Abstract
PURPOSE This study evaluated treatment patterns and clinical outcomes among patients with metastatic triple-negative breast cancer (mTNBC) in real-world clinical settings in Japan. METHODS The treatment patterns, time to next treatment or death (TTNTD), time to treatment discontinuation, adverse events of interest, and medical costs of treating patients with mTNBC in first-, second-, and third-line settings were investigated using data of patients meeting the inclusion criteria between January 2017 and March 2022 in a Japanese medical claims database. The treatment regimens for mTNBC were defined according to the Japanese Breast Cancer Society Clinical Practice Guidelines. RESULTS In this study, 2236 patients with mTNBC (median age 66.0 years; 99.8% female) were included in the first-line cohort. Of these, 46.6% and 20.8% were included in the second- and third-line cohorts, respectively. The two most frequently used treatments were capecitabine (19.1%) and S-1 (tegafur-gimeracil-oteracil) (14.5%) in the first-line cohort, eribulin (18.3%) and bevacizumab/paclitaxel (14.4%) in the second-line cohort, and eribulin (19.4%) and bevacizumab/paclitaxel (17.5%) in the third-line cohort. The TTNTD shortened as the line of therapy progressed (median 8.0, 6.5, and 5.2 months for the first-, second-, and third-line treatments, respectively). Nausea/vomiting and neutropenia/leukopenia occurred in 62.8% and 18.3% of all patients, respectively. The medical total costs per day were 6.7, 10.2, and 12.9 thousand yen during the first-/second-/third-line treatments, respectively. CONCLUSION This study provides insight into current treatment patterns for mTNBC in Japan. The cost-benefit balance worsens with later-line treatment and a high unmet need for mTNBC drug treatment remains.

Abstract
AIMS The use of large medical or healthcare claims databases is very useful for population-based studies on the burden of heart failure (HF). Clinical characteristics and management of HF patients differ according to categories of left ventricular ejection fraction (LVEF), but this information is often missing in such databases. We aimed to develop and validate algorithms to identify LVEF in healthcare databases where the information is lacking. METHODS AND RESULTS Algorithms were built by machine learning with a random forest approach. Algorithms were trained and reinforced using the French national claims database [Système National des Données de Santé (SNDS)] and a French HF registry. Variables were age, gender, and comorbidities, which could be identified by medico-administrative code-based proxies, Anatomical Therapeutic Chemical codes for drug delivery, International Classification of Diseases (Tenth Revision) coding for hospitalizations, and administrative codes for any other type of reimbursed care. The algorithms were validated by cross-validation and against a subset of the SNDS that includes LVEF information. The areas under the receiver operating characteristic curve were 0.84 for the algorithm identifying LVEF ≤ 40% and 0.79 for the algorithms identifying LVEF < 50% and ≥50%. For LVEF ≤ 40%, the reinforced algorithm identified 50% of patients in the validation dataset with a positive predictive value of 0.88 and a specificity of 0.96. The most important predictive variables were delivery of HF medication, sex, age, hospitalization, and testing for natriuretic peptides with different orders of positive or negative importance according to the LVEF category. CONCLUSIONS The algorithms identify reduced or preserved LVEF in HF patients within a nationwide healthcare claims database with high positive predictive value and low rates of false positives.

Abstract
INTRODUCTION Pulmonary hypertension (PH) is often complicated by chronic lung diseases (CLDs) such as chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Differentiating between PH associated with CLD (group 3 PH) and pulmonary arterial hypertension (PAH) in CLD is often difficult and reporting on the efficacy of PAH-specific therapies is inconsistent as a result of the lack of understanding of the heterogeneity of patients with PH. METHODS A retrospective observational cohort study was conducted to understand the baseline characteristics, comorbidities, and treatment profiles of patients with PH in CLD in a real-world setting using a large-scale claims database (Medical Data Vision). Administrative and clinical data for patients admitted to acute-care hospitals in Japan between April 2008 and January 2021 were analyzed. RESULTS A total of 115,921 patients with CLD (109,578 with COPD and 6343 with ILD, of whom 569 and 176 had PH, respectively) were analyzed. This study found lower PH diagnosis rates among patients with COPD and patients with ILD than in previous studies. The majority of PH with CLD patients were elderly (mean age 75.7 years) and male (80.81%). Among patients with CLD prescribed PAH-specific therapies (105 patients with COPD; 64 patients with ILD), most received these as monotherapy (COPD, 84.76%; ILD, 75.56%); the most common were phosphodiesterase 5 inhibitors (COPD, 42.70%; ILD, 18.37%), prostacyclins (oral; COPD, 48.31%; ILD, 24.49%), and endothelin receptor antagonists (ERA) (COPD, 8.99%; ILD, 18.37%). Comorbidities (e.g., pulmonary, cardiac, kidney), home oxygen therapy (HOT), and echocardiography (ECHO) were factors associated with the diagnosis of PH. CONCLUSION This is the first study using an administrative database that provides real-world data on patients with PH in CLD in Japan. Our results indicate that PH may be misdiagnosed or underdiagnosed in Japan which may lead to suboptimal treatment for patients, and supports the need for further evidence to guide appropriate treatment.

Abstract
BACKGROUND Myocardial infarction (MI), stroke, peripheral arterial disease (PAD), heart failure (HF) and chronic kidney disease (CKD) are common cardiovascular renal diseases (CVRD) manifestations for type 2 diabetes. The objective was to estimate the incidence of the first occurring CVRD manifestation and cumulative hospitalization costs of each CVRD manifestation for type 2 diabetes without CVRD history. METHODS A cohort study of all type 2 diabetes free of CVRD as of January 1st 2014, was identified and followed-up for 5 years within the French SNDS nationwide claims database. The cumulative incidence of the first occurring CVRD manifestation was estimated using the cumulative incidence function, with death as a competing risk. Cumulative hospitalization costs of each CVRD manifestations were estimated from the perspective of all payers. RESULTS From 2,079,089 type 2 diabetes without cancer or transplantation, 76.5% were free of CVRD at baseline with a mean age of 65 years, 52% of women and 7% with microvascular complications history. The cumulative incidence of a first CVRD manifestation was 15.3% after 5 years of follow-up with a constant linear increase over time for all CVRD manifestations: The most frequent was CKD representing 40.6% of first occurred CVRD manifestation, followed by HF (23.0%), then PAD (13.5%), stroke (13.2%) and MI (9.7%). HF and CKD together reached about one patient out of ten after 5 years and represented 63.6% of first CVRD manifestations. The 5-year global cost of all CVRD hospitalizations was 3.9 billion euros (B€), i.e. 2,450€ per patient of the whole cohort, with an exponential increase over time for each specific CVRD manifestation. The costliest was CKD (2.0 B€), followed by HF (1.2 B€), then PAD (0.7 B€), stroke (0.6 B€) and MI (0.3 B€). CONCLUSIONS/INTERPRETATION While MI, stroke and PAD remain classic major risks of complications for CVRD-free type 2 diabetes, HF and CKD nowadays represent individually a higher risk and cost than each of these classic manifestations, and jointly represents a risk and a cost twice as high as these three classic manifestations all together. This should encourage the development of specific HF and CKD preventive strategies.

Abstract
BACKGROUND We aimed to evaluate the validity of self-administered questionnaire surveys and face-to-face interview surveys for the detection of Helicobacter pylori eradication therapy. METHODS Participants were a cohort, aged 40-74 years, living in three different locations of Japan, who took part in the baseline survey (2011-2012) of the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT). Five years after the baseline survey, a questionnaire and interview survey were independently conducted to determine the history of Helicobacter pylori eradication treatment over the 5-year period. Prescription of Helicobacter pylori eradication medications in national insurance claims data from the baseline survey to the 5-year survey was used as a reference standard. RESULTS In total, 15,760 questionnaire surveys and 8,006 interview surveys were included in the analysis. There were 3,471 respondents to the questionnaire and 2,398 respondents to the interview who reported having received Helicobacter pylori eradication treatment within the past five years. Comparison of the questionnaire survey to national insurance claims data showed a sensitivity of 95.1% (2213/2328), specificity of 90.6% (12174/13432), positive predictive value of 63.8% (2213/3471), negative predictive value of 99.1% (12174/12289), and Cohen's Kappa value of 0.71. Respective values of the interview survey were 94.4% (1694/1795), 88.7% (5507/6211), 70.6% (1694/2398), 98.2% (5507/5608), and 0.74. CONCLUSION Both the questionnaire and the interview showed high sensitivity, high specificity, and good agreement with the insurance claim prescriptions data. Some participants may have received eradication treatment without going through the public insurance claim database, resulting in a low positive predictive value.

Abstract
BACKGROUND Biologics are increasingly being used in patients with severe uncontrolled asthma. However, the trends in their use for treating severe asthma in Japan remain unclear. METHODS The number of patients with asthma prescribed omalizumab or mepolizumab between April 2017 and March 2018 was estimated according to sex, age, and geographical region using data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. RESULTS Overall, 5,014, 3,449 and 7,977 patients were prescribed omalizumab, mepolizumab, or either combination, respectively. The total number of patients prescribed biologics displayed a bimodal distribution with peaks in their early teens and seventies. Biologics were most commonly used by male and female patients in their seventies. Prescription was 1.24 times higher in males than in females up to the teenage years, whereas it was 1.95 times higher in females than in males from their twenties onwards. Omalizumab was prescribed 1.45 times more frequently than mepolizumab, especially in pediatric patients, and was prescribed 1.96 times more often to female patients than to male patients. Regional differences were observed in the proportion of patients prescribed biologics. Correlation analysis suggested a weak relationship (r = 0.3226, p = 0.0270) between the proportion of patients prescribed biologics and board-certified allergists according to the geographic region. CONCLUSIONS In Japan, biologics are prescribed more often to older patients with severe asthma compared to those in other countries. Thus, eliminating the regional disparities in asthma treatment by specialists is necessary to provide appropriate medical care to patients with severe asthma.

Abstract
PURPOSE Chemotherapy-induced peripheral neuropathy (CIPN) has been reported to reduce patients' quality of life and impair cancer treatment by causing anticancer drug withdrawal or interruption. However, there are currently no effective methods for the prevention of CIPN. Renin-angiotensin-aldosterone system (RAAS) inhibitors may be associated with a reduced risk of developing oxaliplatin-induced peripheral neuropathy, and it would be valuable to examine whether they have the same effect on CIPN caused by other anticancer drugs. Our study explored the potential preventive effects of RAAS inhibitors on preventing paclitaxel-induced peripheral neuropathy (PIPN). METHODS An exploratory cohort study was conducted using commercially available administrative claims data on lung cancer patients treated with paclitaxel-based chemotherapy. Cumulative paclitaxel doses, RAAS inhibitor prescriptions, and incidences of PIPN were identified using patient medical records. Fine-Gray analyses with death as a competing risk were performed. A propensity score approach was applied to address the problem of confounding. RESULTS Patients with lung cancer who received paclitaxel-based chemotherapy were classified into users of RAAS inhibitor (n = 1320) and non-users of RAAS inhibitor (n = 4566). The doses of RAAS inhibitors in our study were similar to those commonly used to treat hypertension. The PIPN incidence was significantly lower in users of RAAS inhibitor than in the non-users of RAAS inhibitor (sub-distribution hazard ratio, 0.842; 95% confidence interval, 0.762-0.929). The result was consistent in various sensitivity analyses and important subgroup analyses. CONCLUSIONS RAAS inhibitors at doses commonly used for hypertension were associated with a reduced incidence of PIPN in patients with lung cancer.

