Prevalence of exposure to benzodiazepines among pregnant women in Taiwan: A nationwide longitudinal study.

Although more than one hundred studies have examined the prevalence of the use of benzodiazepines and benzodiazepine-like Z-hypnotics (BZDs) among pregnancy events, further analysis of the effects of dosage or type of BZDs is needed. The aim of this study was to examine the prevalence rate of BZDs use in pregnancy events, stratified by trimester over time, with characteristics of the dosage and type of BZDs. This is a retrospective population study based on linking three national databases. We examined the prevalence rates from 2004 to 2017, and contrasted the results based on >0 defined daily dose (DDD) and ≥0.5 DDD. We identified 2,630,944 pregnancy events with live births; 89,897 (3.4%) of the associated pregnancy events had used some form of BZD during pregnancy. The prevalence of BZDs use, as defined by >0 DDD, decreased from 4.1% in 2004 to 2.9% in 2017, indicating a decrease in sporadic use and an increase in stable use within therapeutic doses. Meanwhile, BZDs use defined by ≥0.5 DDD increased from 0.1% in 2004 to 0.4% in 2017. Zolpidem was the most frequently prescribed BZDs, as defined by >0 DDD or ≥0.5 DDD. This national cohort study demonstrates the importance of average dosage in the definition of BZDs use in pregnancy events, and it found opposite trends in the prevalence of use between different dosages.

Nephrologist Follow-Up Care of Patients With Acute Kidney Disease Improves Outcomes: Taiwan Experience.

OBJECTIVES: Acute kidney injury (AKI) and acute kidney disease (AKD) are a continuum on a disease spectrum and frequently progress to chronic kidney disease. Benefits of nephrologist subspecialty care during the AKD period after AKI are uncertain. METHODS: Patients with AKI requiring dialysis who subsequently became dialysis independent and survived for at least 90 days, defined as the AKD period, were identified from the Taiwanese population's health insurance database. Cox proportional hazard models using death as the competing risk before and after propensity-score matching were applied to evaluate various endpoints. RESULTS: Among a total of 20 260 patients with AKI requiring dialysis who became dialysis independent, only 7550 (37.3%) patients were followed up with by a nephrologist (F/Unephrol group) during the AKD period. During a mean 4.04 ± 3.56 years of follow-up, the patients in the F/Unephrol group were more often administered statin, antihypertensives, angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB), diuretics, antiplatelet agents, and antidiabetic agents. The patients in the F/Unephrol group had a lower mortality rate (hazard ratio [HR] = 0.87, P < .001) and were less likely to have major adverse cardiovascular events (MACE) (subdistribution HR [sHR] = 0.85, P < .001), congestive heart failure (CHF) (sHR = 0.81, P < .001), and severe sepsis (sHR = 0.88, P = .008) according to the Cox proportional model after adjusting for mortality as a competing risk. During the AKD period, an increase in the frequency of nephrology visits was associated with improved outcomes. CONCLUSIONS: In this population-based cohort, even after weaning off acute dialysis, only a minority of patients visited a nephrologist during the AKD period. We showed that nephrology follow-up is associated with a decrease in MACE, CHF exacerbations, and sepsis, as well as lower mortality; thus it may improve outcomes in patients with AKD.

Risk of active tuberculosis among COPD patients treated with fixed combinations of long-acting beta2 agonists and inhaled corticosteroids.

OBJECTIVES: To investigate the incidence of active tuberculosis (TB) among COPD patients using fluticasone/salmeterol or budesonide/formoterol, and to identify any differences between these two groups of patients. METHODS: The study enrolled COPD patients from Taiwan NHIRD who received treatment with fluticasone/salmeterol or budesonide/formoterol for > 90 days between 2004 and 2011. The incidence of active TB was the primary outcome. RESULTS: Among the intention-to-treat population prior to matching, the incidence rates of active TB were 0.94 and 0.61% in the fluticasone/salmeterol and budesonide/formoterol groups, respectively. After matching, the fluticasone/salmeterol group had significantly higher rates of active TB (adjusted HR, 1.41, 95% CI, 1.17-1.70) compared with the budesonide/formoterol group. The significant difference between these two groups remained after a competing risk analysis (HR, 1.45, 95% CI, 1.21-1.74). Following propensity score matching, the fluticasone/salmeterol group had significantly higher rates of active TB compared with the budesonide/formoterol group (adjusted HR, 1.45, 95% CI, 1.14-1.85). A similar trend was observed after a competing risk analysis (HR, 1.44, 95% CI, 1.19-1.75). A higher risk of active TB was observed in the fluticasone/salmeterol group compared with the budesonide/formoterol group across all subgroups, but some differences did not reach statistical significance. CONCLUSION: Fluticasone/salmeterol carried a higher risk of active TB compared with budesonide/formoterol among COPD patients.

