Adverse events and medical harm comprise major health concerns for people all over the world, including Thailand. The prevalence and burden of medical harm must always be monitored, and a voluntary database should not be used to represent national value. The purpose of this study is to estimate the national prevalence and economic impact of medical harm in Thailand using routine administrative data from the inpatient department electronic claim database under the Universal Coverage scheme from 2016 to 2020. Our findings show that there are approximately 400,000 visits with potentially unsafe medical care per year (or 7% of all inpatient visits under the Universal Coverage scheme). The annual cost of medical harm is estimated to be approximately USD 278 million (approximately THB 9.6 billion), with an average of 3.5 million bed-days per year. This evidence can be used to raise safety awareness and support medical harm prevention policies. Future work should focus on improving medical harm surveillance using better data quality and more comprehensive data on medical harm.

Adverse health care events are a global public health issue despite major efforts, and they have been acknowledged as a complex concern. The aim of this study was to explore the construction of unsafe care using accounts of adverse events concerning the patient, as reported by patients, relatives, and health care professionals. Twenty-nine adverse events reported in an acute care setting in a Swedish university hospital were analyzed through discourse analysis, where the construction of what was considered to be real and true in the descriptions of unsafe care was analyzed. In the written reports about unsafe events, the patient was spoken of in three different ways: (a) the patient as a presentation of physical signs, (b) the patient as suffering and vulnerable, and (c) the patient as unpredictable. When the patient\'s voice was subordinate to physical signs, this was described as being something that conflicted with patient safety. The conclusion was that the patient\'s voice might be the only sign available in the early stages of adverse events. Therefore, it is crucial for health care professionals to give importance to the patient\'s voice to prevent patients from harm and not unilaterally act only upon abnormal physical signs.
