TCSs) of varying potency and osteoporosis and major osteoporotic fracture (MOF) are unclear. Susceptibility to adverse bone effects of TCSs in different sex, age and ethnic groups is unknown too. OBJECTIVES To demonstrate the association between cumulative dose of TCSs of varying potency and osteoporosis and MOF in Taiwanese population, with stratified analysis of sex and age. METHODS We conducted a nationwide case-control study and obtained data from Taiwan National Health Insurance Research Database. Cumulative TCS doses in different exposure periods were calculated, and the potency of TCSs was converted to prednisolone equivalent. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for osteoporosis and MOF associated with TCS use. RESULTS From 2017 to 2020, 129,682 osteoporosis cases and 34,999 MOF cases were selected and randomly matched with 518,728 and 139,996 controls by sex and age. We found clear dose-response relationships between long-term TCS exposure and osteoporosis and MOF. For example, compared to no TCS use, adjusted ORs of osteoporosis were 1.216 (95% CI 1.189-1.243), 1.260 (95% CI, 1.241-1.280) and 1.341 (95% CI, 1.314-1.369) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Adjusted ORs of MOF were 1.118 (95% CI 1.069-1.170), 1.191 (95% CI, 1.156-1.227) and 1.288 (95% CI, 1.238-1.340) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Stratified analysis showed women had higher ORs of osteoporosis and MOF compared to men. Younger people (<50 years) had highest OR of osteoporosis compared to other age groups. CONCLUSIONS Higher cumulative TCS dose was associated with increased risk of osteoporosis and MOF. Long-term use of TCSs should be cautious, especially in susceptible populations such as women and young people.

Abstract
Posterior chamber phakic intraocular lens (pIOL) implantation has been widely adopted for the correction of refractive errors. Among pIOLs, the Implantable Collamer Lens is the most common choice. The selection of the appropriate pIOL size and achieving the desired postoperative vault to minimize complications has consistently been a focal point in academic research. With the advancement of ophthalmic biometric measurement technology and the application of artificial intelligence in the field of medicine, numerous new technologies and methods for pIOL size selection and vault prediction have emerged in recent years. This paper provides a comprehensive review on the topic of how to choose the pIOL size and predict the vault.

Abstract
Bullous pemphigoid has a high incidence among dialysis patients. However, whether or not chronic dialysis is an independent risk factor of bullous pemphigoid remains unclear. We aimed to investigate the effect of chronic dialysis on the development of bullous pemphigoid and pemphigus. We performed a retrospective cohort study using records from Taiwan's National Health Insurance Research Database between 2008 and 2019. We identified a dialysis cohort that included patients on chronic hemodialysis and peritoneal dialysis, and the hazard ratios (HRs) for bullous pemphigoid and pemphigus were compared with those of a sex-, age-, and index-matched cohort, then the results were adjusted for various confounding factors. Among 93 538 patients on chronic dialysis and 93 538 patients in the control group, 287 and 139 developed incident bullous pemphigoid, and 45 and 35 developed incident pemphigus after a median follow-up of 3.7 and 5.6 years, respectively. The incidence rates of bullous pemphigoid in the dialysis patients and the control group were 74.2 and 25.2 per 100 000 person-years, respectively (difference between groups, P < 0.0001). The incidence rates of pemphigus in the dialysis patients and the control group were 11.6 and 6.3 per 100 000 person-years, respectively (difference between groups, P < 0.01). Cox proportional hazard adjustment showed the HR for bullous pemphigoid in dialysis patients was 2.12 (95% confidence interval [CI] 1.64-2.74, P < 0.0001) compared with the control group. Dialysis patients aged <75 years had an even higher risk of bullous pemphigoid development (5- to 8-fold) than the control group. The adjusted HR for pemphigus was not elevated in dialysis patients (adjusted HR 1.52, 95% CI 0.87-2.67, P = 0.14). Chronic dialysis is an independent risk factor for developing bullous pemphigoid, but not a risk factor for pemphigus. Physicians should be aware of the predisposition of chronic dialysis patients to bullous pemphigoid.

Abstract
Objective: To investigate the clinical characteristics of hospitalized children infected with the Omicron variant in Kunming after the withdrawal of non-pharmaceutical interventions (NPI) and analyze the risk factors of severe cases. Methods: Clinical data was retrospectively collected from 1 145 children with SARS-CoV-2 Omicron infection who were hospitalized in six tertiary grade A hospitals in Kunming from December 10th, 2022 to January 9th, 2023. According to clinical severity, these patients were divided into the general and severe SARS-CoV-2 groups, and their clinical and laboratory data were compared. Between-group comparison was performed using t-test, chi-square test and Mann-Whitney U test. Spearman correlation test and multivariate Logistic regression analysis were used to determine the risk factors of severe illness. Results: A total of 1 145 hospitalized patients were included, of whom 677 were male and 468 female. The age of these patients at visit was 1.7 (0.5, 4.1) years. Specifically, there were 758 patients (66.2%) aged ≤3 years at visit and 387 patients (33.8%) aged >3 years. Of these children, 89 cases (7.8%) had underline diseases and the remaining 1 056 cases (92.2%) had no combined diseases. Additionally, of all the patients, 319 cases (27.9%) were vaccinated with one or two doses of SARS-CoV-2 vaccine, 748 cases (65.3%) had acute upper respiratory tract infection (AURTI), and six cases died (0.5%). A total of 1 051 cases (91.8%) were grouped into general SARS-CoV-2 group and 94 cases (8.2%) were grouped into severe SARS-CoV-2 group. Compared with the general cases, the severe cases showed a lower rate of SARS-CoV-2 vaccination and younger median age, lower lymphocyte count, as well as proportions of CD8+T lymphocyte (36 cases (38.3%) vs. 283 cases (26.9%), 0.5 (2.6, 8.0) vs. 1.6 (0.5, 3.9) years, 1.3 (1.0, 2.7) ×109 vs. 2.7 (1.3,4.4)×109/L, 0.17 (0.12, 0.24) vs. 0.21 (0.15, 0.16), respectively, χ2=4.88, Z=-2.21,-5.03,-2.53, all P<0.05). On the other hand, the length of hospital stay, proportion of underline diseases, ALT, AST, creatine kinase isoenzyme, and troponin T were higher in the severe group compared to those in the general group ((11.6±5.9) vs. (5.3±1.8) d, 41 cases (43.6%) vs. 48 cases (4.6%), 67 (26,120) vs. 20 (15, 32) U/L, 51 (33, 123) vs. 44 (34, 58) U/L、56.9 (23.0, 219.3) vs. 3.6 (1.9, 17.9) U/L, 12.0 (4.9, 56.5) vs. 3.0 (3.0, 7.0) ×10-3 pg/L,respectively, t=-20.43, χ2=183.52, Z=-9.14,-3.12,-6.38,-3.81, all P<0.05). Multivariate regression analysis indicated that increased leukocyte count (OR=1.88, 95%CI 1.18-2.97, P<0.01), CRP (OR=1.18, 95%CI 1.06-1.31, P<0.01), ferritin (OR=1.01, 95%CI 1.00-1.00, P<0.01), interleukin (IL)-6 (OR=1.05, 95%CI 1.01-1.08, P=0.012), D-dimer (OR=2.56, 95%CI 1.44-4.56, P<0.01) and decreased CD4+T lymphocyte (OR=0.84, 95%CI 0.73-0.98, P=0.030) were independently associated with the risk of severe SARS-CoV-2 in hospitalized children with Omicron infection. Conclusions: After the withdrawal of NPI, the pediatric inpatients with Omicron infection in Kunming were predominantly children younger than 3 years of age, and mainly manifested as AURTI with relatively low rate of severe SARS-CoV-2 infection and mortality. Elevated leukocyte counts, CRP, ferritin, IL-6, D-dimer, and decreased CD4+T lymphocytes are significant risk factors for developing severe SARS-CoV-2 infection.

