    Abstract Introduction The efficacy of early surgery in preventing complications among Japanese elderly patients with hip fractures requires further investigation. This study aims to use a comprehensive Japanese hip fracture case database to determine whether surgery within the day of admission and the following day reduces the incidence of complications and mortality during hospitalization in elderly hip fracture patients. Materials and methods We retrospectively analyzed the Japanese National Administrative DPC (Diagnosis Procedure Combination) database from April 2016 to March 2022. Approximately 1100 DPC-affiliated hospitals consistently provided medical records with consent for research. The study investigated the association between postoperative pneumonia, deep vein thrombosis, pulmonary embolism, and mortality during hospitalization after propensity score matching, focusing on surgeries conducted on the day of admission and the following day. Results After one-to-one propensity score matching for age, gender, and comorbidity, we identified 146,441 pairs of patients who underwent surgery either within the day of admission and the following day or after the third day of admission. Surgery on the third day or later was independently associated with increased risks of pneumonia, deep vein thrombosis, pulmonary embolism, and mortality during hospitalization with risk ratios of 1.367 (95% CI 1.307–1.426), 1.328 (95% CI 1.169–1.508), 1.338 (95% CI 1.289–1.388), and 1.167 (95% CI 1.103–1.234), respectively. Conclusion A comprehensive study of elderly Japanese patients with hip fractures in the DPC database showed that surgery on admission and the following day is crucial for preventing complications like pneumonia, deep vein thrombosis, pulmonary embolism, and mortality during hospitalization.

    BACKGROUND: /Objectives: Pediatric acute pancreatitis (AP) is not as rare as previously thought, and an increased incidence thereof has been reported. We aimed to clarify the trends and clinical characteristics of pediatric AP in Japan. METHODS: We utilized the Japanese Diagnosis Procedure Combination inpatient database for patients admitted between April 2012 and March 2021, and extracted the data of patients whose principal diagnosis was AP (ICD-10 code K85) or in whom AP accounted for most of the medical expenses. Patients were classified into pediatric (≤18 years) and adult (age >18 years) groups. RESULTS: We included 3941 AP cases in pediatrics and 212,776 in adults. AP cases accounted for 0.08 % of all admissions in pediatrics and 0.33 % in adults, with upward trends during the study period. The proportion of AP patients among all admissions was increased with advancing age in pediatrics. Compared to adults, pediatric AP patients had a smaller proportion of severe cases (22.9 % vs. 28.7 %; P < 0.001), fewer interventions for late complications (0.2 % vs. 1.3 %; P < 0.001), shorter hospital stays (mean 16.6 days vs. 18.0 days; P = 0.001), lower overall mortality (0.7 % vs. 2.9 %; P < 0.001), and lower mortality in severe cases (1.3 % vs. 5.6 %; P < 0.001). Pediatric cases were more frequently transferred from other institutions and treated at academic hospitals than adults (both P < 0.001). CONCLUSIONS: There was an upward trend in the proportion of AP among all admissions in pediatrics, with a lower risk of complications and mortality than adult cases.

    Although proton-pump inhibitor (PPI) administration was reported to be effective in preventing delayed bleeding after gastric endoscopic submucosal dissection (ESD), its effectiveness in esophageal ESD is still unknown. We assessed whether PPI or vonoprazan administration was effective in preventing posterior hemorrhage after esophageal ESD. This retrospective cohort study used the Japanese Diagnosis Procedure Combination (DPC) database, and patients who underwent esophageal ESD between January 2012 and December 2020 were enrolled. The participants were divided into two groups: patients who were prescribed PPI or vonoprazan (PPI or vonoprazan group) and those who were not prescribed PPI (no acid suppression). Propensity score matching analysis was performed, and the delayed bleeding rate was compared between the groups. We analyzed 54,345 patients, of whom 8237 (15.16%) were in the no acid suppression group and 46,108 (84.84%) in the PPI or vonoprazan group (PPI: 34,380 and vonoprazan: 11,728). Delayed bleeding occurred in 1126 patients (2.07%). A total of 8237 pairs were created after matching. Delayed bleeding was not significantly different between the no acid suppression group and PPI or vonoprazan group, respectively (odds ratio: 1.20, 95% confidential interval: 0.93-1.54, P = 0.227). A sub-analysis according to the dose of PPI or vonoprazan, tumor location, and prescription of antithrombotic or anticoagulant medications was performed, but no significant effects of PPI or vonoprazan administration were found. PPI or vonoprazan did not prevent delayed bleeding; thus, the prescription of PPI and vonoprazan after esophageal ESD may not be recommended for the prevention of delayed bleeding.

