Objective.To analyze the trend of prevalence and incidence rates for psoriatic arthritis (PsA) and psoriasis in Taiwan, and to determine the changes in medication patterns.Methods.Data were collected from the Taiwan National Health Insurance Research Database, which covered at least 95% of the population from 2000 to 2013. International Classification of Diseases, 9th edition (ICD-9) was used to identify PsA (ICD-9 696.0) and other psoriasis (ICD-9 696.1). Medications were identified by Anatomical Therapeutic Chemical Classification code. We calculated the annual age standardized prevalence and incidence rate of PsA and psoriasis in individuals aged ≥ 16 years from 2000 to 2013, and used the Poisson regression to test the trends by Wald chi-square statistic.Results.The prevalence (per 100,000 population) of psoriatic diseases between 2000 and 2013 increased from 11.12 to 37.75 for PsA, and from 179.2 to 281.5 for psoriasis. The incidence (per 100,000 person-yrs) increased from 3.64 to 6.91 in PsA, while there was no significant change in psoriasis. Prevalence and incidence in PsA were more rapidly increased than in psoriasis. Sex ratio (men to women) of PsA decreased from 2.0 to 1.5 in 2000 and 2013, respectively. There was an increase in the use of disease-modifying antirheumatic drugs (DMARD), especially biologics, which is significantly different from topical therapies.Conclusion.The prevalence and incidence rates of psoriatic disease, especially PsA, were increasing in Taiwan. The medication pattern showed an increase in DMARD and biologics, while use of topical therapies decreased.

Context: Diabetes is a risk factor for dementia, but the effects of diabetic severity on dementia are unclear. Objective: The purpose of this study was to investigate the association between the severity and progress of diabetes and the risk of dementia. Design and Setting: We conducted a 12-year population-based cohort study of new-onset diabetic patients from the Taiwan National Health Insurance Research Database. The diabetic severity was evaluated by the adapted Diabetes Complications Severity Index (aDCSI) from the prediabetic period to the end of follow-up. Cox proportional hazard regressions were used to calculate the hazard ratios (HRs) of the scores and change in the aDCSI. Participants: Participants were 431,178 new-onset diabetic patients who were older than 50 years and had to receive antidiabetic medications. Main Outcome: Dementia cases were identified by International Classification of Diseases, ninth revision, code (International Classification of Diseases, ninth revision, codes 290.0, 290.1, 290.2, 290.3, 290.4, 294.1, 331.0), and the date of the initial dementia diagnosis was used as the index date. Results: The scores and change in the aDCSI were associated with the risk of dementia when adjusting for patient factors, comorbidity, antidiabetic drugs, and drug adherence. At the end of the follow-up, the risks for dementia were 1.04, 1.40, 1.54, and 1.70 (P < .001 for trend) in patients with an aDCSI score of 1, 2, 3, and greater than 3, respectively. Compared with the mildly progressive patients, the adjusted HRs increased as the aDCSI increased (2 y HRs: 1.30, 1.53, and 1.97; final HRs: 2.38, 6.95, and 24.0 with the change in the aDCSI score per year: 0.51–1.00, 1.01–2.00, and > 2.00 vs < 0.50 with P < .001 for trend). Conclusions: The diabetic severity and progression reflected the risk of dementia, and the early change in the aDCSI could predict the risk of dementia in new-onset diabetic patients.

