RESUMEN
This study aimed to investigate the factors influencing physicians use of the PharmaCloud system in Taiwan through Technology Continuance Theory (TCT) and to construct a TCT-based structured questionnaire to demonstrate the attitude and behavior of physicians in the Taiwanese medical system. It focused on investigating "confirmation", "perceived usefulness", "perceived ease of use", "attitude", "satisfaction", and "continuance intention" towards the preload-based comparison and manual search in PharmaCloud by attending physicians during their outpatient clinics. Path analysis was used to analyze the cause and effect relationship between variables. This study collected 528 valid questionnaires and the results of path analysis found that factors affecting physicians' continued use of preload-based comparison in PharmaCloud included "perceived usefulness", "satisfaction", and "attitude" (all p < 0.001); however, factors that influenced physicians' continued use of manual search in PharmaCloud were only "satisfaction" and "attitude" (all p < 0.001). Additionally, the effects of "perceived usefulness" and "perceived ease of use" on "satisfaction" could only be seen in preload-based comparison in PharmaCloud. In conclusion, when physicians' actual use of PharmaCloud met their expectations, physicians had higher levels of confirmation and better perceived usefulness, which naturally increased their satisfaction and attitude towards PharmaCloud and positively prompted them to continue using it.

This study is conducted to investigate the association between major depressive disorder and the subsequent development of Alzheimer disease (AD) in elderly patients with different health statuses using Taiwan's National Health Insurance Research Database (NHIRD).A retrospective cohort study was performed on subjects over 65 years old from 2002 to 2006 using a random sampling from the 1 million beneficiaries enrolled in the NHI. Patients who were diagnosed with major depressive disorder were selected as the case group. Subjects in the control group were selected from elderly patients who did not have depression during the study period by matching age, sex, and index date of depression with subjects in the case group using a ratio of 1:4 (case:control). Both groups of patients were checked annually over a period of 7 years to observe whether they subsequently developed AD.A total of 1776 subjects were included in the case group while 7104 subjects were in the control group. After the follow-up period, 59 patients (3.3%) with depression developed AD while 96 patients (1.4%) without depression developed AD. The Kaplan-Meier curves showed that the incidence rate of AD in both groups varied significantly depending on different health statuses (log-rank Pâ<â.001). Results of the generalized estimating equation model found that patients with depression (hazard ratio [HR]â=â1.898; 95% confidence interval [CI]â=â1.451-2.438), very severe health status (HRâ=â1.630; 95% CIâ=â1.220-2.177), or artery diseases (HRâ=â1.692; 95% CIâ=â1.108-2.584) were at a higher risk of developing AD than other groups.The association between major depressive disorder and the later development of AD varied depending on the health statuses of elderly patients. Clinicians should exercise caution when diagnosing and treating underlying diseases in elderly depressed patients, and then attempt to improve their health status to reduce the incidence rate of subsequent AD development.

OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of the long-acting beta-2 agonist (LABA)/long-acting muscarinic antagonist (LAMA) dual bronchodilator indacaterol/glycopyrronium (IND/GLY) as a maintenance treatment for COPD patients from the perspective of health care payer in Taiwan. PATIENTS AND METHODS: We adopted a patient-level simulation model, which included a cohort of COPD patients aged ≥40 years. The intervention used in the study was the treatment using IND/GLY, and comparators were tiotropium or salmeterol/fluticasone combination (SFC). Data related to the efficacy of drugs, incidence of exacerbation, and utility were obtained from clinical studies. Direct costs were estimated from claims data based on the severity of COPD. The cycle length was 6 months (to match forced expiratory volume in 1 second [FEV1] data), and the time horizons included 1, 3, 5, 10 years, and lifetime. Deterministic and probabilistic sensitivity analyses were conducted to test the robustness of the model results. Costs were expressed in US dollars with a discount rate of 3.0%. RESULTS: Compared to tiotropium and SFC, the incremental cost-effectiveness ratios (ICERs) per quality-adjusted life year (QALY) gained of patients treated with IND/GLY were US$5,987 and US$14,990, respectively. One-way sensitivity analysis revealed that the improvement in FEV1 provided by IND/GLY, the distribution of patients with regard to the severity of COPD, and acute exacerbation rate ratio were the key drivers behind cost-effectiveness. Adopting a willingness to pay of US$60,000 per QALY gained as the threshold, there was a 98.7% probability that IND/GLY was cost-effective compared to tiotropium. Similarly, there was a 99.9% probability that IND/GLY was cost-effective compared to SFC. CONCLUSION: As a maintenance treatment for COPD, we consider the dual bronchodilator IND/GLY as a cost-effective strategy when compared to either tiotropium or SFC.

