RESUMO
The risks of tracheitis have been widely studied, but no investigation has yet to assess the impact of air pollutants on tracheitis hospital admissions. This research explores the relationship between Asia dust storm (ADS) and tracheitis hospital admissions, by using a Poisson time-series model on the 2000-2012 National Health Insurance Research Database (NHIRB) from Taiwan and linking air pollutants and temperature data. From a total of 126,013 tracheitis hospital admissions, the average number of daily tracheitis hospital admissions is 26.53 and increases 10% notably one day after ADS. The empirical result shows that ADS does significantly affect tracheitis hospital admissions 3 and 5 days after an event for the overall sample and 2-4 days after it for females. For the age group <45, the number significantly increases 3-4 days after ADS, revealing that ADS has a prolonged effect on tracheitis hospital admissions.

PURPOSE: Few studies have explored population-based incidence rates of microtia using nationwide data. The aim of this study was to analyze the 10-year secular trends in the incidence of microtia and/or anotia in Taiwan from 2008 to 2017 using nationwide population-based data. METHODS: Patient data were retrieved from Taiwan's National Health Insurance Dataset, after identifying 1152 children aged ≤ 1 year with a first-time diagnosis of microtia or anotia between January 2008 and December 2017. The annual microtia-anotia incidence rate was the sum of new microtia-anotia cases in a year divided by total infant population in the year. Furthermore, we used the annual percent change (APC) to study the secular trend in microtia-anotia incidence rate. RESULTS: The annual incidence rate of microtia-anotia averaged across the 10-year period was 57.7 per 100,000 infants (standard deviation = 8.6). The annual incidence rates of microtia and anotia were 53.3 and 4.4 per 100,000 infants, respectively, during this period. Furthermore, female infants had a higher incidence than males (63.3 vs. 52.4 per 100,000). The incidence of microtia-anotia gradually decreased between 2008 and 2017 with an APC of - 5.64% (95% CI - 9.31 ~ - 1.18%, p = 0.004). Since 2011, females had a significantly higher annual incidence rate of microtia-anotia than males. CONCLUSIONS: The incidence of microtia-anotia was 57.7 per 100,000 infants in Taiwan, which declined during the study period 2008-2017. The female-to-male incidence ratio was 1.21:1.

OBJECTIVE: This study was the first to explore the relationship between Asian dust storm events (ADS) and acute myocardial infarction (AMI) hospital admissions by applying time series models. DESIGN AND SAMPLE: Nationwide population-based hospitalization claims data in Taiwan were used. There were 143,063 AMI admissions during 2000-2009. MEASURES: An autoregressive with exogenous variables (ARX) time series model was used to investigate the dynamic connection between AMI hospital admissions and ADS events. RESULTS: AMI hospitalizations significantly spiked on post-ADS day three. Among the total population, 3.2 more cases of AMI admissions occurred on post-ADS day three. When the data were stratified by age and gender, the same delayed effect was present in the male population, especially those aged 45-64 and over 74. CONCLUSIONS: Our study shows that although an ADS event does not cause an immediate incidence of AMI, storms may increase AMI incidence through a delayed effect. Hence, AMI prevention is not only important during a dust storm, but particularly so in subsequent days. During the days after an ADS, exposure to dust should be minimized by staying indoors as much as possible and by wearing a mask when exposure to dust is unavoidable. This is especially true for working and older adults. Nurses at local public health centers can increase awareness and promote public safety by providing health information to local communities regarding the link between dust storms and AMI.

Using 10-year population data from 2000 through 2009 in Taiwan, this is the first paper to analyze the relationship between margin trading in stock markets and stroke hospitalizations. The results show that 3 and 6 days after an increase of margin trading in the Taiwan stock markets are associated with greater stoke hospitalizations. In general, a 1 % increase in total margin trading positions is associated with an increment of 2.5 in the total number of stroke hospitalizations, where the mean number of hospital admissions is 233 cases a day. We further examine the effects of margin trading by gender and age groups and find that the effects of margin trading are significant for males and those who are 45-74 years old only. In summary, buying stocks with money you do not have is quite risky, especially if the prices of those stocks fall past a certain level or if there is a sudden and severe drop in the stock market. There is also a hidden danger to one's health from margin trading. A person should be cautious before conducting margin trading, because while it can be quite profitable, danger always lurks just around the corner.

