RESUMEN
BACKGROUND: The increasing trend of multiple chronic conditions across the world has worsened the problem of medication duplication in health care systems without gatekeeping or referral requirement. Thus, to overcome this problem, a reminder letter has been developed in Taiwan to nudge patients to engage in medication management. OBJECTIVE: To evaluate the effect of reminder letter on reducing duplicated medications. RESEARCH DESIGN: A 2-arm randomized controlled trial design. SUBJECTS: Patients with duplicated medications in the first quarter of 2019. MEASURES: The Taiwanese single-payer National Health Insurance Administration identified the eligible patients for this study. A postal reminder letter regarding medication duplication was mailed to the patients in the study group, and no information was provided to the comparison group. Generalized estimation equation models with a difference-in-differences analysis were used to estimate the effects of the reminder letters. RESULTS: Each group included 11,000 patients. Those who had received the reminder letter were less likely to receive duplicated medications in the subsequent 2 quarters (postintervention 1: odds ratio [OR]=0.95, 95% CI=0.87-1.03; postintervention_2: OR=0.99, 95% CI=0.90-1.08) and had fewer days of duplicated medications (postintervention 1: ß=-0.115, P =0.015; postintervention 2 (ß=-0.091, P =0.089) than those who had not received the reminder letter, showing marginal but significant differences. CONCLUSIONS: A one-off reminder letter nudge could mildly decrease the occurrence of duplicated medications. Multiple nudges or nudges incorporating behavioral science insights may be further considered to improve medication safety in health systems without gatekeeping.

BACKGROUND: Diabetes is one of the most prevalent chronic diseases with subsequent complications. The positive effects of diabetes pay-for-performance (P4P) programs on treatment outcomes have been reported. The program provides financial incentives based on physiological care indicators, but common mental disorder complications such as depression are not covered. METHODS: This study employed a natural experimental design to examine the spillover effects of diabetes P4P program on patients with nonincentivized depressive symptoms. The intervention group consisted of diabetes patients enrolled in the DM P4P program from 2010 to 2015. Unenrolled patients were selected by propensity score matching to form the comparison group. Difference-in-differences analyses were conducted to evaluate the effects of P4P programs. We employed generalized estimating equation (GEE) models, difference-in-differences analyses and difference-in-difference-in-differences analyses to evaluate the net effect of diabetes P4P programs. Changes in medical expenses (outpatient and total health care costs) over time were analysed for the treatment and comparison groups. RESULTS: The results showed that enrolled patients had a higher incidence of depressive symptoms than unenrolled patients. The outpatient and total care expenses of diabetes patients with depressive symptoms were lower in the intervention group than in the comparison group. Diabetes patients with depressive symptoms enrolled in the DM P4P program had lower expenses for depression-related care than those not enrolled in the program. CONCLUSIONS: The DM P4P program benefits diabetes patients by screening for depressive symptoms and lowering accompanying health care expenses. These positive spillover effects may be an important aspect of physical and mental health in patients with chronic disease enrolled in disease management programs while contributing to the control of health care expenses for chronic diseases.
RESUMEN
BACKGROUND: Longitudinal continuity between a patient and his/her primary care physician is an important aspect in measuring continuity of care (COC). The majority of previous studies employed questionnaire surveys to patients to measure the continual relationship between patients and their physicians. This study aimed to construct a provider duration continuity index (PDCI) by using longitudinal claims data and to examine its agreement with commonly used COC measures. Then, this study investigated the effects of the various types of COC measure on the likelihood of avoidable hospitalization while considering the level of comorbidity. METHODS: This study constructed a 4-year panel (from 2014 to 2017) of the nationwide health insurance claims data in Taiwan. In total, 328,044 randomly selected patients with 3 or more physician visits per year were analyzed. Two PDCIs were constructed to measure the duration of interaction between a patient and his/her physicians over time. The agreement between the PDCIs and three commonly used COC indicators, the Usual Provider of Care index, the Continuity of Care Index, and the Sequential Continuity Index, were examined. Generalized estimating equations were conducted to examine the association between COC and avoidable hospitalization by the level of comorbidity. RESULTS: The results showed that the correlations among the three commonly used COC indicators were high (γ = 0.787 ~ 0.958) and the correlation between the two longitudinal continuity measures was moderate (γ = 0.577 ~ 0.579), but the correlations between the commonly used COC indicators and the two PDCIs were low (γ = 0.001 ~ 0.257). All COC measures, both the PDCIs and the three commonly used COC indicators, showed independent protective effects on the likelihood of avoidable hospitalization in three comorbidity groups. CONCLUSION: The duration of interaction between patients and physicians is an independent domain in measuring COC and has a significant effect on health care outcomes.