Objective: Because there are few population-based studies regarding the epidemiology of benign voice diseases, the present study used a nationwide population-based claims database (the National Health Insurance Research Database) to investigate the epidemiology of benign voice diseases among the general adult population in Taiwan. Methods: Study participants were retrieved for those patients who were 20 to 90 years old with a diagnosis of benign voice diseases that were defined by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes from 2006 to 2014. Patient visits were grouped into infectious (ICD-9-CM: 012.3, 032.3, 034.0, 090.5, 095.8,101, 464.0, 464.20, 464.21, 465.x, 476.0, 476.1) and noninfectious (ICD-9-CM: 306.1, 478.3x, 478.4, 478.5, 748.3, 784.4x) dysphonia groups. Results: Benign voice disorders have a prevalence of approximately 3.6% in Taiwan as of 2014. The year-to-year prevalence decreased gradually in the query period. Infectious dysphonia diagnoses were higher than noninfectious ones. Dysphonia caused by noninfectious diagnoses was most prevalent in the 60 to 79 years age group. Dysphonia caused by infectious diagnoses was highest in 20 to 39 years group. Noninfectious dysphonia diagnoses were more common in women. Conclusion: The prevalence of voice disorders among the adult population in Taiwan was 3.6% in 2014. Voice disorders are more common in women and occur primarily in the 20 to 39 years age group. Infectious dysphonia is more common than noninfectious dysphonia. The results may be underestimated due to limitation of the database. This is the first population-based epidemiology study of adult voice disorders.

ObjectivesTo examine the incidence rate and characteristics of paediatric abusive head trauma (PAHT) among children under age 5 years in Taiwan.MethodsThe International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) was used to identify broad and narrow definitions of children aged under 5 years with PAHT from 2006 to 2015 in Taiwan using a representative national insurance research database. Medical resource utilisation was also analysed. Incidence rates per 100 000 person-years were calculated and presented with 95% CI. Joinpoint regression analysis was used to detect the changes in trends and calculate the annual percentage change in PAHT incidence over time.ResultsFrom 2006 to 2015, 479 (narrow definition) and 538 (broad definition) PAHT cases were identified. Incidence rates of PAHT by narrow and broad definitions among children under 1 year of age (18.7/100 000 and 20.0/100 000) were nearly 10-fold or 20-fold higher than for children aged 1–2 (1.7/100 000 and 2.1/100 000) and 3–5 (0.9/100 000 and 1.2/100 000) years. The PAHT incidence significantly increased since 2012, with trends varying by age and gender. Our results suggest that over 40% of the children with PAHT experienced serious injury and nearly 13% were fatal cases. For 87% (n=57) of fatal cases, this was their first ever hospitalisation. The number of fatal cases among infants was fourfold higher than that of children aged 1–5 years.ConclusionsThis study provides a robust national estimate of PAHT and identifies infants as the most vulnerable group for PAHT in Taiwan. Education to enhance healthcare profession’s sensitivity and competence for the early identification and diagnosis of PAHT is critical.

Bladder Antimuscarinics

AbstractThe association between bladder antimuscarinic use and dementia development is unclear. We used data from the Taiwan National Health Insurance Research Database to determine the association between the exposure dose and duration of bladder antimuscarinics and the subsequent dementia risk. We enrolled participants aged 55 years or more and defined a dementia cohort (International Classification of Diseases, Ninth Revision, Clinical Modification codes 290, 294.1, and 331.0). We used a propensity score matching method, and randomly enrolled two controls without dementia. We evaluated dementia risk with respect to the exposure dose and duration of treatment with seven bladder antimuscarinics (oxybutynin, propiverine, tolterodine, solifenacin, trospium, darifenacin, and fesoterodine) used for at least 1 year before the index date, after adjusting for age, sex, comorbidities, and medications. The dementia risk was 2.46-fold (95% confidence interval: 2.22–2.73) higher in Taiwanese patients who used bladder antimuscarinics for ≥ 1 year than in those who were not exposed to this treatment. The risk proportionally increased with increasing doses of antimuscarinics for less than 4 years. Taiwanese patients aged 55 years or more on bladder antimuscarinics exhibited a higher risk of dementia. Additional studies in other countries are required to determine whether this result is valid worldwide.