Abstract
IMPORTANCE The cancer risks associated with treatment with topical calcineurin inhibitors (TCIs) in patients with atopic dermatitis (AD) remain controversial, and limited evidence exists regarding the cancer risks among patients with AD treated with TCIs in Asian populations. OBJECTIVES This study identified the association between TCI use and the risks of developing all cancers, lymphoma, skin cancers, and other cancers. DESIGN This study was a nationwide, population-based, retrospective cohort study. SETTING Taiwan's National Health Insurance Research Database. PARTICIPANTS Patients diagnosed at least twice with ICD-9 code 691 or at least one time with ICD-9 codes 691 or 692.9 within 1 year between 1 January 2003 and 31 December 2010 were included and followed until 31 December 2018. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using the Cox proportional hazard ratio model. EXPOSURES Patients using tacrolimus or pimecrolimus were identified in the National Health Insurance Research Database and compared with patients using topical corticosteroids (TCSs). MAIN OUTCOMES AND MEASURES The main outcomes were hazard ratios (HRs) of cancer diagnoses and associated outcomes obtained from the Taiwan Cancer Registry database. RESULTS After propensity score (PS) matching, the final cohort included 195,925 patients with AD, including 39,185 who were initial TCI users and 156,740 who were TCS users. Propensity score matching was performed according to age, sex, index year, and Charlson Comorbidity Index using a ratio of 1:4. Except for leukemia, HR and 95% CI showed no significant associations between TCI use and the risk of developing all cancer, lymphoma, skin cancers, and other cancers. Sensitivity analysis showed that the lag time HRs for every cancer subtype continued to show no significant association between TCI use and cancer risk, except for leukemia. CONCLUSIONS AND RELEVANCE Our study found no evidence to support an association between TCI use and the risks of almost all cancers compared with TCS use in patients with AD, but physicians should be aware of potentially higher risks of leukemia with TCI use. This study represents the first population-based study focused on the cancer risk of TCI use among patients with AD in an Asian population.

Abstract
Objective Limited evidence exists regarding real-world 3-monthly paliperidone palmitate (PP3M) treatment retention and associated factors. Methods We conducted a retrospective, nationwide cohort study using the Taiwan National Health Insurance Research Database between October 2017 and December 2019. Adult patients with schizophrenia initiated on PP3M were enrolled. The primary outcomes were time to PP3M discontinuation, time to psychiatric hospitalization, and the proportions of patients receiving the next PP3M dose within 120 days among first-, second-, and third-dose completers. Key covariates included prior PP1M duration and adequate PP3M initiation. Results The PP3M treatment retention rates were 79.7%, 66.3%, and 52.5% after 6, 12, and 24 months, respectively, with 86.4%, 90.6%, and 90.0% of respective first-, second-, and third-dose completers receiving the next PP3M dose. Adequate PP3M initiation and prior PP1M treatment duration > 180 days were associated with favorable PP3M treatment retention. In multivariate analyses, PP1M durations of 180-360 days (adjusted relative risk [aRR], 1.76) or < 180 days (aRR, 2.79) were associated with PP3M discontinuation at the second dose. Inadequate PP3M initiation was associated with discontinuation at the third dose (aRR, 2.18). Patients fully adherent to PP3M treatment in the first year had a higher probability of being free from psychiatric hospitalization (86.7% at 2 years), compared with those partially adherent or non-adherent to PP3M in the first year. Conclusion Prior PP1M duration and adequate PP3M initiation are major factors affecting PP3M treatment retention. Higher PP3M treatment retention is associated with a lower risk of psychiatric hospitalization.

Abstract
Background We estimated healthcare resource utilization (HRU) and costs in patients with generalized myasthenia gravis (gMG) in Taiwan. Methods This retrospective population-based, matched cohort study used the National Health Insurance Research Database to identify prevalent patients with gMG (cases) in 2019. In total, 2537 cases were matched (1:4) by age, sex, and urbanization level to 10148 randomly selected patients without gMG (comparators). A generalized linear regression model predicted the frequency of HRU and costs among service users. Costs attributable to gMG were obtained by subtracting all-cause HRU costs incurred by comparators from cases. Results The mean age of all patients was 54.99 years and 55.97% were female. Compared with comparators, cases had significantly higher rates of hypertension (33.03%/24.26%), diabetes mellitus (18.92%/11.37%), malignancies (16.00%/4.08%), cardiovascular disease (11.35%/8.12%), thyroid-related conditions (5.99%/1.16%), respiratory illness/disorders (4.38%/1.22%), and neurotic disorders (4.65%/2.6%). Amongst users of healthcare resources, cases had a mean 10 additional outpatient visits, 0.62 inpatient stays, and 0.49 emergency room visits in 2019 compared with comparators (p < 0.0001 for all). The mean (standard deviation) difference in all-cause healthcare costs between cases and comparators was NT$ 94997 (76431) [US$ 3133 (2521)], and was significantly higher for all categories (outpatient, inpatient, emergency room, drugs; p < 0.0001 for all). Among employed persons, 13.18%/7.59% of cases/comparators changed employment status during the study (p < 0.0001). Conclusion gMG presents a substantial burden on HRU and healthcare costs in Taiwan. A high attrition rate from full-time employment suggests additional societal costs. Improved treatments are needed to alleviate the burden of disease on individuals, healthcare systems, and economies.

Abstract
Background The prevalence of myasthenia gravis is increasing in many countries, including Asia. As treatment options expand, population-based information about the disease burden can inform health technology assessments. Methods We conducted a population-based retrospective cohort study using the Taiwan National Healthcare Insurance Research database and Death Registry to describe the epidemiology, disease burden and treatment patterns of generalized myasthenia gravis (gMG) from 2009 to 2019. Episodes of hepatitis B virus (HBV) infection or reactivation were explored. Results The number of patients with gMG increased from 1,576 in 2009 to 2,638 in 2019 and the mean (standard deviation) age from 51.63 (17.32) to 55.38 (16.29) years. The female:male ratio was 1.3:1. Frequently reported co-morbidities were hypertension (32-34% of patients), diabetes mellitus (16-21%) and malignancies (12-17%). The prevalence of patients with gMG increased annually from 6.83/100,000 population in 2009 to 11.18/100,000 population in 2019 (p < 0.0001). There was no temporal trend in all-cause fatality rates (range 2.76-3.79/100 patients annually) or gMG incidence rates (2.4-3.17/100,000 population annually). First-line treatment was with pyridostigmine (82%), steroids (58%), and azathioprine (11%). There was minimal change in treatment patterns over time. Among 147 new HBV infections, 32 (22%) received ≥4 weeks of antiviral therapy suggesting chronic infection. The HBV reactivation rate was 7.2%. Conclusion The epidemiology of gMG in Taiwan is evolving rapidly, with higher prevalence rates and increasing involvement of older age-groups suggesting a growing burden of disease and associated healthcare costs. HBV infection or reactivation may pose a previously unrecognized recognized risk for patients with gMG receiving immunosuppressants.

Abstract
Depression increases an individual's risk of work disability, sick leave, unemployment, and early retirement. This population-based study identified 3673 depressive patients utilizing national claim data from Taiwan and aimed to investigate changes in employment status among depressive patients, compared to matched controls, with the longest observation of up to 12 years. This study found depressive patients had an adjusted hazard ratio of 1.24 for changing to non-income earners compared to controls. Moreover, younger age, lower payroll bracket, urbanity, and geographical area were associated with increased risk among patients with depression. Despite these increased risks, most depressive patients remained employed.

Abstract
BACKGROUND Determining the proportion of patients with treatment-resistant depression (TRD) among patients with unipolar depression receiving adequate pharmacological treatment (pharmaceutically treated depression [PTD]) is clinically important and may affect health care utilization. In Taiwan, these issues can be assessed by analyzing population-based data. METHODS The present study included data from the Taiwan National Health Insurance Research Database from 2010 to 2017. Among patients with depression, PTD was defined by the receipt of at least one adequate antidepressant treatment, and TRD was defined as receiving a third adequate antidepressant treatment after failure to respond to two prior treatments. Time of progression from PTD to TRD was estimated via the Kaplan-Meier function. A propensity-matched case-comparison cohort approach was used to compare resource utilization between patients with non-TRD PTD and TRD. RESULTS TRD was defined in 11.2 % of patients with unipolar depression and 37.1 % of PTD patients. The time of progression from PTD to TRD was approximately 1 year. Most TRD patients were women, middle-aged, and treated in general practice clinics. Antidepressant monotherapy, followed by antidepressant with augmentation, was the most common treatment strategy applied to TRD patients. Medical utilization was significantly higher in patients with TRD than those with non-TRD PTD across most aspects. LIMITATIONS TRD was defined based on pharmacological treatment patterns, as the reasons for changes in antidepressant regimens were not available. CONCLUSION Approximately one-third of patients with PTD developed TRD, often soon after receiving adequate pharmacological treatment. Patients with TRD used more medical resources than patients with non-TRD PTD.

