Risk of Incident Atrial Fibrillation and Subsequent Use of Oral Anticoagulants in Patients with Dementia.

BACKGROUND: Dementia and atrial fibrillation (AF) have many shared risk factors. Besides, patients with dementia are under-represented in randomized trials, and even if AF is present, oral anticoagulants (OACs) are not prescribed frequently. This study aimed to report the incidence of newly diagnosed AF in dementia patients, and the impacts of use of vitamin K antagonist (VKA; e.g., warfarin) and non-VKA OAC (NOACs) on stroke and bleeding outcomes. METHODS: Our study utilized the Taiwan National Health Insurance Research Database. A total of 554,074 patients with dementia were compared with 554,074 age- and sex-matched patients without dementia regarding the risk of incident AF. Among patients with dementia who experienced incident AF, the risks of clinical events of patients treated with warfarin or NOACs were compared with those without OACs (reference group). RESULTS: The risk of incident AF was greater for patients with dementia compared with those without (adjusted hazard ratio [aHR]: 1.054; 95% confidence interval [CI]: 1.040-1.068 for all types of dementia, aHR: 1.035; 95% CI: 1.020-1.051 for presenile/senile dementia, and aHR: 1.125; 95% CI: 1.091-1.159 for vascular dementia). Among patients with dementia and experienced incident AF, warfarin use was associated with a higher risk of ischemic stroke (aHR: 1.290; 95% CI: 1.156-1.440), intracranial hemorrhage (ICH; aHR: 1.678; 95% CI: 1.346-2.090), and major bleeding (aHR: 1.192; 95% CI: 1.073-1.323) compared with non-OACs. NOAC use was associated with a lower risk of ischemic stroke (aHR: 0.421; 95% CI: 0.352-0.503) and composite risk of ischemic stroke or major bleeding (aHR: 0.544; 95% CI: 0.487-0.608) compared with non-OACs. These results were consistent among the patients after the propensity matching. CONCLUSION: In this large nationwide cohort, the risk of newly diagnosed AF was higher in patients with dementia (all dementia, presenile/senile dementia, and vascular dementia) compared with those without dementia. For patients with dementia who experienced incident AF, NOAC use was associated with a better clinical outcome compared with non-OAC. Patients with dementia require a holistic approach to their care and management, including the use of NOACs to reduce the risks of clinical events.

Terminally ill patients' and their relatives' experiences and behaviors regarding complementary and alternative medicine utilization in hospice palliative inpatient care units: a cross-sectional, multicenter survey.

BACKGROUND: Terminally ill patients often experience exacerbations of diseases that render mainstream medicine ineffective in relieving symptoms, prompting attempts at complementary and alternative medicine (CAM). This study collected data from terminally ill patients and their relatives to determine differences between CAM use, behavioral patterns, and perceptions of health information about CAM. METHODS: A cross-sectional design using a self-administered questionnaire was adopted. Eight medical institutions in Taiwan with inpatient hospice palliative care units were chosen. Ninety-two terminally ill patients and 267 relatives met the inclusion criteria. The questions concerned the experience of CAM use, the kinds of products/services CAM provided, the purpose of CAM use, the source of CAM information, and the perceptions and attitudes toward CAM. RESULTS: Both terminally ill patients and their relatives have a high proportion of lifetime and one-year prevalence of CAM use (88.0% vs. 88.4%; p = 0.929). CAM use for musculoskeletal and neurological discomfort is higher among terminally ill patients than among their relatives. Relatives/friends are the most frequent sources of information on CAM (53.3% vs. 62.2%; p = 0.133). The percentage of terminally ill patients who discontinued mainstream medical treatment because of CAM use was higher than that of their relatives (18.5% vs. 9.3%; p = 0.026). More than half the terminally ill patients and their relatives had never been asked about CAM by medical staff (64.1% vs. 66.7%), nor had they informed medical professionals about the use of CAM products and services (63% vs. 66.9%). Random inquiries by medical professionals may be associated with increased disclosure of CAM use (terminally ill patients: odds ratio, 9.75; 95% confidence interval, 1.97-48.35 vs. relatives: odds ratio, 5.61; 95% confidence interval, 2.66-11.83). CONCLUSIONS: The high prevalence and concealment of CAM use in terminally ill patients should be considered. Medical professionals should establish a friendly and barrier-free communication model, encourage patients to share CAM experiences, and provide evidence-based information on the use of CAM products and services, to reduce the potential damage caused by harmful use.