BACKGROUND: The highly oncogenic human papillomavirus (HPV) is associated with numerous cancer types. While the role of viruses in the development of certain cancers is well established, the association between HPV infections and prostate cancer remains a subject of ongoing debate. This study aimed to investigate a potential association of prostate cancer with HPV infections utilizing a case-control study. METHODS: We extracted data from the Taiwan Longitudinal Health Insurance Database 2010. We retrieved 5137 patients with prostate cancer as cases and a 3:1 ratio of propensity score-matched patients without prostate cancer (15,411 patients) as controls. Multiple logistic regression analyses were carried out to scrutinize the association of prostate cancer with HPV infections while taking into account age, monthly income category, geographic location and urbanization level of the patient's residence as well as hyperlipidemia, diabetes, hypertension and chronic prostatitis, tobacco use disorder, and alcohol abuse/alcohol dependence syndrome. RESULTS: The data indicate that out of all sampled patients, 1812 (8.8%) had a prior diagnosis of HPV infections before the index date. Among cases and matched controls, HPV infections were diagnosed in 743 (14.5%) and 1069 (6.9%) patients, respectively. The results from the chi-square test demonstrate that individuals with prostate cancer exhibited a significantly higher incidence rate of HPV infections than their control counterparts (p < 0.001). Furthermore, in comparison to controls, individuals with a history of HPV infections had an adjusted odds ratio of 2.321 (95% CI: 2.097~2.568) for developing prostate cancer. Notably, individuals diagnosed with chronic prostatitis were also more likely to be subsequently diagnosed with prostate cancer (adjusted odds ratio=1.586; 95% CI = 1.338~1.879), which aligns with expectations in this context. CONCLUSIONS: We found prostate cancer to be significantly associated with HPV infections, contributing to the mounting body of evidence indicating a plausible connection between the two.
RESUMO
The main purpose of this study was to examine the association between dust storms (DSs) and age-related macular degeneration (AMD) using a 5 year representative national dataset with one million participants, according to information on DS, meteorology, and air pollution in Taiwan. There were 18,855 AMD outpatient cases and 1080 AMD inpatient cases during 2008-2012. A Poisson time-series model was used for the analysis. The results show that AMD cases are significantly associated with exposure to dust storm events. Average daily numbers of wet and dry AMD outpatient cases increased from 6.03 and 4.26 on no-event days to 8.25 and 6.67, 2 days after DSs. Average daily numbers of wet and dry AMD inpatient cases increased from 0.26 and 0.33 on no-event days to 0.58 and 0.75, 1 day after DSs. Both genders and different age groups are all affected by the occurrence of DSs, especially 1 and 2 days after DS events. Women are at a higher risk of outpatient visits and hospitalizations for relatively severe wet AMD. Although AMD highly correlated with age, this study also found that dry AMD outpatient visits in people under the age of 50 were also found to be significantly associated with DS events. In order to protect the health of eyes and avoid AMD, one should reduce or avoid outdoor activities when DS events occur.