Abstract
Objectives
This study assessed risk adjustment performance of six comorbidity indices in two categories of comorbidity measures: diagnosis-based comorbidity indices and medication-based ones in patients with chronic obstructive pulmonary disease (COPD).
Methods
This was a population–based retrospective cohort study. Data used in this study were sourced from the Taiwan National Health Insurance Research Database. The study population comprised all patients who were hospitalized due to COPD for the first time in the target year of 2012. Each qualified patient was individually followed for one year starting from the index date to assess two outcomes of interest, medical expenditures within one year after discharge and in-hospital mortality of patients. To assess how well the added comorbidity measures would improve the fitted model, we calculated the log-likelihood ratio statistic G2. Subsequently, we compared risk adjustment performance of the comorbidity indices by using the Harrell c-statistic measure derived from multiple logistic regression models.
Results
Analytical results demonstrated that that comorbidity measures were significant predictors of medical expenditures and mortality of COPD patients. Specifically, in the category of diagnosis-based comorbidity indices the Elixhauser index was superior to other indices, while the RxRisk-V index was a stronger predictor in the framework of medication-based codes, for gauging both medical expenditures and in-hospital mortality by utilizing information from the index hospitalization only as well as the index and prior hospitalizations.
Conclusions
In conclusion, this work has ascertained that comorbidity indices are significant predictors of medical expenditures and mortality of COPD patients. Based on the study findings, we propose that when designing the payment schemes for patients with chronic diseases, the health authority should make adjustments in accordance with the burden of health care caused by comorbid conditions.

Abstract
Background: Biologics are used to treat moderate-to-severe psoriasis, and persistence to biologics may reflect clinical effectiveness. Limited information describing how biologics are used in patients with moderate-to-severe psoriasis in Asian countries is available. We conducted a population-based, retrospective, new user cohort study using the National Health Insurance Research Database (NHIRD) in Taiwan to assess treatment persistence and adherence to biologics. Methods: Adults with a diagnosis of psoriasis between 01 January 2015 and 31 December 2017 were identified in the NHIRD (ICD-9-CM 696.1; ICD-10 L40.0). New users were patients who initiated treatment with etanercept, adalimumab, ustekinumab or secukinumab between 01 January 2015 and 31 December 2017. All eligible patients were followed until 31 December 2018, death or disenrollment. Kaplan-Meier analysis was conducted to estimate persistence of treatment for index biologics. A Cox-proportional hazard regression model was used to compare risks of biologic discontinuation between biologic groups. Adjustments for potential confounding factors (age, gender and Charlson comorbidity index score) were made in the Cox model. Results: There were 1,397 new biologic users with psoriasis during the study period. The ratio men:women was approximately 4:1. Mean age of patients ranged from 44.6 to 47.7 years across exposure groups. The 1-year/2-years persistence rates were 94.2%/84.9% for ustekinumab, 96.2%/not calculated (due to too few patients at year 2) for secukinumab, 66.0%/29.9% for etanercept, and 59.8%/40.3% for adalimumab. The risk of discontinuation was significantly lower in patients initiating ustekinumab compared with adalimumab (hazard ratio adjusted for age, sex and co-morbidities 0.289, 95%CI 0.247-0.339, p < 0.0001). Drug survival was significantly higher for ustekinumab compared with adalimumab and etanercept (log-rank test p < 0.0001). The proportions of patients with 1-year/2-years medication possession ratios of ≥80% were 95.3%/92.0% for ustekinumab, 98.1%/not calculated for secukinumab, 89.4%/83.1% for etanercept, and 70.8%/59.4% for adalimumab. Limitations: Clinical improvement and response to treatment data were not available. Conclusion: There was relatively high persistence amongst biologic users with psoriasis in Taiwan. There is a trend towards greater persistence of ustekinumab compared to other biologics, the magnitude of which depends on the treatment gap used for its calculation. This study provides real-world evidence that may facilitate optimal treatment choice.

Abstract
Background Limited studies on atopic dermatitis (AD) have investigated the possible covariance of sociodemographic factors with the Hospital Anxiety and Depression Scale (HADS). Objective This study aimed to examine the possible covariance between AD severity and HADS scores of patients in Taiwan. Methods Patients with AD from a medical center and 2 regional hospitals in Taiwan were enrolled in this cross-sectional study from April 2018 to April 2019. AD severity was measured using the “scoring atopic dermatitis” index, and anxiety and depression were screened based on HADS. Results A total of 200 patients were included. After correcting for sociodemographic variables, significantly more borderline (≥8) and abnormal (≥11) cases of anxiety/depression (P < .05) were noted in patients with moderate-to-severe AD. Limitations First, the cross-sectional study design cannot show causality. Second, baseline data, including a history of underlying cancer or previous psychiatric disorder, were not obtained in the questionnaire and may confound the HADS scores. Finally, a standardized psychiatric clinical interviews study design should be used for higher accuracy in the assessment of psycho-comorbidities. Conclusion Higher anxiety and depression risks were noted in patients with moderate-to-severe AD. Except for psychosomatic symptoms, all kinds of anxiety and depression symptoms occurred more frequently in patients with moderate-to-severe AD.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common chronic skin disease. Only relatively scant studies from Asian countries have attempted to quantify AD-associated healthcare utilization and costs by using population-based databases. This study aims to evaluate the AD-associated annual healthcare utilization and costs in Taiwan. METHODS A retrospective matched-cohort study was conducted by matching the AD cases with controls at a 1:4 (cases:controls) ratio, with the data for both the cases and controls being sourced from the 2017 National Health Insurance Research Database (NHIRD). The AD patients were stratified by disease severity based on their treatments. Differences in the regression-adjusted frequency of care and costs between the cases and controls were compared using t-tests by the severity level of AD. RESULTS The incremental frequency of outpatient visits per year increased with AD severity (9.60, 11.28, and 16.23 for mild, moderate, and severe cases, respectively). However, the frequency of inpatient care and emergency room visits per year showed no consistent pattern associated with disease severity. The incremental total costs per year were NT$9,511.64, NT$9,705.20, and NT$15,762.09 for mild, moderate, and severe cases, respectively, and the outpatient and drug costs accounted for 46.65%-54.82% and 17.01%-31.20% of the total costs, respectively. CONCLUSION AD was found to impose significant healthcare costs, with estimated total cost burdens of NT$3.61 billion in 2017, which is 0.314% of Taiwan's national health expenditure and 0.020% of Taiwan's gross domestic product.

Abstract
BACKGROUND To ascertain the efficacy, safety, and immunogenicity from existing evidence via conducting a meta-analysis of randomized controlled trials between biosimilar and originator insulins. METHODS The PubMed, Cochrane Library, EMBASE, and ClinicalTrails.gov were searched to identify head-to-head randomized controlled trials (RCTs) that directly compare the efficacy and safety of biosimilar insulin and its originator. Efficacy was assessed by change of HbA1C, fasting plasma glucose (laboratory or self-monitoring of blood glucose (SMBG)), and change all mean of 7 points- or 8 points- SMBG. Safety was assessed by change in proportion hypoglycemia and serious hypoglycemia. The occurrence of anti-insulin antibodies (AIAs) was also evaluated. RESULTS Fourteen RCTs with 6188 patients from different countries were included. Data were pooled using a random-effects model and were expressed as the mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). In efficacy, Insulin biosimilar products showed similar in change of HbA1C at weeks 26 and 52, the MD were 0.03 (95% CI - 0.02 to 0.07, p = 0.28), and 0.05 (95% CI - 0.05 to 0.15, p = 0.36), respectively. The proportion of HbA1C less than 7% at endpoint, the OR were 1.04 (95% CI 0.89 to 1.20, p = 0.64). The change of fasting plasma glucose (laboratory or SMBG) mmol/L in 24-52 weeks and change all mean of 7 points-/8 points- SMBG mmol/L in 24-52 weeks, the MD were 0.02 (95% CI - 0.20 to 0.24, p = 0.87) and - 0.34 (95% CI - 1.35 to 0.67, p = 0.51), respectively. In occurrence of hypoglycemia (≥ 1 events) and severe hypoglycemia, the OR were 0.96 (95% CI 0.85 to 1.09, p = 0.52) and 1.06 (95% CI 0.85 to 1.31, p = 0.62). The AIA was 1.02 (95% CI 0.90 to 1.16, p = 0.76). Analysis stratified by type of diabetes and duration of insulin. There was no significant difference between the biosimilar and their reference group in a different type of diabetes and different duration of insulin. CONCLUSIONS Insulin biosimilar showed comparable characteristics with the reference drug in terms of efficacy, safety, immunogenicity, through comprehensive and specific conventional meta-analysis.