Background: Home blood pressure telemonitoring (BPT) has been shown to improve blood pressure control. A community-based BPT program (the Health+ program) was launched in 2015 in an urban area around a medical center. Objectives: To examine the impact of the BPT program on the use of medical resources. Methods: We conducted a retrospective propensity-score (PS)-matched observational cohort study using the National Health Insurance Research Database (NHIRD) 2013-2016 in Taiwan. A total of 9,546 adults with a high risk of cardiovascular disease participated in the integrated BPT program, and 19,082 PS-matched controls were identified from the NHIRD. The primary and secondary outcome measures were changes in 1-year emergency department visit rate, hospitalization rate, duration of hospital stay, and healthcare costs. Results: The number of emergency department visits in the Health+ group significantly reduced (0.8 to 0.6 per year vs. 0.8 to 0.9 per year, p < 0.0001) along with a significant decrease in hospitalization rate (43.7% to 21.3% vs. 42.7% to 35.3%, p < 0.001). The duration of hospital stay was also lower in the Health+ group (4.3 to 3.3 days vs. 5.3 to 6.5 days, p < 0.0001). The annual healthcare costs decreased more in the Health+ group (USD 1642 to 1169 vs. 1466 to 1393 per year, p < 0.001), compared with the controls. Subgroup analysis of the Health+ group revealed that the improvements in outcomes were significantly greater among those who were younger and had fewer comorbidities, especially without diabetes or hypertension. Conclusions: A community-based integrated BPT program may improve patients' health outcomes and reduce healthcare costs.
RESUMEN
BACKGROUND: Little is known about hip fracture inpatient care in East Asia. This study examined the characteristics of patients, hospitals, and regions associated with delivery of hip fracture surgeries across Japan, Korea, and Taiwan. We also analyzed and compared how the resource use and a short-term outcome of the care in index hospitals varied according to factors in the respective health systems. METHODS: We developed comparable, nationwide, individual-level health insurance claims datasets linked with hospital- and regional-level statistics across the health systems using common protocols. Generalized linear multi-level analyses were conducted on length of stay (LOS) and total cost of index hospitalization as well as inpatient death. RESULTS: The majority of patients were female and aged 75 or older. The standardized LOS of the hospitalization for hip fracture surgery was 32.5 (S.D. = 18.7) days in Japan, 24.7 (S.D. = 12.4) days in Korea, and 7.1 (S.D. = 2.9) days in Taiwan. The total cost per admission also widely varied across the systems. Hospitals with a high volume of hip fracture surgeries had a lower LOS across all three systems, while other factors associated with LOS and total cost varied across countries. CONCLUSION: There were wide variations in resource use for hip fracture surgery in the index hospital within and across the three health systems with similar social health insurance schemes in East Asia. Further investigations into the large variations are necessary, along with efforts to overcome the methodological challenges of international comparisons of health system performance.