    OBJECTIVE: Data on risk factors for otogenic intracranial complications including cerebral abscess have been limited. Using a nationwide database, the aim was to identify the factors related to mortality and delayed discharge. STUDY DESIGN: Retrospective. SETTING: Nationwide database using the Diagnostic Procedure Combination database. MAIN OUTCOME MEASURES: Data of 145 patients were extracted from a Japanese inpatient database between 2012 and 2020. The main outcome was survival at discharge. In a subgroup analysis of the 137 surviving patients, the second outcome was delayed discharge. RESULTS: The mortality rate was 5.5% (8 of 145). Logistic regression analyses identified intracerebral complications (adjusted odds ratio [OR], 3.09) and more than 2-day delay of the first surgery after admission (adjusted OR, 4.68) as risk factors for mortality. Specifically, consciousness level evaluated by the Japan Coma Scale (JCS) was significantly related to prolonged hospitalization or mortality: JCS I (adjusted OR, 3.40) and JCS ≥II (adjusted OR, 25.1). CONCLUSIONS: Although otogenic intracranial complications are rare, and their mortality is decreasing because of the progress in imaging and clinical strategies, they remain the most severe complications of suppurative otitis media and/or cholesteatoma. Consciousness level at admission, comorbid diabetes mellitus, and a greater than 2-day delay of surgical intervention were related to prolonged hospitalization or mortality.

    OBJECTIVE: Electrolyte disorders are among the important conditions negatively affecting the disease course of neuromyelitis optica spectrum disorder (NMOSD). Possible mechanisms may include renal tubular acidosis (RTA) accompanying Sjögren's syndrome (SS), syndrome of inappropriate antidiuretic hormone secretion (SIADH), and central diabetes insipidus (DI). Currently, the overlap profiles between these conditions remain uncertain. METHODS: This cross-sectional study collected data from the nationwide administrative Diagnosis Procedure Combination (DPC) database and evaluated the overlap profiles. RESULTS: Among the 28,285,908 individuals from 1203 DPC-covered hospitals, 8477 had NMOSD, 174108 had SS, 4977 had RTA, 7640 had SIADH, and 24,789 had central DI. Of those with NMOSD, 986 (12%) had SS. The odds ratio (OR) for a diagnosis of NMOSD in those with SS compared with those without was 21 [95% confidence interval (CI), 20-23]. Overlap between NMOSD and SS was seen both in males (OR, 28 [95% CI, 23-33]) and females (OR, 16 [15-17]) and was more prominent in the younger population. Among patients with SS, the prevalence of RTA was lower in patients with NMOSD compared with those without NMOSD. Patients with NMOSD showed a higher prevalence of SIADH (OR, 11 [7.5-17]; p < 0.0001) and DI (OR, 3.7 [2.4-5.3]; p < 0.0001). Comorbid SS in NMOSD was associated with a higher prevalence of DI. CONCLUSIONS: Patients with NMOSD are likely to have SS, SIADH, and central DI. RTA in SS does not facilitate the overlap between NMOSD and SS. SS in NMOSD may predispose patients to DI.