Priority setting is a critical process for national healthcare systems that need to allocate limited resources across unlimited healthcare demands. In recent decades, health policymakers have identified the need to combine technical dimensions of priority setting with political dimensions relating to community values. A range of methods for engaging the public in priority setting has been developed, yet there is no consensus around the most effective methodology. A 2014 paper proposed the integration of two methods currently used for soliciting public preferences around health care services: i) an individual survey instrument, Discrete Choice Experiments (DCEs) and ii) Citizen Juries (CJs), a group-based model that incorporates education and deliberative dialogue. This pilot study is among the first to empirically test this integrated method to assess its value across two domains: does the CJ process alter participant preferences and are the consensus values of the CJ captured by the individualistic DCE? The two-part, mixed methods study was administered in Taipei, Taiwan in August of 2016. Twenty-seven participants completed a DCE as a baseline pre-test, ranking a set of attributes in terms of importance for future resource allocation under Taiwan's National Health Insurance System. Twenty of the participants next took part in the integrated CJ-DCE method, which consisted of education and facilitated dialogue through a CJ, followed by retaking the DCE survey. Participant preferences changed after undergoing the CJ process and these new, group-based preferences were reflected in the second DCE, meaning participants did not revert to their original individualistic preferences. The results of this study demonstrate that the integrated CJ-DCE method adds value in allowing an ethically communitarian set of values to be developed and captured via an individualistic methodology. Further testing is needed to investigate the reliability of our findings and how it may be implemented to maximize public acceptance.

Whether the mode of birth delivery correlates with the incidence of postpartum depression (PPD) is still under debate. This study seeks to clarify such a correlation and to further investigate if there are any differences in the likelihood of PPD medical care use among women with and without a history of depression. A logistic regression at two assessment points (6-month and 12-month postpartum) on the National Health Insurance Database in Taiwan is performed. In total, 32,729 women were included who gave first birth from 2007 to 2011 via cesarean section (CS), elective CS, and vaginal delivery, of whom 3580 (10.9%) were diagnosed with a history of depression. Findings show that CS was associated with a higher likelihood of PPD doctor visits regardless of whether the women have a history of depression or not, but elective CS tended to have different impacts for these two groups of women. Mentally healthy women who experienced elective CS had 1.36- and 1.64-times higher risk of PDD medical care use than those who delivered vaginally, whereas previous depressive women undertaking an elective cesarean birth had no significant difference observed in incidences. A notably higher risk of elective CS delivery versus vaginal delivery for mentally healthy women suggests that elective CS is not clinically appropriate, yet it might be an alternative to vaginal delivery with careful counseling for pregnant women who experience a history of depression.
RESUMO
Purpose: Previous studies found that silicosis was majorly associated with occupation-related risks. However, little evidence was available to clarify the relation between Asian dust storm (ADS) and silicosis hospital admissions. This present paper aims to investigate the association between ADS events and hospital admissions for silicosis. Methods: We applied a Poisson time-series regression on the 2000-2012 National Health Insurance Research Database in Taiwan, linking air quality data and ambient temperature data to estimate the impact of ADS on silicosis hospital admissions in the age-specific groups. Results: A total of 2154 hospital admissions were recorded for silicosis in Taiwan, for a daily average number of 0.45. The number rises from 0.43 on a day without ADS to 0.70 on the outbreak day and continues increasing to 0.83 one day after outbreak. Among patients under 45, the effect of ADS appears on the event day as well as several post-event days (lag2-6) at the significant level of p < 0.1. There is also a significant lag effect on post-event day 2 (p < 0.05) for those aged above 74. Conclusion: Asian dust storms do result in a rise of silicosis hospital admissions, particularly for those above 74, those under 45, and for females.
RESUMO
This case-control study aimed to investigate the association of peripheral vestibular disorders (PVD) with subsequent land transport accidents. Data for this study were obtained from Taiwan's National Health Insurance (NHI) dataset. We retrieved 8704 subjects who were newly found to have land transport accidents as cases. Their diagnosis date was used as their index date. Controls were identified by propensity score matching (one per case, n = 8704 controls) from the NHI dataset with their index date being the date of their first health service claim in 2017. Multiple logistic regressions were performed to calculate the prior PVD odds ratio of cases vs. controls. We found that 2.36% of the sampled patients had been diagnosed with PVD before the index date, 3.37% among cases and 1.36% among controls. Chi-square test revealed that there was a significant association between land transport accident and PVD (p < 0.001). Furthermore, multiple logistic regression analysis suggested that cases were more likely to have had a prior PVD diagnosis when compared to controls (OR = 2.533; 95% CI = 2.041-3.143; p < 0.001). After adjusting for age, gender, hypertension, diabetes, coronary heart disease, and hyperlipidemia, cases had a greater tendency to have a prior diagnosis of PVD than controls (OR = 3.001, 95% CI = 2.410-3.741, p < 0.001). We conclude that patients with PVD are at twofold higher odds for land transport accidents.