OBJECTIVE: This study aimed to evaluate the impact of the PharmaCloud program, a health information exchange program implemented in 2013, on medication duplication under a single-payer, universal health insurance program in Taiwan. STUDY DESIGN: This study employed a retrospective pre-post study design and used nationwide health insurance claim data from 2013 to 2015. A difference-in-difference analysis was conducted to evaluate the effects of inquiry rate on the probability of receiving duplicate medications and on the number of days of overlapping medication prescriptions after implementation of the PharmaCloud program. RESULTS: The study subjects included patients receiving medications in 7 categories: antihypertension drugs, 217,200; antihyperlipidemic drugs, 69,086; hypoglycemic agents, 103,962; antipsychotic drugs, 15,479; antidepressant drugs, 12,057; sedative and hypnotic drugs, 56,048; and antigout drugs, 18,250. Up to 2015, the overall PharmaCloud inquiry rate has increased to 55.36%-69.16%. Compared with subjects in 2013, subjects in 2014 and 2015 had a significantly lower likelihood of receiving duplicate medication in all 7 medication groups; for instance, for antihypertension drug users, the odds ratio (OR) was 0.91 with 95% confidence interval (CI)=0.90-0.92 in 2014, and the OR was 0.81 with 95% confidence interval=0.81-0.82 in 2015. However, a higher inquiry rate led to a lower likelihood of receiving duplicate medication and shorter periods of overlapping medications only in some of the medication groups. CONCLUSIONS: The health information exchange program has reduced medication duplication, yet the reduction was not entirely associated with record inquiries. The hospitals have responded to the challenge of medication duplication by enhancing internal prescription control via a prescription alert system, which may have contributed to the reduction in duplicate medications and is a positive, unintended consequence of the intervention.

AIMS: The direct cost of operations and health care expenditure for treating pelvic floor dysfunction are substantial. In this study, we evaluate the number of inpatient surgical procedures and direct expenditures for treating pelvic organ prolapse and urinary incontinence under the coverage of National Health Insurance (NHI) in Taiwan. METHODS: Thirteen years of population-based NHI inpatient claims were used in this study. The number of surgical procedures and the average direct cost of inpatient fees for treating pelvic floor dysfunction for each patient from 1999 to 2011 were calculated. The patients were stratified based on age into a younger than 65 years group and 65 years or older group for comparisons. RESULTS: The number of patients per year increased by 27%, increasing from 5278 patients in 1999 to 6706 patients in 2011. The total direct cost of inpatient (surgical and admission) fees for pelvic floor dysfunction increased by 57.2%, increasing from $6 674 968 USD in 1999 to $10 494 894 USD in 2011. However, while the expenditures for women 65 years or older increased by 102.2% from 1999 to 2011, there was only a 38.3% increase for those younger than 65 years when we stratified the patients by age. CONCLUSION: The increasing expenditures for inpatient surgery for pelvic floor dysfunction are mainly due to the escalating utilization of inpatient surgical procedures, especially those for pelvic organ prolapse in women aged 65 or older.

PURPOSE: Generic medications used for chronic diseases are beneficial in containing healthcare costs and improving drug accessibility. However, the effects of generic drugs in acute and severe illness remain controversial. This study aims to investigate treatment costs and outcomes of generic antibiotics prescribed for adults with a urinary tract infection in outpatient settings. METHODS: The data source was the Longitudinal Health Insurance Database of Taiwan. We included outpatients aged 20 years and above with a urinary tract infection who required one oral antibiotic for which brand-name and generic products were simultaneously available. Drug cost and overall healthcare expense of the index consultation, healthcare cost during a 42-day follow-up period, and treatment failure rates were the main dependent variables. Data were compared between brand-name and generic users from the entire cohort and a propensity score-matched samples. RESULTS: Results from the entire cohort and propensity score-matched samples were similar. Daily antibiotic cost was significantly lower among generic users than brand-name users. Significant lower total drug claims of the index consultation only existed in patients receiving the investigated antibiotics, while the drug price between brand-name and generic versions were relatively large (e.g., >50%). The overall healthcare cost of the index consultation, healthcare expenditure during a 42-day follow-up period, and treatment failure rates were similar between the two groups. CONCLUSIONS: Compared with those treated with brand-name antibiotics, outpatients who received generic antibiotics had equivalent treatment outcomes with lower drug costs. Generic antibiotics are effective and worthy of adoption among outpatients with simple infections indicating oral antibiotic treatment. Copyright © 2016 John Wiley & Sons, Ltd.