Family Medicine Academic Workforce of Medical Schools in Taiwan: A Nationwide Survey.

Little is known about family medicine academic workforce in Taiwan, and basic data on this may aid healthcare decision-makers and contribute to the limited literature. We analyzed data from 13 medical schools in Taiwan collected by the Taiwan Association of Family Medicine from June to September 2019, regarding characteristics of medical schools, and total staff, gender, age, degree, working title (adjunct/full-time), academic level, and subspecialty of each current family medicine faculty member. Total 13 medical schools in Taiwan with an undergraduate education program in family medicine, but only nine of the 13 medical schools had family medicine departments, while four still do not. A total of 116 family medicine faculty members ranging from 33-69 years. Of these, most were male (n = 85, 73.3%), with a mean age of 43.3 years. Most faculty members possessed a master's degree (n = 49, 42.2%), were academic lecturers (n = 49, 42.2%), were located in northern Taiwan (n = 79, 68.1%), and subspecialize in gerontology and geriatrics (n = 55, 47.4%) and hospice palliative care (n = 53, 45.7%). Additionally, most family medicine faculty in medical schools were adjunct faculty (n = 90, 77.6%), with only about one-fourth (n = 26, 22.4%) working full-time. Our study provides the most holistic census to date on academic family medicine faculty from all medical schools in Taiwan. The novel information can provide educational leaders, health policy managers, and decision-makers about the current developments of the family medicine departments in Taiwan's medical schools. The basic data will help formulate an effective medical school family medicine education plan and improve the establishment and development of the family medicine faculty workforce to help medical education and national health policy development in the future in Taiwan.

Anesthesia services in Taiwan: A nationwide population-based study.

BACKGROUND: This study was conducted to provide an overview of anesthesia services in Taiwan from 2001 to 2010. METHODS: A retrospective population-based analysis was performed using data from Taiwan's National Health Insurance Research Database for the period 2001 to 2010. The results were stratified by patient sex, patient age, anesthesia type, and hospital setting. Categorical data are presented as totals and percentages. Linear regression was performed to analyze the anesthesia trends. RESULTS: The annual use of anesthesia increased continually from 964,440 instances in 2001 to 1,073,160 in 2010, totaling 10,076,600 cases with a total cost of 25.4 billion USD. The overwhelming majority (83.9%) of anesthesia cases was for anesthesia in an inpatient setting; general anesthesia accounted for 73.8% of anesthesia cases, and female patients outnumbered male patients (52.4% vs 47.6%). The average number of anesthesia cases was 44.2 per thousand of the population annually, but this percentage was much higher in elderly people (100.9 cases per thousand people annually). The annual number of anesthesia cases per thousand of the population increased from 104.4 in 2001 to 113.0 in 2010 in the oldest group (>80 years). By contrast, a considerable decline in use of anesthesia was discovered over the study period among those aged younger than 18 years. CONCLUSION: The use of anesthesia services in Taiwan has increased over the years. The relationships of age with anesthesia volume and cost were found to follow an inverse U-shaped pattern. Elderly people used anesthesia services more frequently. The planning of geriatric anesthesia services deserves attention, especially in continually aging societies such as Taiwan.

Obsessive-Compulsive Disorder and Dementia Risk: A Nationwide Longitudinal Study.

BACKGROUND: Several case reports have suggested an association between obsessive-compulsive disorder (OCD) and dementia. However, the exact relationship remains unclear. METHODS: Using the Taiwan National Health Insurance Research Database, 1,347 patients with OCD (ICD-9-CM code 300.3) aged ≥ 45 years and 13,470 controls matched for age, sex, residence, income, and dementia-related comorbidities were included between 1996 and 2013 for investigation of subsequent dementia from enrollment to the end of 2013. Stratified Cox regression analysis on each matched pair was applied to assess the dementia risk between the OCD and control groups. The analysis for the current study was performed in 2018. RESULTS: Patients with OCD had increased risk of developing any dementia (hazard ratio [HR] = 4.28; 95% confidence interval [CI], 2.96-6.21), Alzheimer's disease (HR = 4.04; 95% CI, 1.55-10.54), and vascular dementia (HR = 3.95; 95% CI, 1.70-9.18) compared with controls. DISCUSSION: Future research on the pathogenic mechanisms and molecular underpinnings of the relationship between OCD and dementia may lead to the development of novel therapeutics.