    INTROODUCTION: Primary sclerosing cholangitis (PSC) is a rare disease, especially in Asian countries. PSC often develops during ulcerative colitis (UC). Little is known about the severity of PSC in patients with UC. Thus, this study aimed to investigate the impact of concomitant UC on the clinical course of patients with PSC using a nationwide database in Japan. METHODS: We collected data on patients who were admitted for PSC using a nationwide database and divided eligible admissions according to concomitant UC (PSC-UC group vs. PSC-alone group). We conducted propensity score matching and compared the rates of liver transplantation, biliary drainage, and other clinical events between the two groups. We also conducted a multivariate analysis to identify the clinical factors that affect biliary drainage, cholangiocarcinoma, and liver transplantation. RESULTS: We enrolled 672 patients after propensity score matching. The rate of liver transplantation in the PSC-UC group was lower than that in the PSC-alone group (2.2 vs. 5.4%, p = 0.002), whereas the rate of biliary drainage did not differ between the two groups (38.1 vs. 33.8%, p = 0.10). On multivariate analysis, concomitant UC was identified as a clinical factor that decreased the risk of liver transplantation (odds ratio = 0.40, 95% confidence interval: 0.23-0.68, p = 0.0007). DISCUSSION: Concomitant UC in patients with PSC may decrease the risk of liver transplantation. The milder disease activity of PSC with UC is more likely compared to that of PSC without UC.

    IMPORTANCE: Peripartum suicide attempt is a major psychiatric complication associated with pregnancy, but the risk factors remain largely uncertain. OBJECTIVE: To identify the demographic characteristics and predisposing risks for peripartum suicide attempts and postpartum depression. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used retrospective data on pregnant women who delivered children between April 1, 2016, and March 31, 2021, at 712 hospitals in Japan. The nationwide Diagnosis Procedure Combination database was used. EXPOSURES: Psychiatric and nonpsychiatric medical history, age, alcohol and tobacco use, and obstetric complications and procedures. MAIN OUTCOMES AND MEASURES: Data on admissions for prepartum suicide attempt and delivery during the same hospital stay and readmissions for depression or suicide attempt within 1 year post partum were collected. Comparisons of prevalence of each study variable were performed, and multivariable logistic regression analyses were used to determine risk factors. RESULTS: From a total of 39 908 649 hospitalization episodes, 804 617 cumulative pregnant women (median [IQR] age at childbirth, 33 [29-36] years) who delivered at the enrolled hospitals were identified, including 1202 who were admitted for suicide attempt and delivery during the same hospital stay and 111 readmitted for suicide attempt within 1 year post partum. Risk factors associated with prepartum suicide attempts included younger age (adjusted odds ratio [aOR], 0.99; 95% CI, 0.98-1.00) and histories of personality disorder (aOR, 10.81; 95% CI, 5.70-20.49), depression (aOR, 3.97; 95% CI, 2.35-6.70), schizophrenia (aOR, 2.89; 95% CI, 1.52-5.50), and adjustment disorder (aOR, 2.66; 95% CI, 1.07-6.58). Risk factors associated with postpartum suicide attempts included younger age (aOR, 0.96; 95% CI, 0.93-1.00), heavy tobacco use (aOR, 23.09; 95% CI, 5.46-97.62), and histories of alcohol use disorder (aOR, 163.54; 95% CI, 28.30-944.95), personality disorder (aOR, 10.28; 95% CI, 3.29-32.10), anxiety disorders (aOR, 8.13; 95% CI, 2.88-22.98), depression (aOR, 7.27; 95% CI, 2.95-17.91), schizophrenia (aOR, 5.77; 95% CI, 2.17-15.38), bipolar disorder (aOR, 3.98; 95% CI, 1.36-11.67), and insomnia (aOR, 3.17; 95% CI, 1.30-7.78). On sensitivity analysis, risk factors associated with postpartum depression after excluding those with prenatal depression included histories of personality disorder, adjustment disorder, bipolar disorder, insomnia, and anxiety disorders. CONCLUSIONS AND RELEVANCE: The findings of this cohort study suggest that histories of smoking and prenatal psychiatric disorders are potential risk factors for peripartum suicide attempts and may require additional treatment and prevention interventions.