Abstract
Background To date, there has been no large-scale, real-world study of the health-related quality of life outcomes for patients using tumor treating fields (TTFields) therapy for glioblastoma (GBM) treatment. Methods A survey was mailed to 2,815 patients actively using TTFields for treatment of GBM in the USA (n = 2,182) and Europe (n = 633). The survey included patient-reported demographic and clinical information, as well as EuroQol’s EQ-5D-5L and visual analogue scale (EQ-VAS) overall health score. Results A total of 1,106 applicable patients responded to the survey (USA = 782 and Europe = 324), with a mean age of 58.6 years (SD = 12.3). The average time since diagnosis and time using TTFields were 21.5 months (SD = 25.1) and 13.5 months (SD = 13.2), respectively. Over 61% of patients had been diagnosed at least 1 year prior and 28.4% at least 2 years prior; 45 patients (4.2%) had been diagnosed at least 5 years prior. Progressed disease was reported in 307 patients, while 690 reported non-progressed disease. Regression analyses showed that GBM disease progression and older age had predictable negative associations (p < 0.001) with most EQ-5D-5L dimensions and the EQ-VAS. However, longer time since diagnosis was associated with improved self-care (p < 0.05), usual activities (p < 0.01), and EQ-VAS (p < 0.05) overall and in patients with progressed disease (p < 0.01, p < 0.05, and p < 0.01, respectively). Additionally, longer time using TTFields was associated with improved mobility (p < 0.05), self-care (p < 0.001), usual activities (p < 0.01), and EQ-VAS (p < 0.01) overall; with improved EQ-VAS in progression-free patients (p < 0.05); and with improved mobility (p < 0.05), self-care (p < 0.01), usual activities (p < 0.05), and EQ-VAS (p < 0.05) in patients with progressed disease. Conclusion This is the largest real-world study of patient-reported quality of life in GBM and TTFields treatment to date. It shows unsurprising negative associations between quality of life and disease progression and older age, as well as more novel, positive associations between quality of life and longer time since diagnosis and time using TTFields therapy.

Abstract
BACKGROUND To investigate the age and gender differences among chronic dialysis patients who developed genitourinary cancers in Taiwan. PATIENTS AND METHODS Incident hemodialysis patients aged 20 years or older were selected for retrospective cohort study from the National Health Insurance Research Database between 2002 and 2015, and the Taiwan Cancer Registry Database between 2007 and 2015. A two-step approach was employed to find the respective matched controls of non-dialysis patients. Finally, 65,450 dialysis patients and 261,800 non-dialysis patients were matched for further analysis. New diagnosis of genitourinary cancers during follow-up was the primary outcome of interest. RESULTS Dialysis was significantly associated with increased risk of all types of genitourinary cancers (P < .001), substantially within the first two years after dialysis initiation. Cox proportional hazard analysis showed a significantly increased hazard ratio (HR 6.58, 95% CI 6.05-7.16) among dialysis patients after multivariate adjustment, and the highest risk was bladder cancer (HR 7.85, 95% CI 6.97-8.84). Subgroup analysis showed younger dialysis patients (20-49 years old) had the highest risk of genitourinary cancer, especially females, in this subgroup with the highest risk of bladder cancer (HR 58.08, 95% CI 13.88-243.06). CONCLUSION The risks of all site-specific genitourinary cancers were increased in chronic dialysis patients, especially in younger females. Developing different screening strategies for these high-risk patients is necessary. MICRO ABSTRACT This study compared the effect of sex, age and dialysis duration on the susceptibility to develop genitourinary cancers in dialysis patients through the national health database linkage in Taiwan. We matched 65,450 dialysis patients and 261,800 non-dialysis patients for further analysis. Younger and female dialysis patients were at higher risk of kidney and bladder cancers.

Abstract
INTRODUCTION Studies have reported higher risks of mortality for patients with schizophrenia, compared to the general population. This study aimed to evaluate the risk of all-cause, sudden death, and cardiovascular mortality among patients with schizophrenia in terms of types of antipsychotics. METHODS A retrospective cohort study assessed the risk of mortality among antipsychotic-treated patients with schizophrenia. The study linked the Taiwan National Health Insurance (NHI) claims and National Register of Death databases from 2001 to 2015. Patients were hierarchically assigned to the following index antipsychotic treatment groups: atypical long acting injection (LAI), typical LAI, atypical oral, and typical oral. RESULTS A total of 68,159 antipsychotic-treated patients with schizophrenia were analyzed. Under the hierarchical grouping, the largest percentages of patients were on atypical oral antipsychotic regimens (65.51%), followed by typical oral (14.00%), typical LAI (12.84%), and atypical LAI (7.65%). Typical oral patients had the highest incidence of all-cause mortality of 27.48 per 1000 patient-years and the atypical LAI group had the lowest incidence (13.95 per 1000 patient-years). Compared to typical oral users, there were lower risks of all-cause mortality for users of atypical LAI (aHR = 0.62, 95% CI: 0.47-0.81), typical LAI (aHR = 0.65, 95% CI: 0.55-0.78), and atypical orals (aHR = 0.55, 95% CI: 0.49-0.62). CONCLUSION Compared to typical oral users, we found a lower risk of all-cause mortality, sudden death, and cardiovascular mortality among schizophrenia users of LAIs and oral atypicals. Further research is warranted to characterize the risk of mortality among users of more recently available LAIs in the Asia Pacific region and elsewhere.

Abstract
Hip fracture is a significant health problem and is associated with increased mortality. Patients with chronic kidney disease (CKD) are more at risk of hip fracture than the general population, but the hip fracture risk is not evident among non-dialysis CKD stage 5 patients. This study aims to assess the risk of hip fracture in patients with non-dialysis CKD stage 5 comparing to those with CKD stages 1–4. Patients with non-dialysis CKD stage 5 and CKD stages 1–4 were retrieved from Taiwan longitudinal health insurance database 2011–2014. All patients were followed to the end of 2018 for the development of hip fractures. We analyze the risk of hip fracture of propensity score-matched patients with CKD stage 5 compared to patients with CKD stages 1–4 using stepwise Cox regression and competing risks regression. We analyzed 5649 propensity score-matched non-dialysis CKD 1–4 patients and non-dialysis CKD 5 patients between 2011 and 2014. All patients were followed to the end of 2018, 229 (4.1%) of CKD 1–4 patients in 21,899 patient-year, and 290 (5.1%) of CKD 5 patients had hip fractures in 18,137 patient-year. CKD 5 patients had a higher risk of hip fracture than patients with CKD stages 1–4. The adjusted HR was 1.53 (95% CI 1.08–1.54) in the Cox regression with adjustments for age, gender, comorbidity, and history of fracture. In the competing risks regression, the subdistribution hazard ratio was 1.29 (95% CI 1.08–1.54). Female gender, age, history of fractures, and Charlson–Deyo comorbidity index were independently associated with increased hip fracture risks. Non-dialysis CKD 5 patients had a higher risk of hip fracture than patients with CKD stages 1–4. This association is independent of patients’ age, female gender, history of fractures, and comorbidities.

Abstract
Atopic dermatitis has a substantial impact on work and activity impairment according to studies from Western communities. Prospective studies of work productivity and activity impairment in Asian patients with atopic dermatitis are lacking. The aims of this study were to investigate the impacts of atopic dermatitis on work productivity and activity impairment among Taiwanese patients, and to stratify the analyses by disease severity. One-third of employed participants reported missing work (absenteeism) in the preceding week due to atopic dermatitis, while 88.5% of the remaining two-thirds reported impaired work effectiveness (presenteeism). In addition, 92.5% of all participants reported impaired daily activities. Overall work impairment (aggregate productivity loss from absenteeism and presenteeism) was 1.8- and 2.6-fold greater in subjects with moderate and severe atopic dermatitis, respectively, compared with those with mild atopic dermatitis. Presenteeism, but not absenteeism, contributes to the majority of total work impairment in this cohort. Daily activity impairment was 1.5-fold greater in moderate atopic dermatitis, and 2.0-fold greater in severe atopic dermatitis, compared with mild atopic dermatitis. Both work and activity impairment showed significant positive correlations with atopic dermatitis severity scores (SCORing Atopic Dermatitis; SCORAD). In conclusion, work productivity and activity impairment is significantly correlated with disease severity in this Taiwanese atopic dermatitis cohort. In order to obtain a full picture of disease burden to patients and caregivers, patients with atopic dermatitis should be monitored for disease activity as well as corresponding impacts on quality of life.

Abstract
Background This study utilized a population‐based claims database to identify patients with beta‐thalassemia and evaluate associations between transfusion burden, healthcare resource utilization (HCRU), and complications. Study design and methods Taiwan's National Health Insurance Research Database was used to identify patients with beta‐thalassemia (ICD‐10 D56.1) in 2016. Patients with a beta‐thalassemia claim in 2016 were indexed into the study at their first claim on or after January 1, 2001 in the dataset through to December 31, 2016 and followed until the end of study. During the follow‐up period, red blood cell transfusion (RBCT) units, HCRU, iron chelation therapy use, and beta‐thalassemia‐related complications incidence were recorded. Patients were grouped into transfusion burden severity cohorts based on average number of RBCT units per 12 weeks during follow‐up: 0 RBCT units, >0 to <6 RBCT units (mild), ≥6 to <12 RBCT units (moderate), and ≥12 RBCT units (severe). Results A total of 2984 patients were included with mean follow‐up of 6.95 years. Of these, 1616 (54.2%) patients had no claims for RBCT units, 1112 (37.3%) had claims for >0 to <6 RBCT units, 112 (3.8%) for ≥6 to <12 RBCT units, and 144 (4.8%) for ≥12 RBCT units per 12 weeks. Transfused patients had significantly more all‐cause HCRU and iron chelation therapy compared with non‐transfused patients during follow‐up. Thalassemia‐related HCRU and risk of liver, endocrine, cardiac, and renal complications were significantly and positively correlated with increases of RBCT units. Discussion Clinical and healthcare resource burden of patients with beta‐thalassemia is closely related to transfusion burden.

