RESUMO
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.

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.
RESUMO
(1) Background: The coronavirus disease 2019 (COVID-19) pandemic had overwhelming impacts on medical services. During its initial surge, Taiwan was unique in maintaining its medical services without imposing travel restrictions, which provided an ideal environment in which to test if the fear of becoming infected with COVID-19 interfered with health-seeking behavior (HSB). We tested this hypothesis among adults with acute complicated appendicitis (ACA). (2) Methods: Adults with acute appendicitis were enrolled between 1 January and 30 June 2020 (COVID-19 period). The first two quarters of the preceding 3 years were defined as a historical control group. Outcome measures included the rate of ACA and the number of hospital stays. (3) Results: The COVID-19 era included 145 patients with acute appendicitis. Compared to the historical control (320 patients), the COVID-19 era was significantly associated with a higher length of symptom duration until presentation to the emergency room within >48 h (17.2% vs. 9.1%, p = 0.011), a higher incidence of ACA (29.7% vs. 19.4%, p = 0.014), and a longer length of hospital stays (5.0 days vs. 4.0 days, p = 0.043). The adjusted models showed that the COVID-19 period had a significant relationship with a higher rate of ACA (odds ratio (OR) = 1.87; 95% confidence interval (CI): 1.23-2.52; p = 0.008) and longer length of hospital stays (OR= 2.10; 95% CI: 0.92 to 3.31; p < 0.001). (4) Conclusions: The fear of COVID-19 may prohibit patients from seeking medical help, worsening their clinical outcomes. The surgical community should take action to provide scientific information to relive mental stress.

Medical masks have become necessary of late because of the COVID-19 outbreak; however, they tend to attenuate the energy of speech signals and affect speech quality. Therefore, this study proposes an optical-based microphone approach to obtain speech signals from speakers' medical masks. Experimental results showed that the optical-based microphone approach achieved better performance (85.61%) than the two baseline approaches, namely, omnidirectional (24.17%) and directional microphones (31.65%), in the case of long-distance speech and background noise. The results suggest that the optical-based microphone method is a promising approach for acquiring speech from a medical mask.

INTRODUCTION: In very low birth weight (VLBW) infants, hypothermia immediately following birth is common even in countries rich in medical resources. The purpose of this study is to design a standard prevention bundle that decreases the rate of hypothermia among infants after birth and to investigate efficacy of the bundle and short-term outcomes for VLBW infants. METHODS: This quality improvement project was conducted from February 2017 to July 2018 on all VLBW preterm infants admitted at a single referral level III neonatal intensive care unit. The infants were classified into the pre-intervention (February to September 2017) and post-intervention (October 2017 to July 2018) groups according to the time periods when they were recruited. During the pre-intervention period, we analyzed the primary causes of hypothermia, developed solutions corresponding to each cause, integrated all solutions into a prevention bundle, and applied the bundle during the post-intervention period. Afterwards, the incidence of neonatal hypothermia and short-term outcomes, such as intraventricular hemorrhage (IVH), acidosis, and shock requiring inotropic agents, in each group were compared. RESULTS: A total of 95 VLBW infants were enrolled in the study, including 37 pre-intervention, and 58 post-intervention cases. The incidence of hypothermia in preterm infants decreased significantly upon the implementation of our prevention bundle, both in the delivery room (from 45.9% to 8.6%) and on admission (59.5% to 15.5%). In addition, the short-term outcomes of VLBW infants improved significantly, especially with the decreased incidence of IVH (from 21.6% to 5.2%, P = 0.015). CONCLUSIONS: Our standardized prevention bundle for preventing hypothermia in VLBW infants is effective and decreased the IVH rate in VLBW infants. We strongly believe that this prevention bundle is a simple, low-cost, replicable, and effective tool that hospitals can adopt to improve VLBW infant outcomes.

