Disparities in access to breast, colorectal, and cervical cancer screening programmes have intensified during the pandemic period. Findings of a health equity audit conducted by the Pavia Healthcare Protection Agency (Lombardy Region, Northern Italy)

OBJECTIVES: to evaluate the disparities in access to cancer screening programmes in the Province of Pavia (Lombardy Region, Northern Italy), along with identifying the factors influencing these disparities; to assess the impact of the pandemic emergency on invitation and screening coverage in the three organized screening programmes, which are provided free of charge to the target population. DESIGN: observational retrospective study covering both the pre-pandemic and the pandemic periods. SETTING AND PARTICIPANTS: for breast cancer screening, the eligible population comprises women aged 45 to 74; colorectal cancer screening is offered to men and women aged 50 to 74; cervical cancer screening is tailored based on women age. The management of all three screening programmes is overseen by the Health Protection Agency of Pavia, which proactively invites the eligible population through invitation letters. MAIN OUTCOMES MEASURES: for each screening programme, the examination coverage (the number of screened individuals out of the total eligible population) was analysed considering its influencing factors, with a specific emphasis on equity-related factors such as demographics (sex, age), geographic factors (country and continent of birth, residential district), comorbidities. RESULTS: the SARS-CoV-2 pandemic has led to a reorganization of healthcare services and to a reduction of the offer, resulting in an overall reduction in test coverage for all three programmes (-16.3% for breast and colorectal cancer screening, -8.5% for cervical cancer screening). The disparities in coverage among various population groups, reflecting inequalities in access, further escalated from the pre-pandemic to the pandemic period. Noteworthy, equity-related predictors of reduced screening access were non-Italian nationality and residency in rural or mountainous districts. CONCLUSIONS: during periods of healthcare system strain, such as the pandemic, disparities in access can become more pronounced. It is crucial to implement measures for enhancing access to screening in a more equitable manner.

Population-based breast cancer screening in Pavia (northern Italy) in 2016-2018: Key performance indicators and sensitivity estimate.

BACKGROUND AND AIM: This study aims to assess the quality of the population-based breast cancer screening programme in Pavia, northern Italy computing its key performance indicators and estimating its sensitivity for the years 2016-2018. METHODS: Invitation and examination coverage, participation rate, recall rate, detection rate and positive predictive values were computed on the basis of data provided yearly to the Italian Ministry of Health. Sensitivity was estimated identifying interval cancers in the local Cancer Registry and computed with the proportional incidence method. RESULTS: In 2016-2018 the adjusted invitation coverage was 90%, and the adjusted participation rate was 62%. Recall rate was 8.4% for first screenings and 3.9% for subsequent ones. The number of screen-detected cases was 268, corresponding to a detection rate of 6.6‰ for first screenings and 4.6‰ for subsequent screenings. The number of interval cancers observed was 110 over the study period; the proportional incidence was 22% for the first interval year and 50% for the second interval. The overall sensitivity of the screening program was 64%. CONCLUSIONS: The analysis of performance indicators and sensitivity estimates for the Pavia programme indicates that the programme performance is in line with the quality standards set by the European Union and the Italian reference scientific society (GISMa).