Abstract
Objective: To investigate the epidemiology and clinical characteristics of adenovirus (ADV)-caused acute respiratory tract infection among hospitalized children in Kunming, China. Methods: Clinical and laboratory data were collected from 467 children with adenovirus infection who were hospitalized from January 1, 2019 to December 31, 2019 in 6 grade A class Ⅲ hospitals in Kunming area. The basic characteristics, epidemiology, mixed infection and adenovirus genotypes of the patients were retrospectively analyzed. The patients diagnosed with adenovirus pneumonia (AP) were divided into two groups, severe AP (SAP) group and general AP(GAP) group according to the severity of illness. Mann-Whitney U test or χ2 test was used for comparison between groups, while multivariate regression was applied to analyze the risk factors of SAP. Results: Among 15 635 hospitalized children with respiratory tract infection, 467 cases were adenovirus positive, with a detection rate of 2.99%. Of the 467 patients with adenovirus infection, 284 were male and 183 female, the age was 2.4 (1.1,3.9) years, including 44 cases (9.4%) < 0.5 years, 59 cases (12.6%) of 0.5 to<1.0 years, 176 cases (37.7%) of 1.0 to <3.0 years, 150 cases (32.1%) of 3.0 to <7.0 years, and 38 cases (8.1%) of 7.0 to 14.0 years. Adenovirus infection was common in autumn and winter, and the high incidence months were October to December, which accounted for 51.6% (241/467) of the whole year cases. Co-infection was detected in 226 cases (48.4%) out of 467 patients, in which one pathogen co-infection was the most frequent form (172 cases, 76.1%). Of the 262 pathogen detected 108 (41.2%) were Mycoplasma pneumoniae. In 144 of ADV-positve cases (30.8%) were taken geno-typing was done by PCR amplification, the results showed that 74 cases (51.4%) were ADV 3, 7 subtypes and 65 cases (45.1%) of ADV 1, 2,6 subtypes. Of the 467 cases of ADV infection, 320 (68.5%) were diagnosed with pneumonia, 82 (17.6%) with upper respiratory tract infection and pharyngeal tonsillitis, and 65 (13.9%) with bronchitis, laryngeal bronchitis, and asthmatic bronchitis. Among the 320 patients with AP, 56 cases were severe and 264 cases were general. Two cases (3.6%) in severe group died. Compared with the GAP group, the age was young [17 (11,42) months vs. 24 (14,44) months, Z=2.222, P=0.026], the fever duration was long [8 (5,14) days vs. 6 (3,9) days, Z=3.380, P<0.01], and the proportions of preterm birth and having underlying diseases were high [respectively 19.6% (11/56) vs. 6.1% (16/264), 26.8% (15/56) vs. 10.2% (27/264), χ2=8.965,11.109, P<0.05] in SAP group. Referring to laboratory markers, white blood cell count, C-reactive protein, creatine kinase-MB and lactate dehydrogenase were significantly increased in SAP group as compared to GAP group(all P<0.05). Multivariate Logistic regression analysis showed that preterm birth (OR=3.284, 95%CI 1.079-9.993, P=0.036), underlying disease (OR=3.284, 95%CI 1.079-9.993, P=0.036), fever duration ≥10 d (OR=2.523,95%CI 1.195-5.328, P=0.015) and C-reactive protein ≥50 mg/L (OR=3.156, 95%CI 1.324-7.524, P=0.010) were positively correlated with the risk of SAP. Conclusions: The incidence of adenovirus infection among hospitalized children in Kunming was lower than the national level, and no outbreak occurred in 2019. Subtype 3 and 7 of ADV are the predominant strains for infection, which usually occurs in autumn and winter and mainly causes pneumonia. Premature birth, underlining diseases, long fever duration and markedly increased C-reactive protein are the risk factors for developing into severe pneumonia. This paper presents the prevalence and clinical characteristics of adenovirus infection in children at high altitude area.

Abstract
BACKGROUND Small cell lung cancer (SCLC) is the most aggressive form of lung cancer. The chemotherapy regimens and their efficacy in practice are seldom reported. We aimed to investigate treatment patterns and survival outcomes of patients with SCLC in Taiwan. METHODS Patients newly diagnosed with SCLC from 2011 to 2015 were identified from the Cancer Registry database. Their clinical characteristics, treatment regimens, and survival status were obtained from National Health Insurance Research database. The Kaplan-Meier method and Cox-proportional hazard model were used to analyze the survival outcomes. RESULTS Among a total of 2707 patients enrolled, 439 were in the limited stage (LS, 16.22%) and 2268 were in the extensive stage of the disease (ES, 83.78%). The median age was 66 and the majority were male (90.36%). The first-line regimen used for the patients was etoposide/cisplatin-based treatment, followed by etoposide/carboplatin-based regimen, and etoposide only. The median overall survival (OS) was 16.92 months (95% confidence interval [CI] 15.31-18.92) and 8.71 months (95% CI 8.38-9.07) in LS and ES patients, respectively. Chemotherapy regimen, Eastern Cooperative Oncology Group performance status, and history of radiotherapy were significant factors associated with OS. On the other hand, the major second-line treatment was a topotecan-based regimen (68.3%). However, this showed inferior survival outcome compared to etoposide-based regimen (5.09 months [95% CI 4.76-5.62] versus 8.77 months [95% CI 6.31-11.89], p < 0.001). CONCLUSION Etoposide is the preferred and superior first-line chemotherapy regimen in combination with platinum, and an alternative choice of second-line regimen for Taiwanese patients with SCLC.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory systemic disease characterized by persistent joint synovial inflammation and swelling, leading to cartilage damage and bone erosion. This retrospective, longitudinal study is to evaluate the treatment patterns of biologic-naïve RA patients receiving index biologic disease-modifying antirheumatic drug (bDMARD) and tofacitinib by the data of Taiwan National Healthcare Insurance Claims and the Death Registry between 2012 and 2017. Drug survival and treatment patterns were determined by investigating the occurrence of switching and discontinuation from index treatment. At baseline, 70.0% of patients used tumor necrosis factor inhibitors (TNFi) bDMARD with the majority taking etanercept (27.0%) or adalimumab (26.2%). During the follow-up period, 40.0% (n = 3,464) of index users switched (n = 1,479) or discontinued (n = 1,985) the treatment with an average incidence rate of 0.18 per patient-year. Among the six index treatment groups, drug survival was the lowest for adalimumab and highest for tocilizumab. When compared with etanercept, only adalimumab had a higher cumulative probability of switching/discontinuation (adjusted HR = 1.17, 95% CI: 1.08-1.28), whereas golimumab, non-TNFi bDMARDs and tofacitinib were significantly less probable to switch or discontinue. For patients switching the index treatment, tocilizumab (31.2%) and tofacitinib (23.4%) were the main regimens being switched to. In addition, 48.2% of patients who discontinued the index treatment received further retreatment, and 63.8-77.0% of them were retreated with same agent. In conclusion, this population-based study found that TNFi were the preferred agents as the index treatments during 2012-2017. Non-TNFi and tofacitinib were more common second-line agents being switched to. Nearly half of discontinued patients received retreatment, with a majority receiving the same agent.

Abstract
We aimed to evaluate factors influencing the outcomes of patients with platinum-sensitive recurrent epithelial ovarian carcinoma (EOC). Patients with advanced-stage EOC, who received debulking surgery and adjuvant chemotherapy for recurrence, were obtained from the National Health Insurance Research database of Taiwan between 2000 and 2013. A total of 1038 patients with recurrent advanced-stage EOC were recruited. The platinum + paclitaxel (PT) group had the best five-year overall survival (OS) compared with the other three groups (p < 0.001). The hazard ratios (HRs) of five-year OS for the platinum + liposomal doxorubicin (PD), topotecan (TOP), and pegylated liposomal doxorubicin (PLD) groups were 1.21 (p = 0.07), 1.35 (p = 0.016), and 1.80 (p < 0.001), respectively, compared with the PT group. The PT group also had lower hazard ratios of five-year OS for patients with platinum therapy-free interval (TFIp) between 6 and 12 months compared with the other three groups (p < 0.0001). However, the HRs of five-year OS did not differ between the PT and PD groups in patients with TFIp >12 months. Patients with TFIp >12 months had lower HRs of five-year OS compared with those with TFIp of 6–12 months, regardless of whether they were treated with platinum-based (p = 0.001) or non-platinum-based (p = 0.003) regimens. Chemotherapeutic regimens and TFIp influenced the outcomes of patients with recurrent EOC. For patients with TFIp of 6–12 months, the PT regimen is the first choice based on their best overall survival result. For patients with TFIp >12 months, either platinum-based or non-platinum regimens could be used because of their similar excellent overall survival.