BACKGROUND: The effects of continuity of care on health care outcomes are well documented. However, little is known about the effect of continuity at the physician or the site level on the process of care for patients with multiple chronic conditions (MCCs). OBJECTIVE: The objective of this study was to examine the effects of physician continuity versus site continuity on duplicated medications received by patients with and without MCCs. RESEARCH DESIGN AND SUBJECTS: This study utilized a longitudinal design with an 8-year follow-up from 2004 to 2011 of patients aged 65 or older under a universal health insurance program in Taiwan (55,573 subjects and 389,011 subject-years). Generalized estimating equation models with propensity score method were conducted to assess the association between continuity and medication duplication. RESULTS: The rates of subjects receiving duplicated medications ranged from 40.38% to 43.50% with 1.45-1.62 duplicated medications during the study period. The findings revealed that better continuity, either at the physician level or the site level, was significantly associated with fewer duplicated medications. This study also indicated that the physician continuity had a stronger effect on medication duplication than did site continuity. Furthermore, the magnitude of the protective effect of continuity against duplicated medications increased when the patients had more chronic conditions [physician continuity: the marginal effect ranged from -10.7% to -52.9% (all P<0.001); site continuity: the marginal effect ranged from -0.4% (P=0.063) to -31.4% (P<0.001)]. CONCLUSION: Improving either physician continuity or site continuity may result in fewer duplicated medications, particularly for patients with MCCs.

BACKGROUND: Previous studies have shown that financial strategies are beneficial for improving the appropriate use of antibiotics within a limited period of time. Long-term effects have rarely been explored. METHODS: This study evaluated the changes in expenditure and prescription patterns of antibacterial agents under the global budget (GB) program and drug price adjustment of a National Health Insurance scheme. Two structural methods, that is, the Laspeyres method and Fisher's Ideal Index decomposition method, were used to illustrate the impacts of price, volume, and drug change. RESULTS: During the first 5 years of the GB program (ie, 2001-2006), the expenses of antibacterial agents increased by 54.1%, while the volume decreased by 11% to 21.3%. Therapeutic choice was the predominant cause of expense growth. In the second and third 5-year periods (ie, 2006-2011 and 2011-2016), the driving force of therapeutic choice gradually decreased. The antibacterial expense remained stable with a slight increase in prescription volume. Periodic price adjustment contributed steadily to cost containment, by 21.9% to 39.9%. CONCLUSIONS: The GB program led to a remarkable increase in antibacterial expenses mainly attributed to therapeutic choice, especially in the early stage. In contrast, periodic price adjustment, provided steady benefits to pharmaceutical budget control without a noticeable increase in drug volume.

BACKGROUND: The effects of continuity of care (COC) on health care outcomes are well established. However, the mechanism of this association is not fully understood. OBJECTIVE: The objective of this study was to examine the relationship between COC and medication adherence, as well as to investigate the mediating effect of medication adherence on the association between COC and health care outcomes, in patients with newly diagnosed type 2 diabetes. RESEARCH DESIGN AND SUBJECTS: This study utilized a longitudinal design and included a 7-year follow-up period from 2002 to 2009 under a universal health insurance program in Taiwan. Patients aged 18 years or older who were first diagnosed with type 2 diabetes in 2002 were included in the study. Random intercept models were conducted to assess the temporal relationship between COC, medication adherence, and health care outcomes. RESULTS: Patients with high or intermediate COC scores were more likely to be adherent to medications than those with low COC scores [odds ratio (OR), 3.37; 95% confidence interval (CI), 3.15-3.60 and OR, 1.84; 95% CI, 1.74-1.94, respectively]. In addition, the association between COC and health care outcomes was partly mediated by better medication adherence in patients with newly diagnosed type 2 diabetes. CONCLUSIONS: Improving the COC for patients with type 2 diabetes may result in higher medication adherence and better health care outcomes.

