Analysing Inequalities in Colorectal Cancer Screening Using an Individual Socioeconomic Status Index.

An individual socioeconomic status index (ISESI) was used to analyse inequalities in participation and colonoscopy acceptance in the Valencia Region Colorectal Cancer Screening Programme (VR-CRCSP). This is a cross-sectional study of men and women aged 50-69 who had been invited to participate in the VR-CRCSP as of February 2020 (N = 1,066,763). The variables included in the ISESI were nationality, employment status, disability, healthcare coverage, risk of vulnerability, and family size.

Interaction of sedentary behaviour and educational level in breast cancer risk.

Objective: This cross-sectional study aims to analyse the relationship between sedentary behaviour and breast cancer (BC) risk from a social perspective.

Methods: Women aged 45-70 who participated in the Valencia Region Breast Cancer Screening Programme (2018-2019) were included, with a total of 121,359 women analysed, including 506 with cancer and 120,853 without cancer. The response variable was BC (screen-detected) and the main explanatory variable was sedentary behaviour (≤2 / >2-≤3 / >3-≤5 / >5 hours/day, h/d).

Impact of different age ranges on the benefits and harms of the breast cancer screening programme by the EU-TOPIA tool.

Background: The recommendation for the implementation of mammography screening in women aged 45-49 and 70-74 is conditional with moderate certainty of the evidence. The aim of this study is to simulate the long-term outcomes (2020-50) of using different age range scenarios in the breast cancer screening programme of the Valencia Region (Spain), considering different programme participation rates.

Methods: Three age range scenarios (S) were simulated with the EU-TOPIA tool, considering a biennial screening interval: S1, 45-69 years old (y); S2, 50-69 y and S3, 45-74 y.

Interval Cancer in Population-Based Colorectal Screening Programmes: Incidence and Characteristics of Tumours.

The objective of this study is to evaluate interval cancer (IC) in colorectal cancer (CRC) screening, which is CRC diagnosed in an individual after having received a negative faecal occult blood test and before the next invitation to participate in screening. A follow-up study was conducted on a cohort of participants in the first three screening rounds of four colorectal cancer screening programmes in Spain, = 664,993. A total of 321 ICs and 2120 screen-detected cancers (SCs) were found.

Time costs of waiting, doctor-shopping and private-public sector imbalance: microdata evidence from Hong Kong.

Objective: To quantify the disutility of waiting for a specialist consultation and to examine whether individuals' willingness-to-pay (WTP) to reduce waiting time is associated with doctor-shopping behavior in outpatient clinics of four large, public hospitals in Hong Kong.

Methods: We performed a cross-sectional survey of 6495 outpatients on public sector waiting lists enrolled from July 2000 to October 2001. Main outcome measures were WTP to reduce queue time and odds ratios (ORs) for doctor-shopping according to WTP status.

Waiting time, doctor shopping, and nonattendance at specialist outpatient clinics: case-control study of 6495 individuals in Hong Kong.

Objective: Nonattendance is a major health services research and management issue that has received little attention or systematic study in Asia. We examined the independent associations between waiting time, doctor shopping, and nonattendance in specialist outpatient clinics of 4 large public hospitals in Hong Kong.

Research Design: Case-control study.
