Abstract
AIM Behavioral and psychological symptoms and delirium frequently occur in hospitalized older patients with pneumonia and are associated with longer hospital stays. Yokukan-San (YKS, traditional Japanese [Kampo] medicine) and antipsychotics are often used to treat delirium and behavioral and psychological symptoms in Japan. Hence, this study aimed to assess the effectiveness and safety of the co-administration of YKS with atypical antipsychotics in older patients with pneumonia. METHODS We used the Japanese Diagnosis Procedure Combination inpatient database to retrospectively identify older patients (≥65 years) hospitalized for pneumonia who received antipsychotics within 3 days of hospitalization. The patients were divided into two groups: those who received atypical antipsychotics alone (control group) and those who received both atypical antipsychotics and YKS (YKS group). We compared length of hospital stay, in-hospital mortality, bone fractures, and administration of potassium products between the two groups using propensity score overlap weighting. RESULT We identified 4789 patients in the YKS group and 61 641 in the control group. After propensity score overlap weighting, length of hospital stay was statistically significantly shorter in the YKS group (percentage difference -3.0%; 95% confidence interval -5.8% to -0.3%). The proportion of patients who received potassium products was higher in the YKS group (odds ratio 1.34; 95% confidence interval 1.15-1.55). In-hospital death and bone fractures were not significantly different. CONCLUSION Co-administration of YKS with atypical antipsychotics could be a reasonable treatment option for hospitalized older patients with pneumonia and aggressive psychiatric symptoms.

[PMID: 37540262 PMCID: PMC10576683 DOI: 10.1007/s00262-023-03508-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 07/23/2023] [Indexed: 08/05/2023]
Abstract
OBJECTIVES To determine the associated thromboembolism risk with adding immune checkpoint inhibitors (ICI) to platinum combination chemotherapy compared with platinum combination chemotherapy alone in patients with advanced non-small cell lung cancer. MATERIALS AND METHODS This study identified 75,807 patients with advanced non-small cell lung cancer from the Japanese Diagnosis Procedure Combination database who started platinum combination chemotherapy between July 2010 and March 2021. The incidence of venous thromboembolism (VTE), arterial thromboembolism (ATE), and all-cause mortality within 6 months after commencing platinum combination chemotherapy was compared between patients receiving chemotherapy with ICI (ICI group, n = 7,177) and without ICI (non-ICI group, n = 37,903). Survival time analysis was performed using the overlap weighting method with propensity scores to adjust for background factors. The subdistribution hazard ratio for developing thromboembolism was calculated using the Fine-Gray model with death as a competing risk. The hazard ratio for all-cause mortality was also calculated using the Cox proportional hazards model. RESULTS Overall, VTE and ATE occurred in 761 (1.0%) and 389 (0.51%) patients, respectively; mortality was 11.7%. Propensity score overlap weighting demonstrated that the subdistribution hazard ratio (95% confidence interval) for VTE and ATE in the ICI group was 1.27 (1.01-1.60) and 0.96 (0.67-1.36), respectively, compared with the non-ICI group. The mortality hazard ratio in the ICI group was 0.68 (0.62-0.74). CONCLUSION The addition of ICI to platinum combination therapy was associated with a higher risk of VTE compared with platinum combination therapy alone, while the risk of ATE might be comparable.

Abstract
The aim of this study was to compare in-hospital mortality of three procedures -halo-vest immobilization, anterior spinal fixation (ASF), and posterior spinal fixation (PSF)- in the treatment of elderly patients with isolated C2 odontoid fracture. We extracted data for elderly patients who were admitted with C2 odontoid fracture and treated with at least one of the three procedures (halo-vest immobilization, ASF, or PSF) during hospitalization. We conducted a generalized propensity score-based matching weight analysis to compare in-hospital mortality among the three procedures. We further investigated independent risk factors for in-hospital death. The study involved 891 patients (halo-vest, n = 463; ASF, n = 74; and PSF, n = 354) with a mean age of 78 years. In-hospital death occurred in 45 (5.1%) patients. Treatment type was not significantly associated with in-hospital mortality. Male sex (odds ratio 2.98; 95% confidence interval 1.32-6.73; p = 0.009) and a Charlson comorbidity index of ≥ 3 (odds ratio 9.18; 95% confidence interval 3.25-25.92; p < 0.001) were independent risk factors for in-hospital mortality. In conclusion, treatment type was not significantly associated with in-hospital mortality in elderly patients with isolated C2 odontoid fracture. Halo-vest immobilization can help to avoid adverse events in patients with C2 odontoid fracture who are considered less suitable for surgical treatment.