Abstract
INTRODUCTION Patients with psoriasis (PsO) are at increased risk of herpes zoster (HZ), but recent data on the incidence of HZ among patients with PsO and the impact of HZ on healthcare resource use (HRU) and costs for patients with PsO have not been described. METHODS This retrospective, longitudinal, cohort study estimated HZ incidence in cohorts of adults with vs without PsO (PsO + vs PsO-) and HRU and costs among those with PsO, with vs without HZ (PsO + /HZ + vs PsO + /HZ-) using Optum's de-identified Clinformatics Data Mart Database during 2015-2020. Patients with psoriatic arthritis were excluded from all four cohorts. Comparisons between cohorts used generalized linear models to adjust outcomes based on various baseline characteristics. RESULTS The incidence rate of HZ was significantly higher in the PsO + (n = 144,115) vs PsO- (n = 23,837,237) cohorts at 11.35 vs 7.67 per 1000 patient-years; adjusted incidence rate ratio (aIRR): 1.21, 95% confidence interval (CI): 1.16-1.25. HRU (outpatient, emergency department, and inpatient) was significantly higher in the PsO + /HZ + (n = 1859) vs PsO + /HZ- (n = 78,664) cohorts during 1 month and 3 months after HZ diagnosis (e.g., outpatient visits during month: 2.83 vs 1.30 per patient; aIRR: 1.96; 95% CI 1.86-2.06). Mean all-cause costs were also significantly higher in the PsO + /HZ + vs PsO + /HZ- cohort during both month ($5020 vs $2715 per patient; adjusted cost difference: $1390; 95% CI $842-$1964) and 3 months ($12,305 vs $8256; adjusted cost difference: $1422; 95% CI $280-$2889) after HZ diagnosis. CONCLUSION These findings show the increased incidence of HZ among patients with PsO and the clinical and economic burdens of HZ in this population. Considering the high prevalence of PsO, insights into the impact of HZ in these patients provide valuable evidence to inform clinical decision-making.

Abstract
INTRODUCTION Prior research has demonstrated that early treatment with high-efficacy disease-modifying therapies (DMTs), including ocrelizumab (OCR), can reduce relapses and delay disease progression among persons with multiple sclerosis (pwMS) compared with escalation from low-/moderate-efficacy DMTs. However, there is a lack of research examining the impact of early use of OCR on real-world clinical and economic outcomes. This study aimed to evaluate differences in events often associated with a relapse (EOAR) as well as non-DMT healthcare resource use (HCRU) and costs among pwMS who received OCR as a first-line treatment compared with later-line treatment after diagnosis. METHODS Newly diagnosed adult pwMS were selected from deidentified Optum Market Clarity claims data (study period: January 1, 2015-June 30, 2021). All pwMS were required to have initiated OCR after diagnosis and have 12 months of continuous eligibility prior to diagnosis. The index date was the date of initiation of the first-line DMT after diagnosis. pwMS who initiated OCR as first-line (1L OCR cohort) or a second- or later-line treatment (2L + OCR cohort) were matched 1:1 based on length of continuous eligibility after the first-line DMT and weighted using stabilized inverse probability of treatment. In the follow-up period, differences in outcomes, including annualized EOAR, non-DMT HCRU and costs, were evaluated for pwMS in the 1L vs. 2L + OCR cohorts. RESULTS The sample included 748 pwMS. During the follow-up period, pwMS in the 1L OCR cohort had a significantly lower annual rate of EOAR compared with pwMS in the 2L + OCR cohort (0.37 vs. 0.56; difference: 0.20 [95% CI 0.08, 0.32]). pwMS in the 1L OCR cohort had a significantly lower probability of any hospitalization within 1 year, fewer non-DMT outpatient visits and lower all-cause and MS-related, non-DMT costs compared with pwMS in the 2L + OCR cohort. CONCLUSIONS First-line initiation OCR was associated with improvements in clinical and non-DMT economic outcomes compared with later-line initiation of OCR, suggesting that early initiation may benefit both patients and the healthcare system.

Abstract
BACKGROUND Sickle cell disease (SCD) is a major public health concern in sub-Saharan Africa, accounting for nearly 75% of the global disease burden. The current analysis evaluated patient characteristics, treatment patterns, healthcare resource utilization (HCRU) and associated costs in patients with SCD based on a Private Medical Insurance Database in Ghana. METHODS This retrospective longitudinal cohort study was conducted using an e-claims database from Ghana (01 January 2015 to 31 March 2021). Patients were stratified by age (0 month to < 2 years, ≥ 2 years to ˂6 years, ≥ 6 years to < 12 years, ≥ 12 years to < 16 years; ≥16 years), vaso-occlusive crisis (VOC) (< 1, ≥ 1 to < 3, and ≥ 3 per year), and continuous enrolment. Study outcomes related to patient characteristics, comorbidities, treatment pattern, HCRU were evaluated for pre- and post-index period (index period was between July 2015 to March 2020). Descriptive analysis was used to analyse different study variables. RESULTS The study included 2,863 patients (mean age: 20.1 years; Min age: 0; Max age: 83; females 56.1%). Overall, 52.2% (n = 1,495) of SCD patients were ≥ 16 years and 17.0% (n = 486) were in the ≥ 2 to ˂6-years age group. The majority of patients aged ≥ 16 years (62.5%) in the database did not have reported VOC episodes, 35.9% of patients had 1 to 3 VOCs per year and 1.5% had ≥ 3 VOCs per year during the follow-up period. Consultation-based prevalence of SCD was 0.5% [95% confidence interval (CI): 0-1.3%] - 1.4% [CI: 0.6-2.2%]. Malaria, upper respiratory tract infection (URTI) and sepsis were the common complications of SCD. Analgesics were the most frequently prescribed medications followed by anti-infectives, hematinics, and antimalarials. Hydroxyurea, a routine standard of care for SCD was under-utilized. SCD patients had median cost incurred for consultation/hospital services of $11.3 (Interquartile range [IQR] $6.2 - $27.2). For patients with VOC, maximum median cost was incurred for medications ($10.9 [IQR $5.0-$32.6]). Overall median healthcare cost was highest for individuals with ≥ 3 VOCs per year during the follow-up period ($166.8 [IQR $70.3-$223.5]). CONCLUSION In this retrospective private insurance claims database analysis, SCD imposes a significant healthcare burden, especially in patients with VOC. There is a need for reimbursed treatment options that could reduce the long-term burden associated with SCD and VOC.

Abstract
INTRODUCTION Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a rare progressive or relapsing inflammatory disease. Intravenous immunoglobulin (IVIG) is recommended as a first-line therapy. The aim of this study was to describe real-world treatment patterns and outcomes of patients with CIDP in the Define initiating IVIG treatment. METHODS This cohort study used health insurance claims data from the Merative MarketScan Research Databases (2008-2018). Adult patients (≥ 18 years old) with CIDP without prior immunoglobulin treatment were identified using International Statistical Classification of Diseases and Related Health Problems (ICD) codes, and patients subsequently initiating IVIG were included in the analysis. Real-world IVIG treatment patterns and treatment and safety outcomes (assessed via ICD codes) were described. RESULTS In total, 3975 patients (median age 58 years) with CIDP who initiated IVIG were identified. After the initial IVIG loading period, patients received IVIG at a median dosing interval of 21 days (quartile [Q]1, Q3: 7, 28), and continued treatment for a median of 129 days (Q1, Q3: 85, 271). After the 2-year follow-up period, 55% of patients had discontinued all IVIG treatment; more than one-half of these discontinuations occurred within 4 months. Diagnoses of impaired functional status were evident in more than 30% of patients at baseline, but at lower rates during follow-up. Rates of new-onset safety outcomes after IVIG treatment were low. CONCLUSION This real-world analysis of IVIG treatment patterns and treatment and safety outcomes of patients with CIDP who initiated IVIG highlights the unmet need for improved long-term management. Further research is needed to evaluate the use of functional status measures as endpoints for immunoglobulin treatment effectiveness.

Abstract
INTRODUCTION Intravenous immunoglobulin (IVIG) is recommended as first-line therapy for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), an immune-mediated neuropathy. The clinical profile of patients with CIDP newly initiating IVIG is poorly characterized. This claims-based cohort study describes characteristics of US patients with CIDP initiating IVIG treatment. METHODS Adult immunoglobulin (IG)-naïve patients with CIDP diagnosed between 2008 and 2018 and a subgroup of patients subsequently initiating IVIG were identified in the Merative MarketScan Research Databases. Demographics, clinical characteristics, and diagnostic procedures were described for patients initiating IVIG. RESULTS Of 32,090 patients with CIDP identified, 3975 (mean age 57 years) subsequently initiated IVIG. In the 6 months prior to IVIG initiation, diagnoses of comorbidities including neuropathy (75%), hypertension (62%), and diabetes (33%) were frequent, as were CIDP features/symptoms/markers of functional status including chronic pain (80%), difficulty walking (30%), and weakness (30%). CIDP-related laboratory/diagnostic procedures were performed in approximately 20- > 40% of patients in the 3 months prior to IVIG initiation (63.7% underwent electrodiagnostic/nerve conduction testing in the 6 months prior to IVIG initiation). Patient characteristics by initial IVIG product differed only in IVIG initiation year, US geographic region, and insurance type. Comorbidities, CIDP severity or functional status markers, and other clinical variables were generally well balanced across initial IVIG product groups. CONCLUSION A heavy burden of symptoms, comorbidities, and diagnostic testing exists in patients with CIDP initiating IVIG. Characteristics of patients with CIDP initiating different IVIG products are well balanced, suggesting an absence of clinical or demographic determinants underlying IVIG selection.

Abstract
BACKGROUND Medications influencing the risk of fall-related injuries (FRIs) in older adults have been inconsistent in previous guidelines. This study employed case-control design to assess the association between FRIs and medications, and an additional case-crossover design was conducted to examine the consistency of the associations and the transient effects of the medications on FRIs. METHODS This study was conducted using a national claims database (2002-2015) in Korea. Older adults (≥ 65 years) who had their first FRI between 2007 and 2015 were matched with non-cases in 1:2 ratio. Drug exposure was examined for 60 days prior to the date of the first FRI (index date) in the case-control design. The hazard period (1-60 days) and two control periods (121-180 and 181-240 days prior to the index date) were investigated in the case-crossover design. The risk of FRIs with 32 medications was examined using conditional logistic regression after adjusting for other medications that were significant in the univariate analysis. In the case-crossover study, the same conditional model was applied. RESULTS In the case-control design, the five medications associated with the highest risk of FRIs were muscle relaxants (adjusted odd ratio(AOR) = 1.35, 95% confidence interval (CI) = 1.31-1.39), anti-Parkinson agents (AOR = 1.30, 95%CI = 1.19-1.40), opioids (AOR = 1.23, 95%CI = 1.19-1.27), antiepileptics (AOR = 1.19, 95%CI = 1.12-1.26), and antipsychotics (AOR = 1.16, 95%CI = 1.06-1.27). In the case-crossover design, the five medications associated with the highest risk of FRIs were angiotensin II antagonists (AOR = 1.87, 95%CI = 1.77-1.97), antipsychotics (AOR = 1.63, 95%CI = 1.42-1.83), anti-Parkinson agents (AOR = 1.58, 95%CI = 1.32-1.85), muscle relaxants (AOR = 1.42, 95%CI = 1.35-1.48), and opioids (AOR = 1.35, 95%CI = 1.30-1.39). CONCLUSIONS Anti-Parkinson agents, opioids, antiepileptics, antipsychotics, antidepressants, hypnotics and sedatives, anxiolytics, muscle relaxants, and NSAIDs/antirheumatic agents increased the risk of FRIs in both designs among older adults. Medications with a significant risk only in the case-crossover analysis, such as antithrombotic agents, calcium channel blockers, angiotensin II antagonists, lipid modifying agents, and benign prostatic hypertrophy agents, may have transient effects on FRIs at the time of initiation. Corticosteroids, which were only associated with risk of FRIs in the case-control analysis, had more of cumulative than transient effects on FRIs.