Risk of Sepsis and Mortality Among Patients With Chronic Obstructive Pulmonary Disease Treated With Angiotensin-Converting Enzyme Inhibitors or Angiotensin Receptor Blockers.

OBJECTIVES: This study aimed to compare the effect of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on the risk and outcomes of sepsis in patients with chronic obstructive pulmonary disease. DESIGN: A retrospective study. SETTING: Taiwan's National Health Insurance Research Database. PATIENTS: All patients with chronic obstructive pulmonary disease who received angiotensin-converting enzyme inhibitors or angiotensin receptor blockers for more than 90 days between 2000 and 2005 were recruited for this study. Pairwise matching (1:1) of the angiotensin-converting enzyme inhibitor and angiotensin receptor blocker groups resulted in two similar subgroups with 5,959 patients in each. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was sepsis, and the secondary outcome was death. The occurrence rate of sepsis was 3.67 per 100 person-years for the patients receiving angiotensin-converting enzyme inhibitors and 2.87 per 100 person-years for those receiving angiotensin receptor blockers. In addition, the patients receiving angiotensin-converting enzyme inhibitors had a higher risk of septic shock (adjusted hazard ratio, 1.45; 95% CI, 1.26-1.67) and mortality (adjusted hazard ratio, 1.31; 95% CI, 1.22-1.40) than those receiving angiotensin receptor blockers. No matter whether the patients had prior severe exacerbation before the index date, those receiving angiotensin-converting enzyme inhibitors had a higher risk of sepsis, septic shock, and mortality than those receiving angiotensin receptor blockers (all p < 0.001). CONCLUSIONS: Angiotensin receptor blockers were associated with lower rates of sepsis and mortality than angiotensin-converting enzyme inhibitors in the patients with chronic obstructive pulmonary disease. The similar findings were also noted in subgroup analysis.

Individualized home-based exercise and nutrition interventions improve frailty in older adults: a randomized controlled trial.

BACKGROUND: Frail older adults are predisposed to multiple comorbidities and adverse events. Recent interventional studies have shown that frailty can be improved and managed. In this study, effective individualized home-based exercise and nutrition interventions were developed for reducing frailty in older adults. METHODS: This study was a four-arm, single-blind, randomized controlled trial conducted between October 2015 and June 2017 at Miaoli General Hospital in Taiwan. Overall, 319 pre-frail or frail older adults were randomly assigned into one of the four study groups (control, exercise, nutrition, and exercise plus nutrition [combination]) and followed up during a 3-month intervention period and 3-month self-maintenance period. Improvement in frailty scores was the primary outcome. Secondary outcomes included improvements in physical performance and mental health. The measurements were performed at baseline, 1 month, 3 months, and 6 months. RESULTS: At the 6-month measurement, the exercise (difference in frailty score change from baseline: - 0.23; 95% confidence interval [CI]: - 0.41, - 0.05; p = 0.012), nutrition (- 0.28; 95% CI: - 0.46, - 0.11; p = 0.002), and combination (- 0.34; 95% CI: - 0.52, - 0.16; p <  0.001) groups exhibited significantly greater improvements in the frailty scores than the control group. Significant improvements were also observed in several physical performance parameters in the exercise, nutrition, and combination groups, as well as in the 12-Item Short Form Health Survey mental component summary score for the nutrition group. CONCLUSIONS: The designated home-based exercise and nutrition interventions can help pre-frail or frail older adults to improve their frailty score and physical performance.