BACKGROUND: To assess the utilization of and satisfaction with ophthalmic healthcare provided by integrated delivery system (IDS) since 2000 and vision-related quality of life (VRQoL) for residents of an offshore island of Taiwan. METHODS: Facilitators interviewed residents (age ≥ 50 years) with the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) for VRQoL and a questionnaire on clinical information, ophthalmic care utilization and satisfaction. RESULTS: A total of 841 participants (response rate 93.4 %, 841/900) completed the questionnaire survey. Mean age was 63.7 (±10. 7) years. The common eye diseases were cataract (44.7 %), dry eye (15.5 %), and glaucoma (8.7 %). Among the participants, 61.0 % sought ophthalmic care under the IDS in the past year and 17.6 % experienced unmet ophthalmic needs in the past 6 months. Satisfaction with ophthalmic care under the IDS was 88.1 %. Determinants of dissatisfaction under the IDS were distance to healthcare facility and VRQoL. Predictors of VRQoL included age, residential area, marital status, occupation, comorbid condition, commercial insurance, household income, cataracts and glaucoma. CONCLUSIONS: The implementation of IDS improves accessibility of ophthalmic care for residents of an offshore island. Geographic proximity to avail healthcare facility and VRQoL affect satisfaction with the IDS.

Objective To measure therapeutic inertia by characterizing prescription patterns using secondary data obtained from the nationwide diabetes mellitus pay-for-performance (DM-P4P) programme in Taiwan. Methods Using reimbursement claims from Taiwan's National Health Insurance Research Database, a nationwide retrospective cohort study was undertaken of patients with diabetes mellitus who participated in the DM-P4P programme from 2006-2008. Glycosylated haemoglobin results were used to evaluate modifications in therapy in response to poor diabetes control. Prescription patterns were used to assign patients to either a therapeutic inertia group or an intensified treatment group. Therapeutic inertia was defined as the failure to act on a known problem. Results The research sample comprised of 168 876 patients with diabetes mellitus who had undergone 899 135 tests. Of these, 37.4% (336 615 visits) of prescriptions were for a combination of two types of drug and 27.7% (248 788 visits) were for a combination of three types of drug. The proportion of patients in the intensified therapy group who were prescribed more than two types of drug was considerably higher than that in the therapeutic inertia group. Conclusion In many cases in the therapeutic inertia group only a single type of hypoglycaemic drug was prescribed or the dosage remained unchanged.

BACKGROUND: Colorectal cancer (CRC) is a leading cause of cancer-related deaths in developed countries and its incidence increases with age. Intravenous administration of bolus 5-fluorouracil (5-FU) and leucovorin (LV) has been a standard treatment regime for stage III CRC. However, patients generally prefer oral therapy such as Capecitabine. Studies showed that combination of oxaliplatin and capecitabine demonstrated efficacy and safety on par with treatment involving various 5-FU/LV-based regimens in elderly patients as they are in younger ones. However, little is known regarding the cost of adjuvant therapy or the effect of therapy on HRQoL. Thus the aims of this study were to evaluate the influence of different adjuvant care for stage III CRC on the HRQoL of elderly patients and to compare the economic costs associated with capecitabine-based and 5-FU/LV-based adjuvant treatments from a societal perspective in Taiwan. METHODS: A prospective, open-label, observational, multicenter study involving 123 patients aged 70 and over from 11 different centers was conducted between July 2008 and July 2011 in Taiwan. The adjusted monthly costs per patient and HRQoL were evaluated from individual-level data. The HRQoL of patients was assessed before and after adjuvant treatment. Direct and indirect costs of adjuvant treatment were estimated from a number of sources, and QoL scores were compared between groups. RESULTS: After correcting for baseline characteristics of patients, no significant differences were observed in the global HRQoL scores between treatment groups during the study period. According to QLQ-CR38 results, capecitabine-based therapy appeared to alleviate problems related to defecation (4.54 vs. 8.5; P = 0.011); however, micturition problems increased (9.27 vs. 7.51; P = 0.04), compared with 5-FU/LV-based treatment. The adjusted monthly treatment cost per patient was NT$27,300 for capecitabine-based treatment and NT$53,671 for 5-FU/LV-based treatment. The total cost of 5-FU/LV-based treatment was 59 % greater than that of capecitabine-based treatment. CONCLUSIONS: Analyzing from the societal perspective in Taiwan, capecitabine-based therapy incurred lower treatment costs than 5-FU/LV-based therapy and did not jeopardize HRQoL. Therefore, capecitabine, with or without oxaliplatin, could be considered as an alternative treatment option for elderly patients with stage III CRC.