The element of family medicine in the mega journal of the family medicine specialty: A bibliometric analysis of the journal, Chinese General Practice.

BACKGROUND: With the evolving specialization of modern medicine, family medicine (FM), also known as general practice, is relatively late in being recognized as a formal specialty in most countries of the world. Because many non-FM specialists were recruited into the new specialty in the early stages of FM specialization, the contents of FM specialty journals might, to an extent, reflect the development of the FM specialization. METHODS: In this study, the voluminous journal, Chinese General Practice, which is regarded as the most representative specialty journal, was chosen and analyzed to illustrate the current situation of FM in China. A total of 878 articles, relating to the journal, Chinese General Practice in 2018, were retrieved from the publisher's web site and the original articles were categorized into FM- and non-FM- related articles by 3 board-certified FM doctors. Furthermore, the first authors, as well as the institutions and regions where the first authors worked, and their related specialties, were also analyzed. RESULTS: Of the 634 original articles, 252 (39.7%) articles were FM related. Only 41 FM-related articles were written by authors working at FM departments: 3 at community health service centers, 29 at hospitals, and 9 at universities. Of the 382 non-FM related articles, 159 articles dealt with the topic of internal medicine, followed by traditional Chinese medicine (36), obstetrics and gynecology (28), neurology (27), pediatrics (27), and surgery (21). CONCLUSION: In conclusion, FM publications in China in the study year, as exemplified by Chinese General Practice, were mostly contributed by non-FM authors dealing with non-FM topics. A transition to more FM-oriented development might be anticipated in the near future.

Professionals' experiences and attitudes toward use of Traditional Chinese Medicine in hospice palliative inpatient care units: A multicenter survey in Taiwan.

BACKGROUND: Medical staff may have difficulties in using conventional medicine to manage symptoms among terminally ill patients, including adverse effects of the treatment. Traditional Chinese medicine (TCM) is regarded as a complementary or alternative medicine, and has been increasingly used in the field of palliative medicine in recent years. This study aimed to investigate the experiences of and attitudes toward using TCM among palliative care professionals, and to provide preliminary information about its use in palliative care. METHODS: This was a cross-sectional survey study conducted in eight inpatient hospice wards in Taiwan between December 2014 and February 2016. The questionnaire was self-administered, and was analyzed with descriptive statistics including Pearson's Chi-square test and Fisher's exact test. RESULTS: A total of 251 palliative care professionals responded to the questionnaire, of whom 89.7% and 88.9% believed that the use of TCM could improve the physical symptoms and quality of life in terminally ill patients, respectively. Overall, 59.8%, of respondents suggested that TCM had rare side effects, and 58.2% were worried that TCM could affect the liver and kidney function of patients. In total, 89.7% and 88.0% of professionals agreed there were no suitable clinical practice guidelines and educational programs, respectively, for TCM use in palliative care. CONCLUSIONS: Most of the respondents agreed there was insufficient knowledge, skills-training, and continuing education on the use of TCM in terminally ill patients in Taiwan. These results show that to address patient safety considerations, guidelines about use of TCM in palliative care should be established.

Team-based care improves quality of diabetes care -Family Practice Integrated Care Project in Taiwan.

BACKGROUND: The Family Practice Integrated Care Project (FPICP) is a team-based program in Taiwan initiated in 2003. This study investigates the influence of FPICP on the quality of diabetes care. METHODS: This population-based cohort study used Taiwan's National Health Insurance Administration data on FPICP (fiscal year 2015-2016, with follow-up duration of one year). Participants included diabetic patients aged ≥30 in primary care clinics. We used conditional logistic regression modeling of patient characteristics and annual diabetes examinations and compared FPICP participants with non-participating candidates. Main outcome measures included completion of annual diabetes examinations, including glycated hemoglobin (A1c), low-density lipoprotein (LDL), urine microalbumin (MAU), routine urinalysis (UR), and fundus examination (FE). RESULTS: The sample included 298,208 FPICP participants and 478,778 non-participating candidates. After 1:1 propensity score matching, the examination completion rates for FPICP participants and non-participants, respectively, were 94.4% versus 93.6% in A1c, 84.2% versus 83.8% in LDL, 61.9% versus 60.1% in MAU, 59.2% versus 58.0% in UR, and 30.1% versus 32.4% in FE. CONCLUSION: Our findings indicate that a program like FPICP helps improve the quality of diabetes care through regular examinations of Alc, LDL, MAU, and UR.