Abstract
BACKGROUND Previous studies have reported conflicting results regarding fresh frozen plasma (FFP)-to-red blood cell (RBC) ratio and platelet-to-RBC ratio on outcomes for massive transfusion for trauma. Moreover, nationwide data on massive transfusion practices for trauma in the real-world clinical setting are scarce. This study aimed to examine the nationwide practice patterns and trends in massive transfusion for trauma in Japan using a national administrative, inpatient database. METHOD We identified patients who underwent emergency hospitalization for trauma and received massive transfusion, defined as administration of at least 20 units of RBC within the first 2 days of admission, using the nationwide inpatient database, which covers approximately 90% of all tertiary emergency hospitals in Japan, between 2011 and 2020. Trends in the incidence and practice patterns of massive transfusion were described by calendar year. The association of practice patterns with mortality or adverse events was tested. RESULTS A total of 3,530,846 trauma hospitalizations were identified, of which 5247 (0.15%) received massive transfusion. A significant declining trend was observed in the incidence of massive transfusion in trauma hospitalizations from 0.24% in 2011 to 0.10% in 2020 (P for trend < 0.001). The FFP-to-RBC ratio rose significantly from 0.77 in 2011 to 1.08 in 2020 (P for trend < 0.001), while the platelet-to-RBC ratio remained virtually unchanged from 0.71 in 2011 to 0.78 in 2020 (P for trend 0.060). Massive transfusion with lower FFP-to-RBC (< 0.75) and platelets-to-RBC ratio (< 1.00) were associated with increased in-hospital mortality compared with those ≥ 1.00, while there were linear increases in adverse events with increasing FFP and platelets ratios. CONCLUSIONS This study demonstrated a declining trend in the incidence and a rise in higher FFP-to-RBC ratios in massive transfusion in association with patient outcomes for trauma from 2011 to 2020 in Japan.

Abstract
BACKGROUND The prognosis for acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is poor, and there is no established treatment. Hence, we aimed to investigate the effectiveness of a polymyxin B-immobilised fibre column (PMX) for the treatment of AE-IPF. METHODS Data were retrospectively collected from the Japanese Diagnosis Procedure Combination database from 1 July 2010 to 31 March 2018. We identified adult patients with idiopathic pulmonary fibrosis who received high-dose methylprednisolone (mPSL) therapy and mechanical ventilation upon admission. Eligible patients (n = 5616) were divided into those receiving PMX treatment combined with high-dose mPSL (PMX group, n = 199) and high-dose mPSL alone (mPSL alone group, n = 5417). To compare outcomes between the two groups, we applied a stabilised inverse probability of treatment weighting (IPTW) using propensity scores. The primary outcome was in-hospital mortality, and the secondary outcomes were 14- and 28-day mortality and length of hospital stay. RESULTS The in-hospital mortality rates of the PMX and mPSL alone groups were 79.9% and 76.4%, respectively. The results did not significantly differ between the two groups after performing a stabilised IPTW. The odds ratio of the PMX group compared with the mPSL alone group was 1.56 (95% confidence interval 0.80-3.06; p = 0.19). The 14- and 28-day mortality and length of hospital stay (secondary outcomes) also did not significantly differ between the two groups. CONCLUSIONS In AE-IPF patients using mechanical ventilation, the treatment outcome was not significantly better for PMX combined with high-dose mPSL than for high-dose mPSL alone.

Gemcitabine plus nab-paclitaxel for pancreatic cancer and interstitial lung disease: A nationwide longitudinal study. Cancer Sci 2023; 114:3996-4005. [PMID: 37547944 PMCID: PMC10551588 DOI: 10.1111/cas.15910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 06/30/2023] [Accepted: 07/09/2023] [Indexed: 08/08/2023] Open
Abstract
Interstitial lung disease (ILD) is an adverse event associated with gemcitabine administration. Gemcitabine plus nab-paclitaxel, which is now a first-line chemotherapy regimen for pancreatic cancer (PC), may increase the risk of ILD; however, large-scale clinical data on this are limited. Thus, this study aimed to elucidate the incidence and risk factors of ILD in patients with PC receiving gemcitabine plus nab-paclitaxel. Through the Diagnosis Procedure Combination database, a Japanese nationwide inpatient database with outpatient data, we identified consecutive patients with PC who received gemcitabine-based chemotherapy between July 2010 and March 2019 at 205 hospitals. Competing-risk analysis was used to examine the cumulative incidence and risk factors of ILD. Among the 6163 patients who received gemcitabine plus nab-paclitaxel, we documented 168 patients (2.7%) who developed ILD with cumulative incidence rates (95% confidence intervals [CIs]) of 2.0% (1.6%-2.4%), 2.7% (2.2%-3.1%), and 3.1% (2.6%-3.6%) at 3, 6, and 12 months, respectively. Compared with patients with PC who received gemcitabine monotherapy, those who received gemcitabine plus nab-paclitaxel had an adjusted subdistribution hazard ratio (SHR) for ILD of 1.93 (95% CI: 1.51-2.47). Older age was associated with a high risk of ILD in patients receiving gemcitabine plus nab-paclitaxel (adjusted SHR comparing ≥75 to ≤74 years, 1.61; 95% CI: 1.16-2.24). In conclusion, this study demonstrated the clinical course of gemcitabine plus nab-paclitaxel-associated ILD in patients with PC. When gemcitabine plus nab-paclitaxel is administered to elderly patients with PC, symptoms associated with ILD must be monitored.

