I don’t know the exact number of health informatician in Thailand. However, the number of this career might not adequate to develop health technology system in this country. For example, I observed that the programmer develop a feast of software in order to assist the health care workers or patients, however, few of that software could be applied practically. We do not evaluate which software is effective while the others are not. Health informaticians could analyze throughout this problem and disseminate the knowledge so that the developer could make the useful software. The challenge of increasing health informaticians includes several factors. Firstly, I could not clearly see the career path of the health informatician whether there is few or it is not well introduced publicly. Secondly, the incentive for health informaticians is not as much as other professional. Thirdly, the course for health informatics is still limited in Thailand. These three factors are challenges for health information in Thailand.