OBJECTIVE: To analyze the disparity in hospital care among people of various socio-economic status (SES) under a universal health insurance scheme. DESIGN: A survey questionnaire was mailed to discharged patients in October 2010. SETTING: This study included 183 large-scale hospitals in Taiwan. PARTICIPANTS: A total of 3015 patients/caregivers completed the questionnaires, which yielded a response rate of 58%. MAIN OUTCOME MEASURES: Three variables were included. The two access-to-care variables were admission route and accreditation level of the hospital in which the patient stayed. A structured questionnaire, the patient-reported hospital quality (PRHQ), was included to characterize patient's experience of hospital stay. RESULTS: Patients with lower education were less likely to be admitted to a hospital according to a planned schedule, or to choose an Medical Center Hospital. However, SES was not associated with the PRHQ scores. Furthermore, patients with unplanned admission were associated with lower PRHQ scores than those with planned admission to the hospital. CONCLUSIONS: Under the universal health insurance system in Taiwan, lower education is associated with unplanned admission to a hospital, which might result in poorer perceived quality of care. Reducing unplanned admission is a challenge for health authorities in the future.

Numerous studies have investigated the relationship between continuity of care (COC) and patient satisfaction. However, COC and patient satisfaction were measured simultaneously; therefore, the direction of causality remains understudied. This study examined the effect of COC on the patient satisfaction of elderly individuals using an instrumental variable (IV) approach. Nationwide survey data acquired using a face-to-face interview were used to measure the patient-reported COC experiences of 1,715 participants. We applied an ordered logit model controlled for observed patient characteristics and a two-stage residual inclusion (2SRI) ordered logit model that accounted for unobserved confounding factors. Patient-perceived COC importance was used as an IV for patient-reported COC. The ordered logit models indicated that patients with high or intermediate patient-reported COC scores were more likely to perceive more patient satisfaction than those with low COC scores. Using the patient-perceived COC importance as an IV, we examined a strong significant association between the level of patient-reported COC and patient satisfaction. It is necessary to adjust for unobserved confounders to obtain more accurate estimates of the relationship between patient-reported COC and patient satisfaction. However, the results and policy implications of this study should be cautiously interpreted because the possibility of other bias could not be ruled out. These findings support policies aimed at improving patient-reported COC among older adults.

OBJECTIVES: This study examined the relationship between claims-based and patient-reported continuity of care (COC) measures and investigated the effects of the 2 types of COC measures on subjective and objective health care outcomes. STUDY DESIGN: A prospective, cross-sectional, correlational survey design was used. A nationwide face-to-face interview survey of community-dwelling older adults was conducted, and the survey participants' health claims records were retrieved and linked under the universal health insurance system of Taiwan in 2018. METHODS: Health care outcomes were measured subjectively (patient satisfaction and perceived lack of coordination) and objectively (likelihood of hospital admissions and emergency department [ED] visits). COC was measured using claims-based and multidimensional patient-reported COC. Ordered logit and logit models were used to examine the relationship between the 2 types of COC measures, and health care outcomes were measured subjectively and objectively. Average marginal effects with bootstrapped SEs were computed for health care outcomes. RESULTS: This study demonstrated that the correlations of claims-based and patient-reported COC measures were quite low and mainly insignificant. A higher claims-based COC was significantly associated with a lower likelihood of hospital admissions, ED visits, and perceived lack of coordination. No significant relationship was identified between claims-based COC and patient satisfaction. Participants reporting higher COC had better patient satisfaction and less perceived lack of coordination. However, no relationship was identified between patient-reported COC and the likelihood of hospital admissions and ED visits. CONCLUSIONS: The correlation between claims-based and patient-reported COC measures is low, and claims-based and patient-reported COC measures are associated with different subjective and objective health care outcomes. We suggest that claims-based COC indicators representing the pattern of physician visits might be considered a unique dimension of COC.