Proportion of early extubation and short-term outcomes after esophagectomy: a retrospective cohort study. Int J Surg 2023; 109:3097-3106. [PMID: 37352519 PMCID: PMC10583926 DOI: 10.1097/js9.0000000000000568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 06/11/2023] [Indexed: 06/25/2023]
Abstract
BACKGROUND The proportion of early extubation after esophagectomy varies among hospitals; however, the impact on clinical outcomes is unclear. The aim of this retrospective study was to evaluate associations between the proportion of early extubation in hospitals and short-term outcomes after esophagectomy. Because there is no consensus regarding the optimal timing for extubation, the authors considered that hospitals' early extubation proportion reflects the hospital-level extubation strategy. MATERIALS AND METHODS Data of patients who underwent oncologic esophagectomy (July 2010-March 2019) were extracted from a Japanese nationwide inpatient database. The proportion of patients who underwent early extubation (extubation on the day of surgery) at each hospital was assessed and grouped by quartiles: very low- (<11%), low- (11-37%), medium- (38-83%), and high-proportion (≥84%) hospitals. The primary outcome was respiratory complications; secondary outcomes included reintubation, anastomotic leakage, other major complications, and hospitalization costs. Multivariable regression analyses were performed, adjusting for patient demographics, cancer treatments, and hospital characteristics. A restricted cubic spline analysis was also performed for the primary outcome. RESULTS Among 37 983 eligible patients across 545 hospitals, early extubation was performed in 17 931 (47%) patients. Early extubation proportions ranged from 0-100% across hospitals. Respiratory complications occurred in 10 270 patients (27%). Multivariable regression analyses showed that high- and medium-proportion hospitals were significantly associated with decreased respiratory complications [odds ratio, 0.46 (95% CI, 0.36-0.58) and 0.43 (0.31-0.60), respectively], reintubation, and hospitalization costs when compared with very low-proportion hospitals. The risk of anastomotic leakage and other major complications did not differ among groups. The restricted cubic spline analysis demonstrated a significant inverse dose-dependent association between the early extubation proportion and the risk of respiratory complications. CONCLUSION A higher proportion of early extubation in a hospital was associated with a lower occurrence of respiratory complications, highlighting a potential benefit of early extubation after esophagectomy.

Abstract
BACKGROUND The association between health behaviors and the risk of developing hypertension and diabetes is not fully understood. We aimed to examine the association between four health behaviors involved in Life's Essential 8, the American Heart Association's key measures for improving and maintaining cardiovascular health, and the incidence of hypertension and diabetes. METHODS This observational cohort study used the JMDC Claims Database between 2005 and 2021, which is a health check-up and claims database. We analyzed 2,912,183 participants without a history of hypertension, diabetes, cardiovascular disease, or renal failure. Non-ideal health behaviors included smoking, slow gait speed, eating fast, and poor sleep quality. RESULTS During 1140 ± 877 days, 201,385 hypertension and 142,156 diabetes events were recorded. In a multivariable Cox regression analysis, the risk of hypertension and diabetes increased with an increasing number of non-ideal health behaviors. The hazard ratios (HRs) (95% confidence interval [CI]) per 1-point increase in non-ideal health behavior components for hypertension and diabetes were 1.11 (1.10-1.11) and 1.08 (1.08-1.09), respectively. Each health behavior was independently associated with the incidence of hypertension and diabetes. A 1-point improvement in health behaviors was associated with a lower risk of developing hypertension (HR 0.94, 95% CI 0.93-0.95) and diabetes (HR 0.95, 95% CI 0.94-0.96). CONCLUSION Factors that can be substituted for the four health behaviors involved in Life's Essential 8 can stratify the risk of hypertension and diabetes, and improving these health behaviors is useful in preventing hypertension and diabetes in general population.