Abstract
INTRODUCTION Essential tremor (ET) is the most common tremor disorder, estimated to affect 7 million individuals in the USA. There is little empirical evidence on comorbidities among this population beyond higher prevalence of brain-related and stress-related disorders. This study aims to examine differences in the prevalence of the 31 Elixhauser comorbidities among ET patients compared to statistically similar control patients. METHODS An extract from Optum's de-identified Clinformatics® Data Mart Database (CDM) from 2018 to 2019 of adults aged 40-80 years with at least one claim with an ET diagnosis was propensity score matched to controls. Logistic regression was used to generate doubly robust adjusted odds ratios for each of the 31 Elixhauser comorbidities. RESULTS In these analyses, ET patients had significantly greater adjusted odds of depression, alcohol abuse, and other neurological disorders, as well as chronic pulmonary disease, renal failure, hyperthyroidism, and cardiac arrhythmias relative to controls. They also had lower odds of uncomplicated diabetes, congestive heart failure, metastatic cancer, paralysis, peripheral vascular disease, and fluid and electrolyte disorders. CONCLUSION A number of recent studies, including our own, suggest that psychiatric, neurologic, and stress-related disorders may be more prevalent among ET patients than controls. Additional differences in the prevalence of a range of medical comorbidities have also been variably reported across studies, suggesting that some combination of these might be more prevalent. Further studies would be of value in sorting through these associations.

Abstract
BACKGROUND There is limited consensus regarding the optimal treatment of insomnia. The recent introduction of orexin receptor antagonists (ORA) has increased the available treatment options. However, the prescribing patterns of hypnotics in Japan have not been comprehensively assessed. We performed analyses of a claims database to investigate the real-world use of hypnotics for treating insomnia in Japan. METHODS Data were retrieved for outpatients (aged ≥ 20 to < 75 years old) prescribed ≥ 1 hypnotic for a diagnosis of insomnia between April 1st, 2009 and March 31st, 2020, with ≥ 12 months of continuous enrolment in the JMDC Claims Database. Patients were classified as new or long-term users of hypnotics. Long-term use was defined as prescription of the same mechanism of action (MOA) for ≥ 180 days. We analyzed the trends (2010-2019) and patterns (2018-2019) in hypnotics prescriptions. RESULTS We analyzed data for 130,177 new and 91,215 long-term users (2010-2019). Most new users were prescribed one MOA per year (97.1%-97.9%). In 2010, GABAA-receptor agonists (benzodiazepines [BZD] or z-drugs) were prescribed to 94.0% of new users. Prescriptions for BZD declined from 54.8% of patients in 2010 to 30.5% in 2019, whereas z-drug prescriptions remained stable (~ 40%). Prescriptions for melatonin receptor agonist increased slightly (3.2% to 6.3%). Prescriptions for ORA increased over this time from 0% to 20.2%. Prescriptions for BZD alone among long-term users decreased steadily from 68.3% in 2010 to 49.7% in 2019. Prescriptions for ORA were lower among long-term users (0% in 2010, 4.3% in 2019) relative to new users. Using data from 2018-2019, multiple (≥ 2) MOAs were prescribed to a higher proportion of long-term (18.2%) than new (2.8%) users. The distribution of MOAs according to psychiatric comorbidities, segmented by age or sex, revealed higher proportions of BZD prescriptions in elderly (new and long-term users) and male (new users) patients in all comorbidity segments. CONCLUSION Prescriptions for hypnotics among new and long-term users in Japan showed distinct patterns and trends. Further understanding of the treatment options for insomnia with accumulating evidence for the risk-benefit balance might be beneficial for physicians prescribing hypnotics in real-world settings.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is associated with significant morbidity and economic burden. This study aimed to compare baseline characteristics and patterns of anti-inflammatory drug use and disease-modifying anti-rheumatic drug (DMARD) use among patients with RA in Southern Italy versus the United States. METHOD Using Caserta Local Health Unit (Italy) and Optum's de-identified Clinformatics® Data Mart (United States) claims databases, patients with ≥ 2 diagnosis codes for RA during the study period (Caserta: 2010-2018; Optum: 2010-2019) were identified. Baseline patient characteristics, as well as proportion of RA patients untreated/treated with NSAIDs/glucocorticoids/conventional DMARDs (csDMARDs)/biological/targeted synthetic DMARDs (b/tsDMARDs) during the first year of follow-up, and the proportion of RA patients with ≥ 1 switch/add-on between the first and the second year of follow-up, were calculated. These analyses were then stratified by age group (< 65; ≥ 65). RESULTS A total of 9227 RA patients from Caserta and 195,951 from Optum databases were identified (two-thirds were females). During the first year of follow-up, 45.9% RA patients from Optum versus 79.9% from Caserta were exclusively treated with NSAIDs/glucocorticoids; 17.2% versus 11.3% from Optum and Caserta, respectively, were treated with csDMARDs, mostly methotrexate or hydroxychloroquine in both cohorts. Compared to 0.6% of RA patients from Caserta, 3.2% of the Optum cohort received ≥ 1 b/tsDMARD dispensing. Moreover, 61,655 (33.7%) patients from Optum cohort remained untreated compared to 748 (8.3%) patients from the Caserta cohort. The subgroup analyses stratified by age showed that 42,989 (39.8%) of elderly RA patients were untreated compared to 18,666 (24.9%) young adult RA patients in Optum during the first year of follow-up. Moreover, a higher proportion of young adult RA patients was treated with b/tsDMARDs, with and without csDMARDs, compared to elderly RA patients (Optum<65: 6.4%; Optum≥65: 1.0%; P-value < 0.001; Caserta<65: 0.8%; Caserta≥65: 0.1%; P-value < 0.001). Among RA patients untreated during the first year after ID, 41.2% and 48.4% RA patients from Caserta and Optum, respectively, received NSAIDs, glucocorticoids, and cs/b/tsDMARDs within the second year of follow-up. Stratifying the analysis by age groups, 50.6% of untreated young RA patients received study drug dispensing within the second year of follow-up, compared to only 36.7% of elderly RA patients in Optum. Interestingly, more young adult RA patients treated with csDMARDs during the first year after ID received a therapy escalation to b/tsDMARD within the second year after ID in both cohorts, compared to elderly RA patients (Optum<65: 7.8%; Optum≥65: 1.8%; Caserta<65: 3.2%; Caserta≥65: 0.6%). CONCLUSIONS Most of RA patients, with heterogeneous baseline characteristics in Optum and Caserta cohorts, were treated with anti-inflammatory/csDMARDs rather than bDMARDs/tsDMARDs during the first year post-diagnosis, especially in elderly RA patients, suggesting a need for better understanding and dealing with barriers in the use of these agents for RA patients. Key Points • Substantial heterogeneity in baseline characteristics and access to bDMARD or tsDMARD drugs between RA patients from the United States and Italy exists. • Most of RA patients seem to be treated with anti-inflammatory/csDMARD drugs rather than bDMARD/tsDMARD drugs during the first year post-diagnosis. • RA treatment escalation is less frequent in old RA patients than in young adult RA patients. • An appropriate use of DMARDs should be considered to achieve RA disease remission or low disease activity.

Abstract
INTRODUCTION Spinal muscular atrophy (SMA) is a genetic, neuromuscular disease caused by deletions and/or mutations in the survival of motor neuron 1 (SMN1) gene leading to reduced SMN protein levels. Nusinersen, an intrathecally administered antisense oligonucleotide therapy that increases SMN protein levels, is approved for use in adult and pediatric patients with SMA. Data to inform real-world patient adherence and persistence to nusinersen are limited, with disparities in the population with SMA, study design, and results. The objective of this study is to characterize real-world nusinersen adherence and persistence in patients with SMA. METHODS This retrospective study examined nusinersen adherence and persistence over a 2-year period in patients with SMA in the USA from the IQVIA PharMetrics Plus claims database. Patients were followed from the date of first evidence of nusinersen treatment (occurring after 1 July 2017) until the end of the study period (31 December 2019) or end of continuous pharmacy and medical benefit enrollment, whichever came first. Subgroup analyses for nusinersen adherence and persistence were performed on the basis of age and presence or absence of spinal complications. RESULTS The final cohort consisted of 179 patients with SMA treated with nusinersen. Adherence to nusinersen treatment was 41% at 56 weeks and 39% at 104 weeks. In the base-case persistence analysis, there was a decrease in persistence before 6 months (67%) and further decline at 1 (57%) and 2 years (55%). Patients with spinal complication versus without had numerically higher persistence with nusinersen. CONCLUSIONS The findings suggest that adherence and persistence to nusinersen treatment appear low. Demographic (age ≥ 18 years) and clinical factors (no spinal complications) may contribute to nusinersen treatment discontinuation. Future research should explore possible reasons for low adherence and persistence to nusinersen treatment, such as clinical or logistical factors, patient preferences, and payer restrictions.

Abstract
BACKGROUND The decrease in mortality rate owing to asthma has slowed in recent years. A large proportion of patients with asthma remain uncontrolled in Japan. This study aimed to determine the prevalence of short-acting beta 2 agonists (SABA) overuse and its associated factors. METHODS This large-scale retrospective cohort study analyzed continuously treated patients with asthma aged 15-74 years between January 2017 and December 2017 using a Japanese insurance claims database. Characteristics, disease information, and prescribed drugs were extracted from the database, and treatment steps were defined according to drug combinations based on the criteria of the Japanese asthma guidelines. SABA overuse was defined as ≥3 canisters per year. Factors associated with SABA overuse were estimated using multivariable logistic regression. RESULTS Among 7,483 patients with mild-to-moderate asthma, 7,001 (93.6%) and 482 (6.4%) had low and high SABA use, respectively. Inhaled corticosteroids (ICS)/long-acting β-agonists (LABA) were the main asthma control treatments. The proportions of patients who overused SABA were 347 (9.9%) and 1,201 (5.6%) in the ICS and ICS/LABA groups, respectively. The factors associated with SABA overuse were male sex, ICS monotherapy, higher treatment steps, no history of allergic rhinitis, no history of chronic sinusitis, and no asthma management. CONCLUSIONS There is a relatively low prevalence of SABA overuse among asthmatic patients in Japan. ICS/LABA therapy, treatment steps, allergic rhinitis, chronic sinusitis, and asthma management are associated with a decreased risk of SABA overuse. Further studies are needed to investigate the association between SABA overuse and asthma exacerbation and mortality.