Abstract
BACKGROUND/PURPOSE Atopic dermatitis (AD) is a common skin disease. At present, there is little evidence regarding its impact on patients' health-related quality of life (HRQoL) in Taiwan. Therefore, this study investigated the relationship between AD severity and patients' HRQoL in Taiwan. METHODS Patients with AD were recruited from three hospitals in Taiwan from April 2018 to April 2019. AD severity was measured using the Scoring of AD (SCORAD) scale, and HRQoL was assessed using the Dermatology Life Quality Index (DLQI) and the five-level version of EuroQol five-dimension questionnaire (EQ-5D-5L). RESULTS A total of 200 patients (mean age: 34.4 years) were recruited, including 103 males and 97 females. They were further classified as 79 mild, 72 moderate, and 58 severe AD patients according to their SCORAD scores. There was a positive correlation between their SCORAD and DLQI scores (Spearman's r = 0.77, p < 0.001). Patients with severe AD had higher scores in all the DLQI questions, particularly the symptoms, feelings, and work/school. In addition, both the EQ-5D visual analogue scale (VAS) scores and utility index values were negatively correlated with the SCORAD scores (Spearman's r = -0.46 and -0.60, respectively, both p < 0.001). Patients with higher AD severity had more problems with mobility, usual activity, pain/discomfort, and anxiety/depression, while demographic characteristics did not significantly affect HRQoL. CONCLUSION Higher AD severity is associated with poorer HRQoL in Taiwanese AD patients, with AD's effects on symptoms, feelings, and work/school being the most troublesome. Meanwhile, demographic factors did not affect HRQoL significantly.

Abstract
BACKGROUND Aristolochic acids (AA) and arsenic are chemical carcinogens associated with urothelial carcinogenesis. Here we investigate the combined effects of AA and arsenic toward the risk of developing upper tract urothelial carcinoma (UTUC). METHODS Hospital-based (n = 89) and population-based (2,921 cases and 11,684 controls) Taiwanese UTUC cohorts were used to investigate the association between exposure to AA and/or arsenic and the risk of developing UTUC. In the hospital cohort, AA exposure was evaluated by measuring aristolactam-DNA adducts in the renal cortex and by identifying A>T TP53 mutations in tumors. In the population cohort, AA exposure was determined from prescription health insurance records. Arsenic levels were graded from 0 to 3 based on concentrations in well water and the presence of arseniasis-related diseases. RESULTS In the hospital cohort, 43, 26, and 20 patients resided in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Aristolactam-DNA adducts were present in >90% of these patients, indicating widespread AA exposure. A>T mutations in TP53 were detected in 28%, 44%, and 22% of patients residing in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Population studies revealed that individuals who consumed more AA-containing herbs had a higher risk of developing UTUC in both arseniasis-endemic and nonendemic areas. Logistic regression showed an additive effect of AA and arsenic exposure on the risk of developing UTUC. CONCLUSIONS Exposure to both AA and arsenic acts additively to increase the UTUC risk in Taiwan. IMPACT This is the first study to investigate the combined effect of AA and arsenic exposure on UTUC.

Abstract
Longer survival in patients with multiple myeloma (MM) after treatment with novel agents (NA) such as thalidomide, bortezomib, and lenalidomide may be associated with increased risks of developing second primary malignancies (SPM). Few data describe the risk of SPM in patients with MM in Asia. This population-based retrospective cohort study assessed the risk of SPM in MM using the Taiwan National Cancer Registry and National Health Insurance Research databases from 2000 to 2014. Among 4,327 patients with newly diagnosed MM initiated with either novel agents alone (NA), chemotherapy combined with novel agents (CCNA), or chemotherapy alone (CA), the cumulative incidence of SPM overall was 1.33% at year 3. The SPM incidence per 100 person-years (95% confidence interval [CI]) was 0.914 (0.745–1.123) overall, 0.762 (0.609–1.766) for solid tumours, and 0.149 (0.090–0.247) for haematological malignancies. We compared risks of SPM using a cause-specific Cox regression model considering death as a competing risk for developing SPM. After controlling for age, gender, Charlson Co-morbidity Index, and time-period, the risk of developing any SPM or any haematological malignancy was significantly reduced in patients initiated on NA (2010–2014 period) compared to chemotherapy alone (adjusted hazard ratio 0.24, 95% CI 0.07–0.85, and 0.10, 95% CI 0.02–0.62, respectively). Contemporary treatment regiments using NA (mainly bortezomib) were associated with a lower risk for a SPM in comparison with CA.

Abstract
BACKGROUND Atopic dermatitis has been linked to increased risk of many comorbidities. However, the risks of certain comorbidities are still debated. OBJECTIVE To better characterize the basic demographics, treatment patterns, and associations between atopic dermatitis and comorbidities and to further investigate the influence of severity on comorbidities. METHODS We used a sample cohort of 999,992 people from the National Health Insurance Research Database of Taiwan to evaluate atopic dermatitis in the general population. RESULTS A total of 12,780 patients with atopic dermatitis in 2010 were identified. The prevalence was 1.28%. The proportions of severe and moderate cases were 7.43% and 19.26%, respectively. The most commonly used systemic treatment was corticosteroids. Compared with the general population, atopic dermatitis patients showed increased risks of all 9 groups of comorbidities, including autoimmune disorders, atopic disorders, chronic urticaria, ocular disorders, metabolic disorders, hypertensive disorders, ischemic heart disorders, cerebrovascular disorders, and psychiatric disorders. The severity and persistence of atopic dermatitis were correlated with the development of certain comorbidities. LIMITATIONS Miscoding and misclassification might have occurred, and only patients with active disease were enrolled. CONCLUSION Patients with atopic dermatitis have higher risks of various comorbidities. Comprehensive monitoring and treatment plans are needed to better manage these patients.

Abstract
The incidence of multiple myeloma (MM) is increasing worldwide, but the rate of increase is greatest in Asia. Few data describe the epidemiology and treatment of MM in Asia. Building on a cohort study from 2007 to 2012 using the Taiwan National Healthcare Insurance Research database, we extended our analysis to estimate the disease burden and treatment patterns of patients with MM in Taiwan through 2015. A further 1664 patients with newly diagnosed MM from 2013 to 2015 (total 4387 patients from 2007 to 2015) were enrolled and followed up until death or end of the observation period (December 31, 2016), whichever occurred first. The age distribution of the 2013–2015 cohort was similar to that for previous years, but there were fewer men (52.1% versus 58.0%), and more patients had renal impairment at diagnosis (19.7% versus 16.4%). From 2007 to 2015, crude annual incidences per 100,000 population of newly diagnosed MM increased from 1.74 to 2.48 and age-adjusted incidences from 1.41 to 1.65. Crude all-cause mortality rates increased over time. Case fatality decreased from 25.5 to 18.3% and median survival increased from 2.10 to 3.12 years. From 2007 to 2015, the percentage of patients receiving first-line therapy with novel agents increased from 0.4 to 89.4%, autologous stem cell transplantation doubled, and chemotherapy use decreased by 81%. Comprehensive national data covering 9 years of follow-up demonstrate continuing change in the disease burden, treatment, and survival of MM in Taiwan. Despite increased use of new treatments, MM remains largely incurable.

Abstract
This study investigated the predominant skin cancer subtype among organ transplant recipients, patients on chronic dialysis, and patients with chronic kidney disease in Asian subjects. Among 23,644 patients with skin cancer, identified from Taiwan Cancer Registry Database, 53 were organ transplant recipients, 255 were on chronic dialysis, 1,792 had chronic kidney disease, and 21,544 were in the control group. The proportions of squamous cell carcinoma were 52.8%, 47.8%, 40.1%, and 33.5%, respectively. Compared with the control group, organ transplant recipients (1.99-fold) and patients on chronic dialysis (1.25-fold) were at higher risk of developing squamous cell carcinoma than other skin cancers after adjustment for potential confounders. Subgroups or covariates associated with increased squamous cell carcinoma compared with other skin cancer risk included patients with chronic kidney disease aged < 70 years (vs. control group; 1.3-fold), old age (vs. young age; 2.8-fold), male sex (vs. female sex; 1.1-fold), and south Taiwan residency (vs. north Taiwan residency; 1.1-fold). Organ transplant recipients and patients on chronic dialysis had immune dysregulation, resulting in a higher risk of squamous cell carcinomas.

