We conducted a retrospective population-based, matched cohort study using the National Health Insurance Research Database to estimate healthcare resource utilisation (HRU) and costs in patients with newly diagnosed AL amyloidosis in Taiwan. Cases were matched 10:1 by age, sex, and area of residence to patients without AL amyloidosis (comparators) randomly selected from the database during the same time period. Annual all-cause HRU and costs for 3 years were quantified. AL amyloidosis-attributable costs were obtained by subtracting all-cause HRU costs incurred by comparators from cases. The mean age of all patients was 60.78 years and 59.07% were male. Co-morbidities were more frequent in cases than comparators. By 6 months after diagnosis, 12.1% of cases had died versus 0.9% of comparators. In the first year, cases had 103% more outpatient visits, 177% more emergency room visits, were hospitalised 4-times more frequently, and spent 5.5-times more days in hospital than comparators, and total healthcare costs were > sixfold higher. Costs incurred during the first year after diagnosis accounted for 55% of the 3-year cumulative cost. High HRU costs associated with delayed diagnosis and end-organ damage indicate a need for earlier diagnosis and more effective treatments for AL amyloidosis. [ABSTRACT FROM AUTHOR]

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.

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.

Objectives: This nationwide population-based study aimed at evaluating healthcare resource utilization and direct medical costs among rheumatoid arthritis (RA) patients receiving biologic therapies in Taiwan. Design and setting: A retrospective cohort of 2,425 RA patients who had received first-line tumor necrosis factor (TNF)-α antagonist treatment for at least 6 months (the baseline period) between 2007 and 2011 was identified from the National Health Insurance Research Database in Taiwan. Outcome measures: Healthcare resource utilization and direct medical costs of those patients were analyzed and compared 1 year before the index date and during the 1-year follow-up. Results: Analytical results demonstrated that 87.7% of RA patients received the same TNF-α antagonist during the 1-year follow-up, 2.4% of the patients switched to another TNF-α antagonist after the baseline period, 7.1% of the study cohort received a second-line biologic agent, while the remaining patients discontinued use of any TNF-α antagonist. Compared to 1 year before the index date, there were significant reductions in emergency room visits and hospitalization days for RA patients treated with the same TNF-α antagonist during the 1-year follow-up. However, there was an increase of outpatient visits among those patients. For those RA patients who switched to another TNF-α antagonist or received a second-line biologic agent, they consumed more healthcare resources. Furthermore, the corresponding medication costs went up markedly during the 1-year follow-up, but nearly all total direct medical costs (biologics excluded) were significantly reduced across the study cohort. Lastly, male patients incurred slightly higher medical costs than their counterparts, albeit in a statistically insignificant fashion. Conclusions: This investigation revealed that RA patients treated with biologics utilized fewer emergency room visits and shorter hospitalization days, but incurred higher costs. In summary, this study provides meaningful information on healthcare resource utilization and medical costs of RA patients for healthcare providers and policymakers. [ABSTRACT FROM AUTHOR]

Objectives: To better understand the economic burden of gout patients in Taiwan, a nationwide retrospective study was conducted to compare the healthcare costs and utilization between gout and gout-free patients.Methods: The Longitudinal Health Insurance Database (LHID) 2010 was used to identify gout cases and matched gout-free controls. Gout cases were defined as having (1) at least three instances of diagnoses of gout on medical claims, or (2) one diagnosis of gout with at least one gout-related pharmacy claim in 2011. A control cohort was matched with cases at a 3:1 ratio by age, gender, residential area, and the Charlson Comorbidity Index. All medical utilization and costs per patient within the 365 days following the index date were compared between cases and controls.Results: Out of 993,332 beneficiaries, a total of 21,376 matched gout patients met the gout inclusion criteria. Compared to controls, gout patients had more outpatient visits (mean = 31.2 vs 22.6), inpatient visits (mean = 1.7 vs 1.5), and ER visits (mean = 1.9 vs 1.7) (all p < .0001), as well as more outpatient costs (median = USD $634 vs $404), inpatient costs (median = USD $1330 vs $1254), and ER costs (median = USD $87 vs $89) (all p < .05).Conclusion: Gout patients had higher medical utilization and costs than gout-free patients. In gout patients, all-cause and gout-related utilization were mostly outpatient visits, whereas most of the all-cause and gout-related costs were due to hospitalization. The study findings could be useful for future economic evaluations and healthcare resource allocation. [ABSTRACT FROM AUTHOR]

