The Influences of SES on Patient Choice of Doctor: A Systematic Review

As patients become increasingly involved in healthcare decision-making, it is important to examine the drivers behind patient choice of doctor (PCOD); the initial decision can have lasting impacts on patients' trust in providers and health outcomes. However, limited studies have explored PCOD relative to socioeconomic status (SES) or health disparity. This review identified similar preferences and varied decision criteria in PCOD across SES groups.

PubMed, PsycINFO, Web of Science, and relevant cross-references were searched for articles published between January 2007-September 2022. Papers were screened using Covidence. Included studies examined PCOD by income and/or educational levels. Analysis was performed in 2022-2023.

From 4,449 search results, 29 articles were selected (16 countries, 14 medical specialties, total of 32,651 participants). Individuals of higher SES ranked physician characteristics (e.g., qualifications, empathy) or performance more important than cost or convenience. Individuals of lower SES often had to prioritize logistical factors (e.g., insurance coverage, distance) due to resource constraints and gaps in knowledge or awareness about options. Despite differing healthcare systems, such divergence in PCOD were relatively consistent across countries. Some patients, especially females and disadvantaged groups, favored gender-concordant physicians for intimate medical matters (e.g., gynecologist); this partiality was not limited to conservative cultures. Few researchers investigated the outcomes of PCOD and indicated that lower-SES populations inadvertently chose, experienced, or perceived lower quality of care.

Patients' decision criteria varied by SES, even under national systems intended for universal access, indicating the impacts of social determinants and structural inequities. Health education supporting patient decision-making and research on how SES affects PCOD and outcomes could help reduce health disparity.