Risk of sepsis in patients with primary aldosteronism.

BACKGROUND: The interaction between hyperaldosteronism and immune dysfunction has been reported and glucocorticoid co-secretion is frequently found in primary aldosteronism (PA). The aforementioned conditions raise the possibility of the infection risk; however, clinical episodes of sepsis have not been reported in PA. METHODS: Using Taiwan's National Health Insurance Research Database between 1997 and 2009, we identified PA and aldosterone-producing adenoma (APA) matched with essential hypertension (EH) at a 1:1 ratio by propensity scores. The incidences of sepsis and mortality after the index date were evaluated, and the risk factors of outcomes were identified using adjusted Cox proportional hazards models and taking mortality as a competing risk. RESULTS: We enrolled 2448 patients with PA (male, 46.08%; mean age, 48.4 years). There were 875 patients who could be ascertained as APA. Taking mortality as the competing risk, APA patients had a lower incidence of sepsis than their matched EH patients (hazard ratio (HR) 0.29; P < 0.001) after target treatments. Patients receiving adrenalectomy showed a benefit of decreasing the risk of sepsis (PA vs EH, HR 0.14, P = 0.001; APA vs EH, HR 0.16, P = 0.003), but mineralocorticoid receptor antagonist treatment may differ. Compared with matched control cohorts, patients with APA had a lower risk of all-cause mortality (PA, adjusted HR 0.84, P = 0.050; APA, adjusted HR 0.31, P < 0.001) after target treatments. CONCLUSIONS: Our study demonstrated that patients with PA/APA who underwent adrenalectomy could attenuate the risk of sepsis compared with their matched EH patients. We further found that APA patients with target treatments could decrease all-cause mortality compared with EH patients.

Frequency of Early Predialysis Nephrology Care and Postdialysis Cardiovascular Events.

BACKGROUND: Patients with kidney failure are at a high risk for cardiovascular events. Predialysis nephrology care has been reported to improve postdialysis survival, but its effects on postdialysis major adverse cardiovascular events (MACEs) have not been comprehensively studied. STUDY DESIGN: Observational cohort study. SETTING & PARTICIPANTS: We used data from the National Health Insurance Research Database in Taiwan. Adult patients who initiated maintenance dialysis therapy in 1999 to 2010 were enrolled. PREDICTOR: We created 3 subtypes of predialysis nephrology care based on the time between the first nephrology visit and the initiation of dialysis therapy: early frequent (duration ≥ 6 months; at least 1 nephrology visit every 3 months), early infrequent (duration ≥ 6 months, <1 nephrology visit every 3 months), and late (duration < 6 months). OUTCOMES: MACE was defined using the primary diagnosis in hospitalization records of acute myocardial infarction, acute heart failure, acute stroke, or sudden death. MEASUREMENTS: We investigated the associations of different subtypes of nephrology care with postdialysis 1-year MACEs. RESULTS: Among the 60,329 eligible patients, 24,477 (40.6%) had early frequent, 12,763 (21.2%) had early infrequent, and 23,089 (38.3%) had late nephrology care. Compared to the late-nephrology-care group, the early-frequent group was associated with an ∼10% lower risk for 1-year MACEs (HR of 0.89 [95% CI, 0.82-0.96] for first MACE and relative risk of 0.91 [95% CI, 0.84-0.98] for recurrent MACEs). However, the early-infrequent-care group had similar risks for MACEs as the late group (HR of 0.95 [95% CI, 0.86-1.05] for first MACE and relative risk of 0.94 [95% CI, 0.86-1.02] for recurrent MACEs). LIMITATIONS: Lack of physical and biochemical information because of inherent limitations from administrative claims data. CONCLUSIONS: Early frequent nephrology care for 6 or more months before the initiation of long-term dialysis therapy may improve 1-year postdialysis major cardiovascular outcomes.

Short- and long-term use of medication for psychological distress after the diagnosis of cancer.