Abstract
Background: The therapy with biological disease-modifying anti-rheumatic drugs (bDMARDs) has proven to rapidly reduce articular symptoms/signs, decrease morbidities, and improve health outcome in patients with rheumatoid arthritis (RA) and be cost-effective in Western countries. However, the difference in healthcare utilization and costs between conventional synthetic DMARDs (csDMARDs) and bDMARDs in the treatment of RA patients in Taiwan remains largely unexplored. Methods: Two cohorts of RA patients and their matched controls were identified from the National Health Insurance Research database (NHIRD). The csDMARD cohort comprised of patients who submitted claims during 1997–2003 for cyclosporine≥50 mg/day with concomitant use of ≥2 csDMARDs for ≥28 days (n=1,569), whilst the bDMARD cohort comprised of patients who had ≥1 claim during 2003–2011 for bDMARD (n = 1,530). The per-patient per-year healthcare utilization and costs were estimated by bootstrapping method, with a comparison being undertaken between csDMARD and bDMARD. Results: The incremental number of hospitalization days was reduced from 2.3 days for csDMARD to 0.58 day for bDMARD. When compared to csDMARD-treated patients, the incremental total costs and RA-related medication costs were significantly higher in bDMARD-treated patients (US$9,081 vs. US$2,481; US$8,992 vs. US$1,883). However, the combined incremental healthcare utilization costs and non-RA medication costs were significantly lower in bDMARDs-treated patients compared to csDMARD-treated patients (US$374.7 vs. US$1,156.2). Conclusion: Although total costs increased as a result of introducing biologics in RA treatment, biologics have undoubtedly given rise to the benefits of reduced healthcare utilization. The increase in medication costs from biologics was offset by the lower costs of healthcare utilization. Our findings suggest that the medication costs of biologics may be alleviated by an improvement in clinical outcomes.

Abstract
BACKGROUND The prevalence of psychiatric comorbidities in patients with chronic urticaria (CU) in a national population is largely unknown. OBJECTIVES To investigate the prevalence of psychiatric disorders and psychiatric medication use in patients with CU in Taiwan. METHODS Data were sourced from Taiwan's National Health Insurance Research Database for 2011. Patients who had a primary/secondary International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of 708·1, 708·8 or 708·9 during 2011 with at least two outpatient visits and an antihistamine prescription were identified as CU cases. Patients with CU were classified into three disease severity groups according to their medication types. Psychiatric disorders were identified by patients having three outpatient visits with a primary or secondary diagnosis of a given psychiatric disease. Psychiatric medication use was defined by having at least four outpatient visits with prescriptions for anxiolytics, antidepressants or sleeping pills in 2010 or 2011. RESULTS Of the 167 132 patients with CU, 82·5% had mild CU, 17·0% had moderate CU and 0·4% had severe CU. Patients with CU had a higher prevalence of psychiatric disorders and psychiatric medication prescription than control groups. The relative risk (RR) of psychiatric disorders was 1·43 for patients with mild, 1·50 for patients with moderate and 2·32 for patients with severe CU vs. the controls (P < 0·001). For psychiatric medication prescription, the RRs were 1·95, 2·70 and 2·09, respectively, vs. controls (P < 0·001). CONCLUSIONS Patients with CU had a higher prevalence and risk of psychiatric disorders and psychiatric medication prescription than control groups. What's already known about this topic? Previous studies have shown a high prevalence of psychiatric comorbidities in patients with chronic urticaria (CU), with rates ranging from 35% to 60%. Anxiety, depression and somatoform disorders have been reported as the most prevalent mental disorders in patients with CU. What does this study add? Patients with CU had a higher prevalence of psychiatric disorders and psychiatric medication use than control groups in the general population. The relative risk (RR) of psychiatric disorders was 1·43 for those with mild CU, 1·50 for those with moderate CU and 2·32 for those with severe CU vs. controls. The RR for psychiatric medication use was 1·95 for those with mild CU, 2·70 for those with moderate CU and 2·09 for those with severe CU vs. controls. Mental health evaluations and management are important elements in CU management.

Abstract
Aims: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This analysis investigated the cost-effectiveness of the second-line treatment with tofacitinib, compared with adalimumab, both plus methotrexate (MTX), in patients with moderate-to-severe RA and an inadequate response to the first-line MTX, from a Taiwan National Health Insurance Administration perspective. Materials and methods: A patient-level simulation model was used to project lifetime costs and quality-adjusted life-years (QALYs). Base-case analysis compared second-line treatment with tofacitinib 5 mg twice daily plus MTX vs adalimumab 40 mg every 2 weeks plus MTX. Patients switched or discontinued treatment due to a lack or loss of effectiveness or a serious adverse event. Efficacy was measured by change in Health Assessment Questionnaire-Disability Index (HAQ-DI) score. HAQ-DI scores were used to predict mortality and resource utilization, and were mapped onto utility values to estimate QALYs. Efficacy and safety data were derived from clinical trials and other secondary sources. Uncertainty in model parameters was explored using one-way deterministic and probabilistic sensitivity analyses. Results: Patients gained 0.09 more QALYs with second-line tofacitinib plus MTX compared with adalimumab plus MTX (5.13 vs 5.04, respectively) at an additional cost of New Taiwan Dollars (NT$) 12,881. The incremental cost-effectiveness ratio was NT$143,122/QALY. One-way sensitivity analysis confirmed the base-case result was robust. Limitations: The lack of available clinical data, particularly for HAQ-DI scores, may introduce some bias in the analysis. No patients were in an early stage of RA, which may limit the generalizability of these results. Base-case results from our study are not necessarily generalizable to countries with healthcare systems that differ considerably from Taiwan. Conclusions: From a payer perspective, second-line treatment with tofacitinib plus MTX is a cost-effective treatment strategy, compared with adalimumab plus MTX, in patients with moderate-to-severe RA in Taiwan.

Abstract
Objective: Although disease-related malnutrition has prognostic implications for patients with chronic obstructive pulmonary disease (COPD), its health-economic impact and clinical burdens are uncertain. We conducted a population-level study to investigate these questions. Methods: We excerpted data relevant to malnutrition, prolonged mechanical ventilation and medications from claims by 1,197,098 patients which were consistent with COPD and registered by the Taiwan National Health Insurance Administration between 2009 and 2013. These patients were separated into cohorts with or without respiratory failure requiring long-term mechanical ventilation, and each cohort was divided to compare cases who developed malnutrition after their first diagnosis consistent with COPD, versus non-malnourished propensity-score matched controls. Results: The prevalence of malnutrition was 3.8% overall (10,259/287,000 non-ventilator-dependent; 1198/15,829 ventilator-dependent). Propensity-score matched non-ventilator-dependent patients who became malnourished (N = 10,242) had comparatively more hospitalizations, emergency room and outpatient visits, longer hospitalization (all p < .01), and higher mortality (HR = 2.26, 95% CI 2.18-2.34) than non-malnourished controls (N = 40,968). Malnourished ventilator-dependent patients (N = 1197) had higher rates of hospitalization, emergency room and outpatient visits, but shorter hospitalization (all p < .001) and lower mortality (HR = 0.85, 95% CI 0.80-0.93) than matched non-malnourished controls (N = 4788). Total medical expenditure on malnourished non-ventilator-dependent COPD patients was 75% higher than controls (p < .001), whereas malnourished ventilator-dependent patients had total costs 7% lower than controls (p < .001). Conclusions: Malnourishment among COPD patients who were not dependent on mechanical ventilation was associated with greater healthcare resource utilization and higher aggregate medical costs.