Abstract
PURPOSE To characterize delays in diagnosis and treatment of retinal detachments (RDs) in a pediatric population. DESIGN Retrospective cohort study using insurance claims data. SUBJECTS Pediatric patients with RD who underwent repair in the outpatient setting. METHODS A retrospective analysis of commercially insured patients from a national cohort (IBM MarketScan Research Databases) aged ≤ 18 years with an incident diagnosis of RD between 2007 and 2016. Patients with preceding eye-related visits, time to diagnosis, and time to repair were calculated and compared between patients with pre-existing ocular diagnosis and those without. MAIN OUTCOME MEASURES The time from diagnosis to specialist consultation, time from diagnosis to repair, time from specialist consultation to repair, number of preceding visits, and presence of previous eye-related diagnosis. RESULTS Our sample consisted of 826 patients, the majority (77%) of whom were diagnosed with rhegmatogenous RD. Only 40% of patients had at least 1 preceding eye-related visit, and 33% had at least 2 visits before RD diagnosis, with a median time from the last eye-related visit of 32 days (4-197 days) and median time from the second to last visit of 118 days (24-437 days). The median time from RD diagnosis to repair was 2 days (0-9 days). The 323 (37.9%) patients with pre-existing ocular diagnoses more frequently had at least 1 (44% vs. 37%; P = 0.079) or 2 preceding eye-related visits (40% vs. 29%; P = 0.002) compared with those without and also had a shorter time to RD diagnosis (median, 14.5 days vs. 44.5 days; P = 0.011) and repair (1 day vs. 3 days; P = 0.003). CONCLUSIONS Retinal detachment is an important cause of morbidity in children. This work highlighted how pediatric patients without previous ocular diagnoses and visits with eye care professional may have a delayed diagnosis and repair of their RD.

Abstract
INTRODUCTION Although the prevalence and burden of asthma are continuously increasing, there is a lack of evidence on the landscape of moderate-to-severe asthma in Japan. Here, we report the prevalence of moderate-to-severe asthma and describe patient's demographics and clinical characteristics from 2010 to 2019 using the JMDC claims database. METHODS Patients (≥12 years) from the JMDC database with ≥2 asthma diagnoses in 2 different months in each index year were stratified as moderate-to-severe asthma based on the definition of asthma prevention and management guideline (Japanese Guidelines for Asthma, JGL) or Global Initiative for Asthma (GINA). PRIMARY OBJECTIVE 10-year trend (2010-2019) in the prevalence of moderate-to-severe asthma. SECONDARY OBJECTIVE Demographics and clinical characteristics of patients from 2010 to 2019. RESULTS Of 7,493,027 patients from the JMDC database, 38,089 and 133,557 were included in JGL and GINA cohorts, respectively, by 2019. Both cohorts presented an increasing trend in the prevalence rate of moderate-to-severe asthma from 2010 to 2019, irrespective of age groups. Demographics and clinical characteristics were consistent across the cohorts in each calendar year. Majority of patients were in the age group of 18-60 years in both JGL (86.6%) and GINA (84.2%) cohorts. Allergic rhinitis was the most frequent comorbidity and anaphylaxis the least frequent comorbidity reported in both the cohorts. CONCLUSIONS In Japan, the prevalence rate of patients with moderate-to-severe asthma, as per JGL or GINA in the JMDC database, increased from 2010 to 2019. The demographics and clinical characteristics were similar in both cohorts over the assessment duration.

Abstract
BACKGROUND The observational, real-world evidence FLIEDER study aimed to describe patient clinical characteristics and investigate clinical outcomes in non-diabetic patients with chronic kidney disease (CKD) using data collected from routine clinical practice in the United States. METHODS Between 1 January, 2008-31 December, 2018, individuals aged ≥ 18 years, with non-diabetic, stage 3-4 CKD were indexed in the Optum® Clinformatics® Data Mart US healthcare claims database using International Classification of Diseases-9/10 codes for CKD or by laboratory values (estimated glomerular filtration rate [eGFR] 15-59 mL/min/1.73 m2). The primary outcomes were hospitalization for heart failure, a composite kidney outcome of end-stage kidney disease/kidney failure/need for dialysis and worsening of CKD stage from baseline. The effects of the intercurrent events of a sustained post-baseline decline in eGFR ≥ 30%, ≥ 40%, and ≥ 57% on the subsequent risk of the primary outcomes were also assessed. RESULTS In the main study cohort (N = 504,924), median age was 75.0 years, and 60.5% were female. Most patients (94.7%) had stage 3 CKD at index. Incidence rates for hospitalization for heart failure, the composite kidney outcome, and worsening of CKD stage from baseline were 4.0, 10.3, and 4.4 events/100 patient-years, respectively. The intercurrent event analysis demonstrated that a relative decline in kidney function from baseline significantly increased the risk of cardiorenal events. CONCLUSIONS This real-world study highlights that patients with non-diabetic CKD are at high risk of serious adverse clinical outcomes, and that this risk is amplified in patients who experienced greater post-baseline eGFR decline.

Abstract
BACKGROUND Heart failure (HF) registries include rich data on patient inclusion characteristics, but follow-up information is often incomplete. Medicoadministrative databases may provide less clinical information than registries, e.g. on left ventricular ejection fraction (LVEF), but long-term data are exhaustive and reliable. The combination of the two types of database is therefore appealing, but the feasibility and accuracy of such linking are largely unexplored. AIMS To assess the feasibility and accuracy of linking an HF registry (FRESH; FREnch Survey on Heart Failure) with the French National Healthcare System database (SNDS). METHODS A probabilistic algorithm was developed to link and match patient data included in the FRESH HF registry with anonymized records from the SNDS, which include: hospitalizations and diagnostic codes; all care-related reimbursements by national health system; and deaths. Consistency was assessed between deaths recorded in the registry and in the SNDS. A comparison between the two databases was carried out on several identifiable clinical characteristics (history of HF hospitalization, diabetes, atrial fibrillation, chronic bronchopneumopathy, severe renal failure and stroke) and on events during 1-year follow-up after inclusion. RESULTS Of 2719 patients included in the FRESH registry (1049 during decompensation; 1670 during outpatient follow-up), 1885 could be matched with a high accuracy of 94.3% for deaths. Mortality curves were superimposable, including curves according to type of HF and LVEF. The rates of missing data in the FRESH registry were 2.3-8.4% for clinical characteristics and 17.5% for hospitalizations during follow-up. The discrepancy rate for clinical characteristics was 3-13%. Hospitalization rates were significantly higher in the SNDS than in the registry cohort. CONCLUSIONS The anonymous matching of an HF research cohort with a national health database is feasible, with a significant proportion of patients being accurately matched, and facilitates combination of clinical data and a reduced rate of losses to follow-up.

Abstract
OBJECTIVES The COVID-19 pandemic has forced people to change many behaviours, including physical distancing, hygiene measures and lifestyles. This study aimed to evaluate the indirect impact of the COVID-19 pandemic on the incidence of non-COVID-19 infections and medical care costs/visits using health insurance claims. STUDY DESIGN This was an observational study using patient-based administrative claims covering approximately 800,000 insured persons and their dependents in the Mie Prefecture in Japan. METHODS This study identified non-COVID-19 infectious disease incidences, number of outpatient visits and healthcare costs between 2017 and 2021. Each year was divided into quarters. The adjusted incidence rate ratios (IRRs) during the pandemic (January 2020 to September 2021) and during the prepandemic period (January 2017 to December 2019) were determined using Poisson regression. RESULTS The adjusted influenza IRRs from April 2020 were close to zero. The incidence of upper respiratory tract infections and bacterial pneumonia was significantly reduced (IRRs range: 0.39-0.73 and 0.43-0.84, respectively). Gastrointestinal and urinary tract infection incidences decreased by approximately 30% and 10%, respectively. In contrast, sexually transmitted infections (STIs), including syphilis, gonococcal infection and Chlamydia trachomatis infection, did not decrease during the pandemic but increased significantly between April and June 2021 (adjusted IRR, 1.37; 95% confidence interval, 1.18-1.60). The adjusted IRRs for outpatient visits and healthcare costs were 0.86-0.93 and 0.91-0.97, respectively. CONCLUSIONS In contrast to other infections, STIs did not decrease during the COVID-19 pandemic. The IRR of STIs during the pandemic period is an area of public health concern. Appropriate screening and medical consultations are strongly recommended.

Abstract
BACKGROUND The epidemiology and payer costs for ankle fractures are not well documented. This study evaluated: (1) the incidence of ankle fracture and ankle surgery following fracture in the US population; and (2) the clinical presentation of patients presenting with ankle fractures requiring surgery, their complication rates, and payer costs. METHODS Patients in the IBM® MarketScan® Commercial and Medicare Supplemental databases with an inpatient/outpatient diagnosis of ankle fracture from 2016 to 2019 were stratified by age group and gender, and rates of fracture per 10,000 enrollees were estimated. Surgically-treated patients between January 2016 - October 2021 were further analyzed. One-year post-surgical outcomes evaluated complication rates (e.g., infection, residual pain), reoperations, and 1-year payments. Standard descriptive statistics were calculated for all variables and outcomes. Generalized linear models were designed to estimate payments for surgical care and incremental payments associated with postoperative complications. RESULTS Fracture cases affected 0.14% of the population; 23.4% of fractures required surgery. Pediatric and elderly patients were at increased risk. From 3 weeks to 12 months following index ankle surgery, 5.5% (5.3% - 5.7%) of commercially insured and 5.9% (5.1% - 6.8%) of Medicare patients required a new surgery. Infection was observed in 4.4% (4.2% - 4.6%) commercially insured and 9.8% (8.8% - 10.9%) Medicare patients, and residual pain 3 months post-surgery was observed in 29.5% (28.7% - 30.3%) commercially-insured and 39.3% (36.0% - 42.6%) Medicare patients. Commercial payments for index surgery ranged from $9,821 (95% CI: $9,697 - $9,945) in the ambulatory surgical center to $28,169 (95% CI: $27,780 - $28,559) in the hospital inpatient setting, and from $16,775 (95% CI: $16,668 - $16,882) in patients with closed fractures, to $41,206 (95% CI: $38,795 - $43,617) in patients with Gustilo III fractures. Incremental commercial payments for pain and infection averaged $5,200 (95% CI: $4,261 - $6,139) and $27,510 (95% CI: $21,759 - $33,261), respectively. CONCLUSION Ankle fracture has a high incidence and complication rate. Residual pain affects more than one-third of all patients. Ankle fracture thus presents a significant societal impact in terms of patient outcomes and payer burden.