PURPOSE: This study investigated the short- and long-term use of medication for psychological distress after the diagnosis of cancer. METHODS: Longitudinal data from the Taiwan National Health Insurance database were used to follow 35,137 cancer patients for 2.5 years after being diagnosed in 2006 and 2007. RESULTS: Among those patients who survived for at least 180 days, 20.9 % had used psychotropic medications; sedatives were the most frequently prescribed (14.3 %), followed by antidepressants (5.5 %), anxiolytics (3.6 %), and antipsychotics (2.7 %). Lung cancer, prostate cancer, and oral cancer showed a significant association with the regular use of medication in the first 180 days. Among patients who survived for at least 2.5 years, 4.8 % still used psychotropic medication on a regular basis. Lung cancer and prostate cancer were associated with such prolonged use. CONCLUSIONS: This longitudinal study found that the type of cancer was significantly associated with the use of psychotropic drugs after the diagnosis was made. It provided information about the trajectory of that use and found that a small number of patients were still using those medications after 2.5 years.

Gender and age disparity in the initiation of life-supporting treatments: a population-based cohort study.

BACKGROUND: The relationships between age and the life-supporting treatments use, and between gender and the life-supporting treatments use are still controversial. Using extracorporeal membrane oxygenation as an example of life-supporting treatments, the objectives of this study were: (1) to examine the relationship between age and the extracorporeal membrane oxygenation use; (2) to examine the relationship between age and the extracorporeal membrane oxygenation use; and (3) to deliberate the ethical and societal implications of age and gender disparities in the initiation of extracorporeal membrane oxygenation. METHODS: This is a population-based, retrospective cohort study. Taiwan's extracorporeal membrane oxygenation cases from 2000 to 2010 were collected. The annual incidence rate of extracorporeal membrane oxygenation use adjusting for both age and gender distribution for each year from 2000 to 2010 was derived using the population of 2000 as the reference population. The trend of extracorporeal membrane oxygenation use was examined using time-series linear regression analysis. We conducted joinpoint regression for estimating the trend change of extracorporeal membrane oxygenation use. RESULTS: The trends of extracorporeal membrane oxygenation use both for different gender groups, and for different age groups have been significantly increasing over time. Men were more likely to be supported by extracorporeal membrane oxygenation than women. Women's perspectives toward life and death, and women's perception of well-being may be associated with the phenomenon. In addition, the patients at the age of 65 or older were more likely to be supported by extracorporeal membrane oxygenation than those younger than 65. Family autonomy/family-determination, and the Confucian tradition of filial piety and respecting elders may account for this phenomenon. CONCLUSIONS: This study showed gender and age disparities in the initiation of extracorporeal membrane oxygenation use in Taiwan, which may be accounted for by the cultural and societal values in Taiwan. For a healthcare professional who deals with patients'/family members' medical decision-making to initiate life-supporting treatments, he/she should be sensitive not only to the legality, but also the societal and ethical issues involved.

The Association Between Internet Use and Ambulatory Care-Seeking Behaviors in Taiwan: A Cross-Sectional Study.

BACKGROUND: Compared with the traditional ways of gaining health-related information from newspapers, magazines, radio, and television, the Internet is inexpensive, accessible, and conveys diverse opinions. Several studies on how increasing Internet use affected outpatient clinic visits were inconclusive. OBJECTIVE: The objective of this study was to examine the role of Internet use on ambulatory care-seeking behaviors as indicated by the number of outpatient clinic visits after adjusting for confounding variables. METHODS: We conducted this study using a sample randomly selected from the general population in Taiwan. To handle the missing data, we built a multivariate logistic regression model for propensity score matching using age and sex as the independent variables. The questionnaires with no missing data were then included in a multivariate linear regression model for examining the association between Internet use and outpatient clinic visits. RESULTS: We included a sample of 293 participants who answered the questionnaire with no missing data in the multivariate linear regression model. We found that Internet use was significantly associated with more outpatient clinic visits (P=.04). The participants with chronic diseases tended to make more outpatient clinic visits (P<.01). CONCLUSIONS: The inconsistent quality of health-related information obtained from the Internet may be associated with patients' increasing need for interpreting and discussing the information with health care professionals, thus resulting in an increasing number of outpatient clinic visits. In addition, the media literacy of Web-based health-related information seekers may also affect their ambulatory care-seeking behaviors, such as outpatient clinic visits.

