California Public Patient Discharge Data, January - December, 2001

The California Office of Statewide Health Planning and Development (OSHPD) collects inpatient data from licensed hospitals in California. The dataset consists of a record for each inpatient discharged from a California licensed hospital, including general acute care, acute psychiatric, chemical dependency recovery, and psychiatric health facilities. Items recorded include type of care, demographics (some items are masked to protect privacy and confidentiality), admission details, length of stay, source(s) of payment, diagnosis, conditions and procedures. Because of the amount of data, the data is divided into three separate files; Los Angeles County, Southern California, Northern California.

加利福尼亚州全州卫生规划与发展办公室（California Office of Statewide Health Planning and Development，OSHPD）从加州境内的持牌医院收集住院患者数据。该数据集的每条记录对应一名从加州持牌医院出院的住院患者，涵盖普通急性护理、急性精神科、药物依赖康复以及精神卫生医疗机构的出院病例。记录字段包括护理类型、人口统计学信息（部分条目已做脱敏处理以保护隐私与机密性）、入院详情、住院时长、付费来源、诊断结果、伴随病症与诊疗操作。由于数据体量庞大，该数据集被拆分为三个独立文件：洛杉矶县、南加州、北加州。