Abstract
BACKGROUND The introduction of novel systemic therapies for metastatic renal cell carcinoma (mRCC) over the last decade has significantly improved patient outcomes. Little information is available on treatment modalities and outcomes in everyday practice. The objective of this study was to describe patient characteristics, treatment patterns, and healthcare resource use in mRCC patients receiving systemic therapy in France (2014-2017), using the nationwide claims database. PATIENTS AND METHODS Patients with a diagnosis of RCC (ICD-10: C64) between 2009 and 2017 and receiving a first systemic treatment for mRCC between 2014 and 2017 were eligible. Patients were divided into two groups at diagnosis, Group A: metastatic RCC and Group B: localized RCC. RESULTS 4,929 eligible patients were identified (Group A: 2638 patients, 53.5%; Group B: 2,291 patients,46.5%). Median age was 66 years and 73% were men. In patients with incident RCC (N = 3,425), 62.3% underwent nephrectomy (94.4% in Group B). Within the year following mRCC diagnosis, 86.5% were hospitalized at least once; among them 58.1% for RCC. Nearly 31% of patients underwent radiotherapy. First line treatment was sunitinib for 65% of patients and pazopanib for 24%. Twenty five percent and 10% of patients received 2 and 3 lines of systemic treatment, respectively. The 2-year survival rate after mRCC diagnosis was 44%, with median overall survival of 20 [95%CI: 19-21] months (14 and 28 in Group A and B). CONCLUSION This study documented patient characteristics, treatment patterns and survival outcomes in mRCC patients receiving systemic therapy in France (2014-2017). Estimated survival rates were consistent with real-world studies from other countries.

Abstract
AIMS/INTRODUCTION This study was designed and carried out to investigate the association of dipeptidyl peptidase-4 inhibitor (DPP-4i) use with pancreatic cancer (PC) in individuals with diabetes in Japan. MATERIALS AND METHODS The JMDC Claims Database, which contains the medical and prescription information of Japanese employment-based health insurance programs, was used. The primary outcome was duration to the first occurrence of PC (International Classification of Diseases 10th Revision code C25), both all and hospitalized, from prescription of DPP-4is or other oral glucose-lowering agents (GLAs). RESULTS Individuals with diabetes who received DPP-4is (n = 61,430) or other oral GLAs (n = 83,304) were analyzed. Follow-up periods (median [interquartile range]) were 17 months (8-33) for DPP-4is and 14 months (7-28) for other oral GLAs. Kaplan-Meier curve analysis to determine the duration of first use of DPP4i or other oral GLA to diagnosis of PC disclosed no differences between the two groups in duration to all or hospitalized PC (log-rank test: all, P = 0.7140; hospitalized, P = 0.3446). Cox proportional hazards models showed that use of DPP-4is did not affect the PC risk adjusted for medications, age, sex and risk comorbidities (all, hazard ratio 1.1, 95% confidence interval 0.8-1.3, P = 0.6518; hospitalized, hazard ratio 1.1, 95% confidence interval 0.8-1.4, P = 0.6662). Similar results were obtained when individuals with ≥2 years oral GLA treatment and those with medical checkup data (e.g., smoking or drinking habit) available were analyzed. CONCLUSION This database study shows that there is not a significant PC risk due to DPP-4i treatment in individuals with diabetes in Japan, but larger studies with longer follow up are required to confirm these findings.

Abstract
The objectives of this study were to describe prevalence, incidence, and medications among patients who were diagnosed with narcolepsy in Japan using a claims database. Patients diagnosed with narcolepsy were identified from January 2010 to December 2019 using an employment-based health insurance claims database compiled by JMDC Inc. The prevalence and incidence of narcolepsy were estimated annually in the overall population and by age and sex among employees and their dependents aged < 75 years. Medications, examined for each quarter in the overall population, were modafinil, methylphenidate, pemoline, tricyclic antidepressants, selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors. We identified 1539 patients with narcolepsy. The overall annual prevalence increased from 5.7 to 18.5/100,000 persons in 2010 and 2019, respectively. Large increases were found from 2010 to 2019 in patients aged 20-29 years and 10-19 years, with the highest prevalence in 2019 (9.7-37.5/100,000 persons and 5.0-27.1/100,000 persons). The overall incidence slightly increased from 3.6 to 4.3/100,000 person-year from 2010 to 2019, and the highest incidence was found in patients aged 20-29 years and 10-19 years (5.8-11.3/100,000 person-year, and 3.8-7.4/100,000 person-year from 2010 to 2019, respectively). Methylphenidate and modafinil were commonly prescribed in 2010 (27.3-38.9% and 17.5-45.5%, respectively). Methylphenidate prescriptions declined during the 10 years, whereas modafinil prescriptions increased (15.6-17.1% and 43.8-45.8% in 2019, respectively). The estimated prevalence and incidence of narcolepsy appeared to increase from 2010 to 2019, especially in teenagers and 20-year olds.

Abstract
UNLABELLED In Japanese patients who experienced an osteoporotic fracture, 10.8% and 18.6% had a subsequent fracture within 1 and 2 years of follow-up, respectively. Although the burden of hip and vertebral fractures has been reported widely, we found that patients with non-hip non-vertebral (NHNV) fractures had a 26% higher risk of subsequent fracture than patients with hip fractures; therefore, NHNV fractures should also be considered an important risk factor for subsequent fracture. INTRODUCTION To investigate imminent risk and odds of subsequent osteoporotic fractures and associated risk factors in patients who experienced an initial osteoporotic fracture. METHODS Patients aged ≥ 50 years with ≥ 1 osteoporotic fracture were analyzed from Japan's Medical Data Vision (MDV) database of claims from acute-care hospitals (January 2012-January 2017). Multivariable models were constructed to explore the impact of key comorbidities and medications on the subsequent fracture risk: Cox proportional hazards model for time to subsequent fracture and logistic regression models for odds of subsequent fracture within 1 and 2 years from index fracture. RESULTS In total, 32,926 patients were eligible with a median follow-up duration of 12.3 months. The percentage of patients experiencing subsequent fractures was 14.1% across the study duration, and 10.8% and 18.6% in patients with 1 and 2 years of follow-up, respectively. In the Cox proportional hazards model, patients with vertebral or NHNV index fractures had a higher subsequent fracture risk than patients with a hip index fracture (adjusted hazard ratio [aHR] 1.11 and 1.26, respectively); subsequent fracture risk was lower in males than females (aHR 0.89). Patients with baseline claims for tranquilizers and glucocorticoids had a higher subsequent fracture risk than those without (aHR 1.14 and 1.08, respectively). Additionally, baseline claims for anti-Parkinson's medications, alcoholism, and stage 4/5 chronic kidney disease were significantly associated with higher odds of subsequent fracture in the logistic regression models. CONCLUSION Several clinical and demographic factors were associated with a higher risk and odds of subsequent fracture. This may help to identify patients who should be prioritized for osteoporosis treatment.

Abstract
Background Multiple inhaler triple therapy (MITT), comprising inhaled corticosteroids (ICS), long-acting beta-agonists (LABA), and long-acting muscarinic antagonists (LAMA), has been used as an escalation treatment for patients with chronic obstructive pulmonary disease (COPD). However, real-world use of MITT has not been investigated in Asia, including South Korea. This study reports baseline characteristics of patients with COPD initiated on MITT in South Korea, and their treatment patterns. Healthcare resource utilization (HRU) and costs associated with COPD exacerbations following MITT initiation were also assessed. Methods This was a retrospective cohort study using the South Korea National Health Insurance database (2014–2018). Included patients were ≥ 40 years, had a COPD diagnosis, were newly initiated on MITT and had ≥ 12 months’ data both before (baseline) and after index date (the first day with overlapping supply of all MITT components). Treatment immediately before initiation and immediately following discontinuation of MITT were identified, and proportion of days covered (PDC) by MITT was calculated. HRU and costs (per person per year [PPPY]) associated with exacerbations were identified following MITT initiation; costs were calculated using the average 2020 exchange rate (0.0008 USD/KRW). Results Among 37,400 patients, the mean age was 69 (SD 10) years and 73% were males; 56% had ≥ 1 COPD exacerbation during the baseline period, with a mean of 2 (SD 5) events/year. ICS/LABA was the most frequent regimen prescribed immediately before initiation (37%) and immediately following discontinuation (41% of 34,264 patients) of MITT. At 3, 6, and 12 months from treatment initiation, mean PDC was 81%, 63% and 49%, respectively; median treatment duration was 102 days. The mean (95% confidence interval [CI]) number of total visits for severe COPD exacerbations was 0.77 PPPY (0.75–0.78); mean PPPY total healthcare costs were 2093 USD. Conclusions Patients with COPD in South Korea experienced frequent exacerbations prior to MITT, and PDC by MITT was low. Patients may benefit from early optimization of COPD therapy, and greater emphasis on adherence to inhaled COPD therapy. Severe exacerbations were found to incur substantial costs; treatment alternatives that can reduce the rate of severe exacerbations are likely to minimize healthcare costs.

Abstract
PURPOSE This study sought to describe patient characteristics and treatment patterns among patients with insomnia prescribed trazodone in the United States. METHODS This real-world, retrospective, descriptive cohort study used US commercial insurance claims from July 1, 2009, through June 30, 2019. The index date was the first prescription for trazodone between January 1, 2010, and December 31, 2018, with 6 months for the preindex period and ≥6 months for the postindex period. FINDINGS Among 5.8 million patients with insomnia, 17.7% were prescribed trazodone, and 357,380 adults (6.2%) and 7564 children (0.1%) met the study eligibility criteria. The mean (SD) age was 48.8 (15.8) years for adults and 14.8 (2.7) years for pediatrics. Most patients were female (229,280 adults [64.2%] and 4481 children [59.2%]). Insomnia due to mental disorder was the most common specific diagnosis. The most common (>25%) comorbid conditions were anxiety, depression, and hypertensive disease, and 1 of 10 had a history of substance abuse. Zolpidem was previously prescribed (73,342 adults [20.5%] and 233 children [3.1%]) and continued to be prescribed. Concomitant antidepressants were most common (216,893 adults [60.7%] and 5414 children [71.6%]), but benzodiazepines (132,740 adults [37.1%] and 1188 children [15.7%]), antiepileptics (115,064 adults [32.2%] and 2103 children [27.8%]), nonbenzodiazepines (90,946 adults [25.4%] and 542 children [7.2%]), and antipsychotics (40,490 adults [11.3%] and 2063 children [27.3%]) were also prescribed. IMPLICATIONS This study provides current evidence that trazodone use is widespread among patients with insomnia and is often associated with other specific comorbidities, such as psychiatric conditions. A deeper knowledge of the real-world management of patients with insomnia may facilitate steps toward improving sleep quality, daytime functioning, and clinical outcomes for patients.