Background: Methylxanthines (caffeine; aminophylline/theophylline) are commonly used for apnea of prematurity (AOP) treatment. We aimed to compare the efficacy and adverse effects of caffeine and aminophylline/theophylline. Methods: A retrospective case-control gestational age-matched study investigates patients born between January 2017 and December 2018, 23-35 weeks gestation with birth weights >500 g treating AOP with caffeine or aminophylline/theophylline. Results: There were 144 cases (48 in caffeine group and 96 in aminophylline/theophylline group). The median treatment durations were 11 and 17 days in caffeine and aminophylline/theophyllinegroup (p = 0.002). When tachycardia is defined as heart rate ≥160 bpm, the rates were 8.3 and 34.4% in caffeine and control group (p = 0.001). When tachycardia is defined as 10 bpm over baseline heart rate, the rates were 41.7 and 63.5% in caffeine and aminophylline/theophylline group (p = 0.01). Stratified by gestational age and sex, significant reductions in tachycardia rates with caffeine than with theophylline were limited to male infants and infants born at <30 weeks gestation. Conclusions: For apnea treatment, caffeine has greater efficacy and fewer tachycardia than aminophylline/theophylline, especially in male infants and infants born at <30 weeks gestation.
RESUMO
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.

Lung cancer is one of the leading causes of cancer-related death worldwide. The most common type of lung cancer is non-small cell lung cancer (NSCLC). When NSCLC is detected, patients are typically already in a metastatic stage. Metastasized cancer is a major obstacle of effective treatment and understanding the mechanisms underlying metastasis is critical to treat cancer. Herein, we selected an invasive subpopulation from the human lung cancer cell line A549 using the transwell system and named it as A549-I5. Invasive and migratory activities of this cell line were analysed using wound healing, invasion, and migration assays. In addition, epithelial-mesenchymal transition (EMT) markers, such as Snail 1, Twist, Vimentin, N-cadherin and E-cadherin, were assessed through immunoblotting. In comparison to A549 cells, the invasive A549-I5 lung cancer cells had enhanced invasiveness, motility and EMT marker expression. Proteomic analysis identified 83 significantly differentially expressed proteins in A549-I5 cells. These identified proteins were classified according to their cellular functions and most were involved in cytoskeleton, redox regulation, protein degradation and protein folding. In summary, our results provide potential diagnostic markers and therapeutic candidates for the treatment of NSCLC metastasis. SIGNIFICANCE OF THE STUDY: When NSCLC is detected, most patients are already in a metastatic stage. Herein, we selected an invasive subpopulation from a human lung cancer cell line which had increased EMT markers as well as high wound healing, invasion and migration abilities. Proteomic analysis identified numerous proteins associated with functions in cytoskeleton, redox regulation, protein degradation and protein folding that were differentially expressed in these cells. These results may provide potential diagnostic markers and therapeutic candidates for the treatment of NSCLC metastasis.

Delphinidin is a flavonoid belonging to dietary anthocyanidin family that has been reported to possess diverse anti-tumoral activities. However, the effects of delphinidin on colorectal cancer (CRC) cells and the underlying mechanisms are not fully understood. Thus, we aimed to investigate the anti-cancer activity of delphinidin in CRC cells and the underlying molecular mechanisms. The effects of delphinidin on the viability, metastatic characteristics, signaling, and microRNA (miR) profile of human CRC cell lines used were analyzed. In vivo metastasis was also evaluated using xenograft animal models. Our findings showed that delphinidin (<100 µM) inhibited the colony formation of DLD-1, SW480, and SW620 cells, but non-significantly affected cell viability. Delphinidin also suppressed the migratory ability and invasiveness of the tested CRC cell lines, downregulated integrin αV/ß3 expression, inhibited focal adhesion kinase (FAK)/Src/paxillin signaling, and interfered with cytoskeletal construction. Analysis of the miR expression profile revealed a number of miRs, particularly miR-204-3p, that were significantly upregulated and downregulated by delphinidin. Abolishing the expression of one upregulated miR, miR-204-3p, with an antagomir restored delphinidin-mediated inhibition of cell migration and invasiveness in DLD-1 cells as well as the αV/ß3-integrin/FAK/Src axis. Delphinidin also inhibited the lung metastasis of DLD-1 cells in the xenograft animal model. Collectively, these results indicate that the migration and invasion of CRC cells are inhibited by delphinidin, and the mechanism may involve the upregulation of miR-204-3p and consequent suppression of the αV/ß3-integrin/FAK axis. These findings suggest that delphinidin exerts anti-metastatic effects in CRC cells by inhibiting integrin/FAK signaling and indicate that miR-204-3p may play an important role in CRC metastasis.

