California Public Patient Discharge Data, January - December, 1998

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 dischared 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）负责收集加州境内持照医疗机构的住院患者数据。该数据集为每一位从加州持照医疗机构出院的住院患者创建一条记录，涵盖综合急性护理、急性精神科、药物依赖康复以及精神卫生类医疗机构的相关住院数据。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障隐私与数据机密性）、入院详情、住院时长、支付来源、诊断结果、伴随病症与手术操作。鉴于数据体量庞大，该数据集被拆分为三个独立文件，分别对应洛杉矶县、南加州与北加州区域。