Abstract
Introduction Atopic dermatitis (AD) data are scarce in Dubai [United Arab Emirates (UAE)]. Therefore, this study aimed at understanding real-world healthcare resource utilization (HCRU) and related costs, specialties, treatment landscape, consultation-based prevalence and incidence, and patient characteristics. Methods This retrospective, longitudinal, insurance e-claims (Dubai Private Insurance-insured expatriates) database studied AD in Dubai between 1 January 2014 and 31 March 2020. Two cohorts of patients based on treatment status as the eligibility criteria were selected from 442,956 patients with at least two AD diagnosis claims: treated AD [mild to moderate (10,134 patients) and moderate to severe (3515 patients)] and untreated or on drugs not included in the treated AD cohort (10,806 patients). Results Across treated AD (mild to moderate and moderate to severe) and untreated AD cohorts, mean age was ~ 29 years; the majority were from dermatology (65-44%) and pediatrics (29-32%) specialty. Key HCRU cost contributors were hospitalizations and outpatient visits in both the treated AD groups. Mean annual disease-specific HCRU cost per patient was highest for the moderate-to-severe treated (531.5 USD) cohort, followed by the mild-to-moderate treated (378.4 USD) cohort, and lowest for the untreated (144.0 USD) cohort; patients with AD with any infection, asthma, or allergic rhinitis showed a similar trend. However, AD-diagnosed patients with Staphylococcus infection had the highest mean HCRU cost among the mild-to-moderate treated AD cohort, followed by the moderate-to-severe treated AD cohort. Conclusion This study indicated AD to be a common skin disease with a prevalence rate of 4-5% in Dubai (UAE), with the majority of patients (about 90%) being treated by specialists. However, there is a significant underuse of newer innovative therapies (including biologics). Also, disease severity (moderate-to-severe AD) was associated with high direct medical cost, which could be controlled by early intervention. Furthermore, AD treatment choice could focus on major direct HCRU cost contributors such as hospitalizations, comorbid conditions, and infections.

Abstract
Introduction The healthcare situation of multiple sclerosis (MS) and its course are not being thoroughly investigated in Japan. We aimed to examine the current healthcare situation, including treatment and healthcare costs, of MS according to duration since its first diagnosis using Japanese real-world data to determine unidentified healthcare issues at each disease stage. Methods This retrospective, non-comparative, non-interventional study used a Japanese nationwide claims database (April 2008–August 2018) comprising 20 million patients from 329 acute care hospitals (as of June 2018). Treatment patterns, comorbidities, healthcare resource utilization, and healthcare costs were analyzed using longitudinal analyses of patients with MS according to duration since the first diagnosis. The time from diagnosis to first treatment was examined using Kaplan–Meier analysis. Results We identified 7067 patients with MS [mean (standard deviation) age at first diagnosis 45.0 (16.2) years]. About 70% of the patients did not receive disease-modifying therapy (DMT) within the first year of diagnosis. The frequency of DMT use decreased in patients with a longer duration since the first diagnosis. MS treatment costs tended to increase with a longer duration from the first diagnosis until 9 years, followed by a tendency to decrease; contrastingly, other healthcare costs tended to increase with duration after decreasing from the year of the first diagnosis to the next year. The frequencies of hospitalizations and hospital visits, healthcare costs—excluding those for MS treatment and tests—and prevalence of comorbidities tended to be higher in patients with a longer duration since the first diagnosis. Conclusion A considerable proportion of patients did not receive DMT, suggesting that patients with early-stage MS may lose the opportunity to improve their prognosis through early intervention with DMT. Among patients with a longer duration since the first diagnosis, fewer treatment choices may be available despite the larger clinical and treatment burden.

Abstract
Introduction This study characterized real-world demographic and baseline clinical characteristics, as well as treatment persistence and adherence, in patients with psoriatic arthritis (PsA) who had newly initiated tofacitinib treatment. Methods This retrospective cohort study included patients aged 18 years or older in the IBM MarketScan™ US database with at least one tofacitinib claim (first = index) between December 14, 2017 and April 30, 2019; PsA diagnoses on/within 12 months pre-index; and no diagnoses of rheumatoid arthritis any time pre-index. Patients were continuously enrolled for 12 months pre-index and 6 months post-index, with no pre-index claims for tofacitinib. Patient demographic and clinical characteristics on the day of index, and history of advanced treatments (including tofacitinib monotherapy or combination therapy), were recorded. Outcomes at 6 months post-index included tofacitinib persistence (less than 60-day gap without tofacitinib treatment) and adherence (proportion of days covered [PDC] and medication possession ratio 80% or higher). Results Of the 10,354 patients with tofacitinib claims within the study period, 318 patients with PsA met the inclusion criteria. More than 60% of patients received tofacitinib monotherapy post-index, with a mean duration of PsA of 760.5 days at index. For patients who received tofacitinib combination therapy post-index, methotrexate was the most common concomitant conventional synthetic disease-modifying antirheumatic drug. At 6 months post-index, persistence was similar in patients receiving tofacitinib monotherapy (69.8%) versus combination therapy (73.1%); adherence (as measured by PDC ≥ 0.8) was numerically lower in patients receiving tofacitinib monotherapy (56.8%) versus combination therapy (65.5%). Conclusions This analysis of US-based claims data described patients who had newly initiated tofacitinib treatment an average of 2 years after PsA diagnosis, with approximately two-thirds of patients receiving tofacitinib monotherapy. Observed rates of tofacitinib persistence were similar across patients who received tofacitinib monotherapy and combination therapy 6 months after initiation; adherence rates were numerically lower in patients receiving monotherapy. Graphical Abstract ![]()
Tofacitinib is a drug approved to treat patients with psoriatic arthritis (PsA) that has been shown to improve PsA symptoms and quality of life in controlled clinical trials. However, there is not much information on everyday use of tofacitinib outside of clinical trials in the USA. This study is one of the first to describe the characteristics of patients with PsA in the USA who take tofacitinib, including their typical age, sex, where they live, how long they have had PsA, and how they use tofacitinib. Use of tofacitinib included how patients followed tofacitinib prescription timings and dose (adherence) and how long they took tofacitinib for after it was prescribed (persistence). We used data collected from a US health insurance claims database (IBM MarketScan™) for patients with PsA and at least one claim for tofacitinib. In total, 318 patients were included and over 60% of them received tofacitinib therapy only (monotherapy; no conventional synthetic disease-modifying antirheumatic drug [csDMARD] therapy). For patients treated with both tofacitinib and a csDMARD (combination therapy), methotrexate was the most common drug prescribed. Six months after their first prescription of tofacitinib, around 70% of patients were still taking tofacitinib (monotherapy or combination therapy). However, a slightly lower number of patients taking tofacitinib monotherapy were taking it as originally instructed (adherence 57%), compared with those taking tofacitinib combination therapy (adherence 66%). Our results provide valuable information on the use of tofacitinib in US real-life settings outside of clinical trials and could help to improve the quality of care for patients with PsA.

Abstract
Purpose As the cancer survivors increase, patients using long-term and high-dose opioids are also increasing. Therefore, the promotion of appropriate use is important. This study investigated the actual status of opioid prescriptions in Japan and identified factors associated with long-term, high-dose prescription. Methods We conducted a case-control study using a hospital-based administrative claims database. Patients with a diagnosis of cancer and prescriptions of opioids were included. Patients who received continuous opioid for less than 183 days were defined as the “control,” and patients who received continuous opioid at higher dose levels (≥ 120 mg/day of oral morphine equivalent) for 183 days or more were defined as the “case.” The case was subdivided into two groups: those with the duration of less than 730 days (case I) and 730 days or more (case II). After describing factors possibly associated with long-term, high-dose opioid prescription, ordinal logistic regression analysis was conducted. Results We included 19,176 patients; of these, 13,517 were in the control, 111 were in the case I, and 682 were in the case II. The analysis showed that distant metastasis, back pain, dose of opioids, non-opioid analgesics, prescription, and chemotherapy during the opioid prescriptions were significantly associated with long-term, high-dose opioid prescription. Conclusion Four percent of the study population were prescribed long-term, high-dose opioids, and several comorbidities and concomitant medications were identified as associated factors. Opioids might be also prescribed for non-cancer chronic pain. It is necessary to properly distinguish the type of pain and to use opioids safely and appropriately.

Abstract
Introduction Noncommunicable diseases (NCDs) are an ongoing public health problem globally. The present study aimed to estimate the prevalence of NCDs in Japan using a newly developed, commercially available administrative claims database covering young, middle-aged, and elderly people. Methods We compared the age-stratified population distribution between the DeSC administrative claims database and the population estimates. We calculated the 1 year prevalence of several NCDs using the DeSC database and compared the prevalence of diabetes mellitus and hypertension between the DeSC database and the Japan National Health and Nutrition Survey. Results The age distribution of the population included in the DeSC database was similar to that of the population estimates. The estimated prevalence rates were as follows: diabetes mellitus (12.2%), hypertension (20.9%), ischemic heart disease (5.6%), heart failure (5.3%), cerebral infarction (3.4%), stroke (3.7%), gastric cancer (0.6%), colorectal cancer (0.8%), breast cancer (1.5%), prostate cancer (0.6%), cataract (7.1%), depression (3.5%), and osteoporosis (6.3%). The estimated prevalence of diabetes and hypertension was comparable with that of the National Health and Nutrition Survey. Conclusions The distribution of age and sex in the database was comparable with that of the population estimates. The prevalence of diabetes mellitus and hypertension was comparable with that in a previously reported national survey. Our data can be utilized as basic information for policymaking in clinical medicine and public health in Japan.

Abstract
INTRODUCTION We aimed to describe healthcare resource utilization (HCRU) patterns and costs in patients with fibrosing interstitial lung disease (ILD) and those with a progressive phenotype of fibrosing ILD in a US claims database. METHODS Data from the IBM® MarketScan® databases (1 October 2011-30 September 2015) were used. Diagnosis codes documented on medical claims on two occasions (without any claims during the 12 months prior) identified patients with incident fibrosing ILD. Patients with chronic fibrosing ILD with a progressive phenotype were identified by proxies for progression. Patients aged ≥ 18 years with 365 days of continuous coverage before the index date were eligible for inclusion. Data were analyzed for 12 months prior to identification of fibrosing ILD/progressive phenotype (baseline) and 12 months after (follow-up). Outcomes included treatment patterns, outpatient and inpatient claims, and costs. RESULTS We identified 23,577 patients with incident fibrosing ILD and 14,722 with the progressive phenotype. Follow-up data were available for 9986 and 5840 patients, respectively. The most frequent ILD-related medications during baseline were corticosteroids (49.4% and 56.6%). Mean (± standard deviation [SD]) annualized number of outpatient claims was 30.0 (± 26.4) and 34.1 (± 27.7) in the baseline period and 36.2 (± 28.6) and 41.9 (± 30.2) in the follow-up in fibrosing ILD and with a progressive phenotype, respectively. Mean (SD) number of all-cause hospitalizations was 0.5 (± 1.1) and 0.7 (± 1.2) during baseline and 0.6 (± 1.1) and 0.7 (± 1.2) during follow-up. Mean (SD) total costs were $40,907 (± 92,496) and $49,561 (± 98,647) during baseline and $46,157 (± 102,858) and $54,215 (± 116,833) during follow-up. Inpatient mortality during follow-up was 53.50 and 77.44 per 1000 patient-years. CONCLUSION HCRU and costs were high in patients with chronic fibrosing ILD with a progressive phenotype, likely reflecting the disease severity and the need for close monitoring and acute care. Outpatient claims accounted for a substantial proportion of the total costs.