OBJECTIVE: The objective of this study was to investigate the incidence of mortality risk among children of parents with mental illness. METHOD: The study sample comprised all women giving birth in Taiwan between 1999 and 2001; the dataset was created by linking birth certificate, death certificate, and National Health Insurance research databases. The deaths of the subjects were classified into 5 groups: stillbirths, early neonatal death, late neonatal death, postneonatal death, and early childhood death. A Cox proportional hazard regression was then performed on a pooled 3-year population-based dataset to examine the relationship between parental mental status and survival rates for children younger than 3 years, with the crude and adjusted hazard ratios (HRs) being calculated. RESULTS: Around 2316 affected children were compared with a general population of 605 107. No stillbirths were observed among any children of parents with schizophrenia or affective disorder. Mothers with affective disorder are prone to higher risk of child death, with a crude HR of 4.86 (95% confidence interval, 3.06-7.73), and a reduced adjusted HR of 3.51 (95% confidence interval, 2.22-5.57). However, fathers with affective disorder played no role. Children born to schizophrenic women have a significant higher risk of child death with a crude HR of 2.47, whereas those born to schizophrenic fathers have a similarly high risk with a crude HR of 2.69. CONCLUSION: A focus needs to be placed on the identification and treatment of parental schizophrenia and affective disorder through antenatal and postnatal intervention, so as to reduce mortality risks for children exposed to risk during their first 3 years of life.

This study sets out to examine the relationship between both surgeon and hospital volume and five-year survival rates for breast cancer patients. We performed Cox proportional hazard regressions on a pooled population-based database linking the Taiwan National Health Insurance Research Database with the 'cause of death' data file, covering the three-year period from January 1997 to December 1999. Of the 13,360 breast cancer resection patients in our study sample, the five-year survival rates, by surgeon volume, were 77.3% in the high-volume group (>201 cases), 76.9% in the medium-volume group (45-200), and 69.5% in the low-volume group (Assuntos

RESUMO
OBJECTIVE: To examine the relationship between obstetrician gender and the likelihood of maternal request for cesarean section (CS) within different healthcare institutions (medical centers, regional hospitals, district hospitals, and obstetric and gynecology clinics). STUDY DESIGN: Five years of population-based data from Taiwan covering 857,920 singleton deliveries without a clinical indication for a CS were subjected to a multiple logistic regression to examine the association between obstetrician gender and the likelihood of maternal request for a CS. RESULTS: After adjusting for physician and institutional characteristics, it was found that male obstetricians were more likely to perform a requested CS than female obstetricians in district hospitals (OR=1.53) and clinics (OR=2.26), while obstetrician gender had no discernible associations with the likelihood of a CS upon maternal request in medical centers and regional hospitals. CONCLUSIONS: While obstetrician gender had the greatest association with delivery mode decisions in the lowest obstetric care units, those associations were diluted in higher-level healthcare institutions.

Using nationwide, 7-year population-based data for 1997-2003, we examined marital status to see if it predicted suicide among the ethnic Chinese population of Taiwan. Using cause of death data, with a case-control design, two groups-total adult suicide deaths, n = 17,850, the study group, and adult deaths other than suicide, n = 71,400 (randomly selected from age, sex, and geographic region matched controls, four per suicide)-were studied. Using multiple logistic regression analysis including age-marital status interaction, adjusted estimates show divorced status to be the most detrimental for suicide propensity, with males showing stronger effect size. Females never married, aged below 35 and 65-plus, and widowed 65-plus had lower suicide odds.