To Work at Clinics or at Hospitals? Analysis of Family Physician Recruitment Advertising in Taiwan.

Family physicians act as gatekeepers of the healthcare system and have an indispensable role in providing holistic care in the primary care system. While previous studies had focused on the geographic maldistribution of family physicians, the current study investigated the distribution of job opportunities for family physicians by analyzing recruitment advertisements posted in medical association journals, as an indirect way to observe the marketplace demand for physicians. We collected all the recruitment advertisements for family physicians in the twelve issues of the Taiwan Medical Journal, the official organ of the Taiwan Medical Association, in 2018. In contrast to 124 new trainees annually, 739 advertisements for family physicians were posted within the entire year. After eliminating repeated advertisements, there were 302 distinct advertisements, of which hospitals accounted for 18.9% (n = 57). The job opportunities at hospitals were offered mainly by regional hospitals (n = 26) and community hospitals (n = 29), but only two by medical centers. Family physicians in Taiwan were in great demand not only by primary care clinics but also by hospitals. The role of family physicians in hospitals is worth further study.

Less barium enema, more colonoscopy: A 12-year nationwide population-based study in Taiwan.

BACKGROUND: Colorectal cancer (CRC) is the second most common and third most fatal cancer in Taiwan. To reduce incidence and mortality rates from cancer, including CRC, the Health Promotion Administration in Taiwan initiated the National Program on Cancer Prevention in 2005. For patients who have a positive fecal occult blood test, colonoscopy is recommended, and double-contrast barium enema (BE) is reserved as an alternative for those who cannot receive colonoscopy. In addition, single-contrast BE is sometimes used in pediatrics to evaluate colonic condition. This study evaluated the usage trends of BE and colonoscopy in Taiwan. METHODS: Data from the National Health Insurance Research Database from 2001 to 2013 were used in this study. Patients who received BE and colonoscopy were identified using the procedure codes of the National Health Insurance program. Age-standardized, yearly rates of BE and colonoscopy procedures were calculated. RESULTS: According to the data, the total number of colonoscopies increased 3.7-fold from 2001 to 2013. The compound annual growth rates for BE and colonoscopy were -5.36% and 10.47%, respectively, during the same period. The compound annual growth rates for BE and colonoscopy were -3.89% and 11.64% from 2005 to 2009, and -11.36% and 9.82% from 2010 to 2013, respectively. BE was conducted significantly more frequently than colonoscopy in patients who were aged <12 years and in female patients. CONCLUSION: Professional association guidelines, national cancer prevention programs, patient and physician preferences, and increasing awareness and knowledge of CRC may all contribute to the increasing use of colonoscopy and the dramatic decline in the use of BE in Taiwan.

Integrated therapy decreases the mortality of patients with polymyositis and dermatomyositis: A Taiwan-wide population-based retrospective study.

ETHNOPHARMACOLOGICAL RELEVANCE: The issue of whether integrated treatment with conventional medicine (CM) and herbal medicine (HM) can reduce mortality in patients with polymyositis/dermatomyositis (PM/DM) had not been addressed. AIM OF THE STUDY: In this study, we investigated the effect of integrated therapy on mortality in a retrospective PM/DM cohort in the Taiwan National Health Insurance Research Database (NHIRD). MATERIALS AND METHODS: Patients with PM/DM were retrospectively enrolled from the PM/DM Registry of Catastrophic Illnesses cohort in the Taiwan NHIRD between 1997 and 2011. The patients were divided into an integrated medicine (IM) group that received CM and HM and a non-IM group that received CM alone. The Cox proportional hazards regression model and Kaplan-Meier method were used to evaluate the hazard ratio (HR) for mortality. RESULTS: Three hundred and eighty-five of 2595 patients with newly diagnosed PM/DM had received IM and 99 had received non-IM. The adjusted HR for mortality was lower in the IM group than in the non-IM group (0.42, 95% confidence interval 0.26-0.68, p < 0.001). The adjusted HR for mortality was also lower in the IM group that had received CM plus HM than in the group that received CM alone (0.48, 95% confidence interval 0.28-0.84, p < 0.05). The core pattern of HM prescriptions integrated with methylprednisolone, methotrexate, azathioprine, or cyclophosphamide to decrease mortality included "San-Qi" (Panax notoginseng), "Bai-Ji" (Bletilla striata), "Chen-Pi" (Citrus reticulata), "Hou-Po" (Magnolia officinalis), and "Dan-Shan" (Salvia miltiorrhiza). CONCLUSION: Integrated therapy has reduced mortality in patients with PM/DM in Taiwan. Further investigation of the clinical effects and pharmaceutical mechanism involved is needed.

