The Healthcare Accreditation Institute (HAI) to introduce the translated Hospital Survey on Patient Safety Culture in Thai. This survey, consisting of 42 items measuring 12 safety culture areas, evaluates hospital staff opinions on patient safety issues, medical errors, and event reporting. It was later integrated into Thailand's health system in 2019 as a quality development tool. By encouraging personnel participation, the survey helps assess the safety culture of self-operating hospitals and supports ongoing improvements in patient safety.