Oral Verapamil

Abstract Objective: The mechanism of the beneficial effect of calcium-channel blockers (CCBs), especially verapamil, on the development of type 2 diabetes mellitus (T2DM) has been described. This study compared the incidence of T2DM in adults prescribed oral verapamil and propensity score–matched adults prescribed other oral CCBs. Methods: This retrospective population-based cohort study used Taiwan’s National Health Insurance Research Database from 2000 to 2011. T2DM was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification. Results: During follow-up periods of 41,958 and 42,118 person-years, 269 of 4930 patients in the verapamil cohort and 340 of 4930 patients in the matched cohort, respectively, developed T2DM. The incidence rates were 6.41 and 8.07 per 1000 population per year among verapamil and other CCB users, respectively. The adjusted hazard ratio (HR) for T2DM associated with use of verapamil (vs. other CCBs) was 0.80 [95% confidence interval (CI), 0.68 to 0.94; P = 0.006]. After exclusion of patients followed for <180 days or <365 days (to avoid bias derived from delayed diagnosis), adjusted HRs remained significant [0.79 (95% CI, 0.67 to 0.93; P = 0.005) and 0.77 (95% CI, 0.65 to 0.91; P = 0.002), respectively]. Only the interaction term for age was significant (P = 0.009). Verapamil had a more prominent effect on patients aged older than 65 years (P < 0.001). Conclusions: In patients with no known history of diabetes mellitus, oral verapamil use was associated with a decreased incidence of T2DM compared with other CCBs.

Background:Chlamydia pneumoniae (CPn) is a common community-acquired pneumonia. In the literature, CPn infection is demonstrated to exhibit an association with Alzheimer dementia (AD). We executed the present nationwide, population-based research with the goal of probing the association of CPn infection and antibiotic therapy with AD risk.Methods: We conducted a cohort study using a database extracted from Taiwan's National Health Insurance Research Database (NHIRD). All medical conditions for each enrolled individuals were categorized using the International Classification of Diseases, ninth Revision classifications. Hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between CPn pneumonia-associated hospitalizations and AD were estimated using Fine and Gray's survival analysis and adjusted for comorbidities. The effects of the antibiotics on the HRs for AD in the patients with CPn pneumonia-associated hospitalization were also analyzed.Results: Our analyses included 6,628 individuals, including 1,657 CPn-infected patients, as well as 4,971 controls matched by age, index date, and sex (1:3). In this study, patients hospitalized for CPn pneumonia exhibited a significantly higher AD risk (adjusted HR = 1.599, 95% CI = 1.284–1.971, p < 0.001). We also noted an association of macrolide use (≥15 days) and fluoroquinolone use (≥15 days) with decreased AD risk.Conclusions: We determined CPn pneumonia to be associated with a relatively high AD risk. The result in this study confirmed the findings from previous literatures, by using a large, nationwide, population-based database. Appropriate macrolide and fluoroquinolone treatment may attenuate this risk.

Background: Large-scale and population-based studies of heart failure (HF) incidence and prevalence are scarce in China. The study sought to estimate the prevalence, incidence, and cost of HF in China. Methods: We conducted a population-based study using records of 50.0 million individuals ≥25 years old from the national urban employee basic medical insurance from 6 provinces in China in 2017. Incident cases were individuals with a diagnosis of HF (International Classification of Diseases code, and text of diagnosis) in 2017 with a 4-year disease-free period (2013–2016). We calculated standardized rates by applying age standardization to the 2010 Chinese census population. Results: The age-standardized prevalence and incidence were 1.10% (1.10% among men and women) and 275 per 100 000 person-years (287 among men and 261 among women), respectively, accounting for 12.1 million patients with HF and 3.0 million patients with incident HF ≥25 years old. Both prevalence and incidence increased with increasing age (0.57%, 3.86%, and 7.55% for prevalence and 158, 892, and 1655 per 100 000 person-years for incidence among persons who were 25–64, 65–79, and ≥80 years of age, respectively). The inpatient mean cost per-capita was $4406.8 and the proportion with ≥3 hospitalizations among those hospitalized was 40.5%. The outpatient mean cost per-capita was $892.3. Conclusions: HF has placed a considerable burden on health systems in China, and strategies aimed at the prevention and treatment of HF are needed.