The Risk of Mortality among Psoriatic Patients with Varying Severity: A Nationwide Population-Based Cohort Study in Taiwan.

Background: Previous studies showed conflicting results regarding the mortality risk in psoriasis patients with respect to disease severity and presence of psoriatic arthritis. This study aimed to determine the mortality risk in patients with mild and severe psoriasis and patients with psoriatic arthritis (PsA). Methods: A nationwide population-based cohort study was conducted based on data from the Taiwan National Health Insurance Research Database between 2002 and 2012. Incident psoriasis subjects were classified into two groups: psoriasis without arthritis and psoriasis with arthritis. Patients who had received systemic therapy and/or phototherapy were classified as having severe psoriasis; otherwise, patients were classified as having mild psoriasis. Control subjects without psoriasis were selected to match each psoriasis patient from the database within the same observational period. Cox proportional hazards analysis was used to compare the hazard ratio (HR) of time to death. Results: A total of 106,701 patients with psoriasis were included in this study. After controlling for demographics and comorbidities, psoriasis patients had a higher mortality risk compared with the control group (HR 1.41; 95% confidence interval (CI) 1.36 to 1.46). Compared with psoriasis alone, the mortality risk was not increased for PsA (HR = 1.01; 95% CI 0.93 to 1.10). Besides, severe psoriasis did not increase mortality risk compared with mild psoriasis (HR = 1.0; 95% CI 0.95 to 1.06). Conclusions: Patients with psoriasis had a higher mortality risk compared with control subjects, whereas psoriasis severity and presence of PsA had no impact on mortality risk in psoriasis patients.

The Evaluation of Professional Divisions of Traditional Chinese Medicine in Taiwan through Patient Visit Records of 2012.

For decades, professional divisions have been represented as the main structural divisions in Western medicine throughout the world. In Taiwan, medical policymakers are also interested in designing professional divisions of traditional Chinese medicine (TCM). Therefore, this study evaluated the current status and potentiality of professional divisions of TCM in Taiwan using data from the year 2012 obtained from the National Health Insurance Research Database; the database provides information regarding age and gender of TCM physicians (TCMPs); total visit counts; contracted medical institution codes; groupings of diseases classified under International Classification of Diseases, Ninth Revision, Clinical Modification codes; numbers of children and female patients seeking treatment; and claim disposition codes used by each TCMP. The results indicated that there were 5522 TCMPs in 2012, and 4876 (90.3%) TCMPs practiced in primary clinics. The proportions of pediatric visits to these TCMPs were mostly below 0.2, and acupuncture or traumatology-related visit proportions were below 0.5. Only a few of the studied Taiwan-based TCMPs practiced gynecology and pediatrics, but most of them performed "internal medicine", or "acupuncture" or "traumatology" treatments. Thus, the number of TCM specialists practicing gynecology or pediatrics is insufficient, indicating that a policy that forms professional divisions of TCM practitioners in Taiwan should be reconsidered.

Visits to Pediatric Clinics by Adult Patients: A Nationwide Survey in Taiwan.

Pediatricians are trained to provide non-surgical medical care to children. Improvements in medical treatments and surgical techniques have extended the survival of children with congenital diseases and chronic illnesses. Consequently, pediatricians may provide continuous medical service to their patients into adulthood. Meanwhile, as Taiwan's birth rate has fallen to one of the lowest in the world, pediatricians are encountering growing competition. As a source of continued revenue, pediatricians could also provide medical care to adults with common diseases and patients with adult-onset chronic diseases. The aim of this study was to investigate the pattern of adult ambulatory visits to pediatric clinics recorded by Taiwan's National Health Insurance (NHI) system during 2000 to 2011. From 1/500 sampling datasets, we found that adult ambulatory visits to pediatric clinics rose steadily and statistically significantly from 16% of total visits to pediatric clinics in 2000 to 32% in 2011. Analysis of the diagnoses associated with adult ambulatory visits to pediatric clinics indicated that the most common diagnoses for such patients at academic medical centers were chronic illnesses, including epilepsy, cardiac and circulatory congenital anomalies, and diabetes. Meanwhile, at physician clinics, airway infections/diseases and gastroenteritis were the most common diagnoses. In an era of low birth rates, our findings contribute to an evidence-based discussion and provide new information that may assist in healthcare policymaking.

