Global disparities in cancer supportive care: An international survey.

Abstract

The global cancer burden is rising, particularly in low- and middle-income countries (LMIC), highlighting a critical research gap in understanding disparities in supportive care access. To address this, the Multinational Association of Supportive Care in Cancer (MASCC) Health Disparities Committee initiated a global survey to investigate and delineate these disparities. This study aims to explore and compare supportive care access disparities between LMIC and High-Income Countries (HIC). An online cross-sectional survey was conducted among active members of MASCC. Members, representing diverse healthcare professions received email invitations. The survey, available for 3 weeks, comprised sections covering (1) sociodemographic information; (2) clinical service/practice-related disparities in their region/nation; (3) population groups facing disparities within their region or country. Chi-squared or Fisher's exact test for cross-sectional analyses, and a multivariable logistic regression model was employed for statistical analysis. A total of 218 active members participated, with one-quarter (26.6%) from LMIC and 18.4% ethnic minorities, timely cancer care (43.7%) and timely supportive care (45.0%) emerged as the most pressing disparities globally. Notably, participants from LMIC underscored cancer drug affordability (56.4%) and supportive care guideline implementation (56.4%) as critical issues. Economically disadvantaged populations were noted as more likely to face disparities by both LMIC and HIC (non-US-based) respondents, while US-based respondents identified racial/ethnic minorities as facing more disparities. This global survey reveals significant disparities in cancer supportive care between LMIC and HIC, with a particular emphasis on medication affordability and guideline implementation in LMIC. Addressing these disparities requires targeted intervention, considering specific regional priorities.