After acute hip surgery, the 1-year mortality rate is high. Therefore, this study evaluated the risk factors for 1-year mortality. The purposes of this study was first to examine the effect of integrated care on 1-year mortality in surgical patients and secondly to explore magnitude of comorbidity and complication on mortality.This retrospective cohort study included 313 patients received surgery for hip fragility fracture. Patients with multiple fractures or combined trauma were excluded. The patients were grouping into integrated (nâ=â106) and non-integrated care group (nâ=â207) models. Univariate and multiple Cox regression were used to examine effect of care model, comorbidity, and complication event.One-year mortality in integrated and non-integrated patients was 4.7% and 14.0% respectively. After adjustments, patients in non-integrated care, have 2.89 times (95% confidence interval [CI] 1.07-7.81) likely to die 1-year after discharged.Patients had elevated comorbidity or postoperative complications contributed to the mortality. Our study found the effect of patients treated by integrated care models, compared with usual model, significantly reduced 1-year mortality rate. Appropriated treatment of comorbidities during hospitalization and after discharge is critical to post-surgical survival. The findings imply that the co-care for hip fracture of hip surgical patients with orthogeriatricians is strongly recommended, particularly for those with >3 comorbidities.

Proteasome primarily degrades the unneeded or damaged proteins by proteolysis. Disruption of the brain barrier and its resulting meningoencephalitis caused by Angiostrongylus cantonensis are important pathological events in non-permissive hosts. In this study, the results showed upregulated proteasome during A. cantonensis infection. Occludin degradation and matrix metalloproteinase-9 (MMP-9) activity were significantly increased in infected mice than in uninfected mice. Moreover, confocal immunoflourescence microscopy showed that occludin was co-localized with MMP-9. The infected-mice were treated with proteasomal activity inhibitor MG132 by 1.5 and 3.0 mg/kg/day, which resulted in significantly reduced protein levels of phosphorylated IκBα (P<0.05) compared with the untreated control. The phosphorylated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) showed similar result. In addition, MMP-9 activity and occludin degradation were reduced because of MG132 treatment. These results suggested that the proteasome in A. cantonensis infection degraded phosphorylated IκBα, modulated phosphorylated NF-κB, and then regulated the activation of MMP-9 and occludin degradation. Proteasome alterations were presented in eosinophilic meningitis of BALB/c mice and may contribute to the pathophysiology of eosinophilic meningitis by increasing occludin degradation. This molecule would serve as pivotal regulator in A. cantonensis-induced eosinophilic meningoencephalitis.

AIMS: The most frequent cancers among women worldwide. The mortality of cervical cancer has declined significantly primarily due to the widespread use of Pap smear tests as a screening test and therapeutic vaccination. However, cervical cancer still remains a severe disease among the female population, as the prognosis of metastatic cervical cancer is very poor. KEY METHODS: In this study, we performed 2D-DIGE and MALDI-TOF/TOF MS to analyze differentially expressed proteins between HeLa and invasive HeLa-I5 cells.. KEY FINDINGS: According to our proteomics data, 68 differentially expressed proteins between the HeLa and HeLa-I5 cells were identified. One of these differentially expressed proteins, Progesterone receptor membrane component 1 (PGRMC1), was selected as a candidate for further studies. To correlate the role of PGRMC1 with cellular migration and cancer progression, small interfering RNA (siRNA) was used to knockdown the expression of PGRMC1. Similar function of PGRMC1 was also observed in two other cervical cancer lines, CaSki and ME-180. SIGNIFICANCE: PGRMC1 plays an essential role in regulating cancer progression and metastasis of cervical cancer cells, thus serving as a potential therapeutic target for cervical cancer.

