Are we there yet? Closing the gap of prostate cancer presentation disparities in Ireland

Abstract

Abstract Introduction The Irish Prostate Cancer Outcomes Research (IPCOR) Study collected longitudinal data on men newly diagnosed with Prostate Cancer (PC). Understanding the nuances of disease presentation is essential, considering the high incidence of PC in Ireland. This study aims to characterise disease presentation features, identify factors related to socio demographic disparities in presentation following opportunistic screening, and shed light on potential inequality challenges within Ireland’s healthcare structure. Methods Data were collected on demographics, diagnosis, and treatment of 6,816 men newly diagnosed with PC across 16 hospitals in the Republic of Ireland from February 2016 to January 2020. A complete case analysis was carried out, complemented by a sensitivity analysis for addressing sites with high rates of missing values. Multivariable logistic regression was conducted to examine the association between various predictor variables and the initial presentation to the urology clinic subsequent to opportunistic screening. Results A multivariable logistic regression model revealed that the type of hospital was a key determinant in post-opportunistic screening presentation, with patients in public hospitals 45.7% more likely to be presented following screening compared to those in private hospitals. Urban residents were 34% more likely to present following screening than rural ones. Age negatively influenced presentation following screening likelihood, decreasing by 3.4% yearly. Discussion Our research has highlighted the key features of PC presentation in Ireland, revealing potential inequalities affecting mainly urban populations, middle socioeconomic groups, and individuals with inadequate healthcare coverage. While the differences we observed in various groups may appear subtle and may indicate the success of the Rapid Access Prostate Clinics, they are still significant in pinpointing specific populations that require special attention. Conclusions By addressing these nuanced differences in access to healthcare, socioeconomic status, and urban versus rural residence and implementing tailored strategies, we can work towards closing disparity gaps in PC, ultimately leading to improved health outcomes and equity across all population segments.