Abstract
INTRODUCTION Claims databases are preferred for research on multiple sclerosis (MS) as this condition is characterized by low prevalence and long disease course. However, Japanese claims databases contain no information on disease severity or disability status of MS. Here, we aimed to explore the possibility of utilizing a principal component analysis (PCA) to estimate MS severity using a Japanese claims database. METHODS An MS severity score was developed using a PCA. Factors related to functional systems for Expanded Disability Status Scale (EDSS) and higher disease severity (74 diagnoses, 68 drug prescriptions, and 77 procedures) were extracted from the claims database (April 2008-August 2018). The score (PC1 score) was developed for each patient-year-each year from the first diagnosis (excluding the year of the first diagnosis), based on the first principal component of the included factors. Finally, the patient-years were classified into quartiles based on the PC1 score, and demographic information and medical status were analyzed. RESULTS The database contained 7067 patients with MS. The highest score group had a higher mean age (55.4 ± 0.2 [mean ± standard error] years), lower percentage of women (64.4 ± 0.7%), and longer mean disease duration from first diagnosis (8.1 ± 0.1 years) than the lowest score group (43.3 ± 0.2 years, 68.4 ± 0.8%, and 6.0 ± 0.1 years, respectively). In addition, the PC1 score of each patient positively correlated with disease duration from diagnosis. CONCLUSION We developed a PC1 score to indicate MS severity using information from a Japanese claims database. Since changes in demographic features we observed are consistent with findings of previous research, this score might represent MS severity to some extent. Further research is necessary to validate this score with clinical measurement of disability such as the EDSS.

Abstract
PURPOSE To describe the trends in the pharmacological management of postmenopausal osteoporosis in France during the period 2007-2016. METHOD This cross-sectional, yearly repeated study of patients in France used the nationwide claims database 'Échantillon Généraliste de Bénéficiaires' (EGB), covering a 1 in 97 representative sample of approximately 600,000 individuals insured by the main French public insurance scheme. For women aged 50-89 years, prescriptions for all anti-osteoporosis medications (AOMs) marketed in France during the study period (bisphosphonates alone or used in combination with calcium, selective estrogen receptor modulators, strontium ranelate, teriparatide or denosumab) were identified in each calendar year. Initiation of any AOM in a calendar year was defined by the absence of a prescription for any AOM within the 2 previous calendar years. Incidence was calculated for all AOM prescriptions and initial prescriptions for AOM. RESULTS Marked changes were observed in the rates of women receiving any AOM, with a slight increase from 2007 to 2009 (from 10.22 to 10.42 per 100 patient-years [PY]), then a plateau in 2009-2010, followed by a rapid and more than twofold decrease until 2016 (from 10.39 to 5.02 per 100 PY). The decrease in the overall rate of women initiating an AOM showed a rapid halving from 2007 to 2012 (from 2.56 to 1.15 per 100 PY), followed by a plateau in the range of 0.90-1.0 per 100 PY during the period 2013-2016. In contrast, the use of calcium/vitamin D has been rapidly increasing as the only prevention and exclusive intervention for postmenopausal osteoporosis, from 10.6% of women in 2007 to 47.7% in 2016. The profile of patients initiating AOM changed substantially over the 10-year period. Despite a stable mean age of approximately 69 years, an increasing proportion of women with severe chronic comorbidities (from 34.9% to 43.3%), history of fractures (from 7.8% to 13.3%) or high-dose steroid use (from 2.9% to 8.4%) was observed. The decline of AOM initiation was associated with a marked reduction of prescriptions during the study period: by 64.2% for primary care physicians; by 36.7% for specialty doctors; and by 18.4% for rheumatologists. CONCLUSION These findings suggest a general trend toward an AOM uptake that is increasingly limited to a fraction of patients who are at high risk of fractures. In the context of an aging population and declining prescription rates for AOM, these data highlight an increasing treatment gap among women in France with osteoporosis, which is similar to that seen in other European countries and in the USA.

Abstract
INTRODUCTION Limited real-world data are available comparing multiple biologics on their adherence, persistence, and the use of concomitant biologics in the treatment of moderate-to-severe psoriasis in clinical practice. The objective was to compare persistence of and adherence to ixekizumab (IXE) treatment, as monotherapy or with concomitant medication, versus patients receiving other commonly prescribed biologics. METHODS Patients who newly initiated IXE, adalimumab (ADA), etanercept (ETN), secukinumab (SEC), or ustekinumab (UST) in IBM MarketScan® databases with diagnosis of psoriasis were identified. Treatment comparisons on medication persistence, adherence, and monotherapy were based on balanced samples after inverse probability of treatment weighting (IPTW). RESULTS A higher proportion of patients receiving IXE had had previous biologic therapies (50.3%) versus other biologics (ADA: 9.1%, ETN: 10.9%, SEC: 33.9%, UST: 19.7%). Patients treated with IXE showed statistically (p < 0.001) greater persistence than patients treated with SEC, ADA, UST, or ETN at both 1-year follow-up and up to 3 years of follow-up. Adherence for patients treated with IXE was significantly (p < 0.001) higher compared to ADA, ETN, and UST at both 1-year follow-up and up to 3 years of follow-up. There was no significantly higher adherence in patients treated with IXE compared to those treated with SEC at 1-year follow-up, but IXE had higher adherence than SEC (p < 0.05) at 1-3 year follow-up. IXE showed longer time on monotherapy than ADA (p < 0.001), ETN (p < 0.001), SEC (p < 0.05), and UST (p < 0.001) for both 1-year and 1-3 year follow-up. Sensitivity analyses on persistence, adherence, and monotherapy with further model adjustments after IPTW confirmed the findings. CONCLUSIONS Patients treated with IXE were more persistent on and adherent to treatment and remained on monotherapy longer compared to those on all other commonly prescribed biologics combined or with individual biologics.

Abstract
Introduction Spinal muscular atrophy (SMA) is a rare, genetic neuromuscular disorder caused by deletion/mutation of the survival motor neuron 1 gene, characterized by progressive loss of motor neurons, resulting in increasing muscular weakness, deteriorating motor function, and, in its most severe form, death before 2 years. Nusinersen, an antisense oligonucleotide that increases expression of the functional SMN protein, was approved for SMA by US and European regulatory agencies in 2016 and 2017, respectively. The indicated regimen requires intrathecal injections every 4 months, following the first four injections during the loading phase. Adherence is integral to treatment success. Adherence to nusinersen may pose particular challenges as most patients with SMA are young children who require complex multidisciplinary care (including ongoing intrathecal treatment administration and potential specialized anesthetic and surgical procedures) at specialized centers. However, real-world data on adherence to nusinersen are limited. Methods We conducted a retrospective claims database analysis from December 23, 2016, to November 20, 2019, to study nusinersen adherence and discontinuation/persistence in US patients with SMA types 1–3 who completed the loading phase, and to determine the impact of non-adherence or treatment discontinuation on SMA-related comorbidities, health care resource utilization (HCRU), and costs. Results We identified 23 patients with SMA type 1, 41 patients with SMA type 2, and 260 patients with SMA type 3 who had completed the loading phase. Deviations from the indicated nusinersen treatment schedule were frequent in real-world usage, with most patients receiving ≥1 dose outside the scheduled interval. Across SMA types, non-adherent patients were more likely to have had SMA-related comorbidities (e.g., feeding difficulties, dyspnea and respiratory anomalies, and muscle weakness) and greater HCRU. Persistence rates 12 months after treatment initiation for patients with SMA types 1, 2, and 3 were 55.2%, 42.4%, and 54.6%, respectively. Patients who discontinued nusinersen and those who did not had generally similar comorbidity profiles. Discontinuation was associated with greater health care costs across SMA types. Conclusion Our analysis of claims data indicated that discontinuation and non-adherence to nusinersen treatment were prevalent, and associated with greater frequency of comorbidities, greater HCRU, and increased costs for patients.

Abstract
AIM AND HYPOTHESES The THEMIS randomized trial compared ticagrelor plus aspirin versus placebo plus aspirin for patients with stable coronary artery disease and type 2 diabetes mellitus (CAD-T2DM), and without prior myocardial infarction (MI) or stroke. The aim of the study was to quantify the size of the CAD-T2DM population without prior MI or stroke population in a real-world setting, and more specifically populations with similar THEMIS selection criteria (THEMIS-like and THEMIS-PCI-like populations), as well as their risk of major outcomes in current practice. METHODS A 2-year follow-up cohort study included all CAD-T2DM without MI/stroke prevalent patients on January 1st, 2014 in the SNDS French nationwide claims database. The THEMIS-like population concerned those ≥ 50 years of age with similar THEMIS inclusion and exclusion criteria. Prevalence was standardized to the European population. The cumulative incidence function was used to estimate the incidence of clinical outcomes (MI, ischemic stroke, and major bleeding according to the TIMI classification) with death as competing risk, and the Kaplan-Meier estimate for all-cause death and a composite outcome of MI, stroke and all-cause death. RESULTS From a population of about 50 million adults, the prevalence of CAD-T2DM without MI/stroke, THEMIS-like and THEMIS-PCI-like populations was respectively at 6.04, 1.50 and 0.27 per 1000 adults, with a mean age of 72.7, 72.3 and 70.9 years and less comorbidities and diabetic complications for the THEMIS-like and THEMIS-PCI-like population. The 2-year cumulative incidence was respectively 1.7%, 1.3% and 1.6% for MI, 1.7%, 1.5% and 1.4% for stroke, 4.8%, 3.1% and 2.9% for major bleeding, 13.6%, 9.7% and 6.8% for all-cause death, and 16.2%, 12.0% and 9.5% for the composite outcome. CONCLUSION THEMIS-like prevalence was estimated at 1.50 per 1,000 adults, representing about a quarter of CAD-T2DM without MI/stroke patients, and 0.27 per 1000 adults for the THEMIS-PCI-like populations. In current French practice, the median age of both these populations was about 5-6 years older than in the THEMIS trial, with a 2-year incidence of major outcomes between two or four time above the ones of the placebo arm of the THEMIS trial using very close definitions.

Abstract
Background: Despite the prognostic effectiveness of cardiac rehabilitation (CR) in patients with cardiovascular disease (CVD), it has been underutilized. Understanding the trend of dissemination of CR over the years would help provide a perspective of CR in Japan. Methods and Results: A retrospective epidemiological survey between fiscal years 2010 and 2017 was conducted using the diagnosis procedure combination database (a Japanese administrative database). Data on 2,046,302 patients with CVD from 1,632 hospitals were extracted. The proportion of CR-certified hospitals among hospitals treating patients with CVD increased from 31.6% in 2010 to 56.6% in 2017. Over the same period, the participation rate in inpatient CR (ICR) increased from 18.3% to 39.0%, but the participation rate in outpatient CR (OCR) remained low (from 1.4% to 2.5%). The CR participation rates varied widely according to the main disease group. Approximately 95% of ICR participants did not continue CR after discharge. Conclusions: The number of CR-certified hospitals increased from 2010 to 2017, leading to increased ICR participation across patients with CVD; however, OCR has remained extremely underutilized. Immediate action is urgently required to increase the use of OCR.

