Thai EMR Standards Part II: The NHSO

NHSO: National Health Security Office is the main organization overseeing healthcare management in Thailand. In the previous article, we discussed how the payment systems differ between government and private healthcare providers. Since government hospitals alone cannot meet all service demands, the private sector also participates in the NHSO’s Universal Health Coverage (UHC) program to fill those gaps.

Both NHSO and SSO allow registered private hospitals and medical clinics to provide services on an accrual basis, where medical service charges are collected later. The NHSO uses a payment model based on Diagnosis-Related Groups (DRGs) for certain types of care. In that model, the main “unit” used for calculation is the adjusted relative weight (adjRW). This unit applies to both registered private healthcare organizations and government hospitals. However, I will explore this system in more detail through the medical service I am most familiar with: Dialysis.

For patients covered by the NHSO, dialysis is required twice a week. From my experience working on the technical side of healthcare operation (including infrastructure, support, and consulting in the Health Information Technology (HIT) field for over a decade); a standard dialysis session takes about three hours. The normal service charge under the SSO is around 1,800 THB, while the private sector’s direct payment or insurance rate is about 2,200 THB. In comparison, the NHSO reimbursement rate is approximately 1,500 THB per session.

This dialysis operation normally involves three main organizations: the NHSO, the CHI (Central Office for Healthcare Information), and the Nephrology Society of Thailand. The software systems from CHI and Nephrothai are mostly developed in-house and are compatible only with Windows. Meanwhile, the NHSO is trying to move its systems toward web-based applications as much as possible.

In practice, these three systems are still not fully integrated. Each organization collects similar data in different formats, which leads to duplication and extra manual data entry. Dialysis centers must submit reports separately to each system, using different forms and software. Although the NHSO has made progress toward online submission and open data formats, the lack of unified standards continues to limit the real potential of digital healthcare management in Thailand.

When a patient needs to be transferred from one clinic to another, a transfer permit is required, which involves a lot of hierarchical procedures. This is because all the systems that store patient information are still closed and not fully interoperable.