Trend and factors associated with healthcare use and costs in type 2 diabetes mellitus: a decade experience of a universal health insurance program.

BACKGROUND: Little is known about how a universal National Health Insurance program with cost-containment strategies affect costs and quality of diabetes care. OBJECTIVES: To examine the trends of healthcare use and costs for patients with type 2 diabetes mellitus (T2DM) in Taiwan over the last decade, and to identify factors associated with high healthcare cost and poor diabetes care. RESEARCH DESIGN: We delineated the pattern of healthcare use and costs for T2DM in 2000-2010. Generalized linear and logistic regression models were used to identify factors associated with medical costs and diabetes care. SUBJECTS: Representative adult T2DM patients and age-matched and sex-matched nondiabetes individuals were selected from the 2000, 2005, and 2010 National Health Insurance Research Databases. MEASURES: Healthcare use included physician visits, hospital admissions, and antidiabetic drug prescriptions. Indicators of diabetes management included completeness of recommended diabetes tests and medication adherence, assessed using medication possession ratio. RESULTS: The total healthcare cost per diabetes patient was approximately 2.8-fold higher than that for nondiabetes individual. The growth of healthcare cost per diabetes patient was significantly contained by about 3694 New Taiwan dollars (3.6%) between 2005 and 2010, but diabetes care improved over the decade. Diabetes duration, income, place of residence, continuity of care, and enrollment to a pay-for-performance program were associated with healthcare costs and diabetes management. Some public health measures implemented to support diabetes care were also discussed. CONCLUSIONS: Healthcare costs could be controlled without sacrificing the quality of diabetes care by implementing pay-for-performance programs and effective health policies favorable for diabetes care.

Long-term risk of coronary events after AKI.

The incidence rate of AKI in hospitalized patients is increasing. However, relatively little attention has been paid to the association of AKI with long-term risk of adverse coronary events. Our study investigated hospitalized patients who recovered from de novo dialysis-requiring AKI between 1999 and 2008 using patient data collected from inpatient claims from Taiwan National Health Insurance. We used Cox regression with time-varying covariates to adjust for subsequent CKD and ESRD after discharge. Results were further validated by analysis of a prospectively constructed database. Among 17,106 acute dialysis patients who were discharged, 4869 patients recovered from dialysis-requiring AKI (AKI recovery group) and were matched with 4869 patients without AKI (non-AKI group). The incidence rates of coronary events were 19.8 and 10.3 per 1000 person-years in the AKI recovery and non-AKI groups, respectively. AKI recovery associated with higher risk of coronary events (hazard ratio [HR], 1.67; 95% confidence interval [95% CI], 1.36 to 2.04) and all-cause mortality (HR, 1.67; 95% CI, 1.57 to 1.79) independent of the effects of subsequent progression to CKD and ESRD. The risk levels of de novo coronary events after hospital discharge were similar in patients with diabetes alone and patients with AKI alone (P=0.23). Our results reveal that AKI with recovery associated with higher long-term risks of coronary events and death in this cohort, suggesting that AKI may identify patients with high risk of future coronary events. Enhanced postdischarge follow-up of renal function of patients who have recovered from temporary dialysis may be warranted.

The over-optimistic portrayal of life-supporting treatments in newspapers and on the Internet: a cross-sectional study using extra-corporeal membrane oxygenation as an example.