BACKGROUND: Medicine is no longer limited to the treatment of diseases-the use of plastic surgical techniques as a commodity to improve the appearance of healthy people has become a trend, and plastic surgeons who invest in the market of cosmetic medicine have quickly gained considerable benefits. Will the transformation of the role of plastic surgeons from aesthetic restoration to commercial embellishment damage the creation and maintenance of their sense of professionalism? OBJECTIVES: The purpose of this study was to determine, by utilizing Q methodology, which aspects of professionalism plastic surgeons value. METHODS: Q methodology is a mixed research method employed to study subjectivity through factor analysis. This study analyzes a rank-ordering of participants' level of agreement with a set of subjective statements related to a given topic. Q statements were developed on the basis of a literature review, expert panels, and medical organizations' codes of conduct. After face and construct validity checks, as well as a pilot test, we interviewed 31 attending plastic surgeons. Data were collected from April to May 2017. RESULTS: This study concluded that the main types of medical professionalism held by the respondents can be represented in 4 factors: (1) mastery of clinical skills, (2) leadership and management, (3) knowledge sharing, and (4) multifaceted. CONCLUSIONS: Respondents in this study highly emphasized surgical skill and sought to maintain good relationships with their patients based on their settings. Although they were reluctant to place community service as a top priority, our respondents tended to emphasize the healer aspect over commercialization.

BACKGROUND: Three operative techniques have been used for colorectal cancer (CRC) resection: Conventional laparotomy (CL) and the mini-invasive techniques (MITs)- laparoscopic-assisted surgery (LAS) and mini-laparotomy (ML). The aim of the study was to compare the short- and long-term outcomes of patients undergoing the three surgical approaches for Stage I-III CRC resection. PATIENTS AND METHODS: This study enrolled 688 patients with Stage I-III CRC undergoing curative resection. The primary endpoints were perioperative quality and outcomes. The secondary endpoints were oncological outcomes including disease-free survival (DFS), overall survival (OS) and local recurrence (LR). RESULTS: Patients undergoing LAS had significantly less blood loss (P < 0.001), earlier first flatus (P = 0.002) and earlier resumption of normal diet (P = 0.025). Although post-operative complication rates were remarkably higher in patients undergoing CL than in those undergoing MITs (P = 0.002), no difference was observed in the post-operative mortality rate (P = 0.099) or 60-day re-intervention rate (P = 0.062). The quality of operation as assessed by the number of lymph nodes harvested and rates of R0 resection did not differ among the groups (all P > 0.05). During a median follow-up of 5.42 years, no significant difference was observed among the treatment groups in the rates of 3-year late morbidity, 3-year LR, 5-year LR, 5-year OS or 5-year DFS (all P > 0.05). CONCLUSIONS: Patients undergoing CL had higher post-operative morbidities. Moreover, the study findings confirm the favourable short-term and comparable long-term outcomes of LAS and ML for curative CRC resection. Therefore, both MITs may be feasible and safe alternatives to CL for Stage I-III CRC resection.
RESUMO
OBJECTIVE: There has been a growing recognition that obstructive sleep apnea (OSA) could increase the propensity for type 2 diabetes the metabolic syndrome. However, studies concerning about the impact of non-apnea sleep disorders (NSD) on diabetes control and metabolic outcomes are relatively scarce. Our aim is to investigate the impact of non-apnea sleep disorders (NSD) on diabetic control and associated metabolic outcomes in patients with type 2 diabetes. METHODS: The data were obtained from two nationwide population-based databases for a period 2007 to 2012. A total 66,992 patients with type 2 diabetes were enrolled and divided into two cohorts based on comorbidity with or without a NSD diagnosis, and were followed up four years. The primary outcomes were to compare rate of change in HbA1c and associated metabolic outcomes during follow-up visits between patients with or without NSD. The secondary outcome is to examine whether NSD were associated with poor glycemic control of the last clinical records while controlling for the baseline HbA1c value. RESULTS: Of the 66,992 patients with type 2 diabetes, 14.82% had comorbidity with a NSD. HbA1C decreases were significantly lower by 0.04% in the NSD group (Pâ¯<â¯0.05), and triglyceride (TG) decreases remained significantly lower by 2.53% in the NSD group (Pâ¯<â¯0.05). Furthermore, patients in the NSD group had an 8% higher risk of poor glycemic control (HbA1C >9) (ORâ¯=â¯1.08; 95%CI, 1.01-1.16). CONCLUSION: Our findings indicated patients with type 2 diabetes comorbid with NSD had a slower improvement in HbA1c compared with the comparison cohort. It may because there may exist potential floor effect given those with NSD having significantly lower HbA1c values at baseline. On the other hand, the poor diabetic control among those with NSD may be also affected by other confounders such as medical treatment or interventions. Nevertheless, given the rapidly increasing prevalence of metabolic diseases and subsequent complications, the results may highlight the importance of sleep in the clinical management of type 2 diabetes.

