Having lived in Thailand for more than ten years, I believe that this paper has substantial shortcomings in its research methodology and that this has led to very misleading conclusions by its authors.
In terms of methodology, the authors appear to have relied solely on government data. They have avoided considering issues of quality and sustainability, which would have required that they actually spend
considerable time in Thailand.
By neglecting to consider quality of service, the authors have ignored the fact that hospitals, public and private, frequently refuse to treat patients altogether under the 30 baht program. Regardless of people's needs, many hospitals simply tell people, “you are fine, go home and rest.”
Contrary to the authors' findings, supply constraints are a serious issue for public hospitals in Thailand. As a reported 13.6 million uninsured people became newly covered over 2001 to 2005, there has been an influx of
patients into public hospitals. This has resulted in long queues for services as well as an exodus of doctors seeking lower workloads and better pay at private hospitals.
It is simply not true that “informal payments” are not being made in the national health care system. As many doctors in public hospitals also work in private clinics and private hospitals, they readily present their
patients with a dose of medical reality. Patients can either wait for a considerable time to be served at a public hospital, which has old or inadequate equipment, or they can pay up for quality service at a private clinic or private hospital.
