The role of private education in the selection of primary care careers in low and middle-income countries. Findings from a representative survey of medical residents in Brazil.

Background: Primary health care (PHC) doctors' numbers are dwindling in high- as well as low-income countries, which is feared to hamper the achievement of Universal Health Coverage goals. As a large proportion of doctors are privately educated and private medical schools are becoming increasingly common in middle-income settings, there is a debate on whether private education represents a suitable mean to increase the supply of PHC physicians. We analyse the intentions to practice of medical residents in Brazil to understand whether these differ for public and private schools.

Methods: Drawing from the literature on the selection of medical specialties, we constructed a model for the determinants of medical students' intentions to practice in PHC, and used secondary data from a nationally representative sample of 4601 medical residents in Brazil to populate it. Multivariate analysis and multilevel cluster models were employed to explore the association between perspective physicians' choice of practice and types of schools attended, socio-economic characteristics, and their values and opinions on the profession.

Results: Only 3.7% of residents in our sample declared an intention to practice in PHC, with no significant association with the public or private nature of the medical schools attended. Instead, having attended a state secondary school (p = 0.028), having trained outside Brazil's wealthy South East (p < 0.001), not coming from an affluent family (p = 0.037), and not having a high valuation of career development opportunities (p < 0.001) were predictors of willingness to practice in PHC. A low consideration for quality of life, for opportunities for treating patients, and for the liberal aspects of the profession were also associated with future physicians' intentions to work in primary care (all p < 0.001).

Conclusions: In Brazil, training in public or private medical schools does not influence the intention to practice in PHC. But students from affluent backgrounds, with private secondary education, and graduating in the rich South East were found to be overrepresented in both types of training institutions, and this is what appears to negatively impact the selection of PHC careers. With a view to increasing the supply of PHC practitioners in middle-income countries, policies should focus on opening medical schools in rural areas and improving access for students from disadvantaged backgrounds.