BACKGROUND: Several studies have examined the intended effects of pay-for-performance (P4P) programs, yet little is known about the unintended spillover effects of such programs on intermediate clinical outcomes. This study examines the long-term spillover effects of a P4P program for diabetes care. METHODS: This study uses a nationwide population-based natural experimental design with a 3-year follow-up period under Taiwan's universal coverage healthcare system. The intervention group consisted of 7688 patients who enrolled in the P4P program for diabetes care in 2017 and continuously participated in the program for three years. The comparison group was selected by propensity score matching (PSM) from patients seen by the same group of physicians. Each patient had four records: one pertaining to one year before the index date of the P4P program and the other three pertaining to follow-ups spanning over the next three years. Generalized estimating equations (GEEs) with difference-in-differences (DID) estimations were used to consider the correlation between repeated observations for the same patients and patients within the same matched pairs. RESULTS: Patients enrolled in the P4P program showed improvements in incentivized intermediate clinical outcomes that persisted over three years, including proper control of glycated hemoglobin (HbA1c) and low-density lipoprotein cholesterol (LDL-C). We found a slight positive spillover effect of the P4P program on the control of non-incentivized triglyceride [TG]). However, we found no such effects on the non-incentivized high-density lipoprotein cholesterol (HDL-C) control. CONCLUSION: The P4P program has achieved its primary goal of improving the incentivized intermediate clinical outcomes. The commonality in production among a set of activities is crucial for generating the spillover effects of an incentive program.

Introduction: Both care continuity and coordination are considered essential elements of health care system. However, little is known about the relationship between care continuity and coordination. This study aimed to differentiate the concepts of care continuity and coordination by developing and testing the reliability and validity of the Combined Outpatient Care Continuity and Coordination Assessment (COCCCA) questionnaire under the universal coverage health care system in Taiwan from a patient perspective. Methods: Face-to-face interviews were conducted nationwide with community-dwelling older adults selected via stratified multistage systematic sampling with probability-proportional-to-size process. A total of 2,144 subjects completed the questionnaire, with a response rate of 44.67%. Results: The 16 items of the COCCCA questionnaire were identified via item analysis and principal component analysis (PCA). The PCA generated five dimensions: three continuity-oriented (interpersonal, information sharing and longitudinal between patients and physicians) and two coordination-oriented (information exchange and communication/cooperation among multiple physicians). The second-order confirmatory factor analysis supported the factor structure and indicated that distinct constructs of care continuity and coordination can be identified. Conclusion: The COCCCA instrument can differentiate the concepts of care continuity and care coordination and has been demonstrated to be valid and reliable in outpatient care settings from a patient perspective.
RESUMEN
BACKGROUND: Although there have been studies that compared outcomes of patients with acute myocardial infarction (AMI) across countries, little focus has been placed on institutional variance of outcomes. The aim of the present study was to compare institutional variance in mortality following percutaneous coronary intervention (PCI) for AMI and factors explaining this variance across different health systems. METHODS: Data on inpatients who underwent PCI for AMI in 2016 were obtained from the National Health Insurance Data Sharing Service in Korea, the Diagnosis Procedure Combination (DPC) Study Group Database in Japan, and the National Health Insurance Research Database (NHIRD) in Taiwan. Multilevel analyses with inpatient mortality as the outcome and the hierarchical structure of patients nested within hospitals were conducted, adjusting for common patient-level and hospital-level variables. We compared the intraclass correlation coefficient (ICC) and the proportion of variance explained by hospital-level characteristics across the three health systems. RESULTS: There were 17 351 patients from 160 Korean hospitals, 29 804 patients from 660 Japanese hospitals, and 10 863 patients from 104 Taiwanese hospitals included in the analysis. Inpatient mortality rates were 6.3%, 7.3%, and 6.0% in Korea, Japan, and Taiwan, respectively. After adjusting for patient and hospital characteristics, Taiwan had the lowest variation in mortality (ICC, 1.8%), followed by Korea (2.2%) and then Japan (4.5%). The measured hospital characteristics explained 38%, 19%, and 9% of the institutional variance in Korea, Taiwan, and Japan, respectively. CONCLUSION: Korea, Japan, and Taiwan had similarly uniform outcomes across hospitals for patients undergoing PCI for AMI. However, Japan had a relatively large institutional variance in mortality and a lower proportion of variation explainable by hospital characteristics, compared with Korea and Taiwan.