Objectives To assess the impact of minor, major and individual complications on prolonged length of hospital stay in patients with colorectal cancer (CRC) after surgery using multivariate models. Methods This was a retrospective review of data from patients who underwent surgery for stage I-III CRC at two medical centres in southern Taiwan between 2005-2010. Information was derived from four databases. Multivariate logistic regression methods were used to assess the impact of complications on prolonged length of stay (PLOS) and prolonged postoperative length of stay (PPOLOS). Results Of 1658 study patients, 251 (15.1%) experienced minor or major postsurgical complications during hospitalizations. Minor and major complications were significantly associated with PLOS (minor, odds ratio [OR] 3.59; major, OR 8.82) and with PPOLOS (minor, OR 5.55; major, OR 10.00). Intestinal obstruction, anastomosis leakage, abdominal abscess and bleeding produced the greatest impact. Conclusions Minor and major complications were stronger predictors of prolonged hospital stay than preoperative demographic and disease parameters. Compared with the PLOS model, the PPOLOS model better predicted risk of prolonged hospital stay. Optimal surgical and medical care have major roles in surgical CRC patients.

OBJECTIVE: Few studies address quality of care in pay-for-performance (P4P) programs from the perspective of patients' perceptions. This study aimed to examine and compare the patient assessment of diabetes chronic care as perceived by diabetic patients enrolled and not enrolled in a P4P program from the patients' self-reported perspectives. DESIGN: A cross-sectional study with case and comparison group design. SETTING: A large-scale survey was conducted from February to November 2013 in 18 healthcare institutions in Taiwan. PARTICIPANTS: A total of 1458 P4P (n = 1037) and non-P4P (n = 421) diabetic patients participated in this large survey. The Chinese version of the Patient Assessment of Chronic Illness Care (PACIC) instrument was used and patients' clinical outcome data (e.g. HbA1c, LDL) were collected. INTERVENTION: None. MAIN OUTCOME MEASURES: Five subscales from the PACIC were measured, including patient activation, delivery system design/system support, goal setting/tailoring, problem solving/contextual and follow-up/coordination. Patient clinical outcomes were also measured. Multiple linear regression and logistic regression models were used and controlled for patient demographic and health institution characteristics statistically. RESULTS: After adjusting for covariates, P4P patients had higher overall scores on the PACIC and five subscales than non-P4P patients. P4P patients also had better clinical processes of care (e.g. HbA1c test) and intermediate outcomes. CONCLUSIONS: Patients who participated in the program likely received better patient-centered care given the original Chronic Care Model. Better perceptions of diabetic care assessment also better clinical outcomes. The PACIC instrument can be used for the patient assessment of chronic care in a P4P program.