BACKGROUND: Extra-corporeal membrane oxygenation has been introduced to clinical practice for several decades. It is unclear how internet and newspapers portray the use of extra-corporeal membrane oxygenation. This study were: (1) to quantify the coverage of extra-corporeal membrane oxygenation use in newspapers and on the Internet; (2) to describe the characteristics of extra-corporeal membrane oxygenation users presented in newspaper articles and the Internet web pages in comparison with those shown in extra-corporeal membrane oxygenation studies in Taiwan; and (3) to examine the survival rates of extra-corporeal membrane oxygenation users presented in newspaper articles and the Internet web pages in comparison with those in Taiwan and in the Extracorporeal Life Support Registry Report International Summary for January 2014. METHODS: All issues of Taiwan's four major newspapers from 2006 to 2010 were reviewed. In October 2011, a search of Internet web pages was performed based on the subjects of "yeh-ko-mo" (extra-corporeal membrane oxygenation in Traditional Chinese), "ECMO", and "extra-corporeal membrane oxygenation." All the Internet web pages and newspaper articles recounting the use of extra-corporeal membrane oxygenation were reviewed. The information, such as patient characteristic and the status at hospital discharge, was collected. RESULTS: The survival rate of extra-corporeal membrane oxygenation use shown on the Internet (83.97%) was significantly higher than all the survival rates reported in Taiwan's literature (p < .01) and in the Extracorporeal Life Support Registry Report International Summary for January 2014 (p < .01). In addition, the survival rate of extra-corporeal membrane oxygenation use shown in newspapers (61.54%) was significantly higher than the average survival rate (43%) reported in Taiwan's literature, the pediatric average survival rate (51%), and the adult average survival rate (47%) in the Extracorporeal Life Support Registry Report International Summary for January 2014. CONCLUSIONS: Internet and newspapers both showed over-optimistic survival to hospital discharge for patients sustained by extra-corporeal membrane oxygenation. Internet was more likely to provide optimistic information for aggressive life-supporting treatments such as extra-corporeal membrane oxygenation than newspapers as indicated by survival to hospital discharge.

Significant social events and increasing use of life-sustaining treatment: trend analysis using extracorporeal membrane oxygenation as an example.

BACKGROUND: Most studies have examined the outcomes of patients supported by extracorporeal membrane oxygenation as a life-sustaining treatment. It is unclear whether significant social events are associated with the use of life-sustaining treatment. This study aimed to compare the trend of extracorporeal membrane oxygenation use in Taiwan with that in the world, and to examine the influence of significant social events on the trend of extracorporeal membrane oxygenation use in Taiwan. METHODS: Taiwan's extracorporeal membrane oxygenation uses from 2000 to 2009 were collected from National Health Insurance Research Dataset. The number of the worldwide extracorporeal membrane oxygenation cases was mainly estimated using Extracorporeal Life Support Registry Report International Summary July 2012. The trend of Taiwan's crude annual incidence rate of extracorporeal membrane oxygenation use was compared with that of the rest of the world. Each trend of extracorporeal membrane oxygenation use was examined using joinpoint regression. RESULTS: The measurement was the crude annual incidence rate of extracorporeal membrane oxygenation use. Each of the Taiwan's crude annual incidence rates was much higher than the worldwide one in the same year. Both the trends of Taiwan's and worldwide crude annual incidence rates have significantly increased since 2000. Joinpoint regression selected the model of the Taiwan's trend with one joinpoint in 2006 as the best-fitted model, implying that the significant social events in 2006 were significantly associated with the trend change of extracorporeal membrane oxygenation use following 2006. In addition, significantly social events highlighted by the media are more likely to be associated with the increase of extracorporeal membrane oxygenation use than being fully covered by National Health Insurance. CONCLUSIONS: Significant social events, such as a well-known person's successful extracorporeal membrane oxygenation use highlighted by the mass media, are associated with the use of life-sustaining treatment such as extracorporeal membrane oxygenation.

Percutaneous Coronary Intervention With a Drug-Eluting Stent Versus Coronary Artery Bypass Grafting in Patients Receiving Dialysis: A National Study From Taiwan.