Abstract
BACKGROUND AND AIMS EUS-guided interventions currently serve as first-line treatment for symptomatic pancreatic fluid collections (PFCs) but require high-level expertise and multidisciplinary care. Hospital caseload has not been fully examined in relation to clinical outcomes of patients with endoscopically managed PFCs. METHODS Using the Diagnosis Procedure Combination database (a Japanese nationwide inpatient database), we identified 4053 patients receiving EUS-guided treatment of PFCs at 486 hospitals between 2010 and 2020 and examined an association of hospital volume (average annual number of cases at a hospital) with in-hospital mortality. Associations with bleeding, length of stay, and total costs were examined as secondary analyses. Multivariable logistic regression analysis was conducted with adjustment for potential confounders. RESULTS The hospital volume was inversely associated with the risk of in-hospital mortality (Ptrend < .001). The adjusted odds ratio for in-hospital mortality comparing the extreme quintiles of hospital volume was .17 (95% confidence interval, .09-.33). A restricted cubic spline analysis yielded no statistically significant evidence on the nonlinear relationship (Pnonlinearity = .19). The types of stents (plastic vs lumen-apposing metal stent) seemed to have no effect modification on the volume-mortality relationship (Pinteraction = .58). Higher hospital volume was also associated with lower risk of bleeding, shorter length of stay, and lower medical costs of inpatient care. CONCLUSIONS Higher hospital volume was associated with a lower risk of in-hospital mortality of patients receiving EUS-guided treatment of PFCs. A further investigation is warranted to justify the volume-based selective referral of the patients.

Abstract
BACKGROUND Bronchial thermoplasty (BT) has been shown to be effective in randomized controlled trials of patients with severe asthma who failed to achieve disease control with high-dose inhaled corticosteroids combined with bronchodilators. However, the effectiveness of BT in real-world clinical settings, especially among the Asian population, has not been determined. OBJECTIVE To evaluate the effectiveness of BT using a nationwide database. METHODS Using the inpatient and outpatient data from the Japanese Diagnosis Procedure Combination database, we applied a self-controlled case series design to evaluate changes in the composite outcome of hospital admissions and emergency department visits, as well as systemic corticosteroid dose, between 1 year before and after BT. We also conducted subgroup analyses based on patients' profiles. RESULTS Among the 561 patients with asthma who underwent BT treatment between September 2014 and March 2020, 102 patients with at least 1 outcome were analyzed. Bronchial thermoplasty was significantly associated with an improvement in the composite outcome of hospital admission and emergency department visits (incidence rate ratio 0.53; 95% CI 0.44-0.64). Systemic corticosteroid use was reduced after BT sessions (1931.5 mg [1,341.2-3,725.3 mg] to 641.3 mg [134.2-1,691.1 mg] per person-year; P < .001). Although all groups showed a significant improvement in the composite outcome in the subgroup analyses, BT tended to be less effective among people older than 65 years and those with higher body mass index (>25 kg/m2). CONCLUSIONS The present study using real-world data suggests that BT may improve asthma control; however, the effectiveness of BT can vary depending on patient baseline profiles.

Abstract
INTRODUCTION Milrinone is administered after patent ductus arteriosus (PDA) ligation to prevent and treat postoperative hemodynamic instability (i.e., postligation cardiac syndrome). We aimed to explore the effectiveness of milrinone on in-hospital outcomes in infants who underwent PDA ligation using a nationwide inpatient database in Japan. METHODS Using the Japanese Diagnosis Procedure Combination database, we identified patients who received milrinone after PDA ligation (n = 428) in neonatal intensive care units between July 2010 and March 2021 and those who did not (n = 3,392). We conducted a 1:4 propensity score-matched analysis with adjustment for background characteristics (e.g., gestational age, birth weight, comorbidities, preoperative treatments, and hospital background) to compare morbidities (bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and retinopathy of prematurity), mortality, total hospitalization costs, and other outcomes. For sensitivity analysis, we performed an overlap propensity score-weighted analysis. RESULTS In-hospital morbidity, bronchopulmonary dysplasia, intraventricular hemorrhage, and necrotizing enterocolitis occurred in 58%, 48%, 9.5%, and 7.1% of patients, respectively; the in-hospital mortality was 5.4%. After 1:4 propensity score matching, no significant difference was observed regarding mortality (7.1 vs. 5.7%), in-hospital morbidity (55 vs. 50%), bronchopulmonary dysplasia (44 vs. 41%), intraventricular hemorrhage (7.8 vs. 9.1%), necrotizing enterocolitis (8.5 vs. 8.9%), retinopathy of prematurity (21 vs. 22%), or total hospitalization costs (median: approximately 86,000 vs. 82,000 US dollars) between milrinone users (n = 425) and nonusers (n = 1,698). Sensitivity analyses yielded consistent results. CONCLUSIONS Milrinone use after PDA ligation was not associated with improved in-hospital outcomes, such as mortality and morbidity.