Melanin uncontrollable accumulation is a serious social problem to not only women, but also men, and causes pigment over-expression disorders such as freckles, melasma or pigmented acne scars. The synergism is used widely in medication, and the effectiveness makes the drug applications more valuable. Within this experiment, three well-known compounds were chosen: kojic acid, 1-phenyl-2-thiourea (PTU) and arbutin, and they were combined individually with our substance linderanolide B, which is purified from Cinnamomum subavenium. Hence, deciphering the synergistic action of possible whitening agents was the goal of this study. The tyrosinase activity, melanin content, and the combination index (CI) values were observed in B16F10 cells, in addition, the consequences were detected by isobologram analysis. We discovered that certain melanin inhibitors showed synergistic properties when they were combined together to suppress tyrosinase activities. As a result, linderanolide B has a potential synergy on tyrosinase inhibition, and it can be used widely in cosmetic and medication industries.

Pay for performance (P4P) has been used as a strategy to improve quality for patients with chronic illness. Little was known whether care provided to individuals with multiple chronic conditions in a P4P program were cost-effective. This study investigated cost effectiveness of a diabetes P4P program for caring patients with diabetes alone (DM alone) and diabetes with comorbid hypertension and hyperlipidemia (DMHH) from a single payer perspective in Taiwan. Analyzing data using population-based longitudinal databases, we compared costs and effectiveness between P4P and non-P4P diabetes patient groups in two cohorts. Propensity score matching (PSM) was used to match comparable control groups for intervention groups. Outcomes included life-years, quality-adjusted life-years (QALYs), program intervention costs, cost-savings and incremental cost-effectiveness ratios (ICERs). QALYs for P4P patients and non-P4P patients were 2.80 and 2.71 for the DM alone cohort and 2.74 and 2.66 for the DMHH patient cohort. The average incremental intervention costs per QALYs was TWD$167,251 in the DM alone cohort and TWD$145,474 in the DMHH cohort. The average incremental all-cause medical costs saved by the P4P program per QALYs were TWD$434,815 in DM alone cohort and TWD$506,199 in the DMHH cohort. The findings indicated that the P4P program for both cohorts were cost-effective and the resulting return on investment (ROI) was 2.60:1 in the DM alone cohort and 3.48:1 in the DMHH cohort. We conclude that the diabetes P4P program in both cohorts enabled the long-term cost-effective use of resources and cost-savings, especially for patients with multiple comorbid conditions.

OBJECTIVE: The purpose of this study was to explore the relationship between accessibility of healthcare facilities and medical care utilization among the middle-aged and elderly population in Taiwan. DESIGN: Cross-sectional study from 2007 Taiwan Longitudinal Study on Ageing (TLSA) survey. SETTING: Community-based study. PARTICIPANTS: A total of 4249 middle-aged and elderly subjects were recruited. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Outpatient visits within 1 month, and hospitalization, emergency visits as well as to shop in pharmacy stores within 1 year, respectively. RESULTS: Adjusting for important confounding variables, the middle-aged and elderly with National Health Insurance (NHI) and commercial insurance compared with those with NHI alone tended to have outpatient visits. The middle-aged and elderly with longer time to access healthcare facilities were less likely to shop in pharmacy stores compared with those with <30 min. The middle-aged and elderly who perceived inconvenient to access health care tended to shop in pharmacy stores compared with those with perceived convenience. CONCLUSIONS: Our study of Taiwan's experience could provide a valuable lesson for countries that are planning to launch universal health insurance system, locate budgets in health care and transportation. The middle-aged and elderly who were facing more challenges in accessing health care, no matter in perceived accessibility or real time to access health care, had less outpatient visits and more drug stores shopping. Strategic policies are needed to improve accessibility in increasing patients' perception on access and escalating convenience of transportation system for improving accessibility.