Abstract
BACKGROUND Addition of a long-acting muscarinic antagonist is recommended for patients with asthma uncontrolled on inhaled corticosteroid/long-acting β2-agonist therapy. This is the first large-scale, real-world study examining multiple-inhaler triple-therapy (MITT) use in asthma. OBJECTIVE To describe real-world prevalence, outcomes, and treatment patterns associated with MITT. METHODS This retrospective cohort study used medical and pharmacy claims from the Optum Research Database. Patients were diagnosed with asthma between January 01, 2013, and July 31, 2018, with evidence of MITT use (≥1 overlapping days' supply of inhaled corticosteroid, long-acting β2-agonist, and long-acting muscarinic antagonist). Annual MITT prevalence (primary end point) was assessed in the prevalent population; eligible patients were 18 years or older with 2 or more asthma diagnoses during the study period, and continuous enrollment for the entire year. Secondary outcomes (adherence [proportion of days covered], MITT persistence, health care resource utilization, costs) were assessed in the incident MITT population; eligible patients were 18 years or older, with 2 or more asthma diagnoses and continuous enrollment during both the 12-month baseline and 12-month follow-up periods. Patients with chronic obstructive pulmonary disease or cystic fibrosis were excluded. RESULTS MITT prevalence was low but increased from 0.35% (95% CI, 0.32-0.37) in 2014/2015 to 1.00% (95% CI, 0.96-1.04) in 2017/2018. Among 1831 incident MITT users, there was a substantial disease burden, demonstrated by high health care resource utilization and exacerbation rates. Adherence and persistence to MITT was low (mean proportion of days covered, 0.31 ± 0.27), and 12% (n = 216) remained on MITT 12 months postinitiation. CONCLUSIONS Overall, MITT use among patients with asthma is low. Patients initiating MITT have substantial disease burden and significant unmet needs.

Abstract
PURPOSE Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse event of cancer treatment; however, no drug is recommended for the prevention of CIPN. In Japan, several drugs such as Gosha-Jinki-Gan and duloxetine are frequently administered as a treatment for CIPN. The aim of this study was to elucidate prescription patterns of drugs administered for CIPN caused by oxaliplatin and the association between these drugs and the duration of oxaliplatin treatment. METHODS We conducted a retrospective nationwide study using the JMDC administrative claims database (January 2005-June 2020; JMDC Inc., Japan). Patients newly treated with oxaliplatin were identified, and prescription patterns of CIPN medication including Gosha-Jinki-Gan, pregabalin, duloxetine, mecobalamin, and mirogabalin were investigated. The primary outcome was the duration of oxaliplatin treatment. Multivariable logistic regression analysis was performed to examine the association between CIPN medication and duration of oxaliplatin treatment. RESULTS A total of 4,739 patients who newly received oxaliplatin were identified. Of these, 759 (16.0%) had received CIPN medication. Duloxetine was administered in 99 (2.1%) patients. Multivariable logistic regression analysis revealed that CIPN medication was significantly associated with the prolonged duration of oxaliplatin treatment (odds ratio: 2.35, [95% confidence interval: 1.99-2.77]). CONCLUSION Real-world data demonstrated that the administration rate of CIPN medication was higher in patients who received oxaliplatin treatment for over 6 months.

Abstract
PURPOSE To investigate the association between the use of topical β-blockers and subsequent asthma attacks in glaucoma patients with asthma. METHODS This was a retrospective longitudinal cohort study using an administrative claims database. All patients aged 20 years or older who were registered in the health insurance claims database updated and managed by JMDC Inc. (Tokyo, Japan). Patients who were newly prescribed eye drops for glaucoma treatment were identified between 2011 and 2017. The patients with glaucoma were divided into two groups: β-blocker users and non-β-blocker users, based on the presence of a β-blocker in the prescribed eye drops. We investigated whether the incidence of asthma attacks in patients with previously treated asthma differed between the two groups. RESULTS We categorized 17,666 patients in the β-blocker-user group and 12,609 patients in the non-β-blocker-user group. A total of 580 patients in the β-blocker group (3.28%) and 847 in the non-β-blocker group (6.72%) underwent asthma treatment before the prescription of anti-glaucoma eye drops (P < 0.001). Furthermore, 94 patients in the β-blocker-user group (0.53%) and 278 in the non-β-blocker user group (2.20%) were undergoing current treatment for asthma (P < 0.001). The adjusted hazard ratios of asthma attacks were 0.73 (95% confidence interval, 0.46-1.16, P = 0.18) in patients with a history of asthma treatment and 1.22 (95% confidence interval, 0.56-2.70, P = 0.62) in patients with current asthma treatment, compared to the non-β-blocker-user group. CONCLUSION Our results clarified that several patients with asthma were prescribed topical β-blockers for glaucoma treatment. However, asthma attacks may not be significantly attributed to topical β-blockers, even in glaucoma patients under current asthma treatment. The administration of topical β-blockers to asthma patients could be a treatment option in the absence of other treatment options, if adequate informed consent is obtained. Further studies are needed to draw a firm conclusion on this clinical question.

Abstract
BACKGROUND The French Cancer Plan 2014-2019 had a target of 60% HPV vaccine coverage. The PAPILLON study investigated the annual age-specific vaccination initiation rates and cumulative partial and complete vaccination rates in France from 2017 to 2022. It also identified the factors associated with vaccination in different age groups and those associated with the type of completion of the vaccination scheme (partial vs full vaccination). METHODS For this publication, all females recorded in the French National Claims database who initiated HPV vaccination between 1 July 2007 and 31 December 2018 and were aged between 11 and 19 years at initiation were included. Annual HPV vaccination initiation rates were estimated in 11- to 14-year-old (target population) and 15- to 19-year-old females (catch-up). Cumulative vaccine coverage rates (VCRs) were estimated among those who were 15, 16, 20 and 21 years old. Partial vaccination was defined by dispensing of at least one dose of HPV vaccine by the pharmacy, while full vaccination was defined by two or three doses dispensed by a pharmacy over an 18-month period, according to current French recommendations based on the age at vaccination initiation. RESULTS Among the 465,629 females who initiated HPV vaccination in 2017 or 2018, the initiation rate increased from 7.7 to 11.1% in 11- to 14-year-old girls and from 4.5 to 6.5% in 15- to 19-year-old females. In 2017 and 2018, the cumulative VCRs for partial vaccination by age 15 were 28.2% and 32.8%, respectively, while by age 20, they were 41.6% and 38.8%. The cumulative VCRs for full vaccination were 15.6% and 18.6% by age 16, while they were 25.9 and 23.6% by age 20. HPV vaccination initiation and completion were strongly associated with the use of health services. CONCLUSION Overall, the HPV VCR substantively increased between 2017 and 2018, which is positive evidence of the resumption of vaccination. Updates in 2022 should confirm these results.

Abstract
PURPOSE To estimate the nationwide, longitudinal prevalence and incidence rates and assess treatment patterns of non-infectious uveitis (NIU) in Japan. STUDY DESIGN A retrospective study. METHODS Health insurance claims' data of patients with NIU were extracted from the Japan Medical Data Center (JMDC) database and analyzed descriptively (data extraction period, January 2011 to May 2017). Behçet's disease (BD), Vogt-Koyanagi-Harada (VKH) disease, and sarcoidosis were selected as the primary diseases of NIU. RESULTS From 2011 to 2016, the mean and median age of patients increased. Most (> 90%) patients were categorized as "undifferentiated NIU" (NIU without specific primary disease information after excluding BD-, VKH disease-, and sarcoidosis-associated NIU). Over 60% of patients with NIU were treated at non-hospital clinics, while the rest were treated at university, public, or other hospitals. The estimated prevalence rate of NIU was 386.5 per 100,000 persons (95% confidence interval [CI], 374.5-398.6) in 2011 and 439.3 per 100,000 persons (95% CI, 432.3-446.3) in 2016; the estimated incidence rate was 189.7 per 100,000 persons (95% CI, 181.2-198.5) in 2012 and 207.8 per 100,000 persons (95% CI, 202.2-213.5) in 2016. Most patients' prescribed uveitis drugs were ophthalmic drops over the first 6 months after patient presentation and entry into the JMDC database, followed by systemic corticosteroids. CONCLUSION The estimated prevalence of NIU in Japan in recent years was approximately 400 with incidence of 200 per 100,000 persons.

Abstract
Background Escalation to triple therapy (long-acting muscarinic antagonist/β2-agonist, inhaled corticosteroid [ICS]) in chronic obstructive pulmonary disorder (COPD) is recommended for patients on LAMA/LABA combinations with frequent exacerbations and severe symptoms. An extended time-to-escalation to triple therapy suggests patients are in a stable condition and is an indicator of treatment effectiveness. No studies in Japanese clinical practice have compared the effectiveness of LAMA/LABA fixed-dose combination therapies with LAMA monotherapy in terms of time-to-escalation to triple therapy. The primary objective of this real-world study in Japan was to compare time-to-escalation to triple therapy among new users of tiotropium/olodaterol or tiotropium monotherapy for COPD without asthma. Methods In this active-comparator cohort study, new users of tiotropium/olodaterol (n = 1436) and tiotropium monotherapy (n = 5352) were identified from a large Japanese hospital-based database (Medical Data Vision Co., Ltd., Tokyo; prespecified study period: 1 April 2015 to 31 March 2019); patients in each group were matched 1:1 using high-dimensional propensity scores (hdPS). The primary outcome was time-to-escalation to triple therapy. Results For the prespecified study period in the hdPS-matched cohort, escalation to triple therapy was infrequent among new users of tiotropium/olodaterol (n = 1302, 7 escalation events) and tiotropium monotherapy (n = 1302, 8 escalation events). The difference in time-to-escalation to triple therapy between groups was not statistically significant (median [interquartile range]: 28 days [15.0–139.2] for tiotropium monotherapy vs 193 days [94.5–302.0] for tiotropium/olodaterol; hazard ratio: 0.89; 95% CI: 0.32–2.46). Similar findings (hazard ratio: 0.71; 95% Cl: 0.36–1.40) were observed in a post hoc analysis, which extended the study period by 1 year to 31 March 2020. Risks of first moderate and/or severe COPD exacerbation were lower for tiotropium/olodaterol than tiotropium monotherapy (between-group differences not significant). There were no significant between-group differences for the risks of all-cause inpatient mortality, major adverse cardiovascular events, and first use of home oxygen therapy. Conclusions ICS monotherapy or ICS/LABA added to tiotropium or tiotropium/olodaterol is limited in Japanese clinical settings. The number of escalations to triple therapy was very limited in the dataset and there was insufficient power to detect differences between the treatment groups in the primary hdPS-matched cohort.

Abstract
INTRODUCTION Precision medicine technologies have significant impact in the care of patients with ovarian cancer. Compared to affluent patients, socioeconomically vulnerable patients are less likely to have access to this testing. There is little data that demonstrate this inequity over time. METHODS We used the IBM Truven Health MarketScan Research Database to identify patients in the United States who underwent surgery for ovarian cancer between 2011 and 2017. The presence of claims for precision medicine testing within six months of surgery was assessed for each patient. Precision medicine testing included both molecular genetic testing (BRCA limited or full sequencing, somatic and germline testing) as well as ancillary pathology tests (immunohistochemistry, microsatellite instability). Demographic data was extracted. RESULTS We identified 27,181 patients who met eligibility. Of these, 88.6% had commercial insurance, and 11.4% had Medicaid. While the proportion of patients who underwent precision medicine testing increased over time for both cohorts (47.0% to 66.6% for commercially insured, 41.4% to 57.6% for Medicaid insured, p < 0.0001), the inequity in testing rates widened (5.6% disparity to 9.0%, p < 0.0001). This was driven by growing inequity in germline and somatic genetic testing (7.6% disparity to 21.3%, p < 0.0001). CONCLUSIONS There is widening inequity in precision medicine testing rates between commercially insured and Medicaid insured poate patients with ovarian cancer.