[PMID: 37746980 PMCID: PMC10519481 DOI: 10.1097/md.0000000000035032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 08/04/2023] [Accepted: 08/10/2023] [Indexed: 09/26/2023] Open
Abstract
Transdermal tulobuterol, a long-acting beta agonist in a transdermal form, is available in some countries, including Japan, Korea, and China. It may provide an alternative treatment option for the management of chronic obstructive pulmonary disease (COPD) in patients who are unable to effectively use inhalers, such as those with acute stroke. This study examined the short-term outcomes of transdermal tulobuterol in patients hospitalized with acute stroke and underlying COPD. Using the Diagnosis Procedure Combination database, a national inpatient database in Japan, we identified patients with stroke and underlying COPD who were hospitalized between July 2010 and March 2021. We performed propensity-score overlap weighting to compare in-hospital death, COPD exacerbation, pneumonia, and cardiac complications between patients who initiated transdermal tulobuterol within 2 days of admission and those who did not use it during hospitalization. Of the 1878 eligible patients, 189 received transdermal tulobuterol within 2 days of admission. After adjusting for baseline variables, transdermal tulobuterol was not associated with a reduction in in-hospital death (18.3% vs 16.1%; odds ratio, 1.17; 95% confidence interval, 0.72-1.90). Additionally, we observed no significant difference in COPD exacerbation, pneumonia, and cardiac complications between both groups. Transdermal tulobuterol was not associated with improving short-term outcomes in patients with acute stroke and underlying COPD. Our study does not support the routine use of transdermal tulobuterol in this patient group. However, further research investigating the long-term efficacy of transdermal tulobuterol in patients with stroke and underlying COPD could help establish its role for the management of these patients.

Impact of a financial incentive scheme for team-based palliative care in patients with heart failure in Japan: A nationwide database study. Int J Cardiol 2023; 387:131145. [PMID: 37364713 DOI: 10.1016/j.ijcard.2023.131145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 06/05/2023] [Accepted: 06/23/2023] [Indexed: 06/28/2023]
Abstract
BACKGROUND Palliative care provided to patients with heart failure (HF) are reported to be inadequate. Herein, we examined the impact of the recently introduced financial incentive scheme for team-based palliative care for patients with HF in acute care hospitals in Japan. METHODS Using a nationwide inpatient database, we identified patients aged ≥65 years with HF who had died between April 2015 and March 2021. Interrupted time-series analyses were used to compare practice patterns in end-of-life care (symptom management and invasive medical procedures within one week before death) before and after the financial incentive scheme issuance in April 2018. RESULTS Overall, 53,857 patients in 835 hospitals were eligible. The adoption of the financial incentive was 1.10 to 1.22% after the introduction. There were upward pre-trends in opioid use (+0.11% per month; 95% confidence interval [CI], 0.06 to 0.15) and antidepressant use (+0.06% per month; 95% CI, 0.04 to 0.09). Opioid use showed a downward slope change during the post-period (-0.07% change in trend; 95% CI, -0.13 to -0.01). Intensive care unit stay showed a downward pre-trend (-0.09% per month; 95% CI, -0.14 to -0.04) and upward slope changes during the post-period (+0.12% change in trend; 95% CI, 0.04 to 0.19). Invasive mechanical ventilation showed downward slope changes during the post-period (-0.11% change in trend; 95% CI, -0.18 to -0.04). CONCLUSIONS The financial incentive scheme for team-based palliative care was rarely adopted and not associated with changes in end-of-life care. Further multifaceted strategies to promote palliative care for HF are warranted.

Abstract
Little is known about the impact of the downgrade of guideline recommendations for intra-aortic balloon pump (IABP) use and the approval of the Impella in Japan, where IABPs have been predominantly used. This study aimed to describe the annual trends in the mechanical circulatory support (MCS) use and outcomes in patients with cardiogenic shock (CS) requiring MCS. Using the Japanese Diagnosis Procedure Combination database from July 2010 to March 2021, we identified inpatients with CS requiring MCS. The patients were stratified into 3 groups: (1) IABP alone, (2) Impella alone, and (3) extracorporeal membrane oxygenation (ECMO), regardless of IABP or Impella use. The patient characteristics and outcomes were reported by the fiscal year. Of the 160,559 eligible patients, 117,599 (73.2%) used IABP alone, 1,465 (0.9%) Impella alone, and 41,495 (25.8%) ECMO. The prevalence of the use of an IABP alone significantly decreased from 80.5% in 2010 to 65.3% in 2020 (p for trend <0.001), whereas the prevalence of the use of an Impella alone significantly increased from 0.0% to 5.0% and ECMO from 19.5% to 29.6% (p for trend <0.001 for both). In-hospital mortality significantly increased from 29.3% in 2010 to 32.6% in 2020 in the overall patients with CS requiring MCS but significantly decreased in those requiring ECMO from 73.7% to 64.1% (p for trend <0.001 for both). In conclusion, there were significant annual changes in the patterns of MCS use and clinical outcomes in patients with CS requiring MCS.

