Primary health concept revisited: where do people seek health care in a rural area of Vietnam?

The government of Vietnam is committed to promote and secure equity in access to health care for all citizens. The current rapid changes towards a market economy may challenge the government's wish for maintaining equity, especially for low income and vulnerable groups. The aim of this study was to investigate aspects of access and utilisation of health care of rural people. The study included a random sample of 1075 out of the 11,547 households in the Field Laboratory in Bavi district, northern Vietnam and a structured questionnaire was used. The results indicate that self-treatment is common practice and private providers are an important source of health services not only for those who are better off but also for poor households. The costs for health care are substantial for households, and lower income groups spent a significantly higher proportion of their income on health care than the rich did. The poor are deterred from seeking health care more often than the rich and for financial reason. As regards sources for payments, the poor relied much more on borrowing money to pay for their health care needs, while those who are better off relied mostly on household savings. A burden of high cost for treatment implies high risks for families to fall into a 'medical poverty trap'. Our findings suggest a need for developing risk-sharing schemes (co-payment, pre-payment and insurance), and appropriate allocation of scarce public resources. We suggest that the private health care sector needs both support and regulations to improve the quality and access to health care by the poor.