    BACKGROUND AND AIM: The incidence and prevalence of psychiatric disorders are elevated in patients with inflammatory bowel disease (IBD). Whether psychiatric disorders could affect the clinical course of IBD is uncertain and controversial. We aimed to evaluate the impact of psychiatric disorders, particularly depression, on the clinical course of IBD using a nationwide database in Japan. METHODS: We collected data on admissions with IBD using the Diagnosis Procedure Combination database system introduced in Japan. We divided eligible admissions into IBD with and without depression groups using propensity score matching and compared the rates of surgery, use of molecular targeted drugs and biologics, systemic steroid administrations, and in-hospital death. We also conducted a logistic regression analysis to identify clinical factors affecting surgery, the use of molecular targeted drugs and biologics, and systemic steroid administrations. RESULTS: The rates of surgery, use of two or more molecular targeted drugs, systemic steroid administrations, and in-hospital deaths in the ulcerative colitis (UC) with depression group were higher than in the UC without depression group. Multivariate analysis of UC showed that depression increased the odds of systemic steroid administrations, use of two or more molecular targeted drugs, and surgery. However, analysis of Crohn's disease showed that only steroid administrations were associated with depression. CONCLUSION: Our study demonstrated an association between a worse clinical course of UC and depression. Although this result indicates that depression might be associated with increased disease activity in patients with UC, the causal relationship is still unclear. Further prospective studies are warranted.

    BACKGROUND AND AIM: Acute pancreatitis (AP) is a rare extraintestinal manifestation of inflammatory bowel disease (IBD). Several studies from Western countries have reported that the severity of AP in patients with IBD is similar to that in the general population; however, its severity in patients from Eastern countries in the era of biologics remains unclear. This study aimed to investigate the severity of AP in patients with IBD and the effect of biologics on the severity of AP using a nationwide database. METHODS: We divided 1138 eligible AP admissions from the Diagnosis Procedure Combination database system into IBD and non-IBD groups after propensity score matching, and compared the severity of AP. We divided the IBD group into ulcerative colitis (UC) and Crohn's disease (CD) subgroups and compared each with the non-IBD group. Logistic regression analysis was conducted to identify the clinical factors affecting acute pancreatitis. RESULTS: IBD and UC groups had lower rate of severe AP compared to the non-IBD group (13.7% vs 28.3%, P < 0.0001 and 11.0% vs 28.3%, P < 0.0001, respectively). There were no differences in the rates of severe AP between the CD and non-IBD groups. Multivariate analysis showed that biologics did not affect the severity of AP. CONCLUSION: The severity of AP in patients with IBD may be lower than that in the general population; biologics for IBD may not worsen its severity. Further prospective studies are required to clarify the severity of AP in patients with IBD.

    BACKGROUND: Ustekinumab (UST), an antibody against the p40 subunit of interleukin-12/23, has been proven to be effective in patients with Crohn's disease (CD). However, large, long-term comparative studies of UST against anti--tumor necrosis factor (TNF) agents are lacking. We compared the effectiveness of anti-TNF agents and UST in CD patients without prior use of biologics. METHODS: We used a large nationwide anonymized Japanese database containing administrative medical claims data and various related patient data. In a propensity score-matched cohort with similar clinical characteristics, 2-year effectiveness was compared between patients treated with infliximab or adalimumab (anti-TNF group) and those treated with UST (UST group). Primary outcomes were cumulative rates of hospitalization, surgery, and persistence. RESULTS: Among 53 540 CD patients, 7047 were extracted for eligibility, of which 5665 were treated with an anti-TNF agent and 1382 with UST. After propensity score matching, the cumulative hospitalization rates were comparable between anti-TNF and UST groups (P = 0.85; 25.3% vs 26.5% at 1 year, 33.8% vs 39.8% at 2 years). The cumulative surgery rates were also comparable between these groups (P = 0.46; 5.5% vs 5.1% at 1 year, 8.3% vs 8.4% at 2 years). The persistence rate at 1 year was higher in UST group (90.8% vs 92.5%), and that at 2 years was higher in anti-TNF group (81.2% and 74.6%); however, there was no significant difference in the cumulative persistence rate (P = 0.55). CONCLUSIONS: Anti-TNF agents and UST appear to have comparable effectiveness for CD patients without prior use of biologics.