Rationale & Objective: We aimed to study the comparative effectiveness of percutaneous coronary intervention with drug-eluting stent and coronary artery bypass grafting in patients receiving dialysis. Study Design: This was a retrospective observational cohort study. Setting & Participants: This population-based study identified patients receiving dialysis hospitalized for coronary revascularization between January 1, 2009 and December 31, 2015, in the Taiwan National Health Insurance Research Database. Exposures: Patients received percutaneous coronary intervention with drug-eluting stent versus coronary artery bypass grafting. Outcomes: The study outcomes were all-cause mortality, in-hospital mortality, and repeat revascularization. Analytical Approach: Propensity scores were used to match patients. Cox proportional hazards models and logistic regression models were constructed to examine associations between revascularization strategies and mortality. Interval Cox models were fitted to estimate time-varying hazards during different periods. Results: A total of 1,840 propensity score-matched patients receiving dialysis were analyzed. Coronary artery bypass grafting was associated with higher in-hospital mortality (coronary artery bypass grafting vs percutaneous coronary intervention with drug-eluting stent; crude mortality rate 12.5% vs 3.3%; adjusted OR, 5.22; 95% CI, 3.42-7.97; P < 0.001) and longer hospitalization duration (median [IQR], 20 [14-30] days vs 3 [2-8] days; P < 0.001). After discharge, repeat revascularization, acute coronary syndrome, and repeat hospitalization all occurred more frequently in the percutaneous coronary intervention with drug-eluting stent group. Importantly, with a median follow-up of 2.8 years, coronary artery bypass grafting was significantly associated with a higher risk of all-cause overall mortality (adjusted HR, 1.19; 95% CI, 1.05-1.35; P = 0.006) in the multivariable Cox proportional hazard model. Sensitivity and subgroup analyses yielded consistent results. Limitations: This was an observational study with mainly Asian ethnicity. Conclusions: Percutaneous coronary intervention with drug-eluting stent may be associated with better survival than coronary artery bypass grafting in patients receiving dialysis. Future studies are warranted to confirm this finding.

Although coronary artery bypass grafting offers better long-term survival in the general population than percutaneous coronary intervention with drug-eluting stent, patients receiving dialysis may be too frail to tolerate the increased perioperative mortality risk of coronary artery bypass grafting. In this retrospective study in a national cohort of patients receiving dialysis from Taiwan, percutaneous coronary intervention with drug-eluting stent is associated with lower in-hospital mortality and better long-term survival when compared with coronary artery bypass grafting. Subsequent acute coronary syndrome, repeat revascularization, and rehospitalization were noted more frequently in the percutaneous coronary intervention with drug-eluting stent group. These findings may suggest percutaneous coronary intervention with drug-eluting stent as a safe revascularization strategy for patients receiving dialysis.

Recovery Dynamics and Prognosis After Dialysis for Acute Kidney Injury.

Importance: The interplay among baseline kidney function, severity of acute kidney disease (AKD), and post-AKD kidney function has significant associations with patient outcomes. However, a comprehensive understanding of how these factors are collectively associated with mortality, major adverse cardiac events (MACEs), and end-stage kidney disease (ESKD) in patients with dialysis-requiring acute kidney injury (AKI-D) is yet to be fully explored. Objective: To investigate the associations of baseline kidney function, AKD severity, and post-AKD kidney function with mortality, MACEs, and ESKD in patients with AKI-D. Design, Setting, and Participants: This nationwide, population-based cohort study of patients with AKI-D was conducted between January 1, 2015, and December 31, 2018, using data from various health care settings included in the Taiwan nationwide population-based cohort database. Data analysis was conducted from April 28, 2022, to June 30, 2023. Exposure: Exposure to severe AKI and baseline and post-AKD kidney function. Main Outcomes and Measures: The primary outcomes were all-cause mortality and incident MACEs, and secondary outcomes were risks of permanent dialysis and readmission. Results: A total of 6703 of 22 232 patients (mean [SD] age, 68.0 [14.7] years; 3846 [57.4%] male) with AKI-D with post-AKD kidney function follow-up and AKD stage data were enrolled. During a mean (SD) 1.2 (0.9) years of follow-up, the all-cause mortality rate was 28.3% (n = 1899), while the incidence rates of MACEs and ESKD were 11.1% (n = 746) and 16.7% (n = 1119), respectively. After adjusting for known covariates, both post-AKD kidney function and baseline kidney function, but not AKD severity, were independently associated with all-cause mortality, MACEs, ESKD, and readmission. Moreover, worse post-AKD kidney function correlated with progressive and significant increases in the risk of adverse outcomes. Conclusions and Relevance: In this cohort study of patients with AKI-D, more than one-quarter of patients died after 1.2 years of follow-up. Baseline and post-AKD kidney functions serve as important factors associated with the long-term prognosis of patients with AKI-D. Therefore, concerted efforts to understand the transition from post-AKD to chronic kidney disease are crucial.