Abstract
PURPOSE To investigate the association between annual hospital volume of endovascular therapy (EVT) and long-term outcomes in patients with lower-extremity peripheral artery disease (PAD). MATERIALS AND METHODS We identified patients who underwent percutaneous endovascular transluminal angioplasty and thrombectomy of the extremities or percutaneous endovascular removal in the Japanese Diagnosis Procedure Combination inpatient database from April 2014 to March 2020 linked to the Survey of Medical Institutions data. A generalized linear model analysis was performed to assess 12-month amputation, all-cause death, composite outcome (amputation and death), and readmission. We also analyzed length of hospital stay and total health care costs during the first hospitalization. RESULTS Among 127 486 eligible patients, 31 579, 31 913, 31 999, and 31 995 were in the first (1-27 cases/year), second (28-44 cases), third (45-67 cases), and fourth (68-289 cases) quartiles, respectively. There were no significant differences in 12-month amputation among the second (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.90-1.04), third (OR, 1.00; 95% CI, 0.93-1.07), and fourth (OR, 1.00; 95% CI, 0.93-1.07) quartile volumes compared with the first quartile. Significant differences were observed in 12-month death (OR for fourth quartile with reference to the first quartile, 0.71; 95% CI, 0.65-0.76), composite outcome (OR, 0.84; 95% CI, 0.80-0.89), and readmission (OR, 1.05; 95% CI, 1.02-1.09). CONCLUSIONS We found that the annual hospital volume of EVT was not associated with decreased 12-month amputation in patients with lower-extremity PAD. In contrast, all-cause death and composite outcome were significantly decreased in hospitals with the highest volume. CLINICAL IMPACT The association between hospital volume of endovascular therapy and long-term adverse clinical outcomes remains unclear. The present analyses showed no significant differences in 12-month amputation rates among the hospital volumes, whereas higher-volume quartiles were significantly associated with decreased 12-month all-cause death rates and composite outcome. There was also a positive association in the length of stay between the first quartile volume and the others, while no significant difference in total health care costs among the quartiles was observed. Further investigations are needed, including insights into operator volume and procedural characteristics, to clarify the relationship between hospital volume and long-term adverse outcomes.

Abstract
OBJECTIVES To assess the association between levels of intensive care and in-hospital mortality in patients hospitalized for sepsis, stratified by Sequential Organ Failure Assessment (SOFA) score at admission. DESIGN A nationwide, propensity score-matched, retrospective cohort study. SETTING A Japanese national inpatient database with data on 70-75% of all ICU and high-dependency care unit (HDU) beds in Japan. PATIENTS Adult patients hospitalized for sepsis with SOFA scores greater than or equal to 2 on their day of admission between April 1, 2018, and March 31, 2021, were recruited. Propensity score matching was performed to compare in-hospital mortality, and patients were stratified into 10 groups according to SOFA scores. INTERVENTIONS Two exposure and control groups according to treatment unit on day of admission: 1) ICU + HDU versus general ward and 2) ICU versus HDU. MEASUREMENTS AND MAIN RESULTS Of 97,070 patients, 19,770 (20.4%), 23,066 (23.8%), and 54,234 (55.9%) were treated in ICU, HDU, and general ward, respectively. After propensity score matching, the ICU + HDU group had significantly lower in-hospital mortality than the general ward group, among cohorts with SOFA scores greater than or equal to 6. There were no significant differences in in-hospital mortality among cohorts with SOFA scores 3-5. The ICU + HDU group had significantly higher in-hospital mortality than the general ward among cohorts with SOFA scores of 2. The ICU group had lower in-hospital mortality than the HDU group among cohorts with SOFA scores greater than or equal to 12. There were no significant differences in in-hospital mortality among cohorts with SOFA scores 5-11. The ICU group had significantly higher in-hospital mortality than the general ward group among cohorts with SOFA scores less than or equal to 4. CONCLUSIONS Patients hospitalized for sepsis with SOFA scores greater than or equal to 6 in the ICU or HDU had lower in-hospital mortality than those in the general ward, as did those with SOFA scores greater than or equal to 12 in the ICU versus HDU.

Abstract
PURPOSE Understanding the practice patterns and costs of glaucoma care in real-world clinical settings is important for optimizing medical expenses. However, glaucoma treatment trends and associated costs in Japan are unknown. We aimed to unveil glaucoma treatment trends and costs using a large administrative claims database in Japan. STUDY DESIGN Retrospective cohort study. METHODS We included patients diagnosed with glaucoma between April 2014 and March 2021 using the DeSC database. We calculated the frequencies and costs of antiglaucoma eyedrops, incisional or laser procedures, and ophthalmic examinations stratified by fiscal year and age. In the year-by-year analyses, the age distribution was standardized based on the 2020 distribution. RESULTS A total of 841,747 patient-years (429,051 patients) were included. The number of prescribed eyedrops significantly increased and the fixed-combination eyedrops proportion decreased with age. Trabeculectomy frequency decreased, and that of laser trabeculoplasty increased during the observation period. The frequencies of both incisional and laser procedures peaked in the 75-79 age group. In 2020, 16.1 bottles of eyedrops per patient-year were prescribed, and 15.9 incisional surgeries and 11.3 laser therapies were performed per 1000 patient-years. Intraocular pressure measurement and visual field testing were performed 6.5 times and 2.0 times per patient-year, respectively. The total direct cost of glaucoma treatment was 55,139 yen (US $399.5) per patient-year, of which medications accounted for 44.2%, ophthalmic examinations for 47.4%, and incisional or laser procedures for 8.4%. CONCLUSION These results may be useful for understanding glaucoma treatment trends and costs in Japan.