BACKGROUND: Better continuity of care (COC) is associated with improved health care outcomes, such as decreased hospitalization and emergency department visit. However, little is known about the effect of COC on potentially inappropriate medication. OBJECTIVES: This study aimed to investigate the association between COC and the likelihood of receiving inappropriate medication, and to examine the existence of a mediating effect of inappropriate medication on the relationship between COC and health care outcomes and expenses. METHODS: A longitudinal analysis was conducted using claim data from 2004 to 2009 under universal health insurance in Taiwan. Participants aged 65 years and older were categorized into 3 equal tertiles by the distribution of COC scores. This study used a propensity score matching approach to assign subjects to 1 of 3 COC groups to increase the comparability among groups. Generalized estimating equations were used to examine the association between COC, potentially inappropriate medication, and health care outcomes and expenses. RESULTS: The results revealed that patients with the best COC were less likely to receive drugs that should be avoided [odd ratios (OR), 0.44; 95% confidence interval (CI), 0.43-0.45) or duplicated medication (OR, 0.22; 95% CI, 0.22-0.23) than those with the worst COC. The findings also indicated that potentially inappropriate medication was a partial mediator in the association between COC and health care outcomes and expenses. CONCLUSION: Better COC is associated with fewer negative health care outcomes and lower expenses, partially through the reduction of potentially inappropriate medication. Improving COC deserves more attention in future health care reforms.

BACKGROUND: Numerous studies have examined the impacts of pay-for-performance programs, yet little is known about their long-term effects on health care expenses. OBJECTIVES: This study aimed to examine the long-term effects of a pay-for-performance program for diabetes care on health care utilization and expenses. METHODS: This study represents a nationwide population-based natural experiment with a 4-year follow-up period under a compulsory universal health insurance program in Taiwan. The intervention groups consisted of 20,934 patients enrolled in the program in 2005, and 9694 patients continuously participated in the program for 4 years. Two comparison groups were selected by propensity score matching from patients seen by the same group of physicians. Generalized estimating equations were used to estimate differences-in-differences models to examine the effects of the pay-for-performance program. RESULTS: Patients enrolled in the pay-for-performance program underwent significantly more diabetes specific examinations and tests after enrollment; the differences between the intervention and comparison groups declined gradually over time but remained significant. Patients in the intervention groups had a significantly higher number of diabetes-related physician visits in only the first year after enrollment and had fewer diabetes-related hospitalizations in the follow-up period. Concerning overall health care expenses, patients in the intervention groups spent more than the comparison group in the first year; however, the continual enrollees spent significantly less than their counterparts in the subsequent years. CONCLUSIONS: The program seemed to achieve its primary goal in improving health care and providing long-term cost benefits.

OBJECTIVES: This study aimed to examine the associations between adoption of an advanced medication alert system and decreases in hospital-based outpatient duplicated medication rates in Taiwan. METHODS: The unit of analysis was the hospital. We merged the hospital medication alert system adoption survey data and Taiwan National Health Insurance outpatient claims data. The observation time was 1998 to 2011, divided into 5 periods (T1-T5). The analysis included 216 hospitals, and outcome variable was hospital-based outpatient duplicated medication rates. The system adoption time frame, hospital accreditation level, and number of drugs per prescription were defined as predicted variables. A generalized estimating equation regression model was used. RESULTS: Adoption of the advanced medication alert system gradually increased, such that 100% of medical centers and 84% of regional hospitals, but less than 50% of district hospitals, had systems by T5. The hospital-based outpatient duplicated medication rate continually decreased, from 29.8% to 11.2%. The generalized estimating equation model showed rates of duplicated medications of b = -8.44 at T2 and b = -17.88 at T5 (P < 0.001) compared with T1. Medical centers and regional hospitals demonstrated much lower duplication rates (b = -13.71, b = -6.82; P < 0.001) compared with district hospitals. Hospitals with more medications per prescription had higher duplication rates than did hospitals with fewer items. CONCLUSIONS: Hospitals accredited at higher levels tended to have advanced medication alert systems. Hospitals that implemented advanced systems decreased hospital-based outpatient duplicated medications, avoiding a potential risk due to inappropriate medication use.
