From my experiences in governmental or private hospitals, at least in the bigger cities, the doctors and nurses do their very best. The health system is much better than in the real third world. However, in very special issues, treatments and surgeries, knowledge, equipment and medicine yet didn't reach the level of more specialized hospitals/clinics in more advanced countries (Japan or Switzerland for instance). Some people travel to Thailand to get a better treatment but some Thai people travel to Japan for difficult surgeries if they may afford.