Abstract
INTRODUCTION The association between the use of cilostazol as a post-stroke antiplatelet medication and a reduction in post-stroke pneumonia has been suggested. However, whether cilostazol has a greater preventive effect against post-stroke aspiration pneumonia (AP) than other antiplatelet medications remains unclear. Thus, this study aimed to evaluate whether cilostazol has a greater preventive effect against post-stroke AP than aspirin or clopidogrel. METHODS Through the Japanese Diagnosis Procedure Combination database, we identified patients who were hospitalized for ischemic stroke between April 2012 and September 2019. We performed 1:1 propensity score matching between patients who received cilostazol alone at discharge and those who received aspirin or clopidogrel alone at discharge. The primary outcome was the 90-day readmission for post-stroke AP. The occurrence of recurrent ischemic stroke within 90 days was also evaluated. RESULTS Among the 305,543 eligible patients with ischemic stroke, 65,141 (21%), 104,157 (34%), and 136,245 (45%) received cilostazol, aspirin, and clopidogrel, respectively. Propensity score matching generated 65,125 pairs. The cilostazol group had a higher proportion of 90-day post-stroke readmissions with AP than the aspirin or clopidogrel groups (1.5% vs. 1.2%, p < 0.001). The proportion of patients with recurrent ischemic stroke within 90 days was also higher in the cilostazol group (2.4% vs. 2.2%, p = 0.017). CONCLUSION The present study suggests that cilostazol may not have a greater effect on preventing post-stroke AP within 90 days than other antiplatelet medications. Nevertheless, further randomized controlled trials with longer follow-up periods are warranted.

Abstract
BACKGROUND Although functional outcomes are important in surgery for elderly patients, the long-term functional prognosis following oncologic surgery is unclear. We retrospectively investigated the long-term, functional and survival prognosis following major oncologic surgery according to age among elderly patients. METHODS We used a Japanese administrative database to identify 11,896 patients aged ≥ 65 years who underwent major oncological surgery between June 2014 and February 2019. We investigated the association between age at surgery and the postoperative incidence of bedridden status and mortality. Using the Fine-Gray model and restricted cubic spline functions, we conducted a multivariable, survival analysis with adjustments for patient background characteristics and treatment courses to estimate hazard ratios for the outcomes. RESULTS During a median follow-up of 588 (interquartile range, 267-997) days, 657 patients (5.5%) became bedridden and 1540 (13%) died. Patients aged ≥ 70 years had a significantly higher incidence of being bedridden than those aged 65-69 years; the subdistribution hazard ratios of the age groups of 70-74, 75-79, 80-84, and ≥ 85 years were 3.20 (95% confidence interval [CI], 1.53-6.71), 3.86 (95% CI 1.89-7.89), 6.26 (95% CI 3.06-12.8), and 8.60 (95% CI 4.19-17.7), respectively. Restricted cubic spline analysis demonstrated an increase in the incidence of bedridden status in patients aged ≥ 65 years, whereas mortality increased in patients aged ≥ 75 years. CONCLUSIONS This large-scale, observational study revealed that older age at oncological surgery was associated with poorer functional outcomes and higher mortality among patients aged ≥ 65 years.

Abstract
BACKGROUND Mechanical circulatory support (MCS) is a common treatment modality for circulatory failure caused by pediatric myocarditis. Despite improvements in treatment strategy, the mortality rate of pediatric patients with myocarditis treated with MCS is still high. Identifying the factors associated with mortality among pediatric patients with myocarditis treated with MCS may help reduce the mortality rate. METHODS This retrospective cohort study examined the data of patients aged <16 years who were admitted to a hospital between July 2010 and March 2018 for myocarditis; the data were collected from the Diagnosis Procedure Combination database, which is a national inpatient database in Japan. RESULTS During the study period, 105 of the 598 patients with myocarditis were treated with MCS. We excluded seven patients who died within 24 h of admission, resulting in 98 eligible patients. The overall in-hospital mortality was 22 %. In-hospital mortality was higher among patients aged <2 years and those who received cardiopulmonary resuscitation (CPR). Multivariable logistic regression analysis showed significantly higher in-hospital mortality among patients aged <2 years old [odds ratio (OR), 6.57; 95 % confidence interval (CI), 1.89-22.87] and those who received CPR (OR, 4.70; 95 % CI, 1.51-14.63; p < 0.01). CONCLUSION The in-hospital mortality of pediatric patients with myocarditis treated with MCS was high, particularly of children younger than 2 years and those who received CPR.