Background: Disease-related malnutrition is highly prevalent, and has prognostic implications for patients with chronic kidney disease (CKD); however, few studies have investigated the impact of malnutrition, or protein-energy wasting (PEW), on healthcare utilization and medical expenditure among CKD patients.Methods: Using claim data from the National Health Insurance in Taiwan, this study identified patients with CKD between 2009-2013 and categorized them into those with mild, moderate, or severe CKD. Cases with PEW after CKD was diagnosed were propensity-score matched with controls in a 1:4 ratio. Healthcare resource utilization metrics were compared, including outpatient and emergency department visits, frequency and duration of hospitalization, and the cumulative costs associated with different CKD severity.Results: From among 347,501 CKD patients, eligible cohorts of 66,872 with mild CKD (49.2%), 27,122 with moderate CKD (19.9%), and 42,013 with severe CKD (30.9%) were selected. Malnourished CKD patients had significantly higher rates of hospitalization (p < .001 for all severities) and re-admission (p = .015 for mild CKD, p = .002 for severe CKD) than non-malnourished controls. Cumulative medical costs for outpatient and emergency visits, and hospitalization, were significantly higher among all malnourished CKD patients than non-malnourished ones (p < .001); total medical costs were also higher among malnourished patients with mild (62.9%), moderate (59.6%), or severe (43.6%) CKD compared to non-malnourished patients (p < .001).Conclusions: In a nationally-representative cohort, CKD patients with PEW had significantly more healthcare resource utilization and higher aggregate medical costs than those without, across the spectrum of CKD: preventing PEW in CKD patients should receive high priority if we would like to reduce medical costs.

Background Migraine is associated with a significant economic burden in Western countries. However, there is limited information regarding the impact of the cost of migraine in Asia. Objectives To quantify and compare the direct medical costs of refractory migraine ( RM) and other migraine, using health insurance claims data in Taiwan. Methods A retrospective matched case-control study was conducted utilizing data from the Taiwan National Health Insurance Research Database. RM cases were defined as patients with at least 1 neurological outpatient visit with a primary or secondary International Classification of Diseases, Ninth Revision, Clinical Modification code of 346.11 (common migraine with intractable migraine, so stated), diagnosed by certified neurologists in medical centers during 2007-2008. The first control group was the non-migraineurs matched with cases at a 4:1 ratio by age, gender, urbanization level of the residence, and income. The second control group was patients with other migraine types (346.00, 346.10, 346.20, 346.80, and 346.90) matched with cases at a 4:1 ratio by age, gender, and hospital setting. Medical utilization and costs within 365 days after the index visit date were assessed using a 2-part model. The exchange rate for US$1 was NT$32.50. Results Patients with RM had significantly higher total medical costs compared with non-migraineurs ( NT$57,932 [ US$1783] vs NT$26,817 [ US$825]; P < .001) or other migraineurs ( NT$54,678 [ US$1682] vs NT$38,397 [ US$1181]; P < .001). The mean drug costs for those with RM were also higher than for non-migraineurs ( NT$19,752 [ US$608] vs NT$8660 [ US$266]; P < .001) or those with other migraine ( NT$17,623 [ US$542] vs NT$10,088 [ US$310]; P < .001). In addition, we reviewed the charts of all patients with an outpatient department diagnostic code of 346.11 (n = 98) at our hospital ( Taipei Veterans General Hospital, a medical center in Taiwan) in 2007. Of these patients, 88 (90%) fulfilled the Silberstein- Lipton criteria for chronic migraine, ie, >15 headache days per month and presence of a history of migraine. Conclusions Refractory migraineurs in Taiwan had significantly higher medical costs than either non-migraineurs or those with other migraine diagnoses. [ABSTRACT FROM AUTHOR]