Risk of Type 2 Diabetes in Adolescents and Young Adults With Attention-Deficit/Hyperactivity Disorder: A Nationwide Longitudinal Study.

BACKGROUND: Studies have suggested there is an association between attention-deficit/hyperactivity disorder (ADHD) and type 2 diabetes mellitus (DM)-related risk factors, such as obesity, hypertension, and dyslipidemia. However, the association between ADHD and type 2 DM remains unknown. METHODS: Using the Taiwan National Health Insurance Research Database, we enrolled 35,949 adolescents and young adults with ADHD (ICD-9-CM code: 314) and 71,898 (1:2) age- and sex-matched controls from 2002 through 2009 and followed up with them until the end of 2011. Participants who developed type 2 DM during the follow-up period were identified. RESULTS: Adolescents (hazard ratio [HR] = 2.83; 95% CI, 1.96-4.09) and young adults (HR = 3.28; 95% CI, 1.41-7.63) with ADHD had a higher risk of developing type 2 DM than did the controls after adjustment for demographic characteristics, use of ADHD medications and atypical antipsychotics, and medical comorbidities. Individuals with ADHD had a shorter mean ± SD duration between enrollment and onset of type 2 DM (3.17 ± 2.33 vs 4.08 ± 2.11 years, P = .004) during the follow-up compared with the controls. Sensitivity analyses after excluding first-year (HR = 2.36; 95% CI, 1.65-3.38) and first-3-year (HR = 1.92; 95% CI, 1.19-3.09) observation periods were consistent. Long-term use of atypical antipsychotics was associated with a higher likelihood of subsequent type 2 DM (HR = 2.82, 95% CI, 1.74-4.58). DISCUSSION: Adolescents and young adults with ADHD were more likely than non-ADHD controls to develop type 2 DM in later life. In addition, those with ADHD taking atypical antipsychotics exhibited a higher risk. Although correlation does not equal causation, our findings merit further study about the relationship between ADHD and type 2 DM.

Post-traumatic stress disorder and risk of osteoporosis: A nationwide longitudinal study.

Several studies suggested a relationship between stress and related mental illnesses, such as depression and osteoporosis. However, it was unclear whether patients with post-traumatic stress disorder (PTSD) were at risk of developing osteoporosis in later life. In this study, 6,041 patients with PTSD and 24,164 age- or sex-matched controls were enrolled between 2002 and 2009 in our study and followed up to the end of 2011. Cases of osteoporosis were identified during the follow-up. Patients with PTSD had an elevated likelihood of developing osteoporosis (HR: 2.66, 95% CI [1.91, 3.71]) in later life compared with the controls. Sensitivity tests after excluding the first year observation (HR: 2.46, 95% CI [1.72, 3.53]) and the first 3-year observation (HR: 1.88, 95% CI [1.18, 3.01]) were consistent. Patients with PTSD had a higher risk of developing osteoporosis at an earlier age compared with those without PTSD. Further studies would be necessary to clarify the pathophysiology between PTSD and osteoporosis.

Risk of suicide attempts in adolescents and young adults with attention-deficit hyperactivity disorder: a nationwide longitudinal study.

BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) increases the risk of suicidal behaviours through psychiatric comorbidities; however, a significant direct association has not been observed between ADHD and suicide attempts. Aims To evaluate the risk of suicide attempt in adolescents and young adults with ADHD. METHOD: Using a nationwide, population-based insurance claims database, this longitudinal cohort study enrolled 20 574 adolescents and young adults with ADHD and 61 722 age- and gender-matched controls between 2001 and 2009. Any suicide attempt was identified from enrolment to 31 December 2011. The association between ADHD medications and the likelihood of suicide attempt was assessed. RESULTS: ADHD was an independent risk factor for any suicide attempt (hazard ratio = 3.84, 95% CI = 3.19-4.62) and repeated suicide attempts (hazard ratio = 6.52, 95% CI = 4.46-9.53). Subgroup analyses of men, women, adolescents and young adults demonstrated the same trend. Methylphenidate or atomoxetine treatment did not increase the risk of suicide attempt or repeated suicide attempts. Long-term methylphenidate treatment was associated with a significantly decreased risk of repeated suicide attempts in men (hazard ratio = 0.46, 95% CI = 0.22-0.97). CONCLUSION: ADHD was a risk factor for suicide attempt and a stronger predictor of repeated suicide attempts, independent of comorbidities. Further investigation is warranted to explore the mechanism underlying the association between ADHD and suicidal behaviours. Declaration of interest None.