    BACKGROUND AND AIMS: Self-expandable metallic stent (SEMS) is widely used for obstructive colorectal cancer (OCC). Both SEMS and urgent surgery have several merits and demerits. This study aimed to clarify the efficacy of SEMS by comparing the mortality rate after the hospitalization between SEMS and urgent surgery for OCC. METHODS: We collected OCC patients' data using the Diagnosis Procedure Combination (DPC) database system. We divided eligible patients into the SEMS and urgent surgery groups using propensity score matching and compared in-hospital death rates, length of hospitalization, and medical costs. We also conducted logistic regression analysis to identify clinical factors affecting in-hospital deaths. RESULTS: We enrolled 17 140 cases after propensity score matching. SEMS reduced the in-hospital death rate compared with urgent surgery (2.0% vs 3.6%, P < 0.0001). Length of hospitalization was shorter in the SEMS group than in the urgent surgery group (16 vs 25 days, P < 0.0001). Medical costs were lower in the SEMS group than in the urgent surgery group (1 663 550 vs 2 424 082 JPY, P < 0.0001). Multivariate analysis also showed that SEMS reduced in-hospital death (odds ratio = 0.58, 95% confidence interval: 0.50-0.70, P < 0.0001). CONCLUSION: Self-expandable metallic stent placement for OCC might reduce the mortality rate in short term and shorten the length of hospitalization. These results facilitate considering SEMS with careful judgment for its indication when treating OCC patients.

    BACKGROUND: Early recognition and management of baseline risk factors may play an important role in reducing glaucoma surgery burdens. However, no studies have investigated them using real-world data in Japan or other countries. This study aimed to clarify the risk factors leading to trabeculectomy surgery, which is the most common procedure of glaucoma surgery, of glaucoma patient using the Japanese nationwide administrative claims data associated with the diagnosis procedure combination (DPC) system. METHODS: It was a retrospective, non-interventional cohort study. Data were collected from patients who were admitted to DPC participating hospitals, nationwide acute care hospitals and were diagnosed with glaucoma between 2012 to 2018. The primary outcome was the risk factors associated with trabeculectomy surgery. The association between baseline characteristics and trabeculectomy surgery was identified using multivariable logistic regression analysis by comparing patients with and without trabeculectomy surgery. Meanwhile, the secondary outcomes included the rate of comorbidities, the rate of concomitant drug use and the treatment patterns of glaucoma eye drops at the index admission. Among patients with trabeculectomy surgery, the risk factors leading to cataract surgery were also evaluated as subgroup analysis. RESULTS: A total of 29,599 patients included in the analysis, 12,038 and 17,561 patients were in the glaucoma surgery and non-glaucoma surgery cohorts, respectively. The factors associated with the increase in trabeculectomy surgery were having allergies, taking concomitant drugs including cancer, depression, ischemic heart disease and peptic ulcer, being diagnosed with primary open-angle glaucoma and longer length of stay in hospital. In contrast, the factors associated with the decrease in trabeculectomy surgery were having hypertension, taking hypertension drug, age ≥ 80 and female. CONCLUSIONS: Special focus on Japanese patients with glaucoma who have allergy-related comorbidities or take immune, nervous, circulatory or gastrointestinal system-related concomitant drugs seems to be desirable.