Abstract
AIM To examine the changes in the risks of death and cardiovascular diseases (CVD) in rheumatoid arthritis (RA) patients treated with conventional synthetic or biologic disease-modifying antirheumatic drugs (csDMARD or bDMARD) during 1997-2013. METHODS Two cohorts of RA patients and their matched controls were identified from the National Health Insurance Research database. There were 1569 patients in the csDMARD cohort who received cyclosporine ≥50 mg/d with concomitant usage of ≥2 csDMARDs during 1997-2003. There were 1530 patients in the bDMARD cohort if patients had ≥1 claim for bDMARD during 2003-2011. Adjusted hazard ratios (aHRs) for the risk of death, myocardial infarction, and stroke, were assessed using the Kaplan-Meier survival curves and the Cox proportional hazards models. RESULTS Compared with matched cohorts, the incidence of death was higher with csDMARD with a more than 6-fold increase (csDMARD vs controls: 33% vs 5%); while it only increased with a much smaller magnitude with bDMARD (bDMARD vs controls: 15% vs 11%). In addition, an increase in the reduction of incidence rate of stroke with bDMARD (bDMARD vs controls: 2% vs 5%) than that with csDMARD (csDMARD vs controls: 3% vs 4%) was found. Results from multivariate analysis showed that RA patients receiving bDMARD had a significantly lower increase in the risk of deaths (aHR 1.05; 95% CI 0.84-1.33) compared with those receiving csDMARD (aHR 8.75; 95% CI 7.43-10.31). In addition, bDMARD was associated with a higher reduction in the risk of stroke compared with csDMARD (bDMARD: aHR 0.37; 95% CI 0.22-0.62; csDMARD: aHR 0.73; 95% CI 0.51-1.05). CONCLUSION Biologics used in RA patients have been shown to have a beneficial impact on improving clinical outcomes, including decreased risks of death and stroke. The economic burden from costs of biologics may be alleviated by improving outcomes.

Abstract
Objective: Three vaccines are available to Taiwanese young girls for cervical cancer (CC) prevention. Here we evaluate the cost-effectiveness of the two-dose (2D) AS04-adjuvanted HPV-16/18 vaccine (2D-AS04-HPV-16/18v)+screening compared with a screening programme alone, with 2D human papillomavirus 6/11/16/18 vaccine (2D-4vHPVv)+screening, and with 2D/three-dose (3D) human papillomavirus 6/11/16/18/31/33/45/52/58 vaccine (9vHPVv)+screening, for Taiwan universal mass vaccination. Methods: A static Markov cohort model simulated the natural history of human papillomavirus (HPV) infection and CC screening for a 12-year-old cohort of Taiwanese girls (N=120,000). The model ran in 1-year cycles over the cohort’s lifetime. Vaccine efficacy irrespective of HPV type was considered in the analysis for each vaccine. Input data were obtained from published literature, local databases, government reports and websites, and expert opinion. The analysis incorporated direct medical costs only, with an annual discount rate of 3.0%. The threshold was determined as 1 Gross Domestic Product per capita (New Taiwan dollar [NT$] 727,818; year 2016). Results: The 2D-AS04-HPV-16/18v+screening yielded 0.0365 quality-adjusted life year (QALY) gained at an additional cost of NT$ 5,770 per person compared with the screening programme alone. This resulted in an incremental cost-effectiveness ratio well below the threshold. Compared with 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening, discounted results demonstrated additional QALYs gained at lower cost for 2D-AS04-HPV-16/18v+screening, making it dominant over both 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening. Conclusions: Vaccinating Taiwanese girls with 2D-AS04-HPV-16/18v in addition to screening to prevent CC is cost-effective compared with using a screening programme alone and the dominant option compared with 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening.

Abstract
Background There is still significant uncertainty as to whether market competition raises or lowers clinical quality in publicly funded healthcare systems. We attempted to assess the effects of market competition on inpatient care quality of stroke patients in a retrospective study of the universal single-payer health insurance system in Taiwan. Methods In this 11-year population-based study, we conducted a pooled time-series cross-sectional analysis with a fixed-effects model and the Hausman test approach by utilizing two nationwide datasets: the National Health Insurance Research Database and the National Hospital and Services Survey in Taiwan. Patients who were admitted to a hospital for ischemic or hemorrhagic stroke were enrolled. After excluding patients with a previous history of stroke and those with different types of stroke, 247 379 ischemic and 79 741 hemorrhagic stroke patients were included in our analysis. Four outcome indicators were applied: the in-hospital mortality rate, 30-day post-operative complication rate, 14-day re-admission rate and 30-day re-admission rate. Results Market competition exerted a negative or negligible effect on the medical care quality of stroke patients. Compared to hospitals located in a highly competitive market, in-hospital mortality rates for hemorrhagic stroke patients were significantly lower in moderately (β = -0.05, P < 0.01) and less competitive markets (β = -0.05, P < 0.01). Conversely, the impact of market competition on the quality of care of ischemic stroke patients was insignificant. Conclusions Simply fostering market competition might not achieve the objective of improving the quality of health care. Other health policy actions need to be contemplated.

Abstract
Pretreatment with statins is associated with improved outcomes in severe sepsis, acute coronary syndrome, and stroke. Patients with cardiac arrest experience sepsis-like syndrome and ischemia reperfusion injuries in the heart and brain. The objective of this study was to investigate the effects of statin use before cardiac arrest on outcomes in cardiac arrest patients. Medical records of 142,131 adult patients who experienced nontraumatic cardiac arrest and were resuscitated between 2004 and 2011 were analyzed. Patients were grouped into 2 groups: the "statin group" comprised patients who had received statin treatment for at least 30 days before the cardiac arrest event; the "never statin group" comprised patients who had no statin use within 30 days before the event. Patients with previous statin treatment had better chance of survival to hospital discharge (6.1% vs 4.3%, p <0.0001) and 1-year survival (4.8% vs 3.2%, p <0.0001) after propensity score matching. Previous statin use was an independent predictor for 1-year survival (adjusted odds ratio 1.41, 95% confidence interval 1.16 to 1.71; p = 0.001). A favorable outcome effect of statin on 1-year survival was observed in the presence of diabetes mellitus, chronic kidney disease, and Charlson Comorbidity Index score greater than 5 in the subgroup analysis. In conclusion, statin use before cardiac arrest is associated with 1-year survival in a propensity score-matched nationwide cohort study.

Abstract
BACKGROUND The aim of this study was to assess the association between various classes of antidepressants and the risk of medication noncompliance as well as suicidal behavior among depressed patients. METHODS A retrospective cohort study was conducted utilizing two nationwide population-based datasets in Taiwan from 2010 to 2016. The outcome measures included the risk of medication noncompliance, attempted suicide, and completed suicide. Cox proportional hazards models with stratification of the propensity score deciles were performed. RESULTS A total of 447,411 new antidepressant users were identified. Compared to SSRIs, patients who received SARIs [adjusted hazard ratio (aHR) = 1.124, 95% confidence interval (CI) = 1.108-1.142], SNRIs (aHR = 1.049, 95% CI = 1.033-1.065), and other classes of antidepressants (aHR = 1.037, 95% CI = 1.024-1.051) were more likely to exhibit poor medication noncompliance. Patients who received SNRIs had a higher risk of attempted suicide (aHR = 1.294, 95% CI = 1.114-1.513), compared to SSRIs. However, patents in the TCAs group revealed the opposite result (aHR = 0.543, 95% CI = 0.387-0.762). Concerning the risk of completed suicide, this analysis detected no statistical significance across different types of antidepressants. LIMITATIONS Although the universal coverage of Taiwan's national health insurance program tends to minimize the risk of selection and recall bias, it is difficult to rule out medical surveillance bias by using claim data. CONCLUSIONS This study demonstrated that classes of antidepressants exert different degrees of impact on the risk of medication noncompliance and attempted suicide, but not completed suicide, among depressed patients.

Abstract
OBJECTIVES The total medical (economic) costs of haemodialysis (HD) and peritoneal dialysis (PD), including direct medical costs, out-of-pocket (OOP) costs and productivity losses, have become an important issue. This study aims to compare the direct non-medical costs and indirect medical costs of both modalities in Taiwan. DESIGN AND SETTING This multicentre study included cross-sectional interviews of patients over 20 years old and articulate, who had been continuously receiving long-term HD or PD for more than 3 months between April 2015 and March 2016. Mann-Whitney U test, Wilcoxon rank-sum test and 1000 bootstrap procedures with replacement were used for analysis. OUTCOME MEASURES Differences in OOP costs and productivity losses. RESULTS There were 308 HD and 246 PD patients available for analysis. HD patients had significantly higher monthly OOP costs than PD patients after bootstrap procedures (NTD 5912 vs NTD 5225, p<0.001; NTD, new Taiwan dollars; 1 US dollar=30 NTD). Compared with PD patients, HD patients had higher monthly productivity losses after bootstrap procedures (NTD 14 150 vs NTD 11 611, p<0.001), resulting from more time spent seeking outpatient care (HD, 70.4 hours vs PD, 4.4 hours, p<0.001) and time spent by family caregivers for outpatient care (HD, 66.1 hours vs PD, 6.1 hours, p<0.001). The total costs per patient-month of HD and PD modalities, including OOP costs and productivity losses, were NTD 20 062 and NTD 16 836, respectively. CONCLUSIONS The HD modality has higher OOP costs and productivity losses than the PD modality in Taiwan.