Abstract
AIMS We aimed to explore the association between short-term exposure to temperature variability (TV), and cardiovascular hospitalization stratified by the presence of comorbid diabetes. METHODS We collected data on nationwide hospitalization for cardiovascular diseases and daily weather conditions during 2011-2018 in Japan. TV was calculated as the standard deviation of daily minimum and maximum temperatures within 0-7 lag days. We applied a two-stage time-stratified case-crossover design to estimate the association between TV and cardiovascular hospitalization with and without comorbid diabetes, adjusting for temperature and relative humidity. Furthermore, specific cardiovascular disease causes, demographic characteristics, and seasons were used for stratification. RESULTS In 3,844,910 hospitalizations for cardiovascular disease, each 1 °C increase in TV was associated with a 0.44% (95% CI: 0.22%, 0.65%) increase in the risk of cardiovascular admission. We observed a 2.07% (95% CI: 1.16%, 2.99%) and 0.61% (95% CI: -0.02%, 1.23%) increase per 1 °C in risk of heart failure admission in individuals with and those without diabetes, respectively. The higher risk among individuals with diabetes was mostly consistent in the analyses stratified by age, sex, body mass index, smoking status, and season. CONCLUSION Comorbid diabetes may increase susceptibility to TV in relation to acute cardiovascular disease hospitalization.

Abstract
AIMS Isolated diastolic hypertension (IDH) is a largely underrated risk factor for cardiovascular disease (CVD). It is currently unclear whether a reduction in blood pressure (BP) is associated with CVD events among adults with IDH. We aimed to elucidate the relationship between BP reduction and incident CVD in individuals with IDH. METHODS AND RESULTS We retrospectively analysed the data of 71 297 individuals with IDH. Isolated diastolic hypertension was defined as systolic BP of < 140 mmHg and diastolic BP (DBP) of ≥90 mmHg (median age, 48 years; 83.1% men; median DBP, 92 mmHg). None of the participants took BP-lowering medications or had a history of CVD at baseline. Blood pressure was measured at baseline and 1-year follow-up, and participants were categorized into two groups based on DBP at 1 year (≥90 or < 90 mmHg). The primary outcome was a composite endpoint that included myocardial infarction, stroke, and all-cause death. Over a mean follow-up period of 1100 ± 859 days, 1317 composite CVD endpoints were recorded. Participants with DBP of < 90 mmHg at 1 year were at a lower risk of composite CVD events [hazard ratio (HR): 0.75, 95% confidence interval (CI): 0.67-0.83] than those with DBP of ≥90 mmHg at 1 year. A reduction in DBP per 5 mmHg during the 1-year follow-up was associated with a lower composite CVD event risk (HR: 0.92, 95% CI: 0.89-0.95). The results remained consistent across a multitude of sensitivity analyses. CONCLUSION Our analysis of a large-scale epidemiological dataset demonstrated a relationship of reduction in DBP with a reduced risk for CVD events in individuals with IDH.

Abstract
OBJECTIVES Critically ill patients often have residual functional disabilities. Studies have shown that early rehabilitation improves short-term physical function. However, it remains unknown whether early rehabilitation affects long-term prognosis and healthcare resource utilization. DESIGN Retrospective cohort study. SETTING This study used an administrative claims database in Kumamoto Prefecture, Japan, from April 2012 to February 2017. PATIENTS We identified patients who were admitted to the ICU and received rehabilitation. Eligible patients were divided into those who underwent rehabilitation within 3 days (early rehabilitation group) and after 4 or more days of ICU admission (delayed rehabilitation group). Propensity score matching analyses were conducted to compare the number of outpatient consultations within 1 year and 3 years after discharge from the index hospitalization, total duration of hospitalization after discharge, healthcare costs, and survival. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 6,679 patients were included in the study. Propensity score matching created 2,245 pairs. No difference was observed in the number of outpatient consultations 1 year after discharge, although there were differences between the groups 3 years after discharge. Long-term observation revealed a shorter overall duration of hospitalization (1.9 vs 2.6 mo; p < 0.001) and lower total costs ($28,159 vs $38,272; p < 0.001), as well as lower average costs per month ($1,690 vs $1,959; p = 0.001) in the early compared with the delayed rehabilitation group. No differences in survival were observed (log-rank test; p = 0.18). CONCLUSIONS Starting rehabilitation within 3 days of ICU admission was associated with shorter durations of future hospitalization and lower healthcare costs. Early rehabilitation for ICU patients might be associated with reduced healthcare resource utilization.