    In order to elucidate the influence of emergency hospitalization of obstetric patients on the hospital management, we used 12-month data, including the DPC (Diagnosis Procedure Combination) data, obtained from a public hospital (A) and conducted a comparative analysis of planned and emergency hospitalizations, an analysis of factors that might influence the fees for medical services, and an analysis of neonates admitted to the hospital with some disease in cases where the payment system of the fee for Caesarean delivery was transitioned from a fee-for-services payment to the DPC. The results of the analyses revealed that the fees for medical services decreased by 1% in emergency hospitalizations, but increased by 3% in planned hospitalizations where the payment was transitioned to the DPC system. It was found that emergency hospitalization was a factor that decreased the fees for medical services when the payment system was transitioned from the fee-for-services payment to the DPC. It was also estimated that the fees for medical services in neonates who were admitted to the pediatrics department with disease decreased by about 8% in the case where mothers were emergently hospitalized, and decreased by about 12% in the case where mothers underwent planned hospitalization. It was considered important to give consideration to the ratio balance between planned and emergency hospitalizations in patients undergoing Caesarean delivery and monitor the occurrence rate of medical events, including emergency hospitalizations, that would place the hospital management at a disadvantage and decrease the income.

    本年度（3年目）は、厚生労働省保険局より取得したNDBレセプトデータ（集計表情報）および官公庁公開データの解析を行った。その成果は学会にて報告され、現在、老年医学に関する英文誌へ投稿中である。 データに関して、NDBレセプトデータは、「都道府県」を単位とした「集計表情報」として平成29年度の医科入院・医科入院外・DPCの各データに含まれる「転帰が死亡のがん患者」を対象とし、都道府県別・性別・年代別（65歳以上・65歳未満）の3区分を分類軸に、在宅看取り割合を推計できるよう取得した。 官公庁公開データは、「地域別変数」として「1世帯あたり人員数」など４種類、「地域別の医療資源（人口10万人対）」として「DPC算定病床数」、「療養病床数」など5種類、そして「レセプト情報による診療行為の性・年齢調整済み地域差、Standardized Claim-data Ratio、SCR」として「往診料」、「在宅患者訪問診療料」など5種類を収集した。NDBレセプトデータと官公庁公開データは都道府県を単位として連結するかたちでデータベース構築し、解析を行った。 集計結果より、在宅看取り割合に係る都道府県別の統計量は、平均値26.3％、標準偏差6.1％、最小値14.3％、最大値42.1％となり、全体で約3倍の開きがあることが分かった。また、解析結果より、都道府県別の在宅看取り割合への増高要因として「在宅患者訪問診療料のSCR」が、低減要因として「DPC算定病床数」、「療養病床数」がそれぞれ挙げられた。 以上より、在宅看取り割合は都道府県別に一定の開きがあること、および在宅看取り割合の増高要因として在宅患者訪問診療料の算定が多いこと、低減要因として急性期および慢性期の病床数が多いこと、がそれぞれ挙げられることが分かった。在宅看取り推進への条件整備として、訪問診療に係る活動量の充実が挙げられると考えられた。

    We aimed to generate hypotheses about visiting nurses’ conversational structure and quality of explanation to improve end-of-life care quality with terminal cancer patients and their families in home. The research design was a data conversion type of mixed methods study prospective and observational. In the results, the expert visiting nurses tended to ask questions and confirmation of the body and symptoms mainly to the patients for 10 minutes starting the visit. On the other hand, explanations and information on body and symptoms were mainly given to families after 20 minutes of visit, and it was possible to identify a tendency to explain psychological contents to families after 60 minutes. In addition, the contents of psychological and the social system or insurance were communicated with feeling of reassurance. We also could be confirmed that the visiting nurses' conversation contents more matched with families' anxiety, the less the families' anxiety was reduced.