Objective To investigate readmissions among adult inpatients who underwent uvulopalatopharyngoplasty (UPPP) in Taiwan. Design Population-based survey. Setting Retrospective study with the National Health Insurance Database. Methods All cases of inpatient adult UPPP (age >20 years) from 1997 to 2012 were identified through International Classification of Diseases, Ninth Revision, Clinical Modification. Factors associated with readmission within 30 days after surgery were analyzed. Results A total of 38,839 adults with UPPP were identified (mean age, 39.3 years; men, 73.7%). The incidence of UPPP was 14.6 per 100 000 adults, which increased from 1997 to 2012 (6.7 to 16.7 per 100,000, Ptrend < .001). The rates of readmission for any reason, readmission for bleeding, reoperation for bleeding, and 30-day mortality were 4.2%, 1.7%, 1.0%, and 0.14%, respectively. Young age increased the risk of reoperation for bleeding, and old age increased the risk of readmission for any reason and mortality. Men had an increased risk of readmission and reoperation. Hypertension was associated with an increased risk of readmission for any reason (odds ratio [OR], 1.29; 95% CI, 1.10-1.51), bleeding-related readmission (OR, 1.89; 95% CI, 1.52-2.36), and reoperation (OR, 2.47; 95% CI, 1.84-3.30). Concurrent hypopharyngeal surgery was associated with an increased risk of readmission for any reason (OR, 1.34; 95% CI, 1.07-1.66) and bleeding-related readmission (OR, 1.69; 95% CI, 1.25-2.27). Finally, the use of steroids was associated with an increased risk of bleeding-related readmission and reoperation. Conclusions The incidence of adult UPPP increased from 1997 to 2012 in Taiwan. Age, sex, comorbidity, concurrent hypopharyngeal surgery, and drug administration were associated with readmission after inpatient UPPP.

The prevalence and incidence of doctor-diagnosed Dupuytren’s disease in the general population is unknown. From the healthcare register for Skåne region (population 1.3 million) in southern Sweden, we identified all residents aged ⩾20 years (on 31 December 2013), who 1998 to 2013 had consulted a doctor and received the diagnosis Dupuytren’s disease (International Classification of Diseases 10th Revision code M720). During the 16 years, 7207 current residents (72% men) had been diagnosed with Dupuytren’s disease; the prevalence among men was 1.35% and among women 0.5%. Of all people diagnosed, 56% had received treatment (87% fasciectomy). In 2013, the incidence of first-time doctor-diagnosed Dupuytren’s disease among men was 14 and among women five per 10,000. The annual incidence among men aged ⩾50 years was 27 per 10,000. Clinically important Dupuytren’s disease is common in the general population. Level of evidence: III

Subarachnoid hemorrhage (SAH) is a critical illness that may result in patient mortality or morbidity. In this study, we investigated the outcomes of patients treated in medical center and nonmedical center hospitals and the relationship between such outcomes and hospital and surgeon volume. Patient data were abstracted from the National Health Insurance Research Database of Taiwan in the Longitudinal Health Insurance Database 2000, which contains all claims data of 1 million beneficiaries randomly selected in 2000. The International Classification of Diseases, Ninth Revision, subarachnoid hemorrhage (430) was used for the inclusion criteria. We identified 355 patients between 11 and 87 years of age who had subarachnoid hemorrhage. Among them, 32.4% (115/355) were men. The median Charlson comorbidity index (CCI) score was 1.3 (SD ± 0.6). Unadjusted logistic regression analysis demonstrated that low mortality was associated with high hospital volume (OR = 3.21; 95% CI: 1.18–8.77). In this study, we found no statistical significances of mortality, LOS, and total charges between medical centers and nonmedical center hospitals. Patient mortality was associated with hospital volume. Nonmedical center hospitals could achieve resource use and outcomes similar to those of medical centers with sufficient volume.