Incidence, life expectancy and prognostic factors in cancer patients under prolonged mechanical ventilation: a nationwide analysis of 5,138 cases during 1998-2007.

INTRODUCTION: This study is aimed at determining the incidence, survival rate, life expectancy, quality-adjusted life expectancy (QALE) and prognostic factors in patients with cancer in different organ systems undergoing prolonged mechanical ventilation (PMV). METHODS: We used data from the National Health Insurance Research Database of Taiwan from 1998 to 2007 and linked it with the National Mortality Registry to ascertain mortality. Subjects who received PMV, defined as having undergone mechanical ventilation continuously for longer than 21 days, were enrolled. The incidence of cancer patients requiring PMV was calculated, with the exception of patients with multiple cancers. The life expectancies and QALE of patients with different types of cancer were estimated. Quality-of-life data were taken from a sample of 142 patients who received PMV. A multivariable proportional hazards model was constructed to assess the effect of different prognostic factors, including age, gender, type of cancer, metastasis, comorbidities and hospital levels. RESULTS: Among 9,011 cancer patients receiving mechanical ventilation for more than 7 days, 5,138 undergoing PMV had a median survival of 1.37 months (interquartile range [IQR], 0.50 to 4.57) and a 1-yr survival rate of 14.3% (95% confidence interval [CI], 13.3% to 15.3%). The incidence of PMV was 10.4 per 100 ICU admissions. Head and neck cancer patients seemed to survive the longest. The overall life expectancy was 1.21 years, with estimated QALE ranging from 0.17 to 0.37 quality-adjusted life years for patients with poor and partial cognition, respectively. Cancer of liver (hazard ratio [HR], 1.55; 95% CI, 1.34 to 1.78), lung (HR, 1.45; 95% CI, 1.30 to 1.41) and metastasis (HR, 1.53; 95% CI, 1.42 to 1.65) were found to predict shorter survival independently. CONCLUSIONS: Cancer patients requiring PMV had poor long-term outcomes. Palliative care should be considered early in these patients, especially when metastasis has occurred.

Investigating the utilization of radiological services by physician patients: a population-based cohort study in Taiwan.

BACKGROUND: Advances in radiology technology have contributed to a substantial increase in utilization of radiology services. Physicians, who are well educated in medical matters, would be expected to be knowledgeable about prudent or injudicious use of radiological services. The aim of this study was to evaluate differences in the utilization of radiology modalities among physician and non-physician patients. METHODS: This nationwide population-based cohort study was carried out using data obtained from the Taiwan National Insurance Database from 1997 to 2008. Physicians and comparison controls selected by propensity score matching were enrolled in the current study. The claims data of ambulatory care and inpatient discharge records were used to measure the utilization of various radiology modalities. Utilization rates of each modality were compared between physicians and non-physicians, and odds ratios of the utilization of each radiology modality were measured. Multiple logistic regression analysis was used to examine the predictors of X-ray, MRI, and interventional procedures utilization during the study period. RESULTS: The utilization of most radiologic services increased among physicians and the comparison group during the observation period. Compared to non-physicians, physicians had significantly higher utilization rates of computed tomography and magnetic resonance imaging (MRI) but lower utilization rates of X-rays, sonography, and interventional procedures. After adjusting for age, gender, major diseases, urbanicity, and residential regions, logistic regression analysis showed that, compared to non-physicians, the physicians used significantly more MRI (odds ratio [OR]: 2.19, 95% confidence interval [CI]: 1.68-2.84, P < 0.001) and significantly less X-rays and interventional procedures (OR: 0.85, 95% CI: 0.72-0.99, P = 0.04 for X-rays and OR: 0.67, 95% CI: 0.54-0.83, P < 0.001 for interventional procedures). Being a physician was a significant predictor of greater usage of MRI and of less usage of X-ray and interventional procedures. CONCLUSIONS: This study revealed different utilization patterns of X-rays, MRI, and interventional procedures between physician and non-physician patients, even after controlling for such factors as socioeconomic status and major diseases.