OBJECTIVE: To examine the impact of provider competition under global budgeting on the use of cesarean delivery in Taiwan. DATA SOURCES/STUDY SETTING: (1) Quarterly inpatient claims data of all clinics and hospitals with birth-related expenses from 2000 to 2008; (2) file of health facilities' basic characteristics; and (3) regional quarterly point values (price conversion index) for clinics and hospitals, respectively, from the fourth quarter in 1999 to the third quarter in 2008, from the Statistics of the National Health Insurance Administration. STUDY DESIGN: Panel data of quarterly facility-level cesarean delivery rates with provider characteristics, birth volumes, and regional point values are analyzed with the fractional response model to examine the effect of external price changes on provider behavior in birth delivery services. PRINCIPAL FINDINGS: The decline in de facto prices of health services as a result of noncooperative competition under global budgeting is associated with an increase in cesarean delivery rates, with a high degree of response heterogeneity across different types of provider facilities. CONCLUSIONS: While global budgeting is an effective cost containment tool, intensified financial pressures may lead to unintended consequences of compromised quality due to a shift in provider practice in pursuit of financial rewards.

OBJECTIVE: To test whether utilization of infant preventive care services has reduced utilization of inpatient care and to determine whether implementation of Taiwan's National Health Insurance (NHI) has brought about any differences in the utilization of infant health care services. DATA SOURCES: Data were taken from the 1989 and 1996 National Maternal and Infant Health Surveys (NMIHSs). In total, 1662 and 3623 effective samples were used in the study from the 2 years. STUDY DESIGN: We constructed a simultaneous recursive model to obtain efficient estimates by treating preventive care (neonatal care and well-baby care) and inpatient care (hospitalization admissions) as dependent variables. PRINCIPAL FINDINGS: Utilization of neonatal care had strongly negative significant coefficients for the likelihood of being admitted to the hospital. The impact of the NHI was found to be significant. CONCLUSIONS: The hypothesis that the NHI interferes with the effectiveness of preventive care at reducing inpatient care use was not reinforced. Since support from the NHI depends on a balance of push and pull between access to inpatient care and the benefits of preventive care, it can further improve infant health by promoting the benefits of preventive care while making both types of care more accessible.

This study is the first comprehensive analysis to investigate the potential association between stock market fluctuations and attempted suicide events as measured by self-inflicted injuries treated in hospitalization. Using nationwide, 15-year population-based data from 1998 through 2012, we observe that the occurrences for the hospitalizations of attempted suicides are apparently predicted by stock price movements. A low stock price index, a daily fall in the stock index, and consecutive daily falls in the stock index have been shown to be associated with increased risk of hospitalization in patients with attempted suicide. More specifically, stock price index is found to be significant impact on attempted suicide in the 45-54 age groups of both genders, whilst daily change is significant for both genders in the 25-34 and 55-64 age groups and accumulated change is only significant in female aged 25-44 and above 65. On the basis of the results, relevant organizations should consider the suicidal factors that relate prime-working-age and near-retirement-age people to better carry out specific suicide prevention measures, and, meanwhile, encourage those people to pay less attention towards daily stock price movements.

RESUMO
OBJECTIVE: A nationwide population-based dataset was used to explore the association between length of stay (LOS) and 30-day readmission rates for hospitalized patients with schizophrenia in Taiwan. METHODS: The National Health Insurance Research Database was used for the years 2001-2003 and included a total of 29,373 patients with schizophrenia divided equally into four groups according to LOS of index hospitalization. After adjusting for hospital, physician and patient characteristics, a multivariate regression analysis was used to determine the relationship between LOS and 30-day readmission rates. RESULTS: After discharge from their index hospitalization, 12,468 (42.5%) patients with schizophrenia were readmitted within 30 days. The adjusted odds ratio for 30-day readmission rates was increased for shorter LOS. CONCLUSIONS: Healthcare providers should exert caution while trying to reduce LOS within the current cost-conscious environment and balance it with creating a minimal status necessary for discharge.
