Optimising colorectal cancer screening strategies and target populations in budget-constrained regions through cost-effectiveness analysis: a case from eastern China

Objectives
The primary aim of this study was to optimise colorectal cancer (CRC) screening strategies and target populations in resource-limited areas through cost-effectiveness analysis, evaluating the best screening methods and appropriate screening ages.

Design
A prospective microsimulation model was used for cost-effectiveness analysis, calibrated with real-world data.

Setting
The study was conducted in Huzhou City, Zhejiang Province, China, focusing on primary and secondary healthcare levels. Data were obtained from the Huzhou Center for Disease Control and Prevention.

Participants
The study included 418 805 local residents who participated in the Huzhou screening programme between 2020 and 2022. Inclusion criteria were individuals aged 45–100 years and residing in the local area.

Interventions
Four initial screening methods were evaluated: single-sample immunochemical faecal occult blood test (iFOBT), double-sample iFOBT, single-sample iFOBT combined with a risk assessment questionnaire and double-sample iFOBT combined with a risk assessment questionnaire. Screening frequencies included annual and biennial intervals.

Primary outcome measures
The primary outcome measure was the cost per incremental quality-adjusted life year (QALY) for different screening strategies. Also, the impact on CRC incidence, related deaths, life years saved (LYS) and QALYs was considered.

Results
The primary data were sourced from the Huzhou screening programme, which included 418 805 individuals from 2020 to 2022. All screening strategies were found to be effective, with the cost per incremental QALY being less than $1036, which is below the minimum standard for middle-income countries. The most effective screening strategy was the annual combined two-sample iFOBT and risk evaluation questionnaires. This approach led to a reduction in CRC incidence and related deaths by 2435 and 1174 cases per 100 000 individuals, respectively, and an increase in LYS by 13 903 years and QALYs by 35 564 years. The recommended ages to begin and end screening were 48 and 72 years, respectively.

Conclusions
All CRC screening strategies demonstrated effectiveness compared with non-screening, with the annual combined two-sample iFOBT and risk evaluation questionnaires emerging as the optimal approach. For additional regions, the best screening strategy can be selected based on the health outcomes and costs we have provided.

Addressing Heterogeneity in the Large-Core Trials: A Case for Standardized Imaging Analysis

Stroke, Volume 56, Issue 5, Page 1339-1342, May 1, 2025. Infarct detection is critically dependent on the imaging modality that is used and the criteria for defining tissue infarction. The recent trials of large-core thrombectomy used heterogeneous imaging methods to identify patients with large ischemic cores. Moreover, the Alberta Stroke Program Early CT Score methodology was not harmonized between the trials. Consequently, the large-core trial populations were distinct. To pool the populations in a clinically meaningful way, data should be pooled by imaging modality and time window. The imaging should be re-adjudicated using standardized criteria for imaging analysis and Alberta Stroke Program Early CT Score grading. This standardized approach can be disseminated into clinical practice so that the pooled treatment effect estimates can guide real-world patient care.

Risk factors for in-hospital mortality in surgical patients with abdominal sepsis in China: a nested case-control study

Objectives
To delineate the clinical characteristics and investigate the determinants that may affect the prognosis of surgical patients with abdominal sepsis.

Design
A case-control study was nested in a cohort of surgical patients with abdominal sepsis between 2008 and 2022. We extracted patient’ medical records to execute descriptive statistical analyses. Multiple logistic regression models and subgroup analysis were employed to elucidate the risk factors of in-hospital mortality.

Setting
Two tertiary hospitals in China.

Participants
476 surgical patients diagnosed with abdominal sepsis between 2008 and 2022 were analysed.

Interventions
None.

Outcome measures
Descriptive statistics were used to examine pertinent patient information, including demographic details, laboratory findings, surgical interventions and anaesthetic records. Multivariate logistic regression was used to identify independent risk factors for in-hospital mortality. Subgroup analyses were conducted to explore the impact of specific clinical characteristics on outcomes.

Results
476 patients diagnosed with abdominal sepsis were analysed, exhibiting an in-hospital mortality rate of 7.56%. Advanced age (OR 6.77, 95% CI 2.46 to 18.66, p
