We used flexible parametric survival analysis with restricted cubic splines to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between SRH and mortality in the entire cohort.

Lower SRH at baseline was associated with cancer incidence (HR<sub>good SRH</sub> 1.14, 95% CI 1.08– 1.20 and HR<sub>poor SRH</sub> 1.44, 95% CI: 1.32– 1.58). Poor baseline SRH was associated with increased mortality for women who received a cancer diagnosis (HR<sub>poor SRH</sub> 1.20, 95% CI 1.04– 1.39), and SRH showed a strong association with increased mortality for women who stayed cancer free (HR<sub>good SRH</sub> 1.59, 95% CI 1.44– 1.77 and HR<sub>poor SRH</sub> 3.34, 95% CI 2.91– 3.84).<br/><strong>Conclusion:</strong> Lower SRH at baseline predicted increased cancer risk and all-cause mortality in middle-aged to older women. Poor SRH at baseline predicted all-cause mortality in women who later received a cancer diagnosis.

We described variation in health services utilization and need for surgery among children with IBD between six and 60 months following IBD diagnosis across Canadian pediatric centers and evaluated the associations between care provided at diagnosis at each center and the variation in these outcomes.&lt;br/&gt;&lt;strong&gt;Patients and Methods:&lt;/strong&gt; Using population-based deterministically-linked health administrative data from four Canadian provinces (Alberta, Manitoba, Nova Scotia, Ontario) we identified children diagnosed with IBD &lt; 16 years of age using validated algorithms. Children were assigned to a pediatric center of care using a hierarchical approach based on where they received their initial care. Outcomes included IBD-related hospitalizations, emergency department (ED) visits, and IBD-related abdominal surgery occurring between 6 and sixty months after diagnosis. Mixed-effects meta-analysis was used to pool results and examine the association between center-level care provision and outcomes.&lt;br/&gt;&lt;strong&gt;Results:&lt;/strong&gt; We identified 3784 incident cases of pediatric IBD, of whom 2937 (77.6%) were treated at pediatric centers. Almost a third (31.4%) of children had ≥ 1 IBD-related hospitalization and there were 0.66 hospitalizations per person during follow-up. More than half (55.8%) of children had ≥ 1 ED visit and there were 1.64 ED visits per person. Between-center heterogeneity was high for both outcomes; centers where more children visited the ED at diagnosis had more IBD-related hospitalizations and more ED visits during follow-up. Between-center heterogeneity was high for intestinal resection in Crohn’s disease but not colectomy in ulcerative colitis.&lt;br/&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; There is variation in health services utilization among children with IBD and risk of undergoing intestinal resection in those with Crohn’s disease, but not colectomy among children with ulcerative colitis, across Canadian pediatric tertiary-care centers.

They require lifelong treatment and receiving high quality care is important for preventing complications. We determined if outcomes of children with IBD was different across Canada. We also tested if differences in care at diagnosis was related to outcomes. More than three-quarters of children with IBD were treated at pediatric hospitals.

Real-world databases can be valuable for supporting such research, but fitness for regulatory purpose must first be vetted. Here, we demonstrate a fit-for-purpose assessment of the Japan Medical Data Center (JMDC) claims database for pregnancy safety regulatory decision-making.<br/><strong>Patients and Methods:</strong> The Duke-Margolis framework considers a database’s fitness for regulatory purpose based on relevancy (capacity to answer the research question based on variable availability and a sufficiently sized, representative population) and quality (ability to validly answer the research question based on data completeness and accuracy). To assess these considerations, we examined descriptive characteristics of infants and pregnancies among females ages 12– 55 years in the JMDC between January 2005 and March 2022.<br/><strong>Results:</strong> For relevancy, we determined that critical data fields (maternal medications, infant major congenital malformations, covariates) are available. Family identification codes permitted linkage of 385,295 total mother–infant pairs, 57% of which were continuously enrolled during pregnancy. The prevalence of specific congenital malformation subcategories and maternal medical conditions were representative of the general population, but preterm births were below expectations (3.6% versus 5.6%) in this population. For quality, our methods are expected to accurately identify the complete set of mothers and infants with a shared health insurance plan. However, validity of gestational age information was limited given the high proportion (60%) of missing live birth delivery codes coupled with suppression of infant birth dates and inaccessibility of disease codes with gestational week information.<br/><strong>Conclusion:</strong> The JMDC may be well suited for descriptive studies of pregnant people in Japan (eg, comorbidities, medication usage). More work is needed to identify a method to assign pregnancy onset and delivery dates so that in utero medication exposure windows can be defined more precisely as needed for many regulatory postapproval pregnancy safety studies.<br/><br/><strong>Keywords:</strong> routine health care data, international databases, database evaluation<br/>","PeriodicalId":10362,"journal":{"name":"Clinical Epidemiology","volume":"67 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139647582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