PURPOSE: The purpose of this study was to compare health-related quality of life (HRQoL) and costs associated with 2 adjuvant chemotherapy regimens [capecitabine-based therapy versus 5-fluorouracil/leucovorin (5-FU/LV)-based therapy] in stage III colorectal cancer patients. METHODS: We conducted a prospective, open-label, observational, multicenter study from July 2008 to July 2011. The European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires was used to assess HRQoL before, during, and after treatment. The direct and indirect costs of adjuvant treatment were estimated from a specially prepared questionnaire, the National Health Insurance Research Database, and other published sources. We used propensity scoring to match samples between groups and performed multivariate analyses to adjust for differences in patient demographics and clinical characteristics. RESULTS: A total of 497 patients were enrolled, and 356 completed the surveys. Following propensity score matching, 239 patients were included in the analysis (122 in the capecitabine-based group, 117 in the 5-FU/LV-based group). Global HRQoL scores did not differ significantly between the two groups. However, compared to patients in the 5-FU/LV-based group, patients in the capecitabine-based group had less nausea and vomiting (mid-term, P = 0.024; final, P = 0.013), appetite loss (mid-term, P < 0.0001; final, P = 0.001), and fewer side effects from chemotherapy (mid-term, P = 0.017). In addition, the monthly cost of capecitabine-based therapy was lower than those of 5-FU/LV-based therapy [NT$31,895.46 (US$1063.18) vs. NT$79,159.24 (US$2638.64) per patient]. CONCLUSIONS: Capecitabine is a reasonable alternative and cost-effective treatment option under current conditions for patients with stage III colorectal cancer.

OBJECTIVES: To assess the cost-effectiveness of oral capecitabine compared with intravenous bolus 5-fluorouracil/leucovorin (5-FU/LV) in the adjuvant treatment of stage III colon cancer in Taiwan from payer (Bureau of National Health Insurance [BNHI]) perspectives. METHODS: A health state-transition model was developed to estimate the incremental costs and effectiveness of capecitabine versus 5-FU/LV. The time horizons studied were: treatment duration (24 weeks) plus 36 months, 48 months, 60 months, 120 months, and lifetime. Costs were expressed in Taiwanese new dollars (NT$). Clinical outcomes, medical resource use, and utilities were extracted from published sources. Unit costs were estimated from BNHI fee schedules, published sources, and local expert opinion. Outcomes and future costs were discounted at 3%. Cost-effectiveness was expressed as cost per quality-adjusted life-month (QALM). The effects of uncertainty were explored through a one-way sensitivity analysis. RESULTS: For the 24-week time period, drug acquisition costs were higher for capecitabine than 5-FU/LV (NT$114,405 vs. NT$4,904 per patient); however, these were offset by the higher administration costs of 5-FU/LV (NT$2,573 vs. NT$204,201 per patient). Overall direct costs for the 24-week treatment period were less with capecitabine than 5-FU/LV (NT$129,327 vs. NT$233,873 per patient). Cost savings with capecitabine were also evident when longer time horizons were considered. Over a lifetime, the projected survival benefit for capecitabine was 7 QALMs. CONCLUSIONS: From the perspectives of the BNHI and society in Taiwan, capecitabine not only saves costs but also improves health outcomes compared with 5-FU/LV in the adjuvant treatment of stage III colon cancer.
