Quality in Australian Health Care Study (QAHCS) Reanalysed Database

QAHCS comprised a review of medical records of over 14,000 admissions in Australian hospitals in 1992, and estimation of the proportion of hospital separations associated with adverse events. For the purposes of the study, an adverse event was defined as an unintended injury or complication which results in disability, death or prolonged hospital stay, and is caused by health care management (rather than the patient's disease). Data on each adverse event identified in the review is contained in the database including information on the nature of the harm experienced by the patient and its consequences, and information on the circumstances in which the harm occurred.QAHCS involved review of hospital medical records for 14,179 admissions to 28 hospitals in New South Wales and South Australia in 1992.

QAHCS涵盖1992年澳大利亚医院逾14000例入院病例的病历回顾，以及与不良事件（adverse event）相关的出院病例比例的估算。本研究中，不良事件（adverse event）被定义为因医疗管理（而非患者自身疾病）引发、导致残疾、死亡或住院时间延长的非预期损伤或并发症。数据库收录了回顾中识别的每例不良事件数据，包括患者所受伤害的性质及其后果，以及伤害发生的情境信息。此外，QAHCS还涉及1992年新南威尔士州与南澳大利亚州28家医院14179例入院病例的住院病历回顾。