Abstract: Background: Bipolar disorder (BD) is a costly disease with a high rate of vasculometabolic comorbidities. The aims of this study were to explore the 1-year treatment cost, including total medical and non-psychiatric services, and the prevalence of vasculometabolic comorbidities in individuals with BD. Methods: A nationwide population-based dataset, covering the years 2006 and 2007, was obtained from the Taiwan National Health Insurance claims database. The study sample comprised patients discharged from hospitals between 1 January 2006 and 31 December 2007. Annual non-psychiatric and total medical costs and vasculometabolic comorbidities were examined. Generalized linear models were used to examine the medical costs, and conditional logistic regression analyses were carried out to test the prevalence of vasculometabolic comorbidities in people with BD and to compare this with that found in matched controls. Results: The total medical cost was 11-fold higher (New Taiwan [NT] $227,040 vs. NT$20,461), and the non-psychiatric medical cost was 1.7-fold higher (NT$33,173 vs. NT$19,406) with regard to the individuals with BD vs. the matched controls. The prevalence of vasculometabolic comorbidities was significantly higher in the individuals with BD than in the controls (ratio ranging from 1.86 to 4.06). Conclusions: Both the non-psychiatric healthcare utilization and the prevalence of vasculometabolic comorbidities are higher with regard to individuals with BD vs. their matched controls. Therefore, treatment of BD should integrate medical and psychiatric care to decrease the impact of medical comorbidities, which may also decrease the overall medical cost. [Copyright &y& Elsevier]

Tang C-H, Hsieh MH, Hung S-T, Lee IH, Lin Y-J, Yang YK. One-year post-hospital medical costs and relapse rates of bipolar disorder patients in Taiwan: a population-based study. Bipolar Disord 2010: 12: 859-865. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. We examined a nationwide population-based dataset of patients with bipolar disorder (BD) hospitalized in Taiwan, with our analyses focusing on one-year medical costs and relapse rates. The data for this study, covering the years 2006 and 2007, were obtained from the Taiwan National Health Insurance (NHI) claims database. The study sample comprised BD patients who were discharged from hospitals between January 1 and December 31, 2006. Annual medical costs and relapse rates were described; the Kaplan-Meier method and the generalized linear models were carried out to examine the risk factors associated with cases of relapse. The annual medical costs associated with relapses among the study sample were found to be approximately 7.6 times the average per-capita NHI expenditure in Taiwan in 2006 (US$4,354 versus US$574), with a one-year relapse rate of 55%. Those patients between 20 and 60 years old with a medication possession ratio of <80 and with depressive episodes during the recruitment period were identified as being at risk of relapse. Bipolar disorder, which is a very costly disease, is associated with both poor medication adherence rates and frequent recurrences. Targeting drug adherence issues during maintenance treatment may well provide a valuable opportunity to reduce the risk of such recurrences. [ABSTRACT FROM AUTHOR]

Objective To elicit a patient’s willingness to participate in a diabetes pay-for-performance for patient (P4P4P) program using a discrete choice experiment method. Methods The survey was conducted in March 2013. Our sample was drawn from patients with diabetes at five hospitals in Taiwan ( International Classification of Diseases, Ninth Revision, Clinical Modification code 250). The sample size was 838 patients. The discrete choice experiment questionnaire included the attributes monthly cash rewards, exercise time, diet control, and program duration. We estimated a bivariate probit model to derive willingness-to-accept levels after accounting for the characteristics (e.g., severity and comorbidity) of patients with diabetes. Results The preferred program was a 3-year program involving 30 minutes of exercise per day and flexible diet control. Offering an incentive of approximately US $67 in cash per month appears to increase the likelihood that patients with diabetes will participate in the preferred P4P4P program by approximately 50%. Conclusions Patients with more disadvantageous characteristics (e.g., elderly, low income, greater comorbidity, and severity) could have less to gain from participating in the program and thus require a higher monetary incentive to compensate for the disutility caused by participating in the program’s activities. Our result demonstrates that a modest financial incentive could increase the likelihood of program participation after accounting for the attributes of the P4P4P program and patients’ characteristics.