Differences in do-not-resuscitate orders, hospice care utilization, and late referral to hospice care between cancer and non-cancer decedents in a tertiary Hospital in Taiwan between 2010 and 2015: a hospital-based observational study.

BACKGROUND: In 2009, the Taiwanese national health insurance system substantially expanded hospice coverage for terminal cancer patients to include patients with end-stage brain, dementia, heart, lung, liver, and kidney diseases. This study aimed to evaluate differences in do-not-resuscitate (DNR) status and hospice care utilization between terminal cancer patients and advanced non-cancer patients after the policy change. METHODS: Data were obtained from the Death and Hospice Palliative Care Database of Taipei Veterans General Hospital in Taiwan. The differences between cancer and non-cancer patients who died in this hospital between 2010 and 2015 were analyzed in terms of patient characteristics, rates of DNR orders, hospice care utilization, number of living days after DNR order, duration of survival (DOS) after hospice care enrollment, and the rate of late referral to hospice care. RESULTS: Data for 8459 patients who died of cancer and major non-cancer terminal diseases were included. DNR order rate, hospice care utilization rate, and DOS were significantly higher for cancer patients than for non-cancer patients (p < 0.001, p < 0.001, and p < 0.001, respectively). The number of living days after DNR order and the late referral rate were significantly higher for non-cancer decedents than for cancer decedents (p < 0.001 and p < 0.001, respectively). From 2010 to 2015, there were significantly increasing trends in the hospice utilization rate, number of living days after DNR order, and rate of late referral for the cancer group (p < 0.001, p = 0.001, and p < 0.001, respectively). For the non-cancer group, there were significantly increasing trends in the rate of DNR order, hospice utilization rate, and number of living days after DNR order (p < 0.001, p < 0.001, and p = 0.029, respectively). CONCLUSIONS: Further guidelines should be developed to help clinicians to promptly refer terminal cancer and non-cancer patients to hospice care. Considering the lower hospice utilization rate and the growing need for hospice care among terminal non-cancer patients, policymakers should consider how to improve the relevant levels of professional care to enhance the accessibility and availability of hospice care in Taiwan.

Lifetime Risks, Projected Numbers, and Adverse Outcomes in Asian Patients With Atrial Fibrillation: A Report From the Taiwan Nationwide AF Cohort Study.

BACKGROUND: Most data on the clinical epidemiology of atrial fibrillation (AF) come from Western populations, and data for Asians are limited. We investigated the lifetime risk and projected number of AF among Asians. The annual risks of adverse events among patients with AF, time trends, and the risks compared with patients without AF were analyzed. METHODS: Between 2000 and 2011, 289,559 patients aged ≥ 20 years experienced new-onset AF in Taiwan. The incidence, prevalence, and lifetime risk of AF were calculated. The risk of adverse events among patients with AF were analyzed and compared with that of age- and sex-matched patients without AF. RESULTS: The incidence of AF in year 2011 was 1.51 per 1,000 person-years, with a lifetime risk of AF being appropriately 1 in 7 for subjects aged > 20 years. The prevalence of AF is estimated to be 4.01% in 2050. Compared with patients without AF, AF was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 2.61), heart failure (aHR, 3.31), ischemic stroke (aHR, 3.34), dementia (aHR, 1.56), sudden cardiac death (aHR, 1.83), and myocardial infarction (aHR, 1.62); all P < .01. The risks of ischemic stroke, heart failure, and mortality were especially higher compared with patients without AF in the initial period (approximately 6 months) after AF was first diagnosed. CONCLUSIONS: The burden of AF among Asian patients is increasing, with a lifetime risk of AF being 1 in 7. Optimized management of any associated comorbidities should be part of the holistic management approach for AF.
